The best smartphones with a powerful battery. The right choice of a good battery for your phone or smartphone Battery for a smartphone what should be

You take out your phone to make a call or use the GPS, and suddenly you see the message “Battery low”. Familiar situation, right?

Batteries in phones - once and today

Remember the need to "format" the battery? Discharging your phone three times before completely shutting down and then charging for 12 hours? This was very important for nickel cadmium (Ni-Cd) and nickel metal hydride (Ni-MH) batteries.

This behavior was supposed to protect them from the “memory effect” and the “lazy battery effect”. Both problems were to reduce the capacity of the battery while maintaining a real reserve. lazy battery effect was reversible and caused less performance loss. The battery could be fixed by connecting it to a special charger with a discharge function. memory effect causing more problems because it forced you to replace the battery with a new one.

Then they began to use lithium-ion batteries (Li-Ion), which are still popular today. You will find them in most smartphones available, as well as in many other devices: laptops, tablets, e-book readers. Their main advantages are: fast charging, long service life, higher performance and smaller size.

The most efficient type of battery, which is increasingly found in smartphones and other electronic devices, is currently lithium polymer (Li-Poly) batteries. They are very roomy and charge much faster than standard Li-Ions. In this regard, manufacturers willingly install them in flagship smartphone models.

ma*h is the unit in which the capacity of the battery is indicated? It means the amount of energy that the device will absorb in 1 hour. In other words, a capacity of, for example, 3000 mAh means that within an hour your smartphone will absorb 3000 milliamps.

What parameters determine battery endurance

The number of matches is only one of the elements. The operating time of the phone is also affected by its other features. If you need a smartphone with a reliable battery, pay attention not only to the battery capacity of the model, but also to the screen size. It is the ratio of these two values that will tell more about the subsequent battery life in this model - due to the fact that the screen consumes the most power.

An important issue is also the performance of the central processor. Mid-range components tend to use less power. However, it is worth knowing that the latest mobile processors with high performance also manage energy better thanks to appropriate optimization.

How to increase battery life

Formatting a Li-Ion and Li-Poly Battery

Batteries currently in use do not require formatting. In the case of Li-ion and Li-polymer, partial charging works much better - for example, from 40 to 80%. Try also to avoid a complete discharge.

Our following tips will help you with this:

Screen backlight

The screen consumes the most energy. You should decrease its brightness. A lower backlight level will significantly reduce battery consumption. Most smartphones also have a built-in light sensor that automatically adjusts the brightness of the display according to lighting conditions, which is supposed to save energy.

However, remember that too frequent changes in the backlight level in some smartphones, on the contrary, can drain the battery even faster. It is worth checking how this feature works on your smartphone.

Auto-rotate screen

If your smartphone's battery doesn't last all day, consider turning off the auto-rotate screen feature.

Changing the orientation drains the battery because the phone uses the accelerometer to determine the position. If you disable it, you will reduce the use of this sensor and power consumption.

Widgets

Allows you to quickly access frequently used functions, but consumes more power. This is because they require frequent updates. You should limit their number, or use widgets with a manual update function.

Screen Timeout

Screen automatically turns off after 15-30 seconds. The less you work, the more energy you save. Reducing the display timeout will allow you to noticeably increase the operating time of your phone.

Standby mode

The standby mode itself also consumes a lot of energy. The phone does not work, but is ready to start at any moment. Questions often appear on the Internet on how to turn off standby mode. This cannot be done! But you can stop applications running in the background, displaying notifications, using Wi-Fi and determining the location.

If you care about saving battery power, switch your phone to flight mode (offline mode), in which all networks are turned off, you cannot receive calls, sms and notifications from the application. Thanks to this, you save the charge of your smartphone.

Automatic synchronization

Thanks to it, you do not have to check every time if there are new messages in your mailbox or update the widget with the weather forecast. However, this requires a systematic connection to the Internet and checking email. You can disable this feature altogether.

Another way is to reduce the clock frequency. You will find this option in the phone system (or in the settings of each application).

Data transfer

Another point is to turn off data transfer (over a cellular network or Wi-Fi), as well as other communication options (Bluetooth, NFC) when you are not using them. You can also select the desired network type (2G or 3G) in the mobile network settings (Settings - Mobile Networks), instead of switching between 2G / 3G / 4G automatically. In this way, you will avoid frequent network searches, which also consume the battery.

On some smartphones, you can also choose which applications can use the connection. Limiting their number will certainly help save energy.

Also remember to turn off automatic updates. Much better to do it manually when you get a notification. Don't ditch it entirely - new versions of apps can be much better optimized for battery usage.

Remove also unused programs. Otherwise, the system launches them and they run in the background. If you can't remove them, use the Disable option. You can find it in the menu when you hold the app icon or in your smartphone settings.

Games can consume a lot of power, especially those that require active location, data transfer, and an always-on display. If the battery in your phone leaves much to be desired, you should stop using such demanding games, or...

Buy Power Bank

This is a compact device that will provide your smartphone with an additional charge of energy. Some PowerBanks are keychain-sized gadgets that fit easily into your pocket. Particularly popular are devices with a volume of 8400 to 10050 mAh, which allow you to perform several recharging cycles.

Save energy with a task manager

Android has a lot of apps running in the background so they can launch quickly. This results in additional energy consumption. Some people recommend using a task manager (so-called "task killer"), which kills the application in the background, saves memory, and as a result, saves battery power.

In practice, it looks a little different. The Android system is designed to make efficient use of RAM. There, it stores some of the applications in order to turn them on faster, consuming fewer resources than when loading from scratch. The task killer will disable the application completely, which means that restarting it will require more resources and energy.

The second question is that the Android operating system may try to restore the application, which also consumes the battery. In addition, remember that Android closes applications that have not been used for a long time, which saves RAM and battery. For normal use, this is sufficient.

The same is true for the iPhone and the iOS platform. Most applications running in the background are not actually running ("frozen") and do not consume power. Much more energy will be required to start programs from scratch.

Applications to extend battery life

There are many applications on the market that allow you to monitor the battery status of your phone and save energy. See which are worth looking into.

Fast battery charging

Manufacturers offer more and more smartphones with Quick Charge (also known as Super Charge or Turbo Power), which allows you to fully charge the battery within a few tens of minutes. All you need is a phone and charger that support this technology.

This is a very useful solution if you lead a very active lifestyle and are often away from a power source. If you forget to connect your smartphone to the charger at night, you will have time to charge it in the morning, even just before going out.

Just a few minutes is enough to charge the battery to a level that will last for another 8-9 hours of operation.

The multitude of features combined with the large screen is a big challenge for the phone's battery. We hope that our advice will help you in increasing its service life.

And what methods do you use to extend the battery life of your smartphone? Share with us. We look forward to your comments.

The mobile phone is now an important accessory. Most people cannot imagine life without it.

It helps you stay in touch with family and friends. You can call the ambulance, the police and the fire department anywhere, not just from home.

Mobile phones have certainly contributed to the communications revolution. The problem is fast battery drain.

It happens that the battery has already been so heavily exploited that it is tempting to choose a new model.

Then the problem may arise, what to look for when choosing a battery for your phone? What should be its parameters, the most important?

Phone batteries - how to choose

After a while, when the mobile phone works hard, it is necessary to replace the battery.

They work for about two years and should be replaced. Otherwise, they will not work well.

This means that you need to recharge it very often. The more you charge the battery, the sooner it will need to be replaced.

Although in any case, the time will come when a spare battery becomes necessary. Especially when the phone is a working tool.

First of all, you should think about where you can buy it. This can be done in GSM stores, online auctions or virtual stores.

Let's remember that choosing in the Internet space will save you a few cents.

Due to the huge selection of mobile phone batteries in stores, it is difficult to choose a specific type.

Obviously, it should fit your mobile phone. Most people look at maximum power and price when choosing a battery.

Sorry, but cheap ones, where the manufacturers say they have a large capacity, in fact, this is a hoax.

With a large capacity, such as 4000 mAh, the workmanship will be very poor. Also, the cheapest cell phone batteries are often not covered by the manufacturer's warranty.

Some types of batteries have a limited capacity in their case. When choosing the battery capacity for a mobile phone, it is best to use your own common sense.

A full-fledged product above average performance, of course, does not cost a few rubles. If this is the case, then most likely the battery parameters are not compatible with the real ones, so it is better not to decide to choose such a battery.

Deciding to choose a new battery, you should first of all pay attention to its type. It is better to choose Li-Ion or Li-polymer.

These batteries are built on modern materials, which allows you to charge at any time. This means that you do not have to wait until it is completely discharged, as was the case with older types.

Secondly, an important parameter is the battery capacity. It can be up to about 1500-1800 mAh, while with lithium polymer batteries the capacity is higher, at about 2500 mAh.

It is also indicative which company manufactured the battery. The stores have a very wide selection of manufacturers and brands, which makes it very difficult to buy them.

After a detailed analysis of the market, it turned out that only a few manufacturers can offer us a reliable, good quality product.

Charging is an important parameter. The manufacturer indicates, for example, that the battery will work flawlessly up to 1000 charges.

Of course, you must use a suitable power source for charging. In the beginning, you need to charge the battery to full, or even continuously for 20 hours.

Then charge the battery with a discharged one. This procedure must be repeated at least 2 times as the battery will then be formatted.

You must always use the correct charger. You should look at the charger and it is best that it does not take more than two hours.

Lithium-ion batteries have an automatic charging interruption system when the battery is fully charged.

You must charge the battery using only original chargers - others may damage the electronics contained in the mobile phone.

If you buy a battery made by an independent manufacturer, you should check whether it is equipped with a protection circuit, a thermostat, and the case is resistant to cracking.

Popular battery manufacturers

One of the most famous and at the same time the best manufacturer is TF1. Its production adheres to very strict quality standards.

It provides up to 2 years of warranty, and the parameters indicated on the label are fully consistent with what is located directly under the case.

In addition to this company, Nokia, Samsung, Siemens, Sony Ericsson, Motorola, etc. are also major companies.

The list of mobile phone battery manufacturers also includes such companies as: Activejet, Apple, Ansmann, Blackberry, Cluestar, Batimex, Blue Star, Belkin, Cisco, Cipher Lab, Datalogic, Dexim, ENERGIZER, Extreme, FOOF, Fonmedia, Fujicell, Garmin , GSmart, Gigabyte GT, GPU, HiCapacity HP. Hipower, HTC, Honeywell, Intermec, JustMobile, Kensington, LG, LXE, MaxPower, MyPhone, Panasonic, Prestigio, Pulsar, Tellsson, TelForceOne, Uniross, Unitech, Whitenergy, China.

Questions before choosing

How often do you need to change the battery in your mobile phone?

Generally speaking, with average cell phone usage, the battery should be replaced every two years.

Of course, if the phone is not so often used, the exchange can be done after 3 or 4 years.

What are the signs of replacement?

Initially, the battery starts to work less. Later, power is required every day, then every few hours until the battery is depleted after each call.

If you see that your cell phone battery is draining very quickly over time, you should consider getting a new battery.

In addition, you should properly handle it to prolong its life.

You should never choose a battery that is assigned high performance, in particular capacity, but low price.

As a rule, its quality is low and the power is at least half as much as indicated on the package label.

It is better to choose a slightly more expensive, but proven manufacturer's reputation, which gives a guarantee.

Then get a guarantee that the battery will represent a decent level of quality corresponding to the price. I also recommend watching a good video below. Good luck.

Universal external batteries, or power banks, are not such a complicated technique that you can get confused in them. We will tell you how to choose an external battery for your phone - which one will best be able to power your devices even on a long hike.

How to choose an external battery for a smartphone? Main characteristics

Capacity

The main parameter by which you should choose an external battery is, of course, its volume. It depends on it how long it can power your devices. Modern power banks have a capacity of 2,000 to 50,000 mAh. But the principle “a lot means good” does not work here: with an increase in capacity, the size and weight of the battery increase.

The most comfortable for daily wear will be a battery with a capacity of 5000 - 10,000 mAh - this is if you want to charge only one device and do not go far from home. If you need an independent power source for several devices, or you plan to be away from the outlet for a long time, it is better to pay attention to external batteries with a capacity of 20,000 - 30,000 mAh.

Charging current

The second important characteristic is what current the device is capable of producing at the output. The higher the current, the faster the battery will charge. But charging batteries too quickly is not entirely correct: they can overheat and fail faster. For an average smartphone, a device with a charge current of 1-2 A is enough, for tablets and laptops, 2-3 A is required.

The optimal charging current can be "peeped" on the charger that comes with the gadget. As a rule, gadget electronics limit the maximum current for safety reasons, so weak devices are unlikely to burn out from powerful charging.

The most successful option is a power bank with two ports that give different output current. For example, one port can deliver 1 A, the other 2 A - a couple of external batteries for a smartphone with such an opportunity, we will tell you at the end of the article.

But most often, the manufacturer indicates the total current that the device can give out - that is, when two smartphones are connected, each is given 1 A, a total of 2 A. Keep this in mind!

Ports and cables

Devices are connected to the powerbank via USB ports using bundled cables and adapters. Take another look at your devices and ask yourself two questions:

First of all, how many devices do you want to charge at the same time? The same number of ports, ideally, should be on an external battery.
Secondly, what devices do you have? If you have an iPhone, the power bank should have a Lightning connector, if you have an old iPhone, you will need an adapter from Apple 30-pin to USB. To connect other devices to an external battery, you may need USB to microUSB, USB Type-C adapter cables, or a DC-DC cable (for a laptop).

Cables can be supplied with the power bank, but if necessary, they can, of course, be purchased separately. In addition, there are external batteries with attached sets of adapters, including those for peculiar connectors like the same Apple 30-pin.

Charging type

Important question - how do you intend to charge the power bank itself. A good external battery has a microUSB connector for self-charging. Accordingly, you can even charge it with a smartphone charger (keep in mind that with a small charging current, this will take a long time). You can also use any other connector - for example, a computer port, a USB socket or a car cigarette lighter.

But there are alternative options - for example,. Then you can replenish energy reserves by simply leaving it in the sun for a few hours - and then charge your gadgets from it. For long hiking trips to nature, such a device will come in handy, and it will come in handy in the country. In addition, this is a minus one gadget that will draw energy from your outlet.

Special requests

The four characteristics mentioned above are common when choosing any power bank. However, besides this, there are many interesting additional options that an external battery for a smartphone can have - how to choose the right ones is up to you:

Charging laptops. Such a power bank can produce enough voltage to recharge the battery of your laptop. External batteries with this function are often equipped with DC inputs, as well as voltage switches that allow you to increase and decrease it: after all, a laptop needs a voltage of about 20 V to charge, and a smartphone “eats” only 5 V - the comparison here is clearly not in favor of the “laptop” . Of course, such devices are quite large.
fast charging. Powerbank can support fast charging functions: Qualcomm 2.0, 3.0 or 4.0, as well as proprietary technologies - Samsung FastCharging, Meizu mCharge, Asus BoostMaster. And both for devices and for yourself - in order to replenish your reserves as quickly as possible.
Wireless charger. Power banks with this feature have a transmitter that is supported by new smartphones. In order for the phone to start charging, it will be enough to put it on top of such a power bank - no cables are needed.
Protection against dust and moisture. Some powerbank designs have gone through and are rated up to and including IP68. Take an interest in this characteristic if you need a really secure external battery (perhaps for your super-secure smartphone,).
Information display. On it you can see the remaining charge in the power bank, the current voltage, current and other important information.

In addition, a power bank can have a cute design and an unusual shape, be supplied with accessories - complete cables, adapters, a cover or a storage case, and some models can even be used as a flashlight.

The modern market is just teeming with a huge variety of smartphones that you can buy. Different price categories, colors, models of characteristics, with each new day there are more and more different designs and manufacturers. However, the most important feature that unites all models is battery power. Today we will talk about the battery capacity of the phone - which is better, and what nuances you should pay attention to when buying a new gadget. How many hours does the popular battery last? How to choose how many hours it lasts and what the phone battery is measured in.

Technical feature of the power supply

When buying a mobile device, each person thinks about what size phone battery is best, what kind of battery and why is one of the main characteristics of any gadget?

Important! According to its design features, a smartphone is very similar to a tablet. The volume of the battery they can be the same, and therefore can be different. This is due to the fact that during operation our mobile device is used for cellular communication. That is why battery consumption is spent, first of all, on this nuance, and only then on Bluetooth, Wi-Fi and similar services.

All of the above nuances include the fact that an increasing number of people are on social networks from a mobile device and regularly view the feed. As a result of the long operation of the screen, the Internet and cellular communications, which can work in data transfer mode, the consumption of the power source increases several times.

Based on all the above facts, it is worth getting yourself a phone that is characterized by a good battery capacity for a smartphone.

Choosing the best capacity for a smartphone

In today's market, you will find mobile communication devices with different battery capacities. It should vary from 1.5 to 5000 milliamps.

Important! This indicator is conditional. So, modern mobile devices can have a low battery capacity, but at the same time work very quickly. This is due to the fact that all models are equipped with powerful processes, and the software is perfectly optimized. When deciding which battery capacity is best for a smartphone, one must take into account the fact that even with a small indicator, autonomy can be large. However, this rule applies exclusively to expensive models.

On the other hand, you need to look at gadgets with the Android operating system. The fact is that budget models are produced with such a base. As a result, the battery charge may run out in half a day, or at night the phone will turn off for some unknown reason, at first glance.

In any case, regardless of the operating system, it is better to purchase models with the highest rate. It's pretty easy to decide:

If the box says that the power source contains 200-2500 mAh, then the gadget will be able to work for a day.
An indicator equal to 300-4000 mAh symbolizes that you will charge the gadget once every two days.
If you are thinking about buying a mobile device with a rate of 5000 milliamps, then you can charge the phone once every six to seven days.

Important! Before you buy a modern gadget and think about which battery is best for a smartphone, you need to take into account the factor for which purpose you are purchasing it:

If you need to read a book and only talk on the phone, the minimum amount may be enough.

For constant listening to MP3 Player, games, watching movies, you should purchase devices with a battery capacity of at least 3000 - 4000 mAh (mah).

Choosing the best smartphone by manufacturer:

Among a variety of manufacturers, a good battery capacity for a smartphone is from the manufacturer of the Samsung brand.
It should also be noted the excellent work of the Microsoft trademark. Please note that the volume indicators on these devices are true. So, if the volume is 2500 milliamps, then you will charge the gadget once every two to three days.
Models with good batteries include HTC, Lenovo, Asus, and Acer.

Important! If you want to buy yourself a Chinese “fancy” phone, then take models that cost at least $200. Remember that you can count on high-quality components only if the manufacturer of the equipment has really proved itself worthy in the market. Therefore, looking closely at the new gadget in terms of battery characteristics, click on the link so that you no longer have any doubts about which manufacturer is better to choose a smartphone.

How to reduce battery consumption?

If you are still thinking about what battery capacity is best for a smartphone, then you should know what nuances the main battery charge is spent on.

The main consumers of the charge:

display;
data transfer;
cellular.

Tips for reducing battery consumption on modern models:

Turn on data transfer only when you need to. Turn off after use.
Reduce display brightness.
Delete unused apps. It can be either open at the moment or downloaded, but rarely used.
Turn off your phone at night or use the Airplane feature.
Turn on battery saver when your phone is set to allow it.

Also on our portal you will find many useful tips on how to increase phone battery life.

Extending battery life

Despite the fact that we figured out the battery issue, you need to monitor the charge and extend its life.

You need to charge up to 100%.
Don't waste your battery. Connect the charger to it when the energy indicator is 40-50%.
In no case do not put the phone plugged into the mains at night.
As soon as the phone reported a full charge, unplug it.
Use only original chargers.
Do not charge phones and put them near heaters, heating elements and under the influence of sunlight. All devices do not like high temperatures.
Once a month, to prevent the controller, it is worth completely discharging the battery and charging it up to 100%.

Important! Separately, read about how to properly charge your smartphone so that its battery lasts longer.

The battery is an integral part of the mobile phone, which provides it with autonomous operation. How often you need to use the charger will depend on the correct use of the battery, as well as the capabilities of your phone.

Types of batteries

There are three main types of batteries used in mobile phones: nickel cadmium, lithium ion and lithium polymer. In fact, there are more of them, but the rest of the species have not received mass distribution, so we will leave them outside the scope of this article.

Nickel-cadmium batteries were once very popular, but today they are almost abandoned due to the detrimental effect on the environment and a number of other disadvantages. Modern mobile phones do not use them, unless you find such a battery in some very old model. At one time, their mass distribution was due to low cost, but otherwise they had a number of negative qualities: fast self-discharge, low capacity-to-physical size ratio, strong heating during operation. Nickel-cadmium batteries have a so-called "memory effect", due to which they have to be fully charged and discharged regularly for several cycles in a row. This effect is manifested when they begin to recharge a battery that has not yet completely drained. This leaves a charge that cannot be used, and as a result, the battery life of the device is reduced. For nickel-cadmium batteries, on average, more than 1000 charge-discharge cycles are typical.

The most widespread in modern mobile devices are lithium-ion batteries. They are more durable and less harmful to the environment than nickel-cadmium, and at the same time they have a much higher energy density: with a modest physical size, they have a relatively high capacity. They do not have a “memory effect”, they are characterized by a low self-discharge rate. The disadvantages of this type of batteries include aging (even if they are not used for their intended purpose), so it is not recommended to buy them for future use. Better yet, pay attention to the production date when buying a new lithium-ion battery. This type of battery does not require any special maintenance, but with proper storage (in a charged state) and operation in compliance with the temperature regime, it will last much longer. For lithium-ion batteries, on average, from 500 to 1000 charge-discharge cycles are typical.

Lithium polymer batteries are an improvement on lithium ion batteries, but at a lower cost. They feature high energy density, slow self-discharge, and are even more environmentally friendly. Like lithium-ion batteries, they are subject to gradual aging. For lithium-polymer batteries, on average, from 500 to 600 charge-discharge cycles are typical.

Features of battery operation

The following reasons can shorten the life of most batteries or completely render them unusable:

non-compliance with the rules of operation (hypothermia, overheating, moisture ingress);
physical damage to the contact group;
self-opening the battery at home;
frequent falls and bumps;
recharging the battery with the phone on;
replacing the battery with the phone on;
regular long-term recharging (more than a day in the on state);
long-term storage without operation.

Any of the three types of batteries considered loses its capacity over time and must be replaced after 2-3 years of continuous operation. This is a normal process - do not scold manufacturers for a low-quality product, which often lasts much less than the mobile phone itself. If it becomes necessary to replace, you should choose more expensive branded batteries, and not cheap fakes, since the savings in this case can be very doubtful.

You should also be aware that the location of the base stations of the mobile operator can significantly affect the battery life of your device. The farther away the station, the more power is required to receive the signal and the faster the battery needs to be recharged.

Choosing a phone depending on battery capacity

Today on sale you can find phones that are equipped with batteries with a capacity of 800 to 1500 mAh. There are phone models with a battery capacity outside this range, but they are rather the exception to the rule.

When buying a phone and pre-calculating its battery life, you should correctly evaluate the capabilities of the mobile device as a whole. The fact is that not every phone or smartphone with a battery capacity of 1300-1500 mAh will work for weeks on end, everything can be just the opposite. The manufacturer usually indicates in the specifications of the device not only the battery capacity, but also the battery life in continuous talk on the phone and in standby mode. In the first case, it is usually 5-8 hours, in the second - about two weeks. But these are dry numbers for extreme cases - in fact, we understand that no one will talk for hours or just look at the phone all day long. Therefore, the actual operating time of the phone will depend on its technical characteristics and battery capacity, and not on any one factor.

Usually, the simpler the phone, the longer it can work without recharging. The main part of "long-playing" phones are typical monoblocks that have the most common screen with a diagonal of up to 2 inches and do not imply the constant use of wireless communications (Bluetooth modules, Wi-Fi, GPS, etc.). The battery capacity for most of these devices is small (up to 1000 mAh), but the lack of energy-intensive functions and modules under moderate load allows you to recharge it about once every 5-7 days. By moderate load, we mean daily calls for 30-50 minutes, 2-3 sent/received messages, 1-2 pictures taken by the camera, about half an hour of work with additional applications (browser, organizer, audio player).

Mobile phones and smartphones with touch screens are very popular today. They are modern and comfortable, but they cannot work for a long time without recharging. Large touch screens (and most often they have 3-4 inches diagonally) are very energy-intensive, besides, the hardware platform (if we are talking about a smartphone) gives a significant load. In addition, touch phones are more often used for checking e-mail, laying a route, transferring data, viewing multimedia content - all these features additionally “eat up” a fair amount of battery capacity. With rare exceptions, the schedule for smartphones with touch screens is as follows: work during the day, recharge in the evening.
