How to prevent your phone from dying. What to do if the battery runs out quickly on Android

With the problem of discharging too quickly battery(battery) almost all users of mobile gadgets encounter. The problem occurs gradually and goes unnoticed for some time, but one day the owner notices that time battery life smartphone or tablet has almost halved. If you do nothing, it will decrease further - until it becomes impossible to use the device. And one day the device won’t turn on at all.

Let's talk about why the battery on Android devices drains quickly and how to extend its life.

Reasons for rapid battery discharge

• The actual battery capacity of a smartphone or tablet is lower than indicated in the specifications.
• Battery capacity has decreased due to normal wear and tear.
• Ambient temperature is below +5 ⁰C or above +30 ⁰C.
• Turned on too high level screen brightness.
• Resource-intensive features included: GPS, NFC, Bluetooth, etc.
• Long distance to base station mobile operator.
• Energy is consumed by those working in background applications and widgets.
• Frequent turning on and off of the device.
• Infection with mobile viruses.
• A malfunction of the operating system or hardware, as a result of which certain resource-intensive functions or the device itself are not turned off.

Battery capacity is lower than in the passport

The discrepancy between the actual battery capacity and the indicator indicated in the passport of a smartphone or tablet is more common than you think. It’s just that very few users decide to double-check it. Most believe documents, as well as program indicators, which also do not always display reliable data.

The reason for the discrepancy between actual information and nominal information does not always lie in deception on the part of the manufacturer or seller (although this also occurs); lithium power supplies simply lose their capacity during long-term storage. If you bought a device that was released a year ago, even if proper storage its battery has become less capacious by 2-6%, and when incorrectly charged (that is, when charged to 100%) - by as much as 15-30%.

To calculate the actual capacity of the battery, use charger-discharge devices, like iMAX, or homemade dischargers complete with a multimeter or USB tester. The exact indicators are determined during the discharge of a fully charged battery.

If your phone's battery capacity is less than stated, it means it will drain in a shorter time than expected. And, alas, it is impossible to influence this.

Capacity has decreased over time

Battery wear becomes noticeable after 1.5-2 years of using a smartphone or tablet. But it may happen earlier if:

• use the device often and for a long time at low and very high air temperatures (the most favorable temperature for operating lithium batteries is room temperature);
• allow discharge close to 0%.
• charge the device near heat sources;
• store the unused battery at 100% charge at high temperature environment(for storage, the optimal charge level is 40-50% and refrigerator temperature);
• charge the battery with higher voltages and currents than those provided by the manufacturer (the required level of current and voltage is indicated on charger, which was sold complete with the gadget).

Frequent short-term recharging, contrary to popular belief, does not harm the battery. The current with which it is charged has a much greater influence. It is preferable to charge lithium batteries with low currents, although this takes longer.

If the battery capacity of your device has decreased due to wear and tear, the only way solutions - replacing the battery with a new one.

Using the gadget in cold or hot weather

When using a mobile device in unfavorable temperature conditions (up to +5 ⁰C and above +30 ⁰C), the battery discharges noticeably faster, but at temperatures close to room temperature, its capacity is immediately restored to its original level.

If you don't do this too often, the battery won't wear out quickly, but for calls in the cold it's still better to use a headset and keep the phone in a warm pocket.

High screen brightness level

The screen of an Android mobile device is the main consumer of energy. The brighter it is illuminated, the faster the battery drains.

The use of adaptive backlight, which changes depending on the ambient light (available only on devices equipped with a light sensor), helps reduce battery consumption. To enable it, select the “Auto” checkbox in the screen brightness settings. To prevent the screen from remaining on when you are not using the gadget, set it to go into sleep mode after 30-60 seconds of inactivity.

Resource-intensive features

After the screen, the next active consumers of energy are:

• geolocation;
• live (animated) wallpaper;
• NFC and Bluetooth;
• mobile Internet (3G, 4G).
• Wi-Fi.

If they are all on at the same time, even the most capacious battery will drain very quickly, so whenever possible, turn off what you are not using.

Unstable cellular connection

You may have noticed that when you spend a long time in places where the phone has poor reception of the operator's base station signal, for example, outside the city, the battery discharges faster than usual. This happens because more energy is spent maintaining an unstable, intermittent connection.

The battery will drain faster even if the problem occurs with only one of the two SIM cards. To save charge, it is better to disable such a SIM card for a while.

Apps and widgets running in the background

Many Android applications and widgets, after installation, register themselves in autorun and work in the background the entire time the device is turned on. When there are a lot of such applications, the device not only discharges very quickly, but also noticeably slows down, so startup should be kept under control and allowed only to those programs that need it (antivirus, optimization tool, utility utilities, instant messengers, etc.).

Unfortunately, the autorun control functions of custom and system applications not in Android. But it becomes available after receiving root rights(superuser) and installing special utilities on the device, such as:

• Startup Manager and some others

There are utilities that allow you to manage startup without root rights, but they do not work on every gadget and do not always work correctly.

Applications that the user himself launched, but after they were no longer needed, he forgot to close, can also consume battery resources. The accumulation of such programs not only loads, but also heats up the processor, which in turn heats up the battery. And when heated, as we know, the phone battery drains very quickly.

Control over processes that actively consume energy is also best entrusted to special utilities. For example, the following:

• • DU Battery Saver etc.

By the way, most of them include cleaning the system from unnecessary files, processor cooling, charging optimization and a number of other tasks. To keep your device in order, it is advisable to use one of these utilities constantly.

Frequent reboots and turning the device on and off

Wanting to save charge, some users regularly turn off their mobile gadget. Sometimes even several times during the day. This is another reason why the battery drains too quickly, since when the device starts up and the operating system loads, the energy consumption is close to the maximum.

While you are not using your Android smartphone or tablet, you should not turn it off completely - just turn off the screen, complete resource-intensive tasks, disable communication functions (Wi-Fi, GPRS, 3G-4G Internet, GPS, NFC and Bluetooth), background data transfer, sensors and vibration motor. To do this, most mobile gadgets have an energy saving mode, the activation button for which can be located in different sections of the settings (parameters) menu.

Mobile virus infection

Malware that attacks Android devices does not always operate openly. They often carry out activities that are invisible to the user, and the only signs of their presence are empty accounts and very fast discharge batteries, including in standby mode.

Exclude hidden viral infection should be followed in case of any non-standard behavior of the gadget, for example:

• The phone or tablet wakes up from standby mode without any active action on your part.
• The device is in sleep mode and becomes warm.
• On the device without your participation they turn on Wi-Fi modules, geolocation, mobile Internet and others. Or they cannot be turned off.
• Appeared in the list of outgoing calls and SMS unknown numbers, and in your browser history - views of sites that you have not visited.
• An application has assigned itself as a device administrator without your knowledge.
• For unknown reasons, Google stopped launching Play antivirus and other security applications.
• Any system functions have stopped working.
• Volume increased for no reason network traffic devices.

How to find and remove mobile virus, read on our website. The instructions are relevant for Android phones and tablets of the most different brands: Samsung, LG, Xiaomi, Philips, Lenovo and others.

System or hardware failure

Some PC and laptop users have encountered a problem such as incomplete shutdown of the computer, when the screen goes blank when the operating system is shut down, but some devices remain on. active state— the cooler continues to rotate, the indicators light up, etc. The exact same problem occurs on mobile devices, it’s just not so easy to notice, because smartphones and tablets do not have a cooler, and the indicator only shows the charging stage. In the event of such malfunctions, the device essentially remains on constantly and, accordingly, even in a “sort of turned off” state actively consumes battery energy.

The causes of such problems may be faulty applications, viruses, operating system errors and malfunctions in the device’s hardware (including connected devices - memory cards, SIM cards, etc.).

The only symptom that allows one to suspect that the device has not been completely turned off is too much battery consumption at a time when it should be minimal. And to make sure whether this is really your case, just remove the cover of the phone (tablet) and check the processor temperature with your fingers. If the device continues to work after being turned off, its processor will remain warm. Sometimes in this condition the body of the device heats up slightly, but sometimes not - it depends on its design.

In such cases, what can the user do without contacting the specialists:

• Remove applications installed before the problem appeared (if you were able to record the time it started).
• Conduct an anti-virus scan.
• Disconnect all connected devices.
• Reset the system to factory settings.
• Remove the battery (if it is removable), hold down the power button for 20-30 seconds and replace the battery.
• Reflash the device with known working firmware.

After each manipulation, check the gadget by turning it off. If the problem is not solved, you will have to take it to a service center for repairs, since the problem itself will not go away, and the battery will exhaust its life much faster than during normal operation.

With bright screens require a lot of battery power.

But besides the screen, various applications can consume battery energy.

What needs to be done so that the phone does not discharge quickly and its battery lasts as long as possible?

First you need to answer the question: "How do smartphone batteries work?".

Most smartphones have either lithium-ion (Li-ion) battery, or lithium polymer battery (Li-pol), and such batteries do not need to be fully charged and discharged at the very beginning of using the smartphone.

But such batteries can suffer from low voltage problems, so it's best to charge partially (between 20% and 90%) rather than completely charging and discharging.

There is still debate about caring for these batteries, the key is to find what is best for you.

How to increase battery life

Here are some tips on how to make your smartphone battery last longer and not drain quickly:

1. Screensaver and themes in dark colors.

If your device has an AMOLED screen (like most Samsung devices), use dark colors for the screen - this will help save battery power, because AMOLED screens Only colored pixels are illuminated. Black pixels are not backlit, which means the more of them you have, the more energy you save.

2. Don't use automatic brightness.

This feature may seem useful, but automatic brightness usually makes the screen much brighter than it actually needs to be. It's best to set the screen brightness manually and change it whenever you need to. This is very important point, because The screen is a major waste of battery power.

3. Set sleep mode (screen timeout) for the shortest possible time.

Just think, if your screen automatically turns off after 1 minute, it will use 4 times more power than if that indicator stays on for 15 seconds.

Studies have shown that the average user turns on their smartphone 150 times a day, which means everything possible can be done to reduce screen time.

4. Should not be used unnecessary functions, such as animation or smart scrolling, because. they also use up your battery power.

Long battery

5. Turn off vibration.

It is also worth turning off the phone vibrating when you press keys - this may seem interesting function, but it is useless and only consumes energy from your battery. Of course, if you simply need this function, then you can skip this item. It takes more energy to vibrate your phone than to make a simple ringing call.

6. Use notifications for your lock screen.

A lock screen can help save your battery power. And all because you see all notifications at once, without having to turn on the entire screen. This screen comes by default on all smartphones with the Android Lollipop operating system.

If you have operating system Android KitKat (previous version), try using lock screen widgets if your RAM supports this, or you can install an app that does this for you, like Dynamic Notifications.

You will still have to turn on the screen, but it will be on for much less time than usual. In addition, the screen will be dark, which will also save battery power.

7. Set the "Do Not Disturb" function.

This function allows you to activate silent mode, and the user will be notified of all notifications when the phone vibrates.

Also this utility turns off Wi-Fi and Mobile Internet. When you're at work and don't want to be disturbed, set a mode where your phone won't ring or vibrate.

You can also turn on airplane mode when you decide to take a break.

When you install apps like Greenify, the apps you normally run on your phone regularly will shut down and go into "sleep mode" when you're not using them.

Extending the life of your smartphone battery

8. You don't need to be connected to networks 24 hours a day.

Turn off GPS, Bluetooth, Wi-Fi and mobile data when you don't need them. To clarify your location and navigation, you can use either Wi-Fi or 3G, or GPS, but not all together.

9. Try to limit the use of widgets, especially those that require an Internet connection.

Widgets that show the weather, as well as widgets for Twitter, Gmail and some social networks. networks need constant updating, which means they need energy.

It's better to simply turn on a particular widget when you need it, rather than leaving it to run and update on its own.

Over time, Android devices begin to run out of battery much faster than they used to. In some cases, you can fix this problem yourself, and sometimes the only way out The only solution to this situation is to buy a new battery.

There may be several reasons why a tablet or phone stops holding a charge:

Battery boost

This item should only be considered if you are using an old phone or tablet.

This method of eliminating the problem of rapid battery drain is suitable for a nickel-metal hydride (NiMH) battery, which, as a rule, can be installed on older models of phones and tablets. On modern devices install lithium-ion (Li-Ion) batteries that do not require pumping.

To find out what technology your battery is made of, you need to determine the device model or study the information written on the battery itself.

Swinging is a repetition of the cycle of completely discharging and then fully charging the phone several times in a row. Please note that this technology should only be used on nickel batteries; on others it will not only not be beneficial, but will also cause harm.

To boost the battery:

1. When the battery is completely discharged, turn off the device and charge it completely.
2. Remove the battery from the device, keep it in this state for two minutes, and then reinsert it back into place. If the battery is not working properly, a notification will appear on the screen that the phone is not fully charged, for example, 95%. Without turning on the device, repeat the charging process until 100%.
3. Discharge the device completely. Repeat these steps until the battery, after you have removed it and inserted it back, begins to show full charge. The charge level should not drop or change after handling the battery.

Battery calibration

Unlike swinging, calibration is recommended for all batteries if they have been identified as having problems holding a charge. If the device quickly runs out, turns off when the displayed charge level is not zero, or does not charge completely, then it must be calibrated. Thanks to this procedure, the device will understand what it really is. maximum volume battery, and in the future will give it the opportunity to fill completely.

Via a third party application

Since Android does not have a battery calibration application by default, you will have to download it from the Play Market:

Video: calibrating the battery using the Battery Calibration program

No third party programs

To calibrate the device without using third party programs, follow these steps sequentially:

What to do if calibration and buildup did not help

If the methods described above did not help you return the previous charge retention time, then there is only one thing left to do - replace the battery. Batteries are sold separately and can be purchased at most stores that sell phones and tablets. When purchasing, be guided by the model and battery size. Before you pay, check if the battery fits and works with your device model.

Battery care

Try to adhere to the rules listed below to ensure that the battery of any device lasts as long as possible.

Recommendation	Description
Charging lithium-ion batteries	Don't charge lithium ion batteries 100% It is better to do several short recharges than one full one.
Full discharge	Do not allow a complete discharge when the device turns off by itself. Try to charge your phone or tablet on time.
Temperature	Keep your device at a balanced temperature. Do not place it in a very cold or extremely hot area.
Processes and Applications	Disable unnecessary processes and programs immediately after you stop using them.
Charging cable	Keep the cable safe. Try to use only official cables.
Port	Keep the port you connect to clean. charging cable. When wiping it, act very carefully so as not to damage the microcircuits in it.
Do not load the device for a long time and with a large number of heavy applications or games. This causes the phone to become very hot, which has a negative impact on the battery.

Taking care of your battery is very important. This may not extend its service life, but it will definitely prevent it from breaking before the end. warranty period. Follow the above guidelines and remember that lithium and nickel batteries need to be cared for differently.

One of the problems with almost all smartphones is that they discharge too quickly. If one charge lasts you 8-12 hours, you are already lucky! However, often within half a day mobile friend begins to give alarming signals that he is about to leave you. We have prepared for you a selection of 9 proven methods that will help you extend the life of your iPhone. Go!

Turn off WiFi if you don't need it at the moment

Turn off WiFi if you don't plan to use it anytime soon. Your iPhone won't waste power trying to connect to every available WiFi network.

Turn off 3G and cellular data

If you will be using WiFi in the near future or if you don’t need the Internet at all, then turn off 3G communications and cellular data transmission. Thanks to these steps, your iPhone will last an extra 2-3 hours.

Adjust screen brightness

Too much bright screen may cause eye pain. Try to find a comfortable brightness level; it will probably be somewhere in the middle of the slider. If your iPhone is dying, lowering the brightness level to low can help it last a little longer. It doesn't hurt to adjust the auto-brightness according to your individual wishes.

Turn off unnecessary notifications and location for some services

By turning off unnecessary push notifications (and you probably have some), you will not only save battery power, but also save your time and energy, since you will not be constantly distracted by beeping or vibration, indicating that you are in some kind of trouble. The toy was given 100 coins.

Also take a look at the “Geolocation” section. Lots of apps want to track your location, but do you need it? For example, if you haven't looked at your maps in a couple of months, why leave it to the app to constantly monitor your location? This takes too much energy.

Turn off Bluetooth

If you do not regularly use devices that require Bluetooth support, for example, the same Bluetooth headsets, then simply disable this function.

Turn off "Raise to speak" in Siri

"Raise to speak" feature, which includes voice assistant automatically as soon as you raise your hand to the phone, naturally speeds up iPhone drain. If it is unimportant for you, then simply turn it off in Siri settings.

Disable automatic mail checking

Of course, this way you risk missing a super-important letter, because, for example, you simply forget to check your mail yourself, but you will save a lot of energy. By the way, at the same time, while you are in this settings section, disable the “Push” function, which instantly sends messages from mail server to your device.

Advice: if you have several mail accounts, and one of them is so important that you want to instantly receive messages for it, then apply individual settings for each account.

Clear the Quick Access Toolbar

Apple has officially stated that the applications that are in the panel quick access, have virtually no effect on the charge level, since their operation is actually suspended. But maybe it works a little differently in iOS 6, or the idiosyncrasies of some apps have slipped under Apple's radar, but more and more users are claiming that their charge lasts longer when the Quick Access bar is mostly empty.

To remove from it unnecessary applications, double click on Home button, tap on any app icon and hold until you see the delete icon. Then close all unnecessary applications.

Set a shorter auto-lock time

If it is not too important for you that your iPhone is not blocked for as long as possible, then install minimum time blocking - 1 minute. Save a lot of energy.

By using at least one of these methods, you will already help your iPhone to last longer on one charge, and if you use all 9 tips, you will be very surprised at how long-lived your smartphone has become. Of course, you won’t always be able to keep it in this state, because if you turn off the Internet and other functions, then why would you need an iPhone at all? But at times when you only need your phone to receive calls, and saving charge is a priority, these tips will come in handy.

If you have another way to extend the service life of your phone on a single charge, then write to us about it in the comments.

All laptop owners are familiar with the situation when the laptop battery runs out and the owner rushes around looking for an outlet to charge the “tired” gadget. To keep your laptop battery charged as long as possible, there are 15 simple rules, subject to which you can use the device for a long time without recharging.

1. If you think that the battery is draining too quickly and decide to replace it, then you should buy new batteries for laptops only in trusted stores.

2. Reduce the brightness of the logos on the screen to the maximum minimum level, this will optimize the battery performance of your laptop.

3. Reduce the number of programs running in iTunes mode, Desktop Search, etc. All these programs add load to the battery and reduce operating time. It is also recommended to disable all those programs that you use. this moment If you don't use them, they also drain the battery.

4. If possible, reduce the number of external USB devices (including mice) and WiFi connections; it is better to close them or, if they are not in use, remove them. While charging additional devices From a laptop, such as an iPod, battery life is significantly reduced.

6. Launch programs from hard drive, and not from media such as CD / DVD, since the startup process from them is very energy-intensive. If possible, instead optical disks It is better to use programs like Alcohol, which are stored on virtual disks.

7. Clean the battery contacts regularly; this procedure should be carried out every two months with a piece of cloth soaked in alcohol. This makes the process of transferring energy from the laptop battery more efficient.

8. Don't leave your laptop in sleep mode long time, do not allow the battery to become completely discharged.

9. It is not recommended to leave the laptop in standby mode for a long time, although this allows you to resume work from where you left off if necessary. Standby mode consumes a lot of energy and drains the battery.

11. In the panel Windows management you need to adjust the “Power Options” function in order to optimize this process and make the battery power consumption as efficient as possible. You need to select the "Max Battery" mode to achieve maximum effect.

12. Eliminate multitasking from your work, perform only one action. You should not run the program in the background and listen to music at the same time. If only one action is performed, the process of completing data processing is faster.

13. Set the PC requirements as low as possible, so the simplest programs like Email or text editor consume much less energy than games. It is important to set your priorities correctly, especially if your laptop battery is very low.

14. It is worth updating your laptop model from time to time, as developers each time improve the capabilities of devices in order to attract customers, some latest laptops ways to keep your battery charged throughout the day.

15. When using a laptop old model You need to periodically completely discharge the battery and fully charge it; this advice does not apply to new laptop models that use lithium-ion batteries.

In conclusion of the article, we can talk about three more rules, in the form of a bonus, which are also designed to help preserve the battery charge for a laptop for a long time.

Tip No. 1. You need to defragment regularly, the faster it works HDD, the less load there will be on the battery. For Apple systems Mac program OSX is not recommended as it is better suited for performing fragmentation.
Tip No. 2. Disable the autosave function in MS-Word and Excel, this will significantly reduce the load on your hard drive. If the battery is running low, you can turn on autosave again and save your work before the battery dies.
Tip No. 3. Reduce the use of modern graphic editors, as they consume a lot of energy and reduce speed work hard disk.
