If the old "grandmother's phones" could boast of battery life lasting a week, high-tech smartphones live away from the outlet for a maximum of two days. The increase in productivity has led to a decrease in the service life - it is now considered normal to buy a mobile phone once a year. This affects all of its components.
I consider buying a phone a lottery. For example, my old battery swelled after the warranty period. And Mom's Fly has been living in good health for 4 years.
In this article, I will tell you what to do if the battery runs out quickly even in a new phone. Often the wrong gadget settings are to blame, but there are 15 more reasons that we will talk about in detail.
I have compiled a table that will help you understand in advance what actions you need in a particular situation:
| Symptom | Causes | What to do? |
|---|---|---|
| The phone charges and discharges quickly. | 1. Battery wear. 2. Battery calibration failure. 3. Failure of the electronic part of the device (charge controller). | There is an opinion that from fast charging (available on Samsung) the battery wears out faster. Try not to use this feature unnecessarily. Night charging with low currents will increase the battery life. |
| The smartphone takes a long time to charge and quickly discharges. | Long charging is the norm for high-capacity batteries. Rapid discharge is usually due to heavy applications. | Remember what software you installed on the eve of the problems that arose and remove it. |
| The phone heats up and drains quickly | An overloaded processor causes heat and drains the battery. | Similarly to the second point, you need to identify the culprit program and disable / remove it. Reboot your phone. If these steps did not help, back up the information and reset to factory settings. |
Having studied all the known cases of fast battery discharge of mobile gadgets, I have identified 12 main ones:
Let's take a closer look at each situation (some are separated into different points) and figure out how to solve the problem that has arisen.
Trying to save money, the manufacturer sometimes puts a battery of insufficient capacity for the installed processor and screen in budget devices. Even a healthy battery will drain quickly under these conditions. The only way out is to use portable power banks.
The resource of lithium batteries for mobile devices is about 3 years. After 1.5 years of use, the capacity begins to gradually decrease. By adhering to some rules, you will extend the life of the battery:
Selecting programs that will run in battery saver mode:
If your device does not have Accessibility, please update your operating system or enable Developer Mode. To do this, go to the menu "Settings" - "System" - "About phone" and tap 7 times on the "Build number" item.
Way to save money for Android 8 using an example:
Fans of mobile toys often face the problem of quickly running out of battery. A modern 3D shooter is able to bring the battery to zero in a few hours.
To increase the battery life of your mobile device, change the detail quality settings (water, shadows, light, shaders) to less energy-intensive ones. This will affect the realism of the game, but will allow you to keep the charge longer. Or hang out less in virtual worlds.
Developer errors often lead to various operating system glitches. After updating with poorly optimized firmware, one of the symptoms can be rapid battery drain.
The reason may be unsuccessful firmware, battery wear (I talked about this above), and incorrect calibration.
To automatically calibrate the battery, follow these steps:
The second option is possible with a custom Recovery Menu installed, which has a battery statistics reset (in TWRP, open the "Wipe" section and select "Wipe Battery Stats".
Or go to the menu "Recovery" - "Advanced" - "File Manager". In the data/system folder, delete the batterystats.bin file.
The procedure should help bring the gadget in order.
Always-on mobile Internet (3G, 4G), Bluetooth, NFC, Wi-Fi, GPS, animated (live) wallpapers can discharge a portable gadget much faster than the standard time. Especially if all these modules along with the programs are activated at the same time.
Wi-Fi and GPS can increase power while searching for a signal, so if you are not using them, then keep them turned off.
The screen of a mobile phone is the main energy eater. The higher its brightness, the faster the battery will run out. An acceptable level is 40-50% of the maximum. Vision in this mode is not strained, and the battery of the device "lives" longer. It is convenient to change the brightness through the top curtain. It also helps to conserve battery by using sleep mode, which automatically turns on after 30-60 seconds of inactivity.
At first, I didn't like the "auto-brightness" mode that comes with most phones. But the AMOLED display on my Samsung has a high margin of brightness, over time my eyes got used to it.
The phone battery (also any other devices) is sensitive to high and low temperatures. When it reaches +30°C, my Samsung A5 2017 automatically turns on protection and does not allow any applications to run until the heat drops. Cold conditions are considered to be less than +5°C. It is better to hide the gadget in your pocket or bag at such temperatures. A headset is suitable for calls.
Frequent use of a smartphone in adverse conditions leads to degradation of the battery cells, when it can no longer restore the factory capacity values.
In places of constantly disappearing, bad signal, the phone's battery drains faster. More energy is spent on maintaining an unstable connection. In the suburbs, on a summer cottage or on a wild seashore, there are fewer base stations of cellular operators, and the smartphone tries to amplify the signal for comfortable work, which will certainly affect the battery life.
In a dual-SIM device, it is advisable to temporarily remove the operator's SIM card with a missing tower nearby. A good option is a communication amplifier sold in electronics stores.
Back in 2005, when I got the first phone with a local, now deceased, Akos operator, I could only talk normally while sitting on the windowsill. But then it had little effect on the battery - manufacturers took into account such nuances. For example, Nokia 3310 was not killed and caught the network in the most severe conditions.
Contrary to popular belief, turning off your phone regularly does not help conserve battery life, especially if you do it several times a day. When you start the gadget, the energy consumption is close to the maximum, which reduces all the savings to zero.
Many of us remember well the times when it was necessary to charge a mobile phone every four or five days. Now even flagship smartphones cannot work for such a period. And there is nothing to say about budget ones - they need to be charged every evening. But why is the battery draining quickly? That is what we will talk about in today's article.
To begin with, it should be understood that the battery can run down very quickly immediately after purchasing the device. And it happens that this begins to happen about six months after the start of using a smartphone. All these are completely different cases, and therefore the reasons for the rapid loss of charge may differ.
If the battery of a new device runs out quickly, then the following factors can contribute to this:
You can't argue with these reasons. Of course, you can try to reflash the device by installing a different version of the operating system. But often this does not lead to anything good. As well as nothing to do with the processor. Because of it, during games, the phone heats up and quickly discharges. That's why Qualcomm's powerful chipsets are what people really like - they're much more energy efficient.
If the smartphone began to quickly discharge completely unexpectedly - many months after its purchase, then the reasons for this may be completely different:
These reasons can already be dealt with. Below we will talk about how to achieve an increase in battery life.
If your Android phone runs out of power quickly, try lowering the brightness of the screen backlight. This is done right in the notification panel.
You can also go to " Settings", in the section" Screen". There you can find the item " Adaptive adjustment» - it is recommended to enable the checkbox next to it. In this case, the system will automatically adjust the brightness, focusing on the level of ambient light. Unfortunately, there is no such item in budget devices, since they are often not equipped with a light sensor.
Also, wireless modules consume a lot of battery power. These include Bluetooth, 3G or 4G (LTE), and Wi-Fi. The first two modules can be completely disabled, activating them only as needed. This is done in the same Settings", but already in the tab" Wireless network". Click on the button " More"- so you will be taken to the desired subsection. Well, the button leading to the control Bluetooth, you will see immediately.
In the subsection " More» You can deactivate NFC if your smartphone supports this technology.
Inexpensive devices are equipped with a budget GPS chip, which sometimes does not even have support for the energy-saving A-GPS function. If the navigation part of the smartphone is not particularly important for you, then the GPS operation can also be turned off. For this, in Settings» you should select the item « Location».
Here you should be interested in the option " Mode". Select " By network coordinates". In this case, the smartphone will lose the ability to accurately determine your location, but its GPS chip will stop consuming energy.
You can stop playing games to save battery power. The fact is that they consume energy most actively. And some shareware projects do this even in the background - evidence of this is the various notifications that regularly arrive on the smartphone.
Seriously reduce battery life and regular reboots. Usually they are caused by unstable applications - they should be removed. Also, something could happen with the Android operating system itself - in this case, you can try. But remember that in this case, all user data will be deleted from the device.
Even root access can affect battery life. Try it - it is possible that after that the smartphone will work longer.
It is possible that the problem lies in the software you installed. Some programs have terrible optimization or deliberately consume a lot of resources, which affects energy consumption. For example, the second type includes Facebook And facebook messenger. The client and the messenger get access to almost all the data available on the smartphone - along the way, these applications massively consume battery power, as a result of which it sits down very quickly.
In early versions of the Android operating system, the gluttony of each application remained implicit. But later in Settings» there was a subsection « Battery". Here it is detailed which programs and games are the most voracious.
In the new Samsung smartphones, you can learn about the power consumption of each application in even more detail. All information is on the page of a particular program in " Application manager". Here you can find out how much CPU load the application is creating, as well as other interesting information.
On smartphones with a more recent version of Android, this item may be called "Auto brightness". As a rule, it can be found in the notification panel. There may also be a function "Shades of Grey" which also saves battery power.
If you are using a smartphone with , you can set the screen to black wallpaper to further save battery power. The fact is that such devices do not need backlighting to display black pixels. Therefore, the more black pixels on an OLED display, the more economical battery consumption.
On some smartphones running on a more modern version of Android, there is a special section in the settings "Nutrition and Performance". Click it to view available energy consumption information. With button "Optimize" you can set automatic battery consumption. Below you can find a button to turn on the power saving mode (before the low battery warning appears).
Through activity control, you can set conditions for different applications. For example, prohibit background work, make it inactive, set other restrictions.
As mentioned above, malware is also very battery draining. Fortunately, downloading a virus through Google Play is not as easy as it seems. But other resources are literally teeming with malicious applications. Therefore, it is recommended to prohibit your smartphone or tablet from downloading games from the program from other sources. This is done by going to the " settings" entitled " Safety". Here you should uncheck the box " unknown sources».
Many devices from Samsung have a screen created using Super technology. This alone saves battery life. But if you still sometimes have the question “Why does the phone run out quickly?”, Then you can use a couple of functions related to energy saving technology.
Attention: The following text refers to new Samsung smartphones belonging to the mid-range and higher price segments.
South Korean devices some time ago learned to limit the operation of those applications that the owner uses extremely rarely. To enable this feature, follow the instructions:
Step 1. Go to " Settings».
Step 2. Go to the section " Battery».
Step 3. Scroll down the screen. Here you will find an item related to limiting the power consumption of applications. Click the button in detail».
Step4 . Turn this feature on. Now if any application is not used for three days in a row, it will literally freeze. Its background work will be terminated. This is very relevant for those people who download and install a very large number of programs and games.
In the same section Battery» you can set modes « energy saving" And " Extreme Energy Saving". They are very relevant for devices with a Super AMOLED display. In the first mode, the shades change to darker ones, and the brightness of the screen is also reduced. Along the way, you can limit data transmission via Wi-Fi and turn off location using GPS. Well, the second mode completely turns the device into an analogue, making the screen completely black and removing all auxiliary functions, leaving only the possibility of a call.
Analogues of the modes described above are also present on some smartphones from other manufacturers. But they act on them less effectively, so we seriously do not recommend you to count on a longer battery life.
Each new version of the Android operating system is more and more energy efficient. That's why devices based on Android 6.0 last much longer than technically similar devices that run the old Android 4.2.
There are many apps on Google Play that claim to improve battery life. But in practice they are common optimizers. These utilities remove recently launched programs from RAM. Most often, this affects only the speed of the device, but not the operating time from a single charge. You can get acquainted with the best optimizers for Android in.
Over time, many Android OS users are faced with a problem when the phone charges quickly and discharges just as quickly. This brings a lot of trouble if you need to be constantly in touch, especially away from home.
The manual is suitable for all models and brands (touch and push buttons): iPhone, Alcatel, Asus, Lenovo, Phillips, Prestigio, Sony Xperia, HTC, Samsung, Xiaomi, Umidigi, Leagoo, Dexp, Oppo, Doogie, Huawei, HomTom, etc. d. In this context, it does not matter what software is installed: iOs or Android.
This option most often happens with old batteries that have exhausted their resource. Each battery has its own expiration date, but, as a rule, smartphones last a long time without replacement. That is why problems with charging and discharging the battery are the most popular among gadget owners.
It should be noted right away that some gadgets charge quickly right from the factory. They are technically equipped with this function, and in the box they come with chargers designed for this purpose.
But fast discharge for modern devices is not typical. Experts identify three main reasons why the phone is quickly discharged:
When the phone starts charging for a long time and discharges almost instantly, you must immediately “sound the alarm”, otherwise there is a risk that it will let you down at the most crucial moment, and you will be left without a means of communication for at least a few hours. Battery life is shortened due to:
As soon as you notice problems in the battery charge, you should immediately take the first emergency measures to solve this problem:
IMPORTANT! Sometimes the cause may be a third-party application that has nothing to do with the battery. Try to remember, perhaps the problems started after installing a particular program. Try to remove it and check the battery again.
It is difficult to give an unambiguous answer to this question, since the battery charging time depends on the capacity, optimization of the Android operating system, the availability of Quick Charge technology, and the volt-ampere characteristics of the charger.
Therefore, battery problems are most often diagnosed in comparison with the first experience with a smartphone. Do not forget that over time, the energy efficiency of any battery drops, but only slightly, and in normal cases this has almost no effect on performance. Only the battery life is reduced by a few minutes.
A great way to “support” a smartphone until the battery is replaced is to install a special program designed for this purpose. There are several dozen of them in the Play Market, but we will talk about the top three that effectively prevent problems:
In order for the battery to serve for a long time, it is necessary to adhere to the rules for the effective operation of the device:
In most cases, to solve problems with appliances, the battery just needs to be replaced at a service center. If the device is under warranty, then this, quite possibly, may turn out to be a factory defect, and the replacement will be carried out free of charge.
Before "hacking" a smart to obtain superuser rights and lose warranty service, contact a specialist. One diagnostic is enough to find the cause of a failure or breakdown.
When such a phone falls into my hands, one that, for example, has been discharged for a long time, and it does not charge into any. My sister brought a phone that had been lying empty for over 4 years. I turned on the charge for a day, and it did not charge. Then I decided to test its charge properties. I took out the battery and connected the tester to the charge pins. It should be noted that there are always three contacts, but in reality for a charge there are only two extreme teeth - one plus, the other minus on these contacts should be approximately 3.6 Volts or a little more. If there is no voltage, then the phone is faulty. However, there was voltage on that phone and the battery was faulty.
Lithium batteries are characterized by the fact that they are very afraid of deep discharge and no matter where they are in the phone, tablet or laptop. They can be discharged so that then it is not charged. What can be done about this case? You need an external charger. I usually take any 5 volt charger. If this charger is unnecessary, I cut off its nest, clean the wires and measure which one is plus, which minus, and on the battery I also find out which plus, which minus. On some it is written, on some you can understand, will you ring that there is a case in my phone? The case will naturally be a minus. So, I know what plus what minus on the phone, and I marked them on the wire.
I measure the voltage on the phone battery with a tester. If it is slightly more than 2 volts, this is the critical voltage at which the battery simply cannot physically charge. Then I gently hold the wires with my fingers, connect them to the battery and control the heat of the battery with my fingers, if it starts to get very hot, then I quickly turn it off. But usually this does not happen, it gets a little warm, I charge it for minutes and 3-5 when it does. Why measure with a tester, usually the voltage reaches 3.1 volts. This is a perfectly acceptable voltage.
Now, having inserted the battery into the phone, I scream with joy, because the phone starts to turn on, but it says: “the battery is low,” but this is no longer important. Now it remains to connect the charging, and it starts charging. Thus, I restored a Japanese tablet that fell into some guy, but I just can’t turn it on and won’t charge. A laptop battery, which also lay in the box for a long time and was not charged in any way.
And on phones, I have more than 10 pieces of all sorts of devices lying around, I also restored batteries to see how they work. The spirit of recognition moved me. In fact, in the service center for this purpose there is a special charger with adjustable voltage. By the way, they are sold in stores and who does not mind a couple of thousand rubles can buy it. Charge all batteries from penlight to car. Some chargers do just that.
But in most cases, as they say above, the phone just freezes. Yesterday it worked today it does not charge. So you need to remove the battery from it, wait 20 minutes until all the capacitors in the phone are discharged, and it will not reset everything, even the date. Insert the battery back and try to charge it. In 99% of cases it will charge. What if the battery is non-removable? Realistically, this does not happen. There are no non-removable batteries! All batteries are removable. It's just that some are made in such a way that removing it is rather difficult. Sometimes this requires unscrewing certain screws.
But in fact, if there is a desire, any battery can be removed from the phone case or some tricky laptop. It can also be recharged with an external power source, and it will work. Unless, of course, he's completely ruined.
For a modern phone, the main and decisive criterion is its autonomy, that is, how long the battery can work without recharging. The most terrible event for many is when the phone is discharged so much that it does not respond to the charger. Why is this happening? How to revive the phone battery?
Each battery has a power controller. It is thanks to him that we can see on the screen the percentage of battery charge. The same element determines the need for the device to recharge. When the phone runs out of power, the controller, after urgent requests to replenish energy reserves, enters the battery protection mode from complete depletion.
It is worth noting that the battery is charged through a charger, which has this information and contains a way to revive the phone's battery - to start the current directly. In order for this not to pose a danger to life, there are several simple ways, which are discussed below.
As unexpected as it may sound, leave your device to charge for a day. For some devices, the boost will be one of the pulses received from the charger. Roughly speaking, at some point the battery will "catch" the current and begin to accumulate charge. Don't get mad if your phone reacts to the charger with a dark screen. In this case, there is no need to rush. Other methods should be tried only after this method.
For the second, more complex and time-consuming method, a power supply with a constant voltage of up to 12 volts is required. It is better that the voltage is from five or a little higher (it's safer). You can use the power supply from the router and even the charger from the smartphone itself. As an assistant, a resistor is suitable, which is designed for a power of 0.5 watts and a nominal value of 330 ohms.
As for the voltmeter, this is more of a whim than a necessity. So its presence is by no means necessary, although it is highly desirable.
The connection scheme is simple to the point of primitiveness: we connect the minus of the source to the minus of the battery, and the plus through the resistor to the plus of the battery. Where is the plus, and where is the minus at the source? If you have a charger like a plug from a Wi-Fi power supply, then the plus is the inside of the cylinder, and the minus is the outside. For the USB charging type, you must first do a test with a multimeter. This will allow you to check where is the plus and where is the minus by ringing each channel.
After everything is securely fixed, you need to apply current. If you observe on a voltmeter, then you should wait for the voltage to rise to 3.5 volts - this is about 15 minutes of continuous operation. This is ideal for old-style batteries, but it works for smartphones too. Again, take your time and stay calm. A mistake can cost the life of the battery.
A less time-consuming method, of the phone, is to use a power supply with a controller designed to restore and charge all types of batteries. Such blocks are used when restoring Ni-MH batteries. This device is like Turnigy Accucell 6. How to use it? Just like with cables in the second method.
It is important with this method not to try to fully charge the battery through this device. Why? Over time, the battery wears out, and its volume is significantly reduced. In order not to ruin the battery, charge it through a universal charger up to 3.5 volts, and then through the phone or tablet itself - with a device whose battery we reanimated.
In simplicity, this method can be compared with the first. Unfortunately, it does not work on all types of devices, but it has to be, since it does not oblige you to have additional equipment or skills. This way, how to revive the phone battery at home, looks like this:
Why might it work? As mentioned earlier, the battery needs to be "pushed". Such a sharp current flow can become such an impetus, and the battery will return to normal, starting to accumulate energy.
This method also does not always help, but nevertheless it is very popular. To implement it, you need to take a fully charged battery or a powerful battery and connect it using conductors, observing the polarity. After ten minutes, you need to try to insert the rechargeable battery into the phone and connect the charger.
This method is based on the method used by motorists, giving a "light" battery from another car. And just like in cars, don't let anything get hot!
Another, no less strange way, is freezing. Some who have already conducted similar experiments with the battery of their device claim that they were able not only to “resurrect” it, but also to increase its life. The principle of operation of this method is to deceive the controller, which was mentioned above, because at a reduced temperature, the chemical reactions in the battery slow down significantly.
Before restoring your phone's battery, make sure it's not lithium-ion. This type of battery may not be able to withstand such experiments.
The recovery process itself is as follows. To begin with, a battery discharged below the level is sent to the freezer for a period of no more than half an hour. After that, charge it for a minute. In this case, turning on the phone is strictly prohibited. Next, you need to remove the battery from the device and let it warm up to room temperature on its own. It is impossible to heat and rub the battery at the same time.
As soon as the battery reaches room temperature, it must be put into the device and charged in the usual way. Such charging can last more than a day, in some cases even two.
Before you revive the phone battery, completely discharged, it is worth deciding which of the methods is most effective. All of these recovery methods are good in their own way, but some have no confirmation in their safety, others require special skill and tools.
In fact, the first and fourth methods are not only ways to revive the battery of the phone, but also a real guide for an emergency. Such methods will not harm and will not aggravate the situation of the smartphone.
There is quite a lot of controversy about freezing, as low temperatures are what can cause a battery to swell. Some say it's a way to give a "dying" battery a "painkiller" so that it dies quickly and painlessly.
Even Ni-MH batteries are restored in the second and third ways. But if you do not have access to the necessary equipment and are simply far from electronics, it is better not to risk it and turn to the masters of this business.
Whatever method suits you, the best solution to the problem is to prevent it. Try to make sure that your smartphone does not turn off because the battery is dead in it. Carry a charger kit or external battery with you and recharge the battery when needed. Try to avoid friction, shock and large temperature changes - this greatly reduces the performance of the battery and shortens its life.
