Does your smartphone behave strangely and the battery drains for no apparent reason?
Finding the source of the problem is not always that easy. We have tried to identify the causes that can lead your battery to run out in a flash and find a solution for you!
Analyze the problem in a simple way
The first thing to think about is this: one of the most common causes of increased energy consumption is an unsuccessful system upgrade.
Sometimes it happens that the first release of a new Android version may have some small unresolved problem (that’s why many users wait some time before updating) and among the various problems that can occur the battery leak is among the most common.
As you know, some applications and services continue to run in the background and sometimes updates can create disturbances at this level. Applications that restart continuously, which are never closed or otherwise.
In other words, if you have recently updated your smartphone, look online among the various forums on the internet if someone has the same problem and expect an official solution or not.
If you can not wait for the manufacturer to release a fix, install the source ROM again.
Find the problem
On all your Android smartphones there is a section dedicated to information on the use of the battery, organized in order of consumption.
This means that at a glance you will be able to recognize the cause of your problem. All you need to do is go to Settings> Battery, any Android version you have installed on your device.
If this section does not seem too detailed do not worry: you can install an external application that will provide you with additional information.
There are several, I personally use GSam Battery Monitor that does a good job. Install the app and let it work a few days so it can have some statistics to show you.
Your screen is a battery eater
It is usually the screen that consumes most of the energy from your battery. Normally it should not exceed 15% but may have a higher percentage based on the use of the smartphone.
Obviously, depending on the technology of the screen and the resolution of the same consumption can vary greatly.
Simply reduce the brightness of your screen. Most manufacturers also offer an automatic mode, allowing the screen to adapt to environmental conditions so as not to waste energy, which can guarantee you a few tens of minutes of extra battery life during the day.
Your battery no longer holds pace
Sometimes it is not necessary to blame an app or system: it could simply be the battery that you download. If the smartphone is not exactly new and shiny, it is a common problem.
The battery is designed to withstand a well-defined number of charging cycles when you reach this level the performance of your battery could decrease quickly and drastically.
If the battery of your smartphone is removable, replace it with a new one. If this is not the case, try to contact a service center to check if you can still have it replaced by a specialist. Alternatively, you can try recalibrating your battery.
If your battery does not seem to recharge anymore, the problem could be given by the charger. It seems stupid, but it happens more often than you imagine!
It could also be simply the faulty USB cable, in this case you need to take it with your smartphone.
Try charging your smartphone with another charger (from another smartphone, a colleague or a friend). Check if it is enough to replace the cable otherwise replace the entire charger.
You could save a lot of money by doing this easy test. If your smartphone still does not load properly, take a look at our dedicated guide.
An application behaves strangely
Sometimes, usually after an update, some application may lose its head, remain active and consume the entire battery of the smartphone for no reason.
Going into the battery settings (as explained at the beginning of the article) you will find this application in the list of the most energivore.
At the moment the best solution is simply to stop the crazy application. In the list of the apps that consume the most, select it and then click on Finish to close it.
If the application were to restart itself and resume sucking precious charge from your battery, the advice is to uninstall it waiting for a subsequent update. You can also follow the guide below to try to see if the problem resolves.
“Android system” took half of your battery?
In the Battery section of the settings, you may see a process called the Android System responsible for the inexorable decline in the percentage of your battery.
Normally this process should take no more than 3-4% of your total consumption.
If the percentage is much higher (20% or higher) then you have a problem. This usually happens after a failed system upgrades correctly and means that the operating system is requesting more resources than expected.
The best solution is usually the most radical. Try to reset the factory data to reset the smartphone to the factory state, but not before making a good backup!
If this is not enough, you could try reinstalling the previous version of the original operating system.
Google Play Services takes too many liberties
Google Play Services is an integral part of the Android system and any Android device with Google App. In short, it is what allows you to sync your Google account, access the Play Store and allows you to take advantage of hidden features like Nearby.
Sometimes an incorrect update of Google Play Services can create serious problems with your remaining charge.
One of the best solutions is to uninstall Google Play services updates. It will then be updated automatically again without you noticing it.
Check the network coverage
You got it right, the blame for the battery of your smartphone that dries up quickly could be your operator! Check the level of network coverage and check that the smartphone is not continuously looking for a band to hook up to work.
It is not just the absence of coverage to force your smartphone to make an abnormal number of network scans but also a fluctuating coverage.
For example, if you are in a border area between an antenna with 3G coverage (or HSPA) and one with 4G coverage is not enough, the smartphone may continue to switch from one band to another consuming a considerable amount of energy.
You will notice this because the letters displayed on the signal bar will continue to change between H and 4G (in the case I mentioned) continuously. The same thing could happen between the EDGE (E) and 3G coverage.
There are some solutions that could improve the thing. If the problem involves the 4G band, disable it by going to Settings> Mobile> Preferred network type and select 3G. Alternatively, connect to a WIFI network so that the smartphone does not try to connect to the fastest data network.
