I think you have not yet forgotten that at the end of 2017 Apple the old ones iPhone were caught secretly slowing down. At first, Cupertino kept silent, and then explained that this was done in order to ensure the stable operation of smartphones with worn-out batteries. Technically it was, since the slowdown did not affect vehicles whose batteries showed no signs of wear. However, the court was not convinced, and Apple was ordered to pay compensation to the victims in the total amount of about $ 500 million. Android – smartphones, of course, do not suffer from the same problem as iPhone, but you can still check the wear of their batteries.
Is your smartphone running out of battery quickly? Most likely, his battery is already worn out.
There are tons of apps for Android that measure battery wear, but AccuBattery is considered the best. In general, this is a fairly versatile tool that destroys myths about batteries and gives advice on proper use, thereby contributing to an increase in battery life.
How to tell if the battery is worn out
Before you can check how worn out your smartphone's battery is, you have to calibrate the app. That is, it is not enough just to install it on the device, you need to use it for some time. This will allow the application to analyze many different metrics, from actual battery capacity to discharge rate, to provide a report. Two weeks will be enough, especially since all measurements are made in passive mode and you will not have to do anything manually.
- Download AccuBattery from Google Play;
- Launch the application and go to the 'Charging' tab;
Without the requested privileges, the application will not be able to analyze the battery performance
- Allow the application to analyze the operation of the device;
- Charge your smartphone as you run out and watch how the wear schedule changes in the Health tab.
In general, what is battery wear? Deterioration is the loss of a part of its capacity by a battery, due to which it gradually loses its ability to store energy. Wear is not a quick thing, because it occurs after several months, and maybe even years of use, and is relative, since it manifests itself in everyone at different times. However, there are wear rates that can be considered normal. For example, 10% per year. That is, if during a year of use the battery has lost 10% of its capacity, this is, generally speaking, normal.
When to change your smartphone battery
You can track the degree of wear in the section 'Health'
But wear of 20% and residual capacity of 80% are already considered quite serious. As a rule, the battery comes to this figure in the second year of use or after its expiration. That is, after that, it is better to replace the battery, because, firstly, it starts to hold charging worse, and, secondly, it becomes prone to spontaneous reboots and shutdowns. It was from them Apple that I tried to rid my smartphones at one time, cutting down on the performance of the processor, the voltage surges of which the worn-out battery simply could not withstand.
How to properly charge your smartphone
Charge the battery up to 80% and this will greatly delay wear
Can battery wear be delayed? Of course you can, and AccuBattery can help with this. The developers who created their application, based on years of research, came to the conclusion that charging up to 80 results in 0.26 wear cycles instead of 1 cycle, which leads to charging up to 100%. This extends battery life by 211%, which is pretty good. So turn on the charging alerts up to 80% and don't let your smartphone charge for longer. To do this, simply go to the 'Charging' section and drag the blue slider to the 80% position.
You might think that this is pointless, but it is not. For example, Tesla vehicles use a similar charging technique. According to Elon Musk, it allows you to extend the battery life. Therefore, the application for driving a car even has a special add-on that allows you to limit the supply of current when the battery reaches 80% charge. I think this is a fairly strong argument in favor of starting to apply this technique. In the end, it will definitely not harm you or your smartphone battery.
