How often did it happen that the smartphone worked, but turned off when the remaining charge was 30-40 percent or more? If you are familiar with this, or, for example, you have encountered the problem of decreasing the battery capacity, you should go through one fairly simple procedure, which will not take very much time, but, most likely, will solve almost all problems, if they are not pathological. Of course, you can go to the service and just replace the battery, but it is better to leave this option as a last resort and first try to resolve the issue at the system level. In this article I will explain why you need to calibrate the battery and in what situation it can be of real benefit.
Let's see how and why you need to calibrate your smartphone battery.
When do I need to calibrate my battery to Android?
First of all, you need to understand how old your smartphone is. If this is a veteran from the past who still found the times when 32 GB of memory in a smartphone could be bragged, you should not expect miracles and the method below is not for you. If you bought it a year ago or even less, you have a direct road to calibration in the following cases.
The main signal that it is time to do something with the battery will be the shutdown of the device at values of 20-30 percent of the charge. Sometimes this value can go up to 50 percent or more. Of course, this is not normal and the smartphone should not work this way. Even in the cold, this is not considered the norm, although many think differently and put up with it. In the cold, this is, so to speak, permissible, but definitely not the norm.
Another sign that a battery calibration is needed is an incorrect display of the charge. For example, a fully charged smartphone might display 90 percent. There are times when 100 percent of the charge is displayed, but literally within a few minutes the level drops by 10-15 percent and then it works normally. Many users in our Telegram chat complain about cases when the charge fluctuates in the range of 80-100 percent when the smartphone is disconnected from charging. In this case, the value not only decreases, but can also increase.
In all these cases, you can safely calibrate the battery – it certainly won't be worse. You can look for a good application for this, but, as practice shows, they all have their drawbacks and you should not expect much from them. It's easier to use the “manual” method. Moreover, this method is recommended by Google itself.
Charging your smartphone correctly is almost a science
How do I calibrate my smartphone battery to Android?
There are ways to fully discharge (until it turns off itself) and then fully charge the smartphone to the maximum value. This method is not bad and may work, but it is better to pay attention to the method that Google experts give on the support forums.
First, connect the charger to your smartphone and charge. It is important that the charge is full, and even after reaching 100 percent, it will still be connected to power for at least eight hours. You cannot disconnect the cable. Therefore, it is easiest to turn on such a charge at night.
After that, you need to disconnect the charger and turn off the smartphone. After it turns off, reconnect the charging cable to it and continue charging for at least an hour.
Disconnect charging and if the smartphone does not turn on automatically, turn it on. After that, let it lie down for a while in the on state with the unlocked screen.
After 10-15 minutes, turn it off again and connect it to the charger for another hour in the off state. After that, the smartphone can be turned on and used as usual.
As mentioned above, this method should solve the problem of battery operation or displaying its status, if it is software. In the event that this does not help, you have a direct road to repair (just choose a quality service) or to the manufacturer to resolve the issue under warranty.
Like a sports car without gasoline, a modern smartphone, with all its quality, power and versatility, is simply nothing without a normal battery. If he does not work as he should, and there is no certainty that at 50 percent he will work as much as he worked before, this is not life, but torment. Big battery for you!
