You leave your mobile on charge with the hope that after a few minutes or a few hours (depending on whether it has fast charging or not) it will be at 100%. You look at it after that moment and, surprise, only billed at 80%. And you cannot disconnect it from the charger and not exceed this percentage.
This situation may indicate that the charger or battery is faulty. That or it’s time to calibrate the mobile battery. However, that it’s right in that percentage is usually always for one reason and that’s not bad: extend the battery life of the device. And he has a cure.
Why some manufacturers limit charging to 80%
In the same way that Apple implements optimized charging up to 80% in the iPhone, we also find some Android manufacturers offer this download by default. An example of this is OnePlus.
And it is simply because charging the mobile up to 100% is not good for the battery. Or not always. This has its origin in the load cycles and the way they are produced, counting on the fact that a full cycle occurs when the battery is recharged from 0% to 100%. However, if the mobile is loaded in smaller sections, it will take longer to complete this 100% and therefore consume a cycle.
So, despite the fact that the battery always tends to deteriorate, Consuming a load cycle daily is not the same as consuming it every 2 or 3 days. And with this in mind, the battery optimization of some manufacturers was born.
It should be noted that in most cases, machine learning systems so that the mobile learns from your habits. That is, it “knows” when it is best to charge up to 100%.
And example of this learning It is that if you usually charge it at night, the device will detect it and stop supplying power when it reaches 80%. Then it will resume charging at the right time so that when you wake up it is at 100%. come back to it when he considers the base
The Downside of Load Optimization and How to Turn It Off
Without leaving aside the interest of this charging option, it is essential for us to also count the negative part. And the best example is in the last paragraph of the previous section. And it is that he can this system does not generally deal with exceptional cases And if for some reason you need to have the mobile available sooner than usual, you’ll find that you have 20% left to charge.
Optimized charging options (or “smart charging”)
Fortunately, there is a remedy that goes through disable this feature. Although it depends on what layer of Android customization your device has, it is usually found in the battery settings of the device. There, an option will appear called “charging optimization” “optimized charging” or similar (not to be confused with “battery optimization”).
Other ways to display this option This is in relation to what is called “intelligent charging”. See the Google Pixel as an example. At Xiaomi it exists as “optimized charging”, although it is also considered an option called “charging speed”, which can be activated to prioritize speed over quality, preventing it thus stopping at 80%.
