You leave your mobile charging with the hope that after a few minutes or hours (depending on whether it has a fast charge or not) it will be at 100%. You look at it after that time and, surprise, only charged to 80%. And you may not disconnect it from the charger and still not go above that percentage.
This situation could be an indication that the charger or battery is defective. That or it’s time to calibrate the mobile battery. However, that it is fair in that percentage is usually always for a single reason and that is not bad: prolong the battery health of the device. And it has a remedy.
Why some manufacturers limit charging to 80%
In the same way that Apple implements an optimized load up to 80% in the iPhone, we also find some Android manufacturers offering this upload by default. An example of this is OnePlus.
And this 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 how they are produced, counting on the fact that a complete cycle occurs when the battery is recharged from 0% to 100%. However, if the mobile is charged in smaller sections, it will take longer to complete that 100% and therefore consume a cycle.
Thus, despite the fact that the battery always tends to deteriorate, It is not the same to consume a charging cycle daily than to consume it every 2 or 3 days. And in view of this, the battery optimization of some manufacturers is born.
It should be noted that in most cases, automatic learning systems so that the mobile learns from your habits. That is, it “knows” when it is better to charge up to 100%.
A 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 just the right time so that when you wake up it will be at 100%. returning to it when it considers base
The downside of load optimization and how to turn it off
Without leaving aside the interesting thing about this charging option, it is essential for us to also count the negative part. And the best example is found in the last paragraph of the previous section. And it is that it may this system does not usually deal with exceptional cases And if for some reason you need to have the mobile available earlier than usual, you will find yourself with 20% left to charge.
Optimized charging options (or “smart charging”)
Luckily, there is a remedy for it that goes through disable this feature. Although it depends on the Android customization layer that your device has, it is generally found within the device’s battery settings. There an option will appear under the name “charge optimization” “optimized charge” or similar (not to be confused with “battery optimization”).
Other ways this option appears It is in relation to what is called “smart charging”. See the Google Pixel as an example. In Xiaomi it exists as “optimized charging”, although it has also come to be seen as an option called “charging speed”, which can be activated to prioritize speed over quality, thus preventing it from stopping at 80 %.
