The battery is still the Achilles heel of Android smartphones today. Despite the obvious progress made in this area, the capacity of accumulators inexorably diminishes over time. In the medium term, this phenomenon risks distorting the estimate of remaining energy. To improve the accuracy of the battery gauge, it is therefore essential to recalibrate the battery. We explain how to do it..
Lithium ion battery
All Android smartphones are now equipped with batteries using Lithium-Ion technology . These offer many advantages. Unlike the old Nickel Cadium accumulators, they do not require any maintenance operation.
For example, there is no longer any need to completely discharge your smartphone to maintain its maximum capacity. The memory effect that affected nickel batteries disappeared completely with lithium. On the contrary, it is recommended never to cross the 5% remaining energy mark as this could have a devastating effect on the life expectancy of your battery..
Inaccurate battery gauge
These noteworthy progress should not obscure the fact that many points still need to be improved, such as the accuracy of the information provided by the battery charge indicator. The accuracy of the gauge varies considerably over the life of your smartphone.
It often happens that the remaining autonomy announced by Android does not reflect reality. Who has never seen their mobile phone go off by itself for no apparent reason, when there was no less than 20% of battery left?
With the phenomenon of wear, the accumulators lose part of their capacity. If you do not fully discharge your phone (up to 5%) at least once a month, Android will not be able to accurately tell you the charge level..
As we all know, this information is crucial to optimize the autonomy of a smartphone or tablet. The fear of going out of steam is far from a myth. Fortunately there is a method to recalibrate your mobile device on the actual capacities of the battery.
How to calibrate the battery of your Android smartphone
The procedure we present to you below is suitable for most phones. However, this may vary depending on the models of Android smartphones. Do not hesitate to consult the instructions for use of your device for more information.
- Charge your smartphone fully (100%)
- Then remove the USB plug from the charger
- Press the Power button to turn off your mobile
- Then connect it to a power outlet
- If the gauge does not show 100%, your phone must be recalibrated
- Leave your phone screen on or start a 3D game to fully discharge your mobile
- After a few hours it will go out by itself
- Then plug it into your charger without turning it back on
- Let it recharge fully up to 100%
Here your battery is now calibrated. It will just be necessary to respect a few simple rules to optimize the autonomy of your Android mobile.
