It is summer, I get home with a remaining 20% battery and the phone quite hot. I stop to see some videos in Tiktok and … I appreciate how the battery jumps directly from that 20% to 16%. What noses have just passed?
Bulk. Your mobile has an internal microcontroller that uses estimation algorithms based on different variables.
- Voltage
- Temperature
- Current
- Load cycles
As the battery is degrading, the system is losing precision: errors in calculations (something especially simple if we only make partial load cycles) accumulate, the loss of battery capacity is not exactly estimated, and this is ended up translating into reading errors that directly affect the most visible point: the percentage indicated by the phone.
How to know that if my battery is not well calibrated. It is quite easy to know if your mobile has or not the barefoot battery, since its behavior will be quite erratic.
- It goes out before reaching 0%, in upper percentages.
- There are notable battery jumps, more than 1%, both loading and downloading.
- The device never marks 100% or 1%.
That a mobile has the barefoot battery does not translate into a malfunction in it: the error focuses on the visible reading that the user perceives, not on the battery performance itself.
Why summer affects bruise. Telephone batteries have a great enemy: heat. There is no time of the year in which they suffer greater wear and are more likely to barefoot, precisely because of the acceleration of this damage they suffer.
If we do not remedy it, it will be practically inevitable that we suffer sudden turns off for ignoring the exact battery percentage, and that the mobile stops to load efficiently when reaching certain percentages (fast from 20%, slow from 80%).
How to calibrate a battery. Calibrating the battery is nothing more than the process to help the software to get precise readings about the real battery capacity. We seek to learn new vacuum points (0%) and full (100%), so the process is something drastic.
- Load the phone to the fullest and leave it, at least, a couple more hours loading.
- Download the phone completely and leave it a few hours without lighting. By battery protection, there is some reserve capacity after that 0% that is not lost until a few hours.
- Load the phone up to 100%, and leave it an additional time until the phone reaches the maximum load point.
Avoid using applications that promise this purpose: none works. The only way to force calibration is to perform this process manually.
Is it advisable to calibrate the battery? Evidence about calibrating the battery is still limited. There are those who aim to do them every three months, but if we do not observe anomalous behavior, stress the battery at this level may not be recommended. Calibration is necessary when readings are wrong and end up translating into a real problem to estimate how much battery we have left.
The manufacturers are in full war to achieve batteries that endure many more cycles until it goes down to 80%, under which the industry considers it necessary to replace it.
