Dozens of users have reported that after updating to Android 10 the phone shuts down when the battery percentage has not yet reached 1% or 0%. The only solution to this problem is to calibrate the battery again. The process to follow is as follows:
- Discharge the mobile battery until it shuts down.
- With the mobile off, charge the battery to 100% without accessing the system.
- Once the battery has reached 100%, wait a couple of hours without unplugging the phone from the power.
After doing this, the battery should have been calibrated correctly. Otherwise we can repeat this procedure as many times as necessary.
