It didn't take long to use it. After 400 cycles, the battery life was only 3470 mAh, which dropped to 79% of the new battery.
The key is whether to charge the battery every day, even if the charge exceeds 90% to 100%, it is still charged. Charge 7 or 8 times a day, one month 100 charging cycle.
Suggestion: Mix4 must use less than 20%, and then fill it up. Do not charge at any time. This fast charge of Xiaomi is not a special fast charge chip behind. If you want to use fast charge frequently, you should go to Xiaomi Repair 199 and change the battery every six months.
