What should I do if the battery health in Redmi drops to normal?

Redmi battery health drops to normal as follows:

1, extending the battery life of mobile phones. Turn on the functions of dynamic performance adjustment and automatic screen brightness level during daily use, turn off the mobile data connection when surfing the Internet with WiFi, and use headphones instead of external playback when playing videos and games.

2. Replace the new mobile phone battery. When the battery health of a mobile phone drops to a certain extent, the battery life of the mobile phone will obviously decline. Replace the new battery directly to ensure a good mobile phone experience. Need to go to the official after-sales center to replace the battery.
