Thanks for your response bro, I’m already following these tips from your videos.
Mine is a 3-month-old phone I watched your videos regarding the 16.3 updates and after that only I updated. Still, I have 100% battery health but on standby, it was a 2-3% loss of charge in the night to morning time but now it’s like a 10% battery loss.
Please suggest me some other ways, bro.
