Hii I'm experiencing faster battery drain for my Samsung galaxy m51. I had bought the phone in April 2021. Much used apps are phone and YouTube and some social networking apps, but not gaming. So can anyone tell me what's wrong I mean battery tests and everything go normal even apps restricted in background, using dark theme. But can it be due to current update the phone is having since there is no phone update since July. And also airplane mode takes time to start when pressed.
