Zenfone Max Pro M1 battery drain issue in idle state
For these past couple of weeks, I am facing a sudden drop in battery in the idle state in my Zenfone Max Pro M1. I am running Android 9, with the latest security update as provided by Asus.
I switch off my phone before going to sleep (12:00am) with the battery % at around 68-70, and when I wake up at around 9:00am, there is not enough battery to even switch the phone ON.
Surprisingly this issue was not there before around say 3 weeks or so. I have not installed any new apps or changed anything in the settings. The battery drop has been a bit more with normal usage as well lately. My phone is around 3 years old.
Please suggest whether it is due to a faulty battery or any software issue. I will update my post with a detailed battery stat image and also after calibrating my battery. But, for now can anyone please suggest a solution?
Thanks for any kind of help/advice you can provide.
