Frequest Sudden Shutdown

[postearth]

My "Xperia Z5 Compact" (Android Ver. 7.0) has shut down frequently for around last 10 days. Even if the battery is still 30%, the phone suddenly shuts down and shows "low battery" indicator. Whenever shutting down, I immediately charge the power to the phone, then it recovers with indicating the original battery power (e.g. 30%).

I am feeling very stressful and irritated. If anyone has the same experiance and knows how to solve the issue, I woud like to know and request you to share & reply.

* I am using the phone in India. MNO is Airtel. I think the environment related to mobile is very bad in India and Airtel SIM(4G) consumes lot of battery power unneccesarily. In Japan or other country, it is not like that.

Well, I'm in PR and my Z5 battery isn't lasting that much either since the last update. Anyways, have you checked on Settings } Battery } Show battery usage?

That way you'll see if a specific app is draining your battery.

Thank you for your reply.

Yes I have checked. Idling, Android OS, Andoroid System and Cell Standby consume buttery.

I expect further update which improves battery...
