If it really happens in every ROM then the battery drain is caused by some App you are using.Facing this issue in every ROM I flash.
Flash rr remix. There's a setting to turn on 2g when screen is off. Saves a ton of battery. Also, your network signal seems awful.Any solution for this severe battery drain?
10 percent drain overnight without WiFi and 4g.
ROM: NOS(1june stable build)
I flashed citrus and voila battery drain gone. Thanx a ton.If it really happens in every ROM then the battery drain is caused by some App you are using.
You also got a very bad mobile network signal. Try flashing Citrus CAF or even better xiaomi.eu stable ROM to improve your signal
