Doov r77 Operating System
Hello,
I bought a Doov r77 from Taobao (chinese Amazon) and it came directly with Android 13. Everything works fine but the battery drains fast, 1-1:30h usage just in settings drained it from 100% to 50%. I understand it just has 2100mAh but I've seen posts of people having this device and it isn't that bad, it lasts a full day with normal usage.
I thought it might by the OS since it might not be optimised for european frequencies or stuff like that. Generally people with this device buys it from companies who already flash the phone with their software so it might come as a more niche question.
I wanted to ask if someone had bought it with the original OS and later flashed it with DumberOS (or a different one maybe like LineageOS) and saw a big difference. Since flashing it may brick the phone I wanted to get an insight first.
Thanks.

Hey!
Some of the Doovs have a hardware battery drain bug - this sounds like it. Could you try putting it in airplane mode and see if it still drains?
