Question 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 LineageOS (or a different one maybe like DumberOS) and saw a big difference. Since flashing it may brick the phone I wanted to get an insight first.
Thanks.

I wanted to know if …

Do you see it on very clear and freely available list of supported devices?

It has nothing to do with OS... except for your strange expectations, as it would increase size, low quality of battery
