Hello there, I recently bought a Xiaomi Mi4 (Mi4W) 3GB, 16GB, Overseas edition. It came with Global Stable MIUI 18.104.22.168 and the battery, with a normal usage (mail, chatting, browsing, no games or movies) behaved just as follows, and it behaves the same with current Global Stable MIUI 22.214.171.124 - Battery drains fast during normal usage, with important drops of 2-10% in minutes. - Battery drains fast during airplane mode, ~15% in 7-8 hours. Additional info: - Balanced mode always. - Screen time different results as for stock battery monitor (58% / ~4:45 hours) and GSM battery monitor (82% / ~13:45 hours) - CPU usage seems OK, with plenty of deep sleep. - No noticeable sucker app. - No heating. - I been suspicious of having a fake phone, but after some tests (cpu-z, activating engineer mode, antutu test ~45,000, battery capacity) it doesn't seems so. I've read many threads and similar issues, but I didn't found a clear solution. Some users claim that with other unofficial roms the problem is gone, but I don't want to renounce to MIUI. Hope we can find a solution for such amazing device. Thanks and regards!
