Xiaomi mi 11 quality battery replacement ?

[snow1]

Hello friends! I changed my old battery with a new original one. From 3.30-4 hours SOT, now I have like 5-5.30 max of SOT. But I have a problem. When it reaches 20% of battery charge, it discharges like crazy, 30 seconds for 1% of battery, sometimes it just dies under 20%. Did a factory reset, but nothing changed! How can I adress this issue?

Have you let it deplete completely 100% to 0% and charge all the way upto 100% and leave it charging for few hours after reaching 100%

Hmm not sure , my new battery was nice improvement on miui 14 but since going to hyper OS it's gone worse

I'll be upgrading phone soon to OnePlus 13 , I might try custom evolution rom on mi 11 the pixel experience see how it is
