The title says it all I am getting awful SOT on my MI A2, around 2 hours. I do not think it is a faulty battery since I have been monitoring it. I have the screen brightness on 10-20%, notifications turned off, GPS turned off. I included some pictures of my battery health and SOT.
It’s been proven that the cause of this problem is a certain fingerprint reader. It made the CPU run 100% all the time which obviously ruined battery life aswell. Turning the fp reader off solves the problem however we are waiting for an update from Xiaomi so that we can use the fingerprint reader too. This is really a shame. Please refer to the topic i provided above for further information about this issue.
