Hello,

I have had my S22 Ultra since I received it from preorder and have recently developed a new issue. It happened once a few weeks ago and again last night. My phone was just over 50% battery life when I went to bed and then it drained to 0% in the night.

I looked at the battery history and from 12am-2am the battery drain looks normal and then from 2am-4am it plummets to 0%. In this time it only registers Google Play using about 17% and the rest is unaccounted for. I also use a battery tracking app that registered the high drain with the screen off without attributing it to anything.

How do I determine what is causing this drain and prevent it in the future if neither record has attributed it to anything. In case it is relevant, I put my phone into sleep mode at night. 

Any help is appreciated,

Thank you,
