I have problem with the battery after updating to android 12. The battery drains very fast. However, I also have a problem with super fast charging - it is not super fast anymore. I have 40% of the battery, connect it to the charger and it shows that it takes 45 minutes to fully charge. After 50 minutes, I check, and there 67% and 25 minutes until fully charged. After another 30 minutes, the battery is 90% charged. My S20 ultra is slower overall, discharges faster and charges much slower.
I did cache partition. Didnt help at all.

Hey,
Its not the problem of the apps. I turned off phone, had 15% of battery and then connected to charger. After 1hr when I suppost to have almost fully charged phone I had 60%. Battery draining is so fast that from 90% of battery after 14hr phone have 27%. But in that time I didnt touch phone for 7-8hr. Rest of the time is normal using, some game for few minutes, discord, few phones. Its middle of the day and I need recharg it again.

Same problem I am facing I did update on Jan 24 since then superfast charging is not working same as you mention. Another issue If battery drain completely i.e zero percent charge it took hours to initialize start charging.
