After the Security Patch Level 1 February 2022 update, my Note 20 seems to drain 10% faster than usual. I cannot go beyond 8 hours of average use. Before the update, I usually charged once a day and that was every morning. Now I have to charge twice a day, before sleep I charge until it's 40% then turn the battery saving mode on. And in the morning I charge until full. Wondering if anyone experiences the same?
Sometimes it doesnt ment to be like UncleR said. It should be your battery.Did you drop your phone a lot of times? You can try to change to a new battery at Samsung Authorised sevice centre.
May be give 1 week time after perform the update. Let the battery optimizer app readjust the app battery usage since monthly update has cleared the cache.
