    I have a double whammy situation with my s22 ultra after the android 13 update.

    My battery life has been cut drastically by about 60%. Currently I am losing about 40% of charge in one hour of use. Phone stays warm through the day. Only browsing the web and playing YouTube Music. As you can see with the screenshot the predicted battery life is ridiculously off from reality.

    Also my phone won't charge nearly as fast as before. Regular fast chargers can't even keep up with the phone. It actually discharges while plugged in. I have to use super fast chargers to keep it charged.

    I know the charge rate was reduced for all the chargers (not just excessive phone power use) because I have one of those digital charging cables on one charger that shows the charge rate in watts. It used to show 22 watts on a super fast charger. Now it shows only 9 watts on the same charger. Once in a while I'll see it briefly bump to 15 watts but mostly at 9 and never at 22 where it used to be.

    So I have both a massive battery drain problem in addition to the charge rate being cut drastically. All in all it makes the phone almost unusable. It constantly needs to be plugged in to be used.

    I do not want to factory reset my device as it takes me days to get it set up the way I have it. Is there a way to fix my phone? Any advice is much appreciated.

    Have you tried clearing the cache partition from the phones recovery menu?Turn the phone off and hold the volume down and power button while you turn it back on. If you're outside the US, you need to plug the phone into a PC while you do this.

    I also agree with testing in Safe Mode first -- that way, you can tell if the problem is due to some app you installed vs the system itself. http://www.samsung.com/us/support/an...20the%20screen.

    Thanks all. I tried clearing the cache partition and no improvement. I didn't try safe mode yet but how could I identify and remove a third party app if I determine the battery drain isn't problematic in safe mode? Is there any way to determine if one app is using more power than it should?

    Identifying which 3rd party app is the culprit can be challenging, but what we're trying to do first here is to narrow things down to 3rd party app vs system. If you don't see the rapid battery drain in Safe Mode after an hour, then it's most likely a 3rd party app. Once we've determined that, we can go from there.

    It's also conceivable that a 3rd party could be messing with the charging as well.

    If it's an app causing the drain, GSam Batttery Monitor may help you identify the "bad" app.

    My battery life has also taken a huge dump. Hopefully they release an update soon.

    My phone just chews through the battery without even using it.

    My battery life has not been that great either. It's not been as drastically bad as what the OP has been experiencing, but it was bad enough to prompt me to do a factory reset and start with a fresh install. Just got done sitting everything up, hopefully it will go well.

    I am planning a factory reset today. My battery drains from 100% to 80% in a matter of an hour just sitting on the nightstand

    I've been having the same exact problem as OP, wondering if OP found a fix.

    Welcome to AC!

    Have you tried clearing cache in recovery, sometimes needed after Android updates
