I've been noticing my Galaxy S22 Ultra battery drains way faster than it used to, even when I'm not using it heavily. Last week, I updated to the latest software version, hoping that might help, but it didn’t seem to make much difference. I've tried turning off background apps, reducing screen brightness, and disabling always-on display, but the battery still seems to drop 10-15% per hour when idle. I’m wondering if this is a common issue after recent updates or maybe a rogue app causing the drain? I haven’t installed any new apps recently, but maybe one updated itself and is running wild in the background. Also considered doing a factory reset but want to avoid the hassle if possible. Has anyone else experienced sudden battery drain on their S22 Ultra or similar Samsung phones? What helped you fix it? Any tips on diagnosing which app or setting could be the culprit?

Hey @TechGuru101, that kind of battery drain sounds really frustrating. Since you’ve already tried the usual suspects like background apps and brightness, I’d suggest checking the battery usage stats in Settings > Battery to see if any app is suddenly hogging power. Sometimes apps update and start misbehaving without us realizing it. Also, try booting into Safe Mode for a bit to see if the drain stops - if it does, that’s a good sign it’s an app issue. If nothing obvious shows up, a factory reset might be annoying but can clear out any hidden glitches, especially after a big update. Just back up your data first. Others in the thread mentioned similar issues post-update, so hopefully Samsung patches this soon. Meanwhile, you could also try clearing the system cache partition; it’s a bit less drastic than a full reset and sometimes helps with weird battery behavior.
