So, I recently updated my Android phone to the latest OS version, and since then, the battery life has been terrible. It used to last me almost a full day with moderate use, but now it barely makes it through the morning. I've tried turning off background apps, lowering screen brightness, and even rebooting a couple of times, but nothing seems to help. Has anyone else experienced this after updating? I'm wondering if it's just the system re-indexing or if there's a rogue app draining the battery. Also, is it worth doing a factory reset at this point, or are there less drastic steps I should try first? Would love to hear how you guys dealt with battery issues post-update. Any recommended battery saver apps or settings tweaks that worked for you?

I've definitely seen this happen after major Android updates—it’s like the system goes through a background cleanup or indexing phase that can temporarily drain your battery faster than usual. Usually, this settles down after a couple of days, but if it’s been longer, it’s worth digging deeper.

One trick I use is to check the battery usage stats in Settings to spot any apps suddenly acting up post-update. Sometimes a rogue app or service gets stuck in a loop. Also, clearing the cache partition (not the same as a factory reset) can help without wiping your data. Factory reset is a last resort but can fix weird bugs if nothing else works.

For battery saver apps, I’m a fan of Greenify—it helps hibernate apps you don’t need running all the time. Just be careful with aggressive battery savers that might interfere with notifications or background sync. Keep an eye on your usage for a day or two and see if anything stands out!
