💬 Battery draining twice as fast since the update last week

I updated my phone software last week and the battery has been draining almost twice as fast. Before this, a normal day of browsing, messaging and a bit of Instagram left me with some battery by evening. Now I'm at 60% by early afternoon, doing the exact same things as before. That's too big a change to blame on the battery just getting old all of a sudden. I checked battery health in settings and it still looks fine, nothing that explains this. So my guess is the update. Maybe some background process or setting got reset and is working harder now. I haven't done a factory reset because that feels like using a hammer on a screw. I read somewhere that phones sort themselves out after an update, once they finish sorting things in the background. It's been 6 days though. If that's what it is, it's taking its time. My sister says I should just go and buy a new battery. I don't want to spend money before I know. The phone isn't hot and it doesn't lag. It just dies faster, every single day. I also charge it overnight, in case that matters, but that part hasn't changed from before. If this carries on another week, I'll probably try the reset just to rule it out. Is this happening to anyone else after the same update? Or is it just my phone? If there's a particular setting that's known to cause it, tell me, it'll save a lot of trial and error. I'll check the battery usage list tonight and post what shows up at the top.

Before you spend money on a new battery, rule out the software first. My phone did this after an update, and it turned out to be one social app running in the background.

Same thing happened on my phone. In my case it turned out to be a rogue app running in the background non-stop after the update. Try rebooting once and also check if any app got auto-updated around the same time, that fixed it for me instead of it being the OS update itself. Force stopping suspicious apps one at a time and monitoring battery drain over a couple hours each can help narrow down the actual culprit if a simple reboot doesn't resolve it.

This happened to me too after my last update. Usually it settles down after a day or two once the phone finishes re-indexing everything in the background. If it does not improve, check your battery usage list in settings and see if one particular app is suddenly using way more battery than before, that is usually the real culprit, not the update itself. Worth also checking if any app permissions got reset during the update, sometimes location or background refresh gets turned back on for an app that previously had it disabled.
