battery drain ios 17.2 iphone 15 pro max

I installed iOS 17.2 this morning. I’m not a power user, I don’t play games, I do browse social media quite often. My 15 Pro Max has drained so quickly that I had to charge it for a second time today. I usually end the day with 70%+. I reset my phone completely and charged to 100% earlier. I’m at 54% after 5 hours. I literally watched my phone lose 20% capacity in an hour and I barely touched it. Not a good experience.

I do not have the pro, but my battery is draining very fast after I downloaded the new 17.2 update, I had no battery drainage issues before then. I just googled to find out if anyone else was having this issue I took my phone off the charger it was at 100% less than 10 minutes it was down to 82%. I’m not a gamer and I don’t download. I’m just a very casual browser but I wasn’t even on my phone at all after I took it off the charger and it drained that much.

Using 15 pro max. Till 17.2 update my battery life is insane. Whatever I do I charge my phone in every 1.5 days. I was just mind blown and impressed. Now, dear apple just released 17.2.1 surprised update with no release notes. And guess what my battery is just draining way too fast. So stupid. Apple should give option 1 degree backward to get to the previous version. Bad experience till 2 days. More bugs. I got 80% limit battery but it charged to 85%. I think they messed up something with battery programs.

Same here. I hardly have 2 hours of active screen time (Instagram and TikTok), which are not very heavy tasks. However, it drains the battery pretty fast, much faster than it was on the latest iOS 16.


I have Iphone 14 pro with 100% battery health

Same with my iphone 11 ( battery replaced recently ) and apple watch 7.

It's been terrible and here I though it would be better.


Apple's habit of slowing and bottlenecking older phones is not going to go down well. Hopefully more users share their experience and Apple should be held accountable for these bad practices. How are they not testing these before they are rolled out to the users ?
