iPhone 16 Pro Battery Draining Quickly

Iphone 16 pro battery seems so poor. I unplugged my phone at 9:15 am and by 4pm it had only 32% with 3hrs of screen time. I did my 0.5gb update hoping it will extend baterry life and upgrade functionality of my iPhone.

How is it possible? Anyone experiencing bad battery life as well?

I had the exact same issue. Drove me insane. Battery was terrible, especially while phone was idle. Talked to Apple and they said to bring it in for inspection. I reset the phone (not factory reset) and nothing. HOWEVER, I tried a factory reset via my MacBook, and voila! The problem is gone. Battery is now amazing! Charged my phone 20 hrs ago and it still has 71% left. So, factory reset via your computer. My guess is when they installed software there was some type of error when downloading directly to the phone in the beginning. Hope this helps!

Hey I just got my iPhone pro 16 yesterday. I unplugged it from full

powrr and it’s down to 75% in 2.5 hours… that will give me 10 of power at this rate! Ridiculous. Can you share how you did the factory reset by computer? I don’t have a Mac so not sure if it would work for me but I would like to try. Does that also then totally reset the phone with none of my setup/downloads etc?

I already have a bunch of functions disabled, i don’t have background app refresh on, i don’t have always on display, i am using wifi, i keep my luminosity pretty low, location is set to while using… and that’s the stats that i got with all these things set. I didn’t see anything improving up until now… so i have no idea if its the phone, if i had too much expectations from it (battery not too drain that fast).

I I hope what you’re saying about the phone still doing all the indexing is true because I just got my phone yesterday afternoon 16 Pro. This morning 8am I had a full charge. It’s not even 2:30pm and I have 17%. This is unacceptable if this is the battery life all the time then I am definitely returning it

It happens after every update and we have seen the same reports with the iOS 17 update as well and they eventually go away. If you still see that same performance after 3 days, then I would recommend taking it back. It is expected to last all day.

It has been 3 days now since I got my iPhone 16 pro and I am blown away by the poor battery life. I believe all the updates and configuring as apple support stated is complete. The phone is no longer running hot. But the battery life is unacceptable. Thinking of returning it. Has this improved for anyone? If yes what did you do ?

Here’s my update. My 16 pro is no longer running hot. That’s a good thing. The battery life is still not the greatest but when I went to choose a photo to upload it said my photo app was still indexing. I have over 56,000.00 photos. A quick search read that indexing does use minimal battery since it’s running in the background unless you have a huge library, which I do then it uses more. I will keep an eye out and see where I am at after one week. If indexing is complete and battery is still draining then I will return it. Hoping I do not have to because I really love the phone. So if you’re like me with lots of photos wait until the indexing is complete. This is day 4 of indexing.

Hi so Apple support called me one alarming issue if you look at the attached photo is my photo usage: I was on photo screen time 3 hours but background was 11 hours. They said the “big new update” may fix the battery drain issue but I didn’t want to loose my 14- day return window. I returned my iPhone 16pro Oct 26 and upgraded to IPhone 16 pro max.
