iPhone 16 pro battery draining fast

It feels like the 16 pro drains battery like crazy. Mine has gone from 95% to 81% in 38 minutes of light use and some picture taking. Phone also gets really hot when using the camera!


Anyone else experiencing this?

iPhone 16 Pro, iOS 18

I got my phone on Monday 30th September (delivered at nearly 9pm) and it took me until the following day to transfer everything from my 14 Pro Max, so I didn't start using it properly until Tuesday 1st October. For 2 days, I experienced this issue (excessive battery drain) and I became particularly annoyed because my phone was seemingly permanently attached to a charger and the battery percentage wasn't going up. As of last night I was considering sending it back as other posts on here suggested that Apple support was reporting no issues with the phones even though almost everyone was experiencing the same fault.


I did notice that there is a software update available - and although it is just 18.0 by all accounts this update is just for new iPhone 16's (all variances). It says it's a security update but once installed, my battery life is significantly better - to the extent that at nearly 11.30am, it's at 91% and I've used it for work calls; listening to an audio book for 30 minutes and playing some games since 6.30am when I took it off a normal overnight charge.


Maybe it was the update or maybe something else (although I didn't do or change anything else in my normal phone usage/routine) but the battery drain issue seems to have been resolved.

I bought a phone that was advertised to have more battery life than the older iPhones. That is currently not the case, so I patiently wait for the iOS upgrade that would possibly fix it.

Facebook, instagram etc is not even installed, as discussed before. I have reported this behavior to Apple and awaiting the fix.

I bought an iPhone 16 Pro also, and its battery life is fabulous! far better than any iPhone I have ever owned. I charge overnight, every night, with automatic backup and Optimized Battery Charging enabled. By the end of the day on most days it is still above 60%. Sometimes, with heavy use, it is down to 4%.

Great to hear you are more lucky than us others, hopefully there is a fix for us soon.

Well, about 500 million users are luckier than you. What does that tell you? And, as I already said, there will never be a fix for something that isn’t broken. If you can’t accept the fact that this is a problem with YOUR PHONE you will never resolve it. Here is some troubleshooting guidance that you might have missed when you read the 15 pages of the thread you added to→The last update killed my battery! - Apple Community

Battery usage bugs can affect more than 1 model or one year’s models. There are small numbers of iPhone 13, 14 and 15 users still reporting abnormal battery consumption. However, compared to sales numbers for those models, it adds up to easily over 500 million users.


There are still multiple avenues to pursue, but without your participation, it’s pointless and impossible to move forward towards a solution, which might be iOS 26.
