Don’t worry, the next super-duper iPhone 17 will fix everything wrong with iPhone 16. 😆
Some iPhone 16 and iPhone 16 Pro users have been experiencing excessive and unexplainable battery drain, according to complaints on Reddit, the Apple Support Communities, and the MacRumors forums. While many of the reports are from iPhone 16 users, older iPhones running iOS 18 may also be experiencing battery life issues.

There is a long-running iOS 18 battery life complaint thread on MacRumors that was started while the update was still in beta, but there have been a fresh wave of complaints following iOS 18's launch and the debut of the iPhone 16 models.
Affected iPhone 16 owners have seen significant battery drain even when the iPhone is not in use. From MacRumors reader T1aaj:
From JulianL:
In some cases, much of the battery drain happens in standby mode when the iPhone isn't in use, suggesting a background activity could be causing problems for some users. Using the phone seems to cut the battery drain in these instances.

There are similar complaints about the iPhone 16 models and older iPhones running iOS 18 on Reddit, and while we always see reports of battery life issues when a new version of iOS comes out, there seems to be a definite uptick in the number of people having problems.
From Reddit user Ok-Interest-6561:
On Reddit, one user did an experiment with an iPhone 16 Pro and an iPhone 14 Pro, and claimed to have used both in the same way. The iPhone 16 Pro dropped to 58 percent battery life within 36 hours, while the iPhone 14 Pro was at 85 percent.
Battery drainage issues are difficult to diagnose because iPhone usage habits vary so much from person to person and from day to day. Impacted users have tried turning off ProMotion, disabling the Always On display, turning off background app refresh, removing widgets, turning off cellular, and entirely resetting their iPhones. Some people have seen improvement with some of these methods, but not all have, and the battery life issues persist for many despite troubleshooting.
Some users reported improvement with iOS 18.0.1 and the iOS 18.1 beta, but software updates have not worked for everyone. It is not clear exactly what's going on to impact battery, but it's sounding like there is an underlying bug that Apple will need to fix in a future iOS 18 update.

Camera button is the new Force Touch.My battery is trash. It is so random on how it sometimes is decent and other times just drains like crazy after it heats up. Its honestly been a super rocky start for this phone for me. The camera button is useless and the battery life has been worse than the 15 Pro Max at least for me.
Camera button is the new Force Touch.
No issue with my 16 Pro max got it Sept 20th . I charge it to 80% and use it all day and drain it down to under 10 sometimes. I am finding no excessive drain at all even from 18 to 18.01 . Sucks that others are having this problem but everyone I know that has a new one , isn't having any issues . Keep in mind , I charged my phone last night to 80% took it off charger , when I woke up at 830 am and went to bed at 1230am it still had 75% so 5 percent drain in 8 hrs in idle mode is normal I guess. Hopefully apple address these issues soon.

I did every possible and imaginable actions. Aod,promotion, Siri, background refresh, min brightness, airplane mode, etc and etc. 3 % drained overnight…….Every year. Same inevitable complaints. I find that disabling always on display and closing out all running apps allows my 16PM to maintain its battery life over nite. Otherwise the battery drains about 20%. Even though the phone is literally not in use.
For a week???Oh it’s just indexing
