Apple needs to fix this.

  1. Happens with all new iOS updated or phones and then they eventually get better.

  6. Hahaha....its main competitior already has satellite phone function, and is producing world's first trifold phone. IPhone is still trying to get its battery right. Hahahaha.

  7. I would love to know why I am expected to pay nearly £200.00 more for the same apple phone compared to America. Vat and usa tax is 6.5% difference plus the ukl currency is stronger than the USA dollar

  16. iPhone 16 here, no issues with battery life. Still at least 2-3 days with light to moderate use. Like always.

    2. Good to hear that Dude, and that you've managed by that post to negate everyone elses experience. I'm sure others will come on here to specifically support your experience with their own phones and by then the evidence of three or four posts of no problems will be so overwhelming and we can all move on.

  17. I have the 18.1 beta on my 16PM, battery life is odd. Some days it's great, others (like today) not so great. It's currently at 43%, been off its charger since about 7:00am, moderate use and no phone calls. Past experience with phones, it should be at around 60-65% right now considering the phone is just short of a month old.

    1. As always there’s rogue code or RAM leaks that happen the first 6 months of these releases which is why the yearly update cycle needs to stop. The more crap they pile on the more complex it gets and the harder it is to track and squash bugs. What they should do is do smaller updates going forward. Update apps with new features slowly instead of doing the massive yearly dump. Plus it would be better for consumers to not have to wait months or years for them to fix the dumbest things.

      Think of the Apple Intelligence rollout. It’s gonna be a drip of new stuff over 6month. Apply that logic to the rest of the OS.

    2. I'm seeing a similar thing on my 16PM. I was coming from a 15PM with 18.1 beta installed - after my 15PM first got the OS upgrade, its battery drain was a bit more - as expected, since I assumed AI features needed to build their language models and such....but then settled to the usual 50% left at the end of a day. Then I got the 16PM and it never did settle down (my wife who did the same upgrade, complained about battery drain as well, so it's not isolated). It often gets down into the 20-30% range, but some days it's in the 50% range. All in all very disappointing as the advertised battery life (supposedly 10%?) was pretty much the only "feature" we cared for when upgrading.

      BTW, I was one of the early contributors on that Apple support thread referenced above. I wonder if Apple will do anything? I wonder even more if any publications have done real-life battery tests - rather than just running videos until the battery is dead?

  18. We see this every year. Give the OS a month or two to settle.

    ReplyDelete
  19. On 18.1, my battery life is excellent.
    Maybe others' phones are scanning their photo library. I updated to 18.0 (beta) long ago.

    ReplyDelete
  20. Apple really needs to take a year, pause the new products, new features, and give us a good ole fashioned Snow Leopard and iOS 12 update. Focus on fixes.

    1. How great would that be? But it’s not shiny, sexy and new and does nothing for shareholder value. If those criteria aren’t met Apple isn’t interested

  21. Battery is great on 18.1. Wonder if this is only some units.

    ReplyDelete
  22. iPhone 16 Pro Max here and there is a noticeable battery drain on these devices.

    ReplyDelete
  23. I had the best battery life on the version of 18.0 that shipped with my 16PM. Updating to the public release of 18.0 saw a significant battery decrease; 18.0.1 isn’t any better. So whatever changed from pre-release 18.0 to now is what is causing my issues.

    ReplyDelete
  24. excessive battery drain could be attributed to a handful of apps too. adding a new feature can result suboptimal operation, and suddenly the app ends up consuming more. but if you don't use that app, or use it with different settings enabled, and your device will not experience excessive drain. energy efficient programming is absolutely important.
    it's not always the OS, but certainly there's always the possibility.

    ReplyDelete
  25. Waiting to see what happens to battery life when full-fledged Apple Intelligence rolls out. Suspect the figures that all the reviewers swooned over when the 16s and 16 Pros were launched may shrink significantly.

    ReplyDelete
  26. Not one to usually have issues, but I swear my battery life has not been as good last month or so either. Maybe is software. Battery still at 89%

    ReplyDelete
  27. Every year...

    I have held off updating my iPhone 15 for just this reason. Battery life on iOS 17 is great - I have a charge limit set to 80% and I only really every top up my phone in the car (normally two 30 minute journeys per day). If I'm streaming a lot of music, I may also top up when working from home at my desk. Other than this, no overnight chatging is needed and I still rarely get below 20%. I use my phone a lot, but mostly for browsing, music & podcasts - little video or gaming.

    I'll probably bite at iOS 18.1 and hope that the bug has been squashed.

  28. Oh it’s just indexing

  29. No problem with battery life with my 16 Pro.

    ReplyDelete
  30. had the same problem on 18, went to 18.1 beta, resolved

    ReplyDelete
  31. users of new Apple products complaining? I'm so shocked

    ReplyDelete
  32. I still have 45% on my phone so I think I can at least get through this co

    ReplyDelete
  33. I’m sure a fix is incoming. This far haven’t noticed much on my 16PM. My 14Pro is awful tho.

    ReplyDelete
  34. Yeah, battery life is never satisfying with every phone release. What we need are breakthroughs in battery technology. Would love to have a 1 week long worth of battery life on an iPhone.

    ReplyDelete
  35. Nearly every upgrade I’ve noticed that third-party apps are largely to blame. Whenever I see the battery drain, I launch Omnistat to check if the processor is running above 5% for both User and System. If it is, I start killing third-party apps one by one until the processor drops to 5%. Inevitably, it’s TikTok, YouTube, X, Instagram, and so on. After killing these apps, both the processor and battery are better.

    1. Would turning OFF background app refresh rectify battery drain ?

  36. 16PM here, mine use 50% of the battery every day with 6-7 hours of screen activity.

  37. Early major iOS versions are unstable. Like clockwork every year.

    ReplyDelete
  38. Yeah mine doesn't have this problem. But the camera button is kind of wack.

    ReplyDelete
  39. Same old complaint with every new iPhone release. 🙄

    ReplyDelete
  40. Doesn't this happen with each new iOS, each and every year? Many of us, with new phones or not, experience excessive battery drain upon installation of iOS(x+1), and excessive battery drain is only exceeded by excessive griping about this predictable phenomenon that is always rectified by an iOS update.

    ReplyDelete
  41. Don’t worry, the next super-duper iPhone 17 will fix everything wrong with iPhone 16. 😆

    ReplyDelete
  42. Nobody cares, but I can back this up profoundly… Haven’t experienced this frakin iPhone 7… And I’m talking about the isolated case of the first version of a big update like iOS18 - massive drains - I don’t know what else to turn off any anymore

    ReplyDelete
  43. 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.

    1. Camera button is the new Force Touch.

    4. That's accurate.

    5. The camera control -don’t call it a button- button is not great in practice. Too fiddly for accurate adjustment and it hides a multitude of sub-features - a hallmark of poor design

  44. This year I upgraded to 16 Pro, not the 16 Pro Max. I decided not to wait several months until the Pro Max becomes "in-stock" at my local carrier store. There was noticeable battery drain when everything was loading on my new 16 Pro. After that battery seems to be alright.

    It is great how easy it is to transfer all the stuff from the previous Pro Max onto the new Pro using iCloud.

    ReplyDelete
  45. Glad I didn't downgrade to a 16 Pro,..running 18 PB on a 15 Pro and battery longevity has been brilliant!

    ReplyDelete
  46. 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.

    ReplyDelete
  47. About time this issue gets some recognition, this phone feels like a big downgrade from the 13PM

    ReplyDelete
  48. Those who claims that they have no issue could be apple spys. The battery drain is terrible.

    I had my 16 pro max charged to maximum using apple charger and usb cable. iPhone was left unplugged since 7 hours ago, unused. It was kept in air fconditioned room at 20degc. I woke up and it’s 97%. 3% drained for no reason?

    I’m returning it anyways. Could be defective unit. Could be desay battery.

    ReplyDelete
  49. 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.

    1. I did every possible and imaginable actions. Aod,promotion, Siri, background refresh, min brightness, airplane mode, etc and etc. 3 % drained overnight……. :(

      Delete
  50. No problems for me with my 16 Pro, and haven't seen it below 50% in the 12 days or so I've owned it, including a week on vacation. I keep AOD off, and background refresh off for the vast majority of apps, and I'm a pretty lite user. 18.0.1.

    My watch, however, on the newest watchOS?...awful. It has gotten quite cold here lately, and I spend a lot of time outside, so maybe that's it? I put a sweatband over it today during my trail run, and it seemed to do a bit better..maybe.

  51. I am definitely waiting for the 2nm Apple silicon models. iPhone 18.

    Before I switch back to iPhone from Samsung S24.

    getting awesome battery life after a few updates on my S24

    ReplyDelete
  52. My experience has been the reverse. I went from 13PM, with battery I could stretch to two days fairly easy, to a hot 15P I had to charge midday daily. I switched to a 16+ and I end the day with at least 35%, usually >50%, without midday charging.

    ReplyDelete
  53. Running 18.1 on my iPhone 16 Pro and battery life is as equally disappointing as it was on my iPhone 15 Pro.

    ReplyDelete
  54. So is this 15 Pro user.

    ReplyDelete
  55. And I’m still running the iPhone 14 Pro and the battery life is awful.
    My iPhone 11 Pro Max was the best, that lasted forever.

    ReplyDelete
  56. We‘re a month into launch and we’ve only had 1 iOS update. There are definitely more iPhone 16 bugs than that and even more iOS 18 bugs.

    I get the sense that Apple is fully focused on Apple Intelligence in 18.1 but their poor release day quality control for hardware and software is showing.

    As a day 1 adopter, this is getting old and frustrating.

    1. If people held off in noticeable numbers until this stuff got ironed out it just might shift priorities. But it would have to be enough to change their quarterly results

      Delete
    2. That’s not an excuse . “Oh we only released it for a month” I mean they had months to do beta and before they freaking INSTALLED it into iPhone 16 devices it should’ve solved all the battery drain issues

      Delete
  57. I wonder if it’s the compressing of photos to iCloud. The setting where it keeps the original up there but compresses a version on the phone

    ReplyDelete
  58. I just power my phone off for most of the day. Saves a lot of battery life.

  60. Is this a surprise to anyone?!? iPhone 16 users should have upgraded to the iPhone 17 by now. Thank you, next!

    ReplyDelete
  61. Totally subjective, but my 15 Pro has been my least favorite iPhone since the 3GS, which is when I worked at Apple and saw casing issues up close. Only reason I dislike the 15 Pro is battery life, and I’ve experienced significant battery drain and overheating on 18.1. It’s the only update I’d like to see in a new phone. I recently held my brother’s pink 16 Plus and it felt fantastic. Camera Control feels like a software update or two away from being really cool. I feel for the software engineers at Apple. I doubt they’re ever sleeping.

  62. I had the issue with my 16 Pro Max while running on iOS 18. Since iOS 18.0.1. battery is back to normal.

    ReplyDelete
  63. Excellent battery life on iOS 18 and 18.0.1 on my 15pm.

    ReplyDelete
  64. no battery life problems here its great but there is some excessive (home lock screen battery) 10% Lockscreen use over the day usage...... hope they fix that.
    the lock screen when off is draining more then it should. but the battery is so big and the a18 pro so efficient i still have two day battery life while only. charging to 90 % and beeing left with 20-30+% after two days.


    they just need to fix the lockscreen drain and its going to be really great.

    ReplyDelete
  65. got 16 Pro Max last Friday, battery was meh at first, now it seems better but still not nearly as impressive as some of these reviews are saying....cmon, a day and a half off 1 full charge, please, huh?? always on is off, 60hz is on....

    makes me wonder what iOS these reviewers are really getting and possibly specially tuned batteries in their phones etc
