iOS 18 Battery Life Thread
- Thread starter gwhizkids

Well, he’s sending my data to engineering for analysis, which will take a week. He mentioned that he thought they’d find nothing wrong, so if that’s the case, I might request an express replacement. At this point, that’s my last hope.
I had the Home & Lock Screen battery drain bug in september on my previous iP14PM after I upgraded to iOS 18.0. That problem went away with a network reset.
Got the same bug again now on my new iP16PM with iOS 18.1. A network reset this time did NOT help. So I went for the iOS 18.2 Public Beta instead. I hope this helps. So far it looks like it's working, but time will tell. At least Home & Lock Screen aren't first anymore on the battery usage list.

I really think there is a background and hidden process which reduces my battery in sneaky way life....
I have never had great battery life with any iPhone and always starting from a scratch install.
If I leave my device on continuously on Youtube or the same page on Safari, I don't lose more than anyone else..... But if I regularly turn on my iPhone for small uses, then my battery goes down faster than anyone else.... As if each time I turn it on there was a specific greedy process.....
The suspects are:
- iCloud (keychain, other ?)
- Homekit
- Gmail sync (calendar, contacts?)
I have disabled background refresh.
How can I investigate more ? It's complicated to use tools for this kind of issue !
In 2019, I have investigated with "Xcode > Instruments" and "Wireshark" but it's very laborious !

At that rate you're looking at 11-12 hours per charge! Freaking battery whisperer! that's significantly better than the 7-8 I was getting on my 15 pm running the 18 and 18.1 betas.
OOOH good that it is cool.... mine has been slightly warm on iOS 18 and 18.1 so far... look forward to it.
I wonder if this is across the board with Android and Apple? Here’s a test below I found interesting…it appears all the Android phones didn’t last as long as the Apple phones. I believe manufacturers are loading so much stuff on these phones they’re constantly running in the background.
Also, it’s weird that batteries get larger but battery life doesn’t last as long.
I agree with you, in this day and age 48 hours should be the minimum these phones get. $1000 and Apple says 12 hours is good? That’s BS
Right? Since when was not making it from the time you wake up to the time you go to bed not expectation for battery life on the smart phone? Honestly I thought my suggestion that it should last at least 16 hrs was reasonable.
For that less usage you have it should really do a better job !
I am right now at 45% battery life with disconnect from charger at 7am and now it’s 7:14 pm
Maybe you exchange your phone and see if it gets better? Or you go with 16 PM?
I agree completely. I don't have crazy high usage.
Yours is exactly what I would expect.
The 16PM is out because I got the pro on launch day, so I am well out of my exchange window. I will push for a replacement if I don't get anywhere with engineering. I think they will see I have a pending case with them and may not want to send me a new phone until that is done.
11-12 hours might be pushing it lol this is how it’s going so far 😄

Has the senior advisor of AppleCare did a diagnostic remotely to pinpoint issues of the battery of your iPhone? Even if it’s just software it would not show up anything on the hardware side unless if it’s obvious that something is malfunctioning in your device.
Indeed it is imperative that they bring it up to the corporate level of the Apple hardware engineers, 🧑💻 they will get this valuable information. Did he say that your iPhone can get battery replacement?
They did diagnostics on my phone 2 weeks ago, said all hardware checked out. No option for battery replacement.Has the senior advisor of AppleCare did a diagnostic remotely to pinpoint issues of the battery of your iPhone?

I’ve had similar issues to Kirby. My senior advisor took the power logs and sent them off to engineering. Engineerings response was that the drain was normal. I had 4 hours of use that day and went from 100% to 1%
That’s purely a joke
Clearly they deny to help here I guess
I believe they are deflecting. Getting them to admit something is wrong is very difficult.
Alrighty, the 16 returned a negative result for hardware issues within battery. 🪫
That is another great explanation for these battery issues. Did you have AppleCare + as well? This is indeed within the logging and intensive processes within iOS; all aspects of how the device performs factor mainly on power consumption.
Apple Watch wearers, read this: if you run watchOS 11.2 beta, you might have noticed your battery health dropped. It is also a bug within the logging processes of watchOS and how it takes strain on your battery health. The condensing of all the generative models we download for Apple intelligence- to the extent of how we use our iPhones for gaming and productivity purposes, matter the most of the battery life.

Don't panic, first of all, are you using the smaller sized iPhone(regular/Pro) , or the big brothers (Plus/Pro Max)? I assume this is a 16 Pro am I correct?
Started my experiment to determine if my iCloud account is the source of the mysterious drain. I have a brand new 16 pro and haven’t logged into my iCloud account yet. Battery life is far superior to what I have been having on my original 16 pro.
So far I have 2 hours of screen on time and haven’t even hit 20% drain. Yesterday I had 2.5 hours of screen on time and 70% drain on my old 16 pro.
Plan to spend a couple days without signing into iCloud to see what happens. Then I’ll sign in but not download any data (no contacts, photos, reminders, etc.). Then finally I download my data. I’ll capture a bunch of screenshots along the way. Hoping to pin down where the drain really kicks in by taking the process in slow steps and building some evidence to take back to apple.
After engineering took a look at my power logs and told me nothing was wrong, I was motivated to prove them wrong or prove myself wrong. Who knows. Maybe the first 16 pro was just a bad phone and this experiment is all just overkill.

Welcome back 😃 it will take a day or so to settle down after the update 👍🏻
Thanks for this test. I know it's difficult to live without iCloud sign-in ! The difficulty is also to have approx. the same usage between two tests.
In 2019, I have created a new iCloud account after standby battery drain on my iPad. And I can't say for sure if it's better or not because now it's my iPhone that's abnormally losing battery life. The only common point is Homekit (Hue bridge, Aqara Hub) or my Airtags.... and Google sync.... but it's very difficult to investigate !
This morning, I have disabled bluetooth on my iPhone 16.... to test....
