iOS 18 Battery Life Thread

I've got an iPhone SE (3rd gen) and since updating to iOS 18.0 last week, it's been burning through battery overnight due to Find My and Home apps. Not really sure the line-up, but I'm guessing something Bluetooth related is causing it. Unfortunately, deleting the Find My app doesn't seem to solve the problem (and I need the Home app). I'm traveling for an extended period in the near future, so Apple better get their **** together and fix this problem.

It’s not been too bad! Ending the day with around 30%+ with 6-7 screen on time. Charging once per day.

Like you said it’s not great for a Pro Max device but far from terrible.

How in the world you iPhone doesn't drain during night? Mine no matter if it was 15 Pro or now 16 Pro loses 7-8%. Mostly (probably) for Find My and Main/Lock Screen

I don’t know lol I put low power mode on when I go to sleep, maybe that helps? Idle drain is great on my 15PM running 18.1 public beta.

Downloaded 18.0.1 on my 16 pro last night and charged to 95% limit last night. Today it has been better, but I wouldn't say outstanding. I will wait to judge until 18.0.1 has had a few days to settle in.

I’m having a similar experience on my 16 pro also. Better but still only marginally better than my 3 year old 13 pro had been. The 13 pro had a battery down to 82% health. Here’s hoping they figure out what’s going on or it just settles in.

“I’m hoping that 18.1 resolves all these issues, but who knows? It’s surprising that your 13 Pro is only slightly behind at 82% health.”

You need get used to this. Same case with iPhone 15 pro. They’ve never fixed it. Maybe these new are not that super power efficient or Apple just doesn’t care anymore.
 
I am charging only every 2nd days with normal use since 18.0 and 16P.
Great for me. With 18.0.1 it might be Even better.

Every two days with 18.0? How? Do you use your phone at all? I am pretty serious. My iPhone loses every single night 7-8%. Today from 7 am I’ve lost 20% (till 16:00) doing absolutely nothing.
I am still on 18.0 on iPhone 16 pro.

The battery test from iAppleBytes gives a very bad score to the iPhone 13, the device with the same A15 chip as my SE 3.

I wanted to update but now I’m between updating to iOS 17.7 or 18.0 with its numerous bugs…

What would you do?

EDIT: I think I’ll update to 17.7 and wait for a more efficient iOS 18 version.

Hi all new iPhone 16 Pro users, are you all facing this issue (as mentioned on the title)?
If yes, how do you all resolve it so that home & lock screen is not draining battery.

P/S My homescreen got no widgets.
 
I’m getting massive battery drain on my iPhone 15 after I updated to iOS 18 even though I updated on day one
 
Since installing 18.0.1 on Thursday night, my experience has been quite Jekyll and Hyde. At times, I’m really impressed with the battery life on my 16 Pro, yet other times, I lose 2% of battery just from it sitting idle on the table for 10 minutes. I really don’t understand why this is happening; I’ve never encountered this issue before. Well before iOS 18.

Are you using any lock screen widgets, and if so, which? I was having this issue (particularly overnight when my phone was idle and battery saver is on) so I removed my lock screen widgets and my battery drain went from 20% overnight to 10%. I typically have fitness rings, temperature, and device battery gauge widgets and I will try adding back widgets to see if one was the culprit. I have a sense it may be the battery one since the problem stopped briefly last weekend when I was out of town away from my AirPods Maxes which also appear to be experiencing significant standby drain.
 
Wow. That’s incredible. I was starting to get excited about 2.5 hrs screen on time with 50% left on my 16 pro.
