iOS 18 Battery Life Thread

[morganthomas757]

Down to 95% battery life on my launch day 15PM with 306 battery cycles.

 

[ATmahe]

94 % with 330 cycles on mine.

Battery drain has been horrible on my M4 iPad. It drained 35% overnight with no use. iPhone has been good. Apple Watch Ultra 1 has had the worst battery life I’ve seen.

No real battery drain on 15 Pro Max, 13 Min and the latest Apple Watch on beta 7. Feels the same as iOS 17 to me under daily usage.

Losing 15% from 95% to 80% after playing Clash Royale for an hour is a bit much for the 15 PM!?
Or completely normal?
My iPhone was warm while playing, maybe that’s why I lost 15% in an hour?
What do you think guys?

So no heat and drain? Understood that right?
Yeah that’s good I guess.
I get average 6-7 hrs with my 15PM, not that good but expect to get better results when beta is over for iOS 18.0 and it’s finally released

I don't play games..I use social networks a lot..photography, editing..the only thing when the temperature is a bit higher than usual is uploading data to iCloud..or filming in 4k resolution

So you say you have no drain or heat issues?

There should be a class action suit lodged against Apple for releasing poorly coded firmware which is results in excessive wear and tear in particular to batteries

The heat generated and battery drain ( resulting in more charge cycles ) definitely shortens the lifespan of the battery.

Even the final release versions are absolute rubbish with lots of bugs.

iOS 17 has been a total disaster

Haven't experienced any issues of note throughout IOS 17 release. iPhone 15 Pro.

iPhone 15 Pro Max here running PB5. Battery life is mediocre at best. I can barely make it through a day with 7 hours SOT. Phone gets hot during the day, but that could also be related to the high summer temperatures (screen brightness blasts at full brightness when I’m outside). I don’t even think of playing games when running a beta I hope they address this - weren’t their times when you could almost get 9 hours of SOT with a Pro Max device?

I’m not happy with battery life and device getting warm with my 15PM on public beta 5. Not even doing any intensive stuff and I can feel it warming up, this includes 3rd party apps and stock iOS apps & functions. I hope this gets addressed asap this coming week of betas…

Have submitted feedback with my concerns.

I experience the same thing with my 15PM, barely make it through the day too, with average 7hrs SOT
Idle battery drain is also there - charged to 100% yesterday evening, woke up to 83%…
Random heat is also given over the day randomly

I have committed feedback so many times with this problem, hope this gets addressed next beta or in the RC

We can only hope! Imagine if this doesn’t get fixed 🙈

Yeah, I just don’t believe that this is getting ignored

Wondering if it would help to DFU reset my 15 PM when the official release is out…!?

 

[Stiille]

Ah man it’s 04:26pm and my battery is gone down to 45%, can’t reach a full charge lasting the whole day, this needs to get better

my battery life on my iwatch ultra 2 is crazy bad

Apple community folk wisdom would tell you yes. Practical data says no. Just let it run and use your phone like normal. I am speaking from experience having done many, many DFUs.

Besides bigger batteries, the iPhone 16 series needs a vapor chamber, what good is stuff like ray tracing if the phone has to throttle and be dipped in ice water to prevent it from melting?

Or maybe use one of the process shrinks to focus on efficiency instead of performance, at least on the A series chips.

If they want to release a slimmer, lighter iPhone 17, they really need to consider this approach of a more efficient SoC.

I lose 5-10% battery within 20 minutes using a app which used to be underwhelming for my iPhone - I mean what the actual heck is happening, the iPhone heats up and my battery life flows down the river…
Faster than I could imagine.
This needs to be addressed asap

Or maybe my 15PM is broken???!

It’s beta software. It’s normal to have bugs and issues like the one you’re having.
