Hi all,

Yes, it's launch day, but as we're all starting to receive our phones, it's time to start this thread off!

What's your battery health, and what's your cycle count?

For added iPhone 17 fun, what's your manufacture date and are you using adaptive power/charging limits?

I'm somehow already on 1 cycle, with adaptive power on, no charging limit.

picked my orange 17PM up at the Apple Storeyesterday. Later in the day ran coconut battery and my phone is at an actual higher capacity than design capacity ;). I have "Adaptive Power" turned off, no charge limit but opted charging turned on.
Will see where it's at in 6, 12 months etc
How about yours?

I have the 17 pro with sim card tray so (smaller battery here is Australia) and the battery life for me on day 3 is abysmal. Off the charger at 7.00am and down to 50% by lunchtime with light usage. My old 15 pro max easily out performed this. Will it improve?

It appears I got a good one, although the manufacturing date is completely unrealistic.

Hi,

I've got a new base iPhone 17 coming from a 15 Plus.


For me, the battery is bad. I only have 2h SOT with about an hour of calls (with good reception).

Is this expected? System is fully set-up and there's no warning that the runtime might be slower because of that.

I‘ve exactly the same problem. I‘m comming from a iPhone 13 Pro with only 80% battery capacity and the 17 pro doesn‘t feel like an improvement.
I only get up to 6 and a half hour screentime out of it and when I see all the other users here I don‘t know what I‘m doing wrong.

I've been having significant battery and heat issues with my iPhone 15 Pro since iOS 26, so I don't think it's the phone's fault, but rather the update. It could also apply to the iPhone 17 Pro, since they all ship with iOS 26.
 
I did have a 16 pro max but dropped to the 17 pro due to preferring the size so I knew battery wouldn’t be as good. But this seems really really poor

I had it since Fridays launch so can’t see that it is still indexing. But it’s far from ok

The iOS battery stats in the battery settings will tell you if there is high use from any specific app. If not it might be an iOS 26 bug that gets fixed soon. It's either that some people trigger a specific setting that causes a battery drain bug to occur or they use particular apps that cause the problem.

For example the 15 Pro at launch had widespread reports of overheating here in the forums and it turned out to be limited to few specific apps and Apple later provided an update to work around that. And that's how the 15 Pros got the reputation of nonstop overheating.

Then the 16 Pro had significant bugs out of the box with iOS 18.0 and some people initially reported all kinds of troubles upgrading from their 14 Pros and 15 Pros to the new 16 Pro. Now the 16 Pro is known to be relatively bug-free and is solid on iOS 18.6/18.7.

It's the same thing every single year when you buy the latest iPhone on launch day...
