My battery health on my 12 pro max started at 87% when I started beta 1, and it went down a whole 5 percentage points to 82% now. Does degradation accelerate as time goes on? Or is this just recalibration? It's not like the number has been jumping all over the place, it's gradually been declining.
Mine has also gone down 5 points. It was 100% since October, then dropped upon b1 install, and has been gradually dropping. It’s 95% now.
 
That's happened forever. Probably because most (all?) IMAP accounts work using Fetch rather than Push, so you just have to wait for the next Fetch run.

Plus, for reasons I don't understand, the iOS Mail app doesn't support IDLE. The MacOS version does.

What feature is missing because of non support of IDLE ?
 
If anyone’s having issues with Instagram heating up their phone after a few minutes, like really hot, it’s not fixed in this beta.
 
Running the beta on all devices, SMS syncing was always broken b1 and b2. Downgraded Mac as first step to back out, as I need this working correctly

Has anyone already checked for this? Not sure if the glitch is stemming from Sonoma beta or iOS iPad betas..
Is SMS syncing between devices resolved in this beta ?

I have this same problem. When I installed first beta I had 88%, now I have 84%… this is weird. On my Apple Watch battery lose 2% in this same time.

Battery is very hot.
 
Off-the-cuff guess: iOS 17 might have an updated method/algorithm for determining battery health that might be more conservative than whatever was used in iOS 16 and earlier versions.

As for why there are large variations right after installing a new beta — is anyone checking battery health periodically while running a given beta, or only immediately after installing the latest one? Large step changes (2+ percent all at once) seem unlikely if a device is operating normally — what might be happening is that the health percentage has been decreasing steadily (and unnoticed) over a number of battery cycles as it is recalculated during operation, but the change is being noticed only after upgrading to the next beta.

Alternatively, newer betas may themselves use different algorithms than previous betas, and are simply updating the displayed battery health — which hasn't actually changed from a physical battery capacity standpoint — using the newer algorithm.
 
I thought I read in the b2 thread that people were having issues with 5G but maybe it was just a one off?!

I got this on b2 with AT&T. I’d say it was ok

Finally jumped on the beta train with my 14 PN and installed beta 3 OTA. So far so good. Battery drain doesn’t seem unusual, the heat went away after 20 minutes of indexing and I’m not seeing any bugs as of yet. YMMV but I’m satisfied with this performance so far, other than the default iOS 17 wallpaper not showing up.

Edit: my current lockscreens are no longer working. They show up correctly but once activated they all just show a black screen. Odd.

B2 had that issue, solution was to change your region and back, you can try it out:

100%>99% takes ages then it seems to go quicker

Saying that my 12 Mini has been suspiciously stuck on 81% for almost a year now which makes no sense - Apple trying to avoid free replacements?
