Beta for me has been pretty good..no issues with CarPlay, Wi-Fi drops, batt life is pretty good as well..

Running Verizon on Sim + Tmobile on Esim.

Just noticed 5G UC on T-Mobile tower near by.. pretty impressed not no 1GBPS but better than before the 50MBPS I had previously.

again, for me the 15.3 b1 is the best beta ever made.
No bugs at all, incredible battery, all the bugs present in the 15.2 fixed for me.

Are you saying CarPlay might be fixed for some like me when connected to my CarPlay via wireless Apple maps and Google maps shows blank screen.
 
15.3 has been fine other than a few random freezes for me. I have noticed my data speeds are less than when comparing it to my gfs 13pm on the same network right next to my phone. Wonder if the modem change has something to do with it.

blah blah calendar events removed from widgets on iOS/MAcOS after 15 minutes ... my regular moan

home app keeps refusing to see my Hue hub

Apart from the above two, I have no issues. Quite happy with iOS 15; it even performs well on my backup 6S phone.
 
After several days of use, I notice worse coverage than ios 15.2. the downgrade of the modem will have something to do I suppose. System data is consuming space like crazy, and there is no way to control it. Neither restoring has solved this. also the representation of the storage goes wrong, because I deleted a 1Gb video, and not only did it not lower the occupied space, but it also increased by 1.5Gb, all in System Data. apple does not know how to control this section.

Since on beta 1, have noticed that AutoBrightness has not worked.
Tried Off/On, Reboot, Hard Reboot, all have had no real effect.

13ProMax is working okay except at times when in low light it will hunt for the correct level.

This really makes me wonder what they're doing with Auto Brightness/True Tone. I flipped on a light this morning and saw the brightness fluctuate pretty drastically very quickly and I could also see it shifting the tone pretty agressively. Both of these features are usually gradual and not near as noticable.

I suspect it's the modem firmware that was older than the latest one in 15.2 causing your issue. The 13's are still getting modem updates pretty regularly to "fix" things. The XR modem FW has not changed, and I am seeing zero difference in speeds from 15.2 so I doubt its being caused by iOS.

They’re trying to fix the offensive deep yellowness of TrueTone. Guess I can wishful think. 🤣
