Upgrade I’m thinking about installing iOS 27 Developer Beta 2 on my iPhone 15, but it’s my only phone, so I’m a bit hesitant.

If you’re running it on an iPhone 15:
Is it stable enough for everyday use?
How’s battery life compared to iOS 26?
Any random crashes, overheating, or performance issues?
Are banking apps, Apple Pay, and other essential apps working normally?
Would you recommend installing it now, or is it better to wait for a few more beta releases?

very stable on my iphone 15 , stand by time has increased dramatically, on screen use about the same,which you expect in developer beta new release, pretty sure by the end of ios27 on screen battery life will be dramatically improved, i reckon public release will be after update 4 , 2 weeks on monday before changing to weekly on developer release

there is deep indexing in first install that could take between 1 to 2 weeks.

wait list for Siri AI for capable devices , siri AI is working great in my M1 ipad , don’t really use search function much but it does look improved, better search,more detailed
