So I noticed incredible non reproducible battery drain on iPhone 6 Plus.
My apps keep crashing and so does the springboard, it doesn't run very smooth for me and seems to be very unstable. (especially whatsapp, snapchat,..)
It also keeps heating up a lot (noticed even when I listened to music with the new music player, my phone heated up on the right corner on top).
And the carrier doesn't show up anymore, it just shows 'iPhone' instead of the carrier?
It shows whatsapp, snapchat and tumblr background activity - but I switched off background app refresh. And the using times also can't be right.
I did a clean install.
Now I switched on low battery mode to see if it changes anything.
But I like the new font and the lower keys on the keyboard, the new spotlight search area is great imo and there are more things I really like about iOS 9... Especially the new music player. (but it's buggy like everything seems to be buggy)
But is iOS 9 really 'rootless'? Can't find anything about that.
