Hi! Just downloaded the IOS 26 beta software to my Iphone 15 128gb and during the second phase of installation of the update (when the phone start rebooting a few time) my iphone showed the display of low battery with the time displayed on the top left corner of the screen, even though my Iphone was pluged in during the full time of the install and had more than 50% of battery before launching the installation.
So far-here is what i know:
- I wouldn't be able to confirm if the install was successfull or not
- i tried forced reboot a few time but i keep landing on the low battery page
- some other people are experiencing the same problem as i am as i could confirm on the reddit dedicated to the IOS26beta page
Had this issue on my 16 Pro Max, had to put the phone into DFU mode and restore it to 18.5. Haven’t tried to install 26.0 beta again yet. I recommend trying these steps to enter DFU mode if you haven’t tried them yet. It was the only thing that worked for me:
“First, quick-press the Volume Up button, then quick-press the Volume Down button. Then, press and hold the Side button until the screen goes black. As soon as the screen goes black, press and hold the Volume Down button for 5 seconds. After 5 seconds, release the Side button while continuing to hold the Volume Down button for an additional 10 seconds.”
