Hello. Eversense I've upgraded to iOS 7, I've been having significant battery drainage issues. I've turned off Bluetooth, airdrop, background app refresh, flash light, turned on screen curtain, turned briteness to 0, and closed apps In the app switcher. I have my autolock set to 5 minutes. I lock my screen when I'm listening to something. Yesterday, I've charged my phone twice. AT 6 O'clock in the morning, my battery was at 81%. Then, I've started to move apps around to folders. AT 8 o'clock, it was at 52%. At 9:00, I've turned on Bluetooth to pair with my braille display. I've turned it off after I was done. At 1:00 PM, it was at 20%. I've locked my screen from 11:00 to 1:00. Not sure what to do. I've also noticed when I press the volume buttons, voiceOver says screen locked a couple seconds later. Not sure if the screen lights up or not.
