Unlikely, even if you shut the device down when you attach a charger it goes into either a semi-on state or just turns on entirely. Even if you shut it down while it’s plugged in.
- jchw 6y agoI thought the “semi-on” state with the battery display was still just firmware and not full iOS. If not, what exactly is it booting to display that? Surely not an ordinary kernel?
- userbinator 6y agoMy experience is with the MTK platform but Apple may be similar; in which case the battery display is done by neither "firmware" nor the full OS, but an intermediate component: http://www.lieberbiber.de/2015/07/05/mediatek-details-little-kernel/ http://www.lieberbiber.de/2015/07/05/mediatek-details-little...
- saagarjha 6y agoI believe they are just one of the things you can "boot", alongside regular iBoot in the boot partition and loaded appropriately by SecureROM. I'm pretty sure the images at least ship inside IPSWs.
- londons_explore 6y agoThis is correct. That's because the "Charging" screen also sometimes has OEM or carrier branding on, and error messages that might need to be i18n translated eg. "battery failure", "overheat". It's much easier to do that with a separate component rather than give every OEM the ability to flash and recompile firmware.
- Nition 6y agoSide note: I wish that feature could be turned off. Sucks to turn your phone off for the night, plug it in to charge, and it boots back up (it's not the semi-on battery display either, it does a full boot to iOS).
- mlindner 6y agoWhy are you turning your phone off for the night, is the real question.
