First, check your iPhone's battery capacity in the Settings app. If it's below 80%, it may be time for a battery replacement, though we still can't rule out a software or firmware issue.

Next, try restarting your iPhone. This can fix a minor software bug. If that doesn't work, back up your iPhone and put it in DFU (Device Firmware Update) mode. A DFU restore erases and reloads every line of code on your iPhone.

If your iPhone battery still isn't calibrated after a DFU restore, you may have to get your iPhone repaired.

My phone will shutoff on its own at 70% then come back on at 10% then will come back on again with 70%

you guys should make a video about the differences of an iCloud backup VS a Mac or PC backup ( and the benefit of encrypting your backup too to recover health data, Passwords etc ) cos i still Backup my device via finder, even if iCloud is more convenient, some people doesn't know the advantages of having a local backup .

You don't need to put the iPhone into DFU mode to fix software issues. Recovery mode is just fine for that as well and it's easier to use (1. press & release volume up, 2. press & release volume down, 3. press & keep holding the side button until the recovery mode screen appears). DFU mode should be used when you want to downgrade your iOS. The only difference between DFU and recovery mode is, that the iPhone will not boot using iBoot in DFU mode. iBoot would not allow to change the iOS version, but recovery mode still removes the iOS and reinstalls the current version. In DFU mode you could choose older iOS version (if they are still being signed by apple) if you have the feeling the current iOS is giving you trouble.

! How do I disable the obtrusive ANNOYING iPhone “Low Battery” warning notifications?

Or change settings to only show when the battery falls below 5% (or some other custom setting)

I keep my iPhone on low power mode to conserve battery life. When it recharges to 80%, it switches to full power, which is very frustrating. Is it possible to disable this feature?

My iPhone 11 turns off random after that the battery will be low and turn off again eventually and the battery will go back and cycle repeats

[wrighty]

My iPhone 12 Pro Max restarts itself randomly when I plug in the lightning earphones. It’s frustrating and I’m wondering if it’s worth going to the Genius Bar to have it examined.

[emiliog.]

Why did my Optimize Battery feature stop working on my new IPhone 13? It no longer stops charging at 80% message. ?? How can I fix this? Tried everything. All items necessary are on.
