iPhone 6s crashes down after update

After the update 12.0.0, my iPhone 6s started to randomly crash down and I noticed that when I restart it again, the battery will be 1%. But I shut it down and restart it, the battery will be 97% or 99%.

I was hoping that the update 12.0.1 will solve this problem but it still persisted. Also, I noticed that sometimes, the cellular data will be switched off.

It's really causing me many problems since it crashes down without any warning and while I'm in the middle of something!

Another thing I noticed after the update is that the battery is fastly consumed...

What should I do?

iPhone 6s, iOS 12.0.1, null

Greetings, HaneenM.


It appears that your iPhone 6s has started to unexpectedly shut down while you're using it. You've also noticed a discrepancy with the battery level when it does, and I'm happy to help.

If you see "Your iPhone battery may need to be serviced" -- An iPhone shutting down unexpectedly sometimes indicates an issue with the battery. Tap Settings > Battery to see if this notice appears.


How to back up your iPhone, iPad, and iPod touch -- If your iPhone didn't qualify for the program, and there wasn't a notice about the battery, please be sure to have a fresh backup to keep your personal information safe. In order to back up your Health data, the backup needs to be encrypted. iCloud does this automatically, but iTunes doesn't.

Let me know how that goes, and take care!
