iOS 17.5 Battery Drain and Heating Issues

Previously I was on 17.4.1 iOS with my new iPhone. I was pretty fine and satisfied with the full day battery life of the phone. Recently I updated phone to 17.5 now I am regretting it. The phone is not able to provide me full day battery. I have to charge twice in day which was previously not. Phone is heating more than previous. Idle state discharge of the battery is increased

I have no problem with battery life on 17.5; you should look into what is using the energy. And it has been less than 24 hours since you were even able to update, so it is really meaningless to say that battery life is down without more time to collect data.


If battery life is down then SOMETHING is using energy that wasn’t; battery life doesn’t just vanish into thin air. Basic things to check:

  • Force-restart your phone.
  • If you have VPN installed, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile. If that fixes the problem you can reinstall it.
  • Go to Settings/Battery and see which apps use the most energy.
  • Wait a couple of days; sometimes after an update iOS will rebuild its database indexes, which can use extra energy. If you leave the phone plugged in overnight (which you should do every night) that will speed up the process.
