Drain Battery & Overheating After Upgrading to IOS 13.3.1 - On Normal Battery Mode Only.

My phone is I phone 7, and I have recently updated from IOS 10.1.1 to 13.3.1 and am suffering from:

1- on normal battery mode, very fast battery drain with overheating and this is avoided by switching to low power mode.

2- on normal mode & PC connection, the battery drains rather than charging except I switch to Low Power Mode.

The following steps have been tried with no effect:

1- switch from 4G to 3G

2- stop all background app refresh

3- Stop email fetch

4- Stop automatic downloads

5- Stop photos from accessing I cloud

6- discuss the issue with Apple support and sent diagnostic file, none of the support advice worked.


Please HELP

iPhone 7, iOS 13

Try some of these options too.

  1. Put on Low Power Mode
  2. Put Auto Lock On (1 min):- with low power mode it will be 30 Sec
  3. Put Auto Answer Off
  4. Disable Push notifications for apps you do not use often
  5. Enable Auto Brightness:- Settings > General > Accessibility > Display Accommodations > Auto-Brightness [Enable]
  6. Manually lower brightness from Control Center
  7. If you Want to watch continuous Video. Stream it on TV or a Monitor
  8. Don't force close apps; Apps which are not on frontend screen are paused by the system to save energy. Apps require more energy to re-launch. Apps which are open in the background use large memory is a myth and quitting them is counterproductive
  9. Location services to be allowed only while using the app
  10. Set your iPhone to fetch email and calendar data from internet less frequently
  11. Turning off Background App Refresh 
  12. Charge before it drops below 20-30%
  13. Try connecting to trusted Wifi where ever available in stead of Cellular
  14. Enable Airplane mode in areas with bad cellular and wifi coverage. Your phone keeps trying for reconnection with the missing / weak network. This uses lot of energy
  15. Switch off Wifi & Bluetooth while in Roaming or Not in Range
  16. Enable "Wifi Assist" : Settings > Cellular or Settings > Mobile Data > Wi-Fi Assist [Enable]
  17. Periodically Check your Battery Health (Settings > Battery > Battery Health)
