Protect & Prolong life of your iPhone's Battery:

  1. About the battery usage on your iPhone, iPad, and iPod touch ...
  2. Batteries - Maximising Performance - Apple (IN)
  3. iPhone Battery and Performance



Try some of these options too.

  1. Avoid Screen Mirroring
  2. Put on Low Power Mode
  3. Put Auto Lock On (1 min):- with low power mode it will be 30 Sec
  4. Put Auto Answer Off
  5. Disable Push notifications for apps you do not use often
  6. Keep your iPhone Face down to prevent notifications to light up screen
  7. Enable Auto Brightness:- Settings > General > Accessibility > Display Accommodations > Auto-Brightness [Enable]
  8. Manually lower brightness from Control Center
  9. If you Want to watch continuous Video. Stream it on TV or a Monitor
  10. 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
  11. Location services to be allowed only while using the app
  12. Set your iPhone to fetch email and calendar data from internet less frequently
  13. Turning off Background App Refresh 
  14. Charge before it drops below 20-30%
  15. Try connecting to trusted Wifi where ever available in stead of Cellular
  16. 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
  17. Switch off Wifi & Bluetooth while in Roaming or Not in Range
  18. Enable "Wifi Assist" : Settings > Cellular or Settings > Mobile Data > Wi-Fi Assist [Enable]
  19. Periodically Check your Battery Health (Settings > Battery > Battery Health)

I have been having exactly the same problem over the last 6 days. My iPhone 11 pro has suddenly started running hot and consuming battery power at an alarming rate. It is usually still at 80% when I plug it in at night but it is dropping to 10% now. The battery usage screen indicate that Siri is the main culprit even though I am not actively using it and I have now turned off the Siri options.

My apple watch has also stated to do the same. I wear it in bed and last night it went from 80% charge to 16% overnight. I normally only need to charge it once a day.

Hello

My XS shutdown and was stuck on the Apple logo, force restart would not work, next morning my phone turned on as normal but would not charge. I went to go buy a wireless charger and nothing, usb or wireless no charge. My battery is completely dead! I believe 13.5.1 killed my battery. Am using my old iPhone 7, 5 years old it runs a great. I don’t understand how my 2019 XS just died.
