Battery draining overnight

Suddenly, I think maybe after the last IOs update, my iPhone 12 battery is draining very quickly. Last night I went to bed and the battery was at 86% but when I woke up it was down to 10%. Ive tried doing various things advised by Google and YouTube but no good. HELP

Experiencing sudden battery drain on your iPhone after an iOS update can be frustrating. Here are some steps you can take to try and resolve the issue:


1. Check Battery Usage: Go to "Settings" > "Battery" and review the battery usage by apps. If you notice any particular app consuming an unusually large amount of battery, it might be the culprit. Consider updating or reinstalling that app or checking for any settings that might be causing excessive battery usage.


2. Restart your iPhone: A simple restart can sometimes fix software glitches that could be causing battery drain.


3. Update iOS: Make sure your iPhone is running the latest version of iOS. Sometimes, new updates can include bug fixes that address battery-related issues.


4. Check Background App Refresh: Go to "Settings" > "General" > "Background App Refresh" and either turn it off completely or select specific apps that are allowed to refresh in the background.


5. Disable Location Services: Some apps constantly use your location, which can contribute to battery drain. Go to "Settings" > "Privacy" > "Location Services" and either turn off location services completely or restrict them for specific apps.


6. Check Push Email: If you have multiple email accounts set up on your iPhone, consider changing their email fetching settings to manual or fetch instead of push.


7. Reset Network Settings: Go to "Settings" > "General" > "Reset" > "Reset Network Settings." Note that this will reset your Wi-Fi, cellular, and VPN settings, so you'll need to re-enter your Wi-Fi passwords.


8. Disable Widgets: Remove unnecessary widgets from the Today View by swiping right on your home screen, scrolling to the bottom, and tapping "Edit."


9. Check for Rogue Apps: In some cases, certain apps may misbehave and cause battery drain. Try uninstalling recently installed apps one by one to see if the issue improves.


10. Restore as New: If none of the above steps work, you can try restoring your iPhone as new through iTunes/Finder (make sure to back up your data first). This will reinstall the operating system and eliminate any software-related issues.


If the problem persists after trying these steps, it's possible that there might be a hardware issue with your iPhone's battery. In that case, it's best to contact Apple Support or visit an authorized Apple service center to have your device inspected.


Remember, battery life can vary based on usage patterns, signal strength, and other factors, so occasional fluctuations are normal. However, a significant and persistent drop in battery life after an update is worth investigating further.

If your iPhone's battery is draining even when it's not in use, there could be a few possible reasons for this issue. Here are some steps you can take to troubleshoot the problem:


  1. Go to Settings > Battery and see which apps or processes are consuming the most battery. If you notice any particular app using an unusually high amount of battery in the background, it might be the cause of the drain. Check the iPhone battery health and usage - Apple Support (IN)
  2. Some apps refresh their content in the background, which can consume battery. You can disable background app refresh for specific apps by going to Settings > General > Background App Refresh and toggle off the apps you don't need to update in the background. go to Settings > General > Background App Refresh and turn on Background App Refresh. -->Switch apps on your iPhone, iPad, or iPod touch - Apple Support
  3. If you have multiple email accounts set up on your iPhone and use the push email feature, it can drain your battery. Instead, consider changing your email settings to fetch data manually or at longer intervals. Go to Settings > Mail > Accounts > Fetch New Data and adjust the settings accordingly.
    1. Push Mail: Whenever possible the email client will push mails to all your devices.
  4. Fetch Mail: You need to set How you want it to be fetched, Automatically, Manually , Hourly,Every 30 mins, every 15 mins
    1. Automatically: will fetch when the iPhone is powered and on WiFi
  5. Manually: with fetch when you open email, open Inbox and swipe down
  6. You get an email notification as soon as the client server receives an email and your device is connected to internet, irrespective of whether the mail is in your device's Inbox or not
  7. Some apps constantly track your location in the background, which can use significant battery power. You can manage and restrict the location access for apps by going to Settings > Privacy > Location Services and adjust the settings for individual apps.
  8. Keep an eye on Wi-Fi and Bluetooth settings. Sometimes, if Wi-Fi or Bluetooth is left on even when not in use, it can contribute to battery drain. Make sure to turn off these features when you don't need them.
  9. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
    1. Restart the device. That's it.
    2. Still not solved --> Force restart iPhone - Apple Support
  10. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
    1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
    2. You can return settings to their defaults without erasing your content.
    3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
  11. Make sure you have the latest updates installed.
    1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
    2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)


If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

Update on battery draining problem .......... I ended up phoning EE and I was advised that the problem may be with the charger cable. It was suggested that I use a different one and the battery might heal itself. Needless to say I didn't believe a word of it. I then looked at the actual charger and noticed a couple of small cracks in it so I immediately ordered a new one. Anyway, in the meantime I used a cheap cable, one I'd never used before, to charge up my phone and so far everything has been fine. Fingers crossed problem is solved. Many thanks to those people who offered help.
