Battery drain issue after iOS 18.7.2 update

Hello Apple Support,




After updating my iPhone XR to iOS 18.7.2, I’ve noticed a major battery drain issue. The battery percentage drops quickly even when the phone is idle, and it sometimes gets warm during light use.




I’ve already checked background apps and battery settings, but the issue remains. Please look into this and let me know if there’s any fix or upcoming update to resolve it.




Thanks,


Fozle

Just posting this comment cost me 2% of battery.

Post a screenshot of what you see at Settings > Battery with the green battery graph using the last 24 hours option and the top apps consuming your battery. Some apps have background activity that will consume your battery even when they are not being used. If you updated on the day 18.7.2 was released, then you are just now at the 5 day mark where you should be seeing the file indexing and photo optimization being completed after the update. If Home & Lock Screen is showing up in that screen shot then that is a good indication that the background indexing is still going on.


Little confused when you say your Phone and Battery are new, but say that your Battery Health is 92%. That just brings up more questions:

  • What model of phone do you have?
  • Where did you purchase it?
  • Did you replace the Battery at Apple/Authorized Apple Service Provider, or was that done someplace else?
  • Was the phone purchased as refurbished/used where you have no idea if it is a genuine Battery?

Marc we both tell you the same thing. I had the same versions of meta apps with iOS 18.6.2 and the same with ios 18.7.1. I updated them after I noticed excessive battery drain with ios 18.7.1. The battery drain is worse with ios 18.7.2. What is the point on deleting meta apps and use them on safari? Of course the battery will be better because it is not pleasant to use instagram on safari. What is the point having an iPhone without whatsapp? You do not provide any specific solution. Only supporting Apple

Yes I’m using an iPhone 15 pro - my battery health dropped 2% in a week after I did this update and I’ve noticed my phones screen is super unresponsive and laggy and my phone is now heating up a lot more and a lot hotter. It’s in a case toy case and never gets anywhere near water or dust or anything. I’ve tried to reach out to Apple for lots of different issues that I have had but the Service just isn’t there anymore unfortunately.

Why Instagram, Facebook and WhatsApp work so much in the background? I have disabled app background refresh,

Not surprising they are all Meta apps and you would have to ask them why they are consuming so much of your battery. Turning off Background App Refresh is only to prevent UI updates for apps in the background, they are still running background processes that consume your battery even when the apps are not being used.


Meta allows you to use their apps for free and that means you are the product they are selling to generate the billions of dollars every quarter. It was actually $2.71 billion dollars last quarter. The amount of information that they are gathering from you does take power on your device and that data is sold to advertisers for income. Just take Instagram for example and look in the App Store what data they are using, and multiply that by 3 to account for their other apps on your device:

  • Contact Info
  • Health & Fitness
  • Financial Info
  • User Content
  • Browsing History
  • Usage Data
  • Purchases
  • Location
  • Search History


Just do a simple test and remove those 3 apps and compare your Battery usage. You will be amazed. Apple gives you the tools to see the apps that are consuming your battery, and it is up to you if you want to use them or not. If you do not like the way an app performs on your iPhone, the developer of the app is the one who could provide an update to resolve the problem. Even Google has called out Meta for draining the battery on their Android phones, so it is not specific to Apple, and you will see the same reports in the Samsung/Android Support Sites too.
