I have made an automation to disable wifi during night but it does not affect the battery drain. I continue to have 5/6% per day without use while my wife has one my 2/3% with wifi enabled.

I've just bought an iPhone 14 Pro and facing battery drain issue. In fact, it had never quit me ! After 2h of screen active, I'm at 70% and a friend of me is at 88%. So, I'm really updset. What's wrong ? I have made a fresh clean install so it's not the backup. I really think it's related to an iCloud stuff. I will try to disconnect tommorrow from iCloud.

Hi ! I have isolated the problem. If I remove Homekit (delete home configuration), battery drain stops (but I lose all my configuration ! For the moment I don't know if it's about Hue or something else.... But I have 97% battery remaining after 50min SOT. Before, after 50min, I was at 90.

Since 2019 I have made so many tests and I don't understand why Apple did not see this issue !

I got same problem on my iPhone 15 pro Max (iOS 17.4.1)
If I disable iCloud battery life is much better. But what can I do? Something seems to be broken by syncing something with the cloud.
But lots of good features I am missing.

Any idea what we can do?

Any updates ?

Is seems that my iPhone suffers of sneaky battery drain. Not huge but annoying.

I have made lots of tests.

My iPhone drains approximatively the same as other iPhones in these conditions:
- playing video contiously on YouTube
- displaying a webpage continuously
- screen ON and app switching every 10sec (shortcut)

But there is one situation where it seems my phone lose more thant others (but very hard to investigate correctly):
-using my phone with fragmented usage with small use multiple time by hour (safari, weather, sms....)

In this case, I can lose 3 / 4% per hour but with only 10/15min SOT.

Here my new iPhone 16.
90% 7 AM
64% 3 PM
1h58 SOT

What do you think ?
