Battery life destroyed since installing apple watch

[tonmischa]

Watch is no longer in settings as I have removed the app.

1. Just removing the app might not have automatically deleted the connection between Watch and Phone.
Please try again by following these steps to the letter:
Unpair and erase your Apple Watch
(You might have to re-install the Watch app first.)

2. You did not answer this important question:

How many tabs do you have open in Safari including in Private Browsing? Your Safar is using awfully a lot of battery it seems.

Try to close all Safari Tabs. Then try to "force close" Safari.

3. When did you restart your iPhone last?

I bought the phone reconditioned but direct from apple so I think its got an apple battery. No idea how to check though. Its showing as 100% health.

Battery health percentage wouldn't show if it's not an original Apple battery.

So you're good.

And I don't know why it would drain this fast.

That is if it is in fact draining faster than a 13 mini on iOS 17 drains battery..?

I'm not trying to derail this post. But are you completely sure that this level of drain isn't the norm for 13 mini on your current iOS version?

Anecdotally, and from a few comments in here, it appears that iPhone 13 mini doesn't just drain faster than the 6.1" iPhone 13 because it has a smaller battery. Even when taking the fewer mAhs out of the equation, 13 mini still drains faster than the 6.1" 13 because heat management is dramatically worse.

have you tried the old advice of draining it all the way down to 0% and then charging up to 100% without interruption. that was supposed to recalibrate it

The recalibration sequence doesn't work with newer iPhones.

Battery calibration happens automatically on 13 and 13 mini. It wouldn't fix or change anything to go through the steps that you mentioned.

to the OP, if you’re open to it doing a “Reset All Settings” will most likely help and solve your issue. This will allow you to keep all your apps and data but reset the plist file which might have a bad or corrupt setting.

If that doesn’t solve it then you’ll want a complete restore or DFU if you know how to do that.

But why is it still doing it now even though I’ve disconnected the watch and deleted the watch app? It’s behaving like the watch is still connected. Can anyone offer any insight? Would reinstalling help?

User has virtually no control Of what process is running behind iOS. No, I don’t mean apps, I mean system processes. There could be a bug surfacing that a rouge process keeps running automatically and hogging the power while user can’t really do anything to kill it And fix the issue.

Sorry, I'm not sure you understand. The watch is no longer connected to my phone and the apple watch app has been deleted. So surely they should no longer be trying to talk to each other?

I am 100% sure this is due to the watch being connected previously, as it started immediately when the watch was connected and has carried on since, but what else can I check to remove other than disconnecting the watch and removing the app?

Reset the phone, as in, factory reset it and see what happens.
Meaning, no iCloud or any other backup should be reinstalled unless it was from before paring the watch to the phone.
Make as new and report back.

What apps are using the biggest percentages of the battery?

What apps are using the biggest percentages of the battery?

I believe anything from Google (YouTube included), Facebook, Messenger and Instagram are still memory and battery hogs. Didn’t know about Snapchat, anyway here is what mine looks like:

Upd: sorry I haven’t thought that it was addressed to OP. Anyway just for the sake of comparison let it be there since I also have “tiny battery” iPhone
