iPhone 15 Pro My iPhone used to be the standby king

[Hyloba]

Androids were notoriously bad with battery standby when not using the phone at night. My first iphone 6s was king at this. Barely lost a percentage or two at night. Now with my 15 pro I seem to regularly lose 10% or more, with low power mode on. There are no apps which cause the drain if I look at the battery graph, it just loses 10%.

Anyone know what might give me my kingly standby time back?

Try putting it in airplane mode as well as low power mode and see if it helps

I simply don’t understand why should we even try all these unnecessary steps when the $1000+ devices ought to function normally right out of the box?

Indexing? Give it a few weeks ? Then months ? Then iPhone 16 releases and the “still indexing” excuses repeats into&” iPhone 17? Then 18?

This is coming from a very angry ip15pm user(me) who regretted buying , as the battery drain exactly matches my 11 pro max that just had Apple Original replacement. EXACT DRAIN, I REPEAT AGAIN.

Plug it in at night?

Overall, nothing. iOS does a lot more in the background now than it used to. You can improve it through settings, but with matching settings, it won’t match pre-iOS 12 levels.

I have an iPhone Xʀ on iOS 12, and my 6s on iOS 10 is infinitely better.

iPads have suffered the same impact. Sadly, it’s a byproduct of features. Like I said, you may improve it through tweaking settings, but forget about iOS 10-like standby numbers.

Yeah my 15PM is not as good as previous iPhones for sure. Kind of sucks.

Well my 15PM has shortcuts to turn on airplane mode and low power mode at midnight then switches them off at 8AM and I lose 1% (occasionally) or nothing (most of the time) over night. I charged my phone to 80% then take it off the charger at midnight and it still reads 80% when I wake up.. Before I started doing that (my iPhone X) I would lose maybe 4-5% overnight, definitely not 10%.. Everybody's setup and apps are different so possibly you have apps that run in the background without you knowing and cause draining issues

It’s a fresh reset of everything…. I’m doing the bare minimum…

I’ve tested a bit further with my phone and I have been able to get amazing standby times again, with losses of 2-3% per night. All I had to do was turn of cellular.

I wonder why cellular is such a battery drain though, it wasn’t with my iphone 6s. But I do have noticed not too stellar connection with the 15 pro, don’t know why that is.

How’s this any better of a fix than turning on Airplane Mode? You shouldn’t have that much of a drain overnight even if you’re on cellular. Maybe you can post an image of your battery life graph so we can help.

Well yes, depends on what you call airplane mode. Wifi and bluetooth were still on, so the phone could update and do background processes, just cellular signal was off. Don’t know what a graph can help, at night there is nothing it can show, during the day it’s my most used apps, mostly safari.

I lose about 2 to 3% a night without turning anything off.

Coming from a 10 month old iPhone 13 (regular, not Pro), I've noticed this as well. Significant differences in standby drain. Same carrier on both, same settings (restored from the latest backup of the 13). I've actually had two 15p's since release, and both behaved the same.

I'm leaning towards the processor or radio/antenna (or both...). After almost two weeks of use on both (i.e. plenty of time to "index") I'm averaging 1-2 hours less on the 15 Pro than my 13, and worse on days when I'm using the phone more (especially navigation) - and haven't changed my day to day behavior at all.

There are things I like about the 15p over the 13, but for me, this is enough to be done with it and maybe see if some updates will help it out and maybe try it again in a few months. Somehow my 13 still has 100% battery health after 10 months, anyway. I don't really want to pay that much for a phone that will cause me to have to be more concerned about charging it. 🤷‍♂️

Edit: Also, I don't use AOD at all, I have it turned off.
