iPhone 13 Pro battery draining overnight

everyting you described happened exactly to me.

But the slope of my overnight drain is even more aggressive.I went to sleep with 82%. Woke up with the phone completely turned of.

My guess is the 5G network. But I'll try turning it of tonight.. 😭😞

I am experiencing exactly the same overnight battery drain issue with no apps running on my 13Pro

i am convinced this problem is related to the modem update post modem version 1.60

up until iOS 15.4 there was Zero overnight battery drain.

Apple , please fix this issue.

Thank you for getting back with us, nosleduc. While the articles we sent are intended to educate, they also offer specific steps to take to reduce battery drain, such as disabling Background App Refresh, which could be contributing to the overnight discharge. There have been no detected issues with iOS 15 or any new device that would result in this behavior, so we definitely want to look into the causes for this further.

Please let us know the results of your testing and we'd be happy to continue investigating. Thanks and take care.

hey, nosleduc, how did your story end? did you return it? did you update to 15.1 and noticed a significant improvement? i have similar issue on normal iphone 13 so i am very interested about your experience. bon courage.

I am facing the same issue. Battery consumes lot of charging overnight. My iPhone 7 is consuming less charging than 13 while ideal. And the issue is at night only. During day time it is consuming comparatively less charge. Please guide.

I have been experiencing the same battery decline overnight issue with the iphone 13. I do not charge my phone overnight and it loses on average 30-40% battery. Is there a better solution than to charge the phone continuously?

boa noite

também tenho um iphone 13 PRO MAX e também tenho o mesmo problema com perdas durante a noite de 20% a 30%, já fiz de tudo e nada .

Ontem restaurei-o de fábrica pelo Itunes e fiquei só com as aplicações originais e perdeu 15% com tudo desligado .

agora até desliguei a minha conta icloud e retirei o cartão da operadora para ver quanto perde ,já não sei mais o que fazer.....espero que seja do ios 15.1 pois com o ios 15 estava bom.

obrigado

abraço

but why iPhone 12 Pro Max doesn't drain the battery as fast as iPhone 13 pro in nosleduc's case?

If sth doesn't drain the battery he even wouldn't have to think about overnight charging or not.

Because there are different apps running, different network connections, and, in general, 5G uses more energy than LTE.

Why not just enjoy the phone, rather than think of it as nothing more than a battery gauge?

As I remember he said that he had two phones with the same settings and apps installed.

As an engineer he would like to know the reason for the difference.

Yesterday I turned on airplane mode, just to compare the battery percentage vs only LTE / 5G enabled.

Airplane mode - 2% over the night

LTE / 5G - 5% over the night

I use iPhone 13 Pro.

So it is a normal battery usage during the night without thinking about charging it or not.

Nevertheless your advices about overnight charging with optimised charging enabled are good for battery lifetime, but not everyone can leave the phone plugged to the socket :)

You can also use a wireless charging pad. My wife and I each have one on our night tables. It isn’t as fast as a 20W charger, but, as you’ve got all night to charge it, that doesn’t matter.

But for anyone with serious concerns about extending battery health and preserving data in the event of disaster, overnight charging should be a no-brainer.

Hi Lawrence - I've had my iPhone 13 Pro for about a week to 10 days now, and noticed this battery drain overnight.

• I'm charging it overnight (as you have suggested here) via wireless charging pad
• The battery charges up to about 90% each night then stops charging and declines throughout the rest of the night, despite still being on the wireless charging pad
• You mentioned in a previous post that the wifi antenna disconnects when on standby or otherwise not in use, and that battery drain may be caused by carrier connections.

My question is - specific to this setup, do you not find that this is the case with your phone too? ie it charges to 90% or 95% then stop charging and declines through the night despite being on the wireless charging pad and not in use. How might one prevent this from happening so for example I can wake up in the morning and my phone will be at 95% instead of the 60%-70% that it is when I wake up.

No, my phone charges to 80%, then pauses for several hours at 80%. It then resumes charging and reaches 100% about an hour before I start using the phone. I suspect a problem with your wireless charging pad; try with a cable and see if that makes a difference. Some wireless chargers turn off when the phone stops taking power, and won’t resume until the phone is removed and placed on it again. Good quality chargers don’t do this.

ADDENDUM: This was with a Belkin wireless charger.

I bought a new iPhone 13 two days ago. I had heard that one of the selling points of this new model was improved battery life. The phone I was replacing was an iPhone XR which I've had since July 2019. I am quite shocked to be honest by how quickly the battery is draining on my new iPhone 13 - even in comparison with my 2.5 year old Xr!!

I've read through this thread and all the things that people recommend, I've already done - and the settings were already switched correctly. Furthermore, I have always switched off my phone at night (whilst I sleep) whether it is charging overnight or whether it isn't. So I can see no reason why I should wake up in the morning to find that 10% of the battery level has drained whilst the phone was off. There is clearly a fault with this iPhone battery, or the software that runs the phone.

What do you all think?
