iPhone 12 battery drain overnight

It's not an issue for the vast majority of owners. It is an issue if you haven't isolated the cause on your phone. Waiting for a software update to come is not the best solution for your issue. It may never come.

Now I have updated my phone to iOS 14.3 thinking the issue would be fixed it’s still the same. Turned off mobile data, WiFi and Bluetooth also turned on low power mode battery has drained 22% by the morning and the battery chart doesn’t show anything iPhone 12 is so bad haven’t experienced this kind of issue with any other iPhones before. Why is apple not listening to this issue

i am also experiencing similar problem in my 12pro max. Staring from iphone 7 plus i have used all the models of iphone and the last being used 11pro max but never experienced this problem, this is so frustrating. When in idle battery is draining at almost 4% per hour with wifi and mobile data off

oh my. 403 users having same issues.

i was observing mine and having same. My worst event is when i woke up my phone was completely shutdown. From 30% to 0

i dont have 5g enabled sim yet. There is no app running on the background as i checked.

the only suspect i see here is i got this issue after i paired my apple watch s6. I am still not sure though.

i also read the replies. And darn, why is charging your phone a solution to some? Lol. I sleep most of the time with 50%+ on my batterry and you want me to charge it for 6-8 hrs? I dont think thats a good idea. I suggest you sleep not charging and press the “me too” when you wake up cause im sure you will be having same issue

and yes i believe this is a BUG on OS that needs fixing. FAST

I have the same issue with my iPhone 12. Recently switched to iPhone, using the 18 watt charger of the iPad Pro 2020 to charge it, no open apps, no wifi, no 5G, no anything. My previous phone, Samsung s10 was at 98% and now it’s at 93% after like 10 hours of no use. Meanwhile my iPhone 12 was 88% at 00:40 then when I woke up at 4:44 to get something to drink it was at 81% and now at almost 9 o’clock it was 74%.

I slept all the time and didn’t use the phone. I love the seamless interaction between the iPad and the iPhone, but the battery is very disappointing. I hope it’s a software issue that’ll get fixed.

I mostly only get two bars of reception in my apartment but I don’t see why that should cause it to drain that much and I don’t want to buy a phone to keep it on airplane mode. Lol.

Can’t wait. Also. I restarted my phone now and I’m on WiFi. The percentage didn’t drop at all for like more than an hour. So maybe restarting helped or it just needs to stay connected to WiFi. At least it seems to be a software issue.

Are you sure, and actually is there anyone who already tried the beta version?

I would imagine lots of people have tried the beta version. However, all of them signed a non-disclosure agreement when they signed up for the beta program (yes, even for the public beta) which means they're not allowed to talk about it. The Hosts will remove discussion of beta software if they're posted here in the forums.

I have the same problem battery is draining over night but i dont have that problem during day i charge the phone at 6:00 in the morning and by 6:00 in the afternoon when i get back from work i stil have like 70% battery left and 2:30 -3 houres off screen on

Same story with my iPhone 12 Pro I got a few weeks ago. The battery is draining overnight on standby with all the apps shut. My habits didn’t change and my old iPhone 11 Pro would use just 1-3% overnight, the new iPhone 12 Pro is using 20-40% with 0 activity and I often find my iPhone 12 Pro dead in the morning.

Regarding battery drain overnight. I have found that if I reboot my phone before I go to bed I get no battery drain at all. Note. It is still on but I don't use it after I restart it.

I was losing 20%+ per night

This is not very practical but might give some clues as to why it happens

Same for me too. I usually sleep by 11pm and wake up by 7am and from 12 to 6 there is no information for battery usage and i lose around 15-20%. But if i turn in aeroplane mode it reduces to 2-3%. Try it if you are okay with that. Aeroplane mode on and wifi on.

same problem - bought iphone 12 yesterday and lost 9% during sleep with no app running in background, no fb nothing. extremely disappointed and waste of money finally. my android worked way better with an incomparable battery performance.

The same thing is happening with me. I just bought iPhone 12 a week before and charging it with genuine Apple 20 watt usb-type c charger. I usually charge my cellphone before sleeping up to 100%. and unplug it before sleeping and it drains almost between 10 to 12% in a night period of 7 to 8 hours even I used it in power saving mode and internet connection via wifi instead of cellular data.

I'm also having an iphone 6 with me at 83 percent of battery health. even iphone 6 is very good in battery consumption in night time as compare to iphone 12. it drains 8 to 10 percent in a night after having 81% of battery health.

Actually it depends on your charging percentage. if your iPhone is charged 100 percent then it may reduce battery only 5 to 6 percent because iPhone 1st discharge from 100 to 99 percent takes some extra duration as compare to remaining 99 percent. if you really want to check battery consumption then I suggest you to check with remaining 90% and so on.
