iPhone 12 battery drain overnight

I have the 12 Pro Max and am seeing this issue too!

I significant drain during the night, I just woke up and dropped about 20%, that is way to much!

No app usage at all during the night except for the Exposure Notifications.

Charging during the night is not the solution nor what I want. I bought the Max so that I could go days without a recharge; this is preventing me from doing that.

And I agree with other people that if it's doing this during the night it must also be doing this during the day.

I have 5g mode turned off by the way. I have no use for it (I wish it wasn't on the phone to be honoust). So I'm sporting 2x4G as I was doing with my Xs Max.

My iphone 12pro max 128 is just 10 days old and I am facing really bad battery drain overnight. I had almost 90% left for couple of days before I had gone to sleep and woke up with a remaining battery of around 65%. But white mobile data connected then drain only 10-15% .The battery chart has nothing for these hours. And moreover my mail push is set to manual and I had turned off wifi, bluetooth, location and mobile data. Is there something I can do to stop this?

Omg finally i’m not the only one facing that problem. Here is the same problem, i turn of wifi, Bluetooth, location services, siri, background app refresh and nothing is running in background. Even that I charge my iPhone 12 to 100% battery before i sleep. Then i removed the charger, but when i woke up, it’s like 88% sometimes 90%. What’s going on with some of iPhone 12 ? I’m hoping next update to fix that problem.

Hi to All!

I have just faced with a really bad battery life during last night with my iPhone 12pro. Fully charged in the evening then without using it during night, in the morning I saw the battery is on the level of 56%. It seems to me an extremely huge problem and thinking to take it to apple service. Just to show you I attach a photo about it so you can see that there was no activity during the night but the battery was going down in a beautiful way like skiing from a hill.

Do you think I should take it to the service or wait for a new iOS update that will fix it?

It was connected to WiFi of course, just like all my previous iPhone mobiles. I would not accept to change my previous trends to have a normal battery life...meaning turn off something, close some app or play with internet connection...this phone is a brand new model and it should not bring such negative feelings in me

Do you really believe that it is useful for a new generation lithium battery to charge it over the whole night every day? I don’t think so...for this type of battery the best level to keep it is between 20-80%, not good to let to go to 0 or to charge up to 100%

Yes I do think its useful to charge your battery overnight while you sleep. All night. EVERY night.

I traded my iPhone 11 Pro Max which was charged EVERY night ALL night long. In 13 months, the Battery health on the phone was 100%.

Ok guys, so here is the answer to everybody who has battery problems during the night with iPhone 12 models: charge it all night long so you will not face this problem again :)

I think this conversation went far from the original question that is a very serious issue for the manufacturer and many users are waiting for the solution.

The question is why new models are dramatically loosing from battery life during the night when they are not used at all?

Guess the points coming up here are a solution to charge the phone overnight so that one doesnt see the discharge free fall thats happening in the idle state; in my opinion, thats not a solution. The root cause still remains and thats for Apple to address. I'm pretty much satisfied with the backup that I'm getting except for the drain over night; if this is addressed, the battery backup would be above satisfactory level.

Plus if apple support is pathetic, all they do is hit and trial to see if something works. Its for apple to come up as a solution in their upcoming iOS 14.3 update so that this is taken care. Hope Apple is listening !!!

OK.....You can believe what you want. I'm suggesting you do some troubleshooting. You can sit and wait for a mythical solution from Apple, which MAY or MAY NOT ever come. Your choice.

I'm not going to continue this with you at this time.

Hey! If you don’t have this issue at all so why you are taking part in this topic forum? Why are you trying to push your “solution” to others if you don’t have this issue therefore you don’t have an experience in it?

This is a technical support forum. If the only people who were allowed to post were the ones with the problem, that would be a lot like saying that the only doctor who could treat your illness was the one who currently had the identical illness. While some of us may not have the exact experience you are having, we have done a lot of trouble shooting. We have read a lot of threads, watched solutions unfold.

this is the post that should be written by someone who has no experience in the actual issue, thanks. But you can tell your suggestion once then everybody will make their own decision if follow it or not, but it’s useless to repeat or push something. I mean it also for your opinion about waiting for apple to solve it by an update, cause it happened that an update fixed a problem. Furthermore in my opinion an issue is general if more than 100 users face with it (so as in this topic) because general issue does not mean that all users suffer from it!

I don’t agree. If someone who read about many troubleshootings or has some experience in past issues should not allow him to just comment on all new issues without any experience/knowledge about the issue itself. Especially if we are here in a technical support forum as you wrote where we are looking for an answer or solution and not an opinion on why we are waiting for apple to solve it....because till now this looks the only solution.

You are allowed to have your opinion. You are not, however, allowed to dictate who does or does not post.

Suggestions things to do have been given. Some of the people posting in this thread seem to prefer insisting those suggestions are not valid troubleshooting steps and that the only thing to do is to wait for an update. That is foolish. It is more likely that the problem can be solved by standard troubleshooting and that an update designed to solve the problem will not be forthcoming. You are, however, free to wait.
