iPhone 13 Pro battery draining overnight

I also have bought 13 Pro max 2 week ago and there was an update of IOS 15.1 last week and since I am seeing a battery draining, I have all my app refresh turned off, dark mode is on and always made sure phone charges 80/85 percent. But till I hed to charge it 3 times since yesterday morning because every time it gets about 50% battery consumed in couple of hours, while I am not even watching Videos. I thought will observe few days more but saw the issue here raised so thought to add my problem too.

That depends on what you were doing. The only thing that uses energy from the battery is apps that you are using. 25% in 6 hours works out to about 50% a daytime, which is probably slightly better than most users see. Typically, if you charge a phone overnight (and you should), it will start the day at 100% and end the day between 20% and 40%. So your usage is a bit better than average.

boas

tenho um Iphone 13 Pro Max e gostava de saber se é normal quando no écran diz que tem 100% de carga mas diz ao carregar .....

o meu com tudo desligado sem aplicações em segundo plano sem gps ligado nem encontrar Iphone e siri desligada e copia de segurança desligada, durante a noite gasta-me 20% de carga sem presença de aplicações a trabalhar.

The iPhone will stop charging when it reaches 100%. However, the icon will display the charging symbol to show that it is still connected and the external power source is providing power to run the phone. That is why charging overnight extends the life of the battery. Once the battery reaches 100% all energy used by the phone comes from the charger, and not the battery, so the battery can "rest".

O iPhone irá parar de carregar quando atingir 100%. No entanto, o ícone exibirá o símbolo de carregamento para mostrar que ainda está conectado e que a fonte de alimentação externa está fornecendo energia para ligar o telefone. É por isso que o carregamento durante a noite prolonga a vida útil da bateria. Assim que a bateria atinge 100%, toda a energia consumida pelo telefone vem do carregador, e não da bateria, para que a bateria possa "descansar".

"Further, if you DON’T charge overnight all overnight data communications uses cellular data, because Wi-Fi is turned off when the phone is locked and not plugged in. "

Lawrence, out of curiosity why do you state that WiFi is turned off when the phone is locked and on battery power? Not only does that make no sense from an engineering standpoint, but it is also not supported by my simple experimentation. My router has a status page that shows the online / offline status of every device that it has seen. If I manually turn WiFi off, the iPhone shows a transition from ONLINE to OFFLINE. If I leave WiFi on and lock the phone, the iPhone continues to show it is ONLINE. ??????

"I state it because it is a fact. Wi-Fi uses energy continuously when connected, unlike cellular, which only uses energy when actually transferring data. It makes perfect sense from an engineering standpoint; if Wi-Fi remained connected battery drain would be REALLY unacceptable. "

Hmmmm.... I understand what you are saying. Maybe we are just in disagreement over semantics? I have not tried to ping my phone.... maybe it does indeed stop responding to pings after a while. But something the phone (iPhone 13) is doing makes the router think it is still connected since it shows online even when locked and sleeping. If I manually turn WiFi off, the router immediately shows the phone as "offline".

Or is it possible that something is misconfigured and it actually should NOT show as "online" when it is sleeping? I activate battery saver at night and my standby drain is about 0.4%/hour in battery save mode (no background refresh and no mail fetches). There was one night when the phone was new (about a week ago) where I saw about 0.1%/hour but that was only one night and I have not seen the standby drain that low since.

From what I have read, my 0.4%/hr is pretty reasonable. I found this thread while trying to maximize my standby time and saw your statement that WiFi is off during standby, which got me questioning and thinking.

I don’t know why your router works that way. My router shows all devices that have active leases, whether they are connected or not, and they remain on the list when I turn off Wi-Fi on the device. The only way you can no for sure is to try the ping test.

Shutting down the way you describe is one way to reduce battery drain, at the expense of convenience. But if you want the battery to last longer you should still charge overnight, and not jump through hoops to save the battery. An iPhone is a useful device, not just a battery monitor. More than likely the battery will last at least as long as you are going to own the phone or longer, and even if it doesn’t it is inexpensive and quick to have Apple replace the battery in an Apple store while you wait.

My battery profile looks exactly the same. I have turned off background refresh, restarted, forced restart, wiped my phone clean and reinstalled from backup and then did that again from a backup further back. I also turned off 5g and went back to LTE. None of these “fixes” worked. The phone is still doing the same thing. Did anyone find a fix that works?

Laurence, wake up on the wrong side of the bed this morning? I know how to charge a phone and have been charging it correctly for years. I have never had a problem like this until I got the 13pro. I would like to use my phone, but the battery drains so quickly that I have to charge it multiple times a day. With my old 11 I needed to charge it once a day and usually by nighttime it was still above 50%. I stated all the remedies I have tried and it is still the same issue. It has nothing to do with charging. If you have no constructive suggestions just move on to the next forum where you are probably equally snarky.

Hi Doctor Zhivago. Here is the screenshot of my old iPhone 8 plus (on 84% battery Health, if i may add). Data/WiFi/Bluetooth for this phone is turned off since i am

ot using it anymore but the phone is Turned On. As shown battery drain is only 48% from Last Saturday which is almost 96hrs already. Phone is on the latest ios version.

Mario49,

Why the crap do you constantly “answer” questions that have a lot of detail with links to subject related “Q&A” posts by apple that clearly won’t help at all based off of the details already provided?

My guess is you are either:

A: A somewhat advanced spambot that looks for keywords then posts a generic comment linking any unhelpful Q&A pages that have the same keywords.

B: Someone who cares more about how many questions they “answered” than actually helping the person asking the question.

Hello! I have the same problem with my 13 pro max, the main difference is that some nights it’s perfectly fine, 3-4 % drop, other nights it’s over 25% which i think is not normal. I am not doing anything different from one night to another, i’m placing the phone in the exact same place, so i don’t see why it would be because of the signal. I’ll try to reset everything and see what happens after that.

Yanosh74 - interesting. I tried two of the fixes highlighted by users on this forum 2 weeks ago and my battery life definitely improved, to the extent that I am no longer fussing over it. However, it is not as good I would expect an iPhone 13 to be, given how the 'considerably improved battery life' was one of the advertised features of the 'phone - and comparing it to my 2.5 year old iPhone XR that this phone replaced.

I also find that my 13 gets hot....but only for the rapid charging that takes place in the first 20 minutes or so of plugging it in to the mains. The final stage of charging doesnt seem to make the 'phone hot. Also it doesn't get hot for any other reason - in other words, it's working fairly normally.

All I can conclude from reading all these different users' comments is that there seems to be a variety of problems, there is not much consistency in what is being reported....other than poor battery life! Let's hope Apple are working on fixes.

I have the same problem of fast draining but during the day while using the phone (IPhone 13 pro). I leave the phone overnight for charging. I will try what you did to see whether it is going to drop the charge overnight without using the phone. Called Apple support about this; the call lasted 33 min, including waiting time (about 5 min) and the battery charge dropped from 28% to 19%. Clearly, something not right gaining on!

Hi nosleduc

what is the solution then, I mean did you find the reason?

recently I bought iPhone 13 and it drains for 40% during night without apps installed and SIM card, at the same time I have iPhone 11 with 86% battery health, unlike iPhone 13 it drains for 5% during night.

Dear Apple, do we really need to return all 13s???
