iPhone 13 Pro battery draining overnight

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.

Well said Yanosh74. There is clearly an issue with the battery; whether it is mainly on the 13 series and/or has more to do with IOS 15.1, I don't know.

Have you reported it to Apple Feedback? (Google Apple Feedback to get to the correct page if you're not sure). Other than calling Apple tech support (and asking the rep to escalate to an engineer), this is the best way to ensure that the problem is highlighted to Apple. The more reports they receive from users in this way, the more likely they are to prioritise taking action to remedy the fault.

FWIW, my battery issues on a new 13 (initially running 15.1 and within a few days after purchase updated to 15.1.1) improved after resetting network settings - however, not to the extent that I am convinced that the battery is running as it should. I don't think the battery life of my 13 over a day's usage is any improvement on the 2.5 year old Xr that I had previously. Given that significantly improved battery life is supposed to be one of the 13's selling points, I would guess that there is still an issue.

Hi,

I also experienced the same issue and contacted apple support. Their suggestion was to get to repair center or have my phone inspected for replacement from my courier. I did not do both.

What I tried is to turn off cellular data during the night (at home when I am already connected to Wifi) and i don't get the issue of 20-30% drain overnight. It was down to typical 3-5%. I think the issue was if the cellular signal strength is not at optimum/maximum, phone keeps on searching even if connected to WiFi resulting to massive battery drains. But i agree that Apple should look into this, although it can easily fixed with software update.

Hi JanRov - this is definitely not what is causing battery drain for me.....I always have cellular data switched off when I can connect to wifi. Seeing as I work mainly from home, this is most of the time, as I am only on wifi at home. At night (bed time), I switch my phone off completely, whether it is charging or not. There is without doubt enough evidence to suggest that there is a real problem with battery drain, I think with the software around 15.1 or maybe even later version(s). I dont think it is necessarily the iPhone 13, as many people have reported the same battery issues with older iPhones, but with the latest IOS software versions installed.

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.

Update: I contacted apple support, spent 2 hours on the phone, was elevated to info being sent to apple engineering. One week later did not hear back. Meanwhile I ordered a replacement phone through my carrier (I had my phone only 2 weeks). I got my new phone and it works perfect. The other was hot all the time and drained the battery with no use every couple of hours. My final summation is that there are some of you out there that may have gotten a bad phone just like I did. Try all the suggested fixes, but don’t dismiss the idea that it just may be your phone. Thanks to all of you for providing ideas of things to try.

obaid292 - If you read through these forums, you will understand that these pages are not monitored/read by Apple.

You need to call Apple tech support in whichever territory you are, they may be able to help. You should also submit feedback on the issues you are experiencing to the official Apple Feedback page (Google Apple feedback, it will bring up the correct page - I would choose "iPhone" as the section under which to submit).

These are the only methods that I am aware of for consumers to bring faults to Apple's attention - the more reports Apple receives, the more likely their engineers are to work on issuing a fix. Good luck.

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???

I did erase and clear all data and reset all settings, however worst part is phone was without SIM card and apps installed. Even in this case it drains so fast that Apple promised 13 series to work though. Tried everything and every single tip. Still it keeps draining!

Hey mmdanut !!

may I know if your issue was resolved? I have been complaining continuously to Apple Support for past 2 weeks as I am facing the same issue from day 1 (bought it 3 weeks back) and support keep saying that your device is perfectly fine which I know its not normal at all.

today they offered me to send a replacement but i am just concerned if that will really fix my issue or not.

I've had a similar issue with my battery draining too fast as well and discovered it was due to having no data allowance but still connected to the 4/5G network. I've had the iPhone 13 Pro since launch date and initially I would notice maybe 2-3% battery drain overnight.

However, in the last month I noticed a change where I was losing over 40% battery over night. It got to the point where I turned things off: notifications, GPS, bluetooth and uninstalling certain apps that I thought might impact battery life to no avail. I even resorted to charging my phone twice a day, not using the phone for a whole day and using automations to put my phone into low power mode over night.

Then I realised, I had used up all 8GB of data plan within the first week of my monthly allowance. As I was mostly at home and connected to WiFi I didn't think having no data with my mobile plan was an issue. Then I turned off mobile data (Settings > Mobile Data > Mobile Data = off) and this instantly fixed my issue. Overnight I only lost 2% battery again. A week later I had my 8GB monthly data back, turned data back on and the battery was completely fine.

So all this time, having ran out of data allowance and still connected to 4G/5G resulted in my phone depleting my battery over 40% over night and depleting during the day.

“During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often.”

I’m surprised by this statement. I did not think there was a way to bypass the battery. I thought you always went through the battery whether you were charging or not.
