Why is my iPhone 16 Pro Max battery draining so fast?

Yeah, my four year old 12 pro max has significantly longer battery life than the 16 pro. I realize it may be a smaller battery, but it is a week old… actually, looked it up and the battery size is almost the same. Mr. Buffett must have had one of these for a week. Explains a lot. This is an Intel level failure.

7 am to 1:40 pm

Light browsing, 1 hr call; went from 100% to 28% on 16 pro

Similar work on 13 pro - never saw the battery draining this fast.

Will try the if those Max methods would work on 16 pro too.

It isn’t just after the update. I didn’t transfer apps and mine barely lasts half a day before I have to charge it. This is a bunch of you know what and especially when you pay 1300.00 for a new phone. I’m so disappointed in apple. Seems like everyone is experiencing this and apple …. Crickets on a known problem. Clearly known as you can tell from just this one forum

I’ve had similar issues with my 16 pro max battery dropping constantly. Another strange thing I noticed is that the MagSafe charging slows down after 59% and stays at 62% for about 45 minutes. This happens only with MagSafe and not usb-c. Anyway went to Apple Store they ran some diagnostics and replaced my phone.

The new one is no different. The battery charging is slow when using MagSafe charger (30 watt adapter) and now the charging stays at 68% for about 45 minutes. I’m not sure what’s happening here!!

Same! And the whole reason I traded in my 13 was that the battery wouldn't last a full day any more (I'd had it for 2+ years). I know the camera is great on the 16 Pro, but other than that, I can't see any real improvements...

My new iPhone 16 pro is needing recharge after only 7 hours and only light and intermittent use. I thought my older battery on the 13 pro was getting bad but way better than this 4 day old iPhone 16 Pro 😖

I am having the same issue with battery draining, I own a Tesla and I went to get into the car and it would not open, fortunately, I always carry the key card in my wallet.

I have seen this issue on new iPhone releases in the past and after a while I expect Apple will release an update to fix the issue.

Yep. Wishing I had kept my 13 pro. Can't believe how fast my 16 pro drains the battery and I'm barely using it. Thought this was supposed to be much better battery life. This is not what I thought I was paying for.

I just received it 3 days ago, I have now iPhone 16 pro, and I noticed that the battery must have some issues! It’s absurd how can go down in half an hour even if you don’t use it a lot like constantly. Especially I was quite surprised to see it on the morning it dropped down to 5% after last night charge? I have no idea but my iPhone 14 pro in the begjnng lasted much longer. When I got it, I could say that battery lasted definitely log, especially not used no matter if WiFi is on or Bluetooth orbiter stuff in background, I feel like we l had better batteries in the previous models😅 I wonder what they did that made it give up on the first day? It feels like even iPhone 16 pro came exhausted in the box lmao.

But let’s say that even my keyboard has problems I reset it, and I speak in English and I use predictive text so I can write faster, sometimes it doesn’t even seem knowing the worlds, I’m doing to change English with other English, same thing with other languages on my phones that’s one of the weirdest things that happened to me with iOS lol

I hope that after one month our battery percent doesn’t drop under 50%’😭😟

now is 100% but dropping so fast, never encountered that fast tho lol Like j read the comments and someone said they used safari and form 100% went to 80% for half and hour, yeah j put Spotify maybe and just close it, for half and hour or less depends if j want to explore more songs. Still don’t bave that many background apps that may affect it.. battery down with 20% less😒

i hope there might find a solution, this phone is great but something went wrong with thej life of the battery. At first I thought oh I must be maybe the only one, but as I saw it on the community I’m like wow we’re literally a a lot ! I’m glad tho, I think that until now Apple might be already aware of the batteries that are not lasting even half the hours they mentioned 🥲😅

I noticed this too! Also idk if it’s normal even when I use if for short time, it gets warm and even hot at touch. Does it happen to anyone too? I checked all apps that may be possible reason and other things but none, as j have deleted already the unused. Thjs. Happened since the first day it arrived, so I found it quite weird. Feels like pure unluck when it becomes like burning warm and no battery lasting life, I might have joked this phone was put already exhausted in the. Box, so it shuts down lol but for real it was released almost month ago, I find it too early for us all to be having these problems but yet we do🥹

Not at all, my phone even gets hot like it’s been overloaded with stuff and I’m just on safari. I guess I’ll report that in any case to check out why it gets heated🥹

I haven’t felt any improvement on the battery I hope it they do another one maybe

it drops down just like as before, but maybe others might have sen improvement? I hope it gets improved 🤞

I have the same issue. Really regretting switching from my iPhone 15 Pro Max to the iPhone 16 Pro Max. The iPhone 15 Pro Max is probably the best battery experience I have ever had in a phone. I feel more than disappointed.

I charged it up to a full 100% yesterday in an attempt to calibrate the battery and it seemed to have done the trick…

50% discharge in the last 24 hours which seems reasonable regarding what I did with the phone.

You shouldn’t have to set it up as a new one… I’m sick of apple and there excuses my iPhone 13 Pro Max and 14 pro max lasted waaaaay longer… I’m about to call AT&T to figure something out I don’t want this anymore and I want my old phone back

That's certainly your prerogative, but I took a flight last week with my 16 PM and over a movie played over a two hour flight streaming via the plane's Wi-Fi, the battery used was three percent, from 100% down to 97%.

Battery drain on a phone call will vary depending upon the reception in your area.
