iPhone 15 Pro Max Heating & Battery Draining Fast

Ofcourse it's just with some phones. If all phones were bad it would be all over the news. Also, if you read this thread, you'll see people (like me) have had their phones replaced and all is fine and dandy since. So, yes, it probably is just a bad batch.

Just wanted to register to say the same thing. A one hour cellular call drains 17%, I've only had the phone a couple of weeks. Most wifi activity (streaming vids etc) seems fine, but making a regular call drains so much. I sometimes make several long calls in a day, so just three would drain over half of my battery.

I have been with my phone for only two days and it’s heartbreaking that the battery drains so fast. I have been trying to figure out what they meant when they say it’s battery last longer than any other phone. I am so disappointed. On top of that the phone overheats when charging.

I feel this purchase is a complete waste of my hard earned money!

You've had it two days. Give it a couple more. Especially at first things need to 'settle in', stuff is being (re)indexed in the background etc. If it's still bad in a couple of days, just return it to Apple and have it exchanged. By now it's pretty obvious this isn't a "every iPhone 15 model is affected" issue. There's just some duds, a bad (few) batch(es). It happens. I know first had (read this thread) that finally getting your brand spanking new expensive gadget and then having it not work perfectly sucks. But, trust me, it's no "complete waste of [your] hard earned money". If it's still bad in a few days, have Apple swap it.

We just bought an iPhone 15 pro max and having the same issues.

Phone is getting hot and battery draining so fast.

We have an iPhone 13 pro max max and no problems like this.

I hope this is sorted out soon.

It shouldn't be like this...

It is still worst experience I have ever faced regarding battery backups of iPhone 15 pro max. I used to be able to use my 2 year old Pro Max 13 for 2 days EASY before having to charge (over 48 hours)

This is additional information.

I checked the battery usage statistics during the 55 minute call via Settings then Battery.

71% correspond to "Home and lock screen" and 29% to "Phone".

Maybe the Always on display has something to do with it?

Same here just normal usage and battery percentage drop by 1% every 2,3 minutes

I'll turn my off with a full battery and go to bed. Yet, when I turn it on in the morning, the battery is at 42-50% despite not being on. This has happened 2 out of 3 nights

My iPhone, 15 ProMax battery drains rapidly, even when not in use. It went from fully charged to 60% in two hours. I only picked it up twice to send quick text messages.

I noticed the same issue with the 15 pro I just bought. Comparing with my 11 pro max. The 15 pro is draining x2 faster!!! This is so annoying. Now I have to carrying 2 phones everywhere. :(

Got the same problem. Loosing 2 - 3% while scrolling on Twitter/X for 5 minutes. Or using my phone for the Crunchyroll App to my TV. Every episode (20 minutes) there are about 5% of battery loss.

3 of my mates returned their iPhones 15 pro max today as they have the same issue with the battery.

You all can return your phones within 14 days from purchase even if used.
