Battery draining fast on iPhone 15 Pro

Second day with the phone and had to charge it twice today and it’s back down to 19% after normal use…No apps running on background or extended use, battery health at 100% 🤷🏻‍♂️🤦🏻‍♂️

When you first activate it or do an iOS update, the iPhone always tend to drain the battery faster and this is due to the background process iOS does to optimize, including, but not limited to, syncing with iCloud, re-indexing your file system, photos, etc. (for faster search). This is normal and usually ends quickly, depending on the amount of data you have - the more data, the longer it takes.

I bought my first iPhone 15 pro max 2 weeks ago and the battery was dying ridiculously fast. I figure it was just the phone and turned it in to get a new one and same thing. This issue is BS and needs to be fixed. These phones are so expensive for them not to last the whole day. I don’t even use my phone. It has gone down 5% just being in my pocket while I am at work.

My wife and I both have the new iPhone 15 a couple months ago. My wife’s battery 100% full charge in the morning drains to about 10% within 8-10 hours. My phone on the other hand holds charge most of the day and by 10pm I may only be down to 60%. Is there a setting or something running in the background that’s draining her battery much faster than mine?

I can so relate. It’s nothing but regret for me. My 14 pro max plus won’t last the night (5 hours) on a full charge unless I use my earbuds. It gets blazing hot whether I use the charger or not. I went in, as well, and heard the same thing. (If you compare the earbud nights (lost 6%) to none (dies in 5 hours with full charge.)


Don't get me started on the camera.

I am right there with you. I have never felt such regret with an iPhone purchase. my XR could last all night on a 100% charge, and maybe 30% or so. My 14 Pro Max will not last the night with a 100% charge. And we’re talking five hours because I don’t sleep that much. Plus, it gets very hot in the meantime. Last night, I used my earbuds, and it only used 6%. If I could find out what the connection is, maybe I could fix it. The thing is, it shouldn’t be like that. Everyone has all of these solutions like turning off IG, closing your Facebook apps, or whatever. I never did that before and we shouldn’t have to do that with a newer phone. I took it in as well. They told me there was nothing wrong with it.

Don’t get me started on the camera. That one really upsets me and it has ruined a lot of events for me.

As I read these comments (I have a 14 Pro Max. Don’t consider downgrading to this one) and I think to myself as I read all your well-meaning advice: We shouldn’t have to be jumping through hoops like this. We have we been told to… remove social media apps. Turn off 5G. (Isn’t that’s supposed to be a feature for us to enjoy?) Etc etc. We are all here desperately trying to find answers, instead of going to the source. But the source isn’t listening. I’ve always been an Apple fan girl. Since the 4. I’ve never considered switching brands, but I am now and that’s telling. I think I’m equally bummed by the camera performance, but that’s another story. As soon as I’m eligible for a trade, I’m done. And this isn’t me trying to strong arm Apple. I truly mean it. I’ve been late getting up because my fully charged phone died in the middle of the night. I missed documenting any portion of a one chance concert. That’s one that really got to me. Here I am with a handful of 100% regret.

I’m having the same issue!

I only bought a new phone because my previous 11 pro was dying by 1-2pm and now my brand new, 3 day old iphone 15 pro is dying by NOON! My husband has the 14 pro max and his lasts literally 2 days. He wakes up at 5am, blasts youtube videos, plays phone games, uses instagram etc and by bed time it’s about half battery. So why is the 15 draining SO quickly?!?!?! I did turn off the always-on lock screen option, but didn’t seem to help much. I am not home all day to stay glued to a charger, nor is this what I expect for $1200.
