iPhone 15 Pro Battery Life

Bought my 15 pro 3 days ago. Battery life is awful. My 2 years old iPhone 13 can hold the 1,5 days, using phone throughout the day. But this, I don’t know. I was at apple store yesterday, they did fast battery diagnostic, from 6.00-22.00 if your screen time 3h- phone is dead. It’s not normal, now i need to give my phone to apple repair service for more diagnostics. I don’t think that for 1,2k phone it’s ok and i hope i will get new phone with normal battery.

I got 6 hrs of sceeen time and have about 10% left - should be concerned? I also upgraded to a iP15 Pro from an iP 11 Pro

Let’s define “overheating”. If an iPhone overheats it shuts down so it can’t be used, and displays a message saying it must cool down before it can be turned on, and it will probably be unusable for an hour or so. If you are seeing this it is a hardware problem and you should contact Apple support: 

• Click on “Support” at the top of this page
• Go to Contact Official Apple Support

Note that both of the above have options to receive a callback or chat

If you are not seeing this your phone has not overheated. However, if you fast charge your phone may pause charging at 80% and display a message saying that charging has paused, and will resume when the phone cools down. This is NOT overheating, and is normal when fast charging. It also won’t prevent you from using any app you have on your phone.

Also, some apps that use a lot of energy or that use cellular data rather than Wi-Fi can cause the phone to run warmer.

If you just bought the phone and you moved all your data over to it, it is working hard to index billions of bytes of data, which can take a few days, depending on how much data you have to index. And since it's a new phone, you're likely using it to see how everything works at the same time. You need to give the phone a few days to settle down and let the indexing process complete.

I kinda sorta wish Apple hadn't added that notification. Like Battery Health, it seems more to cause anxiety than to solve actual problems.

Yes, it just paused and didn’t say why. It was much easier to answer “why did my phone stop at 80%” than it is to explain that dialog. But I also think they were oversharing with the Maximum Capacity display.

But i was on vacation this weekend and charged phone through my Mac and it lasts at least 36h after charging. I don’t know what should i do now. Seems like they make a phone what only you can charge from you pc for a longer use.

The phone doesn't know where the power is coming from. Electricity is electricity. It sounds more like there was a problem with the adapter you've been using. It's possible you were using one that didn't pull enough power or was defective. Newer iPhones require more powerful adapters.

I got my iPhone 15 Pro on launch day, and I don't think I've ever charged it from my computer. This is the adapter I've been using:

Anker 20 Watt

Note that it is a 20 Watt adapter.

If you bought the phone 3 days ago from Apple, you don't need to give it to Apple Repair. You just need to return it and get a different one.

One of my regrets was getting the iPhone 15 Pro. The battery life is by far the worst, and my iPhone 11 still lasts all day compared to the 15 (keep in mind my 11 is at 84% battery capacity and the 15 is at 99%). I spent over $1,000 on a cell phone, and every day when it reaches 20% by 3 PM with minimal use, I regret ever wasting my money.

I switched from an iPhone 11 Pro that had a fairly new battery (about 95%) to the iPhone 15 Pro. I have been blown away by how great the battery life is on my iPhone 15 Pro. I like to play games on my phone late in the evening to wind down. I would often have to plug my 11 Pro in to do this. The iPhone 15 Pro almost always has 30-40% remaining at 11 pm.

I'd say that the battery drain is normal when using as it will get you around 8 hours of screen on time.

What is causing you to think it's overheating while charging?

Maybe it works if you live in US or somewhere else. In my country i should go through several steps to prove that they sold me broken phone. But i was on vacation this weekend and charged phone through my Mac and it lasts at least 36h after charging. I don’t know what should i do now. Seems like they make a phone what only you can charge from you pc for a longer use.

Hey, just started to charging directly from my Mac and seems it solves the problem. So no, didn’t get a new phone. It’s been 3 months for now, i think it is really issue with adapter that you use. Try to use original one. Didn’t buy mine still because there is no need. Will buy mine in summer when i will start travelling then will see if there is a really issue with adapter or the phone.

I can’t Imagine, wow. I got a 15 pro and I’ve been using it and 100% last me an average of 10 hours constant use. And the worst part is that I’ve been spiraling thinking that there may be something wrong with my phone, but after reading all this answers I see that my phone is okay, and that a problem would exist if 100% just lasted 4 - 5 hours. I hope you get a new phone
