Battery draining fast on iPhone 15 Pro

My first two days of owning an iPhone 15 pro: I plugged in my phone as normal before bed and it was not fully charged by the morning. I made a phone call, checked emails, and by lunch my phone was at 11%.

I plugged it in again and it charged up to 13% then I checked it again after an hour and it was back to 11%. I had to use a wireless charger for three hours to get my phone charged to 92%.

Tomorrow I’m taking my phone in because this is unacceptable for Apple to be sending out “new” phones with ZERO battery capability. Beware before you buy! Such an expensive product only to immediately have issues- big disappointment.

I just got my iPhone 15 directly from the Apple Store shipped to my home on January 2, immediately upon set up, my battery started draining faster than my old iPhone 11 that just died that had a worn out battery. I have background app refresh, turned off, and I've proceeded to remove every app that I thought might be draining the battery, but I'm really disappointed because this phone is advertised as longer battery life. I've had iPhones back to the iPhone three and this is the worst battery life I've ever had for a $1000 device that's brand new. Battery capacity shows 100%. Just contacted Apple support and they act as if they knew nothing about this. I know that's not true because I've seen lots of post like this one right here in October .

Supports gave my only solution is return this $1000 device that still in the 14 day purchase return period.

This does not solve my issue and also just exchanging this device for another brand new iPhone 15 with the same battery drain issues is not going to help me. Is there anyone out there is having great experience with their iPhone, 15 battery life. is there anyone out there? Who's made any headway with Apple support on a solution for this battery drain issue for their latest and greatest device?

you're right it is an amazing phone but this battery drain issue is extremely disappointing for $1000 plus phone. I know Apple knows about this because I have reported it to customer service who don't have any resolution except returning the phone if it still within the return window. The other solution I got was trying to exchange the phone for another new iPhone, 15 and unfortunately I would expect I would have the same problem with another device because the seems widespread. Very disappointing the way Apple is blowing this off, they know about this, whether it's hardware issue or software issue, it's their most recent addition of the iPhone, and they should act quicker than this. The battery life I'm getting worse than the iPhone 11 that this phone replaced. Disappointed with no resolution.

i've had the same experience, to be honest I've never had to fiddle with the settings as much as I have with this phone just to help an iphone barely hang on for most of the day. I find myself constantly looking at the battery percentage dropping rapidly, rather than enjoying the other features of this phone, which I like, overall except for the battery issue. I see it's a broad widespread issue.

Just wondering what support told you on call back? I am at that stage now where Apple admits there is a problem and support has escalated the issue to engineering. I have a call back scheduled at the end of the week. My iPhone 15 worked fine until 1-2 months ago - not sure what iOS version this occurred with. Currently on 17.3.1. My issue is not nearly as bad as others as I can go for almost 2 days without recharging but could go for 3 days before as my usage is very light. I charge to 100% then turn off wi-fi, cellular, bluetooth, background app refresh, location services, close all apps and shut the phone off. The following morning the phone is down 10% and continues to drain slowly without much use.

That is so weird. I have not used phone for 2 hours and battery disappear for 9 percents. All the apps were killed. Nothing lounched, 'Hi Siri' is off also.

10.00AM - 100%

12.22AM- 91%

Battery health is also 100%.

15 pro with 17.3.1 ios.

Fix this one please! I am begging!

BTW: I have been using it for 2-3 months already.

Hi there, I calculated yesterday how much battery is drained during a 45min screen recording.

The only usage was internet navigation and WhatsApp communication. (And obviously the screen recording…)

But here is the thing: Apple says the 15 Pro lasts 23h of videos.

Here are my results:

1% every 3.60min

24h*60min=1440

1440minutes

1440/3.6=400min

400/60=6.7h

This is more than 17h less announced by Apple. Note that my battery health is at “100%”.

Im super annoyed. I hope they can tell me what’s going on at the Genius Bar. I have the 45min screen recording on my phone so I hopefully won’t lose time trying to prove them how bad it is. This is outrageous. 1800€ for this iPhone. And the battery doesn’t even last 7 hours??

I have an iphone15 pro have turned off background refresh etc. When looking at my battery usage, I have noticed that the Home Screen uses the most. Perhaps the Home Screen is partially responsible for the rapid battery drain especially when the phone is not in use.

My iPhone 15pro Max (256) drains faster than my 13pro Max did and it was at 81%! I have tried turning off the “background app refresh” I set my screen so dark I can barely see it, and I turned off the “constant on display”…. No where near “all day performance”…. Apple needs to fix this or recall this phone.

I'm on my 2nd replacement iPhone 15 pro max. My original phone was purchased in Oct 2023. It died a couple of weeks ago. The message was, may not be an authentic apple battery. The replacement phone wouldn't turn on after I transferred all my data from the cloud. When I went to bed the phone was working, woke up the next morning and the phone wouldn't turn on. I now have been given another replacement. The battery on this phone drains very quickly. I can no longer use a cell phone like I've used before. This is my first experience with an Apple and I'm not impressed. I bought my phone directly from apple.com. BIG mistake. The apple support team has been great, except they were not allowed to send the phone to me overnight. I was without a phone for 7 days which is unacceptable! They did give me a gift for the trouble and it arrived pronto. The store support was the worst experience ever. I would really like my money back and go back to android. I've always used my phone instead of my desk top. That's not even possible anymore. Apple needs to fix the battery issue.

I totally agree with you, i got a brand new iPhones 15 pro max last week and it drains so fast, i used mine for about two hours and the battery went down like 10-20% if not in power saving mode which is crazy for a new phone. I have to charge my phone at least once a day and i do not even use my phone that much! It so crazy how when i got passed down iPhone 11 in 2020 would last me two whole days without charging. Apple you need to fix this ASAP this cannot be happening, keep you standards high.

Oh my gosh! I just got the 15 pro and updated everything and the battery life is awful! I thought it was just me but apparently it’s not. What’s the fix? Do I need to return it?

iPhone 15 pro battery draining in few hours. Anyone else experiencing this

Why is the battery on 15 pro max still draining after the 17.1 OS update?! It’s going down by the minute, what should I do
