Why is my iPhone 15 Pro battery draining so quickly?

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.

Hello, please I would like to know, I also got a 13 pro max and lasts me all day, I have 7hr daily average, will the 15 pro last enough? Or I should get the pro max? I really wanna upgrade but I see the max series a little to be big and uncomfortable in my small hands? What should I do?

As no one here knows exactly what apps you use on your phone, what your cellular signal is like, and what your settings are, that's a hard question to answer. It's also a different phone with a different chip than the one you have now.

I have found the battery life on my iPhone 15 Pro to be great. If you buy the phone from Apple, you have 14 days to try it out.

I’ve had mine for about a week. I parked my vehicle with the phone at %80, walked five mins to the job site… battery was %72. Now 1.5hr later the battery is %65.

not running many apps in background, always-on display is deactivated.

Me too! Actually I bought a new IP 15 pro a week ago and the battery is reaching 40% after only 4 hrs of noncontinuous use!! And I’m super confused and I don't know if this is normal for iPhone 15 pro!!

Hello!

I'd like to know if you've had it serviced? 

You summed up my whole situation. I bought the IPhone 15 PRO in October/23 and my battery drains 20% in 10 minutes in the morning without accessing social networks. If I turn on the Bluetooth, my battery runs out by lunchtime. I don't have the freedom to listen to music or go online if I have to be away from home all day. Disappointment. I exchanged my iPhone 11 because I thought the old one discharged quickly. Utter garbage! This battery has failed. 

Thanks!

I just got my 15 pro last week. I upgraded from a 12 and the battery is horrible! My 12 will last at least a whole day. I watch YouTube and Netflix all day at work and the battery would still last. This 15 is a headache! I'm so disappointed in this battery. It's supposed to last up to 23 hours but that a lie! My phone was on the charger all night. I came in at 6am, it's 1230 and my battery is at 47%. I'm in training so I barely touched my phone. Not ok! I'm so mad I went through so much to get this phone.

I’ve had my iPhone 15 Pro for Atleast 8 months, 9 months give or take. And it took 14 continuous hours to drain 50%, just try charging it and letting it run dead.

Completely draining a lithium-ion battery is something you want to AVOID. It can permanently damage them.

I bought my Iphone 8-month-old and now , iPhone battery life is at just 90% life. When I called Apple customer service to replace my battery, which is still under warranty, they asked me to wait until the battery life drops to 80%. wonder was he joking?

cause by then, the warranty will expire.. what is the sense of a warranty? I need clarification on why the battery is at 90% after just 8 months and request a replacement immidiately. I am not gonna spend money over faulty Iphone sold to me.

No, they weren't joking. Apple considers the battery fit for use until it drops below 80%.

The purpose of the warranty is top cover things that fail earlier than they are predicted to. If your battery is above 80% a the end of a year, then it has not failed.

iPhone batteries, on average, lose about 1% capacity a month. However, that decline isn't linear. Capacity declines more quickly early in the life of the phone and then generally slows. You may find that your phone stays at 90% for months. Based on the information you've given, there is nothing to indicate that your phone is "faulty".

I also regret upgrading to the iPhone 15 pro. I sadly shattered my 14 pro which is the only reason I got this new phone but it has turned out to be a huge waste of money. Battery life is atrocious and unacceptable for the cost of this phone. Honestly think my next phone will be an android. I’m tired of the apple issues.

Apple iphone 15 battery life is very poor and mine struggles to last a day when I’m out, without a recharge!

I’m not a heavy user and I’ve methodically gone through all the energy saving hacks.

I’m committed to Apple products but I remain wary of iPhone 16 in case it has the same issue.

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

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

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