iPhone 17 battery drains quickly with normal use

I’ve got an iPhone 17Pro, a present from my husband. My last phone was an iPhone 12 Pro and the only issue was the battery draining too fast, due to its age.

Now it seems to me that the brand new iPhone has the same problem. Charged all night and the battery lasts around 7 hours!

You should be getting more than 7 hours of battery life. Post a screenshot of Settings > Battery that shows your green battery graph with the last 24 hour option including the top 5 apps consuming your battery.

I would assume you are not using a 80% charge limit as that would start your day with the battery already depleted by 20%. If your top app consumers are Social Media, try removing and compare the difference.

My brand new iPhone 17 does not hold a normal charge. Why is that very disappointed and I want to turn it in

You have 14 days to return the phone for a full refund.

Hi! I just wanted to confirm that I’m experiencing exactly the same issue on my iPhone 17 Pro Max (iOS 26.0.1).

My phone is brand new, 100 % battery health, recently returned from Apple Service (no hardware issues found).

Despite a clean setup and no background apps, I’m losing around 50–55 % in about 12 hours of light use (mostly Messenger, web browsing and short calls). Overnight it also drops several percent while idle.

You should be charging your phone all night every night and I recommend using the Optimized Charge setting. If you are using a charge limit, you are already starting each day with a partially depleted battery. Your phone under any iOS version is going to drop several percent overnight while idle. What you described is having all day battery life. Don't get caught up comparing Screen on/off time as you can see adding the 2 together never equals 24 hours which are the only 2 states other than when your device is powered off.

Overnight I lose 8% in mine 17 pm, Airplane mode off, no running, Power safe mode on,

Who experience like me?🥹

Just about everyone with an iPhone (or an Android), except most people who don’t charge overnight can see up to a 25% drop depending on their settings.

Any cell phone uses energy continuously, as long as it isn’t powered off. This means that if it is not connected to power for 8 hours the battery level will be lower at the end of that time. How much lower depends on what apps you have, how many notifications you have enabled (which will be delivered and processed by apps even if you force close apps-they will relaunch when a notification arrives), and, probably most important, how strong your cellular signal from the network is; your phone maintains a "conversation" with the network so your phone can be found when a call or text arrives, and low signal strength requires much more energy to do this update to the network. Thus, you should be charging your phone overnight so this nighttime usage is powered by the external source rather than the battery.

You are only using 60% of your phone battery, so obviously you are limiting the amount of use time. My recommendation is to use Optimized Charging and charge your phone all night, every night. It will learn your charging habits and only charge to 80% until just before you normally take it off the charger where you will then have a 100% charge. Quit using a Charge Limit and quit trying to manually manage when and how long to charge your phone. Your phone is meant to be enjoyed, not managed.

In any case, if you are not happy you should return the phone and make sure you do not exceed the 14 days.

I just purchased the iPhone 17 & it’s the battery life is the first thing I noticed. I am very disappointed with this phone & the battery life. I must charge it every night & Find My iPhone is the number one battery drain each morning. I have decided to just turn it off. I have researched this & tried everything, but nothing works. I am beyond frustrated. The phone is not cheap & I certainly expect better from Apple.

You should be charging it all night, every night and use the Optimized Charging option. It is that regular charging pattern where you will see your phone learn to charge your battery to 100% just before you take it off the charger. That is also going to reduce your Charge Cycles since the normal maintenance routines performed overnight will be using line power instead of battery power. You will be starting each day with a 100% charge and can concentrate on using your phone like it was intended.

The insane battery drain is happening not just on my old iPhone 17 but ALSO ON THE REPLACED UNIT FROM APPLE, I DON’T KNOW WHAT HAPPENED!

SHOULD I RETURN IT?

The chances of two new phones issued to you being faulty is so tiny that the common factor is most likely your app fortfolio.

📱 @Apple I recently upgraded to the #iPhone17 and the battery drain issue is really disappointing. Even with normal use, the phone loses charge way too fast. For such a premium device, this shouldn’t be happening.

Please address this with a fix/update soon. 🔋⚡

We’re just users like you. And some of us have been using iOS 26 with no problems at all. What I’m getting at is this is a problem with YOUR iPhone, not something that Apple can fix by waving a magic wand.

From→About Apple software updates - Apple Support:

Immediately after completing an update, particularly a major release, you might notice a temporary impact on battery life and thermal performance. This is normal, as your device needs time to complete the setup process in the background, including indexing data and files for search, downloading new assets, and updating apps.

“My battery drains without using.

When I kept 40 before sleep and in morning it will in 20 percent. I’m very disappointed “

Relatively normal. Charge it while you sleep, all night, every night. As recommended by Apple and everyone here.

Now if it lost 20% while powered off that’s a different problem - self draining battery.

I'm unhappy with my purchase and within 14 days and Apple support and ATT are not assisting with getting rid of this dog of a phone. Iphone 17 pro with no battery life. I feel bamboozled. I don't want this phone now.

Assuming you bought it at AT&T, remind them of their return policy as seen here:

• If you bought your wireless device at att.com, over the phone with AT&T, or at an AT&T branded store, you have 14 days to start your return or exchange.

20% in 8 hours is pretty good, your phone is never idle. If it is out of your reach for the shift then turn on low power mode while in the car.

Same issue here. New iPhone 17 with all default settings. I’m only using 3 hours of WhatsApp and 1 hour of YouTube and I’m already at 20% battery left. So no camera, no gaming, nothing special. Brightness only 33%.

It’s very disappointing with a new phone.

I come from a 12 pro with 5 year old battery at 75% that performs even better.

I use the 17 and honestly, I am very disappointed with the battery life. I can hardly get five hours of screen on time before I need to charge. I also noticed standby battery draining, It’s not the best especially having used the 13 and 15 base models . I think it’s an issue with all versions, probably an update might just fix it .

Also, I have been using the phone since its launch date so this isn’t about me just transferring from an old device. It’s been almost 3 weeks and there’s been no sign of improvement.

Me too, very weird. My iPhone 17 Pro Max was manufactured on August 2025. Im starting to think its a hardware issue that the first patches of iphone set deal with.. We need a replacement for this trouble. Also, just by using Safari, my iphone becomes very warm.
