📱 @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. 🔋⚡

Why is this not common knowledge? Is there a way to test if that’s what’s happening or something else?
It is also detailed in the Apple Support Article here:

There is no message when the background processing is complete, but if you see a lot of Battery usage showing Home & Lock Screen, that is an indicator that it is still indexing. Usually it should be done in about 3 days, give it a week to be sure. The alternative is to include the indexing/setup in the update, which would dramatically increase the update time where your device would not be usable.

Im experiencing the same issue I was about to return my iPhone.
I had iPhone 15 Plus I loved it because of its bigger screen It has 85% battery health even in this condition it was way much better than brand new iPhone 17.
what I should do now?
If you’re regretting the purchase, return the iPhone to point of purchase. But just know that when you transfer apps and data from an old iPhone to a new model, a lot of background activity will take place, possibly for a week or so. During that time you’ll notice heavy battery usage by many apps and iOS systems. This is normal and to be expected.

I am very disappointed. I have traded my iPhone 15 Pro Max in which has had a ways better battery life than the iPhone 17 Pro Max. After Apple had promised an improved battery for the new iPhone 17.
It is not just Apple that says the battery life has improved with the iPhone 17, you can find many third party sites that have actually done controlled tests that not only compared it to previous iPhones, but also from other phone manufacturers. Here are just 2 examples.
Your issue is most likely due to the apps you have installed. Some have already been identified as poor performers and you likely would not even notice an app update that introduced a battery draining bug as the only indication is a little blue dot next to the app.
For further analysis you would need to post a screenshot of the green battery graph, along with the top apps consuming the battery at Settings > Battery. It is your choice what apps you want to use and Apple lets you know which ones are responsible for draining the battery so you can make an informed decision.

If you are within the 14 days of purchase, then return it. What you are experiencing is not what has been seen by the latest 3rd party reviews. Pay particular attention to the section on battery performance in each of these reviews that were released in just the last week.
If you think there is a problem with your Software, then do a factory reset using a computer. And if you think there is a problem with the phone and it is after the 14 days for a return, then schedule an appointment for service.

Find My may be trying to find devices connected to your Apple Account. The most common reason is that Location services for Find My is set incorrectly. Follow this path,
iPhone > Settings > Privacy & Security > Location Services > Find My > While Using App > If While using app is selected, please momentarily change to Never and then back to While Using App.
The other devices on your account should be set to the same settings. Please restart your devices after changing the settings and check for 24 hours. Another possibility is one of the users on your account is constantly tracking your device or you are constantly tracking another device from your iPhone.
7-8% overnight is not huge; typically it will be 15-25%. And you should be charging overnight, every night.
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.

I have upgraded my phone with iPhone 17 pro just 2 weeks ago and now it’s battery dissipating me everyday. I used to charge my phone from 20% to 85%. From last couple of days I’ve noticed that the battery drain dramatically without doing anything. If go to sleep with 50% battery and the next day i can see only 30% left.
I don’t know what’s happening with such a premium phone like 17 pro. And what’s the solution?
Simple, do as advised by Apple for many years, charge to 100% all night every night while on wifi.
Do not go to bed without charging your phone, it will use battery checking for mail, sorting ohotis, etc etc.
Just because there is an option for charge limit you are not obliged to use it, otherwise you may as well have a battery with 85% health.

The 17 is supposed to get 12/13 hours of use time. I do not get that. I have also called & get no help. This is so wrong. I have had my new iPhone 17 for 2 months. It’s like there is no warranty from Apple. I am now angry. It’s total BS.
You will get that using the installed apps, but third party apps can certainly use more power. What did you find was using your battery when you went to Settings > Battery? Some apps have already been noted as power hungry, but it is up to the user if they want them or not.

The battery message is not normal, and you should take the iPhone to an official Apple store or Apple Authorized Service Provider.
Agreed. The keywords are "Apple" and "Authorized".

I bought the iPhone 17, upgrading from
the 14 and noticed that the battery wasn’t performing any better than my
old phone which has 76% battery health! I was also receiving a message saying the battery couldn’t be authenticated which Apple said was a firmware issue. After resetting my phone the error message did resolve but the usage did not. I decided to return the device and got a new one (from the same shop) and received the exact same battery warning. I’ve now returned both devices. I lost 20% in a 45 minute gym session only using my Spotify in the background and a workout app. Apple support suggested I turned low power mode on after charging! It’s an £800 what do
you mean!!!
Since you are just on your second day, the background processes indexing your files and updating object detection algorithms on all your photos has not even completed yet. It will take on average 3-5 days before those are completed before you are able to make any judgments on battery usage. You should expect battery drain, lag in the UI, and also the device will feel warmer than normal during this time.

Not surprising to see Instagram/WhatsApp consuming the battery. Notice that WhatsApp has continued to use your battery for more time than you actually used the app. That has been a common denominator with the Meta apps consuming the battery that were resolved when removing. Simple test after the 3-5 days is to compare your results with those apps removed.

However, you’re saying that to get the phones full battery potential you have to not have arguably 2 of the most used third party apps installed? How is that reasonable?
That is a simple test you can perform. It is the developer of the app that determines how much power they are going to consume and what background activities they are going to perform, and it is your choice to use them or not.
You would have to ask Meta why a simple photo sharing app would require so much battery power. Everyone else can do that with very little impact on the battery. Of course we know the reason and that is because in order to generate $50 billion in revenue last quarter, your data is what is being harvested and sold to advertisers. Ever wonder what they are gaining when they let you download and use their app for free?
Have you looked at the Privacy Policy page for Instagram in the App Store and the data that is collected? Apple can give you the information and even tell you the apps using your battery, everything else is up to you. Do I think that is reasonable for a photo sharing app, absolutely not, but that would be a Meta question not an Apple one? Let Meta know, even Google has called out Meta for the battery usage on Android devices.
With any new iPhone, I always calibrate the battery % by draining till switch off, charging to 100% without any phone activity, and then repeating. Before this the battery % and usage stats can be way off. Draining from 100% till switch off tests the real battery life - I find my new iPhone 17 to be on a par with reviewers findings eg 12-13 hours web browsing on wifi with medium brightness. I don’t find any excessive drain using the camera. If your battery life is significantly short of this I would get a refund or replacement.
iPhone 17 battery drains quickly with normal use
