Iphone 17 pro max battery drain

Well, Contacts is suspiciously high. Do you sync contacts to iCloud, or some other email provider?

You also have Facebook and Messenger. Meta products are notorious for inefficient energy use, and for “parasitic” use through heavy use of other apps, primarily Contacts.

You have a 3 bars cellular connection, which is pretty good (lower cellular signal strength significantly increases energy drain, and doesn’t appear in the usage graph).

Have you updated to 26.6.1 or 26.6.2? That would be a first step.

Have you tried restarting the iPhone?

Do you have VPN installed? That can be a real energy drain that does not show up in the report either. If you do delete the VPN profile in Settings/General/VPN & Device Management/VPN, then restart your device. Don't just turn it off; delete the profile. 

Bottom line is nothing stands out as a heavy energy user. You understand that it is apps, the screen and your cellular network connection that are the primary users of energy.

Hi! I can see from your screenshots that YouTube and Safari are using a significant portion of your battery. Here are some tips that might help improve your battery life:

1. Reduce screen brightness or enable Auto-Brightness. The display is one of the biggest battery consumers.

2. Check Background App Refresh. Go to Settings > General > Background App Refresh and disable it for apps you don't need updating in the background.

3. Turn off or limit location services. Go to Settings > Privacy & Security > Location Services and set apps to "While Using" instead of "Always" where possible.

4. Disable Always-On Display if you have it enabled. Go to Settings > Display & Brightness > Always On.

5. Turn on Low Power Mode when your battery is running low. It limits background activity and can significantly extend battery life.

6. Update to the latest iOS version, as Apple frequently releases battery optimizations.

7. If you're on 5G constantly, try switching to LTE for everyday use. Go to Settings > Cellular > Cellular Data Options > Voice & Data and select LTE.

8. Check Battery Health in Settings > Battery > Battery Health. If your maximum capacity is below 80%, a battery replacement might be needed.

Since your iPhone 17 Pro Max is new, the battery should be performing well. If the drain continues after trying these steps, I'd recommend visiting an Apple Store for a diagnostic check.

Hope this helps!

What model iPhone? How old is it? What is its battery condition shown in Settings/Battery/Battery Health, and what is the maximum capacity?

If you charge overnight, every night (a best practice) does the battery need to be recharged before the next night? If it doesn’t the phone is working as designed.

Yes, it is a software issue, but not with the release. If it was, with several hundred million users of iOS 26.6 there would be tens of thousands of posts about it and news on every tech website and Forbes, and it might even make the New York Times.

The release may have triggered a problem with other apps, but the release itself is not the problem.

BTW, how long ago did you update? After an update iOS rebuilds its databases, which uses energy for the first few days. And 26.6 included a major restructuring of internal data structures in preparation for iOS 27.

Here is Apple’s guidance:If the battery in your iPhone drains too quickly - Apple Support

17 pro Max, pretty much 1 years and cupola months. Have to recharge by 19h00. Or less. At beginning of the phone I could use pretty much 1 day and half before charging

and I am not using a lot the phone ..

Battery is 99 % Healt

itd really really worse since the last update

hi,

its a software issue. I know FB and messenger can really drain the battery but with the % we see, there is certainly something wrong with the new IOS update and optimization.

And it’s not the first time I am seeing that’s on apple device. I am using apple device for last decade or so :)

OK. Someone else recently recommended someone update to iOS 26.6.1 on their iPhone and I was thinking I must be missing something.

Thanks.

26.6.1? Are you referring to a beta release? I haven't been offered 26.6.1 or 26.6.2.

Sorry, no, I was thinking of MacOS, which is up to 26.6.1. And the others are <redacted>
