Battery Drain on iOS 26 and iOS 26.0.1.

• Have you updated to iOS 26.2?
• What is your battery health percentage?
• Low Power Mode does turn off Background App Refresh, but it is not reported to stop Background Activities of apps noted in your Battery Settings. What apps do you see using the Battery?
• How many bars are showing for your cellular connection? The less you see the more power is being used to maintain that connection whether you use Low Power Mode or not. On iPhone 12 and 13 5g remains on for streaming and downloads, where other devices turn it off.

Use Low Power Mode to save battery life on your iPhone or iPad - Apple Support

I would expect your Home & Lock Screen and Settings to be using more battery today after the update.

You still have not posted what apps are using your battery by scrolling down on your screen. Just because you aren't using an app does not mean it is not using power. The 2 you identified are the exact ones you would expect to be using your battery after an update for a short period of time.

In addition there is no word on your cell signal which is a major contributor to how much power is necessary to connect to your closest tower. The farther away it is the less bars you will have and the more power your device is going to use. The only thing that uses more power than a 1 bar signal is when it is searching for a tower.

If you post future screenshots, it is the green battery graph along with the apps consuming the battery that is the most helpful. The green graph shows rate of drop where the daily usage does nothing more than tell you what you have used. Leave it plugged in all night tonight and follow up tomorrow with your results.

Confirmed - I also disabled Find My & the battery only dropped 2% in 4hrs (yay). Previously within 4hrs it would drop below 50%.

Using third party app to see the overall CPU usage before & after it dropped from ~80% to ~10% usage.

This is on iPhone 14 Pro Max & 2 x iPhone 15 plus' - watches also see longer battery. All updated to 26.2.

So seems a MAJOR issue with core functionality of Find My.

Same here, battery drained within an 2 hrs after updates. Apple fix it. Thx

I would suggest making a new post with your device details and include the Battery Health along with the screenshot showing the green battery graph and apps shown at Settings > Battery, that are consuming the battery. The thread you posted in is now over 2 months old and specifically titled for iOS 26.0.1, which is now no longer relevant and the current version that you may be referring to is iOS 26.2, but it is unclear.

We all now that immediately after the update everyone experiences battery drain, lag, and excessive heat on your phone and also explained in the Apple Support article that has been posted here. It is a problem if that continues longer than that. If it is 2 hours after the update, you are still having files indexed in the background and you should plug your phone into power for that process to complete quicker.

<Quote> Wait another day. Mine was the same way but now It's running perfectly. I even bit the bullet and downloaded macOS 26.1 on my Mac. Everything is back to normal. Apple was right.

Also downloaded iOS 26.2 and no problems.

I don't know what followyoheart will find, but when I check, I don't see any unexpected or unknown processes running in the background. I know that one app, insight timer, now drains a lot of battery if left on overnight (it didn't used to) - I don't use it all the time. The main thing that I notice is that when I remove an app or make a system setting change, the draining seems to continue. I also noticed yesterday that my newer iPad (A16) ignored the setting request to stop charging at 80% - it just kept charging past that amount. I think there must be things that are effectively runaway processes, uncontrollable by the user, but of course I can't be certain of that.

That is normal behavior of using a Charge Limit. Occasionally it will charge to 100% in order to perform battery calibration. If you prevented it from charging to 100%, it is going to keep trying.

• Your iPad will occasionally charge to 100%—even with the limit set to 80%—to keep the battery percentage display accurate. This may happen more often if your iPad isn’t regularly able to complete a full charge.

Even if you set the 80% Charge Limit on your iPad or iPhone, it's supposed to on occasion charge past 80% to 100% to to keep the battery display accurate. That is normal and expected behavior. It's explained here --> Set a charge limit on iPad - Apple Support

And this is what it says about charging past 80%:

What to expect

• Your iPad will occasionally charge to 100%—even with the limit set to 80%—to keep the battery percentage display accurate. This may happen more often if your iPad isn’t regularly able to complete a full charge.

thank you. I see lobserghost1 has shared the same info. Once upon a time, I was a Mac support professional, in the days when apple products were easier to manage. the apple ecosystem has become cumbersome to me, but I'm not going to toss out all of my products.

You are welcome. There is no doubt adding options and features increases the complexity. In the old days you would not have the Charge Limit or Optimized Charging Settings, so the process was simple and you just plug the device in and there was nothing else to consider. When someone sees a feature on another platform, then they think it should be on the iPhone too and if Apple does not add new features then it appears the company has become stagnant.

The sheer number of Settings that can be changed on a device has increased dramatically to accommodate new features. On the other end of the spectrum, if Apple just added a feature and did not give a user any way to change it, then users complain that Apple is forcing them to do something they don't want. The liquid glass UI is a good example, where now Apple is adding additional Settings to reduce the effect for those that do not like it, and certainly increases the complexity. It's a no-win situation, you can't be stagnant while competitors are adding new features, and the features add complexity for those that don't think anything should ever change.

I’m having the same battery drain issue after the iOS 26 update. My phone was 69% about 10 minutes a, it’s down to 62% and I haven’t used the phone l…I’ve been doing everything on my android.

After typing this message it’s gone down a 1%.

And the same recommendations applies to you too. You are replying to a post about iOS 26.0.1 which should no longer be used, so create a new post with your details along with:

• Battery Health
• Device type
• Green Battery graph along with apps consuming the battery.

My phone battery drains very fast after the upgrade/doengrade. Don't care for the new features either.

Ok, if you are looking for assistance then create a new post as you have responded to an old post from October 1st about iOS 26.0.1 that is no longer relevant. The information that should be provided if you want to pursue it is:

• Battery Health
• Device type
• Green Battery graph along with apps consuming the battery.

Your point is well taken. I can report that the battery life has improved after a month of OP 26. My phone still gets very warm however.

Has anyone updated to the 26.2? And if so how has that impacted the whole battery draining and slowed processing issues?

Yes, the day it was released. I've had no issues. But then I didn't have any issues with iOS 26 or 26.1, either.
