iPhone 14 Battery Draining after update

There could be several reasons why your iPhone 14 Pro Max is experiencing battery drain after updating to iOS 15.3.1. Here are some steps you can take to try and fix the issue:

1. Check Battery Usage: Go to Settings > Battery > Battery Usage to see which apps are using the most battery. If you see an app using a lot of battery, try force-closing the app or deleting it and see if it helps.
2. Turn Off Background App Refresh: Go to Settings > General > Background App Refresh and turn off the switch to prevent apps from refreshing in the background.
3. Turn Off Location Services: Go to Settings > Privacy > Location Services and turn off location services for apps that don't need it. You can also turn off the "Precise Location" setting to improve battery life.
4. Reduce Screen Brightness: Go to Settings > Display & Brightness and turn off "Auto-Brightness" and reduce the screen brightness.
5. Turn On Low Power Mode: Go to Settings > Battery and turn on "Low Power Mode" to conserve battery life.
6. Update Apps: Make sure all your apps are up-to-date, as older versions of apps can sometimes cause battery drain.
7. Reset Your iPhone: If none of the above steps work, you may need to reset your iPhone to factory settings. Before doing so, make sure to backup your data to iCloud or iTunes.

If you've tried these steps and your battery life is still poor, you may want to contact Apple support or visit an Apple Store to get further assistance.

After an iOS/iPadOS or macOS update, your device will be running some background tasks for clean-up, re-indexing of Spotlight search, among many others. I personally notice the battery takes a hit for the first few hours, sometimes a day or two. This usually won't last longer than that so you might want to check back to see.

Your Mac might send you a notification saying "Optimizing your Mac" but the same is happening on your iPhone and iPad, too, after an update.

Also—doesn't apply to you in this case but—after a major OS update (such as from iOS 15 to 16), software usually isn't well optimized, AND the user tends to play with new features and drain the battery faster.

Same problem with me

Same solutions. There are no other options.

Same problem. I noticed that Wallet has the highest battery usage by app, constantly over 71%. Strange!

My iPhone 14 pro max is drain battery after update to iOS 16.3.1

The update was performed on February 21. I have serious doubts that time will solve this issue!

This is how I solved this issue. Go to settings, General , reset iPhone, reset all settings.

Following this, my battery drain issue was solved.

I use the iPhone 14 pro max.

Yeah I can relate. I got a brand new iPhone 14 in January of 2022 and noticed battery draining and also glitching screen and shaky screen. Also my iPhone 8 I had a battery draining problem.

My iPhone 14 pro is dying so fast right now. So much for a $1k phone….

Mine is about the same, it will randomly drain in the middle of the night when on the magnetic charger (wondering if that is the issue but its random like once a week?).

Then sometimes during the day kind of after lunch it will get hot and drain while not using it or even having it on.

Since the update it uses all its power for background activities especially when no telephone reception but also Podcasts, etc. Before no problem whatsoever!

Another nuisance, my AirPods Pro do not reconnect automatically again after losing connection for a short while.

I had the same issue battery drain tried everything all usual turn off stuff. My battery was draining overnight when not in use on iPhone 14 pro max. Took it to Apple who ran a test and found camera module was failing causing drain. Phone was only months old. They put new camera/module in phone and phones as good as new. Charge at 100 overnight and when wake up still 100 percent. They said it’s a one in a thousand fault I have my doubts though. It wasn’t even showing up on battery usage. At end of day there shouldn’t be any battery drain on a phone that’s not that long on the market
