iOS 11.2.1 IPhone 7 Slow & Lag

Most of the stuff in my very short list of tips (I have a much longer one available) are ALL battery hogging and performance improvement stuff you should be doing, anyway, to make your iPhone even faster and to make the battery last longer.

The iPhone 6 CPU/battery slowdown code Apple interjected into iOS 11, unfortunately, seems to have affected some iPhone 7 users, also.

If your iPhone 7 and it's battery is well over a year old now, Apple opened up its reduced price battery replacement program to ALL iPhone 7 users, as well.

The iOS 11 CPU/battery performance slowdown code was, specifically, targeted at ALL iPhone 6/6S/6S Plus models, but appears some iPhone 7 models may have been affected, as well.

Take your iPhone 7 models into your “local” Apple store and have them check the health of your iPhone 7 battery.

The replacement battery is only $29 U.S.D., now and for the rest of 2018!

Good Luck to You!

Contact Apple for a battery replacement.

See my comments above.

Perform all of my performance/battery improving tips above in my earlier posting.

Another NEW battery/performance improving tip is to go into the Settings App under Notifications and only select apps you need Notifications from and edit the methods for which you receive these Notifications.

You do not need notifications for every single app on your iPhone/iPad AND you do not have to get Notifications using ALL three notification methods!

Again, Good Luck to You!

Hi,

Using 6s with ios 11.2.1. Battery drain. Once 30 percent is reached after using for a while i can see the countdown to 5 percent withing less than 10 mins. The other issue is lag. I never expected this. Is there anyone else whose home screen while switching lags? Same in other apps too. Safari crashes sometimes.

Are you guys sirious? We buy te gratest, fastest, smartest iphone 7 with all the futures designed by apple, to turn off all that futures? APPLE seems to go down and make us buy expensive devices that last only 5 months and then, take the device to trash? I am verry dissapointed by apple.....

I have the same issues, I won't buye a new Iphone. If Apple can not solve this problem, i will buy a new Phone but not Iphone again. That's why i won't hold any stocks of Apple.

You're NOT addressing Apple or any responsible, cognizant Apple teams or employees here.

These are user to user product technical support community forums.

Aside from Apple Support Community specialists and staffers moderating these forums, and the occasional Apple technical support specialists, who help us all out here, from time to time, we are all users, like you, who volunteer our time and extensive Apple product technical knowledge to help out our fellow users with Apple product technical issues and solutions.

Try any of this advice, first.

Have any of you tried a hard reset of your iPhone 7 by holding down both the Home and sleep/wake buttons until your iPhone goes to black and restarts with Apple logo, then release the buttons

In Settings app, General settings panel, turn OFF Background App Refresh.

In Settings app, under General settings, Reset panel, at the right bottom of the list, Reset All Settings.

In Settings app (NOT from the iOS Control Panel) turn OFF Bluetooth when not using any Bluetooth devices.

Also, in general, if you want a faster IDevice, on all of my iDevices, I turn off most of the iOS motion graphics eye candy, by simply turning ON Reduce Motion in Settings app, General, Accessibilty settings.

Make sure you aren't running scads and scads of background apps in the iOS 11 Control Panel/App Switcher.

Also, make sure you don’t have scads and scads of active website tabs running in the web browser.

What about doing a complete backup to iCloud or iTunes on a computer, then do a complete erase and reset as new in the Settings app under General, Reset then restore your backup from iCloud or iTunes?

If still no joy after the erase and restore, hammer Apple with constant feedback about the iPhone 7 issues here.

iPhone Feedback

http://www.apple.com/feedback/iphone.html

This is THE ONLY avenue to get Apple’s DIRECT attention to any and all iPhone 6 issues!

IF no one continues to post regular feedback about iPhone 6/6S issues, Apple will NEVER know there is an issue and will never correct it!

Cognizant Apple employees read ALL feedback generated from all of the various feedback pages and transfers the data to the appropriate Apple personnel , but NO Apple employees will ever respond with any type of direct, individual replies from the feedback you post.

Also, it maybe possible that your iPhone 7 battery may an issue with degrading capacity and charging performance.

If you can, bring your iPhone 7 into your “local” Apple store for a free a complete diagnosis and costs for possible repair/replacement or battery replacement.

If you can wait, sometime this January 2018, Apple is dropping its replacement battery pricing from $79 U.S.D. to $29 U.S.D. AND this reduced battery replacement pricing will stay in effect until December 2018. Nearly the entire 2018 year.
