iPhone 6 very slow with IOS 11 update

Apple did not replace my battery, they asked me to reset my settings and wait for about 4 to 5 days to see how it goes. I reset my settings, but it’s still super slow. It’s not possible that before updating my IOS everything is great, and after that it becomes super slow and frustrating. I hate working with my iPhone and I won’t buy any Apple products.

That is great news El Paso Steve, glad to hear that worked for you, I got my wifes battery replaced and she is back up and running like new.

Also to say you started all of this!! 😁

Just kidding,

Peace,

We are done with Apple. All 4 of us are experiencing slow iPhones so don't tell me it's the phone. We are moving to another brand next week. Anything has to be better than touching an app and waiting for the phone to respond. Ridiculous.

I'm sure that whatever you get will be perfect. You will never have any complaints or problems. You should always get the product that best meets your needs.

BTW, None of the other users in this user-only forum cares what you do.

Just checking in a few weeks after my wife's iPhone got a new battery, it has still been working like new, only costs $30 bucks, and a 1 1/2 wait at an Apple Store. She has an iPhone 6, her old battery had many cycles on it, and after the battery was replaced, no troubles, all apps work very fast,

It seems that the 11.3 , although in beta the battery part, gives again soles to the mobile!!

I do not trust in the explanations they give (the peaks of cpu usage, etc...) but it is going quick again.

To much time in repair this, but seems to be going better.

Still you can not manually select the mode, but well

I had the same experience. It's like night and day. I have my great old fast iPhone back. It just goes to show how much Apple messed up the operating system update.

I highly recommend anyone with performance problems upgrade to iOS 11.3 to get this fix.

We did well to push Apple....

I stooped my new devices purchasing, even the battery replacement, until I saw a real movement from apple to solve the big mess they initiated with the 11 version.

I Betina to trust again... this is an upgrade, the previous versions were a downgrade!!!

If your iPhone 6 battery is bad or not performing at a certain threshold of acceptable performance, this iOS 11.3 update does NOTHING to change the condition of your iPhone battery!

If you turn off the CPU throttling and your iPhone 6/6S/6S Plus starts having random shutdowns due to CPU and battery overload, you will STILL need to have your iPhone battery replaced!

Replacing the battery is the only way for your phone to regain full performance - and that at all battery load levels.

I just had this done this morning. Now my phone runs at the nominal CPU frequency (1400MhZ) just like when it was new.

There is no "big mess" to solve. All Apple did was to gradually reduce CPU speed as the battery degraded to protect it and extend its life (and prevent sudden phone shutdowns).

Sorry, but that is not true.

Now without changing any battery, the iPhone now goes well for me, and for other users...

It was really a bad action by apple the IOS11, now they have repaired it with the 11.3; yes it was a mess, really a mess. Do not asume it is not say the truth.

Now if you want more duration for your iPhone, change the battery.

The story of the peaks of use... it an story for children.....

Yes, it's absolutely true. iOS 11 used dynamic throttling on older batteries. iOS 11.3 allows you to turn it off. That's all. If it's turned off, you won't see the performance hit but your battery may drain rapidly or shut off unexpectedly. The only way to resolve that is with a new battery.

If you think your phone got faster with iOS 11.3 and you haven't disabled the throttling, then, the difference is not in the phone or it's behavior but in your perception.

no, and no... my perception? seconds (2 to 5) to appear the keyboards when chatting, or the characters after begin to type? seconds for seeing a call after hearing the ringing? seconds to initiate the camera? 10 seconds waiting to appear the contacts when begin to write an email, ...

Really I do not understand the objective to discuss against the facts, but you are free...

Ah! the battery has similar duration, and no unexpected crash until the moment.

Do not count stories for children ... it was a botched, and now they have solved, Thanks to apple for the moths of delay in doing it, a lot of trust lost, but I want to recover it.

If you think your phone got faster with iOS 11.3 and you haven't disabled the throttling, then, the difference is not in the phone or it's behavior but in your perception.

When you install iOS 11.3 throttling is disabled automatically. You don't have to take any action to turn it off. Throttling will only be turned back on if your phone has an unexpected shutdown.

So, this is not perception or imagination. iPhones with old batteries that were being throttled under previous versions of iOS 11 get an immediate performance improvement when iOS 11.3 is installed, even without a battery replacement. Of course, if you experience unexpected shutdowns or other battery problems, throttling will be turned on. At that point you can live with it, you can turn it off and take your chances with shutdowns, or you can replace the battery.
