iPhone Apple throttled my iPhone 7 by 50%

[Marshall73]

Since 11.2 Apple decided to throttle my iPhone 7 by 50%. I’m seriously pi**ed. My iPhone is only slightly over one year old. This is totally unacceptable. Anyone else experiencing this with their iPhone 7s? What can I do?

Have the battery tested then replaced.

Still quite a bit nonetheless which can certainly play into the overall health of the battery (even if the capacity part of it might not be as heavily hit).

It’s that high because iOS 11 is going to end up destroying all the batteries on older phones with crazy battery drain which Apple doesn’t want to fix because they want everyone of em to upgrade.

What are you even talking about?

It’s being said charging twice a day is a bit high. It’s not based on my experience with a 7 Plus. On iOS 10 it used to last 1 and a half days. On iOS 11 it barely lasts till 3pm. So obviously charge cycles are high.

It seems like my cpu clock speed on my X is under but with heavy load it would go up to 2.376

Would someone else confirm cpu clock frequency 2064 as a resting base?

That seems perfectly normal and makes perfect common sense how a processor should work. When idle why would you want a processor running full speed/power? You wouldn't. It doesn't. Under load when it's fully woken up sure you'll get the high frequency. It's all about the race to sleep to save power. Everyone keeps freaking out about their processor speed at any given second! It's not always going to be the same or running at the full power at all times!

Ah. My 7 Plus lasts about 1.5-2 days if I run it to zero (which I try to avoid, as it’s also bad for the battery), depending on how much music I listen to (stream + BT earphones tends to use up more juice). Been that way in iOS 10 and 11 so I’m not seeing any of this ”crazy battery drain” that’s going to cause increased battery wear.

I can’t claim that it doesn’t happen, of course; I’m a sample of one. I do believe that there are big differences in how people use their phones, however, and in network quality, that account for a lot of the variance in how often one needs to charge.

Having to charge close to twice a day sounds anomalous to me.

Maybe, but still. I prefer my phone to have a shorter battery life rather than having an insanely slow phone

The throttling has nothing to do with battery life, its to do with current. When the battery begins to degrade, it becomes incapable of supplying the same level of current as it can when its new, meaning the processor won't get enough juice to function while under load, and thus the whole system shuts down to prevent irreversible damage to the components.

Anyone who's ever overclocked their own PC will understand the concept. Unfortunately, most regular people won't have experienced this, and whilst I can understand their frustration when all they see is "my phone is slower", most aren't understanding the simple science behind it.

You can have a phone that runs slower, but still runs, or a phone that powers off every time you open a heavy app because the CPU isn't getting enough power to function. Cant have it both ways.

Not bad here

 

[Blaze4G]

Two charge cycles a day is a lot!

Not when you have the smaller iPhones that can't last a day.

Isn’t it only like $60-$80 for a new battery?

Thanks for this easy-to-understand explanation!

Having the choice to decide either path should be mine to make. Apple’s denial of throttling is in itself an issue and has led to reduced confidence in what Apple says. It has captured my company’s IT deptartment’s attention.

What do you mean about Apple's denial about of throttling? When did they do that?

Only, the OP’s phone was on iOS 10 for a full year and is on iOS 11 for perhaps three months -unless the OP was running Betas but I doubt it. So you’re not making any sense.

So a battery at 80% of its original capacity merits cpu throttling under iOS 11? Why was this unnecessary for earlier iOS versions? A battery will degrade slightly with every cycle, but for it to cause system shutdowns at 80% seems a bit wrong. I might be wrong. Might be worthwhile to visit http://batteryuniversity.com . Perhaps they have some relevant information.

As fast as ever for me

iPhone 7 Plus exactly one year old.

Run the test with all apps closed after a reboot

What do you mean about Apple's denial about of throttling? When did they do that?

Let’s call it creeping. Apple sneakily introduce performance impairing code to user devices with the assumption no one would notice.

Whatever we call it I’m going with my hunch you knew exactly what the above poster was alluding too. Denial or Non disclosure of crucial information, both, but either or’ have a ring of shady practice. Don’t you think?

 

[rukind2]

Our IT people got a run around when they went through their channels and recently the Genius Bar tech's at my local (and huge) Apple store denied it. I understand why Apple has the power management feature in the iOS, but they're facing huge criticism for not being more transparent about it.

Restarted your device and benchmark again. It made a difference for me.

 

[saudor]

so if battery current is an issue as they claim, what happens when the benchmark is run with it plugged in? Still slow?

Was this before this all came out or after? If the former, It’s possible retail employees were as in the dark as customers.

They aren’t privy to the latest info. Also possible most of engineering wasn’t aware since Apple is so compartmentalized (and secretive, that goes without say)

I believe IT started to catch wind about this through their own "secretive channels." I visited the Apple store soon after.

 

[macfacts]

It’s unfortunately 85% with 725 cycles. I’ve read that they only replace batteries for free that are 80% or below and under 500 cycles. So I guess I’m out of luck. I just can’t accept that my 1 year old phone runs slower than a new iPhone 5s :/

725 cycles in 1 year? That would mean almost everyday you drained and charged your iPhone twice. Did you do that?

 

[Jmgilliam18]

Mine is solid. But still on 10.3.3
[doublepost=1514088999][/doublepost]I don't have a mac. Just the phone. Can I run coconut battery? I'd like to see those numbers.

Thanks in advance

I find it odd that the first two posters here both posted “before” and “after” screenshots here where both the battery percentage AND the time stamp are EXCACTLY the same in before and after... yet they claim to have updated the OS between images. How is this possible?

Nevermind. I get it now. They must have screenshotted both test results at once.
