iPhone 8, 8 Plus, and X Batteries Less Impacted by Performance Management

[MrUNIMOG]

I've had my iPhone 7 Plus for over a year now, and my Geekbench 4 score on 11.3 Beta 1 is higher than when I got it initially. Perhaps it's not being slowed yet, though I will replace the battery soon anyway.

Of course it's not being throttled (other maybe in extreme cold) if the battery is just over a year old and you've not overly abused it. Also you have a Plus model which because of it's much larger battery will be affected less and later.

If you're having your battery replaced, at least wait until the end of the year to get the most out of it.

Why aren't you charging your battery upto 100%?

It's tragic how Apple keeps up with this charade. The fact is the iPhone 6-series has a design defect that causes the phone to shutdown under peak load when using partially-degraded batteries. This is the only reason they released the throttling logic. No other iPhone model has done this before the 6-series and none has done it after. Yet Apple can't admit this, otherwise it would require a huge and expensive recall of the 6/6s rather than the bandaid of discounted battery replacements.

You don't think older iPhones with degraded batteries were affected by unexpected shutdowns? I know better.

Perhaps it occurred at a higher degradation level since CPU/GPU weren't as powerful back then (and even though less efficient, drew less peak power). But it certainly occurred. And this isn't specific to Apple phones.

So where are the Samsung graphene batteries then or can't they innovate either ? Appearing in their new S9 next week perchance ?

You're right, Android will simply shut down instead, which is what iOS is attempting to avoid.
My GF's LG G5 will simply shut off suddenly at about 16% battery left.

That's a much better user experience!

Well, no, that's just a lie I read over and over again since everyone thinks he is a battery (and audio) expert as of late

Why I know that this is a lie? I am using smartphones since the existence of smartphones and let me assure you: Yes, batteries degrade over time, but they NEVER secretly had to throttle the phone to avoid shutdowns.
Never. Ever.

I don't know how old you are and if you only have experience with iPhones, but I guess that's the case, because that's (almost) an iPhone only problem, sorry.
Everyone I know with an Iphone (including me until last year) was complaining about it.

I think apple trained its customers to think that hardware is supposed to be **** after a year I really don't get why people think that and call other people idiots, people, who SHOULD KNOW that this wasn't even the case with the iPhone a few years ago.

Ps: And YES, it also does happen to other phones occasionally, but THEN it is ALSO considered to be a faulty device. The customer knows it and the manufacturers don't lie about it, unlike apple. (This means you could return it with no questions asked, not sent away because the battery test went fine )

Faulty devices are faulty devices, no matter who build it. Please don't expect so less from current hardware. If it fails, it's a fail. Simple as that.

 

[clauzzz203]

Because it's a hardware feature of the A8. Why added it when it was needed? Well, I'm going to go out on a limb here and say because it was needed.

You're making a fool of yourself. The rule of thumb is not to say anything when one does not know what he's talking about.
Processors are able to change frequency on the fly (throttle) since 1996.

Charging up to 100% stresses the battery a lot, and will cause significantly more wear than charging up to 80-90%. Charging to 100% is the same as running the battery down to 0%. To preserve batteries in the best way, the charge should be kept as much as possible between 40-90%

Just an FYI. Read this.

If this is correct, it may not matter how low you let the charge go as long as you don't completely deplete it and phone batteries shut off before that (0% still has a charge by design) though not intentionally going lower is probably playing it safe.
The important thing I take away from this is to keep the charge voltage below 4V (below 3.92 is best but that's about 60% which isn't necessarily practical.)
So unless I need it (a higher charge), I just make a practice of keeping it between 40-60, max of 80. At least that's what I'm trying for year.
When I charge phones to 100%, I lose about 0.8% of battey health per month.

Hasn't happened on the iPhone 7/7+ (which aren't reporting throttling from iOS), which have been out as long as the 6/6+ were when they started seeing the shutdown issue.

So if performance is affected by the battery, will the user be informed?

i read some articles about keeping batteries healthy and most of them suggested this method and i went with it

We know most batteries start heading downhill after about a year or 1000 charges.

I've had my iPhone 6 for three years now and think I use it a fair amount (if you ask my partner I look at it ”all the time”) and still I have used only 631 cycles. Makes me wonder how many users that has burned 1000 charges a year. I doubt it's that many. But maybe you're not saying there's a correlation between ”a year” and ”1000 charges”?

 

[ChrisCW11]

yeah, sure, NOW. Wait a year or two, lol.

 

[TMRJIJ]

Meanwhile, Android phones don't need to use any "performance management" at all to avoid shutting down.

But by all means, Apple, tell us why this is so "needed".

I seen numerous older Android phones shutdown randomly. We didn’t need “performance management” because we were able to take the back off and replace the battery. We greatly need innovation in the Battery category now.

Teenagers, dude/ma’am. They will go through two cycles a day.

You probably never used an Android phone before, huh? Don't forget "performance/power management" differs from OS to OS.

 

[thejadedmonkey]

Believe it not some people have no idea that batteries (rechargeable) batteries wear out in time. They actually believe that after 6 months, 1 year, 2 or more, its suppose to have the same capacity. Seriously people...

I'm sure that has nothing to do with Apple claiming on their website that batteries are designed to last for 2 years before needing to be replaced, and that no care is needed for them.

 

[maverick2007]

less impacted because there is no Iphone 9 or iphone XI---- we will do it for 8/x for sure once they will iPhone 9 & XI. We know how to screw you people.

 

[tipoo]

I believe it has to do with design choice. They have to choose between small physical size, high mah rating, or longer cycle rating. Pick any two. They chose to go with a denser battery in exchange for longevity. I think all small batteries are similar to this.

The Apple Watch is decidedly smaller and has a 1000 cycle rating on their batteries page.

 

[nviz22]

I think all iPhones, running iOS 11, should have the ability to turn off throttling. There is no way for certain to know if Apple uses better batteries now than before. Can't take what they say with much certainty.

'Apple says that it will automatically re-enable performance management each time the device unexpectedly shuts down.

This feature is not a permanent toggle that you can disable once and forget about it. If you never want to be throttled, you will have to go back into the Battery Health screen and repeatedly disable it each time.'

But wait, there's more. Apple is not done screwing us, folks.

Just so I understand you correctly - you want to permanently enable a switch that will make your phone shut down at a random interval and you're mad you can't do that?

 

[udayan81]

You're turning it on wrong!

 

[clauzzz203]

Just so I understand you correctly - you want to permanently enable a switch that will make your phone shut down at a random interval and you're mad you can't do that?

Yes I do. I want to be able to do what I want and not have doubts about the performance day-to-day.

I no longer have that 6 but I really don’t like the precedent they are creating with limiting options.

They don't need hardware performance management, because by the time the battery is old, the lag is already unbearable, so people throw their phones. You rarely see Androids with over 2-3 years on the streets. You still see plenty Iphones 5 and 5s... even iphone 4's

nothing better than anecdotal evidence

I do, too.

The supposed 10.2.X fix for iPhone 6/6S/SE doesn't work on my SE. It still shuts down unexpectedly and makes it worse by slowing it down. I mean WTF!
