Starscream122: I wander if performance is restored while the phone is plugged into AC power..

You need to stop wandering, and start wondering!  :-)

Shoes2468: I jumped on Apple support chat and got them to run a diagnostic on my wife’s iPhone 6 they reported the battery Health was good, so I ask how many cycles and they said 775 was the cycle count and battery was running at 90%. Does that sound right? I would have thought for that many cycles the battery would have depleted further than 90%

500 cycles retains 80%, thats what Apple says.

Maybe he/she meant 775 left?? Makes no sense my way or yours. 

maybe she looked after her battery well

I think it is on average that 500 cycles will take the battery down to about 80%. By that thinking, there must be phones that do over 500 cycles and are not at 80% just like there are phones that hit 80% and yet have not reached 500 cycles. If you make the % but not the cycle count then your battery is considered to have failed. If it is the other way round then lucky you I guess :)

danza: It's all kinda iffy to say "this battery will be dead after this many cycles" due to

- Differences in charging current. One theory of the 5/5s lasting longer was because they didn't get the 10/12W 'fast charging' that started with the 6. On the other hand, some people's 6/6s are not getting throttled and they just used the included 5W charger.

- Charging temp. You can kill a portable external battery fairly quickly if you leave it float charging while on top of a heater or somewhere hot eg. under direct sun light.


Still good on apple for cheap battery change or a usable phone even when the battery is almost dead.

But its not almost dead, it's potentially 80%. I always took this that the battery will just last 20% less and that will reduce over time, but it now means that at 80%, the phone CPU cannot support some apps, its 100% CPU usage, and it crashes. And given Apple's move, there must ha ve been knpowledge of this power ashortfall, or they were getting many helpdesk contacts due to crashes and they diagnosed the battery level caused the CPU to be too small. Hence, the battery is too small for the phone. When a car engine wears, its uses more fuel, it loses power, say a 2000cc now acts more like a 1600cc, but it doesnt cause the car to fail.

They're ONLY giving cheap battery change because they got caught out secretly slowing their users phones down.

We now know that Apple deliberately slowed older iPhones. However, did the same software that slowed the phones also 'speed' them up when running benchmark tests?

This article from the Guardian in October asked whether older iPhones were being slowed down (suspected at the time, but not proven as Apple had yet to confess up). The article concluded that iPhones were not slowing down based on benchmark test analysis. We now know that Apple were indeed slowing their phones, so how come this was not picked up via the benchmark tests?

Did Apple just pull the same trick as VW? ie - when a benchmark test is run, the phone's software picks up on this and speeds up to hide the secret slowing?

And in yesterday's news, Barclays says Apple's battery replacement program could hurt iPhone sales  - something which Apple must have been aware of, which makes me think their motives for the software deception may have been a little more insideous than Apple have admitted to.

I dont think people buy a new phone for the battery.

But a lot of people buy new phones when their old phones suffer from sluggish performance - esp. around the time of a new version release.

(sluggish performance aka Apple's secret software gift).

What will you do with your iPhone?
