Many of my friends with iPhone 6 and 6S had the same problem.
They were calling me asking if I could replace their battery but I didnt want to risk opening it and buying 3rd party batteries to replace.
And Apple would not replace the battery for free.
They wanted to charge them $80 and were telling them mind as well upgrade to the newest iPhone instead of spending money on fixing the old one that is slow and outdated.
Totally shady since they knew their batteries were crap and instead of replacing all of them for free they were slowing down peoples devices on purpose to get them to buy a new iPhone or pay $80 out of pocket to replace their defective batteries.

Yep we had to pay $80 for a new battery. In so doing they destroyed my wife’s iPhone. Never got that $80 back but did get a new iPhone for free. :/. Very shady on Apples part. Not something you do when you want to keep customers.
 
I just sold my ip6. It was doing random shut offs at 30-40% and was slow as heck. I just figured iOS 11 was to blame. Huh. Damn you Apple. Cost me $1,500.00 bucks.
 

I’m curious, in the article above it states the following:
As for why the iPhone 7 and newer aren’t affected by this issue, Apple’s A10 and A11 chips include an additional fifth core that runs at a lower clock speed. This core is used in conjunction with the full-power cores to help offset performance and battery life concerns.

Any idea how they are stating the above so factually that the iPhone 7 and above won’t be affected in the future by this deliberate Apple slowdown of iOS devices?
 

I wonder if always running it in low battery mode has helped to keep it healthy. It seems to be doing very well for a year old device.

What do you think?

Where are you getting that screen? I've had Battery Life for years and lost that data with either the iOS 11 or iOS 10 upgrade, I forget which. I just poked around and can't find anywhere with that info. What version of iOS are you running?
I'm running iOS 9.0.2.

At the initial screen to the top left are three horizontal bars. Press on that.

He’s running iOS 9 :) I believe he is jail broken too.
Yes, and yes.

But the app itself is in the App store so it's not giving any data via my jailbreak.

Probably an iOS 11 thing if it's not showing…as you indicated earlier.

Probably better to use Coconut Battery for the Mac. I understand not everyone has a Mac but I would think for those that do it is the most accurate for mAh reading.
This is what I am getting from DataMonitor which IS a jailbreak app.

How did Apple destroy the phone. Makes me worried if I take it to Apple. Who actually does the battery replacement? A genius who specializes in replacements or the average Apple employee?

My ip6 is getting a new battery right now. Ill post the results over the next few days. Battery was at 82%, 482 cycles or something like that, so it was close.

My phone has been painful for several months. I dont remember when i upgrade to 10.2.1.

If i can get another 1 year or more for $80 I'll be ok, but this could hurt Apple big time. They better have a good response
 
Are you kidding? Id love if they toasted my phone during repair. Then Id get a new one, lol
Last year I dropped my phone and cracked the screen so badly that the phone was bent and the Apple Store staff couldn't mount the new screen on it and offered a replacement device for the price of a screen repair. Great savings.
 
so bad battery, leave device plugged in, do benchmarks still show subpar performance? with device connected to ac source, health of battery really shouldn't matter.

We went to Apple Store in the Northridge Mall - showed them my wife's iPhone 6s+ and how it restarted randomly under 60% - they ran tests, 3 times, all failed -- but the rep refused to replace the battery saying there was nothing wrong with the phone. So I said I'd just pay $80 for a new battery. Took them 2 hours to do it - right before closing they handed it back to us. Half the backlight wasn't lighting up. So we said why is this not normal? They took it back and within 5 minutes came out with the phone "fixed" saying they forgot to re-attach a cable. On the way to the car the phone rebooted 6+ times. We were treated badly by this store so we said f-it... we'll just go to the store we normally go to by our house - walked out with a free 6s+ replacement and an apology - but they couldn't refund the $80. The Apple Store rep closer to our house was really nice, professional, and great.

Exactly. Though, in my case, I lost $80. lol. But oh well.

My experience has been that Apple replacements are better than others, even what I'd call name-brand replacements like iFixit.

My experience as well. I'd rather have an Apple refurbished unit than unboxed new.

My battery is replaced, and GB is reporting improved performance. Here's 3 GB4 runs before and one after replacement. We'll see how it lasts over the next week or so.

edit -- and just to be clear, the highest rating at 1500+ was on the new battery at only 29% charged.

What’s the consensus on Apple batteries. Are they junk?

On average, Apple batteries are FAR better than the competition. Just the 6s/6s+ batch had issues I think - and of that, only a small percentage. And instead of just replace all the millions of 6s/6s+ phones they tried to minimize the problem with the downclocking. (My guess). Out of the millions of 6s+/6s owners, maybe only 30-55k had problems and of that, only a few thousand knew about it. (again, this is a huge assumption on my part).

But in my experience, Apple Batteries are exemplary. My 6+ had ~240 cycles after almost 2 years, 97% life left. My 6s+ had 220? cycles after 1.7 years and 95% life left. My Samsung Note 3 after 150 cycles had less than 60% life left (yeah probably a bad battery) - but my coworkers Note 3, same thing, and my coworkers Note 4 phones - same thing. The only good thing about Samsung, the replacement battery cost $10 on Amazon and with a removable back it was easy to replace.

I'm a HUGE battery OCD nut - and Apple's batteries are amazing imo - the hardware and battery are big reasons why I own an Apple.

Wow look at that. Hard to argue with those results. That's proof in my book - quite a few others just like you.
