Apple Studying Issue With iPhone 6s & 6s Plus Not Updating Battery Percentage

furi0usbee said:
i wonder if Apple is playing with the percentage like they did with the signal bars...

EDIT: I still have the iPhone 5. And I literally can be on 1% for 45 minutes, or be on 39% and then restart the phone only to find out I'm at 8%.

I know someone with the same exact problem. And opening certain apps will cause the battery percentage to drop 10% at a time.

She's on her third iPhone 5, and all of them have had the same problem...

I have this issue but i have not changed the time at all i did a restore same issue i'm taking it to apple for replacement

What good would it do to take it back to the store for replacement when they haven't solved the issue yet? You'll just end up with a new one that does the same thing.

My understanding was that '100%' was not necessarily just 1% worth of battery on top of another 99, but rather about 3-5% worth of battery that is drained and recharged when someone leaves the phone on charge at 100%.

99% + 5% = 100% ? lol I love how Apple plays these psychological games with people.

I´ve got the same problem, but I've never changed the automatic time and I´m on an iPhone 5. I hope they fix it soon.

My iPhone 5 was pretty bad for awhile, would randomly hold or drop percentages and sometimes would die at 20-30% but you could do a hard reset and it would come back on, then I went ahead and put a new battery in it and it is much better. Strangely my phone wasn't eligible for the battery replacement program either. But anyway, a new battery may help you.

Maybe it's a combination of time settings and specific batches of phones.


Yes they do and afaik they admit to it.
What you described however seems to be a battery calibration issue. At least the latter example.
The former is by design.
Ever noticed you see 100% a whole lot longer than 98% for example?
Psychological reasons. You don't want the customer to see the drain right after unplugging the device.
Apple's not the only one to do that.

And as for 1%, that's not actually 1% either, the battery is always left with a remaining charge of 2-5% iirc in most cases, because actually emptying the battery can harm it. Running below 20% and above 80% wears out a battery too, but it's really a complete discharge (not what the phone force shut downs you at, but say leaving the phone uncharged after that for a prolonged time) that can ruin the battery.

Actually the reason that it stays on 100% for longer sometimes is because Apple actually charges the battery to 105%ish so that it can then start to discharge the battery while still have 100% left. This is because it's bad to keep charging the battery if it's full. So when the battery is at 100% and plugged in its actually cycling and you could unplug it with more then 100%. So it'll seem like you have extra time on 100%

Which will still do way better then human error. My autonomous car will at least always be watching the road, and not looking down the read a text

The phone went to 20% and then turned off. Plugged it in, back to 19%. Weird Apple battery issues.

I had something like this last week. I was planning to buy a car and left home with iPhone fully charged, but when i reached the dealer i checked my phone and it was 33%. Strange, ok, so i found a cable and connected it. Battery level jumped to 97% in few seconds.
 
I think they count time to measure battery percentage. Back in 2011 they said that no accurate method to measure battery charge percentage.
Sometimes my 5s does this indicator issue but in a versa way, the last time it happened it was on charger and the indicator was showing 98% for a long time and when I unpluged it the indicator turned 100%.

Maybe updating battery status too often would use too much energy and drain the battery. Yay for thinner iPhones!

Surely iPhones have gotten thinner but the battery life have also improved and the last 2 models 6/6s (+) have got the best battery life of all iPhones. Yet people keep putting the blame on phones getting thinner because somehow they seem to think that the solution would be to have a brick battery on it and not working to make the device less power hungry. Besides, it doesn't really matter if battery life is a day or 2. People would still then want it a week or a month. Because you know, plunging a device on charge before going to bed is just too much inconvenient for the 21st century people!

"I have a different model, and have the same problem."

No, you most likely do not. You're doing what every layman does when they hear about a disease. They assume that because they have one or two symptoms in common with another person, they have the same illness. Lots of illnesses have symptoms in common.

iPhone 6 upgraded to iOS 9 has better battery life than 6s. This is not the improvement I would expect from Apple.

Guess what, doing it every second day is less inconvenient!

That proves my point exactly. Battery life improvements can be made through software efficiency and not just by slapping a big ass battery on it.
 
Seems my 5S isn't due for a replacement then. I've had a similar issue, where it hits 30% and then decides there's no battery left and switches off. Won't switch on unless I plug it in...this might be the cause for it...will wait for a fix (or the 7 plus, whichever comes first)
