For build 14E5230e I reported feedback that my phone (6s) was getting warm and had approximately 50% life. Don't remember which beta rev this was.

Apple responded today 3/21/17:

There are changes in build 14E5277a that may have resolved this issue. Is this issue fixed for you in this build? If you are still seeing this issue, please provide any reproduction steps so we may investigate further.

My phone certainly seems better and improved at least so far as I can tell.

I meant- when the battery power level is at 40%, when you observe the rate of power consumption and decrease in battery level, it is very fast as compared to the rate of power consumption and decrease in battery level when the battery level is at 70-80%.

That is like my car's gas gauge. I get 200+ miles on the first half tank (by the gauge) and maybe another 100 miles on the 2nd half.

Our iphone battery should nit behave like this.
[doublepost=1490150256][/doublepost]I got replies from apple saying the rapid battery drain issue should have been resolved by beta 7. As requested I submitted a new feedback indicating it had not been fixed, at least in my case.

Kind of true. The percent is an estimate, but it is still linear in comparison to the remaining mAh of the battery. Thats the key point that everyone should remember, its an estimate based off of the remaining mAh.
I am meaning that is doesn't change at a smooth consistent rate. Obviously a phone that has been used for 30 minutes cant be at 100%. The percentage doesn't change in equal increments from 100-1 as its being used. Example maybe 1st 2 hours use reports 80% remaining but the next 2 hrs may be down to 20%.

Yes, thats because iOS meter doesn't start moving until the battery is at 95%. But all Apple products are like that. Even Macs. But its still a linear drop. I gave the numbers above on how it drops.

Do you have proof that the battery meter doesn't start moving until the battery is at 95%? Because I don't believe that for a second.

Seriously? Its been known for years and years now. When CoconutBattery was an iOS app it was easily verifiable. But anyone with a Mac can verify it with Coconut battery.

Its easily verifiable doing the opposite. When charging the iPhone, the iPhone hits 100% just as the battery hits 96% charging. Apple does this intentionally. iPods, iPads, Macs, iPhones.

I guess I should elaborate why its intentional. iOS devices start to discharge once the battery reaches 100%. The battery discharges until 95% and then begins to recharge. Apple doesn't show this 5% battery difference because technically the battery was fully charged and is in the process of either recharging or discharging. If the battery meter was always 100% spot on, you would constantly be seeing your battery meter go from (even when the device is plugged in and that would confuse people):

100 -> 99 -> 98 -> 97 -> 96 -> 95 -> 96 -> 97 -> 98 -> 99 ->100 -> 99

So Apple decided to just make the battery linear form 95%.

100% = 100% -> 95% actual
50% = 47.5% actual
10% = 9.5% actual
5% = 4.75% actual
1% = .95% or 1% actual

These numbers are 100% verifiable and I am not the only one to pass this information along.

Here is a perfect example of my MBA:

Screen Shot 2017-03-22 at 9.40.12 AM.png

My MBA is reporting 90% but if you calculate out the mAh directly, its 85.7%.

If I am at my computer as it hits 100%, I will post another screenshot.

Screen Shot 2017-03-22 at 9.59.41 AM.png

Here we go. 100% macOS reporting = 95.3% actual battery.

Here is iOS proof.

Sorry for the horrible photo, used my iPad instead of screenshots to prove it side by side.

All Apple devices show a 100% readout as the battery itself is really only 95%. In this case, 94.8% = 100%.

Not exactly correct. I do see 99%, 98% and so on quite often. So if I understand what you are saying, I would see 100% then the next increment would be 95%? Nope not the way the battery meter works. I have no idea about your 3rd party utility and what it may or may not show but I am referring to the Apple percentage meter that's built in. It does move but not in a uniform increment and it does start before 95%. That's all I am saying.

No, you're not understanding. The iOS battery meter remains at 100% until the actually battery is 95%. Then it drops linear. 99% reported = 94.05%, 98% = 93.1% and so on. Just as I posted the numbers above. Its not until 1% that both the actual battery and iOS are in sync again. That is why Apple recommends draining the battery all the way down to re-calibrate the percent meter in iOS.

No where am I saying that iOS meter skips over 95-99%. I am talking about the battery itself based on mAh calculations. I provided 3 screenshots above to prove what I am saying.


Edit:
The biggest thing to remember is that Apple has always claimed the % meter is only an estimate. The only true way to calculate remaining battery life is to track the mAh.

OK got you. Essentially we are saying the same thing. Apple battery meter is an estimate at best and not 100% accurate :)

Yep! That exactly correct. All the complicated stuff occurs in the background and Apple does not share that with us. :)

I unplugged from charger about 8:30 AM 100%.....now at 2:00 pm, with modest use some standby....35%

What are the usage and standby (although that one is essentially known) times? What's listed as one of the main things that has been using the battery? How has the cellular coverage been throughout the day?

beta 7 is horrible beta 5 and 6 was butter smooth and animations was super fast now with beta 7 its back to being sluggish like 10.2.1 what the hell now worrys me for final next week why did it get worse wish i stayed on beta 6

Mines the same as beta 6. No difference here. Try a different wallpaper.

The usage was just normal stuff...facebook...email.....this site.... The usage list has no bearing on my battery's drain..... Its the drain during standby that kills my battery....

Check things like iCloud and email accts. Those tend to hang up causing background drain.

Good evening,

How is the Apple News App? Is refreshing still slow like in beta 6? Was almost unusable due to stories not refreshing correctly.

Thanks!
Scott

I'm on Beta 7 and my News "For You" page just updated in under 3 seconds. About on a par with previous experience.

I would try resetting your network settings. Is it very slow on both wifi and cellular?

I've installed the PB today, since I waited for a more stable version. The only negative thing I have to say so far is the task switcher animations sometimes get choppy. Other than that, smooth here.

Do you guys think the Final Version of iOS 10.3 will be released this Friday March 24? The CodeRed iPhone is going to be released on friday I would think it comes with iOS 10.3 preinstalled on it, Opinions?

Why would Apple update iTunes with iOS 10.3 support if 10.3 wasn't going to be released this week?
