iOS 8.1.2 Battery Life

Here's another screenshot of my most recent battery usage

Facebook / Twitter is still on there however that's only because of last 24hr activity. I spent more time on Safari browsing on WiFi and using Snapchat a few times.

I'm literally seeing the Battery Percentage tick down in real time so quickly. I'll be on a website reading something and it'll drop 1-2% every minute or so.

I'm convinced there's something wrong with my battery, just wish Apple would sort this out!

Still my mail app and settings app high usage. What can cause this? They are barely being used. Phone will not go standby either.

You believe he lost most of his charge because his battery is "unsettled"?

No, the battery indicator and the amount of energy in the physical battery are out of sync. this happens every iOS update (At least for me and others)

People are questioning this comment because the battery doesn't settle. What happens is the charging electronics needs to see 100% and then 1% or so to calibrate the phone's battery meter and display. It only needs to be done ONCE, not several times. If it is not done, meaning calibrate, the phone uses that calibrate meter to shut off too early .

According to Apple, Dell, and others this calibration could be once a month at the most or less if not needed. Doing it more often, only kills ( reduces the useable hours) the battery since Li-Ion batteries have a finite full drain capacity cycles, but a lot more partial drain capacity cycles. I rarely calibrate less than a few months, but I also recharge every night, regardless of the battery meter.

It's a far better practice to recharge at 50% than waiting until 10%....unless you want to do a recalibration.

Another thing: resetting or hard reset after an update is unnecessary. Apple does this as part of every update. Your phone completely shut down and reboots during updates. You can see it and you know it since you must enter a password since the Touch ID does not work after a reboot.

Now if you have an errand App for some other reason, then a reboot will kill it. That is a different story.

But these myth antics that people do after an update are just that. If you thought it really helps, wouldn't you think Apple would make it an auto part of the update process? Well in fact they did. a long time ago.

Just my input. All these full drains, multiple times, is just shorting the usable charge capacity of people's battery.

I was just explaining what I meant by settling is that the battery indicator and the physical energy in the battery get out of calibration.

There are a lot of issues Apple could automate in every iOS update like resetting all settings, network settings (which seem to fix a LOT of issues after an update) but they don't. So, I don't know what to tell you. All I can say is that every iOS update my battery reporting gets out of sync and corrects. It may or may not be nonsense but I'm not alone in seeing battery drop rates increase after an update.
 
No issues at all with my Air. The battery performance HS stayed the same with basically every iOS release since I bought the thing.
 
Battery life on my Air (first gen) is great, I used it for 7 hours and it still had half the battery left. I have the screen a notch or two below half brightness and mainly use it for web browsing using Chrome.

Battery life on my iPod touch is a little less I think, I don't use the screen too much and have the brightness quite low and I got 20 hours with just under half the battery left showing.

Both of these devices were purchased within the past three months as well.
 
Here's my usage with my 6+ running on 8.1.2, so far I'm happy with battery life. On my 5s on 8.1.1 with a mophie air case I would still have to recharge daily

If that is what you meant, that is fine. I was pointing out that doing a calibration multiple times, back to back, is pointless, and damaging to the battery's life span.

I really never do it after an update, and under 8.1.2, I getting near 11 hours of usage on my 6. And 14 hours on the Air 2
 
Here's a first..... I updated this morning to 8.1.2, the battery was draining more than usual, it was down to 96%. So I did a reset (home+power buttons) and when the phone booted back up, I was back to 99%.
Has anyone ever seen this happen?

So what type of usage are you referring to on the iP6? "Usage of xxx hrs" doesn't mean a lot without knowing what type. Like audio is spec'ed at 50hrs so if you are only getting 11hrs in that case then its horrible. :)

Dude how on earth do you get 11 hours usage? Can you post some screenshots if possible?

I'm tempted to take back this piece of crap seeing as I can barely even hit 5 hours usage!
 
I plugged my iPhone 6 on 8.1.2 into iOS Console and noticed every time i lock my device or leave it for a while "mstreamd" keeps restarting, wouldn't it make sense for the process to shut down and stay off until unlock? why would it shut off they start back up instantly every time?

I hope Apple does something to fix the battery issue in build 8.1.2. There is quite a long thread concerning major battery drain being seen on the 8.1.2 build and I'm sure Apple can fix the issue quickly with the release of 8.1.3. And no, I'm not a normal "battery issue" person and if you read the chain, you'll find numerous people having a major drop in battery on both the iPhone 6 and the 6+. PLEASE APPLE, look at the "iOS 8.1.2 Battery" chain under the iOS 8 tab here on Mac Rumors!! Thank you

While it seems that a few people have had some battery issues after the update, it doesn't seem all that major or certainly widespread, and not really out of the ordinary as far as what some people experience with all kinds of updates.

That's ok for you to believe. We're all entitled to our own opinions but I can assure you, there is a major problem with my battery drain on 8.1.2 and plenty of others have the problem as well. Those that went back to 8.1.1 noticed an immediate increase in battery life thus leading some of us to come to the conclusion that there is indeed an issue. I'm sure Apple is aware of it and I just asked that it be addressed.

And as I mentioned, there are definitely people that have battery problems, as there often are with pretty much any update. What I'm saying is that those battery problems don't really seem to be widespread or major (even if some of the people that are having them are experiencing noticeable issues). Now, there might be something off in the update that somehow affects certain devices under certain configurations, but that's hard to say for sure and hard to necessarily say that Apple is specifically working on a fix for something like that that would be part of a point update before 8.2 (or part of 8.2).

Anyone know how I could achieve this on my air 2?? Definitely something fishy going on. Brightness is set at about 40% (auto)

Yeah, plug it in and let it charge a little but not up to near 90% . I noticed yesterday on iP6 I had 1 day 12 hr stdby, 7.5 hr use and was down to like 1%. Plugged in when went to bed and in a little while looked and it was back to 50% or so but the "this phone has been plugged in" message didn't appear. I disconnected just to see what it would do and it was like it was still going from previous charge. So apparently there is a bug in iOS 8.1.1 not reporting 100% of the time that the device was plugged in since last charge. I suspect some of these high reported screenshots could be due to that issue.

I think everyone here should have a look at this. http://www.scottyloveless.com/blog/2014/the-ultimate-guide-to-solving-ios-battery-drain. Btw in my own unscientific research I have found that having Auto Brightness can drain the battery. Sometimes I am in a fair lit environment and my brightness will be at 100%. YMMV

Auto brightness is supposed to detect ambient light and adjust your screen brightness accordingly. I can understand where you are coming from by saying it doesn't do it correctly all the time and may end up draining more battery than necessary but the same can be said for you as a human being.

Let's say you are in a room and you set your brightness manually to 50%. You could go into another room and then forget to adjust it because frankly we tend to turn brightness up and down based on if we can see the screen or if its too bright and hurting our eyes.

The auto-brightness system is a bit more advanced than us. I keep auto brightness on but will try a manual approach at 25% and see what happens.

I recall Anandtech (or Arstechnica, don't recall which) finding that cranking the brightness to max can cut the battery life by nearly half. Not sure if the auto brightness affects things nearly as much as the actual settings.

I have finally decided to stick with 8.1.2 and now have no choice to go back as Apple is no longer signing 8.1.1. I must also admit that I may have been a bit paranoid about my battery drain. I've been on 8.1.2 for the past two days and have been getting better than 11+ hours of usage time per day, although I don't have ApplePay set up as 1 member suggested may be an issue. After reading the above blog and watching my Ip6, I just may be one of those "over obsessed users" worrying about battery life too much. Thanks though to thegrants for teaching me how to restore a previous build. Time to get back to the real world for now.

Sounds good. So what type of usage is that 11hrs? I typically get around 7-8hr on iP6 (8.1.1) using mostly web browser, email and several apps for various things. Of course when playing music a lot more. Almost 100% on wifi most days.
