How does iOS assess battery usage?

I suspect that my iPhone 6 Plus isn't giving me the battery life it should. What I am finding is this:
When going to Settings > General > Usage > Battery Usage, I find that iOS will give me an accurate standby time. However, the Usage time is way, way too high. I could use the phone for thirty minutes, and it'll record almost two hours of usage time. Now, I understand that iOS may talley up the amount of time the phone spends collecting emails and other data from other apps, but still, the usage time it gives me is unreasonably high.
Per Apple, I should get "up to" twelve hours of web browsing. I'd be lucky if the phone lasted for six hours of web browsing.
Am I missing something here, or am I dealing with a phone with a bad battery?

iPod touch, iOS 6.1.1
like Diavonex stated, you could use an app created to check the battery percentage
but remember, google is your best friend =^)

HomeKit - How does iOS device control accessories remotely?

Hi,
How does iOS Homekit apps communicate to the accessories remotely?
What is the role of Apple's Home Automation Protocol? Very minimal details about home automation protocol is available at developer.apple.com.
Can you please provide details about 'Remote communication' and 'Apple's Home Automation Protocol'?
Thanks in advance

Hey, I am also doing the same project. Have you got any solution. If you have any can send me your VI. Otherwise contact me after few weeks as I am going to finish my project in 3 more weeks.So, I can send you my VI, hopefully I will complete by then.

IOS 8 battery usage feature

just found this in settings & looks brilliant and useful! games take up most battery usage but there is home & lock screen battery usage & it's quite high is that from me just pressing the home key to wake my phone up or is when I go from screen to screen of my apps on my home screen? it takes up a lot of battery! also if it's games that take a lot of battery if I force close them & stop them running in the background will that cut the battery usage down?

I heard about this before iOS 8 became available and wanted to try it.
I found this in the Settings / Usage menu. On my iPhone 6, it says "Battery information will be available after using the iPhone for a few minutes". And doesn't update.
Does this work as expected for you? Did you see that message at all?
Thanks very much.

Top right battery icon does not show battery usage

So over the weekend I did not charge my iPhone, because the icon always said I had full battery life. I believed it because I never made a call, listened to music/video or surfed the net. It basically stayed in sleep in my pocket both days.
I get to work monday, pull it out to listen to music and I get the full screen battery icon showing the battery is dead with the plug and lightning bolt icons under it, then it turns off on its own. If I turn it on again, same deal.
I get home, hook it up to my PC and charge it, it works fine.
Today i've been listening to the iPod all day and surfing the net on EDGE and the battery icon in the top right shows full battery. To test I turned WIFI on for the past few hours to check and it's still showing full battery.
Basically just the battery icon in the top right isn't recognizing the battery being used. My Usage stats in Settings are also blank for Time Since Last Full Charge.
Background info:
Refurbished iPhone bought directly from ATT, came with 1.1.1, immediatly upgraded to 1.1.4
I've tried hard reboots.
I keep push e-mail and WiFi off at all times. WiFi comes on very rarely and only for short amounts of time.
I keep the phone connected to my PC overnight, but the PC does not go into any sort of sleep mode(ruling out not charging overnight)
I'm going to go home tonight and restore the phone to see if that helps, but I wanted to see if this is hardware related or software. This just started this weekend and i've had the phone for a few weeks now, and other than some short battery life at the beginning when I would keep wifi and push e-mail on a lot, or the random Safari closings, no other issues.

DOrk4L,
Have you tried re-calibrating the battery? To re-calibrate it, let the battery drain completely and then charge it fully. You should see correct battery usage after that.
Hope this helps,

How does iOS 7 run on the iPad 3?

I am considering the option to upgrade to iOS 7 on my iPad 3 (this is the model with RetinaDisplay, but has the old dock connector.) How does it run? Does it create lag? Will this affect the way I use my iPad, like the keyboard?
Thanks!

I'm running it on a iPad 3 and so far no issues. I had one game that the first time I used it lagged real bad for about 10 seconds. I closed it then opened it again and it has been fine since. I'm not a typist so as for keyboard lag it's not there for me but some on the blog say theirs lag. Before you upgrade I strongly recommend you look really hard at the new icons on Apples product pages. Most complaints I see are related to that and the colors/ contrast of the Apple apps pages. Lots of plain white backgrounds. Some people on the blogs report severe issues and some will likely only be correctable by a later update. Keep in mind that most help blogs like this one only see people who are having issues. That doesn't mean that the update is bad but that said I would be upset if I upgraded and had some of their problems with my pad.

How does IOS choose what IPv6 source address to use?

I have a 3750X with IOS 15.2.2E.
I have multiple IPv6 addresses on the default VLAN (VLAN 1):
ipv6 address 2001:470:...../64
ipv6 address 2001:470:...../64
ipv6 address 2605:A000:..../64
I have one default IPv6 route:
ipv6 route ::/0 Vlan1 FE80::.....
S ::/0 [1/0]
via FE80::....., Vlan1
My question is: when I issue a ping from the 3750X, how does the switch choose what source address to use?
Currently, it seems to use the 2605:A000 address, but why?
Can I change this behavior?
Thanks!

OK,
How about my second question: Can I change this behavior in IOS?
Thanks!

How does iOS 7 run on the iPhone 4S?

Hi,
I have an iPhone 4S (64GB) running 5.1.1 and would like to know how iOS 7 actually runs on the 4S. I have read so many conflicting reports about iOS 7 on the 4S that I do not know who to believe anymore. I never updated to iOS 6 because of the much published “WiFi greyed out” issue that haunts the 4S. From what I read, this is ongoing with iOS 7 with no fix in sight as it's hardware issue as a result of shoddy build quality.
My only previous update experience (from one version of iOS to another) is with a 3rd generation iPod Touch which after the update to iOS4 (which broke the video app) and then iOS5 (which at least fixed the video app) is only good for playing music. It so laggy that doing anything else with it is basically impossible.
The iPhone 4S was designed for iOS 5 and not iOS 7. Is the iPhone 4S’s processor up to the task of running iOS 7 without any glitches and lagging? I'd rather stay on 5.1.1 than having my user experience tanked by a phone that it not quite capable of running the new version of iOS problem free. I am not one of those people that MUST have the latest version of iOS not matter what. My phone working reliably (and having WiFi & Bluetooth connectivity) is much more important than a flashy (some would say ugly) new iOS. The only reason I am considering upgrading is for the new call/sms blocking feature. I know Apple says that they are compatible, but they also said that iOS4 & iOS5 will run on a 3rd generation iPod Touch and it just does not....
Any comments and suggestions will be greatly appreciated.
Tyler

Hi Tyler
is the other 4S user frequently cleaning the tasks that run in the background?
- if not: double push the home button and swipe away the unused 'running"-Apps.
(this is also new: it used to be push and hold - then press the X. Now simply swipe them away)
I also have an iPad 1st Gen with iOS5 and find it very helpful to restart it once in a while. This also helps to increase the performance and reduces crashes.
Ok, I have to admit that my 4S also froze in the past, but maximum once in a month or two. Usually this happened when I tried to do to many things at the same time.
However what I experienced, that the camera App crashed more often when trying to shoot multiple HDR pictures. I believe it is due to the computing, which has to be done by the phone, since HDR means, shooting 3 Pictures and merging them.
My Battery is, as the phone 2 years old and last about a day in business use. I turn off wifi and BT when I don't need it, further reduce the display brightness. This increased my battery life significantly.
Observation with WhatsApp: sometimes I need to close and reboot it (in the task manager), but I related this issue rather to the App than the iOS.
Good luck

How does iOS 8 handle photos. I am very confused...

So since updating to iOS 8 i am bit confused how the photos work... BTW I did not upgrade to iCloud Drive and won't until yosemite comes out just FYI in case this all makes any difference, I assume it doesn't.
(BTW I know lots of people hate the new photos app and how it works but pls I am not writing this to hear your issues with it, I am just wondering how the new system works.. what are the rules)
Since camera roll and photo stream are gone, now both of those are bundled into Collections. I get that.
So now if all pictures (in could and local) are in collections I am assuming now everything that is in the cloud doesn't expire after 30 days like it used to? I mean it wouldn't make any sense because how the **** would I know what's in the cloud and what's not, unless I open each picture individually and see if it has that heart icon or not. If images start disappearing from photos app I will be ******.
So far I figured that if it has a heart icon it is local image (stored on the device, if not then its in the cloud). Speaking of the heart/like icon... what a **** is the point of it? Why would I like a photo that I took myself and only for me?? Has to have some purpose of it's existence... and why do local images have the heart icon and cloud once do not?? So confusing...
BTW another thing i noticed which is really frustrating... If i take a picture with my phone, the pic appear on my iPad too.. Fine.. If i delete the picture form my phone it deletes from my iPad as well.. Fine all good.. However if i take a picture from my phone and after it shows up on the iPad, I delete it off the iPad it still stays on the phone... Seems stupid.. If they are trying to do with photos what iTunes match does with music I am all for that but keep all devices synced.. Isn't that the whole point of having recently delete folder in case you do change your mind???
I am not gonna proof read this wall of words so excuse typos and spelling as I am writing this off my iPad...

I Understand what you mean by confusing.... I discovered that the photos do delete from the Recent collection from both iPad and iPhone 5c after the update. I had to click around in order to understand what was going on. i alreday made a fave album for the favorite photos then after the update, I had to do the heart which is unnecessary, as you mentioned. Why like or fave a photo? I'm sure people will voice their opinions about how the photos operate. I have other issues to address and hope that thIngs will iron out. I like the old version of the Photo Stream, I could take a picture with either my iPad or iPhone and instantly the picture would be stored until I edit and add it to an album. I DO MISS that feature. I hope iApple will make changes back to the Photo Stream. What you could do is contact the iApple support and offer a suggestion.

IOS 4 battery usage (again)

I have a new (actually 6-month old) 3GS which is running iOS 4.1, whereas previously I had an iPhone 3G with iOS 3.1.3. I do have push notifications enabled (yet receive very few) and only check email manually. Am not connected to a Wifi network (although Wifi is on, bluetooth is off; 3G is off as well). However, what I've noticed is a persistent, albeit slow battery drain when my phone is in its locked state (perhaps 10-11% overnight). I don't recall this happening on the 3G / 3.1.3.
Is this to be expected? I'm getting close to 5 hours of use on my iPhone 3GS with all activities (internet, light phone use, etc). Is that what one can expect?

Never mind, I see there is already a huge thread on this topic: http://discussions.apple.com/thread.jspa?threadID=2474499

Ios 8 battery usage

JJust updated to iOS 8 on my 4th gen ipad. It's now eating my battery. Anyone else notice this? Don't have stats yet, but it's never done this before.

I updated to ios 8 on my iphone 5. my phone used to last a couple to several days with the limit use I give it. 4 hours after updating to ios8 my phone was down to less than 8%. I recharged it and again the battery lasted around 4 hours on standby. I tried every posted solution even restoring to factory setting and reinstalling ios8. no change. contacted apple and the tech worked with me to go through the steps to install as new. no change. I can watch the battery drop one % every couple of min. Techs claims I need to send my phone in for repair. worked fine up until I upgraded to 8. I think the solution is to upgrade to droid. anyone want a couple of iphones and ipads. I give up.
IBM products never gave me these problems.

How does one track license usage?

Our customers purchase some number of licenses, and sometimes we run out.
However we don't have any details, except what we can clean through logging.
What we want to be able to provide:
- What people/sessions & reports are currently using licenses?
- What people/sessions are waiting for a license?
- What is the best way to provide a waiting for license timeout (maybe 5 minutes), without requiring that reports be generated in the time period.
thank you.

When you "run out of licenses", you queue waiting for the next license to become available, however there no visible difference between this situation and a long running report.
1) We'd like to be able to track who is using a license (so we can potentially kill their report thread), which means we'd want to be able to track by session each license being used. Now we can enable enough debug to sort of track this, but we cannot relate it to a session, and the debugging output is pretty extreme. We track who is running a report externally, but we cannot tell if that report is running or waiting for a license.
2) we'd also like to be able to reservere a few licenses for executives etc.
Our application would separate our users into one or more classes, and then by looking at what sessions have a license, we can decided if we allow the report to run or just tell them there are not enough licenses right now, try again.
