IOS 8.1.2 safari battery usage

Ever since updating to iOS 8.1, my iPad battery life has declined to the point that i have to recharge every day.
the only things i use my iPad for are safari, Facebook, google play books, stock music app, and youtube.
I've checked battery usage, and safari has 90 percent of the battery usage.
i have also factory reset the device, tried to keep screen brightness below 50 percent, and shut all apps, but that makes no difference.
i have also updated to iOS 8.1.2, and it made no difference.
am also considering a nexus 9

i have same problem, than battery percentage jump from 60 to 45 e in this way my problem is very bud. ios 8 last update is installed on my iphone 5. i think that it is a bug software, and i think this because i called apple support and diagnostic realt time with operator say that my battery life is better. and after home button bug fixed with ios 8.1 now i have this. this ios 8 is the worse update ever.

Upgraded to ios 5.1 now extremely poor battery usage any ideas?

Upgraded Sunday to ios 5.1 now extremely poor battery usage - any ideas? Have tried a few thinks - nothing seems to make a difference?

Downgrading is not supported. What IS supported is searching though the forums....there are a number of excellent posts with great suggestions on maximizing battery life and troubleshooting battery issues.

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?

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.

Excessive battery usage since IOS 8 update

Help!!!
I've a iphone 4s & have recently completed the IOS 8 update on my handset
Ever since completing this, my battery 'usage' has been excessive & my phone never lasts more than 7-8 hrs even though for the majority of this time, the handset is locked & in my pocket at work!!!
Prior to this update, I'd return home from work with at least 30-40% battery life but now the handsets died before I finish my shift!!!! Frustrating is an understatement.....
Another example is after charging fully this morning, my handset says its been on standby for 2hrs 5 mins yet has been used for 1 hr 45 mins..... I've been asleep for most of this time so how does that work?!?!
Please can you provide me with an idiots guide to reducing this ridiculous level of 'usage'
Many thanks for your help in advance

my phone not working properly after updating to that too ,is there any way to get back to ios 7 ???

Does SMS relay iOS 8.1 cause extra iPhone battery usage?

I was messing with both SMS relay the other day and noticed that my battery drained almost twice as fast..
I was also messing with handoff and basically just testing the new integration features between Yosemite and iOS8.1
But my question is about SMS relay.. Does anyone know if this will us up more iPhone battery than if I wasn't using SMS relay and just SMSing from the iPhone itself?
Does SMS relay work via bluetooth? Could this be a cause for extra battery usage? It could be possible that I was jus using my phone a bit extra that day but I just want to make sure as I have SMS relay turned off for now, don't want battery life dropping..

I had the same problem. I realized that it had everything to do with my calendar app. My iCalendar was having a difficult time fetching information from my Outlook and Yahoo Calendar. Causing my battery percentage to decline at a very rapid rate. (50% in a 4 hour time frame). I resolved the problem by going into my Settings >" Messaging , Contact , Calendar" Setting > Clicking on one of my selected Accounts ( Outlook or Yahoo) and turning off the Calendar Sync. The problem seemed to go away after doing this. Now I'm only using 4% battery life in a 4 hour time frame in StandBy Mode. Well I Can only hope that this will help resolve the battery drainage issue. Good Luck ....

IPhone 6 Battery Usage setting not working.

When I go to my setting and check my Battery Usage setting it states: "Battery information will be available after using iPhone for a few minutes". I've been using it for hours and I get the same response when I go to the setting. I've turned off my phone multiple times to see if that would resolve it, but it hasn't. Is anyone else experiencing this behavior?

Hello.
I have the same problem. iPhone 5, iOS8.0.2, used for a few days - still no usage statistics, only "Battery information will be available after using iPhone for a few minutes".
I tried restore iPhone (DFU) without restoring backup from iCloud/iTunes, resets, hard-resets, erase all settings, drain battery to 0% and charge to 100% overnight etc. - nothing helps.
I wrote to the Apple about this problem.
Here is the page that you can use to contact with Apple and report a bug - https://www.apple.com/feedback/iphone.html
Please, give the title of "iOS8 battery usage statistics not working" (or something like that), choose the "Bug report" and describe the problem. Perhaps it will make that Apple will eliminate this problem in the next version of iOS. More report - greater chance.
Regards

IPhone 6 Battery Usage function not working

Battery Usage feature continues to read; "Battery information will be available after using iPhone for a few minutes" even though I have now had the phone and used it for one week. Using iPhone 6, 64G, IOS 8.0.0.(no iOS updates have yet been applied)
A few days ago I attempted some suggestions posted by others. One of those was to let the battery drain to zero then fully charge. This had no affect on the Battery Usage feature. Another suggestion that i tried was to close all open apps on phone, then shut down phone and then turn back on. This did not resolve the Battery Usage issue either.
Is apple aware of this issue? Any help would be appreciated.

Iphone 4s IOS 7.0.4 update battery drain issues

I hope this gets to apple in regards to the issue of the battery drain. I have been following several discussions for the past couple of weeks and everyone seems to have some type of idea on what the problem is. I'm not a service tech or gadget know all, but I have been performing several "Nonscientific" test to see what is draining my battery.
I have a 4s that has always had good battery life. It seemed to run consistent to what was detailed in the product specs. I would only need to charge it every other day on limited use or the next day with heavy use. After updating to the latest update (IOS 7.0.4), the battery would drain in less than a day on limited use which is a couple of text, couple of email checks, 3 to 4 phone calls at less than 10 minutes each - no internet searches or game play.
So, after reading everyones suggestions in the forums and trying them, the battery still drained just as fast, if not faster. I read a post somewhere regarding “Bluetooth” constantly searching. So, I saw mine was doing the same. Someone replied to that person that it should not be the issue, as it does not use much power to run its task. (I found they were wrong)
Here is my nonscientific test, but a good one. (for the record I had nothing on in the notification center, Do not disturb off, only thing on in Privacy - location services was google maps, Siri, Yelp, and Find my phone; iCcloud was off; background app refreash was off; email fetch data was off; everything else was off)
Day 1 - I fully charged my phone several hours, I unplugged it at night before going to bed, did a hard reset to make sure every app was off, and only opened the settings app and made sure the Bluetooth was onand searching. I checked my phone 6 hours later and saw the battery drained from 100% to 56% with no usage other than just being on and in sleep mode. That would mean it drained at 7.3333 % an hour. Some would say that acceptable. - Its not when there is no usage. The battery would die in 13 hours with no usage.
Day 2 - I repeated the test (as above), but turned off the bluetooth. I checked my phone 6 hours later and saw the battery did not drain at all. I started with a 100% and battery was still at a 100% with no usage other than just being on and in sleep mode. I opened a couple of apps and closed them to prevent them from running in the back ground and noticed I lost about 2% of charge after usinging it checking an app or 2. I put it back to sleep mode and checked it again in an hour and saw it only drained 3% down to 97%. Very acceptible.
Day 3 - I repeated the test, but during regular day hours with limited use of the phone (with bluetooth off). I was back to getting close to a normal battery drain I was experiencing prior to the update. I know that IOS 7.0.4 uses a little more battery power to run as it has different features and abilities, so the battery drain was not like it was before, but a lot better.
So, my experiment concluded to me that the new update is causing the bluetooth searching to run in the back ground continuously and causing the battery to drain unacceptably fast on my phone. This is a program issue that can be fixed by Apple. I find it unacceptable to have to control my bluetooth manually, as I never had to do it before and I shouldn't have to do it now. I hope Apple will fix it soon. I‘ve been a apple product person for years, and enjoy the products, but lately they have been not been satisfactory in the phone business. I have been playing with a samsung galaxy thats looking very promising, if apple doesn’t fix the issue everyone is having, they will loose business to competitors.
Please fix the issue!

Hi Folks,
iPhone & iPad2 battery drain issue SOLVED!!!!!
I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......
Devices;     16GB iPhone 4 with IOS6
                  16GB iPhone 4S with iOS7.06
                  32G iPad2 with iOS7.04
On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).
I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......
Hopefully this will be useful to others in this thread ..........

Get the battery usage of single application programmatically in ios7 and later

Get the battery usage of single application programmatically in ios7 and later

Not natively with iOS. you might check the app store for a battery monitoring app, but to be honest, it you find one that claims to be able to do this, I'm nopt sure I would trust it.

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

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,

Home & Lock screen battery usage 47%

Iphone 5 IOS 8. In checking the new features on IOS 8, I noticed that the Battery Usage for Home & Lock Screen is 47%. Battery replaced on 09/12/14. Is this normal?

I have been having this issue off and on since the 8.0.2 update. I seemed to fix it, then 8.1 brought it back... thought I got it in order again, and mostly, it runs ok..then suddenly the battery just drains like crazy! Granted... my phone is about a year old, so probably is about time to replace the battery anyway... but it's this unpredictability that is bothering me! I almost have to keep it plugged in at night now because I use it as an alarm clock, and a couple of times, the battery has nearly totally drained within just a few hours of sitting there! Last night, I know I looked at it in the middle of the night and it was at about 85%, but then this morning, suddenly, it had dropped to less than 10%! Same thing earlier this week. It was sitting on my desk by my computer and it had been fine and suddenly the insufficient battery symbol was flashing! If it were just the battery going bad, I would have expected it to consistently drain, but it seems fine some days.
One thing I did consider is that we have some apple charger cables and some cheap, third party ones....and sometimes it seems that, while they seem to charge the phone, that the charge doesn't hold as well... but it isn't consistent either. I do know that the colorful ones target sells are NOT good! they cut off some of the sound when plugged in (video, text alerts etc), and if you try to use it as a data transfer cable to your computer, the transfer seems to get stuck.

IPhone 5 Battery Usage Spiked!

For the past 10 days, battery usage on my iPhone 5 has spiked! I've gone from charging it once a day to needing to charge it three to four times a day. This morning I watched battery life percentage go from 97% to 36% in four hours. I did not make any calls on it during that time. I have tried some experiments to isolate the problem.
     The battery seems to deplete at the same rate if I am on my home WiFi or AT&T's LTE but I have been leaving it on cellular a lot lately becaue the LTE service is fast.
     I see that using bluetooth to stream music from my iPhone to a speaker drains the battery more quickly but lately it drains at a more rapid rate.
     I've turned off a few notifications I don't need with little effect.
     I do have a few weather apps that I have been accessing recently (I live in the midwest) but I have done that with other iPhones in the past.
45 days ago I had to restore the iPhone back to factory settings and start over again because I could not join any wifi network the the entire system slowed. Apple thought it was corrupted software so I had to start over. Today I do not seem to have those problems but battery life is signficantly reduced.
Does anyone have advise as to what do to next other than take it in to the local Apple store for tests?
BTW I have plenty of space left on the iPhone and am running IOS 6.1.4.   Come to think of it, this issue occurred around the time I installed 6.1.4!
Thanks in advance for your advice.
Jay

There can be many reasons, but usually, it's an App issue, not a phone issue. For example, if you have an exchange mail account, it could be constantly trying to push mail. That will certainly drain a bettery fast. If you check you mail account and you see a spinning circle, which doesn't stop, that could be your problem. Often, either rebooting your phone or deleting, then re-entering the mailbox will resolve that. You could also have apps running in the background. Do you routinely fully close apps you are not using. To do so, double tap your home button to bring up the task bar (recently used apps). With your finger, hold it on any of the apps until they jiggle and you an on the upper left side of each app. Touch the to fully close the app.
Finally, during the set up of a phone or the upgrade of iOS, some things don't always port over correctly. Restoring the device and setting it up again, often solves this.

IOS 4.x camera high cpu usage bug

Ever since upgrading to iOS 4, I've noticed that periodically my 3GS's CPU usage is higher than normal. Instead of 97% of the CPU or higher being idle, only 85% is higher. This causes the battery to drain at about the same rate as if I'm constantly playing music, so the phone won't last the day. This problem persists under iOS 4.1. The CPU usage can be seen by any number of free apps in the App store, simply search for CPU.
Using an app that uses the location services or turning airplane mode on and off will temporarily drop the CPU back to the normal idle rates, but the problem will return within a few minutes. The only permanent fix is to reboot the phone.
For the longest time I thought it was related to using location services, but I've finally tracked down the problem to using the camera. If any app uses the camera (camera app or 3rd party app), the problem has a high probability of occurring within the next few minutes. If I never use the camera, the problem never occurs. I've pretty much confirmed this by having weeks go by without seeing the issue, then immediately seeing the issue after using an app that enables the camera (such as a bar code reader).
I've reported this to Apple a number of times and they keep either ignoring it or asking my for log files over and over again. Either they can't reproduce it or they're not even trying to reproduce it. Considering how easy it is to reproduce and the fact that I've seen someone post in the battery life thread reporting the same exact thing, the later seems more likely.

Assume you've read threads on draining batteries and random shutdowns. You may be on to something.
My 3GS shuts down now randomly but usually once the battery hits about 30%...the part that sets it off every single time is opening any app that uses the camera!
Once this happens it won't usually come back on without power tethered.
Would love to see Aplle acknowledge this issue and put to rest all the moronic responses on here telling people to stop using their phones as they have been for the last year and turn everything off to save battery.
