Ios 7.0.4 battery issue and DFU mode restore

Hi guys. My iphone has an issue with its battery since i updated my iphone from ios 6.0.2 to 7.0.1 until now ios 7.0.4. I have tried many things, like turn off parallax, background app refresh, location service, mail to fetch, air drop, bluetooth, celular data, delete icloud back up from iphone, delete email acount, reset all setting, restore from back up, restore and set it as new phone, but all thoose things didn't help. Now I loose 1% for 3 minutes. Before thoose update i loose 1% about 6 minutes.
But i have been oberseving so far to know what is causing this issue. This morning i did the DFU mode restore, exatcly not recovery mode restore. After DFU restore completed, i watched every each percent of my battery begun increases to 4,30 minutes while using internet via safari. After that i restored again from my itunes backup, and the battery back to 1 % / 3 minutes while using safari with the same setting. This is first time my battery increases, and my first time i used the dfu mode restore. So far i always using itunes restore.
I guess there are something make the battery drained. I think that icloud data and email account causes this issue. But when i try delete manually my two email accounts and icloud data backup. My battery still 1% / 3 minutes.
So, are you guys have some experiences? Any ideas?
Thanks before, regards from Indonesia

I'am sorry. I'am using ios 7.0.4 now. I forget to set it before i send that post

How do I download from icloud to phone? Had battery issue and bought new one

How do I download my contacts, apps and all info from iphone to my phone? I had a battery issue and was told that buying a battery and resetting phone to original state may resolve it. It seems okay now, but I need to understand how to restore the info that I backed up on last night. Thanks.

If you want to restore from and iCloud backup you have to go to Settings>General>Reset>Erase All Content and Settings. This will erase the phone. You then go through the activation screens again and when given the option choose Restore from iCloud Backup (see image below). (Connect your phone to and external charger and wi-fi as this sometimes takes a while to finish.)

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Activating an iPad and getting a message that the iPad is currently linked to another apple id, need to sign in to set up the iPad. I have put the Ipad into recovery mode and done a restore following the Ht1808 support instructions and tried to do a DFU mode restore but still get the activation message after the restore.

My iPhone 3GS restarts repeatedly. Cannot be restored even in DFU Mode Restore.

My iPhone 3GS crashed and restarted on its own while running the Pandora app while plugged into a USB and charging. After it would finish starting up, it would say "activation required", as well as showing "no service" where there should have been service available. It would then restart after about 30 seconds to a minute. It would do this repeatedly in an endless loop of restarts.
I tried to do the "DFU Mode Restore" by holding the power and home buttons for 10 seconds, then holding the home button only until it connected to iTunes. The phone did have the black screen, and iTunes told me that the phone was in recovery mode and needed to be restored to be usable. The restore seems to complete, but in the end it fails. It says, "the iPhone "Iphone" could not be restored. An unknown error has occured (1)." It just leaves me with a screen showing that I should connect to iTunes with a USB cable.
Also, it shows no information on the phone in iTunes (capacity, software version, and serial number all show up as "n/a").

BOSD, Battery issues and Heating problem after iOS 8 upgrade

i have upgraded my iPad mini to iOS 8. Ever since I upgraded to iOS 8 am facing blue screen issues and heating problem as well. This is really frustrating even the patch iOS 8.0.2 dint solve the problem. Are you guys listening our complaints. When will you fixing it.

The same thing happened to me on my 2012 Subaru Outback. I'm not sure this will help you since you have a Honda, but I'm posting this just in case.
I paired the audio on my car with my iPhone 6. However, when I turned the car off and back on again, the iPhone would not pair automatically. I had to manually connect the iPhone with the car. Turns out there are two separate bluetooth pairings on my car: one for phone which allows up to 5 devices and one for audio which allows only one device. So I did the second bluetooth pairing for the phone (had already done the audio), and that fixed it. YMMV

IOS 8.1 massive battery issue

Since I've been updating my 5s with latest 8.1, my 5s now facing a battery drainage problem!! Massive! I've been charged full 100% battery and with only 1 hour while playing slight wechat only, it draining like **** until 70%.. And heating like oven!! This never happen before! Even before i've been playing with heavy use of wechat, beetalk, games and video, it still remain 84%.. Now it's draining like water leaking.... iOS 7 is always better 1001% compare to iOS 8.. There is always a new problems!! U guys solved 10 problems/bugs, but again u guys will create 2 to 3 new problems!! What's wrong with Apple nowaday?! Think about to moving on to Samsung!

I'm also seeing something like this. I believe I may have isolated one issue that Apple have verbally acknowledged: Re: Did iOS8.1 fixed the battery draining and heating problem with iPhone 5s?
However i wonder if it's more general. Just a few hours browsing on my phone with very little running in the background uses a lot of battery. I go to use settings and it tells me that Safari has used 45% of th battery in a few hours. This never happened on ios7.
After each release of iOS there is usually a load of people moaning about battery life who don't understand the options of how their phone works but it does feel like there is a genuine issue here. A lot of the noise seems to be coming from iPhone5S owners, I wonder if the more General wifi issues are causing problems elsewhere......
i Don't suspect it will be that long before we see a patch.

I PHONE 5 BATTERY ISSUE AND PHONE SHUTS OFF

MY I PHONE 5 SHUTS OFF REPEATLY AND BATTERY PERCENTAGE IS SHOWING DIFFERENT NUMBERS

I'd just like to say that ahs70's post on Dec 1, 2013 at 1:17am on Pg. 9 worked for me as well: https://discussions.apple.com/thread/5338609?start=120&tstart=0
If your iPhone's battery is acting up you need to determine if it's a software issue or a hardware/battery issue. To do that, after syncing your iPhone, erase/hard reset all data and settings from your iPhone to what it was from the factory as new. This can be found in Settings/General/Reset/Erase All Content and Settings. Then test it out for a day or two. If it's still acting up then it's likely a hardware issue and you will need to get your battery replaced. If your warranty is done than check out this link to get a battery kit to replace your iPhone battery yourself: http://www.ifixit.com/Store/iPhone/iPhone-5-Replacement-Battery/IF118-001#produc tDescription
If your iPhone is now working properly after hard resetting it than it's most likely a software issue. This battery issue only started after upgrading to the new iOs7, so it is obviously related to the update not properly installing itself. What has worked for me and many others is to manually update to iOS 7.0.4 using the full downloaded version of the update which is about 1.32 Gigs.
But first you need to find out what model of iPhone you have, click here to determine if it's GSM or CDMA: http://support.apple.com/kb/HT3939?viewlocale=en_US&locale=en_US
Then go here and scroll down to download the iOS 7.0.4 complete update for your device: http://www.downloadios7.org/download-ios-7-0-4-ipsw-file.html
Then scroll up on the download page and follow the instructions of updating your iPhone manually following the instructions below: "IPSW with iTunes"
And your done.
Problem solved.
I only posted this because it was a very frustrating problem that no one really seemed to figure out a solution for.
I hope this helps.

IPhone 4s - Battery issue and poor voice quality

I had bought my iPhone in May this year. It was working fine till i think a week back battery started to drain quickly at 10% every hour. I have configured office exchange account for mail and accessing global exchange contacts, Google account as exchange for contact sync and iCloud. i dont keep any contacts on exchange, keep in Gmail only. Was Android user earlier.
I read a lot of posts and tried all solutions such as turning off timezone service in location, turn off and delete all email accounts, kept manual sync for emails, ran the battery down till switch off and charging back to 100%, removed apps i doubted could be syncing data in background, turned off locaiton service totally, turned off calendar, turned calendar notifications, turned of iCloud reminder, notes but no effect. Wifi and Siri are also off.
I notice today that I am getting small circle near operator name rather than E symbol (for edge)and at the same time voice quality of person on other end is bad too, can hear small cracking , clicking sounds, voice breaks. Otther person can hear me properly. I get back E symbol in some different place than my desk. I havent changed my desk so thats not a possibility either.
Someone had suggested queued network thread with exchange can cause the issue so Installed System Activity Monitor app but it doesn't show battery graph or which process is taking CPU or network time. Moreover, it shows 4-5% less battery level than on top in disharging mode !!
Used to get good stats of what is eating the battery in my old HTC Desire but iPhone doesn't offer such feature to diagnosis. Ideally should not be required if phone works as expected.
What do I need to do to get battery life and voice quality back? I will try voice again at home just to rule out bad network at work.
Thanks,
Ashish

Well, most of what you did is black magic, and has nothing to do with battery drain. But we have no way of knowing how your battery life is below what you think it should be. What are you using it for, what apps do you have, and how much Usage life do you get (settings/general/usage).

The iOS 8.1.2 update bricked my 4th gen iPad. I can't even do a DFU mode restore - error 4013. The iPad worked perfectly before the update and is 16 months old. Any suggestions anyone - except to shout loudly at the Apple support line?

I set my iPad to do the latest iOS update as per usual - over the air and while on charge. When I returned to it, it was non functional the screen was blank. I reset multiple times and at one point got a red screen. I connected it to iTunes on my Mac and tried to force a restore, but this didn't work - even in DFU mode. I have gotten a 4013 error every time. I've tried different cables and different USB ports etc, but no success. It's a brick.

I have multiple Macs around the house and have tried all of them - all with the same results alas. I've restarted, ensured iTunes is up to date etc too.
On DFU mode - yes - that's it. I have no idea what DFU stands for, but it this mode is often referred to as this. I get the 'connect to iTunes' picture and can begin the restore, but the process times out waiting for the iPad. Apparently, 4013 is associated with a cable problem,, but I know the hardware is all fine.
What I want to avoid is just being told to buy another iPad. That would be totally unacceptable for an error caused by an update to a 16 month old device. There has to be some solution!

[Iphone 5] update to ios 6.0.1 - battery issue, fix please :(

I have already turned off Siri, Location Services, Notifications
After update to iOS 6.0.1, battery drain very quickly
Something wrong with my phone?

My recommendation having tried all the obvious is send the iPhone 5 back to Apple - Wait for Apple to fix the problems and then buy a new iPhone 5.
I have been buying apple products for over 25 years, I never experienced such a fundamental problem.
Battery drain: 100% to 40% in 4 hours - 100% to 10% 12 hours overnight on standby - with wi-fi off (installed with the same Apps as the 4s with lasted 3-4 days in general use.)
Apple support are either very helpful, or totally dismissive... this morning I was offered "12 hours use is acceptable" as a final word from Apple Support.
The phone is on its way back to Apple, and I'm happily back on my 4s
This is the first and last time I break my purchasing rule when buying from Apple, 'never buy the first version of any Apple product - wait for them to get it right.

2.1 Battery Issue and WiFi

I updated to 2.1 when it came out and overall quite happy with it. But I am getting very mixed results on battery life.
From morning through arriving home from work the battery stays nearly fully charged. Checking email, running a few apps, watching a little video or listing to audio doesn't make much of a dent.
However once I get home the battery starts a fairly rapid drop even though I'm not using it much at home. The only difference I can see is that a home it connects via WiFi (rest of the day no WiFi is available).
Anyone else with battery issues seeing a similar pattern?

My phone lives in range of wifi most of the day, at work or at home.
I have 3g off because I don't live in a 3g area. I turn it on when I drive to the city.
On days when I'm not on the phone a lot, I get easily a day an a half out of the phone. I'd get longer, but its so darned addictive, and I use google reader a lot to follow a lot of RSS threads, and listen to music, and read my mail.
Another poster above says wifi depletes the battery. I seriously doubt this. The wifi radio uses far less power than the 3G or GSM radio. Its just so much more pleasant to use a fast reliable connection than a flaky slow one, that most people probably use the device more heavily on wifi than they do on 3G.
You are correct in your observation that the last 25% of battery goes a lot more quickly than the first 25%. That is a function of the less than perfect technology used to measure battery capacity of Lithium Ion batteries.

Can someone explain what recovery mode and dfu mode are?

title says it all.

The main difference between DFU mode and Recovery mode is the iBoot bootloader. iBoot tells the iPhone/iPod touch/iPad what to do when it turns on, eg. load up iOS version whatever (for me, still 4.2.6 on my Verizon iPhone). When you upgrade your device's firmware, it goes into recovery mode.That way, iBoot can make sure you're flashing into a firmware that's equal to or greater than the current version of firmware you have installed. When you enter DFU mode, there isn't this limitation, so you can flash any version of iPhone OS/iOS that you want, provided the device is compatible with it and Apple is still signing for it.
If this answered your question, tell me. If it didn't, well, tell me and I'll add more!
Hope I helped!
