Battery is draining twice in a day on iPhone 4S post iOS 7.1 upgrade

I'm having a similar issue with my 4s. I did the update yesterday, restoring as a new phone. That afternoon, immediately after finishing the update, the battery was draining at about 1% a minute, with the only usage being listening to an audio book through my bluetooth headset for about 15 minutes, and simply carrying it in my purse for about 30 minutes.
I tweaked all the usual battery maximizing settings, charged it back to 100% and it was behaving normally the rest of the evening. I did not charge overnight, and it was at 47% this morning -- typical for when I forget to put on airplane mode and it spends the night searching in vain for a cell signal.
While driving to an appointment I charged it on my car charger. It got to 97%. While waiting at my appointment for ~ an hour I listened to an audiobook through the headseat and played a couple of games. Battery got down to 5% in that time, and the phone was hot. Not excessively so, I don't think, but definitely way above normal.
Given that I installed the 7.1 update by restoring as a new phone from the get-go, would your recommend I do it over, or try something else?
Thanks.

All day calendar events not being displayed in the notification centre for iphone 5 post ios 7 upgrade. Please help. Is it a bug?

All day calendar events not being displayed in the notification centre for iphone 5 post ios 7 upgrade. Please help. Is it a bug?
With iOS 6, the all day events showed up in the notification centre but it lacks in the upgrade iOS 7.

Same problem here. Some people pointed out that all-day events do show up in their notification center, but that seems only to be the case for birthdays (and only as text like the weather). I've tried it myself on my iPhone and iPad and it did work for birthdays but not for any other all-day events. I already sent this to Apple as a product feedback as well, as should everyone of you. The more people mention it, the faster Apple's going to fix this issue. In its current state, notification center is not a very helpful feature in my opinion. There's absolutely no point in not showing all-day events in the 'today' calendar overview.
Here's a link to the product feedback page: http://www.apple.com/feedback/
I posted my message in the iPhone section since I couldn't find a page specifically dedicated to iOS 7.
I really love the look & feel of iOS 7 but it's kinda sad to see notification center not tapping its full potential.
Cheers!

Over heating and battery drain on iPhone 4 after iOS 7.1 update

I am facing heavy battery drain and overheating after updating my iPhone 4 to IOS 7.1
The battery discharges @ 1% for every minute - when not in use / idle. The handset stays uncomfortably warm. The background app refresh, location services, screen brightness etc have been switched off/kept to the minimum. Though there is significant improvement in responsiveness. There were no battery/overheating issues with iOS 7.0.6.
Have reset all settings, switched on/off, given a hard boot (power button + home button) but no use.
Suggestions to resolve this are welcome.

This is not a software issue!!!. Yes, it may cause by the software update.. I had the same issue with my Iphone5 after 7.1.. I went crazy .. seeing my battery draining 1% a minute without using it.. and it took more than 7 hours to charge completely. Worst my IPhone was out of warranty cant take it back to Apple to have it fixed.
Things already did -
I changed the battery
Restored the phone
Switched to setting basically nothing
Waited for 7.1.1 to come out and then update the phone
But none of these helped at all
So i rolled the last dice.. took my phone to a local technician (in Philippines). They said none of the above will resolve the issue.
What exactly went wrong was the - USB POWER MANAGEMENT CONTROLLER IC U2 was busted. Once this was replaced my phone worked just fine. in fact I was amazed with the results.
My phone charged 100% from 20% in less than 60 minutes.
Now my battery lasts for more than 15 hours ( i do not use mobile data only Wi-Fi)
So if your phone is out of warranty no harm in getting this part replaced. If within warranty you may get a replacement handset.
Now to what causes this as per the technician " Every update from apple tries to exclude accessories that are not certified, and you do get the pop up that this accessory may not be supported" continue to use the charger will fry the IC U2 .
Hope this Helps goodluck

How to stop the battery from draining

I tried everything to stop my battery from draining on my iPad 2 since I have downloaded IOS 7.... Without success. Very disappointed with IOS 7 so far. Apple please release a patch to stop the battery from draining. It is urgent. My iPad is now useless, it is always drained to 0% everytime I open my iPad!?!?!

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Then see if placing the iPod in airplane mode when in standby helps.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:

I bought an iphone 5 2 days ago and both days, the battery has drained to 20% in 12 hours.... I thought it was supposed to have 8 hours of talk time? I haven't even been talking on it. 2 calls... just texting. Is there a app killer app available?

I bought an iphone 5 only 2 days ago and both days the battery has drained to 20%. All I have done is text and make 1 call... Are there any app killers or task killers for this phone to download?

Well, i bought two iphone 5 for me and my wife...she used it for only 2 days and she gave it back to me complaining from the same problem and she went back to her 4S, i thought she was kidding until i used mine,,,oh my god, the battery does not last for more than 6 or 7 hours, even without making any calls. i was so happy with my previous 4S as i used to charge it at night and stay almost 2 days on a stand by before recharge it again. well, im done with apple, have an appointment today in apple store to return mine, and even if they give me 2 new ones, i will not even open them,,,, for sale right away.

Ref:iphone 3G.I was visiting the US last week.One day my iphone battery completely drained overnight.I re-charged it but ever since it has either come up with a message saying it's registering, or that I need to register it.It was registered years ago.

Ref: iphone 3G. I was visiting the US last week. My iphone battery completely drained overnight. I re-charged it but ever since it has either come up with a message saying it's registering or saying I need to register it. I'm concerned that if I re-register it on itunes I'll lose all my data. I originally registered it a couple of years or so back, when it was new. Any advice much appreciated.

Thank you for quick reply. The data is still there - every so often when I switch it on, it comes up with the main icon screen, rather than the emegency calls only screen (which it does most of the time), and I can get to my contacts, photos, and so on, but it won't connect to any mobile/cell network provider, including my network here in the UK - O2.

My iphone 3G is draining off battery very fast.Wi Fi and other appliations are swithed off.Phone getting really warm just like that.Battery drains off in half day or less even in stand by mode.

My iphone 3GS battery is draining off in 4 to 5 hours even in stand by condition.
Tried with all the applications and Wi Fi off.
Phone is getting warm just like that!!
It was working fine in the last week!!
Any solution?
Varghese paul

There is no reason that a brand new phone should be having problems. I would say return it for a new one because it's less then a week old or return it. It's unacceptable. I have been having software issues with my iPhone 3GS too. I feel that Apple did a half done job on the software and really failed to bring new features to their third gen. iPhone.

Iphone 4 battery sometimes drains fast -- problem with Mail app?

My iphone 4 battery often drains too quickly, and I wonder if it has something to do with my Mail App.
When my phone is not playing nice, it drains at least 20% overnight while on Standby, and from 100% to 30% in around 6 hours when I use it during the day. I found a fix (http://discussions.apple.com/message.jspa?messageID=11775150) that basically says to wipe your mail account and set it up again.
This fix works, but only temporarily for me. I find that I have to keep resetting my mail every few days to get back to "normal battery" where it barely drains overnight. I only use one email account (gmail) -- could there be something going on there?
Oh, and when my battery drains fast, nothing changes when I turn off WiFi, notifications, push, etc. I usually have my mail refresh hourly.
Has anyone had this experience?

IPhone 4 battery still draining fast after ios 5.0.1 update

5.0.1 update did not help, my battery still drains just as fast as it did on 5.0. My phone used to last 2 days no problem, now it lasts about 6 hours, I could go to bed at 5% and wake up with 3%, now if I got to bed with 25% it's dead by morning. I have all iCloud services turned off, only Maps turned on for location services, notifications for Phone, Messages, Reminders, Calendar, CNBC RT and Words Free. I have 2 email accounts, one is a pop3 and the other Exchange, both are set to pull every hour and preview is turned off. Is the issue with notifications? the only thing that has changed from 4 to 5 is I have notifications turned on and my reminders & tasks are synced with Exchange. I'm starting to think the issue is with notifications, I tried to turn off email notifications for the lock screen but they still show up.
Are we getting another update after 5.0.1 soon for the continued battery drain issue?
Email notifications continue to display for locked screen even though the option says Off, is there something else I'm missing?

ITunes Match causing battery drain and high CPU load on iPhone 5(S)?

Hi.
I'm wondering if anyone else is seeing this — coz i see no such reports anywhere:
On my iPhone 5S, ever since iOS 7.0 (and continuing with 7.1), downloading songs form iTunes Match, downloading any album from Match is really slow, heats hop the CPU and drains the battery. (As ar as recall, all was fine under iOS 6).
Here’s steps:
i go to the Music app, tap “download all” for an album, or maybe a whole artist. The Downloading/Pending icons appear. Because status reporting is vague, i switch over to the iTunes Store app and its Downloads tab, which provides more info.
Here i see the first three songs downloading fairly quickly (i have fast WiFi), but once the progress bar reached 70%-ish, they go into Processing, and stay there for anywhere between 3 to 10 minutes. Eventually, they drop form the list (i.e. are done) and the spiel repeats with the next set.
While this is happening, my iPhone goes incredibly (“uncomfortable to hold” hot), and i can literally see the battery go down.
My iTunes library is largish, but not huge. i have about 17k songs, most of them iTunes purchased. (since Match has a limit of 25k *plus* iTunes-purchased songs, i’d expect 17k to be child’s play). On my phone, i have very few to no songs at all.
The other day, i completely reset my phone, didn’t restore form backup, and set it up fresh with only handful of essential apps. I’ve been seeing incredible battery life — i was still on 30% after over three days, yesterday. I then decided to try Match again — fresh, for the first time since the reset. I triggered the download of *one* album. The battery went down 8 percentage points while that album was downloading, and again the phone heated up immensely. Once the download was done, the drainage slowed down, but still seemed excessive compared to before (i was at 16% within an hour or so). I then shut down and rebooted the phone — and batter life was back to be excellent — the remaining 16% got the phone over the night.
Ok, so the first instinct is, of course: something if screwed up with my iTunes Match library, cloud side. right? So i grabbed my girlfriend’s iPhone 5 (also iOS 7.1; *much* smaller and completely separate iTunes Match Library). Triggered the download of an album and — lo and behold — the same behavior: songs hang in Processing for long (maybe not quite as along as for mine, but it’s i didn’t measure), and 3% battery drop for downloading 10 songs, and the battery continuing to drop faster than usual, after.
So of a sampling size of two, both libraries and (totally unrelated) Apple ID accounts show the same or similar problem. Yet no-one else seems to be reporting this, or similar, problems with Match? What am i missing?
I should also add that i see no such issues on my iPad (also running iOS 7.1 now), nor on my MacBook Air (my main Mac has the full iTunes library on disk locally). Downloading songs there works fine and prompt. I also have no problems *streaming* songs form Match.
*Does* anyone else see this? Any suggestions what to do to address this?
I’ve also filed a bug report with apple as radar://15964682.
thanx!
marc

I am experiencing the same issue as dwarfland. I have a black 64GB iPhone 5s running iOS version 7.1.1 and a grandfathered unlimited data plan with AT&T. I have had an iTunes Match subscription pretty much since it was introduced. I currently have around 19500 songs in my music library and try to have only around 2000-2500 songs physically located on the phone itself (all of my "top-rated" songs in a single playlist). I have recently needed to re-download all these "top-rated" songs after I restored my phone from a backup, wiping all the songs from my phone. Thanks for posting your experiences, hopefully someone from Apple will notice and help us out with a solution.

Iphone 5 and IOS 6.0.2 is draining my battery! (new thread)

Well, apparently Apple doesn't want us to talk about this -- They locked the previous forum I had created after 217 posts and 16k views?
I'll assume there is some other Apple Forums rule that I don't know about that would cause them to do that instead of trying to stifle the reporting of this problem? It was clearly generating many posts that show a correlation between IOS6.0.2 and battery issues.
To summarize... I was having significant WiFi issues on all my apple products (several Iphone 4's and and Ipad2) with 6.0.1 - all the same issues that have been reported on these forums thousands of times. I was excited to see 6.0.2, hoping it would correct the wifi issues for my iPhone5, at least. Unfortunately, not only did it NOT correct my wifi issues, but now my battery is draining about 5x compared to before. I can barely get through a day of batterly life with minimal usage whereas before 6.0.2 I was easily able to go 2+ days.
An apple representative called me today (actually he tried very hard to call me for several days.) I was appreciative of the reachout (saw my other post) and was hopeful they would be willing to help me. The guys was very nice, but it truly felt like he was reading a script and was more interested in getting information from me. The only advice he ad for me was to back up my phone and then reset it to factory settings (like new) without using any of my previous apps, mail, etc. He wanted me to do this "for a day or two" to test it and see if the problem persists. Then, if the problem is gone, we can work together to restore apps/settings one-by-one until we find why the problem is there. In other words, they have no idea what is causing this problem, and they want to use my time to help them figure it out.
Ironically, I was able to watch my battery indicator drop several percentage points while I was on the phone with him for about 20 minutes.
When he asked if I would do the restore and/or load profile software on my iphone to track my usage, I said no. I shared with him I'm simply out of time and energy -- I have logged over 40 hours trying to debug these wifi issues (I'm somewhat tech savvy and figured I could just plow my way through to a solution with my router/security settings.) When I realized that these issues are all IOS driven, and now the battery issues, I find I've had enough.
Maybe I'll go return this Iphone5 and ask for a replacement. However, I'm also seeing other posts saying that did not solve their problems.
We are talking about wifi and battery life. This is not new technology.
If IOS 6.1 doesn't correct these issues, it's probably time to buy an Android.
Please keep posting things directly relevant to BATTERY issues with iPhone5 so that this thread can stay on task and bring to light the correlation between 6.0.2 and the battery. Maybe Apple will care about their loyal customers, acknowledge the issue, and let us know how much longer we should wait for 6.1 to fix the issue before it's too late and they start losing their fan base. No information from Apple is only exasperating the problem.

I had the same experience with a new iPhone 5 that I bought last week. Did not have a chance to measure battery life before the 6.0.2 upgrade installed but I set up my phone exactly like my 4S and immediately started running out of power after short periods. Went to Xmas get together with fully charged 5 and 4S. Heading home the iPhone 5 shut down for low battery and the 4S had 65% power. Both phones had two half phone calls on then and no data usage.
That night I fully charged the iPhone 5 and, without lighting it up, put it on my night table. Next morning I picked it up and looked at battery indicator and I had 42% charge with NO activity!
Tried it again next night and wound up with 37% charge. (Slept longer).
Today I called the carrier and reactivated the 4S. Took the 5 to Apple Store and they kindly gave me choice of new replacement phone or refund. I took the refund. Uniquely, the Apple Store said it was Verizon CDMA phones that were coming back.
The are other strings on this with temporary solutions, but from my experience with 7 firmware changes on an HTC 4G phone the problem will continue because the solution will be hardware caused. We are in the days where RTM means Rush to Market - not Release To Manufacturing.
I fear the only solution is to either wait for the next model (I did not notice a really major change in performance over the 4S in LTE heavy Seattle area) - or switch to another manufacturer.
It might be useful for these forums to indicate if you have a GSM or CDMA phone to see which have more problems.
Discouraged....

New battery still drains while not in use

A few months ago I noticed a battery performance issue on my 1 gen nano (quickly discharged, drained while not in use). I bought it the day they were available in stores (which was in 2005) so assumed I just needed to replace the battery. I installed a new battery and fully charged it with the ac adapter. However, I'm still having the same problem. After some troubleshooting, I found that it played for 5 hours on a continuous loop with no EQ and backscreen light off. The battery was fully drained. I again recharged in with the ac adapter to make sure the battery meter was recalibrated. After it was fully charged again I placed it on my desk and didn't use it. However after another 5 hours or so it was drained again. This is my second purchased battery so I doubt it's the battery. I have restored the nano numerous times. Any thoughts as why a new battery would drain while not in use? Could this be a hardware issue? Thanks in advance!!

You either have an alarm set in clock or calendar which is causing it to play while you think it is off or you have a logic board short. I'd bet on the latter. You can have it diagnosed at http://www.iresq.com for $9 or Google for other 3rd party repair sites.

BB Tour 9630 battery keeps draining

Hi:
I'm having a problem with my Tour 9630 battery draining. When it first started was shortly after installing an animated theme, which I deleted later. That solved the draining problem for about 2 days and then the battery started draining again. I have deleted a number of apps that I thought might have been the culprits but the problem is still on going. The battery will drain even if I power off the phone. I took the phone and battery to the Verizon store where I purchased the Tour where they checked the phone and battery and said everything looked ok, they recommended doing a battery pull and see what happens. I pulled the battery and that stops the draining until I use the phone and then the draining starts again. As it is now at night I power off the phone and put it on the charger but it usually will drain when I have the phone holstered during the day. Does anybody have any ideas what might be happening and how I might fix this problem?
Thanks; Jon

Hello Jon,
In this particular case I would recommend performing a clean reload of the BlackBerry Smartphone software.
First step would be to create a back up of your BlackBerry. To do this please open BlackBerry Desktop Manager Software and connect your BlackBerry Smartphone. Then click on Back Up and Restore Icon and select Back up. Make sure to note the location of the back up as we will require to access it to restore data after the reload process is complete.
Once the BlackBerry Smartphone is backed up please follow the attached knowledge base article to reload the software on your BlackBerry Smartphone.
Link: http://www.blackberry.com/btsc/kb11320
Upon completing the reload of the software I would ask that you monitor the devices battery levels prior to doing a restore of the backed up data. If you synchronize the BlackBerry Smartphone you can resync to get your organizer data back on the device.
Thank you

This iPhone4s battery is draining the life out of ME! Help?

I just made the jump to my first smartphone because of the iPhone 4s. So many wonderful applications and functions. Mostly Siri. I'm so dissapointed. I have only had it 3 days. The battery drains so fast, I have to charge it 2x or 3x a day. My old LG octane (yeah.. I know) Could go days.. Im seriously thinking of returning this silly phone. I was so excited, and now, I feel like crying.
I have tried everything. System resets, drain battery, charge battery, deleted apps., deleted mail account, turned off Siri, push notifications, location services, time zone, I have turned off just about everything there is to turn off! It is STILL draining. And seriously?!? Whats the point of getting a smartphone that has all these wonderful things and all these cool functions.. only to have to turn them all off!!?? Its not very 'smart', if you ask me!
Signed,
Dissapointed and totally frustrated!!!

Thank you for replying to my Whiny post. LOL Here is a list of everything I did!
This was a new phone start up. I didnt back up from iCloud.
I tried turning various things on and off to solve it with no luck.
Finally, last resort. I did these 5 things last night before bed.
1. Deleted my email account.
2. Went to settings -> General -> Reset -> Reset Network Settings.
3. Completely switched phone off and restarted.
4. Drained the phone completely and then fully recharged it. When I got up this morning, it was the first time battery charged to 100%
But still have major issue: Battery has drained 13% with 1 hour usage/1 hour standby
I have Siri running
Re set-up my email account
Switch on location services and have only 3 items I want, switched on (Siri, maps, and weather)
Switched off Location-Based iAds, Setting Time Zone,
Push notifications set for (messages, phone, and reminders) everything else is off
Brightness screen is halfway
Raise to speak is off
Network cellular data off
restrictions off
bluetooth off
passcode lock off
Date and Time is off
Accessability off
Fetch new data is on, but set to manually
Photostream on
Store cellular data off
Called Apple this morning. The tech was very curtious and sympathetic. They are sending me a new phone. I am not very optimistic, but I will try and hope for the best! I really, really love this iPhone 4s, but I really, really hate this freaking battery issue!
