Iphone 4s ios 7 battery issues

did you change the settings at al ? How many hours are you using your phone per day ? That's realy imprssive if you have 80 % at the end of the day ..

Hi everyone,

i've been following this post because i had the same batterydrain with my iphone 4s under ios 7.

After trying every tip & trick i recently discovered what caused my batterydrain. I have a femtocell in my home (small 3G router to enhance my cellcoverage indoors). Since iOS 7 this combination causes my iPhone to drain rapidly. In iOS5 and 6 i haven't had any problems with it, but iOS 7 has triggered something. I've unplugged the femtocell and now the battery performs normal again.

My provider Vodafone has this under investigation.

I don't know if this helps anyone but i thought i'd mention it.

Guys, I recently found this thread. I had the impression that I was the only one with a joke of a 4S smartphone. I was very tired about battery draining from 100% to 75% in the first hour after unplugging the charger and 20-25% in 3-4 hours. Also, from 10-15% it was fully charged in 35-40 minutes.Two months ago I went to Vodafone and asked them to send it to local Apple service as it was still in warranty. Ten days after I received it back with a mention that the complaint is not confirmed. 🙂 In the last days of warranty I sent it back, this time also with a email explaining that I'm not buying any specialist opinion that after 700+ cycles, the battery is still in parameters. Finally, after Vodafone also wrote them, they changed the battery. The first thing I noticed was that it charges much slower. I also made the settings recommended by Dariusz777 (Thank You, Dariusz!) on page 12 of this thread and, guess what, after 100% charge last evening, I woke up with 100% in the morning and came home tonight with 50%.

So, my opinion is that regardless of IOS 7 features and settings, also the battery should be changed in order to get more usage time.

Good luck!

I'm having the same experience with my 4s. Haven't found a way to fix the battery problem but I've chosen a solution. My love for Apple products has been tested enough. I switched to mac products years ago because I was tired of the frustration with PC and it was worth the extra money for a while but I find now that I'm just as frustrated these days with Mac. Not to mention the higher price and proprietary connectors. It's not realy worth it any more. I'm moving to a Samsung.

This is not only infuriating but it's just unacceptable. I waited to upgrade to iOS 7 on my 4S until a few weeks ago as I have used Apple products for 30 years and I know better than to jump on anything new right out of the gate.

But boy-oh-boy did I make a mistake. My phone is now practically useless because of this insane battery drain. I used to get 2 days with only getting down to maybe 20% on iOS 6. I run a really clean phone anyway and even with turning off eveything it still just dives to shutdown in a matter of hours only on standby. I make sure nothing is running in the background and quit all open apps and such.

But even that aside and all the "tips" going around to turn a dozen major features off (which hasn't helped me anyway), the point is we shouldn't HAVE to essentially disable 90% of the features of our phones just because of a faulty programming issue!

I've never been so irritated with Apple in 30 years.

Well I'm afraid I had a moment of weakness over the Xmas period and upgraded to a 5s and I am very happy with the phone... So I won't be participating in this convo any longer, although I still feel Apple are def at fault for introducing an iOS that IS NOT FOR IPhone 4/4s.... Anyway see ya

My battery as well is awful ever since iOS 7, especially here on iOS 7.0.4. I've had my battery replaced TWICE now at the genius bar at the MacArthur Mall store in Norfolk, VA. I still have the same issue. They said they cant replace the phone due to them being serialized (however that matters). I charge it overnight and then at least twice a day just to get through it and this is on a brand new battery replaced by the genius bar. I have all the settings/services turned off or minimized for best performance. My friend Jon says it seems to be the phone itself...but there are no options from here.

Called it in to AT&T so they will provide documented feedback to Apple. That's the only way we'll get some action taken. I encourage people to do the same rather than just complaining about it online.

My tech gal said that she has a 4S and has never had a problem with the battery and in her experience talking to customers it does seem to be device-specific for some reason rather than all 4/4s phones. So then I hung up and filed an insurance claim to get a new one sent and we'll see what happens.

I recently updated my 4s to iOS7 and have experienced some of the terrible battery performance described here and elsewhere on the web. I tried a complete clean restore and added my own data and apps and then tweaked all the settings to maximise the battery life and found that the phone started behaving as well as it had with my previous iOS. (I'd upgraded from 5) This was roughly observed over a day, no scientific data logged i'm afraid. I then updated the 9 or so apps that had updates and my battery bar raced to zero again. I've been closing all apps while the phone is in standby, but maybe one or more of these upgrades is what is causing my problem, or at least most of it. Anyone still suffering similar problems this might be worth having a look at. I've restored the phone again to iOS 7 and added my data and apps, no upgrades for the apps, and the battery/phone seems to be so far so good.

After I upgraded my phone to iOS7 and also upgraded all my apps. My battery was draining by 25% every hour. I found out that one of my apps was constantly crashing, even though I cleared all running apps from the backgroud.All I had to do

My 4S had battery drain problem also. But by doing below, battery life is greatly improved:

Go to: Settings \ ICloud \ turn off or disable "Find My iPhone"

Okay, I've been having the rapid battery drain issue and followed all these recommendations along with one other suggestion from an Apple phone support guy. My 4S now holds a charge for up to 24 hours or more--even with light bluetooth use.

In addition to Dariusz777's awesome list of functions to turn off, I also learned that my install of iOS 7 was either corrupt or had a bug of sorts. To determine if your phone has this iOS issue, physically dock your iPhone with your Mac and check the mulit-colored status bar in iTune that shows storage allocation for photos, apps, music, etc. The yellow segmant is iOS7, and on my system iOS was using over 5Gig on my 32Gig 4S. I had noticed this was the largest allocation for iOS that I'd seen, but didn't make the connection. The Apple tech said it should be under 2Gig--approx. 1.7Gig.

I saved a backup to iCloud--only data, no firmware or iOS--then reset the phone to factory default, and ran setup as a new iPhone. I then restored my data from iCloud, and did a manual sync of music, apps, photos, ectc. The Apple tech said to avoid backing up from my iTunes backup. Apparently settting up as new, and pullin data form iCloud, allows the phone to pull a new install of iOS7, where as install from itunse backup risks replicating the iOS glitch.

On my first attempt, to "clean install" iOS7, it worked as the tech described, and my iOS install dropped to ~1.7Gig and the battery life showed good improvement, but within a week it had bloated to over 5 Gig and the battery was again rapidly draining and shutting off.

This week I found and applied all of Dariusz777 suggestions, deleted a bunch of unsued apps, did a synch to iCloud, and and repeated the factory reset and new phone setup recommened by Apple support. The two process combinded resulted in a massive improvment in battery life (almost like new!) and my iOS7 install size remains below 2 Gigs. (iOS 7.0.4)

I've come to suspect there may be an issue within Wallpapers & Brightness because the Auto Brightness function never really seemed to work, and turning off Auto Brightness (along with Motion effects) seems to improve matters noticably.

Also, I nolonger have the "processor hot spot" on the back of my iPhone.

Thanks Dariusz777! I hope my additional insights on iOS7 "bloating" help other iPhone 4/4S owners. Clearly this is a nasty software bug in iOS7 and not a "conspiricy" on Apple's part. Apple support spent nealy an hour with me trouble shoot battery drain and my phone was 3 months out of its Apple Care+ coverage.

NOTE: I have two ATT, iPhone 4S (white and black) both purchased at the same time, both upgrade to iOS 7 with all latest patches. One (white) developed the battery drain and bloated iOS problem and the other did not. As I recall, I had a download/intallation glitch with my iOS7 day-one install. With the black phone, I waited a few days and had no download/install glitches.

I bought a new iPhone 4s in January 2014 and soon discovered that it had excessive battery drainage. It dissipated from 100% to 0% in 12 hours of standby time. I consulted these forums and learned that this is a common problem. I tried re-loading IOS, removing all other applications, deleting my iCloud account, changing settings to their most-power-miserly options - but nothing worked. After fully recharging and waiting an hour of standby time, the displayed usage and standby times would be about the same. Finally I took my iPhone into my local Apple store and they exchanged it for a new one. The difference is like night and day. With the replacement, I can have all of the settings at their most power-hungry option and my battery dissipation only drops for 100% to 90% in a day of typical usage. The display now shows my usage time as only a small fraction of my standby time. I am now convinced that some iPhone 4s devices (even brand new from the factory) have inherent hardware/firmware faults that no amount of tweaking of the settings can fix.

Hi Fi Fan has it right.

Turning OFF Find My Phone helped a lot.

Thanks

Hey guys i have found the solution to my problem. In the beginning battery drain was enormous. Within 6 hours battery was gone in stand by mode. I set up the iphone as new and it was ok. The problem started when I installed viber (even when it was not running in background). I don't know why but when I unistalled it everything is back to normal and maybe even better than before. Maybe in your cases is another app that causes the problem. So start with a new set up and putting your apps one by one you maybe find the solution.

I hope this helps..
