Apple Seeking Help From iPhone 4S Owners To Solve Battery Drain Problem


Not all but some iPhone 4S owners have been complaining about rapid battery drains both while in active use and in standby mode. Luckily though, I’ve not had such a problem with my handset. But now, it seems that the issue is actually quite serious as Apple engineers are reportedly contacting select iPhone 4S users to help them figure out the battery drain puzzle on the new device, according to The Guardian. The source also points out that Apple has quietly reduced the standby battery life from 300 hours on the iPhone 4 to 200 hours on the iPhone 4S in its data sheet.

One owner who was contacted by Apple told the Guardian:

“My battery life was extremely poor – 10% drop in standby every hour. I noticed that the usage figure was roughly half that of standby, even when the phone was not being used, so I assumed something was crashing or running in the background. I switched off all the new features including Siri and location services, but it was still really poor. I also tried setting up a clean phone with no apps but it is still really poor.

“I then got a call from a senior [Apple] engineer who said he had read my post and was ‘reaching out’ to users for data and admitted this was an issue (and that they aren’t close to finding a fix!) and asked lots of questions about my usage and then asked if he could install the file below and that he would call back the day after to retrieve the info. I extracted the file from my Mac after a sync and emailed it to him. He was incredibly helpful and apologetic in the typical Apple way!”

The battery drain issue has generated massive amounts of discussions on Apple’s support boards, with some people claiming that backing the phone’s contents up to their computer and then restoring it improves the life. Are you experiencing any similar issues with your iPhone 4S? Please do share with us in the comments section below.


  • Hasnt there been reports of extreme drain on the normal iPhone 4 with iOS5, as well?

  • Kusanagi

    I am having major problems with battery drain on my 64 GB iPhone 4S. My wife just upgraded her iPhone 4 to iOS 5 and she doesn’t seem to have any problems, so not sure about the other user’s post about it possibly being an iOS 5 issue.

  • sp

    total battery drain takes about 3/4 of the day for me. thats with very little on the phone calls. mostly text messaging, whatsapp and twitter here and there.

    hardly ever use Siri….

    any help with battery life would be greatly appreciated!!!

  • Wendy Knudson

    I’ve been noticing the same. I went to bed the other night with 20% charge and my phone was dead in the morning. A full charge diesn’t even seem to last a day, although I do admit it’s constantly in use.

    Actually just tracked down an issue on my iPhone 4, with iOS 5 that was causing a huge drain. It turned out to be the push settings for an exchange account I use. Once I set it for Manual mode for email retrieval my battery life is back to normal.

    Hope that helps.

    I have experienced this problem since the first day.
    I thought it was the restore from the back up I had from my last iPhone 4. Because I had the same problem with my iPhone 4 battery.
    Went to see a tech at the apple store here in Montreal and he told me to back up everything on iCloud, restore the phone to factory settings and then install all what I had from iCloud.
    We did this at the store but the battery problem is still there.
    E.g. : unplug my phone after a whole night charge at 9:00 am 100%. By 12:00 I’m at 55%. That’s without using the phone more than sending 10 SMS, location off, bluetooth off, I don’t have facebook or Skype because they tend to use FAA in the background.

    Only problem I’ve had other than some apps not updated to ios 5 compatibility, is the sound check is not working properly when listening to music.

  • Andrew B

    By FAA I meant data… iPhone auto correct

  • Daniel

    Considering I upgraded from a dying iPhone 3GS, I can’t tell if my 4S battery time is good or bad. All I know is that I’m happy I don’t have to charge my iPhone 3 to 4 times a day!

    I did, however, go into the location services and disable some of the system services.

  • At lease apple’s problems are smaller than when RIM released the Playbook and BBM and email didn’t work.

  • Wes M

    Not that I have seen: four of us have iPhone 4 and iOS 5 without the drain issue

  • Kenzie21

    I’m finding a definite battery drain..typical use and having no battery life at night..this sucks

  • Kenzie21

    Plus I just got the phone last week after trading up from an iPhone 3G

    same here. had the 4S for a week now it is as bad as my old 3GS. rarely talk on the phone. mostly texting and tweeting. a full charge doesn’t last 12 hours. glad to hear Apple is looking into it.

    Sound Check isn’t very good at what it is supposed to do.  Try iGain instead.  It uses ReplayGain, which actually accomplishes the intended goal properly.

  • Joel

    We are all apple fans here, but let’s admit it; the iPhone 4S battery sucks. It’s worse than the iPhone 4 which itself wasn’t good either.

    Before the iPhone era I had a Palm treo which had an excellent battery.

    Time for apple to reinvent the battery.

  • Jonathan

    I was getting like 30% after about 12 hours, then a couple of days ago i switched the settings in Location Services > System Services > Setting Time Zone and Turned it to off. Now it’s back to the same as when i had my iPhone 4, it’s been 10 hours and still at 85%

  • Outdoordiscoveries

    I’ve been experiencing this with my 3GS lately.  Sounds like the same issue…and is draining overnight.

  • Setak

    I don’t know what’s the issue, but for me I have around an average of  loosing 10-12% an hour on my iPhone 4S. I noticed that when I’m talking on the phone, the battery drains slower, probably because the screen light is not on. Maybe the light brightness has something to do? But still, it is annoying to charge it once or twice during the day.

  • Cell only

    Same here. My iPhone 4S battery is exactly the same as my 3GS I can barely get through half a day without the battery going almost to zero

  • Wuju

    I also experience battery drain with little usage. mostly texting here and there and hardly uses the phone. No Siri, location off. I hope Apple is fixing this and I truely believe if we have the option to turn of 3G, it may really help to reduce the battery drain. Wish there’s an option to turn it off and we will see if that is the major cause on the Iphone 4S drain.

  • Brian

    I think it might be an issue with iOS 5. My wife and I both have iPhone 4,mine seems to be fine(heavy user)while the wife’s battery drains rapidly and she doesn’t use her phone nearly as much.

  • Anonymous

    Anyone has Skype in the background? I remember when I had it on my 3GS the battery would go flat in no time. Just killed it on my 4S let’s see what happens over the next 2 days.

    Apple: we need FaceTime over 3G please!!!!

  • Jay

    I have two iPhone 4 phones and both are running very warm and battery draining very quickly.
    Have tried restores with no luck. Apple store says they havnt heard of any issues with battery drain. I hope they figure this out.

  • Anonymous

    I have the iphone 4 and when I switched to i0S5 things changed for my battery. It reduces so fast now – even if I am not on it. Just like some posts are saying reducing by up to 10% an hour. I have tried turning off Locations Services, Bluetooth and icloud but not notifications. That will be next if it doesn’t improve.

  • HeWhoRidesAPony

    you can turn off 3g, settings, general, network, cell data off. you will still be able to send receive msgs (with bell, not sure about other networks) but will be prompted to turn it on for just about anything else that needs a data connection. i usually turn mine off at night or if i am not using it at work.

  • Anonymous

    Shorty. Thank you. That worked freakin awesome. You are now my hero. Lol

  • VC

    I found that if i charge my 4s with laptop, the battery drains really fast, but if i charge it with power from the wall, it has no problem to standby for 3 days with regular usage. 
    Hope this help.

  • Anonymous

    I do have this problem to! But only when I’m on the 3G. I can leave the phone on the table and not use it and still loose almost 10% every hour when I’m on the 3G or  edge. But if i’m on the wifi the battery is fine. I also noticed the my network always switch between 3G and Edge with full signal…

  • Too bad about battery life hope it gets fixed soon.

  • Guest

    obviously with all the new features you have to turn what you aren’t using off. people are saying, maybe the brightness of the screen has something to do with it? OF COURSE it does, are you ridiculous? Turn it down to half, also turn off automatic light sensor, turn off spotlight search, turn off wifi and bluetooth, turn off location services for each app AS WELL as the whole thing entirely, if you’re not using it that is! MAke sure you force quit all apps after using them, also I always do a hard reset once every day after force quitting my apps in the morning. If you guys have backing up to iCloud turned on, turn it off as well as all the icloud options, turn off ringer, just use vibrate, tur off push new data under mail contacts, etc.turn off facetime, and of course theres more.
    If you don’t turn off all the features you don’t use what do you expect? And you don’t charge it with the wall charger but with the computer? Seriously, I charge mine with the wall jack every night when i go to bed wake up at 100%, i would say i heavily to moderately use the phone everyday. at night i’m still at 70-60% at least! anyway, hope this helps.

  • Well,I can’t imagine how the future will be like. Anyway, I just can’t be bothered with that, I’m just more concerned about my iPad 2.

  • Buddybuds89

    It’s not good to recharge a half full battery

  • Kim T

    I had the same problem. My 4S was in standby mode and went from 90% to 17%, shut itself down, in standby.  A soft reset brought the phone back, but there were no apps running and this is worrisome.

  • If it’s frequently used and you have so many programs running in it then it’s normal to experience battery drain. I guess, this also goes for other gadgets we have.

  • Dalagatta

    i can’t keep a battery more than 2 days without using my iphone. I have restored several times as indicated by th Apple store staff but nothing changes. Please help. The phone is not reliable.

  • Dkjmshw

    Yes I’m having same problem.very unhappy.what good is it if it goes dead in 4 hrs.i can’t have access to a charger when I’m it’s a big problem.i can’t believe we have a problem like this.i never needed to charge my 3G went dead & I didn’t even use 4 – 6 hours from a full 100 percent charge.very unhappy.What good is it if we have to turn everything off.

  • Mona

    I have th battery draining problem even after updating the latest software. I went to sleep wit 70% charge on my phone and my alarm didn’t woke me up coz the phone’s charge was drained. I’m disappointed … I always wanted an iPhone and now I don’t want it anymore.

  • Salas

    I am having the same issues. The battery doesn’t last a day’

  • june

    that seems kind of ridiculous, you might as well turn off your phone in total and turn it on whenever you need to use it.

  • Patty

    I just purchased an iPhone 4s last week. This battery drains like crazy , all the time time when I’m doing anything and did the boot prior to turning off. Simply won’t hOld a charge and Siri seems to work less half the time. Don’t know of there are issues w my
    Voice, although she has completed a few tasks I hav asked. Both battery and non responsive Siri are a disappointment and frustrating. Made a trip to att store yesterday and was told if it did
    Not operate up to par , to bring it in befor march expiration date re return. And they wd look at it again and then replace w new one.

  • Matrometer

    I got my 4s iphone about a month ago and all was fine until about a week ago.  Now my battery drains in standby about 40% overnight with no use at all.  I have turned off just about everything that would drain it.

  • nigam
