iOS 6 battery problems reported for iPhone 4 and 4S

As usual with any new iOS release the launch of the latest Apple mobile operating system, iOS 6, has met with a lot of praise but also criticism about certain issues, such as the now infamous Apple Maps app. We’ve been posting articles about the benefits and also some of the problems that have come to light with iOS 6 but now it seems there’s another concern. There are reports from some iPhone 4 and iPhone 4S owners that since they updated to iOS 6 their phones have suffered from excessive battery drainage.

Strangely this iOS 6 problem ties in with some of our recent posts as earlier today we told about battery tests on the iPhone 5 that looked pretty impressive although comments to our article from some readers showed they felt otherwise. In another post we told how readers using the iPhone 4 and 4S could downgrade to iOS 5.1.1 if they were unsatisfied with iOS 6 for any reason.

At that time we were unaware of any reported battery issues for iPhone 4 and 4S users but now we are hearing otherwise and there are suggestions that those using the above phones should maybe skip iOS 6, despite the many improvements it brings. BGR informs that there appear to be widespread complaints about the battery life for these devices since the iOS 6 update, with hundreds of people complaining on Apple’s discussion forums. Some users are saying that their device battery life is dropping by more than half after only a few hours on standby.

It has been suggested that part of the problem may be caused by location services such as the Passbook and Apple Maps app and so one solution could be to turn location services off although this doesn’t seem to work for all. Over on Mac Observer they are also discussing how many owners are seeing massive battery drainage on their iPhone 4 and 4S’s where this problem wasn’t an issue before they upgraded to iOS 6. The Mac Observer reporter tells how he hasn’t even run the Maps app so that doesn’t appear to be the problem in his case. However he has noted his iPhone loses around 10% of charge every hour when it’s not even being used, which certainly shouldn’t happen.

You can see the Apple discussion forums here with iPhone 4 and 4S owners noticing vast differences in battery life since they downloaded iOS 6. The MacRumors forum here also contains details about this complaint from iPhone users. We recall exactly this same problem happening last year for iPhone 4 users on the arrival of iOS 5. Personally I’ve noticed a slight drop in battery life on my iPhone 4S but nothing too major. Of course it’s difficult for us to know just how widespread this problem is though and that’s where you, the readers, come in.

We’d really like to hear your experiences of battery life on your iPhone 4 or 4S since the iOS 6 upgrade. Have you noticed a significant amount more battery drainage on your device? Maybe you’ve noticed a slight difference but nothing too drastic, or perhaps you’ve spotted no change at all? Let us have your comments.

    Iinstalled iOS6 last Saturday on my i 4s and now my phone randomly shuts down and restarts. Battery life is draining slightly faster also but the random reboots may be causing this. Anybody else seeing this restarting issue on ios6?

      My iPhone 4 charge used to last all day but after iOS 6 I run out of juice mid day and have disabled many of the features that are supposed to be the trouble makers. Also moving apps to different screens crashed my iPhone 4 twice and this has never happened before. I use assistive touch because my phone button is touchy and if if is the last thing you touch, phone does not sleep so swipe to a different page or some other gesture and phone will sleep. Husband has 4s and is OK with iOS6 upgrade. I should have waited.

    Since I upgraded to IOS6 on my 4S my phone will go from 100% to completely dead in 4 hours with minimal use…that is to say the occational email or text but no internet use. Not close to acceptable. I now keep it charging in the car, in the office and overnight.

    Definite hit on battery after upgrading to iOS6. My battery is at 51% as I type, and typically I would be in the high 80’s at this time of day. I have even noticed that the phone feels much warmer (at the top).

    My 4S gets really really warm from even minimal use or just from being plugged in. Also, my battery life… just no. In just four hours, I was on empty. For some of that time, my phone was off because of my courses being in session. I really need Apple to fix this ASAP!

    All great with iOS 6 for my 2 iPhone 4s and everyone else I know who upgraded. Mine is actually quite a bit better than 5.0, 5.0.1, 5.1, and 5.1.1 was. That device will be a year old in November. Brand new 4s was upgraded on day of purchase and it seems fine as well. No complaints with iOS 6 and to me its the best iOS yet.

    I am a proud owner of the iPhone 4s, but ever since I bought this handset, it stays in my room daily because of the battery problems, on full charge I can only use my phone for less than five hours, then another charging is required.
    I was also thinking abt downloading iOS 6, but couldn’t.

    I bought my iPhone early this year in April, and yet I can’t enjoy it on the outside world due to battery drainage.

    My iPhone 4S barely makes it 6 hours while being on standby since I upgraded to IOS6. I have gone to Apple and they say it isn’t the OS and that y battery is fine. I have tried restoring and nothing. I am really looking for a real solution because the only option I am given is to buy another 4S for $199. Then what, have the same problem?

      if you are using exchange email try and remove your email account, reboot the device, then add it back. Known issue with exchange email in previous versions after upgrading from 1 version to another. Also reset all settings, setup as new when prompted (that wont delete your apps or data). Reset wall papers and particular settings you had.Then drain battery all the way until it shuts down. Charge it back til 1.5 to 2 hrs past 100% undisturbed.

    I experienced battery loss of 10% an hour after upgrading to IOS 6. The Apple Care rep walked me through resetting my ‘Settings’, and now my battery looses only 3% an hour. Before IOS 6 I lost only 1% an hour, for comparison. It frustrates me that I had to spend hours re-establishing all my ‘Settings’. You would think Apple could have a better solution. Also, the company should have a better test plan to ensure that a new software release is backward compatible.

    Every since I’ve updated, my ringers and alerts have no sound and I have no volume control at all!!!

  21. The battery life on my 4S is has decreased significantly. If I’m using the phone to take a few pictures and do some Twitter updates I’ll go down to 50% battery life in about 3 hours when starting from a full charge. Something that never used to happen to me before and I’ve always been an avid social media user from my iPhone. When on standby it’ll decrease about 10% an hour for me as well. I’ve tried disabling bluetooth, shutting off wifi and closing all my open apps and still nothing. I haven’t seen Apple address this issue and I feel that at this point they should.

    After reading through many pages of Apple discussion about this problem going back several years, I happened upon a simple fix that does not seem to relate to the battery draing I was experiencing on my ios5 and ios6 iPhone 4’s. Go to settings open “general”, turn “restrictions” on and then off. Seems to have worked for both phones. Does anyone know why?

        After reading Apple discussion entries, I found the problem and a temporary fix until Apple sends out something permanent. Go to settings, general, diagnostics & usage, diagnostic and usage data. If you scroll down and find many, many entries that say “webbookmarks”, there’s a glitch when you leave Safari running in the background. After using Safari, be sure to close it by double clicking the home button and holding your finger on the Safari icon long enough to get a minus sign, then hit the minus sign to close the program. This has worked for me.

    The battery drain on my 4S is a serious issue following upgrade to iOS 6. A fully charged battery is fully depleted by lunch-time, even with no usage. I have turned off Siri and all location services (both rumoured to be potential causes) and don’t have any apps running in the multi-task bar. I have done multiple power-downs and resets and last night did a full restore. Nothing has made a difference.

    My iphone 4 has gone from 100% to 60% in less than three hours. I listen to music on the half hour journey to work, and sometimes look at a news app, but normally that would only drain maybe 15 or 20% of battery.
    With the various other issues the new iphone has, like build quality and maps, I’m starting to lose confidence in the iphone brand.

    Today I have experienced that my phone went dead, wake up button and power button didn’t work. This could be due to my recent use of mobile internet access and using maps a bit more than usual to track my progress to my destination. On arrival at home, I connected to charger on wall outlet but that did not work. I connected it to USB on my Imac and it did turn on after a few minutes and showing that there is still 80% battery power left. This is the first time it happened to my iphone 4 since I got it and I have updated it last week to iOS 6.

    My iPhone 4 was fine with battery life running iOS 5.1.1 After upgrading to iOS 6 I see battery life draining by the hour in stand by mode. The maps suck and the embedded YouTube is gone. If I knew iOS 6 was a permanent upgrade, I never would have installed it. It appears you could have downgraded from 6 to another iOS if you had beta 6 installed OR if you saved your SHSH blobs.

    I have the iphone 4s. I am a new apple customer, and I was prompted to update to iOS 6 immediately upon activation. In the beginning, It drove me crazy that the phone would loose 1% power every three minutes during normal use. I became so frustrated that I went online, and I performed a search for “iphone 4s battery drain” the results were immediately insightful. I have seen no argument that the new iOS, in conjuction with the 4 series phones, does not cause this battery drain (drain) problem.

    The new operating system causes rapid drain. I have followed all applicable steps to limit the drain, such as disabling wi-fi, location services, and any app that auto syncs/pushes/updates. Additionally, I changed the screen brightness to around 15% of max. These steps have allowed me to slow the drain down to 1% every 10 minutes +/- 2-3 minutes during normal use. This is unacceptable for a product that is supposed to be so revolutionary. I have now resorted to putting my phone in airplane mode while not in use as this appears to limit the drain greatly (less than 1% an hour).

    I have spent a great deal of time online trying to resolve this issue. I love the phone, but it is time for a solution. If iOS 5 worked fine with the 4-series phones then the first step would be to check the updated (iOS 6) objective-c code for any errors/memory leaks that may be occurring in the newly added functions. If apple has begun the debugging process, then the deadline for resolution has to be pushed up, and more programmers have to be added to the debug-project.

    If management makes this a true priority, even going so far as to offer monetary incentives for proof of resolution, creating teams that can perform competitively against one another for greater reward, and allowing some form of over-time incentive as well; this problem will be resolved rapidly.

    Steve Jobs is not there any longer, but someone else has to know how to lead. Someone knew of this problem pre-release. Whoever gave the green-light, does not value quality. That cannot go unremarked.

    All that is needed for mediocrity to triumph is for good men, and women, to standby and do nothing,

Sometimes, I could use it the second day. There are lots of complaints here but no real anwers. Come on, Apple.

    Battery drained from around 60% to zero overnight (about 7 hours) whilst on standby. I’m also unable to turn the phone off. If i swipe to turn it off, it just restarts again.

    iPhone 4S user here and I noticed my battery drain drastically since iOS6 after a whole day normal usage for me before the update I would be between 50 and 60 % but now immediately after the update I end up with 10 and 20%…. I ordered a new battery I will post back if it improves…

    Wish i’d read your review before I ran the IOS6 update on my iPhone 4. Since then battery life has deteriorated massively, to the point that it isn’t really mobile! This needs to be fixed ASAP!!

    Exactly as you noted – once I installed iOS6, my battery will drain after a few hours on standby. I’ve turned off location based services but that doesn’t help. Very frustrating!

    Overnight, my iPhone 4 battery went from lasting me a day and a half, to only 4 or 5 hours. I also jumped from never going above 700MB in monthly data to 3GB. No change in usage on my part, just the upgrade to iOS 6. I called apple support, and they clearly had an easy fix – but they wanted to charge me $20 for their phone support to fix it. I don’t feel like paying them to fix what they broke. #Fail

      Do you have a setting enable like GPS / Location services that may be set to ‘on’ after the update, where as previously you may have disabled such services / options?

    I’m experiencing the same problems as well. Since updating my Iphone 4 to the ios6 formate, my battery life as been dropping faster than usually. in the past i can go about a day and a half or more without recharging but now its every night i am forced to recharge it. Is Apple working on the ios6.1 and when will it come out.

    Hello all. Same for me. I have a high decrease of my battery life. It was quite funny to read this 10% per hour because I am not far from Those values. Although I do listen to some music in the morning for 45 min, I go from 100% to around 60-70. Of course I let you imagine what it is when I play games, videos or just browsing the web. A lot of helpers suggests to turn off some services like GPS and others things. Although this can be use for troubleshooting , it can t be used for permanent solution. Those phones may be very good but the price is extremely high, and it becomes worse when you read you need to turn off some services you payed for just in order to be able to use the phone normally. Not only this is incapacitating to have such a battery life, you may also consider the real impact on the battery life in the long run, until they make an update that may solve the problem. But it might be too late. Until then the battery will physically and irremediably suffer of permanent damage and people will just see no improvement. We are now feeling that Steve jobs is no more. Never he would let such a system come out.

    I have the same issue of very short battery life after upgrading to ios6 and was ridiculed by an Apple developer for commenting about this. Apple cut its teeth on the “it just works” selling mantra to justify the relatively high cost related to other products. If Apple can’t get its act together, its lead in the tech field is in jeoparday.

    my battery life on my 4s went from very good to very poor after upgrade the iOS6. If there any fixes besides the restore I would like to hear them. My wife has the same phone and did some of the location services fixes. I have done the same. Her’s battery life did get better, but even after trying to mirror the two phones I still have the same issue with battery life.

    Horrible battery life. I could go 3 days without charging my battery, now Im lucky if I get through the day and thats with hardly using it. My coverage was always awesome but now my phone is always saying “No service” or hardly ever has coverage. My iMessages wont go through as iMessages, only as txt msgs. Its crazy how loyal apple customers are and how much money we spend for these products and then we are expected to “downgrade” back down to iOS 5. Pathetic. Maybe if they didn’t worry about bringing out a new phone every other day and focused on the current products and prefecting those, we wouldnt have this problem. Now the rest of us have to suffer because we can’t buy the new one cause of lack of inventory, waiting and cost.. and for what? So the earplug jack is at the bottom (where it should have been to begin with) and for an extra row of apps and some extra speed. Give me a break. #unhappyloyalapplecustomer #timeforasamsung?

    Yes, I have the iPhone 4. I had this exact problem. I read about this on another sight. Go to Settings–>General–>About–>Diagnostics & Usage–>Diagnostics & Usage Data. Do you see a butt load of error messages dating from the install of iOS 6? Delete all of your bookmarks from Safari. It really manages the battery fairly well after this fix is completed. It is annoying that Apple didn’t see this problem in testing. I’m not an Apple fan boy, but the iPhone is the best phone I have ever owned. I read where they have seen other issues like this on Mac Books in the past. It has to do with the iCloud service. It gets stuck in a loop.

    Awful battery life… Till today it drained like 10% per hour which was more or less acceptable, but this morning it dropped around 30% in 1 hour being used for max 5 minutes. So, 55 minutes on standby, 30% off… Far away from acceptable.

    I am experiencing problems on my iPhone 4S almost immediately after I upgraded to the iOS 6 system. I am experiencing my apps closing unexpectedly, the physical phone is getting very hot, and my battery will not last more than 6 hours. I have already tried everything I can possibly do on my end with no positive results, it actually made it worse. Also, whenever I hold phone conversations the phone will cut out for 3-5 seconds where I will be unable to hear or talk to the person in the call.

    Massive change in battery life on my 4S and seems to be getting progressively worse. Overnight power drop when phone is not being used seems to indicate problem is in the background and unrelated to which apps are in use. Last night the phone had 45% available when I closed apps and went to sleep. 8 hours later it was at 1% and ready to die.

    the IOS6.0 update has drastically affected the battery life on my 4S. I have completed all the suggestions of turning off the location services and making sure all apps were “turned off” when not in use and these made no real improvement. I’m thinking I want to downgrade to be able to have my phone all day without having to charge it. I went from normal use of and 8 hour day and having plenty left to having less than 4 hours after an all night charge.

  96. yeah, my iphone 4s now has horrible battery life since I “upgraded” to iOS6…. today, I drained it TWICE. In one day! And I worked 8 hours so I wasn’t on it much during the day…

    I have also noticed a big drop in battery life on my 4S. I charge it every night and start the day off with 100%. before the iOS upgrade I would have approx 60-70% battery life left. I have not changed how much I use my phone at all but now I am having to plug it in after I get home from work. I am usually around 20-30% at the end of the work day. That sucks!

  99. I bought my Iphone 4s 3 months ago. Since the IOS6 My battery life has been the same, but sometimes when I get texts my phone will show the “Apple” Logo like it just restarted. Has anyone else experienced this?

    The battery life on my 4 has decreased a lot. For example, had it fully charged last night before bed, closed all apps, and woke up to 80% battery. I talked on the phone twice today, for a total of maybe 5 minutes, sent sent one text and at 1pm it’s at 59%. It’s very annoying for those of us that don’t have home phones and rely on our iPhone for everything.

  101. I just did the update on sat (it is now tuesday) and since then i am running out of battery by 8pm every day. Prior to the update i would end the day with half or more of my battery. It is extremely annoying and i havent even been using my phone that much.

    The battery life on my iPhone 4 has decreased ridiculously to the point where it’s 100% charged at 8am, down to 42% by 10:30am and dead by midday – this is where 98% of the use during this period was standby. I had a similar problem after one of the IO5 upgrades but NOTHING like as bad as this – and resetting my phone didn’t work this time either. Honestly, what on earth?!

    The battery life on my iPhone 4S has drastically reduced. After an overnight charge, the battery is dead by 12 pm or 1 pm, so it lasts 5-6 hours before having to be recharged. Bought it last April and problem started about 2 months ago.

    My phone was fine until very recently. The battery is draining so fast that during the 1 hour drive from the office to home, I see a 50% reduction. Overnight it drains to zero. I have read the comments on the net. If I knew about this issue, I would have never purchased this phone. This is a major problem. I am going to replace it with another vendor.

    Had no issue on my iPhone 4S on updating to iOS6, until the 6.1 upgrade… Battery has fallen 20% in an hour, when previously if phone not used, would hold a charge of at least 90% all day. Guess I was luckier than most not to experience the excessive drain until now…
