Battery Drain Fix iOS 5.0.2 Being Replaced With iOS 5.1

It seems that the battery drain problems impacting the iPhone 4S were expected to be corrected in iOS 5.0.2, but it is starting to look like the 5.0.2 version is not going to see the light of day. Last week, I had reported on the rumored delay of iOS 5.0.2 and that now appears to be the case. Apple is already releasing to developers iOS version 5.1 which is reportedly going to fix the battery drain issues which has turned into BatteryGatefor Apple.

It makes one wonder why Apple has abandon iOS 5.0.2 as we have not heard anything in the past week, but have been hearing a lot about iOS 5.1. With recent reports that it may not completely fix the battery drain issue, it makes one wonder where Apple is on resolving this ongoing problem. This may be another of those incremental fixes that they will be doing where iOS 5.0.1 appeared to fix some of the iPhones which were having battery life problems. Unfortunately, the “fix” created the battery drain problem in iPhones which previously were not experiencing any problems with battery life.

The problems persist and it seems that they are increasing as more people wonder what has happened to the battery life on the iPhone. Does Apple want to see this BatteryGate issue grow into a major problem for them? Obviously not, but the silence on what they are doing about it is troubling as the number of people complaining about the problem appears to be growing and includes more than just the iPhone 4S.

Since iOS 5.1 is now out in Beta to developers, it would appear that it will be released before the end of the year unless they find some problems with what it contains. There are expected enhancements in this version, but for many, the one thing that they are looking for is battery life. Anything less than that will mean a failure to those iPhone owners. The popularity of the iPhone does as much value for those owners who cannot go a full day without having to charge up their iPhone because of excessive battery drain. Without adequate battery life, they are forced to continually charge the phone during the day.

This problem is impacting far more than just the iPhone 4S and there are growing reports from people commenting on posts where iPhone 4 and iPhone 3GS owners are reporting problems from the iOS 5.0.1 fix for the battery drain problems. It seems that Apple has increased the number of impacted devices and there are probably far more people experiencing problems than those who are reporting the problem.

At the moment, it is not known as to when Apple is going to have a fix for all the iPhone owners who are impact by the Battery Drain issues they are experiencing. One can hope that additional changes are added to iOS 5.1 to improve battery life for all those iPhone owners who have been reporting problems. For the moment, it does look like iOS 5.0.2 has been abandoned.

    You know, a funny thing that happened to me recently was I went ahead and restored as new to iOS 5.0.1 from Firmware 4.3.2 and I was getting horrible battery life. Unfortunately I didn’t have an SHSH Blob for 4.3.2 so I had to go ahead and downgrade to iOS 4.3.3 and my battery was slightly better, but it was still not too good (I restored as new). I ran a jailbreak on 4.3.3 for about a week and I had only slightly improved battery (Maybe an extra hour of life). Then I decided to Restore as new back to iOS 5.0.1 and re-jailbroke. For some weird reason, afte the second update to 5.0.1 my battery life has been significantly better. I get a good 7 hours of regular usage and 20+ hours of standby. If I use my iTouch 4G lightly throughout the day I can get 2+ days out of a charge on my 1 year old device. I unplugged it today at 100% at 4 p.m. and it is now 11:40 p.m. and it’s down to 10% after using it to stream netflix for about 2 and half hours, browse the web, download things from cydia and appstore, watch Youtube videos. This was with pretty heavy use and an hour’s standby time give or take. This was all with an Animated HTC Weather LockScreen running in Winterboard and numerous Glasklart HD theme components running. I am quite pleased.

  15. Anup says:

    I bought the iPhone 4 about a month ago. Upgraded it to iOS 5.0.1 when it first released. Before the upgrade I used to charge the phone every 2nd day. After the upgrade I’ve only had to charge the phone every 4th day. I’ve disabled push mail, facebook notifications, etc so I manually check them whenever I want to knowing that a lot of junk comes through. Wifi is enabled only when I’m downloading an app. Location services is enabled only for Locate my iPhone service. I’m quite happy with the battery life so far. I’m not a heavy user of my iPhone but its not left ideal too long either.

  16. sheraz says:

    I bought a 4s 4 days ago and with mail push off (i don use it) its giving me 2.5 days of battery life with 5 to 6 hrs of usage, full usage lasts abt 10 hrs which is what i use to get on my iphone 4, my ios is 5.0.1. GUYS A FRIENDLY ADVISE TO ALL OF YOU, WHENEVER THE NEXT UPDATE IS OUT WHETHER ITS 5.0.2 OR 5.1 PLZ DO NOT UPDATE STRAIGHT AWAY WAIT AND SEE HOW IT GOES IN THE MARKET, CHECK FEEDBACK AND THEN DECIDE…..atleast i am going to do so 4 sure… really loving my 4s…..

  17. Aaron Dwyer says:

    Apple have had this issue before high battery consumption with the 3G and it took them ages to work it out and fix it. I wouldn’t hold your breath. Aaron

  18. Adam says:

    I got the 4s the day it came out and I guess I’m one of the lucky ones because I have had no problems with my phone. Battery lasts 10+ hours active use and I can go 2 days without charging if im just making calls and texts and what not. I do hope however, they fix all the peoples phones that are having problems. Honestly I can say this post is probably the only one youll read with no problems and thats sad. I really love the 4s though it met my expectations.

  19. Stiggy says:

    Ever since I got ios 5 on 3 gs I can’t send mms its a joke!!!! Apple need to get things sorted or I think they will lose alot of customers. FIX ALL THE BUGS APPLE

  20. Jeremy says:

    I purchased a 3GS the day it came out, skipped 4, and purchased 4S the day it came out. On my 3GS i could do so much – take pictures, email, text message, use GPS apps, make calls, you name it and my battery would last.

    My 4S sucks. I contacted Apple and they sent me and wife replacement phones. Replacement phones same problem. Contacted them again and they sent me another set of replacement phones. They suck too. I loose about 10% in an hour or so, with little or usage. Little usage might include checking the time/battery on the home screen, sending one or two texts, taking a picture or two. Same rate of battery drainage if it simply sits in my pocket unused.

    Oh, and the phone gets quite hot to the touch.

    Really starting to hate the damn phone.

  21. iPhone Lover says:

    3GS owner and soon to be 4S. I have had my iPhone 3GS for about a year now, not that much of an issue with battery life. I play a lot of music, search the web, etc.. However, I am usually on a wifi connection when at home. When I’m out, I am on a 3G connection with a so-so downspeed. I notice my battery drains dramatically on the 3G connect without the use of Bluetooth or Location Services. I make it a point to have my traveling charger with me at all times, especially when using a map. The iOS 4 update was terrible in regards to battery life. The iOS 5 is no better than the update that came when I got the phone last January. Fact is, eliminating the push notifications and any heavy 3G required app, you’ll save a LOT of battery life.

  22. terry says:

    iphone 3gs. At noon everyday I now have to charge my phone. No problems before the new OS. The fix needs to happen soon.

  23. Haden says:

    iPhone 3gs owner here. iOS 5.0.1 was and IS still amazing, although they really needed to at least make a checkpoint and redeem themselves with iOS 5.0.2 and save all the problems. Not only does the battery life on my iPhone suck at this moment, but sometimes if I reboot my iPhone, it’ll start on bootup, my iPhone will shut off every 2-4 minutes or less and restart. I really hope this new iOS 5.1 hits iTunes fast, cuz it’s really frustrating.

  24. HJazz says:

    I have ipad and for more then a year i was using it intensively and the battery was around two days average
    After the Ios 5 “crissis” i am unable to get 4 hours!
    I was waiting 5.0.1 as the saver but the result was shocking and the iPad now is laying on my desk near “its charger”
    Apple, please give me my ios 4.5 back, i dont want your new version :(

  25. Hi says:

    3gs owner here. Battery life on my iPhone has always been superb before ios 5. My iPhone currently stays home since I have another phone for work. After unplugging the iPhone after a full charge in the morning, by the next evening, to my surprise, there was only about 25% of battery remaining after zero use! Definitley something going on here…

  26. IOS 5 says:

    I Have an Iphone 4 eventhough i updated to IOS 5.0.1 all is ok for me. I am a normal user about 10-15 calls a day. some messages and 3 email accounts configured. I get around 48 hours of my Iphone with no problems.

  27. dahlia says:

    i have the iphone 4 and i love it up until updating to 5.0
    my phone has to be charged a few times a day, my signal is awful, i get some king of memory error msg and to top it all I have to resend txts before they actually go through
    feeling frustrated, i totally hate my phone now

  28. 3021 says:

    For all people having battery issues for iPhone 4s there’s a permanent fix. It’s not hard to read forums you know…. If you want to fix your “battery bug” all you have to do these steps. Go to settings > General > Reset > Reset all settings (Note this will only reset your wifi pw, your configuration etc. It will not delete your apps,game data and contacts.) Once you resetted all settings, your phone will reboot and you will have to put in your wifi pw,apple ID,location settings etc. Then when it says if you would like to back up your phone via iCloud, Don’t back it up, just start as new phone. After that is done set all your setting like it was before. Your iPhone battery will be normal as what apple says. When that’s done let your battery drain all the way to 0% then let it charge for at least 4-5 hours with your phone turned off (this is a charge cycle and will recalibrate your battery). Trust me this worked for me and has worked for a majority of others as well(If it doesn’t fix then reset settings again, 2nd time worked for me). I now get over 9 hours of wifi and 6 hours of 3G, it’s been a week and the bug has not came back. Typing this on my iPhone 4s with 37% battery and 6 hours and 50 minutes of wifi. Good luck!

  29. Yuriy says:

    I have a question for those people that claim they DO NOT have battery problems with their iPhone 4s (Tom and Matt in this thread, and hopefully others). Could you please be more specific on several points:

    1. what battery life do you experience? – lasts a day, 2 days, 3 days, etc
    2. what carrier do you have?
    3. What is your iOS level?
    4. what features/apps do you use and how intensively?
    5. what features/apps do you avoid or turn off?

    Assuming the issue really does not afflict all users, perhaps we can learn from those who do not have the problem, or if the problem is truly hardware specific, demand that Apple replace our lemons until we get the “good” phones.

  30. Ben Rankel says:

    Add me to the list of the afflicted. This is my first iPhone and I do love it (reformed BB user). But I have to plug my phone in by noon/1pm EVERYDAY – and that’s after charging for the evening. I use twitter a bit and email as well as messaging but my battery seems to drain at the same rate regardless of whether or not I’m using the phone.

    It’s not such a big deal when I’m at work and can plug it into a charger for the afternoon but on a weekend when I’m out and about? It’s pretty annoying.

  31. Dallas says:

    I bought a 4s from Sprint at the launch of the 4s. I have had horable service from both Sprint and the iPhone 4s. My wife has an AT&T iPhone 4. My battery barely last through the day, hers last 2 or 3 days with similar usage. Her data speeds are 1 to 3 Mbps dowload, mine are 0.020 to 0.200 Mbps. (That’s right 20k). I have ran hundreds of speed tests. All test where both phones showed near maximum 3G signal strength. I have spent about 20 hours on the phone with the Sprint non-Help desk, had Apple replace the phone with a new one, and still bad results. The iOs 5.0.1 update did help battery life marginally. Before the update, my 4s battery would be in the red by lunch with virtually no usage.

  32. Jo Berridge says:

    This is my first iPhone my son n husband have the iPhone 4 and mine is the 4s. My battery life sucks before and after the update althought a slight improvement. The other thing I’ve noticed since the update is that Siri doesn’t work so well! Its understanding is now awful and cannot use with Bluetooth as that’s even worse!!! Since the update it forgets things to like my husband being my husband and constantly says “I can’t help you with that” this seriously needs fixing too! I swore I’d never have an iPhone,previously android user, got convinced to have the iPhone but now wonders if I did the right thing??

  33. Thomas Litchfield says:

    I’ve had three Android phones since the G1 came out in 2009. I never had battery problems with my first two phone, now I have an S2 and I can only get one day off a full charge on light usage. I wish it was better but seriously, with a 4.5″ screen, dual processors, wifi, 3G, etc. I knew going in that battery drain was going to be a challenge.

  34. Tom says:

    I have an iPhone 4S and a 3GS. The iPhone 4S never had any issues with any software version (5.0 or 5.0.1). My iPhone 3GS did have an issue, one, bluetooth was on, turning that off helped, and the 5.0.1 seemed to fix the problem completely on the 3GS.

    I don’t know how many people are having these battery problems, but I would expect it’s a very low number, just like very few people actually had problems with the iPhone 4 antenna issue. Less than 1%, and I think only people with complaints are reporting and blogging about it.

    I’m one to blog, I’ve never had a battery issue with my iPhone 4S, and with my 3GS, I think the Bluetooth being on was the bigger issue!

    I’m curious, how many android phones last all day and don’t need a frequent reboot? I know some are good phones, but might one say less than half of android phones do well day to day without charging during the day and rebooting after software issues?

  35. Adam says:

    My 4s battery usage WAS excellent, I could browse the net, play games all day, UNTIL i did the update, Now it drains really fast.

  36. Matt says:

    Not trying to discount others, but I have a Sprint 4s with 5.0.1 and my battery lasts for well over 36 hours on standby. Listening to music all day at work, it drains maybe 20%. Maybe this is carrier specific? My wife’s 4s from Sprint is the same way.

    Sucks others are having such bad issues though :(

  37. ATOM BOMB says:


    I agree with you 100%. The phone is amazing, however this battery is the worst ever. I too returned the phone to Apple and they did give me a new one, and this one is a tiny bit better.

    This is my first iPhone and have to charge it 2-3 times a day. I was on a conference call for an hour the other day and it drained 16%. 1 hour!!!!!! Even on stand by, I drain at 8-10% per hour.

    I hope the next software release fixes it.

  38. Scott says:

    I’m on my 2nd 4s with numerous calls to Apple and they refuse to admit there’s anything wrong. They say that my battery usage is normal even though I have to charge it twice a day. I’m done with apple products after this. Worst customer service EVER!!!!!!
