As for battery issues, I have not seen any on my 3G, however, I have noticed my phone is much more sluggish.
What battery drain issue?
My old 3GS battery life improved. I gave it to a buddy of mine and he even mentioned he could go all day with it in comparison to his old 3G.
this is headline news?
I upgraded my iPhone 3G (not S) to 4.0 and have not seen any difference in battery life – neither better nor worse. Of course I’m not multi-tasking so really the only benefit has been the app folders!! Love em
Mine is better.
Mine too. Battery is ok but games run very sluggish. Angry birds runs but will stop and start
I upgraded my iPod touch and it is always dead. I had it connected for the last 2 days, ejected it and went to work. I just tried to turn it on 4.5 hours after disconnecting it and the battery is dead. The last time I tried to use it, the battery was dead as was the time before that, all since I upgraded it to v4.
It hasn’t been used since the upgrade since I have an iPad and have been playing with that.
It appears there is a battery drain issue.
I honestly have not noticed any significant battery drain difference since upgrading to iOS4 on my 3GS, even with several apps running.
Well, I am still waiting for my iPhone for while using my 3G but would surmise that the more apps there are running in the background on any iPhone the more the battery will be called upon.
Just who is this idiot in Norway – any expertise other than ability to use a keyboard?
It was well worth upgrading to the iPhone 4, because my battery life is SIGNIFICANTLY BETTER on the iPhone 4. I can now go 2 full days without a charge. Amazing!!
Mine is better, too…..
It happened to my 3G after upgraded a week ago. However, it only happened once since the upgrade. Never been able to replicate it since then.
I haven’t noticed any unusual battery drain on my 3Gs since updating to iOS4, but I have seen some sluggishness if I have a lot of apps residing in the multitasking bar. Yeah, I know… most of them aren’t really running there in the background, but wiping everything off that list does resolve the sluggishness.
I noticed my Samsung’s phone battery life got worse when my wife upgraded her iPhone.
I should e-mail Steve…..
This link to Roughly Darfted has some info on improving iPhone 3G performance.
http://www.roughlydrafted.com/
My 3GS/iOS4 runs snappily, but battery life has taken a big hit.
My wife’s iPhone 3G will stay in 3.X. The advantages that 4.0 bring to the table are simply to meager balanced against it’s disadvantages. If you think about it, they made it compatible enough, but it is truly optimized for the new hardware.
Haven’t noticed battery drain but my 3G but it definitely doesn’t like iOS4…it’s slow and glitchy now. Good thing I’m upgrading.
My 3GS runs out of battery considerably faster after upgrading to iOS 4. Trying to rationalize my usage now.
I’ve seen no difference whatsoever. If the guy is having battery problems since updating to iOS4, he needs to simply do a full restore then.
what battery drain “issue”?? no problem here, 3GS w/iOS4 – battery life at least same as before
BTW, I’m waiting to see someone send an email to Steve Jobs that goes like this:
“Steve, are these email replies popping up all over the internet REALLY from you?”
to which he answers:
“Nope.”
Just wait…Apple will release a software fix to make the battery icon larger as it decreases in power, to better reflect the actual size of the battery.
My 3G battery had noticeably worse performance after an iOS upgrade. However, my wife has had no problems with her 3GS.
Okay, I am this >< close to believing that almost everyone in the world is fucking retarded. What’s next? “Did Steve Jobs know that iPhone 3GS cases don’t fit the iPhone 4?” “Did Steve Jobs know that his new iPhone 4 requires a new OS?” “Did Steve Jobs know that the new screen doesn’t let you see the pixels at 12″?”
Where was all this hysteria when Microsoft was ushering in the Dark Ages of computing? Where was the non-stop worldwide assault on Microsoft for ushering in the age of viruses, trojans, malware and botnets?
In the words of Ellen Ripley “Did IQs drop sharply while I was away?”
I sent an e-mail to Jobs awhile back and got no response. Apparently I’m in the minority.
No difference in battery life since upgrading my 3GS to iOS4. Only difference is that my car interface will no longer work with my phone.
I see battery charge hold improvement in my 3GS (turned iPod touch).
My 3GS is definitely worse. The battery drained yesterday when I did nothing but check emails and listen to a couple of podcasts. It’s been like that since the upgrade. I thought it was a hardware issue as I’m also getting black outs, lock ups and random resets losing all my 3rd party apps. Supposed to get a replacement phone today. Now I wonder…
My battery life has decreased dramatically. Probably because I now let Pandora run all the time..
” width=”19″ height=”19″ alt=”wink” style=”border:0;” /> Well worth the decrease.
I reported on iOS 4 launch day that my 3GS battery was draining VERY fast. I’ve gotten into the habit of killing all background apps . I know they aren’t supposed to use power in background state, but something was sucking down juice. Sorry, but the issue is real under some circumstances.
I saw a slight decrease after first upgrading my 3g.
I’ve since done a hard reboot to see if it will settle crashy apps, so haven’t observed any changes yet.
However, I think I have an idea why iOS4 would drain battery more that previously. Folders. Think about how OSX renders icons, folders, desktops, etc. as opengl layers for all the fancy transitions, zooms, etc. All that info is stored in cache to make things run smoother, so if you have a lot of folders on your home screen, they are all in RAM and using more memory. Don’t know if that’s a possible answer, but it feels right.
Oh, and Macdailynews? Please trim the bloated ad-choked site. I know you need to make a living, but wow.
Jobs is unaware of a problem that never existed. He is also unaware of the swine flu virus that is killing us all, because it never existed.
Any other dumbass articles written for click whoring? The US is click whore heaven. Grow the fsck up, pussies.
@CitizenX: I upgraded my iPod touch and have seen multiple issues, but battery drain doesn’t seem to be one of them. I’ve noticed no real difference in battery life.

To anyone who suggests there are battery drain issues with iOS 4, look to the apps you are using. If you see a purple arrow in the upper right corner if your screen, this means that an app is running in the background. It could be that some of your apps are either poorly written or have not yet been upgraded to the latest APIs.
I was very careful in my choice of apps and as a result have had no performance decline in either speed or battery life on my 3GS.
I would suggest that this herring-eating Norwegan journalist is just plain wrong. Get a brain, fish-breath.
I got a brand new 3GS just before the iPhone 4, (insurance replacement) and it worked fine for about two months, then I upgraded to iOS4. Ever since then, my phone randomly crashes during calls and reboots itself. Once it happened 3 times within a 25 minute conversation.
Anyone else? It is quite annoying and happens fairly regularly.
J
Haven’t had any issues on my 3G with iOS4
Sounds like an IU problem.
My 3GS is on and off, there are days when I have to charge daily, but sometimes I can go few days w/o charging.
When I see my battery drains fast, I reboot.
And BTW, you people wanted multitasking, well, don’t complain about battery problems now. Ha, ha, just kidding.
No problems with my 3GS. Runs the same.
@ Brian
The purple arrow indicates that your iDevice had accessed Location Services, not that multiple programs are running in the background. Get it right!
=:~)
Got an iPod Touch with iOS4. No battery problems here
My 3GS battery certainly seems to sustain itself longer since I upgraded to iOS4. No complaints from me about anything regarding my iPhone. But then again, maybe I do have a life and have better things to do than rant about alleged problems.
How much of the problem is just due to an older battery? Most 3Gs are probably 2 years old, and 3GSs are probably a year old. Maybe the phone just needs a new battery. (I didn’t really notice any problems with my 3G when I upgraded — I wanted to get the iBooks app, and I now have my iPhone 4 but I’m having trouble with activation.)
iPod Touch G2 w iOS4 here. After the update Ive got:
Sluggish controls, lousy batterylife, apps and games crasching an the iPod restarting when I tried to open a pdf in iBooks.
I want a fix on this thru either a new upgrade or instructions on how to downgrade. I love the folders but I love being able to use my apps and games more.
Of course lord Jobs knows of this – still another in your face dismissal of customer concerns.
Keep it up, Steve, my boy – and one of these days, you will regret your amazing arrogance.
I wondered if it was my imagination or just the fact that my iPod touch is approaching its two year mark and I use (and recharge) it a lot. But I’ve sensed I’m not getting the run times I used to. Even thought of buying a small external battery unit. Yes, I recently upgraded to iOS4.
My battery life is noticeably better on iOS 4.
Battery life on my iPod Touch 3G 64 GB is definitely shorter (I’d guess about a third)
Wifi hanging on while dozing is my guess
@Chas….thanks for the correct info…I had instantly pulled out my iPad and started looking for purple arrows to see if it applied to the iPad as well.
I have noticed my 2nd Generation iPod touch is more sluggish with iOS4. I have not noticed a battery life issue but that’s doesn’t mean anything.
I did run into a problem with battery life after upgrading my 3GS to iOS4. Found the problem to be Trapster – after it is started it keeps using GPS until I remove it from the recent app area. There are a few threads on Apple’s website. I think someone may have also mentioned AroundMe as well, though I don’t normally use it.
I am one of those who has had the issue with battery drain. I posted a simple survey to try to gather data on what is happening. Admittedly, those who are responding are probably those who have the problem, so the data is probably skewed, but at least it is an attempt to collect information. You can view a summary of the results here.
I would welcome responses from people that are not having the problem, too. Some people having the problem and others not does not mean there is no problem at all, it just makes it harder to diagnose. I think most people on the discussion forum are trying to find a solution. People do vent, of course, but in the end most would like to see a solution, whether it is a suggestion on what we should do to solve it or an update from Apple.
If you want to add your own response, you can do so (a href=”https://spreadsheets.google.com/viewform?authkey=CIbi0LwC&hl=en&formkey=dDg4Q0p5U1FJUWd5VzN2Q29XM0lLQ3c6MQ#gid=0″>here</a>
Battery life on my iPhone 3G is definitely shorter after updating it. I think I will have to go back to an older system. 🙁
Is it me or has apple gone from media darling to let’s print every story that could possibly be negative.it’s what happens when you get to the top ,everyone wants to see you fall .plus if you mention apple in your story you get 10x the interest.I have stopped reading everything lately because of the negative slant ,but of course it’s happening all over America .instead of being can do and doers .we are becoming won’t do and complainers ,just my take
No battery drain issue here.
Jobs reply is perfect.
This issue requires more data before any coherent analysis can be made. I haven’t found any one hypothesis better than another at this point.
I definitely experienced a decrease in battery life after upgrading my 32 GB 3GS to IOS4. My “normal” use since July 2009 resulted in 1.5 to 2 days of battery life. Immediately after the update I couldn’t get a day out of it. As a test I completely charged the battery, locked the screen and let it sit for 8 hrs. The battery was down to 12%. Tried resetting the iPhone a couple of times, no improvement. Apple repalced my 3GS with a “newer” 3GS. Haven’t upgraded to IOS4 yet, establishing a baseline for battery life before upgrading.
After I updated my iPod touch, I notices that my batter sucks. After about an hour of browsing the web I’m at about 81%. Booo!
My iPhone 3Gs is slower, sluggish under iOS4, not a ‘huge’ problem but the finder is the biggest problem. I have 500+ apps on my iPhone, all but a handful are in folders. The finder seems to never find apps in folders right away, usually takes me three to four times ‘attempting to locate using finder’. That’s the major source of frustration.
I’m assuming its the folders causing the issue but that’s my uneducated guess.
I see a huge difference in battery life under iOS4 on both my 2nd Gen 32GB iPod Touch and my 3rd Gen 64GB iPod Touch. I think it’s shorter on my 32GB 3GS iPhone too. I thought Apple would know by now and issue a software update that would fix it. I love folders so I don’t really want to revert to iOS3 even if I could. Everyone I know is expiencing shorter battey life on all their old devices. So I thought it was common knowledge. If Steve didn’t know, he’s the last guy to find out. Here we go again…
Worse battery life on my 3GS, too.
Thank you, it’s very astounding information about this post it might be very hospitable for students.
Recently i needed resume company. To my admirable surprise, resume was worthy the price I paid for it.
I don’t know about you. but as far as battery concerned, it’s true. battery drain so faster than ever. I don’t know. do you use iphone as just phone? if you do, you don’t have any battery problem. I use it about 5 hours (combined with all purposes) normally. before 4.0, after using 5 hours, it still remained about 35%. now, I see red warning all the time, got only 10% when I go back to home. so yes, it is the true. battery drain on ios 4 is really a big problem. Apple should fix it. or it’s only for iphone 4.
“Wifi hanging on while dozing is my guess”
I think so too. My 2G touch has about 60% of the battery life it used to have for a very similar usage pattern, and it goes down quickly even when in Sleep mode.
I know it’s probably not optimized for the processor, but iOS4 shouldn’t drain the battery this badly.
The only pass way to get more information just about this good post is to buy written essay and buy essays.
Battery life on my iPod Touch 2g is WAY shorter. Did a restore and reinstalled apps without any iTunes music or playlists. I’m not jumping on the bandwagon to upgrade my iPad like I did with this upgrade.
As far as I know, there is no reason that battery performance on a 3GS running iOS4 should be worse than it was running the previous version of the OS.
Adverse battery experiences have been reported in this forum and elsewhere on the net, but it is not clear how prevalent they are relative to the total number of 3GS’s that have been upgraded to iOS 4. Like most other Apple issues lately, my guess is that the people experiencing problems with iOS 4 are being highly vocal, and that makes the problem seem more widespread than it actually is. I certainly hope that is the case…
@Jay
You might want to take your phone into the Genius bar. It won’t get fixed here…
My 3g had battery issues after I upgraded. I did a reboot and now have no problems with the battery. Battery life appears to be better than when running iOS3.
I’m not sure about the battery issue on my 3G, but it definetely has become rather sluggish! Sometimes more than others. I’m looking forward to September when I’ll update to an iPhone 4.
Only issues i’m having is listening to these rants.
I noticed an issue with battery life when I upgraded to iOS 4, but I found quickly found out why, when I used apps that used the gps of the phone and then used multitasking to switch to another app , the gps never turned off , therefore I was using alot more battery cause the gps was on, easy fix….. Just deleted any of the recent apps that used gps in the multitask bar, this info might help with anybody seeing battery issues
@KingMel, be assured that I am not merely “being highly vocal” about the decrease in battery life. The battery life is such that I have taken to charging it during the day instead of just at night. The hit seems greatest when using WiFi compared to previously. As others have mentioned, it’s possible some background aps are contributing to this. However, and I haven’t checked this out enough yet to be certain, it does seem as though the battery is charging a bit faster than before.
I honestly believe there is significant battery drain difference since upgrading to iOS4 on my 3GS, with several apps running.
On WiFI .
I fully charged my 3gs 24 hours ago, woke up this morning and it was completely dead. I used it for about 10 min of calls yesterday and 10 minutes of checking email. Prior to the upgrade I could get usually 2 full work days out of it.
@Hg Wells
Being “highly vocal” is not equivalent to being wrong. I did not mean to imply that you or anyone else way fabricating the decrease in battery life under iOS 4. What I meant by “highly vocal” is that people tend to speak up more when they are having a problem than when everything is going well. This can make a problem appear to be more widespread than it is in actuality.
My older son confirmed that the battery life on his iPod touch decreased significantly after installing iOS 4. I believe that our other two iPod touches (wife and older daughter) are too old to upgrade.
I don’t expect perfection, but I do expect the flaws to be addressed. History gives me confidence that Apple will isolate the iOS 4 problems and issue a software update reasonably soon. I hope that people give Apple a fair chance to make things right.
Any reason battery performance on a 3GS running iOS4 should be worse than it was running OS3…
custom bedroom furniture
Probably just reached 400 charges and ur batteries are only holding 80%. The timing adds up.
How do you know that he hadn’t been on a wait list? Besides, it’s not the same wait for everyone. It depends on if a liver that is compatible with the patient is available.
If we had nationalized health care, Jobs would die waiting for treatment.

I upgraded mine, and redid it a second time, both with the same results, I ca’t make it much past lunch time before I get the 20% of battery life warning. I used to make it until at least 7 – 8 PM before, and thats if i even got that low.
