Jobs unaware of iOS 4 battery drain issues?

updated 09:40 am EDT, Thu July 8, 2010

CEO dismisses problem with upgraded devices

Apple CEO Steve Jobs is either unaware of battery drain caused by upgrading older handhelds to iOS 4, or dismissive of it, information from a Norwegian journalist suggests. Jarle Aasland explains that he recently sent e-mail to Jobs complaining about the battery performance of his iPhone 3GS. "Any reason battery performance on a 3GS running iOS4 should be worse than it was running OS3?" Aasland wrote. "Nope," reads Jobs' reply.

Numerous complaints have been made at Apple's support forums so far, which should suggest that at least some at the company are familiar with problems in the new firmware. No particular activity seems to be linked to high battery drain; killing background processes has no special effect. Even turning off GPS, Wi-Fi and Bluetooth may leave a device with less than a day of standby power.

    Good answer

    All of these emails direct to Steve Jobs are getting silly. If my car starts making a funny noise, I take it to a mechanic and have it looked at. I don't email the CEO of the manufacturer and ask him why.

    Why do people feel compelled to write to Steve Jobs over these technical issues?

    I have noticed it too...

    I have an iPod Touch 2nd gen, and I upgraded to iOS4 and noticed my battery drains noticeably faster. So, I believe the emailer might be onto something.

    Because the silly man answers, if he did not answer then there would be no point asking.

    I am not seeing it

    I have been running iOS4 on my 3Gs since the day it came out, and if anything, my battery life is better than it was before. I have been very happy with it: it is fast, smooth and much nicer with the multitasking. My only complaint so far is that not all apps have been updated for compatibility with background processing.

    OMG there are bugs with everything and its not just Apple. the media has blown this way out of proportion and people are trying to take advantage of the new iPhones little issues.

    Why hasnt the new Xbox360 made so much media buzz even thou im already reading reports of it having the same RRoD issue? seriously, MS has been putting out subpar products for decades

    i have a 3G iPhone and installed iOS4, i knew the draw backs and risks. I liked it overall but it slowed ny iPhone a bit and decided to revert back to OS 3. no big issue and i cant wait to get the new iPhone

    Keep up the good work Steve, I back you all the way!!!!

    RE: I am not seeing it

    I'm not seeing a difference of battery charge on my iPhone 3GS either and iOS 4 runs great on it.

    What I find comical is how much is read into SJ's one word reply.

    It's possible that if your battery on your 3GS was at that point where it needed to be replaced anyway - remember, this varies from user to use based on usage - maybe iOS 4 pushed it over the edge.

    I pre-ordered my iPhone last year, so I've had it for over a year now. I find it hard to believe these a battery drain issue on only some of the 3GS iPhones and not others, ergo, replace your battery and see what that does for you.

    My iPod Touch 2G has this issue

    Sometimes I go to bed with my iPod showing a full charge. Next morning, after doing nothing all night, when I go to use the iPod it gives me a low battery warning. Plus, the battery just generally depletes more than it used to. No big deal since I am always near power and can charge it, but still it's a fact that this has happened since the upgrade.

    Cut in half

    Battery life on my 3GS has roughly been reduced to one full day of usage with IOS4 compared to 2 days with 3.1.3

    I am seeing quicker drain on my 3GS

    I barely use any apps via multi-tasking and I'm noticing my battery drains quicker than it did before the iOS4 update. But I also noticed that several native Apple apps - Camera, Mail, even Settings – respond slower or freeze on a regular basis. Something that almost never happened before iOS4. Clearly something is wrong; perhaps it's the multi-tasking everyone has been begging for, or maybe it's just a glitch in the software or firmware; or the coexistence of apps updated for iOS4 and those not updated.

    Not seeing it on a 3G

    Yeah, I upgraded to iOS4 on my 3G the day it was available. Don't have any objective data, but subjectively, battery life is equal or perhaps very slightly better. Same is true of my wife's 3G.

    I suspect this is a case of bandwagonism, at least as far as the 3G model is concerned. 3Gs may be a different beast since it supports more features of iOS4, but I remain strongly skeptical of that claim without objective data.
