IOS 4.3.3 battery life has been significantly reduced

Sorry, just passing on what the "Genius" told me. Don't shoot the messenger and try it first. Working for us.

I'm not shooting you. 😉

I tried it already in the past. I had no bg tasks and batterie was empty after 8-10 hours of standby. 😠

btw. now my doughter lets sometime 10-20 games open in background, also wifi is on and the batterie last for 2-3 days without charging.

Battery life *****, anyway.

My iPhone 4 works fine since doing a full restore - set up as a new iPhone.

My wife's 4 did not have better battery life after doing that the first time, but I did it again and now it's great.

Actually, it might be better than it was before the problem started.

It doesn't matter anymore Apple's screwed the pooch. The know about the problem but aren't talking about it. Typical corporate crap.

I've had enoubh. I'm going android!

the problem isn't settings. IT IS THE SOFTWARE!!!!

Correct.. Turning off all the settings defeats the purpose of having an iPhone... You may as well go get an old Motorola Brick phone.

I read on another thread that Apple does not test new releases of iOS against all versions of firmware. Which is why some phones don't have any problems and some do...

There is a bug in the software.

Agreed sas2399 and Sevenfish...but it's another work around till Apple gets off their arse and fixes it.

I was told the same crap by the 'genius' bar when the 4.3.1 update caused battery drainage issues on my iphone 3GS. It's rubbish. At that time my phone was just over a year old. I was also told to get a new battery at £60 and that I should've bought Apple extended warranty.I managed to resolve the issue by deleting some apps I suspected were causing issues by constantly reloading as they weren't compatible with the new update. I also found that as more apps got updates the battery life improved. Then 4.3.2 came and the issue started again. Then 4.3.3 and its bad again, now charging 3 times a day and not even using as I normally would. I don't use Push and I've disabled Ping so I know its not that. I've done a hard reset and also restored. Still no change. If I got to bed with almost 100% by the times its morning its dead and I'm not even using the bloody phone! 😠

I am encountering the same battery drained issue after upgraded to the latest 4.3.3 IOS.

Closed all applications didn't help.

Hard reset the iPhone4 also did not help.

I finally pin-pointed to Email Setting: Fetch New Data setting. Turn OFF the "Push" setting & select "Manually". Batt life greatly extended after this selection.

Prior to upgrading to the latest 4.3.3 IOS, I did not see this batt draining issue even with the "Push" set as ON.

Unfortunately now multi-tasking has been introduced into IOS, being able to quit applications is a very important thing.

There is no way (as far as I know) to quickly quit all open applications, or to quit them all except the one currently running. You have to do it in various fiddly stages. This would be a very useful addition to the next OS.

I charged my phone last night till 100% using battery doctor pro, after that I went to sleep, and this morning it still stands at 100% . I didn't turn on airplane mode btw, but 3G & Cellular data was off though. Last time, it used to drop 1 or 2% for the whole night.

However, now at 10pm after I wake up and use the phone since this morning 8am, it stands at 36% with some usage. Including Whatsapp and messaging, few phone calls, all less than 1 minute. Some 3G Web browsing when I was bored (3G was on for about 30 minutes) , and some games. and I can see the % drops in minutes with 3G on. Btw, I didn't turn on WIFI for the whole day.

Is it normal ??

Settings was :

3G : Off most of the time (Only use when I was bored for that 30 minutes)

Cellular Data : On all the time

Push : Off

Notification : On

Location Service : On

Btw, I have DataMan running in the background all the time.

Try calibrating the battery.

Yesterday morning I drained the battery of my 3GS under normal use, went to full charge around noon. Afterwards I used it as normal, some text messages, about an hour of music play, then the alarm clock this morning, some text messages, about ten minutes of talk time and now in standby in a low reception area (which consumes battery quite a bit due to constant signal tracking). It's past noon today and the battery is at 79% after its full charge 24 Hrs. ago.

Compared to the battery drainage that was taking place the day before yesterday this is quite an improvement, even more considering the low reception area in which the phone is at standby right now. This leads to a probable battery calibration issue instead of the whole reset hassle, which may not solve anything, really.

I still believe there's a problem with iOS4.3.3 regarding battery consumption which needs to be fixed, however I suggest to give it a try with battery calibration, it might do some help, so far it has done for me.

ROFLMAO

Agreed on software causes battery life to diminish quickly. My healthy iPhone 4 has never had a battery life issue until I installed the new software update. Highly suspect at being the cause. My phone now drains every day where it used to always run like a champ all day and still have half the battery power left. Now it drains to 20% in one day. Very Bad!:- (
