IOS 4.3.3 battery life has been significantly reduced

Not those either. 🙂 I was interested in the usage and standby numbers after you mentioned how fast your battery died. It looks like you rebooted your phone and will have to try another day.

ok.

It has gone from 92% down to 71% in 2 hours now ... and I havent used it really other than to email the screenshots.

Thanks

Silly question, but did you try a restore as new?

i restored to 4.3.3 yesterday ... but did not set it back up as a new iPhone in iTunes ...

Should I give that a whirl ?

I would restore as new and then give it a day or two.

done, will posts some results in 24-48 hours.

Restoring the iPhone as a new device will solve these battery issues which are being caused by corrupted software. Please follow the guidelines in the following article to do so properly.

So with my wife chatting a fair amount on my phone (her non-iPhone had run out of battery, ironically enough); with WiFi and Bluetooth on; though not connected to anything for the most part; and the battery is doing much better.

This is what I did: plug into computer, RESTORE via iTunes, and configured it from a backup. Had done the hard restart before, but didn't seem to make any effect.

I turned off the notification and geolocation as long as everything is fine.

I have the same problem after upgrade to 4.3.3. I tried all the solution, hard reset, restore, switch off notification. The only thing resolve the problem is to delete my exchange email account, re-setup it and turn off the push but using the fetch. My suspecious is the mechanism that maintaining the push connection drain the battery, regardless is exchange email account or not.

all,

I have an iphone 3GS and have experienced the same battery life issues since updating to 4.3.2 and 4.3.3.

I have turned off all settings which can cause an increase in connectivity (ie: WiFi, Personal Hotspot, Notifications, Location Services), I also turned off Cellular Data and Enable 3G, therefore only connecting to the mobile network via standard 2G connectivity and the battery life still suffered.

Therefore my suspicion is the ios 4.3.2 or 4.3.3 is regularly communicating with the mobile network (ie: location updates which mobile phones do).

The battery has been hot too.

Lets hope we get an update from Apple soon.

regards

the problem hit when I installed 4.3.2. but has been significantly mitigated since installing 4.3.3 and permanently switching 'location services' to off. unfortunately i did both at the same time so i can't tell which had the effect. i leave 3g off unless needed but have wifi on most of the time unless i am in the car when i turn bluetooth on and wifi off

Battery life on my 4G Touch is significantly reduced since installing iOS 4.3.3. Resets, turning off location tracking, bluetooth, etc. doesn't fix the issue.

I won't install it on my iPad2. Waiting for an update from Apple.

This is getting absurd. I have never had battery “issues” with my iPhones – well both my wife and I thought we did with our 3G’s before discovering the magic of a restore-and-start-up-as-a-new-phone trick. I began with a fully charged battery on my iPhone 4 the morning of April 29. Perhaps four hours later, the phone suddenly went dead – I only noticed this because I was getting voice message emails (I use Yap) and I hadn’t heard the phone ring. I plugged it in and tried to bring it back with a hard reset, no luck. Got online and was able to get an Apple Store appointment that afternoon – I was leaving on a one-week business trip May 1st and I use this as a work phone. The folks at the Apple Store did get it going again but did say I might have to do a restore. Rather than waiting for the need, went ahead and did so as soon as I got home. Given that I was choosing not to use a previous back-up and bring it back as a new phone, it took several hours to painstakingly put the apps back where I wanted them, bring back my music and restore all my mail settings and other preferences exactly as they were before. You could almost watch the battery drain. Left on my trip and was getting maybe three hours out of the battery. Forwarded my iPhone to second cell phone and turned it off (one of the problems with the smaller SIM – you can’t just swap it out to another at&t phone). Got online again and set up an appointment with my Apple Store for May 5 after landing SFO – no Apple Stores in downtown Atlanta. To make sure that it wasn’t an errant app, I did another restore the morning of the 4th with a new phone setup and un-ticked the sync apps radio button. Loaded no music but did put my MS Exchange account on the phone. Still could watch the battery drain.

They did a complete diagnostics on the phone at the Apple Store on the 5th and the battery was fine. They did notice, however, that usage and standby times were exactly the same and thought that odd, especially since I wasn’t running anything but stock applications and Exchange. They gave me a new phone. Got home last night and plugged it into iTunes, new phone, brought over all my apps and music. Set up my Exchange account. Same **** problem – battery drains fast and usage times and standby times are exactly the same. I’ve been playing with the Exchange account – deleting it, rebooting, and so forth and this may be where the problem is but this was never a problem before. Never. What is truly frustrating is that my wife’s 3GS is getting a full day out of a charge, her usage times are much lower than her standby times and closely approximate the minutes that she actually seems to be using the phone, and she is running push on an MS Exchange work account as well as a POP 3 personal account.
