IOS 4.3.3 battery life has been significantly reduced

Hi,

I was trying my luck last night. Turn back ON my PUSH to Fetch New Data, with my Exchange Email (Work Email) & Gmail activated.

All other applications, including WIFI, Personal Hotspot & Bluetooth are all closed & OFF.

To my surprise, after 13 hours (mostly on standby mode), my battery is still at 85% level !!

Didn't do anything to my iPhone 4...never restore my iPhone too...only did a sync to my iTune software...

Allright so i did a full restore yesterday - didnt sync my contacts,emails nor calendar and just imput them myself - i had most of my contacts on my sim card so it wasnt so bad:/ sadly , the battery still drains much faster than it did on 4.2.1 but through the night ( about 6-7hrs) it went down only by 1% which is good comparing to 4-5% it did before the restore.

I also did a downgrade a few days ago to 4.2.1 which was perfect for me as far as battery lifetime is concerned and the battery drains as quickly as it does on 4.3.3:/ So up to this moment i have tried every method that is mentioned here and on other forums and in my opinion - this must be the software bug which HAS TO BE FIXED BY APPLE KN THE NEXT UPDATE.

Agreed Problem! I turned off Apple Store as recommended elsewhere in these posts with no avail. After charging all night and up to 100% after unplugging from charger the phone has drained to 82% power and it is still morning. This is much worse than it has ever been before.

Apple Needs To Fix!

Battery life on my 4G Touch was significantly reduced after installing iOS 4.3.3.

Here's what has worked for me: I've turned off location tracking, fetch, bluetooth, ping, etc. plus I'm leaving Airport Mode "on" and toggling WiFi to "on" only when I need it. Hence, I only turn WiFi "on" when I need to access the Internet.

When I'm not using the Touch Airport Mode remains "on" and WiFi is "off."

Battery life has significantly improved.

See if this works for you.

This seems ridiculous to have to cut half of the applications that, before the install of the new system update, were all working with no harm to the charge-holding ability of the iPhone 4.

Can the new update just return us to the old update? Things were working fine then.

This morning at 100% down to 82% within a few hours, down to 57% by evening and now at 42% at late evening. I have done nothing with my phone today but take a few calls. It is draining like a sieve.

Please throw us a life line Apple,

Ken

Here's my update. Two iPhone 4's both at 4.3.3.

My battery went bad so I did a complete restore, setting it up as a new phone. No problems since doing that - at least 10 days or more.

My wife's iPhone 4 had the same problem so I also did a complete restore, setting it up as a new phone. It continued to have problems, so I did the "fix" again. This time the battery life appeared to be even better than it was weeks earlier. But that only lasted for a couple of days, then all of a sudden, WHAM, it started losing its charge quite rapidly. Last night, during the night, it completely drained.

I have a Genius appt this morning. I know that they cannot fix it, but I figure, the more people that complain about it, the better.

For the appt, I'm charging it right now, then will not touch it until my appt time, just to see how much charge is lost without even using it.

But for now, the only way to feel safe about it is to always be near a charger.

I can't believe that I haven't heard anything about this problem on any Apple podcasts or on any of the rumor sites - not a word.

Has anyone noticed this issue ?

I plug my iPhone 4 in every night on my nightable, but leave it on due to the nature of my job. My phone can ring at anytime of the day.

In the morning after 8-10 hours of being plugged in, I unplug it and the battery is only @ 97-98% charge ... never 100%.

Today, I've been up and around for 1 hour, and my battery is now @ 91% and all I did was read a few email and thats it.

Once again, Location Services are off, PUSH is off, Signed out of Apple Store, Calendar is off (which is a pain in the *** with all the meetings I have every day, etc ....

I think my old 1980's brick phone had more features and a longer lasting battery.

I'd take the phone back to the Apple store, but why? They cannot fix it and a new one will likely have the exact same issue.

This is almost a waste of breath, but I did turn off my phone last night, completely off, with the battery charged at 95%. This morning I turned the phone on and it was still at 95% - So that much proves that only when the phone is on will the battery drain like a kitchen sink.

Is it an Apple 'cover up' that they have not mentioned or come online here to acknowledge the problem? It is always better customer relations to fess up and at least say they are 'working on it.'

Sheesh,

Ken

Well,

For the third time in 2 weeks, I have just restored as new AGAIN .... I couldnt even get 1/2 - 3/4 a day out of the phone with everything turned off and minimal use.

I'm going to use it as is, meaning not changing a thing after the restore and see how it goes for a few days.

Other than to prove a point, this is completely useless to have a phone with no calendar, email, contacts, GPS, location services, etc ...

Stay tuned as I grumpily (is that a word? 🙂 ) use my iFlipPhone now for a couple days.

P.S. - I just followed the link that "Allesa" posted above. WHAT A JOKE APPLE.... "up to 300 hours of standby" must mean when it is turned OFF ?

iPhone 4:

Talk time:
Up to 7 hours on 3G
Up to 14 hours on 2G (GSM model only)

Standby time:
Up to 300 hours

Internet use:
Up to 6 hours on 3G
Up to 10 hours on Wi-Fi

Audio playback:
Up to 40 hours

Video playback:
Up to 10 hours

Yesterday's success was apparently a fluke. It was not uninstalling those apps that made my battery lasted longer.

This morning, after I unplugged the phone after a whole night charge, in less than 15 mins of use, the battery goes down 2%.

However, I may found something else. I was using SYSINFOPLUS app, when I found that my load average has been about 1.5-1.7 (read somewhere that it shouldnt reach more than 0.0-something on idle. Yesterday, when the battery was "ok", the 1,5,15mins load were around 0.30-0.40.

The second thing I noticed in SYSINFOPLUS was: under "LOGIN USERS" in the "SYSTEM" tab, there was no user logged in. Yesterday, if im not mistaken, the list wasnt empty.

Therefore, I opened up terminal app then logged in as root. All of a sudden, the load average decreased to 0.02-0.1 on idle. Now the battery is still hanging on 100 % after 1 hour of fiddling around.

I'm no tech or IT expert, I honestly don't know the connection of what i did and the battery drain.

Please try this fix out.. Thanks.

Have you tried this solution, originally posted by Hankerin?

I can safely say that with my phone it definetly has something to with my MS Exchange calendar - not mail, not contacts but calendar. We're using Exchange 2003. I've done probably twenty restores - all as a new phone. And through trial and error was able to substaniate that at least with my iPhone 4, it was the calendar in Exchange which is now set to OFF (and syncing with a USB connection). I've got Push going, BT on, 3G on, location services on, logged in on the App Store - pretty much everything ON that folks here have suggested turning OFF. The phone was pulled off the charger at 5:30 AM yesterday (Tuesday) and I'm at 41% today (Wednesday) at 4:23 PM (nearly 35 hours). The only charge it has seen at all in this period was maybe the two minutes I had it connected to my laptop for a calendar sync. And I can duplicate the issue at will merely by turning the calendar ON. And fix it by turning the calendar OFF. And I've put all my apps and music back on the phone. I sent a bug report and will continue to sync my calendar through the USB connection until we see another update. Hopefully it'll be fixed then because I use the calenar a lot and syncing as I am now is a royal pain. Never experienced anything like this with my 3G or the 4 (which I've had since the day it was released).

I turned off Exchange Calendar Sync it the problem was resolved for my 3GS, too.

I even confirmed it with an app called "System Status". I could see that, when Exchange Calendar Sync was activated, my CPU load was almost constantly at 100%. After disabling Exchange Calendar Sync, it dropped down to a reasonable average around 5%-10%.

This issue did not exist before 4.3.3, so it is a bug that needs to be fixed in a subsequent iOS release.

Replying to my post about my wife's iPhone 4.

It went completely dead over night. When I woke up, I charged it until 9:30 when it was full.

We had a Genius appt at 11:30 so we didn't touch the phone until then. The charge was at 99%.

The Genius could find nothing wrong with it using the diagnostic tools that they have.

Since then, it's worked wonderfully. It's hardly used any battery at all under normal usage.

I've seen other posts about letting the battery drain completely. Maybe that did the trick this time.

I beg to differ. The issue has existed with every release in the past 3 1/2 years going back to 2.0. It only affects a few phones each time, but it has been a persistent problem since the beginning if iPhone time. It can also happen spontaneously weeks or months away from an update. And the solutions have been the same since release 2.0.

It is not one problem; it is a symptom of a problem, and the potential causes are many. Virtually all causes are related to applications sending or trying to send data continuously. Which is why you see so many solutions in this and other threads that work for some people, but not for others.

Havent had any problems since upgrading to 4.3.3. iPod touch 4G was 5 months old and supposed to have a powerful battery, yes it has, and yes, didn't have any problems with the new iOS.

PUSH email- OFF

PING - OFF

Bluetooth - OFF

Location - OFF

Notification - OFF

Airplane mode - OFF

Wi-Fi - OFF (On only when needed)

Appstore - Signed-out

Played music and set the volume to 70% from 9:00 PM 100% Batt to 8:00 AM 68% Batt - Battery consumes 32% - Music are mp3 and 320kb bit-rate.

No theme just a wallpaper, non-JB, about 70 Apps, birghtness set to 35% I guess, or 40%.

When I play a heavy 3D games, such as (Epic War TD, rainbow six, etc.) it consumes lots of battery charge but I can play for it for 3 hours and still has 22% battery.

I tried to set all those to ON believe me it didn't have enough impact to drain battery so quickly. But the hours of using it of course will reduce because all features are enabled even if I'm not using it.

But for some reason, mostly on iPhone4 & 3GS, issue with battery on 4.3.3 occurs.

Turning OFF features is not a solution. There are lots of iphone users uses most of iPhone features and we cannot let them try to turn OFF what they are using or restore the iOS etc. etc....

There must be some terrorist inside iOS 4.3.3 that terrorizes the battery even in idle mode. But some iPhone users when turning OFF the features, battery went ok.

If you analyze all issues been posted in here, I agree... Yes its iOS issue. not a Hardware fault.

I'm just sharing my 2 cents m8s.

Last night my iPhone 4 suddenly drained very quickly (1% every 2 minutes) after I changed an entry in my phonebook. The phonebook became hanging and slow and jerky in scrolling. So I remove all entries in my phonebook and resync. Now the battery life is so good, only used up 20% for a whole day with wifi, push email on.
