IOS 4.3.3 battery life has been significantly reduced

I have done it all and seen some results ..... Sad to say I got a total of 8 hours us out of my iPhone 4 today under what I consider nominal usage (handful of calls, few short surfing periods and sombiasic email activity.

Not sure what to do, Apple doesn't appear to be listening at all.

Very disappointing to say the least. NO repeat customer being made here !!!!!

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.

My iphone 4 4.3.3 battery life has suddenly got so much better after a week of trial and error. Before, in standby with no features on except 2g data (edge) my phone would reach 15 percent battery drain overnight. Yet last night, with edge and wifi on, gmail exchange on push, only 2 % drop over 6-7 hours.

Sadly, i'm not really sure what fixed it.

My previously futile efforts include:

-restoring as new phone

- hard resets

- battery recalibration (drain to below 10 percent and then topping it up)

- turning off appstore

- brightness auto

- turning off push for mail

- deleting mail accounts

- reset network settings

- turned off ping

Here is what i did before the battery improved:

- Sync with itunes

- charge multiple times over the period of 5 hours, whenever the battery reached 75-80% (it drained to 80% from 100% in about an hour or so with normal usage, mostly chat on yahoo messenger and 5 minutes browsing )

- log out of facebook

- deleted pingchat

- deleted tweetbot

- deleted echofon

- deleted foursquare

- deleted an indonesian made gps app

- deleted facebook chat

- deleted spotify

- deleted snatch

- deleted skype

- Uninstall several JB apps such as mywi, 3g unrestrictor, insomniac, openSSH, notified pro, firewall ip, and some other i regretfully forgot (in general it was apps that either tweak internet connection or utilize it)

After automatically restarting after the last uninstallation, the battery got better. Almost 6 hours non stop browsing, chat, downloading, facebook updates tweeting and checkins with hootsuite, 30 mins phone call, 5 pictures taken with flash, instagram, all done on 3G, exchange push on, battery still at 30% from 85% when i last unplugged it. This means it lasting as how apple advertised it (http://www.apple.com/iphone/compare-iphones/).

Dunno if it is really fixed or i just got lucky and the problem will recur. I hope this helps.

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

I don't think I've ever seen Apple reply to any posts in these forums. They may not even monitor the forums.

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

Almost 2 hours, and I have NOT even dropped 1% ......

Previous to this, I could expect 10-20% per hour ...

Something funky going on with the software.... BIGTIME

Apple are too arrogant to answer their critics let alone produce an answer to this problem - but they monitor these forums. I doubt it'll be long before this posting is deleted.

Now at 4.5 hours ... still the SAME battery ... with only a 1% drop in total ... (on standby, I havent used the phone)

Hmm, Not sure what else to say.
