iPhone 4 - ios 4.3 - Battery Drain

Hey guys,

I too have the iPhone 4 and was experiencing battery drain issues after installing iOS 4.3. I researched a few forums and found this potential solution on iLounge.

"Experienced the same problem. Fixed it by leaving my battery at full charge (connected to AC) and then powering off and syncing once. Perfectly fine after that. (I got the same issue in iOS 4.2. Same method to fix)

I tried it and it seems to be working so far (knock on wood).

1. TURN OFF PING
2. TURN OFF APP STORE
3. TURN OFF GAME CENTER
4. TURN OFF PUSH NOTIFICATIONS


Here is the solution that worked for me. Along with the normal Battery Saving settings, which I read from other forums like turning off location services and notification services, I also did a few other things. I activated the restrictions for Ping by Settings – General – Restrictions – Ping and turn it off. Also turn off the Itune, App Store, Game Center as well.
In, “Mail, Contacts and Calendar”, despite the obtain data for mail is OFF, meaning I had push notifications turned off and manual for data, there is another option inside this, called “Advanced” that is new to iOS 4.3. Inside this advanced setting, I realized that despite everything was off for mail it was still showing ON and continually sending / receiving data eating up battery and data. I turned it to manual too and made a reset for the network settings. Switched off and switched ON again. Now it looks like I have got my battery life back to normal.

Same issue here. After upgrading to 4.3 I more or less can´t use my iphone anymore like I did before. The battery empties without usage over night to 35%. During the day I can see the percentage shrinking. The is really a mess. Apple, please fixes this FAST!

There are several threads with ways to fix it. Apple is not going to, and saying anything to Apple here is like shouting in the wilderness, because Apple engineers don't read the forums. If you want to get Apple's attention go to an Apple store or call the iPhone support number. either will fix it, bus by using a rather drastic fix that will lose all your data. The tips you can find by searching the forum are less destructive.

I had the same battery drain issue after upgrading until I turned off Ping and let the battery drain completely then recharge. A simple reboot did not work for me after turning Ping off. I hope it helps the rest of you. I love Apple and their products, but it's a shame they would let a software issue like this ruin a great product. More extensive testing should have been done on such a mediocre feature such as Ping.

I also noticed the same problem and not just us. Several friends have noticed the same thing and also other people I know here in Brazil. I think Apple should give a quick solution to the problem, with the purpose of its customers and iPhone users are not prejudiced, for a long time.

In an earlier post I thought I'd improved my battery consumption, which I had to a point but still unacceptable. Last night I therefore bit the bullet and did what other topics on this aroubd the web suggested - a complete restore of my iPhone 3GS but NOT from a backup. I did a restore to new state and then manually synced my apps, mail, music etc. In 13 hours I have dropped to 88% and this is with Wi-Fi, location services, push email and all the other potentially battery draining settings on.

Forget the tinkering with Ping and all that stuff - it's a smoke screen I feel. A restore seems to be the only way to go. Of course you shouldn't have to do this after a software update and Apple really need to get their act together to resolve this, which is clearly related to the IOS 4.3 update.

I can't take the time to do a complete refresh. I have far too many apps that only save data within the app and don't sync setting to iTunes or dropbox. Having to go back and re-input all that data and re-populate my springboard isn't acceptable as a solution.

It wasn't ideal for me, but I am not a heavy app user and the time taken to re-do logins and so on for my few apps was a price worth paying. As Brian says, if you have masses of in-app data then its a no-no. Might be worth trying a reset & restore from backup, although I've read that this isn't usually successful.

The shorter messages tones were part of the update, not an issue with any update.

Powering off my iPhone 3GS and restart did the trick!

After doing some "trial and error" I have found that for MY iphone 4, when enabling restrictions to turn OFF facetime, by battery is back to normal. I followed ALLLLL the steps that everyone has offered advice on, including turning deleting email accounts completely, turning off ping, installing apps, signing out, restarting my device, restore from new, etc...but when running Netstat app i found that something was still causing for the push.apple green pin to still be on...so i kept trying different scenerios and have found that in MY case its the facetime that is killing my battery. After turning off facetime my battery is back to normal, just like when i got it!! I hope this helps all!! good luck!!

I don't know how the iOS 4.3 problems will be solved and if they will be solved.
Regarding my iPhone 4 updated to iOS 4.3, I've anomalous battery drain, anomalous data traffic and a worst function of the telephone.
I've tried all the suggestions I've read, without any solution to the problem.
Now I've solved using the iPhone only like a phone, switching off cellular data traffic.
I activate it only when it's strictly needed. And not always it works properly.
Now my iPhone 4 works like my previous 20 euros mobile phone.
Not very nice, if you consider that an iPhone costs more than 20 euros.
Deeply disappointed.

The ilounge solution has worked for me.

Charge to 100% with AC charger.
Power off.
Sync with iTunes.

Same deal here: iPhone4, no problems ever, but since installing iOS 4.3 the battery just drains superfast.
