iOS 4.3 battery drain

Just thought I'd add that I am on an iPhone 3GS with iOS 4.3 and my battery is draining at about twice the speed it used to be, based on exactly the same usage.

I've turned Ping off now in Settings > General > Restrictions as mentioned in an earlier post (copied here so people don't have to search for it :))... I'm holding out hope for this, since it's one of the new things brought in on 4.3. Will post back in a day to let you know if it's made the difference.

Yet another nail in the coffin for Ping :)

Incidentally, what a peculiar place to put such an option! Surely it should be under Settings > iTunes ? The Settings app is beginning to work like a bloated multi-tab Outlook settings pane. Apple really need a search facility for it!
 
My Solution: Let Apple deal with it

I tried everything suggested in this forum for my iPad now on 4.3. Nothing worked. My battery life was 2 hours of use down from about 8-9 from 4.2.1. I said enough and brought it in to the Apple store. They replaced it with a "new" iPad which still happens to be on 4.2.1. No more apple updates for me. I keep getting burned. Anytime new software is released the same time as a new apple product, said new software will cripple old devices. Ironic, huh? I knew that going in and still couldn't help myself from updating. Why do i suck so much and believe the :apple: hype?
 
6 days on 4.3. Is slower, drains battery 2+ times faster in the standby mode. It’s horrible.
iPad 4.3 is the same.
Flashed back my iPhone and iPad to 4.2.1 today, works good again. No more updates. With every next update my devices becomes only slower and choppy. Apple forces me to purchase new one every year? No way, I’ll get some htc next.

/sorry for my english/
 
My battery is absolutely fine.
No problems whatsoever.
i wonder what the op expects 7% drain. AND

Its a smart phone. Buy an old Nokia 2g brick phone that sends texts and does calls. then it will last forever. SIMPLES:eek::eek::eek::eek:
 
When you say your battery is dramatically worse than before, were (are) you jailbroken? I can not recognize the slightest change in battery live. My phone is factory unlocked, so I do not have to jailbreak to use it with any Carrier.

You think it'll be different with an HTC?? :rolleyes:

got one, nokia e52. Up to 20 days in standby :)

Simfree, no JB. Works fine on 4.2.1. After updating to 4.3 got battery drain and traffic in standby (Push, mail, etc. disabled).
Resetting settings, configuring as new with lost all apps data didn't help.

Yes, it's different. Owned 3 htc's. All of them works like new one after several firmware updates.
I'm just remembering my old iPhone 3G. Unusable with 4.0
 
Damn 4.3

I have iPhone 3GS which is now running 4.3.

I have not changed any settings since upgrading from 4.2.

My phone has been sat on my desk all morning, I have received 1 SMS and sent 1 SMS.

My phone was fully charged at 6:30am this morning. At 13:30 my battery percentage is at 53% after 7 hours. The battery is not lasting as long as it used to.

Battery life was usually at the 60-70% mark by about 5:00pm.

I HAVE NOT altered any settings since the upgrade, and dont see why i should turn off anything to maximise my battery life.

I do not buy a car to be told I cannot drive at night and use my headlights....

If you are selling a phone with location services etc, you should make the battery able to cope with these demands....

The phone is DEFINITELY draining the battery faster than is used to, so I will try the turn off ping setting tomorrow and see if there is any change to my battery life.
 
here is something i found on the apple forums, i downloaded the app and its true enough, there is a constant connection that shouldnt be there :confused: I signed out, then reset the phone (home &power button pressed), no more constant connection now. hope this helps some of you a little more. :

I start saying that disable data connection is not a solution.. so i spent all yesterday to find the cause of the problem!

As described by kolella disable store account appears at the moment as the only possible solution to disconnect the push.apple.com:5223 connection.

This connection is normal when you have push notifications active.

The problem is that, as said kolella, even if everything is disabled (push, app notifications, ping, game center...) there is still a service which constantly connects to push.apple.com:5223. Everyone of you can do a test with the free app "NETSTAT". This causes a continued connection to the 5223 port and wrong data ingoing and outgoing (you can check it in settings>general>usage>cellular network data if you reset the data before) and consequently the battery drain problem. In addition even if in standby you can see the time usage increases.

The only solution is to logout the store account (settings>store>exit) and the connection to push.apple.com:5223 disappears, the time usage doesn't increase in standby condition and data traffic stops.

There's something wrong with the appstore!, in 4.2.1 never had this problem! I'm sure and it's objective!

I too had an decreased battery life on my iPhone 3Gs. It would fall to about 50%by midday with light use.

So I connected to iTunes did a Restore to Factory settings and then let it restore all my data and apps. Now after similar use I am at 91% by early afternoon.

All my updates were done before by just allowing iTunes to update my phone, I have not done a restore before.

Worth a shot to try I guess. :)
 
A summary

I figured id post a summary of this thread and what ended up working for me.
Before i did this i was loosing about 40% of my battery in under an hour basically doing nothing.

Turn off Ping and itunes

Turn off home sharing

make sure even if mail fetch is off that in the advanced settings it is still set to manual.

Reset network settings

Log out of the apple store on your iphone.

I know that turning off ping did not help me. Either logging out of the apple store or turning mail to manual made my battery go back to the way it was. I am at an hour of standby and maybe about 5 sms and only have used 2% compared to something like 25% before.

hope this helps
 
OP why is this bothering you so much ?

How much data does this use

as much as I hate to post personal comments it does sound like this is more about your malignant obsessive thoughts vs an actual problem

This would explain this right?

Clearly there is a bug in iOS4.3 with push notifications.

Fix soon Apple, instead of making us do the work?

I think it would.
My battery life is amazing now. Had the phone unpluged for about 5 hours now and battery is at 89%. Thats with light usage app store signed out, ping disabled, have notifications turned on, bluetooth on and connected to car for 30mins, BUT, i do have 3G turned OFF! With the improved 3G retention in 4.3 it may be an additional factor and may need some extra testing.
 
I assume everyone with issues is reporting this through the official Apple feedback link right? Obviously they are not reading this forum.
 
Just to add my two cents. I upgraded to 4.3 the very first day it came out. Full upgrade including reboot. Almost immediately noticed alarmingly fast battery drain for the rest of the day. Started searching the 'net for clues and quickly implemented the 'ping' fix. Didn't work, still draining quickly.

Next day peeps over at the Apple forums were suggesting a hard (two button) reset. I did that which strangely enough led to a different state than I would expect. A status bar came up and it took many minutes before it came back. It was like the phone was finally completing the 4.3 upgrade.

The phone actually lost some changed settings since the upgrade. I.e. after 4.3 upgrade, I turned battery percentage on (to track battery life). After the hard reset, the battery percentage setting reverted to 'no display'. Anyways, after the hard reset, my battery life has returned to normal as far as I can tell. Just my experience.

Yeah, this is weird, I downloaded that NetStat app and it shows that my phone has a persistent connection to one of Apple's push servers even though I have all push disabled and off and I even disabled Ping like I suggested to others. I even logged out of the Apple Store and rebooted and it is still there.

Two of the IP addresses shown by the NetStat app are:

17.149.37.121 resolves to
"nwk-st-courier038-08.push.apple.com"
17.149.37.4 resolves to
"nwk-st-courier024-03.push.apple.com"

Both of these are Apple push servers. The first one was before I rebooted, the second one after I rebooted. The NetStat app shows that my iPhone communicated about 4 kb to each address.

What the HELL Apple? Why so pushy when I explicitly turned off all push notifications?
 
I updated to 4.3 on Sunday. iPhone 4, purchased at the beginning of December. Just gotta say that if anything my battery seems to last longer (just a sense, nothing concrete), it seems speedier opening apps etc and the home button is more responsive. For me this update worked out well, thought I should let you know of a success story!
 
One thing I've just noticed since getting that NetStat app, even with Push disabled in Email, fetch off, and all manual including that extra "Advanced" setting set to manual, it leaves open a Push connection, and an imaps connection on your cell or wi-fi... bug?

It clears it if you kill the Email app in multi-tasking, but it seems very odd to do that on a manual set email

BTW, I'm using a Gmail account set up as "Gmail" in email... a workaround is to set it up as an Exchange, you don't get any push connections this way when set to manual :)

Just adding another voice to the massive drains since 4.3. I just did a restore, but have gone from backup. Noticed phone was REALLY warm all day (prior to backup). Just finishing this up now.

Hey guys

iOS 4.3 is causing poor battery performance. Went to bed at 5am this morning and 6 hours later battery has dropped from 100 to 93%. No apps or we pages are running and it had a reboot since I restored the phone rather than just updated.

My phone was jail broken before but all this has been removed. Before battery would drain at 1% every 5mins when in wifi. Now it's more like every 2 mins with a bigger drain when on standby and not doing anything.

I would expect a jailbreak to give poor battery performance but not the new software without it.

Anyone else noticed it? Have I done something wrong?

I can't comment on iPhone (still on jailbroken 4.1), but I can definitely say I feel that my iPad 2 is draining faster than my iPad 1. I don't know if it's a product difference or an OS difference, but I think it's OS level. My reasoning for this is that the battery dies faster in normal usage when lots of little tasks are going on and in standby time; however, when I focus it to one task for a battery test (like watching a movie, 65% brightness, wifi and 3g on), it easily gets the claimed 10 hours, with slightly better results than the iPad one. This tells me the same battery power is there, it just isn't being managed as well for simple usage tasks like email and browsing the web. Assuming it is the OS, hopefully a patch is administered soon.
