iOS 4.3 battery drain

See this is why I don't like using Batt %
It makes you find faults in the phone.
ignorance is bliss!
but i wish I read this thread before updating to 4.3 yesterday...
at least my alarm clock works now
Just thought I'd update on my progress.
I did the disabled ping and a restore from backup on Saturday. Initially there was some improvement, but on Monday and Tuesday it was back to draining twice as fast.
I think its worth pointing out (again, as others have) the draining of the battery IS extremely noticeable. Before the update my battery could easily last 2 and a half days with my "average" use. Now it doesn't make it 12 hours! No change in any settings.
I took it into the Apple store and the guy did some diagnostics and said that the battery is fine but obviously there is dramatic difference in battery life. He offered me a replacement there and then, but suggest that I should continue for another week to 10 days so that they can get more diagnostic data. I said about this forum and that it may be a software issue and he agreed. So long story short if not happy by next week I can go in and replace my phone.
Since leaving there I have checked again to see if Ping is enabled and found that it was! Probably because of the backup had it on. So I disabled it again, also did a network setting reset. I then drained the battery (which didn't take long as it was into single figures) and then put on charge for 12 hours, overnight.
This morning I took it off charge at 7am, three and a half hours later I am at 95% and have used the phone for about 30 mins. This is much better! This time yesterday with roughly the same usage I was at 70%

Everyone really should get the NetStat app, there should be NO tcp connections at all if you have push etc disabled.
If you do have any push connections active, you need to check things like -
Ping disabled in restrictions
AppStore logged out in settings = this clears the buggy push connection
Clearing your sync queue for Calenders, Notes and Email (if using Gmail for example enable all three, then open each app for 10 seconds+ until the wheel is no longer spinning, then kill all 3 and enable which toggles you want, eg I just like email) = this should make your push and imap close properly after killing the email app (unfortunately leaving the email app open in multitasking keeps them open...)

Update
I have tried all the previous suggestions to increase my battery life.
I even restored as a new phone and found that that did not help either.
At the moment I have turned off ping and it seems to have helped increase battery life. Currently at 47% after 2hrs 6mins usage and 10hrs standby after charging to 100%.
Battery life is still not as good as it was pre 4.3 update, but is considerably better than before I turned off PING.

With turning off Ping some mail tweaks and resetting network connections I managed to get my battery to roughly what it was on 4.2, still seems worse to me.
I'm trying the sign out of App Store one now. I have a question with that, do I have to log back into it on my iPhone or can I leave it logged out and sign into it when I need to?
Thanks

Well for what it's worth, I did disable Ping as recommended by someone on the forum, and since my battery initially dropped out to zero, it charged fully. I don't know if it's the Ping disable or the battery memory kicking back in, but either way, my battery is back to normal.

Is there a way to prevent my iPhone signing into the appstore every time I sync?
NetStat is showing a whole ton of connections right after syncing, then eventually it signs in, then you have to sign back out and it makes new connections etc until it all goes quiet again.
This whole process uses like 250kb-300kb of data, which will add up if you sync every day and have a data limit :|

Having restricted PING, Reset Network Settings, AND signed-out of App Store I am getting good battery life.
Usage: 2 hours 2 minutes
Standby: 8 hours 5 minutes
Battery = 88%
Brightness 50
Notifications OFF
Push Mail Hourly
Used Location a few times
3GS 16GB - 4.3

I seem to have slightly worse battery life with 4.3 compared to 4.2.1.
I noticed that the usage timer will go up even while the phone is asleep. (went to bed last night, and when I woke up 7 hours later, the usage timer had gone up by 30 minutes...) So instead of battery draining ~2% like it usually does, it had drained by 7-8%.
We're gonna need a 4.3.1 I think. Maybe they fix the clock and alarm while they're at it.

I have my iP4 running on 4.3 and the battery is as solid as it ever was:
This is what I get with:
3G off
Blue Tooth off
Push off
Ping off
Wifi on
Location on
Brightness@60% with auto brightness on

I just did a clean update on my iphone 4 to 4.3 from 4.01. I turned off ping immediately. Im at 93% battery with 37 minutes of usage and 1 hour and 12 minutes standby.
this is definitely worse battery life than 4.01. I read the complaints beforehand, so i knew what i was getting into.
On 4.01, if i leave my phone overnight, 7 hours of sleep, 95% of the time, it wouldnt even drop one percent.
I'm interested to see how it will be now.
patiently awaiting an update from apple to fix whatever the hell is happening, along with a JB to make the update worth it.

Those numbers are normal. When you use your phone, the battery level goes down.

You're deluded mate, unless you was being sarcastic.
I doubt you actually used it for 15 hours, it's just the AppStore push connection bug making your usage creep up in standby.
I got my 3GS to "21 hours usage" and "2 days standby", doesn't mean the battery is great, since I didn't ACTUALLY use it for 21 hours...
That link fails to mention the actual cause, having your iPhone signed into the "Store" under settings.
Remember people, if you have mail set to manual, push off, and store signed out, NetStat should say "No TCP Connections" when you open it up or leave it open for a few minutes if you was just doing something online or just signed out of the store (signing out seems to take ages sometimes)
"Ping is a service where it pings a server via wifi or 3G every few minutes for new emails and etc"
Good to see you researched well for your blog post.
tethering
Have you all turned tethering off? In my case it fully reversed the symptoms of batt drain. By default wifi tethering was enable in 4.3. This could most likely be your source of frustration??

I am pretty sure we'd know it's enabled considering the only way to enable it is to pay more $$.
