I've had my iPhone 4 now since around August, and I love it. I upgraded from the iPhone 3g, so I found it to be quite a bit faster and that the battery lasted a lot longer.
That last part is, until now. Recently, I've found that even though I fully charge my phone at night, it still will go dead by mid-afternoon. That's even worse than my iPhone 3g! Previously, it would last a couple of days.
I'm wondering if the problem might be with the recent software update; I was late installing it and didn't know if that could be the problem. I'm not doing anything different than I was before, so I have no idea what else could be the problem.
I'm truly hoping to find answers here!
Thanks in advance!

When was the last time you turned the iPhone off, meaning actually cycling the power on it? There may be an app that is hung up and draining your power. Also, I'd recommend that you close all of the apps running in the background also. This should help if there is something hung up and causing the power drain.

make sure bluetooth is off and let iphone adjust the screen brightness. also sync your apps in itunes this will make sure they shut down properly,if they do not it will run and drain your battery. also do a hard reset this will help also. try the sync first see if tha thelps. if not make a appointment with the Genius bar and have apple take a look at it.

The Genius Bar?
That's in the Apple store, right? Sadly, the closest one around is about 300-400 miles away.
But I've gotten some good tips here. I may have been leaving my Bluetooth on inadvertently; I know that can do it. I've changed a few things; we'll see how it works tomorrow.

don;t forget to look at the apps, email and other functions that do autoconnect for update, these will drain the battery also

I'm running the current iOS release.
I have wifi and bluetooth on allways.
By the end of the day, my battery is no lower than 60% if I use it quite a bit, over 80% if it's mostly just come along for the ride all day.
My guess is you've got something running in the background unintentionally.
Have you shut off (slide to power off) and then restarted the phone?

Here is what I have found. I recently changed to Netflix and use their app on the iPhone, If I do not fully quit it within the quicklaunch area, my battery will drain. It is almost as if they have some process running in the background as it thinks it needs to finish some task that never finishes. Apple does allow certain activitities to occurr in an app in the background, GPS, file downloads, and a few other things etc....
I cannot prove this specifically but ancedotely when netflix is completely stopped, my batter life is what it should be.

The best way is to do a restore and set up as new but if you value what info you have in some apps and don't want to loose the data, then do a restore from backup and this will most likely help. One relative of mine had a smiler issue and had him do a restore from back up and all has been good since then. One thing that is always good to do, when moving from one version of iphone to a newer one it is almost always best to set as new and not set from a previous back up as this will insure that the new one will be set correctly without any faults from a prior back up. I have so far tried the restore from backup as a first choice and the last choice was to restore and set as new. One needs to this as Apple will not do any exchange or anything else prior to doing the restore and set as new as the last step before exchanging. So in a sense one needs to the work before going there in order to save from making several trips.
