iPhone 3GS battery drained EACH morning ... ?

Alright, did some testing today:
Started with a 100% charged battery.
Use: 2h 47m
Stand-by: 4h 14m
Activities:
- 1 call
- 5 text messages
- a 30 minuten Nike+ workout with music
- taking some photos (max. 3 minutes)
All with WiFi off / Bluetooth off and a pretty dim screen.
Now my battery's 48% ... that's ridiculous, right?
Options:
a) there's a background app running that's eating away my battery life (I don't know how likely this is?)
b) my battery IS indeed seriously messed up.
a call to all long-time iPhone users out there ... what should I do?

How long was the call?
That battery % is good based on that usage (2 hours, 47 minutes).
So the question is, did you really use the phone for 2 hours and 47 minutes.
The call was 3 minutes. Just checked.
And if I had to put my money on it, I'd say I actually used the phone for about an hour and a half.
The key is here: Use: 2h 47m
How long was that phone call? My guess is "a". This happens from time to time. When it happens to me I just reboot and I am ok until it happens again.
Signal strength was pretty good (4 out of 5 bars) and I wasn't using 3G ... don't really know what EDGE is, though? (sorry haha)
3G is fastest
Edge is next fastest (E symbol)
GPRS is slowest (little circle symbol)
I dont have the 3GS, I have the original 3G and I notice exactly the same problems as you (during daytime the battery is fine, but dies very quickly over night)
IMO, its do to with not being on 3G, I only get GPRS at home, so wonder if it is constantly looking for a 3g signal even though it will never find it, causing the battery to drain quicker than normal
Be interested to hear a fix, for me though i just put it on charge over night
as someone else mentioned:
1. change the push settings to manual (if not, the phone keeps cycling to check msgs)
and 2. turn your location services off. no need for the gps to be checking your location if you don't need it.
I found this made a huge difference to my 3G battery time (still waiting for my 3Gs

Don't have a 3G subscription, but when I'm not using WiFi, I get that little circle symbol you speak of.
Does anyone know of an equivalent to Bossprefs in the jailbreaking community. A simple app that lets you toggle Wifi/bluetooth/3G/edge/etc ... on and off really quick, without having to scroll through layers of screens in the Settings?

I left location services ON ... maybe that's what causing my trouble?
Location services doesn't drain your battery just by being on. It will only drain your battery if you actually use an app that uses the GPS.
Before going to sleep reboot your phone. Sometimes an app doesn't close properly and keeps running, draining your battery. Rebooting makes sure everything is closed. If the battery still drains during the night just take it to an Apple Store.
Alright, I'll re-enable location services then and report back tomorrow morning ...
Thanks for the help so far, guys!
It cuts off ALL network protocols.
WIFI, Edge, 3G, etc.
No data will be received by the phone.
Base on your use and your descriptions and your lack of reply to my previous post. I know what most of your problem is and that is you need to understand and know how to use your iPhone.
1ST You need to know if you are in a 3G or Edge service area. If you are in a Edge or Lower service area ONLY then you need to turn OFF the 3G option...this will KILL your battery. Go to Settings, General, Network and it says right there in fine blue print "Using 3G loads data faster, BUT may decrease battery life" If you are in a non 3G service area, you will kill your battery while it is constantly trying to search for 3G service. Turn it OFF until you go to the big city and need it.
2ND If you have Safari Web pages open in Safari App...IT WILL continue to run in the background, refreshing and whatever else that page does. I told you to close all web pages until just the white blank page remains.
3RD There ARE poorly made apps out there that do not shut down properly when they are closed. The Google App used to do this to me and would drain my battery in less then 2 hours until I found out that this was the app doing it. You may have another bad app...thus the reason I told you to shut down your iPhone before you go to sleep...closes ALL apps...then turn it back on without activating any apps.
At this point note your Usage time and your Stand by time on a sheet of paper and go to bed. Then in the morning activate and compare the standby and usage time. This will ANSWER all of your questions. Do a battery test during the day while actively doing life things is not the way to test if you have a bad battery.
I tried to assist you and you did not even try...this is the last post I will make in trying to assist you and tell you how to do it....IT HAPPENED TO ME and this is how you figure it out.
Good LUCK

Sorry if it seems I just disregarded your previous post, but I simply haven't 'gone to bed' since my first post, so I couldn't have tried your suggestions yet ... I was planning on doing that tonight though!
I shut 3G down and closed all open Safari pages.
I'll note the times before I go to sleep and restart the iPhone down.
You'll hear from me in the morning!
Thanks a lot for your help
You should make the compromise of just plugging it in before bed every night, and then you wouldn't have to turn any of that other stuff off...
The downside is if you are in a call in EDGE you cannot switch to 3G. You have to start a call in 3G to be able to use data at the same time.
