how can i make my battery last longer?!

i dunno, ive still taken 3g off and forced 2g and used task killers i seem to get 7hour battery. i've heard people get a day on a half on the review. I'm going to try switch off auto sync.
I don't really see the necesity in those atm. but I'll post with results.

Hi there!

I'm a newby with Samsung Fascinate two days old ( ). 1st day battery consumption was about 16 hours as I tried to figure out the settings, application, etc. 2nd day or today @ 12am or 4 hours after unplugging the charger, the battery status is 82%!..If with the same momentum of usage..I think tonight, i need to recharge this smartphone again.. (4 hours=20%, 20 hours=100%). As information, this what i'd done:

1)Install advanced Task Killer with 1/2 hour auto-kill
2)Use non-live wallpaper
3)Disable Auto-sync
4)Put phone on idle after 30s
5)Recharge battery once phone battery is drained off totally.
6)Screen Brightness (auto) as recommended or I should put it on minimum?

Any other suggestion or comment? I'm 3g user..

Thank You.

Having had the Samsung Fascinate i9000 since the 13th of July, I am very impressed with this smart phone.
The biggest fault I discovered is the very fast draining of the battery and the occasional screen freeze.
The battery needed to be removed on one occation.
Thurs 29th July for some reason after a 100% recharge, the phone charge lasted 5 hrs 50 minutes from a 100% charge.
Vary Bad. Wasn't able to connect to the internet in that period either.
Recharged to 100% and 12 hours later the battery only showed 40% remaining.
I rang Samsung yesterday and they thought the 5hr drain period was unacceptable, but the other discharge times were standard.

There advertised standby time is calculated when the phone is in flight mode and nothing is running.
He recommended a task killer app, and also an app called APNdroid, which kills all of your internet connections and sync.
Last night found and installed the apps.
I used the apps after a 100% full charge and today 14 hours later the battery showed 96% remaing. A big improvement.
Phone still works on normal phone mode allowing calls and text alarms etc.

To re-connect or sync just use the app button again,  WiFi needed a manual switch on.
I put a shortcuts for both apps on the idle screen one

When you are fully connected, remember Only use 2G not 3g unless really necessary.
3G uses a lot of battery power for some reason.
Have your screen settings to the lowest acceptable level and auto turn of between 30 to 60 seconds
or force turn off with the switch on/off button
The sleeping time for WiFi setting should be, to turn off when screen turns off. This is the better option.
Switching to never seemed to drain the battery continually.
GPS, switch this off unless really required.
Keep you bluetooth off at all times unless required. This is a big battery drainer

I trust this information is some help

Battery Test with everything disabled apart from the normal phone, SMS & MMS functions

The phone was used for the occasional calls

30th Jul 2010    1750   100% charge
31st Jul 2010    0950    97% Charge   After 16hrs
31st Jul 2010    1750    91% Charge   After 24hrs
1st Aug 2010     1145    80% Charge   After 40hrs
1st Aug 2010    1750    78% Charge   After 48hrs

All pretty good with the phone only connected

Sunday 01/08/2010 Clicked the short cut to re connect to the internet and nothing. Showed I was connected
but opening a web page I was informed there was no network connection.
After 90 minutes enough was enough. Battery drained to 65%
I decided to un-install the APNdroid app. I did remember to have the app stating that all was connected again
before the un-install. Reboot of the phone just to be 100% sure and all back to normal.
I can now only hope that the update amy fix some of the battery drainage problems otherwise stuck with it
until another working app can be found.

All I can say is Bugger !

+1 - Mind your connectivity. Being new to Android, I always wondered about the little 3G icon blinking in the corner even when I had all my apps set to manual sync! On a hunch I checked my bill online and I was indeed incurring connection charges! APN on/off took care of that and I'm now getting at least 2 days of heavy use.

ATK ftw! You can set it to auto kill every 30 min.

how do we set the auto kill on the atk????  thanks!

not sure how do I tell??? the sales guy downloaded it for me when I got the phones!
