dun think so... same cable.. same connector...same power output...

In terms of affecting the battery life, I would say no.

Ok diff charging with dock and charging with normal adapter??

No difference...
The only difference is where you connect the power source (PC or from wall adapter)

Hmmm using 3G and wifi really fast drain the battery le.

How about the Noise ?
like PC CPU, same Walt but price different very big

try to decrease the brightness ... i saw some people with maximun setting ...

today i tested by turnin off 3g and wifi. brightness at 1/2. using iphone4 maxis.

usage : 23mins
standby : 8hrs 0mins
batt : 100%

very very happy haha.. super battery life. but once one 3g and play game. by 3/4 day, redi 20%.

p/s fone is barred. so no data activity. mayb dats y batt is stil 100%.

Brightness already half oh. As per normal I never changed the brightness. Seems standby life is really good but when use sure use a lot hmmm. I got a car charger last time for playstation portable using USB cable de. But when I tried using it with my iPhone USB cable it doesn't charge one.

half is still a lot ... i use 1/4 only ... and off those location services, push notification ...

Using 3Gs and usually I off 3G and Edata, only on when I need to surf internet. The batt can last longer. Brightness I put like 40% cause with privacy screen protector as well.

for ip4... double click home button for multitasking... and delete the running apps can save the battery life a bit...

Anybody encounter battery drain faster if using it just awhile?normally have to charge everyday??any solution??

my current flat out rate iphone 4 usage

heavy wifi. heavy gaming. heavy sms call - wont last 24 hour
heavy gaming. moderate wifi. moderate sms call. - a day
moderate wifi. moderate gaming. moderate sms call - almost 3 day

somehow i always fail to test totally withot wifi or game lol. i mean who can? not me

download ipowersaver, & it's free.

are those icons in the multitasking mean theyre running or simply recent usage? i mean there always alot! i doubt ALL of em are running.

It's Apps running in background = eating memory = eating battery.

Good practice would be to clear them daily before you go to sleep.

If i remember correctly the state of the apps is saved and then closed. it isn't running in the background continuously. Of course there are some which does ie. GPS apps... music apps. etc.

Anyways.. with wifi and 3g on almost the whole day. I'm getting 1 day usage. i hit 20% around 5.30pm d... is this normaL??

My i4 lasted 2 days + yesterday with usage of 4 hours +
Today switched on 3G non stop and lasted only 24 hours with quite some surfing.

Oh and my apps dont run in the background. I've disabled multitasking.

Good point. When I monitor my Apps using FreeMemory it won't display all Apps on my multitask bar. It could be just Apps with multitask capabilities enabled.
