dosen't k750 use lithium polymer battery? or both are same?
Hey, you're right, I never even noticed lol. But after reading on the battery university site;
Li-polymer Is technically lithium-ion-polymer, a small variation of the li-ion battery. It's a different cell formation containing polymer to allow for slim batteries. But it still has all the same characteristics and performance of the classic lithium-ion battery.

Yo, Andaho, I meant backlight. Not flash.
When a key is pressed on the phone, the phone lights up. It's the duration of THAT light I am interested in extending. Anyway, is it possible?

Ahh sorry, I read it wrong. I've also noticed it being a little annoying while playing strategy games such as Ancient Empires where you watch the CPU player take his turn; the backlight turns off and you have to keep pressing a button all the time.
It appears there is no solution to the problem... maybe in the first firmware update they'll add an option.

With the R1J002 firmware the profile "In car" will leave your backlight on all time or until you manually lock your keypad. If you have on automatic lock, the backlight will go of when the keypad is locked.
I'm not sure if this is still the case for R1L002. I'm not sure if it was in the R1A002 firmware.

this maybe because the prorammers thought you might want to waste your battery as much as you can

I use the profile "In car" guess where? In the car
Guess what, I have a car charger in there
Having the backlight on in the car where power is no problem is in fact very comfortable. I can see the clock on the phone whitout having to touch the phone to light it up.
I don't wear a clock since I use the phones clock. I do have a clock in the car, but it's integrated with the car RDS radio, so I have to choose between RDS info or clock info.
So thanks to the programmers that actually do make helpfull feature

i've heard that recharge cycles of li-po batt. are low compared to li-on. after 300-400 charge cycles, they tend to lose their optimium power. is it true?

They have several paragraphs on the li-poly battery towards the bottom of this page
http://www.batteryuniversity.com/partone-5.htm
They mention a limitation of li-poly is "Lower energy density and decreased cycle count compared to lithium-ion."
They also say "what then is the difference between classic lithium-ion and lithium-ion-polymer? Although the characteristics and performance of the two systems are similar, the lithium-ion-polymer is unique in that solid electrolyte replaces the porous separator. The gelled electrolyte is simply added to enhance ion conductivity."
Everything in my "don't drain the battery" heading is correct to li-poly batteries, although you are correct, li-poly batteries have a "decreased cycle count compared to lithium-ion".
Before you ask me; I can't find the answer to - if a partial top-up charge would count as a cycle? If I was to guess, I'd assume not.
The bottom line with recent li-poly batteries in mobile phones is to not treat them as nickel batteries, e.g. don't deliberatley drain them before charging (apart from once every few months to keep the battery power meter accurate).

@andaho
Thanks for the great info.
i personally think a partial charge would not be considered as a cycle or 2-3 partial charges may be considered as a cycle. as lithium batteries don't have this memory effect, a full charge can only be considered as a comlete charging cycle.
anyways, the lesser charging cycles, we have to change our batteries more frequently.

I never personally have a phone longer than a year... free upgrade phone, then sell old one on ebay
