In my country, all cell provider give free incoming. However they are making money on outgoing call.
Based on the fact given by you:
Lithium-ion (Li-ion) 500-1,000
Lithium-polymer (Li-Po) 300-500
I wonder why SE still prefer Li-Po instead of Li-ion. Any thought guys?

lithium batts really doesn't matter when and how you charge them. They don't suffer from memory affect, so you can charge them when they are almost empty, half full or almost full without creating memory affect.
Also lithium batts aren't trickle charged - that means when they are full the charger stops charging. So you can leave them on charge all night without reducing the lifecycle.
They also cut out at a certain low voltage, so you can't damage them by running them completely flat (older lithium batts could be damaged by running them completely flat).
Also they don't need to be deep cycled, so you don't need to run them flat then fully charge them every once in a while as you should do with NiMH and NiCAD batts.
You can basically do what you want with them

I notice different battery types with the same connections each storing
a different amount of energy
Typicaly I use a K750i using a BST-37 battery
I'min for a replace ment battery
could I use a BST-40 (P1i) battery in my K750i
I will probaly need to charge abit longer,
But I've got long nights
The BST-40 would add an other 10% to the life time
-Longer talking
-More MP3
-Longer without recharging
Is the layout identical ???
What are the risks ( for sure not supported but....)
Any reactions ???
An unbranded K750 that does not want to be updated ?? |

i am also wondering whe SE still prefers the li-poly type over li-ion if the latter has a longer cycle time.
also, will charging the li-poly battery when it is still almost full decrease it's cycle time the same way as when charging it when it's almost empty?
is it still true that when you completely discharge a li-poly battery often, you will actually decrease it's capacity to hold a charge? |

Hey some of you got it wrong about Li type batteries.
It is preferred to charge them before the battery runs flat. Read the Memory Effect section over here:

that link says nothing about li-po having memory affect. Check you facts.
re: using until flat, most modern lithium batteries don't allow the battery to run fully flat - battery electronics power down the battery, and therefore the phone, before it is completely empty (otherwise the low voltage will reduce the batteries life cycle). So you can't run the battery flat even if you want to.
re: over charging while full, in this case lithium battery charger stops charging automatically once the battery is full so it's also not possible to over-charge the battery (and therefore you do not reduce the battery lifecycle by leaving the battery on charge after it has fully charged)

here is what they say:
There is, however, no 'memory effect' in the Li-ion cell so that the life span of a Li-ion cell is not influenced even though the battery is discharged and recharged repeatedly at all times. On the contrary, you can get the effect of lengthening the life span of the battery if you use a little and recharge it again and over again. With this reason, more people prefer to the Li-ion cell and the demand is expanding even though its price is higher than that of the nickel battery.

Actually I meant using a little of the battery and not running flat. Sorry about that

what that link is saying if you read it properly, is that you can discharge the battery just a little bit then charge it up straight away (without waiting for it to discharge fully), and if you do it frequently it's good for the battery. If you did this with older style batteries you'd incurr the memory affect.
Therefore it's saying that lithium batteries DO NOT have a memmory affect, even if you regularly charge them without discharging fully first.
Suggest you study up on more than one poorly written page (which you have misread anyway) before you go telling us we are wrong

if the battery doesn't have electronics to prevent it from fully discharging, then it's a good idea not to run the battery flat. Lithium battery chemistry will degrade rapidly if it is allowed to run down to a very low voltage. But if the battery has electronics to turn the battery off before it reaches the critical low voltage level (ie: mobile phone batteries), then running the battery low won't reduce the life cycle.
So you can pretty much charge the battery whenever you need to without worrying too much about affecting the lifecycle of the battery.

The advantages of Li-poly over the Li-ion design include lower cost manufacturing and being more robust to physical damage (according to Wikipedia). Also, according to other sources I read some time ago, Li-poly batteries can be made smaller and lighter than Li-ion. The three underlined reasons are enough for any mobile phone manufacturer to choose Li-poly over Li-ion.
The notebook manufacturers will most likely choose Li-ion batteries, because of the longer cycle time and because a few tenths of grams in weight added to a laptop are of no concern.
