turning off 3g and just using gsm would greatly extend your battery life. i have a w850i and p990i, if am not using 3g for internet browsing, i just turn off the 3g setting and my w850i would last for about 4 days from 2 (with 3g on) and my p990i would last me about a week from 3days (with 3g on). for p990i disabling the wlan if you are not using wifi would also help extend battery life.

Good information. Cool!

I'm thinking of getting a second battery after reading this this thread.

Good information, very important as well. My P800 had the same battery for 4 years and it became so swollen that the back cover did not fit properly. Very lucky that it did not explode! You should just check the battery to see that it is the normal shape once in a while.

1 question.
Is it ok to charge the battery even whn its nt tht low?lets say around 50-70%
Posted by VelcroMan
Thanks for the info!
Back when i had a Sony Ericsson T630 i managed to "burn" the battery. So i had to buy a new battery. Not so cheap... :/

perfectly safe. In the old days with nicad and early nimh batteries, they suffered memory affect if frequently charged up without running them flat first. Current mobiles use Lithium Polymer batteries - Lithium (li-po) don't suffer memory affect, so you can charge them whenever you like without causing memory affect.

Caring for your battery is very much important. From my motorolla phone manual it says that you can not overcharge your phone. If it is like this, when does the concept of charging a new batery for extended hours come into play. One other thing are these new fake batries that have floded the market. How do we cater for them. You can give them all the attention and care, but they will not respond positively for dn extended period of time. What then can we do with that?
the concept of long charging for a new battery IMHO is obsolete due to newer phones having smarter chargers to prevent overcharging, anyway most batteries are li-po/li-ion nowadays. Older ni-cad etc. batteries needed conditioning with long first charges/discharges.
As with cheap fake batteries, skip them completely. It's like buying a fake rolex, looks good, looks real but in the end it just breaks down and surface finish fades too fast and rusts
plus, fake batteries are more likely to leak and cannot hold charge well. Pamper your phone with REAL batteries!

Also, go for official batteries. Sometimes, the battery level is not read properly by the phone so it always stays at 10% even when full leading to over-charging etc. Had this problem with my Pxxx phones.

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?

my k810i for the 1st time i charge it for 8hours... the shop seller tell me to do that...then for normal i need to charge it full every day... because i using my phone hearing song for few hr during working...
i charge full use 1hr something.... my step got anything wrong that will short my batteries life?
Posted by max_wedge
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 ???

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:
http://www.powercellkorea.com[....]mode=viewList&category=&page=2
Posted by max_wedge
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.

You are both welcome.
Expect a big step forward in the field as soon as Stanford ends it's tests (Stanford researchers have found a way to use silicon nanowires in the battery's anode to store 10 times the amount of electricity the existing lithium-ion batteries can store). TEN times! Imagine recharging your phone once a month...
The good news is that the technology is now being tested for life cycle time (they expect at least 1000 charging cycles). The even better news is that if a similar revolutionary development is done for the battery's cathode, the storage capacity could be increased even further. There is a (somehow) bad news too: we'll have to wait around 4 years for the first commercially available silicon nanowires batteries. My personal opinion is that the approaching petrol crisis will speed up the process (such batteries will finally make the electric cars worth buying).
Look for "nanowire battery" on Google if you wish to read more.

noob question....
i wanted to buy a spare battery for k810i - bst-33 - R2a 950mAh, but unfortunately i cant find a battery with the same type...
the available is only for k800 - bst-33 r1a... my question is... can i use k800 battery - bst-33 r1a 900mAh to my k810i?
cause i happen to have a batter bst-33 r2b but it drain fast. it last for 3-5 hours...

strange that you have a 950mah BST-33 as I always thought it was 900mah. Indeed here's the product page for this battery showing 900mah
anyway, you will have no issue using either battery in your k810

I don't think it's genuine?

ya you may correct. but as i know if you charge your battery in correct way , you may get best results

BST33 are both 900 (earlier bat) and 950mah (later models..)

Does anyone know if it matters if you fully charge the battery before the first use?
IE: Start using it with the factory charge, before a full charge?
Posted by max_wedge
it's fine. Won't hurt the battery. I've done this with every phone I've owned. I've never had to replace a battery.
The battery won't charge to it's full capacity until after the first couple of charges.
