Agree... when battery heat up, battery life shorten a lot.

Eg. like i always watch mobile tv with my K750i, the battery life from full charge only allow not more than 2 hours of playing time.

Can't understand why all this helpful info isn't included in the basic inctrustions that come with these phones!

Posted by TeenInvader
One other thing which is just another thing.

Signal strength effect the battery especially when on a call. They say the phone needs more power to transmit if the signal is poor.

I know this sounds stupid, but..... K700`s batteries are li-ion 3.6v and k300`s are li-poly 3.6v.

What happens if i try k3 battery on a k7?

Will it long last or what?


---sorry if my english is bad, i do my best---

Posted by max_wedge
if the battery is the same shap then it's almost certainly compatible. But that is just a guess, no responsibility taken

Posted by tranced
I tried once and it works fine, but i donno if it wont damage my k700.

my T610 battery lasts for hours after low battery indication. is there any problem in my K500 battery?

6 times the memory capacity to keep powered up, higher resolution screen, More powerful processor to run. And that doesn't include use of camera, mp3 playing etc.

U need to charge for 12 hours as of brand new users and drain your battery if you have it for 3 months or so before charging. Or buy a new battery for emergency purposes.

i think this one goes out to Nickel Batt users...

and in the case of Lithium Batt, its different... its a low-maintenance battery.. no prep-ups, no need to drain before recharging.

Posted by max_wedge
exactly. The issue of memory affect and lithium battery immunity to it is covered to death in this thread It's worth a complete read, much research was done by me and others in ongoing battles to establish that indeed Lithium batteries DON'T suffer memory affect (many useful links to battery info too)

Posted by jack77777
it is better with li on batterys to not let them run out of power and charge them up before they run out , dont worry the li on batterys dont have the memory effect.

i let myn fully discharge weekly just to make sure the battery is being fully used.

Posted by BlacK Devil
could be faulty charger / bug in the phone or while charging u played with the plug-in and it came loose but u did'n notice ... try charging again

Posted by BobaFett
or let it flash with the same or newer fw, might be that solve the bug...

Posted by maseyboy
u might try finding someone else with the same phone and trying there charger, that will show u if its a charger problem or a phone.

It may be a good idea to know that when you get a new battery it is advisable to drain it first before charging it for the stated time. All new batteries have some charge on them (depending on how long they've been on the shelf in the store) so run them down so that the first charge is from completely empty.

Posted by max_wedge
it makes no difference if you do or not.

You can charge the battery as soon as you get it, or you can start using it straight away.

I have a W810, is it a lithium battery?

Posted by strizlow800
Yes, it is Li-Ion battery

Posted by easy2deal168
Battery also drains quickly if a lot of software installed is open.....


Posted by max_wedge
yup, or significant bluetooth useage, java, music with external speaker or talking.

Taking photos and listening to music with the headset is far less batt hungry than the above uses.

Posted by psychonymphe
Leaving the charger plugged in while the phone isnt is awful for the charger - ex who was an electrician always used to kill me..

Posted by dcbastable
In reply to max wedge; with reference to charging the battery straight from the box. Any good electrical engineer will tell you that it is best to drain the battery when the phone is still brand new. This is because the little bit of charge that is on it has normally been obtained from it only being charged for a short while (no more than about 15 minutes) in the factory prior to it being dispatched.

At times i feel worried..

I just got my cell 20 days back.. W810i...and my battery doesnt last a day..!!

I mean it doest gets discharged on its own.... But i am like some 7-8 hrs online in day..!! and the downloading and all drains the battery..!!

So sum ppl said that i shuld use it so much..it will damage my battery very early..!!

What do i do..??

Posted by BobaFett
7-8 hours online? thats a brilliant result. u shouldnt be worry

Posted by Washburn
@dipen01

you are to replace your battery after two years or less...

use it as much as you want...

... just don`t do abusive charging.

If possible, drain it out before charging...

Posted by dipen01
Ohk...

Will charge only when it drains down...

it was kinda worrying me

Posted by Washburn
I didn`say that you should charge it only when it drains out....

just try draining it out once in a while...

Why does sony ericsson uses Lithium Polymeer if they have to be replaced so quick?

The Lithium Polymeer battery of my T68i is now 4 years and 5 moths old and works almost like new.

I am using dual sim adapter in my new Sonyericsson K510i,I have observed that my battery is draining much faster now( about twice faster) . Anyone having same experiance? Any fix?
How does it affect battery life?

Posted by Sounderrr
I also keep it in mind, I sometimes just let it run fully empty and then recharge .. it works longer for me then

Hi, with my w300i i listen to music for about 2 hours a day and about thirty minutes out of those 2 hours im surfing with opera. I don't make many calls, i'd say just about 3 minutes in total throught out the day. I start my day at 7:30 am and the phone dies at about 8 pm. So my phone battery dies after 12 and half hours with only about 2 hours of heavy usage. Is something wrong with my battery? I recharge it every night. I would think my battery would at least be at about 25 percent by 9 pm.

Am I doing something wrong? Is discharging daily bad for the battery? Shouldn't I be getting a lot more life? I've only begun this routine about 2 weeks ago. Is it possible I already screwed my battery. Should I get a new one? Or is this just normal for a w300i, (Same battery as k800)

It's the half hour browsing the net that causes the excess power useage. I can tell you from K750 and K700 experience, this is entirely normal. Half an hour of internet SUCKS battery big time!

The walkman is not a huge issue, it uses relatively little power compared to any kind of wireless connectivity (gprs, bluetooth)

So overall, should my new Li-ion (bst-33) battery be fully drained and charged for 12 + hours afterwards about 2 or 3 times?

you can care for your battery by not overcharging it all the time...

no that only applies to nicad and nimh batts. Lithium batteries don't trickle charge - so even though it is plugged into the charger, if the battery is full the charger won't charge. So there is no chemical activity when the battery is full and plugged, and therfore no heat to cause wear and tear.

i have a one quick question..my p990 supports usb charging.i also attached the charger to the cradle so that i can just let my p990 sit in her throne and juice herself up.but when i turn my laptop on, the charging would be from the traditional charger and usb charging..is that bad?

Posted by aatuif
My phone has seven bars to indicate battery life. I have observed that once the seventh bar is down other bars die down quickly, except, of course, the last one.

e.g. After full charging, if the seventh bar dies after 1 hour talktime, then sixth dies after 40 minutes, fifth after 25 minutes .... the second after 5 minutes, and the last gives about 10 to 15 minutes talktime....
