Samsung B2100 problem,

[GrandeGuy]

I ran my phone down, like right down and now it flashes up up the model number intro and thats it, wont recognise charger (i think, symbol wont come up).
Any one had this problem? Have i ruined the battery running it down too far?
Any fixes?
Things i've tried . . .
Removing the batt for an hour,
Mildly heating the battery,
holding the on button for a long time,


Anyone help
I has no phone now

Oh and of course it's over 12months old.

Stick the battery in the freezer overnight (in an airtight container to prevent moisture!). Defrost thoroughly (keeping it in the airtight container to prevent condensation!). Hopefully this will effectively 'reset' it, allowing it to take charge again, if it does allow it to fully charge before using it.

Samsung provide a 24 month warranty btw just take it back to the place you bought it and they will send it to samsung

If its anything like a Nokia battery just plug it in and leave it! Mine did the same when I ran it flat and it took overnight to recharge it. Worked fine after that.

Depends on the battery chemistry, lithium batteries = dead if they fall below 3v

Sometimes leaving them to recharge for an extended period can help but newer phones won't Charge the battery if they detect a problem.

This means you have to bypass the phone and boost charge the battery on a bench with an external power supply.

You ideally want at least an Amp and a similar voltage to the batteries rated output. you are looking to charge it for about 20-30 seconds like this. Leave for a bit and do it again.

What you are doing is effectively forcing a knackered battery to charge, so be aware it can be dangerous. If you're not happy just obtain a replacement

Once you've done this cycle 4-5 times try it back in the phone to see if it now charges properly. If not you'll need to seek out a new battery.

I have done this hundreds if not thousands of times on all manor of small device batteries.

The last time was a couple of weeks back with a blackberry I was sending off to sell and the phone wouldn't charge as it had not been used for a year. I cut the plug off an old LG phone charger which supplied 5v at 1A and used that to boost it, which worked a treat

They have a great get out clause that say 6month warranty on batteries

it takes a bit of playing around with but you can recover them.
pull the battery, locate the + and - re-insert the battery while trapping 2 thin wires in with the + and - terminals.

you want them thin enough so that the other terminals, like the temp sensor and battery data terminals still connect.

get 2 fully charged rechargeable AA cells, or AAA cells to make 3 volts or a single lithium iron cell from out of a laptop battery(one thats 3 or 3.6 volts)

!!make sure you get the polarity correct.!!

add the battery in with the phone battery by connecting it to the 2 wires and then stick the phone on charge.

the external battery fools the phone to go into "charge" mode and then charges the batterys up. after a few minuets pull the external battery out the phone and that should of fixed your recharge problem.

infact think of doing this like jump starting a car.. its the total same thing.

i can confirm this works with both lithium polymer and lithium iron batterys.

also works for laptop batterys, however it is often the laptop battery's charge circuit that dies, hence why i have hundreds of 18650 cells from the batterys lying around.

I did your method and the batt actually reads 3.75vDC on my multimeter, (3.7dcv listed on the packaging)
Think im gonna have to send my phone away
I have a computer link cable for my camera, when i plug my camera in the lead indicator glows red for charging, but when i plug my phone in it flashes red and the phone goes on and off randomly,
Any ideas?

Hasn't gotten wet has it? Even in a pocket when you've been out in the rain or left in a car over night? Cycling on and off is usually a good indication of a soggy phone.

Gonna presume its a 3.7v battery and by the sounds of it is good so that 2 year samsung warrantee might come in handy,that is assuming its not wet otherwise they might not honour it.

No dampness i know off, Besides its a B2100 solid extreme, Its water proof, so if it has got wet inside they have them selves to blame

 

[PuntoHowTo]

The problem with so called water proof phones is once the water gets in, it often can't get out so can build up and not allow the phone to dry out, moving from warm to cold environments causes the water to condense on the metal parts such as the pins of all the chips and other electrical components, which leads to corrosion and shorts things out

 

[neeny09]

if it has gotten wet there are little stickers on the battery and in the phone that will have turned pink it has come into contact with water At O2 we were always told the 2 year warrenty covered everything except water damage
