LG VX9700 BATTERY DIES AFTER ABOUT 5 MIN OF TALKING. THE PHONE TURNS OFF. WHEN I TURN IT BACK ON IT HAS 3 BATTERY BARS SHOWING WITHOUT CHARGING IT. IF I CHARGE IT. IT WILL SAY IT IS FULLY CHARGED IN ABOUT A MINUTE. IT IS ALMOST 2 YEARS OLD. I PURCHASED A NEW BATTERY, BUT I DONT THINK IT IS REALLY A NEW BATTERY BECAUSE IT DOES THE SAME THING. IS THERE A WAY TO TEST THE BATTERY OR PHONE?

my phone is 1 week old and it does the same thing

SOURCE: I just recieved my LG Dare 1 day ago and since I

since you bought a new mobile phone,you need to boost a battery for charging more hours first,and people get around 4 hours of talk time. You should empty out the battery fully and recharge it fully, again. Good luck.
i have read the reviews oof DARe.so no worried and if you have weak singal stregnth in your area you might loose you battery power quickly anyway thats not your issue.

I took out the battery on a lg verizon phone oops put it back in now black nothing ?? There must be some sort of way to replace the battery that reinitializes it any help

SOURCE: how do i resolve the error: use genuine battery. power off

A temporary fix to the problem is to put the battery in the freezer for a minute and then put it back in the phone and it will turn on just fine! I had an LGVX8700 and it just randomly started happening one day and my fiance told me to try doing that so i did and sure enough it worked. I had to go to verizon at one point to get a new phone because the one i had got damaged and the tech there used the same battery in my phone for the new one and he thought i was crazy when i told him to put the battery in the freezer but he was in for a surprise when he did what i told him and my phone turned on. It's annoying because you have to do that everytime your phone shuts off but i always made sure i plugged it into the charger before it went completely dead.

My renoir has just developed this issue.

I have tried 2 batteries, tried re-flashing the firmware (even tried a custom firmware) and nothing.

I am buying another battery to see if i were unlucky with the battery I bought.

This does not appear to be an uncommon issue as I have found several threads online regarding this. No definitive answer as yet.
