LG VX5400 cell phone power problem

My phone powers down on its own, even when fully charged. I have been having this problem for a few days. For awhile it was turning itself off almost instantly. Last night I recharged it and it stayed on for a couple of hours before I went to bed, but by the time I got up this morning it had turned itself off again. (It is still showing the battery as fully charged.)

    This happened to me too. I took it back to Verizon, they gave me a new 5400, and it started doing the same thing after a couple months.

    Same here. I bought mine in Feb 08. It's now Jan 08 and it's been doing this for maybe a month now.

LG neon battery dies within minutes!

The same thing happened to me you have to take it back to LG and tell them to replace your battery or buy it from Radioshack. At&T gives cheap batterys.

Secondly, you didn't even pose a question.  I can assume you meant to add 'WHY, LORD, IS THE HAPPENING TO ME, WHY!!?!", to which I say, "When phones get wet they get broke."

Stop procreating, please.

Phone will not turn on

If you haven't done it already, try unplugging it and removing the battery for 10 seconds and reinsert it, if that doesn't fix the problem there's not too much you can do about it anyway. With most cell phones, you can easily take the casing off but everything's integrated, so it's cheaper to buy a new phone than to try to fix a current one.

LG ENV2 shutting off

I just got mine a few weeks ago and it does the same exact thing (I didn't drop it, there is no water damage, I didn't understand the cause of it). I took it back to the Verizon store and I was told that the random shutting off like that is caused by having the phone outside being exposed to heat. He reset my phone back to factory settings and that did the trick for awhile (its hard for me to go to the pool and not have my phone exposed to the heat). There is no charge for them to reset the phone. Mine has started the random shutting off again back up

VX5400 turns itself off.

I had the same problem and brought the phone to a Verizonwireless store. They replaced it under warranty and did not give us much of a hassle. My guess is that it is a common problem. (On a side note, if you take the battery off the sticker shows a field called H/W Rev. The old phone was 1.0 and the new one is 1.1 which further suggests that they have made hardware changes to solve this problem.)
