Voice volume fading on my Motorla V551 cell phone

Appears that you have a bad volume control.

1. Turn off your phone when it's not in use. If you're not using your Verizon Wireless Razr, then shut it off. Your battery will last much longer if you regularly do this.
2. Charge your phone less. If you charge your Razr nightly, then your cell phone battery won't last long. Try to charge your phone only a few times a week to extend the battery life.
3. Keep your Bluetooth turned off when you're not using it. Applications, like Bluetooth, are notorious for sucking the power from a cell phone battery.
4. Protect your Razr from extreme temperatures. Your cell phone battery lasts longer if kept at room temperature.
5. Discharge the Razr fully. Before you charge your phone, let it completely die. You can extend the life of the battery by regularly discharging and then fully charging it.
6. Leave the battery in the phone. Keep the Razr battery dry and free of dirt to prolong its life.

How old is the battery? It sounds like the battery has died and needs to be replaced. I suppose it is possible there may be corrosion on the connections that need cleaning. If it is new enough you should contact the manufacturer.

if you bought a new battery but it has made no difference so i think it may b something so you must repair yor mobile

please change your mobile battery!

first of all check your profile(volume)settings .If still your are having that problem then it should be a problem in speaker itself that is speaker may be damaged .its better to replace a new speaker.

It depends on how much talking your doing. The Slvr is known for its low talk-time battery power. My slvr would last about 3 to 4 days on a charge, unless i was talking on it a lot. sometimes i would be charging it every other day. So it really all depends on the talk-time. Invest in a car charger for sure.

Make sure that you are inserting the charger perfectly strait into the phone so that both metal connector snap into place, at work we have a data base of different phones (not the V551) but we have the V600/V300/V330 and all have known issues for not taking charge as people do not attach the charger correctly. If this isnt the problem next step would be to try another charger, if you have a friend with a Vxxx series phone all chargers are pretty much the same, if you have had the phone for less then 90 days most carriers will warranty you charger and sometimes the manufacturer will warranty it for 1 year. If its a problem with the phone then the carrier and manufacturer offer 1 year warranty. If there is a cingular store in your area you could also try going there to test your battery in another V551 to narrow down exactly were the problem is.

I've had similar problem, and found that if I jiggled the charger prong, that it can make a connection. Sometimes, the connection is dusty or just not hitting the receptors in your phone. Hope that helps.
