Why charge it every night? The specs are:
# Talk time Up to 360 min
# Standby time Up to 288 h
I'm on my third one and it is giving me just total HELL. First off I get maybe 5 or 10 minutes of talk time for every full charge not the "up to 360 minutes" as the specifications state. Standby time if I do not use my phone is about 5 hours or 300 minutes not even close to specifications. This was pretty much the same on my first two Gravity phones. My third phone is about the same. I did the let it day and fully charge thing three times. I even let it get to the red flashing bar before I charge it up. Funny that it takes just 30 minutes average to fully charge my phone from total dead battery same as the prior others that Tmobile swapped out. I had everything swapped out including battery and charger. It is just flat out ridiculous to say "Just charge it every night and you won't have any problems" Everyone has been having issues with the Gravity phones. I'm not one to piss and moan about anything but this phone is just total crap and a joke. I wish I would have never purchased this phone. Tmo said they will give me a new phone of my choice if this third phone does not work out. If they do not do as they say I'm going to break my contract and pay whatever and move to a different cell company just to get away from this piece of total garbage. As you can tell I'm so frustrated with the phone. I depend on my phone for personal as well as emergency issues. Why have a phone you can not depend on if it never has any power or dies in one call or less?
If you're only charging it for half an hour, there's your problem. Just because you see the indicator as full does NOT mean it is fully charged. Charge it overnight, then actually use it until the battery is dead and the phone powers itself off. That last bar lasts a LONG time! I know, that's been stated above but obviously it wasn't read.
I work in a T-Mobile store, and we sell LOTS of these phones. I see a tiny percentage come back with battery issues, and it's as simple as explaining to people that the battery indicator is not linear - each bar does not represent a specific amount of talk time.
It's like a car - you fill your tank, and the needle stays at full for a while even though you're driving around. Does this mean you're not using gas? Do you get mad when the needle moves progressively faster as you get closer to empty, then freak out at the car manufacturers? I know it's not exactly the same (the issue with the Gravity is actually the reverse) but you should get my point.
