try letting the battery completely die and recharge it. Do this 2 or 3 times. Sometimes "topping up" a partially charged battery puts a memory into the battery and it wont allow you to do full charge.. I let my Nokia get to its last legs before replacing the battery with a spare and then fully charge the other one. Both batteries are now at least 6 years old.. Yes , its an old phone...
Has the battery been fully discharged (used until it will not power up the item) very many times? This is very bad for Li/Po batteries. If the phone is less than 6-12 months old, I would contact my cell provider and ask for a replacement battery. In lieu of your provider replacing it, your only option will likely be to replace it yourself. Unlike the old-school Ni/Cad rechargeable batteries, Li/Po batteries lose their ability to hold a charge if they are drained fully too many times. Also a good tip with a new battery is to charge it longer than just until the battery power indicator is full (overnight is a good basic rule, but check your phone's user guide or google the specific battery model for recommended charge times) for the first few charges, and avoid letting it fully discharge. Try to get it on a charger with at least 1 or 2 bars left. This will increase the life of a cell phone battery dramatically.
the problem is from the battery. the battery is bad and needs to be replaced with a new one. so, go to a nearby motorolla outlet purchase a new battery, charge for an hour before putting ON the phone.. NOTE; do not switch on the phone until the battery is properly charged.
There are basically 3 types of chemicals currently being used for cell phone and laptop batteries. Ni-cad, Ni-mh and Li-ion. There is a fourth makineg its way in Li-ion polymer. A couple things are consistent for all types of batteries no matter what chemical is inside. You must initially give the battery a 12-14 hour charge on the home charger. (Don't use a cigarette adapter for the first charge. This conditions the battery and don't take it off the charger that first time even if the charging indicator says it's full after 3 hours. Also the manufacturer's also state to run it thru 3 charge cycles. What that mean's is that you fully charge and fully drain 3 times. 1 full charge + 1 full drain = 1 charge cycle. Here's where the way you charge the battery starts to differ.
Ni-cad: Mostly only on older devices, has a "memory" effect, should be drained before a full charge is put on it, should be removed after overnight charge or can be overcharged and burnt out.
Ni-mh: Still used for some devices, has slight memory effect but not enough to have to fully drain before the recharge, should not be consistently left on charger after full charge that can eventually burn out battery and shorten usage time.
Li-ion and Li-ion polymer: Used on a lot of newer devices, has no "memory" effect, should be recharged as often as possible, actually likes to be charged and draining it regularly can cause the usage time to be shortened, can NEVER be overcharged so whenever you're near a charger put it on there. Besides those benefits a li-ion battery is lighter and smaller but the chemical can hold more charge than Ni-cad and Ni-mh.
So the one reply to your question said to error on the side of draining the li-ion batteries. This is incorrect information. You want to charge the battery before it gets below a 20% charge. Also batteries will not go bad from accidentally doing the incorrect charging procedure here and there but normally follow the correct procedure. One last note try to use the home charger more often than the cigarette lighter charger for best long term results. Cigarette lighter chargers do not give a full charge (about 95%) which in the long run can damage any type of battery listed.
ok this can be numerous things lets start with slide the charger cable out gently see if at any time it starts charging as you do this. No 2 could be the battery getting week, and loosing a cell in it. No.3 this is a software glitch that the phone needs for the software to be reinstalled which will take a technician familiar with modding and software.
