I had these phone for less than 2 years and it is not charging properly, on the phone for about half an hour and it starts beeping

If you have them less than a month they are under warranty.

The optimus black phone should take 2-3 hours to fully charge. When you get a new phone, however, it is generally a good idea to let the battery completely die before you start charging it.

Over time, batteries hold less and less charge. Supposedly, by allowing the battery to completely die before charging it the first time, you improve the longevity of the battery.

If the cell phone battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% and graduallythe charge reduces until the battery won't charge up at all. OR The batteryshows a 100% charge but when the adapter is disconnected the battery drops offto zero capacity in a very short time. If the battery drops to an unacceptablecharge level then the battery needs to be replaced.

its just 3 things.
1; battery
2: charge regulator on the device.
3: power pack
one is bad.
so its not battery, now its #2 or #3

seen the regulator is toasted
very common
why not buy as used spark same device, and mix part to get good
or ditch it and upgrade,

Bluetooth headsets, like many portable devices can be charged on a USB port on a computer, which supply less than 1A, so either charger would be suitable.
Looking at the manual, a full charge should take two hours, so half an hour seems a little quick.
Perhaps it was part charged?
You could see if you can listen to music for six hours on a charge, and if so how long it takes to charge then.

A normal battery only last between 300- 400 charging cycles, If you have had the phone more than a year time to get a bew battery, if less than a year check with your cellular provider to see if you battery has a limited warranty

hand set no dail tone cant all out on the hand set due to no dail tone

Well it sounds like a combo of both. Definitly get the battery replaced again. The phone itself probably needs new software. take it your service provider's corp store to get the software updated.

I looked up the battery specs for your phone. They are 3 X 200mah= 600mah battery packs. They should last 8 hrs talk time with the headsets. This style of battery pack in my experience only last about 1 1/2years and sometimes longer and "sometimes" shorter...much shorter. I bet you never had problems when you first got them. Basicly this "battery design arrangment" goes back many years before newer battery technlogy was developed. But designers still insist on using them even today. They are cheap to make. ****Time to replace them with new ones.**** Make sure you follow the mfgs charging instructions: "After battery installation, place the handsets in their base unit or charger and allow to charge for 16 hours before use. You can keep the battery charged by returning the handsets to their base unit or charger after each use. When the battery is fully depleted, a recharge takes about 12 hours. Average talk time on a fully charged battery is about eight hours depending on environmental conditions, standby time is approximately four days." Good luck

use your warranty and replace the battery
