Query: problematic

The battery would not hold a charge on the first phone that I ordered so I ordered a replacement. The replacement also had the same problem. The factory setting for the back light is set at one minute but remained on constantly, thus using up the battery in less than 8 hours. If the phone was used to make a call it went dead in a far shorter time. The idea of this product is a good one but this phone is not yet ready for consumer use. I cannot recommend another brand since Netgear SPH101 is the only one I've tried.
