A friend bough an Orphan M16+ (android 1.5/1.6 version) on ebay and after a few issues her battery only charges to 50% and takes a very long time to charge. The seller has disappeared from ebay so she cannot return the device. She is using paypal dispute to get a partial refund but really wants to get the device fixed. Can anyone tell me what kind of battery the M16+ uses? and where I might be able to buy one? Or tell me where it would be best to ask? Thanks in advance.
