I always put my phone to charge over night so that I can have a full battery for my next day at work. When I check my phone in the morning the battery says its at full but when by lunch time at work my phone will be at half battery without be even using it. Maybe i have a defective battery? I know its not my charger because Ive tested it on my wifes Sensation 4G. Anyone mind giving me some advice on what I might be able to do here or ig they have experienced anything like this.
