I have a HTC Wildfire 2 years. In permanent failure battery for more than 6 months, I hesitated a long time before changing the battery or phone. I opted for the cheapest solution. A small improvement since the battery keeps the day and I have to recharge every night. But I'm really disappointed because I uses neither internet nor the gps battery conservation in mind. In short, it is not the top, even for limited use on the phone and sms;
