I bought a replacement HTC battery as I read somewhere that there is a chance these are better quality than the one in the box. I also read somewhere that every now and again you should lett it run dead. I did this once last night. When I charged it over night, it said 100% as usual. I unplugged it and left the house. Checked again it was 91%. I plugged it in at work, got to 100% and disconnected it. It was still 100% and I used it until 88% Plugged it in again, it was 100%. Disconnected it and immediately it said 90%. These %'s are true even after a battery pull and I believe them to be accurate. Have I broken my battery? Is this due to the fact that the phone stops & starts charging to maintain charge? With the last charge I could see usage being the problem as I did use it a fair bit once it reached 100% before unplugging it, but the overnight one doesn't make sense. Any ideas anyone please?
