How to Maximize Battery on Any HTC Phone

HTC has released a known bug on how to double your battery life by changing your charging routine. The different routine is as follows: 1. Charge for 8 hours or until fully charged. 2. Unplug and turn off and plug back in and charge while off. 3. Unplug and turn on for 3 minutes. 4. Turn off again and plug in and charge for another hour. 5. Turn on. After doing all this it should maximize battery life. I tried it myself and it did significantly increase the battery life. What concerns me is why would HTC program the phone to use the battery to its full extent. Instead people have to waste at minimum 3 hours to get the most out of their battery. Is it worth it? Now that I think about it if I have the time it is worth it instead of buying an extended battery. But it does pose the question if android will somehow use the software to fix this problem/bug for this phone so its features can be used without fear of the battery dying.
