Yes, battery going down 2x faster then on Bloy0 but device working 2x faster and smooth . I prefer to work more enjoyable than work longer on battery power. The phone is working a full day on RC4 and it satisfies me. If you give a little advice to reduce energy consumption is going to be great, but it will not be easy. I used Galaxy S and I remember that rapid roms = short work on the battery. Rom runs faster and smoother than Wildfire S, which I had the opportunity to test yesterday. I think a good solution would be to dispose of some unwanted programs that can then still accelerate, but it is great as is. Very Good Job!!! This allows RC4 regained faith in HTC Legend and not sell it so quickly, is well made and now thank to OGO2 finally has a great firmware.
