Thanks those kind of apps sound informative, but I'm not looking to get too scientific about it.. i'll leave that to r&d. I would dl them and participate if anyone wanted to try an experiment though.
But even if the percentages are estimates, they generally tell you how much is left after it's been used, no? I don't think they mean nothing. I guess you don't have a battery indicator on the upper corner of your screen then huh? I think I'd feel like I was playing russian roulette if I didn't have some sort of indicator lol
Here's how I see it, if someone's percentage reads much lower after the same amount of time and the unequal drop rate continues... then their phone is going to end up powering down much sooner. Kinda tells that their battery/phone is not performing as it should. It's been 5 hours since my last charge and I'm at 80% while sponge's battery was at 70% after 2 hrs... though it might not be a precise measurement, it'll tell him if somethings worth investigating. It doesn't have to be a poll on percentages, it could be how you suggested... but if he's still the minority in either of the results then he could very well have a problem with his specific battery/phone. Either way, if a poll is done, everyone that participates should be under equal circumstances as much as possible.... in a place of decent reception (i probably should have asked sponge that right off the bat), idle state, full charge, no battery tweaks, phone used for at least a week or two, same percentage reading addons, etc. I don't need to go around starting a poll cause I'm happy with my battery life, but someone who's willing to go into depth and set parameters might want to set it up. I think some sort of group testing would be beneficial for those that are questioning their TouchPros...
