Yes, I do. However I have to switch off my phone when not using it to get through a day, or use a second battery (which is fine for me). A night takes about 50% battery when it's on. Improvements are very much expected.
That would be a problem for those of us who would rather have a thick phone (I'm perfectly fine with 2 centimeters, no kidding) with great battery life (== early morning to late night at high load), rather than a credit card thin one that needs to be recharged too often. Might be a further development in which users can purchase a thicker rear cover with bigger or additional batter(y|ies) and snap them in place of the original one.
