1; on 3G on you tube for 60 mins i lose around 16%
2: on wi fi for same I lose 14%
exactly same on GB and ICS
3: overnight my battery does not budge
4: during the day (I don't take my note to work, have a company phone) battery discharges between 1 and 2%.
5; just after upgrading to ICS I received a video call for 7 minutes, battery went from 100% to 94%
6: screen on, little internet, for 60 mins loses about 5 to 6 %
I'm that sad person who tested these,
1: 16% equates to around 6 hours
2; 14% equates to around 7 hours, which for continuous connection to something like you tube, I thought was very good.
I think users are dwelling on battery usage to much, reading virtually every other post about battery use I was starting to get that way, but I've come back to reality,
Just enjoy a great phone.
