for a quad core/large screen phone ,, mine is good,,,
until there is a big break through in battery technology and we keep demanding more from our phones expect to have to plug in nightly,
also remember more so then any other phones out there,, droids are more like little computers
learn to shut things down
also like other poster said/ gps searching uses alot of juice
another thing i do where i work cell signal is terrible so i change to 2g service which allows me to still get calls and texts/ then when i want to surf i turn 3g/4g back on
(4g,,, im in Canada and it works)
