Nope! And no way!!! Battery is like new, as I switch it on from time to time (every few weeks/months). Just did so and it had 14%, now (with this power level) I normally keep it on until battery flat, charge it, keep it on for a day and switch off. [meanwhile gloating over the cute 'DEVELOPER EDITION' writing over the screens. Version: 1.2011.15-7_PR_RM680] And it is kept inside a microfibre bag (sunglasses) in its box. So no dust particle to be seen outside, neither inside. Any more questions? ('I do take care of my beloved')
