Ok, you must be one of those few fortunate to have actually found an indeed lasting-one as, after I've researched, it seemed that majority of those who did buy it weren't so impressed after all; to the extent that some referred to it as being even less powerful than factory-one (battery that came with phone)...guess one has just to take the risk and go for it hoping to find exact same stock as yours (I am saying this as, yet, people who bought it from same dealer, had still different response); worst case scenario is 10 quids rather flushed, which, compared to the desire of having a "normal" smart phone (as for lasting at least one-day) it might be a gamble still worthwhile taking...let people decide (at least they now know better); as for me I am gonna wait for my handset to come back from manufacturer's guarantee repair scheme as, indeed, I've evetually given-in and sent it back to them. Thanx for sharing
