The battery life normally is just fine. But there is a bug that causes the battery to die in less than 10 hours (maybe less than 6 hours) on full idle without any widgets whatsoever.

Currently it would seem that the bug is related to wifi connections, but my investigation on the matter is still a little in the way.

Anyway, my device first experienced the problem of the whole device being slightly warm to touch and battery draining very fast no matter the usage. Then I have experimented around trying to find the cause. Currently I have found out that at least normally, foreca weather, calendar, location and media player widgets do not cause excessive battery usage. Will report more once my experiments are finished.
