When the battery level reaches around 20 per cent, the BB automatically turns itself off. is it possible to change that level? I can't find it anywhere in Options.

Thanks

No. Don't let your battery get that low. It's bad for the battery.

It's bad for the battery? I've never heard that before - could you provide more info? Thanks.

And check any authoritative source for information on Li-Ion batteries,:
How to prolong lithium-based batteries

Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.

always charge your battery as often as possible
