Boost Pro display question

[Shadowtao]

Just got one.
Is there any way to display battery percentage? It only now tells me when I need to replace the battery. Would be nice to have advance warning.

The top of the display shows bars for the battery (5 I believe ) so not percentage. When your down to 2 bars good idea to change if not sooner. Top right hand corner of screen
