With only minimal set-up, this new UWP utility shows a wealth of power and battery data on live tile, on lockscreen and on Glance screen (if your device has this). Impressive. The only caveat is that the data shown is overwhelming in terms of stats and with no way (currently) to customise its output. Ah well. Still worth a look, if only because it's cool!

From the Store description:

This app can show battery charging level bar graph on lock screen and glance screen. The update period is 15 mins.

Quite a accomplishment to get this data inserted onto the Glance screen - more control though please, Mr Developer!

This is free in the Store for the next few days, so grab it quick and then play later.
