Warning before battery runing dry

Dear Leikr team,
In order not to loose an exercice and get time to save it before the battery run dry, it coud be great to have a warning few minutes before the battery's death.
Vibration alert + message on the whole screen could help.
There is nothing more frustrating than to loose datas after a 4 hours + training.
Regards.
