Has anyone used their N9 for the sole purpose of a wall clock? My N9 buttons are broken and I want to re-purpose my phone to be a Wall Clock. I am thinking I get one of these 13,000 mha battery packs and mount it in a picture frame hiding the battery pack.

I hope that the phone last 2 months worth running the clock 24/7 with this pack. Also does anyone recommend a good clock such such project?


Thanks,
