[BetterBatteryStats] Kocai:
@Tungstwenty

Well the custom kernel I'm using is really close to stock AOSP kernel with color control and a little bit of undervolting. If you want I'll flash the stock AOSP kernel and post the content.

In the meantime, can someone enlighten me on what is mipi_link? It seems that no matter what kernel I use, if I don't put my phone into airplane mode, I'll lose around 1%/hour overnight when idling.
