LG Optimus G Pro CM12 (5.0.2) Battery Drain (msm_hsic_host)



Hello All

I recently flashed the CM12 release of Lollipop on my rooted LG Optimus G Pro.
Everything works fine. However, the battery drain due to msm_hsic_host is confusing to say the least.
This is supposed to be mobile network related, and I have read forums where people say that this goes away when the mobile network is shut. However, for me, I am at home and only using WiFi. The mobile data is OFF.
I went to sleep for about 8 hours and I woke up to find msm_hsic_host had using about 80% and the phone was only in deep sleep for less than 1% of the time.

The phone NEVER goes into deep sleep. Deep sleep contribution is only about 1% ! Why is this happening?
Also, NOTE that the CPU Frequency stays at 384 MHz for 90% of the time! In the picture, it shows as 64% because it was taken about 2 mins after a reboot. What does this mean?

I have already hibernated Facebook, Skype, and another networking app. I am just lost. Why is the msm_hsic_host wakelock ON about 80% of the time.
