I will have to say switching to CyanogenMod 10.1.3 stable is the best thing I have ever done for my GNex. It getting so slow on JBS Encore that I could hardly even use it. My battery was about dead in 5-6 hours. CyanogenMod has now put new life into my GNex. It is fast...really fast and after 12 hours of use I still have 70% battery...that is after it downloaded and installed apps and updated them today after I flashed the ROM last night. This will hold me over until I dive into a new phone..probably the Note 3 I am happy finally with my GNex performance.
