SOT on CM11 and CM12

[metalron]

I'm coming from the ever so lovely and old Motorola Razr Maxx, the first big battery so at the good days on Jelly bean I was getting about 8 hours SOT. How's it doing now with CM11 and CM12 for the GSM Razr HD? I find this phone going cheap brand new and thinking its a good buy considering CM support is still official. Are the stable builds as stable as stock roms? love the new Turbo but too pricey

Thanks for any inputs.
