Default OTA keeps bugging my rooted G2!

So the new 4.4.2 Android is coming at me OTA pretty strong. Its been bugging me the last couple of days, even though I've been putting it off (I choose "later" when it asks me if I want to install it). I have been rooted a long time now -- will I lose root if I download and install this OTA? I'm on a verizon unlimited plan, running Android 4.2.2, software version VS98012B. I don't have TWRP installed -- I only have superuser v3.1.3 (46), titanium backup pro, busybox free, and Voodoo OTA RootKeeper 2.0.3. I originally used ioroot to root the device.

Can I update without loosing root? If so, what method?

[and how has people's battery life been holding up after the update? I've heard some negative stories...]
