Root [International] Battery Life Has Nosedived

[nigsy]

The battery life on my phone has nose dived in the last 48hrs.
I've changed nothing on the phone, but I took it off charge at around 7am this morning and by 13:00 (now) I'm down to 5%.

No phone calls, a bit of facebook, probably less than 5 mins combined, and 10 mins tethered.
Running Omega 44.3.

Normally I get around 15 hours before I need to charge and then I' at around 30%.
Any good apps to monitor what's going on?

I use BetterBatteryStats (there's a free version on xda) plus Siyah kernel as option in Stweaks to report discrete stats to BBS. Sure there's a load of other apps that folk will recommend but once you understand how to use BBS and what it tells you it's very useful to catch rogue battery drains.

I think something has got 'caught' in the system, like syncing or something contacting a server and its draining the battery, as Android OS is using most of your power. This happens on my Nexus 7 quite a lot, usually a reboot sorts it out
