My N9 has started having problems with massive power drain. Something like ~250mA average idle

Running powertop shows that twl4030_madc is causing like 80% wake ups in a 10 second period. I quick google shows that twl4030 is
The TWL4030 is the optimized all-in-one audio and power manager to a host of OMAP processors
Has anyone seen this before and got any ideas? I really don't want to reflash (yet) but obviously will do as a last resort.

I haven't installed any new software recently and am beginning to panic that it may be some sort of hardware issue...

What applications are getting the most CPU time?

Well if I run top, the only things using over 1% CPU are

/usr/bin/sysuid
/usr/bin/dbus-daemon
top
everything else is like < 0.9% CPU

Phone appears to have calmed down a bit, maybe it was just having a made 5 mins...

But still twl4030 is at top

Wakeups-from-idle in 10 seconds: 31126

Top causes for wakeups:
22.9% (30636) <interrupt> : twl4030_madc
0.1% ( 97) <interrupt> : mmc1
0.1% ( 78) <interrupt> : gp timer
0.1% ( 67) <interrupt> : prcm
0.0% ( 58) <interrupt> : DMA
0.0% ( 40) <interrupt> : twl4030_pwrbutton
0.0% ( 40) <kernel core> : hrtimer_start_range_ns (tick_sched_timer)
0.0% ( 14) <interrupt> : wl1271
0.0% ( 13) <kernel core> : hrtimer_start (tick_sched_timer)
0.0% ( 12) phy0 : wl1271_irq_work (delayed_work_timer_fn)
0.0% ( 12) phy0 : mmc_host_lazy_disable (delayed_work_timer_fn)
0.0% ( 10) java : hrtimer_start_range_ns (hrtimer_wakeup)
0.0% ( 6) <interrupt> : twl4030_usb
0.0% ( 6) skyhost : hrtimer_start_range_ns (hrtimer_wakeup)
0.0% ( 6) messageserver : hrtimer_start_range_ns (hrtimer_wakeup)
0.0% ( 2) <interrupt> : i2c_omap
0.0% ( 2) top : hrtimer_start_range_ns (hrtimer_wakeup)
0.0% ( 1) <interrupt> : rtc0
In last few hours idle consumption has dropped from 233ma to 81ma (and still falling at the moment ) maybe I panicked too much, I will monitor over next few days
