Battery life hack for HTC HD7

After a lot of playing with T-Mobile US HD2 WP7 i found one interesting thing:

If You start camera with green button and then switch to video mode there, wait for autofocus and after that just simple go out to main screen by pressing windows(middle) or back button then stanby current drops to 5-6 ma from regular 40-42 ma. (Switching to video is important - if not switched no results found)
It stays 5-6 ma on standby until next reboot. If You reboot and don't do this camera play current is 40-42 ma. But if i start camera -> switch to video -> out - current 5-6 ma.
After hack applied I used phone in different ways - talk internet email - standby still low 5-6 ma. I gave it 12 hours try - lost only about 12-13 % of charge. Checked battery outside of phone with load - real lose of charge was about same as Battery tool shows. Will continue to test longer but can expect at least few days with some usage of phone.
Did the same trick with my friend's phone - same results. It looks like really a bug some where.
Please report your results and HD2 type.
Was on XBmod 1.04, 12 radio, location on, data on, bluetooth on, xbox off, wifi off.
If this problem really exist it will be found in all ROMs.
P.S. Tested phone before with most others ROMs - found this one is the best, thanks for this ROM.
Hope this will be fixed permanently in NODO.
