HTC Universal, MBW-150 and smartWatchM

[Standa]

I use this great combination of software and hardware, but big problem is watch's short battery life.
I tried some Tomal's roms with radio 1.15.00 and 1.18.00, but battery life is still about 13 hours. I flashed old but good Jwrightcmps's WM5 1.90.96, but there is no possible to launch smartWatchM at all. I will try newest tmobile WM5 today. Does anybody know some good rom for this use?
I asked for advice in official smartWatchM thread, but nobody answered me. So I am trying it here...

Hm... nobody has Uni and BMW-150... So I will use this thread as notepad:)
My first experiences: (rom, radio, watch battery life)

tmobile 2.00.41 WWE, 1.17.00, under 1 day
Jwrightcmps WM5 1.90.96, 1.18.00, smartWatchM does not work at all
Tomal WM6.1 8.5, 1.18.00, under 1 day
Tomal WM6.1 8.5, 1.15.00, under 1 day

Hi Standa,

Sounds interesting. What exactly is a BWM-150, (I've never come across a smart-watch... what can it do?)

What are you trying to achieve? Perhaps if it's the watch battery life, is there any way to reduce an update with it - if continually on BT connection, can decrease battery, but then I understand it must continually have BT on so it can display caller name?

How does your watch get recharged? If I had a watch and it's battery run out before a couple of years or so, I'd be very unhappy... but what do you expect from this device?

Hi -Jonny-,
sorry, my mistake - it is MBW-150, not BMW-150 :).
Here is the hardware:

and here is the software:

A lot of people can use their watches for 3 - 6 days but I can use them for only 15 hours. So I am trying to figure out where the problem is. HTC Advantage users have solved this problem with the right roms and radios, so I am following their way :).
I don't know how old is my watch, but it is max. 1 year, not more. So I expect longer battery life. I know that five years old device could have almost dead battery, but it is not my case and I still hope problem is caused by software part.
