Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 
The only use I see for this is if I get stranded in some remote location, so I could have more battery power...

It's explained in the help dialog. It allows QCPUFreq to use a more accurate temperature.

i use QCPUFreq up to 950 only to play psx emulator then i reduce to 600 and uncheck the overclocking after closing the emulator, i do that twice or three times/day..is that harmful ? i mean should i stay overclocking the whole day ?

I'd say it's better to use 600MHz when you don't need more. Leaving the CPU at 950MHz all the time won't do any good - it'll only drain your battery faster.

This is expected. SmartReflex is unstable and it also says so in the QCPUFreq help pages. Especially with excessive overclocking (>750MHz) SmartReflex might cause reboots. SmartReflex is only useful for saving battery life - if you are OC'ing to 1000MHz you obviously do not care about battery life too much :P

To all QCPUFreq users:
I would also kindly ask you people to test the current release in extras-testing. Since the old release in extras has some UI problems in PR 1.3 I would like to promote QCPUFreq 0.4.1 to extras and this is where I need your help: so please test it and place your vote. Thanks!

A feature request:
To have finer grain of chooses how SmartReflex is enabled.
Before there were vdd1 and vdd2 which can be enabled or disabled separately. Now I think there is even more optionswith PR1.3.

Someone may be able to enable SmartReflex for core but not for MCPU and someone other way around.

This is definietely interesting. However I still only see sr_vdd1_autocomp and sr_vdd2_autocomp - I guess I'll have to mount debugfs first. While this looks promising I believe that this is not part of the Fremantle kernel - I'll suspect this is part of Harmatton.

I'll look into it.

Now I have a reason to thank you properly. For once I forgot to take along a spare battery and I think this utility got me home with nicely without running out of juice. So, thank you!
