Power consumption is more with trisquel 5.5

the kernels from 10.10-11.10 have a problem with power consumption, with 10.10 it's hardly noticeable but the problem has increased over a couple new releases. However, Ubuntu 12.04 has a patched kernel that vastly improves power consumption, and I believe the next Trisquel should also include this patch. In the mean time I recommend just use 5.0 for better battery life. You could also try the Jupiter applet which will help with battery life.

If it's a kernel thing you can pick new versions here http://www.fsfla.org/~lxoliva/fsfla/linux-libre/releases/

You can try using the powertop command (from powertop package) to see what's using power. How well it works depends on your hardware.

Can you modify the brightness with software? If yes, then you could write a script that saves settings at shutdown and restores them at startup.

If the problem was recently fixed in the kernel (and I believe it was), you can choose to install its later versions on Trisquel 5.5 Brigantia. Thanks to this repository, this is very easy.

I just removed 5.5 and installed 5.0. Now problem is solved. I think i should wait for 6.0 LTS.

And it would be better if anybody suggest trisquel team to have a software for changing proxy in 6.0 LTS. 5.5 donot include it..
