I know that there's a big thread about battery life, but no one has time these days to read 20 pages with 20 posts on it, with a lot of off-topics.

Well, has anybody tested wich one is better (battery life speaking)? Close applications and call it whenever you want it OR leave applications running on background, so you just click it to use.

I'm testing very briefly (because I can't use the cellphone always the same as it's my main cellphone) and it seems that leaving apps running is better.

By apps I mean the most used ones (conversations, phone...) not the heavier ones (browser).
