i'm happy to say to you guys now i've been testing an N900 with all the battery tweaks including the new one and this is the fifth day and it is finally drained yesterday means 4 day long i was surprised when i saw that (really surprised) i told seker_94 about it before and looks like he is getting great results too so i will post it after 6 hours from now till i have a time to do that please be patient a log of what i did in these 4 days : day 1 : didn't use N900 a lot only for calling day2 : used a lot of browsing with some media playing day3 : used gps about 1 hour and used a bit of browsing with regular calls (about 10 - 15) day4 : i woke up and i saw the battery was about 25% browsed the web played some webos and finally it said to me to me battery low but what is surprising too is after it said battery low i just left n900 to stand by (only calls) and it took 5 hours to drain completely BOTTOM LINE: regular and normal use of N900 (browsing calling sms webos and media player) will stay from 2 - 4 days according to the use a very heavy use of N900 (hacking wifi and some pcs + using apt-get a lot + rebooting + spending to much time on games) will take about 1 - 2 days a complete standby hmm didn't test this yet but i think it will take from 4 -5 days
