Thanks to the posts in this topic i read about battery issues,

I gave time to my battery to adjust itself, made 2/3 full charges and used the N9 till it stops by itself, then charged it again 100% when it was turned off, and for the first time today i experienced a normal/positive battery life, not that bad :


100% charged at 6am and arrived at 0% at 8pm this evening with a lot of stuff today (more than one hour loud music, a lot of web browsing all day at office , metro and lunch time, downloaded 15 videos from youtube around 50mo each, 10 sms, deleted and checked some pics i have around 1500 photos in my gallery to check)

The screen light was 60%, edge 2g more than wifi (enough to quickly update emails, twitter and facebook) no background internet connections...

Thats fine for me, i'm ok to charge every nights or end afternoons if i can use it quite often all day or a looonng night from restaurant 8pm to end of a nightclub 6ami dont wanna compete and limit myself to absolutely use it 2 days or more...

Think my battery is ok now
