Guys, some how solved my problem and with random reboots but also with battery life.
well its a combination of basic physics and a basic little bit of thoughts

:D:D
So, one time i was try to empty the battery completely, so i leave till to work all the time doing anything,after that closed by itself i was waiting to be cold, then after the passing of 2 hours ,phone was cold again,i open it, and was showing a little bit battery more around 16% , i start sse it normally and was waiting to close bybit self, it closed

and-after was waiting to cold again, i turn it on it was around 5% , again the same, and after this i was waiting to be cold . After that get cold i plugged it to charge with out turn it on, some time later about more than an houri turn it on and left continue charging with anything closed to be exactly i set it on flight mode, when it gets in 68 percent i reboot it and after showed me 59% . So the charging continues and around 90% i rebooted again and this time battery stayed there that was. When finally get completely charged i closed it and waiting to ee cold.
well huge different, first of all battery didn't jump from 100 or 99 to 90 or 89, better endurance and most important, reboots stop finally. I have righr now ondemand max 902 mhz i receive mails reply skype sms calls and coming back home with more than + - 30% .
That's it from me, by the way, to my device doesn't exist any more reboots even if the phone is in smartassv2 with max cpu mhz 979, it just get huge temo,thing that's dangerous so i lower it.
