Thanks to all of you guys i really appreciate it now back to work i have two options of the battery tweaks : 1-) use the ideal profile but change the upthreshold to 95 and change the samplerate to 300000 enable vdd1 and vdd2 (change to 1) set powersave_bias to 20 and change maxfreq to 600 or 750 (safer) and change ignore_nice_load to 0 2-) use default profile and enable vdd1 and vdd2 and change powersave_bias to 20 those are the best i found but i prefer option 1 but can some one confirm that if changing vfs cache to 100 will get a longer continues usage but shorter standby time?
