May be this is a cliche.I have my one year old battery very stable with custom karam's patch.But if i use it ,like browsing or what ever, the battery depletes as if it has been waiting for the opportunity.haha.But the speed patch is really good.Even though i care much about the battery, i could not really percieve a sea change what ever I do.As karam really pointed out, smart reflex is the life saver when the device is in idle mode.Thats it for now.Thank you karam.
