not sure how accurate iStat is (given that its just jumped 8% from simply unplugging and plugging the power adapter in) but iStat was telling me my battery was at 62% health for 70 cycles which IMO is ****. its so **** it cant possibly right can it? ill be honest i do use mine on the batt a fair bit but i used to get over 4 hours (general work, dim screen) and now its telling be less than 2 hours. the damn things less than a year old and the battery is already fubar'd... not my idea of good to be fair. what should i do? i do do the conditioning routine....the running it flat then leaving it in sleep to get flatter and then charging it. i dont do it monthly, but i do do it.
