Sir/Mam,
I charged my Laptop up to 99% And then after i used it for normal work 30 minutes, then it comes with 65% with remaining battery, and full battery back up is almost is only 100 minutes, so you tell me how the battery back up is for longer period of time, company tell 12 hrs back up, i spend 83000 only for best battery back up and heavy use, i doesn't satisfied about that laptop
