I bought a LOQ 15 a couple months ago and have been dissapointed at its performance unplugged. Regardless of the power settings I get minimal battery life and Lenovo service is so bad that I simply cannot get the issue addressed. Before you thing 'LOQ's will not have much battery life playing games", realise that I just went from 100% power to 'plug in computer - low battery' in 36 minutes using Google Chrome. You read that right 36 minutes! I've already exchanged batteries with no improvement. According to Lenovo this is 'normal'. If 36 minutes of non gaming use is acceptable, then buyers should really become away of this. Unfortunately Lenovo definitely will not share this type of information easily. Its essentially impossible to add a review to the Lenovo buying website even though I have an account. Their online website reviews are essentailly a scan.
