Hello, I just got an i7/8GB/256GB SP3. The fan is loud when it gets hot under load, but I suspect that is expected because of the CPU. I have also noticed that I am getting an average of just above 4 hours of battery life per full charge. I sometimes have the device at 100% brightness, but for the most part it is 60-75%. I actually just exchanged the device for a new one due to the charge getting stuck at 99% and it read, "plugged in not charging". Anyhow, I use it for web development, watching TV shows and movies (both on the device and streaming) and just plain ol' web surfing. I was just wondering if all of you owners would be as so kind as to tell me what you are getting as far as battery life and what do you use your device for. I would surely appreciate it. Thank you in advance for your help and responses.
