Hi, I've read and seen many threads about battery life when it comes to light stuff such as light browsing.. turning down the brightness etc etc. I have my rMBP 15 inch and im curious how many hours other people get from their laptops when they do "normal" stuff. what settings u using and etc. Like.. stuff you would do if ur charger is plugged in. Examples: 1. When browsing with full brightness and like 5-8 tabs. 2. Watching movies. 3. Playing games. 4. Listening to Spotify when browsing.. And stuff like that.. I feel like i get about 2-3 hours when doing stuff like that.. What do you get?
