1)New Macbooks coming!...in late 2019
2)Unless OLED is going to give you a 2+ hour battery boost while actively using the laptop, stop with the battery advertising. I'm really sick of the non-stop "better battery life" claims that give 10 minutes here and 20 minutes there...and that's under strict conditions of throttling your CPU way down and hibernating your drive every 5 minutes and dimming the display after 1 minute, disabling wifi, etc. It's not just Apple with all these battery claims, HOWEVER, Apple seems to lead its Marketing with battery life and also thinness. Maybe if it was a little thicker (gasp!), Apple could plop in a slightly larger battery (adding a, gasp again!, 0.3 pounds of weight).
The computer world needs a giant leap in battery technology if the goal is to make laptops, on average, last 8+ hours of non-stop use (such as while at work) or 24+ hours while being used intermittently such as commuting or light travel.
I believe the battery focus is such a far-too-important feature for the vast majority of consumers...laptops are cool and hip because they're portable and functional. But when you really sit down and think about it (the 90% of consumers), how often are you going to need 6+ hours of battery life? A plane ride or a power outtage really. Otherwise, you're sitting at your desk/home plugged into the wall (for at least a little while). And if you want to surf on the couch for 6 hours, a full recharge is usually 3 hours or less.
Part of the reason the battery industry has not developed a 24+ hour battery for laptops is because the need has not been there. People charge their laptops while they sleep for 6+ hours. The laptops are charging at least a few hours while at work if not all day at work. Laptops charge at the hotel room while you have dinner and fun. Most commercial planes in the USA have power outlets in each seat. And again, laptops charge from completely empty to full capacity in under 3 hours.
