I reckon that by 2014, 15 hours of Battery life will be the norm

yeah old news but far out!
First: Intel Bay Trail-T with 11 hour video battery
Additional features in Bay Trail-T include lower power draw leading to a claimed 11 hour video playback battery life in Intel's reference platform, a new microarchitecture with full out-of-order execution (OoOE) support, DirectX 11 support under Windows, and new security features for the platform.

Now my current computer lasts around 5 hours on browsing and video playback probably 3.5 hours so of course my guess is that Intel's 11 hours is a bit optimistic yet improvements in other hardware/software fields will probably bring it near that range.

And with IGZO low power screens

and I got a feeling that Windows becoming a yearly update will also focus on energy efficiency so 2014 version will be more fine tuned than current Win 8

I think by 2014, 15 hour of internet/average use battery life will be the norm for laptops/tablets.

Of course I'm guessing but hey

motorolas already almost doing that and their phone isnt even thick. im not sure why other companies arent doing the same thang

99% of ultra books are focusing on being thin and the numbers I've seen for new Windows 8 ultrabooks has been around 4 hours which is horrible. I think it will be the rare high end product like a macbook Air or an Asus laptop that is doing over 10 hours in 2014.

Devices like the RAZR max or thinkpads with extended batteries sell well but don't dominate. There isn't a huge market for ultra battery life, even though the added cost and weight are often fairly insignificant.

This. People seem to want thinner and svelte devices more than they want battery life. If the battery life is 'good enough', as in, the device still sells, than the manufacturer won't make the device thicker to allow larger juice packs.

With cell phones moving to non-removable batteries, I definitely want to see Maxx sized batteries in them. The Droid DNA, for example, ~10mm thick and sporting a pitiful 2040mah nonremovable battery. The HD Maxx is 9mm thick and boasts a 3300mah battery. Despite reviews showing the DNA to have OK battery life, that 2040 battery is still pathetic.

even if batteries never improve, the circuity can a whole heck of a lot- and im sure we probably will see 15 hour battery life soon. maybe not 13 months from now, but within a decade probably..

Hours of video playback means nothing. Hardware accelerated codec ASIC that can do one thing is of course going to be very power efficient. The real test is dynamic use doing multiple daily tasks and random web browsing and gaming.

I tried to kill my DNA by looping h.264 Walking Dead 1080p episodes so I could do a complete drain/charge/calibrate cycle, and it ended up using like 4% per 45 minute episode. Naturally vendors are going to cling to the specs that make them look best.

Reporting battery light in terms of static video playback with an efficient dedicated codec ASIC on the SoC is blatant cheating.

Also this fascination with anorexic thin trendy fashionable devices and buying phones first and foremost for the dedicated purpose of showing off is unhealthy. Give me a brick with a 5000 mAh battery.

I already get that. Love my Prime dock.

Do think the median will get up pretty far, don't think it will be Intel then.

If you don't care about performance 15 hours is already available. Of course most people trade off the additional battery life for either performance or size depending on whether they need the performance or not. I think the industry will continue to target about 8 hours of average usage. Which also means I'll continue to drain low end devices in 3 hours because they are too slow so I make them batch up requests and they just drain so fast doing that.
