What is the expected battery life of the Surface Pro 4?

[saintforlife]

Anybody know? Is the M processor model expected to have a better battery life than the i5 or i7?

I don't know, as it uses 4,5W TDP, same like the other 2... I believe it still has better energy consumption somehow...

9hrs (of video playback) which is about the same as the Pro 3... so I'd guess around 7-8hrs of battery life

i thought skylake would increase battery life or something. This is annoying. I want a tablet that can at least reach 12 hrs.

Well I'm currently getting an average of ~8hrs (Pro 3, i5) of battery life, but this is a collective mix of Office, Apps, internet (YouTube, Google scholar, etc.) But I feel your pain, its annoying that you can't get at least get a days worth of battery, it would have also been nice if they'd released a power cover with the Pro 4.

the new skylakes definitely use less power. Plus no fan. Plus no overheating, thus slowing down the processor.
Maybe 10-12?
Wonder what the differences will be between the i3 and i7 battery life

There is no i3 Surface Pro 4...

There is the Core M3, Core i5 and Core i7...

The Core M is without a fan, while I'm not sure whether or not the i5 and i7 models have a fan ( I'm more so leaning towards them having a fan)

They do have fans.

Also, here is the battery life info.

If you read the fine print it says this about which CPU they get the 9 hours battery life rating from and how they got it.

"2 Testing conducted by Microsoft in September 2015 using preproduction Intel? Core? i5, 256GB, 8 GB RAM device. Testing consisted of full battery discharge during video playback. All settings were default except: Wi-Fi was associated with a network. Battery life varies significantly with settings, usage, and other factors."

This leads me to believe that realistically if you are using it beyond light duty you'll probably get in the 6-7 hours range. Maybe 8 if you dim the screen.

I am sure it can probably pull a full 9 hours in light duty usage though.
