I just fully charged my Y2P and have the Energy Manager set to "Daily" and it is showing I have only 4:29 left.  This is about 1/2 the advertised time and pretty darned terrible for a Haswell CPU.

 

I have flashed the new Yellow Fix BIOS and new Energy Manager.

 

Am I doing something wrong here? 4 1/2 is really pretty pathetic.  Thanks in advance.

I haven't installed the new BIOS yet or the update to Energy Manager and I've been consistently getting between 4 and 5 hours. Good to know that at least the battery life isn't worse with the new update but yeah pretty disappointing battery life for an ultrabook with Haswell.

The battery life on the Yoga Pro is well below what they advertise. They should advertise 5 hours. I consistently get an average of 3.5 hours.

I am getting 7 hours at a power saving setting. Apple also claims 12 hours on their MacBook Air, but MacHeads are only getting 9 hours.

I have an i5, 8GB. I ran it in High Performance mode with 75% screen brightness from full battery till it completely died. I engaged in a mixture of activities--Web surfing, uinstalling programs, receiving remote access, video output to an external monitor, and several restarts--and the battery lasted right around 4 hours.

 

I'll try to repeat the test running it in a better energy saving mode to see how much of a difference that makes, but I wasn't very impressed (I guess i got used to my Surface RT getting like 12 hours at a time. Maybe ARM still has a place after all).


I ran the same test as above, this time in Lenovo Energy Manager's Stable Mode with about 70% screen brightness, engaging in a mixture of activities--Web surfing, Skyping, Netflix, etc--I got 6.5 hours from full battery to battery depleted.

 

So, those are the two extremes I tested:

High Performance mode with 75% screen brightness and typical usage = 4 hours

Low Performance mode with 70% screen brightness and typical usage = 6.5 hours.

 

Not very good compared to comparable products. And for those who keep trying to bring up the MacBook Air as a comparable product, it's not comparable. It doesn't have a touch screen. Comparison over, right there. Also, it's a boring product. If you're going to get a new computer, get a 2-in-1, touchscreen enabled Windows 8.1 PC. Way cheaper, yet way more versatile.

I think Intel's Smart Connect may be depleting the battery on the Y2P. This is what Intel Smart Connect does ..

I will disable and post more updates.

I uninstalled Intel SmartConnect as soon as I opened up my PC. I don't get the point of it.

 

I ran two battery tests after I installed the BIOS update and Energy manager update:

High Performance: 75% screen brightness, usage involved varied activities = 4 hours

Low Performance: 70% screen brightness, usage involved the same varied activities = 6.5 hours

 

Neither are very great for a Haswell PC, but the battery life was never reported to be that great. Still, I wish I had done battery tests before installing the updates so I could've compared them.

I can get 6-7 hours of battery life out of my Y2P post bios update.  I keep the screen brightness at 40%, but I adjust the processor to only be at maximum 80% when on battery.  I changed a few other settings in the advanced power settings as well that could help with battery performance.  Most of the time I am not doing anythign that is relying on heavy processor usage, so the 80% processor settting does not affect me much.  I set up a alternate profile to run with top settings if i need the processing power while on battery.  I avoid the Lenovo energy settings and let MS power settings do the work.  It has worked great for me.

 

PS- the 80% setting is about 1-2 hours difference in battery life for my machine.
