Has anyone noticed increased battery drain after BIOS update dated 3-13-16?
I updated the BIOS and also reset the BIOS defaults and I am still seeing increased battery drain.

Ok guys I think this is a Power Management issue. My battery meter is erratic goes from 100% to 92% then 89% in about 30 minutes.
It never did this...any ideas? Thanks.

On 3/11/2016 there was also a updated Lenovo Battery Guage released. Try uninstalling your old version, reboot and then install the latest one.
Here is a link to the Battery Guage download.....

After you mentioned of a BIOS update being available I went ahead and updated my Yoga 900 last Tuesday. So far I haven't seen any ill effects on battery life. Did you try doing this soft reset of the BIOS? ....
1. Unplug the charger / adapter.
2. Press and hold the Power Button for 15 seconds.
3. Plug in the charger / adapter if needed and power up the system to see if the problem was resolved.

The fix that worked for me was something I did just a week ago. I restored the laptop using the lenovo button. It wiped all my apps and set it to factory default...and it worked!!! Battery life was restored!
I did notice that the BIOS was still the 3-13-16 version, so it may not have been that! I would say try and restore if you have you laptop backed up...Good Luck
