Lenovo Yoga 910-13IKB Full Charge Capacity is lower than Designed Capacity days after unboxing

Ok, so I bought my Yoga 910 (4k/i7/16gb/512ssd) just a few days ago and, besides the fan noise (which I am currently working on) as well as recently discovering the issue I am about to discuss, I absolutely LOVE this machine! It is a workhorse and the build quality is amazing. That's saying a lot coming from a previous Mac user...

 

Anyway, I was looking around today while trying to get the fan issue resolved and I noticed that the Full Charge Capacity (FCC) of the battery is only 75410mwh, while the actual Designed Capacity is meant to be 78000mwh. It is about a 4% performance decrease basically right out of the box, is that normal? I only ask because I originally bought the FHD/i7/8gb/256ssd version, before exchanging it for the upgraded unit due to liking it so much, and noticed that the FCC on the original one was actually 80102mwh, quite a bit higher than the designed capacity. Not sure if there is a setting preventing the PC to charge to the full amount or what? Maybe I just got a battery with lower ratings? Any help would be MUCH apppreciated!

Re: Lenovo Yoga 910-13IKB Full Charge Capacity is lower than Designed Capacity days after unboxing

Hello Dmrphy03

Thanks for using the Lenovo forums.


This could be related to a software on the unit, as some units have something installed that helps prolong the battery life on the unit.

I believe it is called Lenovo Energy Management, if you search for this in the option menu, it should allow you to change these settings.

 

Hope this helps, let us know how you get on.

Upon a quick search, it looks as if Lenovo Energy Manager was such a thing in Windows 7 and 8, but not in 10. I don't have anything like that on my PC. All I have are the factory Windows 10 battery/power settings, the Lenovo Settings app and an app called Battery X, which I downloaded from the Miscrosoft Store. All the apps do are monitor the battery,they don't allow me to reset it or calibrate it or anything. I noticed calibration used to be an option as well, but it doesn't show on mine to be one. Thanks for the input though.
