Battery Life Charging Capacity on Thinkpad X1 Carbon 3rd Generation

This is my statistics from lenovo settings regarding my battery. I would be glad if I can get your opinion regarding whether this is normal or not. Whether it is going down too fast.

 

Remaining Capacity: 39.75 Wh

Full Charge Capacity: 42.19 Wh

Cycle Count: 30

Manufacturer Name: LGC

Manufacture Date: 8/19/2015

First Use Date: 9/18/2015

Design Capacity: 50.22 Wh

 

Do you think that my battery is degrading a bit too fast considering it has only seen light amount of charge cycles and it has only been one year? I am surprised that the full charge capacity is now only approximately 42.19/50.22 which is only 84% of total design capacity. Is this somewhat normal in terms of battery degredation? I have an old thinkpad T510 where according to its power manager it still has like 90% charge capacity of the designed. Maybe it is because in the old power manager it had the charge threshold and the new thinkpad x1 with windows 8/10 did not. Fortunately there was an update which allowed for Charging Threshold so that should help increase the battery longevity....but alas it came too late haha...

That does seem a bit fast. Below are the stats from a 2nd gen X1 Carbon with an older battery and higher cycle count.

 

That said, battery deterioration depends on many factors like temperature, recharging protocol, manufacturer, etc. It can vary from battery to battery. This is like how brake and tire wear can differ based on automobile driving habits.

 

As far as I know Lenovo considers a battery to be defective if the Full Charge Capacity becomes less than 80% of Design Capacity in the first year. Seeing as your battery is close to that threshold I'd contact Lenovo to see how flexible they are. Also ask if they've seen significant differences in premature battery wear between LGC and SMP batteries.

Re: Battery Life Charging Capacity on Thinkpad X1 Carbon 3rd Generation

Hey guys,

 

A quick question. So i Got my new battery installed and it shows near full design capacity. To those that posted above, can you tell me what power charge threshold settings you use? I understand that in the new lenovo power charge setting, it is not like the old ones where you can set the battery to charge once it falls below a certain setting like 60% and stop charging once it reaches say 80%. This new power setting only allows you to set it to stop charging once it reaches a certain limit.

Re: Battery Life Charging Capacity on Thinkpad X1 Carbon 3rd Generation

My system is normally on AC power. I set the maximum to 60% in order to provide some "UPS" in case of power outage while also maximizing battery life. It could probably go down to 50% or even 40%.

 

If you use your system on battery power a moderate amount then you might want to go to 80%.

 

If you're on battery power often and need the most possible usage on a charge, then consider 100%. The battery won't last as long, but that's the price you pay for portability.

Re: Battery Life Charging Capacity on Thinkpad X1 Carbon 3rd Generation

I do have similar problem. My machine is 7 months old and battery full capacity is around 86%. I have contacted Lenovo and thecnician suggested to use it for now and see major drop I should contact them again since I have a 3 years warranty but I am not sure in this case if I should wait till things get worse.

 

Any suggestion?
