Hello to all X1C owners.

I guess this is a topic that has been covered in the forums again and again.

However I thought it would be worth asking other X1C owners, that if they have replaced their battery, how are they looking to maximize the battery life of the new battery.

I found some stuff on the Lenovo Forums relating generically to LiPo batterys that its better to maybe fully charge and fully discharge, avoid small charges to maximize the battery life.

I know its a bit obsessive, but I would like to get as long a life as possible out of the X1C as I like using it.

I also found whilst changing the battery that it was only secured with one screw (apart from the holes in the battery that utilize the housing screws). Thet bottom two screws that the video I followed mentioned were not present. I am only the second owner of this laptop and I know for sure that the owner before me replaced the battery.

Thanks in advance.

To answer your LiPo question, this isnt 1992 and NiCd is the only battery. As long as when your battery hits 0%, get ur battery on the charger immediately. Otherwise, do whatever.

1) In Lenovo's Power Manager (for Win7 anyways), there is an "Optimize Battery Life Mode" where battery starts charging when below 46%, and stops charging when reaching 50%.

This was supposed to safe battery life, according to Lenovo.

2) For Windows 10, there is this newer "Lenovo Settings" found in Windows 10 Store that does the same thing:

I thought 40-80% was safe? I guess its 50-0%

I forgot to mention. Windows is not installed on my system, its Slackware Linux
The battery reported as LiP in the info from /proc/acpi/battery which I normally trust for battery state:
Could be the battery firmware lying or some software getting it wrong. As the last full capacity is slightly higher than the design capacity.

I suppose I could emulate the Lenovo / Windows battery manager with a bash script to monitor the last full capacity against the remaining capacity state variables when discharging and alert me to charge, or stop charging. However reading it, it seems the Windows 10 version allows the user to set the thresholds, so who knows what is actually best. More research needed I suppose.
Thanks for advice.
