Hi, I bought my T460s about four years ago and havenever had any issues until now.
Recently (within the past month), I have experienced 2 problems with the battery. First, the drainage on battery suddenly became about 1% per minute, when it used to take hours of high memory usage to drain most of a full battery. Second, below 40% charge, the laptop is liable to suddenly turn off without warning. I haven't changed how I used the computer, and the change in battery life happened basically overnight.
At this point I get about an hour's use out of my battery not really doing much with my computer before it gets into hard-shutoff territory under 40%. The built-in Windows 10 battery monitoring metrics don't tell me much since it only looks at apps by % usage, and I really doubt Chrome suddenly became capable of draining 60% of a battery in an hour compared to how much battery life I used to get with Chrome open.
What steps can I take to resolve this problem, or even just further identify the cause?

The battery could be dying and windows is not reading it correctly why it would suddenly shut down. Use windows search and type command prompt then run it as an administrator. In command prompt type powercfg /batteryreport and press enter. This command will create a battery report under C:\WINDOWS\system32\battery-report.html or, in Windows versions older than Windows 10, under C:\Users\[Username].
Open the file to view it. Temperature and life cycle based on the depth of discharge are main causes. You can post the report here.
