After a long time of users asking, Valve has actually added an official Battery Charge Limit setting in the latest Steam Deck Beta update so you no longer need to use third-party tools.
When it charges up all the way, it stops charging and just does passthrough power instead. You can then see the battery % slowly drop over time, which is probably why you were seeing stuff like 95%
