Someone else can correct me, but from what I've heard, limiting the charge threshold on devices is only helpful if the device is plugged in a majority of the time. A laptop that is primarily docked will benefit from limiting the threshold. Thinkpads (and others) have had this feature for a long time. With phones, whether it makes a difference, I'm not sure. Smartphones and batteries have become smarter to help with overcharging and extending life of the battery by slowing the charge rate when it gets to over 80% or so. I personally don't use thresholds my phone, it charges fast enough to make up for it.
