I'm seeing the the battery indicator stuck on the estimating message on a Dell XPS 9560 using Ubuntu 16.04.2 with 4.10.0-20-generic #22~16.04.1-Ubuntu SMP Thu Apr 20 17:43:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux.
The Dell XPS, as the Thinkpad of the OP, has a charge limiter to prolong the battery life in the years. It can be set on a range from 55 % to 100% of the battery capacity. upower reports the state as "charging" but the energy-rate is just 0,0114 W. I think that when the rate is so low, detecting a trickle charging it's more a fact than a guess.
