Reminds me of the time remaining to copy file(s). It stays on one time like 1 minute remaining for a long time and then goes away when it completes the copy.
Got a tip for us?

macOS Sierra 10.12.2 Removes 'Time Remaining' Battery Life Indicator

1. They always sell it as "up to" x hours of battery life. You're not guaranteed the number they say.
2. From the sounds of it it appears that whatever they had been using to calculate time remaining on the battery couldn't keep up with the processes in the computer, especially if the load is constantly changing.
Really, so all those supposedly mighty brains at Apple couldn't design an accurate estimation algorithm on a closed system? Or maybe the management just decided that being customer centric doesn't apply any more and instead will stick to their new strategy of "blame the customer" or "B/S our way to a reason for removing functionality and convenience"?
Surely Apple could create an 'time left' estimator algorithm based on the user's typical usage. Any prediction would have an error, but over time this should go down.
Meanwhile Google implements deep learning and aggregates use patterns across all its userbase and comes up with an estimate based on your historical patterns, so that it's good down to the second.
Apple and its fanboys scream that it's a blatant violation of ones privacy and that the only thing they do with the data is sell ads.
Three years later, Apple implements the feature that works in the exact same way with some privacy buzzword.

They should have kept it in, but bodged it so it always showed much more than you get. None of the users would have noticed, none of them are actually sitting there timing how long it is since they last charged up anyway.
If you want it back, just install iStat Menus Pro:

Sorry, which workstation operating system does Google produce again?
The users complaining in this thread don't get it.
That metric was so useless and inaccurate, just simply opening a new app would drastically change the "time remaining" for some time. So people would open up their favorite apps and then immediately check the "time remaining" and see that they're only expected to get 3 hours of battery life.
Since it was so adaptive, it was highly inaccurate. People can complain Apple is hiding the issue or whatever, but to me, percentage will tell you more about the actual battery life that the machine is expected to get.
EDIT: To users saying they should have tweaked the metric, I would say that the metric would remain be still inaccurate. It's very difficult to actually estimate time remaining (I say this as a software developer). There are certain things you can estimate, but generally, since it's all dependent on the user's actions, it's very difficult to predict what the battery life would be. There's a reason the iPhone doesn't have this metric too.
I think getting rid of the time remaining would actually remove that check having to be done in the background as well.

Welp ... that seals it. I'm not buying the 2016 MacBook Pro. They justified all sorts of compromises because it afforded "10 hour battery life", but now they can't deliver on the one thing that drove so many of those compromises, so you get the worst of all worlds.

Annoying, but I understand it.
"4 Hours Left" means nothing if you then open up YouTube and stream some videos.

No, it wasn't so inaccurate, it wasn't to the second accurate but was a pretty good indicator and has been for years. Whereas % full means absolutely nothing time wise.
This must've taken so much courage, right Apple?
It isn't even accurate to the hour. My estimations would wildly range from 3 hours to 11 hours at any given minute. It stressed me out. Though I was hoping more that they'd fix the algorithm, removing the estimation is not ideal either, but I can work without stressing too much.
Scott Forstall should release apology statement to Apple customers. 
No, can you imagine if they removed the Miles to Go indicator. They kept the % display.
All the people complaining about battery life are all probably using Chrome and have 15 tabs open.
