get istat menus. it can replace a lot of things in the menu bar, including the clock and battery status, and it has a lot more functionality besides. you can monitor all the sensors in your system.

that said, no shit the time remaining is inaccurate. you mean the estimate changes based on what i'm doing? wow, who knew?

Welcome to the new Apple.

Sooner or later, even Gruber won't be able to deny that Tim Cook needs to go.

I know this is a longshot but anyone have Craig Federeighi's email?

I'd like to ask him something about macOS. I have no idea whether he'll reply but it's worth a shot.

No, it isn't.

Cook will completely destroy Apple. He'll do more damage than Ballmer did to Microsoft.

No. It's more like a car manufacturer suddenly turning off your car's 'miles remaining' indicator and changing it to just a dial because they sold you a gas guzzler with a tiny fuel tank.

No, it isn't. A "gas guzzler with a tiny fuel tank" is going to consume a predictable amount of fuel per mile, making distance to empty easy to calculate. Apple is removing an indicator that is difficult to estimate and therefore inaccurate. So, poor analogy.

The time remaining indicator is unreliable because the variance in outcomes is much higher. The idle battery usage is much lower, and the total capacity is smaller. If the peak current draw is the same, this results in a much wider variance in 'time remaining' with varying usage. This, by definition, leads to wildly varying or inaccurate 'time remaining' estimates.

Doing away with those isn't an unreasonable response to a bunch of complaints about those numbers being inaccurate.

I wouldn't be surprised if they come back in a future build, after tweaking the estimate to either be more conservative or increasing the bias of average current draw more heavily to more recent usage.

And Gruber is already walking back his snark on Twitter. What a fucking nitwit.

> Agreed. If an indicator is inaccurate, fix the indicator. But, percentage is the real measure. iOS has never had a "time remaining" measure.

So now it's OK for there to be no 'time remaining' measure.

The complaints aren't about the indicator being inaccurate. The complaints are about the battery life being shitty.

Um. Disagree?

> The reason for removing it is very simple: it wasn’t accurate.


I know there have been complaints about battery life. That doesn't mean time remaining was removed in a response to those.

It makes more sense that it was removed because it was inaccurate, and that's what the linked post claims as well. Do you have actual evidence to the contrary, or do you just like complaining?

City versus highway.

Predicting time to empty for a laptop depends on usage. Exactly like a vehicle.

Now if your reception is bad on your iPhone remember Apple pushed that update to simply show more bars of reception.

Too bad they can't get away with that one with something like battery life, so they removed time to empty entirely. Stay classy Apple.

this whole argument is fucking stupid. did anyone ever look at the time left indicator, and then get pissed off when it wasn't accurate? no, they just thought to themselves, "well, i guess my usage changed" or "i guess it's just an estimate after all."

btw, the iphone has no time left indicator, and no one gives a shit. the percentage remaining is just as good of a gauge as an inaccurate number of hours and minutes.

iOS is a mobile operating system. MacOS is a fully-featured desktop operating system.

You cannot compare restraints required for a mobile UI to what should be done for a desktop.

Unless you're Apple, in which case you've been spending the last few years saying 'fuck you' to your loyal desktop users.

You guys ever notice how new MBP's are EXACTLY 3 lbs and 4 lbs? Have you noticed in teardown videos how much free space is in them because the battery has shrunk? Have you noticed how battery Watt/Hrs has been reduced from 2015 model?

That's why battery's so shit.

Apple cares about how anorexic and light something is, not how well it performs or how long the battery lasts.

F U Cook!

This reminds me of the story about Jobs dropping an iPod prototype into an aquarium. Bubbles emerge. “Do better.”

Hey genius! Guess what battery indicator is still in place in OSX!

that's my point, dumbass. it's good enough on the phone, it's good enough on the mac as well.

Apologies, it sounded like you were bitching about the removal of the time indicator in your first paragraph.

Hey Dicknose. No shit. This is how it worked in the past. The previous heuristic doesn't seem to provide a useful signal with the new power consumption and energy storage profiles of the new macbook pros.

That's why it was removed.

Try to keep up?

thank you for the apology, you are truly a scholar and a gentleman.
