Apple accused of lying about MacBook battery life

Not that I'm a fan of anything Apple does, but I'm wondering if these complainers aren't leaving their laptops in sleep mode rather than shutting them down. By default, MacOS's sleep mode keeps the RAM powered and perhaps there's an efficiency issue with that on the platform.

The headline misses the best part:

"“Apple promises up to 30 days standby time for the MacBook, but complaints posted online indicate that… users are only getting between 10 and 15 days,” stated the report."
What kind of computer do you not use for 10 days?? Are people expecting to go on a 15 day hike in the mountains, turn on the computer, and magically restore the OS to where it was when you left home??

The only battery number that's important to me is how long I can run on a full charge before I need to plug in again... Just checked, on current usage that would be seven hours and four minutes.

With both machines running High Sierra, I can close the lid on my old MB Air (mid 2013) and only lose 1 or 2 percent over 4 or 5 days. Overnight though, it will lose nothing.

But I lose 2 or 3 percent overnight on my new one (2017) or about 5% over 24 hours.

So the new one won't last 30 days but the old one would go much longer. Sure they are different specs, but they are in sleep mode so I'd expect much of a muchness. Maybe different battery manufacturers?

What battery app do you use? Coconut Battery doesn't give a lot of info.

I think it gives plenty of info. More than I'll ever need on a regular basis.

Including time remaining.

Not sure why apple removed that from the battery indicator.

People thought it was a lot more accurate than it is, which might have caused problems with people thinking their devices were cooked when it suddenly went from 5 hours to 2 hours because someone opened Chrome.

That is exactly what Apple is punting as standby time, being in sleep mode (hibernation really).

But the claimed figure would be from a 100% battery.

I wonder if these people run it down to 10 percent and then expect 30 days from it.

I've never actually measured but have left my Macbooks in sleep mode for weeks on end without a problem.

Is that because the new one has Power Nap and the old one didn't?

I wonder if Apple claim isn't just at the extreme with additional features off and likely listed in their claim.

Turning Power Nap off should give you way more time, should you need it that is.

MacOS distinguishes between sleep, hibernation and safe sleep. Sleep keeps RAM powered, hibernation copies RAM to startup drive and safe sleep does both. I doubt there are material battery life differences between them though unless something isn't working as intended, as any sleep mode keeps the processor in a low power state (among a few other things to enable quick bootup).

Not that any of that matters. Although I'm surprised that Apple is letting Dell run away from them in the battery life department.

It's because Apple keeps trying to make their already thing devices even thinner by lowering battery size to coincide with hardware efficiency. Bollocks.

That's with power nap turned off. And when I'm closing the lid, I've got very little loaded on the new machine compared to the old one (steam and Plex come to mind).

It kinda drove me nuts the first couple of weeks of owning the new one that the old one would not lose charge while sleeping but the new one did. But I sold the old one two days ago so I'm at peace with things now and enjoying the double sized RAM/HD and faster processor :p
