Ask HN: Is your M1 Battery draining significantly faster in last week?

5 points by jorisboris ↗ HN
Trying to see if it's only me, or many people.

I used to be able to go through a full day and still have 50% left. Now it's drained at the end of the day.

Do you by any chance live in a place with really high temperatures the past week? London UK for example has been over 30 degrees and both my macbook and iphone batteries last significantly less.

As it happens for me in London also I haven't noticed a drop in battery performance, but then my stamina has been knocked and so I may not have been working my M1 as hard as usual...

Only reason I’ve noticed is cause my phone doesn’t last throughout the day as it used to do a week ago, and my usage according to “screen time” is “down 14% since last week”. But of course this isn’t anecdotal evidence at best.

Could have been it. I work and live in Thailand so it’s always hot, but might have Ben sitting outside more

No, my M1 and M2 devices (and my A15) have all been the same as normal.

No, the same. Have 13.5.2 installed on both.

What does your Battery system settings say?

What does the Energy tab in Activity Monitor indicate? Especially the "Energy Impact" and "12 hr Power" columns.

I usually keep it plugged in but when I don't I've noticed the battery has drained faster than I would have expected. That said; the few times lately that I've gone on battery, the drain speed has returned to what I would expect.

Check activity monitor and see if anything is wrong. My wife and my M1 Macbooks had iMessage go haywire a few weeks ago and they started chewing through CPU at 1000% usage.

no but ive ran into occasional issues where it's "plugged in" but not charging. I just pull it out and plug it back in to make sure it's on.

Not in the last week, but I've had to stop using Apple Notes because it absolutely eats battery. Use Activity Monitor to check energy usage and I bet Notes is your culprit.

I don’t use notes, but I’ll check activity monitor, thanks!

Not in the past week for me, but I have a M1 MacBook Air that started draining precipitously almost out of nowhere. The OS says the battery is healthy but it drains faster and requires more frequent charging than it did before.

Yes. It's been draining noticeably faster after last week's update. I can no longer get a full day's use.
