Magic Mouse Battery drain in High Sierra?

[WilliamDu]

Both my mouse and keyboard batteries are draining much faster since installing HS. Same batteries used in rotation with same charger. Drainage rate at least doubled since HS. How about some comment Apple?

How about some comment Apple?

I hope you don't actually expect anyone from Apple to officially comment here, do you?

I can acknowledge: Both my Magic Trackpad as well as my Magic Mouse (came with 2013 iMac) drain much much faster with latest MacOS (High Sierra).
I've just applied the "factory-reset all connected devices" option (bluetooth -> debug menu, using <alt-option><shift> keys) ... see whether that helps.

This is NOT problem with your mouse and its batteries. This is Apple NOT supporting older hardware correctly. HS is not reading the battery power right and it shows incorrect % in indicator. I submitted bug report to Apple months ago on this. They send me eventually back e-mail, that they are closing the bug report as "Yes, we can reproduce this. But NO, we are not fixing it as these mice are obsolete devices. Buy new mouse with rechargeable built in battery. There it works right."
Yes, that is correct summary of their e-mail.
I have like 6 of these old mice and they seem to last longer than the original Macs themselves. I am not replacing them!
If you simply ignore the % battery value, you will find out, that it drops to something like 10% and then it lasts for long time. In reality, you will get about same life from the battery as in prior versions of OSX. I have learned to ignore the battery value.

It affects currently supported devices as well. I have Magic Trackpad 2 and as soon as I upgraded from macOS Sierra to macOS High Sierra (10.13.6) the battery started to drain pretty fast. It goes from 100% full charge down to zero in approximately 3 days now. Before it used to last about a week or two, depending on how heavily I used it (normally about 8-12 hours a day) and how frequently I forgot to turn it off when I'm not using it. This batter has been in use for about a year now. Initially, I thought maybe it's dying but the discharge is happening so abnormally fast and the battery isn't that old. It has gone through a modest number of recharge cycles. It must be a software issue. Clearly, many people besides me have noticed that macOS High Sierra is a major factor.

As others noted, when OS says battery has no juice it really doesn't. The device disconnects and needs to be recharged.
