I Need a Drink

I just replaced the batteries in my Magic Mouse 1 two weeks ago on a secondary Mac that only gets a little use per day. Today the batteries were drained and I had to replace them. That's never happened on any of my Macs. Usually I can get several months on a set of batteries. Anyone else noticing excessive battery drain on their mouse?

I guess no one is having this issue. I just replaced the batteries in my mouse again today as the ones I put in 9 days ago are dead. Weird thing is, I have barely touched this computer since I replaced the batteries. If it had more than 20 minutes of use in the past 10 days, I'd be surprised. This problem only started after I updated to High Sierra. I am not having this issue with my mouse on my iMac that is also running High Sierra so I don't know what's going on.
 
I have that issue, but I don’t know if I can point the finger at High Sierra. I’ve gone through the last few sets of batteries fairly quickly, some of which were probably while on Sierra.

I attributed it to the Bluetooth issue I’m having. The mouse constantly disconnects and reconnects.

Try turning the mouse off when you are not using it, if it still drains then it is a fault in the mouse, not the (any) OS.
 
Anecdotally my mice (I have two) drain now (High Sierra) much faster than ever before. I have rechargeable batteries and used to recharge once per few months, consistently over few OSX versions. Now I may need it in week or two. It changed abruptly with HS upgrade - and these are not always the same batteries, so batteries are also not the issue. But keep in mind that this is really difficult to quantify reliably as few of us keep records on battery life in our mice.
 
My Li-ion Magic Mouse seems about the same. If there is increased drain, it's not hugely increased.

I don't use rechargeables in my AA battery powered one because my battery life with them (even envelops) has always been poor, regardless of the OS.
 
Something's going on. I tend to believe that it is High Sierra, as the batteries died a week after I installed it on my Mac Mini, I never had this problem in the past 3 years on other versions of macOS and I know there was around 80% left on them at the time because I have been in the habit of checking my battery status whenever I use a computer. I don't know why I do that. Anyway, as I said, I am not having the issue on my iMac. However, I have also noticed that my Mac Mini is warm when I touch it. I put an SSD in it about a year ago and I sometimes touch it to see if it is warm. Before High Sierra, it would be cold to the touch when I woke it from sleep, but now when I touch it after it's been sleeping for a while it is warm to the touch where the SSD is located. I checked my sleep settings and it is set to sleep after 10 minutes and the disk is set to sleep when possible. I do have power nap turned on, but that has been on since Yosemite with no problems.
 
This is definitely an OS issue. Both the old Magic Mouse and the new rechargeable Magic Mouse drain measurably faster since updating to High Sierra.

Interesting. I have been using the self-contained battery versions of the mouse and keyboard and experience no noticeable drain on the devices. I don't turn them off unless I am traveling, either. I utilize a work-from-home setup and use them about 9 hours each day. Right now my mouse is at 32% and I have not charged it in over a month, the keyboard is at 51% and I have not charged it since I purchased it at launch this year.

It doesn't make sense. I usually use rechargeable batteries in my mice, Eneloops or Amazon Basics, but I put in brand new regular AAs in the mouse for my Mini just to test this out. It was 100% on day one and by day 9, the green light wouldn't even light up. This happened twice. I don't believe it is the mouse itself as I think that something is keeping the Mini from sleeping properly causing the mouse to be connected 24 hours a day and as such, draining the batteries. I checked the mouse this morning and the battery percentage was down 5% since last night. It has to be High Sierra, as I've had this Mini for 3 years and the mouse never had this issue until I updated.
 
My rechargeable Magic Mouse is lasting longer with the new OS. Not a lot longer but I'll take every extra second.

You do know not all types/makes and brands of AA batts are the same right? Find the MaHr capacity of the regular AAs if you can and compare it with the capacity of the Li rechargeable or whatever you usually use...then you can compare, not before, thats just anecdotal noise tbh.
 
I am also experiencing rapid battery drain since upgrading to High Sierra, both on my mouse (magic mouse 1 with rechargeable Eneloop batteries) and trackpad (magic trackpad 1, with same rechargeable batteries).
Before High Sierra I was experiencing a different problem. On waking, the communication between my iMac and its keyboard would sometimes (often) be chaotic. I tracked this down to the trackpad, the problem was solved by turning the trackpad off until needed. It could also be fixed by turning the keyboard off and on again.
High Sierra solved this problem, so it appears that the behaviour of the bluetooth system has been changed. My suspicion is that bluetooth is polling the trackpad and mouse more frequently, stopping them from going to sleep as often as they used to - no evidence to support this, just a hypothesis.
The battery life of the keyboard seems unaffected.
My hope is a future update will resolve the issue.

Same issue here with the old trackpad A1339, no issue with the keyboard A1314...
 
It happened to me too with magic mouse and rechargeable batteries, but i used the mouse after the low battery notice, and i managed to use the last 10 percent for twice as long as the 100-10 percent. So maybe the batteries aren't draining faster, but the battery level indicator is working wrong.
 
Until a week ago, I was still running OSX El Captain because of software incompatibility issues. Two weeks ago I finally upgraded to High Sierra, and lo-and-behold, my mouse batteries are draining ridiculously quickly. I put a new pair in 7 days ago, and I just got the warning that they are low. This is the second occurrence since upgrading. I used to replace the batteries about once every 3-4 MONTHS! Something with the OS is definitely causing this.

I've been using the same brand and type of rechargeable batteries. Highly unlikely that four different batteries simultaneously crapped out, but I bought a new set of the same kind just to be sure.

Did anyone contact apple? I have the magic keyboard (which has a rechargeable battery built into it), and its battery life is unaffected. I wonder if this is some sort of gimmick to push people to buy the magic mouse 2, which is also rechargeable...
 
Mine too... I’m going through a set of coppertops per week since HS... MM1

They used to last me at least 2 months.

Tomorrow I’m going to hook it to my car battery ;)
 
Rechargeable MM seems about the same. When I was using rechargeables on my prior mouse, I noticed a degradation of battery life over time, whch I attributed to battery degradation. Rechargeables do not last forever. Towards the end of my use of the old mouse, I found I was getting longer life from regular AA batteries because the rechargeables had deteriorated.

I purchased new batteries and put them in this morning - they registered as 93% charged. 7 hours later, with only intermittent use, the batteries are at 88%. That's a 5% loss of battery life in 7 hours. Something is definitely up.
 
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.

My mouse does not continue to work when the battery gets low. It disconnects from Bluetooth.

I'm running the HS betas, so I'm not sure if they've changed something or not but in the last two beta updates, the battery level on the magic mouse, magic keyboard and magic trackpad all seem to be much better than late last year when this thread was started.
