Magic Mouse keeps losing connection

Just received a Magic Mouse for my birthday. Experienced this same issue, disconnection when lifting mouse and setting back down. This was out of the box, with the included Energizer Advanced batteries. Thankfully my gift giver also got me a Mobee Magic Charger that I was planning to use anyway, it replaces the whole bottom plate with it's own plate and rechargable battery in one structure and is mightly snug, solving the problem.

Disappointed this happened out of the box though. If battery size is slightly different between brands, and these Energizer batteries are have caused problems previously, then Apple should probably look into including different batteries from the factory.

Sane problem.

Followed solution of replacing batteries for Apple brand ones.

Problem solved 😉

. You are a Genius. Thank you!

Battery size is NOT the problem, think about it really. As noted previously, the springs are BIG. Blue tooth may be the problem for some.

For me it was EASY. Clean the contacts in the mouse. Qtip or pencil erraser will do the trick.

wave d is right. No chance that the battery size is the problem. The springs in the contacts can compensate a difference of approx. +/– 4 mm. Btw, after 10th July, when I posted my "alcohol solution", I didn't need to clean the contacts and batteries again. No problems with three mice in extensive daily work.

So glad i seen this! I was on my 2nd magic mouse and could'nt figure out what was going. Didn't realized it happened after i turned bluetooth on on my phone! When i called in was told off all the years tech had worked for apple i was the first with problem!!! yeah right!!

You are a genius!!! Thank you SO much. It started occuring right after I changed the batteries so as soon as I read your post, I knew it was my solution!

As an electronic engineer, having the same problems and seeing so many discussion groups on the matter, it is baffling. Because the solution is so stupidly simple. I put some aluminum foil on the + sides of the batteries and for the first time all works 100%. The mouse even connects itself, what it nearly never did before. All the other stuff like reset PRAM etc. is a waste of time. I forgot who gave me the tip but that was GREAT. Now where are the Apple engineers?

After months of being frustrated with my magic mouse connection issues, I've finally pinpointed the scenario in which it loses the connection. The frustrating part is I have no clue how to fix it.

My mouse loses it's connection during iPad syncing with iTunes. Why in the world that happens is a mystery to me!!

Anyone else see this pattern?

OK, if it is not the aluminum solution (see my post) that helps, difficult to say. How do you sync? Wifi? Or other? As the mouse uses bluetooth, I am not sure it could get "confused" by your iPad. Very strange. Maybe useles tip but try to sync with wifi off, use cable, and ipad also no wifi (my old iPad has no bluetooth, not sure aboput the new ones). I sync with the cable to USB port, no issues. But sure try the aluminum paper trick. Worked magis.

I have two MM on different computers. I notice that one looses the connection more easily than the other, but will always get it back after waiting several seconds and tapping it on the desk once or twice. For the most part, I find using Energizer AAs keeps a good connection, *UNTIL* the batteries start to get low. Then loosing the connection gets more frequent until they are replaced. I've yet to try using the Apple batteries or rechargables yet. I plan to order some today though.

You need to insert a bit of alu foil in the + terminals. Done.

I appreciate that it might work and have yet to try it, but it's really not a great solution for the long term. Better than nothing though, thanks. You're right, the Apple engineers need to step up to the plate and fix this.

No battery problem here, here is what I found. First, my grandson uses the keyboard and mouse constantly with his games that the batteries do get some hard work. And you have to keep your keyboard batteries up, as well as the mouse ones.

But here is what happened twice, one of our DOG HAIRS got stuck in the 'eye' of the mouse and once I took it out with tweezers, the mouse worked fine.

I find a little sausage of Blu-Tack under each battery sticks them into their cradles perfectly. Don't put padding on the outside, it will curve the access door outwards, making it more likely to drag on your desk and even get permanently out of shape. Just glue them in!

Thank you for the solution. I was struggling with this issue for months. 🙂
