Hiking today I noticed my compass was acting up. When I got it home and checked it I discovered it’s now pointing in the opposite direction! The red end now points south!

I have my phone in a Mophie wireless recharge case and it turns out those cases have magnets in them used to help it line up properly with the base station. My compass was next to my phone and got reverse magnetized!

So be careful with those wireless charge cases!

Mophie has made wireless charge cases for the iPhone for a while. Mine is an iPhone 7.

Sounds like the case caused the problem, not the phone.

I used to keep my Mophie cased phone in the same pocket with my hotel key card when I traveled. After having to go to the front desk for a new key card several times, I discovered I should no longer be doing that.

Notwithstanding, for those who don’t know, the Mophie cases are amazing. You snap the phone in, the case has a lightning tip in it so that goes into the phone. Then you plug it in to charge, and it charges the case and the phone.

Then, you either leave the case switch on, in which case it depletes the case battery before touching the phone battery. Or, like I do, use your phone as per normal, then hit the switch when the phone battery is depleted. Goes right back to 100%.

The cases are a little bulky/ heavy, so I don’t really use mine day to day. Now since I upgraded my phone (and yes, bought a new Mophie), I need it much less. But when I’m on vacation, which includes heavy phone usage to find stuff as well as for pictures, I find it indispensable. When my 5s battery could barely last half a day anymore, it was how I got through many a day.

A lot of people have those portable battery packs, which are fine, but it’s another thing to carry and another thing to charge. The Mophie integrates everything into one package, and you don’t have a battery pack dangling, you can use your phone normally while charging.

Available on Amazon, of course. Mine’s red.

Yes it actually was the magnets in the phone case that did it. I suspect it could also erase the strip on your credit card.

Mfitz804 that’s the same juice pack I’m using. Works great, except I need to be more mindful about the magnets.

Yup, once you keep your magnetized stuff away from it you’ll be all set!!!

Of course, your iPhone has a compass in utilities so all is not lost!

Yes, the iPhone does have a compass but it's not designed to work with real maps like a baseplate compass.

My wife had a Mophie case on her 6s and I had the Apple battery case on mine. I liked the Apple case better. No buttons or switches and it integrated with iOS. After a couple months her Mophie case stopped working properly. It wouldn’t charge sometimes. Then it stopped charging.

Actually, the battery in the 7 series impresses. I flew home from Reno yesterday and my 7 Plus was still at 47% this morning. Apple doesn’t make a battery case for the 7 Plus but I don’t see the need for one.

I've been using Anker battery backups. The first one I picked up about 6 years ago is 9,000 mah, it still works perfectly, I've purchased a larger one @ 16,000 mah. This one has the smart IQ USB port.

I keep them topped of with the Anker 5 and 15 watt flexible solar panels I can strap to my backpack, bike or canoe. I use the phone as my GPS when riding the bike, it's pluged into the smaller Anker which is hooked up to a 5 watt ridged solar panel.

When I'm just putzing around I usually keep most of the phone shut down in airplane mode, unless I'm in an area with a strong signal.

So after researching this on the good ole internet, it's turning out that in today's modern world there are quite a few things that can reverse magnetize a compass. Some examples I read of:

Putting a compass in the side door pocket of your car (next to the door speaker).

Certain types of clothing now have small rare earth magnets used to keep pockets closed. (I had a leather brief case like this)

Practically anything with a permanent magnet loudspeaker including pocket radios, 2-way radios, etc.

Cellphone cases with magnets - this is what did my compass in. I did not even know there were magnets in the case until it was too late.

Some eyeglass cases have rare earth magnets used to keep the case closed. I have one of these also.

Close proximity to a wire that can draw significant current, such as starting a motor.

Other examples also but you get the idea.

Procedures are described for re-magnetizing your compass back the correct way, and the companies will fix it, usually at no cost, but I don't think would ever trust a compass once it's been reversed like that.

The write ups also mentioned situations where search and rescue had to be dispatched to locate lost hikers with reversed compasses that didn't know it.

So I bought another baseplate compass and I'm planning to keep it in a separate pocket away from other stuff from now on.

Overcast days and the tree canopy here in the Virginia mountains makes it near impossible to use the sun for direction most of the time.

I'd better check my own Brunton Compass. Perhaps we indeed experienced a geomagnetic polarity reversal.

Yea I learned it’s a good idea to check it regularly.
