My phone Spins off Qi Charger, is this normal?

Re: Phone "Spins" off Qi Charger

@Wiggum - you're right about the audio, and there is an external hard drive next to it, so maybe thats causing the vibrations. I will definitely try this on more surfaces as you make a great point.

Still, after all of this, I believe it has to do with how Qi chargers operate:

Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery.

If the charger is very strong, the friction between the two items is drastically reduced, or there is some sort of resistance on the receiving device, then I can see where this could "spin" a phone/device in a consistent fashion. The strength of the charger, plus the slickness of the back of the phone, plus the pivot point on the charger = spinning. (IMO)

If it was just vibrations coming from something else on the table (not the phone or charger), then wouldnt the phone spin/vibrate in different directions based on the differing vibrations it is absorbing?

Re: Phone "Spins" off Qi Charger

Wiggum, you were right, I tried on other surfaces (with nothing else on them that could be causing a vibration) and it still spun. But when I put a folded up towel underneath it, the spinning was drastically reduced (although still present). I assume that means the charger itself is vibrating at a low frequency and when placed on a hard surface, those vibrations transfer up into the phone, which in turn causes a spinning motion on the pivot point. Geez, what a mess lol. I will let the company know what we found and stick with my Choe charger that doesnt have an issue being on a hard surface.

Re: Phone "Spins" off Qi Charger

As stupid as this sounds, I am now having the same issue with the Choe charger. Last night, I placed my phone on the charger, and within 20 minutes it had fallen off of the charging pad. While not as pronounced (and consistent) as the RavPower Charger, the issue seems to have returned. The Choe Charger gave me an issue the first night, was fine on the second and third night, and last night fell off while I was awake. I realize its likely not "spinning" off but rather "vibrating" off. I just don't have anything else on this night stand that is vibrating. And why would the Choe charger have worked two nights in a row (all night, phone was still properly aligned in the morning and was sitting on the same night stand in the same place) and came off the charger within 20 minutes last night. Im sure you guys are sick of this topic by now, and maybe Im missing something obvious, but Im getting irritated by this issue. I dont want to buy a third charging pad just to see if that will fix the problem, but maybe I should try out the one Wiggum suggested/uses. Thanks guys

Put a case on your phone and see if that helps.

Re: Phone "Spins" off Qi Charger

My phone does the EXACT same thing. It's so weird. Of course if I have it in it's case, the case prevents it form doing this but without the case, it slides off every single time. It's not caused by vibrations such as text messages or phone ringing. As soon as you place the phone on the charger, off it goes.....

Re: Phone "Spins" off Qi Charger

I bought the TechMatte Qi Wireless charging pad, had the exact same issue where the phone kept spinning very slowly and eventually fell off the charger. I simply wrapped 5-6 rubber bands around the charger and haven't had an issue since (close to a month).

Re: Phone "Spins" off Qi Charger

This is an old thread but the funny part is that this has been happening to my S6 Edge and I thought I was going crazy.. or my cats were doing something.. but I stared at it for a while and sure enough it was sliding off the wireless charger.

My Nexus 4 does this too! Both my husband and I have witnessed the phone tilting off our JETech charger and knocking onto the table with no visible explanation. My off-hand guess is something to do with electromagnetics. Like you, I also did a Google search about it and found not much other than this thread.

It happens several times a day - went sliding off as I was typing this. It happens whether the charger is plugged into my computer or a USB-prong plug.

Another oddity (and I don't know if it's related or not) is that, at times, apps start to randomly open and close while the phone is sitting on the charger. Again, I'm guessing it's electromagnetics. Hopefully we can get an explanation. I'd like to know how to reverse the tilting so that my phone will charge more reliably.

Re: Phone "Spins" off Qi Charger

I picked up a Galaxy S6 over the weekend and ordered a RavPower Qi Charger (RP-WCN7(B)) from Amazon, which arrived yesterday. (Note I had already drained phone to low charge level and charged via wall charger over the weekend, before receiving the Qi charger). Plugged in Qi charger last night, placed phone down, it started charging. Yay! I went to sleep.

Then something weird happened. I woke up this morning and found the phone had "twisted/spun" counter-clockwise and had fallen off the charger. Checked the battery level, and it seems that the phone must not have been on the charger for more than 15 minutes. I thought it was weird, but maybe there was an earthquake I didn't feel (I live in CA afterall). Put the phone back on the charger, and laid back down. Within 15 minutes, I heard a noise, looked over, the phone had done the same thing and fallen off. I put it back, checked after 10 minutes, and while the phone hadn't fallen off this time, it had clearly moved/spun slightly from where I placed it.

I tried Googling this issue and found NOTHING. I called RavPower and they said they had never heard of this, asked me to try it one more time tonight, if still experiencing the problem to send back to Amazon as this should NOT be happening.

Has ANYONE experienced or heard of anything like this happening, regardless of charger or phone? This is SO weird. While I don't know exactly how Qi charging works, I realize there are coils in there that are likely sending electrical currents in what I assume is a clockwise direction. Maybe the charger is too powerful? Will this damage my phone?? Or maybe my phone is too new and just needs to be broken in? I have no idea... Please help! Thanks! (sorry for the long post)

TL;DR: Phone spins counterclockwise off of Qi charger, wtf?

This happens due to induction. Wireless charging works by pulsing a magnetic field which in turn induces electricity into the coils inside the back of your phone. When the magnetic field attempts to cut through the coils it encounters magnetic resistance and possibly because the Qi spec allows the phone to communicate back to the charger. If you've ever tried to touch two magnets together with the same polarity facing each other, then you know how powerful it can be. The charger is literally levitating your phone off the charging pad. I know that this is a late reply, however other people might have this question in the future and all of the other answers given weren't correct.
