    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?

    Um....no! That is not in any way what it's supposed to do. BUT I would love to see a video of it!

    I use the upgraded choe qi charger. One for me and one for the wife. They work great!

    Out of curiosity, have you identified what it is that's making your phone "move" on the charger pad? I would be tempted to sit there and watch it to see what's happening.

    My only guess is that either the pad is not sitting level (not likely though) ... OR ... is your phone on "vibrate" for notifications, and when you get them, the vibration causes the phone to "move" or "spin" on the pad and eventually fall off?

    This. I could see it vibrating causing it to move off.

    I am with Gator -- I use the Choe charger and have no issues.

    Thanks for all the replies guys. No, I have not yet figured out what is causing this as I haven't been home yet to test it further. I will try to take some video of this lol. I thought maybe vibrations from messages/alerts might be causing this, and that could have been what caused this issue the first two times, but when I tried this the third time this morning, I was awake and right next to the phone and no vibrations occurred for those 10-ish minutes. I hope it is the vibrations as that makes the most sense and can be rectified. I will provide an update as soon as I have more info, and will certainly consider returning this pad and buying the Choe instead. Thanks everyone!

    I have only tried one wireless charger so far, and it's this one:

    http://www.amazon.com/gp/product/B00...cUvbUpU4422545

    It's the TechMatte Qi Wireless charging pad. Comes with the charging cord and "wall brick", but will work with any micro USB cord and brick.

    The pad is basically the exact same size as the phone, and the "texture" is like a satin matte rubbery finish, so it grips just fine. My phone is not on silent overnight - meaning, it still vibrates when notifications come in. However, in 4 nights, it's yet to move at all on the pad.

    It's got an LED indicator ... red when plugged in and not charging ... but turns green when the phone is set on it and the charging cycle starts. Not a necessary feature, but one that I find to be nice to have.

    This pad also stays "charging" even when the phone reaches 100% charge, which is great because it doesn't allow the phone to reach full charge at 2am, then stop charging for 4+ hours before I get up in the morning.

    Also, I should add, this charger does a pretty good job at charging the phone ... it's not super fast, but it's not slow either. Also, I have a TPU case and a hard plastic shell case that I use on my phone, and the charger still charges the phone just fine with either of the cases on.

    For only $23, I found this charger to be a real deal. I am going to order 1 or 2 more so I can have one in the office, and one more on spare to keep with me when on the go.

    Quick follow up question regarding the Choe, I see a square version, rectangular version, and round version; which ones do you guys have and recommend? The rectangular one (stadium) looks like it has a non-slip surface (cant tell on the other two) that might prevent my insanity the next time my phone vibrates lol

    Awesome, thanks for the info Wiggum! Ya, I think the surface of the RavPower pad may be contributing to my issue. I cant wait to get home, find out that its just the vibrations, and then feel like a complete *** all evening lol

    Have you thought about calling the Catholic church to perform an exorcism? I think they're free to members of the church, otherwise there will be a $100 charge for consultation and $1000 to perform the exorcism.

    I have a Samsung wireless charger, and mine spins off too, unless I use laser alignment and an atomic microscope to make sure it's dead level.

    Luckily I don't use wireless charging much because it absolutely sucks

    You may feel different about it -- I know I would feel like you do if I had to try really hard to get it working.. but I simply drop and walk away and it charges . I didn't nab the Samsung one due to that issue -- one of our reviewers says it "slides" and that instantly deterred me so I nabbed this... https://www.amazon.com/gp/product/B0...cUvbUpU4422668

    I would highly recommend it. I have one on my pc desk and it's the only way I charge at home . I keep the quick charger at work since I need quick juice there and there is a plug at my desk so it's not like the phone isn't near me.

    I use the Samsung wireless charger overnight and my phone doesn't move at all, however I usually shut my phone off or use blocking mode set to allow favorites only.

    Hey guys, here is the link to the video of the RavPower charger spinning my phone:
    https://drive.google.com/file/d/0Bxa...ew?usp=sharing
    Pretty crazy stuff lol

    As recommended, I ordered the Choe charger. After three nights of testing, I can confirm that the Choe charger does NOT do this. I assume the RavPower charger has this issue partly because of the raised power symbol in the middle. That is supposed to be non-slip surface, but it seems to act as a pivot point.

    I also posted this on another forum and a user stated that because of the smooth glass back, he had this problem all the time (but did not mention the charger he was using). He said (jokingly) a fan from across the room could move the phone. His solution was to get a case for the phone (dont remember the brand).

    Hope you all enjoy the video and Ill be honest, Im glad Im not crazy lol

    Glass surfaces tend to be slick. Totally understand not wanting a case but it would mitigate the sliding or spinning. Glad it worked for you.

    with no sound/audio on that video (which I understand, since it increases file size quite a bit) ... it's hard to understand how the phone could just be moving off the pad w/out ANY sort of vibration, motion, etc. causing it. Either that, or that table is drastically tilted (not level) ...

    Glass or no glass, slick or not slick, anything flat laying on anything flat is NOT going to just slide off like that ... not without "help".

    I would have to guess, maybe, that the computer or something else on that table is vibrating at a very slight but high rate ... and since the computer/device/whatever is on the table ... and the table is hard wood, and the charger pad has no "padding" on the bottom to absorb vibrations, etc. That those vibrations are translating into the pad, and causing the phone to very slowly slide/move off the pad.

    If it were ME ... I would try the charger pat on another surface, and/or put a folded up towel under the charger pad to dampen any vibrations, and THEN see if the phone continues to want to slide off the pad.

    In the end, it seems that the pad probably has very little texture to it so that it will grip the back of the phone better ... but that not withstanding, the phone should not, under any normal circumstances, be sliding off the charging pad.

    @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?

    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.

    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

    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.....
