[Q] Qi wireless charging overheating.

Hello,
I have the i747 with the Jedi Invasion ROM and i'm using a wireless qi charger. The problem is that if I leave the phone on top of the wireless charger after a couple of hours it gets too hot. Anyone else is having a similar overheating problem with a wireless charging?

I have the same problem stock. Get the pop-up message: "Charging paused, temperature too high" or something like that.

Looks like a charger problem. Did you touch n see the surface you put phone on? If I can think straight, wireless charging happens by magnetic induction method, and this tends to heat the coils that turn this energy into electric energy needed for charging. Did you check with the manufacturer?

It is true, my problem was the charger. I bought a new "nokia" charger with the new slim qi pad and now my cell phone is not overheating.

Wireless Charging Questions.

Been thinking of getting a Wireless Charger for my N5 but I have a very important question. Will they work through a case? I use a case on my phone and there is absolutely no value to a wireless charger if I am going to have to remove my case to use it. So I am wondering if you can place it atop the charge station while in a TPU or plastic case and still get a charge? I would also like to know how much slower Wireless Charging is than regular AC charging? Thank you.

Yes, wireless chargers work with a case. I've used the LG WCP-700 wireless charger with my Nexus 4 flawlessly with countless cases on the Nexus 4. I fully expect the results to be the same with the Nexus 5. Wireless chargers are very convenient and work great. Just make sure to get a reputable one and don't cheap out on a $20 eBay one.

i also heard that once ur phone is fully charged..the wireless charger will stop charging

I know the LG one stops charging when full. It also trickle charges so if your phone or tablet falls below a 95% charge it starts charging it again till full, then stops again.

All "Qi" standard chargers will work with the N5 with varying degrees of success. They all will generally charge up to a distance of ~3-4mm from coil to coil so they will usually charge thru cases with no problem although there may be a slight degradation in charge rate. I have used several different Qi chargers - the Google Orb, the Owlpad car charger, the LG WCP 300 and the Metrans MWT03. They all charged my N4 'case on' with no trouble although the N4 did seem to charge slightly quicker without the case on. I even mounted the Metrans inside of my desk just under the laminate surface and it charged the N4 fine thru the laminate and TPU case. The Orb was easily the best of lot and charged the fastest, the Owlpad was probably the worst but it was used while driving with the phone generally being used for GPS, music streaming etc and under those conditions, it barely could maintain charge with screen on. With the phone off, it charged fine.
I just got my N5 today and tried it with all of my chargers and they all worked fine, if anything the N5 is less picky than the N4 about placement.

Shouldn't have problems charging through a case

Dit you try the N5 in the Owl Carpad? did it work or did you neet to do some mods?
I'm also looking at this charger

I bought the owlpad for my N4 and the N5 doesn't play well with my N4 Owlpad. The coils are not aligned and there is little wiggle room in the phone holder. Owlpad does make a N5 version (or a $29 conversion kit to make the N4 Owlpad into a N5 charger). Overall, I wouldn't recommend wireless charging for a car dock. Wireless chargers can't charge at the same rate as a cable and if you, like me, put heavy use on your phone while driving (GPS, bluetooth, music streaming, etc), the charger at best will barely maintain charge and often will lose charge. The beauty of wireless charging is being able to drop your phone at home or office and have it always 'topping off' without bothering to hook up a cable. If you put heavy use on your phone in the car, I recommend direct cable. For the home or office, I definitely recommend wireless. Since going wireless with my N4, my phone seems always fully charged when I leave home or work.

Yes, they will work though cases. I had a Diztronic on my N4 and it worked great. The charging is a bit slower but rapid charging isn't the point of the wireless chargers.

Has anyone tried the N5 on the WCP400 (the google Orb) yet? I will tonight but am curious (and impatient) while I'm here at work.
EDIT: someone has; here: http://forum.xda-developers.com/showthread.php?t=2513200

Charging rates: with/without a case, wireless vs. wall ?

So we have the easy answer here ("yes wireless charging works with a case") but no careful studies on charge rates.
The OP also asked how wireless charging rates compare to wired charging.
I would also like to know if and how much using a case for wireless charging affects the charge rate? I use the Google charger (I would post a working link but the XDA site is being *****y about my lack of participation) ( .. play.google.com/store/devices/details/Nexus_Wireless_Charger?id=nexus_wireless_charger ) which also includes a permanent magnet to help align the Nexus 5 to the charger. This is important because if the charging coils are not well aligned charging doesn't work at all and there is much less than a centimeter of margin. Using a case definitely weakens the alignment field because without a case the phone "snaps" to the correct position, whereas with a case you have to feel the alignment field and for the most part position the phone over the charger manually.
We know the distance between the phone and charger coils affects energy transfer (inverse square law for fields), but perhaps wireless chargers automatically adjust the strength of the charging field based on charging amperage or feedback from the phone to optimize charge rates? This would help mitigate the effect of a case but there would still be larger distances at which the field cannot optimally charge the phone. What are these distances, and do some chargers vary the charging field strength based on any kind of feedback?

[Q] lg g pad not charging properly

my g pad takes forever to charge. it could be charging for 2 hours and only get charged 10%.
I've tried charging it with the supplied charger as well as chargers for other tablets and the result is the same.
I remember back when I had a nook colour and if you would charge it with a different charger than the supplied one it would take forever because the nook color's charger had more pins to it or something, is this the case here with the g pad's cable?
is it the cables problem or do I have a faulty internal battery? I notice when I charge it the power brick, no matter which one I use, oem or not, doesn't heat up at all. before it would heat up a lot when it was charging but it doesn't now.

I had this problem with my GPad.
Not only was it slow charging for a wall charge.
But every 5 charge cycles it would be in the wall for 8 hours and would be at 20%
Way i fixed this was, put a QI mod into my GPad to enable charging wirelessly.
(It charges via USB) so it doesn't fry the Internals.
I've moded the Pad so it runs at lowest MHZ and lowest brightness whilst charging, adds an extra 3% an hour.
Hourly charge rate is about 12%
Best part is it hasn't had any charging bugs that I had with the wall charger,
Been using mod for about 5 months.
Alls I need to do is drop and go and it charges, very convenient.

If you're still under warranty, have it replaced. It appears to be defective.

Are you using the supplied charger and the heavy gauge usb cable? The cable also matters in this situation. I have a long thin cable that seems to charge several devices slower, which I wouldn't have believed until I had proof in front of me. If you are using the heavy gauge cable as well, then yes you must have a defect, contact LG for warranty if possible.

I had the same issues, it turned out my usb cable (probably got twisted and) is damaged internally.
Sometimes it works fine but it's kinda unreliable now.

Wireless charger charging very slow

Yes, I know that any other charger than pixel stand won't charge faster than 5W. But still, I've got baseus simple wireless charger (2A) and connected my pixel 3 xl for the night. It had about 45% before and about 55% in the morning. So it got about 10% in 6 hours. That's super slow. I've tested it in Ampere and it shown about 300mah. Charger itself is connected to rock wall charger with 2A power output. I'm also using Spiegen ruggee armor case. What's going on?

It seems that the baseus wireless charger is causing the problem

Try again without the case, a different charger block, and then again on a different wireless charger. I've been using wireless charging since the Nexus 6 and it can be a bunch of different things.
Generally I try to use a "matched" charging block to the wireless charger itself. For example, if it is a 2A wireless charging stand I'll pair it up with a 2A charging block not a QC 3.0 charging block. While this shouldn't make a difference it could be a problem.
I have multiple Itian wireless stands that I use for my iPhone X, Nexus 6, and Pixel 3 XL and I only have some minor issues.
One issue is that every once in a while I have to unplug and re-plug the micro USB cable into the charger because it just stops working for no reason. Other times it's something as simple as the phone isn't sitting in the stand correctly.
The way wireless charging works is through inductive coils and I bought the Itian wireless charging stands on purpose cause they have three coils reducing the issue of not properly setting the device in the cradle.
Unfortunately it's hard to say what it is exactly but try different things that seem logical as to why it isn't working for you. Good luck!

Similar here, I've been a wireless charger lover since Shamu and Nokia Icon. I still use the same Tylt Vue chargers. It charges slowly, but who cares, it's on the night stand and easily makes 100% by morning.

I have to say I've tried again few nights and it's working better. What matters is the position on the charger. If it's a bit off it charges slower. I guess case may be slowing it down as well.

Question Mous wireless charger and magnetic case overheating?

Hello everyone, is this happening only to me? I'm using the original Google wall adaptor with a Mous wireless charger and magnetic case. The wireless output is between 5W and 15W, so it should theoretically be fine. Instead, the charger overheats substantially, to the point that the phone stops charging at roughly 50%. Did anyone encounter similar issues?
Thanks in advance!

I have the wireless car vent mount and Limitless 3.0 on a Pixel 6 Pro and mine also overheated so much that the phone stopped charging itself to keep the temperature down. I realized though that I was using a car charger with much more power capability than the included adapter, so once I switched to the originally-included car adapter it actually heated up less. Maybe try a weaker wall adapter?

Thanks for the tip! I've contacted Mous and they confirmed the phone overheats as the charger constantly charges at maximum speed. I'm currently using the Google wall adapter, but I'll try with a weaker one and will let you know. Thanks again!
Update: that did the trick! Swapping the Google wall charger with a weaker one allowed the phone to continue charging until 100%. The charger still overheats and slows down the charging after a while, but at least it continues to charge until full.
Thanks again!
