[Q] T889 Wireless Charging Mod

For those of you who have tried the wireless charging mod for the T889 version of the SGN2, do you get a voltage drop across the receiver coils with the phone not charging on the Touchstone but powered up? What about NOT charging but powered off? I'm just wondering if the missing hardware controller shuts off power to the receiver coil when the phone is not in wireless charging mode. Do you notice a drop in battery usage time or no drop at all?
Anyone have access to the N7100 version that can verify this?
I'm contemplating applying this mod, but I also want some control over when the receiver coil is active. [I was hoping to post this under the developer thread started by Vinas1, but don't have posting rights to that area yet. I need to pay my dues with 10 posts]

Wireless charging is not much current. I think around standard usb current which is 500mah. The stock charger is 2000mah (2amps). So that means when in wireless charging if you have the screen on it will most likely not charge but keep it at whatever percent it is currently at. If you are doing anything else as well like GPS you can expect it to drain on wireless charging.

Wireless Charging Glitchy

I have my ls990 on BarePop, which is the only option that I know of that has a working NFC. I'm all set up for wireless charging with the wireless sticker on the inside of my cover and if course the wireless charger.
When I set it on the circle, it starts to charge, gives me the warning that charging is slower than plugging in, shows charging for another 3 or 4 seconds, and then stops charging. This has been an issue since I hooked myself up. The charging drops after about 15 seconds.
I wonder if it's a shoddy sticker (which looks to be correctly placed) or a funky charger (Ankor from Amazon). Has anyone experienced this symptom or know what the problem could be?

Did you use a power adapter that is rated 1.5A or above? I used my old Nexus 5 charger (rated 1.3A) and my Qi charging is cutting on and off. Once I changed back to the original G3 charger, the Qi charging is stable.

That might be a really good call! I thought it was a good charger by a trusted manufacturer, but I checked and it's only a 1 amp output Anker. Makes sense, especially if you had similar symptoms with a low amp device.
Thanks for responding!

Overheating during charge with Qi charger

I used a cheap Qi charger (JeTech Ultra Slim Qi charger to be exact) to test wireless charging on my N5. I started it at 14%, and then when it reached around 30%, it began to heat up. Checked the temp with Ampere and it was 39º C, so I cooled it down for a bit and tried again, just to experience the same issue again.
I'm currently looking for a wireless charger that doesn't heat up my phone to that magnitude. I fear it might damage the battery, causing it to bulge and/or explode...

The same happened with one of my ravpower with chargers (black) . They replaced it free even though it was a year old. I also have the white one which, so far, hasn't had any issues. It's 8 mos. I have other products from RAVPOWER that have yet to quit on me.

This happens when the charging current is too low which is common in cheap chargers. This also happens to me when I misalign the charger i.e. when the charger is to far away from the phone's induction coil.
You could try to reposition your phone on the charger and see if that helps.

I got the nexus qi charger, don't know the temp but it didn't get hot when I touch it, same story for my G3 and Note 5 with LG/Samsung qi charger

i think heating is normal while charging

Charging pausing

I have searched and found this issue with note 5 but nothing on note 7. Wireless charging pausing? Wife's and mine both doing it on oem fast charging pads. Are these defective or is there a setting buried I havnt found?

an update to myself I guess, this is only happening with the OEM Samsung fast wireless chargers. every other wireless charger I tried, fast or not does not do this.
On a side not about the Sammy wireless charger, the lip the phone is supposed to sit on is quite small

Any chance your Samsung chargers could be overheating?

they dont seem to get hot at all when they do work

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!
