Wireless Charging meltdowns [Rev 1 hardware problem]

UPDATE January 1st 2016 Happy New Year
I can't figure out the Wireless Charging on this phone. I bought a LG Qi Circle Case. Still having issues. I went back to the stock back + my Rev.2 Qi Sticker.

It is still wonky. It was working for a while, then got worse and worse. It seems to have something to do with Quick Charging and wireless charging.

I think the phone has some weird bug where it gets used to the super fast quick charges and expects a specific amount of power, but then when you throw it on a slower Wireless Charger later, it still expects the same high inputs of power and just, maybe, keeps cutting the connection hoping for a better one.

I DID prop up my Qi Sticker charging tabs with a small roll of tape and it seems to be holding fine for now.

This really sucks. Between the Touchscreen issue, Qi Issues, and locked bootloader... I think this might be my last LG device.


UPDATE December 1st 2015
Still goofy. A factory reset seemed to help but it is iffy at best. Works perfect sometimes. On, off, on, off, no problem. Other (most) times just starts and stops constantly.

It seems now it'll charge for 5-10 minute before it starts getting wonky. Starts and charges for a while, then freaks out. Start, stop, start, stop, etc.

I woke up this morning with 43%.

I think the phone is faulty. I plan on swapping it via carrier warranty. Who knows if that's a good solution but my original G4 charged great after a few weeks of "breaking it in". It was wonky for a few weeks but ironed out and worked for months. My 2nd replacement phone worked for a few weeks and then stopped.

The initial success proved to be a fluke. At this point I factory Reset and now it is charging better.

Prior to the factory reset, I ordered a new V2 sticker. So that is 3 different stickers, 3 different batteries, and multiple Qi Chargers. All performed the same. As a last resort before replacing the device, I factory reset via Recovery (VolumeDown+Power on boot). I tested prior to doing any setup and it was working as it should. I even tested with the other stickers and batteries now charge normally after a factory reset.

So my initial conclusion went out the window. How a software reset could affect a hardware issue as simple as charging is beyond me. The only thing I can think of is a meltdown of some process. Typically reports (and even in my case) is that it typically works for about a month before it breaks down. Time will tell.

I have a Verizon VS986 btw. We are running on older 11A (latest) firmware. This may be something that gets patched out in other variants... hopefully.


UPDATE November 10th, 2015:
My Tests show it is the battery that causes the constant start/stop/start/stop > over heating > lockups

If you have a promotional or extended battery, try using that one. I have 2 LG G4s (1 replacement), 3 batteries, 2 Qi Backs, several Qi pucks. My issue/lockups/crashes/aggravation was only when I used my ORIGINAL OUT OF THE BOX BATTERY.

The Promotional Battery and the Out of the Box Battery are different. They have the same model number but different markings and text layouts. I think they are 2 different batteries. I think the included battery is faulty in some cases. I NEVER had any problems charging via hardwire though. Only Qi.

My theory is that the ORIGINAL battery just wasn't getting enough juice via the Qi charger to allow a charge. It sees the initial connection, but drops it for some reason and retries. This is why I think some pucks work better than others. Users have reported changing to a "higher quality" puck stopped the nightly reboots/lockups. Perhaps it was sending MORE power, enough to keep a steady charge flowing.

Where the PROMOTIONAL and Extended battery are normal and just take what they can get.

Makes sense right!

Original Post:
There are several Wireless Sticker threads and an issue that comes up is that while charging overnight, the phone freaks out and locks up. You can see the launcher icons, but the background resets to default and crashes constantly to a black background over and over until it resets. The problem is random and doesn't happen every night. Some times it happens multiple times a night. It seems there is an issue with the G4 ONCES it reaches 100. Possibly the constant "re-up" to maintain 100% is triggering some service meltdown. It is very odd. We have found that different chargers yield different results. I know some of the cheaper Qi pads will not trickle charge and just turn off after 100% (you wake up with 78% battery). Others have found different stickers have been the culprit. Some speculate the curve of the device causes the coils to not receive a constant charge (creates variances in mAh).

Something is causing it. I figured a dedicated thread to get to the bottom of it would help spread awareness and help get to the bottom of it.

All Wireless Charging users are encouraged to participate but posts such as "mine charges just fine" is not helpful here. So I want to try and stick to a format:

Code:

[b]G4 Model: [/b]
[b]Sticker or Official: [/b]
[b]Qi Charger: [/b]
[b]Launcher: [/b]
[b]DPI Used: [/b]
[b]Alarm Usage: [/b]

For me:
G4 Model: Verizon G4
Sticker or Official: Sticker from Ebay
Qi Charger: Nokia Puck
Launcher: Nova
DPI: 540 or 560 (can't remember but I changed it)
Alarm Usage: Used Daily for 7:30am

Aha, my HTC chargers output was only 1.0A and my LG WCP-300 should have a 1.8A input. Changed to the stock LG G4 charger to feed my WCP-300 and now I have not seen the issue again. I have also changed to a CFR-100 QuickCircle case.

So good charger + QuickCircle = no problems.
