[Solved] Re: simple mod to make DT-900 and DT-910 qi chargers work with 950XL
So, I posted that I moved the interior charging coils on one of my Qi charging stands. When I put the phone on it, it looked like it was charging, but actually it wasn't. And I would have had to un-solder the ground wire in it, and lengthen it, and then get it to the right position... and that's just too much work (as I have 3 of these that would need it).
I finally just bit the bullet and pulled the 950 XL's back plate off, carefully removed the sticker over the Qi charging coil, and moved it down about 3cm. I tried it a few times so it may vary for everyone. There's definitely enough room in the backplate for this.
It's pretty straightforward - my original fix was picking apart the 1020's charger back coil and adding it to the back. Which did work... but it make the case bulge a little too much and the connection was flaky.
Anyhow, I didn't take before / after pictures, but the phone charges on all my chargers - two stands (one modded), the flat one, and the car charger.
When you peel off the sticker, it will become obvious what you need to do... and what not to screw up.
- Step 1: Use an Xacto Knife to carefully pry up the sticker that covers the coil (don't rip it - you'll reuse it in about 2 min)
- Step 2: VERY CAREFULLY pry the Qi coil up from the phone's back plate evenly so it remains flat. Do not stress the connector wires.
- Step 3: Move the coil DOWN about 3cm. Basically, the top of the coil should be about 3-4mm below the center of the recessed ring you un-stuck the coil from. Re-position its connector wires carefully while you do this. You may need to pull about 1.5cm of wire from the coil itself in order to get it into position properly. I guess you want to keep the wires from kinking, and crossing over each other.
- Step 4: Try it (no sticker). - It will NOT charge well without the sticker. The charging stand light will blink.
- Step 4a: Do NOT waste time wondering why... if you get the Qi charging noise and light on / blinking, you're good.
- Step 5: Put the sticker back over it (it actually shields the EMF I guess from the Qi coil and the phone). Try to keep any connector wires that cross the coil perpendicular to the coil itself.
I've been running it like this for about 6 weeks with no difficulties on all my chargers, and an aftermarket charger.
YMMV. But this is the simplest fix (as people have probably figured out after looking at the inside of their charger stands).
The good news is that I didn't have to un-do that charger stand mod. I have one modded, and one not modded. They both work just fine.
The car charger is the biggest win for me...
Except its sticky pad is pretty gross now and doesn't quite adhere to the windshield anymore...
