950/950XL - QI charging...1.0 or 1.2 ?

[DavidinCT]

Anyone know ?

The new standard of QI was released about 5-6 months ago, this claimed with newer chargers, that phones would charge faster and the distance from the charger could be longer, meaning mounting chargers in stuff could be easier (hidden charger).

Anyone know or was there any specs listed any place that claimed what version it is ?

I'm going to say the newer version because they claimed it could charge 50% in only 30 mins.

Is that over QI or pulgged in ? As a new charger with it doing the new standard of Qualcom Quck Charge should be able to do this but, not over QI/wireless charging.

Anyone know for sure ?

That's plugged in via USB-C and ONLY when battery is critically low (10% and lower).

anyone figure this out, does the 950 / 950XL have QI charging 1.2 or the older 1.0 ?

Any word on this topic. I just got my lumia 950 and been trying to figure this out also. I've also been looking everywhere for a Qi charger 1.2v and haven't been able to find any, or at least find one that states its 1.2v. All the chargers I've found say 5mm. Haven't been able to find a Qi wireless charger that says it can charge from 40mm. If anyone can help, be greatly appreciated!

I used the one I got with my Lumia 1020 working ok

The devs of battery super saver did a test with the DT-904 charger and it charged from flat in ~2 hours, so I'm assuming that its Qi1.2. My Lumia 1520 used to take 4-5 hours to charge fully using the DT-901 charger and I'm sure that one is Qi1.0 (much slower).

After having done very intensive QI charging tests with the Lumia 950 XL and various QI chargers I am pretty confident that this phone is only supporting the 1.0 standard which equals 5 watt charging power.

This video made me curious as well but now that I also own the DT-904 charger I cannot reproduce this at all. At the very very best I can achieve 3:30 hrs full charge which equals 5W charging power.

The interesting part is that the QI chargers I use draw between 8-9 watts (using an amperemeter) while only 5 watts arrive in the phones battery at best. The difference ends up as heat which then slows down charging speed.

Something is definitely wrong with the Lumia 950 XL QI charging. My other Lumias (930, 1020, 925) show totally stable flat QI charging curves with only a slight drop at the end of charging. The 950 XL charging rate is up and down throughout the whole charging cycle.

Thx for taking the time to test for us. I salute you good sir.

I picked up a cheap Insignia Qi charger from Best Buy, works great. Very little heat if at all. Fully charged in the morning. Have not done any detailed tests. My phone rarely goes dead at end of day, but hovers around 40%.

Also picked up a TYLT VU Qi charger for the car as well. Also from Best Buy. Came in today. Tested it for a few hours. Seems to charge faster than I was using it. It was constantly on using GPS.
