    I have the anker qi puck - don't think i've ever woken to find it at 100%

    Usually around 92-94%. I think it gets to fully charged then shutsdown and doesn't top up, hence dropping slowly [i usually stick on the plate at 10.30pm and take off at 7am].

    This morning it was really hot and at 18%!! I have a feeling i didn't put it on the puck correctly - i think it needs to be bang on over the middle.

    Rather annoying so far. Never had a problem with my Lumia930 and the small DT nokia puck that came in the box.

    That's exactly it! Of course QI needs some positioning to charge or not charge. But the 950 XL heats up so much when not perfectly aligned. I've never had this with my previous QI chargeable Lumia's. I really hope it's not a hardware problem like we've seen on some Android devices with certain metal alloys used (which apparently are magnetic and heat up even though they don't have anything to do with charging).

    I guess you could be right about the second charging cycle.
    To add my experience with Easychee 3 coil QI chargers (DT-904 will arrive soon, will restest): These chargers + 950 XL definetely dont start a second full charge when the phone is already in tickle charge mode.

    Heating up: When it heats up then it does so within just 1-2 hours = long before the phone is fully charged. The heat then slows down charging to a level where discharge is larger than (tiny) charge rate).

    FWIW, I have been using two DT-900 chargers that I had from the old Lumia 920 days, and while they both work, the phone heats up pretty badly. It might not be a problem with the charger, it could be that the CPU just goes crazy overnight, causing the charger to remain active all night. Each morning I end up picking up a pretty hot 950XL off the pad, with less than 100% in the battery. I'll try setting airplane mode next time, and disabling glance, Cortana, and Hello after that to see if any of those are the culprit.
    I word of warning.. I think the DT-900 (from the Fatboy pillow) MAY have cooked & killed Lumia 950.

    I only had the phone 14 days. First day back at work, I lay the 950 on the Fatboy pillow (like I'd done a thousand times with my old 920). After about an hour on the charger, I grab the phone & headed off to a meeting. The next time I went to use the phone, it was dead!

    Whether this is a fault with my specific Lumia 950... or something that could affect all 950s, I don't know.

    Fortunately my mobile provider has provided a replacement. In fact, I've used the opportunity to upgrade to a 950 XL (which I'll hopefully receive today or tomorrow :-D ).

    Because of this experience, I may not use the FatBoy pillow & will buy one of the new DT-904 chargers.

    The Aukey Wireless Charger, flat disc type that I've used with my Lumia 930 also works fine with my new 950 XL.

    DT-904 is literally the same as DT-903 with just the Nokia logo changed to Microsoft. My DT-903 makes my Lumia 950 XL very hot and charges very slow due to the overheating.

    I've compared the charging time between DT-900 and 903. 903 does charge the phone a tad faster (when using the 1.8A USB adapter from my 1520). I also tried a third party 2.4A adapter and the charging time is the same as the 1.8A adapter. However DT-903 is still very slow in charging 950XL.

    I also tried putting a heat sink (from my old CPU) directly contacting the metal plate at the bottom of DT-903. Not much different though. I think I'll need to test with a fan later.

    I think all of us have this universal frustration coming from wireless charging that we are so used to since the days of 920. I sure hope this is some kind of a driver/software issue and not hardware related.

    Tnx for your post. Yes pls try a USB fan as well. I've seen that it can impact the charging performance a lot but it's not the ultimate solution unfortunately.

    I believe that there must be another problem which either sits within the battery or the phone / firmware. Otherwise I couldn't explain why I now found similar charging slow downs on cable / USB-C charging.

    The whole situation is a mess. Never had a problem with charging a phone before.

    More inclined to say positioning is key, my dt 900 is fine with 950xl, I doesn't have fast charge but I get to 100% charge with or without leather wallet case on. Although I have known the leather to get warm at times but nicely cold when bare!

    Being in the same boat I was now looking for a stronger charger to go with charging plate off the 930, I am pretty sure slow charging and excess overheating is to do with charger not being powerful enough.
    Anyone have one of these perhaps?
    AUKEY 18W USB Wall Charger with Qualcomm Quick Charge 3.0

    This one does have 3A output which is same as AC 100 that comes with 950's, you can plug in any cable you want as well as charging plate, which should work?

    I am using Anker 20W (4 ampere max) wall chargers for driving my many QI charging plates and QI stands.
    Now the thing is that none of my QI chargers ever draws more than 9 watts. Because they can't: QI slow charging standard...

    It makes sense to use a wall charger with at least 1.5 ampere but 2+ ampere wont help charging speed due to the reason above.

    I figured this by measuring power consumption, ampere, volts, etc with a USB voltmeter.

    Sidenote: I also own an Anker Quick Charger 2.0 which I tested as well. QI charging plates wont make use of more than 5.x volts. Qualcomm Quick charge works based on 9V. Same is valid for USB-C charging (950 XL charger).

    Also: I strongly believe that investing into high quality wall chargers makes a lot of sense. They have smart charging functionality which figures out the best charging behavior. With my voltmeter I can actually see how it tries to find the best volt / ampere setting for each device.

    I did some volt and amp measurement on my DT-903 using both Aukey Qualcomm certified 2.0 wall charger (tested the quick charge port and the 2A port) and my Lumia 1520 wall charger (rated 1.5A output). Yup the voltage is always around 5.xV and the current maxed out at 1.5xA. This is certainly higher than DT-900 that is bundled with a .75A non-USB type wall adaptor.

    Using the 2A port on the Aukey charger on the DT-903, I tried placing my 950 XL in different orientation and position. It seems that placing the phone perfectly aligned with the top edge of the phone flush to the top of the plate where the cable comes out draws the max current. Placing the phone slightly off, the current drops to .7A. So I guess orientation is very important.

    I didn't notice this issue when using my 1520 last time. However, with the phone perfectly aligned, it still get quite hot and charging is slower than 1520, maybe of the bigger battery and higher current draw (less efficient) of Windows 10 Mobile.

    Well done and measured! Thanks for that - covers my measurements a 100%!

    Same for placement - "with the top edge of the phone flush to the top of the plate" - thats how I do it with the DT-903 / 950 XL as well.

    Yes the 950 XL still isnt capable of charging steadily with proper ampere. Thats why it's overheating I believe. In the first 20-40 minutes I see 8-9 watts being drawn from the charger which is far far above 5 watts slow QI charging standard. At the same time the phones battery only takes 5 watts. The rest (3-4 watts) ends up as pure heat. My theory :)

    Is it safe to use my Samsung charger? It's a Samsung wireless fast charger EP-PN920. When I place my 950xl on the charger it works fine and charges up pretty quickly. Is there any danger of damaging my battery?

    This charger indeed is interesting as it has a build in air fan (due to the high charging power / heat).

    From Samsung website, the output current is only 1A.
    Wireless Charger (Fast) | SAMSUNG Malaysia

    I guess the only advantage is it comes with a built-in fan.

    And I guess it means to say that it will take 120minutes to charge a 3000mAh battery. So 950 XL will take more than that.

    I have this same issue with three different chargers I have used for overnight charging including an original Nokia DT901. Shows as 100% then there is a sharp dip as the morning alarm goes off. I normally use it for a while checking emails, FB, weather forecast etc with my wake-up coffee then put it back on charge while I shower and dress so back up to 100% by the time I go out.

    These are the same chargers that when used in the living room for a charge in the middle of the day get up to a 100% and stay at 100% so like you I think it is do with trickle charging shutting down and not starting up again (combined with a glitch in my case with reporting of the charge status - I suspect that is due to having Glance being set off overnight). Does anyone know what the threshhold is for trickle charging to kick back in - 90%?

    Small update: So I got myself Anker charger with usb c cable. the new charger does it's job as should but when used with the plate off the 930 it is very hard to get it to start charging. On/off many times - nothing, then suddenly it kicks in. When I try with S6 Edge is all good every time. Makes me think that there is an issue with wireless charging on these phones at the moment, perhaps just software. Will try with Samsung plate next and see. Never had these issues with 930...

    Thing is I always charge phone overnight, so it may be a while until I get to check time it takes do do full charge, but will see.

    So I decided to check how long it takes to charge today, since getting the 3Ah Anker charger and borrowed Samsung charging plate - from dead to 100% it took 3.5 hrs.
    In 1.5 hrs it was at 48%. Phone stayed warm all the time but not too hot. Still need to check how long wired Anker charger takes to charge phone fully. I think I will get Samsung plate for myself also, since my 930 will be going for sale soon and DT-601 plate does not work with 950 well.
