[Q] Wireless Charging + Daydream Bizarre Performance

This is my first experience with wireless charging so I'm probably missing the obvious here so please, anybody, point that out.
I'm newly using a wireless charger with my N5 & performance just doesn't make any sense to me. It's the Korean/Chinese knock-off of the N4 Orb which others on XDA have used successfully. On basic charging it does work but I can't make any sense of these numbers:
Charging I get roughly 10% per hour -- not great, but okay for bedside/overnight.
Charging with daydream on (Dashclock) on I get a loss of roughly 10% per hour! Yes, the phone keeps indicating it is charging in spite of this heavy drain.
But sometimes daydream just turns off & it returns to charging -- this seems to happen if I start off with the phone (mostly) charged. For the most part though, if I leave the phone on the charger overnight with daydream enabled I'll wake to a nearly empty battery.
As I said, these numbers make no sense to me at all. Part of the problem may be the power source for the orb - it's only 1A but even if it's underpowered I can't see the drop from +10% to -10% /hour.
Second part of my query -- does anyone know if it would be effective (and safe!) to feed 1.2A to the orb & maybe get faster charge. Or maybe that would be enough to keep up with the Daydream drain?
FWIW the the USB charger (1.2A) is very fast, I get better than 1% per minute -- unaffected by Daydream.

im using this and mine gets full charge within 1 and half hours

10% per hour? Something's wrong. A wireless charger shouldn't take much longer than wired.
It's possible your adapter is a dud. Try using the 1.2a adapter, it'll be fine. If it still isn't faster, you might have a bad charger.
Also, if it came with a USB cable, don't use it. The wires are too small to carry a reasonable amount of current.

So I'm using DashClock also and when it doesn't crash, my phone will charge just fine. Seems like about 3 hours total with daydream on, and about 2 hours with it off just regular charging. Here's my charger: http://www.amazon.com/gp/product/B00DOW1RD0/ref=wms_ohs_product?ie=UTF8&psc=1. Seems like you have a defective charger but it is a really weird situation.

Thanks guys, the jump to 1.2A made a world of difference! It still seems strange, but I guess there's a minimum threshold for the phone to properly charge. (I am really guessing!) Plugging the OEM charger into my qi orb I finally get a positive charge with daydream -- not fast, but good enough to wake with a charged phone! Without daydream I just got about 36% in the past hour.
A quick scan of eBay and the only 1.2A USB supplies I can find are refurbished LG & cost as much as the full qi orb! (from US with crazy shipping costs on these - I'm in Canada) But there are lots of 1.5A blocks, cheap (and free shipping from China). So... do you think it would be safe to try the 1.5A? According to Play the Google qi comes with a 1.8A supply but I have no idea how much the pad modulates the power or if that is all in the phone itself. It would be nice to have fast wireless charging, but with the dramatic jump with just the .2A increase I may be looking at something too powerful.
My concerns are (in order) 1. Don't want to fry the phone!
2. Don't want to burn down my apartment!
3. Would rather not trash the orb. The orb was inexpensive so I'm willing to gamble on point # 3.
Advice / assurances / suggestions? Please.

I assume you mean USB out from PC since OEM charger is USB and orb power supply is USB as well. Point taken on PC charging though.

The official orb charger comes with a 1.8a brick. You should be fine.

I mean if your orb uses a USB cable and came with one, don't use the cable it came with. They're often very cheap and add a lot of resistance which will increase charge time.
It wasn't the step up to 1.2A that made a world of difference, it's using a quality adapter that made the difference. Your 1A adapter must have been faulty or grossly overrated. Sounds like it was putting out less than 500mA.
As for a higher amperage power supply somehow damaging things? Not possible. The circuitry in the wireless charger is only going to use what it needs, you could hook it up to a 50A power supply and it'll still draw around 1A. The N5 is also input current limited to 1.2A, so using a crazy high amperage adapter won't have much benefit anyway.
Still, not a bad idea to get a 1.5A - 2A adapter to compensate for whatever current the wireless charger itself uses. This is probably why the official one includes a 1.8A adapter.

So from what I heard wireless charging, like a pogo plug can charge at a higher rate than the micro USB port in some devices (I've heard pogo plug can go up to 2.5A where the micro USB in that device is limited to 1.8A). So I'm wondering as these qi chargers get better, will this also be true. Mine is a 1A but seems like it charges around .8A so it's maxed out. I guess this also raises the question as to how fast is good for a battery also.

[VIDEO] RavPower 2 in 1 Power Bank with Wireless QI Charging - Samsung Galaxy S5

This is the device that I used to do some underwater charging with the Samsung Galaxy S5. If you want to see that, please go here:
http://forum.xda-developers.com/showthread.php?t=2741481
Moving right along. I've used a lot of RavPower usb power banks. When I used to go out to the field a lot or traveled overseas, these things were super handy. Some of them have ridiculous capacities. I setup a hotspot for a group of 5 people in London for an entire day with a portable charger and HTC One X back in the day.
The RavPower 2 in 1 offers much less capacity than some of their other products, however the 4800mAh capacity will give you at least 1.5 full charges. This should get most power users through the day.
The QI charger has a little cool factor, but it is really useful. Say you go to lunch and want to put it on the table and charger it while you eat. There you go. Now you can. Plus you can check notifications, e-mails, etc without having any cords. Charge rates are reduced, but even at around half the charge rate vs the OEM cord it does an adequate job.
It can also be used as a replacement for a normal bed side QI charger. Just plug it in and it basically acts like a normal QI charging pad.
There's still a standard USB port present. Output for that is 1 full amp.
Not all of their power banks come with a charger since they have a common MicroUSB input, however this one does.
Most of their products are available on Amazon. This one is $56.99 shipped currently on Amazon.

Does it heat up really badly?

Not really bad, but just like all QI charging solutions, heat is a byproduct.

Thumb up for RAVPower. Got several of their portable battery chargers. Works great! And my favorite is the ravpower luster 3,000mAh that comes with a flashlight. Very handy. It worths more than it costs.

[Review] Tronsmart Quick Charge 2.0 54W 4 Port USB Car Charger

I have many chargers, but this one seems to be a winner for multiple ports with the added quick charge 2.0 port.
http://www.amazon.com/Qualcomm-Cert...mer-Included/dp/B00ZF7XLJU/ref=cm_rdp_product
I've had some more time reviewing this charger since I use it on a daily basis in my car. My original review is still true and can be found below. I've added a couple images of the product to show the quality of the finish as well as a size comparison between a couple other multi-port chargers I have. While this charger is the largest of my stash, it also provides the most charging ports while incorporating a quick charge 2.0 outlet. The size is a double edged sword in my opinion. Many 12v outlets are recessed, so the longer adapter of the Tronsmart charger can be quite beneficial. I know it would help in my Toyota Camry, but not so important in my Honda Odyssey. Due to the longer adapter size, I'm concerned I will one day drop something on it and damage my 12v outlet.
Anyways, on to the review.
Pros:
+4 USB charging ports (1 QuickCharge 2.0 + 3 auto detect 2.4Amp)
+Slim simple design
+No bright annoying LED
Cons:
-none to report (possibly the size)
The Tronsmart 4 port car charger is simply amazing. I have tested it thoroughly over the past week and have decided to use it as my primary car charger! I own many many car chargers, but there are very few that provide 4 powerful charging ports in such a compact design. This charger is rated at 54 watts, but all you really need to know is that it will charge all of your devices with ease. The primary advantage this car charger offers is the 4 port design with 1 being Qualcomm Quick Charger 2.0 certified. This means it is designed for long term use as new phones and products are just now being developed to work with this technology. The remaining 3 ports are not to be forgotten either, rated at 2.4 Amps each. They are also smart charging ports (Tronsmart calls them Volt IQ ports) which basically means the port will automatically sense and charge the connected device at its maximum rate.
I tested this charger using a variety of devices (Samsung Galaxy S6, S5, iPad, iPhone 6, and battery banks) and they all accepted the charge immediately and at similar charging currents as I've seen on with other chargers. My Galaxy S6 registers this charger as fast charging when connected to the Quick Charger 2.0 (blue) port. I used a Portapow V2 USB current meter to verify the charging rates while all four ports were in use. I alternated devices between the ports and the results are consistent with advertised rates. Through my experience testing many chargers, I've come to learn that the charging limitation comes down to either the charger, the USB cable, or the device itself. Rest assured that this car charger is not the limiting factor when you are maximizing your charging speeds.
I received this product at no charge in exchange for an honest review. I am using this charger on a daily basis as my primary charger, so I will update if I notice anything out of the ordinary. Please also let me know if you have any specific questions and I will do my best to answer them.

I agree. I also received this charger from Tronsmart, and it's been great!.
(Mine was sent for free, in exchange for my writing an honest review. [http://www.amazon.com/review/R9A6YSQ37WQZE] And, if I didn't like it, I wouldn't hesitate to say so. After all, it's a $20.00 item. Definitely not worth being a shill for that. Fortunately, I like it very much.)
The charger seems to be one of a number of quality items being manufactured in China, and repackaged under the Tronsmart, Anker, and Aukey brand. (Most of those items were purchased, including others from Tronsmart). But, this isn't a bad thing, as I've used many accessories from each over the past couple of years, and they've delivered good performance at a good price.
My setup is a Nexus 6, while my wife uses (my old) Nexus 5. We both drive Honda CR-Vs. My N6 charges quickly using the Qualcomm QC 2.0 port, although it also charges well with the Volt IQ "intelligent" ports as well. My wife's N5 charges quickly, too, albeit without the QC 2.0.
What I like about this charger is that it's still relatively small, despite having the 4 ports. This is VERY HANDY when my kids are in the car for a long drive, and their own tablets are sucking down battery life. When used with a longer USB cable from Tronsmart (or, Anker, which I've also purchased), they can charge from the back seat.
I bought a single-port Tronsmart QC 2.0 car charger, as well as a two-port Aukey (one port QC 2.0, one a "smart" charging port), and though they all work well, this is the one I have stuck with. Dependable, good quality, and very reasonably priced. If you have more than two devices to charge in the car, you can't really do much better than this at this price-point.

Nice car charger, I have bought a note 5. And also find that tronsmart has the dual 2.0 ports car charger. Both of the ports have QC 2.0. I will get it when it is available at amazon

The model you are talking already list on amazon, check it here:
http://www.amazon.com/Tronsmart-Qua...TF8&qid=1441770789&sr=8-12&keywords=tronsmart
it's great this model comes with two micro usb cables.

I bought this charger and am mostly happy with it. It does charge at fast charger rates most of the time. Sometimes I have to plug it in a second or third time before the phone recognizes it as a fast charger. The problem I have with it, is it won't stay in the car outlet. It is so skinny, and the side spring contacts cause it to continuously eject from my jeep power outlet. It will pop out just far enough that it will stop charging with out noticing it. Might have to rig it with tape or something.

Best option for pocketable USB-C power bank?

I'm looking for a quick charge power bank that would be comfortable to carry around in a pocket. Preferably one that supports USB-C. There doesn't appear to be very many options.
Here's a slim USB-C power bank that I really like the design of — https://www.ravpower.com/10000mah-portable-charger-Type-C-black.html — but there's absolutely no mention of quick charging. It also has a great warranty — 18 months that can apparently be extended for a lifetime.
However, this is the only one I could find that explicitly mentions QC 3.0 support, has USB-C, and is pocketable — https://www.amazon.com/Portable-ROMOSS-10000mAh-Resistance-Qualcomm/dp/B072X5PCV8 — but I'm not familiar with the brand and it would only be a 12 month warranty with that unfamiliar brand vs an 18+ month warranty with a more familiar brand.
Is the Romoss the one to go for or are there other options? Will the Ravpower still charge my phone quickly or should I stick to something that explicitly mentions QC?
Alternatively, I could just not worry about USB-C and go with Anker, who I'm pretty comfortable with and then I'd have a couple more options – either https://www.amazon.com/Anker-PowerCore-Upgraded-PowerIQ-Samsung/dp/B01NBQX0O5 or https://www.amazon.com/Upgraded-Anker-PowerCore-Qualcomm-Portable/dp/B01JIYWUBA. That would lead me to another question, though. Which is more pocketable and comfortable to carry? Compact but thick or tall but slim?

Honestly, I feel like this power bank from Anker does the job very well. Has USB-C charging along with two USB-A outputs to charge up to two devices at once.

Ok, that's a different thing.
That looks good, minus the fat design. For me personally, batteries that are thinner are preferable.

I keep a 6-port USB charger on my desk along with six different USB battery banks ranging from 3000mAh to 23600mAh. Most thin USB batteries that are "pocket-friendly" are going to be in the 5000-6000mAh range max, but my daily driver for USB battery charging is the 10000mAh Anker two-port charger with QC 3.0. It can charge my LG V20 from 10% to full in 1h30m a minimum of 3x before needing to be recharged itself, and it's only about the size of a pack of cigarettes and fits in my pants pocket next to my phone easily. My largest USB battery bank is so large you could actually beat someone to death with it and then connect the car charger alligator clips to jump-start your car and then drive home.

No wires included is just what I was looking for! I have so dang many - Thank you!!!

I'm curious if anyone has used any of these chargers for the Essential phone. I'm probably gonna grab the second one I link below and will test with my usb-c power meter and report back when I have time but if anyone else has direct experience I'd love to hear it.
This one looks a lot like what we need but it oddly states "not compatible with Essential" though there are reviews stating it does and does not work
https://smile.amazon.com/Nekteck-Ce...coding=UTF8&psc=1&refRID=RH73X9QDHJD8QPDN6DHG
This one has a little more power than the previous and does state that it works with essential though it claims that the PH1 negotiates via the 12V rail instead of the 9V meaning it is pulling less than 3Amps and therefore flags on the lockscreen as "charging slowly" even though it does charge fast.
https://smile.amazon.com/Nekteck-Ce...coding=UTF8&psc=1&refRID=RH73X9QDHJD8QPDN6DHG
This one is a nice looking wall charger but also oddly states not compatible even though it has the right specifications.
https://smile.amazon.com/Nekteck-Ce...coding=UTF8&psc=1&refRID=RH73X9QDHJD8QPDN6DHG
This one is wildly overkill for the PH1 and also states it has the same 12V rail thing as charger 2
https://smile.amazon.com/gp/product/B0721KG2Q7/ref=?ie=UTF8&m=A3GMRWNJ2V9TRM
This one has a built in cable but also states the same 12V rail bug
https://smile.amazon.com/gp/product/B0719KV9PH/ref=?ie=UTF8&m=A3GMRWNJ2V9TRM

So update...
I bought these two chargers off amazon, buy the car charger and the other charger is 50% off.
Both show charging rapidly when connected to the Essential phone so whatever mistake there used to be with it selecting the wrong rail or it not being reported correctly seems to not be an issue on oreo 8.1. I tested both with my usb-c meter and they seemed to provide something between 5 and 9 volts and anywhere from around 1 to 2.6 amps depending on charge level of the phone at the time.
Over all these seem like solid chargers and they are USB-IF certified so in theory the manufacturer isn't playing fast and loose with the charging specs like some do.

It costs more than the others, but I've never had an Aukey charger go south.

I got a https://www.amazon.com/Trianium-Charge-Charger-Samsung-Nintendo/dp/B01LXY0ECN . It has QC3.0 and PD. Works very well for me. Not the cheapest and it's one of the few which works very reliably after trying out more than 5 such chargers. Some don't supply enough power, some says they are PD but yet charges slowly. Only this one really worked for me. It's almost $20 but worth it for me
