[Q] Charging Questions - Nexus 7 (2013) Q&A

I had a couple questions about charging...
1. I forget what the exact terminology is but I believe the tablet charges at 1.3 amps(?). Is it bad if I use my Samsung GS3 charger that is 2 amps? Or my standard car charger? Mainly I am concerned about battery life in the long run, especially since I can't pop this one out like in my GS3.
2. Second, I am curious about wireless charging. I don't really care if it is fast or slow. I mainly want to know if there are an long term negatives like the battery wearing out faster than using a regular charger?
3. If anyone has any experience or knowledge with wireless chargers, I am looking to hear a couple recommendations so I can do some research about which one I would likely get.
Thanks for any help advice!

[Q] Charging stand capable of 2A/fast charge?

Hi all,
Long time lurker, first time poster here. I have searched, but the few threads I could find went cold a while ago with no definitive answer.
Does anyone know of a cradle / stand / dock charger that will utilise the full 2amp potential of my cable when charging?
When charging direct from the plug and cable, Battery Monitor app shows just shy of +1900mA (estimated, but good enough for me). When I connect the same cable to either of my two stands the app gives readings of 500mA - 700mA.
I thought the dock was just a dumb extention of the cable, and did not expect it to throttle the charge rate. Admittedly both stands are relatively cheap from Amazon, but both are 'designed for the Note 2' so would have thought the fast charging would have been a key feature..
Has anyone run into this problem? Anyone found a solution? Or am I just way too impatient? :laugh:
Cheers!
You need to install a kernel which supports it like Perseus ot redpill.

I'm currently using Note2Core EX v3.06. I guess it doesn't support 2A docks, but it does 2A charging cables. Can the phone tell the difference between the two? I was not aware.
Thanks
I should clarify I am only talking about charging from the mains. The cable alone gets 2A charging rates, but add any charging stand to the equation and I get just over a quarter of the speed I normally would.
If charging stand is considered usb then it would be normal

[Q] S3 wireless charging feature - worth it?

So for any of you out there using a Samsung Galaxy S3 with wireless charging accessories, I have some questions for you. I'm trying to decide on my next phone, which will be either a used Galaxy Note II or a used Samsung Galaxy S3 (Sprint variants both). Each has its pros and cons, and I'm divided between them. One big difference I noticed is that the Sprint Note II variant has the wireless charging pins omitted, making wireless charging impossible. The Sprint S3 has them included. I'm trying to decide if wireless charging is a nice enough feature to sway me one way or the other. Here are my questions:
Is charging the S3 noticably slower when using wireless charging?
Does it consume a lot more power when charging wirelessly vs wired?
Are the wireless charging pads out there pretty particular about orientation of placement, or is it pretty easy to just toss them on the pad and get a good charge?
In short, I'm just trying to find out if this feature is mostly hype, or if people are really liking it a lot.
1) it's faster than usb but slower than AC. (you can also modify it if you have a kernel that allows you to adjust the charging rate, but do this at your own risk)
2) not really that much more. I highly doubt you'll ever even notice a difference in your electricity bill. If you really want to be exact, then you might want to use a kill-a-watt and measure the difference from a certain range (say 50% to 100% on AC vs wireless)
3) they are slightly picky. it depends on whether or not you'll be using a thick case to go with it. In some cases, the bigger cases like the otterbox armor will not work, but cases like the ballistic Sg would work just fine but requires you to be slightly more accurate than using it without a case)
wireless charging is a convenience. I personally like it a lot because I don't have to plug it in all the time and it allows me to just place it and let it charge especially when i'm working at the office with little to no reception. it'll keep my phone topped off at all times even when my phone is constantly hunting for signals.

G3 Charging Question

Until about 10 days ago, I had a Galaxy S3. I was rooted and on Barren within an hour of having it home, and now I'm running BarRin. I don't know if this is relevant to my question.
On my S3, my car charger charged my phone at least as fast as my wall charger did. I'd say, even faster. I'm using the same car charger with my G3, and it charges very slowly. I use it most of the time when charging, but I used my S3 as well, and still it charged up quickly. When I'm plugged in at home, it charges quite quickly whether I'm using it or not.
Does anyone know what the difference is? Why would the car charger be so slow on this device?
Bigger battery and carger is giving low power output. Thats the reason for slower charging.
What are the charger specifications? How many ampers (A)?
There's no specs on the charger, so I can't say how many amps. I realize the battery is bigger, but the big disparity between the wall and car is what I'm questioning. The battery charges just as fast as my S3 out of the wall. It's just the car that's slow. I see your point, though, and you're probably right.
It's not a complaint. Just an observation. I've had nothing about this device that I can complain about. None of the issues I see some people having. Despite all the flaming people do, I'm very happy I chose the G3.
I had the same issue like you. But it was with previous phone.
Then I found good car charger and it was charging great.
If you are able test with few mire different car chargers. I even saw there are 2.1A car chargers. Havent tried them but I really dont know how can they get those power. Probably some chinese guys wrote 2.1A on them

[Q] few questions about the magnetic charger

for those who have it and used it for long time..
1) is it charging faster/slower/same than regularly charging? (with the same charger of course)
2) is it actually comfortable? after trying it, do you actually use it daily and enjoy or its a gimmick only and you went back to the regular cable?
3) is it causing any damages? bugs? weird stuffs?
I'm Z owner (it doesn't compatible with magnets) and I'm considering to upgrade to z2/3/3c with mainly reason of the magnetic charging..
Some experience sharing would really help me out here.. YouTube is only for unboxing and showing it but no real tips from experienced users..
Thanks.
Well about your concerns
1) is the same as the regular charging (but it depends on what type of magnetic charger you bought, I have bought some by ebay and after sometime it starts to give some problems, later I have bought the original from sony, so far no problem with that)
2) I use everyday, buuut I dont use the phone while charging, I just leave it there, its uncofortable to charge and use the phone, since it not a very strong magnet
3) no, no & no

Wireless Charging

Hi all, I'm considering getting this device, but want to have wireless charging.
has anyone purchased a 3rd party wireless charging receiver, and if so, what has been your experience? are you using a case?
thanks!
The Pixels do not natively support wireless charging. You will have to wait for a company to make a wireless charging case that adds this functionality.
For example, on the Pixel 1:

correct.
looking at the reviews on Amazon, many users are claiming that it works fine with the pixel 2.
I haven't used them, my only concern is how easy it would be to unplug the wireless charger in the even I need to access it either to charge or connect it to something like computer or God forbid headphones

100% agreed.
that's why I enjoy my droid turbo (built in wireless charging).
however, i MAY be fine with accepting this so long as the battery life is great as it has been claimed (able to go a full day in between charges), and I may ask for a pair of them google pixel ear buds for my birthday.
so the solution would be to get an extra wireless charging pad (less than $10) and get a pair of wireless earbuds.
but if the deal breaker for me would be the battery life. my current device as a 3900mAh battery and can go all day and then some. but, it is 2+ years old, and the battery is deteriorating, so it's not lasting as long. but if the Pixel 2 can deliver, then I may be fine with that.
Honestly battery life has been really good for me. I get 4+ hours of SoT which includes playing games and watching videos.

Oh, very cool, actually! I would also be worried about continuous unplug/replug for anyone using wired headphones or wanting to plug in for faster recharge. Let us know if you try it!
Lost wireless charging when I got the Nexux 5x. Never really missed it much. While somewhat convenient, it was slow to charge and many times when I needed a fast charge I just plugged in anyway.
So, Nexus 5X -> Pixel -> Pixel 2, same thing, I have chargers where I need them and charging is pretty quick. So, at the office, in my truck, by the recliner and in my home office I have fast chargers. I am covered. I also have a fast chargers in my backpack when I out an about.

understood that wireless charging is a preference and not a necessity.
as for me, it's more of a convenience factor as well as less wear/tear on the port (and battery life from my understanding). to have the ability to pick it up and go rather than pulling on a cord is a great help.
i did this with my wife's iPhone 7. and she really enjoys it (and it's difficult to get her to adopt to new technologies - hence why she has an iPhone).

I purchased the Spigen thin fit case and a Nillkin usb-c qi tag (short version). Have been using it for a few weeks and works with all my old Qi chargers used on my Nexus 6.
The case has a recessed area where the tag can sit without producing a bulge.
reddit.com/r/GooglePixel/comments/7an3sm/pixel_2_wireless_charging_solution_nillkin_qi_tag/
To throw my 2 cents in. Used a USB Type-C wireless receiver with my OG Pixel XL and it worked fine, as soon as received my PXL2 I connected the adapter but it was unfortunately insufficient to provide a decent charge, even over night, many times having the same or less battery percentage left than before laying it on the Qi charger. I have since tried 2 different wireless receivers with the same result. I've gotta believe they can manufacturer one that will out put enough juice to power and charge the battery. If anyone comes across one, please let the community know. TIA.
I've purchased the Nillkin short receiver and it does not work.
I charged it overnight in a thin Spigen case and it discharged 5% overnight.
I tried charging using the receiver outside of the case and at best pulled 0.31A on a 1.5A rated qi base.
What about one of the "Magsafe" type USB C cables (https://www.amazon.co.uk/COCHING-Magnetic-Charging-Lightning-Adapters/dp/B073HC1DJB/ref=sr_1_3?ie=UTF8&qid=1522506792&sr=8-3&keywords=usb+c+magnetic) if you're looking to reduce wear and tear? I assume you still get quick charge.
Looking at Nillkin's website, the tech specs on the USB-C "magic tag" give it a max output of 5V/1A. As we all know, Volts x Amps = charginess (or "Watts," for the electrical engineers). The power supply that comes with the Pixel 2 has an output of 5V/3A or 9V/2A.
So the phone's stock power supply charges at 15w or 18w. The Nillkin magic tag only feeds it 5w. At best, that's going to be a SLOOOOOOOOOW charge. The type 3 "fast charge edition" charger says it outputs more (10w). So the fast charger will send 10w to the magic tag, which will then feed 5w to your phone's battery.
Too bad. Seems like this could be a viable solution if there's a receiver that will output 10w. I mean, that still wouldn't charge as fast as the stock, wired power supply but at least it would probably charge. I'd love to have wireless charging with my new Pixel 2 but if the best it can do is 5 Watts, I'll live with the minor inconvenience of having to plug it in.
I thought wireless require all glass body which would be a no for me
