Hello all,
So I just bought a new charger (just a wall charger) and now when I plug my TB in, the screen does not respond to anything! I have to take the plug out to work my screen. It is completely unresponsive (regardless of where I'm at on the screen) while charging. As soon as I unplug it, it's fine.
Any ideas?
Where did you buy the charger from? Some crappy no-name/ebay/cheap chargers do that because they are crap. I had bought a cheap charger for my HTC Touch Pro 2 and that same thing happened, used the regular charger, no problems at all.
I know when I used the charger and cable that came with the thunderbolt, it used to become laggy or less responsive. Not terrible, but I could notice it. It was like all the memory was tied up. It doesn't do it anymore though. I rarely use the original cable and charger anyways.

Indeed. The cheap $1.00 chargers may also harm your battery.

Today I tried to charge my phone at work using my original.al charger that I always use and while it was plugged in, the screen wouldn't respond at all. I thought the phone was the problem but I later troubleshot it to low voltage from the extension cord, not my charger.
There are in fact quite a few micro-usb chargers that cause the screen to become unresponsive when plugged in.. This doesn't necessarily mean that the charger is crap, but it's best to use your manufacturer-approved (oem) chargers whenever possible. I work in wireless, and although our supplier is reputable, their generic chargers don't work well with the Atrix & a few other smartphones. I use them only when necessary, but do your phone a favor & stick to manufacturer chargers.
I had this problem, when I use a properly grounded surge protector the problem doesn't happen any more. It also happens to me when I charge out of my old macbook pro which tends to have a 'staticy' feel to it.

You're two months late with your incorrect post. There's a well defined standard for USB chargers, which the TB follows. Non-OEM ones work every bit as well as the HTC one as long as they, too, follow the standard and provide clean power.

Sorry my timing bothered you I was just browsing around for info about the touchscreen issues i've seen. I'm well aware of the standard, 5 +/- 0.25 volts 500–900 mA, and they all seem to charge perfectly well but certain phone/charger combos cause some screens to lag & I just wondered why. For example the motorola adapters all seem to be 5.1 volts @ 850mA, whereas samsung adapters are 5.0 volts @ 700 mA, and the samsungs charge fine on our standard 5/500's while the moto's lag.

It's not clear where the "500-900 mA" and "standard 5/500" figures you give come from. Neither is from the USB Battery Charging Specification.
The spec supports up to a 1.5 A current from a Dedicated Charging Port. The HTC charger is rated at 1 A, and it seems the TB will use all of it. I've seen charging rates of 800 mA, with the phone also running screen, GPS, and more.
Cheap ones, regardless of output, may be poorly filtered with a significant AC component. Those are the ones which will really cause problems.
One of the things I loved most about my Nexus 4 was just how quickly it charged. And unlike my SGSII before it, it could even gain a charge while being actively used for Waze. Really great.
With the 5 I'm back to where I was. And thanks to tools I picked up during the 4, I'm able to see why more easily. Seems on the exact same chargers I used my 4 on, I'm easily pulling 400+mA less than the 4 did from the same device and same cable.
I haven't had time to draw a correlation yet, but last night at home on a multi-out adapter from Monoprice I was able to pull over 1200mA which is more than I've ever seen ANY of my devices pull before. But today, on the same model at my office, but with a different cable, I'm pulling around 200mA. Same as what I was getting in my car, which would frequently dip into the negatives, and that was WITHOUT Waze running. Also of note, in ALL of these locations it's being listed as "USB plugged" instead of "AC plugged." I'd say that accounts for the difference there, but the 1200mA draw was listed the same way, so I doubt it.
So, has anyone else noticed this yet and found any correlations between devices, cables, etc., so we can figure this out? Using more power than it takes in will not be something I can survive with and will definitely make this phone a less-than-ideal upgrade over the 4 in the battery life department. But it's pretty clear it's not impossible to get a good charge.
(and yes, before anyone asks, all of my adapters have jacks with a minimum of 1A out, and each also has a 2.1A port. Surprisingly, unlike my 4 which tended to draw LESS power from the 2.1A port, the 5 appears to be unconcerned by the difference, pulling the same poor number from both)
Yes, i agree with you. I just check today, charging my phone from the pc and it seems fast charge isn't doing its thing.

Well, I haven't even dared test it from a PC yet. All I can say is from wall warts and car chargers it's terrible. I can't imagine how bad it is from the limited PC ports. Although it's probably exactly the same, since it seems to be identifying all my wall outlets as USB connections.

Not too surprising. I've read other reports that it charges nice and fast with the stock charger, which is likely the same as the G2 charger since they share most of the same hardware. But that doesn't help with car charging or those of us who've consolidated into multi-port chargers.
When I get home I'm going to mix and match some cables and devices and try to narrow in a bit more. This sounds like the Nexus 7 (2012) goose chase all over again.
The USB/AC detection is done with a definied resistance. Some chargers don't meet those exact resistances (cheap resistors have a big tolerance) -> the phone detects it as USB.
The cable can make big difference, I've tested several different cables on the N4 once, charging rate was between 600mA and ~1100mA (which should be the max) on the same charger.
Maybe the resistance in the charger is right inside the resistance tolerance, so the slight difference in resistance between the cables is enough.
Since the N4 most probably uses a different charge IC than the N5 (I haven't checked tho), it could be that the N4 had a wider tolerance than the N5.
What should help are those charge cables , the one I'm using from Porta Pow can only be used for charging therefore ignoring the charger resistance -> phone should always detect it as AC(even on a PC). Another good thing about those cables is the big wire diameter. Or a kernel where you can force AC charging regardless of the actual source.("fast charge")
That all sounds pretty logical. Considering I got much better results with the Monoprice premium cables I used last night (which oddly, are much THINNER than the cheaper ones), I'm going to experiment with those this evening and see if that makes all the difference.
As for kernels, I'm not planning to root this one if I can help it. I managed to get through the life of my 4 without rooting, too. I know it's heresy on XDA not to root, and until I got Nexus devices I would have agreed. But since stock Jelly Bean I haven't felt that burning need to "take back" control of my phone. I seem to already have plenty.
I observed the same inconsistencies with the N5's charging behavior and did some qualitative tests. I've attached a screenshot with my findings.
The phone is clearly capable of charging rapidly. My primary focus is getting a high current off the car charger. Is there a way to force AC charging mode vs. USB charging, or should I focus on more quality cables / adapters?
Just did some additional testing of my own and found some interesting results. I didn't take perfect notes, but here's what I got:
With the Monoprice 4-port Wall Charger 2.1A 8856:
Cheap Monoprice cable: bad charging, fluctuating between -80A and 200A.
Cheap unknown cable: same as above.
Monoprice premium 3ft cable: 900-1200A.
Monoprice premium 6ft cable: 700-900A.
With the Monoprice 1A car charger 6765:
Bad charging with all cables tried.
With the Monoprice 2.1A car charger 8858:
Bad charging with all cables tried, with exception of Monoprice premium 3ft cable which had same low end, but occasionally bumped over 300A.
With 3.1 (split between two ports) charger purchased on Amazon (my standby for my Nexus 4:
Bad charging with all cables tried.
With Monoprice 2-port USB Car Charger 3.1A 10071:
Cheap Monoprice cable: Bad charging
Cheap unknown cable: Bad charging
Monoprice premium 3ft cable: 700-900A
So it looks like high-end Monoprice paired with high-end Monoprice pays off. Unfortunately there's a rather serious catch with model 10071: it KILLS GPS. At least it did on my Nexus 4, and other reviews reported it as well. I can't be certain yet about it on the 5, but the little experimenting I did in the parking lot showed some anomalies I didn't like. Which means I apparently get to choose between GPS killing my battery, or charging my battery killing my GPS.
Also tried Nexus 7 2012 charger with its own cable and got bad charging, too.

There's a pattern obviously, the 6ft to 3ft drop seems high but is ok I guess.
I've never seen such a picky device when it comes down to charging, usually it just works as expected ^^
Have you tried your cables on the carger it came with ? Or the cable it came with on your other cargers ?
Is there something with "AWG" written on your cables ?
@random_dgp: Well you basically have 2 choices: get a kernel with (force) fast charge support (don't know if there is one yet) or get a charger/cable combo which works.
If you're planning on rooting your N5 anyway I would go for the kernel way I guess, since the charger and the cable are fine most probably, they just aren't in the specs the N5 requires.

The first-gen Nexus 7 was at least this bad. Actually its biggest problem was it refused to even ADMIT it was charging (even though it was) off of most devices. In fact everything I just listed it would claim wasn't even connected to it. A few hours later it was full, but it refused to recognize it. 4.2 fixed that, but it was still slow off of most devices. This at least admits it's being charged, but barely is.
And no, I haven't tried the stock charger yet. I guess I will, but it's not a high priority since it doesn't cover my issues.

i dont know if you're making this up, or if i have a defective nexus 4 lol
before i optimized my N4 i was getting about 4-5 hours of screen time, but it took at least 3 full hours to charge. that charge time to usage time ratio was killing me.
i am having much much much better results with my N5. i have no reason to charge it through a USB port on the computer(are you using an USB 1.0 port or something?), but charging it with the charger that it came with, i get a full charge in about 2 hours.
my N5 will charge a tiny bit over 1% per minute(while on or off), until it gets to 80% and then it charges at about .5% per minute or something
if you're getting the same charge times on the wall charger then i think you might have a defective charger/device. testing this will also be a good way to find out if it's just a slow usb port too

The problem he's having isn't about a computer USB port at all, the problem is that the N5 thinks it's plugged in a computer and limits the current to 500mA to meet the USB specs (and don't blow up some usb ports without a fuse somewhere) but in reality it's plugged in a wall charger.
His phone should be fine since it's working as expected on some carger/cable combos.
Btw. the N5 isn't pulling more current than the N4(both 1,2A), so it should charge almost exactly as fast/slow as the N4. It should even be a bit slower since the battery is slightly bigger I think.

I'm simply using the app Battery Monitor Widget. Really handy tool that solved some problems for me on the 4 with some weird charging situations. While I'm sure it's not insanely precise, it reflects my draining or charging rate well enough to show me what's going on.

I think you're missing the fact that I'm comparing it directly to how well these same devices charged the 4. So they're clearly not defective so much as the 5's requirements have changed completely. And USB 1.0 (I think you mean 1.1) isn't relevant here, as I'm not charging off a computer, I'm charging off a wall and/or car adapter. But sounds like we had very different experiences with the 4. I could charge my 4 off my Monoprice pocket battery in crazy fast time, and my phone was always full by the time I reached my destination in the car, even with Waze running (once I figured out I couldn't use the long cable I was using initially).

Exactly. That's why I was surprised. There's no way it SHOULD be this much slower. Yes, I can see percentage adjusting slightly for the larger battery, but that's why I'm going by mA input instead, and my 4 was getting WAY better in the car. Although I don't think it ever got the 1.2 I'm getting with the Monoprice wall combo, so THAT's impressive. Now if I can just get that in my car without the RF interference and I can call it a day.

Well then your either have defective hardware or currentwidget just doesn't work. As I inferred hard to tell w/o proper tools.

Oops, multiple responses and replied to incorrect one, but really if your recharge rate is that much lower v. n4 I'd say that your chargers or n5 are defective. It's going to take longer to charge the n5 obviously, and I have no idea what the max draw either can achieve as I've been strictly using inductive charging w/max 1A supply(as per Qi spec)... n5 takes longer to charge than n4, but thats to be expected by batt cap(and wear(decreased cap) of n4 batt)...
Subjectively, the n5 takes longer to charge, but not that much longer that I've noticed, again batt cap, etc. so...
Both USB/AC adapter chargers I know supply a max of 1.2A...

Neither I think, we don't need any mA values to see that something is wrong, android is telling us that it thinks that it's connected to a usb port while it isn't.
Of course if we would want to measure exact mA values we would need a different equipment, for cable comparisions in order to see a tendency, the values from the charge IC should be good enough.(IMO)

Well it looks like the N5 has a very low tolerance for AC/USB detection, I'm sure that neither his chargers or Phone are defective, the chargers just aren't 100%in the spec which is obviously enough. I'm sure that the stock charger would be fine.

Clearly neither is the case from my testing. The N5 charges beautifully off of the right combination of chargers, and all of those chargers charged the N4 beautifully. Neither is defective, but the N5 apparently has a different tolerance requirement than the N4.
Really, as opposed to anything being defective, it sounds more like a design flaw in the N5. It's WAY too picky about its power sources.
Mine charged REALLY slow the first day and that night. It also drained really quickly during that same time. I am now on my third day and it has long battery life plus it charged about 20% in 30 minutes on a car charger. Seems quicker than my S3.
Hi,
Wanted your thoughts and opinions on charging speeds. I've never actually timed how long it takes to charge. i leave it overnight and it's ready when i wake up.
When i plug the phone into the charger, it flashes up slow charging for 2 seconds then disappears. which got me wondering how much it's actually using.
i used to use Current Widget app on my Samsung S3 which told me exactly how much current the phone was taking from the charger. typically it was 1A via AC/mains and 499mA from a PC. Plugged in to AC, I could play a power hungry game and it would still charge the phone at a good rate.
The LG kernel doesn't like these apps - the mA value is all over the place but it's typically <500mA displayed.
I could buy a USB ammeter to work out how much the USB charger is supplying but do you have any other methods of finding out? Do you know what your phone uses?
at home, i use a Xtrememac dual USB charger, 2x 2.1A output with a shielded 3M USB cable. for those wondering, it's the same regardless what cable i use. Have also tried with generic usb chargers, iPad chargers and official and OEM cables from LG and various other manufacturers. Have also used a data-shorted USB cable from PC which is the same result.
I haven't tried the LG charger yet (mainly as it's a 2 flat-pin plug and i don't know where i put the box) but i think i recall it being a 1.8A charger.
I use an application called "charger report" which can display current consumption and Xtar "USB detector" device. They both show the same numbers. But Xtar USB detector can detect voltage of a charger. The charging current of LG g pro 2 is 1.4-1.5A when the smartphone is not used and higher when I use it. Using USB detector I found out that this smartphone can charge with maximum current a charger can give only if the charger's voltage is 5.3v. So it chargers at full speed with original charger and two other chargers I have: a charger from my Lenovo s6000 (2A 5.4V) and from my Asus t100 (2A 5.3V).
i tried that app too and got the same results as with Current Widget.
i'll buy a "usb detector". thanks.
I forgot to mention that it take approximately two hours for charging indicator to reach 100% when the smartphone reports that it fully charged. And it's necessary to left it connected to a charger for ten to twenty minutes to be really fully charged. Otherwise charging indicator will soon drop to 90%. One can tell if a smartphone is still charging by touching a charger or by looking at current consumption: a charger would be warm and current would be higher than 200mA.
Is the GP2 Quick Charge (1 or 2) enabled? I can't read anything about it other than it's in Snapdragon chipsets. Not sure if it can be disabled or not.

The Snapdragon 800,801 and 805 is for Quick Charge 2.0
The Snapdragon 600 for 1.0
ok, does anyone use a Quick Charger with their GP2? is it noticeably faster?

Hey ray-lee!
I just bought this phone and as it seems it could get someday similar problems as my former phone the Galaxy Note 2.
That phone has had problems with charger and cable also. I had to buy another set of charger and cable since the original ones gave up a few months after i purchased the phone (it was used). The cable managed only 500mA wich is very slow for a battery that strong. One night was once not enough to charge my phone from 30% to 100%. As it seems it is problematic to manufacture cables, that can hold up and continually grant the 1,8 A that would charge our device in just 2 hours. I read somewhere that the G Pro 2 is one of 5 devices that has blazing fast speeds on charging the battery. If you handle the cables with caution hopefully you will not encounter problems. If so my guess is, that you will have a hard time in finding a cable that can hold up. Sadly the stock cables are always more expensive. I do not get it, why companies dont build travel adapters that only charge ur phones built solid with sturdy cables to ensure the transmission of high currents. That way with charger + usb cable is just stupid, even when tis is an all in one solution.
I like this phone very much and i hope, that the cables will not be that sloppy as the cables that Samsung had/ still has. With Current Widget i get readings around 1500 mA (1,5 A) when connected to the stock charger. And yes the LG Charger is an 1,8 A one. I have also flat pins, but received an adapter to be able to connect it in Hugary.
Just sharing thoughts here, that will maybe helpful to someone...
:highfive:

i "think" as long as device has snapdragon it is Quick Charge enabled
I use the "Charging Report" app on my phone, and it reports proper values.
(Around 1500mAh with the LG charger, and around 1600mAh with the 2.0A Samsung charger.)
If your phone is charging slowly, check the CABLE. Cable can broke too.
(Many people complain about their Samsung charging cables, because they just stop delivering power after a while and just charge the device slowly.)
Anyone tried Quick charge 2.0?? https://www.qualcomm.com/products/snapdragon/quick-charge

How long does it charge from 0-50 from50-100 from 0-100?
There aren't many chargers out there. and the ones that are, are usually US 2 pin. I need a UK 3 pin or travel charger (changeable pins) really.

To achieve full charging speeds, a Quick Charge 2.0 enabled device must be paired with a Quick Charge 2.0 certified adapter
I picked up a T-Mobile V20 2 days ago. Rooted it the same night, and tested out a few chargers I had laying around to make sure the ones I had, along with cables, worked properly after having most everything not work properly with my Pixel XL.
The stock charger would not charge my phone at more than 3 watts (but I never touched the stock charger until I started noticing the issue).
A Samsung QC charger, with any cable, would not charge my phone more than 9 watts.
An Anker PowerPort+ 1, Type C, QC 3.0 charger, with any cable (to include Anker cables and the Pixel XL OEM cable), will not charge over 12 watts.
Absolutely NONE of my QC 3.0 car chargers register as "fast charging" - these include an iVoler Type C and USB A, Anker USB A, Tronsmart Type C, with various cables. A standard cabled Type C charger from i-Orange does not say "fast charging," but seems to be charging at 5V/3A as it is MUCH faster than all the others.
The ONLY charger that is fast charging my phone is the Pixel XL OEM charger. Measured at the wall, it has peaked at 19.2 watts.
I'm really confused. I don't know if my QC 3.0 has been defective since I got the phone, or if plugging my phone into the USB PD Pixel XL charger somehow screwed things up...
Does anyone have any ideas here?
All my old QC chargers work and I'm currently using the note 7 oem one atm as it does not get as hot (charger not phone) as the LG oem one under load. What does the app ampere say your getting?
It takes a while, try a very low battery and give it 10 minutes or more screen off, must be cool too
I got an existing aukey qc 2.0 fast charging fine while using a Samsung adaptive fast charger also fine, I am waiting for my qc 3.0 aukey one to be arrived possibly tomorrow to see if I could charge faster and lower temperature than my existing ones, I cannot check the watts though
My phone is either defective (not surprising given LG's GARBAGE quality control) or the software has somehow screwed up from root, etc. (highly unlikely as I am the only one with an issue).
With that said, I made an interesting discovery. My phone, using USB Power Delivery, charges much faster than my girlfriend's, using QuickCharge 2.0 or 3.0. I tested this 2 times from 5% battery on both phones. I tested this with a QC 3.0 car charger and the OEM QC 2.0 charger. The difference is substantial... first test was about 40 minutes. My phone was near 80%, hers was at 55%. The 2nd test was only 15 minutes. Mine was near 40%, hers only 27%.

Don't remember what Ampere says, but it was <500mA. Also, I used a USB current meter. It hovered around 5V/0.5A no matter what charger I used. I don't have a Type C/Power Delivery current meter, so I couldn't test those chargers... but USB PD is CLEARLY working very well on the V20. Much better than QC.

It does not take awhile - takes <5 seconds to begin the QuickCharge process. Phone does not need a very low battery - will show fast charging regardless of the %. Does not need to be cool - fast charging is shown when the QC handshake occurs - not based on actual charging current. My girlfriend also has a V20. Every charger I tested with mine (which did not work), successfully QuickCharges hers.
Are you you using 56 k resistor cables?plus being rooted a kernel app would have a section to disable fast charge or enable it. Most devs disables by default. So if using custom kernel something to look in to. As I doubt there is anything wrong with your phone.

Just got the aukey PA-T15 qc 3.0 seems fast charging fine though I have no time for a 0% to 100% test yet

All of my cables are good. No custom kernel, and I've never seen a dev disable fast charging by default... that would be very unpopular.
Anyway, it seems that LG's recent phones, to include the G5 and V20, are actually supporting both QC 3.0 and USB PD. This is also probably why QC 3.0 chargers that use Type C do not work (the Anker PowerPort+ 1 in my case). On a C to C connection, with USB PD present, USB PD will take precedence over QC 3.0 (since QC 3.0 is illegal with C to C anyway). But that still doesn't explain why my phone doesn't QC via USB A to C... so I'll chalk it up to LG's garbage quality control.
I'm glad it worked out this way. USB PD charges my phone WAY faster than QC 3.0 charges my girlfriend's V20. So I would suggest you all dump QC 3.0 (because it's non-compliant to anyway) and grab USB PD equipment since it's the way of the future anyway.
I'm starting to think that there's something wrong with the way V20 handles QC 3.0. I'm in a somewhat similar situation with you, tested three different QC 3.0 using almost 10 different A->C cable (including the OEM cable) and none of them would deliver QC 3.0 speed. (I just came in a from Axon 7 and the difference between charging speed is night and day).
Additionally, I wish there's an app to properly identify what's going on during charging.
Using the built-in battery test from Service mode (see screenshot), it always says that I'm on QC 2.0 whenever I'm charging using QC 3.0 chargers.
My unit (LG-H990DS) is charging very quick though.
Using stock charger & cable, charging time is very consistent from 0 to 100%. 95 mins is all it takes.

The stock charger that LG sent with the V20 is actually a QC2.0 unit.
and with QC3.0, it'll take you less than an hour to fully charge.

Both results are similar.
So now LG V20 under utilise the Aukey QC3.0?

I can't say for sure, because I have no way to get a baseline on how fast a QC 3.0 charger charge at the correct QC3.0 rate on the V20....
At least according to the battery test from the service mode menu, none of my QC3.0 chargers are being recognized as QC3....and it definitely doesn't charge as fast as 3.0 based on my previous experience with axon 7.
on The Axon 7, I can still be playing Mobius FF (which is very battery intensive) and still charging up at about 1% per minute.
I'm pretty sure our phone doesn't have QC3 as I just mentioned in another thread. I'm like.. 97% sure? I remember reading early on that it was QC2, and a blend of LG that got it a little more robust than that. I'm not sure all of what's required for QC3 to work, obviously the 820 SOC supports it, but, not sure why I read that we don't have QC3.,

Yeah, I'm starting to believe that's the case now. I just updated the thread btway, now they're saying that 3.0 isn't enabled by LG.
Not sure this is the case of Tmo employee not knowing their sh*t or what.

FWIW, I have a couple of Aukey chargers. One is QC2, and one is QC3. They both "fast-charge" my phone, but I don't think I get the fastest charge on anything but the LG adapter. Usually it's fast enough for me, but I guess if I was 10-15% left, and I needed 100% in less than an hour, it might not happen.
I just picked up a US996 (Unlocked V20)... and found this site while trying to make a decision on buying new chargers, cables, etc.
I opened a chat with LG to ask them if the V20 supports USB-PD... and I got this response:
Merwin
Not that we can verify, Ryan we because we have not tested it. I highly suggest you to use the OEM charger of the V20.
Click to expand...
Click to collapse
So... no help from Merwin @ LG. It seems they're not allowed to comment on it, and can only recommend the OEM charger. I was unaware that it was only QC2.0, according to the testing above.
Has anyone done more testing since? Can I buy a USB-PD charger and C-to-C cable? Should I avoid QC3.0?
Thanks
I'm interested in this as well having bought 2 QC3 chargers and neither charge my phone as fast as QC3 advertises.
I have used my brothers stock Nexus 6p charger from Google and the times are about equal to my QC3 chargers I bought
I'm using a Samsung QC 2.0 charger for mine:
https://www.amazon.com/Samsung-EP-TA20JWE-Travel-Charger-Devices/dp/B00TEUVEIO
I use it because I lost the LG one. It does quick charge but I can't measure the rate in the service menu. It just stays blank.
This is real easy, it happens with qc 3 on my v20 and s8+
The phone does not quick charge when the battery is warm or when the screen is on. Its really that simple. You can get faster charge times using a qc 2.0 charger or a dumb 18 watt adapter. Neither one is as picky about sending power to a warm battery, but your batteries life will be shorter than it was designed to be.
QC 3 will charge a cold empty battery faster, but in real life, it will preserve your battery over fast charging the phone.
An answer in Lenovo's support forums says the G5 does not support Turbo Power, but it comes with a 10W rapid charger. The problem that here in Brazil not even this 10w charger gets shlpped with the phone, neither can I find it for sale, so I'm thinking about getting a 15W Turbo Power charger, does anyone knows if it'll charge the G5 (25W and above are reportedly not working with the G5)
It won't work, But you'll get fast charge tho (NOT TurboCharge, which is even faster. Just standart fast charge)

Ok, if you do it, that'll hilp a lot, since moto G5 came with this standard 2A charges.
I bought my Moto G5 in Brazil near the launch date, it did come with the 10 W charger (5V-2A, W = V x A, do the math). As far as I know, Snapdragon 430 support Quick Charge 3.0. I bought a ROCK charger with Quick Charge 3.0, just waiting for it to arrive from Aliexpress, should work just fine.

Well, I didn't know that this would result in 10W. Anyways, as far as I know the moto G5 doesn't support Turbo/Quick charge, despite using the Snapdragon 430. I say thay because none of the TurboPower chargers in Motorola's website cites the G5 as supported (only G5+/G5S), in addition, I read many reports in Lenovo's official forum repporting it doesn't support Quick/Turbo Charge, like here: https://forums.lenovo.com/t5/Moto-G...g-with-Qualcomm-quick-charge-3-0/td-p/3828209
In other words, a 15W charger is not supposed to provide great advantages over the regular charger that came with it.
Anyways, thanks for showing me a 5v-2a equals 10w, I googled and confirmed it.

You are welcome.
To be honest I have been using the Quick Charger but can confirm if it's working or not. I usually just plug the phone before going to sleep, when I wake up it's already 100% . I will search if there's anything available to detect if it's using the quick charge or not.
Did it work?
I'm using my wife's charger from her G4+ and it seems not boost the charger at all. It takes the same time with my own charger. Normally, batteries got a regulator that protect the battery from being overpowered and, maybe, exploded. So, if it was setted to 2A max it won't work anyway. Also, the official charger detects, through USB interface, if the device support Boosted Charging before sending 3A. If you wanna save your money, my advice is don't buy it.
Moto G5 doesn't support Qualcomm 2.0 or 3.0 which charge at 9V or 12V. My original charger used to charge at 5.2V and up to 1.5A, but it doesn't anymore, now doesn't go over 5.0V. Very difficult to charge when powered on when normal charger only manages about 0.6A . Also have problem with portable battery packs, best option is to connect external battery when full, and it just about stops internal battery falling. Maybe the connector wearing out, have tried different cables....

Sometimes it can be as simple as a tiny piece of pocket lint/crud in the USB charging port. You can buy cans of compressed air to blow them out same as used on Camera lens or check with magnifying glass and then a toothpick with care to clean anything found out.

Blast from past on old phone! The usb port eventually failed completely, fortunately the little board is easy to replace, but the replacement board only lasted a few months. I still have the phone as a spare and charge the removable battery out of the phone.
