Charging question! (CHOETECH Charger) - Nexus 6P Accessories

Hello,
I have a weird issue. Let me explain:
Phone: Nexus 6p
Cable: USB Type-C to Type-C google OEM
Charger 1: Original google OEM
Charger 2: CHOETECH Charger (Link)
Charger 3: Vinsic High Speed Quick Car Charger (Link)
Issue is:
Charger 1: Original Charger works great phone battery lasts like 1 and 1/2 days (one day and a half)
Charger 2: Charges well to 100% no big difference from original one but phone battery always last way less (like barely 1 day, not even 1 full day)
Charger 3: Charges well to 100% takes more time then original one and phone battery always last way less (like barely 1 day, not even 1 full day)
All chargers are used with the OEM cable and the results are observed on a period of more then 4 months. At first I thought is the new cable I used but after try with OEM cable same result, I'm not so sure anymore.
Can anyone explain what is going on? What original charger has that 3rd party chargers does not? Anyone have the same issue?
P.S. This is not about any differences in utilization of the phone when charged with 3rd party chargers. I tested this a very long period of time, this really happens.

I don't have an answer for you but I have noticed that different chargers produce different battery life results. Doesn't make since, but there's definitely a difference between chargers.

Well to prove your point : data. Engineers like data. Plot a data map.
But I haven't noticed this effect. The choetech doesn't charge at a "true" 3 amps like the oem, but very very close. Both of those chargers are very good, from my experience.

Okay I am open to any suggestions, what else could be the cause of this happening?

Not that big!

I would say, it is the perception issue and not the real one: it is hard to believe that 100% charge resulted from different chargers would last with any difference in lab conditions. Thus, I speculate, that the issue comes from different (not sure that apparent) actual usage of the phone.

The chargers don't monitor the charge level, the phone does. The phone can't tell the difference between chargers, other than what charging rates they support.
If you were charging a removable battery where the charger controlled the charge level, I could see this happening.

I'll test more and maybe come back with some results!

CHOETECH Charger has QC 2.0 this is the reason phone battery charges but not right way!
Thanks for help!

Full power charging dock?

I want a charging dock for my S4 that will feed the phone the full amount of power that it can take, for quickest charging. I believe the stock charger that came with it supplies 2 amps.
I also would like said charger to have a slot for charging a spare battery at the same time.
All the charging docks I've found so far only claim to supply 1 amp to the phone, or less. Except one dock I found that did say it outputs 1.6 amps.
Does anybody know of a charging dock that will supply the full 2 amps? How about one that also has a slot for charging a spare battery?
Thanks.

Would you like it to serve you eggs and ham as well?
Damn.. you are really asking for so much and not nearly searching for it yourself enough if that makes sense.
There are charging docks that have a battery charger slot as well. They have a microusb port for power input. You can use a 2A charger with it and I believe it should be charging the phone at 2A but only when you're not charging the spare battery. I do not have the link as I saw it while randomly browsing through S4 docks on eBay. It's easy enough to find.
No, thanks. If it could cook my eggs and ham, it would be too bulky. LOL!
I looked through roughly 150 listing on eBay. I saw a whole bunch that said 1A output. And a few that were 700 mA, and at least one that was 500 mA. And exactly one model, available from a few different vendors, that said 1.6A output.
I did not see any that said 2A output. Just because the wall wart can supply as much as 2 amps, doesn't mean the charger will actually output that much to the phone.

My advice, is you should risk it.
If you're looking a product with such precise specs, I'm afraid you're not going to find it.
I messaged several different ebay sellers last night to ask if their charger is really only 1A and if they'll be having a 2A model. So far, I've gotten responses from 3 or 4. All of them have said sorry, we only have 1A. Please note, it will charge more slowly.
Update info. This may be old news to many, but here it is.
I had an online chat with a Supervisor at Seidio this morning. Their website has 2 charging docks for the S4 and neither lists charging output.
They told me that the dock will output whatever the wall adapter supplies. The charging dock is a passthrough. So, if I use the stock OEM charger with the Seidio dock, my phone will (allegedly) still receive 2A of charging current.
This may have been intuitively obvious to some, but it wasn't to me.
So, my quest is now much easier. Apparently, the docks I looked at on eBay that say 1A charging output must say so because the supplied wall adapter only provides 1A. And ones that say that but don't include the AC adapter are just making an assumption about that AC adapter you'll use.
BUT, though the phone charging port may be a passthrough, the slot for charging a second battery (on docks that offer that) would have the charging logic/circuitry built into the dock, so that could still be limited to 1A or less. At least, that's what I think. Could be wrong.
Regardless, i ordered a cheap dual charging dock off eBay that should be here by Friday. Using Galaxy Charging Current (a free app in the Play store), my phone shows 1900 mA charging current when plugged into the OEM charger directly. After I get the dock I ordered, I'll test that and report back.
If the dock will charge the phone at full speed, I can live with the spare battery being charged more slowly.

It's NOT a dock but a charger and it does come with an OEM spare battery. It charges a battery from 0 to 100% in about 4 hours, which is faster than your phone would deplete a battery, even when gaming. Paid $47, no shipping from Amazon
I see the price have changed a bit meanwhile but it's worth it if they still don't charge any shipping. Ships directly from Korea (made in Korea - both, charger and battery)

Hope it works out. The dock i ordered from seidio for my evo 3d did not charge at full power with the supplied adapter. I used a diff cable and power source and the results were better, but still not very good. Most nights I simply removed the cable and plugged the phone directly to it bypassing the dock, kind of defeated the purpose. I hope to find one that keeps the S4 charged.
Well, I received my eBay dock today, 2 days early. It is this one:
http://www.ebay.com/itm/111066155507?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
And when I plug it in and put the phone in it, I get a message that the connected charger is not compatible with this phone. And the phone shows a red X over the battery icon in the notification bar, and doesn't charge at all.
I tried it using the OEM charger and cable, the cable that came with the dock, and I also tried both cables using my OEM charger that came with my Note 10.1 tablet.
Exactly one time, when I put the phone into the dock, it didn't display a message and Galaxy Charging Current (app in Play) showed that it was charging at 1900 mA. But, several times before, and every time after that, it just displayed the message and wouldn't charge at all.

I've seen that and that's a big "no way". My normal deal is, if I run out of battery, it's because I'm out and about. Traveling on a plane. Riding my motorcycle. Whatever. Situations where I don't have the option to plug in. So, I swap batteries on the go and the charge when I get to where I'm going.
This charger on Amazon would require me to carry it, plus my phone charger, plus an additional phone charger to run the separate battery charger. If I were just going to share my phone charger between the phone and the separate charger, I would rather just have the phone on the charger and, when it's fully charged, swap batteries, to charge the next one - not swap the charger cable over to the separate battery charger.
if I were going to go the route of a separate battery charger, I would spend $7 or so on eBay on one of the ones that has a flip-out plug built in and plugs right into the wall. That is the kind I have been using for a while to charge my Rezound batteries when traveling.
The biggest problem with those is that they charge the battery at something like 350mA. Ridiculously slow!

...buddy, that's EXACTLY what this is. It simply gives you the option of charging another OEM battery (in the charger NOT in the phone) BEFORE you go out and about and then swap them as you need.
NO, it's NOT charging as slow as you suggest. They use a technology called direct charge which means that it draws as much (or as little) as your wall plug allows it. In other words if you plug it in the PC USB, then yes, you'll have to wait until you grow a nice thick beard, but if you plug it in your original 2A charger, it'll charge the battery from 0-100% in about 4 hours or less.

Absolutely NOT true:
1. You ONLY need to carry the charger if you plan on recharging the depleted battery BEFORE doing another swap - that's at least 12-15 hours on EXTENSIVELY using BOTH batteries - that's 12-15 hours screen on!!!
2. ONE phone charger can be used on either/or - you'll never have to charge them both in the same time (that's the idea with swapping the batteries, right?)

Up to you buddy, but usually you get what you pay for. The one I suggested comes with an OEM battery. I always suggest using this method over any battery pack as an OEM battery will ALWAYS give you just as much "juice" (this translates into running time) as the...yeah, you guessed it, the Original Equipment Manufacturer's battery. Although the battery packs manufacturers, they all claim huge capacities and running times, this mostly never holds true to the advertised specifications. It's called marketing

I don't think you're getting me. The point is, I get to the end of the day and I need to charge my phone AND the battery I used up. In order to charge both at the same time, using this Samsung separate battery case/charger, I would have to have 2 actual chargers. One to attach to my phone, to charge that battery, and one to attach to the separate case/charger.
Get it now?
More detailed:
- I start the day with 2 fully charged batteries. One is in the phone.
- I ride my motorcycle all day, streaming music via Bluetooth to my helmet, and talking on the phone while I'm riding.
- Before I'm done riding for the day, my battery dies, so I swap it.
- I continue riding, etc.
- I get where I'm going and I'm ready to go to bed.
- I now have a dead battery in one hand and phone with a partly depleted battery in the other hand. I want them to both charge while I'm sleeping.
This separate case/charger does not help me.

No offense, but I believe you don't get it. You say: "I need to charge my phone AND the battery". I should ask you then, do you still need to charge your phone and the BATTERIES (this is the plural, meaning two or more) should you go by my suggestion?
Either, or, if you're such a heavy user and you find yourself at the end of the day with 2 or more depleted batteries on a regular basis, then this becomes even more handy - admittedly, yes, using a second wall plug...or, again, if you're such a heavy user, then buy a 3rd OEM battery - case solved. (1 charger, 2 extra batteries, 1 USB cable, 1 wall plug)

You obviously didn't read my whole last post. Otherwise, you would understand that saying "I need to charge my phone AND the battery" is a short way of saying "I need to charge the battery that's in my phone (but not totally dead yet) AND the battery that I depleted earlier in the day."
And if I added a 3rd OEM battery (which you would also see that there is no need for, if you read my whole previous post), it still would not change the fact that, at the end of the day, I have 2 batteries I need to charge and only 1 wall charger to use. So, the separate case/charger still does not help.
If I charge the battery in my phone and then want to use my one and only wall charger to charge the battery that's in the case/charger, I may as well just swap the batteries and charge the second battery in my phone. Thus, I would save running down the battery that's in my phone while the other battery is charging in the case/charger AND I would save spending $50 on the case/charger when I just used my coupon last night and got an OEM battery straight from Samsung for only $20.

OK, now I did get what you were saying (admittedly, I didn't read the whole post initially) but I still believe that carrying a second set (wall charger + USB cable) would render a better overall usage time without compromising on convenience or quality (again, due to using a certified OEM battery). Think about it, the only "compromise" you're making is carrying another set - which is nothing, both in terms of money and used space/volume.
So, your on-the-go package would consist of: 1 Samsung charger, 1 extra battery and 2 sets of wall chargers/USB cables.
Now, we're getting somewhere!
Your alternative would cost me something like $70 for the case/charger (w/battery) plus a second AC adapter.
My alternative will cost me less than $30. $20 that I already spent on a second OEM battery, plus less than $10 for a wall charger like this:
http://www.ebay.com/itm/Charging-Cr...l_Phone_PDA_Chargers&var=&hash=item27d35082af
And I have less "pieces" to carry around.
Of course, the cheap wall charger won't charge the battery as quickly. But, I have been using a charger just like that for my Rezound batteries for a while now and it always seems to manage to get the job done overnight.
However, the PREFERRED solution is what I asked about in my OP in this thread. I want a dock that will supply full power to the phone and a spare battery at the same time. As I posted later in this thread, it now seems that most any charging dock should supply full power to the phone (as long as the AC adapter is providing 2A). Those docks still won't probably give full power to charge the spare battery, but I can live with that. So, with a dock like that, I would carry the same number of "pieces", but I'd have the advantage of having a dock to prop my phone up next to the bed, so I can see it.

I can 100% attest to this NOT being true. I have my OEM Samsung S4 2A charger hooked up to my Seidio Innodock Jr. at it receives a MAX of 1020mA. Yes, I realize it isn't the exact charger you are looking for since it doesn't have the spare battery compartment, but Seidio is NOT being truthful to you when they say that it is "a passthrough" dock. Just a heads up!

What are you using to determine your max of 1020A? Galaxy Charging Current? Battery Monitor Widget?

I have both and they do not display the same data. As far as I can tell, GCC shows the actual full incoming current. OTOH, BMW shows the current being used to charge the battery.
When I plug in my OEM charger, GCC shows 1900. But, if the screen is using 100 and other stuff running is using another 100, the BMW would only show 1700.
So, as far as your post about the Innodock, if GCC shows 1020, then that's what I would believe. But, if it's BMW that's telling you 1020, then that could simply be because there is other stuff using almost 900 mA of current.
For the record, I looked through my BMW Usage log from last night when my phone was on the charger. The log shows every 5 minutes, I think. It only had one log entry where it showed 1992. All the rest were in the 1500 - 1600 range or less. And the phone screen was off that whole time.

[Q] Terrible charge rate?

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:

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.

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)

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...
...(from last so) ask for a replacement n5, after they've been replacing them for a single dead pixel...

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.

Discharging while using Navigation

Hey Guys,
So I was recently on a trip this weekend and was using Navigation on my Nexus 5 for a 4 hour drive. I had noticed though after a short while that while I had my Nexus 5 plugged into a charger it was still continuing to drain battery.
With my Galaxy Nexus in the past I was able to run Navigation / Music / Etc.. all whilst still charging so it came as a disappointment when I saw this.
I made sure that I was charging on (AC) mode and it still continued to fall, albeit a little slower than (USB) mode though. When I went to the battery usage navigation had taken up about 59% of the battery drain, I was surprised because I though it would have been the screen but that was only like 14% of the battery drain.
Anyone else run into this issue?
Check the Amp output on the charger. Anything less than 1A will not charge the phone while in use.
I had the exact opposite issue with my G-Nex, the "rapid" charger I was using only output 550mAh as opposed to the 1A that is required to charge while in use. I don't believe it is an issue with the phone, it's probably just the charger. $10 to $20 will get you a nice, reliable one with the proper output, and possibly an additional USB port.
Hopefully this helps
Don't buy cheap car chargers, just not enough power. I use a Verizon car charger that has an extra USB port for charging another device and it charges while the device is in use.
Thanks for the input guys, unfortunately the charger was 1 amp that I was using. I do have another car charger that I use and none of them are the cheap USB ones. I guess I'll have to do some more testing with the other car charger that I have.
I was just mainly concerned, not if there was something wrong with the phone, but with the fact that even when charging in AC it wouldn't keep up with navigation's wear on the battery usage.
Thought I would update to confirm that my Galaxy Nexus car dock charger charged it extremely well after testing while navigating.
Definitely was the other one I was using.
When you switched chargers did you happen to also use a different cable? I couldn't get any of three different chargers that I tried to keep up with the GPS battery drain. Then I realized I was using the same cable with all 3 chargers. The problem was that the cable kept the phone in DC charging mode at nothing more than 0.5 amps. I bought this fast charging cable on Amazon and now I actually gain battery percentage even while using my GPS full time.

[Q] Charging w/ alternate chargers... a risk?

I bought a brand-new Nexus 5 a few weeks ago. However it came with a 0.85A wall charger which is LG branded... and some 'generic' cable that was included too. Used it twice, but it took around 8-10 hours just to charge 80% of it. I plugged my old Galaxy Ace USB cable to the LG charger and it reduced to two and a half hours, same with my alternate charger from the aforementioned phone (5.0V + 0.7A).
But this led me to a question: Is using alternate chargers with < 1.2A of output a risky way to charge my Nexus 5 battery? I saw somewhere that it might even damage the circuit board (a rare case) and I'm a bit worried about it.
Using a charger with a lower amperage output will take longer for the phone to charge. Also, using a cheaper cable will also lengthen the charge time as the cable can pass the full amount of power to the phone. This has been my experience with using oem cables vs dolls store cables me chargers.

But... Will a Samsung wall charger with 0.7A of output damage my phone if I use it as my main charger? Because I also have a chinaphone which came with a bad charger and the Samsung one works fine.
No, the Samsung charger @ 0.7A will not damage the phone. I use a 1.0 A and 2.0 A Samsung charger with my N5 and it has been fine for months and months.
With the Samsung 0.7A charger, battery gets charged in 2:10 hours. I still don't understand it since I came from a low-end Samsung device which could complete its charge in about three hours (and that one had a 1500mAh battery...)
This is a tricky question, no doubt about it.
IMO, the cable quality is way more important than the current output (0.7 A, 0.85 A, etc).
I have a Samsung S4 charger with its cable (it seems very well built and it's thicker than other cables) and my N5 goes from 10% to fully charged in less than 3 hours.
Funny facts - happened to me:
- I had a very cheap cable (probably from China) that came with a battery bank. Surprisingly, it was the fastest way to charge my phone - reached almost 2.0 A. Later I found the trick: this cable doesn't have all the four wires, it only had two (positive and negative, without the data wires). I believe the data wires is used to perform some kind of amperage control; without it, no control was done and led to a very fast (probably dangerous) charging. I don't use this cable anymore, chances are that this nasty cable screwed up my notebook battery
- My N5 is almost two years old. Recently I had a problem with the Power button, the internal contact of the switch on the board was stuck 'pressed' and this led my phone to an endlessly force-reboot. I discovered this behavior after some google search and one of the possible causes of it is exactly the usage of a non-default / faster charger, it said that this could melt something - SOURCE
It makes sense, but I can't confirm this. I was able to fix this by smashing the phone on a table a few times (lol) and I'm still using a non-default charger
Can anyone confirm / say something about these facts?
For those who wants to see the diference between cables and chargers, give this app a try:
Play Store - Ampere
This app is a current meter, I use it on a regular basis and it is pretty reliable - the dev it's a XDA member and this app can be discussed here
Hope this helps!
You can not harm a phone with a 5 volt charger. The phone takes the amps it needs. More is better than less. I use 2 amp, 5 volt ones. As has been said the usb cable is the key thing. The better quality the better charge.

Charging Pixel with old phone chargers

As I'm sure is the case for many of you, I have a ton of typical USB chargers around the house, which supply anywhere from 0.8A to 1.5A output. Going with the assumption that I don't care how long it takes to charge, is there any risk with using the USB C-A cable that came with my pixel and plugging into any of those old USB chargers? They should all work, right? Just as different speeds depending on the output current?
I am not an expert, but from my research into the safety of USB-A to USB-C cables, the "risk" will generally come as a result of purchasing a cheap cable that does not have the appropriate (56k) resistor. The cable that came directly from google has the appropriate resistor and is not low quality, so it will be safe to plug into any functioning USB port (either on your computer or a charger).
That being said, if you have a malfunctioning charger, or there is power surge etc., that is an "act of god" and what happens happens
You may actually be better off using these old chargers if they work correctly. The slower you charge your phone, the better it is for the longevity (years) of your battery.
Yeah, that is why I didn't care about charging speed. For plugging it in next to my bed each night, I figure slower is better. However, I just received a mini USB to USB C from Amazon, and used that to plug my pixel in last night to a 1a charger. And while the phone did say charging over USB, it didn't gain any battery overnight and instead continued to discharge until I woke up in the morning. Is anyone else seeing anything like that?
Not trying to be mean or name call but I personally think you all are crazy. Buying a $700 phone and using a cheap charger that could have the risk to break your phone. Especially if you know better. Honestly, spending the $30-$40 from a charger from Google or an approved charger is just smart for the long term and not risk losing $700. Just my 2 cents. I did the same for the car charger.
Sure, I hear your point. But honestly I know that it is better for the battery to charge slower, so I would rather use a low power charger next to my bed each night, and only use the included quick charger when I need a quick top-off.

Have to consider 2 points since there are so many inaccuracies about this subject:
1) Inadequate chargers with insufficient output cause batteries to become overheated, consequently reduce battery charging cycles. Smart batteries are not adversely affected by certified quick chargers.
2) Turbo chargers do not "top off". When a battery gets to around 80%, the appropriate charger begins its slower charging as to not overload it. Once at 100%, charging stops, and the maintenance process begins. As battery level drops to around 97.6%, trickle charging begins.
In sum, a certified, OEM-equivalent quick charger, even with higher output would not damage batteries.
The phone supports most standards however usb c and Qualcomm quick charge are not compatible and you fall back to 5v 3 amp at best. Make sure to fully insert the cable into the phone. It has to click. I've accidently not charged overnight that way.
I've got a bunch of turbo chargers that I've accumulated over the years. Using a non-[manufacturer of current phone] charger has never damaged my phone. I just bought a 10 pack of USB C adapters and popped one on every charger so I can continue using my old ones. No issues yet and I don't anticipate any.

Sure, you can use non-oem chargers. That's not the problem. Issues only potentially arise when the chargers do not provide adequate output, or their "smart" capabilities are not up to specs. I use all kinds of chargers bought at Verizon, Best Buy, etc. I also use Amazon chargers as long as they're not too far off OEM requirements. Also, people don't think about the importance of a good, thick cable.

Many will say no big deal. However, I'd say let's hear it from the horse's mouth. Here's Google engineer Benson Leung https://plus.google.com/+BensonLeung/posts/cEvVQLXhyRX. You be the judge.
Bottom line, to answer your question, no, quick charging methodology used by Samsung and Motorola is not supported by the Pixel. Your phone will charge at a slower rate. Will it damage the phone in the long run? Likely not. Well, I'll let you guys test for me.
