I know some people use chargers other than the stock HTC charger...
does using a different charger with lower or higher milliamp ratings make a difference or hurt the battery in any way?
Dont know anything about damage, wouldnt think so.
In my experience, my HTC desire has two modes of charging USB (500mA) or AC (1A).
If the two middle pins of the usb cable are shorted it assumes its connected to an ac charger so it pulls 1A. This is due to the max rating of a pc usb connection being 500mA, so everytime it thinks its connected to a pc it wont draw too much and damage your pc motherboard etc.
Now coming back to your question, some chargers have their pins shorted, some not. Apart from longer charging times, the only real issue is for car chargers, where some poeple have found that if you use one that sets the phone to USB mode, and you are running lots of thing like nav software etc, the battery will still drain even with the charger connected. ie its using more juice than its taking.
Personally I have charged my desire with many USB devices, like ipod chargers, etc etc with no ill effect. I found out thtat my ipod WONT charge from the HTC charger, whereas my phone would happily charge from the apple charger. Prob due to some usual Apple rubbish about who gets the accessory money, so for travelling I just take the Apple charger now.

Both my kid's iPod 3G charge from their Htc chargers just fine so I'm not sure why yours wont. I bought a dock last week for the phone and when I plugged it in I got the screen problem that a lot of others have had where it doesn't respond much. It was like this for a while after too. The charger was some cheap **** 800mA that came with it but I doubt it was just down to mA.
> Both my kid's iPod 3G charge from their Htc chargers just fine so I'm not sure why

The Problem is with the generation and Software of the Ipod, older ones charge from
normal wall chargers i.e. HTC just fine, but newer ones are more picky. Notices this
myself with my Ipod Nanos...
you should be able to use anything up to 1.5A just fine with a usb port. Just watch for excessive over heating when the phone is on and charging. When its off and the usual over charge protection in many chargers these days they will stop once the charging has finished. I have a bunch of RC lipo batteries and have never had a problem with anything up to 2A+ for ANY battery i have charged no matter the battery makeup.. over this and you can get quick and significant problems...

that doesn't mean the device is not capable... you have 2 ends, the charger/usb port and the phone side.. the charger gives 1A, normal USB gives 0.5A, and only HTC knows what the phone side can take.. but at least 1A

HI everyone, hope thats the right forum
I have in my possession an iphone 4 charger, and since i dont have a dedicated G2X charger i was wondering if it is possible to charge the LG phone with Iphone charger?
thanks!
Well I thought iPhones use same charger as ipods which has a lot wider plug than an android charger. But if that's changed and it fits than plug it in and find out.
Sent from my LG-P999 using xda premium
I don't see it working unless you have some sort of an adapter. The G2x uses a micro USB port, and the iPhone uses a proprietary port.
please see bellow what charger i have. just need to plud the USB cord in the charger, since it have USB input.
so, technically it should work, but will this affect the battery in the long run? i mean, maybe the voltage\current values are different.
If it is a USB adapter then it should conform to USB standards and would then work. I think most of the previous responses assumed you meant a charger with the iPhone tip.

The idea itself will not work, you can pick one up from Amazon or eBay for pretty cheap.

Actually it's likely it won't work. Compare the amps on the G2x charger vs. the iPhone one (and just about any other generic USB charger). All the one's I have are different, lower, and don't work with the G2x. One of them, for some odd reason, makes the touchscreen not work at all when plugged in.

That is not correct, iphone charger will work technically, however it will reduce your battery life over time due to iphone charger are 1amp while g2x charger is 0.7Amp. Amps must meet to properly charge at the pace selected by manufacturer and battery specs. Lower amp takes time to charge, higher amp will charge fast but will reduce life.

DON'T DO IT!!!! your phone will suddenly become just like everyone else's and you won't be able to do anything about it! your technology will become dumbed down, and you will becomea victim of conformity!
HEED MY WARNING!!!
Don't worry, using that iPhone charger/adapter won't turn your Android phone into an iPhone.
The iPhone charger/adapter is a 5 volt USB adapter, it will work. The battery will charge normally, there's a charge regulation circuit in the phone and protection circuitry in the battery which will ensure that the battery won't be screwed. I use a variety of USB power adapters which range in their current rating which is the maximum current the device is capable of supplying at the rated voltage (although the cheap adapters' output voltage decreases as the current output (load current) increases. The LG power adapter I have is rated at 4.8 Volts and 1 Ampere output. I use that, a USB port on my computer which is rated at 5 Volts and 1/2 Ampere (500 ma), and other 5V power adapters. I also use a variety of micro USB cables some of which are just for supplying power, not data, and they work too.

Yes, it's totally safe. I've got a service manual for an LG phone which is substantially the same as the G2X and Optimus 2X which shows the battery charge circuitry. That circuitry regulates battery charging. Here's some more info regarding the battery:
90% = 4.05V +/- 0.05V
60% = 3.83V ditto
30% = 3.72V ditto
10% = 3.64V ditto
OFF = 3.42V
The battery voltage decreases according to the load current (milliamps) over a period of time. The higher the load current during a specific period of time, the quicker the battery voltage decreases; that's why it is important to have everything except the cell radio and the operating system off when the phone is in standby. There will be some background processes, etc., which are necessary too. Bluetooth, GPS, and WiFi quickly drain the battery. Automatic updating should be turned off always. If you're not expecting any calls, turn the phone off. Setup your phone to reroute received phone calls to your home or work phone, if the call is important they will leave a message, then pick up the messages at your convenience. Use a ROM and kernel which are known to have good battery life.
ive been useing the iphone dock to charge my g2x and it works fine lol no issue
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.
[EDIT]
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)

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...

Just saw your edit ^^
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.

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

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.
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.
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.
I have a ton of Samsung fast chargers and Samsung USB a to c cables . Would those be safe?

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.
