I tried plugging in my mini usb cables I have used for other phones but it does not fit. It looks like the opening on the MT is larger then the standard. Is anyone else noticing this?
I've used all my other ones fine. I use a blackberry mini usb to charge while I sleep, another blackberry cable to hook to my laptop at work, and the one that came with it at my home desktop. No problems for me.
All my chargers work fine as well.
It uses microusb, not mini. The standard ones work fine.

It's not the volts, it's the amps....
Just as an FYI, one thing to watch out for even though the USB plug is standard is that the power output can be different on different chargers. 5v is the USB standard, but the amperage can vary. I think the Max is 1A for the USB (2?) spec, but I'm not sure if or what the Min amperage is. The V/A output should be listed on the charger.
The plug that comes with the mt4gs is 5V-1A. When I've tried charging phones (e.g. Blackberry) in the past with a 5V-.2A charger, it has worked extremely poorly (half charge after 12+hours). I would expect similar results with the mt4gs.
websculling is right. Additionally, using the wrong amperage to charge significantly decreases the number of charges you get out of your battery before it fails. Stick to chargers that have the amperage the battery was optimally designed to accommodate.

So amperage is what matters with USB charger compatibility and not the voltage?
My wife's old feature phone came with a micro-usb charger so I'm trying to figure out if it will damage by MT4GS or the MY3GS I handed down to my wife.

Both are important.
Too high of a voltage and you'll burn up the battery or damage the charging circuit.
Too low of an amperage (blackberry chargers) and you'll wear out the battery much more quickly. Trickling in power like that to these kind of batteries that weren't designed to handle it that way 'ages' the cells and reduces their already less then impressive lifespan.
Battery tech is better then it was even a few short years ago, but these kind of batteries in this small of a package are barely efficient enough to be useful. A few more years and things will be a lot better, but for the time being you should really try to care for your battery as best as you can and not abuse it.
I'll post the link here to the XDA battery writeup I linked to in both the anker and mugen threads later on when I get back to a real computer and am not using a phone app to browse the forums.

That's not too far out of spec, but I would rather let my battery die then use it, personally. Finding an AC adapter that is in spec is very easy and very cheap.
Something to note here is the doubleshot does not have a hardware regulated charging circuit inside the phone - this is the reason why it was rough with the early unofficial ClockworkMod recoveries and the source of their charging issues.
Knowing there is no hardware failsafe, it makes it that much easier to do permanent damage to the battery, device or both.
Do what you think is best, but just want you to have as much information as possible to base your decision on.

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

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...

My n5 charging real fast fatter t than my n4!

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)

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.

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 have a Samsung wireless fast charging pad I bought for my S7. Is there any difference in the charging speed between it and the latest dock style ones?
Nope

Maybe you know. I was told that using non-original wireless charging is bad because they spoil the battery. Is it so?
Generic wireless chargers do not fast charge in my experience. I have tried 3 off of Amazon so far.
I have a Seneo Fast Charger stand and its been great .
As long as the wireless dock is Fast Charge capable and your adapter is QuickCharge 2.0 compliant it should work. I have four Seneo Fast Charge docks that I use with both Samsung and RavPower QC 2.0 adapters and they work great with my S7 Edge. I will test when I get it but I'd assume the S8+ will work the same.
You know if it is working because the phone displays two messages when you dock it.
"Charging wirelessly xx%"
and then after a second or two
"Fast charging wirelessly xx%"

I believe the S8 (like the S7) can accept up to 15w wireless charging (Qi 2.0 spec) but most chargers barely output 10w. Not sure why but I would be looking for a good 15w output charger unless theres a reason not to.

What does "spoil the battery" even mean?

I think the reference is to batteries losing capacity. The older a battery is the less capacity it holds. A battery rated at 3600mAH might only hold 2000mAH after a couple of years of use. High charging current causes a lot of heat buildup in the battery and will shorten (spoil) it's life.
Best way to tell if your battery has lost capacity is to measure charge time. Having it die quickly could mean it's just running too many apps, but charging time (with the phone off) should give an indication of battery capacity. If your battery charges twice as fast as a new one, it's lost half its capacity.

Got it. Sorry, I actually thought they meant that the battery spoils. Like the way some "normal" batteries blow up if left in devices for too long. I was seeing memories of the S7 nightmare.
AFAIK, the only listed change between the Dock style Samsung Fast charger and the Convertible Fast charger is that the new 1 can be changed from dock to pad.
I just picked up 2x Dock styles from amazon for 40 bucks a piece, way better than spending 70 for the convertible style.
Or these?

I was amazed how quickly they showed up too. Took 3 days from order to delivery. I think they purposely put almost 2 weeks delivery time just so that when you get it "early" you're amazed.

Means that the battery holds its charge less. Faster discharges, in general the life of the battery decreases
If you use Qi wireless charger, it has 1.4x faster than traditional wireless charger. Built-in 2 coils offer a wide charging area, which allows you to place your device in either portrait or landscape position. You can also continue using it to read, watch or type while the battery is being replenished.
In this video I test out both dash charging on the Oneplus 6, and adaptive faster charging on the Samsung Galaxy Note 8 to see which one is faster.
Both devices have a 3300mah battery.
mod edit - link removed
And i can say without watching and without click-baiting that dash charger is much faster! You can calculate it for yourself too. Samsung adaptive fast charging is based old Qualcomm Quick Charge 2.0 and output power is ~15W. Dash charger is 20W.
But nice video still!
Does it really matter?

Yea everyone will just try to find a way or to prove that the phone they bought is best so they do useless comparison all going to change phone within a year it doeent matter stop speaking for thr company just use the phone no offence for the post
I've not watched the video but something else to consider.
Dash charge does hot heat up the phone whilst charging. As such, it's not only quicker but it also does it in a way that is better for battery longevity.
You can use this charging solution whilst driving in the car with GPS and Bluetooth for example without hearing issues which you really can't do on Samsung adaptive charge or other battery charging technologies.

My phone gets warm/hot aka nothing alarming. But the same way op6 charges with dash is no different than the note 8 I used for 6+ months.
It's quicker but not night and day. It's not 2013 anymore. Fast charger with my mate 8/9 was just as fast and battery lasted just as long with all the bells and whistles.
But I personally don't live in a 3rd world country where chargers/outlets arent available.
I thought it was the company I avoided but the community (mostly op forums) are reaching for anything. Battery life and maybe dev community are the only positives.
Never personally had a issue with any other battery technologies.
