Car Charger and Wall Charger

As far as i can tell i have not had an shutdowns or lockups etc.. while using the LG charger that came with the G2x. I had been using the one that came with my Nexus One and it seems that almost every time i have used it, i would get a shut down or a reboot or black screen of death etc... usually at a full charge. ie i would wake up in the morning to a unresponsive phone.
Has anyone bought an extra wall charger or a Car charger that did not cause any issues? If so where? Did anyone buy the ones ("They call it a Universal charger" ) directly from TMobile? Since technically in the manual LG says to use their own charger..but i thought all manufacturers say that.
I am wondering if the one that came with the Nexus One has the built in circuitry for not letting it get to much voltage or whatever they are supposed to block. I have seen some online that say they have something built into the charger...which not having it may be the issue.
I thought the phone does ..switches to trickle charge when almost full. At least my Nexus did... but i get lock ups sometimes no where near full... with the G2x. And i get it every so often with my Car charger too.
Thanks

I've been using the ones from my HD2 no problem yet.. :knocks on wood:

Before you go out and buy a generic charger from Ebay, make sure you check out the miliamps on the chargers. The G2X AC charger is 1000 mA which is pretty high. My previous Samsung phone was 700mA which was less. If you buy anything that has a low mA rating it will take longer to charge. I bought a cheap generic charger from Ebay before and it was rated at 300mA!!! That's barely enough to keep the battery level the same while you use your phone or have it on. Don't use your USB plug from your computer because the mA is very low and you will run down your battery having your phone on. A good 2nd home charger is the Blackberry AC charger. They are under $5 from Amazon and they are 700mA.

For the car buy this Motorolla charger. 950mA! and about $6

Thanks for the input everyone. I will look into grenademastas suggestions.
Just an FYI... still
...as far as I know, i have not had a "self reboot" (well no lockups for sure... self reboot you have to look for i guess...) since i began using the charger that came with the G2x as my primary charger, for overnight charging.
I also started rebooting my phone once a day when i take it off the LG charger.
And also since i did this, I have not woke up to a "unresponsive" phone where i had to do a battery pull. I was using my Nexus Ones charger as the primary charger.
And i had switched from Launcher Pro to Zeam. So i will try going back to Launcher pro for a few days and see what happens. As i thought original it was Launcher pro causing reboots and lockups. Zeam is pretty fas so if no lock ups , i am not sure what i will stick with.

Thanks for the link, I ordered one for each car. Ive seen a few Micro USB chargers locally for $10-$15 but they never list the ma on the package.
My current charger can only keep up with the N1 when not running GPS. it barely keeps the G2X steady

Trust story. I found a micro usb charger in my closet and started using it the same day I got my phone because the cored was longer. It was taking FOREVER to charge and when it was at 100% if i started using it while plugged in it would still drain to like 97%. I was like wtf everyone said this phone charges faster than others. Then I checked the specs of the charger and realized it was the charger for one of my old bluetooth headsets and the output was only 150mah .

Charger getting hot | Controller for quake

Hi guys, I got 2 subject so I thought I'll just make one thread for this.
I'm from EU so I used my US charger with an other plug. Seemed to
work great, doesn't complain like it does with my HTC phone charger.
But now the charger gets pretty hot, along with the USBplug that is in the charger. Should I be worried? I would say its about 50-70celsius.
_______________________
So I got Quake from preware, but it doesn't work with touch only (even tho there r touch controls?) so Im wondering if its possible to get it working with this:
http://icontrolpad.com/
That would be nice with the snes emulator also so I might buy it, its very expensive tho but I like the oldschool'ness of it.

You're likely to burn it out if you keep using it, don't leave it on unattended.

Sure? Does your get hot?
The charger should handle ~220v as we got here. So I don't get why this shouldn't work.

Isnt there a way to find a compatible European charger without paying 30$ for the travel pack?

Pretty much any micro-USB charge will charge the Touchpad, it is just some will be quicker than others. I am charging from the USB port on my laptop at the moment and it has upped the charge by 8% in the last hour or so with the screen off.

Yeah but the normal one gives about 30% on that time. But as I said, it should work, no problem. I don't think its uncommon for it to get hot but I'm not sure tho

My official charger gets quite warm, together with the USB plug. Clearly that is the only device that will charge at full speed and without a warning on the screen. However, as I was trying to point out, you don't have to go down the official charger route if you are prepared to either accept the on-screen warning or a slower charge rate. The Blackberry Playbook charger gives 5V 2A and although it comes up with the on-screen warning charges almost as quickly as the official unit.

I bought one of these http://www.mymemory.co.uk/iPod---iP...s-USB-Charger-and-Socket-for-iPod_iPhone_iPad the other day, rated at 2.1 amps (though the unit shows 3 amps). I get the dire message about not enough voltage or current but it works fine and quickly. Obviously I don't use the supplied Apple cable...

On Charge Draining Like No Tomorow

I Have A Samsung Galaxy Note 10.1 I Got It About 8 Months Ago I've Used The Samsung Official Charging "Cable" For Most Of That 8 Months but about 2 months ago the cable became loose at the Samsung cable to tablet end exposing the wires so I was careful with it and put it away and used my friends official cable then he needed it back so I went off and brought a generic cheep cable for $3.50 So all was good there but slowly I've noticed my battery going crazy like taking longer to charge "2 Days to full" and things like it discharging by 2% when I am on Google while its on charge and when its off charge playing 1 game uses almost all the battery.
so being the awesome soldier that I am I made myself a 5cm cable hoping that the long cable I was using had something to do with it but still I had the problems listed above so I did some Googleing and maybe a 2.5A charger would be helpful But its not recommended. also I sent a email to Samsung and being the "SUPER HELPFULL COMPANY THAT THEY ARE" has not responded to my emails in the past week's Also I Spoke To A live chat person thing and Being "Soo Helpful! " Said that its a hardware fault and I need to take it into a Samsung repair place and fork out $100+ Bucks to get it fixed "HELL NO AnT No BoDy GoT TiMe FoR ThAt" so I didn't go to Samsung to get it repaired so I want to know if any of you guys out there have any idea to fix this problem im having because its so hard to do anything.
Just Checking my emails while its on charge uses %4, On Google for like 5 mins Uses 2%, Playing A Game For 30Mins Uses Well Almost Flattens It, And Watching Some YouTube Takes It Down To 0% And Then Shuts Down( I Watch Lost Of Videos) All This While Its On Charge
At The Moment How Im Copeing Is I Carry Arrount An Inverter And A 12V Battery To Keep It Charging

The SGN 10.1 charging cable is a specially designed cable to deliver 2.1A 5V to the device.
Most "cheap" cable on the market can only deliver 0.5A - 1A 5V when used to charge SGN 10.1
You should find the correct cable specifically built for SGN 10.1

Thanks but how can a cable make all the difference i managed to charge off my old one its just got exposed wires and it still drains when i use it

Are you certain that the battery is actually draining that fast and not simply misreporting it in the UI?
I had a similar problem where the battery didn't seem to last but I eventually noticed that a reboot would completely change the amount of charge remaining, sometimes by as much as 20%. I cleared the battery stats and is been fine since.

Well actually when-ever I turn it off it doesent charge much and if I restart it the battery stays the same but over the last few days ive noticed something weird when its on chatge and I play a game it drops about 20-30% but when its not on charge and on battery it drops by about 5-6% could the charger be draining it? also I have a new new cable its generic (IM NOT PAYING $60 FOR A CHARGER CABLE) and there is no difference still does the weird charging thing also I tried the old cable and still does the same thing the olny thing wrong with the old cable is that the wires where exposed so I dident want to use it just incase it broke

If you don't want an OEM cable and charger you can buy a crap chinese one. But as you and many others have discovered - they suck. This is one of the biggest complaints I have always heard about Samsung.
The solution, and the only on that I have found that works 100% of the time is to buy a replacement from Samsung. Period. Nothing else works like the OEM parts because they aren't OEM parts.

The wiring on the OEM cable is somehow different than most cheap cable.
I'm experimenting by buying a 3M long "cheap" N8000 cable on eBay, may be it can help (delivery time is VERY long )

What ROM are you using?
Stock or Custom?
Rooted or not?
If you are Rooted (Stock or Custom) you can use Battery Calibration app to erase batterystats.bin to calibrate your battery percentage which are needed if you change ROM.

$60 just for a cable? Really? I live in the UK and I bought a whole new charger (official Samsung one, too, including a cable) for about £12 on amazon. Just go to Amazon and replace the charger, it sounds like it'll be cheaper than just the cable (probably 15-20 USD or maybe 30-35 AUD, I'm not sure what the rate is and where you live ) and if it is a charger related issue that'll be fixed too.
Just so you know, I bought the 'travel charger' (the white one) and it works perfectly. Supplies the same current and voltage, and it's a smaller unit, and cheaper! I'd just look into getting one of those.

[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.

using my lg g2 charger and it charges my nexus 5 super fast. 1 hour charge will give me almost full battery

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

Oh that's bad , I didn't know that!
Would just be the "reference test" since the stock charger should meet all the specs (and works fine here with every cable).

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).

Oh that's bad , I didn't know that!
Would just be the "reference test" since the stock charger should meet all the specs (and works fine here with every cable).

Absolutely. A control of sorts. Might as well.
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.

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.

Stock charger - charges slow and drops battery

Hello there,
I decided to open this thread as I've now had a bunch of issues with the stock charger that came with the device and it would be interesting to know if there's anyone else who's having this type of issues.
The exact issues that I've been having with the stock charger seems to be that the charger doesn't output enough of a amperage for the tablet to hold charge while in use, and even when it's not in use it takes almost 7-8 hours to charge from 50% up to 100%. It's as slow as if I would charge it from a regular USB port, if not, even slower and I don't really know why exactly this happens as it says that it's charging from AC adapter in settings.
To comfirm my issue was not related to the tablet itself, I used another charger that's rated at similar specs to the stock charger (2.1A) but with the same Micro-Usb cable that came with the tab. With that charger, it charged up from 50% extremely fast (around 1,5 hour) and I could even use the tablet while charging without any battery drops. So that comfirms two things, it's not related to the tablet or data cable but to the actual charger itself.
Anyone else that's been having this type of issues with the stock charger?

My tab needs max. about 3 hours to charge full and imo it's ok. Tried charging during Half Life2 gaming and can confirm that there's not a lot of charging going on, maybe 1or 2% in an hour. But that's ok for me, as long as it doesn't start to get emty while charging during gaming.

The charger is defective or don't bring enough power to the unit. I also get negative charge while playing high end games an also increase when i am, on Optimized mode. Many others has reported this situation on GeForce forums but nVidia is quiet about it.

I get negative charge even when doing basic tasks like listen to music or watch a video with the stock charger, so I guess my charger is faulty. I've already reported the issue to Amazon and they gave me a 50GBP partial refund (80 USD!) because of the faulty charger without having to ship anything back.
I just find it odd that theres many people that have the issue and nvidia doesn't seem to do anything about it either!

If i were you, i'll check with another charger doing normal stuff, if you still get negative charger maybe it could be your battery itself.

My guess is that a faulty cable or the charger itself is causing D+ and D- to not be shorted together by the charger, resulting in the tablet thinking it's charging from a USB port instead of a dedicated charger.
Does device status report charging state as Charging (USB) instead of Charging (AC)?
I admit I never even unwrapped the stock charger, I've got one of those nice Anker 40W 5-port chargers along with a bunch of 24/28AWG MicroUSB cables from Monoprice.

The charger appears as AC in settings, so it should be charging faster than it does.
I'm using a charger similar to what you use right now, a Dodocool 4 port charger that works great! However, I'm using the stock cable.

First make sure you are using stock charger and cable.
If you see discharge during non intensive activities you may have a defective charger. Nvidia has rma'd the charger by itself for people.

I have the same issue but my charging time is a bit better 3-4 hours. But what is really annoying that it makes a lot of electrical noise. I have a lot of things that I charge, but I have never heard this so load earlier. Its coming from the adapter, I can cleary hear from 3m. Anybody has similar issue? I try to record the sound, and send to nvidia. Maybe they will react.

I can confirm that this combo works a treat for my NST. I use it to simultaneously charge my G3, NST, N7 and some small LiPos. Fast charge.

Sorry to dig up this thread but I've had the same issue and i was WTF-ing like crazy until i switch the USB cable to a charging cable i got from a power bank... The charge time dropped from 6-7 hours to 2-3 hours. I'm not sure why, perhaps my cable is faulty or perhaps it was meant to charge like this, or perhaps it is supposed to be used to connect a controller only (both ends seem to have a controller icon on them)?

It's not due to the MicroUSB cable but due to a wallwart that's messing up the amperage I believe, as I've used the MicroUSB cable with other wallwarts and it charges normally then

You are correct. I charged the tablet at home 2 times this weekend and it's definitely an issue with the charger as it sometimes charges properly and sometimes it does not.

Get in touch with the retailer you got it from and ask for them to provide you with a proper charger, as a compensation

A bit hard to do since i got it from amazon.com when i was in the US (back in EU now) and there's no point in returning the tablet just for a semi faulty charger.

Contact amazon and tell them exactly about the issue, they'll compensate you for it probably. I got 50£ back from Amazon.co.uk for the broken charger, which is quite a bit of money.

Thanks for the tip, i'll give that a try

Well, same thing here. Just noticed it while using Skype. Battery dropped from 100% to 95% pretty quickly while charging.
I'm going to ask Amazon for another charger or compensation.

I have a 2.4A charger and still battery no good.
I lose around 2% per min of battery charge while idling with battery saving features on (2 cores shut off, CPU frequency set at 50% and Framerate locked at 30FPS) when ingame the battery drops 2-3 times faster. takes 2 hours to charge from 97% to 100% and 2 mins to lose that charge. I think I bought a Tablet that has a faulty battery as this is not acceptable. My tablet is unusable as the battery takes a couple of mins to lose 3% of charge and a couple of hours to regain the 3% charge only to lose that charge (and then some) when I try to use the tablet.
