[Q]Charging issues after Lollipop OTA upgrade - LG G Pro 2

I've just upgraded my unrooted LG G Pro 2(D838) to lollipop. Charging through my car usb adapter is now very slow since I updated. I have tried two chargers, both of which were charging at the full rate before, one of which is a genuine samsung charger – they both have over 2A output. The phone does recognise the charger as an AC charging source, but currently isn't charging above about 200mA.
I am using a Samsung AC charger at home which works as normal. I've had a bit of a look online and people are experiencing the same issue with the LG and other lollipop devices. One of the suggestions was to short the data pins on the usb cable, which I have done but this doesn't seem to have fixed the issue. If the phone is off it charges at the faster rate.
What I can't work out is why the charging speed is different between the samsung AC adapter and the car charger, when it detects both as an AC source? Is there some communication between the two, or are there any car chargers that will provide high speed charging that will work?
any suggestions are appreciated!

[Solved] USB only charging with third-party chargers

[Solution if you are facing USB-only charging with third-party AC chargers on your Nexus 5]
Hi Guys,
Initially, my Nexus 5 ONLY charged at USB mode with any other charger than the one supplied. I tried 5 chargers including the Trent 2.1A car charger and BB PlayBook high-speed charger. I also tries using the supplied USB cable with another charger but it was a slow-go.
Then, I noticed my buddy's N5 did not exhibit this problem.
My only solution was to reset the phone, log back in and charge with the supplied charger to 100%. Then, it magically started to show AC charging with other charges.
I wanted to share this with others in case they faced the same situation and were considering RMA due to hardware.
Kit Kat still have way too many bugs. (Settings is constantly crashing in the battery menu when I plug the charge in and out on two of our N5s.)

Thanks, I'll try reseting my Nexus 5 when I get home. Although, I havent been able to charge it using any charger not sure if the battery life is reporting correctly too. When you first saw the issue with yours not charging using the cable and ac adapter that came with your Nexus 5 did you happen to notice if your device was still asking you to connect the charger or not? Mine is still telling me I need to connect the charger or cable, even though I have my USB plugged into the device. I can send commands to the phone fine using adb or fastboot, just wont charge.
Unfortunately your trick didn't work for me with my N5. My N5 charges off of SOME chargers (The N4, N5, N7 2012, and Samsung 2.1 Chargers, as well as my EasyACC 1200 battery pack, only port 1.3 volt, all others show as USB.) My car charger fails, Duracell 2 USB port with 2A output, and so does every other battery pack that I own fail with charging. All report USB Mode. I think it has to do with the Quickcharge 2.0 or possibly the fact that this has G2 innards to an extent. The G2 has quite a few chargers reporting as "Slow Charge" rather than "Fast Charge." Quite Irksome but I suspect it will be resolved with an update soon.
To confirm that it wasn't a hardware problem of my N5, I borrowed a Coworker's N5 and experienced the same thing on my chargers.

I returned my first nexus 5 to google because it did not charge unless it was with the original charger. I tried it with the USB charging port on my radio and also a sony USB cable + plug combo and the charge was terribly slow. I have a nexus 4 and 7 and they had no issues charging this way so thought it was a fault with the handset.
When I received my replacement I was really hoping this issue was resolved but sadly not. The second handset had the same issue. I then researched online and came across this forum post. I reset the handset, charged it to 100% with the cable and plug provided with the phone. Just to be on the safe side I discharged the handset fully and charged it to 100% again. The same fault reoccured. I then compared my nexus 5 to my 4 and 7. When charging the 4 and 7 through my radio, it showed charging via AC on the battery properties on the handset. The 5 in the same situation showed charging via USB. I then tried to charge my 5 using an emergency charger I had lying about and to my surprise, that charged fine showing as AC charging. I then took the USB cable from the emergency charger and plugged it into my radio's charged port. It showed AC again and charged as normal. I then used the original USB cable I always plug into the radio into the outlet of emergency charger too and that showed AC on the phone too.
I don't really have a conclusion to why this it charges fine with one power source and cable and not another as there seems to be no logic to this. I think the nexus 5 is really picky how it likes to be charged. I can't see why this phone is soo finiky charging when all my other devices charge fine regardless where and how. I am now worried that if I'm at work or out and about and need an emergency top up my handset won't charge. I really hope this is a software fix

[Q] Nexus 5 alternative chargers?

Hello,
I was wondering, can I use the old charging cables from an LG Optimus Black and Samsung Galaxy S2 to charge the Nexus 5?
I also have a car USB adapter and a spare USB-to-microUSB cable.
Can I use all sort of plugs/cables that match the connector size, or should I pay attention to any details regarding current/voltage?
I noticed the original PS for the Nexus 5 supplies more power than all others I have, but that may just mean that it would charge slower, which to me is not an issue.
I not only want to avoid doing any damage, but also of course shorten the battery life!!
Thanks

Any Micro USB cable will work with the phone and you shouldn't have a problem with voltage or anything like that dont worry bro
I notice nexus 5 is very picky on your USB cable if u want a fast charge. So of notice it going pretty slow. Try another cable
Sent from my Nexus 5 using xda app-developers app
Any USB charger should be 5V. You could in theory get a cheap charger that is off by some amount, but even then it would have to be significantly higher (5.5V+) to cause damage.
Current just affects the charging speed. A 0.5A charger is just going to charge your phone slowly. Your phone won't draw more than 1.2A though, so a 2A charger would be fine.
I was wondering about the USB cable as well, if I recall correctly, didn't the Nexus 4 had one less pin in the micro usb cable and Google only recommended using their USB cables?
I have a tone of Samsung micro USB cables from my numerous E4GT that I went through. I also noticed that the N5 charger brick says 1.2 on it so it's not your standard 1 amp charging brick.

Unfortunately the N5 seems to report most chargers as USB Mode chargers rather than AC Mode. I've noticed this with my Battery Packs, multiple car chargers, as well as multiple home chargers that are cheap. The N4 reports them all as AC chargers, but the N5 reports them as USB Chargers

Silly question, but how do you tell the difference on your N5 from USB charge vs AC charge?
Not a silly question at all. Go into settings and check "Battery" when you get in there, It shows you xx% Charging ("Whatever you are charging through")

Goto Settings -> About -> Status -> Battery Status: Charging (USB) / AC
I've not used the bundled charger, just re-using my old one that is an AC Adapter with a USB cable. I'll check tonight to see if it's charging in USB or AC after all.

[Q] List of Nexus 5 car chargers that charging in AC mode

Hi,
I would like to create list of car chargers that are able to charge N5 in AC mode.
Till now I have found only one review on Amazon on: "PowerGen Dual USB 3.1A Car charger".
Sorry, but I still can't post links.
I want to buy something that works for sure.
So, please share your real life experience...

I got this one http://www.amazon.co.uk/Anker-Dual-...5839252&sr=8-1&keywords=anker+usb+car+charger is working fine, it has 2 ports one of which says it is for apple but works just fine on any device both ports charge over 2 Amps.

Thanks for replay,
Can you please Goto Settings -> About -> Status -> Battery Status: and verify that you see Charging (AC) ?
I am also able to charge with old Griffin charger, but it only works with "Charging (USB)" - 0.5A.
Thanks...

Hi, yes it does say charging by (AC)
Ady1976
Thanks a lot !
Now I have one more charger to choose from -
0.5A is USB level so that's why that one doesn't work, anything that charges at 1A or over should be fine.

My charger is capable of driving more than 0.5A, but the phone don't "understand' it.
Android determines that a charger is a wall charger (as opposed to a computer) by the fact that the data ports are shorted together. Apple chargers don't do this, so most chargers made for Apple products will only charge Android devices at 0.5A. Heck, almost no car chargers do, unless they were made specifically for an Android device. Here's what I did:
I ordered this Griffin car charger, mainly because of the size. It just BARELY sticks out of the car's charging plug. Then, I ordered the Nexus Wireless Charger, and used the cable it came with (minus the wall plug). Presto... Qi wireless charging in my car. The magnets hold the N5 in place nicely so it doesn't slide off the charger in my center console, and the charger I linked easily supplies the 1.8A that the Nexus Charger expects.
The catch is that this charger was designed for an Apple product, so I had to carefully pry it apart and short the center two USB pins with solder using a soldering iron (those are the data pins).
EDIT: I should point out here that the Nexus charger may work fine without shorting the pins. I didn't test it. I wanted the ability to quick charge via cable if necessary, since Qi charging is a bit slower, so I shorted the pins, but if all you're interested in is Qi charging, you may be able to get by without modifying the charger. If someone wants to test this, please let us know.

Thanks for the info. I have some kind of Griffin charger with 2 USB ports.
So, I will try to do the same - shorten data pins inside the charger.
I will post it works
Just an FYI, I was charging with a charger that listed AC mode last weekend yet it wasn't charging faster than the power was draining.
Not all the AC modes officially charge at a faster pace unfortunately. My Galaxy Nexus car dock charger though did charge it at a proper AC pace.
What took me a little while to figure out is that this issue may not be as related to the charger as it is to the cable. I tried 3 different car chargers and none of them would keep up with GPS battery drain in the car. I figured out that common to all 3 chargers that I was trying was the cable. So I bought this cable and now all 3 of the same chargers work great. I am finding that even at 1.0A you can keep up with the gps battery drain. At 1.5 amps or greater you can charge the battery in the car while using GPS full time.

This is because some "charge only" cables don't have data pins at all (usually, because they came with a charging dock of some sort, or were designed for devices other than Android). Remember, I said earlier that Android notices that it's on a charger when the data pins are shorted. If they're missing completely, then it will only charge at 0.5A.
My rule of thumb is to stay far - far away from charge-only cables.
I bought a "2.1A Car Charger" with a single USB port (made by PNY....Amazon for about $6 shipped)... opened it up and soldered a bridge between the middle 2 USB pins.
Previously it reported Charging (USB), now I get Charging (AC). Confirmed with a widget that showed charging amps, the number went way way up.
Presumably any of these chargers claiming high-amp output will only work with iDevices, I guess they ignore the USB standard that if the two middle pins are bridged, its a power-only connection and full power can flow.
I did test this on an HTC One X running 4.2 and it reports Charging USB though, so there is a dependency on one of the newer Android kernels (my N5 runs 4.4.2)
Edit: oh yea... with my newly modded charger, I tested turning on Bluetooth streaming audio to my car, GPS on, navigation running, screen on, 100% bright, and wifi tethering enabled, and i STILL had a net charge going.
I've just bought a Blackberry Premium In-Vehicle Charger and my N5 recognizes it as an AC charger. The phone pulls around 1A from it (it's good for up to 1.8A). This is it, though I purchased mine from a local store.

S5 car charger that actually charges?

Hi all,
I have a couple of micro usb car chargers and when I was using a Navigator app whilst driving somewhere my battery just died despite the charger being plugged in and showing as charging?
I bought another charger off ebay which is a usb car socket with a genuine Samsung micro usb cable. It shows as 1A output and I plugged my phone in to charge at 1% with google maps running, half an hour later it had only gone up to 2%?
What I did previously was plug the 3 pin mains charger into a 240V inverter plugged into the cigaretter lighter socket and that actually charged the phone. Any ideas why the car chargers won't charge it, does anyone know of a car charger that actually will charge the S5?

If your battery goes above the 42°C the Kernell stops charging; the consumption of the phone can be up to 700mAh, so with 1A the charge must increase in about 5% in half an hour. with a 2A charger the kernell will accept another 800mAh as much, so you can fully charge your phone in more than three hours, (whe in a fully use) but always with abattery temperature lower than 42°C
I personally use the Anker Qualcomm 2.0 car charger, no problems, I like how fast it charges even if I am heavily using it (unlike other chargers I have owned)
Excellent,thanks both. I got hold of a 2.1a charger which seems to be doing the job well at the moment. Interesting thing about the battery as I have felt it get very warm at times, not always when charging though.
I bought this [Quick Charge 2.0 Car Charger]CHOE 30W (with Most Powerful QC 2.0 Port) Dual USB Car Charger with 22AWG 3.9FT Micro USB Cable(White)
Use coupon code 88PKZDLL on checkout to save $5.45 making it only $10

I can really recommend this one: Aukey® Kfz Ladegerät 4.8A Dual Port Autoladegerät mini Car Charger, 2.4A+2.4A(4.8A max)dual Ausgänge für iPhone, iPad, Tablets, Smartphone, Navi u.a. USB-Geräte (4.8A dual Port mini Schwarz)
(Can't post the URL because of anti-spam bull****. Just search for that strink on amazon.de)
It's powerfull enough to charge a S5 and a S5 mini for example.
I have a genuine at&t 2.1 AMP car charger for my SGS5 and I never had any problems with it. It also has an extra USB port so you can charge two devices at a time (the 2 amps split to 1 amp for each device).

Anyone have luck with wireless charging receivers?

I recently got a wireless receiver and charger off Amazon, but haven't had any luck so far. The phone days it's charging, but overnight the percentage never changed. Assuming it is just such a slow charge.
Anyone have a better experience?
HTC U11 does not support wireless charging. Did you do something to add wireless charging to it?
EDIT: Sorry, missed the part about you using a wireless receiver. It should work. Maybe try on a different charger to isolate if the issue is with the receiver or the charger.
Very slow charging
I bought a wireless charger adapter that plugged into my usb-c port and used it for about 3 months. It charged very slow and I soon gave up on it. It did not charge as slowly as what you reported though.
