i am thinking about if my E975 is limited when it comes to how many amps it can charge with bcs i recently brought a 2A charger also tried it out on my Google Nexus 7 2013 and i don't feel like it charges that much faster then my original LG charger with a 3meter flat OEM kable.
the charger i brought is said to charge with 2A while the original LG is only 1.2A shouldn't i be feeling a difference?

No, you shouldn't. You can plug it into a 10 Amp charger, but the phone will only draw the amount it needs. Remember, it's not the charger pushing the current to the phone, it's the phone pulling it from the charger. The charging current is determined by the phone - each Li-Ion or Li-Po battery has a controller curcuit. The important thing is for a charger to be able to provide what a device wants to draw - otherwise, it would charge slowly, or not at all. So, a charger should be rated for not less than X Amp. More amp rating won't hurt, but it won't increase the actual current...
oh this is very useful. I also had the same question.
mine came with a 750mA (.75A) charger. As I left my charger at home during the holidays, I had to make due with one that I bought from a nearby tech store. I was very happy with the charger that I bought as it charges my phone really fast. I found out that my new charger was also a 2A model.
so I guess, in my experience, I noticed a big improvement in charging speeds comparing the 750mA with the new 2A charger. But I guess coming from a 1.2A charger, it only makes little difference.
hi. the battery charger that i got with my LG optimu G Pro is ****. its just now that i checked that i have been deceived
its chinese copy and its only 0.2A charger...
now i know the reason why my phone charges soooo slow...
anyways. i think Note 3 and iPad air charger are 2A and 2.4A. so can i use iPad or Note 3 charger to charge my phone? will that be ok?
any one here using that?
thanks
Use OEM LG charger with 1.2 output. I am using LG G2 OEM charger and it charges very fast! But not sure it's compatible completely

If youre tech savy you can make your own,you just need a switchmode 5v regulator (they usually put out up to 3 amps) and you put a resistor across the data pins (i think 100 ohm) and itll charge the phone as fast as it can safely charge. I made my own charger for the car and the phone gets fully charged in about an hour and a half. (With screen on and playing Bluetooth music). Other wise if you buy a charger, get as many amps as you can. Atleast 1.5+ . and to make the phone charge in AC mode if it only says USB you need a resistor across the data pins.
Thats funny... my G Pro came with a 1.8a LG charger, my G2 came with a 1.2a.
Yeah you'll be fine. The "extra" amperage in the charger is available capacity that your phone can draw from, it will regulate itself but that can also depend on the charger and how they pin the USB. Its different than if you have extra volts (like a 10vdc charger which would provide too high of a voltage and damage electronics). I usually charge all my phones at when I get home with my wife's iPad charger super fast. Likewise you can use your LG charger to charge the iPad but will be slower since it has less amp capacity to supply. Part of the reason they provide the bigger charger is to sustain battery level while using the device (It should be large enough that the battery doesn't drain while your using the device while plugged into the charger).
Most computer USB ports typically provide .5a of power and will be your slowest charging option, at best you get a newer laptop with "high capacity" ports and it provides only 1.0a.
I've been using an iPad 1st gen charger with GPro since day one, been working flawlessly for 4 months now. Charges fast.
Dear Friends,
I need your advise regarding charger.. I am using 5v---2A charger for charging my LG G Pro.. I takes not more than 1.5 he's to fully charge... is it damaging my battery... and what are the stock charger specifications?
Looking forward for your prompt response

I thought stock LG G Pro wall charger is 1.8A? Either way, all the latest phones with high capacity batteries use 2A charger for faster charging. Also, typically it should not draw more current than it's rated charging speed. The rule of thumb is to use a charger with a same rating as a stock one.

thank you very much for reponsw ... please also confirm 5v---2A charger is safe to use?

It's safe, but I don't know where you got your charger For example at home, I use only brand name 2A chargers from Samsung, Anker, and UE/Logitech for charging of all of my accessories from 500mA to 2A (they only draw as much as they need too even so all my charging sources can provide up to 2A of current). But if you guys $4 no-brand charger from eBay, doesn't matter what the label say - you can never guarantee safe operation at max current since those are cheap without a good over-current protection or component rating without a margin. I would also recommend asking other LG G Pro users in direct forum sub-section of XDA: http://forum.xda-developers.com/optimus-g-pro
Good luck!
Does anyone know the minimum specs for buying a charger? 2.1A or higher? Looks like some places are adding watts to the output capability as well.
All my old chargers aren't cutting it anymore and I need something for the car and other outlets. BTW, I have a VS985.
Thanks in advance!
The stock is 1.8A. So I'd go off that.

2.1 A won't hurt your phone but keep in mind charging is limited by the cable and the chips capacity. Let's say you have a 5A charger your phone won't charge at 5A but rather its max rate. Make sure you get a good cable to use as well because if it can't handle the amperage it could cause serious issues and or fires in some cases. I use a 2.1A charger and its fine.
Hey all, just got my M9 on Thursday and I've been finding that charge speeds appear to be very slow. I've used the Anker 40w 5 port charger which should auto detect charging speeds and I'm getting 270 mah read on ampere. Is this just an ampere issue, or am I seriously charging that slowly?
I say this in comparison to my GS4, which when using the same charger goes at as fast as 1900 mah (using fast charge. Right now I have it down to 1200). So I know the capability is there, it just seems like the M9 isn't taking advantage of it for some reason). Anyone else having issues with it?
I'm pretty sure ampere is wrong. It tells me the same speed whether I'm using USB on my computer, my oem charger, or my Quick Charger. And they all have very different charge rates.

Ampere has a hard time with quick charge units. Using a slower charger actually gets you more accurate results. I bought the anker this week as well and it'll sometimes read 290 which I know is wrong.
Okay good to know that it's not just me....anyone know of another app that can give me more accurate readings?
Either way hope Ampere improves
Works fine for me

I am the developer of Ampere. I just found this discussion by accident.
I would just have to tell that without your help Ampere will not improve. It is not possible that I buy all devices for the development. Please join the Ampere Beta tester group on G+ and please read the Ampere development thread here on XDA. Maybe we can find a way together to get Ampere working with HTC M9 like the Nexus 6 which already works with Ampere and Ampere can detect the turbo charger.

I actually just joined after you replied to my review on Google play! Gonna get home tonight and follow the instructions to try and get it working. Thanks for the response, really appreciate the work you've done and continue to do on the app

Just did what I think is right as far as troubleshooting goes, and screenshotted the info page on ampere. Still not getting speeds that I think are high enough, so maybe something can help getting it to work
I use the anker 40W 5 port charger as well. Ampere is reading about 380-400 sometimes dropping to 290. I have GSAM installed as well and getting similar readings. I just checked this after reading your post. I did notice my phone seems to charge slower than my M8 but I never really looked at the numbers until now.

I have a continuing problem with very slow charging even with Quick Charge 2.0 chargers. For example last night I had the M9 plugged into a fast charger for over 12 hrs and it went from 5% battery to 87%. I checked the Settings - Battery usage history - and it displays "NO APPLICATIONS FOUND" - very strange...
Something is very wrong. I have multiple 2 amp and quick chargers all with poor charging times. I have tried 4 different chargers and I tried to post links for the chargers. but the forum rules prevented it.
The Ampere app displays varying charger power from 15 mA to 880 mA so I don't think it is accurate.
Testing with multiple chargers point to the problem in the M9. This is maddening. Seriously considering returning the M9.
Any feedback?

I'm using this CHOE Quick charger and my phone charges from 60% to 100% in about 30 min
You can't just use any 2a charger it must be Qualcomm Quick Charge 2.0 technology certified, It makes a Huge difference
Yeah I know

Wow. Did you read my message? especially the part where I write that I have tried multiple chargers? In 12 hrs of charging any one of these should work to fully charge the M9 and they did not.
I have tried:
1) Anker® 36W 4-Port USB Wall Charger Travel Adapter with PowerIQ Technology for iPhone, iPad, Samsung Galaxy S6 / S6 Edge, Nexus, HTC M9, Motorola, LG and etc.
2) Limefuel USB Wall Charger Dual Port 4.8A/24W High Output (Black Limefuel L48WC) Foldable Portable Rapid Travel Charger for iPhone 5s, 5c, 5, 4s, 4; iPad 5, Air

4) Roker® 6.2A / 4-Port USB Charging Station /Portable USB Wall Charger / Travel Charger / USB Power Adapter for iPhone 5 5s 5c 4s 4; iPad Air Mini; Samsung Galaxy S4, S3, Note 3, 2; Google Nexus and
At least one of these should fully charge the M9 in 12 hrs. I have had very poor results with all of these. I wrote to find out the experience of others with the M9.
I seem to have a defective M9... dang...

The stock charger that comes in the box charges my M9 in about 2hrs30mins (there abouts) from 10% - 100%
With regards to Quick Chargers, the one that comes with the Note Edge can charge the M9 from 10% - 100% in approx 1hr30min...same goes to the Rock Tank Quick Charger I just bought

Yep i read it, and nothing in your list is Qualcomm Quick Charge 2.0 .. you can use a million iphone chargers and non of them have the chip in them required to quick charge the M9. did you check my link ?

I found that turning battery saver on but only checking the CPU option helped me. Try that to see if it makes any difference.

Guys,
12 hrs on a charger, any charger should fill the battery. AAAAND the phone is not in use at all.

Guys .. I just got my m9 and I'm having this exact issue. Ampere seems to work but it's reporting 290mA. I charged the phone overnight and it didn't get to 100%. Really frustrated by this and considering returning the phone. Even though I think it's a software issue. Have also tried a full reset and slowly installing apps to see if it's a rogue app. No joy there tho.
Any advice on this is greatly appreciated.
Try using the charger and USB cable that comes with your M9.
I am unable to charge to 100% if using chargers with 1A output. The HTC charger is as about 1.5A output.
