So the G4 comes supplied with a 1.8A output charger, and I am wondering whether it is okay to use another charger I have, which has a 2.1A output? As in will it damage the battery over time?
I have heard the G4 supports quick charging so I'm guessing in that case it would be okay.
Thanks in advance.
It's fine. The phone will charge at whatever current it deems safe, even if you had a 100A supply available.

Would it charge faster?
Maybe a little.
I get about 1600mA with the stock charger. And about 1900mA with my Quick Charge 2.0 charger, which can provide the equivalent of >2.1A. I don't have any good-quality normal 2.1A chargers available to try.
So the largest benefit you could see would be about 20%, if the phone charged as quickly as it does from a QC 2.0 charger. I doubt it would charge that quickly, personally.

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
watch this video to get all info about the Optimus G battery
https://www.youtube.com/watch?v=O7Q8E5dzyxg&list=PLShKiWbiCfxbiMFDOHnS2Y_2HzAMwsRpI&index=26
Nice tech. I liked the way they managed cpu activities besides all.
My question is that why it takes around 2:30 to charge the phone fully?
According to this: http://www.qualcomm.com/media/blog/...-charge-10-less-time-charging-more-time-doing
OG benefits from Quick charge 1.0 which should boost charging process. Is it boosted by default? Is 2:30 fast enough for a 2100 mAh battery? or it's something kernel related and should be enabled?
2:45-3:00 its the charging time and its just fine.
You can always use a bigger charger and ruin your battery faster. Or explode..

I don't want to ruin my battery bro. I'm just curious to know if other phones with the almost same specifications have similar charging time or not. I mean is this normal or not? Do you know about nexus 4 charging time? or xperia zr? these all have quick charge 1.0 while snapdragon 800 offers quick charge 2.0 and that's why phones like G2 having a battery with more capacity have under 2 hours charging time.

Well... Unless you use a charger that sets a current (extremely unlikely), it won't matter a single bit. Just a simple physics... All standard chargers provide stabilized voltage within certain current limits (that's your charger's Amp rating). The phone's battery charging circuit determines the current it draws from a charger. So, even if your bad-ass charger is capable of providing 10A output, your phone will not draw more than it needs when charging, which is about 1A (sorry, I don't know the exact charging current of the OG).

the charging current of OG is 1.2. So, you mean the phone won't be charged faster if one uses a higher voltage charger?

If you use a higher voltage charger, you could simply fry your phone -- depends on the actual voltage. The protection circuit may simply shut off the input, or limit the voltage at 5V -- I don't know enough about the OG's schematics. But it should still limit the current at the value it's designed for. Anyway, I wouldn't experiment with that... But if you are talking about higher Amp-rated charger with 5V output, then it won't charge faster, unless the lower-rated charger is actually rated lower than the phone would take. Here, just a couple of examples, assuming 1.2A nominal charging current...
Example #1: 0.7A charger. The phone is trying to suck as much as it needs, but the charger can only supply 700mA. So, it will charge slowly.
Example #2: Stock 1.2A charger. The charger is supplying just what the phone needs, which is 1.2A. So, it will charge faster.
Example #3: 2A charger (or more). The phone will still draw 1.2A, even though the charger is capable of supplying more. So, it will charge at the same speed as with 1.2A charger.
Makes sense?

Oh, I see. Thanks. But, I don't know about the schematics either. I don't know if the phone has this smartness to draw as much as it needs or just draws as much as given. So, I won't risk either.

Regardless of particular schematics, a properly designed charging circuit is always drawing the set current from a source. In other words, your phone is definitely smart enough to only take what it needs. Basically, "as much as given" in this context is incorrect statement... A charger "gives" a specific voltage (5VDC for USB-charged devices), and the device "takes" a specific current. So, no matter what the Amp rating of a charger is, it will only give as much juice (Amps) as the device decides to take (within a charger's Amp limit). If a charger can't provide enough current for the device, then you have a problem with slow charge, or no charge at all. But higher Amp-rated chargers are fine. If you have, let's say, a charger from a tablet rated at 2.5A, or a stabilized lab power supply rated at 20A, both of them would be OK to use for charging your OG. The only possible problem in this case could be a defective charging circuit in the phone, which might not limit the current the way it's designed to, and could draw enough from a high-powered charger to kill itself. Low-powered charger would simply not be able to provide a dangerous current, if that happens...
Having said that, I've got quite a zoo of various power supplies laying around, and I used all kinds of them rated up to 30Amp to charge different devices. Never had any problems.

and you've never seen any acceleration in charging time? So, it's just a common mistake that people say higher Amp-rated charger results in faster charge?
E977 battery difference?!
look at these two screenshots. one of them is E977 (in Spanish) and the battery is written to be SiO Lithium-ion. (SiO+ is used in G2)
the other is for E975 and the battery is written to be Lithium-Polymer.
Are these two the same?! Or this is an improvement made in hardware revision 1.2?

As I said before, it really depends what exact Amp ratings you are comparing... If a charger is rated lower that a phone's charging circuit, it will certainly underperform, and will charge slowly. But if your charger's rating matches or exceeds the charging current required by phone, then it makes no difference.
I personally don't have an OG stock charger, so I don't have any experience using a charger rated specifically at 1.2A. I only have USB chargers rated at 700mA, 850mA, 1A and 2A. Plus, an assortment of other power supplies rated anywhere from 2A to 30A. Of course, I do see a faster charging when going from 700mA charger to 1A, and then to 2A, because the first two are under-rated compared to the phone's specs. However, once I go with 2A or the higher rated power sources, there's no difference at all.
Hope that explains it.

Yes, the last sentence clarified it. Thanks alot mate.
need a quick help here. i accidentally left my charger at work overnight, and someone decided that its his/her's now ....ive searched around and cant find place to buy the original charger that came with the m8. HTC's website doesnt have it. amazon doesnt. even ebay dont carry it.
i need of a charger. currently using a LG G2 charger thats rated 1.8a 5v .....but with a super slow cable.
is the LG charger okay to use? will it damage my m8 in the long run?
i am also buying this cable on amazon. buy or dont buy?

yes, i know there is a quickcharge 2.0 coming out. seeing as the cable is only $5 ...im thinking it will do for now.
thanks in advance
HTC charger outputs 5V and 1.5A. As long as output voltage is same, you can use different chargers. Ampere value just affects charging time. Higher ampere means faster charge. In long term, it can shorten your battery's life, but I don't think 0.3A can cause an observable affect

I use all sorts of chargers. They are pretty much standard now as far as micro usb goes. As said some are higher rated some are lower. I don't think there is any that will damage the phone as long as its designed for charging and is 5v.
I too use multiple chargers and cables and the only issue I've had is a double length cable that works for charging but won't allow connections to the pc
XDA app on m8 running venom
I charger capable of delivering more current will not damage your phone since the phone won't draw more current than it wants.
Hi guys, the Zenfone 3 deluxe supports qualcom quick charge 3.0 however it seems to be locked to the oem charger. Any other licenced qc 3.0 charger does not quick charge the phone. How hard would it be to get around this? Mainly for qc 3.0 powerbanks.

This is not true. I am using this one - https://www.amazon.de/gp/product/B01EH11AS8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
and the quick charge 3.0 works fine. I am still using the original type-c cable that came with the phone though.
Note: Make sure that you have plugged in the USB end of the charger correctly, push it all the way in. If it's only pushed in partially, then you may not be getting the full power for Quick Charge. You can verify this by using a tool like AIDA64 from the playstore and checking the "Charge Rate" under battery.
This is where I was told it's not supported.

Update: Sorry guys, I realized that the OEM charger is indeed much faster at charging. Read posts below.
postimg.org/image/6wis1rux1/ - using licenced qc3.0 charger
postimg.org/image/ndr13s0pv/ - using oem charger.
Further test screen off
15min charge with licenced qc3.0 gives 13%
15min charge with oem charger gives 27%
Same test with screen on (playing video)
15mins with either charger yields about 15%, no noticible difference. Seems like the oem charger throttles when screen is on.
All tests are run when the battery is below 20%.
Same oem cable used for all tests.
Using the oem charger to fully charge my phone does it nearly twice as fast as the qc3.0 charger.
Don't know how your able to achieve the same speed regardless of charger
Hi guys, I've been experiencing the same problem with original charger, that's very big and it's seems that didn't have quick charge. I've a samsung charger and with samsung charger it wroks fine. I'll try to well plug thw original , but, it's thinner samssung's one.

Interesting ... I stand corrected now regarding the "Fast Charging" on the lock screen.
I never used the original charger because I bought mine directly from Taiwan which has an US plug which I cannot use here in Germany directly without an extension.
I tried the OEM charger now with an adapter and yes you are right, the Charge Rate with the OEM charger is 2 times faster than with other chargrers.
OEM charger - 2900ma charge rate
Other charger - 1300ma charge rate
---------- Post added at 11:29 AM ---------- Previous post was at 11:02 AM ----------
Actually now I'm confused. When I plugged in the OEM charger, it said "Fast Charging" for a short while and then it says "Charging". The Charge rate also came down from 3000ma to 1300ma and down to 800ma when the battery is at 90%.
I will do some proper tests with the different chargers and post back.
Confirmed: OEM charger is much faster than other QC 3.0 chargers
When the phone reaches 70-80%, the charging rate will slow down and just trickle charge. This is normal as it can be dangerous to keep charging at Fast speeds when the battery is close to full capacity. So if your phone has 80% and you put it on charge, it will not Fast charge regardless of the charger you use.

I can also confirm fast charging doesn't work with my QC 2.0 charger. Interesting thing to note is it outputs 5V - 2A and 9V -2A. My guess is this charger from Asus that fast charges the Zenfone 2 would work on our phones because it has the same outputs if you read the description. It's worth a shot and you could always return it to Amazon if it doesn't work.

Unfortunately, even though the charger referenced above has the same outputs it doesn't fast charge. Seems you can only fast charge with the included charger. At least we can use our own charging cable. If anyone gets another charger to fast charge the device let us know. It doesn't appear Asus sells the included charger on it's webpage yet.
Not allowing the standard quickcharge charger to work forces people to once again purchase / replace current QC chargers.

At this moment, I don't really think it's a CON side...
The quality of all those QC2.x/3.x charger are not even today (may get better in future, however I really doubt those cheap, knock-off charger from China). Some are good, some are outright bad. QC is quite sensitive with the voltage/current delivered by the charger (it's by design of QC, I believe) and not optimum voltage/current will shorten the battery life at best, create danger at worst scenario.
LiPo battery is really not designed to be charged in high speed. The associated temperature issues needs to be check very carefully and charge current needs to be controlled strictly to avoid dangerous thermal runaway. It cannot only be done by phone itself and need co-work from adaptor (switching voltage, for instance.) Thus an adaptor which have good communication with phone is a safety requirement as far as QC is concerned.
Same with me. I bought a wall charger aukey PA-16 and a car charger Aukey CC-T8. Using the ampere APP, The original zenfone charger gets 2800 mAh. And the aukey chargers up to 1300 mAh.
K6 charger also does not enable Quick Charge function on 570KL
Input type: 100-240V 50-60Hz 0.5A - Quick charge 3.0 output: 3.6V-6.5V-3A/6.5V-9V-2A/9V-12V-1.5A - Power: 18W
I am wondering if someone achieved any solution to remove OEM charger lock to use fast charge with third party Qualcomm Certified Chargers/Power Banks?
Sorry to resume this thread but i lost my oem charger and id like to get one that works with the zenfone 3 deluxe and quickcharge. Can anyone post a link where i can buy it or maybe the model number of the charger? The EU version would be nice.
Thanks
Any solution to the original question?

ASUS locked the fast charge function to the OEM QC 2.0 charger that comes with the phone (it will NOT work even with other ASUS QC 2.0 - or 3.0 - chargers, only with the specific type/"model" that came with the phone). Therefore we don't get QC3.0 - as advertised - at all. The QC3.0 compatibility with 3rd party chargers, powerbanks and car chargers was disabled with one of the updates, I think it was the Android 7.0 Update (that replaced Android 6.0) that removed QC3 compatibility. So... any ideas how to re-enable the QC 3.0 functionality?
Quick charge was disabled for other chargers from day one. I'm still on marshmallow (Android 6.0) and only the charger that came with the phone works with quick charge.

I don't know if you'll damage the phone but i know that the faster you charge it the faster is discharges
Wat charge you use ? Give me link ...and what time you get on full charge ?
No, the phone will just draw what is capable of. You can get a 100W PD charger and if the phone supports PD, it will charge at the maximum that i can (which will be way lower than 100W) If is no PD compatible, probably will fall down to other standards that both the phone and the charger are capable of, like QC3 or if they don't, to the good ol' ""5V 2A""
There's no problem if you use higher wattage type C chargers. You're just overspending on something your phone can't fully utilize. Your phone would still just ask what it's programmed for charging and the charger just provides power to satisfy, given that it could.
