[Q] E975 charger limit on amps?

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.

Fast Charge

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.

Thanks for the information

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.

It would be nice to remove the red light when the phone is charging. Maybe it's something that can only be removed after rooting?

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.
One tick to the CONs side of the evaluation.

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.

how to get more speed charging?

hi guys,
i have two chargers,
1. output 9.0V 1.67A or 5.0V 2.0A
2. output 5.2V 2.4A
and a usb-c cable, in the cable box i find that this cable is supporting for fast charging and support to 2.4A but when i tried it with the two chargers, and test it using 'ampere' app i got max to 1010mA with both chargers adapter ! even with this value i feel it charging my mobile quickly, and in the bottom of the lock screen i see 'charging rapidly' but i want more and why the phone is not charged depending on the values in the chargers (1.67A - 2.0A - 2.4A) and cable (2.4A)

The P2XL charger is 9V, 2A or 5V, 3A. Your amperage values are too low, which may explain why you're not charging as quickly as you should be. The solution: get a charger that equals or exceeds the stock charger ratings.

You realize slow charging is better for the long-term life of the battery, right?

Considering we often get new phones every 2-3 years, you won't see much of a degradation from rapid/fast charging.
Rather, you'll see a degradation from charging from <15% to 100% (which people do often). That will be a more significant reason someones battery will lose much off its lifespan.
I wish Android would have a built in limiter. I'm sure in the next few years, both iOS and Android will.

After seeing this I checked accubattery and it also says mine normally charges between 700 - 1010 mah also. I didn't even think about fast charging, I don't have the original charger but I have other "fast chargers" that don't seem to be doing their job either.

There's nothing I can help you guys with. All I can tell you is what ratings your charger should have, based upon the information printed on the pair of chargers I received with my device when I purchased it directly from Google. If you have a genuine Google charger and the P2XL is still not charging fast, contact Google.

I thought that charging capped out at roughly 1000 mA when the screen is on to protect the battery from overheating/putting too much strain on it. Which could lead to degradation of the battery. That would explain why you only see 1010 mA on Ampere - because the screen is on. I don't think Ampere measures while the screen is off, so it is difficult to say what value it would be giving you.
That is my experience even using the stock charger that came with the phone.

There is one other thing that you must also have. The Pixel does NOT support Qualcomm Fast Charging. It uses Power Delivery, not Quickcharge Technology. So if you have a charger that is labeled QuickCharge or a Moto Turbo Charger you will NOT get fast charging from these units. It has to be a Power Delivery charger with a USB C port and the cable must be USB-IF certified. If you don't have all of that then you don't get a fast charge.

That makes sense then, it seems like everything gets more complicated every year.

I just purchased one of these from Amazon. Note that it supports Power Delivery 3.0. This unit quick charges my phone. The Moto Charger I have for my old Moto G5+ which is a Qualcomm charger will charge the phone but only at slow speeds.

Try any type from Anker. As long as it has qualcomm fast charging, it is fast enough. Only a couple minutes behind stock samsung charger.

Edit From My Post Below. As I looked more into this, my wall charger that came with my phone is just a small 25w box EP-TA800 which I don't understand why accubattery says its getting 5,000+ mAh from it but needless to say the baseus car charger below is able to supply the 25w means while my Anker charger doesn't https://www.amazon.ca/Anker-Charger...rger&qid=1575374418&smid=AREE309N4XPXI&sr=8-5 . It looks like I need a new cable to make this 45w thing to work, if it even works with baseus. but still better then the pixel 2 xl 16.3W charging speed. But even if one where able to achieve 45w charging speeds. It would only be good for the first %50 the rest cuts down in speed.

Provides the full 5 Amps just like the one that came in the box with the phone. I even got the baseus red 2m usb-c cables. I'm not sure if its a fluke or if there any good at all.

The charger said 26.2V, 9.32V and, 2.75A and its able to support 15V at 3A and 20V at 2.25
Supplying 24V to the Baseus car charger, it only supplied 9.32V X 2.75A = 25.63‬Watts which is about the same just using 12V
My current cable only supports PD 2.0 60W, 3 Amps
The 100W cable says it can do PD 2.0 with Gen2 https://www.aliexpress.com/item/329...chweb0_0,searchweb201602_6,searchweb201603_52
Not all cables are the same. But i'm calling this as a good 25Watt charger with cable combo just untill it burns out

Its pretty crazy that Samsung chose the latest PD 3.0 variant with PPS, requiring the odd 10V at 4.5A. Clever heat management, but until now I came up empty finding the exact supporting charger other than the Samsung original who also seems to have its challenges. This article is pretty clear https://www.gsmarena.com/dont_just_..._for_the_samsung_galaxy_note10-news-38837.php
Not that I really would want such a fast charger to become my daily driver, fearing added wear on the battery, but for the rare occasion where I really need juice and do not have a powerbank handy, following if the community finds any solution.

Question Warp Charge 30 not working?

Has anyone got warp charge 30 / 30w charging to work on their 9 pro? When I look at the charge speed using #8008 and logging the charge current with the screen off I never get over 1.2A or 1200ma. That is with the car charger and wall charger from one plus. My 65w charger will charge over 6A fine with the screen off. I tested the 30w chargers on my oneplus 7 pro and they work fine. I also noticed if I use a charger designed for PD my phone will charge at 2.0A / 2000ma. I find it strange the phone won't work in backwards compatibility. I actually get faster charging from my oneplus 5t charger that was only rated at 3.5A.
If anyone has a solution please let me know.

Because warp charge 30 can only negotiate up to the max of 5v. The warp charge 65 is 10 volts. The 9 pro phone uses a split cell battery which effectively splits and halves the incoming voltage and amperage for each cell so 10 volts become 5 volts each which would explain the much less than ideal charging speed.
Coincidentally USB-PD also can negotiate higher output voltage (I believe 9 volts) hence the compatibility to work with them.

I had considered the the 5v vs 10v but I thought one plus had mentioned the phone was fully backwards compatible. I really need to find a car charger that can charge the phone fast. I thought about buying the 50w OPPO charger but I cannot find one from any reputable place or even oppos site for sale. Right now I use my inverter in my work truck. If I could actually charger at 30w that would be fine for my needs but when using hotspot or GPS the phone doesn't even charge much at all when it only draws 1.2A. It takes multiple hours to charge 50% at that speed.

I had considered the the 5v vs 10v but I thought one plus had mentioned the phone was fully backwards compatible. I really need to find a car charger that can charge the phone fast. I thought about buying the 50w OPPO charger but I cannot find one from any reputable place or even oppos site for sale. Right now I use my inverter in my work truck. If I could actually charger at 30w that would be fine for my needs but when using hotspot or GPS the phone doesn't even charge much at all when it only draws 1.2A. It takes multiple hours to charge 50% at that speed.

Never on the specs on the official product page for the warp 30 charger states it works with the 9 pro. Just settle on any 45+ watt usb-pd adapter and it'll get pretty close to warp 30 charger's max speed which would get you topped off in roughly an hour or more. Save yourself the headache and be grateful that's even an option as past OnePlus phones would only cap at 5 watts on any non OnePlus fastchargers.
PS, I wouldn't trust any marketing fluff coming from OnePlus as of late, they've been clickbaity and false hype inducing with bold but cleverly misworded claims since the inception of the 8 series and has been going downhill from there. My 9 pro is likely going to be my last OnePlus and likely last forray with android phones as a whole.

On the other hand..., wireless warp charger 30w from OnePlus 8 Pro works fine on my OnePlus 9 Pro.
I use it untill i got my 50w warp charger.
