Hardware: HK version GN+Scotland MIUI 5.18+Sony EP850 Charger(5V / 1.5A)+2000mah original battery
Measurement soft: Battery Pro
Statistics:
6/5 00:47:49am Capacity 9%
6/5 01:57:36am Capacity 57%(Currency est. 915mah)
6/5 03:47:36am Capacity 100%
Charge time(9% ~ 100%) 3hrs 13sec
Charge efficiency = (2000x(100%-9%))/3 = 606mA/h(Per hrs 606mA)
Conclusion: Charge time is shorter than original 1A charger. But not too much
difference. Since the charge circuit is design to charge at small currency at
the beginning and the end(almost 1mAh)
I will post more figures based on Nokia 1.2A charger and Delta 5V 3A charger.
Pls share urs!!
Here's a graph to show the different charge time and currency between 1.2A and 1.5A.
X-axis is time(Minutes)
Y-axis is currency(mA)
I worked on giant lead-acid batteries on my submarine, and was intimately famiiar with charge current/voltage curves like these.
Li-poly is different game, I learn something new about them all the time. Thanks!

Did you have fast charge enabled with a different kernel? I've found that there is no need for powerful chargers with Fast Charge enabled. A regular PC USB jack charger just as fast as my 1A wall chargers.
Isn't that a little too slow My phone charges super fast compared to this. And runs around 41 hours on almost standby mode.

Yes, I've enable the fast USB charge option(I'm using franco kernel 181r)
And I'm using 1.2A and 1.5A AC charger,but not USB charger.
Battery Pro reported they are all charging in AC mode.
How many amperes does the z2 support max at 5v? Since it has quick charge 2.0 I was supposing up to 3 Amps but even if I connect it to a 3Amp USB output, with the Ampere app, I can see that it takes 1.5A max
I tested with Quick Charge 3.0, It is taking 2.3A @ 5.3v
with the screen ON the maximum charge is 1.6A. you need to use an app that logs the charging history when the screen is off or use something like a USB tester to measure that.
here with the original charger I get 2.6A (5.3v) with the screen OFF.
Hi everyone,
I'd like to equip myself with AC to USB adapters to fit my A520F, but I can't see anywhere what is the norm under which the fast-charging works for that device.
I saw that USB-PD certified devices could fast-charge the A520F, and I saw that the samsung supplied adapter can deliver 9 V @ 1.7 Amps max.
Those are all hints that the A520F should be pretty much charging quickly and nicely on any USB-PD source rated above 15 or 20W, but I also heard about "Adaptative fast-charging", "IQ technology" and so-on that smells like marketing and branding.
My question is: does anyone has any more solid information on the quick-charging standards supported by the A520F ?
As far as I know, the Adaptive fast charging, IQ Techonology and others are just marketing terms. What I've read online is that even if the A5 supports up to 15W of power delivery, it usually draws less power than that.
This is an extract of an article I read about it:
When 49% charged and turned on, the Samsung Galaxy A5 starts drawing power to around 6.2 watts (8.8 volts @ 0.7 amps). When the phone is off or in sleep mode, it pulls higher current to eventually charge at about 12.3 watts (8.8 volts @ 1.4 amps).
The Samsung Galaxy A5 was also seen getting around the same power levels from other chargers like the Google 18W USB-C Power Adapter and Anker PowerCore+ 26800mAh PD while the phone is both active and inactive.
So I guess buying a 20W+ fast charger won't do much difference. Same thing happens with the Galaxy S8/S8+.

very interesting read, thanks a lot
Lots of questions here...
G7 comes with QC 3.0 although the chipset can support QC 4.0 as per Qualcomm. I see on other forums that users can tell when their phone is quick-charging or slow-charging.
1) Does the G7 let you know what speed it is charging at? I'd like to know so I can swap out cables, chargers, Qi pad, to get the fastest charging rate.
2) Is there a difference between Samsung's Fast Charging, and Qualcomm's QC 3.0?
3) If a charger says that it is compatible with Samsung S9's or S9+'s fast charging, will it fast charge the G7?
4) is there a QC Qi pad that is compatible with our QC 3.0 phone? If so, can I assume that I would still need to power it with a QC 3.0 wall wart?
5) Will a USB-PD or USB-IF charger quick charge our phones?
6) What is the minimum QC cable type (USB 2.0, 3.0, or 3.1) needed to get the maximum QC 3.0 charge? Does it have to be a 3.1 cable?
7) I've seen that when I put the G7 on my 1st gen Qi pad (5W micro-USB) that the phone screen lights up, and a circle briefly appears with the charged percentage in the center (while phone is on stand-by). If the phone is unlocked and the display is on, a white window telling me it is wirelessly charging shows up and tells me how long until the phone will be fully charged (again, when placed on a Qi pad). It's currently telling me 19 minutes to full charge from 93%. Is there a way to get this remaining-time info while cable-charging through the USB-C port?
Thanks!

The charge rate of the phone irrespective of the chargers we use, it is controlled by the stock kernel. When screen is on, it lowers down the amperage (See Ampere App) to keep off the heat, vice versa etc. We need a custom kernel to have the charging amperes to be changed manually which is really cool. If we have a really cool custom kernel, the CPU governors should preset customisable governors (for smooth performance) and for the charge values, just look for a 3A charger, with the Kernel Adiutor change the values. Meaning the benefits of rooting gives us the complete freedom of our Android! If a 4A charger is detected by the kernel manager app, the charge values should show as "upto 4A even with the screen on! Then no need to be jealous of Dash Charging of One Plus!
I think this article will help you out... Breaks it all down... Samsung charger are not the greatest for fast charging but works better than a basic one... Ultimately I would say USB c to USB c with USB PD is your fastest with QC 3.0/4.0 being a close second..
https://www.digitaltrends.com/mobile/how-does-fast-charging-work/
I don't see that wireless fast charging is b supported by the g7 ... That's a Samsung gimmick ... But the Qi standard chargers charge at the same rate as a basic charger... The lock screen always tells you how long until full no matter what charger you are using and it will say fast charging, wireless or just charging... My observations have been around 1.5 hour for 60 percent to full so about 5 hours if dead, great before going to sleep and I missed it in my least few phones

Thanks! I noticed you do not have a G7 listed as a current phone in your signature. Is your answer above based upon your experience with Samsung phones and their charging system, or specifically with the G7 (or other QC 3.0 phones)?
I hadn't notice the charging speed on the lock screen, as I have the phone set to basically bypass it all the time (fingerprint, facial recognition, & geo-fence)...so I didn't even know it was listed there on the bottom. Thanks again...now I know it's there
Strange thing is I went through a bunch of permutations with cables (various generations), and charge blocks and Qi pads this morning, and with the phone starting at 93% charged, it made no difference in remaining charge time no matter what combination of the items I hooked up. I saw the standard "charging" memo with some combos, and the "fast charging" one too, with others. Can I assume that even though the phone might say it's fast charging, it ramps the speed/power level up and down as necessary due to the current state of charge, or heat or some other factors? Would it also possibly switch into fast-charging with more power if the phone was starting at a lower state of charge, or possibly cooler?Yes, I'll have to read the link above as it's probably covered there
"Fast Wireless Charging" is supported and working.
I have a RavPower 15w and 3 umdigi 15w qi wireless pads that all say wirelessly fast charging when connected. Needs an 18w QC2-3 charger for the input voltage ranges needed to work.
It is noticeably faster than a 10w qi pad and only slightly slower than QC 3.0 USB average charge.

Of the 2 Qi pads you mention, any preferences towards one or the other (or a different one altogether)? I have an Anker QC 3.0 charger I can connect up to it.
BTW.. I cannot locate a 15W Ravpower pad. What model is it? And is the Umdigi a model Q1?

My pixel screen went bad and the charging port went bad also... Just got the g7 so I haven't changed my signature or updated my devices...
Samsung Fast charge is basically qc2 ... And standard USB A to C do not support the higher current that USB C to C does... I notice fastest charging with my pixel USB PD charger...
And yes you won't notice as much fast charging from the top 20 percent of the battery to prevent over charging...
for me, from 25% of charge, the fast charge advertisement says 1 hour and 20 minutes (charge fast???????).... if i use a normal charger (not fast), the time goes to 1 hour and 31 minutes. this phone has a charge fast but very low fast

I know it's hard from a specs perspective as most are only 75% efficient so the 10w might only be 7.5w and 15w is actually 10w, which is why LG customer services expressly states you must use a 15w QI charger for fast wireless charging. Another problem is the specs aren't always accurate and updated devices might still have old specs listed. I tried a bunch before I found a couple I liked. The mophie streampad+ also does fast wireless charging but is listed as 10w.
The RavPower is a standup charger I use in the office, the other UmDigi chargers I have scattered around the house and in the bedroom.
RavPower: https://www.amazon.com/gp/product/B079C1QLCR
UmDigi: https://www.amazon.com/gp/product/B07DJ56LT5
Did a little charge test from 50 percent
Wireless charger =1h 40m
Stock iPhone charger =1h 14m
Both pixel USB C to C and stock fast charger =1h 2m
I'm in the market for a qi charger that can fast charge my Thinq g7. I see reports of needing 15W but not seeing many out there that have that spec.
I have seen a RavPower one posted here that is said to do it but the price is quite high for that model. Does anyone else have experience with fast charging the thinq g7 with a Qi charger?
I have Samsung Fast wireless charger. This present with S7. Fast charging battery of S7 Edge, S9+. But G7 didn't support fast wireless charging. And charging is slow. So you can buy what you want but charging with this phone will be slow.
I read this topic and wondering how G7 is going to wireless fast charge?

Just thought I'd add to this - the charger that comes with the LG G7 ThinQ (Verizon) is labeled with outputs 9V/1.8A and 5V/1.8A. My old HTC 10 charger is labeled 12V/1.25A, 9V/1.7A, 5V/2.5A. I haven't tried it on the HTC 10's charger on a measuring device to see actual power delivery, but at least on the face of it, if it supports those higher voltages and/or amps, you should be able to get faster charging than with the charger out of the box.
On the other hand, faster charging may in part be why the HTC 10's battery lifetime is dismal, and not once have I thought "boy I wish my G7 would charge faster".
Anyone tried qc4.0 ?
According to some sites ThinQ is capable of 27W (9x3) charging. I therefore purchased a Xiaomi 65W charger which outputs 9x3 but the phone charges only with 15W (5x3) so wasted money.
Yes. I bought 3 different chargers and also a watt meter. When charging with screen on max amps is 1A and 6-8wattage. When screen is off it goes up to max 16watt. And it doesnt matter which charger i use.
80min for a full chsrge isnt that good. But think that lg g7 released in 2018?
Vivos IC00 something charges full in 20min. 4000mAh.
Im sick of "..reduced charging speed cause it can in a long term reduce battery......" who gives..? Then if you notice a different is gonna take 3 years and if still got same phone. Switch battery.
Look at Tesla batteries whos battery lost like 10 percent after 30000 km. I mean..come on
Im on 72% now and it says 45min to full.
A specialised site reported it would charge at 27W (9V x 3A) but this is simply not true. The best it can charge is 15W (5V x 3A). Thats it.
I have two fast charge power banks, one Anker PowerCore+ QC 2.0 and an iWalk Secretary. Neither will fast charge the Tab S4. Nor will plugging in the Tab S4 into the 3.0 and 2.0 quick charge ports on my Anker and Aukey multi port charging stations. The maximum charge (using AccuBattery app) I'm getting on these fast chargers is 500 ma and pretty up and down not really consistent. When I connect to a standard port it goes up to 900 ma without any dips. When I connect my Note 9 to the same fast chargers I'm getting 1300 ma.
Is this a Snapdragon issue?
Are you getting 800+ ma charging consistently with your power bank? If so which one are you using?

i never ever charge via fast charge as it destroy the battery in the long run, but i own an Belkin 15000 milliamp power bank.. i have just switched on fast charge for you I’m getting 1375ma charge that’s what AccuBattery is saying I’m averaging that of my power bank..
I hope that answers your question? pp.’s never i have heard of iwalk bit of advice avoid unknown brands! Anker is good but I don’t know about iwalk, get the Belkin one that I own.. I have charged my Note 9 twice in the last few weeks once full and once around 70% and I have charged my Tab S 8.4 LTE fully once and I still got 3 led lights left on the Belkin power bank..
Mate this Belkin power bank is a beast!
I will have to install accubattery but I have a Anker PowerCore 20000 with Qualcomm Quick Charge 3.0 and it works pretty well for what I need. but looking to upgrade to more power but smaller in size.
https://www.amazon.com/Anker-PowerC...re+20000+3.0&qid=1550676139&s=gateway&sr=8-13
These tabs support QC2.0 which allows for a theoretical 5V/2A or 9V/2A. In practice I've never seen it above 9v/1.7A. Does your accubattery app actually indicate the negotiated voltage? Or just the amperage?
The only way I've found to reliably check chargers, cables or devices is with a hardware ammeter like this:
Mini USB Tester DC Digital Voltmeter Ammeter LCD Display Current Voltage Meter Detector Power Bank Charger indicator Amperimetro
https://s.click.aliexpress.com/e/3rPyJb6
I've got one like this (reads 9volts despite the spec sheet stating otherwise):
