For those of you who have tried the wireless charging mod for the T889 version of the SGN2, do you get a voltage drop across the receiver coils with the phone not charging on the Touchstone but powered up? What about NOT charging but powered off? I'm just wondering if the missing hardware controller shuts off power to the receiver coil when the phone is not in wireless charging mode. Do you notice a drop in battery usage time or no drop at all?
Anyone have access to the N7100 version that can verify this?
I'm contemplating applying this mod, but I also want some control over when the receiver coil is active. [I was hoping to post this under the developer thread started by Vinas1, but don't have posting rights to that area yet. I need to pay my dues with 10 posts]
Wireless charging is not much current. I think around standard usb current which is 500mah. The stock charger is 2000mah (2amps). So that means when in wireless charging if you have the screen on it will most likely not charge but keep it at whatever percent it is currently at. If you are doing anything else as well like GPS you can expect it to drain on wireless charging.
Hello everybody,
I have recently bought the Griffin Dual USB car charger.
I use quite often a GPS navigator when I am driving, so I wanted to buy a car charger which was powerful enough to sustain gps and 3g data plus a little extra juice to charge my phone battery. I found this charger on the internet and the specifications say it's got an output of 1A which should be more than enough for my needs. However, I was quite surprised when I realised that the battery still goes down really slowly when I use the gps app.
I've had a look online and apparently most car chargers are not recognised by your phone as a proper charger. For this reason, they provide only 500mA. You can double check this by having a look at 'settings > about device > Status > Battery status'. If it says 'Charging (USB)', it provides 500mA. Instead, if it says 'Charging (AC)', it provides more (so called fast charging). Well, my phone says Charging (AC). But it's still not enough apparently
Do you guys know any app or anything I can do to test how much the charger is actually providing?
As you can imagine, this is quite annoying.
Thanks
i'm in the same boat as you but a different dual USB Charger
It's suppose to output 2.1A + 1A or something along those lines and it does charge last generation iPad and an iPad Mini at the same time without an issue.
When I plug a Galaxy Nexus in it charges as a USB BUT when I plug the Galaxy S3 it charges as AC but a 2 hour trip only got my phone battery up to 47% which is way way too slow and that is without GPS
The AC charger that came with my phone only outputs 1A but it charges my phone in 2.5 hours from dead flat to full
My car charger is the same. 2.1A port for tablets and stuff. 1A port for everything else. I have noticed that if I plug my s3 in the 2.1A port, it charges slightly faster. However, it's not even close to my 1A wall charger.

Hi, if you are looking for a best usb car charger for your device then i have a option for you. Please check my profile and fo to the link in my bio.. Thank you
I recall back with my old phone (Virgin Mobile LG Optimus V), the lead devs teamed up and made a flashable patch that allowed you to toggle fast charging on and off, basically telling the phone whether it should consider the power source a USB or Wall charger and it worked good. Maybe we can get some people to team up and build that for the S3?
Any way to force fast charge when charging via USB
When charging with wall outlet with original LG charger the phone charges pretty quickly.
However when charging via USB in my car there are time it will charge slowly (which I can deal with) but there are other times it will not change quick enough resulting in the battery actually losing charge. What is weird is I can't figure out the variability as the load should be pretty consistent (screen on, bluetooth on, GPS on, car home ultra, navigation and stream music).
I had a Galaxy Nexus that had the same problem but was able to resolve it with combination of using a power only USB cable and custom kernel that support Fast Charge which I set via Trickster MOD. I am using the same setup except I can't find an equivalent way to trigger Force Fast Charge.
I am using GSam Battery Monitor to try to diagnose but am getting confusing results. The mV reading varies from time to time from -1000ish to +1300ish.
Is there a way to solve my problem?
Thanks in advance!
What is the rated amperage output of the car charger and have you tried using the original LG cable with it?
If the port on your car isn't putting it enough amps it will never fast charge. Try getting a fast charge car charger.

Hum... I didn't think about checking the output of the car charger. Thank you for the suggestions. I think that is the problem.
I have a GoGroove FlexSMART X2 Mini (http://www.gogroove.com/GOgroove-Fl...eless-In-Car-Bluetooth-FM-Transmitter-pid9385) and I found out its output is rated as DC 5.0V 600mA. I think I'm going to need to get a twin socket adapter, one socket for the X2 mini and one socket for a fast charge car charger.
Buy a 12VDC charger with at least a 5V 2A output and you should be good.
Hi there,
so i was wondering if anyone has this problem which i have. Recently i installed Ampere app and checked why my chargers aren't working as they suppose to. I have 2 chargers, one original 1,2A and one 2,1A. Also there is one car charger which can use 1A and 2,1A current.
I checked with Ampere and in max. USB curr. i have 900mA. Is it something not normal in E975 or maybe this phone has limit? For less than second after connecting USB cable from charger i see 1500mA in this box and then it changed to 900mA. From calculations it seems 900mA is max (charging around 2,5 hours).
My question is: do i have broken phone or charging is really limited to silly 900mA? Is there any solution to increase that current limit?
the app lies... the phone draws 1.2
So, using 1,2A charger and good cable should be enough to charge it as fast as it is possible? What about using "bigger" charger like 2,1A? From my experience it doesn't speed up whole process but maybe i have some ****ty chargers...
tried with a lg g3 charger (1.8A) and the tool i have to measure ampere showed allitle less! but maybe the tool said wrong... who knows...
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.
