Not sure if this is an issue, or if its standard. But here is what im facing.
A charge off the wall will get my Tmobile SGS2 to a full charge (from around 15%-20%) with the stock plug and cable in about an hour to an hour and a half. However charging from my laptop or from a car charger im only getting a total increase in battery 15% in an hour. I tried to use the stock cable with the laptop and got about 25% in an hour and a half. I tried to use the stock cable in my car and only got 7% in 45 minutes.
Anyone have any ideas?
When charging from the car or from a laptop, the power is limited to what the cable/charger can supply which might not be sufficient for the SGS2. For the car charger, you can try buying one that supplies more amps, but for the laptop, theres really nothing you can do, as it is limited by the USB cable itself.
Do you mean the USB cable or do you mean the actual plug & internal workings of the laptop? because i have tried several cables. And just also remembered that i tried the stock cable as well with crappy results.
you can buy a 2A charger, and it will charge a lot faster, that's what i use in my car
at home or office, i just use the regular charger, as i always carry extra battery packs
When you plug it into the laptop it only gives out a limited amount of amps unlike the regular charger that came with the phone. The one that came with the phone regulates the charge so that it doesn't overcharge your device or anything. The laptop USB plug is supposed to be meant for peripherals like a mouse and stuff so it doesnt give out that much amps, therefore charging slower than a regular charger.
I use the t-mobile rapid car charger, It can charge this beast in about 45 minutes. It also has a 2nd port for a 2nd device.
Deebo took your bike too?
Really?! I've never seen my charging current go over 700 mA, even with a 2 amp charger.
I'd happily give up some long-term lifetime for faster charging.

They have a home charger too that's a home charger plus car charger in 1. I use them in the cars but they're great for trips cause you have a 2 in 1 charger.
With 3 batteries and a external charger though, I never need a home charger and haven't even put this on a charger yet.
Just as most of the others have said here, the charge is going to be limited to what the source can put out. If you get another charger (2A charger) then it will be able to charger faster but you also want to be careful with using after market chargers there are some that can negatively affect your battery by overcharging which is when the phone gets fully charged but the charger does not ever stop with the flow of power to the device.
Ok Thanks all.
Guess i need a new car charger and something for the office.
Also did some crawling through "Mother of all battery life" thread found some good ideas there for making this thing last longer on the charge its got.
Im having the same problem my fone takes forever to charge...im pluged into the wall using the charger in the box n it took me no joke 7 hours to charge my fone!
Im on it rite now as its plugged i to the wall n im losing power instead of charging...i tested the voltage n its fine ...is tgere anythin i can do?

I, myself, actually haven't used the OEM charger that came with the phone. Although I did notice it is quite small and the phone battery is a 1850mAh (larger than normal) that might affect the charging rate. I am currently using the old HTC charger that came with my Sensation and it charges fully in about 2 hours. If you want a charger that charges your phone in an hour and a half, I recommend going into a T-mobile store and grabbing the Wallcharger they sell. It charges 33% faster than OEM chargers and does not harm your device nor kill your batteries.
You can find it by clicking here
Exactly same problem as OP.
OEM wall charger charges phone to full in couple of hours but laptop USB or car USB is doing at 10% / hour assuming you don't do anything on your phone but just leave it there to be charged. Otherwise you'll be losing battery rather than being charged.

As explained in previous post, this is due to limitations in the laptop USB drive and depending on what car charger you have, the phone might suck up more juice than it is able to provide.
so this is nothing a kernel or any other tweak can fix?

Yes, or if you have like an old microUSB charger from HTC or another Samsung phone (Samsung Vibrant) you can try using those.
the 2A chargers from BlackBerry are the best
So, you guys are seeing the phone draw over 700 mA (when the charger is capable)?
If I use my iPad charger (2A), I still top out at 700 mA, and the ~4 hours that go with it. :/
Even my 1A car charger tops out at 700 mA, that's why I thought it was a hardware issue.

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.
Until now, I be been using whatever cheap 1A car chargers I found on eBay. They show up as AC on the phone, and charge acceptably fast, definitely better than USB, but worse than the original AC charger.
With GPS usage (sygic, 3d acceleration, full backlight, GPS, speaker, and mild CPU usage) the battery actually drains while charging. Starting a 4 hour trip with 100% charge resulted in 40% of battery, even if it was charging on the whole duration of the trip.
So, this summer I'm going to do some bigger road trips. I need a car charger that gives enough power to charge while doing the GPS usage described above. I suppose I'm going to need a charger that gives close to actual 2A, not only in theory. Any suggestions?

that is due to the fact that your phone only requests 500mA from the car charger (while your phone uses more)
are you using a custom kernel?
I use ElementalX, which has the option to enable fastcharge, which boosts it to 900mA (enough to charge with everything on)

Is there any downside to enabling fast charge. No sure if there isn't why every kernel doesn't enable it by default.

Because in theory USB ports of e.g. laptops only give 500mA. I've used it on a lot of car chargers, USB hubs, desktops and laptops and never had any problem.
Even if something were to break, it will be your car charger, because your phone can handle a lot more than 900mA, and if your car charger is rated for 1A that will suffice.
Actually the N5 stock has Fast charging enabled. The problems usually are most commonly from poor USB cables and sometimes bad chargers that don't output what they say. If you are dropping battery charge that quickly from a 1A charger most likely you have a problem with one of the 2 I mentioned above. DL CurrentWidget from the play store. Set the Update Interval to 1 sec and then plug in the charger. IF it is a 1A charger you should get just under 1A maybe about 900mA or so. Since you are losing battery life while charging and using the above things you mentioned I would imagine that it is getting about 500mA or less.
Try the test with your OEM cable from the N5 since it is more likely to be better at handling the higher current charge rate. That way you can figure if it is the cable or the charger itself.
Here are ones that MmmmmBacon suggested in his Cheap Charger thread. I am probably going to grab one myself.

Highly recommend this. It can charge two N5s at full speed with no issue.
Sorry for the late reply... I didnt have time to even read the replies till now.
I never believed that a cable could make that much of a difference, but testing right now with the original LG AC charger and misc USB cables the difference is immence. Best performance I managed to get was from the included cable of my Anker powerbank. its around 980-1010mAh constantly, vs the 400-600 most cables do.
I will test in the car ASAP.

http://www.amazon.com/Anker®-Du...er+car+charger
That is one of the best car chargers I've found, I use to charge my Nexus 5 when I'm on the go.
This Anker charger solved it.
It gives a steady 1000mA that is enough to charge and use GPS.
I have to give a huge thumbs up to Anker, because together with the car charger i also bought the Astroslim 3 6000mAh powerbank, which charges two devices the same time, at a steady 1500mA each!!! I loved bothe the car charger and the powerbank, definitely worth their money.
Hi all,
If I use the standard charger it always fast charge my phone.
If I use one of my two Anker Powercore+ 10050 quick charge 3 I have strange behaviours.
Sometimes the phone says charging and sometimes it says fast charging.
I don't understand why. It is not something related to the current charge of the battery.
Do you have some info in this regard?
Thanks
No one can help here ?
It also happens to me. I found out that high quality usb type-c cables will always fast charge, provided you use a fast charger. Medium or poor quality cables will fast charge only occasionally.
I have high quality cables at home and no one charges this thing correctly.
I NEVER was able to get a steady fast charge with a third-part charger.
I tried a Raw Power with high quality cables, and, even if the charge is flagged as "quick", the "Current Monitor" app shows me that it goes never past 1500mA, while the original charger can get double that amount.
I guess the Nexus 5x is just REALLY picky with third part chargers and cables
I would go as far as to say that even the original charger only delivers >2 amps of charging under 20-30% charge. After that it bumps down to 1.8 amps. over 70-80% it goes down to 1.2-1.5 amps. Over 90% it drops below 1 amp while still saying it's "fast charging".
Get an app like ampere and monitor the charging proces. If it keeps above 1,5 amps up till 80% charge you're not missing out on much charging time as compared to the original charger. Don't be fooled by the phone saying it's not fast charging.
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.

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?
Sent from my LM-G710
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.
