is the samsung quick charger the same - HTC 10 Questions & Answers

purchased a insurance replacement from flebay it came with a samsung quick charge plug ,is this the same as a htc quick charge or shall i buy a htc type ?

The Samsung Quick Charger I believe only supports QuickCharge 2.0 while the HTC 10 is QuickCharge 3.0, so it will get the job done just not as fast as a 3.0 Charger. It pulls 5v while the HTC charger can pull 5v, 9v, or 12v.

It should be ok but the only difference is the 2.0 will charge a little bit warmer. Should be relatively the same speed as 3.0 but just get a bit hotter. So there shouldn't be any issues

Quick Charge 2.0 and 3.0 both charge at the same maximum speeds.
The difference between the two of them is that Quick Charge 3.0 allows for smaller drops in voltage as the battery get more full, allowing the charger to remain closer to its maximum charging speed for longer.
Instead of dropping right from 12V to 9V as the battery fills up, it drops from 12V to 11.8V to 11.6V etc.

[Q] Charging Speed - Different from a/c than from USB?

So I was wondering: is there a difference in charging speed between the a/c wall charger and charging from my computer's USB port? Also, what's the difference between different chargers? For example, the Desire comes with a charger that puts out 1 amp. My girlfriend's BlackBerry has a micro USB charger as well, but the output is 700 mAh, or 0.7 amp. I've seen chargers ranging from 500 mAh (0.5 amp) to 1200 mAh (1.2 amp). How does this equate to charge time? Does it even? Or does the phone regulate the charge rate?

You've pretty much answer your own question!
The current supplied by a charger/USB port determines how fast it can charge the battery, which is why the wall charger (1amp) charges much faster than a PC USB port (0.5 amps).
Regards,
Dave
It's almost completely logical.. say you have a 1.5A battery (1500mA) and a 500mAh charger (ie USB) then it will take 3 hours for it to charge but with a 1000mAh charger it will take an hour and a half.
Can't really explain it more than that, so hth.
Well , Yes and No
This is only partly true ......
If you charge it on the PC , max output is 0.5 amps , and data is possible while charging .
Now with Desktop and car charger , the amp can be anything the manufacturer likes but you have to keep the following in mind :
USB Specs state the following :
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
In Battery Charging Specification,[32] new powering modes are added to the USB specification. A host or hub Charging Downstream Port can supply a maximum of 1.5 A when communicating at low-bandwidth or full-bandwidth, a maximum of 900 mA when communicating at high-bandwidth, and as much current as the connector will safely handle when no communication is taking place; USB 2.0 standard-A connectors are rated at 1500 mA by default. A Dedicated Charging Port can supply a maximum of 1.8 A of current at 5.25 V. A portable device can draw up to 1.8 A from a Dedicated Charging Port. The Dedicated Charging Port shorts the D+ and D- pins with a resistance of at most 200Ω. The short disables data transfer, but allows devices to detect the Dedicated Charging Port and allows very simple, high current chargers to be manufactured. The increased current (faster, 9 W charging) will occur once both the host/hub and devices support the new charging specification.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
So if your Desire ( Yes , the Desire supports these specs ) detects the short , it will switch to fast charging mode otherwise it will limit the charging current .
Unfortunately , there's no way to know , just by looking at a charger, if it respects the specs or is just a low cost 5V powersupply . I've encountered quite a few ( mostly lowcost) desktop and car chargers that are rated between 1 and 2 amps , but still take bl**dy ages to charge the phone . Checking those with a measuring tool , you usually see the data pins are "Not Connected" instead of being shortened :-(((
Final Word .... don't try to save some money on a cheap charger , you'll regret it Genuine HTC works great , others do the same , but don't expect a $1 charger from Hongkong or whereever to do it !
These are the theoretical specs. Keep an eye on charger efficiency ratings and battery charge absorption won't be 100% in any case. Also bare in mind the charge is not linear, it will trickle after approx 80-90% with this phone.

Ya, I noticed the charge slows down considerably for the final 10-15 %
I find myself charging my Desire more than I actually use it, lol.
I found now the answer to this problem: I use a Nokia charger (5v and 890 mA) with a microusb adapter. You can find one on eBay at ~2$
Now it takes about 2 hours from 20% to 100%
Lets hope nothing wrong happens to my precious Desire
look here for a method to charge at ac speed from usb, explains a few things too.

[Q] What is the maximum mA can the mini handle when charging?

Hi guys,
I've noticed that my galaxy s4 mini 3g comes with a 1000 mA (1A) charger and it charges at a very good speed compared to when I plug it to an ordinairy USB port (500mA only I believe) on the desktop.
It gets warm after a while while charging using the official samsung wall charger (1A)
I plugged it in my battery bank where the output is said to be 1500 mA and it charged up much faster but gets a little more warmer in the back.
I have an ipad charger here rated for 2.1A but I haven't tried it yet..
I want to find the fastest but also a safe way to charge my phone in order for the battery life to become longer before I need to buy a new one. So I want to ask you guys here in the forum what chargers do you use?
A good read that made more familiar with charging via USB:
http://www.extremetech.com/computing/159727-how-to-charge-your-smartphone-and-other-usb-devices-as-quickly-as-possible
For the battery life to remain long you should stick with lower amperages. The 1A charger should do you fine. USB ports are typically 0.5A, unless its a USB3 port which gives more amperage I think.
I've used a Mega 6.3 charger on the S4 mini before (2A).

Will a 2.4a powerbank charge the M8 as quick charge 2.0?

I've just bought this https://www.amazon.co.uk/EC-Technology-External-Flashlight-Smartphones-Black-Red/dp/B00ZZ6DFLA
Should I expect it to charge as fast as fast charge 2.0?
Don't know if this applies to the power banks, but a charger will only take full advantage of QC2.0 speeds, if it has the QC2.0 name and/or logo on it. Although an non-branded charger with higher amps may or may not charge somewhat faster (but not as fast as a certified Qc2.0 charger); http://www.ubergizmo.com/2015/06/qualcomm-quick-charge/

Quick charging questions - LG G7 ThinQ

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.

What power bank are you using for fast charging on your Tab S4? QC 2.0 not working

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):
| LCD USB Detector Voltmeter Ammeter Mobile Power Charger Capacity Tester Meter Voltage Current Charging Monitor 3V-7V DC 3-7V
