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.
Is this the highest?

There are 2.1A usb adapters, but I don't think microUSB can take advantage of it. The one you linked is a 1A, which is the same as the wall charger HTC gave with the phone. I'm currently using a 1A usb adapter in my truck.
Ok that's probably what I'm looking for then. Are there wall chargers greater than what came with the phone that I can take advantage of?
Your best bet would be to try the USB adapters made for iPads. The Apple products can utilize the 2.1A chargers with their sync cables, but I'm not sure if a microUSB cable can though. I have some 2.1A wallchargers from some of my Apple products, I'll test them later and let you know what I find out.

I just got an Enercell from Radio Shack with dual usbs. Max output is 2.5A divided between the two ports.

The Motorola rapid chargers rock.
Guys, unless you mod the usb adapter 5V spec, you aren't doing squat with a "high power" adapter. The device has an input impedence that will draw a certain amount of current at 5v., and that's it.
Standard battery: 1400 mAh
Time to charge: 4 hrs (according to manual)
That's 1400/4 = 350 mA.
Most adapters on the market spec more than that, they're usually 500 mA or above. And again, unless you boost the volts, you're not going to be able to push more than 350 mA or so.
So don't waste you're money.
On the other hand, if your going to share a car outlet with another device like mp3 or ipod, then yeah, you'll need a higher output, two port, adapter.
Edit: It just occurred to me that if you're using the phone heavily while charging, then yeah you may need more than 500 mA. My currrent widget shows the phone can draw another 250 mA or so during use. That plus the charge totals to around 600 mA. But depending upon design, the phone may not be able to pull in all 600 mA. A test with a current meter would be real interesting.
The charger shipped with the Thunderbolt is a 1 Amp charger.
If I use a 500 mA charger the Current Widget shows a +450mA charge current. However if I use the 1A charger, I get a charge current of about +850mA.
Given that the google navigation gobbles over 400mA when running, you need a car charger with greater than 500mA capacity of you want the phone to charge at the same time.

You're making the incorrect assumptions that the charging rate is constant, and charging is 100% efficient. Li-ion batteries can be charged at up to a 1C rate (i.e. 1.4A for a 1400 mA cell). Add the power drawn by the phone itself, and a 1.8 Amp charger might not be unreasonable (1.8 A is the specified limit for micro USB connectors). Whether the phone will actually do a maximum rate charge, I don't know.
This, from a TI Application Note (Google for SLAA287, board won't let me post links):
A Li-Ion battery charging process consists of three stages:
· Slow Charge: Pre-charging stage using current of 0.1C
· Fast Charge: Constant current charging stage using current of 1C
· Constant voltage charging stage
During the slow charge stage, the battery is charged with a constant low charge current of 0.1C, if the battery voltage is below 2.5V. The slow charge stage is rarely used during the charging process of a Li-Ion battery.
The fast charge (constant current) and constant voltage charging are the most important stages during a recharge process. Most Li-Ion batteries have a fully charged voltage of 4.1 or 4.2V.
The battery is first charged with a constant current of 1C until a battery voltage reaches 4.1 or 4.2V. The firmware continuously checks the charging current by sensing the voltage at the current sense resistor (Rsense) and
adjusts the duty cycle of PWM output from the MCU. The battery's voltage is checked frequently.
Whenever found the battery's voltage reaches 4.1 or 4.2V, the charger will switch to constant voltage charging mode. The battery is then charged with a constant voltage source at a fixed battery voltage of 4.1 or 4.2 V...When the charging current falls below 0.1C, the charging process must stop.

I suspect you need to find one which properly follows the USB Battery Charging Specification. That link is to the most recent version, which came out on 7Dec2010 (remember Pearl Harbor!). Version 1.1 is easier - a Dedicated Charging Port is indicated by shorting together the data lines (the two middle conductors on a full sized USB connector. By doing so, it indicates the device may try to draw up to 1.8 A of current (although a dedicated charging port is allowed to limit the current to less than that, it must provide at least 1.5 A).
I bought a cheap USB hub with 5 ports, used an exacto knife to cut the traces going to the data lines (the middle two) on all the ports, and then shorted them together on each port. It's now no longer a USB hub, but a USB charger with 5 ports I can used to charge stuff (phone and Bluetooth, quite often). The AC adapter which it came with does 2 Amps. My Thunderbolt says "Charging (AC)" when plugged into it.
So, if you can open up one of your adapters, just solder a jumper between the middle two contacts (make sure they're not connected to anything else).
Just got the Rocketfish premium microUSB at Best Buy and it has a captive coiled cord and a USB port. TBolt says "AC plugged" and reads +670 mA.
Good choice on the Motorola Rapid Charge - I've burned through 3 other cheap car chargers trying to keep my phone alive while using Google Nav and this is the first one to work!

+1 Works great! Battery widget usually shows about +800mA while only charging. Real close to the wall charger
Is there any kind of indication on the phone that Qualcomm quick charge 2. 0 is active when it is connected to a certified charger?
I bought both in AC and DC certified charger. both were very highly rated on Amazon. The AC charger for example is made by Anker.
The app Ampere reports a low milliamp rating of around 250mA when I am using either of these two chargers.
When I connect two different chargers that are not quick charge 2.0 certified then Ampere reports a charging current of upwards of 1800mA.
I suppose the issue could be Ampere, that it doesn't know how to measure when the quick charge technology is present. Does anyone have any direct experience with this to know what the issue is?
When I use my 2.0 Charger I can go from dead to full in about an hour. So yeah i'd say it's active!
Even with a QC 2 charger, you won't see high charge rates unless the battery is low. All chargers will slow down as the battery charges. That's just how they work. I have also seen cables make a difference. I have some right and left angle cables from Star tech that will only charge at one amp. Samsung and HTC OEM cables will allow charge rates above one amp. Finally, most programs display the charge rate after subtracting the power that the phone is actively using.
Ex, your charger is 1.5 amp, the phone is awake and playing a game taking 800 milliamps, at full power you phone can only charge at 700 milliamps as that is the charger's maximum output.
Deleted, issue sorted.
The charger supplied with phone is not quick charge compatible.
(At least in UK )
HTC do sell a quick charge 2.0 compatible charger as an accessory.

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.

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.

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:

I've got one like this (reads 9volts despite the spec sheet stating otherwise):
