does it use qc 3.0 or a LENOVO proprietary standard? read here.... - Lenovo P2 Questions & Answers

from gsmarena:
We initially thought that the Rapid charging tech used by Lenovo must be Quick Charge 3.0 since the P2 uses a Qualcomm chipset. However, our third-party QC3.0 charger didn't charge the P2 particularly fast, so the jury is still out on whether Lenovo is using a proprietary charging technology.
so... my car charger and my power bank, BOTH qc 3.0 are useless with this phone??

Our charger is a basic 12V 2A charger, giving a total of 24W Power. I don't see anything special in the charger. It's probably not the usual QC we had heard of. I have seen in some reviews though about this charging technology being different and very interesting.

A problem would be: what charger for the car???

i have the phone and i can confirm it only uses the QC feature with the included CHARGER
no way to use any qc 2/3.0 charger....mmhhh bad decision lenovo!

I don't see your point. This charger outperforms any other chargers in the market even turbo and dash chargers.
Why do you ppl always end up blaming others.

because i am against the proprietary charging algorithms..... dash charge is great? NOPE.... it forces you to use a special cable, a special charger, no 3rd part suppliers... high price of chargers, is it a good move for the customer?
same thing for this lenovo charging solution, ok the fastest one, but if i lose che official charger i am stucked with the NORMAL 5v 2a solution....
this is not a great thing imho, and all power banks i have qith 7/9/12v qc features are USELESS with the lenovo p2......

You're thinking only voltage my friend, check if your power bank can supply 2A at 12V. Probably no. Mostly all power banks bottlenecks at 1.5A.

So, there isn't a way to use another charger for fast charging?

my xiaomi power bank 2 20000mah does have qc3.0 and it's tested to arrive higher than 2A at 12v ... but even if other chargers are "only" capable to reach 12v at 1,5A ... it is still a missed quick charge because p2 uses proprietary charge coding
ok this is not THEp roblem, but just a con. like for dash charge people repeat at eveyone that oneplus is the fastes... but hey without an available dach charge power bank... that phone is s "joke"

I have another QC3.0 wall charger, when i plug to P2 it's out put at 2A only not fast charge.
But when i plug original charger from P2 to another phone fsst charge status is become.
???

How many times will you open new topic for the same problem ?

Is it possible to enable 15W USB-C fast charging? (5V/3A)

I ask this since it seems more feasible than enabling something like Quick Charge 3/2.X since this method is open and not proprietary.
It also seems feasible since the OnePlus 3 can clearly handle up to 4A of current at 5V (dash charge) so in terms of hardware it should be able to handle 3A at 5V similarly to the Nexus 5X/6P via the standard USB-C spec.
It doesn't even seem to be able to handle 2.4A via a USB-A to USB-C cable, or even via a USB-C charger using a USB-C cable.
Is there some hardware or software limitation I'm perhaps missing? If it's a USB-C device it should be able to charge via the USB-C standard
To my knowledge one plus promised dash source by the end of July. Also to my knowledge is something must be enabled and PCB hardware must enable fast charging. Galaxy s7 doesn't have qc3.0 despite having the correct hardware.

i do understand something needs to be enabled for QC2/3.X but why for USB-C?
Short answer ... no one knows and they're talking out of their ass ...
Long answer - Even if its a hardware/software enabled type feature - most do not know how to program it well enough to incorporate it. So everyone has to rely on source code with it already programmed to include it with any rom. Some guys can program it but dont have the resources and/or phone to do so. The average programmer reading your comments doesnt know specifics which is why you get a lot of "to my knowledge" "as far as I know" "in theory" type statements

Quickcharge is closed and proprietary, it's just the licensing is cheap. It only work on phone that have recent qualcomm SoC. Yes our OP3 have a SD820 but the manufacturer also have to implement it in the phone, with software but also hardware.
It's a shame that Oneplus didn't use Quickcharge because with the price of one Dash Charger or VOOC charger you can buy a 6 port quickcharge 3.0 charger... And quickcharge can use standard cable (if you use another usb C cable than the one provided, the red and blue one, dash charge don't work even with the dash charger)
So I'll tell you one reason why the Oneplus 3 won't support quickcharge even with some hack : charging a lithium battery at a high voltage make it go BOOM!
Quickcharge use 9, 12 or even 20V to make charge faster (and it's an advantage with low quality usb cable). So the phone have to be able to convert 9 or 12V down to 4.2V and it's a hardware matter.
Now for the 5V/3A of the USB-C spec, it's Oneplus that limit it (and it's safer that way). I tested many charger with a voltmeter. I used some charger from 1.8A to 2.4A and it only draw 1.5A. I used a genuine apple charger at 1A (the A1400) and it only draw 0.5A, the same when it's hooked on a computer. With the dash charger and the dash cable, it go up to 3.5A. It's not 4A but it charge pretty fast. With the same charger but with a normal USB-C cable (2.0 and 3.1 i tried) it draw 1.5A.
So the dash cable use some extra pin to make the phone identifying the dash charger and the dash cable, when one is missing, it charges at 1.5A or even 0.5A.
Why Oneplus don't use the full 3A of the USB-C spec? Dash charge/VOOC I guess.

If it's "unsafe" then why would Google use in the Nexus line? If anything, all of the quick charge out of spec systems (like dash charge or quick charge) are "unsafe"

you can have BOTH. why REMOVE USB-C 15W charging?
charging slower is safer than charging at high voltage or intensity, I didn't imply anything else.
If the charger provided can do 5V 3A like the one provided with the Nexus 6P can actually charge at 3A a Oneplus 3, how can you sell a dash charger with a dash cable that do 3.5A (and the VOOC charger that is even more expensive and need a micro usb to USB-C adapter)

Easily? Dash charge is far more quick not to mention heat efficient
Also, slower charging is not safer by default -it's less hot charging that is safer more so,
Dash charge is heat efficient? Yes it will be warmer on a cold day. Like any battery charging slower is better for the battery life.
I don't understand your last sentence, sorry
If you are talking about the efficiency between the power on input and output from the charger, I think that the power is not high enough to really make a difference with a standard charger.
I am still a big fan of Qualcomm quick charge because I could use a 3 meter (10ft maybe) usb cable not even made of thick gauge.

I think what he is getting at is during quick charge the higher voltage results in more heat in the phone, with dash charge the heat is contained in the charger. Thus phone stays cool during charge which is safer for the phone.

Fast Charge

Hi guys, the Zenfone 3 deluxe supports qualcom quick charge 3.0 however it seems to be locked to the oem charger. Any other licenced qc 3.0 charger does not quick charge the phone. How hard would it be to get around this? Mainly for qc 3.0 powerbanks.

This is not true. I am using this one - https://www.amazon.de/gp/product/B01EH11AS8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
and the quick charge 3.0 works fine. I am still using the original type-c cable that came with the phone though.
Note: Make sure that you have plugged in the USB end of the charger correctly, push it all the way in. If it's only pushed in partially, then you may not be getting the full power for Quick Charge. You can verify this by using a tool like AIDA64 from the playstore and checking the "Charge Rate" under battery.
This is where I was told it's not supported.

Update: Sorry guys, I realized that the OEM charger is indeed much faster at charging. Read posts below.
postimg.org/image/6wis1rux1/ - using licenced qc3.0 charger
postimg.org/image/ndr13s0pv/ - using oem charger.
Further test screen off
15min charge with licenced qc3.0 gives 13%
15min charge with oem charger gives 27%
Same test with screen on (playing video)
15mins with either charger yields about 15%, no noticible difference. Seems like the oem charger throttles when screen is on.
All tests are run when the battery is below 20%.
Same oem cable used for all tests.
Using the oem charger to fully charge my phone does it nearly twice as fast as the qc3.0 charger.
Don't know how your able to achieve the same speed regardless of charger
Hi guys, I've been experiencing the same problem with original charger, that's very big and it's seems that didn't have quick charge. I've a samsung charger and with samsung charger it wroks fine. I'll try to well plug thw original , but, it's thinner samssung's one.

Interesting ... I stand corrected now regarding the "Fast Charging" on the lock screen.
I never used the original charger because I bought mine directly from Taiwan which has an US plug which I cannot use here in Germany directly without an extension.
I tried the OEM charger now with an adapter and yes you are right, the Charge Rate with the OEM charger is 2 times faster than with other chargrers.
OEM charger - 2900ma charge rate
Other charger - 1300ma charge rate
---------- Post added at 11:29 AM ---------- Previous post was at 11:02 AM ----------
Actually now I'm confused. When I plugged in the OEM charger, it said "Fast Charging" for a short while and then it says "Charging". The Charge rate also came down from 3000ma to 1300ma and down to 800ma when the battery is at 90%.
I will do some proper tests with the different chargers and post back.
Confirmed: OEM charger is much faster than other QC 3.0 chargers
When the phone reaches 70-80%, the charging rate will slow down and just trickle charge. This is normal as it can be dangerous to keep charging at Fast speeds when the battery is close to full capacity. So if your phone has 80% and you put it on charge, it will not Fast charge regardless of the charger you use.

Thanks for the information
I can also confirm fast charging doesn't work with my QC 2.0 charger. Interesting thing to note is it outputs 5V - 2A and 9V -2A. My guess is this charger from Asus that fast charges the Zenfone 2 would work on our phones because it has the same outputs if you read the description. It's worth a shot and you could always return it to Amazon if it doesn't work.

It would be nice to remove the red light when the phone is charging. Maybe it's something that can only be removed after rooting?

Unfortunately, even though the charger referenced above has the same outputs it doesn't fast charge. Seems you can only fast charge with the included charger. At least we can use our own charging cable. If anyone gets another charger to fast charge the device let us know. It doesn't appear Asus sells the included charger on it's webpage yet.
Not allowing the standard quickcharge charger to work forces people to once again purchase / replace current QC chargers.
One tick to the CONs side of the evaluation.

At this moment, I don't really think it's a CON side...
The quality of all those QC2.x/3.x charger are not even today (may get better in future, however I really doubt those cheap, knock-off charger from China). Some are good, some are outright bad. QC is quite sensitive with the voltage/current delivered by the charger (it's by design of QC, I believe) and not optimum voltage/current will shorten the battery life at best, create danger at worst scenario.
LiPo battery is really not designed to be charged in high speed. The associated temperature issues needs to be check very carefully and charge current needs to be controlled strictly to avoid dangerous thermal runaway. It cannot only be done by phone itself and need co-work from adaptor (switching voltage, for instance.) Thus an adaptor which have good communication with phone is a safety requirement as far as QC is concerned.
Same with me. I bought a wall charger aukey PA-16 and a car charger Aukey CC-T8. Using the ampere APP, The original zenfone charger gets 2800 mAh. And the aukey chargers up to 1300 mAh.
K6 charger also does not enable Quick Charge function on 570KL
Input type: 100-240V 50-60Hz 0.5A - Quick charge 3.0 output: 3.6V-6.5V-3A/6.5V-9V-2A/9V-12V-1.5A - Power: 18W
I am wondering if someone achieved any solution to remove OEM charger lock to use fast charge with third party Qualcomm Certified Chargers/Power Banks?
Sorry to resume this thread but i lost my oem charger and id like to get one that works with the zenfone 3 deluxe and quickcharge. Can anyone post a link where i can buy it or maybe the model number of the charger? The EU version would be nice.
Thanks
Any solution to the original question?

ASUS locked the fast charge function to the OEM QC 2.0 charger that comes with the phone (it will NOT work even with other ASUS QC 2.0 - or 3.0 - chargers, only with the specific type/"model" that came with the phone). Therefore we don't get QC3.0 - as advertised - at all. The QC3.0 compatibility with 3rd party chargers, powerbanks and car chargers was disabled with one of the updates, I think it was the Android 7.0 Update (that replaced Android 6.0) that removed QC3 compatibility. So... any ideas how to re-enable the QC 3.0 functionality?
Quick charge was disabled for other chargers from day one. I'm still on marshmallow (Android 6.0) and only the charger that came with the phone works with 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?
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.

18w fast charger vs 30w fast charger?

If I use 30w fast charger instead on the regular 18w that comes worth the phone will my battery be damaged?

I don't know if you'll damage the phone but i know that the faster you charge it the faster is discharges
Wat charge you use ? Give me link ...and what time you get on full charge ?
No, the phone will just draw what is capable of. You can get a 100W PD charger and if the phone supports PD, it will charge at the maximum that i can (which will be way lower than 100W) If is no PD compatible, probably will fall down to other standards that both the phone and the charger are capable of, like QC3 or if they don't, to the good ol' ""5V 2A""
There's no problem if you use higher wattage type C chargers. You're just overspending on something your phone can't fully utilize. Your phone would still just ask what it's programmed for charging and the charger just provides power to satisfy, given that it could.

Wireless Charger Pad Slim EP-P1100 Isn't it fast charge?

Guys, I bought this Wireless Charger Pad Slim EP-P1100T, to use on my Note 10 Plus, the information says it has a fast charge, but when I put my device on it, fast charge information does not appear even though it is enabled on the cell phone, is it really so? Android 10 does not show the message?
I think you should use Quick charge 3.0 charging head not the samsung 25w head with it , anyway even if you use the suitable charger with it Note 10 plus automatically shut off fast wireless charging when using slim pad for more that 20% of fast charging because of heat issues since slim charging pads don't have cooling fans and they heat up very quickly
I have one of these also, the only fast charger that enables fast charge with that wireless charger is my old Note 9 charger, it provides the 18w QC2.0 the wireless charger needs.

I'm using the charger that came with Note 10 + ...
Is that why the phone doesn't charge fast charge with the pad?

Yes, this charger was designed for the previous generation of phones (S9, Note9 ect) which included a compatible charger. Samsung confirms this here: https://www.samsung.com/us/mobile/m...nes/wireless-charger-pad-slim-ep-p1100bbegww/
Samsung doesn't use Quick Charge technology since it's a Qualcomm only feature and Samsung uses its own chipset which isn't Snapdragon.
Instead, it uses Power Delivery which is a standard and better in all aspects.

That's not entirely true, Samsung definitely do sell phones with the Qualcomm Snapdragon SOC and the 15W charging on most of their previous phones (S6, S7, S8 and S9 generations) was QC2.0 or QC2.0 compatible. This is why I am able to fast charge my Exynos Note 9 at full 15W with a QC3.0 charger.
USB Power Delivery is good but it's just another charging protocol, later versions of Qualcomm Quick Charge are also USB-PD compatible.

That's right it is, but there's more.
It's not just an other charging protocol, it's an USB standard, that's means all USB ports will have it by default.
Quick charge is proprietary licensed and will be dead soon because there's no use of paying licence for nothing.
And it's not the same at all. Power Delivery is made for dynamically adjusting current intensity and tension depending of the device you plug in and battery level, for them to take only what it needs.
Quick charge isn't, that's why you need dedicated QC ports on chargers.
It's easy for QC to be "compliant" if it shares one similar spec, but it's useless since all next USB ports will use USB-PD.
And that how it worked before, with fast charging, you only had to take in consideration that the output specs and the chargers is equal or higher to the input specs of the battery to get fast charge, but it's risky for the battery.
It may appear silly, but for efficiency and durability, lithium ion battery should not be charged at the same current and intensity at all levels and that's at least one reason why it's important.

I disagree but there doesn't seem to be any point in telling you that you're wrong.
