Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Nextbit Robin can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Charging speed with a Quick Charge 2.0 adapter is as expected: excellent. It is in line with other phones with the same capability.

Will Quick Charging work with my Motorola Turbo charger if I use the Robin cable on it?

I'm not sure, but I've tested it with Aukey (wall) and Anker (car) chargers, both work fine with Quick Charge 2.0 speeds.

I charged with the official charger and a Iselector Qualcomm quick charge and nothing as well. Iselector worked on both the V10 and G4. Not sure why this is not working

Nevermind. Charging fast now. False Alarm lol

I thought the charging speed was great when I wasn't paying attention, but when I did actually pay attention and time it, it took about 1 hour and 40 minutes to fully charge. So, I would check into that. Also, the Robin doesn't seem to be USB-C Power Delivery Compliant to deliver the rapid charging like the Nexus 6p and Nexus 5x does, so getting fast charging from USB-C chargers that take USB-C to USB-C cables is useless, you'll get standard speeds. So please implement USB-C Power Delivery in the successor to the Nextbit Robin, so we can enjoy that fast charging technology as well, in addition to Qualcomm Quick Charge fast charging technology.

I am waiting for my Robin to be delivered. I am really confused about the charger. Does it show anything on the screen when a proper quick charge 2 charger is used. Like, in my Nexus 5X when I use original charger it shows "charging rapidly" but when I use another charger it shows "charging" or "charging slowly" depending on the source.
I'm from Bangladesh and it's hard to find a certified QC 2.0 charger. Is it ok if I buy a charger which is has 5V2A or 9V2A or 12V1.5A written on it?

What version of the os?

With a Qualcomm 3.0 charger and 3.0 cables, I get 2500ma speeds (12.5w). Only when charging from less than 50% though. The charging speed slows down as you approach 100%. The lock screen should say "charging rapidly" if it's working though.

Wireless Fast Charger ???

Is there a wireless fast charger that works with the G6? Every ine I have tried only does standard charging. Even the Samsung works but it won't fast charge. Any options?

I bought this INTS Fast Wireless Charger Silicone Antiskid Design Ultra-Slim 9V Qi Quick Charge Wireless Charging Pad for Samsung Samsung Galaxy S8 S8+ Qi-enabled D https://www.amazon.com/dp/B06W2KH6NK/ref=cm_sw_r_cp_apap_jj4brbTbVoMuL it doesnt show its fast charging but it charges my g6 fast and it you need to take out the case for it to work.

That seems to be the case with all fast chargers. Only Samsung can wireless charge from what I have seen even though they all advertise it

Yeah, mine also is charging pretty fast wirelessly. I have this one

Stupidly lg had a patent and released a video about their wireless fast charger bit out be out for the v30 im sure. https://www.google.com/amp/www.digitaltrends.com/mobile/lg-quick-wireless-charging-pad-news/amp/

no, just the lightning bolt for charging. That's it. It's not "fast" charging wirelessly. But honestly, only about an hour, I can get a charge from about 35-40 %. But, when I plug in the cable the fast charge symbols show up. and it's DEFINITELY quicker.

That's exactly what I have been noticing. I tried both the G6 and S8 on the samesung charger: G6 said it was standard charging. THe S8 says its fast charging bu tells you it will take 2hr to go to full.
Wireless charging is great for overnight charging and that's it if you ask me

The LG G6 does NOT support fast (wireless) charging. So there isn't one it'll work with.
Sent from my LG-H872 using Tapatalk

Wireless fast charging isn't really fast charging. Not the same way it is with wired fast charging at least.
I believe it only charges as fast as a regular charging cable, which is still faster than standard wireless charging.
Try using a regular non fast charging base, see what the charge time is, then try the fast charging wireless charger, if the times are similar, then it's fast charging.

Who needs wireless charging with QC 3.0 unless it's overnight

Can I somehow disable my HTC fast charging?

Is it possible?

I don't think so, no one has done it AFAIK. It would probably require some rom or kernel modifying. Why would you even need to disable it?
You could use a simple two wire usb cable that's incapable of sending data - this way device and the charger can't do a handshake and it should display "slow charge" on the phone.

You looking to limit charging speed and temps (to prolong long term battery life), or something like that?
Quick Charge (QC) is massively useful IMO. Such as getting on a plane, and need to top off quickly at the gate. Benefits outweigh the theoretical consequences. Battery life decline is hyped way more than it should be, in real life usage (looking at you, Apple!). I've had a number of smartphone and tablets which I used for 2-3 years with no noticeable decline in battery life (even using Quick Charge).
If you don't want QC, just use a charger that doesn't support QC. The stock charger that came with the M8 was a standard one (no QC).

Isn't the stock M8 5V 1.5A charger actually quick charge 1.0?(at least the european variant afaik)
Some chargers I've used made the phone display a "slow charge" popup, so the original one seems to be faster. Then again - I've used a 2013 samsung feature phone charger and it was "fast charging" so not 100% sure.

AFAIK, only standard (no QC) chargers were shipped with all M8 versions, at least at original release. I remember from reviews and folks complaining that the phone supported QC2.0, but did not ship with a QC charger. And you had to pay for a QC charger as a separate accessory. Now, there are many versions, and a pretty long time period when these devices were sold from HTC. So it's possible at some point (or for some versions) they did ship a QC compliant charger. But I don't think I remember hearing of that happening (but again, it's possible).
The charger is only compliant with QC if it actually says "Quickcharge" (1.0, 2.0, etc.), "QC" or has the QC lightning bolt/circle logo like they show here: https://www.qualcomm.com/solutions/mobile-computing/features/quick-charge
Far as I've seen, only these "QC compliant" chargers will work with Quick Charge (actually charge the phone faster than the "stock" charger).
Case in point, I bought a QC2.0 car charger, and it charges almost double the rate of the "stock" HTC charger included with the M8.

Not 100% either, but I think the "slow charging" message means less than even the intended "stock" (non-QC) charger. Basically, an inferior or otherwise lower output (amps) charger.
Now, when you say "fast charging" are you sure it was actually "Quick Charging" or that it just didn't say "slow charging"? From what I can recall (don't use the M8 as my daily driver anymore) the phone will just say either "slow charging" or "charging" and there is no on-screen differentiation between "normal" charging and "Quick Charge". The only way of telling if QC is working, is that it charges much faster (battery % rises almost double the rate).
So basically, my understanding is that there are 3 conditions: slow charging, "normal" charging, and Quick Charging. But the on-screen message will only tell you of 2 conditions: either slow or normal/QC - with no differentiation between normal and QC.
Samsung "fast charge" is proprietary, and doesn't comply with Qualcomm Quick Charge. There have been numerous reports of Sammy "fast chargers" not working with Quick Charge. Which makes sense, since my understanding (as mentioned above) is that only QC branded/licensed chargers will work with Quick Charge. Never actually seen a Sammy charger working on this phone with Quick Charge. But again, just because I haven't seen it, doesn't mean it hasn't happened. It would help if the phone manufacturers could stick with standards, instead of insisting on developing proprietary crap, and confusing all of us!

Checked mine, no logo or "quickcharge" text. Also I've found no info anywhere that it's quickcharge capable, so it seems it's a normal charger, just a bit more powerful.

Out of curiosity I've checked what the phone displays when charging using a properly working usb cable and a simple power-only one, both on the stock charger brick.
On stock rom lock screen it shows "charging" on the bottom on both, but with addition of "slow charge" notification on the latter.
RR 5.8.5 shows "charging rapidly" and 1600mA and 9.0V - very likely just a set text as voltage is false and nothing changes. Using power-only cable it's "charging slowly" with 500mA and 9.0V - same thing.
So it is as you said - two types of message for either "much less than normal" and "normal or more"

The old Samsung feature phone charger is 4.75V and 0.55A, yet for some reason M8 decides to put in on par with it's own 5V 1.5A charger and say they're both "normal" when charging, weird.
But I agree with you - all those different technologies confuse and prevent us from having just one power brick to rule them all fully work on many devices - there's Samsung Adaptive Fast Charging, Huawei Supercharge, OnePlus Dash Charge, Motorola TurboPower, Oppo Vooc , MediaTek Pump Express and maybe even more. Good thing that at least any phone can get charged using any brick - faster or slower, anything is good in an emergency.
At least it's not as bad as it was back in time, when every phone manufacturer had a different charging plug - can't forget those Sony Ericsson plastic things that used to break off.

45 Watt Charger Options

In the USA Samsung have a charging kit which includes a 45 watt charger. No sign of something similar in the UK. Anyone spotted the official or compatible charger. Thanks in advance.

Some advice on Note 10+ fast chargers in this article:
https://www.androidheadlines.com/2019/08/samsung-galaxy-note-10-plus-45w-fast-charging.html

I just wonder how important a 45w charger is?
Personally my charge always lasts the day and I set my phone to charge overnight every night. It doesn't matter whether its on a 10w, 25w, or 45w charger - it will still be fully charged by morning.
What does a heavy, hot charge do to the life of the battery?

That's exactly what I've been thinking too. I don't even own a wireless charger, have no need for it. When I need to charge my phone I just charge it with the reg. charger or plug it in, in the car. The existing fast charge technology is fast enough. I added that above post seeing that there is much interest in this subject.
I've heard that the N10+ stock 25W brick takes only about 1 hour+ to go from 25% to full. The 50W charger is just another 'hype', in my opinion, created by the phone manufacturers to show-off that they are on top of the best technology there is. And, of course, to get some extra revenue.

Edit: some reviews say it gets really hot.
This says it uses PPS 2.0, do you guys think it's legit?

Personally, I charge my device at least twice a day, more if I connect to my audio interface as that draws power from the phone. I also have the hotspot permanently turned on which can kill the battery really quickly.
Dont really care what it's doing to the battery as it'll be gone back to Samsung next year through the upgrade program.

Just read the Android Authority article on 45 watt chargers and decided to pick up this one. Once my battery has gone down I'll see how much better it is than the one provided in the box.

Almost every article out there now states you need PPS for the super fast charging to kick in. Looking at the specs of that charger, it's all fixed voltages. Not surprised it didn't charge faster.
I'm wondering how the Aukey PA-Y13 will fare, since it does have continuously variable voltage (PPS) but not 10V 4.5A.

You should be able to use most usb C laptop chargers to get the 45W power output, but it also has to have PPS as far as what I have understood. The original one will work of course and it's always the recommended choice - tough you may ask yourself if you really need it.

I bought one for travelling. When flying I have moments that I really have to charge fast. And as it may not be perfect for the battery I will just use it when flying.

I never heard of so much about longevity before the Note7. The way people talk about it like the battery won't even last a year by using faster charging options. I feel they wouldn't give it the option if it would greatly shorten the life of the battery. Makes me wonder if the Note7 never happened the way it did and this charging option we wouldn't be talking about battery health.

Slow wireless charge on my s20 ultra

So I'm having a problem (I think). Until now, I charged my S20ultra with its very fast charger and with my wireless anker (10W model) connected on my usb pc port. While connected on USB port, I know the charge is very slow (takes like 5+ hours from 0 to 100%) since it uses only 5W but I dont mind since it's wireless.
Today I conncted my anker wirless to a normal charger (its the one coming with samsung A51, supports fast charge). I thought that would speed the wireless charge up (since my anker is 10W but on pc usb port it can only use up to 5W), instead its still slow. Using accubattery sometimes i see the actual charge rate rarely go up to 800mA but almost all the time its about 200-400mA. My phone right now is at 54% battery so its not even at the end of a charge (at the end i know it slows the charge up with all chargers), accubattery shows 13%/hour charge which is very slow. Anyone know why this is happening? Why isnt my wireless anker using its full speed?
PS Android says its using wireless rapid charge, so its not like it doesnt recognize it. I also tried removing the cover but doesnt change at all.

Not sure what output your A51 adapter does, but for full 10W output on the Anker wireless charger it must be plugged into an adapter that does 9V-2A output and QC3 compatible.
You can find the output on the wall charger by reading the very small print on it

Thank you!! Well this might actually be it, the A51 adapter is 5V-2A or 9V-1.67A. I guess this might be the reason then... since you've been so kind and you have exactly the same wireless pad I use, can you please link me your adapter? I was thinking to buy this anker one: https://d2211byn0pk9fi.cloudfront.net/spree/products/57202/product/A2010311_ND06.jpg?1505382537 Has 9V-2A and its QC3 but just to be sure i'd rather go with the one you got since its working. Thanks a lot!

Thank you! One last question... do you think the lack of usb-c port might be a problem? I noticed your adapter uses it but my anker pad has a microusb-usb b cable so I cant use an adapter with usb c but just the old normal usb port... was wondering if that might cause problems. I guess you use a usb c-microusb cable to connect your anker to motorola charger right? Thanks!

Not being usb C on the pad shouldn't be an issue, comes down to how much juice the wall adapter pushes out . And yes I use a USB OTG adapter (usb C male to USB A female) to work with that moto charger. I think you should be fine with that Anker charger you linked and then using the cable that came with the pad.
I only use wireless charging over night so I haven't really tested to see charge rate as I just let it go as I sleep, I'll make an effort to watch it sometime to see what actual rates I'm getting.
Hope that helps .

Just an update... i received the charger today, but even with this one so far it doesnt seem to change much, it charges like 12-14% per hour. If possible I'd really love to hear from you if your experience is different, I know its hard since you just leave it to charge during night, but maybe if sometimes you happen to charge it for an hour or so during day would be interesting to see if you have similiar results or a faster charge... thanks again!

This is what I'm seeing, granted I was already charged to 60% before I took this screenshot. Also I have an S20, so smaller batt than its big brothers ..
No charger (wireless or wired) will ever reach their theoretical charge rates ... I know me using an OTG adapter into my PD charger leaks power almost as much as wireless charging itself . Convenience is why I use it though..
I think for the best/fastest Qi charging, we have to get the Samsung official charging docks/pads.

Thank you man... one question, does it stay at around 1100-1200mA all the time? What I noticed is that my phone sometimes goes up to even 1400-1500mA but it stays like that for a very short time, few minutes, then rolls back to 200-400 most of the time (so very slow). If your phone is always charging at least 1000-1100mA then for sure theres something wrong with me, but i read a lot of other people seem to have problems with s20/s20+/s20ultra wireless charging, even with the samsung original 15W charger. Thanks!

i never see drop below 1000ma, is the low end... again as i charge overnight I'm not sure if it drops past that, but it sounds like you have way slower charging than me..
i still carry my anker pd charger for true fast charging
edit.. is your device snapdragon or exynos? I'm snapdragon

Mine is Exynos, and even the 20+ from this other guy having problems with samsung own 15w wireless is exynos. Would be sad if this was just another problem with exynos, not being able to charge it as fast as with SD. You've been very kind, the last thing you could do is maybe sometimes when you charge it, see if accubattery is really always at 1000mA or more, or actually drops by half if not more for you as well sometimes. I'd be happy to even have a steady 700-800mA charge, problem is that its almost always under 500, but for a very short time i DO see it going up to 1400 so it means the power provided can reach the phone, it just doesnt last, i really wonder why.
If you could check once in a while would be really appreciated. Thanks man!

It's been solid @ this rate till ~60% then drops down to 1000-1200 ... haven't seen any spikes or dips, it's pretty consistent. Don't know what to say, it's a bummer that your device seems to have issues with Qi charging. And doubly sucks if it's an issue w/ Exynos devices. Wish there was another person here who could chime in

Seems everything is in order with you. I also wish more people would jump in sharing experiences, sadly it seems not many of us charge it with wireless. Other day I was searching online and on Reddit I found some s20+ exynos user with the samsung 15w wireless original charger with the same problem, there would be almost no difference between that charger and a 5w one. The chances that its both his charger faulty and my s20 ultra as well are very low (beside my s20 with cable and 25w samsung charger goes to full in about an hour, and if it was a problem with wireless it wouldnt charge at all all the time ), so maybe the problem could actually be exynos but who knows... anyway thanks a lot for your help, lets hope someone else jumps in this thread. I was almost rdy to buy the (very expensive) 15w samsung charger but at this point im not even sure its really faster.

Update: just put on the pad to charge, was at 26%, went to 32% and accubattery showed always 1400-1500mA. Now its stuck below 500 again, temperature 36.4C so not even hot to drop. I really am gettin pissed off at this, how is it possible it charges full power for a short time and then drops.

Another update... Anker just replied to my email sent days ago about my problems with the charger, here it is:
"Recently, our various markets have feedback that this S20 cannot achieve fast charging. The specific reason is that our engineers are still testing. Because we did related tests before it was put on the shelves, there was no problem. But now it is confirmed that there is a problem, so we recommend that you do not buy new products for now."
So apparently there is a known problem, altho im not sure hes talking about s20 in general or about s20 ultra since i wrote i had an s20 ultra in my original email. Also its not clear if its just markets with exynos or those with SD as well. But it does seem that there is a problem that they know about...
