What is your S8 charging rate? (from 0% to 70%)
Mine is:
Fast charge adapter, fast charge on: 2.4A
Fast charge adapter, fast charge off: 1.6A
1A sony adapter: about 900mAh
Computer: About 500mAh
I tought "normal charge" with the fast adapter would use a lower rate. What do you think? I choose longevity (low current and low temp during charge, not going over 4.1v) over charge time, so i charge the phone to a max of 80% and at the lowest rate possible. I usually plug it in when i get home from work, and about bedtime is charged.
(My 3 year old Z1c still got 1 day battery until i broke the screen)
Fast charge adapter, fast charge on: 2.4A
Fast charge adapter, fast charge off: 1.6A

I think you mixed up your measurements.
Fast charge is 9V @ 1.67A (15W)
Standard charge is 5V @ 2A (10W)

Can we use this USB to fast charge our Note ?

Thanks
It's a charger that will charge fast simply because of the high amperage. I believe, and trust me I could be wrong, the fast charging capability has to do with the plug's output. Your typical outlet plug is 5v, anywhere from 500mah - 2.x amp. The higher the amps, the faster the charge. If you look at the fast charging plug, you'll notice it's 5v 2.1amp OR 9 volt 1.67 amp. I believe the ability to fast charger comes from the higher voltage capability. So while the 2.4amp charge rate is good and will charge fast, it's not the fast charging like using the higher voltage Samsung plug.
Recently bought a Choe 15W fast charger and when i use it, the battery recharges at 2.5A which is significantly faster compared to my samsung charger at 1.5A. I also read that quick charge 2.0 should not let the current to increase above 2A. Is this normal? The temperature is also higher at 44 degrees celsius compared to 41. I thought E8 should have quick charge 2.0 implemented based on gsmarena.
quick charge 2 works at 9V/1.67A
its not about the amps only
it means your charger is not quick charge 2.0
dont use it
Next week getting a new Note 4 - and zerolemon 10,000mah battery!
I need to deep cycle battery 6-8 times to get phone to display the current vbbatt % correctly. The manufacturer for zerolemon says turn off fast charge and charge 12hrs each time.
That being said, with fast charge off, can I use a 5v 3.5 amp charger I see on amazon and possibly charge the phone faster than 12 hrs like normal is using a 2.1 amp charger?
Anyone tried this with let's say even the stock battery does the battery actually charge faster due to the increased amps or would it be a waste and still charges at the slower 2.1 amps?
I never deep cycled the battery and the longest discharge I got was 1 week with 16 hours on screen time...you just need to make sure you use an updated kernel with the zL fix.
The amperage rating is the max the charger can put out. The Note will draw the same amperage on either charger because they are both 5V.

But will the phone charge faster on 3.5 amps at 5v vs the 1.5 amp or 2.1 amp the stock charger puts out? I am getting ZeroLemon and need to deep cycle the battery a few times and am trying to have it fully charged in less than the standard 12 hrs - was hoping a charger with more amps would cut down on the 12 hrs lol

i just used the stock fast charger on my zerolemmon with fast charge on and i never let it go the full 1 hours. Ive had insane battery life with it so i dont think it matters

Your Note 4 will draw a maximum of 1.9A on a 5V standard charger and a maximum of 1.66A on a 9V Quickcharger. If you multiply these values, you will get your "charging speed" in Watts: The maximum is 9.5W on normal charger and 15W on a quick charger.
Using a higher rated normal charger (eg 5V/3A) will NOT INCREASE charging speed. The Note 4 will never draw more than 1.9A on 5V.
Using a lower rated normal charger (eg 5V/1A) WILL DECREASE the charging speed. The Note 4 will notice that it cannot get 1.9A from the charger and drop the current. Bad and/or long cables can also influence the charging speed negatively.
Also noteworthy: Quick charging will only work when screen is off. As soon as you turn your screen on, the charging speed when connected to a quick charger will drop from 15W to an extremely slow 5W. The only fix for this horrible Samsung joke is a custom ROM like CyanogenMod.
You can charge your Zerolemon battery nicely with the original Quickcharger that came with the phone. That will do 15W and is as fast as you can possibly charge.

Wow. Good info. Thx. Now a ton with a hack to draw more amps lol. Hmmmm lolol
If it goes in this adapter...it should still fast charge? Will it charge even faster?
In most cases it should charge at the same rate as the stock cable and charger (fast charge 2.0). It will not charge faster than the fast charge 2.0 as that is a limitation of the phone, wall charger and cable.
I've had my 7 Pro 8/256 for a week now and was really hoping to see USB-PD 5V3A charging. In fact, I ordered a USB-PD USB-C power bank specifically for this.
I've also tried my Aukey PA-Y10 46W Wall Charger as well. USB-PD (PDO) 5V 3A | 9V 3A | 12V 3A | 15V 3A | 20V 2.3A.
USB-C to C Cables, U Green 3ft and Aukey 3ft.
When I connect the power, it doesn't indicate "charging rapidly" as it does on Pixel 2/3. Tested using Ampere. 1.7-1.9A even when the battery is only at 20-40% Far cry from 3A max.
When connected to the Dash Charger from my OP5 with OP5 cable, I get the standard 5V4A (3.3A in Ampere) of Dash with a Charging Rapidly logo and a blue lightning bolt.
Were we lied to? The article says it is supported but there is nothing indicated during my real world testing to show it actually is any faster than using a 5V2A charger. I livechatted with OP Support yesterday and they did confirm that OP7 Pro supports 5V3A USB-PD spec but the rep didn't understand what I was asking when there was no notification for rapid charging.

yeah on my PD charger it takes 1 hour 50 to charge from 20 to 100
If you want to see the actual rate of charging, I recommend using an app called 3C Battery Monitor. I use it to keep track of my phone's rate of battery drain when using certain apps or how fast something is actually charging. In order to save battery, I only have it logging the battery usage every 10 minutes but you can set the rate to be faster.
I'm my first picture below, I was purposely draining the battery down to 1% to test out the speed of the warp charger, but it was only sampling every 10 minutes.
My second picture is set to every minute.
Give it a try to test out the PD charging as you will have actual mA/hour figures to compare.
Thanks. Confirmed today that it does do 5V3A but doesn't show as "charging rapidly" using 3C Battery Monitor.
It is about 2.9-3.0A from about 25% until 70%. From 0-25% is about 1.5-1.9A and from 70% onwards it slowly decreased until it reaches 100%.
In total from 17% to 100% took 1h 47 mins. Not exactly fast but acceptable.
With the Warp Charger, it's 0 to 100% in about 1 hour flat. With a Dash Charger, it would be about 1 hour 30.
iPhone XS Max charges 0-100% in 2 hours 20 minutes with a 2.4A adapter
