Fast charging - Honor 8 Questions & Answers

What could be the reasons for the phone to not fast charge? I have the bundled charger 5v/2a and also the quick charger purchased from honor website 9v/2a but both are bogging down the charging speed. Ampere app results are also in the post. Anybody who could help? Just for the fact I have an unlocked boot loader with twrp and Magisk and I have alreAdy factory reset it couple of times.

Fast charging start at 0% to 50% battery. And it takes time to ramp up and its not that constant. Better way to check if it's working is to see the charging time from empty.
Also from your notification bar I can see it's not fast charging. Fast charge has 2 thunder icon instead of 1. Maybe it's your cable. I have magisk and twrp my self I can still fast charge from my powerbank

If you just unlocked bootloader and install TWP + magisk, I would say you would still have Fast Charge.
You sure you didn't flash a new kernel?

Yeah i tried both normal and fast charger. Still the same i try to keep it charged all the time because when In need it will take forever to charge i even changed the cable.

Yep pretty sure didn't flash a kernel also is there any kernel even available for honor 8 i didn't find any in the Roms and kernel forums

Quick charge not working.

Hi. Posted this in a couple other places already. Got my XZ yesterday and it doesn't come with a quick charger. Fine, I bought some. None of them are working though.
Tried Anker and Aukey, and also the charger from my wife's HTC 10. Any ideas why this isn't working?
Everything I've read (the specs on the official site) say that this phone supports Quick Charge. I've tested the HTC 10 in all 3 chargers and it quick charges so I know it's not them.
Tried it with Battery Care off and nothing. When Battery Care is on all I get is messages saying "Battery Care has crashed" or something. Pretty annoying, considering I just dropped about £50 on new chargers!

Sony enable Quick Charge only when battery is under 60% for safety reason.

Battery was at 15% dude.
When it's quick charging, does it give any indication? I know the HTC 10 says "charging rapidly".

There is no indication.
You can check with Ampere.
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
This app doesn't show exact charging current, but if it shows over 2,000 mAh (wait about 30 sec) quick charge is working.
Please note there are heat throttling, so quick charge is disabled when device is really hot.
I bought Aukey QC 3.0 and when the phone is over 85%, I get 680ma; below that I get higher rates over 1000ma.
UPDATE: I put my phone in charge at 50% and I got over 2000ma but when it reached 80%, it changed to 600ma. So it supports quick charging but when it reaches to almost full, it activate battery optimization for the safety of the battery.
confirming above, I also came from a HTC10 and was expecting to see a "charging rapidly" message. My XZ also doesnt display this.
When using GSAM, I can see the rate of change of charge, when connected to a QC2.0 or a QC 3.0 charger and at low battery capacity, I can see rate of change of up to 60% per hour, this is in line with my other QC phones. It does appear that Sony throttles charge speeds more than HTC does above 80%, but I can understand that, and it doesnt bother me too much.
Yeah, I've had some time to look at Ampere and would conclude the same.
My XZ on the Anker charger is peaking about 2190ma when charging at a low percent, whereas my Z2 on the old standard charger peaks around 730ma - this is after 5 minutes for both.
Was just a little freaked that it didn't indicate that it was "charging rapidly". Guessing the throttling will also help battery life, although it was a bit of a sore one seeing the wife's HTC 10 peak around 2900ma.
Anyone know if the Galaxy s7 chargers will output 3.0 with the international models??
Did you buy a used phone? My XZ came with an OEM SONY QC 3.0 rated charger. Using Gsam battery monitor pro I get readings up to 2200+ mAh charge rates between 30 and 60% battery. That is generally considered to be the safest range to fast charge lithium ion batteries (fast charge generally being a charge rate higher than .5C, which for this phone is 1450mAh). I don't get any indication it is fast charging, it just does it. QC 3.0 applies a varying voltage and amperage throughout the charge, offering more gradual and "healthy" charge curves as opposed to conventional or QC 2.0 charging. Basically your QC 3.0 charger charges the battery as fast as is possible while not sacrificing battery life (say due to excess heat or overcharging).
Hi, I have recently bought a new XZ & bought the original Sony charger UCH12W at same time. The hour of charged is need approx. 2 hours from the battery percentage 30% to 100%. Is that any one face this ? Or maybe is my charger or either my phone problem.
Try this
Use the the detect usb in the notification keys before connecting the charger,, this will solve the fast recharging issues,, even if phone will recognice charging after few seconds,, charging will be fast and normal

this solves the problem, its sad that you need to do this first and its not automatically fast charging .
Still buggy
Its the only method that i find it working,,, but still there is a chance that phone still wont charge fast so keep an eye on the charging process,, and its temporary solution till next update for soctware as i hope its a bug in android 7

Charging very very slowly

Hello,
I have had this tabled for a while and it was always charging extremely slowly but I never took it out of the house so it wasn't a bid deal for me. However I have given it to my mother and she uses it in other ways. Anyways, the note 10.1 is the slowest charging device I have ever seen. It takes probably 48h-72h to charge it completely. I am using the original cable and power brick, I have tried ALL the outlets in my house, I have tried using the computer, I have tried using another cable (probably like 5 different ones) and other bricks (from iPads, my note 5, etc) and nothing is working. I have seen other posts regarding slow charging but none of them solve my problem.
Thank you
Thats is not normal .
I would factory reset and flash a stock rom .
Swap battery or take to a service centre .

"probably"?
You can't troubleshoot perceptions and guesses. How long does it actually take--repeatably--to charge from what percentage to what percentage? (i.e. "Went to bed, battery was at 40%, charged overnight for 7 hours and battery was at 60%.")
There are apps to check charging current (Ampere being one of them).
The fastest charge you can get is with the OEM charger in an outlet, not a PC.
Understand that this is a 7,000mAh battery without any quick charging applied to it.
Additionally, if you are using the device whilst charging it, you aren't really charging it since the drain is about the same as the charge; you'll effectively neither charge nor discharge.
Finally, check for battery-draining apps; you might not have a charging problem but an app-drain problem.

The time varies, but it is between 2 and 3 days to charge from 0, never less.
I do use the OEM charger and cable and an outlet.
I do understand that but 2 days seems a bit of a stretch, don't you think?
I am definitely not using it while charging, because it's impossible. It just doesn't charge fast enough to be able to use it. It drains quicker than it charges.
I highly doubt that, I only have YouTube and Chrome installed on it.
Above 6 hours with stock rom and charger is abnormal .
Usual replies .
One cable
Two charger
Three battery or connections .
Four USB port
Five motherboard .

Yeah, 2 days isn't right. It also shouldn't be discharging faster than charging, especially with the OEM charger.
I leave mine plugged into my PC (only 500mA max current) with the screen on (about medium brightness, mostly black screen, which is most power-friendly for OLED) using LectureNotes all day and it will neither charge nor discharge (technically, it's charging at the same rate it is discharging); the percentage doesn't move.
What does Ampere report?
Do you have another charger you could try? any 5V and at least 2A would work.
Also, ensure your cable isn't intermittently open (a break in the cable, temporarily disconnecting the charger).
If the cable and charger are good, then the battery would be the next likely culprit, followed by the charging circuit.
Finally, ensure heat isn't an issue (is it in a case? remove it).
Mine was messed up but I concluded it was the port and cable. I got a new cable and then replaced the charging port and viola. Charge time went from 8 hours back to the usual 3-4

Fast charging

Earlier today i noticed that my p2 is not showing fast charging or double volts while charging.. But my phone charged in the same amount of time as it does in fast charging... What should i do?

Are you using a custom rom? On RR mine is fast charging but it doesn't say so. I checked with a usb power meter, it was at roughly 12V 2A.

No its stock rom and no root.. 7.0 nougat latest update
When battery temperature is above some level fast charging is disabled, don't use your phone while charging, check wakelocks, cpu usage and use original charger

Slow Charging!

My 1.5 year olf Q6 is charging very slowly. The battery backup is still 1 day. But the charging rate is very slowly. It shows 3hrs+ for a full charge! What can I do?

get a minimum 2 Amps charger, this phone supports quickcharging (at least thats what i see, and what others said). the stock cable is fine but you might have to try another cable if your charger is already a quickcharge compatible. i can charge from 0 to full in about an hour with 2 amps, you might get better result with a better charger brick but i can't confirm.
I have a V30+ charging brick. That's QC 3.0 Will it work? EDIT: just tried it. It doesn't work. My phone has never shown Fast charging. It just shows charging. The stock brick is 5V1.2amps.
Which brick do you have?

i forgot to tell you it won't show anything that tells you its on quickcharging, the only thing that shows is the faster charge estimation, please try again and observe. my charger brick is a samsung adaptive fast charging with 2amps maximum rating, your charger should be better than mine. borrow another fast charge compatible brick if necessary, and also cable quality matters. else, welp might be hardware issues...
Tried a fresh cable and the stock charger. The old original cable was the culprit for the slow charging time. Charging time has come back to original fast levels. But it's the same with the V30+ charging brick. Don't have another phone that's QC. But will try if I get an opportunity
I'm using Battery saver in Maximum mode (with VIbration enabled) + Comfort View (highest level) with Grayscale. With moderate usage, it takes two days to drain the battery after fully. Though I recharge it at end of every day for an hour for the battery durability. I've also replaced Home with 'ap15 launcher which for me has proved lightest and most practical one.
My lg q6 canadian variant came with fast charging. It's region dependent. Though i don't know if you had fast charge on your variant
Same as my DSK unit. Charging slowly for about 5-6 hour with original wall charger

Fast charging not working.

Pretty much as the title says. My device says its fast charging but it takes hours to increase only a few percent. Its charging faster through my battery bank with 10.5W charging then the super fast charging
Do you have selected fast charging in battery settings?
if yes and not fast charging, try to restore factory settings.
for last, its the charging port problem, i have the same at mine 3 months ago.
in warranty i changed de charging port and a new battery.
