hi yesterday i just bought zenfone 2 4gb 32gb rom 2.3ghz..
I tried to charge from 20% to 100% its just took 30 minute
when i measured the charge rate using app called Ampere, it showing that the charge rate is BURST and the charge speed is at 2500mA
wow i was extremely happy knowing my phone charge very fast!
but when after i update it just now to the latest version
it took so long to charge the phone
and when i measured with Ampere software it only charging at 1500mA!
wow the charge speed is almost HALFED! are you kidding me???
i wish i didnt update to the latest firmware!
Did you charge from 20% again?
20% to 100% in 30 minutes?
In past firmware there known issue the battery not charged correctly (ex : only 1500mAh charged showing 100% instead 50%)
normally from 0 - 100% arround 1 hour and 40 minutes
yes is slower than usual. tested on app call (battery charging source and current) the data is really slower than last firmware. normal charging rates should be 70k-85k if with asus original charger it can climb to 150k ma. now is unstable sometime drop to 8k 9k ma.
Hi guys, I just want to know how much ampere you are getting with the turbo charger. I'm getting 2400mA but charging speed is not that fast. 27% in 25min.
I get 3000~4000mA in the 0-50% range and 2000~3000mAh in the 50-80% range with the TurboCharger 2 (25w)
0% to 100% is done in about 90min
I also get 4A in the low percentages with the 25w charger. 3c shows this if I choose Moto G mA calculator

So the issue is I bought quick charge 3.0 adapter from xiaomi site but it isn't making much difference because stock thermal values are too limiting
It charges 2800 ma while temp is >37 c
2300-2400 at > 39c
After that at 1900
Is there any way to start throttling from 44-45 c
im shocked 2800mA charginig speed in RN7 as it is capable of 18W fast charging only
but well from my experience with different phones is that as the phone going to full charge especially after 85 % i experienced mobile heatup and the charging current drops, but i think your issue may arise during low charge mode as well
first of all charge your screen while keeping display off and after every 15 minutes you can check for the average charging current and temperature for that session via Accubattery easily
by the way which app are you using for charging current
app is not accurate for checking, use USB voltmeter direct to charger to check charging amps,
in a hot country with high temperatures >30C.....then quick charge will throttle faster as battery heats.
mi 2a charger (redmi note 7pro)
even regular 2a charger (with redmi n7pro) thermal throttle.
i put my phone in charging for an hour ago and i checked suddenly and it has charged only 20% (21% to 42%) and after changing charger the charging speed was back on and also the mi charger was hot would be aroung 30 to 35 celcius.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

with 27W Charger the phone charges from 0 to 55 percent in about 30 mins and 0-100 percent in about 1Hr 15-20mins.
charging speed depend on battery temperature. fastest charging if temp below 35 degree C, around 3500-3700 mA
The charging speed is damn fast.
Please Notice Me
Hello sir, are you using a flashed global rom?
Guys what about 27 watt sonic charger? Is it worth to buy?
charging rate is very slow when i use the phone while charging....its around 1200mah

Are you serious? My 18watt Charger that comes with the box takes 30mins to reach 50% and takes 1hr 25mins for full charge. Then why 27watt??

in my stock charger it charges 44% in 30mins and 1hr 30mins to full charge. Difference is only about 20% while it should be 50% more faster as 27W is 50% more power of 18W.

You are correct. Difference is just around 20% which is not acceptable.
i've decided not to waste money to buy the 27w charger after watching this..
I have two power delivery charger both capable to charge up to 60w. When I connect phone to both charges doesn't matter which one and which cable I use currently it always display fast charging text and icon. Why it doesn't go on turbo charging? If I know the phone support qc 4.0 and PD and it should turbo charge on my chargers, right? Anyway I noticed 3300-3600 mAh however it doesn't really look charge as fast as in reviews.
Some people reported 4A but according to qc 4.0 specification it's rather about 3A at 9A. What's the real charging voltage for our Xeromi?

It seems Xiaomi uses a proprietary protocol for it's 27W Turbo charge. For now I've not seen any other charger capable of charging it on 27W other than the Xiaomi one.
Chinese people are used to lying. Phone doesn't support qc 4.0 and doesn't weight 190 g. It weight over 200 g (200.5g)
The phone charges at 300-500ma when using pubg even when using a 18w qc3 charger which normally charges at 2800ma. Anyone else facing this bug?

Nope i didn't seen it but mine working great i have usb tester so i can check everything about charging i didn't seen charging at 0.5A
Your saying it charges at 2800ma but this is working actually at charges at 9V & 2A so 18W charging but those ampere & accu battery are showing differently. First i thought they are genuine after i bought USB tester I learned a lesson they are wrong

I tried a Belkin 27W QC 4.0 charger(attached), Macbook Air 30W original Charger and one more 45W Type-C charger.
But non of them shows Turbo Charging. Not even the Quick Charging message comes up when using the original 18W charger.
Saw this charger on AliExpress with a seller who had feedback saying it gives Turbo charging.

Try changing the USB cable.

Do you have pubg installed & would it be possible for you to check charging current while game is running in foreground please?
Also btw my charger also has a 5v&3A mode so that's why it was showing ~2.8A

It's not a bug i guess... Its a OS thing .. some custom rom uses the force fast charge option... Then the phone will charge fast even we use the phone or play games.. but in stock roms they disabled the force fast charge thing... So when in idle, phone charges around 3000mah but when using the phone it comes down to around 1000mah or even lower while playing games
So I've been testing charging speed with a quick charge brick(qc 3.0) and a 3amp cable for a while now and i can never reach to 18W (i know its hypothetical but i can't cross even 10W). I'm on latest xiaomi.eu 11.0.7 stable. These are the results I got from ampere - 4V 1.2 amps. I've tried changing the charger but results were pretty similar. I can only get upto 7-8 watts and idea why ? (I've started from 0% battery, 10%,20%,30%). My device doesn't get heated so i don't think it's throttling issue.
