Fast Charging Problem Asus 6z

It seems like a hardware problem. No such reports on Zentalk.

I noticed in your screenshot you have VoLTE.

That is not supposed to be possible according to Asus?

There's a "+" in the icon, so it's fast charging, just not as fast as "++". When fast charging isn't working, there is no "+" in the battery icon**.



In my case, I can only get the two "++" with the Asus original charger as all other chargers I have don't charge fast enough.

If you're having problems, you should do what they told you at the service centre.

(** It takes a few seconds for Quick Charge to enable, so you won't see the icon right away)

Hello friends


Nearly 1 month before, my phone started showing "Charging" when I connected the charger to my phone, instead of "Fast Charging". There was issue of connectivity with my laptop also. My phone was sometimes detected on my laptop, and sometimes not. I tried with another 18W charger, as well as with another 3Ampere Data Cable. But it always showed "Charging" only.


I went to Asus service center, where they also couldn't find what the problem was, and told me to deposit my phone with them. I instead of giving them my phone, went home and did a Factory Reset.


Afterwards the problem was gone, and it always showed "Fast Charging" when I connected my phone with charger.


Now since yesterday, again this issue is there. But this time it's little bit different. After connecting charger, phone shows "Charging" for about 1 minute, then starts showing "Fast Charging", but there is only 1 Plus in the battery icon in the status bar. And this thing does not happen every time. Sometimes, it shows "Charging" only, and not fast charging at all.


I have tried cleaning the Type-C port of phone as well as Data Cable, tried changing the cable used for charging the phone, tried changing the charger, but still no luck. I again did a factory reset, but this time it didn't solve my problem.


When I searched Fast Charging Problem Asus on google.com, it showed that there was similar problem in Asus Zenfone 5Z.


Has anyone facing this problem? Or if anyone knows how to solve this?


I don't want to get my 2 months old phone opened by service center at all.

Not really helpful but I'm having the EXACT same problem. Only in my case it stopped working completely, even after a factory reset.

This started on Android 9 and after the update to Android 10 it was fixed! Until I rebooted my phone and now the same problem occurs. Everything you tried, I tried too and nothing seems to work.

I hope you'll have better luck than me solving this issue, because for there only seems to be one option left and that's to send it to Asus repair centre.

I'm pretty bummed out especially because I have the 30 edition. It was naive of me to think they'd actually put extra care in this version of the ZenFone. I'm utterly disappointed and not looking forward to having this phone opened.

If you're using a 3rd party cable, try using one that came with your phone.
Before upgrading to Android 10, I was using a 3rd party cable and was getting fast charge. After the Android 10 update, however, fast charge stopped working. Once I swapped back to the cable that came with the phone, fast charge started working again.
So if you'reusing a 3rd party cable, trying using the one that came with your phone and see if fast charge starts working again.

Everything depends on the current battery charge percentage.. @ 30% my phone charged at the speed of 3020MA unti 60% then dropped to 2500, then at 80% it was about 1100 MA and once around 90% i saw 650MA.. all readings using Ampere app on playstore..

Even I am facing the same problem with 6z I have the original charger but now it doesn't shows fast charge. And sometimes it takes more than 6 hours to charge the device from 15-20% to 100%. There no + or ++ sign on battery icon. Started happening after the latest update.

I have same Fast Charging issue with Asus 6z mobile. Is there any solution for this problem.

Not because of connector...

Guys, i had the same problem, won't connect to computer and won't fast charge, just one plus slow charge, i also thought it was just because there was dust in my charger or in my phone usb port, i cleaned as i could and tried, same experience, it worsened as time passed, as time passed i couldn't charge my phone anymore, charging cable connector was a little wiggly inside my charging port, so i had to adjust my cable somehow to just get charging, i also couldn't get an exact reason for the problem, so i went on with the burden, one day my phone just shut down when it was on 10 percentage battery, i was very afraid to take it to service center as my brother had bad experiences from various authorised and local service center, but one day my phone fell from hand and just won't turn on, it vibrates and it shows the off mode charging symbol for one second and goes, just nothing else, so i was confused with what was the problem whether it was with the sub board(charging port), battery or mother board. Anyways i had to take it to a service center, so atlast i took it service center and they had to send it to somewhere else to diagnose it, after two weeks i got it, they told me that my battery was short circuit(i don't know what that is) and is in bad condition, and the reason i couldn't charge was because of charging board or sub board problem, not because of wiggly port as i thought and battery was 1200 priced and sub board 350 something like that and 400 service charge, total was around 2000, and till now no problem, and they did a clean job as it seems it was never opened and the main thing, they gave me the replaced parts too and that was a surprise as i was very suspicious with these repair centre, i don't know about all asus service centers but the service in Kottayam service center in kerala was good from my experience.
