Fast charging iphone 12 problem

[TellMeWhatIsThis]

Hi guys, I am using a prolink 65 watt charger. I can fast charge my iPad Pro 10.5 because I heard the beep or chimes twice. However, I couldn’t get the fast charge on my iphone 12 or 11. Didn’t hear the double beep. And charging iphone 11 from 35%-100% takes two hours.

I am using the original USB c to lighting cable.

Anyone facing the same problem?

On iphone all the while no sound.

Within the first 45mins-1hr mark. batt should be around 80%+ to constitute fast charging.

The last 10-15% always takes long to go full. What is ur optimised charging setting, and has it been switched off?

I am using the additionally purchased high powered usb c power brick tgt with their usb c cable too for a few years liao.

My optimised charging is on. I will charge and record the time again when my phone hit 10%.

Many ppl reported hearing the chimes sound once or twice.

first chime is 5V charging. second chime will only happen when below occurs:

1) u using PD charger
2) your batt level is below 80%

if the above is true, then it will charge at 9v which is ur second chime

The above two are true but I don’t hear the second chime. mister battery lite shows 14-15watt on my iPhone XS(14% batt).

Gonna try my iphone 12 later.

Turn off optimised charging and test first lo.

No 2nd chime doesn't mean no fast charging, that 2nd chime is only characteristic of some PD chargers.
