2017 Mercedes E300- Very slow wireless charger!! Any fix?

It tunes on but just keeps the charge it has, maybe 1% every hour!

I have a Samsung s23, the quick wireless charger is all set on my phone!

Cant believe Benz has all this technology but has the worse wireless charger I have ever seen!

Wireless charging is one of the most inefficient way of charging, it heats up so much I call it a phone warmer. Therefore I don't recommend using it. Sorry if that wasn't the answer you were looking for : (

My Audi a7 had a fast changer with no heat!

Mine works fine in my 2017 E400 wagon. Never really checked to see how fast but it's certainly faster than 1% per hour.

Could it be the case?

I took it off and cleaned the cradle!

Something is wrong. Make sure that you phone rests flat on the charging pad.

On my Galaxy S24 there is a setting at Settings/Battery/Charging Settings to enable both fast charging (25 watts) and super fast charging (45 watt via cable). The wireless charging in my '18 E300 is very fast and takes only a few minutes to charge from 30% to 80%. The Galaxy S24 indicates fast charging on its display.

yes I did that and it rest flat with no case!

Your experience is not normal for the MB charger. Time to get it replaced.
As an alternative you can plug in your own charger for the phone.

I see then something isn't functioning properly.

Lots of people with the same problem!

Hmmm, seems so.

What is running on the phone when wireless charging? Do you have AA running along with Google maps or Waze? Those can draw a lot of power and negate the wireless charge performance. Also, how old is your phone and do you follow proper battery care? Do you let it drain to zero or charge it to 100% often? Both are bad for overall battery health. I'm not saying the problem are with your phone but don't rule that out either. Try powering the phone off and charge wireless with the car to see if something changes.

Yes. Seems normal to me. My 2012 Volvo made a similar sound. Can't remember what the tech said it was but he said it was normal

OP mentioned no problems with an audi apparently so assuming app usage is the same, the MB wireless charger might be weaker or not functioning properly.

I read its the fuel pump releasing extra air from it and its normal.
