Samsung Galaxy S7 no Fast Charge after firmware update

Hello,

 

My Samsung Galaxy S7 is in impeccable condition for a smartphone which is getting close to 4 years old.

It still did everything I expect it to do up untill shortly...

 

After the last firmware update at the beginning of december, it suddenly stopped fast charging.

As an avid mobile gamer, the fast charging is pretty much a necessity for me.

 

I have done everything thinkable to try and cure the problem, I have switched cables and chargers, making sure they were all Quick Charge compatible, both aftermarket and genuine. I have checked unchecked and checked the fast charge slider multiple times. I have rebooted the phone into safe mode, wiped the cache and even went through the trouble of doing a backup and factory reset, to no avail...

 

In the Samsung Members app, which I had never used before, I can see the status of the battery is being reported as 'weak', to no surprise for being almost 4 years old, but it did fast charge untill before the latest update.

 

Even if the status of the battery is decided as being weak and it kills the fast charge because of it, I'd rather have it being able to fast charge untill it completely gives up!

 

Please Samsung, fix this issue.

So the notification area should say "Fast charging" (or something similar) instead of just "Cable charging"?

Yes, which it no longer does.

 

It now takes over 6 hours for a full charge and I can't use the phone during charging it or, depending on the activity, it will still drain the battery faster than it can charge.

 

Turning off the phone reduces charge time slightly.

I'm on build R16NW.G930TUVSACSI1 on my Galaxy S7 and fast charging works on 1 of my Samsung chargers:

Mine is now on G930FXXS7ESK7.

I am trying to revert it back to G930FXXS6ESGD, but it wont even connect to a computer over USB anymore, no matter what I do, it just uses the data cable as a charge cable...

Normal cable charging isn't much slower than fast charging:

Wipe the cache partition. If that doesn't help, do a factory reset.

Sorry, I missed that. Ok, you already did that.

It seems the device is broken.

Re: Samsung Galaxy S7 no Fast Charge after firmware update

I'm having the same exact problem, and it didn't dawn on me until I read your post that my fast charging stopped working once I did the firmware update.

My husband has the same exact phone (we got them at the same exact time) and he's been putting off the update and his fast charging still works. Now I'm regretting updating my phone. Because my phone is constantly on life support (connected to the wall charger or my power bank). I truly hope this is something Samsung can resolve with a patch.
