Wireless charging issue

[Eklo]

Hi, I have a galaxy s6 and recently every night when I put my phone on the charger it stops charging at aroung 78 ~ 88%.

I tried the following things, but they didn't work;

Removing cache

Using *#0228#

Any idea what I should do?

probably the battery needs changing

Given what you've said and that the S6 is quite an old device, I suspect the battery is kaput and needs replacing.
