Very slow charging and always show 100% battery
Hello from Norway. I was hoping someone could point me in the right direction on my battery problem. Storie goes like this: Had to replace the battery and follow the directions from ifixit. everything work fine for 2 days, but then it starts to charge the battery very slow. from 0-100% it takes around 13 hours. and the icon showing battery always say 100%. It works perfect running on battery, but only for about 1 hour and then the battery is empty. Putting the charger back it starts, but works very, very slow until i get more then 10% battery.. any suggestions on what i can do?
( I have tried al the normal things like calibration and smc reset )
Thank you and best regards
Sorry if this is the wrong way to do this, but here is a picture..
