Galaxy S6 suddenly charging very slowly.

Let me start by saying that I'm using the original charger and cable, and that I haven't made any modifications or added any new apps recently, but I did receive a very small update about a week ago. Anyway the phone suddenly takes ages to fully charge. Last night I plugged it in with 45% charge left and it took more than an hour and a half to reach 100%. Normally that would take 30 - 40 mins... Is there any way to fix this?  I have the phone on contract but it's over a year old, so I'm guessing it's out of warranty..

@Yellowmatic

 

Go into settings and turn Fast charge off and then back on. This might kick it back into play.

Hi, 

 

How many background apps do you have running? 

 

Also go into battery stats under settings and it will tell you what us using power. Look out for media server for example. 

 

Thanks

Thanks BrendonH that did the trick! Charged from 20% to 100% in less than an hour. I looked up a few solutions and they were all quite extreme and laborious. 

Nice one! 👍

No problem @Yellowmatic

 

Update may have caused the issue.

 

The next trick would have been to wipe cache. That wouldn't delete nothing though.

Before we put this one to bed I'd like to share one of the "causes and solutions" I've come across.

 

"Re-calibrating Your galaxy S6: You should not allow your Galaxy S6 battery to die completely or even get extremely low each time you use it. Performing regular charge-up will extend your battery’s life.If overheated or overcharged, Li-ion batteries may suffer thermal runaway and cell rupture.

How to Re-calibrate your Galaxy S6 Battery?

Manufactures normally recommend calibrating every 2-3 months to , this is completely draining the battery of the Galaxy S6

  1. Plug in original charger into your Galaxy S6  VIA Power Supply .

Any veracity in this? Seems even a little contradictory to me...
