technology 20 days old s5 battery: advice?

[xjaopony 0]

My spare Galaxy S5 OEM battery got from ebay suddenly going from half to zero. I haven’t gone into such situation while using the mpj extended battery and original battery. When the phone is switched on it shows 1%.This battery is just 20 days old and I suspect the battery has reached the end of its life:(20

I would recommend calling your service provider, they can help you with any technical issues or questions you may have, probably run some troubleshooting as well.

 

If all else fails, they'll probably send you a new battery free of charge.
