Most phone batteries do that. It's the phone not the battery I believe. No downside man
 
Not quite.

The nfc chip is in the phone, but the antenna is on the battery

Ah. Guess it still ends up causing the same result if you dump the Samsung battery.

Yeah, it's the way the phone is charged.

I don't remember the name, I think it may be called a floating charge but I'm not completely sure

But it helps when you charge it in an external charger

The OEM battery doesn't do that. Mine was at 100% for close to two hours on stand by. But everyone's experience will be different.
 
Yeah same my stock battery stays at 100% for a while with me doing multiple stuff at once.

I've unplugged my phone after charging it overnight with the battery at 99%. I can't remember it happening with my iPhone, but I think those chargers work differently.
 
the phone just needs calibrated to read the % on that battery properly i think mate. no point doin it if ur gona swap between that and the stock one though
