Iphone 5 battery. I went to future shop went I had warranty through them and they said it was ineffective. They watched a video for 5 min and it lost over %10. But they wouldn't fix it because the screen was cracked. But do they cover it?
You could try asking the Koodo shop if they'll send it out for repair but since the screen is cracked it's entirely possible that's what caused your supposed battery drain and they'll charge you for the repair.
Also speaking of this, I think you shouldn't have bothered with FS when AppleCare + is superior to pretty much everyone's extended warranty program. That rep obviously made a nice bonus to his commission by selling you that.
