So i recently bought a pre owned iPhone 6s and last night it went blank but the time, carrier and battery percentage only showed. I tried to turn it off or click the home button but nothing happened so I reset it by clicking the power button and home button and it was fine. But the battery then stared to drain quickly when on YouTube and when I'm on YouTube the battery never drains so fast until last night. I've bought a pre owned phone before and never have had this problem. Should I report this for the warranty I have on the phone?
