So before I misplaced my original s7 charger at a far away friend's house, my galaxy s7 has had pretty solid battery life on what I would consider relatively heavy use(turning the data on and off and sometimes using quickcharge) I'd be able to hit like 15 hours. Now since I don't have access to my charger for awhile I've been using my s4 charging block along with the chord that came with my verizon elipsis 8 tablet (the free tablet with the phone) The chord fits ok and the charge time is fine, but I noticed my battery life has dropped to like maybe 9 hours on the same usage. Is my battery now officially screwed up or should it more or less go back to normal when I get my original charger back??? I've also used another chord which chargers my phone EXTREMELY slowly(6 hour charge time) but I noticed the phone stays cooler when charging(although I have to bend the chord slightly and at the part in the phone or it wont work. I unfortunately once passed out on top of my phone and it got kinda hot so I'm hoping that didn't have anything to do with it I've researched that different chargers have different voltage specs(is that just the charging block?) I asked a lady at radioshack and a guy at verizon their opinion and they both said it would be fine but idk what to believe. Please shed some light on this and thank you for reading.
