So, I think my phone might be busted. Took it off charge today at about 12pm and it was totally flat, 0%, by about 7:30. Most of that time was just on standby in my pocket too, and even when I did use it, it wasn't for long, and it was only some light web browsing. It's also really warm and quite laggy and slow. Luckily, I've only had the phone about 6 months or so, if that, so I'm going to take it back to Vodafone tomorrow to see if I can get it repaired or replaced. Given its seemingly battery related, and all the goings on with the Galaxy Note 7 fire hazards (My phone is the S7, figures), I am a little worried about it potentially catching fire...
