The thing on an iPhone that sucks the battery down the most is the display. If you are using it to play a game, just the fact that the screen will illuminated with suck down the battery.

  • Why does my iPhone 5 drain battery even when I don't use it? My battery keep running out even when I don't use it. I tried to turn off location services and brightness and stuff but doesn't really help. What should I do?
  • What are some cool iphone games (that don't use internet)? I don't really like first person shooters, but not all those stupid "college campus" or "hello kitty cafe" or "temple run" stuff. Slender was pretty cool, but kindof boring after a while. I have a half hour bus ride to school every moring plus waiting at the bus stop so any cool apps would be appreciated.
  • Is it weird I don't want a lot for Christmas? The stuff I want isn't like big things like PS4s and iPhones. I mainly want stuff to do with my favorite band, because I love their music. I want: CD's (I have a list of some of the ones I want) Posters of my favorite band Super Smash Brothers Brawl (for wii) Biographies of The Beatles iTunes Gift Card DVD's and Money Seriously I don't want a lot. Just Beatles Albums, posters, biographies, money, and Super Smash Brothers Brawl.
  • IOS games with a lot of upgrades and abilities? Ok i have an iphone 5 and i like games where you can spend in game coins and get upgrades to make you better, ex: rediculous fishing and infinity blade. Please do not suggest puzzle games because that's not really my style, and i don't want to spend more than a few bucks per game, but if you can think of any games with a lot of upgrades then I'd really appreciate it!
