Is it better to play iPhone games off the battery or wall charger?

I have an iPhone 4s. And I'm really paranoid about the battery. Is it "healthier" to play off a wall charger (or backup battery)?

I really don't want the battery to become crappy.

Keeping it plugged in all the time isn't good so I wouldn't do that.

  • When I unplug my iPhone wall charger, everything in my room turns off? Hi, I'm in need of some help fixing whatever is wrong with my circuit board or something, I have a futon bed and recently rolled over to the side too much, over weighing the bed and lifting up the right side. It hit my wall charger which may have messed up something, I'm not a wiring geek, nor am I good with wiring, I just need a way to fix this quickly so I can watch Netflix and play Xbox, whoever can help me with a quick simple fix will be much appreciated.
  • My iPhone won't turn on unless its plugged into a wall charger? My first issue is, my phone won't turn on unless its plugged into the wall. When it finally turns on after being plugged in it tells me my phone needs to be restored and that it can't make or receive calls until so, well great but, when i unplug it from the wall it immediately turns off and will not turn on when plugged into my computer. I've tried different USB cables but none of them work.
  • My iphone won't charge with a wall charger or just the usb? I have a iPhone 4, and i need to use it NOW. Its urgent and it won't charge. I tried the wall charger and it would only charge for like a second.same with the usb charger. I don't have time to buy anything at the moment i just need instructions, please.
  • My iPhone will not charge via wall charger? I have an iPhone 4S that will not charge via the Apple Wall Charger. I took it to my local Sprint store and the guy there said it is the cord and he could sell me a new cord, then later I took, it to the Mall of America Apple Store and they said it is the device itself. I have already tried a reset (to no success ) and am doing a restore, what other suggestions do you have?
