iPhone

Hello! In general, my phone is already 17 months old, in the last 5 months the battery has been behaving worse and worse, if after buying a phone with all functions turned on, at maximum backlight with 3G turned on and frequent use, it could live for a day or even two, now all background what services are possible, the backlight is at a minimum, the mobile Internet is generally turned off and anyway, the charge is fraught just before our eyes, tell me what it could be? They say that this battery dies, if you put it on a cold table it turns off at 20%, on the street at 50% it turns off if it's cool, the phone has ios 7, never did a factory reset and did not restore it to a new one, they say in this could also be a problem.
