Dropping iPhones: effect on battery?

[jellybean]

My iPhone 4's battery has, until now, been outstanding. But a couple of days ago I dropped the phone for the first time and since then it seems as though the battery is draining a heck of a lot quicker than it used to.
I've heard people say that dropping batteries can damage their ability to hold a charge, but can a single drop of the iPhone be enough to have had this much impact on the battery? (It was an approx 4 foot fall and the iPhone wasn't in a case, but there was no cosmetic damage it whatsoever.)

probably, I would take it to apple, tell them you dropped it and see if they will replace the battery

or you can lie and say the battery sucks

I'd take the high route and see if your honesty gets you a discount on the repair

I've not only dropped mine while it was in its Otterbox Defender case, but kicked it as well, with no problems at all to the phone or its battery. (I was jogging across a busy street and it fell from its holder because it was not clamped in correctly. A car was coming, and I didn't have time to pick it up, so I kicked it onto the shoulder.)

All that being said, a lot of luck is involved. Even in an Otterbox case the phone receives a shock when dropped. This can cause all kinds of problems outside of cracked screens or back. However, I don't think that the particular battery problem would be one I would associate with a dropped unit. If the battery did not work at all that could be caused by a drop, but just apparently draining faster is not something I would put down to a dropped phone.

To the OP,
Have you tried turning the phone off and back on, or restoring it? Also check how many apps you have running in the back ground. Double click on the home button and turn off all the program icons you see come up and see what effect that has on your battery life.

If all else fails take the phone to an Apple Store and if you want tell them about dropping it. It always pays to be honest, but I don't think this problem is one that could be caused by dropping it.
