iPhone 5S Battery

Recently I've thought my battery seems to be dying much quicker than it used to, and my iPhone 5S is nearly a year old. Seems about right. I chatted with Apple online, they received diagnostic info, and told me the battery is fine.

Then, I downloaded the iBackupBot app to get the real numbers, and it says my battery has 283 cycles, original capacity of 1550, and current capacity of 1500. Does that seem right, or even possible? I'd expect a much lower current capacity after 283 cycles, so I'm wondering if the numbers Apple got are even correct.

I don't want to go to the Genius Bar unless I know my battery is worn/defective, so I'm trying to get more insight. Does it seem like my phone is reporting incorrect info on the battery?

Yes, it is possible and it's right. There is nothing wrong with your battery...after 280 cycles, you couldn't wish for more.

Yeah that's why I'm confused. It seems TOO high.

Compare your usage to the tech specs:

Talk time: Up to 8 hours on 3G
Standby time: Up to 200 hours
Internet use: Up to 6 hours on 3G, up to 9 hours on Wi-Fi
Video playback: Up to 10 hours
Audio playback: Up to 40 hours

Are you not getting these numbers? Note that they say "up to". That's because there are variables beyond Apple's control. Just like MPG in a car. The best example is power usage for talking and cellular data. With a strong signal (5 dots) your phone will only use 50 mw, and should get these times. However, with a weak signal (1 dot) it needs 10 times as much power (500 mw) to maintain a connection. Clearly this will drain the battery much faster. The greatest battery drain occurs when you don't have a cellular network connection and the phone says "Searching...". The phone must search at full power.

It's not. If you go about it in a sensible way, it'll be only slightly lower when you hit 500. These things can do a 1000 cycles and still have acceptable capacity left.
