How much does an iPhone cost?

How do I change the battery?

You can't. But we don't think that will be a problem for most users. Apple's official battery numbers are given below. But additionally the iPhone will still retain 80 per cent of its Lithium-Ion battery life after 400 charge cycles - that's a full charge followed by a full discharge. The iPhone's battery is no better or worse in this respect than that found in many mobile devices. Here are the numbers:

  • Talk time - up to 8 hours
  • Standby time - up to 250 hours
  • Internet use - up to 6 hours
  • Video playback - up to 7 hours
  • Audio playback - up to 24 hours

If you think you mobile phone usage is likely be heavier than that, then you'll have to forego an iPhone and buy something that enables you to use a spare swappable battery.

Apple UK says you can also get a replacement iPhone battery, should the worst happen, for £55.
