Hey guys,

Trying to figure out if my battery might be on the way out.

I've noticed my battery life decreasing over the past 2 months so decided to try recalibrating the battery by letting it run out of juice, and giving it a full charge.

Immediately after this recalibration, the iPhone battery stats read as follows

Percentage Remaining: 50%, Usage: 5 hours 23 Minutes, Standby, 1 day 5 hours.

After around 3 weeks, my battery stats are now reading:

Percentage Remaining: 4%, Usage: 6 hours 7 minutes, 15 hours 33 minutes.

To me, after 3 weeks, the battery life doesn't seem anywhere near as good. I know Apple say to recalibrate the battery every so often, but don't feel that it should be this bad. It also drops very quickly as soon as it goes under 10%, I've seen it go from 8% to 3% in less than a minute.

I've recently switched to 3, but didn't think that would affect battery life, as the mast is at the end of my road, and very strong signal, so I doubt it's juggling masts or anything like that.

Any suggestions?
