I'm slightly worried that I have to charge my iPhone 4 every day. How long do mobile batteries usually last?

Lithium-ion batteries? Hard to say - usually, manufacturers claim anything from 300 to a thousand cycles. The BatteryUniversity breaks it all down.
With modern smartphones it's probably harder than ever to pin an exact number on life expectancy - every time you hook up a phone to a PC to sync, it charges a bit, and overall most phones these days need a full charge per day. In other words, after a year or so your phone's battery will definitely start to ****.

The battery should provide around 80% capacity after 400-500 charge/discharge cycles. Around 18-24 months with normal use.
The battery itself should last for thousands of cycles.
If it dies then you can still get it replaced or do it yourself.
