Another poll about battery life: first make sure you have done at least 4 full charge/dicharge cycles to make sure that doesn't affect results. According to the Apple the ipod touch 4g should charge 80% in 2 hours. This means that in 30 minutes the device should charge about 20% so assuming your ipod touch died with 15% battery life remaining, the device should have no more than 35% charge after 30mins. Keeping this in mind, after 30 minutes of charging is 1) your iPod 4G significantly charged to a higher percentage than it should be? 2) your iPod 4g does not seem appear to charge significantly faster than then its specifications.
