The main differences between those two generations of iPod Mini is battery capacities and the storage.Both versions have 102 grams weigh. Second version wasn't available any more in gold because it was not so popular.
There is a small difference with button labels: for the first generation was grey and the second had button labels matching the case's color.The iPod Mini uses Microdrive hard drives (CompactFlash II) and it is capable of storing 1,000 and 1,500 songs.
Because in the first generation there was a problem with battery life, Apple addressed the problem in the second version. So, there was an improvement and for the second generation models battery life rised up to 18 hours. It also had a headphone jack, a hold switch. The iPod Mini is compatible for WAV, AIFF,AAC/M4A, MP3, and Apple Lossless audio formats.

Replacement batteries was available because the capacity of batteries decreases over time.If people decide to send their iPod back o Apple for replacement batteries, they have to pay a lot of money because the charge is very expensive. But there is another solution- they can find on the internet many manuals for battery replacement and a lot of outlets selling compatible Lithium-ion batteries. Many of them are of higher capacity than the originals.
The iPod Mini can run iPodLinux or Rockbox firmware. It allows music to be played directly on the iPod and it is not necessary to use iTunes any more . There can be replaced the 4 or 6 GB Microdrive with a higher one with capacity 8, 16, and even 32 GB cards. The fact that the capacity has increased was an advantage and a reason why battery life also increased.
