The battery life on my iPod Classic (160GB) is extremely low, I only last 3 hours at most. I used to get 18 hours easily, but after a previous update I've been having issues. I don't think it's just battery degradation because my device is only 2 years old and it happened suddenly, not gradually over time.

The aforementioned issues include:
-The disk almost always fails to spin down after 5s (my setting), it should not be in use I'm just sitting on the menu and playback is stopped
-The disk almost always works way too hard, spinning constantly during playback
-The CPU almost always stays at 216MHz with multiple boosts activated, even when idle on the menu with playback stopped

The battery meter has also been extremely inaccurate more often than not, sometimes doing irritating things like showing 28%, then shutting down hard and looping on the bootloader because the battery is in actuality at 0%.

While these issues almost always occur, on rare occasion the device does behave; the disk only spins briefly at the beginning of a track as it's quickly loaded into RAM, spins down and stays that way when idle, the CPU runs at 54MHz even during playback of FLAC, and the battery meter reports correctly.

I'm not sure if these are actually caused by hardware issues, but I don't want to spend money on a SSD and a new battery if it's software.

I turned off auto updating the database, and all the problems went away.
If anyone else has these issues, turn off database auto updating.

Hi there, I'm a newbe to this forum, I love the software - but - I'm having terrible trouble with battery life on my 6th gen 160 gb ipod since installing it. Max two hours use. I've checked auto update is not on and the screen is darkened after 5 seconds, version is e3c51e0-160804, and it was installed using the auto installer. I see this topic is closed but Im really stuck with this issue - hope you can help me. Cheers!!
