Ipod 6 - Swelling batteries a recurring problem

My understanding is that it is recommended that an iPod is not left on permanent charge. The iPod is not designed to be on charge all day. Quite the opposite in fact; it's a portable device designed for use away from a permanent power supply. That is, for a fully charged iPod to be run on its battery only, in order that the battery is correctly cycled (between full or near full power and low power).

Yes, you can use it in play mode while on a dock, even if fully charged, but repeated and extended use of it on a powered dock while fully charged is not the best idea.

The implication is that leaving it on external power when the battery is fully charged is bad for the battery and I believe that may possibly be the cause of your battery swelling issue.

I personally suggest that even if you unplug it from power at the end of the day, being on charge all day (but not all night for example) is still bad for the battery.

Hello KinTanTee,

There can be numerous causes for a battery to swell, though one of the more common causes is a battery being chemically degraded. Regarding repairs, you can review the following and Contact Apple Support for your options.
