I changed the theme last night and it and just plugged it into my laptop. I have never seen this before. I did do a search and found some things regarding a lightening bolt but not a yellow one. I am thinking that perhaps this is just a new way to show it charging but wanted to ask. My 8330 is approximately 2.5 weeks old.
That just means it is charging. The icons will be different colors depending on the themes. The lightning bolt through the battery shows it is charging. When the lightning bolt disappears, it is fully charged.
