Same problem .Before the update i could play nearly 6 Hours, after only 1 1/2 - 2 hours!! I played a lot of gigs with G10, but now its useless for me! But now, i ihink :-) the g10 had a standby mode, if you did not Play. before the update it went only in standby , when the volumeknob of the guitar was at Zero .after the update it goes in standby mode if you did not play for about some minutes…… LINE6 FIX IT!!!!!
THX sooo much!!!!
