This ROM is simply the best ICS vibrant ROM that I have used to date. Have never experienced the mute/unmute bug, lock ups, random reboots, etc. with this one like I experienced randomly and untimely with Passion. And that's the reason I am still stuck on this ROM.
I'm getting anywhere from 15 - 24+ hours on a single charge with quite a bit of use, depending on how heavy my usage is. I typically run my phone on a single charge from approximately 6-630am up to as late as 300am; I ran this length of time both friday and yesterday with about 15% left on my charge. I run three exchange and two g-mail account on full sync at all times and am constantly here on xda.
The only time I experience the previously mentioned wake lock issue is when I set Screen Lock (under Personal/Security) to 'None'. The issue is not a consistent one; however, it only appears to be rather random although more often than not. Turning back on some type of Screen Lock fixes this issue for me.
And of course, as previous members have stated, there is the annoyance of media files being replicated within music players 4, 5, & even 6 times. Those replications do not play of themselves as they are phantom files but they make playing your media library truly a pain when you have to skip through several silent copies just to hear even a single song. As someone else suggested, using PowerAmp solves this audio file duplication problem for me.
All of that to reiterate that this work of art is the best that I have used to date. I think I'm stuck here unless something more flawless comes to light.
Excellent work dev/s! Thank you.
