While I do have Phase 2, I don't routinely listen to Phase 2 (not in my area). However, I've recently starting adding background colors to most talkgroups and recently even enabled full time back-lighting. My battery seems to last so long that when I travel - even on long trips, I don't even bother to plug it in anymore (I bring my cable but almost never use it on the road). (Still) very impressed by the battery life.
And while I am at it - again, since the Phase 2 upgade/firmware, the audio is better than ever! I will note that for my local system, I occasionally hear a voice call that sounds very strange and often wonder if that specific radio is different/non-standard and/or damaged in some way.
