What's up folks. When I typically get a new phone I switch to GNL because I like the interface. On the other hand, zen UI is not terrible at all. I have ZE551ML..great phone all around up there with the best, but the battery drain is significant..can it be that I'm using the google launcher and zen UI is still using system resources? What have you guys done to optimize battery life? Should I go back to Zen UI? Thanks in advance for the input.
