The OTA downloaded last saturday, but I was hesitant in installing ICS because of the several bad reviews about battery issues. However, tonight I said the heck with it. If it screws up my battery life, I can exchange it since I purchased from Costco, and I have close to 2 months before the 90 day return policy.
I must say, I LIKE IT A LOT!!!! It feels snappier and I just like the overall feel of it. I've been playing with it for about an hour, installing some apps and looking around, debating which launcher I want to use with ICS. No report on battery life yet. I will do a full charge tonight and report on that later.
For those that have not updated yet, I backed everything up and did an FDR prior to installing, and I was not rooted. I was planning on doing another FDR after the install, but decided to not do that at that moment. I can get close to 1 day, 18 hours with moderate use before recharging. Hopefully I can get close to that with this update.
