New droid z force

Hello everyone. I'm new to forums. Got a new phone last Friday and I'm loving it. Got the update N Saturday but haven't installed it yet. I have been reading on this and other forums that some people are having issue with battery drain faster and phone freezing up. Don't want to install and start having problem with it. And I'm having a hard time to hear notification. It's so low I can barely hear it. I got the volume turn all the way up Any comments would be appreciated. Thank you
