Slow as hell, batterie doesnt last no more.. Am i the only one ?
Patrick, try wiping the data cache partition first. Nexus 4: How to Wipe Cache Partition: http://youtu.be/x28zoyOy3-U. It should solve your issues . if not then try doing a factory reset after backing up your device with your Google account. Also battery life will get better over a week or two as is the case after every update.
