Owning a Nexus 4 after 6 months

I have now had my Nexus 4 for over 6 months, when I first received it I was impressed with what you got for the money. But here are some points about it after owning one:

1. It sometimes switches itself off when there is loads of power and to switch it back on you need to connect it to a charger.
2. Battery life has improved over time, this might relate to switching NFC off and the latest update of Android.
3. Updating Apps sometimes removes them from the main screen and you have to add them back, this might be an Android problem.
4. After updating some apps the icon gets removed and you have to remove the app from the front screen and add it back in. Possibly another Android problem.
5. Android is not as nice to use a iOS.
