I had upgrade my Android to lollipop. At first the device heat rapidly and keep hanging. It make me feel worse for upgrade my Android from jelly bean to lollipop. But after that I did factory reset and every then everything back to normal again. Happy ending for me :)
I received Android upgrade and did the same but after installing my phone started flickering (shaking) i did factory reset it has never worked almost aw eek now with flickering screen advise.
I don't face the heat issue or battery drain fast. My phone is working perfectly. I use my phone for office, social networking and taking photo and it lasts for two days. This phone is awesome. I m gonna stick with it until it's broken.

DO NOT UPDATE TO ANDROID 5 (Lollipop)!!
I really regret downloading the OTA Update to lollipop. the System UI alone will take close to 300MB RAM, all other OS modules and google service in lollipop also take up a lot more RAM, so much that under normal use, your home screen app will be killed and make your phone lag.
Despite it is called Project Volta, Jelly Bean is still more power efficient, I cannot even get through a day's use now.
Luckily there is a 3rd-party flashtool that was able to downgrade and save my phone.
4.4 above will also screw up your bluetooth headset, your song may leak out to the speaker during a notification and everyone will be able to hear what u r listening to, so not recommeded for bluetooth users.
to summarize, I don't recommend any Sony Xperia z1 users to upgrade their phone to Android 5 lollipop. If your phone is lagging, just restore factory settings.
Anonymous, 10 Jul 2015m4 aqua is better than z1,m4 aqua have 5mp selfie camera and its latest launched like Sony xpe... moreZ1 is much faster it has 2.2ghz quad core aqua only has 1.5ghz quad core and the z1 is a bet quad core because it's a krait as well z1 has better gpu, TV out. Z1 is the same as z3 except z3 has 3gb ram 2.4ghz and improved screen not a big difference z1 is in the high end class m4 aqua is mid class
