Is it worth rooting the Xperia Z?

[HonestObjection]

I've never Rooted a phone before, but given the right instructions (which there are plenty of) I don't believe I'd have any trouble doing so. I've just got a few concerns I was hoping someone could clear up.

• Can you Upgrade to 4.2.2 (if/when it gets here) on a rooted phone?
• Will it cause me to lose any existing features?
• Is there a significant chance of bricking it?

I'd quite like to do it as there are some apps I'd like to use which require Rooting (such as screen off when using MHL) and also to install a patch enabling the phone to read exFAT as I've had enough trying to get 4GB files onto FAT32, so really I guess is it woth it?

Also does anyone know of a reasonable capacity battery at 1.5A 5V as the sony one seems a bit small and expensive by comparison to some others. Or if USB cables would bottleneck a 2A to 1.5A this may be a completely stupid question, but it seemed logical in my head...

Thanks for any replies!

  Yes you can. This is not an issue.

• Will it cause me to lose any existing features?
  As long as you stick to the stock or stock-based ROMs, all existing apps & features will work.

  Rooting is essentially "removing access restrictions" that are normally in place. An equivalent example to rooting is just like having Administrator access on your windows PC. Which give you access to system files and folders. Allowing you better customisation and control. But this also means that you or any app you install can ahve full access to the system softwares. So the most it can do is soft-brick. If that happens, just flash the ROM again.
  
  

The first thing that you would want to do is backup all your apps using Titanimun Backup. After that, if you're up to it, get recovery and backup your phone. While the first option allows you to have backup of all your apps and data, the second option allows you to backup the whole phone. Allowing you restore everything easily, should your accidently soft-brick your phone.
