Well, if more than 5 minutes for sure it's bootloop.

Of course. UHD is ICS stock base, not GB. Did you use GB kernel?

That's why I'm prefer using custom kernel. Save the hassle.

Actually you don't need root access to install UHD. Just CWM needed.
Flash the kernel that already CWM included. Advanced stock kernel maybe?

You can download any kernel you like from here (ICS only of course )

You need root only to install CWM. But since you already unlocked your bootloader, just proceed with flashing custom kernel that include CWM.

Also can. Ganbatte ne.

In theory I think can. But not sure, why don't you give it a shot?
Just don't wipe any data when you flash the kernel.

Wow. So much trouble for you.
If and only if you can install LuPuS kernel.

Look on my siggy.
No need lorh. Unlocked bootloader is all you need to flash custom kernel.

Yup. I always do like that.

Using command instead?

Of course it will clash. But you won't boot into the system. Just flash the kernel, boot into CWM and wipe the system.
Then install UHD.

Nope, I mean using ADB/Fastboot.

Quite complicated problem you got here.
Never use CWM to flash kernel. Good luck.

Lel. As I thought your bootloader was locked.

Btw, I'm using a simple bootanimation only, just a glowing android. More fancy animation, more performance.

Yes. GB is the best. If only the UI is like ICS. I can't bear the GB UI. Especially in the Setting.

Never had any FC using UHD 5.0.1. Running fine here. Only used to read manga and watch some anime, and.. Whatsapp too.

I think UHD is the best stable ROM you can get beside stock GB and CM7.2.

I'm using SIO with smartassv2 249-1.018Ghz.
Don't have any issues at all.

Android stock browser is heavy. I'm using Opera Mini since it's much faster and using less data.
Btw, I also used all the apps from CM9 (calculator, messaging, dialer, browser, calendar, clock) because I think CM9 apps is much better than Sony stock apps.

Try wipe all the data, cache, dalvik cache, system, etc and reflash UHD 5.0.1.
Then uninstall apps that you don't use for more performance.

I have this issue also before. Always with the powerbank or the phone will die.

Buy new battery, issue still occurs, flash stock ROM, still same.
So, I read this one post on xda and calibrate my battery gauge.
Voila! No more issue. Using my phone the whole day now without any powerbank.

Heavy usage around 7+- hours, moderate usage can last around 18 hours. Minimal usage around 1 and half day.

In the end, I don't really know if my old battery is the real issue or not. Never bother to try to calibrate since I put in on the box already. Lol

Sorry. I don't bookmark the page. Darn it.

But this is what I did if I recalled correctly.

1. Charge your phone to 100% and fully drain it. Just use it normally to drain it to 0%. To make sure it's fully drained, try to boot the phone. Only red led will light up if the battery is 0%.
2. Take out the battery from phone for at least 30 minutes.
3. Put it back and charge the battery to full non stop (do not turn it on) .
4. Pull out the charger from the phone and plug in back for 5 minutes at least to make sure the battery is fully charged.
5. Boot into recovery, wipe battery stats (I'm not sure this steps is necessary or not)
6. Reboot the phone and when the when you see the Sony logo, pull out the battery. Then the charger.
7. Put your battery back and use it like usual.

I might missing some steps there.

CM12?
I barely touch my Xperia pro nowadays.
But I find it lag a lot right now since our phone is not capable to run modern apps smoothly.
Maybe will revert to stock GB or CM7 if I got the time.
