Nice! Lets hope that us S owners get this update today as well!
Probably won't be for a few weeks though
How much would it cost to go from a HTC One X to XL if you considering selling or trading in?
At the moment on my phone I'm getting 3-4 hours of using phone with about 15 hours total battery untill it's dead.
I was on it solid for 2 hours last night, downloading updates, browsing Pulse (news feed app), watching videos on youtube for a good 30 mins, tinkering with settings.
Is that good battery life?
**edit**
HTC One XL slower?

Not sure, I don't think there would be a huge difference in price between the 2.
And from what you have said there about usage and battery life, I would say that is pretty good! Although need to know screen brightness and wifi connection time or/and mobile data connection and what your signal is like?
Nope, the XL is actually faster than the X. Might be dual core chip, but it is next gen chip; more performance per core (more important than an extra 2 cores as hardly any apps still fully/properly utilise dual let alone quad) amongst the more techy. features of it and as a result, everything on the mobile feels more snappy/instant and certain tasks are performed quicker, battery efficiency, heat given out, are all better on the S4 chip and better than the exynos quad in the GS 3.
I thought GPU performance was better on the X and much better on the GS 3 mali GPU but Sarge says different, his favourite benchmark
Plus the S4 chip appears to be better optimized overall for sense/XL/S.
Anyway, here is anandtech's review of the XL:

You can see the battery and performance benchmarks, although I always take the battery benchmarks on expert review sites with a big pinch of salt
As for real world usage they don't quite pan out to be what they say. IIRC, quite a few people are able to get up to 6 hours on screen time on the XL (auto brightness) with general usage i.e. browsing, videos, games.
Your phone unbranded/unlocked? There is some method about changing your CID number or unlocking the bootloader to get the update or something along those lines anyway
