[XPERIA X2 General] damonous:
I have not had battery problems with X2; I've used it since Aug 2010. I always have bluetooth on, and connected to my BT watch, BT car stereo, or BT home phone. I have LOTS of stuff installed, and a 32gb SD card. I've been known to run certain apps for 2-3 hrs straight with screen on and still have some juice left over.

In all, I enjoy the phone for it's sleek design and excellent flush screen more than I did the X1 (I bought the X1 the month it debuted, and still have it). The keyboard is absolutely untouchable. That alone is something that makes any kind of bugs something you say, "I'll have to search for a fix for that," rather than, "I better get a new phone".

If SE ever really focused on fixing the firmware one more time, or present an Android option ...the X2 would stomp all over similar devices.

But, there are indeed many core issues with this phone that you have to surmount, even after upgrade to MR2 firmware:

1) Fix for the SD Card corruption-bug

2) Fix for the display backlight timeout not being controllable.

3) Fix for forcing the screen to go off, but not the device to 'sleep' (this helps with certain BT & wiFi connections & software)

4) Add software to select programs for auto-rotate w/G-sensor

5) Add Opera

6) Add Advanced Config to tweak system

7) It's better if you overclock it.

8) Add SK Tools for system maintenance

9) Add JetWare bluetooth extension in order to transfer contacts to car stereo (I had to do this with X2; didn't have to with X1)

Items 1-7 are all freeware, although some may be hard to find.

That being said, this is Windows Mobile...so not a real big surprise that you'll have some issues. If you want real 'freedom' with your OS, ...this is what you'll need to work through. If you want trouble-free but vanilla computing, get an iPhone.;)

The comments above by gbajzelj & robuash are extremely valid, on the opposing ends of view....

A note on SlideView: this is essentially an extension of their media panel from the X1. While being a frustrating and buggy piece of software as people say, ...it's slick as Hell. I mean, I don't want to delete it (or the whole panel interface). It's why I bought the phone. I just think it's ridiculous when people say, "Fix your X2 by deleting SlideView and all Panels". --Oh, Thanks for that.:rolleyes:

Just understand: you do need to buy a standalone photo viewer (Resco is great), and if you can't learn to love Windows Media Player, then expect to buy something like Pocket Player. SlideView is great for a handful of files, but not if you want to spend a lot of time with it. By that time, it will generally have cataloged some file it didn't like and crashed.

SlideView is launched if you press the hardware panel button once; panels are called by pressing the same button twice in quick succession. This could be better. Especially if your phone happens to be bogging-down at the time, ...you might not get the desired result on the first try.

A note on MR2: The firmware includes the "Saturn" black/gold theme from SE, which totally changes the look of your WM6.5.3 interface. It is slick, and it smartly increases fonts in correct areas, while making WM look modern. MR2 however, does not make the X2 magically 'fast'.

And, I think robuash is talking about the type of fixes I listed above. You will need to spend time tweaking. As a matter of fact, after running since about Sept, ...it's about time for a reload from scratch to clean things up. When I have 8hrs to spare, I'll get around to it. (Maybe I'll take a day off from work sometime.);)

Lastly, I think someone above mentioned memory. As opposed to the X1, internal memory is very limited on the X2. You have to be real creative how you install stuff, and install absolutely everything you possibly can on the SD card instead of the system. (This is also where SK Tools comes in handy, because it lets you 'move' programs between Card and System & back, even for some programs that don't give you a choice at install time.)

Also, once you dip below 20mb program memory in the phone, it tends to get real buggy. I'm just above that right now, but I've got LOADS of programs installed (creatively, on the SD card).
