In the midst of the iPhone 4 craze, we became impatient and decided we needed to tear down a phone, you know, just to keep us in tip-top shape. And lo-and-behold, the Sony Ericsson Xperia X10 Mini E10i.
A big thanks to Brian at EDN for providing the phone for this teardown. Be sure to check out his Xperia X10 Mini Preview!

he great take apart, do you need to dissemble the whole phone to replace the power button cap?
More or less. It's been a while since I took this apart, but I think you'll have to take the logic board out (work up to step 9). Luckily, this phone is really straightforward to disassemble.
so you can't use BST-38 Size: (5.5 x 48 x 40 mm) battery instead that one you have on the picture (or BST-41 some sellers on Ebay say it is compatible) ???
great guide, helped me replace a squashed LCD screen by working through and then going in reverse, thanks!
Hi There
This is a fantastic guide, and has enabled me to get the battery out, does anyone know where on earth I can buy one of these, I have searched all the usual channels, google ebay etc, but can only find batteries for other models that look nothing like this.
Any help would be much appreciated
All the best - Trev
