[Nexus 4 General] Armalong:
I'll start here with something I already have and then will post more text and pictures while mine project continues.

I thought about replacing original battery with battery with bigger mAh capacity and found this topic. I liked they way the OP made his phone, read all the topic, started reading some stuff and decided to do the same. Ordered battery on ebay (http://www.ebay.com/itm/181839893052 , still doesn't have it) and multimeter (http://www.aliexpress.com/snapshot/6962326170.html?orderId=69741195993066). Also asked friends about electronics, soldering and battery things because never actually knew how it worked. And practiced with some other electric stuff to not to break phone in moment of truth. Removed my N4 back many times, following this video (http://www.youtube.com/watch?v=AZDAIgwbXk4 it's long, but well made), did some measurements and checked how all the antennas are placed there. Going to keep NFC and QI using some pins from old laptop or just wires. Also read the article about replacing phone's back (http://xdaforums.com/nexus-4/general/how-to-nexus-4-replace-cover-glass-t2257896) to be aware of how to move antennas from one back to another.

About back. Since we don't have here in Russia 3d printers much, especially in small city where I live, I've made a decision to make it of wood. May sounds strange, but I found this idea fun =) It won't be full back replacement, but additional block on top of place where back glass is now. Here is a sketch to make it clear.

I even made simple version of back just to practice and felt if I could do this properly or not. Here is my monster:

It won't fit of course and I found a master who can do this work carefully, it was a lady from Crimea. She and her husband do all the stuff from wood and you can oder them any shape and even choose type of wood.

I did sketch with all the measurements and sent them, here it is (http://aleksey-yaremenko.ru/uploads/render/3.png), you can just print it on paper with 100% zoom and it will has real size and fit phone.

After few days they finished this thing and sent to me, I'm still waiting.

It's made of juniper, it's good for your health to inhale smell of this wood =). I asked them to left some extra place in the left top angle (green dotted polygon on a sketch) in case I'd add some extra things inside.

This back costed me 30$ with delivery, I believe it's cheap, because order is quite special and wood itself isn't cheap too.

Looks like this additional back going to make my N4 two times thicker but I don't mind since it has large battery =)

Finally got my back, it fits almost perfect, only edges have little gaps, but I'm completely satisfied, I thanked people from Crimea who made this. Didn't do anything with it yet, just attached it to the phone.

Continued to do my deed. Still have no battery and multimeter, anyway decided to screw wood back to original.

At first I positioned new back and fixed awhile with scotch tape.

Then melted 4 holes in plastic using nail and lighter.

There still glass left, I drilled it. Used for it device for nails. Even it was perfect instrument I thought I still got cracks. But I didn't mind, anyway this glass would be partly removed.

Then I placed wood to the back again and used needle to mark place, where hole for screws should be (marked on picture below with red circle). And also found good screws and plastic cylinders (don't know how to call it even in Russian) for them, they were taken from broken CD player.

Last thing I did was gluing cylinders to wood surface, using needle as a guide.

Then two backs were screwed, unfortunately not very accurate first time, so I had to paste up and then glue it again, after that it fit well. Anyway I'm planning to fasten these backs also with double-sided tape beside screws.

That's all I have by now.

Hope all the pictures are available.

BTW I wonder is there possible to solder microsd reader since there will be extra place in new cover back. Reading this article this moment, it's for nexus 7 but might have some interesting stuff (http://rootzwiki.com/topic/30797-op...in-micro-sd-card-reader-to-nexus-7-build-log/). Any ideas?
