I have also just finished replacing my battery with a 5000mAh version. I was able to do it with less modification as in the link above. It feels substantially heavier. I hope I don't get tired holding it :)I have it on a charger, I will have to see how the charging goes.
While looking the PC board over, I noticed there is an additional speaker port. I wonder if any sound is piped there. There is also a notification LED spot but nothing loaded. And the microphone isn't aligned with a hole it is just pointing at empty space.
If there are any requests I might pop the back off and post a pic and detailed instructions. The Russian ones are excellent of course but some bits were confusing. Now that I went through the procedure, I found alternatives that worked.
