Questions about speaker/battery replacements and a few other upgrades

Hi, I own the 2014 14" Razer Blade and my battery life has begun to degrade, I`ve already lost around 20% and am having trouble getting through extension subjects. Based upon this teardown, https://www.ifixit.com/Teardown/Razer+Blade+14+(2013)+Teardown/22591, it appears that the battery is easily replaceable and isn`t soldered onto the board. I`ve also read on Anandtech that the 2015 Blade has much improved speaker performance and based on the same teardown they are also a plug-in component. My question is whether the 2015 Blade speakers have the same connector? or a connector at all now and where to buy these new speaker drivers and/or battery. I`m also looking into replacing the Intel wireless chip as it has poor synergy with my home network (on multiple computers with this chip) and my 2013 Blade had great WiFi performance with its Killer wireless card. Does anyone know if you can swap these cards and if the bios white-lists parts. Thanks in advance for any responses.

 

I don't know for sure, but I would say all the mods you want to make should work and be straight forward, just wait for someone with a 2015 Blade to post pictures of the connectors, battery size etc.
I guess the most difficult thing about those mods will be to find the parts to buy.

I read somewhere that the physical speakers are the same, but they changed some power delivery or something, I'll have to look for the article.
