Extreme Battery Life Problem? - One (M8) Q&A, Help & Troubleshooting

For some reason, my battery has been very weird and unreliable recently. It will go from 80 percent to 20 perfect instantly and then cut off. It sometimes happens where I will open an app like Snapchat at around 50% and it will instantly kill my battery and shut my phone down. I have a picture of my battery stats right after my last cut off:

The phone was off for a total of around 3 minutes between it dying and being back on.
Does anyone know why this is happening or what I can do to fix it?
I'm running this rom currently on Verizon.

How many hours of screen on time do you have? Also, a screen shot of the history details is better for others to troubleshoot the battery.

If using this app to calibrate your battery, you should follow with this thread to get age to 100%:

[Q] Weird Battery behaviour

So I found my phone in my pocket had switched itself off or else I'd hit the appropriate buttons accidentally in my pocket to switch the phone off.. So I fired it up and noticed my battery power had dramatically reduced since the last time I'd seen it in the previous few hours. Then over the next few hours the battery level started coming back up when the phone definitely was not charging. It remained completely disconnected. Has anybody seen this before?
I have not tried calibrating my battery yet (should I?) and it is the stock one which cam with my GSM Nexus.

What is mmcpd/0 and why is it eating all my battery?

So, I've been finding myself losing ~50% battery in around 4 hours. Looking at Battery Stats gives me:

So... what the heck is that, and why is it eating all my battery?
What rom are you on?
Jedi Master X2. I also posted there, and the people on that thread directed me to Agni Kernel, which fixed my problem and then some (~18 hours on battery under normal usage now, which is better than it ever was.) So, problem solved, though I'm still curious why this just started happening all of a sudden (I've been on the same kernel for months with no problems before this week.)

Battery drain after screen repair

About a week ago my phone had to get its screen replaced and since then the battery drain has been severe.
I can actually watch its % go down - %50+/- in 1/2 an hour!?
I've tried with my spare battery and I see the same issue.
I'm going to the repair store soon to speak to them about this.
Has anyone heard of this happening - with any phone after screen repair?
I think it might not be an official screen they put in.

The above image was taken from %100 - screen off while at work.
There's a drop where the phone bugged out and had to reboot.
No battery hog services in the background that I can see
