I will use it in the evening and then won't touch it for a day. Then I go to pick it up and its off. I can turn it back on by pressing the power button a dozen times, it never boots up after I press it once, the thing vibrates but won't turn on. Its not the battery, because it'll turn on and still have charge.
Its getting really frustrating because I don't know what's going on. I'm stock on 4.4.2 not rooted, but unlocked. Any new apps I installed, have been removed. How can I figure out what my issue is.

If it is easily replicable than the first step would be get a logcat and last_kmsg of the event

So I installed a logcat app (aLogcat) and it crashed this morning. How do I make sense of all the info on there? How do I know that this is the info to help determine my issues?

That's not what you are looking for, I mean yes that's part of your log but you need to run the log while its happening or last_kmsg right after it happens, or really both to help narrow down for sure.
Get adb up and running and use this to capture both. If it crashes try to see if adb is functioning while in this state, if so capture the log and post it here

I really wish I knew what you're telling me. And that link provided earlier didn't help me much either, way too much info on there for me to try and decipher it. I'll tray and Google at some point to try and figure it out. I'm pretty dumb when it comes to these things.
But, how do I run the log while its happening? The thing is shutting off in the middle of the night, and I don't even know when it happens. Keep the app open until it happens?

The link I sent you also had other links in it that showed how to use adb. I would use adb over an app for your situation

Hi there
Yesterday my phone just went from 14% power (after giving me the usual battery warning) to 4% in like two minutes. The other days before that, it's been very shirt time as well.
I don't turn anything off (like 3G, sync, etc.) when I get the 14% warning, but going down 10% in few minutes seems a bit extreme.
Have anyone tried the same? Or can someone explain why?
Thanks in advance.

Well at least you have no deep sleep issues. It can happen after a deep sleep period that the battery levels indicated are not up to date at the time it wakes up. Then comes a correction of the actual battery level.
Sv: Battery goes from 14% to 1% in minutes.
Okay, thanks a lot for the answer. So I should only begin to worry if it continues?

That probably will not happen, usualy only after a longer deep sleep period.

I keep my GPS off to help my battery life, but every once in a while the GPS turns itself on randomly and tries to get a lock. It's an issue because while I'm inside it really struggles to get a lock and eats battery like a mofo. I got to work with 97% battery and an hour and a half later I now have 85%.
What can I do to stop this from happening short of waiting for cyanogenmod?

Install System Tuner, free from market (lots of annoying ads, no big deal).
Click the red System Android, click Android System, Details, then uncheck all 7 CarrierIQ related processes.
Worked OK for me and no FC issues with calls or anything.

I purchased a nexus 7 recently,updated to 4.3,locked and unrooted as of yet. I currently have 2 user accounts active on it. Since my first 100% charge, I have been getting tacky battery life. I follow the 100% charge and discharge till 1% method. Overnight with WiFi on and all apps closed,I'm getting a drop from 74% to 57% . Looking in the battery stats doesn't help as it doesn't show any unusual ongoing background activity. I'm also getting around 6 hours Screen on time,I could never exceed this mark. I only have the customary Google apps,Facebook,Twitter, instagram,pulse,and 3 games installed. What can be the reason of this ?
Sent from my Nexus 7 using xda app-developers app
Those apps keep running.. Also some third party apps push ads and also turn screen on, which could drain battery..
For better battery life, you can turn wifi off if not needed,.
Sent from my Nexus 7 using xda app-developers app
I tried with WiFi off one night, I got around 9% drain still. I kept the sync interval at the maximum in every data fetching app I have installed too.
Sent from my Nexus 7 using xda app-developers app
You might well try the app Better Battery Stats, and see what it believes is keeping your tablet from going into deep sleep. 9% drain overnight is not terribly excessive -- it should be more like 5%, I guess.
My 2012 nexus 7 had 51% before I went to sleep last night and when I woke up this morning it was completely dead. I didn't even get a charge icon when I plugged it in to charge. I had to leave it for an hour then tried again and it fired right up.. Hope I can see what's causing the drain with better battery stats
Sent from my Nexus 7 using xda app-developers app
I was using mine once in the morning,when the battery hit 4% it suddenly shut down. I tried to charge but the battery icon wouldn't show up. Started it finally using the tips on the Google support site. Must say,I've been plagued with battery issues. I'll try a factory reset and while on it unlock the boot loader too.

I checked with BBS with WiFi off overnight. "PowerManagementService.wake lock" is keeping my N7 awake. Any solutions?
EDIT: I checked in partial wakelocks,AudioOut_2 was the highest at 30m runtime.

I have about 100 apps installed in total, and 2.5GB free out of the 12-13GB availible. About one week ago, the phone started to lag in Fifa14 and other apps. It even gave me about 10 bug reports! Why? Responds are highly appreciated!

Please help!
Sent from my Nexus 4 using XDA
your apps are the reason, was the phone slow prior installing 100 apps?, how many are running in the background and how much ram is avaliable?, you need to make sure they are not running when playing fifa.
backup your apps/data and remove them and see if it helps,
Are you rooted? If you are, I would say download greenify and greenify apps to save RAM and hopefully make your phone faster.

Between this I've a total of 414 apps in my nXs4 and in my Purity and stock kernel, everythings breeze. It takes some time to boot yet works fine for me.
Salutations...
Nitty gritty...
I heard/read somewhere that once you reach 50% capacity of your storage that your Nexus 7 would have performance issues...I think I may have that issue...I've deleted what I could and and have freed up more than enough space to consider my table almost empty, but, I still have performance issues. I haven't been able to confirm the theory nor have found even an inkling of a thread to address it. I can't pinpoint any other reasons for my symptoms like a bad app or anything...I'm not rooted,
Symptoms include:
Very laggy to no response with touch...
Occasional freezing that requires power button holds reset...
Touchscreen acts as if a toddler was scribbling with a crayon(hard to describe) but without moving my touch point...
....
All this becomes very frustrating...any help would be very appreciated.

Just try deleting cache/dalvik cache and reboot.
I'm not rooted, how would I clear the dalvik cache?
