Massive Battery Draw - Ouch! - Nexus 7 Q&A, Help & Troubleshooting

Decided to steam a movie last night from Xfinity. Started about 80+% battery. Running Paranoid Android, Trinity at 1400 cpu. And about an hour into the movie, I get the batter warning!
I thought I'd have plenty of time to watch a movie. BUT I was streaming, using wifi for it, and screen, etc. Is this kind of draw normal?
Any way to expand the time/duration? I would think I could watch more than one movie on battery?
EDIT: I put the device in AIRPLANE mode, and watched a two hour video, and lost 20% battery. I'm now watching it again (just running it actually!) to see how much more drop I get. Perhaps the issue is the streaming? My next test may be to lower my cpu speed, and watch again to see drain. Then stream again........ wow, I"m learning something!
EDIT 2: Watched a second time, battery down to 54%. Lowered CPU to 1100, give or take and starting to watch a third time. After about half of the movie, I only lost down to about 48%. Seems like big difference. An early conclusion might be I fell in love with CPU / High Q scores - and didn't need the juice for what I was doing. AND wifi streaming is a hog! We'll see how many times I can watch this before having to juice up. I'm curious how steaming at low CPU behaves. As I don't play games really, this may be the better choice.

Nexus 4 Temperature Issue

I currently have a Nexus 4 8GB on the Paranoid Android ROM, with Franco Kernel (Faster Binned CPU), the CPU temperature never seems to go below 45 degrees C works out to around 113F, When I'm using the phone for basic use this is just texting and using messaging apps no gaming whatsoever its on about 50degrees C. I tried to reduce the voltages by 150mV has no effect on the temperature what so ever.
This is my second Nexus 4 after the first had dead pixels, Do the temperatures seem fine, I mean a friend of mine has the same device rom/kernel and his device stays in the 30's ...
so whats the issue? your cpu temperature is smack dab in the middle of normal. your friend is either making up stuff, never leaves the air conditioning, or lives in a place thats cold. yesterday i was taking photos outside in the summer heat, and my phone hit 55C, also normal.

Thanks that's comforting...
just remember, human body temp averages about 37C, which is not hot. a quad core cpu can get really hot if being pushed, and still be "safe".

[Q] Problem with process "Multimedia" in Battery - Kitkat 4.4.2

Hello everybody,
I've looked everywhere on the web for an explanation of what has been happening since long time ... but I have not found anything.
Why I find into processes that "suck up" battery always "Multimedia" on top level?
I do not understand what could depend on .... moreover the percentage increases more and more during the days.

In the second picture there are 3 packages inside. I exclude the first two because I'm not downloading anything but I think it may depend on "Archivio multimediale".

I have a 32 GB MicroSD with stored music, videos and photos (many) but I thought that once phone start and it runs "multimedia scan" in background should no longer affect the battery consumption after it will be finished.
Please give me an explanation.
Thank you!
I woke up this morning to the same exact problem.
My phone went from fully charged down to 15% while I was sleeping in a little extra. 3 hours and it was dead.
Since then I have installed a few items. Particularly the Apollo app that CM makes you use.
The multi media crap has so far stopped.

What is the screen on time?
Didn't notice it , will update thread when charge cycle is at 15%
Looking forward to it.
I know gaming battery life may not be great. But for other use I think battery life is awesome.

I'm currently at 2d 2hr 17mins with 7hrs 26mins screen on time still have 26% remaining. That's with absolutely no gaming, only rooting, installing all my apps and setting it up. Also a bit of Web surfing and YouTube.

Should It be rooted in order to get your specified battery life?

How on earth?! I've had my Shield tablet for less than three weeks and I barely get 5 hours of screen on time.

Is it normal to have ~30% of battery usage by Android System + Android OS on Wear 2.7

i use a verizon wear24 (without verizon, with all verizon apps like msg+ and my verizon disabled). i dont use anything special apps other than agenda (1 calender), facebook messager, and whatsapp. no google fit, no tracking, no location. the wear24 has a 400mah battery which is decent , and uses snapdragon 2100 but i'm usually only getting barely 1 day of usage. i noticed that i'm getting 30% of usage in Android OS and System, what exactly are they doing that uses that much ? when the watch first arrived it was on android wear 1.5 , sadly i didnt use it much so i dont know IF it really is the OS causing issues. i upated it , and it went all the way to "2.7"
here is my battery usage (you can see i havent really been using the watch at all based on the screen % usage):

i'm abit disappointed at the battery life as i used to use the moto 360 (1st gen) with a very very old cpu and less battery capacity and it would easily last over 1 day.
Don't know what is to be expected, but maybe these tips will help:

Also, if you aren't using LTE on the wear24, you can disable it in Settings under Connectivity to save battery there too. This may need to be repeated with each reboot.

H870 running super slow and CPU seems kinda locked

Hey,
so I did research for like 3 days but I can't find any solutions relating to my problem. My G6 ist running on v30b so its updated to the newest version. But at easiest tasks it is so laggy and stuttering. Playing games you can forget about, also apps like Snapchat are a disaster. I deleted or disabled all bloatware I could find.
So I tried this CPU "benchmark" and it seems like the CPU is kinda locked or limited at 1GHz. The performance is dropping to red but the CPU still stays at the excactly same level, why? (Screenshot) The max CPU clock also says 1,59 GHz there first. The G6 wasnt hot at all ans not charging.
I was irritated and like 10 minutes later I started a new test. Now the Max clock was correct and it also started at 2Ghz but after 1 minute it dropped all the way down to 1GHz and stays there at the same level. The performance is completely red. I really cant unterstand why this is happening, hoping some of you can help me.
Thank you so much in advance!

Second test
Virus/trojan - run bitdefender or kaspersky scan.
Some adware/bitmining program. Full backup, then full reset of phone to factory fresh.
Something broken with the hardware - eg the cooling pipe inside the phone.
