High android system usage at 20%.

I usually get android system usage at 1%, hence im freaking out. Help please! Could it be because i use vipernod, v6 supercharged and savagezen kernel?

I would say it could be any number of things, however the question is, what have you changed recently? Any updates, new apps?
Also, with this increase have you seen any decrease in your battery usage? I will have 70+% android usage sometimes but battery doesn't drain any faster. This is a normal thing for AOSP especially. Someone noted that they had high A.S. usage on a stock Nexus 4g.
This may just go away with a days usage, but be sure to check for partial wakelock. This option is in Spare Parts app not sure if its built in to MIUI. The wake lock is what kills your phone, when an app goes bonkers and keeps your phone awake.

True. Miui has updates every Friday. So yeah, i updates last Friday. I switched from tiamat to savagezen just so i can fix the high usage but to no avail. I can't check battery partial lock because miui has battery stats issues right now.

In addition to what imheroldman stated, charging your device will oftentimes cause your android system usage to spike, but 20% is nothing to be concerned with.

Screenshooters - Battery style

So i though i would post up this thread on what everyone is getting as far as battery life.
I see so many kernels and roms and i figure a great way to test them out is by having different users post up some screenshots of what they experience. Good or bad. But make sure to add some detailed info to your screenshot.
What rom, what kernel, what tweaks.
Maybe tricks or what ever.
Anyways here ya go.
ROM: AOKP Milestone 3
Kernel: Leankernel 1.8.0. 180mhz exp 6
Tweaks: Leantweaks 5.1 - zram, swap optimized.
Syncing apps: FB, gmail, exchange, xover, a few others. im not worried about battery life and here is why

You have been mostly idle with screen off and 100% on wifi. Awake and Screen on bars don't lie.

Yeap still amazing to me lol... first the fact that we now have wifi at work, and second it actually lasts past lunch time.
Reminds me of the battery times i got when i had my envy... almost

Team BAMF rom, stock kernel overclocked by myself to 1.35 with a slightly different method than what most use, GPU overclocked, standard voltage. Standard battery was used.
Pretty amazing right?
Some history:
9 hours as asleep in airplane mode.
11 hours was some fairly heavy usage with a mixture of 3g, 4g, and wifi. Usage included browsing the web, chatting on groupme, texting, and BT audo streaming via Google Music.
Not so amazing now eh? The only thing amazing about it is that it shows that undervolting is a waste of time.

Battery life and Rasbean/Trinty

How many of you guys use tethering with your Nexus?
As I sit here in the waiting room, waiting for my girlfriend, I decided to tether to my n7. After 1:40min my battery is down to 35%
Is this normal or is there something wrong?
What kind of battery life do you guys generally get when using rasbean and the trinity kernel?
Thanks guys for the feedback

This is normal usage with stock settings and stock battery. But I do not tether.

wow, I wish I could get that kind of battery life
I have to carry 5 batteries just to last the day...
But I remember getting 17 hours, but mostly standby with maybe 1:30 of screen time
are you using stock battery and have you tried the no-name brand?

I'm rooted with jellybam v7.0.0 with bms kernel. I'd call my usage about medium. On my e4gt I could get 20+ hours of battery stock and unrooted. Why is my battery life so poor on the s3? It's actually frustrating. I have it set to underclock at 192-192 when screen is off and it's undervolted -25mA at every clock speed. My brightness is always on like 15% no matter what. I only have my data turned on when I'm using it, that's it. I don't even have any game apps installed. My screen timeout is 30 seconds. Anyone have any ideas here??

Wake locks maybe? Get a battery monitoring app like Better Battery Stats (you can get it for free here on xda)

great movie

Anthrax on clean bean 2.3 with cross breeder. Some Wi-Fi, data always on. Auto brightness.
Updating to 2.7 when it drops since I already have multi window.
Also use Bluetooth to stream audio, and gps&sync on.
Oh. And I'm completely debloated. Makes a sizeable difference.
Used a safe to remove list found some where here.

What kind of battery life should I be expecting on a custom ROM?

I just got my Optimus yesterday and it's up and rooted with the latest bean stalk. Compared to stock, what kind of battery life should I be expecting?

What tomi001 said.
If you're looking for above average battery life, the the W0008 MIUI producer edition.

It depends on if you are running a custom kernel, and what all your settings are. There are many tweaks you can use such as Greenify & System Tuner Pro (to turn off your phone checking into Google all the time). There is an excellent kernel over in the General Forum. I run BeanStalk as well with TricksterMod. I posted some battery stats the other day running Lionheart Governor and Sio Scheduler. I had around 14 hours on a charge, which is excellent considering the amount I use my phone.
Btw, @Neroga definitely knows what he is talking about so I'm sure the MIUI rom is awesome as far as battery life goes.
