Im on serendipity 5.10 and I flashed speedmod k13b using odin and k13c using sgs kernel flasher. I notice battery drains 1% every 10 min and charges up at the same rate. This did not happen when I originally flashed the first time (serene 5.10).

I will actually test it a couple days then I'll see.

6% an hour does not sound to bad for me ^^ but i highly doubt that it takes over 10hours to charge your phone

How are you gets getting such high battery life?
I went back to speedmod k13a cuz it seems to have better battery. From what I read, the kernel needs time to adjust after some flashes so let it charge/drain a couple days and it'll be better. I did that and i seem to have better battery.
Edit: not significant though. I'll test it more.

Is this idle drain?
all depends on your use and rom. I get about 1-2% drain per hour idle using whats in my sig along with juiceDefender to turn off data (cell and wifi) when not in use.
Last night I charged my phone and unplugged it around 6:30 am, but used it for maybe 10-15 minutes total for some calling and light apps like iGag, but as you can see, Android OS drained almost 30% of the battery while the phone was idling.
What exactly is Android OS, because I can't find the exact apps which drained the battery so badly. Any apps or advices for detecting the troubled apps or an advice? Thanks guys. :good:
Try battery stats plus from Google Play.run it for while, it will calculate which apps are draining your battery most.

What would you guys recommend as the best kernel for battery life??

Yeah I've read that already but I've also read that the motley and omega kernels were the best but this test says otherwise. So I was just seeing what the majority of people would say. Do you have any preference for a battery saving kernel?

Franco's kernel is giving me pretty good battery life. Down to 17% with 4 and a half hours of screen on time and almost 5 days since last charge

Wow, I have about 6.5 hours of on screen time and like 16 hours total since last charge and I have 9% battery left. And I flashed some stuff and rebooted like twice so I'm sure that took up some battery too

Battery life is much more relevant to how you use your tablet than the kernel. I get anywhere from 5-8 hours display time depending on if my usage is more gameplay or more browsing. The only kernel I actually saw a significant difference in battery life under same usage was faux kernel, performed well but my battery died noticeably quicker.
I now use omega 3 because it gives me faux like performance with stock like excellent battery. I used stock for the longest time, and still would if battery was my ultimate priority, but omega 3 smooths out some games and just about equals stock on battery life. I've never on any device actually had a custom kernel improve battery life over stock. What effects your battery life from day to day is primarily the days usage.

You are saying bull**** im sorry, but you never saw any kernel improve more battery than stock? Oh my god, what world you live?
Im a testing this every day since Galaxy S2... So i know what i saying...
I have the N7 5 days, and i test kernel stock for 3 days and i got 6.5h screen on time, after i installed Franco R42 and used the tablet the same way and i got 9h screen on time, now im testing intersect kernrel and i have 85% with 2h and 30min using the same way always
Resuming, any good custom kernel is better than stock.
Enviado do meu Nexus 7
my choice is still m+ kernel http://forum.xda-developers.com/showthread.php?t=1937146
I get screen times around sometimes more than 8+ hours with normal use ( web not high power consuming thd games)
This kernel supports man adjustments like undervolting and setting the frequencies.
its works with trickstermod which lets you even deactivate some Cores. Im running undervolted, underclocked
With just two cores without lag or something.
Give it a try

Lots of little changes in settings, uv, minimal frequencies for CPU, and no heavy gaming, not a lot of videos either

All your opinion based on your "said" usage. Fact is I got 9 hours screen time on stock if I kept gameplay out of the equation. So no I'm not saying bullish*t, I'm saying my results. Just because yours differ and you buy into the "custom is always better" doesn't make MY findings on MY device any less true. Can custom be better? Sure, but it's not fact that it is.
And you say you've only had your 7 5 days, definitely NOT enough time to get real results. Especially since you spent 3 days on stock and less than that on Franco your results obviously aren't same usage scenarios.
Clarification: same usage means about same amount of use in same timeframe doing same activity. Which 6½ hours usage over 3 days is not the same as 9 hours in less than 2.

You wrong
Stock kernel frequecy with 4 cores enable
No UV because Franco R42 not working
No heavy games you are correct.

I hate to say omg. .I really do....but o m g!!! You don't have an N7. ..how can you give advice about kernels since you've never used one for the n7. Go ahead tho....test one on your Samsung! Lol

---------- Post added at 07:18 PM ---------- Previous post was at 07:13 PM ----------
And 9 hours screen on is maybe possible doing nothing at all CPU heavy!!". Not what most people get doing normal things on their tab. Anyone can keep the screen awake doing nothing really and post a screen saying they got 9 hours. 4 to 6 seems to be the norm. ..no matter the kernel.
That's my story....thanks for enjoying it!

All have kind of poor battery life
The thread for the baseband_xmm_power wakelock is there for a reason. And if I use my phone the battery sometimes loose like 10 percent in 10 min and then the other day it just gets along with 5 percent per hour the battery life on our device seems inconsistent as hell!

I think the best start point is to root your phone and then you're be able to do a lot stuff to your phone like flashing some good mod and/or installing any app like greenify or something like that. disable or remove any app/ process you dont need, change cpu govenor. disable wifi, bluetooth, gps when you're not need them.
and this last one is the best possible way....do not touch your phone.
