What's the best kernel wen on energy rom Aug 6 for best battery life
Sent from my HTC_Amaze_4G using xda premium
I'm runniing the same ROM as you, and use Faux's latest kernel. I'm getting great battery life with this kernel

NRG Stock Look with Stock Kernel. I like it because my second core actually goes to sleep when its not needed instead of idleing at 192 all the time. No crashes and I average 12-18 hrs with about 2.5-3 hrs of screen time. I carry a spare battery if I use my phone heavy.
Waiting for CM10 to he fully stable so that'll he my daily when it is.

Faux kernel let's the second core sleep too. Battery seems about the same as what you say the stick kernel provides, but I get much better antutu scores with faux, so there must be a performance gain without sacrificing battery.

for all of you rom tester..
Which rom so far has the best battery life in your experience?
I only have tested Void e and mik_os and I must say both are comparable.
I know other people will say different. I just want to hear from all of you custom rom flasher
so Which rom so far has the best battery life in your experience?
Thank you
Megatron with mik-os touch screen fix has good battery. Turn off background data in settings it helps..

I'm currently using LOL v1.42 and i'm pretty satisfied with battery life compared to overall performance. Today i'll flash OpenOptimus 0.072 for long run testing and see how that goes too.
I must say mik CM7 is really fast to charge... I can get a full battery in 1 - 2 hrs I think.
with mik CM7. I can take it off the charger at 7:30 AM and by the time I am home from work (at 6PM) I still have 40% - 50% battery left depending on the usage (low to moderate use). so about 10.5 Hrs of use 60% batt use.. about 5.7% per hour ..
I am using andy572 rom now and will report later
I use stock ROM (v10c fw) with mik_os fix, but don't really feel the battery is better.
What the title says.

all roms are gonna be similar in terms of battery life. Battery life really depends on what measures you take to reduce idle usage.
-download "green power / premium" and set it to turn off data while the screen is off
-keep wi-fi, btooth and gps off when you're not using them
-use "setcpu" and create a profile for when the screen is off, limiting processor load
-download "battery calibration" and charge phone to 100%. Use the app.
I do all these things (I use battery calibration after flashing every new rom / kernel/ ect) and on CM7 with a 1.3ghz OC, I got 18 hours of battery life with high usage. I've only used 5% of my battery in 4 hours with little use (mostly idle)
I've tried pretty much every ROM. The one I got the best battery life out of was pi crust 0.7. I'm currently on Aura 1.1.3.8 bloat with the stock att kernel and battery life isn't horrible, but nowhere near as good as pi crust.
Sent from my MB860 using xda premium
+1 on πcrust 0.7 I can can 30hours + on a single charge with moderate use. Over Clocked 1.1hghz and Under volted slightly.
Yeah, I used to be on Picrust and the battery life was really good. I got tired of the stock experience though so I installed Alien w/ theme. The ROM is really good, but the battery life is not consistent. Sometimes it's as good as PiCrust and other times it barely gets through the night.
if you do the things I told you to, the alien rom will get much better battery life. I used to be on alien 4 and got 30+ hours on a full charge
Ninja SpeedFreak gives me by far the best battery life over anything else. 40-50hours. Tried Alien, RedPill, Aura Debloat, Aura Accounts, PiCrust, Froyo stock, GB stock (Bell). Nothing but SpeedFreak will consistently get me more than 20 hours.
So, over the past few days I've been noticing a few problems with my phone, all of which have to do with the battery. After installing fauxes OC 1.3ghz kernel I noticed a drop in usages before the phone died, that's a given. So i flashed his enhanced 1ghz kernel instead, but still notice bad battery drops when im using it. It doesn't drop 40% over night or anything, only about 6%. But, if i turn the phone off and back on the % jumps up. Sometimes 20%. Is there anything wrong with the battery, or the phone?
Try calibrating the battery.
i haven't doe that since my first phone. How would i go about doing that.

Also, with faux's kernels check your CPU clocking with setCPU, or something similar. Somtimes it will lock at the max clock speed which will contribute to quick battery drain. I'm on his stock enhanced and getting close to 2 days with moderate use.
How do you get two days of battery?! Thar's intense! I haven't been able to get past the 15 or 16 hours with the stock kernel, neither with faux's stock enhanced! Do you usually drop your cpu speed while it's in your pocket or something? Or do I have a bad battery? Because I've been really concerned about this battery not lasting the monster time it is supposed to last...

I have uv and profiles set up in setCPU. I'm actually a little amazed by how good it's been since re-installing all of my mods (went back to stock recovery due to some issues).
If you're experience battery jumps then install the fix noted in the calibration instructions. Most likely you're battery isn't charging to full capacity, so that coupled with the improperly reported stats make it seem much worse than it is. The process is a bit time consuming, but it did work for me.
Little confused with my battery and SetCPU sitll

Well I have Alien #4 custom rom and it actually has the battery fix so it shows the 1% increase/decrease and I recently did a battery calibration by waiting til it got to 100% with an app that deletes the battery stats as if you would do with recovery mode. I also have CWM recovery and everything doing fine there, my kernel is now Faux's 1.3GHz but limited with SetCPU to 1GHz, and I don't know if it'll get me a better battery life just that kernel. What do you mean by uv? And I have profiles set for when the screen is off and when its charging but nothing else apart from the 1GHz setting. Is it normal that I only have 2 scaling options? Powersave and performace?
Thank you. I will be trying this tomorrow when I have the huge amount of time needed to complete this. And uv means under volt.

Thanks to you! I really appreciate it. I will be waiting for your response and maybe you could tell me if it lasts longer with the 1.3GHz ir the 1GHz. Thanks!!

So I took the plunge and unlocked my bootloader, and flashed the latest weekly of CM7. I love it so far, very responsive and quick.
I decided to flash the latest Faux123 kernel (CM7 Unified). After getting great quadrant scores, I was happy. I have a custom kernel on my Transformer TF-101 as well.
Here's my issue:
I get about 3 hours of battery life.
I clocked the kernel to max at 1.2ghz, and I even scaled the governor to powersave. (Using Rom Toolbox, min/max in SetCPU).
I have not undervolted anything at all.
My phone idle seems to shoot up to 40-50% most of the time, and SetCPU says that my phone spends most of it's time at 1ghz+. My TF would pretty much fall asleep at 216mhz, but that's a different device.
Is there something I'm missing?
This was a clean flash, and I always have plenty of free ram. I don't seem to have any wakelocks longer than 10 mins (alarm manager) either.
Oh, and my battery has been properly calibrated.
The stock kernel gave me great life (30+ hours). I expected a little loss, but not this bad after flashing.
Help!
Try a newer kernel. Governors don't work properly with our tegras. A newer kernel should have that disabled and more power save options.

What kernel do you suggest? Ive been out of the atrix scene for a good bit now lol.
My issues with battery life disappeared after installing jokersax's cm9 beta along with faux's kernel for cm9
Also be sure your battery isnt old and calibrate it(guides on main atrix forum)
Can I use a cm9 kernel on cm7? I don't really want to take the ICS route until it's developed a bit more.
My battery has been properly calibrated, though it still doesn't always hit 100%. I have no idea why either.

I woldnt try that.. About cm9, even though its beta, its pretty usable right now, most stuff works fine, you can always go back id it doesnt work.. I didnt went back bcuz battery is most important for me
Hmm, what about kholk or clemsyn's kernels?

I've stuck with fauxs. I think I'm using version 23. I'm not using the lastest one as it makes one of my apps buggy and I don't like how my CPU jumps around when idle. He is currently working on those bugs, but they are hard to correct. Lots of other people are using it though with good results. I also stay with the 1.0ghz versions. Overclocks are nice but I don't need them and perfer the extra battery life.

So after a night's recharge, it seems to be working a little better.
CPU Spy says that it's in deep sleep most of the time.
Turns out I had SetCPU, Rom Toolbox, and CM7's settings regulating the clock speed. I uninstalled SetCPU, turned off Rom Toolbox, and let CM7 take care of it.
Life isn't as great as I expected, but its an improvement. The processor still does "jump around", but I expect that to be fixed at some point.
I considered clemsyn's kernel, but I don't want to risk not having an "elite tegra" and blow up my phone.
I really like the .24 1.3ghz Faux kernel. With SetCpu I change between 1.2OC (using lapdock) and 1.1OC (rest of time).
Battery life is equivalent to stock kernel. (I put it on charge when I go to bed and take it off early in the am). It usually has 50% left after streaming music to and from work/Endomondo using gps to track 45 minute workout, all my widgets (news and weather) and a few phone calls.
Phone stays much cooler.
Quadrant standard vs my wife's Atrix (fully stock) with the kernel at 1.1 is 30% better.
Stock ROM; not CM7 however.
I just looked at a days logs. It says that my phone spends 3+ hours in both 1.2ghz and 800mhz, and about 9 hours in deep sleep.
I haven't used my phone much today (40m of display time), and it already got to 15% between 9am and 6pm.
I can't seem to find what's keeping it up either, no obscene wakelocks.
Just out of curious, how is your tf201's battery life? just want to see how each different rom works with the battery life.
by replying, could you please provide the follow info?
ROM+version:
Kernel:
CPU governor:
upper/lower cpu freq limit:
battery duration: discharging time + screen time
if possible, attach a battery discharging chart would be nice.
Thank you
Edit:
here is my own observations:
ROM+version: CM10 (no cherry pick) + flash very update when it is released
Kernel: default
CPU governor: On Demand
upper/lower cpu freq limit: 102 / 1600 MHz
battery duration: discharging time + screen time :
I have a total of 7.5+ hours of continuous online streaming videos
In daily use: 3 days of discharging with 5+ hrs of screen time (GPS: on, WIFI: never on when sleep, Sync: on)
Re Battery Life
This is a big one for me...
I've had my prime for about 4 weeks and have had a new rom every week...
The stock rom it came with .28 did have lags and generally seam not so smooth.
Battery life seamed quite good...
So unlocked installed TWRP and on to a better OS
First was AndroWook 2.1.
Battery was quite good Tried a number of variations but would still get screen tearing on the left hand side
Tried --[ROM] 7/5/12 Prime w/ Sense Appeal 9.4.2.28 Beats,Tweaked-- next
And yes it did seem more stable and had great battery life but the visuals were too over the top for me and some panels had white on grey and were a little challenging to decipher
Gave CM9 RC2 a go next... Love CM9 been running it on my SG2 since Jan CM7 before that... Love their work...
Installed it on the prime and had the wifi reboot issue where as soon as the wifi goes on or off it soft boots again and again and again... Ran it with wifi off and got very good battery life for a couple of nights but i really need wifi...
Ran Aokp next.. Love this.. Lots of interface tweaks and customisations. very stable very responsive probably the best rom I've tried but the battery life was woeful.../ Cut my battery life if half... 8 to 10 hours at most... less with wifi...
So now a month later I've come back to AndoWook and a stock kernel, cause i need stability and long battery life
Will probably settle on this for awhile till CM10 or AOKP JB gets outa Alpha and into Betta
All installs were with the default kernel image and default settings. Except AOKP there i used the conservative governor
Stock ROM .28
MODD:
1. build.prop TWEAK
2. ATP TWEAK v7
---- sio
---- tune.sh max
3. Overclock on 1.4GHz screen on / 1.0GHz screen off (interactive)
---- I make some profiles
4. RAM all the time on 500-700 mb
Autokill
With this my battery life is perfect! I never have a problem with AAaaaaaAAAAaaa i dont have any more battery! =D

Hard to say exactly because I have it in the keyboard dock a lot. At work, the keyboard dock sits on my desk and I put the prime in it whenever it is not in use. With moderate usage throughout the work day and then heavier usage in the evenings, by the time I'm done for the day I have often drained the dock battery down near 0% but the Prime itself is usually around 60%. So I wonder if I didn't have the dock, would I run out of juice on the prime? It's unclear though because at work I use a lot of USB accessories hooked up to the dock which may be responsible for the drain on its battery. I have a USB wired Ethernet stick that seems to really drain the dock battery - so its kind of hard to tell.
Given the usage above though, if I start out the day with a full charge on both dock and prime, it gets me through the entire day and up until bedtime without another charge - even if I watch a movie on it in the hotel room at night.
This is completely stock except rooted and unused apps frozen with Titanium backup.
Oh, and PS: This is running in balance mode all the time.
