[Q] Maximising battery life - Galaxy Note II Q&A, Help & Troubleshooting

Using rooted Stock ROM. I havent changed anything regarding the Kernal (as far as I know). I use pegasusq governor, sliders at 200Mhz to 1400Mhz. I/O scheduler at cfq (have no idea what it does so have never changed it!). Use Greenify on all shopping apps, games, and alot of utilitys I only need to use from time to time. Keep my screen brightness below 35%ish always, keep wifi and data connections off unless I need them. Have uninstalled or atleast frozen all the bloatware n apps I dont need or plan to use anytime soon. Clear the memory atleast twice a day.
The battery can fully charge from under 5% to full in around 1 hour! But is there anything I can do to extend the battery life even further?
Thanks.

Any reason why? cant see how this would help, but I'm clearly no expert! Had a search around for an explanation but all I seem to find is people making similar suggestions. Id prefer to keep the performance up at the sacrifice of a tiny amount of battery life. Perhaps a link to a thread I can read up on this?

I don't have the right explanation for this but basically, RAM optimizers or when you clear RAM, what happens is you DO clear them but they cache up again afterwards.
Use the recent apps and just clear those.
I'm not dropping any hours screen-on time I get because I use a ZeroLemon battery.

battery drain and Snap with CM6?

CM6 is definitely great, I think without question it is a vast improvement.
The only issue I have is my battery life is ABSOLUTELY HORRIBLE. Could be the worst battery life I've had with any phone. But maybe that's just the EVO, with it's big screen and speedy processor. I underclock to 384 mhz sometimes but then the thing slows down and even freezes. I have 3 different batteries and they all perform about the same (not good.) Before I had a partial wake issue but that's gone, and battery life still stinks. I've also tried calibrating but nothing really seems to make it better.
I hear the snap thing is good for battery life but I everytime I open that thread I get a headache. I love this phone and am obsessed wtih it but that thread is a bit much even for me!
Can anyone give me a quick and dirty explaination of what snap is / how to use snap? Which kernel to flash? Some day I hope to digest that mammoth of a thread, but right now I'm too busy reading texts for college and Just want better battery life.
Thanks!
Download app System Panel. Will help show you what is eating up your battery/resources.
Then, download app Juice Defender. Worth it to get the paid version. Its like 3 bucks IIRC. This will help you get more battery life out of your phone.

Yeah, I tried System Panel but the things eating my battery were mostly system things, like Browser. I guess I could give it another go.
Why are Juice Defender reviews so bad? I've considered it before also, maybe will try playing with it again
snap 8.2 is the current release. you can try any of the kernels, but i would avoid the 7.0/7.1 SD Card implementations since that technology has been put on the back burner for a bit.
Snap allows you to you Overclock and Undervolt (aka: UV).
Overclocking of course is for speed and Undervolting may save battery.
all EVOs are not created equal. some like undervolting some do not. so snap is available in multiple flavors. each with a different UV floor. the lower the floor the more potential battery saving..but also the more chance for a random reboot or wifi/gps acting funny. remember UV retards the amount of power so things can act goofy. the different UV floors are 800mv - 925mv. for example...i use the 8.2_900 because it works well with my EVO. the 8.2_800 booted great but after a while started rebooting itself. 8.2_850 just hung at bootup. the 8.1 kernels didn't work for me at all. 7.3b1 was great.
HAVs is adaptive..so don't get stressed if your device fails to boot properly the first time. wipe the cache/dalvik and try again.
so download a few of the 8.2 kernels.
make your nandroid
begin trial and error (I'd suggest starting at 800, 850 then 900 to get a feel)
don't be afraid to wipe the Cache and Dalvik multiple times.
don't worry about the whole thread. just grab the last few pages and read the OP. then feel free to ask.
i also recommend setCPU. you can find some threads for SetCPU configurations to help. BUT....make sure SetCPU is disabled when flashing the new kernel. once you get a working kernel you can enable SetCPU...but during testing phase it will give you gray hair.
jmxp69 said:
Just a few quick thoughts on voltages/freqs after seeing a handful of discussion in the thread:
1) Every 8.2 kernel has voltages lower than stock. The default stock voltage @ 245 is something around 1050.
2) No real effort is made to UV at the top end. It's a little lower, but the objective at the highest CPU frequency is not to UV. Most of the benefit of UV comes at the low end of the scale when your phone is idle (most of the time). Less voltage = less draw.
3) nHAVS scales voltage at each step. There is a min.max voltage at every cpu frequency. This range is fairly small--50-75mv, but it enables HAVS to decide based on feedback from the CPU which one to apply. And the max at each step is lower than stock. So no matter how you slice it, even if you're running 925, you are undervolted. This becomes a question of how undervolted.
4) OC is not about undervolting, it's about overclocking. The differences is voltage vs. frequency. OC means we're increasing the CPU frequency beyond stock which is 998mhz in the case of Evo. If you move your SetCPU slider beyond 998mhz, you're overclocking.
The objective of overclocking is speed. The objective of undervolting is battery savings. Snap gives you both. We overclock when we increase the fequency with SetCPU. We undervolt automatically via nHAVS. As of this writing, UV is handled in the kernel, it happens most at the bottom end of the frequency scale.
I hope this helps clear up some of the questions. Great conversation by the way.

GREAT EXPLANATION Dragin!!!
and also, to the OP.... dont forget, if you do go with setcpu, do NOT 'set on boot' mmmmkay??? lol
Thank you Dragin!!!
That helps a lot! So once you have Snap setup at what you feel is "good" does your phone seem to perform as well as before you had it undervolted? Man, sounds like a pretty involved process - maybe I better wait until I can really sit down and play with it.

Do you mean for the first flash? Or every time you boot your phone?
If not set on boot, it means you have to start SetCPU manually after each boot. Doesn't seem right

Regarding Juice:
I didn't really read too much into the reviews for this particular app. It works. I was having battery issues. Downloaded Juice, got the settings somewhat right to my liking and so far no complaints. Unplugged my phone from charger this morning at roughly 9am, been using it moderately all day, and as of right now at 12:50am, I am at 29%.
Bad reviews or not, I can attest to it working and making a difference in battery life.

Do you know what in particular Juice is doing to give you better battery life? like what does Turn off certain things based on conditions or?
That is some good battery life.
Correct.
You can set conditions to do certain things. Such as disable data/3g/wifi while screen is off. Also if you need data synced you can set a condition to enable data wifi or 3g for X minutes every X minutes/hours.
I am not affiliated with the dev in anyway but it def made a difference and was worth the price for it.

Meh... see I really don't want to do those things. I can turn off data sync myself and just have gmail forward me a text message when I have an email. I just was hoping there was a way to get decent battery life without going back to the days of Winmo
I absolutely adore CM6, but I'm really starting to think that it is not battery friendly. Last night my battery went from full to 25% in 8 hours. I had nothing running, my partial wake was fine, and Android system took up 60%+. I really don't feel like doing another wipe, but it looks like I may have to. Just want it to work right at this point.
Again, I truly love CM6, the open source concept, the transparency, the whole clean idea of it, but there is something seriously wrong with the battery life (at least in every install I have tried)

i agree with you. but i also feel that CM6 is on par with the Official HTC/Sprint ROM when it comes to battery life expectancy. however, after i put on the snap kernel and copied someones setcpu config....i got 26+hrs of 'use it as i wish' time + still had about an hour of in-pocket time left. i was hooked. i bet you an imaginary dollar the same will happen for you.
as for finding your EVOs kernel made in heaven...
it's not too bad so long as you have some time. but if you are time strapped, need your phone in 20min and don't read the OP... you will curse and swear. expect to get hung up at the HTC splashscreen a few times and it will bootloop on you before your done. <I'd suggest just leaving your battery cover off until you are done muckn about for that session>
klick may be easier for the some end users because of fewer selections. I've never used his kernels. if i try them, i'll prolly wait till he's put out a few AOSP versions...to work out any bugs.
oh yeah...one odd thing, it seems that sometimes folks flash a incompatible kernel it gets 'stuck'. after that 'bad flash' they are unable to flash any kernel until after they have nandroided back and rebooted...then they can flash again. i had this happen twice....i was unable to get a known good kernel to load until after i restored from backup. /shrug
oh....try this. download the snap7.5_925 kernel. if it runs smooth. call it a day and you should be pretty happy with that until the new versions come out. yeah, if you got one of the _800 kernels running you may pull an extra 30-45min of time...but that requires a level of geekdom that not everyone has.

Yeah dragin, don't hog those sweet settings! I'm enjoying Snap 7.6 and it seems to be helping out my battery life a bit, but I'd love to see your SetCPU details.
I've found that the issue for me is bluetooth. If I have it on constantly my battery will drain 10-15% per hour. With bluetooth off it's only draining 1%-2% per hour.
Seems like the bluetooth needs work on CM6 in order to have the efficiency that the other ROMs i've tried (Fresh and EViO) have. Nonetheless, I'm sticking with CM6 and just use the bluetooth when necessary.
I have the same issue with bluetooth on CM 6.0.0. I am running the stock kernel that comes with cyanogenmod, so this is definitely not a snap issue. There was a bug submitted about a month ago:
code.google.com/p/cyanogenmod/issues/detail?id=2136
I *really* hope this can get fixed for the 6.1 release, but it is currently listed with a low priority. I really love CM6, but basically making bluetooth unusable for more than a few hours really makes me struggle with the using this rom.
Why not the 7.6 with turbo...just wonderin

It work a little ..but like the guy said save ur cash...

I use sense roms and i see a big enough difference with JD Ultimate for the few bucks it costs..i get close to double my regular battery usage with it..there is ways to get it without paying if u are into that kind of stuff
i'd try normal juicedefender first. if you like it, then review what features you will get from ultimate. if you think it's worth it, then buy on in. if not, then don't.
btw, in my experiance, letting it toggle my 4g actually lost me battery.
My experience it was ok. I got it for the sense 2.1 rom due to the brightness issues. I had to unistall it because it was making my connectivity act up. My data wouldn't start back up on wake sometimes. Overall it wasn't saving me a dramatic amount either.
In all fairness I didn't customize it. Just used normal or aggressive default.

SetCPU
If you're really gonna spend some money on an app SetCPU is the way to go for battery life (Assuming you're rooted). This way you have a customizable governor on your processor and you can tell it how fast to run. Unless you've already done this in which case sorry. I get at least a good two days out of my battery on almost all the roms I run and I flash a lot, Letting it die completely when the screen is off does a tremendous job & really you don't need it to run over 700 mhz for most things. Give it a try, the trick is setting the profiles. Use on demand for your scaling then set accordingly, keep in mind you need to set the most important profiles such as temperature and screen off as your 100 or 99 level profiles. You'll get the hang of it, but as I said if you already use it then this was a giant waste of typing
P.S. if running the Stock HTC Kernel you have to disable perflock in order for the profiles to work. Main tab, menu, perflock disabler.

First of all, the super awesome setcpu developer posted it on the forum for free, so you don't really need to buy from market. Second, the smart ass governer can do this all automatically. Finally, juice defender still works better for me.

I use Tasker from the Market, creating profiles such as turning off data when screen is off and data on when screen is on (doesn't affect voice calls or SMS/MMS). Also, I use Autokiller Memory Manager (not a task killer). I can get from 17 hours on normal use to 31 hours with light to moderate use. As I write this, I'm at 88% battery left after 5 hours off the charger.

[Q] How can I get longer battery life [suggestions about Roms, Custom Kernels, etc]

Hi guys!
This One X is very performing smartphone, games are really pretty... But I can stand that battery problem! I've tried so many rom, using setcpu for ondemand governor of the Tegra3... But I still not have so many battery life!
Can you guys suggest how rom, kernel or something else can save my battery?
Generic suggestions about this problem... Now I'm using Jdroid exodized 3.0.3 with bricked kernel v0.2, but battery is so draining... 63 % of battery with 1.37 hours of screen.. 4 h 22 min on it! =(
Hi!
I see a lot of people complaining about battery life, but if you take a look around you'll find the thread where people posted their battery usage. Me - I'm using rooted OneX running the stock ROM and am more than satisfied as far as battery life goes. I do 15 hours with ease. If I try to save it it usually lasts for more than 24 hours. Maybe you could try stock rom + root ... maybe a little underclock? I've been hearing underclock is quite the juice saver.
Hi,
I am the same I have tried custom Rom's but they claim to improve battery life but they just move the tegra 3 powersaving driver into the correct place!
I have a unlocked O2 HTC One X with O2 Rom and flashed battery fix and rooted the device!
Using this thread: http://forum.xda-developers.com/showthread.php?t=1597227
I have managed to setup a shortcut using widgets on the screen to select how many cores I want to use. I find that using one core clocked at 1.5GHz is fast enough and I don't have much lag! This has helped my battery massively! This is because O2 still haven't pushed through the HTC updates yet!
And also using this thread: http://forum.xda-developers.com/showthread.php?t=1630200
I flashed this using CMW and this has also helped.
I also find disabling some stock apps using App Managment in Settings, also using CPU spy from the Play Store and Battery Usage in settings. I can find the apps that use the most CPU power then uninstall or limit their usage (maybe using the internet instead of a dedicated app) this then has the phone stay in Deep Sleep for longer. I can easily get through 24hrs without having to try to save battery at all! I sometimes have almost got two days without charging!
Another tip is in the Usage app you can Restrict Background data over the network although when you connect to your WiFi it enables it again. Although it is meant to help save your Data it can also help your Battery Life.
Hope this helps!
Steven
Thanks for the answer!
I noticed that, in this Rom that I'm trying, I've the Screen that consume a lot of battery, even in the lowest brightness mode. Not using WiFi, 3g data, autosync, nothing, only a lot of text message received and sent. I think that this S-LCD2 consume a lot of battery or maybe the software of HTC, this time, is a loot poor of balance with this expensive hardware.
Do you think I can improve battery life with the tips that you said? I'm using this ROM right now http://forum.xda-developers.com/showthread.php?t=1597778.
Setting CPU to ondemand governor 304 mhz min and 1.5 ghz doesn't help me? I must disable some cores? I can give it a try, hope that this tips can be made in this AOSP Senseless Rom.

I'm asking myself [ and you ] if this screen consume really a lot amount of battery... Or there is some problem with my one x... Reaching the 3+ hours screen on is a good result, but in a 15 h battery day life, I hope... Maybe I can reach disabling a couple of processors
Don't worry about the screen, it will always take a lot of power whatever you do! It isn't worth messing with it.
You don't need to mess with the CPU although personally it does make a diffrence to the battery, I don't notice it too unless I am gaming!
Maybe an app is preventing your phone from going to deep sleep whilst the screen is off
Try using this app: https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en
If it says that your phone hasn't been in deep sleep, We need to try and find the culprit. Once you have done this maybe post back and I might be able to help you sort this out! It took me a while as I had this problem but it was definatly worth the effort!
Try looking in battery in the settings and see if there are any apps that are using a lot of power (maybe take a screen shot) and also try in Data Usage, there maybe apps using the Internet whilst you aren't using the phone. This also wastes the battery. If you restrict background usage (only on certain apps) it will only use the Internet in the background whilst you are connected to wifi only. Facebook is a good example!
Hope this helps
Steven
If you don't understand anything please say, I know my explanations are awful but I will try my best! I think I have changed everything here to fit your rom!
The rom itself although you or the developer know this but the overall system could be causing a problem! (just a theory!)

You're too fine with me steven, thanks!
I've downloaded Cpu Spy and it says that my one x has been in deep sleep for 70 % of time, so there is no problem with some apps doing something during screen off. My problem is that when I'm using all 4 cores, without internet via wifi or 3g, without autosync, nothing at all, and screen at lowest brightness, there is still a drastic battery drain while I'm using only Message app a lot. I don't wanna think that my HOX have a fault battery, but how can I test and prove it ? I don't know if there is a program, app or test for doing this thing.
Now I'm with that ROM Senseless AOSP ICS, I will try next charge with two cores actives only and view how much I can stay with that SetCpu settings. I'm using this settings: 101% Battery <, CPU Max 1Ghz to 51Mhz and priority 100, governor ondemand ; screen off, CPU Max 1Ghz to 200 mhz and priority 100, governor ondemand. I'll give you the result soon.
you need to give it time to settle the battery mate. i manage to go a day or two and have like 3 hours screen on time and that is with everything on. if you need any help send me a PM mate and i see what i can do to help you. and i would not use SetCpu for now i am using No-Frills. And switch from ondemand to Interactive. and that is with 1.5Ghz as max and 100mhz mininum

I agree that you should not use set CPU although you are best using ondemand as that is only using the amount of power you need, interactive keeps the speed high to increase the overall speed. (not good for battery life) also maybe, my mothers Samsung Galaxy S2 had battery problems and she got 6hrs of battery out of her phone at max, she always carried her charger around.
I calibrated the battery without using any software, I just fully charged the device and left video/audio/maps on to get rid of the battery as fast as I could and then fully charged the device. All I am trying to say is give this a shot (I did this when I first got my phone) she now gets on average 2days battery life! I know that it can take ages but it is defiantly worth the effort!
Hope this helps

Also, how do you find that ROM it looks great. I think I might try it!

if it is me you are asking about the rom mate it is really good highly recommend it
I don't know guys... My phone without two cores seems to have more battery with setcpu on demand declocked at 1 ghz... But I mean, this screen... Lowest brightness, consumes a lot... Wanna try some other roms, like X Touch Xtreme or InsertCoin =)

go into settings-sound and untick the lockscreen sounds and untick the touch keypad sounds to. come out and reboot the phone and charge...let me know if you have those two options ticked

What is this meant to do!!
And thanks, I am going to try that ROM now, just backing up mine now!

What, The Senseless I've meant? Tell me what you think!
P.s. Seems that the Leedroid 6 Rom with Franco kernel it's a good couple for battery life. Read this one, post #33 : http://forum.xda-developers.com/showthread.php?t=1648687&page=4
In this Rom, The Jdroid Exodized, I can't try the HTC Battery Test. When I'm trying new one Rom with sense, I will keep in mind to do that.
In the mean time post your suggestions about other roms or other tips for this tooooo much powerful phone =)

it is meant to stop the audioout_3 wakelock from draining battery while the screen is off. install betterbatterystats. leave all your stuff in sounds ticked..then charge your battery to the full and seee what i mean once you start testing the battery

Sorry goku, I want to ask you if you reached the point of 3 hours screen on with everything on, with a day or two with battery! I read that you're using leedroid v 6 with bricked kernel v 0.3, how is battery life with this software? Thanks for the answer!

Recommend A Rom? Need To Save Battery

Hi,
I just got my HTC One X and I love it. The only downside to it so far is after leaving it on charge overnight im lucky if I get 5-6hrs out of it.
Im on the default OS and ive only installed some apps but im pretty much in the dark where to start.
Can anyone recommend the best rom to use or even just good apps or ways to make my battery life extend?
Thanks and again sorry if this is a noob question.
Have you updated your device with all the official updates? Have you disabled fast-boot, auto-brightness, satellite-GPS and all other wireless options that you don't need and opted for a 30-40% luminance rating (screen remains legible) in Settings? The operating time you get, as stated of 5-6 hrs seems pretty low. I get at least double that with intensive usage, and I mean it, THD Games! Keep in mind however that the screen of HTC ONE X, REALLY, IS the most power-demanding component of our smartphone and there isn't much that can be done about it.
As to your question, Villain rom is considered by many to be battery-friendly although pretty basic. In addition and if you have a rooted/unlocked device (I still haven't rooted mine because I'm perfectly satisfied with it for now), you can also give a try to the SetCore app that can be found i the Apps section of the HOX forum and as its name implied it allows you to control and deactivate cores at will. Also try out the well-known SetCPU app to underclock the processor and get more life from it.
Although, if you've purchased your phone recently, you may simply have to charge some more to condition the battery and then it will get to normal levels, of ~12-15hrs of serious usage.
first of all you do not need a rom that is based on battery life..all roms are the same with just few different modifications to it. choose a rom that YOU like and not based on what other people tell you. Then you can do a few things to get better battery life. as the poster above me stated you can do what he mentioned..but i still with autosync on, GPS on and autobrightness i can manage to get over 3hrs screen on time and over a day and a half battery life. Go into settings and sound and untick touch keypad sounds and lockscreen sound and dialpad sounds...come out and reboot the phone..you might think why but trust me that causes drainage to the battery and keeps the phone wake when the screen is off. second if you use twitter and facebook i would suggest to use them only when you log in..do not have it on in the background. if you still need more help PM if you like
but search for Touch Xtreme rom by Smarberg...that is a good rom based on battery more than anything else.

Im sure all the official updates are done. I use wifi in house and 3g when outdoors. Ive got bluetooth and gps disabled and as of now my screen is off automatic. Ill keep charging like you say to condition the battery but can you overcharge it?
I'm on stock and my battery seems to be OK.
The multitasking on another hand is shockingly bad.
Please someone give me aokp or cm9

I fixed multitasking with an init.d script that lowers the low memory killer values. All the apps stay in memory now without closing... like they are supposed to.
Some say HTC set the values so high to save battery, but that is crap. No power is used when the app is held in memory, infact less is used as the apps aren't constantly being opened closed and reloaded. I think they just messed up.

[Q] AOKP Ktoonsez + KT747 = ?

Hey I want to know how KT747 kernel works with AOKP Ktoonsez and Task650. From what I hear its pretty good. My main concern is battery life. I heard some people get around 5 hours of onscreen time which is incredible. If you are running these two together, what are good settings for good battery life? I'm using KT747 with CM10 M2 and Ktoonservative/noop but battery life is kinda bad. Thanks
I'm running that setup and although i can't really compare my battery stats to your as i have a 4400mah battery, i can say that for my phone atleast the battery life is superb. I actually just plugged it in after 67 hours, with about 7 hours screen on time. Obviously this isn't going to happen on a stock battery (mine came with a 2100mah), you could realistically expect a little less than half these numbers. I would suggest taking a look at this thread, which discusses overclocking and undervolting settings. I have posted pics of my personal undervolting settings (page 15, post 150), however your device may differ. I discuss why and my suggested method to finding the best value's for your device in the same thread, post 152 on page 16. Of course the discussion has many other opinions and suggestions as well so try them out until you find the one that works best for you. One thing i didn't mention is to disable the cpu settings in the settings>rom control>performance menu as it will conflict with the settings in ktweaker and can actually drain the battery much faster than normal.

Thanked*. Will take a look at the thread. Last time I undervolted I used some guys settings which were extremely wonky and cause a lot of mishaps. I'm still looking for good ones so I might try yours. Thanks.

Just tried it, it was a little to much so I bumped everything up a little bit. Seems fine now. Going to flash AOKP later today.
Thats actually how i got those settings, i used what someone said was stable on theirs. It wasn't, playing pretty much any game on my phone would cause a reboot in less than 5 minutes. I think i ended up about 20 mv higher on all steps than his settings. You just have to find what works for you phone.

Indeed. I have AOKP with Ktoonsez/sio and voltage a little higher than yours. Works fine, battery is good.
I have recently switched to the noop scheduler after an article i read which basically said there is no need for a scheduler using flash memory. All the other schedulers are designed for physical hard drives which have seek times, flash does not. Using these schedulers actually creates an artificial seek time, thereby wasting cpu clock cycles and burning precious energy in the process.

KT747/Cm10 m2
Hi,
I installed Cm10 m2, then ran it, rebooted, and installed kt747, cleared caches and fixed permissions, could not boot afterwards, Anyone else have this problem?

Hmm, I've never had that problem with KT. Make sure you have correct version, AOSP JB. I would recommend flashing CM10.0.0, the latest CM10 stable build.
