Ok so here are the tools I use
An automatic radio activation tool that will turn radios/wifi /gps OFF when screen is off - Juice Defender Ultimate is my choice
A CPU management tool - I use AnTuTu CPU Master but i hear that SetCPU is also very nice
Better Battery Stats
I Have setup Juice Defender (JD) to turn off my radios/wifi/bluetooth when the screen is off, to manage auto-synch, manage screen brightness but i DO NOT use it to manage CPU. I have also not setup any special App settings in JD, it just manages power consuming hardware (other than cpu)
My CPU tool (whichever you use) is used to setup profiles based on situations. Screen off, screen on, in call, etc.
There is never any reason for your CPU to be over 700mhz unless you are interacting with your phone. When you are on the phone 920 is all you will ever need. You can set the max above 1200 if you want or need the extra power but just remember that the cpu is always going to be a battery drain.
The #1 thing to remember is that if your not using your phone actively, it should be doing as close to nothing as possible.
Now I would love to hear from others on experiences and strategies or even critiques of my method. I know many will say that JD is not needed, bit i like not having to think about it.
I stick with Trickster Mod app for CPU/kernel settings. It's amazing. Also I never use Juice defender I use Tasker :thumbup:

Good idea starting this thread but I feel that you've opened up a can of worms
I've used JD before on my Dinc2 and I liked the fact that it can manage the radios but for me, I get a lot of emails and I like something on so I stopped using it. I did try some other apps like that but JD was my favorite by far!
Check out TricksterMOD from the app store it blows setcpu out of the water! It let's you do so much more and since I've found that I can't go back to anything else.
I usually don't undervolt, I feel like the kernel developers so a good job with their frequencies so I leave that alone lol but I have been recently checking out the governor settings to try and optimize a few things, that's a tricky topic lol

What ROM you guys running for best battery life? I seem to get the most from aosp based roms and not cm10 or aokp ones.
Im using XenonHD with Tinys kernel. I saw HORRIBLE battery life until i took action to tame it. now its much better

Mines close to stock on purpose but I don't mind people tuning it. What did you change that helped battery? There's bit much from a kernel perspective that will really help battery.
And this topic doesn't belong in development.

i guess it belongs in general but the idea was to get all the tidbits that we need together in one app specifically for our phones. like "The CDMA Galaxy nexus Super Battery saver app that does it all without all the stuff you dont need"
Just flash lean kernel and turn off mobile data when you're not using it. No need for these crazy battery saving apps. I get ~7 - 9 hours a day, easily.

Since radios are such a huge drain ...
I think my best move has been using an app called Profile. You can use it to turn off and on WIFI, Bluetooth and change the screen brightness at certain times on certain days. So at my usual time to go to work, WIFI gets shut off. At my usual time to get home, WIFI back on.
Also will change ringers, volumes and vibration on/off (always off uses battery).
24 hours no problem.
Costs a couple of bucks to get the time based control, but works for me.
Two tricks are using auto brightness and using WiFi whenever possible.
However, since I can't stand either of those options, using trickstermod to set max CPU speed while screen off, and setting color profile to morific typically helps my battery life.

Yah why would you need to lower CPU on sleep when we have deep idle?
I use CM10 nightlies, and the latest dev snapshots of Imo's leankernel. Min frequency 230mhz, max 1350mhz, interactivex governor with his tweaks and sio i/o scheduler.
I get ~24 hours battery with decent screen-on time, from just texting, about 20 minutes on the phone, and websurfing on full wifi service wherever I go (stays connected even when sleeping, and we have cross-campus wifi here). 3g service only, no LTE here yet. Bluetooth off. NO apps--many of the market "powersaving" apps will just wake the phone from sleep and cycle a few times to write to the log file (any app that keeps track of power consumption, and half of them don't even use the system tools). GPS is on, but it's never initialized more than 1-2x a day for random needs.
Getting a lightweight kernel is a good choice for battery life saving, and getting one that actually keeps up with android mainline is pretty key.
I think it's most helpful to post your total 'screen on' time and time since charge. If someone tells me they get 14 hours, that means nothing. I can get a full day 16 hours with roughly 2 hours of screen on time, without limiting my phone via turning off mobile data, syncing, or using a juice defender app that disables a lot of things.
That, to me, is not very good at all. I saw that the Nexus 4 is getting about 4.5 hours of screen on time with a full day of being on with everything syncing, etc being on. 4.5 is actually pretty bad also compared to other devices these days.
No matter what I try I usually only get about 2.5 hours of screen on time. I under clock to a max of 750 screen off at 280 undervolted to in each setting.
I've tried many many kernels with many roms
Screen on time doesnt mean much me to me because i use my phone for personal and business use, which means I get quite a few calls.
I use the stock 4.1.1 image, rooted with SuperSu and debloated a bit. Also use Faux kernel 23m-sr and his control app.
I roughly get about 2.5 hours screen on time with light calls and about 1.5 with heavy calls - my off charger time is pretty good though as it easily gets me thru the day. I bought another OEM standard battery and just keep one fully charged at all times so I can swap. Works well for me.
I also keep 4g on - why not when you can swap batteries.
does leaving gps on all the time if you're not running any location apps bother the battery at all?

No only when you use something requiring device GPS does it turn on. Most background stuff like Google Now uses tower fix so it's OK to leave it on.

Battery life is a pretty unique experience for everyone. Apps, ROM, kernel, signal, Wi-Fi time, brightness, etc. Won't say these type of threads are totally pointless but they are pretty close to it. Always good to share pointers on how to save a few minutes of juice though. Ultimately its a big screen and turning it off now and then is the best way to save but personally I leave all my services on because that's why I bought this thing and I keep a charger everywhere I go.

Hi all,
I've set some profiles in SetCPU but haven't noticed too much in battery life savings. I was wondering what others who are using CM 6.1 have been doing/would recommend. Should I get rid of the profiles and just have it set to on demand? Do I really need it at all with CM?
Many thanks!

How high are you overclocking?
What's your usage?
What's are your profiles?
Overclocking to 1401 on demand
I use power amp with scrobbing to last fm for probably an hour or two when not charging, while playing games that aren't to elaborate (boring stuff like sudoko) during my commute to/from work, which is probably my heaviest usage. I also do the same music set up while at work but I'm plugged in most of the time for that and volume is way down. Calls range from 30 min to an hour a day. Some intermittent web and video streaming while at home and on wifi. Typically only on wifi when at home, only when I need heavy data. Data sync is turned off when I'm not charging unless I want to sync.
I have profiles of 368/245 while sleeping, 75 priority; 738/245 when temp is 40.5 C, 60 Priority, 1401/245 when plugged and fully charged, 50; 368/245 when battery less than 10, 60; 806/245 when battery less than 40, 50 priority.
I'm thinking the fully charged one is probably redundant. Should I raise the priority on some of them?

I think I'm just using the cyogen mod kernel...but I'm new at this so I am a little clueless on that part. I did set higher priority on the temp and the screen off, got rid of the charging profile. I'm at 13% battery after about 15 hours, which isn't horrible but not the 30 hours some folks have been posting.
Sent from my HTC Vision using XDA App
had to dig back to find a good thread to post this on....
so I'm really leaning toward deciding that setcpu profiles do more harm than good in terms of battery. I had profiles set for temp, screen off, charging, battery below 30, and battery below 10. its pretty clear to me now that it wasn't helping my battery. and the only time I even had it overclocked was while charging.
next I'm going to just enable only a screen off profile, and see if having setcpu monitor for less profiles makes a difference. i'm not going to overclock at all. we'll see what happens.
btw I've had a rooted android phone since the G1 so its not like I don't have experience with setcpu. seems that setcpu affects different phones in different ways. so I'm still figuring out how it is on the G2.
anyone have any thoughts on this?
The screen off profile does not work.

really? I hadn't heard that. is this confirmed?
though, it never seemed to make all that much sense anyway, as I wouldn'y think there would be any reason for the cpu not to remain at a low freq with the screen off
The screen off profile works for me. I just set to "ondemand". Lately I've been using "cpu tuner" instead and have noticed better battery life then with set cpu. Plus with cpu tuner you get more profile options.

To be honest, not sure if its the case for you but profiles was the cause of my battery life drain. I took off all profiles and only kept screen off. Even since I did that I get about 24 hours + of battery.

I had a similar experience. The more profiles I had enabled, the faster my battery would drain.
I am using the same setup now and have great battery life. Even with heavy usage I can make it through the entire day without needing a charge.
Running On Demand 1209/245 and screen off 245/245.
Haha this was an old thread. I'm now on CM7 nightlies and would say that in my experience I've had the best battery life running no profiles whatsoever in setcpu. I only overclock to 1017 and it's been pretty snappy still. My experience in going higher than this on CM7 has lead to issues with wake, temperature and battery drain. I personally Have no need for more than 1017.

agreed. this setcpu stuff did not help at my device. nor did it work reliant.
i am managing 1day with heavy use and a full weekend with moderate use without any "tuning".
that is enough for me.
I used setcpu for awhile, but I have been much happier using cpu tuner and "power control".
My battery life is increased by 12 to 24hrs. The key for me is really using power control to manage the screen brightness and under clocking rather than overclocking. The only time I found overclocking usedful was when playing fifa10.
Good luck

All,
In case you haven't noticed, the battery life of the Nitro HD is kinda bad... Then, when you add ICS into the mix, it gets worse.
When i first flashed the Leaked ICS ROM, I noticed that I was only getting about 8 to 9 hours of battery life with very light use. So, I endeavored to find a way to extend that time without buying an expensive extended battery.
Here are my findings:
GPS
Settings > Location Services
Now we all like the convenience of being able to pull out our phone and find the nearest gas station or fine dining experience. But when you think about it, in our day to day lives, we don't need directions that much.
GPS and Location Services are huge data and energy hogs. If you have ever seen how much can go on in the background when it comes to Location Services, you would cringe. So, set up your GPS like the screenshot below and you will see a little battery life improvement and data usage go down.
Display Brightness
Settings > Display > Brightness
On my Nitro, the display uses up the most energy by far. So, it only makes sense to lower the brightness a bit to save power.
Developer Options
Settings > Developer Options
The Nitro has a powerful 1.5GHz CPU which uses a ton of energy when in heavy use. Some of you might say, "But Matt, I don't use that many apps that need the CPU." Well, it's not that you use them. It's that the ones you have used are likely still running. For example, even though I always use the 'Exit' menu item in Slacker Radio, it will always show up as a running process in Task Manager.
In the Developer Options, there are a few useful ways to fix this problem.
First, check the box next to 'Don't keep activities'. This will cause whatever app you are using to stop completely as soon as it is not on the screen anymore. This is useful if you have the habit of using the 'Home' button when you are done with apps.
Next, set the 'Background process limit' to something other than the standard limit. I have mine set to 4 processes. This will keep processes that are not tied to any specific app in check.
If you use a lot of apps and games that have to render video, it might be a good idea to check the 'Force GPU rendering' box. This will force apps such as games to use the slightly less powerful GPU in the Nitro for video. Thus letting your CPU relax a bit. I have also noticed that heat doesn't build up as much with this box checked.
Lastly, if you want to know about more of the processes that hang in the background that may cause performance issues, you can check the 'Show all ANRs' box. Personally, I found it annoying.
Power Saver
Settings > Power Saver
I was really excited for this feature but also very skeptical. But, I gave it a try anyway. What this feature does is when your battery level gets to a certain percent that you choose, it will turn off power consuming features and change some settings to use less power. I have mine set to engage at 20% battery life.
The tips I have seen say to check every box. But, because of my profession, I have to have 'Auto-sync' left on for emails and such.
With the settings below, I usually see the last 20% of battery last about 4 to 5 hours of medium use.
CPU Clock
*Requires Root*
Unlike all the tips above, this one will require you to root your Nitro.
As I said before, the 1.5GHz CPU uses a ton of power. When you think about it, unless you are playing games all the time or doing some kind of complex calculation as part of your Quantum Physics experiment on you phone, you really don't need all that power. So, what I did was underclocked the CPU to 1GHZ. This gives me the power I need to do what I do but with more efficient energy consumption.
I used SetCPU for this but there are a few other choices out there that do the job just as good.
As you can see from the screenshot below, I have set the max frequency to 1026MHz and the min frequency to 384MHz (I have since set min to 192MHz). I set the governor to 'conservative' based on this post: LINK. But, I think that any of them will help in different ways.
If you are curious, I'm also inserting a screenshot of my benchmarks after the underclock.
CPU Sleep (Suggested by rani9990)
*Requires Root*
XDA user rani9990 suggested an app called CPU Sleeper that, essentially, puts additional cores into an offline mode while the screen is off.
I can see how this would be advantageous because when your phone is in sleep mode, it really doesn't need all that extra power.
I have had it on my phone since i got up this morning and have noticed a significant jump in battery life already.
Results
Before these tips, I was getting about 8 to 9 hours of medium use on a charge.
After, I get roughly 15 to 20 hours of medium use. (It varies from day to day but hovers between 15 and 20.)
If anybody has any other tips, please let me know so I can add them to the list.
You should also tell people to get CPU sleeper (root) saves tons of battery life for me.
Also, disabling haptic feedback saves battery.

Sadly, battery life on this phone really sucks even with the optimizations. having compared both, I can say that the Nitro HD with optimizations and 3800 mAh Hyperion battery gets about the same battery life as a Galaxy Nexus on the stock ROM and stock battery.

Perhaps check your running processes. With these tweaks in place, I unplugged my Nitro at 7:45is this morning and right now, at 2:15pm, I have 79% battery left and I've made two 15 to 20 minute phone calls and rebooted about 6 times because of some testing I've been doing for another thread.
Also, the Nitro does have a faster CPU that would take more power than the Nexus.
I have done all of this, in addition to in Settings/Wireless & networks there's "more..." click that and theres "Mobile networks".. and the option for "Use only 2g networks" I'm using that for only texting while at work and doing pretty decent with battery life. since 5:45 to now 10AM texting all throughout that time I'm at 85% battery.

What I`ve noticed is that when I set Brightness to 100% I have 3...3,5 hours of wake working screen active time before battery exhausted. It's on ICS leak V18F. But if I set brightness to 30% or "auto" mode I got about 2....2,5max hours of screen active, it exhausts quicker
And secondly, on CM9 it helps me to check off "surface dithering" in 'performance' options. But on official ROMs we haven't this option available to tweak
I found that JuiceDefender has seriously saved me a whole lotta battery. Like seriously. I was getting 12 hours of medium to heavy usage before, and now i can hit 30 hours of medium usage. Then again, Data isn't turned on for me, I use the phone for Wifi and Calling.

For me keeping the wifi on (and thus connecting via wifi both at home and in the office) allows me to save battery..
To me it seems strange, because my old phone literally sucked battery while keeping wifi on, but on the nitro wifi consumes less than hsdpa data transfer.
I've added a link to my SetCPU Profiles file in the guide.
low antutu battery benchmark scores
Both stock and CM9 RC2 are disappointing: 250 and 328 respectively. I've applied the suggestions here and don't know if I'm doing something wrong.
I was rather happy with my phone with GB managed by Battery Defender from Infolife. I used to have 1,5 day with "Mostly Idle" usage. Now after upgrade to ICS I just got 10% down per hour on idle. So disappointed. I'll play with your settings a while. May be Battery Defender uninstall/reinstall can help too...
I've seen so many threads here and at The Verge that I just don't understand. I've been using Android devices now for about two years and I've NEVER had a problem with battery life being worse than my iPhones. I have a 3GS and the battery on it dies after about 8-10 hours of moderate use. Meanwhile, I'm at 12 hours on my SGS3 and 50% battery. I also have quite a lot of applications running in the background. Granted, today I have been low usage, but yesterday I was on the phone for hours and I still went 12 hours before the battery icon turned yellow. I haven't HAD to recharge before 12 hours for ages, even my Atrix went longer than that. I even have a screenshot from a few days ago where I went 14 hours and only dropped to 63%.
Are people just nuts or what is going on here?
People expect to play games at max brightness for hours and still get 12 hours battery life.
In with you, I use my phone constantly through out the day, I run my business from my phone, and routinely get 14+ hours per charge no problem. I just made a few tweaks, nothing big, and I'm good to go. This phone lasts noticeably longer than all my previous iPhones 3,3g and 4. Plus it charges twice as fast as those and never over heats... all my iPhones would get so hot that I couldn't charge them in the car with out testing then in an ac vent, and that's just from half an hour to an hour of talking... sgs3, I can talk for hours with no overheating, and it charges like a boss.

I am not sure what is going on. I don't have the best battery life I can get 10 to 12 hours moderate use. Steaming music, reading rss feeds, checking email, 2 to 3 hours screen on. I would easily last a day on my iPhone 4. I have juice defender, lowest screen setting, custom kernel with under volting. I think it has something to do with my area. Att is so congested in my area I am barely able to use data sometimes. It's better with lte but still an issue at times.

People use their phones differently. Just saying.
If I don't turn the screen on, with LTE data, my phone dies in 9 hours (I tested it). And this doesn't mean there's a problem with it. I have around 15 different push notification apps running in the background, all of which are using data almost continuously. I don't think I can expect it to last much longer. And if I know I'm not going to be near a power source for longer than that, I simply turn off syncing to get better battery life.
To me, it looks like the LTE radio is the biggest battery hog. Let's see if the iPhone 5 can somehow get around this problem so that other manufacturers can take note

I noticed a significant improvement in battery life once I used JuiceDefender to turn off data while my screen is off. 4G LTE is the main culprit of most of the complaints for battery life (in addition to brightness). That is going to be a big problem for the new iphone if they can't get the battery management for 4G correct. It has taken Samsung a couple of years to get the battery working decent with 4G. I have my doubts that Apple could top them the first year running LTE on the iphone. Who knows, maybe that will be the "new" feature they have been working on over the year, LTE power management. That's the direction Motorola has headed in their new RAZOR MAXX devices. We'll see, either way, the consumer comes out on top as we have more competition to drive down prices and receive better products each year.
Best battery life for SGS3
With AMOLED and Android u gotta take special measures to get good battery life:
- kill bloatware. NostalgiaTurboSlim script will help. Or freeze unneeded apps - like Maps and enable them only when needed.
- disable various notifications - Play Market, WiFi etc
- disable ads - root and download AdAway app - they steal your mobile traffic, battery life and make you blind!
- put dark nonLive Wallpaper
- remove any widgets you don't use. I just removed all of them.
- disable animations and transitions
- disable haptic feedback
- disable touch tones/sounds/vibrations
- try using nonAuto brightness (I gave up on that - sunlight does not allow me to change anything manually)
- disable autorotation
- use dark Opera browser user.css
- use inverted or dark themed apps and Gapps, there is dark MMS, Twitter and Facebook in my ROM
- downclock CPU to 1GHz, or enable PowerSave On.
- use modern KToonsez kernel with PegasusQ governor, it downclocks CPU during screen off
- use CPU1 disabler script if your ROM/kernel supports it
- keep chargers around you, buy them at amazon
- buy spare OEM battery - I'm against aftermarket batteries, they are all fake rated
Or just buy latest iPhone 5 and enjoy.
Remember: Android is for tinkerers! That's why we love it! :victory:
Why do people still use some sort of battery management app life JuiceDefender or the like.
GET RID OF THEM NOW !(most of you that use it are probably coming over from an Iphone so you may be new but aren't well educated in how the Android OS works)
This phone comes with its own Task Manager as well as removing unwanted apps that are running in the background that you have previously used and don't need running.
So get rid of these dumb apps that don't do anything.

I bought a 3150 man battery on eBay for 10$. With data on WiFi on . My battery took 30h to be completely drain. 5-6h of the 30h was heavy use ( game, download, watching video)
I'm on cm10 with kt747 kernel OC to 2106mhz UC to 96mhz
Ktoonservative governor
Noop scheduler
All my frequencies are under volt of at least 100mv each

I believe this is the software bug that can be fixed in one of the threads around here. It deals with the Cell Standby that drains the battery.
Correct me if I'm wrong.

So over in a Development thread I mentioned that I use Juice Defender Ultimate still, I got some heat for it because it's old.
What's new that I should be using instead? Running CM10 11/30 Nightly that I v6 Supercharged (Die-Hard, so I don't think Tasker will work).
I don't need anything to sync or notify me when it's in my pocket, just calls/texts via radio. I also already use CPU Sleeper and it's locked in memory via v6 bulletproof.
My goal is to make the most out of my battery.

not sure exactly. i used to use green power battery. these data killing apps used to work miracles on gb and froyo. but nowadays i think the main battery killers are the hefty processors. i now focus on kernels and governors and whatnot to save battery. i think killing data will help if it stays off most frequently. when you have the settings to turn on data as soon as the screen turns on, the device is toggling data and constantly searching for signal, maybe even killing more battery than saving.. idk thats just my opinion. and on the other hand.. if your not really using your phone so much i think it would save more in the long run. i would just test it yourself and see what works
Only thing that will improve the battery is a new phone .
I've tried everything. The best result has been ditching AOSP and going back to TW. It might not be fancy schmancy, but it functions and has marginally better battery life (at least in my experience).
Good luck on your quest. I'll probably keep my eye on this thread to see if there are any new suggestions (but not very optimistic).

I unistalled JD and set a CPU profile to reduce clock speed on lock, testing for wakelocks now as well.
Anyone know best governor/scheduler combo for battery on CM10 while still keeping it buttery? Im using OnDemand/Deadline for a few minutes and it has not dropped yet.

Sorry but no one can say for sure whats a rock solid combo. I suggest you try them all like I have to see what works best for you. After trying everything I came back to Ondemand and felt it gave me the best results but thats me.
Good app to try is Llama and its free and does all JD stuff and more
to add, regardless of what kernel i use sometimes the processor will climb to unnecessarily high frequencies when the screen is off. to tame it a little more use setcpu and enable profiles. my profile, when the screen is off, is min 384 max 540 and conservative/noop. then when the screen wakes, interactive/noop 384/1512. but im sure most of you already know this. cpu sleeper will do the trick too. beware of wake lag

I'm using the same Anket battery. I followed everyone's advice, ditched JD and made a SetCPU profile.
I think it was Google Music draining my battery so bad. It's absolutely amazing now.
Sent from my SAMSUNG-SGH-T989 using xda premium
I no longer use Juice Defender and, for me and my set up, JD did not have noticeable impact.
Nor did more complex strategies using Llama.
The ROMs, governors, CPU settings, and tweaks seem to be where it's at.

I have found that to be the case with every such app I've tried. The best results I've always had have come from removing apps that I don't need or use. I can get thru a full 8 hr shift, so I'm happy.

3 to 4 hour screen time here and gsam currently has me at 1 day 5 hour battery life average. without juice defender. I got rid of it when I saw it was waking my phone 150 times a day.
Hello guys,
a few days ago I bought the notes 8.0 wifi and after a few hours they already had administrator permissions.
I left the tablet that becomes exhausted and completely after a night in office, in the morning I started to make some changes: new rom and kernel immediately immediately!
I state that in Italy are the CEO of an interesting blog where we treat only Google Experience products novel that I'm not really, but ...
Turning now from the Nexus 7 (I still have it) the difference for the better I feel about this tablet but I have noticed, however, an excessive drain on the battery, then not doing anything so important: the hours of active screen only 3/4 albeit with wifi always on!
I tried to set all the Governor also present with heavy undervolt but I have not noticed noteworthy improvements ...
nb. Rom and kernel belong to @civato
Tell me your experience, thanks guys
I didn't understand all of your post, but wanted to share my experience:
Leaving the screen brightness on auto is essential to get reasonable battery life. On full brightness my tablet battery runs out way too fast. I do think this device has the shortest battery life of 7 other tablet/phone devices I have previously used for multiple full days (I cannot judge with less usage). But as long as you leave it on auto brightness most of the time, it has managed to get me through each business day since it was released.

thanks for your expertise ...
you are absolutely right but also the tablet in standby consumes a small percentage of the battery, that's not good, at least to me.
I'll talk with the developers for the right settings in the kernel ... hopefully
I found that I only use a few percent when its in stand by. Heres what I have my settings as and why
Brightness - either auto +5 or 50% switching between the 2 as required.
Sync off.
Power saving mode - on unless I want to play resource heavy games.
GPS off. only turn it on if an app specifically requires it (navfree)
Bluetooth off.
spen battery saving mode on. the spen layer uses charge so no point having it on unless i need it. if im using my 8pi pen i just leave the spen out a little, using it like a switch.
Other battery saving things.
Auto airplane mode - app that turns all the signals off when the screen is off.
trickster mod - under volted by 75 on the CPU accross the board (had a few crashes on 100). also undervolted the GPU and changed the ramping threasholds.
- govner set to lulzactiveq which is a modified interactive but also with the benefit of limiting the cpu when the screen is off.
- set ignore_nice_load to 1. so that nice to have processes are now no longer run. only the higher priority ones are.
greenify - set various apps to hibernate stopping them from taking the tablet out of sleep.
Think thats everything.
The primary settings you listed @hertsjoatmon, are standard on Android (and better on Samsung devices) say: I will use them for years.
The second part is more interesting, in fact undervolt to -75 they had not yet tested on this note 8 but if you tell me that the tension holds well-being.
Also on the GPU did you apply the undervolt?? mmmm
The Governor me most is satisfying, at least in terms of battery life - albeit with some lag micro - is "ondemand" (100 -> 1200) with frequency freeze (of 4 cores), thanks to kernel @civato :good:
Standby does not consume almost nothing but if you use the goodness of the screen, wifi and all notifications accesse lead to excessive battery consumption that even my Nexus 4 behaves this way (having then 2100m)
