Best battery life setup.

Just wondering which rom/tweaks you guys run to get the best battery life for every day use. I cant get any more than 10 hours with the CM7.0.2 rom.
I really don't use any tweaks. I just adjust the brightness of the screen throughout the day.
Autokiller.
And make sure your not constantly syncing stuff. Like gmail,facebook or weather. Stretch out those sync intervals as long as you can manage. Or just refresh it manually when you need.

Download Battery Monitor Widget and it can create a graph of usage over time and start watching what is running and when the phone draws current. You can learn a lot by watching the usage, how often and how much current gets drawn even when the device is sleeping.
The three biggest users of power are the display, voice calls, and GPS. Both GPS and voice calls draw about the same, the display uses less but between the three they are hogs compared to what else is usually running.
I have the same troubles and will try these things. Thanks for your help!

Battery Tweak Suggestions
Well there is the Collin Battery Tweak that I used when I was running AOSP 2.2. It worked wonders. I was able to get about 3 to 4 days on it without having to rechange. However I am not certain this will work on CM7.
What settings are you using under CM Settings > Performance ?

Battery Life?

How long does a full charge last for you on your continuum?
I got a new warranty replacement battery from verizon yesterday, because my battery only lasted 4 hours. This was with turning off applications and having the screen off. I also have the brightness turned all the way down for when I actually use the phone.
Right now, Im running Adrynalyne's kernel and the "3.30.11 Clean Continuum DL17 Rom". I hope this battery lasts.
Mine will usually last all day (around 12 ish hours) with moderate use (meaning checking facebook, browsing the internet lightly and checking email, making calls and texting). I've never had a problem with my battery except when I first go tit and I couldn't put the thing down lol
Tricks to get your battery to last longer:
1. Get "Advanced Task Killer" from the market and kill all unnecessary processes that run. The Task Manager that comes on your phone can detect applications that are multitasking, but it can't detect processes. Processes can randomly start running when you open apps like Facebook, Browser, etc. When you press the "back" button to exit an application, these processes keep running and consume lots of battery life. I saved muchos battery life with this app.
2. Go to Settings>About phone>Battery use and see what's consuming the most of your battery life. Click on the items you see that are consuming battery life and it'll tell you if you can do anything about it.
3. Live Wallpapers consume a considerate amount of battery life, so if you're having battery problems, avoid using them.
4. Remove unneeded widgets.
5. A friend told me using battery conserving apps actually increased his battery consumption. I don't know if it's true, or why that would be but I would try testing to see if using a battery conserving app actually helps, or makes it worse.
6. Turn off WiFi when you're not using it, or it will constantly attempt to search for WiFi, decreasing your battery life.
7. Try using SetCPU, and set a limit to the processing power (is that what it's called?) that your phone can use. Don't set it to the minimum because you don't want a laggy phone, but try lowering it a bit and see if that reduces the amount of battery life used.
If that doesn't work, nothing will. I don't know why you only have 4 hours of battery life, but that should fix anything that makes your phone have less battery life
There's a better apparently than adv task killer it has like 5 apps in one its called android assistance. And its worth looking at trust me

[Q] Randomly bad battery drain

About a month ago, I was running RoyalGinger 3.0 with bluetooth, GPS, and background data disabled, and I was only using my home wifi to get online. My phone would pretty much hold a 100% charge for 5-8 hours if I left the screen off. I was pretty amazed at my battery life. Then I decided I wanted to try a different rom, so I backed up in CWM and did that. When I returned to RoyalGinger, my phone wasn't holding the 100% charge for as long anymore and hasn't done it since then (yes, I did re-calibrate the battery, like twice at least).
Recently though, my phone has been having horrible battery life under the same conditions. The only difference is that now I use LauncherPro instead of the stock launcher. I'll charge to 100% + 15 minutes or so, and with the screen off, the phone divebombs to about 95% within an hour and a half. If I actually use the phone, it will lose 30% in 2 hours. I have no idea what the problem could be since I don't have any data-syncing apps in the background and I'm really just texting people.
Any ideas?
The consumption doesn't sound like anything out of normal. A difference in signal quality (radio or WiFi) or using radio for data instead of WiFi can cause that.
In any case, just check the apps that use your battery, and see that you don't have any process getting CPU stuck on 100% (you can see CPU load in System Panel Lite, for example).
Download the apps below.....this will help you out.....
Use the app SetCPU for Root Users
It allows control of certain aspects of the Linux cpu freq driver, allowing for overclocking, underclocking, or tweaking speeds and settings. Download it here.
Use the app Battery Booster
Battery Booster is a powerful battery boosting tool and power management application specially designed for Android devices. Download it here.
Always remember to remove the charger immediately when the battery level reach 100% for longer battery life.

[Q] Battery life terrible, despite trying all the supposed "fixes", hardware problem?

[Q] Battery life terrible, despite trying all the supposed "fixes", hardware problem?
I got my N4 a bit less than a month ago by this point. I've rooted and tried most ROMS from stock to CM10.1 to PA, etc. However, my battery life is consistently not so good. Coming from a One XL on CM10, I was used to bad battery life, but I expected the N4 to be better.
I don't have any screenshots, but here are my averages:
Time on Battery: 10-14 hours
Screen on: ~1.5 hours (usually, never have gotten over 2.5)
Android OS kept awake: ~1-1.5 hours
I know I'm among the group of people with the problem of Android OS keeping the phone awake, and I see all of these kernels attempting to fix the msm_hsic_wakelock issue, but I'm still having that as well.
I'm always on auto-brightness, Google sync on (calendar, chrome, gmail), Google Now enabled, etc. I'm also always on data, usually 2 bars + (the signal never gets worse than yellow on the battery graph.
Lastly, on wifi, all of these issues are gone. My idle battery drain is also phenomanol on wifi compared to data or even no wifi + no data. In about 8 hours I drained ~8% even with the data off.
Any ideas? I'm getting really frustrated. I see people claiming 2+ hours screen time or 20+ hours on battery on stock phones! I'm nowhere near the average battery times.

Android OS is not keeping your phone awake. It's one of those crappy apps you have installed that are causing a wakelock causing the phone not to deep sleep.
Download: http://forum.xda-developers.com/showthread.php?t=1179809
Use it to debug partial and kernel wakelocks (primarily partial wakelocks). Check CPU states using that app or download CPU Spy from play store.
It needs to be deep sleeping.
Google Now: Disable cards that you dont use.
Turn off auto brightness and adjust it to your liking (CM10.1 has a feature if you long press on status bar it will adjust its brightness so you can do it like that).
Use Franco Kernel r23 (it's the most stable one, if you want to experiment you can try r26).
Google Maps: turn off Google Maps Latitude and its automatic reporting of your location and uncheck auto reporting in your location.
https://play.google.com/store/apps/...xLDEsImNvbS5iaWdleWVzMHgwLnRyaWNrc3Rlcm1vZCJd use that app with Franco Kernel (or buy his app) to adjust its kernel settings.
http://zephik.com/upload/Screenshot_2012-12-14-19-05-58.png is a screenshot from last month. Pretty good battery overall for me.
Press the thanks if I helped. Will reply back if you have any questions or follow ups.
I've been on CM10.1 nightly 1231 for 3 days now and I can happily say that my battery is much better than before.
I've averaging 24-28 hours with 3 hours screen on with data only and usually charging at around 10%.
Always Enabled:
All Location Services
Google Sync
Always Disabled (except when needed):
Google Maps/Latitude location settings
Bluetooth, WiFi, GPS
Google Now cards that I don't normally use
Some things I've noticed:
- When I flash a new ROM and restore my TiBu (flashable zip or regular restore) I find that my battery life is average at best.
- When I flash a new ROM and fresh install my apps from the Play Store my battery life is good to great.
- Third party kernels can sometimes be wonky on this phone. I haven't tried Faux or Franco kernel since flashing 1231 because I've been getting great performance on CM kernel.
- When my kernel CPU is set to "ondemand" the performance is average at best. Changing it to "interactive" has helped improve my battery life... with no other kernel tweaks involved.
Apps like Facebook and Facebook Messenger seem to cause issues with my battery life also. When I was on CM10.1 nightly 1223 I had Facebook Messenger installed and my averages were 12-14 hours off battery. So by eliminating a few apps on fresh ROM installs I've been able to see the different effects they've had on my battery life. Basically any app that uses GPS can potentially be a battery hog even when the phone is not in use.
So from my points above are also some of my takeaways. Try a fresh install and watch what apps you install. Try a few different kernel governors (esp if you're on a custom ROM). You can improve performance by trial and error!
Good luck.
EDIT: zephiK's points above are also valid and I can confirm they've helped my battery life also.

I agree 100% with Facebook. The facebook app sucks your battery life HARD, especially if you plan to have it refreshing intervals. The app continues to request GPS location, so therefore because of that I disable the GPS on my phone completely (its that bug where if u have GPS globally on your phone you see it on the top left of your screen, and it doesnt go away). I leave FB all notifications off and manually sync it by pulling up on news feed. It's either that or check FB via mobile webpage.
Another thing I forgot is your refresh intervals. Make sure your apps don't have it on like syncing every 5/10/15/30/45/60 minutes. Set it to a couple hours more. using a twitter app? instead of having it sync in the background, just manually do it so you get all the missing tweets all at once. No reason to have it sync in the background randomly.
+1 on interactive. on Franco kernel it uses Interactive as it's default governor and it includes a lot of the latest interactive patches that really help out. It also includes qualcomm fixes with msic (not 100% but its better than stock), and newer drivers that will most likely be included in the next OTA.
Thank you for the replies everyone. In regards to all of the fixes you've suggested, I've tried all of them in the past week or two based on hours and hours of reading. This problem even exists on a freshly installed ROM with the bare minimum apps.
Now that I think about it, I wonder if there may be a problem with the radio in my phone. I live on a farm with an AT&T tower, yet I'm only getting "ok" signal, when I should be getting perfect signal. Called Google and just ordered my RMA, seeing as this battery problem has persisted from the day I first loaded up stock 4.2.1 on the phone upon receiving it.
If you constantly have a low signal, that will drain your battery a lot, because it has to boost the signal and that needs a lot more power.

This would have been useful in your original post. Obviously "worse" signal is going to cause more drain on your battery. Hopefully it's just a flaky radio for you but if the replacement has the same issues then it's something else and you should keep at it until you figure it out! That's half the fun with these phones.
My only concern was that he said android os was up there, so that means he has a app preventing his phone from sleeping.
personally i wouldnt take a RMA on poor battery life but as a result due to signal.... but yeah signal does play a huge factor in your battery life

[Guide] Optimizing Battery Life

Hey Guys, Kyuubi10 back again with a quick guide on improving the battery life of the HTC One M8.
Let's be honest, this phone is getting quite old now. You can already start to feel it lagging, and slowing down. And the battery doesn't last as much as it once used to.
But don't give up hope...your M8 isn't dead yet, and with some good management it can even rival 2016 flagships.
Let's begin with Marshmallow...
If you have not updated your M8 to Android 6.0 yet, WHAT ARE YOU WAITING FOR?
Marshmallow is the best version of Android yet, the efficiency of Lollipop with the Stability of KitKat, and a very fresh take on Battery saving!
Reasons why you should update ASAP:
1 - Lollipop's memory leaks 99% fixed (Don't want to say 100% due to the possibility of some existing out of my limited knowledge, but for all intents and purposes there are no more memory leaks.) This is very important, because the memory leaks were both draining battery life, and slowing down the device...which in turn keeps the screen on longer and wastes even more battery.
2 - Doze!!! It's the latest battery saving feature to be added to Android, and it's basically a SUPER idle state, where the phone if left untouched with screen off for long periods of time will not waste any battery whatsoever! I tested this when going to sleep, phone was in airplane mode, battery saver turned on, screen brightness at minimum...I left it at 100% charge, I woke up it was still at 100%. With airplane mode off, and battery saver turned off the phone lost only 3% battery overnight.
This being said, true battery saving is measured while using the phone right?
It's not about how long it can last without being used, but how long it can last while being used.
But what if you already are on Marshmallow, and your battery life is still not cutting it?
The following solutions are organized from simpler to more complex.
1 - Follow this official HTC guide: Tips for extending battery life. It provides tips on reducing screen brightness, keeping connections off when you're not using them (Wi-Fi, Data, BT, GPS, NFC etc...), lowering volume and vibration strength and using power saver mode.
While their advice is quite obvious stuff, and most of you probably do it anyways, I would like to stress the use of power saver mode when you are out and about away from a convenient power source. Doesn't matter if your battery is at 90%, turn PS mode on, you will barely even feel a difference, but your battery will last you much more than before!
2 - Buy yourself a smartwatch. While it may seem counter-productive to keep Bluetooth on constantly to keep connected to the watch, it actually improves battery life by helping you avoid turning on your phone's screen. At the end of the day the battery saving that comes from it may be equivalent to the drain caused by bluetooth being on, or even greater than the drain. Thus effectively saving you battery life, and being convenient while doing it.
3 - Here comes the big one...ROOT your device and install a custom ROM and Kernel. Just by installing an optimized ROM and optimized Kernel you will get battery savings + better performance. Often you will also have settings you can tweak to optimize battery savings at the cost of performance or vice versa. And with a custom Kernel you can choose one with battery saving CPU governors.
4 - CPU Governors. CPUs, just after your screen, is the second most battery consuming hardware part in your device. Especially since it is on most of the time. Choosing a governor that can make it's job more efficient can save you bucket loads of battery.
The most common one for battery life is called "Conservative", and it will provide you with considerable battery life at the cost of performance. But if you want both good performance and good battery life then you are probably looking for a governor which employs the "Race to Idle" ideology. (If you don't know what it is, do a quick google, it's easy to understand.)
A good option I like to recommend is Wheatley, but if your kernel choice lacks it then interactive will be good enough...but you will have to tweak it's settings yourself to make it most efficient. Couple months ago I created this guide which you may find helpful when tweaking the interactive governor.
5 - Since we have spoken about Rooting then let's start adding some ROOT apps to the mix. Greenify would be my first recommendation.
For 2 main reasons... 1, It helps you stop annoying, battery draining apps which keep themselves running in the background. 2, It's latest versions have included a feature where you can set Doze to start sooner than default. Thus allowing you to reap Doze's benefits earlier and for longer.
Talking about the annoying apps, there's one in particular which comes to mind....Facebook.
Personally, while I don't like it's battery draining, I also don't want to uninstall it...since it's quite useful. Thus in Greenify I found my answer!
6 - Last but not least, if you are noticing unusual battery drainage, but you can't find which app is causing it (or may even be a system app), or if you notice that Doze is not having any effect... it might mean that a wakelock is not letting your device idle for long enough for Doze to start.
For this you will need an app called "Wakelock Detector". Charge your phone to around 80-100% and place it on a desk and let it idle for a couple hours (e.g. When you are asleep). When you are back check what WD found, and it might surprise you. (I found an app called HTC Mode which was keeping my device awake and preventing Doze from starting.)
Another advantage of this app is that once you find the wakelock it links you to Greenify through which you can put that specific app to sleep. Thus preventing it from setting the wakelock again.
If you follow all these steps, you should be able to feel the considerable difference in battery life. Reminding you why you fell in love with this device
I hope I have been of help, I noticed that there weren't any Battery Guides specifically made for the M8, so I thought I would leave one here in case anyone is looking for one!
If I have helped you make sure to hit that :good: button, I will greatly appreciate it, and you will be helping the community find this guide more easily.
Thanks for reading! Enjoy your longer lasting M8!
Thank you for the Info! Before marshmallow I used "app ops" but this doesn't work on Android M. Because of the app wakelock detector I removed the messenger app from facebook. It drained my battery. Thank you.

App ops is good for permissions, and stopping an app from connecting to the internet. Android M already has a permissions feature natively included.
What you want is to stop it from running in the background.
While you can uninstall it (and probably find another app which you can use facebook messenger in. e.g. Disa), I would personally recommend you simply use greenify to put it to sleep.
All official facebook apps are huge battery drainers, but greenify will keep them in check, so that you don't have to use another app with less functionality.
Obviously I am not forcing you lol, but it is my recommendation.
