How to maximize battery life without affecting functionality? I think the answer for this question is different for most of you. It depends on how you plan to use your device, even when it’s not turned on. Keynote is that you have to get the right tools and be creative. To give you a head start, I will dump my configuration in this thread. I am able to get up to 48 hours on one charge using this configuration. If used more intensive, your results may differ from mine though.
My configuration
HTC Desire
DeFroST 2.4d
DeFroST 2.4d"]DeFroST 2.4 SVS 1267Mhz kernel
SetCPU
Setting Profiles
DeFroST 2.4d
I will stick to this ROM for this guide but I’m sure the following applies to your custom ROM as well. DeFroST is my personal favorite and I would like to use this opportunity to thank RichardTrip for all the time he puts into this ROM.
DeFroST 2.4 SVS 1267Mhz kernel
DeFroST 2.4 HAVS max 998MHz 800mV (max 998MHz) might be better at saving more energy. But my decision to pick the SVS 1267Mhz has couple of causes.
I don’t have a CPU that can run at 800mV
I’m not patient, I love to go to max speed when it’s available
I found that with my current settings, battery life is good even with the SVS kernel
As I said, it’s totally up to personal preference. If you feel you need it, flash it! There’s a 925mV kernel out there as well if you have the same issue I do with 800mV (running unstable).
SetCPU
Freely available to any XDA user. A lightweight tool that offers all the functionality we need. Other then setting the default speed, it allows us to use profiles based on things like battery charge and temperature.
Main
Profiles
In my configuration, the phone runs at full speed when the battery capacity >= 75% or if it’s charging. Then when the phone discharges, it gradually scales down the max CPU speed. More important though, I found that I don’t need to have the device running at max speed, seeping energy, when I’m not actively using it. When my display turns of, my max CPU speed will be set to 245Mhz. This is perhaps the most important setting in this configuration.
Setting Profiles
No, not Juice Defender. I don’t know why so many seem to prefer Juice Defender. It cannot be customised the way I like it and the UI gives me a headache. But then again, that’s my opinion, maybe I’m wrong
Setting profiles is once again a lightweight tool that lets you define rules by means of logic. It works like this (example):
Create a profile that enables WiFi
Create a rule Activate WiFi when the condition battery is plugged to any charger is met
I figured that I do not want to receive mail, connect to bluetooth or WiFi when I’m asleep. Also, I don’t need a constant e-mail sync at daytime. 50% sync activity is enough for me. For now, that’ll do.
Profiles
Rules
I have a lot of ideas that can still be implemented. The devs at probeez.com are working hard to implement new functionality into their app. One idea I had was to revert to 2G when the display is turned off. However, the condition display off and the action revert to 2G are not available yet.
If you agree, please let the devs know what functionality needs to be added to make their software even better. Vote on this site.
The 2G functionality has already been planned. My other suggestion, the display state, doesn’t have enough votes yet. You can find it here.
The good thing about this tool is that it will be highly customisable when more and more options are added. This fits the idea of choosing your own energy efficient settings I’m trying to promote with this topic.
Conclusion
I could elaborate my choices, but my point is to give you tips about how to address energy saving. Read this manual and be creative. Copy some of the ideas, change others. Maybe come up with new ideas so brilliant that I should add them to this post .
I’ll try to keep updating this topic with the input from you and the newly available functions in the apps.
Other Recommendations
Manual control of brightness
How could I forget? My own brightness setting is always at the lowest. Unless I'm in a very bright environment (like in the sun) and I cannot see anything on my screen. Auto brightness tends to be to bright in general. The Power Control widget can assist you in quickly switching brightness.
-prove
Use a plain black wallpaper
Although this goes further them some of you want to go, using a plain black wallpaper can save battery usage.

Added. Thank you.
Although there is not a huge improvement, I'd recommend you to have a plain black wallpaper. It actually saves a few percentages, if you do a quick search around the forum you will find the thread.

Personally I think this goes a bit to far for me. I like active backgrounds, like the one that reflects weather and daytime. However, it's a good idea. If someone can find the link to the detailed topic, I'll add it.
here is the link to the topic. The thread includes tests and results.
http://forum.xda-developers.com/showthread.php?t=660853
is it safe to assume that the profiles that let you enable or disable wifi are in the full paid version ?
*edit*
scratch that, just found 'setting profiles' on the market.
i did lose 2% battery life with just 5 minutes surfing ealier on ..
I have never used any additional program to control power apart from the default Android power widget. I would normally do this to preserve energy no matter which ROM or even which phone I have. It's all common sense:
- turn "2G only mode" and switch on 3G hen I actually need it (e.g. browsing heavy webpages). If you turn off the images in websites even GPRS usually does the job well.
- NEVER use 3G for regular voicecalls. It's a completely senseless way of draining battery fast.
- completely switch off any automatic syncronizations (Gmail, Facebook, Weather, etc.) and syncronize individual accounts only when I actually need it. Simply untick the "automatic synchronization" in the accounts and sync settings.
- of course wi-fi, gps are permanently off and I turn them on manually only when I need them.
- keep the display as dark as possible and no brighter than needed.
- use a solid black wallpaper which saves energy on AMOLED screens (won't make difference on regular TFT LCD). A bright wallpaper may significantly increase energy consumptions.
- forget any "Live" wallpapers.
I have read that killing tasks does not make much difference on Android 2.1 onwards. I still keep killing tasks just as a habit.
This way it adds up a bit of extra manual job but I think it's better than any of those "power control" programs that do the same thing just not as accurately as one can do manually.
well i left my phone on charge overnight and unplugged it at 8am this morning on 100% battery.
6 hours later and it's on 96% - although to be fair that's with near zero usage.
thanks for this topic, very helpfull

thanks !
I have just implemented everything you recommended, so lets see how tomorrow goes (I can't be bothered to go drive out of my local cell towers ranges right now to see if my WiFi turns off ).
With regards to Disabling Sync, if I set it for 4 minutes out of 5 minutes (4/5) then Sync is only enabled for 1 minute out of every 5 minutes, right?
Having previously used JuiceDefender, I thought I'd give Setting Profiles a bash. First stumbling block is lack of toggling for mobile data - is that right, or have I missed something?
I'm new here & making this thread in order to share my own experience plus what I've learned from others since there're a lot of concerns regarding battery life.
Followings are what identified as the most power consumption sources and we'll fix them 1 by 1:
1. HD screen: I usually set the display brightness manually to about 15-20%. It is quite acceptable as I almost stay indoor at day time (surely this will make your screen nearly blind at this level if you try it outdoor under sunset)
2. Duo core 1.5GHz CPU: Having your CPU at this speed makes your phone soooo hot for heavy tasks. I use SetCPU to set the speed to 1188Mhz max and 192MHz min and also use SetCPU to enable the Screen Off profile where the max & min speed both set to 192MHz (there're no reasons to run it at high speed when the screen is off, right?).
3. The stock home launcher: I found the stock launcher (called LG Home) always takes a high portion of battery so I replace it with Go Launcher. This app also has a nice feature where you can see and close all running programs so you won't have to install another task killer.
4. Bloatware: Firstly, install Titanium Backup and "Freeze" whatever bloatware you found in this list (thanks youngv408) including the LG Home but only after you install & use Go Launcher. Secondly, install Gemini App Manager, at its home screen you will see running apps, for each of them that you don't want them to autorun (no more running in background & no more auto restart if you kill it), tap on the app name > choose More Operation > Config "Autorun" (root) > disable all of its autorun options (don't ever disable or freeze the Go Launcher if you are using it!)
Above tips keep my boy easily survive 1 day with 50% battery left (with 5,6 phone calls, some SMS, some 3G for web & downloading and little gaming). Hope they help.
All good tips, thanks!
Some good suggestions except for maybe #2. Personally, I found SetCPU had a dramatic negative effect on my battery life. Uninstalling it netted me several more hours with average usage immediately. Also, don't use task killers other than the built-in features of Gingerbread to kill a misbehaving app. The OS already does a good job managing running apps. Turn off GPS because some apps like to ping your current location occasionally and GPS uses a lot of juice. Finally, make sure apps like Facebook, Twitter, Google Plus, Google Currents, Gmail, etc. aren't set to sync too frequently.

According to battery use info smaller cpu clock resulted in more cpu total time usage
This battery gets better everyday... never had this experience with another phone.
Weird is, that after i no-bloated and did some tweaking in the beginning, the batterylife was still very disappointing. It seems that it is growing with the user...
we can turn off wifi or 3g if we don't use them,so we can extend the time
Hey all,
I wasn't able to find any conclusive details regarding this topic, maybe you guys can shed some light for me:
In the hidden HTC powersaver options for the HOX, we have the option to use "Reduce CPU speed"- which is set to 'on' by default and its function being explained as then only using a single cpu core and reducing the speed to 1Ghz.
Even though the explanation is rather straight forward I'd like to know exactly what this option does.
Does that mean the CPU is throttled for 'normal use' like browsing, using simple apps, (...) only and is being reverted to its full capacity when (eg) playing games? Or in other words, where exactly is the threshold here?
I find my HOX a lot smoother in response (ie scrolling, surfing) when de-activating this option but battery drain also seems to go way up.
Thanks guys.

Its hidden in the settings, you can access it through downloading Minimalistic Text in the play store then set up a temporary widget that leads to settings under activities and search for power saver settings. Then just tap on the widget and it should lead you directly there/

Are all of these options on this tab only effective on a battery lower than 30% because some of them say that the data conection is only on with the screen on..
And If it's only on a lower 30% battery I will leave them on otherwise I will just turn them of.

Q: Formatting my SD Card as Internal Storage doesn't work. How to fix it?
Goto Settings > Storage. Click on your external sdcard
Tap the Menu button in the top right and select Settings.
Then choose Format as internal. (This erases all the data on the sdcard so backup if necessary)
Once you click Erase & Format, the device will format your card.
The process may get stuck at 20% and timeout after about 2mins. If it does reboot into recovery after it times out.
In TWRP, select Wipe then Advanced Wipe. Select "MicroSD Card - Data" and click "Repair or Change File System".
Choose, "Change File System" and select FAT. Then swipe to change.
Reboot, then goto Settings > Storage. Your sdcard should appear as corrupted.
Continue and format as internal storage. It should then get past 20%. If it does, continue with the steps shown to you.

[FONT=Arial,Roboto,Helvetica Neue,Helvetica,Verdana,sans-serif]Frequently Asked Questions[/FONT]
Since this is a unified thread, I will use Celox to refer to both the Hercules and the Skyrocket. This was their planned codename for the LTE S2, and both use the celox-common branch in source code.
Q: How do I root my Celox? I flashed SuperSU, and my phone won't boot!
A: You don't need SuperSU. Root access is baked into the ROM.
Wipe everything and install the ROM without SuperSU. Now, in Developer options, set Root access to Apps and ADB. If you really, really, want SuperSU, install it from the Play Store and have it install it directly without recovery. (not confirmed working, but should work.)
Q: Do I install this like any other ROM? Why can't I install Gapps?
A: No. This is a virtually partitioned ROM, common in today's Celox ROMs. The different partition layout is necessary to take full advantage of your phone.
Q: Clean flash or dirty flash?
A: I always dirty flash. I never wipe unless I am switching ROMs. You may want to wipe, your choice.
Q: Virtual repartition? Whaaaaaat? Do I need a PIT file? Will this damage my device?
A: The classic issues with the S2 are:
Not having enough room to install apps
Being forced to use tiny Gapps packages
having waaaaaay too much internal sd card free space, even when you have a real SD card that you haven't filled up either.
Virtual repartitioning changes the way the system sees the partitions ("sections" of the 16GB of storage), making it similar to the 16GB Samsung Galaxy S3. This fixes all of those problems!
Here is what happens:
To make more room for apps and data, we made that SD card partition multitask as apps, data, and the internal SD card storage, emulated at /data/media/0, like modern devices. This will wipe those files on the internal SD card partition, though! You now get 11.2GB freely usable by the system.
Since Lollipop, ROMs have been increasing in size greatly. They even use a different installation method. Our measly 598MB /system partition, which couldn't even hold all of 4.1.2 TouchWiz, has been moved to what /data was before. That means 2GB for the ROM, Gapps (yes, you can even flash STOCK!), BusyBox, root stuff, extensions, you name it!
And that 598MB /system partition becomes /cache, because you can always have more cache!
No PIT is needed, and, if you flashed a PIT (like the one that gives you 6GB for data), flash it back to stock! You will end up with 7GB shared for the internal SD card and app data and 6GB for /system, which is ridiculous.
And the best part is: Nothing is damaged. It is 100% safe! It is just a renaming scheme, and you can always flash to stock in Odin.
Q: Which Gapps should I use?
A: Well, as always, it is your decision, so so as you wish. I personally use Nano, which I also recommend. However, you need to install keyboard_patch.zip (attached to this post) after a Full or smaller Gapps or you will get spammed by "Unfortunately, Android Keyboard (AOSP) has stopped.", making it impossible to set up your device.
Stock fixes this issue, but it also adds crapware that I bet you don't need, like Google Sheets, Google Maps, Google+, and especially Chrome.
Q: HALP!! I'm getting "Unfortunately, Android Keyboard (AOSP) has stopped.", I can't set up my phone, and I am about ready to throw this thing at the wall!!!!!1!
A: Calm down. Breathe. I know it is annoying and gives you headaches.
Just reboot into recovery (using the key combo), and flash keyboard_patch.zip, attached to this post.
Q: Whenever I browse the web in Chrome, my phone goes berserk! It slows down, shows me black screens then the lockscreen, etc.
A: Don't use Chrome. The stock browser is about as good and doesn't wreak havoc to our device. However, this is replaced when you flash a larger Gapps package. I recommend using Nano and installing what you want instead. Just wipe system, flash ROM, Nano, keyboard_patch.zip, and reboot. Alternatively, you can use Opera, which has everything Chrome has except Google account bookmark sync and bloat.
Q: I have one of the following issues:
Calls don't work. They reboot or say "Cellular network not available."
When I turn on my device, I don't have a data connection.
A: You flashed the wrong build. Flash anything after 20160126 and those issues are fixed!
Q: My battery life is bad.
A: Here are some general tips I use:
Turn data, WiFi, GPS and Bluetooth off when you are not using them.
Understand that lower signal = shorter battery life.
Settings > WiFi > Menu > Advanced > Keep WiFi on during sleep > Only when plugged in.
Settings > WiFi > Menu > Advanced > Always allow scanning > Off.
Black wallpaper = good.
Underclock/undervolt.
Lower brightness to the minimum you can see.
Enable the Power saver profile (currently not working on 2/16).
Install the blacked out // regression+ theme, which makes most things black. Pure black = good.
If you really want to stretch your battery life, you can do these extreme tweaks, however, they can affect the functionality of your phone.
Green-only mode. It looks pretty awesome and saves battery life. In terms of battery life, AMOLED screens get better battery life depending on the color displayed on the screen. Green > Red > Blue. Black uses almost no energy.
Set to blacked out // regression+
Black wallpaper
Brightness to 0%
Settings > Developer options > Simulate color space > Monochromacy. This makes it so you can (mostly) see non-green colors.
Settings > Display > LiveDisplay > Color calibration and set all but green to 0%.
Download [root] Naptime (with root enabled) and enable the Aggressive Doze mode. Your phone will be practically off (only the cell radio with data off is running) and you will not receive most notifications, sans phone calls, text messages, alarms, and seriously important notifications as soon as the screen turns off. This is also naturally enabled when you leave your phone unplugged and not moving for 30 minutes.
Hold down the power button and select "Power off". This is a feature that causes your phone to use absolutely no power, however, your phone will take about a minute or two to exit this mode and you will not receive any calls, notifications, texts, or anything and WiFi, mobile networks, Bluetooth, GPS and the CPU will be disabled during this mode.
Q: After 30 minutes of my phone's screen being off, WiFi turns off. I just can't seem to shake this bug!

That is called "Doze", it is a built-in feature added in Android to attempt to save battery. Jerry Hildenbrand did a good job explaining this at Android Central.
You can configure this using [root] Naptime, but it is a rather advanced tool.
Q: My keys stopped working! What did I do wrong?
A: Disable Sweep2wake in the "Advanced Settings" app. That tweak is cool, but not yet stable enough for daily use.
Q: How do I make things smaller?
A: Settings > Display & lights > LCD density.
Thankfully, they fixed the alignment bug, so you no longer need to edit your build.prop.
The larger the number, the larger things will be, and the smaller the device will identify as.
240 is the default. The 4.5 in (11.43 cm) device is recognized as a measly 3.89 in (9.87 cm). Friends don't let friends stay on 240 DPI.
Technically, the Celox has a DPI of 207, but apps work best with multiples of 20.
I personally recommend 200dpi, which makes the device identify as 4.66 in (11.85 cm). It is quite nice.
However, with a non-standard DPI (standards are 120, 160, 240, 320, 480, and 640), it can cause scaling issues like blurriness.
Q: Should I use EXT4 or F2FS?
A: I use F2FS. F2FS is safer for your data, writes faster, and is actually designed for flash memory (it is called Flash-Friendly File System), unlike EXT4, which is made for a hard drive. However, some people encountered issues with F2FS and the Play Store.
EXT4 is tried and true, and is still relevant.
Q: Why does my camera keep crashing?
A: In the Advanced Settings app, check "Force low-power flash".
Q: I get random reboots. I see the Samsung logo, then a black screen! Grr!
A: At the time of this writing, 1/26 (sometimes 1/27) is the most stable. Try flashing that.
Q: How do I remove the pesky # on the status bar?
A: Install this Xposed module, or it is also a part of this all-in-one tweakbox by the same developer.
Q: Are there any cool features in this ROM/Kernel?
A: Yes, there are more features in this than the usual CyanogenMod Celox kernel. Some features are still being worked on and are a bit unstable, but testing and fixing is welcome on our GitHub repo!

Q: Why can't I configure my CPU governors?
There was a bug in the 2/16 build that added governors, but they had issues with case-sensitivity. Flash 2/22 or newer and you get governors and configuration.
Q: When will we get an update?
A: Be patient! Or build it yourself. Don't forget that some people have lives, and some people don't have lives but still aren't going to constantly update.
I will update this with more questions and answers.

I have to differ with this point. As I have said many times in the main thread, my battery life has been awesome. I have a healthy battery. You have stated that your battery is nearly dead and that you jump through these hoops to get it to last.
I post this so that people who see this don't think that this rom is bad for battery life. It's not, if you have a healthy battery. Here are my current settings:
Screen always on Auto Brightness
Wifi Always on (even when connected to Data)
Sync is always on
NFC off
BT off
I use data about 25% of the time
When on Data I have location set to battery saving
I use the Balanced battery setting
I make all my calls through Hangouts
I have dozens of apps installed
I am using Rom V. 1/26 (dirty flashed)
My average battery life right now is about 24-36 hours with 1.5-2.5 hours of Screen on Time. And my battery charges from about 10% to full in about two hours. My best battery life so far has been about 49 hours with 1.25 hours of SOT before needing to recharge. My average Doze usage is about 1.5%/hour- this is without tinkering with Doze settings with an app.
This battery life is on par with newer devices.
edit. Here is a screenshot of my battery usage right now. Nearly two days and this is with about 1 hour of SOT

I post this so that people who see this don't think that this rom is bad for battery life. It's not, if you have a healthy battery. Here are my current settings:
Screen always on Auto Brightness
Wifi Always on (even when connected to Data)
Sync is always on
NFC off
BT off
I use data about 25% of the time
When on Data I have location set to battery saving
I use the Balanced battery setting
I make all my calls through Hangouts
I have dozens of apps installed
I am using Rom V. 1/26 (dirty flashed)
My average battery life right now is about 24-36 hours with 1.5-2.5 hours of Screen on Time. And my battery charges from about 10% to full in about two hours. My best battery life so far has been about 49 hours with 1.25 hours of SOT before needing to recharge. My average Doze usage is about 1.5%/hour- this is without tinkering with Doze settings with an app.
This battery life is on par with newer devices.
edit. Here is a screenshot of my battery usage right now. Nearly two days and this is with about 1 hour of SOT

Well,
You had amazing signal 24/7. Damn you, T-Mobile!!!!! (I miss the days of the you-step-indoors-and-you-lose-signal and AT&T users laugh)
1 hour of SOT. Try this: Marathon it. Do a YouTube playlist. Go on a Google Search frenzy.
You were in Doze 95% of the time.
David (not even gonna try to spell his username, too late at night) was also comparing his battery life to 4.4 AOKP. I have always heard that AOKP is amazing on battery life.
Update, here is my battery life. The Doze part was me using my S3 when this was on my bed, and then finally watching The Force Awakens. (PS: Great movie!)
And that is in airplane mode the whole time.
The rest was mostly me web browsing or watching a YouTube playlist.

Great job on this rom. Running great on 1/26. Didn't see it but is there a way to disable superuser icon in the status bar? I saw it for alarm, wifi, etc.... But not for SU. Just curious. Thanks.

Nope. There may be Yes, there is an Xposed module for that. See two posts down.

Yeah, I get pretty good signal here. I live in a major city. :good:
But about 8 hours of that was in an area of low signal. Also, my Doze usage was for nearly two days! And I didn't baby the phone. I just used it for messaging/calls/email and a few searches, and my calendar and updating a few apps in that time. When I plugged it in this morning I had hit 48 hours with 1.25 SOT with 4% left. I could have gone another few hours if need be.
My average SOT time is closer to 2.5 hours with about 24 hours standby (Doze). I've gotten as high as about 4 hours SOT with about 18 hours standby. I've already run a high drain test, SOT almost at 100% of the time, it averaged about 20%/hour. So at that rate the device would last for about 5 hours. But that is not average usage. My high usage of 3-4 hours with 18 hours standby is a better metric. And by all standards, this is excellent battery life for a device with an 1800mah battery without battery saving features engaged!
Oh, and my Doze usage last night was at 0.9%/hour

Yep, there is an Xposed mod for that! Disable su indicator (CM12) or in his all-in-one here.
I updated the Q&A. Thanks for asking that question!
@Easy_as_Pi_3.14 can I call you 22/7's?
You might want to include my video demonstrations of the wake algorithms in the FAQ
https://www.youtube.com/playlist?list=PLZ_n933bbFxFX7UUVjookMDEl1DYShSfg
(Sweep2Sleep and leniency are irrelevant to this kernel)
Also make a note that pocket detection makes wake controls not work when it's sufficiently dark
(My algorithm uses the light sensor data to check if it's in a pocket, YMMV on "sufficiently")
Also, btw, you might wanna make a list of recommended stable governors
IMO Uberdemand seems to be one of them
Further more I recommend putting that f2fs is only for data and cache (or maybe put a guide with how to convert to it)
Also, you are missing a few things in the kernel features that might be good to mention, and maybe explain what they are
Vibration Intensity, TCP Congestion Controls, KCAL, MDP Cooler Colors Control
I'll keep thinking of stuff to add to the FAQ
No doubt it will get bigger and bigger as time goes on :/

For short, call me @π.
Or, 355/113 will still get my attention.
Governor Explanations
I found this interesting thread about different governors, how they work and how to tweak them. Thought some might find it interesting:
@bryan2894, I noticed that the Show CPU usage in Developer options is blocked by SELinux.
I know it is silly, but here is the message:
Code:

I got a logcat/dmesg of the infamous touchkey derp.
I got it around 6:00.
Sorry about the "MP-Decision" spam.
Couldn't find it, but is there power menu options to add screenshot?

It is there already for me.
However, I found it easier to either use the key combo (volume first helps) or downloading an advanced file manager (my favorite), open Now On Tap (long-press Home in virtual keys, Menu or Search if I recall correctly on touchkeys), hit the share button, then use Save as.

Yeah idk about the logcat (not my forte), but I looked for some touchkey errors in kmsg:

EDIT: @Easy_as_Pi_3.14 What is the touchkey derp btw? I'm clueless about that, never heard of it.

Sweep2wake sometimes makes the touchkeys stop working.

Hmmm... I've had that before as well, but I do not recall having it on hercules (although I'm on CM11)
I had it on T769 (Candy 5.1)
So maybe it's a LP+ Issue?
Does anyone remember having it from before LP?
