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.
AMOLED: Black wallpaper = Battery saving (experiment result)

great guide, will try this after I get some sleep!
I would recomend using manual control of display brightness!

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.

Added to recommendations, thank you.
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
on this screenshot, what contains the first line with priority of 100?

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?
There is no doubt that HTC One X is the most powerful phone on the market yet, despite it's stock of amazing hardware features it also has a few lacks. And on of the biggest perhaps is the short battery life, but with a few tricks and modifications it is possible to overcome that and so increase the battery life of the best phone yet.
Well I found 6 tricks and extras that can really increase your battery life up to 20%:
1. KILL APPS USING TASK MANAGER
Notice or not but there are a lot of apps and services running in the background of your phone that suck a lot of battery and most of them are apps that you wouldn't need so killing those processes can increase your battery life.
To kill apps you have to access the task manager:
Press home icon>all apps>search for task manager and launch it.
Now you have the option of killing separate apps (press X on the process you want to end) or just ending the all by touching the stop all button.
2. Closing open Apps
A great feature in htc one x is also that you switch between open apps but it can also take a lot of battery depending on how many Apps you =have open.
How to close open Apps:
Touch the recent app button (in right to the home button)> now swipe the open Apps (the ones you want to close) to the top.
3.Disable Transition Animation
Transition Animation also take a lot of batter since the require more ram and disabling them can also increase your ram therewith your overall system performance.
How to Disable Transition Animation:
Go Settings>Display & gestures> uncheck the Animation bar
4. External Battery
Well there is always an option of getting an external portable battery which is quit inexpensive and can double your battery life.
5.System directory Modification
Just a few weeks ago a member (mike1986) posted about a file or directory displacement made by HTC that caused the short battery life. And now you can correct it and you could boost you battery life by up to 20%.
LINK TO mike1986 POST
6.Battery Save App
A battery save app could also be a life save as you can monitor exactly how much on what you're spending and then configure power save modes using apps such as Easy Battery Saver.
You can also turn off services such as 3g/WiFi/GPS to save battery consumption advanced users can also scale the CPU and more system operation with such brilliant app as JuiceDefender - battery saver.
RECOMMENDED BATTERY SAVER APPS:
*JuiceDefender - battery saver* Free
JuiceDefender Ultimate Cost Money
Easy Battery Saver Free
Conclusion:
Following those six step should improve your battery life a lot and should therewith resolve the major issue with the HTC One X.

The biggest drain is the screen, so turn down the brightness.
Those other tips are probably more a placebo, and killing tasks is a bad idea on Android. Most of the apps are just loaded into memory but not actively running so not using power, and when your phone screen is off, nothing is running (unless you have a badly behaved application that is). Even if you have most of your memory empty of applications, those memory chips are still drawing the same power regardless, so it makes sense to keep applications in memory. Why? Because when you want to use the app again, the phone doesn't have to waste CPU cycles and power loading the application from the flash memory, then loading the applications saved state, so power is saved. If you never use the app again, and memory is short, it gets unloaded.
There is also the school of thought that if you shut down all background applications and so you lose functionality (background status updates, location services, push mail services, animations, weather displays etc), you then haven't got much of a smart phone!
The system directory modification related to an old version of the firmware, I doubt anyone is effect by that issue now.

Phil
It wouldn't effect your internal system apps

I do appreciate your replay but it only shows you those task that are running separately (not internal system apps) and if you kill them it does make a difference in the overall performance. And some operations like navigation running in the background continuously uses GPS and even Data constantly, so if you end it, it does make a difference.
You are right with the screen brightness, I thought about it and came to a conclusion to just leave it at auto because no one would like a dim display.
So it wouldn't completely turn off your data or calls or corrupt your system since you wouldn't terminate any internal system apps

+1
And also control 3G/WiFi/BT radios as and when needed , there are battery saver apps like Juice defender that intelligently turn off 3G and data connections.
Advanced users can also play around with custom kernels, CPU speed settings and Kernel governors, etc.. (can help with custom ROMs)
Thanks for the tip, I added it to it.
Actually agree with PhilipL.
Killing or managing tasks in Android is a placebo - and is likely to do more harm (in terms of battery life) than good. Plenty of articles if you google saying task managers are a bad idea.
However, managing screen brightness and background services will help enormously.

I have upgraded my Galaxy W to Jelly Bean using Custom Room (4.2.2) Cyanogenmod 10.1 alpha 2. maybe later alpha 3.
Everything runs well. but why my phone's battery drains so fast? and please help me HOW TO SOLVE IT AND MAKE IT LAST LONG TIME???
THANKS VERY MUCH....
Backup your apps, factory reset your phone. If battery drain problem persists, install Greenify or deep Sleep battery saver from Google Play to better manage battery resources.

when you just flashed the battery will definitely be shorter. Let it recharge for a few cycles before determining whether its good or bad battery life. Keep in mind however that even at full potential, the battery will not last for more than 2 days even at light usage.
if battery life is more important to you compared to "the newest OS" and whatever extra features it brings with it, then I highly recommend installing acro's CM9 RC2 (yes it is ICS) as the 2.x.x kernel is far better at battery life than 3.x.x (i'm currently testing it and I can already feel the difference! I believe I can reach 2.5 days at modest usage but I will have to update you on that after my first few discharge cycle for battery to reach potential after flashing new rom). I do, however notice a few annoyances with RC2 (not sure if its really the ROM, or the custom kernel i'm using, or Nova Launcher is to be blamed), so if it continues to bug me I may just switch back out to latest ICS =p.
If keeping with the latest JB is important for u, best thing you could do is download a custom kernel for it that supports UV(undervolting), then get IncrediControl and tune down your UV based on some voltage tables you can find in FAQ. This alone won't bring you a HUGE improvement in battery life but its definitely an observable difference. On top of UV, try to UC(underclock) your CPU to 1GHz. Most daily functions, apps and games (depending on how intensive it is) will work perfectly smooth even at 1GHz. IMO, the most important point of UCing is you will notice a very significant difference in the heat of your battery (ie backcover of your phone). Heat is generally bad for the battery (shorter life + faster draining) so UC is definitely a good thing to do =). Of course, on top of all those, get greenify and wakelock detector(WLD) from market to control your not-so-frequently-used apps. Use WLD to track down what is keeping your phone awake (hence drain more battery) and use greenify to hibernate all the not-so-frequently-used apps you have (example of things you DON'T want to greenify: whatsapp and gmail as you don't want to kill these 2 programs when you lock your screen. You want to continue receiving whatsapp messages and gmail when you locked your screen right? XD! Examples of things you SHOULD greenify: games, music player. Maybe some of the games or other apps may keep a background service active, secretly using your battery even though the last time you used it was 2 days ago!)
Finally, if your wonder is about 1-1.5 years old, chances are your battery is already bloated (perhaps you can feel your battery through the backcover of your phone even!) A bloated battery is a dangerous and short-capacity battery. Even with the best rom you may only push through a day from 100-0%. If your battery still looks fine but your phone is nearing its birthday, go ahead and do some online shopping (ebay or local equivalent, like malaysia we have Lelong.com.my) and get a battery for your phone. Its usually much cheaper than buying from telephone shops.
EDIT: Adding on to all of that, choosing a good governor+i/o scheduler combo is important as well. If our phone is similar with the S+, smartassv2+sio(i've used this, its quite smooth and battery is good) OR OnDemand+noop is thought to be very good in terms of battery life and responsiveness. Lulzactive is also very good but its not so easy to tune it so i usually would stay away from it. Do bear in mind that although the former 2 combo is good, it still highly depends on how you use your phone so there will not be a universally best governor+io combo. Both of those suggested by me are supposingly best in responsiveness as well as deepsleep battery conserving (only if the assumption that our roms work the same as the roms tested in S+, which MAY NOT be true).
TL;DR? try smartassv2+sio (u may change this using IncrediControl, get from playstore). Then if you are not satisfied with your current performance/battery life, you may continue experimenting by changing governor and i/o scheduler one at a time. If you are doing the testing, make sure to have some way to record your tests if not you will 100% be deceived by placebo!(with actual numbers you will clearly see whether your feeling is placebo or if there really is an improvement)
I'm having some seeeeerious battery issues with alpha3. With just 15 minutes screen usage in a day, battery settings says my screen used up more than 20% of the battery! This just for consulting the time and the weather.

that 20% is not actually the 20% of the battery juice. It is 20% of whatever amount of battery is drained due to the display being ON. Like if your battery is used from 100% to 90%, then only 2% is used by the display.
I am not sure if I could explain what I mean.
EDIT: Hmmm maybe I misunderstood what you said... If that is the case, disregard.
And also my galaxy W will use all of its battery charge when the display is constantly ON for about 3-5 hours.
Actually, I've figured out what it was. It was Google Now. Chewing away at the battery without saying a word anywhere in the battery screen. I am now back to my old 3 days battery.
you need to install cpu spay from google play and you need look deep sleep time.
this reaction is typical if your coming from a stock or at least cm9.
there has been a lot of arguments about battery life of cm10 and above.
in my opinion, there really is a difference, i mean cm10+ drains battery faster.
and the reason being is of course the features there is in cm10++.
if you're after battery life, stay with stock or cm9 (for now).
but if you feel like your in with cm10+ and you don't want to go back like me, then may want to try these tricks:
1) using Titanium Backup, freeze the apps that you don't really use.
- in my phone i froze pico tts, voice search, talk back, etc. (i even froze google search )
2) i use an app called "autostarts", it can disable auto starting of app including those of the system.
- in my phone, i disabled google maps in every activity. ex. after startup, connectivity changed, wifi connected, widget updating
3) disable system settings which also contribute to battery draining.
- disable location service when your not using it
- disable automatic backup/restore
- disable haptic feedback
- disable autosync
- disable the top battery drainers when not in use (wifi, mobile data, gps, bluetooth)
- and many more just explore
4) do not use so many widgets (my home screen has 0 widget)
5) do not use live wallpaper
6) charge only using the original charger, not from other phone/brand, not from a usb port
- the best way to charge is to avoid using the phone until it's fully charged
7) finally, install only apps that you really need. just keep a backup of your not so often used apps and install only when you need them
If you think about it, everything i wrote above contradicts with the original concept of Android.
But that's life, sometimes you have to trade something in order to achieve another.
Our phone was baked as Gingerbread, now we want to make it taste like Jellybean.
We have all the ingredients, but we don't have a jelly bean pan to make the candy molds.
So we improvise, we work around, we do some shortcuts, we make alternatives, certainly it will cost something.

I AM NOT RESPONSIBLE FOR ANY NEGATIVE IMPACTS OR CONSEQUENCES ON YOUR PHONE IF YOU SO CHOOSE TO USE THESE TIPS.
I've created a couple threads on the ZTE U950 and LG G2, and one problem is the battery life. The battery cannot come out of these devices and thus we cannot combat this with a bulkier, beefier replacement for heavy usage. Charging constantly is something I try to avoid, so these are a few simple tips that can help optimize your battery life (and that APPLY to ANY PHONE):
TIPS
BATTERY
1a) Buy and download CPU Sleeper (root required). There are two versions, one for dual-cores, and the other for quad-cores. Essentially, when a phone is "sleeping", it is actually still running all its cores, helping drain battery faster. This app turns off all but one core when it is "sleeping" so that your battery is not drained nearly as fast.
BATTERY
1b) To take this step a bit further you can download a free app called Multicore CPU Control. In this app you can control your other cores. You can setup profiles to turn on or off cores, and setup each core with different governors. On my LG G2, I setup a profile to only have one core running at 960MHz (2.2GHz originally) after using the steps from below. If you plan to only run one core, then you do not need to buy CPU Sleeper.
NOTES ON 1b: Multicore CPU Control is the name when installed, it is called CPU Performance Control Free on the Google Play Store (either name will work on Google Play). The program needs to be turned on after each boot. When first setting up a profile save it and edit it in order to manipulate the other cores available. The app does not always apply a profile even if it has already been selected. To turn on a profile, click on the profile desired and go to the CPU Monitor tab to check if it has been applied. If not, repeat the process until it does (it usually takes me about 3 times at most).
BATTERY/RAM
2) Download Greenify (root required), a great free app! Sometimes a user does not have a ROM with a kill all button, so pesky apps just stay on without consent. This app allows a user to turn off any app that may want to run in your background, and even shows you which apps are currently running. Apps like Facebook, Talkatone, etc. can all be stopped even if your "task killer" supposedly took care of them.
BATTERY
3a) Wakelock Detector-Save Battery is a free app that checks for apps that continue to work while the phone is "asleep". While Greenify will display the most troublesome apps, this app will help discover any other apps that are running without consent.
BATTERY/RAM
3b) If Greenify does not show the apps discovered in Wakelock Detector-Save Battery, then download Disable Services (root required). This free app allows a user to disable an entire service, or just parts of a service that are bothersome. Click on a service/app to find out what other services accompany it. Read the accompanying services and discern whether or not the service is needed. A good place to start in this app is to check any service/app that has a blue number next to it.
EXAMPLE 3b: I use the Outlook app a lot, but sometimes it gets annoying with updates for insignificant email. I can open Wakelock Detector-Save Battery and click the Outlook app. I turn off "AppWidgetUpdateService" to disable Outlook email updates. Not all services have obvious names, so be careful on system apps if performing trial-and-error.
BATTERY/RAM
3) Buy and download BetterBatteryStats (CPU Spy Reborn/Plus is FREE and only shows CPU states). This app tells me what CPU States are used the most often and is what I download first before my next step. A user can also determine battery-draining apps and turn those off. If turning off those apps is not possible through Settings>Apps just Greenify them!
BATTERY
4) Underclocking. This is an amazing step for saving battery! If you have ran BetterBatteryStats for at least a day, this will come in handy and is highly recommended. You can use numerous programs like SetCPU or Voltage Control to set the clock of the CPU. The key is to find a point that will still be responsive, yet lower than the maximum.
EXAMPLE 4: For this example I will be using my ZTE U950 and Voltage Control. According to BetterBatteryStats, my most used clock was at 1.2GHz and 860MHz. I left my minimum clock at the lowest possible setting, while my maximum clock I changed to 860MHz. I ran this for a few days and saw a noticeable difference in battery life. Another important part to this if choosing the right I/O Scheduler and CPU Governor. I found the default I/O Schedule ("cfq") to perform the best, despite "noop" being good for sluggish memory. "Powersave" is a good Governor at stock CPU speeds, but it will not get a user the savings of power that a step like this will. I tested with this Governor with this step and got horrible reaction times and would often need to restart the phone. The best results I have are with "ondemand" and "interactive". I am currently using "interactive" with a maximum clock of 475MHz! I arrived at that number after checking my BetterBatteryStats while running at 860MHz and found that to be the next most used clock. Now my battery is lasting about twice as long as it normally did! My phone's response time is a bit slower at this low clock speed, but that can combated...
BATTERY/RAM/SPEED
4b) (IF YOU HAVE INIT.D SKIP TO STEP 4c) My LG G2 is underclocked to 960MHz, as noted in step 1b. I am saving quite a bit of battery, but the UI response can lag a lot at times. The use of boot scripts can be helpful to compensate for this. However, my LG G2 does not have init.d support. There are numerous threads that explain how to get init.d support for a lacking Android phone. The simplest method is to install an app from Google Play. I use one called Init.d-Installer just because it forces the phone to reboot once it has installed; others do not seem to do anything to inform a user if they have received init.d support
BATTERY/RAM/SPEED
4c) Download a script called V6 SuperCharger. The thread may seem daunting, but it is fairly easy to install. Download the newest PDF and change it to TXT. Ensure you have init.d support, BusyBox installed (also in the thread if needed), and SuperSU. Run the script in a free app like SManager with SU permissions and follow the instructions. This script gives the ability to enhance speed and power. I install this in order to ensure my UI stays responsive, and LG G2 runs almost at stock speeds (alongside all my other enhancements)!
BATTERY
5) Undervolting (root required/custom kernel required). This is also a great way to save battery. I decrease the voltage in steps of 25 and test from there. If I find no quirks, I leave it. If I find sluggishness or have random phone reboots, I increase by increments of 25 (or 12.5) until I find something stable.
Most phones will not allow undervolting without a custom kernel. To see whether a phone can undervolt or not download, Sytem Tuner. There is a free and paid (Pro) version of this app, but the free one should be sufficient for what we want to do. After installing, open the app and click on the Voltage settings tile on the left-lower side of the screen. All the phone's CPU MHz steps and the amount of voltage applied to each step can be viewed. At the bottom of the screen are buttons to increase or decrease voltage in 12.5 increments (which will apply to all steps). If the -12.5 button is clicked and the values of all the steps drop, then a phone can undervolt. Additionally, System Tuner allows a phone to manually apply undervolting to each step if wanted.
To test undervolting, just push the decrease button until the phone freezes up. There is no harm to your phone or CPU as neither are being overpowered (just the opposite), and a reboot after freezing will reset the phone to default voltage settings. A - 75MHz drop is normal for a phone while remaining stable; and in a lot of cases -100MHz is achievable.
NOTE: Tips #4 & #5 also can be applied to GPUs.
NOTE 2: One thing that should be mentioned is to be careful about putting more than one app that controls CPU clocks. They can read differently and trump the other when used in combination. Instead, install and use one at a time to get more accurate readings. The same should apply to undervolting apps.
BATTERY/RAM
6) A user can change the Dalvik cache a bit to see if that helps optimize RAM, and possibly battery. I did quite a few tests for these to see how they performed. I think the only reason I noticed any changes immediately is because of how far underclocked my CPU is. Anyways, the best results I was able to get with my ZTE U950 was as follows:
124m - dalvik.vm.heapsize (2nd one, not 1st)
8m - dalvik.vm.heapstartsize
For other phones, these are the items to trial-and-error with:
davilk.vm.heapsize (may be more than one at different values)
davilk.vm.heapstartsize
davilk.vm.heapgrowthlimit (may be more than one at different values)
A user can change these settings by downloading an app like Build.Prop from Google Play. I did notice my battery seemed to drain slower with these changed. The RAM was the best optimized for the self-made tests I performed and was nearly the best in all the tests I had ran. A user may or may not notice any differences unless they multitask a lot.

7) All other well-known methods apply as well:
A. Battery Saver apps/settings
B. Battery Calibration apps
C. Refrain from the use of widgets
D. Automatic Brightness apps/settings
E. Small Screen Times before Screen Sleep
F. Turn Off WiFi and/or Data when not needed
G. Task Killers apps/settings
I'm trying to improve the performance, battery life, and stability of my phone. A few days ago, I found out about Android Tweaker 2. I use the auto tweaker and tasker profile features and am wondering if they would conflict with Greenify if I were to install it.
My auto tweaker is set to balance performance with battery life, and to only use safe tweaks. My tasker profile is set to hard (aggressive RAM management values) with persistence on boot. Note that "tasker profile" here has nothing to do with the Tasker automation app. By "tasker profile," Android Tweaker means multitasking profile.
I have not changed anything in the system tweaker, OTA tweaker, app manager, smart actions, or multitasking sections.
Would this setup conflict with Greenify, or would I probably be okay using both? I'd like to try Greenify so that I can increase my battery life. Thank you.
Well, I went ahead and did it (installed Greenify and set it up) and as far as I can tell my phone is working fine. It's much less laggy, and so far Greenify has cut my battery usage in half. That's with heavy usage too- a lot of screen on time tweaking things.
Between Android Tweaker, Greenify, Nova Launcher (more lightweight than Trebuchet), zipaligned apps, smartassv2, 1.3GHz overclock, some Xposed modules, uninstallation of unused system apps and custom ROM apps, and better use of widgets and quick settings, I think I may have made my phone far less frustrating than it use to be. Time will tell, but I may actually be able to enjoy it now. Maybe I don't need new phone after all.
I wouldn't think so. Greenifys sole purpose is to minimize background data use of apps when in idle. I've ran both exposed and android tweaker 2 which is the new version and didn't see any issues until android tweaker 2 started force closing with certain tweaks but with bit still being in the beta stage that's normal for a few issues. Only issues u may probably have will be in exposed itself cuz the sources have only been tested on 4.2 ROMs even tho they will work on any jellybean ROM. Hope this was of some help to you and if so feel free to hit the thanks button
