Battery Optimization

So, with all this talk of over clocked/undervolt kernals, smartass gov, setcpu, and juicedefender, I was wondering what the definitive way to optimize battery is (without doing a bump charge).
I dont need any crazy quadrant scores or anything. I just need a phone that can play the occasional game here and there, surf the web, and text message; all while being lag free.
I have done all the "normal" battery savings like turning off 4g (live in 3g only area anyways), backlight lowered, no live wallpaper, ect. My question is what is the "best" method for squeezing out the most juice?
I know there are MANY opinions as to what the best is, but I thought I would poll the masses here and get their 2 cents on the subject.

Well, I pay attention to my current widget. There's certain areas where battery drain is a problem with mobile data turned on. I turn off mobile data when I'm in those areas. Being mindful of that has been the #1 battery saver for me. In fact, I even run with automatic brightness instead of a very low brightness setting and I get better battery life now than before.

I seem to get better battery on lower, mainly because when I do auto, it goes full blast most of the time, and likes to switch about 20 times from high to low while im texting.
My main question here is out of the more detailed methods (new kernal, setcpu, ect.) works best. I know kernals seem to give better performance and battery to some, but I read some of the kernal builds have some hiccups still.
Just wondering what you guys have found is best and most stable of the "detailed" methods.

Of course, I do as well. I was just saying that turning off mobile data in the areas that tend to cause my phone to draw 700+mA saves a significant more amount of power than turning the screen to low.
I'm currently planning to try out setting Tasker to automatically turn off mobile data when connected to problematic towers.

Well, I'm running BAMF 1.3 with the smartass governor. It saves quite a bit of power and has very little setup (you don't have to set up profiles with setcpu).
The newest Tasker adds CPU frequency control support... it doesn't currently work on the ROM I'm running ... but I'd imagine when we get CM7, it'll work. Presumably you could use that to always scale down the CPU until you open up specific apps that benefit from additional clockspeed. It could save a bit of power.

NEW APP in the market - LTE OnOff - switches phone from 4G to 3G to save batt.

I purchased Tasker a while back just because it sounds cool, but I've never really found useful tasks to run with it for how I use my device; still looking though!
Yours sounds ideal for some areas I go to. Please remember to share the Tasker profile you come up with for that functionality.
Thanks!

Hello guys, Im coming over from the eris/custom rom to TB this past week. I was wondering what kind of life you are experiencing with the custom roms here like BAMF. I haven't rooted it yet but am planning to since the current battery life is not acceptable in my daily life. I love the phone but need to figure out if I can keep it or not by helping my battery life. I have 4g disabled since it is not even avail in my area yet but still only getting 6-7 hrs. Thanks for any help, opinions, or redirects.

hehe...
This is great. Reminds me of hypermiling with my car/hybrid to get the most gas out of it. Well...it's about that time again with fuel costs going up.
So what is the equivalent term of hypermiling for handhelds/phones? Hyper-???

Never mind. I guess the thread title was fine "battery optimization". But those gas/hybrid nerds (like me) love using the term hypermiling.

I like using setcpu profiles or custom kernels

6-7 hours? Jeez. I have a fairly stock rom (perfect storm, which is more or less just bloat free) with 4G off, backlight to around 35%, only one gps running - the google one for the HTC weather, I use wifi when at home, I have nothing that pushes except my main gmail and the htc weather, do texting all day, and about an hour of internet a day. With this setup after 16 hours I have always had over 50% battery.
How many things do you have pushing data? Facebook or twitter? And if so what is the interval? Also, how much on the net are you, and how often do you game?

Battery optimization is just a term I figured work, but hypermiling sounds pretty sexy Increases your battery mileage of course!

I'm using Superpower to disable data connection when the screen off. Seems to be working well.

Never game, 2 gmail accounts, fb few times a day, no twitter, net 2-3 times a day. This is stock sense on the phone though. Thats why I was looking into the dif roms to see what battery life was like with dif kernel on it. I will prob root and toss a rom on there to see if it gets me better life (which im sure it will), but considering waiting until the 16th (rumor out that fairly big update coming and want to see if that may help at all).

This really is the best way to save battery at the moment.

I made my battery last the whole day after I installed Automatic Task Killer from the market. It kills selected processes as long as the screen is off. I get home after 9 hours at work and I still have ~40% battery left. Before I installed Automatic Task Killer my TB was dead after 9 hours.
There is so much random bloatware on the TB from vzw that it eats the battery fast. I just need to root I had a Eris on a custom ROM before the TB and I could go 2 days easy without a charge.
This seems to be a fix for the time being. Too bad there is no way for developers to make a one click root like on the Eris. I will have to bite the bullet and do it the old fashioned way.

Can you reference where you heard this "April 16th update" rumor? I'd like to read about this one and see the credibility behind it.

[Q] battery drainage for infuse 4g

im having issue with my battery life can anybody give me any advice??

Can you elaborate on what kind of battery life you are getting, what kind of usage, and types of activities like bluetooth, wifi, gps usage etc.. Also, let us know if your stock, or custom rom with custom kernel etc..
I just posted some suggestions in another thread, follow link below and read my suggestions on 3rd post.
http://forum.xda-developers.com/showthread.php?t=1339479
This is a good place to start. In general though you should be disabling radio's and features that you don't need. Think of it in terms of how you conserve, or should be conserving energy at home. You probably have about a hundred different appliances or light switches that you can turn on at home.. but just because you have them all doesn't mean they should all be on at once! ;-)

i am running the ROM 2.3.5Doctorz RomV8.1 with an infusion 1.1 kernal and i moderatley use my phone and am seeing the battery life of some other people and mines just doesn't compare

Things you can try!
Download CPUSpy from the Market. Check to see if your phone is even going into a deep sleep, If you notice heavy cpu usage then you need to find out exactly which app is causing it and delete it. Widgits and other gizmos that eat ram will also cause bad battery life, try turning sync off, turn data off if your not using it, turn GPS off if your not using it. If you just installed that rom, you need to give it a few days of charge and discharging it completely before the battery can settle in and give you accurate results.
Edit: JuiceDefender is not an option, Recently deleted it to see that I gained back 2% battery after unistalling. Goes to show you battery saver apps don't work.

I had the same issue with mine as well... Charged completely last night before going to bed disabled wifi gps bt etc... Woke up this morning with 38%... I was blown away.... Since have odin back to till i get home to mess with it.... I know everyone has there oww personal preference and i respect that... You have aby suggestions on rom "with working bt", kernal, modem etc... And tweaks/ non tweeks that will get good use?

Well my experience is Juice defender works very well...especially if you understand how it works and what it is doing. But in your case you are probably have other unrelated issues.
Cpuspy might point you in the right direction but it could be as simple as looking at your settings: applications : running and see if any are continuously "restarting". On new roms I typically see what's running (i.e. sns is problem app for myself) and if I don't like it then use TitaniumBackup to freeze the apps. That combined with juice significantly increases my Infuse's battery life on the various ROMs I've used.

I'm running the original stock Froyo 2.2 UCKH1, I've been on battery for 1day and 17 hours before going dead. Check your apps, check cpu usage. Otherwise you got a bad battery.

Glad your getting things straightened out, Check out an app called Android Assistant from the Market. Gives a lot of details about your battery, what processes are running and allows you to kill them, also allows certain apps not to run when you boot the phone, cleans cache and history, allows you to move apps to SD, it's got a bunch of tools you may find useful and best of all its free and uses absolutely no battery as for it doesn't run as a service or hang in the background.

Are you sure it's not a kernel issue?

[Q] Any tips on saving battery on Sensation ?

So i just got a deal for a cheap Sensation and decided to give it a try. After a few days, i really like the Sense UI + ICS but find the battery is pretty bad compare to my GS2.
The Sensation drains about 8% overnight while the gs2 drains 2-3% overnight, both with nothing on. When playing music (doing nothing else,screen off) the battery drains a whopping 5%/h. while i dont think the gs2 would drain more than 1%/h just playing music. I thought the battery life on both phones should be more or less the same given the same specs and battery capacity (1650 vs 1520).
To be more specific, my ROM is ARHD 6.5.0 ICS, i havent installed any new app yet, i have the follwing widgets on : email, messages, weather, contact, task, music. I'm not sure if the drainage is coming from those widgets.
One more question, is there any way to quickly change brightness ? (like sliding the status bar as with the gs2). Auto brightness may be draining more battery but going through setting->display->brightness every single time is painful.
Any tips would be appreciated. Thank you.

something like this should do im not sure havent seen any other kernel for sensetion 3.32 base UV'ed

Juice Defender is a good option to test out, even using default settings it's pretty good with helping battery usage/drain.
Otherwise ARHD is using Sebastian's kernel at this point and you have the choice of using the 1.2 or OC'd 1.5 Ghz speed when flashing. If you're concerned you can use the 1.2 version or flash the 1.5 and just set the clock speed using something like SetCPU, available here on XDA, or System Tuner, from the Market.
As far as I know right now, the kernels are not allowing UV because the official source hasn't been released yet. Once source is released/obtained then things like UV and other deeper optimizations can be done by the awesome kernel developers here.

So you have finally made your choice in choosing between HTC Sensation and Samsung Galaxy S II? Found yourself having to recharge your new Android device every 8hours? You’re not alone. Some users reported to have a poor battery performance for their Android phones. Older device ranging from HTC Desire, Motorola Droid, Samsung Galaxy S, Sony Ericsson Xperia X10 to the latest dual-core Android phones; LG Optimus 2x, Motorla Atrix, HTC Sensation, and Samsung Galaxy S II, are not sparred with complains of poor battery life. However, Android itself is not a power hogger, or call it battery juice sucker if you like. Many users were able to get their Android device up and running in a single charge up to 3 days(gosh I missed the good old Nokia 3310-era).There are many factors in leading to poor battery life. The very main reasons are the display and unnecessarily turned on features, which some users don’t have a clue in turning it off. If you are happened to be one of the Android users not happy of the current battery performance, or you simply just want to improve the extra mileage of your Android device’s battery performance, here are some tips in improving the battery life of your Android phone.

because its for sound boost only, idk what u seek but it wont handle your volume into time but just boost it, i also noticed it doesnt work on sense but will on nonsense roms

Battery problems absolutely solved with "3g off" widget, on the market. I don't need anything more than basic phone and sms for hours at a time so I just hit the widget. Takes a few seconds to sync latest mail when it comes back on but less time than that to just find a 4g link. Great when I'm at the ofc where my mail gets pushed to my laptop anyway.
Very useful also in a weak-signal area, stops drain due to signal-search.
Juice Defender is very good for battery life but this solution is even better although the widget does require manual intervention when the screen comes back up. I use both. Possibly JD paid app automates the whole process.

First of Apex is correct, this should be in Q&A. But since it is asked, we'll try to answer.
A little more info about the phone would be helpful in getting an answer to you. Is your phone root? If so, is it running a custom ROM, and what mods have been done? Is it running ICS or GB?
A good app to find a battery drain is BetterBatteryStats.
I also second the SuperCharged script as a battery saver (in most cases). It is quite easy to setup once you understand how to do it. Also be sure to read all of the first two posts in the thread. You will need to be rooted to run the script.
Hope this helps and hope we can get you squared away.

Seeing as how you have OS Monitor installed to try and track down the cause for the drastic discharge in battery, I have to assume that your wife's Atrix 2 is not rooted, and you are likely on 2.3.6, since the only way you would be on ICS is by obtaining root access and flashing either of the two leaked versions of 4.0.4. That said, we need to know a little about the 'usage' of the battery that is causing the sudden discharge. If you can go and get a screen capture (with another camera phone or otherwise) and post the screen shot of the battery statistics from navigating to Settings or System Settings>Battery>and show what the linear graph can tell us about the usage of the battery. How long has this issue been occurring? If not long, comparatively to the length you've owned the device, I'd rule out hardware issues. Likely, you have a rogue app, or something else like a kernel or power wakelock that is causing constant drastic discharge rates. I've written up a rather extensive guide for getting the most out of your battery (as seen below in my signature), and you can have a look at that to see if any -or all- of those measures are helpful. It sounds like the battery itself could also be the culprit, but again, without further information to go off of, it's so hard to pinpoint...

Hey guys, was wondering if there was an app I could use to control the CPU speed and cores of my galaxy s5. Any app I use seems to reset itself upon exit, and I have not been able to get clock speeds to stick once, despite forcing it to set on boot. Any help would be appreciated, I keep losing close to 1% every minute of usage. Thanks.

There are a lot of factors involved in the Battery of your device. Keep in mind that not all devices act the same. Also the way you use your device. What apps you have. Cell reception. How often you check your Email. How often your apps sync. These are just some of the factors involved in how long your battery will last on any given charge. With that in mind, yes, you can increase the Battery life on your device. Are you Rooted ? What Rom ? What Kernel ? Which Android version are you on currently ? What Recovery are you using ? I know these sound like a lot of questions. But it's much easier to help you with more information.
Lastly this really should be posted in the Q/A section. It will get faster responses there.

I'm on aosp lollipop, I use greenify for my apps, keep app count to minimum. I know what can be done to manage battery, but all I really need is an app, or method to manually control the CPU of this phone. Like I said, any way I try doesn't allow CPU speeds I choose to stick.

I'm not familiar with AOSP, but are you using a kernel that supports changing the cpu speeds?
