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.

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?

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.

How to save battery on nexus S

Hello there..
i just rooted my nexus S 9020T..i flashed CyanogenMod-7-08312011-NIGHTLY-NS,Build number GRJ90,Android version 2.3.5
my problem is the battery keep draining faster..
fully charged at 7.00AM..10% at 4.00PM
i using Juice defender ultimate (said longer my battery 1.5x)
please help me...

Juice defender is a waste IMO. You could try an undervolted kernel like matr1x or Trinity.

I suggest teuv kernel by Trinity, best battery life I've seen.
The nexus is a battery hog, especially with all kinds of background apps people have like whatsapp and facebook. If you get Trinity, follow instructions and you wont news any outside monitoring app as the kernel is very good about ram and CPU allotment

any other tips how to save battery longer??

Any further tips after a new kernel and rom would be cutting on the use of the phone and are therefore meh. I want to use the phone, not use it less.

So Trinity is better than Netarchy???, what about Pete #5 which is built in Formels MIUI, so far this is the best Rom I have tried on my NS, stable and fast+good battery compared to the others, also I have my phone OC at 1.2G via Setcpu.

Set wifi sleep policy to never.
Turn off auto brightness
Turn off sync and just refresh your gmail manually when you need to and refresh your contacts from time to time. You still get app updates from the market with sync turned off.
Go through all your apps that update regularly (facespace, twitter etc.) and reduce the sync frequency to something that is acceptable for you. I don't need my twitter updating every 15 minutes and can just manually sync whenever I want.
EDIT: Turn off NFC.
... and buy one or two of these: http://www.amazon.com/Samsung-1440m...TUEW/ref=sr_1_1?ie=UTF8&qid=1316132022&sr=8-1
Make sure to condition them properly - it really makes a difference.

Wifi Sleep Policy to never fixed alot of my battery issues

Turning off NFC will do nothing as NFC does only consume power (like GPS) when used.

PROTIP: Stop using the phone so much. None of these tips are going to do squat if you're using the screen and wifi/3G all day.
Trust me on this. I easily get 12+ hours of use with battery to spare (usually around 30-40%) with the following usage:
NOTE: Matr1x Kernel with the stock undervolting settings, and TSM Pool Party ROM running on top.
The screen is on (a little over 1/4 brightness) with wifi/3g blasting, surfing bright white web pages for about 2-3 hours total. I may play 30 minutes of Furious Neornithes D), screw around on the market for a few minutes, check FB updates, etc. I also probably take/make about 10 short phone calls and send/receive about 50 texts. The remaining time, the phone sits in standby.
Not bad, considering the phone is beefier than most home computers from 10 years ago. Also worth noting: The battery scale isn't the most accurate thing in the world. Battery percentage drops off sharply up until about 60%, where it seems to level off.

So what's the best kernel to use???, Trinity or Trinity UV?, Netarchy?, Matrix?, is not only about the battery but also stability, doesn't matter if u can make ur phone last forever if u can't use BT while browsing cause the thing crashes so u either have to use one or the other.

As this is the save battery thread, there's only one answer: lowest voltage trinity kernel.

[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! ;-)

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?
Sent from my SAMSUNG-SGH-I997 using XDA App

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.

[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.

One Power Guard Battery

Getting better battery life is a struggle most mobile device users will have for the foreseeable future. Even if advanced batteries are released that give users two days of heavy use, there will naturally be a script, an application, and a kernel tweak to improve this figure further. As batteries get better, so do battery applications. Now, a new tool has been released that’s looking to be the best.
The application is called One Power Guard. Made by XDA Forum Member fonter, it is designed for rooted and custom ROM users. It brings an all-in-one approach to battery life and phone tweaking. You can adjust pretty much anything, including the I/O scheduler, CPU governor, CPU over- or under-clocking, settings tweaks, and more. There are also six modes you can choose from that tweak your phone for you. They include:
AI Mode: It intelligently adjusts cpu frequency and optimizes kernel to greatly extend battery time according to system loading.
Powersave Mode: It runs devices under low frequency to extend standby time.
Game/Video Mode: It provides flow game and video experience while offering satisfactory power-saving strategy.
Call Mode: It powers up the core function of phone conservation. For business persons trapping by phone.
Standby Mode: It lowers system frequency and prolongs stand-by time to the extreme. For sleepers and dreamers.
Custom Mode: It indulges pros to customize cpu frequence, scheduling and io adjustment, and to choose parameters of their own.
It’s a really nice application for those who don’t want to re-tweak their phone after every ROM flash and those who don’t know how to tweak their phones manually. For additional information on how each mode works and download links, check out the original thread.
You can try One Power Guard, Download from onexuan.com

trying this out, we'll see how well it does compared to the others

OK app works much better than anyone I've tried for this matter, doesn't help too too much but it does make a little bit of difference, also this should be obvious but it does slow the system down a bit, and i also had some conflicts with it changing kernel values but I'd rate it a 3.5 out of 5 for what it does though when compared to other apps four the same thing out would be a 4.5-5 not a full 5 because there has to be done room for improvement

I'd have to give this probably a 3.5 as well, could be better with a widget for one thing. I used ai most of the time, but when I went to custom mode and changed the frequency for max to 1200, it didn't change it and left it at 200. It did provide a good bit of information though!

Slowed my phone
I unistalled this. My phone became almost useless. It was so slow and nearly unresponsive.

Seems to be working pretty good on mine. Definitely added about 12hrs to my extended battery.
