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?

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.

thanks
Stay connected to wifi in bad mobile connection areas if possible, try a badass or conservative governor, only clock your phone to the power that it needs. You can always try apps like juice defender as well but I never cared for them. As far as undervolting, I would stay away from that unless you really know what you are doing.
I agree with above statement, under volting can cause reboots, force closes, ext. if not done correctly. It's a process that you have to know what is too much undervolt. How ever if the forcecloses or reboots are happening its a sign to under volt a little less. It's kind of a trial and error thing. If your up for it you can adjust to what you think is a good spot. It's all up to you. You will know by how your device is reacting. Best wishes !

Hello I usually don't post stuff like this, but whenever I see someone answer something, they are not telling the fact, but the myth. These myths are well known "solutions", but never work, since they're myths So I'm here to tell most of the myths that people are spreading... If you have any other myths that you'll like to talk about or if one of my myth is false, feel free to post about it . So without farther ado, lets get started
Task Killers: As much as this is obvious, people still uses it. So much, that it is annoying. Android handles apps and tasks well. However, there is an exception, and that is when the app constantly freezes or crashes and you need to restart it. If that's the case, there's a "Running Apps" section, where you can force close apps under system settings. So you won't need 3rd party Task Killers, EVER
Battery Calibration (Draining then fully charging): People thinks that this is good for your battery life, but it isn't. The only thing that this does is make the system read the battery percentage more accurate. Doing this once per month might help you improve read battery % better, but it isn't necessarily at all.
Wiping battery stat when the phone doesn't charge up to 100%: This myth is quite annoying. I dunno about other forums, but in Galaxy Nexus forum, quite a few people use this myth as a answer. Wiping battery stats DOES NOTHING to how system reads battery%.
Anti-Virus app: This is another myth that is obvious, but used by many people. You don't need anti-virus apps, unless you download a lot from untrusted source (4shared, because it is uploaded by people, not the company). If you know (And you SHOULD) what you're downloading, anti-virus is nothing.
Benchmark: People get so hyped about benchmark results... And I dunno why... It's just a number, I tell them. It wouldn't matter in daily usage, I tell them. But they do it anyways... Benchmarks are just numbers people. My Gnex can be as smooth and fast as GS3, but have a significant difference in benchmark tests.
Quad-core is faster than dual-core: While this isn't a myth, it isn't 100% correct either. You see, in daily usage, the phone only uses and needs a little bit of CPU power. For example, Facebook app doesn't use full 4 cores. That's just plain silly. However, when it comes to heavy gaming, yes, that 2-extra cores will help. But overall in daily usage, you're not gonna miss almost anything, because you have dual-core...
You need to clear cache and dalvik when updating/flashing a custom kernel: This is not true. I flash Franco kernel without clearing anything with NO problem.
You need to fix permission whenever you dirty flash: I don't hear that too often, but people still believes in it. Fixing permission isn't necessarily, unless you're experiencing random force close or crash.
Turn GPS off when not using: You do not need to do that at all. Phone only turns on the GPS when it needs to. For example, when you open map app, you'll see the GPS icon on the status bar, but when you exit out, you won't see it anymore. This means that the GPS radio is off. OFF. No need to waste your time turning it off and on.
Switch to 2G (Edge) when screen off to save battery: This is probably one of the biggest mistake people do to save battery. Yes, 2G does consume less battery than 3G, but constantly switching between them just burns the battery. It is just pointless if you ask me. Either stick with 3G, or stick with 2G. Constantly switching between them will be the worst choice.
Undervolt as much as you can to save battery: This is not true. Undervolting to a certain point can help you extend your battery life, but doing it too much will drain more battery instead of extending it. Also it makes the phone less stable, so make sure you know what you're doing and don't undervolt like crazy
iOS apps are more optimized than Android, and is more stable: This is part true but mainly not. Yes, dev only needs to worry about 2-3 screen size when making apps, which means that apps can be optimized for the screen size, but that doesn't mean much anyways... Also did you know that iOS apps crash more than Android? Now you know
iOS is better than Android : Lol wut?
Hope that cleared few things up. Again, if you got a myth of your own, feel free to post it in the thread!

Some interesting stuff
Sent from my SGH-T989 with Cyanogenmod 10 Alpha Power.
Quad core uses more battery than dual-core: this confusion comes from the intuition that "you'd need more power to run 4 of them". In fact, the results are closer to the opposite: on those rare occasions where multiple cores are used, they allow for faster processing (hence more sleep) and less intensive. Mostly, however, it just doesn't make a difference.

We should send these in to mytbusters so they can prove/disprove the facts. I personally use appkillers because the newer ones to make a difference on my underpowered P500. While these apps to start up, they consume less memory when started in the background and allows for faster start up once killed by the task manager.Android does have impressive memory management, but nothing is infallable.
Battery stats is just silly, if you keep charging till 90% then unplug, you can make it appear that your device can run for days on one charge, so that is very misleading.
Benchmarks are worth noting when it comes to gaming performance. On my device ICS definatly scores lower than gb, yet it runs smoother day to day. Playing games is tragic simply because the drivers are an issue on this device for ICS.
You dont need to clear the dalvik cache or normal cache to flash a kernel, the kernel modules are loaded at boot. The linux core behind android was designed this way. Clearing them when you flash to a different rom eg: AOKP to CM9 its a good idea to flash the cache since this could retain incompatible files between roms.
Myths arent annoying, people clinging to them for no reason is annoying.

I also had P500 and app killers did almost nothing at all... Maybe it's just me?
That's not what I've meant when I said about battery stat.. Some people's phone just doesn't simply charge all the way up to 100%. And others just tell them to clear battery stat, which does nothing...
Benchmarks ARE pointless in my opinion. I personally don't think that noting Benchmark scores are needed... Also they are not very accurate either. What I mean by that? Well, in real life (including gaming), even if you overclock, the performance isn't so huge. But in Benchmark scores, little overclock increases the score a lot.
I know myth itself isn't annoying, but people spread them. Like crazy. And that's what irks me
I'm fairly new to the XDA world, and all the "fun" that comes with it. I have been totally wrapped up in why my phone does what it does when it does it. A few times a week I'll run a dump file on Better Battery stats, run quadrant score while making a minor tweak on a governor or OC etc. Lately I have been addicted to this Cool Tool app, and thought I'd share. For all I know, you all may know all about it, but I don't see it on the threads here in SGS4G.
It's...... well.... COOL
It has alot of user friendly setting choices. It floats anywhere on your screen, while running your browser, or an app whatever. I keep mine up in the notification bar ( see screenshot). It does not appear on your lock screen.
Anyways, I have mine set to show CPU usage and freq. free ram, network traffic, battery temp, and my favorite- most resource intensive process. So while I open my browser and go to a website, I can watch what my phone is doing, how much cpu and at what point, and what %. Plus when I'm on my homescreen , I can see what resource it randomly draws from, system_server, events/0, android.email(and watch the network and cpu jump as my phone checks the email)
Could be one of many , but I like this one and you should check it out. Thoughts?
https://play.google.com/store/apps/...ult#?t=W251bGwsMSwxLDMsImRzLmNwdW92ZXJsYXkiXQ..
I haven't tried that one yet, thanks for the pointer!
Along with BetterBatteryStats, I've used Quick System Info Pro, as well as System Tuner (Pro) and Battery Monitor WIdget (Pro) for a long time and find them pretty valuable. The support from 3C on the last two has been beyond excellent. Looks like Cedric has merged his apps together as well.
Nice! I'm going to check those links out, Thanks. I'm definitely interested in your thoughts on Cool Tool, Jeff. Let me know after you've had a chance to go through it?

I'll try it for a bit, mainly because it is fun. It would have been handy for the CPU-speed overlay when I was tweaking the governor for Hefe Kernel, for sure.
Looks like it is likely a battery hog, especially that "top resource" feature - which more often than not is reporting ds.cpuoverlay - this app?
Posted from my SGS4G, thanks to Team Acid development
Yeah, ds CPU overlay is pertaining to this app. I haven't noticed a battery difference tho. The only place I see it in bbs is in services, and it sits very low, that's a dump file after a full day. And in stock battery stat after a full day running, it doesn't show on list of %(yet xda and and other minimal apps do) Good point tho. Don't want to cut ourselves off at the knees trying to save our shoelaces.

I suspect that it is running the standard utility "top" and parsing the output. That approach self-pollutes since you're always running when you "randomly" sample to see what is running. I don't know if that made sense, but...

I've installed it last night. My usual morning lag that I experience wasn't there so I believe there is some merit to what this mod is supposed to provide. I'll be tracking the battery life, as that's more important to me than a reboot once a day.
Yes I can also confirm that this app works. Even makes one of my slowest apps (amazon appstore) open much faster. Everything is a bit quicker.
My only concern is battery life, which I am going to be testing over the weekend. Loving the mod so far though.
I can verify this works well use to take close to a minut to load my xda ap lol. Not so any more. Also switching from app drawer to home screen, no lag. I used v6 supercharger for a while and i think that for now im just gonna use this. My phome is much more responsive than it use to be, especially when opening my settings menu. I will be paying attention to battery as well. Thanks for your work.
Edit. My cpu clock speed magically set it self to 1552. Dont ask me how that happened cuz i dont know. Now normally at this speed my phone would freeze. How do i know this? Cus its happened on more than one occasion. I dont overclock anymore because of it. I ran this app all day with no adverse effects. I cant say one way or another if this app works because i dont know when my phone was set to overclock. With the controversy surrounding this.... Im glad i didnt pay 1.50 for it or id feel like a really dumb***

From his post:
"So to be clear... IMNSHO, the recent entropy pool fad is bull****. The only users of /dev/random are libcrypto (used for cryptographic operations like SSL connections, ssh key generation, and so on), wpa_supplicant/hostapd (to generate WEP/WPA keys while in AP mode), and the libraries that generate random partition IDs when you do an ext2/3/4 format. None of those 3 users are in the path of app execution, so feeding random from urandom does nothing except make random... well... less random
The only conceivable reason some devices may feel faster is because by constantly polling the PRNG, it keeps the device's I/O in constant use (which in turn, depending on device, will make the CPU stick to higher clock frequencies to keep up and/or ramp up the IO scheduler)."
Yes it's bullish**. The whole explanation for this mod doesn't make sense and I just can't figure out how this would help at all. As RC said excellently, it would simply prevent I/O functions to go to sleep and keep your CPU higher. TL;DR : Raise your CPU clocks, change your I/O scheduler and you'll get better performances.
One more thing... I dont know when my phone was set to overclock but here are some interesting screen shots for you.
This is a 1500Mah stock battery. The original batter. I got with the phone over a year ago btw.
Something to cbew on i think. My phone has never run this well. Wtf?

Apparently everyone in that thread still thinks it works... I don't think they read Ricardo's post. Someone should keep posting it lol.

From his post:

Isn't faster performance accomplished by keeping the I/O constantly running and the CPU at higher clock speed than it would otherwise be?
Call me crazy but using this made my phone constantly stay in deep sleep! I've never, ever seen my phone stay asleep for so long and so consistently before.

My only concern is battery life, which I am going to be testing over the weekend. Loving the mod so far though.

I've been using this mod for a little over a week. While RC might be right about what this mod really is doing, my phone hasn't been snappier. As for battery life, I've lost about 10% more battery a day using this. I've got the Anker 2800mWh battery, and at the end of the day I'm usually sitting around 55-60% battery remaining. On hard use days I'd be around 30% battery remaining. Overall I'm still getting a full days use out of the phone.
If someone could suggest what scheduler I should use (instead of this mod) then I'd gladly try RC's suggestion and see if he is right as well.
