CPU Tuner - Battery Saver

Guys, look that...it seems to be nice...I installed and im still testing...Some users said this app helps to increase the battery life in almost 25%....I liked the UI also, is very very nice...
Im going to test...

My kernel does not allow me to change the frequency....
Need to change...By the way...I notice the phone become a quiet slow with this app...

same here, I cannot change settings, however, I do not find apps running slower or the whole sys response got worse

There is no way a cpu tweak can save you anywhere near 25% ...
The screen uses about 80-95% of the battery even with a 1.2ghz overclock cpu doesn't make near that much of a difference...

It's funny because I thought the screen was a new technology super battery-saver lol and it's clearly not
However, the Wave who have 0.7 smaller screen but the same technology have a battery like 3x times better.
the difference? the os. I'm pretty sure the problem comes from the Android and nothing else.

I would second android being the culprit....considering most of us are running leaked 2.2 battery management has not been fully implemented. I had great battery life on jh3 and jh7...... but I would never go back to eclair to get better battery life. The epic is starting to get.official froyo and I read that Canada should start seeing froyo this week......all we need is for att to get on the ball and Samsung to release their source code

hey guys,
does anyone have an older version of this app. It used to work great for me, but with the latest updates it has not performed as well.
thanks.

Actually the 1.0.1 version is really good. Here is a guide how to use it:

I haven't tried it yet. But if I understand what it is by the name I don't think it will help that much. Android OS already changes frequency based upon usage. You can see these percentages in the Android System Information app. For example, mine reads as follows:
1000.0 MHz 3.19%
800.0 MHz 6.49%
400.0 MHz 5.5%
200.0 MHz 9.58%
100.0 MHz 75.13%

[Q] Battery efficient rom+kernel?

hi
sorry for being such a nooby mcnooby-pants
but i just want to know which combination of roms and kernels will give me a great battery life and at the same time i want to be able to overclock to 1.5 GHz
i looked through the forums and i did all the basic stuff like
undervolting
setting profiles in setcpu
and removing all the bloatware from the phone
but everyone has a different combination and im really confused as to which combination to use
right now im using eaglesblood 2.3.7 with the dragon kernel and its really not working very well
so any and all help will be appreciated
thank you

My opinion:
1. Jump on a stock-based ROM with stock kernel and UC (underclock to 900-800 Mhz, you would be surprised you notice very little change in performance). Most stock-based ROM users report back great battery life.
2. Jump on a CM7 Nightly 199 or higher (Reports of great battery life, I can attest to this) with morfic or faux123's kernel (I prefer morfic's) which you can undervolt easily with Pimp My CPU (search XDA). I prefer it to SetCPU because the only profile I use is UC when the screen is off and with Tegra's DVFS CPU governor, it already does a good job of doing this. I also UC with this setup.
Delete Wi-Fi Calling (Kineto.apk) from your phone if you're not using it. I learned this from lotherius, it's always running in the background even when off and not in use. I was shocked to see the improvement.
I know it sounds stupid, but if you're in class or at work and don't need a barrage of updates on your phone, just turn off data. Most ROMs have a quick toggle setting to efficiently turn it on and off quickly and you'll be quite happy with how long it lasts. If you have to have data on or think it's moronic to have an Android phone that's not does not always have a data connection, battery drain is just the price that is payed.

woah.
Awesome answer
so do you think option 1 is better or 2?
does using cm decrease the battery efficiency?
if it does do you think the extra functionality in cm makes up for the batteryloss?
Thanks btw

Try miui 1.11.4 from whitehawkx with faux kernel cm-4.4

Good question, and I think that is totally up to you.
For example, my father and I both own G2x's, he runs a modified stock ROM (xboarder's ROM) and I run CM7. Without a doubt he gets better battery life than me, but at the cost of not having the features I have.
That may be a rough way of putting it but yes, using CM7 with all it's awesome features come with the price of not being as battery efficient.
The real question is if being less "battery efficient" actually means it's a bad thing. In my case it doesn't matter to me at all. Using the quick panel toggles in CM7, I only turn on data when I need it and I easily pull 15+ hours a charge because of it, assuming moderate usage.

Consider lotherius's tsugi rom, currently in version beta 3. It is my daily driver, stable, faster than 2.3.3 based roms, and excellent battery life. He has included a 2G toggle app that can automatically switch to 2g radio when screen is off to save lots of juice.

[Q] Which is the best ICS Rom-kernel combo for Nexus?

Hi guys, in these days I'm trying many different roms to chose the best one. I've tried these: AndroidMe, codename android 1.3.3, CyanogenMod 9 v4.0.3 v2.1 and CyberGR-MOD with the respective stock-kernel but no one did satisfy my desires.
I just want these "mods"
- configurable Toggles in status bar (so that i can switch on and off 3g data just with 2 screen taps)
- Battery icon with % of battery left
- Configurable Lockscreen (I need at maximum 4 targets)
- TouchWake (the screen turns on with just a finger touch on it)
- Maximum frequence of cpu at 1,2 Ghz
Now comes the big problem! With all the roms I've tried some of this was not available. The best one was cyberGr-Mod, but I had a lot of battery drain.
Which combo Rom+ kernel do you suggest me to have the things I wrote before and also a great battery Life?
Thanks a lot

There are quite some points you want in your rom, I'm not sure if there is any that fits you needs.
But let's see:

I know that feature only from CyanogenMod. That latest version (which you also tried) has them build in but not to a 100% complete. Almost every Rom needs some more development to get all the features implemented it should have, so maybe you need to wait a little.
- Battery icon with % of battery left

This option does not need to be implemented in a Rom, you can easily change the batter indicator yourself with just flashing the Icon you want. At least for CM9 there are some links in the Rom-Thread.

Most Roms and custom kernels have more overclocking, but that it no need at all. You could either use SetCPU to limit the cpu or for example a Rom like CM9, this has additional options to limit the cpu.

Why not taking cyberGR when you liked it most and try some other kernels till you find what you want. I would try either the GlaDOS kernel or the matr1x one and then trying different governors in the cpu settings.

aokp + air kernel

All that u want i have in my combo (ROM+Kernel). I use apex (bixie) v.1.0.0 + matr1x kernel v.16.5 (see a review of this combo on nexusshacks - really rocks, i get with normal usage almost 2 days of battery and there are really a lot of tweakable options).
The best combo i've tryied.
cheers.
If i helped u somehow, pls hit thanks button

forgot to mention, whatever rom u're using, try out NStools ans see if the tweakable options there avaliable are enough for u.

Sorry for the strange method to answer you but the multiquote-button didn't work

@ sean1984 : Which rom AOKP do you suggest me? is cyanogen the best AOKP or there is something better?
@ kalitza: I went suddenly to check the rom you suggested me on nexushacks, there are many positive comments but also some users which couldn't install the rom for some problems... above all, I will surely give it a try.
Now I'm testing Codename android 1.3.3 and everything except the statusbar toggles (limited to 4 and not customizable,that means no data toggle) seems to work well, i'll use it again a couple of days to have a better idea and then (after nandroid backup if everything in the rom is ok) I will try the one you suggested me.
About NSTools, where can I find the last release? does every rom have a specific release of NSTools or it is universal for every Rom?

in CNA 1.3.3 go to Settings - Interface and touch Notification widget text, it will open toggle menu where you can choose which ones you prefer

Don't worry, you'll become a regular crackflasher very soon Speaking about ROMs, my favorites are CNA and Nuhetri, pair them with speedy-7 or air kernel and you're good to go, just delete RAMDISK folder in speedy-7 zip if you're flashing it on CNA. It's great to see how ICS mods keep evolving, thanks again to devs and their hard work...

Today I'm trying CNA with kernel Matrix, good battery life but the phone seems a little bit laggy sometimes.. I will surely try the Speedy-7 that you suggested.
Yes It's a great thing that these roms keeps evolving, the only thing that I don't like very much is that there are so many different roms that is so difficult to chose the best one, imagine if there will be only 2-3 roms (for example 1 MIUI, 1 cyanogen, 1 AOSP) and all the developers focused toghether their efforts just in these 3 Roms, I think that now we would already have perfect kernel-roms completely free of problems, full of features, and with 2 days battery life

Yes, I agree with that. We have too many similar ROMs, but I see more and more teams forming, like CNA for example and the result is obvious. I am no dev, but it's kinda hard for a single person to maintain ROM on regular basis, refreshing it with new mods and stuff like that due to lack of time... So, hope to see more teams developing a single ROM

[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.

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!
