[Q] Which battery tweak?

What battery tweak do you think is better:
Deca or collin?
Sent from my HERO200 using XDA App

I myself wouldnt use any. It actually done more harm to my phone then anything. they both took my battery down horribly(im one of the rare ones tho).
Either one is a good choice so either way your ok.
DECA is more customized to help with his kernels if you flash those instead of using the stock CM6 kernel.

No problem..have a good night

I thought it was just me who had that problem but every time I used a battery tweak or memory tweak I saw horrible batt life and it slowed my hero way down I don't get it so I don't use any as well and I still get awsome battey life with a few steps I do I get on avg 16 to 18 heavy use and well over 27 hrs with light or moderate use good luck

Killing my battery !!

Rooted and installed assonance 5.2 and put on some other apps now something is draining my battery like a mother!!! I literally watched it go down by 10% in minutes. Anyone else experienced this? How do I find out which app is the cause of this without having to uninstall each app?
Sent from my SAMSUNG-SGH-I897 using XDA App

download OS monitor or system panel and see which apps are consuming or hogging cpu

I did that and nothing looks out of the ordinary. I'm so frustrated!!! Could it be the rom or is it an app?

No help here...........I got tired of the battery drain from all the custom ROM's I tried (just about all of them) and am now back to JH7, getting almost 32 hours before being drained. I have done some tweaking to it, got the GPS working great and everything works whereas with some of the ROM's something had to be sacrificed.
Here are some screenshots:

In the last screenshot it shows 30 seconds to lock, all day today I was around 10 seconds to lock and 10 satellites.

Did you flash with 100% battery and then calibrate your battery afterward?

No it wasn't at 100%... And no I didn't calibrate the battery... Was I supposed to??

It's certainly worth a shot. I had the same thing happen to me once a while ago and it seriously extended my battery. There's some threads here that describe the process which essentially involves discharging and charging your phone off and on and deleting the battery stats through CWM.
I always flash a ROM with a battery showing 100% and I typically net pretty good battery life doing it this way.

Always recommended to do so whenever you flash...........YMMV

Here's a great thread for you to look at.

So can I just calibrate it now or do I have to reflash my phone?

You can calibrate at any time. No need to reflash.

Maybe before you reflash, please wipe of the factory settings and partition and also the Dalvik cache and battery stats in "Advanced" settings using your Clockwork.

Ok I'm trying one of those recalibrating methods. Maybe I really should've read everything before I flashed... but there was sooooooo many stuff to read and watch...
When you say "advanced" in clockwork, thats the rom manager correct? when i look through it it says advanced mode for premium users only... is that the right app?

I'm sorry but now that I search through the forum I see that its a common problem and it's something I missed. I'm totally new to android (smartphones period) phones and flashing and stuff. Thanks for all the helpful tips!

One question though. When you delete the batterystats.bin file, does it get recreated at a later point or never again?

It gets recreated, yes.

Have to remember as well that each user may see different results with the same Rom. Kernels. Modems, Roms perform differently from one device to another based on a multitude of factors. After you have done the basic steps to try to stabilize battery drain, I would then begin by experimenting with different kernels and modems.
Idle drain is the test I normally use after ensuring proper battery readings, sensor usage and app CPU behavior. Many times simply flashing to another kernel shows immediate results.
Sent from my ADR6300 using XDA App

I've yet to learn about flashing kernels. I'm now running perception 10.2
Sent from my SGH-I897 using XDA App

Download the sgs kernel flasher app from market. Go to kernel thread off your choice in captivate development an download kernel, placing the file on your internal sd card. Run the app which is poetry self explanatory.

Definitely try a different kernal or modem. Generally, you can find feedback in the rom thread about what kernal or modem gives the best battery life.
I haven't used Assonance but I had to flash the firebird 2 kernal to get good battery life with Perception 10.2. Keep trying.

Battery Use

I'm running the CM7 7.0.2. stable version and the battery life is just awful. I don't know if it's something I am doing wrong or what, but it drains fast and takes a while to charge. When I look at battery use on there it says that display is the most, followed by cellular standby. If someone can help that would be great. Thanks!

its like that for everyone.. they are curently working on the problem and have found the problem.. it wont be much longer till its fixed.

Ok great news. Thanks for the info!

Your not using set CPU are you that killed me then I researched ( looked at CM7 thread)
Sent from my SCH-I500 using XDA Premium App

No I'm sure not. What settings do I need to keep in Set CPU?

I am not using SetCPU but I am OC in the CM settings menu and also see bad battery life but I expected not so great battery life. I think Set CPU is really bad in a CM7 rom.

agreed that's the only big downside to cm7. I think bat life is half is stock 2.2

Youre not supposed to use setcpu with cm7

it may occur in process downloading data in background (via WIFI) or if apps auto update is being
need to wait or pull out the battery

i think it's a rom problem,i face it when i'm on that build,but now i change to gueste.. and everything works,try to change kernel.. or rom..

I also had this problem on Parandroid CM10, no sign of life from the phone at all.
However, I reflashed the rom and now it works great.

Ok rom issue then. I will reflash it with a different one and kernel. Any kernel recomendations?

Happened to me on gueste2x v3.8 last night while I was USB tethering...and I was just pushing for a record time running made it to 160 hours and had to pull battery out to get it working again. As mentioned already, it's probably something to do about background data/wifi activity.
Nevertheless, I still recommend gueste2x v3.8 :thumbup: Give it a try

wow, i really wonder which settings you use and which usage type you have. hardly get 20 hours of life out of my battery. im using a jb rom which needs more juice, but nevertheless the difference is stunning. maybe i should start thinking about getting a new battery

Happened to me twice in a row even with temasek. And bunch of times before with variety of roms. Its basicly kernel issue, low voltage set on screen off and probably some background data sync.. Well i hope cm10 is gonna fix this issue forever, because this is making me wanna toss my o2x and whole android to the trashbin and buy a Windows Phone rather.. I Just cant keep a phone i cant rely on

Its happened to me on some other roms too.
I had a feelining it might be a low voltage issue, so i have been setting cpu min value higher but havent solved the issue :/

I kept having this issue with stock CM & faux kernel. I resolved it finally by replacing the battery with a new one.

[Q] Kernel for exhibit 4g at 1.8ghz?

hey guys i herd there is a kernel for this phone that makes the phone overlock to 1.8ghz i cant find it can anyone link the thread to me if there even is one thanks!

They were before, but it is unstable and it fried CPU's so the devs dialed them down

Well thank you good sir!

I am pretty sure you can still download some 1.8 clockable kernels, just not for 4.2.2

Why would anyone want that? It'd be better just to go ahead and run over the phone with a bus. There's a reason the OC kernels got dialed back by devs. BTW it doesn't make the phone that much faster either. If you need 1.8 another phone is the way to go.

Hey i definitely agree... my phone would bootloop if i went above 1631 mhz haha. Hey but i see your using nos. Whats your personal opinion on it, especially considering battery life?

It strictly helps with lag IMO. I just like how my apps run smoothly and I can run multiple apps without the phone crashing & rebooting. Far as battery there is no app or tweaks that will help if you use 4.2. In fact I got rid of my battery apps as they all just eat memory and do things any user with common sense can do.
Sent from my SGH-T679 using xda app-developers app

so did you determine that v6 supercharger is not necessary for our phones if using the latest version of NOS? i only ask because in your sig you used to have v6, but now it's just baked bean with nos.

Thanks ill try that. But by battery life, i meant like does nos make it even worse? Or does it not affect battery life at all? And i have found greenify and juice defender to help A LOT for saving battery.

Greenify is OK but your main battery culprit is Gnow/Maps. Technically Greenify is supposed to be able to hibernate Maps but that is useless as Gnow needs it quite a bit so it gets awaken a lot. I love Gnow and choose to live with that as I use mass transit and those features are needed. However if you don't, then disable Maps and that will increase your battery somewhat.
Far as Juice Defender and the like, they are a joke IMHO. I used Juice Defender for over a year (they haven't updated the app on over a year either) and just like a lot of them you only save battery if you let it disable data and Wifi when not in use. I don't really care for that and can turn those on and off at will myself. Trust me you will see these battery apps are all smoke & mirrors.
Far as NOS consumption of battery, seems to have no effect one way or another.
