Battery life question and data2ext question

Okay so I hear all this stuff about peoples phones lasting 2-3 days on heavy use and I'm wondering how u do it I'm running mikshift 1.1 and x99 kernel and I underclock it and even turn off data but I'm wondering what your doing to make this happen my phone will last about 5hrs to 6hrs if I go easy on it
Also I have a question about data2ext can ne1 point me in the right direction for this phone so I can set it up on mine. Just as a side note for those who are oblivous to the obvious I'm on evo shift 4g

you either have a rogue app, instant messenger running, or streaming music running constantly to get only 6 hrs of battery life.
What apps do you have installed or do you have running?
Can't speak to the data2ext and not sure why you'd want to do that, are you experiencing lag?

Very little lag and the only things I leave running is advanced task killer and set cpu every so often ill leave ebuddy running but I shut it off for the fact that it sucks battery life lol

before you get flamed for running advanced task killer - that is probably helping to kill your battery. it kills processes that android will constantly try to restart and this could cause your battery dying very quickly.
remove that, android does a good job with task/memory management all by itself.

I have prob ably too many apps all on sd card tho not real sure which app could be rogue though or which apps rather cuz who knows

I don't know about 2-3 days but I can get about 20 hours with heavy usage running CM7 and x99 kernal. I just leave GPS and data on. The longest I've ever went was this weekend I got 1 day and about 12 hours and had 20% battery left.

Yeah, ATK is a real hog. If you want to be able to manage rogue processes and apps, try auto killer. You can adjust the memory settings for more free ram but still let android handle it. Although I leave that alone actually now, and leave it at the stock cm settings, but still use the process manager to kill any stuck apps

Big fat +1 on the AutoKiller..Used it on all my android devices (Moment, Hero, Evo, and now the Shift). Set it and forget it..just like a Ronco

THANK YOU! Well HOLY ISH !!! Got rid of ATK and the phone is way faster . Don't know about battery life yet. Will post up when I know.

Days? I am lucky to get 5 hours of battery on a new phone that barely has anything installed after exchanging it for one that didn't last 2 hours. I have no ATK on it and no widgets because I am scared to kill the battery. I just posted a long post about it on a battery post. Something, I don't know what is keeping my display really high...at 70% consistently but I have my screen to shut off after 30 seconds. I would love to just be able to go somewhere and use my phone without being worried that it is going to die on me!

Make sure you don't have the craigslist app or yahoo mail app installed as that will kill your phone super fast. If you go over to android central I have a write up on how to make your battery last. I got mine up to 48 hours. Look at my battery thread over at AndroidCentralSent From My Speedy Mc Speederson

Will look at that. Don't have either of those running. I have the email to check at very low intervals. Thanks. I am amazed at all these people who get hours from their phone. What would be the item keeping my display up so high? My few programs I use are at 1-3% but that display still remains to suck the battery.

Why the yahoo mail app? I haven't noticed a difference since installing this. I also run it on my epic and don't notice any problems, but maybe I am missing it.

I have been getting really good battery life lately with miui and tiamat kernel. I got 2 days out of it with 20% left. I'm sure could have gotten another 10+ more hours or of it too but I put it back on the charger lol

I'm on aosp rom running shift deck with sparkos kernel. And I get well over a day with this setup. It all just depends on certain phones. Sense roms will usually be running way more battery than an aosp rom will usually do. Just because its the basic form of android. Stripping all that will help.

i FOUND A TERRIFIC WAY TO KEEP great battery. Go into your task manager and kill all level 2 process' then lock your screen. It will not allow your launcher to start back up until you go back into it. I'll post another screen shot when I'm around 10%

Calibrate your battery everytime you flash a new kernel. theres an app in the market. follow the.instructions and wait a day or two.

Has anyone tested both uv and non uv kernels as far as battery consumption is concerned?

Battery life
Hi all,
I'm new to the android market and a lot of the lingo. Can anyone explain and/or walk me through how to get better battery life? I've gotten several apps from the market that seem to work a little, or at least give the illusion of working (i.e. apkik, juice defender, android booster). So far, juice defender seems to be the only one working halfway decently. What exactly does UV kernel and bali kernel refer to?
Thanks.
I have also considered rooting the system to get rid of some of the crap apps that can't be removed from the phone, but am scared that I will ruin it. Any info will be much appreciated.

I assume you are completely stock? Look for the rooting thread first, after you root look into the Bali Kernel in the development section. UV stands for under volting, meaning your device uses less battery to operate. Along with that, the kernel speeds up your phone quite a bit from stock. Better battery life, snappier response times, sound improvement, etc.
hope this helps
btw, im going on 18+hrs @31%

29h 3m 32s @ 25% battery left.
SWEET! Calibrated my battery. keep data and wifi off unless i need it.
10min of NOVA2, x construction, NFS shift.. some words with friends. 20mins of phonecalls. texting. some interwebs, gps. havent listened to music yet though ..
ill consider this moderate.. PLUS my battery is only 1500mah.

If u search within these forums all your questions have probably been answered already. But to start you off I would recommend grabbing cwm3 final in the development section posted by krylon360. Have fun with your phone. Also u need cwm to flash the Bali kernel.

THE GODS ENVY US!!!!!!!!!

Ok I honestly do not understand how do you guys get that good battery life. I tried everything, black backgrounds, juice defender, calibrated battery, minimum brightness, no widgets. And this is almost a week after the flash so the battery should be calibrated properly by now. I barely even used my phone today but for some reason it died at 6pm......I unplugged it at 9am. I think there's something running in the background that's eating my battery. When you guys clear ram and reload the launchers, what is the used ram usually at? Mine stays at 240, and I think it's a LITTLE too much.

Horrible Battery even with Seidio Ext. Battery *ROOTED*

I know this is one of those things that everyone seems to complain about, but there is definitely something going on here. I have Seidios 3200 MAH extended battery for my ROOTED bolt, yet my friend running the same ROM as me is getting almost double the battery life with a stock battery. I know the first thing to check is if any apps are killing my battery, which I have checked through thoroughly with no luck. I have tried uninstalling these apps with no luck on better battery life. If it helps I'll post the apps I have
- Beautiful Widgets
- Brilliant Quotes Free
- Days left widget
- Draw Something Free
- Engadget
- Facebook
- iHeart Radio
- Instagram
- Twitter
- Yahoo Mail
- Ringdroid
- Root Explorer
- WeatherBug
- XDA
- Zedge
This of course doesnt include the stock apps on the ROM.
Currently running the Plan 9 ROM, if anybody has any tips for getting the battery up to par I would be very grateful!
EDIT: Forgot to mention how long my battery is lasting me. I'm getting about 8 hours before she is sucked dry

Actually it's called "Plan .9" Its only been out for a few days and it's a very very minimal sense ROM. It's missing alot of the sense features as to make the battery better, some people are getting up to 3 days while on it. And the developer is very responsive so far with adding sense widgets and squashing bugs. here is the link...

Yea the Chinese are getting into making bogus crap and selling it in bulk to people on eBay and other places. My stepdad bought a bunch of bnib usb flash drives on eBay claiming to be 200gb and none of them worked. They were some of the best fakes I have ever seen. They were in packing identical to the actual product.

I bought my battery directly from Seidio, don't think its a Chinese scam. But Something is definitely eating my battery, although the battery usage is showing my display as the main culprit.

You're showing 5 hours and you are only at 56%. That would mean you have around 5 more hours. It looks like you made some serious phone calls which would eat up a lot of battery too. I don't know if you use auto brightness but it can help if you disable it and set it at the lowest possible setting you can stand. Another thing you might look into is the Facebook app. It was causing a wake lock on my phone so I removed it and that helped me a lot.

If its a sense rom, try imo 5.2 kernel for sense. Use setcpu for a screen off profile of 245/386. If its desensed alot, you can probably get away with underclocking it to 768. Brightness is huge batt hog, set as low as possible. I have as few things syncing as possible also. Interesting looking rom, i will try it out with my stock battery and let you know.

Ok, its loaded. Fastest booting rom ive had. I did try ziggys 11:05 kernel first, did not overclock, but did set screen off profile. This thing flys, and i havent played much with it yet. Ill let u know more tomorrow.

the best battery life ive ever gotten was from the full blown MR4 rom with the stock MR4 kernel and the MR4 radio
people say that the MR4 Kernel slows the bandwidth down somehow and maybe it does but its awesome on battery life

Thats the thing, I only spent about 15 minutes total throughout the day on the phone so it seems like its eating much more battery than usual. Maybe I'll try a new kernel and see how that pans out.

Id guess its your widgets, im completly stock besides ziggys kernel. Tomorrow ill try the imo kernel.

I'd try to turn off widgets, but also turn off all background running apps.
Seal is a good program to keep apps from turning on imo. I use it to limit usage - on most Roms I get almost 30 hrs of battery life. (Extended battery).
Good trick - overnight I use Airplane Mode and my battery drops at most 5% for 10 hrs.

Also, some of the forums suggest you recalibrate your battery when you flash a new rom... It wipes the battery stats and starts from ground zero. The app is in the play store Battery Calibration. Just charge to 100% and run this app it will do the rest. Don't think that is your problem, but it will give you accurate stats about your battery...
Here is the thread for the Instigator Kernel. If you flash you phone on a nightly basis, you will have to reflash this each time you update on a nightly...
http://forum.xda-developers.com/showthread.php?t=1721235
Another good program to run is CPU spy like I said. It will show you what your CPU's are spending all their time on. Once you get the new kernel flashed, just run that program. You should see more time being spent at the 192 Mhz range or the deep sleep when the phone is on stand-by...
Good luck with it!

That is a little fast, but he did say he's using the device non-stop for 3 hrs on 4g. 4g uses a lot of battery, and 3 hrs of "non-stop" 4g usage doesn't seem that unreasonable. The question is, what does "non-stop" mean to him? Screen on with 4g data being transferred for 3+ hrs strait sounds like it would kill a battery to me!

I agree it is fast. I am not sure if he is on LTE or standard 4G... LTE would drain it if he is in a bad location... There are a lot of factors.... I am sure his huge screen being on has a lot to do with it. Brightness level??? Signal Strength??? ETC...
CM9 is known to be a little bit of a battery hog in the wrong situations... That's why I suggest a kernel that is aimed at GOOD battery life...
But do whatcha want...

Where I am I don't get real good service on Cm9 it says 4G and sometimes it's just H with 1 to 2 signal bars also my display brightness is set to automatic
I downloaded and flashed the instigator + badass I will see if that helps also got the battery calibration will charge and reset it

I sincerely recommend you give a try to sky ics either base. If you choose stock get rid of the bloat. Sean's kernel. I am getting 13 hrs to 22hrs which I did not believe was possible now I have three batteries 2 OEM and one extended and I feel I don't need extra batteries anymore

Besides the previous post regarding sky ics for battery life I have something I want to share with the forum is that I use external charger and in my last charge I am not getting any wake locks I may be wrong but look at my latest battery use
