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

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.

New personal battery whore record

It's well known I like to be a battery whore, my previous record was a little over 48 hours on a full charge with my Infuse. Today I beat my old record by about....20 hrs!
All notifications off except Gmail. 3g data turned off for about 80% of the time. Wifi on but set to turn off when phone sleeps. I did use the phone, text, talk, surf, etc. Probably would be considered light usage though.

I don't use battery calibration personally. I just keep an eye on wakelocks with Better Battery Stats and make sure to kill apps when I'm done using the phone.

Yea no offense when people give battery stats they give them when they've actually used their phone. Of course a battery will last longer if it's not being used or if no notifications are actually being used. Those are what eat the battery

I never use notifications, never will. This is my normal usage pattern. As I said in the OP, I do use the phone.

Get rooted and remove blot wear
Best way in some sense to get great battery life is get rooted, use Excellent Roms that removes all bloatware and find any apps that are continually running in background and remove them. (Tip) Get titanium backup and backup your apps then remove them but if you need later then reinstall them for future use. Just a few things to mention, so much more to add to save battery. I suggest you just use your phone and try and save in other ways that will extend you daily use.

How much screen on time? That's generally the best measure of battery life, because if your screen isn't on, you're not really using your phone. And a percent usage tells nothing.
My infuse is currently going on 12 days, 14 hours, 16 minutes, 7 seconds since last unplugged with 1 hour 28 minutes of screen on time. That being said, it's because I use it purely as a backup alarm clock without a sim card now that I have my Note, haha. And no, I'm not going to go to the hassle of rooting, downloading a screenshot app, then waiting another 12-14 days to prove it. Just goes to show that battery life doesn't mean much without usage.

Was it with a stock battery

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.
Sent from my ADR6400L using XDA

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.
Sent from my ADR6400L using XDA

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.

Im at 40% after 9 hours, 56% display, 17% phone calls, other assorted. Stock battery. All in all, id say not to bad.
Sent from my ADR6400L using XDA

wonder why mine is that much less... who knows anymore haha

Id guess its your widgets, im completly stock besides ziggys kernel. Tomorrow ill try the imo kernel.
Sent from my ADR6400L using XDA

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.

ROM for best battery life

I just got the Samsung Galaxy s3 the other day and I am impressed. I was coming from an iPhone 4. Only thing I don't like is the battery life. So far I've flashed synergy 1.7, beans build 8, and Scotts cleanrom. Synergy seems to be the best on battery life, but I just want to know what others think. Also, I am running IMO lean kernel .01 on all of them at stock speeds. Not over clocked. Just wanting opinions.

Try synergy 1.3, best rom with excellent battery life
Sent from my SCH-I535 using xda premium

There really is no best rom, it's all about user preference and exactly what you do with your phone. Try them each out for a week to weigh the pros/cons (or in your case scope out the battery life), then go with the one that you like best.

Thanks for the info but I've done that. They all seem the same. I think my real concern is the kernel. I like Scotts cleanrom but I wanna know which kernel is recommended for battery and performance
Sent from my SCH-I535 using xda app-developers app

All the ROMs do a pretty good job. If battery life is your #1 concern and nothing else matters:
1. keep screen brightness on minimum. Screen filter can reduce brightness even more.
2. If you use wifi, set it to sleep unless charging.
3. Don't use 4g. Use 3g only.
4. Disable syncing or data entirely and only manually sync when you need to. (Something like JuiceDefender can automate this)
5. Disable google backup.
6. Disable GPS and verizon/google location services.
7. Disable bluetooth.
8. Check and eliminate all wakelocks using betterbattery stats.
9. Turn off all haptic feedback.
10. Freeze all Samsung and Verizon related services using titanium Backup.
11. Maybe a mild underclock on your kernel.
At this point, you will get great battery on your dumbphone with a giant screen

Haha thanks man. Yeah I'm just stupud about battery. I pay attention to it too much. I'll do all that. Stupid giant screen indeed

I was having horrific battery on 1.7 with IMO's 0.1 beta. I completely wiped and reinstalled 1.7 on stock kernel, let my battery completely die and charged it up last night. Today I am at 90% after 3.5 hours unplugged listening to pod casts the whole time and texting and reddit app. Yesterday I was at 78% doing much less and unplugged for less time. I think when updating to new ROMs its important to do a full wipe and make sure if you use TiBu don't restore any system data. I don't have anything frozen as well

I'm getting almost 24 hours with about 2 hours of screen time, so much better coming from a Galaxy Nexus

hey guys i just got an s3 and im new to this ad understand there more roms. what is currently the rom with the best battery life? I use my phone quite heavily with power saver mode on and it still doesn't last me a whole day. im on stock and still have to root. cheers

most roms are same across the board.. I would recc. synergy as is w/ziggy kernel. turn off 4g/sync/gps when not using it. :good:

[Q] Screen absolutely killing battery

Hi, so ever since ICS, or at least SCv7 (not sure if it did it stock, I switched right away), my screen has bee completely killing my battery
I still get perfectly fine life with the screen off, but it just drops right down with it on even not doing anything to heavy. Definitely a problem not normal.
Anyone have any ideas? Is this happening to anyone else?
P.S. Thanks for the new Q and A section by the way.

What are your screen settings at (levels, auto on/off, etc)? Screen is by far the biggest drain on battery. Check my Battery Guide, last Page for an app mentioned to lower brightness more than the stock settings will allow for- maybe that would help in certain instances. I haven't tried it myself, but will be doing so over the weekend, and if beneficial I will update the OP with it.
My SGS3 is the same as my A2 being that the screen gobbled up battery like crazy. So, I suppose you're not alone, at least with what I've experienced.
Not sure if any of this is helpful, but thought I'd share my thoughts...

I keep it on auto or low all the time. this is definitely a real problem, because it was nowhere near as bad on GB. now I know they fixed the cell standby issue, but I can literally see the battery go right on down when I turn it on. 3-4 hours on would kill it.

Maybe try with auto off for a while, see if you notice any difference.

Turn auto off and get a widget to adjust yourself. Read an article one time how on Android system auto brightness is more harm than good.

Looking at your battery's discharge rate graph, looks pretty normal. There's no drastic drops in battery, it's fairly linear in discharge, and even if the screen is using most of that. However, there could be other culprits. What about sync, or haptic, or any of the other things I outlined in my guide? WiFi is off, from what I saw, but might not just be the screen. Have you tried editing build prop for "deeper" deep sleep or edits to other things? I'm going to update my OP with a few more things I thought of for improving overall battery life this weekend. Maybe some of the new ones will help...

then my battery calibration scrambles ... i did switchin yesterday & it showed me

Same problem here..my screen draining 57%

Why don't you try the app betterbatterystats it's here in xda:
