I'm just wondering if there's any known methods to increase the battery life without sacrificing performance. I know the basic stuff like turning off Gps, Wifi, Data, etc. when not needed but is there anything else I can do to prolong the battery life? I'm currently running the wanam lite rom with trininty's alpha 7b kernel. A couple of people reported great battery life with this combo but I'm only getting a little bit better than stock battery life.
[T-Mobile, Samsung Galaxy SIII] Exel:
What exactly is a little bit better than stock? How many hours are you getting?
[T-Mobile, Samsung Galaxy SIII] theboss23:
Well with moderate use ( 3-4 hours of web browsing, playing games, etc.) on stock I get about 9 hours and with this rom and kernel I get roughly 9 and half.
[T-Mobile, Samsung Galaxy SIII] jgalan14:
I get the same too, kind of hate it :/ I don't understand what drain so much when the phone is not in use, I always wonder why stand by time is so bad in my phone, I get much better battery life rooted but I'm stock right now, I got tired of flashing roms and I hate to wipe every time I flashed so I prefer stock to stop doing that
[T-Mobile, Samsung Galaxy SIII] theboss23:
Yeah, The rom is based off of stock H2 and is supposed to have some battery tweaks to make it last longer. All of the people said battery was good using this combo and 1 person said it's been 1 day 16 minutes, and they had 26% left but they didn't post the usage.
[T-Mobile, Samsung Galaxy SIII] einrae214:
Ok this is with the stock rom. Heavy usage by my means any way. It was on the charger for a few mins here and there. But really not enough to show real battery increase.
[T-Mobile, Samsung Galaxy SIII] theking_13:
The best way to determine battery life (not I played a game for a little, surfed the web over 4G, called some, texted all day) is to take a screenshot of your Screen On time, and overall time since charging. Otherwise, your statements are pointless.
[T-Mobile, Samsung Galaxy SIII] gonnapushthru06:
If u have a rooted device u should try the highonandriod Rom it dies have better battery life than stock
[T-Mobile, Samsung Galaxy SIII] theboss23:
Well the purpose of this thread wasn't to solve an issue with my battery life or determine my exact amount battery life, but rather to find out if there are any tricks to improve battery life. So there's no reason for me to post any screens of my battery stats because it's irrelevant to the thread, I was just wondering if anyone knew any tricks or tips they use to improve their battery life.
[T-Mobile, Samsung Galaxy SIII] theboss23:
I'm very happy with Wanam Lite for now, it's so far the smoothest stock rom I've flashed and I'm eagerly awaiting the next update, so I don't really plan on flashing anything else for now. Thanks for the suggestion though, I'll definitely give it a shot when I'm looking for another rom to flash.:)
[T-Mobile, Samsung Galaxy SIII] lazarat:
Disable auto synchronize. Thats the key.

[T-Mobile, Samsung Galaxy SIII] joshnichols189:
Don't use the phone. The screen will almost always be your biggest power draw. Screen-on time is relevant because if you have the screen on for three or four hours you aren't going to see battery life that is any better.
[T-Mobile, Samsung Galaxy SIII] theboss23:
Your right, it is relevant when comparing, but I'm not comparing anything here just looking for tips and tricks. I looked at battery stats when I compared the stock battery to the rom battery and recorded both stats on heavy use. If you want statistics, I got 9h 38m of battery use, internet and netflix took up 31% battery consumption, games took up 23%, phone calls and texting took up 12%, and the other 34% is basically screen off time. These were the stats from when I tested it on the Wanam Lite rom. I'm not confused as to why it only lasts about 9 and a half, hours as you can see I was constantly on the phone when I was testing it.
[T-Mobile, Samsung Galaxy SIII] joshnichols189:
Well not only were you watching a video (I assume, instead of just browsing) Netflix, you were streaming. That probably did a number on your battery. I know I cannot stream Netflix for very long if I want my phone to last through the day. Also games, things that will ramp up the processor, etc while using the screen will tax your battery more than usual.
[T-Mobile, Samsung Galaxy SIII] jcbofkc:
Some may not like my answer because it removes some bells and whistles, but I suggest turning off all the motion features. Just my two cents. Battery life was better and I found most of the motion features unnecessary.
[T-Mobile, Samsung Galaxy SIII] lazarat:
"Dont use the phone" ....LMAO!!
[T-Mobile, Samsung Galaxy SIII] theboss23:
Yeah, this isn't my everyday use, nor would I do this if I was trying to maximize my battery life. This was purely for testing the battery life on heavy usage and I found that it was only a little bit better when compared to stock. I'm in no way complaining, I think Wanam has done a amazing job with the rom. The stability is great, speed is comparable to JB roms, and battery is a lot better. Unless used heavily as shown above, then it's only slightly better then stock which is kind of odd but makes sense. I was just wondering what all a person could do to maximize their battery life, that's all.:p

Thanks for the tip! I'll definitely try this since I don't use most of the motion features either.:)
[T-Mobile, Samsung Galaxy SIII] joshnichols189:
Once again, thanks for the useless post. It's called sarcasm. Too bad your skull is too thick to pick up on it.

No worries! If you have trouble with idle battery drain, something like Juice Defender will help a lot if you're going to have the phone idle for extended periods of time. Other than that, all I can think of is underclocking (I run at 1350), and sometimes overclocking your min-CPU speed can help as well. The thought behind this is is that the CPU will be able to finish tasks faster, even if slightly, and then be able to go back into deep sleep. I know a lot of people on the Galaxy Nexus forums run 700min, 1000max because of this.
[T-Mobile, Samsung Galaxy SIII] theboss23:
Thanks,:) I actually didn't know that, I also heard undervolting can increase battery life and reduce the battery/phone heating up but someone said that it can it will have a major effect on the CPU, not sure if it's true or not.

We found the structure of the Samsung Stellar and we now know where the System, recovery, and boot images are!

This here is some of the file structures of the Samsung Stellar:

179 98 750000 mmcblk1p2
179 99 124785 mmcblk1p3

To extract the images in their locations: you'll need to use these commands:

dd if=/dev/block/mmcblk0p18 of=/mnt/extSdCard/Recovery.img

dd if=/dev/block/mmcblk0p7 of=/mnt/extSdCard/boot.img

dd if=/dev/block/mmcblk0p14 of=/mnt/extSdCard/system.img

This assumes that you have an external SD card.

Romdump

I tried romdump myself the other day on this, after rooting the phone, and romdump can't find /proc/mnt - I see that there is a file called /proc/mounts on the Stellar, however. I'm wondering if changing the references to /proc/mnt in the romdump script to /proc/mounts would help, but I'm a regular Linux person and am new to the way Android does things. You think this might work? I tried viewing romdump in a text editor,but it just spit out some gibberish with the word ELF at the top, which leads me to believe it is a Lua script or something. Do you know what language is being used? By the way, I'm also following your thread with moondeath on androidforums - did he ever get his situation sorted out?
[General Questions and Answers] sovereign73811:
Yeah we're still working on it, but so far Moondeath, AGZealot, and frankly even I have been greatly...discouraged. I wish I knew what langauge was being used for Romdump.

Moondeath so far has been unable to get the screen back so I'm wondering if there's something to the bootloader LCD Density changer did? I thought LCD Density changer only changed the OS.

Lastly, I also found something on that same site for Romdump. Take a look at this:

http://android.podtwo.com/recoverymanager/

Be careful. We only want to extract the stock images and the stock recovery mode image. If it wants to put a custom recovery/bootloader in your phone STOP, or you will be like me and have a beautifully bricked phone. Only stock images will help me now.

It's a shame too. I made some kind of backup on my phone and I can't even access it.

By the way, it's good to have another person on board with this...I just wish we can get a REAL developer on this...
[General Questions and Answers] sovereign73811:
OK people: here's a tip I've received from an XDA developer expert (thanks invisiblek):

Quote:

a quick and dirty explanation (need root)

Code:

dd if=/dev/block/mmcblk0p1 of=/sdcard/output.img

this will save the partition mmcblk0p1 to output.img

now, to determine what partitions are

on my device its:

Code:

ls -l /dev/block/platform/msm_sdcc.1/by-name/

but you're scheme and directory structure there might be a little different, so adjust accordingly

[General Questions and Answers] wolverene13:
Ok, I ran the ls -l /dev/block/platform/msm_sdcc.1/by-name/ command and I do see a "backup" directory and a "recovery" directory. I also see "rpm", which leads me to believe that Android runs on Red Hat. Not sure how relevant that is, but at least there's something that directly refers to what we're looking for. I do remember being asked to back up the phone when I first powered it on after I bought it. I wonder if maybe some kind of stock image is stored there?
[General Questions and Answers] sovereign73811:
There is. See if you can extract the system image and the recovery image.
[General Questions and Answers] sovereign73811:
We think we've found the system image in mmcblk0p14.

The SYSTEM may be in

shell@android:/ # dd if=/dev/block/mmcblk0p14 of=/sdcard/system.img bs=4096

307200+0 records in
307200+0 records out

We may also have a bootloader:

shell@android:/ #
dd if=/dev/block/mmcblk0boot1 of=/sdcard/boot1.img bs=4096

dd if=/dev/block/mmcblk0boot1 of=/sdcard/boot1.img bs=4096
shell@android:/ # dd if=/dev/block/mmcblk0boot1 of=/sdcard/boot1.img bs=4096
256+0 records in
256+0 records out

256+0 records in
256+0 records out
1048576 bytes transferred in 0.129 secs (8128496 bytes/sec)
shell@android:/ #

Now all we need is to find the recovery...
[General Questions and Answers] sovereign73811:
I have a theory:

I believe that the recovery partition is in "mmcblk0p20." This partition is about 6MB and I've seen Galaxy S3 recovery partitions size around 6MB.

Let's try adding this:

ls -l /dev/block/platform/msm_sdcc.1/by-name/recovery

or:

ls -l /dev/block/platform/msm_sdcc.1/mmcblk0p20

Can anyone help me confirm the theory? I would if I had a working phone.

boot recovery

Hey you think somehow if i go into boot recovery, and click on the option that says format from sdcard.. is there a way i can transfer my root files into my sd car (8GB) then root it again? So basically do something from my sd card? instead of plugging it into the comp? And the repair option for the upgrade assistant didnt work since my computer couldnt read my device.
[General Questions and Answers] sovereign73811:
I'm sure you've installed the Samsung USB drivers on there.

It takes much more to "transfer" the "root files" to your SD Card. The only thing you can "pull" from the phone in recovery mode is the Recovery image itself.

I can use that actually. Refer to my previous posts here on this very topic and see what you can do.
[General Questions and Answers] remf4i:
Has anyone tried any cwm recoveries yet?
[General Questions and Answers] sovereign73811:
DON'T DO IT! Unless you want to brick your phone. I did something similar and that's how I'm in my predicament.

Before you do anything else PLEASE backup your ROMs. Look at my past posts of this topic; I think we've found some of the ROMs.

[General Questions and Answers] wolverene13:
Sure, I can try to extract something - any tips on how to do that? I can obviously just Google it, but I'm new to the Android environment. If I could get the device to talk to my Linux box, I could probably do a lot more, but it doesn't recognize the device via MTP, which is another battle I'm working on. As a result, I have either use my work laptop, which runs Windows, or I have to do it directly from the phone.
[General Questions and Answers] sovereign73811:
If I know the code enough, I believe that these commands through adb will extract the partitions in an image file. You can look at the very first post of the topic; I've updated it with some compiled information I've gathered.

[Barnes & Noble Nook Tablet] wellersl:
Welcome to the fuzzy, muddy world of Android development. You and I are fellow beta-testers. :eek:

Which ics rom? CM9 = Ice Cream Sandwich. I don't use it, but I'm certain it supports WiFi.

CM7 (Gingerbread) is widely regarded as the most stable custom ROM currently available. Use CWM for flashing CM7 and CM9.

CM10 (Jelly Bean) is very slick, but the developers are still feverishly working out the remaining kinks. Use TWRP for flashing CM10.

I usually have to remove and reinsert the sdcard before TWRP will recognize it.

Always ensure the table is fully charged before you begin, and wipe the cache/Dalvik before rebooting.
