[Galaxy S I9000 General] haloimplant:
I wouldn't be surprised if your '3000 mah' has minimally more capacity than the stock 1500 mah.

Given that many people post good battery with a wide variety of ROMs/kernels, unless your specific ROM/kernel has a problem I think many of these cases come down to one of two things:

1) usage, the phone will only get 5-7 hours of 'screen-on' usage, period. I was burning through this every day when I first got my shiny new toy, now I use it for about 1-2 hours a day and the battery lasts for 2 days on average. Some 'background' apps can be killer too, for example streaming apps that hit the data and hogs like Tunein radio (which is awesome but actually heats the phone up). In these cases you need to look at your specific usage and adjust usage or expectations.

2) Background crap. Who knows what it is, Facebook, Tango, etc. Last resort is factory reset to get rid of it (although many probably just install the same stuff they had sucking juice before...).

A third reason could be bad reception, especially with always-on data. My phone can idle for many days at my apartment where cell signal is strong and wifi is on. In an area with weak reception and the phone is trying to maintain data connection as well the radio will be sucking up tons of juice. There is no easy solution for this, I don't have much experience with it, perhaps mucking around with modems will help. Juice Defender (data connection manager) may also help it helped my battery life even with good reception but ultimately I don't even need it to go 2 days so I stopped fiddling with it (it has downsides like things are delayed up to 15 min between data connections and also a pause when you unlock phone for data to establish).
[G Tablet General] akaspidif:
Hey everyone,

So I got my tablet today and have been working on it for the past 8 hours!! I finally got CWmod on it and running. Had a nightmare of a time getting it to work correctly and after using NVFLASH to nuke the whole tablet and install the stock ROM, then updating i was able to get CWmod to run. Now I'm having a really odd issue.

I can boot into CWmod. I repartitioned the SD card, mounted it. I can see the device in windows but when I add ANYTHING to the internal SD card it is completely gone once I reboot the device. I'm trying to get a ROM on it but it's like the drive is locked or something really weird. It copys onto the tablet just fine. the second I reboot everything is deleted.

I feel like I'm missing something here. I had that issue with it when I ran the stock ROM. I could change something and it would not stick after a reboot. For example registering my device on kindle and then downloading books. as soon as I reboot the machine it's as if i never registered it. I'm really at a loss as to what to do with this. I can't seem to get it to save anything on the internal storage.
[G Tablet General] akaspidif:
Well after fiddling with it for a while longer I'm about to give up. I used NVFLASH to get it to the stock ROM again. updated to 3588 and yet again, I can't get any changes to stick. I can change anything and everything on it while it's powered on. The second I power it off and reboot it nukes everything I did (and takes close to 5-6 minutes to boot). I even mounted it and deleted every single file on the internal storage. They all came back upon reboot. I reformatted the entire SDCARD, I reformatted all the user data, did a cache wipe.. nothing works. I'm wondering if my unit is defective? at this point I would love to just have a tablet that I can actually use. I can't understand how it's even possible to not be able to make any changes on the device unless it's reinstalling the ROM everytime I reboot?
[G Tablet General] K J Rad:
What version of CWM are you using and how did you install it?
[G Tablet General] akaspidif:
I was running CWM 8. I couldn't install it via the internal storage. It would boot into recovery mode and "install" but once the machine rebooted it would not boot into CWM. I tried it several times same deal. I could install it but once it rebooted, nothing :/..

So I had to use the micro SD card to install it. I edited the recovery command file and pointed it to the SDCARD2. It installed finally, and stuck!

I tried using the microSD card to install the other ROMs. But unfortunately it will not mount in CWM.

I'm trying to get CWM back on it after doing yet another wipe with NVFLASH. We'll see if I can get it to work..

So i'm basically sitting here with a brick.. unless I never power it off lol!
[G Tablet General] akaspidif:
Ok well another odd thing is going on with this. I'm up and running with CWM 08 again. I can turn on USB mass storage mount. The tablet shows up in windows and on my linux box. I can make whatever changes I want, adding files, deleting everything on it. Nothing matters cause once I unmount and remount the device it's all back to normal. It seems like nothing is allowed to write to the internal storage even though it thinks it does write to it??
[Vibrant Q&A, Help & Troubleshooting] Alperon:
I've got my unlocked Vibrant running on AT&T, but I can't seem to get it to switch between Edge and 3G. I can go into the settings and set it to stay in WCDMA mode, but then when I'm in an area of bad reception I end up missing calls (All through VOIP).

When its setup for Edge/WCDMA it will stay in 3G at first, but when 3G gets too low and it goes to Edge it won't go back to 3G at all.

I've tried switching modem versions but I'm guessing its unrelated to that.. well, actually all Vibrant modems are going to be setup for Tmobile anyway, maybe a Captivate modem is the solution, I'll try that and get back.

Does anyone have any ideas of how I can get it to switch properly?

If this modem install doesn't work I'm all out of things to try.

Thanks.
[Vibrant Q&A, Help & Troubleshooting] Longcat14:
As far as I know (and I could be wrong), you can't flash a Captivate modem to the Vibrant, it just makes the radio useless.

You will have to use Vibrant modems, since they are designed for the hardware IN the Vibrant.
[EVO 4G Q&A, Help & Troubleshooting] jdelforge5684:
Hey folks. My Evo got stolen today, and I have a question. I've already reported it stolen to Sprint, started the Asurion claim, and changed the passwords to all the services my phone had stored passwords for. Unfortunately, there's a fair bit of info on that phone that it would do best not to spread. I have phone numbers for the vast majority of my squadron, along with some passwords for a few secure government systems. Granted, the passwords are in one of the password vault apps behind a different master password and I'll be changing them tomorrow morning anyways, but is there a way I can have google remotely delete that app and de-sync my contacts if my phone ever connects to a wifi network (or gets used on MetroPOS)? Sprint says all they can really do is blacklist the ESN, which they've done.
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
I don't believe so, unless you had like lookout mobile, where you pay for the premium service that allows it to do that.
[EVO 4G Q&A, Help & Troubleshooting] dirkyd3rk:
There's a sprint app in the market just for future reference its called sprint total protection app(free). It saves your numbers and allows you to remotely lock your phone. It also sends gps coordinates every 2 hours of your phones location so you can find those pesky thieves and give them a piece of your mind. You get a pin code to login the website to view the gps locations and it works like a charm.
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
That actually works? I have it, but never set it up. May look into it now. :p

but OP, go for that -pushes you to it-
[EVO 4G Q&A, Help & Troubleshooting] jdelforge5684:
Thanks for the snappy replies, I'll definitely be using one of those security apps next time. Oh well. At least now the thieving bastard can never use the phone to its full potential. At this point aren't the second rate providers like Metro and cricket the only ones that will activate a phone with a dirty ESN?
[EVO 4G Q&A, Help & Troubleshooting] dirkyd3rk:
Yes it actually works, oddly enough it doesn't drain battery since it only uses gps to send location then turns back off. I've been using it. Theres a weird issue with cm7 to where the app ask you to turn on gps even though it's on but it works!
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
I believe so, but they'd be risky for flashing it. Unless they tried to clone a good esn...but most people aren't skilled enough or would think of it.
[EVO 4G Q&A, Help & Troubleshooting] jeeplj8:

[General Questions and Answers] dcaples002:
I've been a member of XDA Forums since about October (when I got my vibrant). And I wad wondering how to become a developer. I feel like I should help contribute to this community instead of just being someone downloading and flashing. Im planning on majoring in computer science in college and I know it will help me with this type of stuff but I cant wait another year (Junior in high school)... I would really appreciate it if you guys would point me in the right direction or take me under your wing so I could pursue this interest.
[General Questions and Answers] cashyftw:
I'm doing computer science also to become a dev, I'm a senior! I have no idea, but I would love to dev also, I know it takes a lot of work though.
[General Questions and Answers] javolin13:
Step 1 - cut a hole in the box

step 2 - put your junk in the box

step 3 - make her open the box

step 4 - and that's how you do it (its my d$#* in a box)

haha naw i'm jk, I would like a clear way on how to dev specifically for the vibrant, I've seen a bunch of different ideas and tutorials on how to do it, but their specific for that phone, and its hard to comprehend on how to put the knowledge to the vibrant
[General Questions and Answers] dcaples002:
Yea I know its alot of hard work but it will all pay off in the end.

I think it would be nice if one of the vibrant developers put up a video of how to become a developer and a video of him/her cooking up a rom. Im sure alot of people would take intrest to that. It would also give us enough knowledge to maybe be able to develop other phones or programs.
[General Questions and Answers] jamesd86:
Learn your way around a linux box as it's pretty much necessary to compile source and what not. If you're wanting to develop programs for Android, learn some Java...

there's a few good e-books on amazon for android developing if you can learn from books.
[General Questions and Answers] Mr. Apocalypse:
I think you should start out with themes....so you know exactly which apks control what...which XMLs control what...then get some Linux knowledge so you can know how to tweak for speed....then start to learn some Java and Smali code....and do a sh*t load of research....i tried to create my own ROM based from official Vibrant source....MAJOR FAIL :(...i think my phone went into shock ....but find someone who is willing to teach you...but make sure you're patient enough to learn.
[General Questions and Answers] Romanbb:
Due to the nature of vibrant roms anyone can be a developer! That's a good and bad thing. Anyways... best way to learn is to learn Java. Android is built on it. It may not loom like it on the surface but it helps (ask whitehawk). Mr apocalypse's advice is probably the best.

Also a video is a horrible idea(no offense). It will empower people who have no business making roms to make them. Do you want people who don't know how to make a flashable zip making roms for your phone? It could potentially lead to bad things...

I was where you were a couple years ago (not that I'm much further ahead). Learn you some Linux. Learn you some theming and try and make a simple app for android.
[Touch Pro2, Tilt 2 Android General] sharkman18:
Well I've been running android for a while now and I have tried a lot of things to try to extend the battery life. From the advance task killer to changing settings with the screen. So far the battery only lasts about 4 or 5 hours on stand by. Anyone has any tis to help me optimize the battery?
[Touch Pro2, Tilt 2 Android General] z06mike:
Get rid of the task killer for starters!
[Touch Pro2, Tilt 2 Android General] JAKISTER:
Get a 3500mah backup battery :)
[Touch Pro2, Tilt 2 Android General] sjabbie88:
4 to 5 hours?

Does Your mobile go into sleep mode? (constant green light) or does it keep blinking green or is it constant orange?

Turn GPS and Wifi off..?

I have a Rhod100 and nowadays my battery lasts almost 2 days with synchronising and 3g on. GPS and Wifi are off, unless I need them.

Perhaps the battery isn`t that good anymore like said before, or try to get the phone in proper sleep mode with constant green light.
[Touch Pro2, Tilt 2 Android General] Entropy512:
FYI blinkengreen is only available in the WisTilt2 test kernels.

However - with those kernels and taking measures to avoid wakelocks, you should be able to get MUCH better battery life.

As to task killers - I disagree on getting rid of these. They are necessary if you have any "must-have" apps that like to wakelock our phones. (Like Facebook) - you have to be careful about what you kill though.

Also, you need to disable GPS if you want the phone to enter deep sleep. Something deep in the kernel RPC code wakelocks permanently when the GPS is enabled, even when not actually doing anything.
[Touch Pro2, Tilt 2 Android General] manekineko:
FYI, last time I checked Wifi power down wasn't actually implemented yet, which means that once you power on Wifi, it actually stays on forever, and when you shut it off in Android, it just disables it in Android, not powering down the hardware.
[Touch Pro2, Tilt 2 Android General] arrrghhh:
What? I've never heard of this.
[Touch Pro2, Tilt 2 Android General] manekineko:
It's a bit old, but here are bzo and WisTilt2 discussing the issue on IRC:

07:07	bzo	once you turn off, you can't turn off, lol

07:07	bzo	err I mean once you turn on, you can't turn off

07:08	WisTilt2	huh? you mean when you power wifi on then off the power is still really on?

07:08	bzo	yeah, I guess the original author ran into problem turning it off, so it is commented out
[Touch Pro2, Tilt 2 Android General] arrrghhh:
Hrm, that's not too old. I didn't realize that, learn something new every day :p.
[Touch Pro2, Tilt 2 Android General] pdawg17:
Ahhhhhh...that explains why I don't get fantastic battery life like some of you...I use wifi quite a bit at home as my 3G signal is not great...I make sure and turn it off as soon as I am done with it but I've always felt like my battery drain is greater than it should be...there's the answer as to why...
[Touch Pro2, Tilt 2 Android General] xi.lin:
I don't think so..

I have my wifi work many times and i can have at least one day long using on my rhod 100
[Touch Pro2, Tilt 2 Android General] arrrghhh:
Well if you guys read the log, the wlan only pulls like 3ma idle. So even tho it does stay on, it doesn't drain that much in reality - the fact is it does drain more, but it's relatively insignificant.

Not that the bug shouldn't be fixed, just that the bug won't cause the battery to drain that much faster.
[Touch Pro2, Tilt 2 Android General] slapshot30:
The thing that greatest increased my battery life was getting a simple free data toggle widget. If you really aren't using it all the time you might as well turn it off. You can still text and call with data off. You'd be surprised at how much android wants to use data with things you don't know about. I always check my data by calling *DATA# on AT&T and for some reason it uses way more data than winmo does on a daily basis. (Some of you guys probably know why and have a simple explanation for this, but I don't :p)
[Touch Pro2, Tilt 2 Android General] arrrghhh:
Yea, Android is chatty. Lots of things sync in the background, and depending on the apps you use... Typically an Android device is going to use significantly more data than WinMo.
[Touch Pro2, Tilt 2 Android General] slapshot30:
Interesting... I have a 200 mb limit on my data so I really have to watch that, I knock out two birds with one stone with the data toggle widget i guess. Increased battery life and not going over my data limit. I believe even native android devices have trouble with battery life. Some of my friends with the evo's and epic 4G's almost run out by the end of the day.
[Touch Pro2, Tilt 2 Android General] highlandsun:
A lot of that chattiness is BS that you can't even disable when you turn off all auto-sync options in every app. That's why I use Droidwall, to control exactly which apps get to use the network.

I also use an autostart manager to try to eliminate unnecessary apps at boot time, but I haven't found a good one yet. This oughta be builtin to Android, not a 3rd party app. Annoying as all hell that there's no direct control of background startups.

The other app that usually keeps my phone awake is geniewidget. I should just uninstall it or something, it's way too poorly behaved.
[Touch Pro2, Tilt 2 Android General] arrrghhh:
Heh, I was going to suggest DroidWall when I saw slapshot30's post.

huzzah hyc ;).
[Touch Pro2, Tilt 2 Android General] kuyaChristian:
What's the other autostart manager called, highlandsun?

Droidwall, gotta check that.

All this talk of Android being "chatty" reminds me...

[Touch Pro2, Tilt 2 Android General] highlandsun:
This is the one I have currently https://market.android.com/details?id=com.rs.autorun&feature=search_result

I don't trust it though; I had an earlier version of it and it seems the developer made it self-destruct, then released a newer version with ads and other crap. (Fortunately with Droidwall I don't have to see this thing's ads.) Most likely in the future I'll just write a shell script that issues the pm commands that these things are just a GUI wrapper for. I really detest developers who try to make money off of trivial code.

DroidWall is on the Market, but here is its original thread
[Touch Pro2, Tilt 2 Android General] highlandsun:
I LOL'd. But it'll probably be true in a couple years...
[Touch Pro2, Tilt 2 Android General] highlandsun:
Here's the brute force way to take care of things...

Capture a logcat from the start of boot until a couple minutes after the boot completes. Search through the log for "for broadcast" - this is every instance of an app being started due to some startup event. Go through the list of them and see which apps you don't want, and disable them. E.g., on a recent boot I got

04-23 23:17:17.180 I/ActivityManager( 1289): Start proc org.sipdroid.sipua for broadcast org.sipdroid.sipua/.ui.Receiver: pid=1745 uid=10059 gids={3003, 1006, 1015, 3002}

which was starting SipDroid on every boot. I don't need SipDroid all the time, so I wanted to stop this. So:

pm disable org.sipdroid.sipua/.ui.Receiver

Done, next reboot SipDroid will stay off.

Just be careful and make sure you only disable things that are optional apps, not core Android services. I disabled sipdroid, titanium backup, geniewidget, gmail, and several others that I know are just fluff. Plus a few that may be legitimate, but I personally never use them (like email). Some other things I left alone because they have a legitimate reason to run at boot (like phone, calendar, mms...).
[Touch Pro2, Tilt 2 Android General] kuyaChristian:
I need to learn how to capture a log, and a few terminal commands in order to do that, huh? I don't have much time to search for those... Is it okay to provide links for me? At least I'm not bugging on stuff like 'how do u do this stuff?' I may be a noob, but I'm willing to learn. :]

But that sounds nice to me. Thanks for the tip!
[Touch Pro2, Tilt 2 Android General] Christiaan91:
I'm trying this, but i can't get logcat to work on the boot.

I tried different commands in the config file

- the normal logcat command (but didn't find that)

- cd /system/bin and then the sh logcat command (did find it but can't exec)

nvm solved

Hello friends ..

Im using the version FX06, thas very good ..... But battery is the problem ... Time of version FX04 to FX06 its betther, but dont same with WinMo -..

So. dont thing that led orange or green all time ON , could be to use more battery that just ON with charging ?
[Touch Pro2, Tilt 2 Android General] arrrghhh:
I'm confused by your statement.

If you're suggesting we only turn the LED on when charging, that's not going to happen. It indicates sleep state, so be sure it goes solid green. This means it's in full sleep.
