[Q] Batery life and where to instal android

Hello.
I've just installed android on my HTC Tytn II (Not so Super Froyo Release).
It is very nice but the battery life is very short. I don't think that i can manage for one day without recharging. I think a couple of hours just. Is there something i can do to improve this? When i entered the #*#*4636*#*# it says that the android system is the one that keeps the processor running when in stand by. what can i do?
And another question. How is it better to install. On nand system and data? For now, i've installed data on external data.img. But there is not much room for aplications. Is it better if i install data on sd partition? And if so....how do i do that?

If the processor is still running while in standby then that means you have a widget or program running that's preventing the phone from going to sleep. When you install an app in Android always look for "Prevents Phone from Sleeping" where the app installer says what the app requires to access.
Also, as I have said in the help thread, there is nothing you can do about the battery life. It's Kernel related and being investigated, so until that time unfortunately battery life is very short because the phone's CPU while not in standby runs at 100% speed, unlike all other android phones which decrease their CPU speed and voltage when they are idle (sitting at the home screen or even checking emails).
Also, if you are installing into a data.img file on your SD Card, you should have about 256MB of usable space in /data, if you are running out of space with just a few applications, then you are still installing on NAND, as it only has about 90-100MB available depending on how you have your NAND partitioned, please verify that you have fstab set correctly in atools and re-flash your firmware so that it reads the /data partition under data.img instead of NAND p3.
BEst thing to do if you are wanting to install /data on SD Card (or data.img), is have /system on your NAND for best performance when Android is loading from boot. For quick performance, you should have /data and /system on NAND. For more space and stability, go with /system on NAND and /data on either SD Card partition or data.img.

Thank you for the answer.
I have another problem...when i'm recharging the phone...it says that it is fully charged at 90%.

That means there is a incorrect battery calibration number in the kernel. Run atools and check under Battery Settings > Advanced Settings. If you have a 1350mAH battery (noted on the battery itself), input 2160 units.
If you have any other type of battery, take that battery's mAH and multiply it by 1.6 to get the battery units. If the battery continues to stop at 90% after making that change, and the battery is old, then the battery may be losing it's charge and can only sustain up to 90% of it's core charge.

Thank you. now i'm trying with 2160 set in atools. i will inform you if something is wrong
Another question. How can i see the battery status in %?

i think now it's ok. but still the battery life is very short. and somethig is keeping the android from sleeping but i don't know what. when i enter in the *#*#4636#*#* it says that the "android system" is the one that prevents from sleeping.
And another question. What is the difference between panels. If i am installing with panel 1 the screen looks very bad. Now i've installed with panel 3 but i don't see any difference from panel 2. It is ok that i've installed with panel 3 or should i use panel 2?

I need to know how you set your phone up, including kernel, system/data partitions, which build you used, what radio you're using, anything that could help me investigate further.
I have 2 AT&T Tilt phones, one for daily use and the other for testing purposes only. (nice to have friends with connections, I got them both for free).
My current "daily use" phone will use about 1/2 battery per day with moderate use (texting/Pandora/phone calls) and will last 3 1/2 days if I just let it sit in standby. 3G is enabled and I use Rogue Tools to O/C to 480. I get almost no FC errors and everything works as it should. (The only FC I get is with ADW, which I press "wait" and it comes right back). I was able to set up my phone on the wireless domain at work and ported my work email to it.
Again, I would need to know what you're running as it sounds like your phone is not actually "sleeping" when it should.

I've the same problem of battery life, can you tell me how to improve the fix for this issue...thanks

Is something wrong with my Xperia Play R800x?

Ok well let me just start off by saying. I LOVE this forum and the helpful and friendly people. Lemme give ya a run down on what I'm rockin' on this marvelous piece of technology.
Bootloader Unlocked - Check
Root - Check
R800x Timescape UK Firmware ROM - Check
V6 Supercharger - Check (Could use help making it start on boot.)
Better Battery Stats - Check (Could also use some more help since I'm a noob XD. More below!)
Battery Life - QUESTIONABLE
And here lies my problem here. Ever since I switched to the UK Firmware from Verizon's I've noticed the phones true potential and love the UK Firmware. However what is up with the terrible battery life? I've tried everything... It seems to DRAIN 1% every 5 minutes when I'm at school!!
BetterBatteryStats talks about wakelocks. I get this one sometimes called UID and have no idea what it is, and have looked for a solution but found never in ACTUAL terms I could understand. Also there's a blue bar and a red bar on the stats for those. Can someone please tell me the difference between them?
I've deleted Juice Defender as some people said it actually DRAINS your battery more. I've also heard this phone lasts sometimes 3-4 days on a FULL CHARGE?! I'd like that please! :O
Well when I'm at school I put my phones Brightness to 30%, Vibrate, and off WiFi.
I listen to Music and that seems to drain the battery ALOT more than I think it should.
Also, when playing Asphalt 6 HD, I was at 57% battery, I played for maybe under 10 minutes and had 44% LEFT!!! That's TERRIBLE!
Can someone please tell me how to make my battery last like others have it?
I also have 2X Battery installed but disabled and only showing my battery % on my taskbar up top.
Thanks again in advance for your answers and I hope I have provided enough info. THANKS!

If u don't use it during school then power it off. Also kill some tasks so your phone won't work hard and kill morw battery life.

I do use it during school. Sometimes as a Calculator, to text my family or if they have to call me in case of emergencies. I also game on it at lunch or listen to music when on a free period so...
And I do kill tasks all the time. It seems to just open themselves back up. Also I played Dead Space last night with 100% charge for maybe about an hour or 2 and the damn battery drained down to 55%!!!
I was on WiFi as well...

You honestly can't expect a game such as that to run on this phone and merely sip at the battery's juice. The percentage remaining when coming out of an intensive task, such as watching video or playing a game, isn't entirely accurate. Check the battery again after a few minutes of idle time, and it should be a little higher than it was before.
I use an app called Battery Defender. It's very easy to set up, and the main option is to kill the 3G data while the screen is off. You're still able to receive calls and texts and such, but the data is off, since you're not using it. That saves a lot of battery for me. You can also set it on a timed profile, where it shuts off all network connectivity during a set time.

Thanks I'll give that app a try.
Also I just feel I'm being mis-leaded by others then. Because I read on the android Forums people play games from 1-2 hours, stop, go to the store or mall for like 5 hours, come home, play again for another hour, and sleep and wake up with it at 7% charge or something.
Are you saying ti's normal for my battery to suck that much juice on Dead Space?

Dead Space is one of the most graphics intensive games you'll get to see in this phone. It's not Cut the Rope...

Well.. despite my other questions is anyone able to answer them..? ABout the battery stats app and such?
Also what would seem to be a normal rate of 1% battery loss? How many mins or hours do you think seems normal?

Did you wipe your battery stats before installing the rom? Let it drain to 0%, charge it without interruption? after that then you must let it drain fully and recharge too 100% without interruption again. This will "train" the battery. I have a battery calibration app if you'd like to use it

I would suggest you to do a fresh install. Wipe everything and start afresh. Don't restore anything and see what happens.

Yes I have done this. But ONCE. I haven't let it die again yet. Using Battery Defender is saving it's battery atm. Should I kill it again and let it do so?
Also for the Battery Calibration don't I have to do some weird thing with getting the phone to power on without the battery?

Make a backup of all your data, then do a fresh install. The battery calibration app is simple, charge your phone to 100% and click calibrate. Then let it die to 0% and fully charge without any disruption..it's pretty simple

Must I make a fresh install or can I do it without a fresh install?

The battery calibration has nothing to do with a full wipe and reinstall. The fresh install is simply to fix problems that you are having, that no one else has, or doesn't have in such great force.
If you're worried about losing your data, get an app called Titanium Backup. It will allow you to backup your apps and app data to your sd card, then restore them at any time you deem necessary. There is a free version, but I would definitely recommend buying the unlock key. It makes your restores faster, and enables some specific functions that are locked out of the free version. This is my third Android phone, and the app has proven its usefulness time and time again, across each of them. It's the best way to port installed apps from phone to phone, as well.

Here's the thing. I have Titanium Backup. XD And also, I have done a Fresh Install before because I had this ROM then I switched to ICS Beta which was terrible so I fresh installed the UK Rom again and it didn't make a difference to when I had it before ICS BETA, so does that count? x.x

[Q] sd card battery drain

SDcard show up under battery, surprising since there is no sd card in a galaxy nexus..
Anybody know what's going wrong or how to stop the battery drain ??

I've had this exact same issue! It happened at the same time as my other issue of app sizes continuing to climb upwards and the phone getting laggier in this thread:
http://forum.xda-developers.com/showthread.php?t=1715363
I just resorted to a factory reset, which resolved the problem. Sorry I can't be of much help, as I still have no idea what the issue is, but it was definitely taking a noticeable toll on my battery life.

I would be concerned of what you have installed on your device, that it is calling itself sdcard.

Nexus internal sdcard is mostly named just sdcard, but this is first time i see it in battery stats. Maybe it's some bad app? Maybe you should uninstall apps one by one and see if it's go away.

Nexus does not have an internal sdcard and symlinks cannot use battery so I would say its an app.

I mean that 16gb internal storage which is called sdcard in most apps. And i know that it can't be in battery stats, that's why i said it's an app.

Same problem, a solution without having to do a factory reset?

Anyone come up with a solution here?

So I'm guessing the lack of responses in this thread (and this one http://forum.xda-developers.com/showthread.php?t=1792361&highlight=sdcard+battery) means no one has any idea why SDcard usage would be so high?

Maybe it is not the amount of power that sd card uses, it is amount of power that the phone uses to read the sd card. If you did lots of things that needs reading from sd card, battery show that kind of information. Some program with wrong commands may couse this

Thats what I figured but there shouldnt be anything thats accessing it, especially overnight in sleep mode, the SDcard has more CPU usage time than any other app, by a landslide.

Have you looked at your running apps? (Settings>Apps>Running)
Maybe you can find out what app may be running called "sdcard".
Sounds a bit fishy. While there is no physically removable SD card, the phones internal memory is partitioned so you have some space which is recognized as the 'sdcard'.
In any case I've never seen anything like that in my battery drain, and even if there was, it definitely shouldn't be draining those amounts while the phone is idle..

I've gone through them but can't seem to figure out whats going on...i've also run logcat but that hasnt turned up any useful info either.

And when you press on sdcard under the battery usage, what screen shows up? Does it say it's an app? Could you provide a screen shot?

Here are screenshots from my battery usage, after clicking on the app, and my build info. I've got the same thing and its completely eating my battery life. This was within 1 hour of use.

This just started happening to my galaxy nexus -- no idea why?
GSAM Battery Monitor shows System (sdcard) running at 17% and its really affecting battery life, I can actually watch the number drain by the minute.
I am not looking to do a factory reset again and I am running Bugless Beast 4.1.1 rom and have been for about 2 months now and never had this problem, anyone have any idea what could cause this?

Just started happening to me today. I just installed lookout so I hope that is the problem. Just uninstalled it to see if that was the culprit.

I'm 100% certain Google Music is causing mine.
Mine always says sdcard and media are the processes running that are eating my battery.
I can reboot and fix the issue, temporarily, but as soon as I play Google Music it starts back. I'm going to clear data and cache (for Google Music only). Now that I think about it this has been happening since Google Music's last update ~1 month ago.
I'm running the latest Trinity kernel and RasBeanJelly, but this happened while on Bugless Beast as well, so it's not a kernel/ROM issue either.

S3 Massive battery and "Android System" usage with and without charging

I'm having a problem with my Samsung Galaxy S3 (rooted, but no custom ROM) through AT&T where it's losing battery power at a much higher rate than normal every once in a while.
Specifically, today, I was using the GPS feature and charging it in my car, and yet, even though it said it was charging, the battery continued to lose charge. Also, in the past, the phone has lost charge very quickly, and when I check the battery usage, "Android System" is very high on the list, up to 60% (with "Screen" being at 11%, which is usually the biggest culprit for me since I leave the screen on a lot). One time, I went to bed at around midnight and had forgotten to plug in my phone. When I woke up it was off. I turned it back on and looked at the battery stats using 3c's Battery Monitor Widget and saw that it lost charge quite slowly until about 5am, when suddenly the usage went up dramatically, and the phone went from about 60% to 0% in the course of an hour and a half of non-use.
Because this is not a problem I can reproduce on command, I'm not sure exactly what application/process is causing it. Does anyone have any suggestions or has anyone else experienced things like this happening before? (Besides me having to pay for the "betterbatterystats" app?)
Edit: Also, "Android System" sometimes is sometimes listed as "gsiff_daemon" in the battery stats, and within 3c's Battery Monitor Widget, Android System is separate from "gsiff_daemon", where gsiff_daemon's usage is almost 15 times the usage of Android System.

Checkout this thread to see if the gsiff_daemon is your problem. tl;dr when the system is hot and tearing through the battery, go to system settings -> Developer options -> and check Show CPU usage. If gsiff_daemon is the top or second highest on the list, then that is your problem. To solve it for the moment, use system tuner, or something else, to kill gsiff_daemon. There is no permanent cure at the moment, other than to delete gsiff_daemon. Both of those fixes require root, the non-root fix is to reboot.
If gsiff_daemon is not on the list, then something else is the problem, but Show CPU Usage should give you an idea of what system process is running hard.

Samsung Push problem
J M L,
Thanks for the information. I'll do that if the problem arises again. However I also did something else that looks like it may have been the solution for my particular problem, which was disabling the "Samsung Push" service in the Application Manager. So far, my battery life has gone back down to very reasonable levels.

Interesting, I installed "micro cpu monitor" shows thin line at top of screen showing both cores.
I haven't had this happen for some time now but after playing with google play and maps downloading offline maps etc I noticed my 2nd core pegged out.
Having seen this in the past & ignoring it I now realize that majorly drains the battery as well as it getting warm.
A simple reboot seems to be the only thing that fixes it. Clearing ram and closing recent screens dies nothing to clear the "cpu jam".
If left alone, it always shows the culprit as "android system"
As to what part of "android system" I don't know.
But until we figure this out for good, that little micro cpu monitor. App is sweet for peace of mind to know all is well or whether a reboot is needed. For what it's worth, I also noticed that after the event, that my auto rotate to landscape was mysteriously unchecked?
If it jams again, I'll have to see if it gets unchecked again, unknown if there is a relation.

do any of you guys have the "increase volume in pocket" setting on in phone-->settings?
also do any of you have motion settings enabled and/or autorotation on?
Seems it has to do with the gyro issue
also are you guys rooted or non-rooted?

Contact sync?
i noticed this today and while troubleshooting, noticed contact sync from google says "sync is currently experiencing problems..." maybe?

I read the thread about gsiff_daemon culprit. I had it listed as a possible battery drain culprit. The thread says the issue may happen after a hot reboot...which I did have. Killing gsiff_daemon was not immediately effective. I renamed the file so it wouldn't get used...like the thread recommended. I had to reboot to get normal battery drain back and have yet to see the issue again. But i wont know for some time...or maybe when/if i get a hot reboot...which is really rare. Do yourself a favor, and buy better battery stats. Its a must have tool...and it's not expensive.

I wonder if this problem has been solved with latest lj7 jellybean from sprint

so with some trial and error i found some resolutions ..
first, i used Watchdog and it told me that the media services is killing battery too.
so doing a full wipe does not always fix this.. but what does, is reboot and wait about 1 hour charging and it will calm down. this was just something i noticed. so what i did is wipe out my SD cards, both of them, cleared them out 100% formatted the External SD, and used recovery to format the internal. From there it seem to work, i put my stuff back, and it seems ok.
problem is, when you install a lot of rom's and have bad reboots some files get messed up and you have to do it all over again..
problem was with AOPK, CM and TW roms.

My experience with froyo/gb/ics is that things have been getting progressively better over the years. But with each so called UPGRADE of an OS or even APPS, we often have to deal with bugs or incompatibilities. I am eager to upgrade to a stock based JB soon, but wisdom says, for 20 things improved, there will be 5 things broken....or hurting in some way. Early adopters suffer the most as usually these issues get ironed out...most of them.
BUT...these stuck drains...wake locks etc., it seems they will happen when they do no matter how many issues get fixed. Over the years, I've had random standby drains caused by Maps/Nav. Maybe it's ok for months, then after a particular update, it's back...and unpredictable. The YES...a reboot, just like with a PC, is a quick short term workaround.
Finally, with the App CURRENT WIDGET, there is a provision to watch for high drain in standby. It watches MilliAmp (ma) readings over time..to determine if you have a rogue drain. That's different than monitoring the CPU. (Some drains do not cause much CPU activity) BUT UNFORTUNATELY, that app won't work with our S3's because of a lack of hardware support. Works great with HTC and many others. It's a bummer because I used to use it and have my HD2 reboot if a 15min consecutive high drain was recorded in standby....thereby saving the battery and usually killing the bug.

Crapppp
Jellybean didn’t solve it. Gsiff_daemon just popped up for me. Just renamed it AGAIN.
Hopefully it won't pop up again

Battery Drain and "Android OS" data hog?

Hello everyone.
Don't know if this is a known problem, but after upgrading to 4.1.2, battery doesn't last nearly as long as in ICS or GB. I need to plug the phone one or two times for a while through the day.
Besides, something is hogging the data in the background. I use Onavo Count to keep an eye on data usage, and recently an app identified as "Android OS + Others" appeared on the top list. It sucks around 5 MB a day, which isn't much, but my monthly data cap is pretty low and this never happened before 4.1.2.
Any ideas? Do you have the same issue? Thanks in advance!

Regarding battery drain I advice you to install Wakelock Detector to see which processes are using most of your CPU and battery overall.
After that, if your phone is rooted, install Greenify and freeze every app that you want to freeze when phone goes in standby.

Greenify works with system apps?

Donation version can greenify system apps.
Alternative, although a bit different, is to freeze apps via Titanium Backup.

Try doing a clean install again(wiping data)
Or disable usage and error reporting services...also disable background data(not sure if it's on jb as am on cm10)
Also if u don't use Picasa delete mediauploader.apk in System/App
Should decrease quite some battery and data use

What most people think android os is on a battery use log is wrong. For instance, write down your android os number, go watch a YouTube video through the app.. android os usage should have risen in the battery usage and data usage number. What android os is, is a catch all for apps who don't store stats for data or battery usage under their own name. YouTube comes up in data and battery usage but in tiny tiny amounts, compare it's number to even the shortest video you've watched and you'll see it doesn't match up but what's added to android os does. I use YouTube as a simple representation of multiple apps that do this. Battery usage in android devices can usually be backtracked to data usage, turn data off battery life doubles even triples sometimes.

Thanks, just did a clean install, rooted, and deleted mediauploader.apk. Will report back in a few days.

Nope. Got rid of MediaUploader.apk and the phone is still consuming a lot of data. No difference with battery life either.

I had the issue of battery drain, and phone heating up, and the phone lagging all time, for my XS. Flashed official JB, problems re-occurred after a few weeks. Now recently I again did a factory reset, and has been selectively installing apps/enabling services to locate the cause. Till now I have seen the google location reporting (not the general location settings) consumes a lot of battery. You can try disabling it (from google settings) and see the battery usage. Let me know if that was the cause for you also
