What about miui battery drain??? - Samsung Galaxy SL i9003

IN my miui,
blacklight of it is gone for using the backlight killer
but there is a big problem
about the battery drain!!!
because i charge it 100%
but after 10hrs
is over 5%
OH~~!!!!
anyone have solution???
pls !!!!
(i am not to hate that)

What apps are actually running in background of your phone? I have only a 20~30% drop in battery level in ~9hr without touching my phone(wifi on).

see what the battery life is like if you turn off the killbacklight app for a day

i only open the backlight killer in background
nothings else

There's nothing you can do at the moment, unless someone fix this nasty bug.
You have to know that Android saves battery switching off your CPU while you are not using the phone (=> deep sleep). The app you are using "kills" the backlight every X seconds, that means your CPU is awakened every X seconds to execute something.
Your screen always on uses more battery than your CPU always on, I think, but it always drains the battery.

Use" ddkp3" as the bottom package will be more power, I tried

I'm a truck driver and I'm a heavy user.
I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Also, Turn off GPS and Wifi when you're not using them.
Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.
Thanks for all the advice this has really helped my battery

3. Installed Brightness Widget (allows changing the brightness from the home screen
There was a recent post that showed a shortcut for changing the screen brightness from the homescreen without any additional software. First, turn off auto brightness. Second, tap and hold the menu bar at the top. Third, slide left to reduce the screen brightness and right to increase screen brightness.

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.

[GUIDE] Battery Management for noobs

Hey guys,
So after many months with the XT720 and alot of flashing and trying to get the most out of my battery, i've come up with a few conclusions about battery life in general and how to extend it. I thought I'd share here. This is mostly aimed at people who are new to android and have not experimented like some of the more advanced users we have on this forum. Hope you find this helpful and please feel free to make additions.
General Battery Info
The XT720 was my first android phone, and I came from a long line of typical nokia phones whose batteries would last for ages. I had no idea the kind of power an android device would use. When I started out using it, i was surprised at how quickly the battery would die. You'd think with advancing software we'd have better batteries but sadly batteries are lagging behind in technology. Generally speaking you can expect the following battery life from your XT720.
Heavy use: 10-14 hours
Moderate use: 16-20 hours
Light use: 1 day - 1 day 12 hrs.
Note: New batteries improve with each charge cycle. It is recommended to go through a few complete charge cycles when you buy a new phone. After that, complete discharges are not recommended and its smart to start charging your phone when it hits the 20-25% mark.
How to improve battery life
1: Battery Calibration
If you've ever flashed a new ROM, you must have noticed a sharp decline in battery performance. This is partly due to old battery statistics left behind from your old ROM. Android is a smart OS and collects information over time. The more you use it, the more accurate it gets. In the same way it collects information from your battery usage and reports your battery percentages according to that. When you flash a new ROM, sometimes android thinks that your battery is 100% when its really lower than that and that causes relative reduced battery performance. To deal with that it is recommended that you use a nifty free app called Battery Calibration from the android market. What this does it removes the old battery stats and allows your new ROM to create its own battery stats. Charge your battery to full, use the battery calibration. Drain once till phone turns off by itself and charge to full again. You will notice a sharp increase in battery life.
2. Battery Managment
We all know that android has its own battery management built in but it usually doesnt give complete information about the phone. For that you need to dive deeper into the settings. Usually if you experience battery drain its because of a rogue app and believe it or not some common apps you wont think off drain unnecessary battery. To see your complete Battery Stats input this code into the dialer.
Code:
*#*#4636#*#*
This will take you to a bunch of options. What you're interested in is Battery History. When you tap that it will show you two drop down menu's.
1) Other Usage
2) Since last unplugged
Other usage shows you how long your phone has been running and how long it has been asleep. Also shows you how long your wifi has been on and running and how long your screen has been on. It is important to see how long your phone has been running. For example if your phone has an uptime of 20 hours and its been running 5 hours out of that. Your run time is 25%. Which is very good. Sometimes an app can run even when your phone screen is off. This will represent a longer run time even when you have your phone lying on a desk or something. See this setting and correlate with the amount you have used your phone. Does it seem normal? If no then use the first drop down menu and select
Partial Wake:
Partial wake is basically, any app which takes your phone out of sleep mode to use the CPU even when youre screen is off. These are apps which need to sync or use the phone resources. In this you will see a list of apps and how much they have caused a partial wake lock. See anything unsual? For me one app that caused unsual drainage was latitute. Yes, i had simply signed into it and i didnt know it was updating my location every 5 minutes. Extreme battery drain for me even when my phone was idle. See which app was draining your battery and either tweak the settings or remove altogether.
GPS, Sensors, CPU:
You can also see these in the first drop down menu. Certain apps like screeble use the sensors alot, and hence cause drain. Obviously games, camera, will stress the CPU. See if anything is causing drain in that and adjust accordingly.
Miscellaneous Information
After you have dealt with rogue apps that you don't use that drain youre battery your battery life will depend on how you use your phone. But hopefull these tips will help you with increasing your battery life. I do have some more information on different settings and supposed battery saving applications.
Autosync: When you enable auto sync, you allow google and other accounts to sync on a regular basis. This is important for people who need to use push email etc. It does not drain battery IF you tweak what you need synced. In google for example you can have your contacts, calendar, google+, google reader, gmail all to sync by default. If you just need email, please untick the rest. This will help you save battery life. Increase your update times for facebook and google+ if you dont recieve many updates all the time or turn them off altogether. If you have many services syncing at the same time you will get battery drain.
Wifi Sleep Policy: This is sort of a hidden menu. If you go into wireless & networks >> Wifi settings >> settings key >> advanced >> wifi sleep policy. This has three settings. Never close down wifi, never close when charging, or close with screen off. If you choose never your wifi will always be on, which will in turn crunch the **** out of your battery. If you use it off with screen off, remember it takes about 5 minutes to turn the wifi off. I personally use the never with plugged in. Its an intermediate. So when im plugged in wifi always stays on and when im not it follows the screen off protocol.
Wifi Vs Mobile Data: Having mobile data on all the time, does not drain battery. The only time the battery gets drained is when the data connection is active i.e you have many apps on autosync youll see your battery going down. If you arent doing anything and your phone is connected to Edge or 3G your battery will drain regularly. 2G networks drain less than 3G keep that in mind. If you are actively using your connection, wifi will take less battery because speeds are faster and you will be using it for a little time. Also your signal strength has alot of effect on battery. If you have crappy 3G signals your radio will actively be searching for a connection the same goes for wifi. That is important to keep in mind.
Control Background data: By selecting this option you can allow or disallow apps to connect to data without any permission. Some apps require this like the android market. If you uncheck this apps wont be able to sync automatically in the background.
Milestone Overclocking: This is fairly obvious. The higher you overclock with higher vsel the more battery drain you will have. Some use set cpu with profiles but I found that if i set the setcpu too low while idle It takes time for the cpu to charge up when i recieve a call or turn the screen on. Ringtones lag etc etc. I let android do my CPU management and its fine. and comfortable setting would be 850 MHZ, 56 vsel but you can change according to your phone usage.
Juice Defender/ Screebl / Task killers:
In my personal experience with juice defender ultimate I found that with the above precautions juice defender didnt make much of a difference and actually used more battery. First off theres an extra process going on in the back. Second activating and deactivating the connection everytime the screen goes off uses more juice because your radio has to search for the signal hundreds of times as compared to not having it in the first place. Screebl is good if you dont want your screen to annoyingly turn off while youre doing something but it surely doesnt save battery life. Task killers are a no no for android. They kill tasks which start up anyways, its better to use autokiller memory optimizer which tweaks androids internal memory settings and allows for more free ram without killing processes without reason.
System Apps:
Some system apps run uselessly in the background specially with stock ROM's this is called bloatware. Remove all unused system apps with titanium backup to stop them from running in the background for no reason at all.
A final word
Finally after all this tweaking, just use your phone as normal. Dont worry about the battery all the time checking how much its drained, itll mess your head up and make you enjoy your phone less. Battery temperature also changes battery life. Keep your phone out of the sun or in hot places.
Thanks, good article.

Could you make a list of the bloatware that can be safely removed?
I figured this would just list all the usual stuff I've heard. I'm glad to say I was wrong! A bunch of useful info here I now plan to put to use. Many thanks
Might want to mention the display being the biggest drain of battery on this phone. Setting it to automatic brightness or lower will increase battery life. I love the screen at full brightness so I don't really follow that, but for those looking to squeeze some extra time and don't mind less brightness...
Thanks guys, glad you people found it useful.

Yes! Can't believe I missed that one out. In the start id use the lowest brightness setting, which would be fine indoors. But outside it was impossible to see the phone because of its insanely reflective glass. Since we have an ambient light sensor I use it on automatic and it does a good job. Full bright strains my eyes abit thats why I dont keep it on full bright So for people really wanting to save the juice you can keep your brightness on the lowest level. Also when you take the phone out of your pocket and use it, its better to put the phone to sleep with the power button than let it timeout by itself. Those 10-15 seconds for each time you use phone count towards many minutes of unused display time in the end and does make a difference.
This is a very gd post with lots o useful info!! ok i have a qn, is using the phone a lot while the charging good for the battery? And if u let the battery charge even though its already 100 percent for an hour good? srry if it is noob qn...

1. Using your phone while charging does not affect your battery life, and is neither good nor bad. It is perfectly normal to use your phone while charging and is sometimes recommended while doing battery intensive tasks for example navigating while driving, wifi tethering, playing memory intensive games and finally outputing video through HDMI.
2. Overcharging was a phenomenom is older lithium ion battery. New batteries have bypass circuits. So when your phone reaches complete charge, it does not charge any further. So you should not be worried about overcharging your XT720.
Hope this helps.
Excelent article and good quality info. Thanks and best regards!
awesome article! Great information. Thanks a lot for putting that together. I have already started using a few of the tips mentioned.

[Q] vodafone 858 battery usage screen problem

Hi guys,
I have a vodafone 858 (android 2.2) phone. Its battery usage screen isn't giving proper information of power consumption. It shows only these items all the time, like this >
android system 96%
cell standby 4%
phone idle 2%
It has never shown the power consumption of other things. such as display, camera etc.
How can I solve this ?
its normal.It shows you what has been using the battery more and not what is draining it.If you want rhe camera and other stuff to show up just use them and you gonna see that they will appear
@ [email protected] no dude, Its not showing when I used camera. other thing is the display, that is one of the most battery drain things of a phone, but I have never seen battery usage of the screen in battery usage screen.
Also I'm using twitter, facebook and browser all the time, but the damn battery usage screen has never shown them.
damn it..Maybe the usage indicator is non-functional.Try downloading spare parts or betterbatterystats.If you wanna reduce the screen battery drain turn off animations,the screen sensor,haptic feedback and lower brightness

Suddenly getting crazy battery drain

Anyone else get stupid fast drain while its sleeping? I have wifi sleep policy set to turn off wifi when screen is off, and using the task manager nothing looks to be running that i havent launched myself. But usually i'd have the battery last DAYS and DAYS if i wasn't using it that much, but the last few charge cycles it's been nearly dead at the end of the day. Is there an app I can get to monitor stuff while its sleeping to see if something is keeping it from deep sleep? I can't remember what i've installed recently that could keep it in wake-lock or whatever. Thanks guys.
There's a build in feature in the settings menu to tell you what uses battery
Check that the wifi is actually sleeping when the screen is off. Tap the power button to wake up the tablet then look at the notification bar in the right hand corner to see if the wifi is turning on and connecting. If its not doing that then I dont think the wifi is disconnecting and turning off when the screen is turned off.
For battery issues, two "must have" tools are "better battery stats" and "cpu spy"
gary's right. download better battery stats here:
https://market.android.com/details?id=com.asksven.betterbatterystats
and since the developer of that app loves XDA, there's a free version for us!

Sorry to push the old post up again.
Recently im suffering from the weird battery drain, i didnt play/use my phone much on sunday , the idle battery drain is huge. like 8 hrs from 100%-40%.
I've installed both betterbatterystats and cpu spy already.
From battstats , it shows that kworker/0:1-3 and kworker/u:12-13 etc using up most of the batt , secondly is the doubletwist music player.
From cpu spy, most of the time is with 200mhz even i didnt use the phone at all, rarely goes to deep sleep mode.
for the process kworker it didnt show whats the process/app is about , anyone else know wt to do now ?
Same problem here :-(
Fully loaded at 7 o'clock and now I'm 34% - this really sucks!

All you can do is to check the apps you recently installed or updated. They might lock you from sleep. No easy way to control this
For me it was the "samsung-keyboard" - I froze it and now everything seems normal.

tiwlan_wq usage 48% and draining the battery

After getting tired of ghost call issue, I'm back on froyo but now new problem. The fkng phone dies when left untouched for few hours. I caught the problem to "tiwlan_wq" process taking 48% cpu time after being idle for few hours and then it totally drains the battery in matter of minutes. CPU usage showed tiwlan taking 48% constantly and my battery just drained out. It's got to do with wifi since at that time the wifi stopped working and the button was ghosted and i couldnt' connect or go to its setting page and only reboot was teh only option to bring it back on.
WTF LG can't have GB cuz of ghost call and now this froyo is useless as well. Seriously thinking of selling it but hv to wait for new quad core phones to come.
Do Use 360 Launcher 360 Guard or any power saver it happend to me once. The Power Saving App (360 battery guard) was unable to turn off the wifi module by trying to kill the process which made it hog the cpu. i think it happens when a process cant be killed keeps restarting.

I'm using go launcher. I had wifi protector app, wifi lock app both of which i have also uninstalled. Will charge it full overnight and then in morning see if this helped. BTW i'm using acura's v3 froyo rom. I have some batter saving stuff as well as uptime and cpu usage apps installed. Any software which can show the process down to root level since cpu usage doesn't explain what is causing tiwaln to keep at 48%.
Thanks for the reply btw
