Hi.
After my upgrade to android 2.1 my battery starts to decrease rapidly...
i had 52 percent in the night around 11 p.m when i woke up in te morning 7 a.m it was 11 percent..
Is ter a way to improve battery power..?
Is it possible to monitor which app drains te battery power?
Pls do help me..
Thanks
I had same problem. Try not to charge ur phone via pc to phone usb cable. Try and get a proper wall socket charger. And if u cant then try replacing ur usb cable.

Stop using autokiller apps. If you want to kill apps, do it manually.
I've never had better battery life since the 2.1 upgrade. Here are some suggestions from my experience.
1. Get Juice Defender free from Market, do setup and change nothing.
2. Get Startup Auditor free. Disable face recognition, download manager, google talk service, mediascape update.
3. Get Advanced Task Killer and exclude ATK, Startup Auditor and Juice Defender. Kill everything else whenever you go to lock your phone after doing something.
4. Only use Wifi when you need to, otherwise turn it off, GPS as well.
5. A 3G toggle wouldn't hurt either.
6. Use a wall charger as indicated otherwise if from PC charge in airplane mode.
7. Put your screen brightness below 50%.
8. Widgets like weather apps on your homescreen suck up batt life.
If I get into the 70% range of battery after a day's use now it's rare.
Good luck!

Try going to SETTINGS, ABOUT PHONE, BATTERY USE.
You will be able to see what the top drains are, I do not use any special apps to limit battery use and get only 4 - 8% drain over night. Leave Bluetooth off and turn off display.
Just for the record, juice defender makes no difference to battery life on either of my x10i's since 2.1.
I just trimmed out junk apps and use a task killer to manually kill a few apps I don't often use.
Finally, make sure twitter, facebook, etc are not set to check automatically unless you wish them too. I only check stuff like that a few times a day, no need for them to check x times an hour.

hi...
@Lord Takyon,Tony_C,Smoked33,pabling19,xateeq, thanks for the reply will try out the steps mentioned..
i at first had poor battery life with the x10 2.1. that was actually when i used task panel x and juice defender on it... after a couple of days, though, i figured screw it and rooted the phone and uninstalled all useless apps on it. then i just went and uninstalled juice defender and task panel x. they actually caused battery drain on my phone lol. now i have no battery saving apps running on my phone and it lasts me at least 18 hours of medium usage.
my advice is let android do the battery saving. don't d/l battery saving apps since they run in the background and cause more battery drain.
Yeah - I've been through the whole juice defender, task killer, start up auditor things..... waste of time.. they do more harm than good..
You need to use something like Task Manager (by Rhythm Software) to see what's running - set any persistent tasks/ apps to ignore, and ONLY use it to kill apps which you think are stopping the phone from sleeping..randomly killing things will at best cause your battery to drain quicker (because the processor then has to restart them).. or at worst cause instability because critical tasks aren't running.
Set auto update frequencies to less frequent.. consider how often you view the app during the day and go along those lines.. don't put too many auto updating widgets on your homescreens..

Guys, don't ask me to search again... i really did... and didn't found any answer....
i am new on android.... and it's regarding the battery's life time...
i hope someone give me an answer here....
there're a lot android user saying about advanced task manager, juicedefender, v6 supercharger, cell standby, phone idle.... anyway... i got no answer at all....
few people using ATaskMan and improve their battery life, but few people said it just drain my battery... anyway...i don't see any improvement using that....
i used juice defender to keep the connectivity.... better than keep it all the time...
didn't see any improvement also....
i used setCpu too... keep it low at night.... i don't really know if it works....
all i want is keeping the data on as long as possible.... even on sleep.... to keep apps like viber, whatsapp, im+ and sometime to sync the apps like weather, facebook, twitter and email...
weather, facebook, twitter and email... these apps were set to manual... not automatic....
i don't call and messaging a lot.... just stay on in internet...
i don't play games a lot... maybe few minutes....
so my questions here...
1. did the apps on background really drain up the battery? because they are, who using v6 supercharger didn't have a problem with battery.... and it's not like ATaskMan... it's didn't kill the apps at all.... just manage the background apps...
2. did the widget also drain the battery? some people said so....
3. keep the data on all the time? i read in this forum... they keep their data on.... but, still having their phone more than a day... moveover... some guys get it over 2 till 4 days...
if it's about ROM, it should be same with other, who uses the same ROM...
and if it's about hardware... it should be from the first time i bought this phone....
i just want keep my phone as long as possible with data on.....
anyway.... i still keep tracking what drain my battery the most....
hope someone come with answer for this....
and sorry for my english.....
1. That depends on which apps are running in the background, but when your device is in standby it should go to "sleep", but if you've set some apps to update every 15 minutes, the phone will wake up (without turning the screen on of course) to update them. This will naturally use some battery. And remember that Android can handle all processes itself. You don't need to kill them yourself. That will actually decrease batterylife since the phone has to start the apps again everytime you kill them. A task manager is nice to have if an app is going rogue.
2. Widgets do use battery, and the widgets who are set to automatically update itself uses more battery (Facebook, Twitter, Weather etc.)
3. "This tip is one that seems counter-intuitive, but you can save a lot of wear and tear on your Android phone's battery if you tell it to keep the Wifi radio turned on and connected while the phone is sleeping. Your phone needs a lot of juice to keep pinging those cell towers, and even more to transmit data to and from them. Wifi radios use much less power because of their design, and they don't have to keep searching for a better access point. It's the way cellular data communication was designed, and it's a necessary evil.
But what if you're spending all day (or all evening) in one place, connected to Wifi? If you tell your phone to shut off Wifi when idle, it bounces back to cellular data (be it 2G, 3G, or 4G) and starts sucking down the electrons again when the screen shuts off. That's no good, and easy to fix:
Open the advanced Wifi settings by pressing the menu button, then Settings, Wireless & networks, Wi-Fi settings, and tapping the menu button again. You'll have a choice to either Scan, or go Advanced -- go Advanced.
Tap the Wi-Fi sleep policy entry, and you'll get a pop up dialog with the choices you see in the picture above. Choose Never.
Now even when your phone goes into standby mode, you'll stay connected to Wifi and be able to get mail and messages without turning the cell radio back on and trouncing your battery life. And for the times when you're not in an area with a Wifi connection, just shut Wifi off, either through the menu or with a handy toggle widget. Your battery will thank you for it."

The android OS has a built in task manger so using ATK or ATM is actually worse than if you don't.
But honestly rooting has made all of the difference. If you have time for it READ about what it means to root and the how-to's, youtube instrutional videos, etc.... just get your feet wet a lil bit. When/if you feel like it is something that you might be interested in, go ahead and do it. You wont regret it and you will diffidently be able to improve battery life with titanium backup which allows you to freeze apps that you dont need running.
Warning 1) you might become addicted to flashing ROMS... and 2) if you screw up your phone you can't blame anyone but yourself.

2. Yes it is....
I need root to back up my phone... and it's already rooted... and there're a lot useless program coming with stock rom... need root to clean it also....

at least for my phone: regarding setcpu, you can raise the minimum frequency, increasing performance while hardly affecting battery life (at stock i had 245/600; now i have 480/600). turns out that if you set the minimum frequency low, it will take some juice to ramp the cpu back up
just a little tip
Just wanted to add: besides titanium backup, I'd also recommend gemini app manager and better battery stats. You can use gemini to edit an app's autorun permissions (ie, automatically starting at boot) for those apps you don't, can't or shouldn't uninstall/freeze. If you're having issues with your phone not sleeping better battery stats will help you identify what's keeping your phone awake.
Lastly, there is only so much you can do to optimize your battery life. In the end you're going to have to sacrifice some functionality for better battery life or vice versa. You just need to find the right balance you can live with.
What is the longest running time did you had on your phone? I reckon batteries are getting thinner and thinner and will not last long.
Apps are there to help you avoid manual work. If you switch of automation on all the apps then you will have to spent time and do it all manually and on the other hand how much life will you save lets say %15. Not worth it!
Best solution is to stick your handset to the charger while you are going to sleep!

i set it 300/300 at night... it's from 00.00 til 06.00 which i don't touch it.... i don't know, if it is a good idea.... i guess, background apps wouldn't using cpu so badly.... would it?

im trying tasker right now... 15% fair enough for me.... without losing data....
i am almost 12 hours out there every day.... i wanna figure out, how to spare the battery life... cause i wanna buy tablet.... which consume more battery than a phone....
I have a Galaxy S2 running 4.0.4 IMM76D.XWLPT, baseband I9100XXLQ6 with Siyah kernel [email protected] SMP PREEMPT.
This phone was originally running with stock kernel, but I was having a lot of Sleeps of Death (SOD) and the only way to avoid those was to let the S2 eat its battery at standard rate, which for me meant I would run out of battery in 10 hours standby or so (with auto-sync turned on). Clearly, that wasn't acceptable, but neither were all the SODs, so I installed Siyah to see if that would help.
I imagined at first SODs were fewer, but I'm not sure. I used it with the Siyah kernel (setup as above) for a couple of months and lately it started to misbehave. Any attempt to use Juice Defender or Green Power would generate SODs so I tried using Tasker instead. More and more applications would freeze -- Onavo Extend, Swype, even the launcher. I lived with it because I knew that putting a new ROM on would involve a bit of time spent on reinstalling everything and re-entering settings etc.
However, as of yesterday, suddenly the phone is unusable. It is OK at startup, but after about three minutes it locks up almost completely. All I can do then is turn it off. Looking at the task monitor, I noticed that the lock-up is because there is 0 RAM free. If I look at the RAM from boot, it starts off OK, then it gradually goes down from ~250MB free to zero. At that point the phone is pretty unresponsive.
I haven't installed any new apps lately. I did receive updates to some the day before yesterday (can't remember which ones).
I am now deciding what to do:
1. Try to identify the offending app and uninstall it (in the short window I have after boot).
2. Do a factory reset.
3. Install a new ROM.
Then, today, I took the SIM out of the S2 and put it in a mobile I had lying around because I needed a working phone. I booted the S2 to check the kernel number etc. and what do you know - the memory problem isn't there! With no SIM in the phone, it free RAM stays at ~250.
Questions:
a) What is the best way to diagnose which is the offending app? Is there a way of seeing used RAM and sort by it (on my "Running" tab, there is no sort option, and on the "All" tab, where you can sort by size, it doesn't seem to be used RAM that you see)?
b) What should I deduce from the fact that the problem only happens with the SIM installed?
c) [million $ question] has anyone found a SOD-proof ROM/kernel combination that gives decent battery life?
Much obliged.

2) dwnld and install 'GSAM Battery monitor' app from stores and see which app is causing the memory issue for u.
3) Remove that rogue app, put back ur Sim and then see

I should have been more clear: In my hunt for good battery life without SODs, I first tried JD, then Green Power, then Tasker. At the moment I have neither JD nor GP installed.

OK, so I installed the free version of GSAM. I can't see an option for tracking RAM though. Am I missing something? I see options to review battery use, CPU minutes, network data, sensor time, awake time, # wakes and GPS time.
Do I need to purchase GSAM Pro to get the RAM monitor ability?
Heisenberg uncertainty principle
OK, I installed System Tuner and used it to look at processes sorted in order of most RAM used. Wouldn't you know it -- now I didn't get the problem with zero RAM, even with the SIM in...
I don't yet know whether this was a fluke, whether somehow I had a problem that went away after taking the SIM out and putting it back in a couple of times, or whether I am subject to Heisenberg's uncertainty prinicple -- I will only get the problem when I am not monitoring it...:laugh:
I'll post back here in a couple of days. I still want to get my battery life sorted so I may try first a reset, wiping cache and dalvik and then possibly a new ROM.
until a few days ago i was getting decent battery life but now battery easily drops around 40 percent overnight without any usage.. when i checked battery usage (I'm on IC) android system and google services had 21% each.. when i try to use amplify/unbounce from xposed, phone lags and random reboots and greenify doesn't help that much either...
is there something i can do?
Maybe you can try disable service and appopsxposed

Try disabling google now, turn off location, wipe cache and dalvik and check if the issue still persists. If yes, try downgrading google play services.
The best way to figure out battery drain is to install either better battery stats or wakelock detector and see which services/apps cause the drainage. I specifically stopped using and uninstalled google now (as much as I like it) and keep location tracking/gps off until I need it because of this very reason. Add in greenify and results are huge improvement in battery. Phones are useless if you don't have battery for its main purpose, phones calls and internet usage.

First of all, turning of location services and Google Now solved the problem for me. From now on I only turn on location services when I really need it (for example Google Maps)
Now another thing you could try is this app: https://play.google.com/store/apps/details?id=com.playfulgeeks.gservicefix
Seems to have fixed the problem for many (check the reviews)
I recently installed LS 4.0 on my Razr Maxx and noticed on my break at work i was at around 35% battery, then 2 hours later when i got off work i was at 3%, in that time i didnt have any apps open so the drain dosent make any sense. I took a screenshot of the battery graph for reference: http://i.imgur.com/MyUDnNT.png
As you can see on the graph it randomly drops off there and then goes down at a pretty brisk pace. I wasent using the phone from 6pm to 8pm, right around the time it dropped all that battery.
Could this be due to my battery just dieing out or is it possibly a issue with the rom?

Please describe more information like:
1. was your network set in 3G? LS battery isn't really good with 3G
2. what number of app you are using? social media apps that always updating their data i.e google+, fb, etc --> would increase data usage when they synchronize.
3. please check whether your razr went to deep sleep.
Solution:
1. Set to 2G always and go to 3G if you want faster speed (download the 2g/3g toggle widget for L)
2. Uninstall those app if you're not using it or limit their synchronize routine by the app itself or using profile in Tasker (advanced method)
3. you should installed wakelock monitor app from Play Store
If battery drain were persist when you have done those troubleshoot and solution, you should try to calibrate your battery (leave it shutdown automatically after reaching low level and then charge it until 100%, go + 1 hour to make sure, go to recovery to check the % and then boot to your system and calibrate using calibration app from the Play Store).
Last one, if calibrate doesnt work, then the battery might be already dropped.
Also do check that location services etc are set to power save mode.
Use an app to check wakelock and disable that annoying app.
or may be you are right... lets hope not for your own wellness!
I also remember having that problem when I was on cm12. After my battery dropping insanely low, it kept long before the little juice left in it run out.
So i thinks its something with the 5.0 ROMs
