How do u do tht I cnt keep my battery charged I'm running aosp cmod set CPU everything it just takes forever to charge and it drains quick
Sent from my LG-VM670 using xda premium
If it takes forever to charge, that means something is constantly using the cpu power and causing it to discharge while you're charging it. I use an extra battery charger and just swap between the two. Please post your wakelocks from betterbatterystats (available somewhere on the forums for free), your battery graph, installed apps, and current widgets you use.
Mine takes around 5 hours to charge, and that's when the phone is completely off. I'll do another test run today with Bluetooth and Kaiten mail turned off. From looking at the wakelocks in Spare Parts (BetterBatteryStats doesn't work for me with MIUI), those looked like the two main offenders.
Here is a graph showing my charging time:

Somethings holding a wakelock and causing your phoen to be on all the time.
If Android OS is at 70% or above, you've got something waking up your phone.
If you look around, I've got a thread on known battery drainers here in General. I should ask Jivy26 to add it to the FAQ...
Actually, looking at the graph I think MIUI interpolated between the time my phone died and when I turned it on in the morning, so the 5 hour charging time I mentioned is most likely not correct.
Ok, quick update. I uninstalled some stuff that had a lot of activity in my MIUI battery history. I uninstalled Dolphin Browser HD, Amazon app store, Fancy Widgets, Pulse, Mobile Office, Brilliant Quotes. Also removed the IMDB and Flixster widgets from my home screen.
All of these showed activity in the battery history, but didn't show up as holding wakelocks. I guess whoever the culprit was, it just fell under Android OS.
Anyway, I went to bed with 92% battery and woke up 7 hours later with 91% battery left. This is with Bluetooth and wifi on, running GalnetMIUI 1.11.9 ICS with 200 min/1600 max, ondemand/noop. I guess I can't complain now.
I've also noticed that the ui feels a lot more responsive/less laggy, and the battery drops a lot slower when I'm using the phone.

This is common, if you look at my Known Battery Drainers thread you'll see that there are a lot of usage cases where a rogue app can get its usage blamed on Android OS.
Specifically, any app that drives data to your phone will cause the phone to wake every time it receives data. In some cases, this means 800 milliseconds spent resuming/suspending to process 10 bytes of data (which takes the app itself next to no time.)
It sometimes gets worse on wifi because some apps change data usage patterns when on wifi.
A situation like that usually causes a lot of wlan_wake, wlan_rx, or svnet-dormancy wakelocks in /proc/wakelocks (BBS does not show kernel wakelocks properly yet - chamonix added the feature recently but it's not quite working yet.)
My guess is it was fancy widgets/pulse. I use dolphin browser, amazon app store and they do not effect battery life at all.
That is my suspicion as well, and I will try adding apps back one by one to see which one was the culprit.
Right now RILJ Dialer is waking up my phone constantly with hundreds of wakelocks. Many people seem to have this problem, but I haven't seen a solution.
Well, this is looking very good! I never expected this kind of battery life.
Any thoughts on the wakelocks? Not sure if I should worry about them or not.

I know this has probably been asked hundreds of times and I have searched up and down the forums but have found no fix for my battery problem.
I always have my battery at the dimmest level. Mostly only text, the occasional 5 min phone call and web browse here and there. Yet when i look into the battery use the display is always at atleast 96% ive never seen it less than that. But i kno that it has to be something other than just the display though.
I stoped using beautiful widgets, and froze media hub (i read that it eats battery in the bg) recently ive been monotoring my system through system panel.
As of now system panel tells me that System Processes is at 5.7% and system at 2.6% The next highest thing is Swype at 0.4% and android.process.acore at 0.2% the rest of the things are at 0.0%
I was thinking that it might be the battery or just the phone itself...
Edit: im sorry idk why the app didnt post all my post <=(

Having your screen use that much (as a percent) isn't necessarily a bad thing. It means that everything else is using minimal power. You also shouldn't be checking your stats for useful info within moments of turning it on. Give it a whole day of use and check again. Your screen will have used less % after a day but it is totally normal for it to be the largest user of power.
So then what could be causing the battery drain?

How much drain?
You should expect to get 4-5 hours of use from your Vibrant. Total time could range from four hours to several days, which is what you hear people saying in most battery threads. What they often don't state is how much time the phone is actually in use and whether you get 5 hours or 24 hours before you hit 0% battery you probably are using the phone (screen on for anything, or screen off while listening to music or talking.) for 4-5 hours.
So is your phone getting less use then that? If so then you may have some other issue.
http://forum.xda-developers.com/showthread.php?t=848207
The links are very informative
Of actual use, not just standy by I get just about 4 hours. Usually under 4.
And that link looks pretty interesting

Fast Battery Drain
Bad News Everyone!
I have spent the last 3 days searching here and other forums trying to find out why my battery has been horrible. My battery goes to around 30% after only 3 or 4 hours of very slight use (2 or 3 texts and checking email once).
I have done two complete battery drain to full charge with the phone off the past two days to try and get a better reading.
The history of the drain, at the end of November I rooted and installed RyanZA OCLF, rooted, and lag fixed, no issues. Installed the basics of rooted (busybox, superuser) and SetCPU.
SetCPU presented problems with not coming out of sleep and freezing after reboots. The battery would give about 6 hours of moderate use. I played around with settings, but ultimately removed it and when I did my battery was lasting 3 hours longer with moderate use, facebook, twitter, browser, 20-30 mins of gaming. From 12:00 pm (leaving work) to 9:00 at night (leaving school) with 35-40% left before I got home.
About 4 days ago, my battery was draining very quickly. Wake up, unplug phone at fully charged, get ready for work, grab phone to leave for work and I am down to 90% after only 20 minutes of standby. When it use to have it around 96% by the time I got to work, about an hour with light use. Seeing this problem I went back and looked at updates and apps that I had. The only thing I could think was Launcher Pro, but no one else has reported battery drain issues and it wasnt showing in Battery Info.
In my attempts, I have done the following.
Went from 7 to 3 screens (one widget per screen)
Removed apps and bloatware with Titanium Backup
Doubled checked my account syncs, Facebook once a day, no twitter sync,
Screen brightness at ZERO
2 Battery Resets (fully drained to recharge phone off)
Installed Watchdog to find any heavy mem/cpu users, (none found)
And a crap-load of googling, forum searching (here and cyanogen forums), and I am still getting horrible battery life.
Today for example: Phone completey charged 10:30 am with only 3 texts sent and I am currently at 28% at 3:15. 5 hours of stand-by should not have drained that much battery. No GPS on.
If you have any ideas of what it could be, at this point I have alread bought a new battery, I would love to hear back.
edit: I am running stock rom 2.1-update1
I used to have poor battery life as well on stock 2.1 rom until i flashed the leaked jk6 update. Im now averaging about 25 hrs per charge with my phone pretty much always in use whether its calls, texting, music, gaming, web, movies ect...
Not to mention i also get 3g in places i havent before and faster DLs, less lag... This rom is awesome, i suggest giving it a try..
Sent from my SGH-T959 using XDA App
dubbz106, thanks for the advice. I have not had a huge desire to flash a new rom because my phone had performed pretty good. But with my G1 I was keeping it alive through cyanogenmods.
I have been moving closer to flashing and this new battery issue my push me to do it.
Can you link the thread for the rom?
I have tried everything. I tried various ROM's, SpeedMod kernels T27, T29, T32, and T39, and the stock ROM, and NOTHING is working! I cleared out my Dalvik and cache partitions obviously, and I caliberated the battery. Nothing is working!
I used the phone for 8 hours today, and the battery dropped to 50% in those 8 hours. I had the display on for 1 hour and 30 minutes, browsing Tapatalk and the internet. I made no phone calls at all. Besides that I listened to music for 45 minutes, but that's it. The rest of the time it was on standby in my pocket. This is running Lite'ning ROM v6.1 and Speedmod Kernal T39. However, no matter what combination of kernels and roms I try, the drain is pretty similar.
I have the stock android weather and news app set to update every 3 hours, and K9 Mail to fetch new mail every 15 minutes.
This is with Wi-Fi off, GPS off, and bluetooth off.
What could be affecting my battery so much? Is there any information I should post here from my phone so you guys could see what is causing this? I can't even use my phone for one day without the battery completely draining.
Well, you problaby already knew this, but the real life-sucker in the SGS II is definately it's screen. Get the brightness down low and make the screen timeout after 15 seconds so that you don't waste any unecessarily battery.
Can't help to much otherwise, just got my SGS II a week ago, still getting to know it myself. But hope that helps abit anyway.
There may be other apps synching in background. In my case fluent news trend to hang around. Check if every app is doing background work.

I can assure you mine is worse, drops to 50% in 6-7 hours, but as the other person has stated, the screen is the culprit, when I used the phone longer than you, I would expect worse battery life.
Gosh how I wish this phone was equipped with more energy-efficient, less bling bling screen. SAMOLED+ is only good for show-off, which I usually don't do.
Theres an app called betterbatterystats on the xda forum. Use that and see whats draining your battery, especially in the wakeloks department.
Updated Facebook? It's raping batteries so hard it should be on the 6 o'clock news tomorrow night. Or, you know, pretty much anything these guys say here.
Try to use Betterbatterystats and see partial wakelocks and cpu spy to see if you have any problem with deep sleep! Also take a look to battery usage and the percentage of Operating System Android

First of all I think you are wrong when you say OLED uses more power than LCD. Remember how these screens work, LCD lets light go through and is completely back-lit all the time while OLED screens emit light from pixels that are not black.
On the other hand, the real problem with SGS2, in my opinion, is the reason phone never goes to sleep. If you take a look at screenshot I attached you'll see that screen on my phone was not on all the time but battery drain continued. Also, "awake" bar is full meaning phone never got the chance to go to sleep.
I have no clue how to fix this, maybe someone with more experience can help. I use to have HTC Hero on which I could turn off "Always on" in network settings and get phone to sleep often and save battery that way.

Display drain about 1% every 4 minutes of browsing, this is in your case 22,5% .
Every 15 min email checking and the automatic update checking from other apps does the rest. There is nothing suspicious with your battery drain.

Bad apps?
I've had bad battery drain for the last week.
I've rooted, romed, unrooted, changed every setting I could. Nothing has really worked. I'm was losing between 5-10% an hour.
Then I just wiped everything and re-installed the stock 2.3.3 firmware and started re-installing apps an hour at a time.
Battery burn was going good about 1% an hour installing about 5 apps in an hour until I installed TM World Clock.
Within an hour I had a 10% battery decrease and Watchdog saying that Event/0 and Suspend were consuming the 90% of the CPU. I uninstalled...it went back to a 1% and hour battery drain for 3 hours.
Re-installed TW World Clock to see it was a fluke. Within 10 min. the phone dropped 2%. and Watchdog started sending warnings for Event/0 and Suspend again.
There might be certain apps that aren't allowing the Galaxy S2 to go into a deep sleep...explaining why the problem is so random among different owners pending on installed apps.
Hi All, I have been using the Xda for long time and I am a bit greed and I never register, yep that's right, hate plz come.
But anyway, I have used too many phones that I can't even remember.
Last couples of week, I got rid off my Nexus one and got A Razr, but the disparagement start right with the battery life!
First a few days, I was using only wifi, as one of my number does not has Web pack on it, and I notice a horrible battery performance on the device and I am
Later on, I activied my internet on phone and here comes my theory.
I notice the Wifi is always running for some reason on the background even if I set it as turn of when screen off, when I check the battery usage, it shows almost every second that wifi is on. That should not be right, it should turn it self off when screen off, and it is not doing that.
Second of all, later on, I noticed something like *WIFI* shows under battery usage, and I was thinking what the heck is that, cause there is another "WIFI" still showing, and also something called" .com.motorola.contact. something like that is waking the phone and using the wifi as well.
And there also something like"motorola.home" running and using wifi for ages. Very strange.
OK, then I went out today, yes, I most of the time stay @ home, na I am joking..
I am mostly in a place with WIFI, home, work place, and Uni. All wifi here and there. Today, I took train 3 hrs total out and back from Birmingham to London for those who like stories. it was 1:30 afternoon battery @ 80% then I listen to music for 1 hr and use whatsapp quite a bit(battery hunger app even on iOS)
On the way back I played GTA 3 for one good hour. and it is now 9PM, and 15% left, as later on I tweet a bit, web a bit. which is good, also I took underground so signal is not always there.
After all these my question is for those who had the battery drain, are U in a wifi enviornment quite a bit time and use wifi?
If so, set the wifi sleep policy to Never(this actually will help) and while not using wifi to use heavy data stuff, turn it OFF and see what happen.
Also turn off GPS espically if you have facebook on phone and also the using wirelsess connection for location, turn that off as well.
BTW the GPS on Razr is reallllllly fast on location, it took 5 second to find me from cold boot. Awesome.
And I don't use task killer or smart action, I think using sensor and active these sensor to save battery while they are using a lot juice is not so smart.
BTW: due to I am on and off subway, my iPhone4s dropped a good 15% without any use, it just sitting in my pocket. (as for now, Android is the fun bit, iOS is the backup, as it does hold battery better a bit...lol)
I am on 2.3.6 (651.167.19.XT910.retail.en.EU)
I flash the rom couple of times, it all shows me WIFI is doing some strange thing.
Today still draining and I use a data usage checker and find that moto blur is using a hug a mount of data, WTF!?
I find battery performance vastly better on wifi than 3G. Mine has had atrociously bad battery life recently, so I'm backtracking through stock ROMs to see if I can replicate the setup I got 5+ hours of screen-on time with.
Gotta love those updates. The sooner data works properly in custom ICS ROMs for the XT912, the better.

I've been using SetCPU to create profiles on the ondemand governor and extrapolating from my general usage during commute, news/texts/im, fair amount of screen on time, I'm getting around 10% drain per hour which is fairly nice. With screen off and 3g running leaving the phone to idle, it drops to around 3-4% per hour which is significantly better from what I was getting right out of the box.
Battery test for Motorola RAZR XT910
Yesterday I decided to do a simple test with my new smartphone, a Motorola RAZR, I shall not charge until he get just 15% of battery remaining. So here I will put the results and thoughts about it.
8:00 AM: I woke up and took XT910 off the charger. Wi-fi was turned on;
8:00 - 9:00 AM: I passed one hour using Pulse to read some news, once or twice I shared some news in the Twitter and Facebook, with the Wi-fi on, of course. The Battery got 85%;
9:00 - 10:00 AM: I started to use Whatsapp to chat with a buddy, took at least 45 minutes of intensive use, battery got 70%;
10:00 - 11:00 AM: Cellphone in stand-by, BUT with the wi-fi on, waiting for someone, battery got 60% yet!;
11:00 - 12:00 AM: That one appeared, so I used Whatsapp again for 30 minutes, and battery got 50%;
12:00 AM - 2:00 PM: Two hours with the cells blocked, but still with wireless connection, 40%;
2:00 PM – 4:00 PM: Motorola in stand-by, now with the wi-fi turned off, so, in the first hour, he keep 40% and in the second, he got 30%;
4:00 PM – 5:15 PM: The final test, I passed just one hour playing Ceramic Destroyer without stopping, the battery got 15% and then the phone asked for charging!;
Well, the battery last for 8 hours with wi-fi turned on almost all time, so I think it's was fair, BUT, the battery status is a bit fake, I don't think that the information was correct, but, it works when is a simple test, you know, right?
We all know about the 1,2 Ghz processor, this drains a lot of battery, but the real villain is the connection, wi-fi or 3G, they both spend so much energy of the cel.
My last thought is... always charge your phone when it's possible, even if you don't use in an intensive form, I hope that you'll not have problems because a low-batterys cell phone.
One thing I've found is that when my battery is draining like a tub it's has nothing to do with any data connection. In running apps there's a media process that keeps my phone running at full bore. If I just kill that I get dramatically better battery life. Normally when I don't have to deal with that I can last all day with a quick touch up charge during the middle of the day. This on my xt912.

your right, certain apps can affect battery life so it is ok to kill running task. however just want to make sure other users know that using task killer to constantly kill many apps is not a good idea! most of the apps will prob restart and this cycle will only drain your battery more. whatsapp is a good example, even they state on their homepage you should remove from task killing as battery would drain not just from the constant restart of the app but also the fact that it would continue to regain connection to their server whenever it restarts.
try use a dark colour like black as you know white colour drains much more battery. if your a constant user of google (maybe even if its your homepage too) try use the black google version. save some battery.
i think personally for me 3g uses more battery than wifi. another factor is the network bars that drains battery if low as constantly hanging onto that low connection.
you should try flight mode and see how the battery fairs there so you can get a rough idea.
also come across an app called FreshNetwork which is a signal booster & finder. Android Market - 4.7 out of 5 Star overall rating! (9,152) as i speak, and it does work.. theres been times where ive had 1 bar connections but after using it i get like 3/4bars. so it helps ease the battery drain there as connection is much better.
hope its of some help guys!!
I know theres is some apps that drains battery, one tip is just deactive the auto-sync with your accounts, other thing, I want a batterystatus app, to know better that stuff.
And I will try this connection app, thanks

hey first of all nice site secondly your tips are pretty much on the dot.. just thought of these apps people might find useful
autostarts - helps with disabling apps from auto starting when phone boots up (may be slightly speed up boot?) & also prevent certain app event triggers (maybe an app permission u aint happy with?)
FreshNetwork - helps locate better signals in which in return would improve battery life

Hi,
I've had the Galaxy player for a few months now, and I'm generally very happy with it. Although I get pretty decent battery life out of it, I'd say normally about five to ten days of idle time with roughly six hours of screen on time and about as much wi-fi on time, with maybe an additional three hours as a music player, one issue relating to battery drain appears to be constant. I'm currently back on stock, but this also happened on Eryigit -- I get very slow drain from about 100-80%, then it seems like the battery goes into freefall, going down from 80% down to 25% in a matter of an hour to an hour and a half of regular use, then slows down again until the battery dies. I tried calibrating the battery several times with no difference. I'm guessing I'm getting pretty good use of the battery overall, but this erratic drainage pattern makes me feel like I'm too often close to running out as the device spends around half the time I'm using it at 25% or less. I've read somewhere that the battery level measurement on the Galaxy Player 5.0 is highly inaccurate, and in fact is only a guess based on the voltage output of the battery. I still have to wonder though, is this a normal pattern for this device?
Thanks, Nir
Hey. I've noticed a similar pattern via battery monitor widget, tho nowhere even close to ws prononced as yrs. I generally monitor the mA rate and it goes from -2ma steadily until 80%, the rate then speeds up. W moderate usage, i get roughly 2 days out of the sgp before charging, when there's roughly 30% or less left.
I also remembr some folks mentioning that the battery wont report greater than 80%; i imagine that 80% acts a sort of border where he readings r concerned.
Try out that program i mentioned to monitor usage. Personally, im on entropys kernel and chips rom (occasionally switching to paranoid android), have undervolted it slightly, and added a few init.d scriptsl aiming for optimal battry life. Also, try out watdhdog lite to monitor any apps that might be wakelocking improperly and Gemini app manager to disable ann0ying apps from starting on boot.

Bah, I think I might have gotten a bum battery. Any idea how much screen on time/wi-fi on time you're getting with a full charge? I use BetterBatteryStats to measure, which also helped me diagnose GPS-related drainage issues (those kernel wakelocks went away when I stopped turning off the GPS, but I'm pretty sure it's a stock kernel issue). I'll try out battery monitor. Thanks!
Well, given that you can have it on idle for 6 days, it might not be thay persay
Actually, onnsecond thought Powertutor is prolly better suited for your issue. It can monitor power use per application
High display brightness; wifi that doesnt sleep even w screen off (it never sleeps by default); apps that enable things like gps, that makes requests and sends info w.o yr consent thru wifi- these, among 0ther things, drain battry life and are other things to consider

And cant say. I usually do 2-3 days before i recharge; i rarely go under 20% and dont game
Also, just caught this- gps is a huge power suck. Like huge. That may be yr problem.

It was same for me on stock rom and every other rom..70% of time from 100 to 10 it is staying on 75% and 25%..and when its on 25% it can last all day with moderate usage dont moving from 25.Its because device only measure voltage which is innacuare ,voltage dont drop linear like mah.

well i had that prob with my old SGP but since i messed it up andgot it replaced it doesnt stop at 80% for like an hour it just charges straight through tht was before i had enthropys512 kernel flashed....now the battery is faster to charge
Well, I suppose another plug for Battery Monitor Widget-
It provides a handy estimate for discharges/recharges that's proved pretty accurate. After entering the actual battery capacity and a few cycles, the app estimates charge and discharge time based upon that as well as the readings it receives. The discharge estimate isn't as accurate as I'd like, but that's probably due to my sporadic usage. The charge time, however, should be accurate since charge times are charge times are charge times.
Jeez- I should like contact the dev for a commission on the app at my rate.
Re-flashing the kernel might help, if A) killing GPS (except when, obviously, you're actually using it) and B) getting rid of those wakelocks (try Watchdog Lite-free) don't work. Eryigit's ROM, from what I remember, already has the Entropy kernel baked in
If you do some search through the past threads, you will find some discussions on this very topic.
Even though the battery performance of the device seems to be quite on par with other Android devices I have used, the amount of battery charge that is being reported is, a general guess at best. As it is, it only shows the charges and discharges only at 5% increments and on top of that, as OP stated, it seems to jump around a lot.... 100%-80% normal drain... jump down to 30% and hold... etc... heck! My device will show full charge and the moment I take off the charger, it drops to 80%... I have 4 5.0 devices and they all do that... I have stock GB, ICS and Custom GB roms and all are showing the same thing. I believe it has to do with the way the charge state is being reported... It must be a hardware glitch and I guess that is why no matter what rom you are on you will see this erratic battery % report.
I have stopped worrying about it since it does not seem to actually affect how the battery is performing.
Oh yes, I saw that post when I was skimming search results, but got fixated on the not charging above 80% part and didn't realize it was the same issue. I guess this is normal then. Thanks!
Regarding GPS: It actually doesn't seem to affect my battery life unless I'm using Google Maps, in which case the GPS flashes in the status bar and yes, the battery drains much faster. Confirmed regarding Eryigit and its custom kernel not having the same GPS wakelock issues. I went back to stock because I wanted something really light, what I ended up doing is using Titanium Backup to uninstall anything that showed up in the apps drawer or task manager that I didn't need. That made everything really nice and fast. Of course you could do the same thing with Eryigit. That might be my next move. Or maybe just try the custom kernel with the Stock ROM.
80%

Yeah. I'm currently using Paranoid Android and it only charges to 80%. When I unplug and plug in the device it starts charging again.
I love the Galaxy Player 5.0, but it really bugs me the way Samsung so often completely abandons its customers past the point of purchase. Charging problems, bogus battery level readout, GPS off battery drain, screwy unusable GPS compass... and forget about Android updates. The US version never even got 2.3.6. I really wish there was a viable non-Samsung alternative to the 5.0, but there doesn't appear to be anything else out there that's like it.
Ever since switching to CM10 I noticed my battery drains fast and takes a long time to charge back up. This morning around 5:30 i was at 60 ish% used it for 10 minutes and left it alone while i was at the gym. I just listened to music on the way home (20 min walk) and i was at 14%. What could be draining my battery so fast?
Install gsam battery monitor or battery stats and it will show you what apps are causing wakelock
Gsam lists two wake locks. One is called media server and the other power amp full version unlocker
What do i do once i actually find the culprits?
You can uninstall them or freeze them in titanium backup
Don't freeze media server I'm pretty sure that's from you listening to music.

Lol yeah I would have mentioned that but it kind of seemed like common sense to me
I was getting bad battery at first, something that caused my problem was a different kernel, also another problem was the way I managed my battery. When I go to the gym and I know I am going to be away from my phone I put it on airplane mode or I turn of the other things like mobile network. Also if you have your screen timeout above a minute that can effect it. Also you have your screen a bunch that will mess you up to when it comes to battery life. So just think about some things that won't really drain your battery and that should help.
