I have been looking through forum after forum about the battery life on this rom, it has been dropping 1 percent every 2 minutes or so and is about to be dead. Does this sound like a battery problem or should i just recondition it. I just wanna know whether to buy a new battery, get a new rom or what?
Ive been having the same problem, ive already tryed the reconditioning process but i still lose battery very fast. But the only time i dont lose alot is when its on standby.
my battery is outstanding on v3. Id reset and and try again, or check your apps, something has to be up. :u
What do you mean reset? Like back to stock

I think he means go into recovery and clean cache and dalvik cache. Maybe even do a factory reset (however that will clear out your applications). Just make sure you have good backups before doing a factory reset.
That never hurts to odin back to stock just to rule out the ghosts and goblins. to me, it sounds like an app issue. How many widgets are you using that need to refresh? How many programs are open and active when you first start your phone? Are you using a task killer? Are you actually using the phone actively, or is it on "standby"? Answer a few of these to give us a better picture of your usage.
My battery life has been stellar.

thanks for the wonderful help and awesome insight..
Mine has been pretty good... I would recommend what swehes said.
I got pretty good standby time, but when I use the phone (such as calling, browsing web), battery drains super fast. I can have it last more than 4 days with light usage, but less than 10 hours with normal usage (no games, only texting, calling and browsing web).
Either do the process people are calling "recondition your battery" (charge fully, drain fully, charge fully, then immediately wipe your battery stats), or charge your battery fully once on an external stand-alone charger, then wipe your battery stats.
The battery profile in the stats file with the ROM just doesn't match your real battery's performance characteristics -- low charge point, high charge point, usage curves, etc. ... so it thinks it has juice when it doesn't, or it may shut down when you should still have juice left, etc.
My battery life has improved with every day. At first, when I cleared the battery stats in CWR, the phone lasted me around 36 hours. However, the day after it could not hold for more than 16 hours, but it has been increasing and now stays around 26 hours with my moderate to heavy use.
EDIT: Freezing Media Hub and the device management service in TB has definitely contributed to the prolonged battery life, I should probably remove it all together.

If you use Titanium Backup (I highly recommend spending ~$5.00 for a full Pro version) you can freeze the apps via the Batch operation.

Well i just conditioned my battery and that didnt help. So i'll try wiping the caches and then if that doesnt work then i will odin back to stock and fresh install it.
And i only have weather, the messaging widget that tells me how many messages i have and thats about it

reconditioning the battery is good to do but only gives a minor difference in how long it takes to drain. I already know it's an app problem. Open you're settings, go to applications, and select running services. What do you see?
Could it be device management?

If your rooted, try battery calibration. Plenty of threads about, and varying methods.
If not, another battery, and if new, ensure charge fully, phone off, overnight, before first boot.

forgot to mention i'm running [Rom]Wanam v3.2 at that time, currently on v3.4, the dark extended areas is me at work where i turn airplane mode on due to serious bad reception at work... sync is on rest of the time for gmail/whatsapp/kakao other than that manual updates on twit and some news apps...
u can see the first jump in the first pic, that was due to me exchanging with 1st spare battery( got 4 + original batt= total of 5)
i dont know if its the phone and exchanging batteries thats causing such high battery losses at the end of the battery life...
plus yesterday and the day before battery goes crazy when it reaches 30-20% and when i go for a restart to freshen things up... the phone wont switch on thinking the battery is totally dead... i put in the new battery and its @ 100% ... switch back to the old battery to see where the 30-20% went... it wont start...
now im thinking... keeping 1 battery in the phone with a charge from 0-100% actually takes the phone all the way to 0% but exchanging the battery wont...
how am i supposed to use the full potential of the batteries...

been using this app since my old sgs, it sure works and have been using it ever since...
tho in the [Rom]Wanam ... install procedure says that its backing up the battery stats and this lead me to think that a batt calibration is not needed... or am i wrong to think so?
If you change batteries, all previous data will be irrelevant, and you need to calibrate each time. You can do things manually by installing battery monitor widget, charge to 100% AND until the mA reaches zero (Voltage spills be approx 4200mV). At this point, quickly delete battery stats (menu / stats /) and immediately unplug.
https://market.android.com/details?id=ccc71.bmw
Top help with monitoring, You can config the update rate and widget content so it shows mA, %, mV. Also have alarm when stops charging (if configured).
There is also an option for calibration, but I only use this method when done above first. Never discharge to zero, 1% min.

Thing is, what's the use of having spare batteries if this will happen on each battery swap and having to go thru calibration means having a charger nearby...
and by 0% i didnt actually mean 0 but till that 1% turned the phone off
if what u said is true, then i guess i need some kind of script to help and keep the batt data even after swapping.. based on 1 good calibrated file swapping batteries should start from a certain point even if the batteries do lose some of their charge but continue to moniter things as they were... i dunno if what i said makes sense... correct me if i'm wrong
Not really 100% sure, but sure I have not always calibrated after a battery swap in the dhd..The previous battery was calibrated and performing well, and the replacement would have been very close to 100% charge. I didn't notice any irregularities in the battery data, or battery drain.
So I suppose a good bat stats file should help the phone showing relatively "accurate" data after a battery swap, if they're both "conditioned" (gone through a number of charging cycles, not straight out of thre box)
Maybe I could be wrong, but based on past experience.

Have you tried different radios/modems for better reception? if your phone is struggling to get decent reception its going to use your battery.
You could try changing to 2G only in wireless settings. used to help me alot.

Stock battery
I have done everything from Autostarts to managing my processes constantly. I played hanging with friends, got on here, and texted.
I posted an updated battery usage. I have lowest brightness, lowest image brightness, 15s timeout, etc.
i would probably switch to conservative governor vs powersave
This isn't typical battery life
I'd advice you to use better battery stats and cpu spy to se what's causing your battery to drain so quickly
Sometimes I notice "back up" in bbs, and this casus my phone to drain within a day
Hanging with friends does consume a lot of battery, but I play it too, and this does not cause that much drainage..
I have ICScrewed and with a heavy usage, my phone usually last for 1.5 ~ 2 days
With moderate call/text and idle, it lasts for 4 days.

Dang that is high! Are you sure about that? :O At medium usage /w unnamed i only get about 18 hours total. It was similar with ICScrewed too
Holy crap. I'll look into better apps. Could UnNamed be the culprit? Or the kernel?
Should I buy a new battery? The life waslike this for the few days I was stock, I think
I average around 17hr, on a good day I'll get 20h. I also recommend better battery stats, great app to see what's keeping your device from going to deep sleep.
Another great app is lbe privacy guard, you can deny certain apps and games some of the permissions they want (disabling GPS on those that really don't need it etc).
I'm on unnamed so that isn't the issue. Might be the kernel, just check the kernel wake clock in better battery stats to check. I'm on entropy's latest dd, while i do feel i got better battery life on the kernel with the latest unnamed ROM I'm not to sure if it's the kernel or something else.

I'd be curious to see your graph. My battery is dead now, but tomorrow I'm going to get on and upload Better Battery Stats to my phone. I would've paid for it on the Market, but I couldn't find it when I searched. I'm curious to see what other people think. I switched all Powersaves to Conservative. Is OnDemand bad for my CPU as it constantly trips from 500MHz to 1.2GHz? Should I consider going to 1GHz?

I have a hard time believing that. I've done everything I can to optimize my phone and reduce wakelocks and battery drain, and I still never get more than 20 hours on a good day, and that's with moderate usage.

I agree. This is my latest battery cycle of what I consider "moderate" use
What I'd consider light usage (about 10 minutes of voice, between 5-10 minutes of cellular data, 10-15 texts, and about 20 minutes of total screen-on time) I get about 35 hours.
I have managed to almost completely drain my battery in about 4 hours though... Thanks Game Dev Story!

I realized I forgot to turn off data when I'm not using it, but I installed better battery stats and I didn't really see any wake locks. Should I try a different kernel? Any opinions on an efficient one? NOTE: I already got the yellow triangle for using the Odin way, so I'm fine with doing whatever to this phone.
I added my better battery stats shots. I guess today would be called a very light to light day.

I see two very top wake locks have kept your phone from sleeping for an hour..
That is a significant amount.
Also, use cpuspy to see how hard it's been working.
I would try to get rid of those top two wake locks...
Oh crap! I didn't see them until you brought it to my attention. That explains some of the idle drain. I'll look into CPU Spy. You guys have been so helpful!
Your kernel wakelocks had no data, probably due to BBS being a fresh install. A full charge should set a proper reference point.

If something's holding that many log wakelocks, something might be spamming a log somewhere.
I can't find anything to help with those two either. Or would seem that the keyguard might have something to do with text messages, but I can't see anything that would spam the log. Where might I be able to read this log?
Also, I'll post my CPU spy stats toward the end of the night. It's looking like it spends most of its time at 500MHz.

I've seen a lot of users' postings of battery statistics (screen shots) and they are all considerably better than what I am getting. The biggest difference I see is in the amount of battery drain from "Android System." What I see posted is between 9% and 13%. However, my batt stats show the Android System draining 60% of the battery.
So, what am I doing wrong? I'm still kind of new to Android. Is it the widgets? I've checked running processes verses what apps are draining battery life and nothing is running that drains like the system does.
Further info: I am currently running the 7.18.12 build of Diet ICS, but I was seeing this behavior on stock as well. Some widgets I use: Astrid premium tasks widget, Evernote, doubletwist, slacker, 3D clock/weather, a widgetsoid switcher, and APW Calendar.

How often do your widgets that gather info refresh? Try scaling down on some widgets and see if that helps. If not, try to flash stock with odin and start over. I was having some problems with my phone when I first got it (MTP specifically) and I falshed stock and everything started working fine. Also, if you are using Google Chrome, make sure you have the experimental feature of using the gyroscope for tilt scrolling set to off....it is known to drain battery.
Hope this helps :good:

Maybe I will try flashing stock if I have time today. I reset my battery stats in recovery mode when I took the phone off the charger this morning, so we'll see how today goes.
I looked into the widgets and the only one that refreshes data on a schedule is the clock/weather. I'll try a different one or just not use the weather.
Great tip about Chrome. Didn't know it did that.
Do I actually need to calibrate the battery? I tried the method of letting it die and charge back up a few times and I've tried recharging once it gets down between 70-80 percents life. I'm not sure which method helped, but I did notice an improvement.
Thanks again for the help.

Never mind! Just searched" CPU sleeper" on the Play store and--voila!
On another note, I'm so glad I got a device with a huge support community. Coming from iOS, it's nice to feel part of a collective effort again and get such great advice. I know there are a lot of iOS forums and there is some great work done through those communities, but those seem so trivial compared to what is done through XDA and the level of helpfulness is unparalleled here.

I read somewhere in the forum that these batteries actually like to be constantly charged up and not let die completely. There was no explanation for this but I will research it because I am curious. With my old Captivate, i let it die then fully charge to extend the overall life of the battery.
How is your battery so far?

I've applied all the tricks folks have shared here and have flashed the Diet ICS rom. I am going to take screen shots of my usage data on a daily basis and see how things fair. I'll post my results here. Here is one from last night before really getting into all the tricks and the new rom. So, maybe this is my "before" shot in this documentary of a noob's journey to better battery life.

Have you tried using the CPU Sleeper app?
http://forum.xda-developers.com/showthread.php?t=1745516
I found that it does a great job of preserving battery life when the phone is in standby. I used to notice my battery draining really fast over short periods on standby (phone would be hot to the touch). After installing this, I have not encountered that problem again. I get 16-20 hours of use on moderate usage. LTE, gps, and sync are always enabled. I DO NOT have the phone in power saving mode and I seldom use wifi. I used to get 10-12 hours of battery life on the same usage before. I am running the rooted version of the stock rom from my carrier.
CPU sleeper app works great for me. I am in a non LTE area but get incredible battery life, last all day usually with around 50% left. An order of magnitude better than my SGS2

Have you tried using the CPU Sleeper app?

I found that it does a great job of preserving battery life when the phone is in standby. I used to notice my battery draining really fast over short periods on standby (phone would be hot to the touch). After installing this, I have not encountered that problem again. I get 16-20 hours of use on moderate usage. LTE, gps, and sync are always enabled. I DO NOT have the phone in power saving mode and I seldom use wifi.

I am using CPU Sleeper now, thanks to the advice of a previous poster on page 1. Good to hear it works for others.
I had the SGS2 as well and the S3 is definitely better.

Hi all,
I also notice this and this were the steps that I did and seems to help me to reduce this process to like 5 %. I'm on Sprint S3 but should be the same for the all carriers.
Go ahead and open Talk application. You should see your account in green (I'm not using this application) then hit the menu and then select sigh Off. Make sure that your account changes to Offline (sometimes it is change back it self so open one more time make sure that it says Offline). Then what else I change is in wi-fi advanced options: under Keep Wi-Fi on during sleep I choose Only when plugged in option. then I reboot the phone and from now on (almost 2 days) my Android system process show up only 5% of usage and my battery life improve significantly. I hope this will helps.
Thanks
Those are great tips. Thanks. I will say I've gotten increasingly better life since employing other tips discussed here.
Something else I did was download a profile changing app. I got Quick Profiles, but anything should do. If anyone uses anything better, please share. I have a profile for power saving that turns down my brightness, and turns off wifi and Bluetooth. The app will let you put shortcuts on the home screen to instantly change the profile. I'd like to find one, however, that will also turn off gps and mobile data.
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.
