Hi all, I recently switched from stock roms on my fascinate to a couple different voodoo based ones (evil, community rom) and since then I've had a huge decline in battery. When I check usage stats the display is causing 80-85% of it. I have it set on the lowest brightness and it doesn't make a difference. Could this be related to voodoo being enabled?
Unlikely, sounds like you might have an app keeping it active. Voodoo changes the file system, should no cause an issue with the display.

It depends if he is using any of the voodoo kernel, which would impact color, sound and so on.
It is said to have impact on battery life while on voodoo.
voodoo or non voodoo display will always be the highest use of the battery. I've not noticed any difference in battery I get on average 30hrs of battery life no matter what

Thanks guys. I'm pretty certain there's no stray app causing the drain, I've tried closing out all processes for a day and barely using phone or data and it still says display causes 85% of battery drain. Is there any other possible explanation?
Honestly, compared to other things, your display drains alot more power than anything. I have had my phone in standby all night and it will still show display as using the most power, I run mine at 0% brghtness most of the day(because I am mostly inside) and no matter what mine always shows 80% or higher in Battery Stats.
I may be completely wrong on this but based off other discussions on this same topic. The answer seems to be the same. That the diplay compared to the phone process and so forth, will always be a bigger drain on battery life.
Hope this helps.
Its normal for the screen to be the highest. If you are getting decreased battery life then first thing to try is resettimg the battery stats and recalibrating. If that doesn't work then you'll need to take a closer look at cpu usage.

Hi,
I'm currently using JuicePlotter to see how my battery drains over time and this past night I think it drained more than it should (or maybe not).
For the ones who don't know, JuicePlotter runs in the background (of course) analyzing your battery, that too wastes battery juice of course. Thought, the app dev says on his website:
Perhaps the most important feature of JuicePlotter is that - unlike all similar apps and widgets - it's very battery friendly;

So I'm not sure if the problem lies on JuicePlotter or not, I'll have to test it one night without it...
This is how JuicePlotter displays it's graph:
The coloured bands along the graph show your screen brightness, radio usage, charging status and battery temperature. Just scroll around to find precise information and make sense of the different colours.

I went to bed at 4:10 with the battery at 97%. Around 13:00, it was at 89% and I didn't receive any calls/messages/mails/whatever during the night. The WiFi/3G was off all night along with the screen of course. The battery temperature remained the same too. I don't know if it makes a difference but I normally turn off Auto-Sync if the WiFi is off too.
Is it normal to lose 8% of battery juice in 9h in standby? I think it's a bit too much, but I don't know... Does the same happens to you too? What else cloud it be?
Interesting looking app. I've never noticed much of a lose overnight. Just installed the app, will fully charge and give you an update tomorrow.
Also how's the cell reception in your area? I've heard it can drain the battery a far bit if the reception is low.

I'll have to do more testing but I think it's the app's problem... Tonight, I went to bed with 83% and it was exactly the same when I woke up...
I fully charged mine last night and turned on JuicePlotter. Still showing 100% this morning. Both in the app and on the phones battery indicator (in the notification bar). Do you know of any other apps similar to this that could be run in tandem?
Weird, Battery Graph also does the same thing...
This needs more days of testing on my part...
My battery goes from 100% - 0% in about 16hrs... doesn't matter how much I use the phone or not.
I have BatteryGraph but the results don't really mean anything to me as it just shows battery life vs time on a scale.
I'll try JuicePlotter to see if I can pin down exactly what's causing my terrible battery life.
I have a feeling it's running at full speed even when in standby but I'm not sure how to check if this is the case. Any ideas?
EDIT: Looking at BatteryGraph I've lost 15% in around 1hr... nothing unusual going on with my phone that I know about... just standard stuff running in the background. Perhaps the battery itself is simply past it's best.

Wow that is terrible, try apps like Taskpanel and when you add programs to your auto kill list the program kills the programs as long as they are running in the background when the screen is off, however if you are on lets say your browser and you don't go to your homescreen the screen goes off into stand by it will not kill the app. Also try draining your battery to the point it shuts down by itself, plug it in let it charge for a bit, boot into recovery wipe battery stats start up the phone or leave it off (your choice) and let it charge fully. Are you using setcpu or OC Widget or anything? If you are using SetCPU make a profile for when screen is off and make it underclocked like 264 Mhz to 480Mhz, or with OC Widget tick the 'use different screen frequencies' (don't remember what it is called since I don't use it) and do the same; I like SetCPU better because when you turn the screen on it switches profile faster where as OC Widget takes its time however with SetCPU do not use the widget it will cause Sense to FC and I'm not sure about Vanilla.
Hope this makes sense since all my ideas are said at once.

The way I've learned to recalibrate the battery is to let it go down to 5%, boot phone into recovery and wipe batterystats, then power off the phone. Let the phone charge until the green led is on without turning it on. Then turn on and use the phone as usual. Learned it over at modaco. Worked as a charm, and batterytime was improved. I have personally experienced strange batterybehaviour after periods with flashing a lot of roms.

Here.
That's interesting...
Cause I've been playing with ROMs latetly, creating my own, testing hacks and stuff... And most of the time the phone is plugged and the battery is charged, during the flashing process it's using the battery and then it charges again. I also have to leave from time to time and when I get back I continue my stuff, meaning I'm charging the battery at high levels.
I'll have to try that calibrate method...
For now, for the past 2 nights, with JuicePlotter off, I've noticed the battery level did not change at all during the night. Tonight I'm going to try one more time with JuicePlotter on...

Wiped battery stats at 5% last night, let the phone die and then charged whislt off until green light came on. Been keeping an eye on it all day and there has been a noticable improvement.
The phone came off charge at around 2am (so around 12hrs ago) and it has only lost 20%, which is a lot better than I was getting before.
It was probably just due to me messing about with some many ROMs and update zips lately as I tend not to have too much crap running in the background (I use OSMonitor).
I will look into setCPU but I remember trying it before with VR12 and it ended up causing some weird problems meaning I needed to do a full wipe to get everything working again.
Thanks for the help
This night, with JuicePlotter on, I only lost 1%, seems reasonable now... I don't know why that one time I lost 8% during the night. Maybe an isolated case? Something was probably running when it shouldn't, I just don't know what.
I have a Thunderbolt running Das BAMF Remix 1.6.3 and Imo's 2.7.0 kernel (I have tried going between Batt Saver/Normal, and now I am on Extreme). I adjusted my brightness of my display to about 20% (instead of automatic), and when I am home I try to be on my Wi-Fi. For some reason, I am not getting a full day's charge out of my Thunderbolt (when I first got the extended battery, I was getting at least 32 hours). I read about people's batteries and I feel people with the stock battery are getting more/equal amount as I am with an extended battery. I tried running Normal setting on Imo's kernel at one point and I did not even last 12 hours, and I was on 3G doing only minimal texting. I tried Batt Saver, and the first day I used it, it was really good (about 10 hours and I was down to 75%, but until I got to 18% or so and then within 3 minutes it was dead, which was weird). But the following day it was not as good as it was, and it died again less than a day. I even tried the Das BAMF kernels and they have similar results. I am also trying to switch between InteractiveX/SmartAss/OndemandX, but I am not seeing too much of a difference (unless someone can give hints on which is supposed to lend to a longer lasting battery). Any advice would be appreciated! (And if you need more specs on my phone, let me know... I generally only text, I do not play games or do very intensive internet things).
I have found the best battery life on bamf stripped v1.1, I get better battery life on that than any other Rom I've tried including stripped v1.7 and all the other bamf versions. I'm running the 4.4.6 kernel, I haven't tried the batt saver kernel from Imoseyon yet. I get 2-3x's the battery life as stock and almost twice the battery life as any other bamf Rom
There are lots of things to consider about your battery life. If you look at your batter use on your phone does it show anything that might be suspiciously draining battery more than normal? If you're using Imo's kernel you can type "12" into the terminal when you are changing governors to see the stats of how long your phone is staying at different frequencies, does it show a high amount of time spent at the higher frequencies? How long does your phones display stay on for?
There are so many things that can drain the battery its ridiculous and randomly I will have severe drains at times that are only solved by a reboot.
eraursls1984, do you have an extended battery? How much battery life are you getting?
Beastclaw, battery use seems normal - nothing out of the ordinary or suspicious is really eating at my battery. As I said before, I am currently running InteractiveX and at Extreme mode, and these are my states at different frequencies:
245760: 2102206
368640: 409810
768000: 58113
1024000: 263351
1222400: 12737
1408000: 72575
1593600: 0
1766400: 0
1920000: 0
Seems that nothing is really running too much on high frequencies, mainly on the lower end. My phone display is supposed to stay on for, I believe, 2 minutes, but whenever I am doing using it, I always lock it.
I heard Autostarts was a good app that could help with battery life and performance (and I was warned to not change any system settings), but I am trying to see if maybe there is anything else I can do to figure out why my battery seems to not last as long as other batteries.
You can try using an app from the market called "CurrentWidget" It allows you to log how much power your phone is using at different intervals of time. My phone generally runs at 40-60mA when the screen is off and its not doing anything and between 400-600mA when the screen is on and I am running tasks. You can use the log to check to make sure your phone isnt drawing too much power in the down state. It even shows you the stats in a nifty little graph form

I have a stock battery and with normal use I get 12-14 hours compared to about 4 when I was completely stock. When I use my phone heavily, constant browsing, I get about 4 hours compared to less than 2 stock. I always have my brightness all the way up except for when I'm in bed because this screen is not bright at all compared to my old phones. Unless you just have to have sense (which to me makes no sense, lol) then I would recommend trying bamf stripped v1.1. I am also not overclocked, I noticed a little increase in performance but not enough to justify the loss of some battery life., however I was going to experiment with it again since I haven't tested the performance and battery life of stripped v1.1 overclocked.
I mean, I have BAMF Remix 1.6.3, which I guess has Sense elements since I do not have BAMF Stripped? I mean, I do not think I use any Sense features or anything like that, so I have no reason not to get BAMF Stripped if it helps increase performance/battery life. Yeah, on Remix 1.6.3 and Imo's kernel at Normal, I had 12 hours on my extended battery... Haha.
Bump - does anyone have Autostarts? Or any other program/app that will help with the battery life, or any other suggestions? I will test the CurrentWidget app tomorrow when I am actually up and using my phone and see if I get similar results or if I find another program is using up my memory... I also recently installed Advanced Task Killer today to help with this battery problem, but I heard mixed things about using it and how it can actually negatively impact the phone instead of helping.

Before 2.2 they were useful on some phones if used right, but its not needed nor does it work on the thunderbolt. If its set to autokill then it will drain the battery faster by running and killing apps, then the phone using juice to reopen the apps that were killed. If you root you can use autokiller (not a task killer) to set parameters for ram memory but I haven't found it to be necessary on the t-bolt, it was needed on my old droid X to keep it from lagging. I would suggest uninstalling the task killer.
Took your advice and uninstalled the task killer - thanks! Anyone else have any other suggestions or advice about my battery problem?
Autostarts is definitely worth $1. If you are familiar with Windows, it's kinda like msconfig for android. It prevents nonessential apps from starting in the background and wasting battery & network bandwidth. If you want to do everything you possibly can to minimize resource hogging, you should get Autostarts.
I downloaded Autostarts - I hate to be asking this sort of question but I am sort of cautious when changing these sorts of settings (because I heard a person who had to boot into recovery because he shut off system applications by accident), which programs should/shouldn't I turn off? I am a little confused how to use this program - did it automatically shut off some programs, because as I look through I see some programs are crossed off in a green line... Any help would be appreciated! Thanks!
Bump - can anyone help me with Autostarts? Any help would be appreciated! Thanks!

Sigh, Autostarts isn't a "task killer"
I stay away from any proccess that's needed to run in the background. Things in yellow, leave alone. IMO pandora has no business running in the background at start up. If there's no valid reason, I kill it.
Tossed from my Tunabowl
I realize Autostarts isn't a task killer (it cannot kill a task if it never opens up, hehe). Thanks for your advice though! The more I was looking at it last night, the more I was understanding, but you just reassured what I was assuming. Hopefully this helps my battery a bit... Or I figure what else makes my extended battery drain faster than others.
Even with Autostarts, my battery life has not improved that much... I have been experimenting a bit with different governors and settings, but now I am back with the extreme Imo kernel and on InteractiveX. Does anyone have any other suggestions? Any help would be appreciated!
I was having trouble with my battery also. I've been lucky with Gingeritis but still the battery was killing me. This may not be an option but the extended battery is amazing. I got the case to go with it and I'm not disapointed. This OS with heavy use also and display at 50% and all animations enabled. Also running 4g all day!

The problem is, I DO have the extended battery and now seeing some of the battery life that others are getting (a lot say 30+ hours, I am barely pushing my phone and I am getting less than 20 at a time).
BAMF 3 RC2, imo 3.3.4, 245/1593, LTE Only mode, auto brightness, twitter sync every 15 minutes, facebook every hour, gmail push, weather every hour, 4 hours of music streaming, another couple of playing, a lot of twitter and facebook, and doing a bunch of other things with the phone, and I rebooted about 3 times. I think I could hit 50+ hours if i didn't OC or reboot.
Oh yeah, I have the extended battery
g00s3y, which governor are you using?
i'm on the same kernel, but using gingerremix w/ a std battery. the phone drains 40% overnight with it being on wifi. (that's with just gmail pushing and gtalk on).
Hi. I know there are tonnes of battery related threads out there but I would appreciate if I got some personalized help.
I am running Trigger 3.2 Final with Bali v1.8.4 and the JK6 modem.
I have gone through all the modems available for Froyo and JK6 gives the best battery life for cell and data. No overclocking or anything.
The problem is I get extremely bad battery life on data on all modems. JK6 seems to be the best of the bad. With data off, I can get 20+hrs with light phone usage, but the moment data is turned on, the bat percentage just drops like a rock. If I enable data and browse the net with Opera Mini (no flash), a 100% charged battery can be reduced to to around 30% in around 1 hour. Sometimes more, sometimes less.
If it is the battery needed replacing, why do I get excellent cell life with no data activated. Bali is supposed to be battery efficient, but I am bleeding power. I bought those cheap knock off batteries from ebay and get the same results.
Brightness is on lowest, syncs are all off and email checks every hour I think. Nothing else I can think off can be chewing the battery.
I have calibrated the battery many times and makes no difference. I should also mention that I had worse battery life on the bionix roms.
On battery use,
Display takes up around 83%,
Cell Standby 11%,
Idle 5%
What can I do? Is there an app that will tell me if I should replace my battery or anything. I am all out of options right now
Bali Is The Problem
I just read about this same problem from other users, the Bali kernel eats up a charge cycle extremely fast and has even caused major over heating problems!
My suggestion is to go to a different kernel or change the ROM completely to something less power hungry
it could possibly be the batttery itself, mine did this a while back and replacing it helped, maybe even upgrade to the extended battery if a little more bulk doesn't bother you it's a great option try a different kernel, i use Bali and am not overclocked with the JK6 modem and text all the time at school I then got an iPod touch and stopped using my phone for music and it saves me an average of 30% battery 0_o idk why but oh well
finally found a thread on this issue after posting

sorry mods, pls delete
Me too ... it's driving me nuts.
I am experiencing this. My battery life is horrendous. Even when I barely touch the phone the battery drains extremely quickly. I have already rooted the phone with a few different roms with the battery setting "fix" to no avail. I'm on at&t. I have disabled wifi and gps. I have tried to use both the stock app killers and 3rd party ones recommended by these forums. My battery monitoring apps (both stock and 3rd party) consistently attribute the battery loss (always more than 90% of battery use) to an android system app. The android system app or file changes from day to day seemingly randomly. Files have included: UltaCfg, com.samsung.app.playreadyui and security storage.
Any help will be extremely* appreciated. I love the phone but it is nearly useless in this state.

I am draining my battery as quickly as I can (streaming Netflix through 4G LTE with max screen brightness, max overlclock w/ performance gov) and then i'm going to power off and do a full recharge. this seemed to have fixed similar issues in this thread:
http://forum.xda-developers.com/showthread.php?t=1756776
let you know the results.
edit: suppose i should say that i was not experiencing this issue until i updated KT747 this morning.
this is what i did:
1) drain the battery completely. let the phone die.
2) charge to 100%. do not power the phone on until it is completely charged to 100%.
3) when i powered the phone on I was at 99%. i plugged it in and it went to 100% in about 2 minutes.
this seems to have completely solved my problem. the android system has gone from using 57% of the battery to 6%. it seems like the kernel i was using vastly overestimates the percentage of the battery to allocate to the android system until it "learns" the capacity of the battery

I am also a Telus user. I had big time battery drain issues even with trying everything: enabling power savings mode, running Juice Defender, using wifi more, using darker wallpaper, keeping a closer eye on syncing operations, screen brightness and some other stuff.
After about 10 days I went back to the vendor (Futureshop) and convinced them to give me an exchange on the battery. They have a 14 day return/exchange policy for cell phones if you are not completely satisfied. I took some screenshots to argue my case. Thankfully the rep said ok and further explained how much power an AMOLED screen uses. I really didn't want to convince him that I am quite informed on battery drain issus and took the new battery and ran!
Conclusion is the new battery is so much better it's like night and day. I have the capacity now that others have been raving about.
If you can exchange the battery, do it. Then get the new battery and charge it up fully first thing.
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

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.

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.

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.
