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 all,
I love the Sony Tablet except its battery life. for something that is so huge compared to the others similar products out there, I am sure that they could have squeezed a bigger battery into the unit.
The power capacity is pretty weak. Let's hope that Sony offers a higher capacity battery size. I would gladly pay to upgrade it.
That's weird, my battery life is fantastic. If I play games on it all day it'll last 8-12 hours, but if I just use it intermittently and moderately it'll easily last me a couple of days. On standby it only uses a couple percent a day if that!
I'm the same as unclespoon. Even during heavy use, I get about 9 hours, which is way better than my old Galaxy Tab could ever muster. Standby usage is crazy low, its fantastic!
Not sure what you mean either about being larger than most other devices. The Tablet's 9.4" screen is smaller than almost any other full-size Tab out there (including the iPad) and since the back curves, theres not actually a lot of usable rear space (look at how thin its getting at the thin end, now imagine trying to fit a battery in there!)
I'm not sure you'll find a Tab out there currently with a better combo of size/battery life. The chunkier Toshiba Thrive will last longer, the thinner Galaxy Tab's will last even less, and my Tablet S always outlasts my iPad, so it might just be your device. Try checking Settings -> About -> Battery Use
I'm of the same opinion as the op. My tablet s has dreadful battery life and especially when it isn't doing anything. (50% usage is system standby) my old galaxy 7 was far far better (charged about once a week)
I believe this may just be because it is new (only have 1 full charge) as my galaxy s2 was initially unimpressive and then lasted 3 days of moderate use without charge. Hoping the same will happen to my s1.
Time will tell
My only guess was that you did a shoddy job of conditioning the battery. My old Galaxy Tab (the first 7" one) was hopeless, but when I replaced it, I conditioned the battery better and it was a bit better.
My Tablet S lasts for days and days and the standby usage is tiny. Check whats using your battery in the Battery Use screen and get back to us, we might be able to help..
I noticed advanced wifi lock was causing massive amounts of wakelocks (8 hours out of 10 according to the stats in settings/about).

I noticed that as well. If you have Advanced WiFi lock activated the tablet won't go into deep sleep mode, there of massive battery usage. I still have Advanced WiFi lock on my tablet, but only activate it when I need to download/update something that takes time. Otherwise I turn it off. It's not worth the battry drain.
Wow. Your battery life are fantastic. 9 hours? That's huge. I have not used my Sony Tablet till flat but given the rate of battery loss think maybe the most is about 5 hours which is similar to what many reviewers are saying.
Just can't imagine that those reviewers are so far out of the ball park compared to you guys. I am using juice defender Beta. Not to sure if its helping or not. But at least if I not using WiFi it shuts it off automatically.
My battery used to drain badly during standby. I found that the Friend Stream service was preventing the tab from sleeping. Killed the service a while ago and battery has been fantastic since. Pushed it to 3 days with light use. About 3 hrs of browsing and facebook. My battery level is at 68%, been off power for 20h40 mins, and used for about 4hrs today - facebooking, Internet browsing. Note that no specific conditioning was performed.
What are the settings that you have on your Tablet? Auto brightness, background sync turned off ?
how did you stop friendstream, and what the heck is it, did you just kill the process and it stayed dead? (sometimes as u know u kill process but it will come back).
Good question. What is the Android software revision now. My is Android 3.2.1 (revision 2)
I acutally just uninstalled the crap-app. nothing I use anyway. It is an app for facebook, twitter and other social networks. So just get rid of it. Uninstall and be happy
my bad. I confused the HTC name and Sony name.
Social Feed Reader was misbehaving. Once started it kept running... rather than dropping off to sleep (and into Cached Apps).
Something wasn't right so I force stopped it and it stayed dead.
An additional note - the Setup, Applications, Running Applications feature isn't 100%. Some background apps aren't displaying as running or Cached. Go figure.
So any special method to stop the social feed reader?
I'm getting those kinds of numbers on mostly auto brightness (and sometimes lower, at night), with background sync turned on, WiFi sleep policy set to default, and no battery monitoring or saving apps running. The only thing I did was single initial conditioning cycle and since then its been great.
Also note that software-decoded video files will take a lot more of your battery than the equivalent properly encoded file. I havent had any trouble with Social Feed Reader, but I never even set it up and judging by the many stories around here, I would uninstall it if you're worried about battery..

Hi, that's good to know. Thanks for sharing. Unfortunately think I screwed up the initial conditioning. so I guess I will have to live with the 5 hour battery of my Tablet.
Btw how do you do battery conditioning?

In Setup, Applications, Running Services have a look at the awake time (listed on the right side) of the running processes. You'll note that system processes (the ones with the Android icon) have been awake since last boot.... but you might finds others that are as well. I noted Social Feed Reader showing high awake time and decided to nuke it. Simply click the offending app. You'll be given the option to stop the app... which is what I did. It's an app so doesn't restart once killed. Hope that helps...
Final thought: at the top right of the screen there's a 'Show cached processes' option.
The could be an offending app in there. Kill any installed app you suspect might be a problem and see if that helps.
my battery life is excellent.

I am really starting to loose my patience with the prime, I have had it for a week now and its just been a very a difficult ride so far. Coming from the original iPad, I never had any problem with it. For some reason, I lost 20% of my battery just surfing the web last night, now I did not view any videos, I was just reading several online newpapers. 20% in an hour !!! what the hell is going on here.
Can sombody recommend me a decent battery monitoring app pleaase? otherwise, this thing is going back and then I will have to beg Apple to take me back.
How many things do you have syncing? Cutting down on that saved me a lot of drain. Also the app you use depends on what you're looking for.
Where's my Droid power seems quite useless on the prime
Better battery stats is good for finding apps with wakelocks
Current widget is good for tracking the current your tablet was using but I'm not sure if it works on he prime
Good luck!

What brightness was your screen set to? Did you have SuperIPS turned on? 20% seems excessive but having the brightness cranked up can noticeably impact battery life, and using SuperIPS nearly triples the drain.
FWIW I keep my screen brightness to about 30% most of the time and I surf the web for about an hour or two a day and I have been getting 3-4 days of battery life or more. I leave the tablet turned on all the time as well, and last night after 3 days I plugged it in because the battery had finally reached 50%.

My Battery Drain Analyzer is good if you want to see an ongoing indication of how much battery is being drained per hour. https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain&feature=search_result
However, in order to characterize your battery use as good or bad, we'd need to know the brightness you were at (as others have mentioned), whether you're running Flash on the sites you were visiting, what performance mode you have the Prime running in, etc. Too many variables.
I'll add that it's difficult to compare an iOS device and an Android device in terms of battery use, because the Android device is likely doing much more in the background. There's a tradeoff between functionality and battery life (and between functionality and simplicity, etc.), and of course in such an equation Apple ALWAYS opts for reduced functionality. That's not necessarily a bad thing, but it's definitely Apple's approach and has to be factored into any comparison.
I do burn about 15%/hour when browsing, on 30% brightness or so and in Balanced performance mode. I've found the Prime to be excellent in battery use everywhere BUT browsing--video about 10%/hour, email/ebook reading/etc. bout 7.5%/hour, etc.
Thank you all for your comments. My brightness level is set to 20% and gps, bluetooth all set to off. I am now using auto airplane mode app and it has significantly improved the battery life. I am also now using a fantastic app called android assistant and i spotted services that were running like google+ and google voice search which were consuming a significant portion from my battery.

The best battery monitoring tool I've found is Battery Monitor Widgit.
And I would highly recommend Tasker over any app that is dedicated to turning a single function on or off. If, that is, you are willing to learn to set it up. You can do things like have it set screen brightness to max when you start YouTube and set it back down to your preferred setting when you exit YouTube, turn WiFi or GPS on or off based on certain criteria, etc, etc, etc.
A simple free alternative to Tasker that I use is AutomateIt. The most rules are set on my phone to turn antennas on/off and manipulate volumes while I'm at work, driving, or at the gym. If you're looking to do more complex thing, Tasker is probably the better alternative.

Thanks for the tip about Android Assistant. It seems very useful!
However I would get rid of Auto Airplane mode, you don't need it.
Instead go into "Settings > Wifi > Advanced (top right menu)" and change the "Keep WiFi on when asleep" setting to "only when plugged-in (recommended)" or "never."
What this does is that any time the screen is off, but you are not currently downloading a file or app, the WiFi will be suspended until you turn the screen back on.
You can turn GPS off from the settings if you never plan on using it, and it doesn't make sense having an extra app running in the background that just duplicates functionality already found in the OS.
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

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.

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.
So I'm looking to try to get my phone running more efficiently. In respect to both battery life and overall running smooth. Honestly my phone just runs like crap... lots of lag (not horrible most times), and battery life lasts me to 5pm every day.
I have a feeling my biggest culprit is the constant running background apps. How the hell do I stop an app from always running? Things like facebook, scoremobile, wechat... and many more. All of these, I turned updates, refresh, notifications, everything possible off. I just want to be able to use the app when I open it. Yet even with turning everything off, they're still using up a ton of RAM and in the running apps list!
So I imagine things like this are my main culprit of poor battery life and performance.
Anything else I can do? Underclock?
Running CM10.1 unofficial P10 about to go p11.
Thanks!
buump?
Try a different kernel perhaps? Either that or play around with governors. Hopefully these can optimise CPU usage.
It might take a while to figure out how to balance CPU power with maximum battery life. It really is just about trial and error.
Biggest battery hog for me is the massive screen, so you could turn down brightness too. Google ways to save battery life on Android and see what the rest of the Internet suggests
Also try the app Wakelock Detector. (I think that's what it's called haha) see what is keeping your processor running and find out ways to stop processes eating your battery when it shouldn't.
Hopefully this helped some
