I've had the 3vo since launch and lately my battery does hella fast. Whenever I check to see what has been using my battery it always says 60%+ screen and never 10%+ of anything else. I always have brightness dimmed and screen timeout at 30 seconds. Any ideas?

i know what u mean, i had the same problem but it eventually improved a bit for whatever reason. I think the main culprit is actually a wake lock thats causing the ****ty battery, not the display itself. Do you also have a high awake time?
The display usage being that high is actually a good thing. It means none of your other components are draining your battery excessively. The screen uses how much it is going to use and can't really run in the background and kill the battery like the cell standby, media server, and android OS could. I get great battery life, during a 10 hour shift at work my battery drops maybe 30% if I'm getting a lot of missed emails, calls, text. My display usage is 85%.
A thing to consider is that this is a percentage of battery use, not a microvolt value, so it's not really that useful for diagnosis just identification. One thing you could do is click each item listed and compare time on and CPU times listed.
Do you actually let the screen timeout every time or do you manually turn it off? Do you spend a lot of time using the 3D feature?
Basically if your phone is dying fast and display is the highest consumer, it is probably dying fast because you are using your phone a lot.
It simply means that your actually using your phone. People with 30 display is pretty much sleep sleep sleep. I get about 3-4 hours of onscreen usage.

I had one device that would drain way quick...same situation as you, with only a couple hours screen-on time. 70%+ display usage...
I took it back and forced their hand to give me a new one.
It has been working a lot better, I still use the phone just as much but it lasts much longer. It may have been a defective battery but it's probably easier to just exchange the whole device.
Good luck.

oh yes, the old 'return it' solution. lol fail
I'm pretty well versed with most diagnostic techniques to pin down what was eating the battery; believe me I tried all of it.
Sleep time was good, no apps sucking cpu cycles.
When the display was draining 30% battery per hour I figured it was a faulty display or faulty battery. Easiest solution within 30 days was to exchange.
The new one works great.
Hi all, I'm new to this part of the xda forums as I had a nexus before, just got the upgrade to the Atrix, rooting,unlocking of bootloader everything went well but I just flashed Aura's from with feux kernel and im getting really really bad battery life, like I'm talking 4-5 hours. There is one process thats really confusing me, its just called "x" and its sitting there taking about 35% battery, my screen is taking 55% battery.
It's getting really annoying as my nexus used to give me about 12 hours and the only reason I moved to the atrix was to get the better battery life that I saw with all my atrix touting friends (they all had 1-2 days battery life) I'm about to flash homebase and see if that fixes it but I don't know whats going on. I have a UK MB860 and I used http://forum.xda-developers.com/showthread.php?t=1196747&highlight=t-mobile+root to root. Pleaseee can someone help!
X is the webtop and there is a fix somewhere for that (doesn't completely work). Just flash CM7 beta. Its much better than any other ROM and has the best battery life. Everything except the finger print scanner and webtop work.
Also I had really good battery on the Ying Yang ROM.
Speedily sent from CM7 Beta
I think I might give CM7 a go you know, I loved CM on the nexus, even after it killed the memory chips it was still good! Im going to try it, is it really stable?
EDIT:
since updating to CM7 and Wiping my battery stats I have some how gained 39% battery!

Try alien, i had some battery issues with some other roms and kernels and tried alien and all is good.This phone comes with an 1930Mah battery one of the largest i've ever seen and it lasts me 12 hrs on heavy use.
battery stats
I've had great battery life on the atrix, now I'm getting a good look at the atrix on the 4800mah battery. I'm a heavy user and I could not get over 24 hours. And now I have 59 hours and I have yet to actually see how far I can take it. Cm7 beta. Juicey....
I find that all gingerbread roms have horrible battery life compared to froyo on the atrix. Cm7 battery is worse but the phone is smoother. Faux 1.3ghz kernel has even worse battery.
Regardless of the radio or magical method of resetting the battery state you use.
1:25 screen time and at 47% battery. Been off the charger for 6:15. It will make it through my 10hr shift with about 20% remaining if I'm lucky, usually I just toss it on the charger.
Background data is off, email and social apps are manual sync and wifi is off.

one weird thing I am seeing is the display which is at 0% brightness is using 91% battery
Also the better battery stats app says my actual battery is 91% but the phone is reporting 66% I wiped thenbattery stats but nothing!

I was just about to post that lol. Also make sure every time you flash a new rom you are at 100% if not that is a sure fire way to cheat yourself out of battery life. I don't know if I'm just one of "the lucky ones" but I easily get over 16+ hours with moderate usage. I'm running CM7 beta with quite a few things frozen.
Ok so I followed the guide to perfection and it didn't improve the battery life one bit! I'm trying hard to find a t-mobile radio I can flash as I have read around it could be my radio that is the culprit and I am also getting rubbish HSDPA readings, I should be getting full bars but since switching to homebase Im only getting one bar.
Using watchdog I have noticed that the Xorg process is using over 50% cpu which does not seem right to be and I believe that because its a linux process Watchdog can't kill it. Is there anyway of fixing this?
1) Uninstall Tango, Facebook and Handcent SMS if any of the three are installed. They are huge battery drainers and you can find less battery hogging substitutes
2) Freeze any unnecessary apps, I believe there is a thread somewhere in the General section that has a pretty decent freeze list (if you flash CM7, you will have very little to freeze but that's good!)
3) Keep brightness down to a minimum when you can, I've noticed kicking the brightness up rather high can be pretty demanding on your battery
4) Set SetCPU Profiles to something like this...
Screen Off 216/216
Charging 1100/216
In Call 456/216
Battery <20% 456/216
Battery <10% 216/216
5) If you have the proper kernel set the CPU govner to power saver.
6) Undervolt, test yours and never apply set on boot unless you are positive it's stable, mine are something like this...
1100 MHz -50mV
1000 MHz -50mV
912 MHz -50mV
750 MHz -50mV
608 MHz -100mV
456 MHz -150mV
216 MHz -200mV
This way when you're phone is idling with the screen off, in a call or low on battery it is undervolting heavily to save maximum amounts of battery
With this setup I can get 30+ hours pretty regularly with moderate-to-heavy usage (weekdays/non-work days), 22-25 hours with more heavy usage (work days) and close to 48 hours with little usage (weekends).
It all depends on your usage and your phone but I have found this setup here to work fairly well.
I am currently on CM7 Beta, stock CM7 radio and stock CM7 kernel, running at 1100/216 when above profile conditions aren't met. 32% been running since 9 am this morning, it is now 3:15 am, today was a long workday.
I can almost guarantee (almost) that its your rom/kernel combination. Had same problem til I changed.

That will nuke your webtop & fix your problem.
I'm now using faux kernel for CM7 and that hasn't improved anything, in fact I think it it has made it worse. It's getting really irretating because using the watch dog app it always says there is one linux process on every rom I use that is clocking at over 50% cpu usage and It won't let me kill it (probably because it's a linux process), its really annoying me because all I want is my phone to work properly but to enjoy the full rooting experience. I know countless amounts of people with atrix's and they get a full day and a bit out of their phone with heavy usage i can't even manage 10 hours!

Watchdog eats battery like a mthrfckr, get away from that. Install BetterBatterStats instead & look for wakelocks. Which linux process are you noticing with that high cpu usage?
How many hours of screen time do you get in those 10 hrs?
Have you tried with a fastboot wipe & internal storage format prior to installing a new rom? Are you using the latest recommended radio for your phone?

Turn background syncing off if you are using that, and get in the habit of doing manual updates.
Too many times (with ANY Android device) people leave background syncing on and it tries sending/receiving data in a weak signal spot when you don't realize it. That's like a hot knife through butter on a battery.
Leave syncing off permanently if possible! That's a huge improvement right there for anyone...

Hey, so I've seen several people claiming fantastic battery life, etc. So, I am just wondering what's your experience in general. If you've got some free time and feel like typing, can you list several things like:
roms & kernel
stock/anker battery
battery life
screen time (and possibly voice call time or whatever else that seems to consume lots of the battery life)
highest battery temperature (I recently got pretty high so I was kind of worried)
and anything else you think might worth sharing (favorite actress? :silly
As for me, I recently installed Speed ROM 6.5 with stock kernel on stock battery
I only got 8 hours battery life to get to 14% with 3 hours of screen time (mostly used for game, browsing, and flipboard)
I got up to 100F (~40.5C) after playing a game for about 15-20 mins which made me leave it for a few mins to cool down. The next time I played the game again, it got up to 109F (~43.5C) after playing for 20-30 mins....
I am wondering whether that kind of high temperature is normal or not, and whether my battery life seems ok or bad; which is why I am hoping people can share their experience here. I haven't try using faux kernel though (might try it tomorrow in hope for a better batter life)....
So, again... if anyone got free time and feel like typing, please share it with me :angel:
From my g2 to this phone all I ever see is how bad the battery is. Never noticed a difference switching roms and battery across all smartphones I've used is allot what I expect.
Some people just can't be happy you know. Not to mention people never agree on anything (me included ).

Well, first off, I am not trying to complain about the phone here. All I am asking/trying to find out is whether my experience is "normal" or not for Amaze.
I also come from G2 and obviously the battery life will be worse on the Amaze in general. This phone is 1.5ghz dual core and 4.3" display compared to 800mhz single core and 3.7" display on g2 with only extra ~300mah on the amaze.
I just want to know if my experience of getting only 8 hours battery life (with 3 hours of screen time consist of game and browsing) and getting a high temperature of 109F on the battery is considered "normal" or not for this particular phone. I only have one phone here; so, I don't know if my unit is bad unit or if it is normal for the Amaze.
So again, by all means, I am not trying to complain about this amazing phone here. I am just trying to find out if this is what normally happen with this phone.
And yeah I'm one of those guys that can never be happy :silly:. When I used G2, I want larger phone and faster performance. When I got Amaze, I want slightly larger screen and much better battery performance. So, yeah I can never be happy with my phone :laugh:
The temperature thing is definately normal, it can get pretty high. I've had it go above 109f while on video chats on Skype. As for thebattery, that's normal too its just dependent on the user. U may have something that's running continuously in the background that your not aware of that's causing drainage. Many things that could be effecting the battery really

@OP, most likely you either have a bad battery, or your phone isn't sleeping properly on idle, or your phone has some problems with the RUU
Code:
Battery is ~1900mAh. If you use it for 3 hours active at around 400mAh, that is 1200mAh
700mAh left for idling the rest of the 5 hours. My idle current usage is around 9-40mAh as reported by Battery Monitor Widget(go to settings, change monitoring mAh to HTC Sensation to get a better reading)
700/5 = 120mAh/hour.... this means your phone isn't sleeping properly
Get CPU Spy... install it, then put your phone down for an hour without using it.... after that, does the report show that it goes to deep sleep?
When I got my phone and flashed the ENERGY rom, I had ~8 hours of total uptime (1-2 hours of usage)... i reflashed the RUU (do it on 100% battery), then it is better now
Now, on the Energy STOCK ICS rom with FAUX latest(0.12?)
Anker battery
15 hours of uptime
1-2 hours of screen-on time(roughly 2-3 hours of phone "awake" time)
don't remember battery temps, but i don't ever remember ti being that high
interactive governor, max frequency 1.4 ghz(to maximize battery life)
data on, autosync on, 2 gmail accounts synced only
My 100%->80% battery drains in 90 minutes, but after that, it slows down
I added the following to build.prop to tweak more battery life
Code:
# Power Save Tweaks
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
If you really want to stretch out the battery, change the governor to powersave(forces processor to 192mhz always), but it definitely lags and I wouldn't recommend it unless you really really need to max battery life
EDIT: Go to Settings->power->see what is using my battery, post a screenshot (this one is 16 hours plus ~2 hours usage)
see the part that says "awake", and the part that says "screen on"? It should be correlate mostly -> when you use your phone's screen, the phone is awake.... when you turn off the screen, the device should be sleeping and not be awake

I guess this phone is just that "hot" eh....
So, you're saying that I should be able to get a better battery life than that?
By the way, did you use Juice Defender or anything like that? Or did you just let your mobile network and wifi on all the time?

Hmm... I would try to check the stuff that you said. I did see the battery use like you did and I have much more awake (since I used it for games and browsing continuosly). But, when I was not using it, it doesn't show that many "awake" status which is why I thought that Amaze battery performance is just that poor. I forgot to try third party app like battery current widget or cpu spy. I will check those out.
Did you use Juice defender or anything like that? Or, did you just set them manually when you need it?
And I did leave my WiFi and auto sync on.... From your usage, I'd assume you turn off your WiFi when you're not using it, right?
Thanks for the input
Edit: So, I am guessing there's a rogue app on my phone? I just reboot my phone, leave it for a minute, and battery current widget shows 200mA on my notification bar
From what I'm reading your a heavy user. Like me lol. The most I get is 6-8 hrs. With 1.5-2 hrs screen on time. Comparing that with others who get double digits It's nothing but I'm a heavy user. I stream Pandora daily surf the internet for 1 hr non stop, xda for most of the time. . And on weekends I'll have most 4 hrs. But 3.5 of those screen on with data streaming and screen on with out going off. Kinda like watching a netflix movie on mobile network. I use my phone like if it is my laptop now. I rarely use my laptop. I don't have internet nor WiFi to connect to. But if I tether I would run out of data faster so I avoid it. Besides battery draining faster.
I think there is a difference between:
1. leaving the screen on for a while, causing the phone and battery to get hot. Specially when gaming because CPU is constantly running.
2. And total screen on time accumulated of 2-4 hrs screen on. Which is achieved when sporadically checking phone for text, calls, email, quick surfing. Then shutting of screen through out the day.CPU goes to deep sleep phone stays cool.
Now that's what I call a heavy user.
Remember when phone is hot battery drains faster so you need to find a way to cool it down. Sometimes there are settings in cpu apps that when phone reaches certain temperature that app will force cpu clock down a lot as to use less power to start cooling down but causing lag.
I've got a 4 month old stock battery with latest faux kernel v.16 with battery saving tweaks on it. Energy rom stock 8-1. If there is anybody that reaches double digits with 6-7 hours 4g mobile streaming not wifi at all. 2 hrs without turning the screen off not 2 total hours. Please say I? I'd really like to know your secret.

Battery Current Widget... go to the options (top right), change the current selection(should be first row, then middle row) to "HTC Sensation" (it'll be more accurate)
that program doesn't accurately report mA if you don't change it(before changing, it'll be screen-off deep sleep 100mAh, but after switching, 10-40mAh)
I don't have Juice Defender on... autosync and data is on all the time
try w/o wifi on... i think wifi should take less battery power than data, but it always depends
on my screenshot, if you go back one and click on the screen-on... what does it say?
what does CPU Spy say about your phone going to deep sleep?

if you are only getting 8 hours uptime with 1-2 hours of usage, then your phone's not going to sleep properly... I'd reflash the RUU, then flash Energy ROM and faux kernel... i had that problem before I reflashed RUU (but that was before I knew more about CPU states and mAh usage on this phone, so I don't know if it was a problem with the deep sleep, or the phone not properly updated to ICS when I got it from someone else)
you want to try to max battery life? I can give you hints to hit that mark... it's all about physics/electronics
your battery is 1900mAh.... Using Battery Monitor Widget(with the Settings changed to detect the phone as "HTC Sensation", see above)
With the tweaks in my first post of the build.prop, BMW shows my idle around 10-40mAh..... 10 hours of idle = 100-400mAh. Note, this is with sync and data on... if you use Juice Defender or data off, probably less
So, idle, you use up 400mAh... you have 1500mAh left
1500mAh / 6 hours = 250mAh each hour.... with BWM, it shows that the current usage goes between 100-500mAh depending on how much screen brightness, data used, processor speed... If i choose powersave, I think it goes between 50-300mAh, but its really laggy, noticeable
300mAh * 6 hours = 1800... close enough
to avoid the 100%->90% fast drain, employ bump charging:
either
1) charge your phone to 100%. remove plug, wait for it to drop to 90%. replug it, charge to 100%... repeat for 5-10 times
2) charge your phone to 100%. remove plug, shutdown. Replug it, wait till the light goes green, boot up, charge to 100%, remove plug and shutdown, replug it , wait till light goes green etc.... do the cycle for 5-10 times
I was trying to see how much I could get out of my phone. I used my phone as little as I could, putting it into airplane mode when I slept.

unfortunately, for this device, the screen brightness and dual-cpu takes up a lot of power... if you see the pic below, when you use your phone(screen-on/awake), the battery % left has a sharp drop
I know for my old phone, LG Optimus T, I didn't have a data plan... the phone had data off all the time, and I got days out of using it(phone calls, wifi/browsing, checking gmaps offline)... once I enabled a data plan, it got half (like 1.5 days instead of 4)
if you calculate your usage... its possible
24 hours * 50mAh during idle = 1200 mAh
2 hours * 300mAh/hour during screen-on usage = 600mAh
total = 1800mAh, the capacity of your battery

to avoid the 100%->90% fast drain, employ bump charging:
either
1) charge your phone to 100%. remove plug, wait for it to drop to 90%. replug it, charge to 100%... repeat for 5-10 times
2) charge your phone to 100%. remove plug, shutdown. Replug it, wait till the light goes green, boot up, charge to 100%, remove plug and shutdown, replug it , wait till light goes green etc.... do the cycle for 5-10 times

So if I use either of those 2 methods above, is my battery 'cured" of the 100% to 90% fast drain? Or do I have to keep doing it over a period of time?

bump charging only helps you for that one time... you have to do this every time if you want max battery capacity
the problem is 2 things
1) the hardware/software is configured to maximize battery lifespan, meaning to slowly charge it and not go to 100% (high voltage, damages battery)...
2) the hardware/software is poorly coded, can't read the battery voltage properly...
either way, doing this means you are forcing current into the battery every time... your battery will hold less charge in a few months if you force it to full everytime... so you have to get a new battery aftera couple of months or live with lower capacity
I will just try to observe it better tomorrow using all those apps. With much less usage (1.5 hrs of screen time), i only got 11hrs of battery life. The screenshot below is for those 1.5hrs f screen time... I dont use jd and got email sync every 1 or 2 hr though....
Sent from my HTC_Amaze_4G using xda app-developers app
I tested the idle-deep sleep capacity of the phone...
got 21 hours idle, 17 minutes screen-on (minimal use of phone) with 50% left
here is my phone with data and auto-sync ON, I got roughly 10 emails(all received during different times), had about 10 minutes of phone calls
NOTE: around the first part of the graph, you see the %-left spike up... I rebooted my phone then... and you can see that the battery-monitoring software/hardware part recalibrates itself to the real value
NOTE: cell standby-time of 21 hours used more battery than screen-on of 17 minutes.
When I used the phone for another 15 minutes, screen used 35% of battery while cellular standby dropped to 22%
tl;dr, using the phone, especially the screen, kills the battery a lot more... not using the phone = lasts a long time

I guess after using all those apps that you mention, I can kind of see that Amaze battery is just way worse than my G2. I was pampered with my G2 battery life for a week and now I realized how bad Amaze battery is. lol
I got 11% left after 12h 15min. That's about 1550mA used (I use stock battery).
almost 3 hours of screen time (3*350) = about 1050mA
25 mins of phone call = ~120 mA
about 8h 45 mins of idle = 360mA
So, yeah, it summed up about right this time (more accurate compared to my first result where I think I got a rogue app)...
**I am eagerly patiently excitedly waiting for a fully working stable CM9 by sport :angel: **
On a side note, just wondering if anyone know if galaxy s2 have better, worse, or about same battery life? I am just curious since s2 is supposed to be amaze rival at t-mob....
Here's mine
Rom: Fourth Bar Jellybean Fusion
Kernel: Faux's Kernel, latest edition [August 15th]
Average Temp: high 90's
Average Battery Life: 5-6 hours.
Realize that what you do with screen on makes a significant difference- If I play organ trail(awesome zombie game styled after old school oregon trail game) I can play for a long time with little battery drain.. but it is a 2d game, and not going to be very processor intensive. If I play final fantasy 3, a 3d game, wow.. battery will drain much quicker, but then again, it IS a 3d game, and processor intensive. So HOW you use your phone is even more important than the screen on time.
With the latest faux(17) kernel, and 2-3 hours of screen on, the last few days I have 45% battery left after 15 hours since unplugged. Maybe 30-45 minutes was organ trail, but not much other gaming. The only changes I made, were made to the kernel, which I posted here(be aware that making all those changes will create some small lag changing screen orientation or opening app drawer, but haven't noticed anything else). http://forum.xda-developers.com/showpost.php?p=30298629&postcount=4
I also underclock to 1.2ghz- this doesn't create any lag, and no game or app I have used seems to work ANY better @1.5ghz than it does @1.2ghz. The main difference is the voltage it uses at max speed will be less @1.2ghz.
If you have weak 4g signal, there is an app i recently posted in some thread that puts it on 2g while screen off.. that has helped a lot too. If you have constantly good signal, then it won't make MUCH difference(tho 2g does drain less than 4g even with good signal), but it takes up to 2 seconds for it to switch to 4g after screen on. I can wait two seconds before opening an app, I don't care.
I assume you have used betterbatterystats to see what apps keep your phone from deep sleep, under partial wakelock?
And when I get obnoxious drain, but NOT because the phone isn't going into deep sleep.. I turn on the logging of an app called currentwidget- it can actually measure the MAH used while using specific apps.. the app itself can cause a bit of drain, but you'd only use it long enough to see what app is so battery inefficient. I have more about how to use that under battery savings part of the bible in my signature.
Edit: And I consistently get battery temperature of 77.7-77.9F, I always have, no matter the kernel or rom or settings.. perhaps it raises a TINY bit when I play some intensive game, but never noticeable. I am using an anker battery tho, so if you are using stock, perhaps that is a factor.

Good to know that. I used a different app to check the current mah and it seems reasonable. I forgot to use better battery stat; but, based on cpu spy, the deep sleep time seems about right... I haven't updated my kernel to v17 (still on v15) and haven't done any edit that you mention since I was still switching roms to find the ROM that suits my need. I might try to do those stuffs today and hope for the best.
And btw, I am kinda jealous with your battery life... 45% left after 15 hours unplugged and 3 hours screen ON
I might get similar result; but my battery left will be 10% and those screen on are mostly on flipboard, xda, and browsing....
Like right now, 6h 10min unplugged, 40 mins of screen on (xda & flipboard), and I am down to 66% :crying:
**On a side note, I just get my hand on gs2 and I am just curious to try and see how good it is since gs2 seems to be such a hyped up device compared to amaze.... :laugh:

Just checked my usage. I'm sorta similar to yours in terms of screen on time. 11 h 43 m since unplugged, 39 min screen on (facebook, news, texts) and I'm down to 62%. My screen on time isnt that high, yet something else is draining my battery.
Awake time is 1 h 44m. Lots of Alarm Manager partial wakelocks. need to figure out what's causing those
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.
Sent from my GT-I9000 using xda app-developers app
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.
Sent from my GT-I9000 using XDA
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.

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.
