I have had my Galaxy S for a bit over a week now and am pretty disappointed with the battery performance. Most days I take my battery off the charger at 7am and it reaches 15% low battery warning by 1-2pm. I do spend a fair amount of time reading XDA and listening to music. I'm currently running Stock JM1 firmware with no lagfixes.
Here's a list of my apps that I have installed:
http://www.appbrain.com/user/Lokhor/apps-on-the-samsung-galaxy-s
I am running JuiceDefender which I thought would make a big difference and does not. I have also set Tasker to change the Brightness level to 20 (below the safety threshold) when the battery reaches 50% or below, otherwise the brightness is at the minimum (30%).
I have heard that you need to condition the battery so I have been trying to do this but it doesn't seem to have had much effect. Today I used my phone only casually and it's currently at 22% after 12.5 hours. The battery use details show the following:
Display at 56% being on for 2h22m and 13s.
Cell Standby 18% Time on 9h21m, time without signal 13%
Phone Idle 7% Time on 7h33m
Android System 5% CPU usage 23m39s CPU foreground 24s
Android OS 3% CPU Usage 13m 27s
Is this normal? Is there anything I'm doing wrong?
Please help
I don't know what others are telling you about conditioning a LiIon battery but you don't have to. LiIon batteries don't suffer from what NiCad do. Some do suggest wearing the battery down to nil and then charging it up again. However, this is pretty bad for the battery and should not be done more than once every 30 cycles. With every LiIon battery I've ever owned I've either trickle charged it or charged it when it wasn't too low and they've all lasted over 3 years. I've never conditioned one.
Anyway, my advice to you is to see how long your battery lasts in standby. Mine could probably last 3 days or more if I don't bother it too much (with sync, wifi and all that good stuff). I find the worst contender for battery drain is the display. The only problem I see with your stats there is that I've played Asphalt5 for around an hour and a half which is quite heavy on juice and it only drains roughly 10%-15%. Then again you're browsing the web so maybe probably worse.
Oh, and when charging your phone, don't use the USB hooked up to a computer as it doesn't stop charging when it's full. Use the wall charger to charge.
no need to worry more

I found that charging it whenever it was convenient instead of when it was low would result in a charge that lasted ~24 hours.
I've noticed significant increase in battery life since I started waiting for the 15% charge warning, plugging it in till it was full and then unplugging it. I get 2-3 days of use this way.
I also set my email to only sync between 6 AM and 11 PM. I believe this helps a lot as well.
since we are about this topic, check this out
How to spot fake battery vs. OEM battery: http://forum.xda-developers.com/showthread.php?p=7953322
so if I'm listening to music during the day at work should I have my phone plugged into the wall charger or just let the battery run down?
Last night I took the charger off at midnight when it was full and when I woke up it had only dropped 5%. After reading my emails quickly it was at 93%.
it works fine either way

I find leaving the brightness on automatic uses up loads of battery. Setting it to lowest seems to make the phone last 24hrs+
I also found that having beautiful widgets clock/weather installed used up a lot of battery for some reason.
I don't use weather because it has to sync every so often to update it which to me is a waste...I'll just look outside. I also leave brightness on the lowest setting wherever I am as the screen is already very bright (why waste battery?).
My experiences with my SGS have taught me to be conservative with its battery. Anytime you turn the screen on, you eat power like crazy. The best bet is to just top her off whenever the need arises. Personally, I have found that I'm fine just topping her off in the car when I'm driving, so that I start my work day at high 90's, and especially once I've got my morning browsing out of the way, I don't eat a big chunk of battery at any other time.
But yes, if you find you are running low, you can happily just take a half hour to charge from a USB port to give you an extra boost. Alternatively, spare batteries and so forth do the same thing, although it can be annoying if you don't have a charger that will do the phone and a spare battery at once.
im experimenting with apndroid now to turn of 3g then i dont specifacly need it. It comes with an on/off widget. Looks promising so far. 40% at 2300 hour and then i have used wifi a bit, played angry birds and talked for about 2 hours in total.
Does anybody experience a 3% to 5% battery drain just a few minutes after charging the battery to 100%? It has already reached 100% so I already unplugged it from the charger, but then I noticed after a few minutes, it went down to 97% already, and then in 10 minutes, it's already down to 96%. In 3 hours, it's down to 84%; in 7 hours, it's down to 38% and that's just on standby mode with Wifi/Bluetooth OFF, 3G OFF, GSM only. I've been experiencing this problem for the past few days now. I've already conditioned my battery, charging it to a full charge (100%) after draining the battery until it shuts the phone off. I only charge the battery while the phone is off and usually it takes about 3 to 4 hours maximum to charge it to 100%.
The longest time it reached was 12 hours (battery unplugged from charger) and that is with light use, such as Wifi is only on for a couple of hours, so basically just 2 hours web browsing and skype, 10-20 text messages and 30 minutes to 1 hour browsing the photo gallery or watching videos. No phone calls and 3G is off. The rest of the day, the phone is just on standby mode. I only have at most 10 widgets on the home screen. I have Avast Antivirus running in the background.
I am currently using Easy Battery Saver, Easy Task Killer, GO Task Manager and Battery Monitor Widget. I've uninstalled Juice Defender since I don't think it helps that much when it comes to the battery drain. Currently, the power saving option (available on Note) is enabled at 50%.

Any feedback or comment on this matter would be really much appreciated. Thanks!
From a personal standpoint. Your screenshots shows that your phone had never ever done a deep sleep at all. the 'Awake' mode is continously consistent as well. I guess the probable reason for that is you've installed ''Avast AV" on your phone. It's always running in the background (whenever the phone is ON). From my experiences, Any background application running would always cause wakelocks and the phone would never enter into deep sleep at all.
How bout you try uninstalling some of the background apps your using esp. Avast AV and give it a day to observe if your still having that battery drain issue. (Don't forget after uninstalling or removing those apps, try to wipe dalvik cache and battery stat and restart your phone after.)
and Oh by the way, I am using Juice Defender and contrary to your saying it doesn't help.. IT DOES HELP save battery as I my Note is able to reach 1.5- 2 days of normal use.
Cheers!
Yeah and download betterbatterystats and do some searching on it. With it you can discover what is causing those wakelocks. Search the web for more info on your wakelocks.

I'm using avast and never seen a drain like that. Only time I have is because of background processing. First thing I would do is turn off Background Data
Then as others have said - check batterystats to see where wakelocks are
Plus a rooted phone is a good thing. Titanium backup allowed me to freeze wi-fi sharing which also made a big difference
Finally - clear all caches from Applications menu and reboot

Only picture that shows that is the one with 1 minute 56 sec discharging time, so it was taken shortly after taking charger out. No suprise of it being almost 100% screen on time there if its only 2 minutes
Also installing "cpu spy" will give the cumulative time that your cpu spent at each frequency including deep sleep , mine is showing 88%
John.
Anti virus app is battery hog, I had avast before too, and I uninstalled it after 2 days using. Also that Juice defender, from my test before, it use up more battery than it saved. turning on and off those 3G/Wifi thing is using up alot of battery. and you know what? even the betterbatterystats use up alot, at least to me, becoz it scan what is up frequently.
Hello! Thank you all so much for your response. I've installed both BetterBatteryStats and CPU Spy and here are the results (please see attachments). Upon checking CPU Spy, it shows there that phone did went to deep sleep, maybe? I'm not quite sure, but it shows on the screenshot that it went to deep sleep for 19%. So does that mean the phone really went to sleep?? I'm sorry to ask this question, since I've never really encountered this problem before with my previous Samsung Wave phone, how will you know that your phone went straight to deep sleep mode?
Also, after 46 minutes or so, the battery went down to 96% already after charging it. The battery drain was already 4% in less than an hour.
@letters_to_cleo: I have not uninstalled Avast yet, since I'm still hesitant to use my phone without an AV. But I will try your suggestion for 1 day and see if there's any battery improvement.
I'm looking forward to your response or suggestions. Thanks again!
i am having problem too with new battery original samsung ( made in japan, finished in korea) previously i use samsung battery made in china, finished in korea. charged it over night with power off. it only last 13hrs. my wife phone can last 30hrs.
i've used batterymix to check the battery usage graph, the usage graph drop very fast compare to my wife phone. i'll post some screen capture of the graphs.
another issue is i used once wifi sharing. after turning switching the wifi sharing off, the wifi sharing service always at the background even after many reboot. how to turn that off??
You might need a new battery. Any rechargeable battery has a finite charging cycle. Just a suggestion.
Hi, all! I just noticed that the battery drains still even during deep sleep mode. After 3 hours or so (during sleep mode according to CPU Spy), the battery went down to 92%. It drains even faster when the phone is in use, especially when Wifi and Bluetooth are on, maybe 2-5% drain in 1 hour.
Maybe there's something wrong with the battery?? It's still a new battery and I can see some improvement each day though, but that's because I use it less each day. Before the battery can only last for 8-10 hours, then it increased to 12 hours, and then to 16-17 hours. BetterBatteryStats' current estimate to empty is 24 hours as of today, but that's because I only used the phone today for only a couple of hours, with 20 minutes Wifi and Bluetooth ON and most of the time, it's on deep sleep mode according to CPU Spy.
What do I do with the results from the Partial Wakelocks? Do I have to disable those apps?? The Kernel Wakelocks didn't show any reference apps running. The screenshots for the Partial and Kernel Wakelocks that were taken a few hours earlier still show the same results after 3 hours.

That would be really bad luck. I got my Note via preorder in Germany at the first day it was sold and since then I charged it everyday, sometimes even twice and there is no difference to the first day. If I get told by Samsung after 6month of normal usage the battery is dead that would be the last Samsung device I bought and I use a lot of Samsung stuff.
@ebichan24
Your last screenshots show between 9:35 and 13:35 5% of battery drain. That's not really a good value but ways lower than before. Did you delete some Apps or what did you change?
And since when occurred this issue? Did you install new Apps before this happened?
On my Note I had this issue sometimes without any changes but it was gone after a reboot.

Agreed with Kanalcommander.... try a reboot in the first instance.
Others have also noted that it takes a few refresh cycles before the phone more accurately reports battery use. Perhaps what you are reporting is because the phone and battery are new (new ROM or Kernel loaded?)
What I have done in the past is to reboot into CWM recovery then clear the battery stats (in the Advanced menu option) Recharge the battery to 100% until it says to remove charger and then use normally until battery down to around 20%, then recharge the battery to 100% again. Do this over a few days and that may help.
thanks, it is new battery two days old.

I was having similar problems with my new note and finishing full charge in 12 hrs but fixed some things and my last charge gave me 2d6hr seriously..few things i did were stop using live wallpapers! Get badass battery to thoroughly monitor stats and then use zdbox to extend life even much eg. I put phone to auto flymode using that app when its sleeping time rest i am more than satisfied even if on GB LC1 fw..waiting for official premium suite for ics since i recently upgraded from sgs2 using ics i miss that smoothness and much better bat life.. Let me know if can be helpful.. Good luck

That's what I'm currently doing right now, well, actually, what I do is I discharge the battery until it reaches 0% and turns the phone off. And then I charge the phone for 3 hours while it's switched off, I turn it back on again to check if the battery is fully charged and then I unplug it from the charger.
@Kanalcommander
**Did you delete some Apps or what did you change?
I haven't deleted any apps yet since I don't know which app/s to delete. Most of the apps I downloaded in Note were the same apps that I used in my iPhone4 and Samsung phone before.
**And since when occurred this issue?
This issue occurred since the first day I bought the phone, which was a couple of weeks ago. How long does it take to condition a new battery and new phone?? I'm sorry if I have to ask this question, it's just because I never really experienced this problem with my previous smartphones.
**Did you install new Apps before this happened? On my Note I had this issue sometimes without any changes but it was gone after a reboot.
I only installed recently CPU Spy and BetterBatteryStats and that's it. The drain of 5% from 9:35 to 13:35, the phone's just on deep sleep mode. And then from 13:35 to 23:44, it went from 92% to 74% while the phone is on deep sleep mode at 90% according to CPU Spy. That's 18% battery drain. It's just an unacceptable number for me. I tried rebooting the phone already, but every time I do so, just a few minutes after I turned the phone ON, there's already a 1% drain in the battery.
Also, does the battery really drain faster when the Wifi is ON? I've read in other threads that there might be some problem with the recent OS update that Samsung needs to address. Is this true?? Because as you can see on the screenshot below, the battery was still at 74% by 23:44 and then after I turned ON the Wifi and used it until 01:26, the battery went down to 54%. That's already a 20% battery drain in just less than 2 hours. I was only browsing through the Android Store and Skype.
Calibrate your battery in case you flashed any roms and for first usage I got my battery to 0% 3 times then everything is running great for example its at 47% now its 22 now and I have had it off charge since 7 morning..... i have wifi gps and 3g always on and use music player bluetooth and made some calls

My battery (also only a week old) drains quickly too. Can anyone tell me if widgets draw a lot of current? And then is it only the ones on the visible screen or do all widgets draw juice all the time?
I will ask such thing, did you guys check the battery expiration day ? Mostly sibce you got your phone almost a yeae after it was announced you nay get a bad battery, as for widgets the ones that are always active and asking for informatiom. Like location or weather over the internet yes they do eat your battery kinda fast.

Recurring battery drain? - Caused by memory of using app to drain battery?
Hello!
I used a battery drain app when charge left was 30% to accelerate drain to "die out" stage. After I completed the calibration process for unrooted phone as suggested in various sites (charge fully, switch off and charge etc.) I started using it from a 100% stage.
This afternoon when the battery showed 30% I saw in BMW the current flow was in -10ma to -15ma and it started spiking to hundreds. There was no change in settings or usage. From the 30% level it dropped to 10% in an hour and I had to charge again.
Was puzzled why the battery which was dropping around 0.5%/hour in standby earlier to the 30% level suddenly went down hill. My first guess was it was possible some file in the system remembered the previous usage history and replayed it out.
Any suggestions? Anyone faced this before? Everyone says LiOn batteries dont have memory so if anything it has to be the phone.
Thanks!
Hello I have a problem with my 4 month Nexus 7 3G. I noticed that recently the battery drains very fast in standby mode - for example 6-7% per hour. I installed better battery stats to see the deep sleep time and kernel/partial wakelocks... For example the tablet is 1hour and 20 mins in deep sleep and 1 min awake and has gone from 100 to 94 just in hour... Put the the tablet in Airplane mode, did hard reset, reflashed stock rom - no go... Is it possible that my battery has failed? And is it covered by warranty?

Read the first post in the BBS thread, do it. Post the log to their thread. Perhaps they can come up with something.
First thing I'd try is turning off wifi while it's asleep and see what happens. I've always turned off wifi while my tablets slept and I see about 1% every 6 or so hours, at most.
I factory reseted the tablet, switched the cellular off, the wifi off, turned off sync, didn't install or update any program... I put it in standby mode and after 57 mins it was 5% down. No kernel wakelocks, nothing at all, just deep sleep.
As with any form of problem isolation, you are going to try a few experiments to figure out where the problem is... and where it isn't.
If the problem is the battery itself, it will self-discharge even when the tablet is off and disconnected. (Not only that but the battery might be slightly warm when disconnected, but it might be hard to detect that without an IR Camera).
One experiment to eliminate this possibility is to charge the battery, turn the tablet off, and disconnect the battery overnight. Reconnect the battery, boot the tab, and then examine
the change in battery VOLTAGE, NOT "percent charge" *
You can use something like the app "Current Widget" to read the before/after voltage.
Note that you can't just turn the tablet off in this experiment without disconnecting the battery connector, as there is a possibility the the motherboard has a defect that drains power even when the tablet is off; although if you run this first experiment and find no drop in (unplugged) battery voltage, then doing this ("does the battery voltage fall a lot with the device turned off?") is a useful 2nd experiment.
*The TI BQ72451 battery charge controller IC attempts to gauge battery state by measuring both voltage and cumulative charging/discharging currents (by measuring voltage across a small resistor in the battery terminal path). This means that it is stateful (it has onboard flash memory) and more importantly that the "% charge" value this circuit produces is a computed value, not a measured value. If you are experiencing battery problems, the % charge value should be regarded with some amount of suspicion. For a healthy battery with about a 0.6-0.7v range (say 3.5v-4.2v), a 10% drop in battery capacity will be roughly a drop of about 0.06 volts.
This isn't a solution - but a place to start to eliminate some possibilities.
good luck
PS what does
Code:
$ cat /sys/class/power_supply/battery/health
return? (Should say "Good")
My tablet does the exact same thing. My battery average is 20 hours with use.
Sent from my Nexus 7 using xda premium
It says the battery health is good. I tried everything - reflashed the factory image, even 4.2.1 image, reset to factory defaults, removed the sim, switched off the wifi/nfc/3g... it drains exactly 5%/h in standby and the battery grafic show straight line downwards...The betterbattery stats says the 99% of time the tablet spends deep sleep. I came to the following conclusions: a) the battery has failed, b) the chip (or component) reading the battery stats is faulty c) a hardware defect that drains battery...It's not software since there are no indications that any piece of software is draining the batt.
If you turn the tablet completely off, let it sit for a few hours, and then boot the tablet, does it also lose charge this way as well?
How about if you do the above experiment - but unplug the battery completely instead of simply turning the tab off?
Doubtful this will fix anything, but it will give you more info about where the problem lies.
Along this same line of thinking, I note you have said nothing about voltages. Imagine that the charge controller chip thought that the 100% charge state was a lower voltage than what it should be - this would show up as anomolously large discharge rates (%/hr) even if the current draw was nominal.
I think 100% should be around 4150-4200 mV, and 5% around 3500 mV. (You can use the "Current Widget" app to observe the voltage in a convenient way.)
good luck

Note that the charger chip may not report a "% charge" drop even if the battery is self-discharging with the device off, as no current is detected in the battery lead. Hopefully what you mean by "doesn't drain" is "voltage didn't fall".
Well, I guess you now know that the problem probably is not the battery (although you should still confirm that the almost-discharged voltage is down around 3.5v).
Doesn't solve your troubles though. That 5%/hr drain with the tablet sleeping should be closer to 5% in 12 hours, so your tablet is doing at least 10x worse than it should.
Warranty return to Asus at this point?
Will relock the bootloader and return it to the Asus authorized service in bulgaria.

It's most likely the baseband_xmm_power wakelock, it's a nasty one. It comes and goes when it likes. Google hasn't come out with a fix yet. Reverting to stock doesn't help it. the only fix is to run Franco kernel, he patched it.

My battery was being murdered. Eventually I traced it to having Beautiful Widgets on the lock screen. Removed that and battery life is fantastic again. Are others using widgets on the lockscreen?

Lately for some reason my phone's display screen seems to be using too much power. Normally my phone would reach at the lowest battery level of about 60% (for about an 8 hour use - using whatsapp, fb, internet browsing,e-mail,etc.). However lately I get to about 40% now. GSam indicates that most of the power is going to the display however my brightness isn't on automatic or past the halfway mark. Is there any way to return my phone's battery usage to how it was before?
(I am using the RGUI V3 ROM with Android 4.2.2 if it helps)

I recommend using Snapdragon batteryguru. It learns your usage over a number of days and adjusts your phone for best battery usage. It also gives you options on when to allow apps to refresh in the background.
Also if you are rooted try either Bulletproof kernel or ElementalX. Both great kernels. ElementalX however, gives you options to undervolt, overclock/ underclock your phone etc.
Short of turning the brightness right down you won't get much less battery usage from the screen.
Judging by your images though you seem to be getting good usage out of the phone, specially with 12 hours off battery and over 2 hours screen with between 40 and 50% left.
Try the above though and see if that makes a difference.
Thanks, I'll install a new kernel and see if it makes a difference and the Snapdragon battery app.
I just found it strange that before it wouldn't use too much and now it's using over 50% at times.
Just wanted to share that the battery life is very good on the X9. I am getting about 5.5 hours of screen-on-time.
I unplug the phone at 6am and at 11pm there is still 15% left with at least 5 hours of SOT.
That's excellent, I'm only getting around 3 hrs SOT myself.
Yes, I confirmed it. My X9 is in good battery life, normally I only need charging it once per day, even if I used it to browse web, some gaming.
Same here. SOT is consistently 5hrs+. This includes some gaming , alot of web browsing and some music.
Screen at 40% , 4g off , battery saving location setting and haptic feedback/ touch sounds disabled.
Everything else default.
Even if fast charging is only ver. 1.0 battery life is good enough to not need faster.
Very happy with this phone all around.
Slightly disappointed with the battery life. The standby power usage is not great compared to my other modern android phones. It is lightly debloated with all the power saving feature on except power save mode. Using power save mode only brings it to about the same level of my other phones without it on... Then, there is my Z3c.
~5hour screen on time is not great as well. Comparing similar screen size phones, it is pretty bad as I get about 6 on my Note4 (which is faster and pushing a higher resolution), and Zuk Z1 (CM13 with undervolt), which easily get 9-10+.
Edit: Some overnight numbers.
My main phone is an S6 and before going to bed was @ 43%. Checked phone 11 hours later = 38%. This is with wifi on and syncing 3 google accounts, 1 IM, NO SOCIAL MEDIA.
X9 @ 52%, with Wifi, sync off (no IMs/SM installed), no BT, no location, 2 SIM active (both get 5 full bars @ connection) = 41% checked at the same time. Doze is on and confirmed working. I've used with only 1 SIM before and it really doesn't change the numbers that much. I wouldn't be so harsh on the phone if it had quickcharge 2.0. But it only charges slowly @ ~5V 0.96A. There is something funky with the charging numbers, since it bumps up to ~1.1 amp after ~80%. It also doesn't trickle charge after 90% and only drop to trickle charge after hitting 100%. I am not sure about the battery longevity on this thing.
I had bought my x9 2days back battery drains very quickly.....disappointed any solution plz

Same with all phones... check all which apps are the most hungry.
If you suspect its an hardware issue, factory reset then uninstall/disable as many apps as you can, charge up and let it run and see if it last normally.
Usually it should be some apps eating up the battery.
Dears All
There is an app (3C Battery Monitor Widget) in which you can inspect your battery to see if it works in normal condition or not. It shows you amount of real amperage drained from cellphone battery in different situation.
As I tested mine (htc one x9) it drains maximum current when capturing photo or recording video, location(gps) is on and map apps like google map is live, switching between different applications which result to rise frequency of cpu up to maximum (1.95 or 2.2 ghz in different model).
If you enable power saver mode in setting, maximum frequency of cpu wil be limited to about 1.32 ghz and conserves more battery and limits drained battery current below 900mA otherwise in aforementioned cases drained current will be raised above 1000mA and it is obvious that (3000mA/hrs) battery will be empty during 3hrs. Anyway normal application such as web surfing (specially with WiFi instead of mobile network), listen to music, talk with phone and brightness of display below 50% will result to more than 5hrs SON.
If you need more battery SON, one way is limit CPU/GPU frequency and some more sophisticated setting (you should first unlock boot loader, then root and also install kernel application or change stock kernel with custom kernel which can support change of CPU parameters the former is easier and the latter I couldn't find until now anything)
Finally I would be happy to announce you that I could reached 8 hrs son with this technique on my HTC ONE X9.
Battery life is quite good on my device too. Although I have disabled touchboost.
To disable touchboost open build.prop and change
ro.mtk_perfservice_support
From 1 to 0. Root is needed though.
Also limited max. Freq to 1.7GHz
1.9GHz is just an unnecessary heat generator and battery drainer.
