Battery problem

I've updated to DOC & Kalpik's new v6 from 5.1.1, and charged 100% before I went to sleep. In the morning(6,5 hours) the battery was 79% with screen off, wifi on(never sleep).
Even if wifi was on, I don't think it's normal(3g should eat more), so I wiped the system. Now I'll put the applications back day by day, and let you, and other people know what eats the battery.
Okay, a bit of an update:
If in 6 hours battery dropped 20%, battery should drop 3% in 1 hour. I was letting phone alone for 1 hour, and battery dropped 4%!!!!
Completely new system, it's newly wiped v6. Spare parts says: running 30%, screen on: 30%. No app, that uses cpu too much.
Installed applications:
- Spare part, Swiftkey keyboard, Astro, Battery indicator, autokiller.
wifi on : never sleep. Stock adw.
Any idea what eats the battery? I just wiped the system from clockwork!!

Froyo, that's what.

Is it?
With Doc's rom it shouldn't be a problem. It's highly optimised to battery consumption. I remember having version 5f of that ROM, and battery life was excellent! I don't know what happened...

1% battery drain every 3 MINUTES
One more thing I have to add:
I have 1% battery drain every 3 MINUTES if I'm browsing stock browser. Now that's waaaaaay too much!
What I do wrong?? Or is it normal?!

Battery life
I managed 6 days straight hehe with old style phone use, no gaming, no serfing, just 5-10min call time avg per day, a bt headset connected 5hrs avg per day, screen brightnes set to auto. Just once connected over wifi to download 1-2 apps and 10mb files. Fully charged on Saturday around 1pm, empty battery today about 2pm. While idle the battery drops 1% every 6hrs.
Won't do it again though, cause this is not what the phone is made for , i realy missed it during this test

You will get 1% per 3 minutes of high cpu and screen use (browsing)
It ends up at about 100-0% in 5 hours
That is what I usually get out of my battery on all firmwares, watching video's last longer though, 6+ hours

i have the same problem...
last week when i was testing doc/kalpik's or 2.1 rom i got 3% out of 6hrs standby.
last night it drained 25% on sleep! (maybe sleep is disabled somehow? or a tweak that is preventing it from sleeping properly?)
anywho.. before all this happened i noticed that the phone started to lagg (not the normal pause or two.. you could not do anything without it lagging..) it started to drain the battery (1% every 1-2min, screen on but not doing anything).. it went back to normal when i disabled usb debugging mode.. (very strange)
maybe there is a fix to this?
cheers

[Q] Bad battery drain, new SGS, tried everything

hello,
i've had my SGS for a little over a week now. from day one i noticed battery drain but i thought it was normal for a new device. i flashed darky's 10.1 extreme on the second day i got it because it was very slow and had a lot of bloatware ( i wasnt very patient and i flashed at 95% or 96% battery), the drain was still there. i let it go through a few recharge discharge cycles and no improvement, so i used an app from the market called "batterycalibration" by marosige, no improvement and it the reading would drop to 99% or 98% after taking it off the charger.
i did a little digging and discovered i had the android os bug (was over 50% usage usually) so i used titanium to wipe software update and samsung account, and froze the first, didnt help by much
i then flashed darky's again at 100%, and now it still reads full charge after removing charger and android os bug i gone (reads 4% system and 4% os), but drain was still there. i emptied it to the point it couldnt turn on anymore then charged it from wall charger while turned off to 100% while i slept
i woke up and tested it by playing a game (Blastmonkeys) for like 20 mins and the battery went down to 90%, that was less than 2 hours ago, and now its at 87% and it was completely idle
notes:
my brightness is turned all the way down with no animations but display reads 54%, wifi is usually on when im home but battery stats show 6% wifi so i dont think its a big problem
also, the device was bought locked in france by someone else and im in egypt, so i dont know anything about warranty..
im sorry for the long post but i tried to be as detailed as possible...

hello,when i upgraded my sgs to 2.3.3 i also got battery drain and android os was consuming hell lot of cpu about 70%,..,.,then i flashed 2.3.4 jvp i didnt get any battery drain in that firmware then i upgraded it to 2.3.4 jvq this also donot have ny battery drain..,,.i recommend u to flash it and try it once

will try, but isnt darky only compatible with JVH? what happens if i change to JVQ?

see jvp and jvq are bug fixing firmwares and i didnt use any custom rom ,..,i have stock firmware which i just rooted and didnt use any mod or rom.,,.,.jvp and jvq are stable roms diffrence between the both is that in jvq browser is improved gallery improvement,.,..,etc

As far as I know, the percentage not being 100% after unplugging is normal. To prevent wear on the battery, the phone cuts the charger after reaching 100%, and restarts charging when it reaches ~95%.
I don't think a 3% drop in battery over 2 hours is uncommon. Wifi and data connection will pull a lot of power if on, even in standby.

Normal, this phone drains about 20% battery per hour of screen use, slightly less when watching video.
2-3% drain over 2 hours is also pretty normal if you have wifi/sync on.

I just got my SIM card replaced today. The one I had used before was about 12 years old. So whenever you-re having battery issues, make sure your SIM card is not the cause for it .

Battery Drains during Standby Mode

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%.
Wifi and Bluetooth: OFF when not used

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

@TempusFudgeIt
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!

[Q] pm8921_eoc is keeping my phone awake! Help!

Hi guys, I am using stock Rogers Moto X and just upgraded to Kitkat. While enjoying the improved response time on Kitkat, I noticed that the standby time(everything off except radio signal) on this phone consumed more juice than on Jellybean. When running on JB, it used to consume about 5% every 10 hours with wakeup time less than 3% showing on Wakeuplock. However, it now consumes about 5% for every 6-7 hours!!
Therefore, I downloaded Wakeuplock, GSam battery monitor, and Betterbattery stats to collect some info. Although their functionality are very much limited under Kitkat, they still can collect kernel wakelocks info except Wakeuplock. The results were collected after I charged my phone to 86% and turning off everything except radio. Time period was 7 hours and 15 mins. See my results on attachments.
You can see that on Betterbattery stats it shows everything was alright. Deep sleep time was 99.3% and awake time was 0.7%. Deep sleep time was very satisfactory. While on the Wakeuplock, it showed awake time was 26%! Although I think it did not reset the time to 0 after I unplug my charger so it probably not that accurate but should be at least 15% of awake time. It also cannot display anymore details under Kitkat. Last but not least, on GSam battery monitor, the result shows pm8921_eoc was keeping the phone awake for 1 hour and 4 min for the duration of 7 hours and 31 min which makes 14% of awake time alone. I have never seen pm8921_eoc this high on my kernel wakelocks. I did not download any new apps(except these wakelock apps) or change any setting to my apps after the Kitkat update so it shouldn't be my apps that causing it.
So what is pm8921_eoc exactly? And how should I reduce its waking up times?

Better battery life and performance!

Just wanting to see what mods/apps you all are using to get the best battery life and performance out of your s5 I'm currently using
Rom: DynamicKat 2.0
Greenify with boost on
DS battery saver custom profile
Lux auto brightness
I'm getting a benchmark of 37000
And I'll attatch a ss of my current battery, i normally go 5-6 hours before I'm below 20% but I'm over 4 now and still above 60%

How much screen on time are you getting? 4&1/2 hours on battery and already down to 64% doesn't seem very good. I'm getting much longer times than that. I'm on Stock Rom, rooted, running Greenify.

same here, i get pretty good life. on very low use day, about 2.2%/hour. on heavy usage about 3-4%/hour. 4%/hour = about 20 hours give or take (gotta figure that screen on time is going to make it less than the actual maximum %/hr)
some days im at about 40% when i get done with my day, others im at like 55%. but still its from about 9am to 12:30am, about 16 hours-ish.

before i bought my zerolemon 8500 battery. i tested stock battery and for every 1 of screen on time, that would be 25% of the battery on stock.is that good or bad?

I keep my screen on pretty much all day it's very rare that I go 30 minutes without it being on

Battery life
By the end of a work day, my battery is usually around 50-60%. On weekends I don't recharge it at all, including this last 3-day weekend. It was at 43% Monday night. I never turn it off, I check it often as I get a lot of email.
I am running Dynamic Kat, just upgraded to 3.0. I use no apps to extend battery life. I turn off my wifi when I go to bed, turn it back on when I get up. Note that I NEVER turn data on.
