[Q] My Stand-By time is about 10 Hours

If I were to leave my phone on without using it, it would die in about 10 hours. Is this normal? It's been like this since stock. I don't think this is normal since my G2 had way better stand-by time.
Please, don't say it has something to do with your settings and stuff, because I had the same things turned on with the same apps on my G2 with way better Stand-by time. GPS and Auto-backup.

Im running bone stock. I recharged after 38 hrs. And still had a 30% chg left
These were 14 hrs after complete chg.

See? This is what I'm not getting. Even since stock my Standby time was horrible. So I rooted to get better battery life. Nothing is changing. I even did a battery calibration to see if the phone was just reading the battery wrong.
I have another question. After the phone is finished charging at 100%, as soon as I take it off the charger, it goes down to 99%. Is that normal? I thought the phone was supposed to stay charged at 100% for a little while.

I just unplugged mine from complete charge and as soon as I unplugged it went to 99. So, yes????

That is normal to drop to 99% immediately. I always charge to full before I go to sleep at night and for some reason if I leave wifi on, the drain is really low when not in use...

Ok. I have no idea what is going on, but my phone just randomly rebooted, froze and then reset my home screen replacement launcher (as if I hit set to default), and now when I went to check on the battery usage and this is what I get:
Android OS is now at about 2% along with other things.
Display is at about 50%.
This is new. Android OS used to ALWAYS be higher then display. That didn't make since.
Now things are different. It seems the display is using the most energy. That is normal. I expect that.
I don't know, but it seems that everything is back to normal. I am using the phone, so I'm expecting this battery drain, but I'll check to see how much battery is drained on stand-by when I go to work later on today.

Let us know how it works out for you. Display should definitely be at the top if you are actually using the phone. At least it always is for me

If you want your phone to last you throughout the day, make sure that "Use Wireless Networks" in Settings -> Location is unchecked. That is the biggest battery guzzler this phone has next to 4G and Brightness. My battery loses 2% all night til I wake up (Thats 8 Hours!!)

I figured it was a Samsung thing. I leave GPS off if that's what you mean, but location services stay on. That's just a me thing.
///////////////////////////
Today after work, I lost 30% energy on standby. That's alright with me. It was about 6 hours of straight standby time. It seems to have gotten better. At times I'd lose at least half of my battery after at least 5 hours.
I don't know how the phone seemed to fix itself, but doing things doesn't just DRAIN the battery anymore. I was playing on the phone fixing my home screen launcher and my battery wasn't dying right in my face. I lost like 2% after having the screen on for about 20 minutes fixing up my settings compared to seeing 5+% in like 10 minutes.
I am satisfied.

Lol, your battery didn't fix itself, that sounds like somethings wrong with the battery cycle. Maybe you need to recalibrate it.
You see, sometimes if you overcharge a phone, especially when using a charger that isn't made for that specific phone (usually a charger thats too strong) it can throw of the charge cycle. Thus, it can take like 30 minutes to drop 50% and then another 3hrs for the other 50% (this is just an example). If you're rooted, I highly recommend doing a full battery calibration.
Secondly, the Use Wireless Networks thing in the location isn't really a samsung thing, i think of it more as a google thing. I noticed that when its on, Google is always sending information back to itself, thus keeping the phone awake longer. Thats why if you go to your graph, it show that your phone is awake more often then it should be. I personally uncheck it, because if i ever need it, I just quickly switch on the gps. Then turn it off when im done.Thats my recommendation to you. Yesterday, I personally got a full 24hr usage out of my battery, and it wasn't even all that light. I texted most of the day, made a few calls, browsed the web, and listened to music for a few hours on the subway. Pretty moderate usage.

See, I'm not exactly unhappy with my battery life... but seeing what other folks around here are getting MAKES me a little unhappy.
I mean, I went to bed at... I'll say around two AM last night at 90% battery. My audio book player ran for thirty minutes after that; woke up at about eleven AM, 53%. NOTHING CLOSE to what you folks are getting. All of the big culprits I've heard mentioned have been checked out, and I just calibrated, so I dunno where else to go with this.

Does anybody see anything unusual about my battery life?
My screen has basically been off, yet I'm still losing weird amounts of battery. Based on the hours, I took my phone off the charger at 4pm Dec. 04 (16:00) and it died at 6am (06:00) Dec. 05. That gap in WiFi was my time at work.
Those bars you see in display right before WiFi get's turned on is me texting and Facebooking. Apparently I wasn't using Facebook enough for it to actually get a place in my battery usage.
And of course those two little bars in the red was my phone telling me that it's dying. Too bad I was sleep.
Ignore the rise after the fall. That's it charging of course.
Also, if you notice, my WiFi apparently wasn't using anything to get a place as well. Those are all the apps that were listed. Why isn't WiFi there?
I calibrated my battery twice already. I can calibrated it again since it fully died. Let me make sure I understand how to calibrate it.
ROM: ACS Syndicated Ice
Kernel: LoS Kernel
1) Phone charged to 100%
2) Phone dies
3) Charge phone to 100%
4) CWM and wipe battery stats
That's what I do to calibrate it.

Add a 5th step which is using the battery calibration app from the market. Also, uncheck wireless networks from location settings (huge battery hog). I assume that's probably your biggest problem. Then, if you are rooted, do what I did, which is get a root explorer and go into system>apps, and move the social hub.apk and media hub.apk to a folder on your SD. It will essentially uninstall it. Those 2 apps are battery hogs as well even if you have never used them. They will always run in the background. Try those and lemme know if it helped.

Wireless network location settings is also mainly used by Google to send them data about your usage. I noticed a significant decrease in battery life whenever this is checked. I would rather just turn on my GPS whenever I need it than keep this function on at all times. Its just not worth it in my book.

4G Battery Drain

Hey, im on Telus so i dont have any other modes I can switch to to lower the drain. Ive noticed my battery drain is HORRENDOUS
Over the past 4 hours ive dropped 60%!
Now im wondering if im just running too many apps or if my stock battery may not be holding a proper charge anymore, and wanted to compare with others to see if others are running the same amount of apps and getting better battery or what
Ive got the following on:
Trillian (IM app)
K9-mail checking 2 aps
Regular Sync (Twitter, FB, Dropbox, Google(Calendar, Gmail, Contacts)
The battery usage summary seems to lie, 35% is the screen but only 13 minutes. Yet im at 40%
Android System at 20, Cell standby 13, Phone Idle 8
While heading to work, i ran DI Radio(music streaming), and lost 20% over around 35 minutes.
Im using the Tuesday rom with it's default kernel.
Is there anything I can do for better battery, because I dont have wifi in most places, and im running 3-4 bars constantly yet the phone just drains rentelessly. Even my Mugen battery was only lasting 16 hours...

It's quite possible that it's the ROM. I used to always get 8 hours on a single charge, regardless of location or ROM. I'm running Eugene's CM7 and I'm getting 13 hours on the same typical usage.
I'm running on Telus as well, with no wifi at all.
Although I am not running all of your apps, I would still consider myself a moderate to heavy user.

Its been a while since ive run juggernaut. But it used to only drain 10% an hour i believe on 4g. I've restored my nandroid of Jugg and will be monitoring that.

any syncing or usage of the network will take a drain. any usage.
you can always turn on airplane mode and let it sit a few hours and see the drain, that determines whether its network or a ROM/kernel drain.
But yes, using 4G has big battery cost

Battery Life
I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.

I'm at hour 8 today on Darkside Digital Warfare, and 70% free from 8am to 4:30pm. I have push corporate email, automatic brightness, friendcaster push, and a slew of accounts and it runs like a champ with amazing battery.

Make sure your phone is going into Deep Sleep as often as possible when screen is off. My phone seems to be extremely picky in regards to which charger it likes and more often than not (even had this happen on the stock charger) the phone refuses to sleep after being charged (even if only for a few seconds...).
Download CPUSpy from the market and after each charge, go to CPUSpy, press menu and Reset Totals (phone cannot enter Deep Sleep during charging so it's important you start fresh after a charge to get accurate sleep time). Turn the screen off for a minute or two and turn it back on. Press menu again and Refresh Totals. In my experience, if the phone is not sleeping at this point - Deep Sleep showing in Unused States - then it will not sleep all day and remain in 384Mhz for hours, killing the battery rather quickly. From then, if I plug the phone in a supported charger (even for a second) and disconnect, Deep Sleep resumes normally. Rebooting always fixes it too.
If, like me, a lot of people also have this problem with the stock charger as well, I bet many are dissatisfied with the battery performance... The phone is supposed to spend the majority of it's time in Deep Sleep. I get this issue with several different chargers and cables and on different ROMS / kernels (including stock... go figure).

Im pretty sure its the signal itself draining it. It uses sleep for at least 40% of the time its on. I use my phone a good amount, but its the fact that if it sits on 4g even with the screen of, its rapidly draining during this time. ive even reset timers and left it sitting for an hour and itll be in sleep but lose 8% over an hour just doing nothing. I still wanna be able to recieve notifications tho so turning off data isnt an option. I will test turning off data anyways to see if the drain stops.

The battery drain is all those persistent internet apps running. That is what you call heavy usage. Trillian and the FB app being the two biggest. Music streaming would be up there as well if you aren't in good signal area. Look at your battery stats and see what your signal strength is.

Battery Drain Problem

So I bought my ATT GS3 out in Los Angeles this summer and then I returned to New Jersey to find that I have horrible battery life. It was not right away so this could be completely unrelated. As of right now my phone is at 75% and I let it drain while i was sleeping for 10.5 hours. I have tried several different roms which are usually good the first two days and then after that the battery life is bad again. I thought it may be some application I have installed so I removed a few of the ones I remembered downloading since I got back to NJ. I also updated to the latest radio ending in H9 because I was two behind when I checked. I have attached some battery information below. Any help anyone could provide would be great. I have tried Juice Defender which did save some battery life but it also caused a problem where I couldn't use the internet for 10 seconds after I wake the phone.

U need a Rom with cell standby fix
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

I thought the cell standby problem only effected the international GS3? If the cell standby fix was the problem then I shouldn't actually be draining that low right? Something must be draining the battery then. Google maps is probably draining the battery but how do I stop that from happening?

No its not just international and it is cell standby using almost 10% battery

Ariel 2.10 fixes everything!

I just installed the standby fix and im going to test that and see if it helps. If that doesn't work I'll try the other roms everyone has suggested. Will take a little while to make sure whats good and whats not though. Thanks for the advice.

Just another observation. Battery tends to drain faster if you leave it in your pocket. If you flash a rom, you might have to calibrate the battery stats. I only lose 1% every 2 hours overnight if I leave it on a cold surface.
Sent from my SAMSUNG-SGH-I747 using xda premium

So I have tried a few different roms and I'm still not happy with the battery life. I calibrate the battery after every rom installed and I usually keep that rom for atleast 2 days to test it. Right now I'm on AOKP. If the phone is on standby whats the general %/hr? When I go to sleep my phone drops from 92%-75% for about 10-11 hours (on desk at temp 60F). By Apocalypse487's response I should only see a drop of 5-6 % over night when I see 17%. Am I supposed to me losing this much battery life over night? To me I feel like I barely use my phone. Today wasn't too bad with 1 hr with screen on and about 1 hr in calls. I made it about 1 day 1 hour 36min on battery. My phone was sleeping for about 23.5 hours. Is this the typical battery life or is something wrong with mine? Tonight I'm going to try juicedefender and see if that helps.

I'm using ParanoidAndroid based off of CM10. Version 2.16 of PA gave me the best battery life. Try that. Certain Roms have better battery management, but that probably depends on the kernel. PA uses stock.
Sent from my SAMSUNG-SGH-I747 using xda premium

I'll give ParanoidAndroid a try and see what that does. So Juicedefender ended up making it so I only lost 1% over 9 hours. Thats pretty good. Way better than I wanted. So what could be draining the power over night. Is it because my data is on all the time but shut off when using Juicedefender?

I use Trinue 2, and I use an app called Go Power Master.
In GPM you can setup options that will turn off mobile data/gps/wifi when the screen is turned off, will automatically turn them back on when the screen is back on.
Those things little things I find can make a big difference for the battery to last throughout the day.

It's as Sianspheric says, common things like gps, data, and wifi uses power. I just started using Juicedefender since my friend told me it helps. Also download battery calibration. It's a root only app. Don't let your device discharge completely. It's bad for Lithium Ion batteries. That will clear out any bad data from Samsung.

[Q] Short battery life

I've had my Galaxy W for just over a year. Whilst I was running the stock ROM I would more or less get a full day out of the battery. I upgraded rooted my device and installed the Cyanogen CM9 rc2 ROM. I don't recall any battery problems at first, but just over a week ago it started draining within five or six hours. This happened every day for a week.
Since then I have uninstaleld all apps (apart from Google Authenticator which I couldn't manage without), turned off wifi, bluetooth and everything else I could think of. Now I seem to be getting about 36 hours out of the battery... Although I think it goes from 35% down to 10% very, very quickly.
Leaving all data connections off and having no apps is okay in the short term, but is there a long term software solution?

Not immediately, but about a week later. Is it worth going through that process again?
Edit:
This is the app that I used:

Before I uninstalled any apps I downloaded and installed CPU Spy. Here are two screenshots taken with CPU spy.
I could reinstall it now without any other apps installed, if that will help?
I don't know enough about this, but I expected that the phone would spend a higher percentage of it's time in 'deep sleep' than that.

That should have been right. I don't know what is happening with your deep sleep, although your phone is on for 16 hrs but the deep sleep only reach not almost half of it. Did you use your phone often?

For battery problem is either the phone calibrated wrong readings on the battery or the battery it self is the problem.
If you use your phone not too often but the deep sleep only reach 34% of the time then some apps is preventing the deep sleep, try to check what apps is that causes that with some battery stats app, try search it in xda or market

I've gone for Battery Stats Plus. I'll reenable wifi, bluetooth and 3G for a few days and see what happens. If that takes a toll on the battery I will post back with details from Battery Stats Plus.
I will also take the battery out later to inspect it.
Update:
My battery had 15-20% remaining and I turned it off, and tried to turn it back on. It now thinks that it does not have enough power to boot the phone. I don't know if that new information is helpful or not.

With 15 - 20% it should have boot, because it still have juice left. What about your battery physics? Is it bloating or just normal?

;D

Took the battery out this morning for a proper look. There's definitely some bloating. Time to get looking for a replacement battery?
Could there be two issues here? As from the screenshots I posted the phone doesn't seem to have spent a lot of time in deep sleep.

I was just watching a YouTube video, with about 70% battery. The phone turned off, and when I've turned it back on it's gone down to 2%.
Could this be down to an improperly calibrated battery, or is it purely down to the physical damage/bloating to the battery?

most probably you suffer wrong calibrated battery problem , I think
sorry I didnt see your first post (about bloating) :/ , definetely you should buy a new battery

Thanks for your advice.
I'm going to install Battery Calibration by Nema from Google Play. I'll see how I get on with that.
I'm going to order a replacement battery this week. I'm looking for a direct replacement, with an official Samsung battery. I have posted here in the Accessories forum. I hope that was the right place to put it.

After I install the CM10 alpha 6 conform to the first post, the battery life of my cellphone has been drained very fast - 21% about 6 hours and half.
Can anyone help me, please? I already did the battery calibration and I can't see effects. I'm wondering if is better install CM 9 or just go back to the android 2.3.6 factory version of my cellphone.

Your battery is bloated? Then you *must* replace it. Period.
A damaged battery is the root cause of myriads of problems. Until that battery is replaced, you _will_ experience all kinds of annoyances, no matter what ROM/Kernel you're using, including inexplicable battery drain.

I dont get it.. I got the phone 3 days ago, but if Im lucky, the phone lasts for maybe 6-7 hours?
It gets extremely hot when used in couple of minutes, and its like the battery is drained by something hidden.
On a night it loses about 6-7% in 6-8 hours of standby with data etc turned off
I have turned push, sync, NFC, smart screen and all that "smart" stuff off.. so I have no idea bout what drains the battery. Even the screen is on 50% and auto -_-
I have the korean version (I think?) the european version - bought in Denmaek, stock. Not rooted or anything - but is it possible to root the EU/KR edition or is it only for the Canada/Sprint edition?

Same for me. Hes obviously not using hes phone much and not on LTE.
The battery life of G on LTE is really terrible.
By the way mo on arent hot last days, probably they fixed it.
Web via LTE eats like 15%-20% per hour, reading a book on small bright is 3%-4% per hour

Is there any way to tunr of LTE/4G then? I'd rather have good battery and like 20mbit than a few hours battery and 45-50mbit download speed .. :laugh:

Battery life is consistently around 11.5-13 hrs with moderate to heavy usage.

My battery is crap too sometimes is ok ..
but it is just screen what drains .. and + if u browsing internet and u have flash enabled it is big drainer added .. needs more cpu power..
if u put mobile on eco mode turn down screen to 25%-30% turn all radios off u should be fine
download apps like battery calibration . or battery stats or juice defender

I'm really not an expert at this. I have also just opened my Optimus G, so I can't share my personal experience with this phone. However, the battery of my Lumia 920 needed around a week to function properly. The first three days I got heating and drain, almost 10% per hour, but now the phone lasts easily for two days with light usage. I was looking everywhere on different forums for hidden factors draining the battery, until I found a comment, where someone described this phenomenon: he said that a battery needs around 12 full cycles of drain and full recharge before optimal performance can be obtained. So from now on I will be more patient.
Then again, I'm new here, so other opinions are welcome.

eeemm that is not true i had phones over years and batt been always same..
it is all about usage ..
jut do test charge it fully and dont do nothing with it just ocasional phone calls and sms's and ull see then..

For me on jb v03 I get around 18-19 hours with around 3 hours screen time, but agree its all about usage.
I mean if you leave your phone off most of the day with your wifi and data turned off it will drain very slowly..
I find the biggest drain is always screen, cellular connection especially when you have poor signal, and wakelocks.

I had same xperience with my iPhone 5 so I hope its the same with my LG.
But for know I've installed JuiceDefender and disabled LTE (HSDAP+ i fast enough for my needs on the phone anyway)

exactly this is my problem ..
we traveling to the places while am in work and there are areas where is poor signal or no signal that means phone automaticaly boost its signal which is very big drain and if your mobile has no signal at all and u obviously set to automatic search it searching searching and draining hell lot!

this is true as well 4g signal is even stronger signal as previous 2g 3g drains so much plus when u surfing on the net!
when 4g will be standard the manufs will have to make new generation of batteries to stay last longer o LTE..

Phone idle is draining battery for me. Any suggestions?

I've already installed most of "LG" apps that were preinstalled on the phone.
Phone idle 28%
Screen 17%
Cell standby 17%

Phone idle refers to the amount of battery cell radios are using up when the phone is sleeping. I would recommend moving to an area with better reception and disabling data when unneeded.

Data is disabled (and wifi).

battery life is fantastic, i get roughly 5 hours on screen time, when i finish work i have 70 - 80% battery with 1.5 hours screen time

My battery life on CM.
Disappointed kinda, expected great improvement compared to stock rom

After few weeks of heavy usage, I am noticing the battery performance to improve considerably, I'm running stock 4.1.2. V10D
