I hate to be the guy that asks this, but I just want to make sure as from what I understand this is different from phone to phone. From what I understand, Li-Ion batteries, like the GN2's, do not have a memory effect of any kind? And thus all battery calibration rituals and nonsense are entirely pointless for this handset?
The reason I ask is because I wasn't able to charge the device to 100% before use like I was always told to do with new phones. My device was turned on and used until it drained to around 10% at which point it was charged to 100%.
Now, after 2 weeks of use, I feel that my battery is not as good as it should be. I'm barely able to get more that 12 hours. I'd be happy to post some battery graphs in the morning.
One last thing, if I did mess up my battery, or if my battery is messed up or less functional than it should be, would buying a new battery fix all my problems?
Youvare right. All that calibration stuff is nonsense.
I have never charged my phone to full before using and draining the battery and my phone still lasts all day on mostly heavy use.
Could you post your batt stats?

Today I ran my phone with the "lowest" possible settings, that is lowest brightness, CPU power saving, and no haptic feedback. I did not turn off wifi. Doing this I was able to get a surprising 16 hours, although you can see from the graph that I didn't use my phone as much. Attached I have a screenshot of what it's like with the highest possible settings (no power saving stuff, and brightness all the way up, but no GPS). Sorry I don't have a pic of the percentages for the high settings, I never thought to do that.
What concerns me the most is this: even with the lowest settings, I'm only getting 2 hours screen time. (last pic)
What's interesting is that you would think that if I'm getting such poor screen time, there would be something else using a lot of battery, but there isn't. This led me to believe the problem was with the battery. I discovered a pretty big scratch on my screen the other day, and I have some monthly insurance plan from best buy, so I was thinking of just getting a new one. The longer I wait to get a new one, the harder it will be to set up everything again. lol
I noticed that compared to other GN2s, mine seems to wake up a lot when the screen isn't on. The awake periods tend to correspond with drops in battery and also when I have a poor signal. Could this be caused by my phone trying to look for signal and using battery?
Yes poor signal that results in the phone searching for better 3g/2g will drain the batteey faster.
Can you try using it in airplane mode with wifi only for a day and see how that goes?
Also install Better Battery Stats and after a day or so of normal usage check your partial unlocks to see if a rogue app is preventing deep sleep and sucking your juice.

Yeah it us definitely your signal playing a role. Also you have a lot of wakelocks showing up
Sent from my GT-N7100 using xda premium
Dude you have major wakelocks that eat up 80 % of your battery!
Go to application manager and remove all the apps you don't use.
K, I agree with my week signal using battery. I only have 75 apps on my phone and they're all pretty mainstream, no obscure apps. Right now im in school with 86% battery, I'm turning on airplane mode now. I have noticed however that when I clear my ram it closes like 50-60 processes each time. I am always closing my apps, but 50 seems extremely high. im gonna turn on airplane mode and see how that goes...
thanks!
Yes, you do have poor signal but that's not all. You have terrible wakelocks pal. Install BBS and monitor which apps are the culprit. It's not about 75 apps, even 2 or 3 bad apps, which have hidden advertisement going on could suck your battery flat in no time.
So first thing, install BBS. 2h screen on time is horrible!
Btw- If you're on 3G, try to switch to 2G. Difference will be unthinkable.
Sent from my GT-N7100
Thanks everyone! I'm really loaded with school work, so I don't have a lot of time right now. But long story short, airplane mode saves my battery like crazy. I started school with 86%, turned on airplane mode, and I'm at 79% right now! more later
Is it safe to say I fixed it?
3h screen over 2 days isnt bad right? Perhaps just a bit worse than what others are getting?

Stop using the light and orientation sensors. So turn off auto-rotate and don't use auto-screen brightness. Also use wifi when possible; 3g will consume more power if your signal is weak.

It is not good for me either. I am loosing about 15% a hour with the screen off and not even using it. If I use the phone i can just watch it fall about 1% every 5 min. I don't get it. the only thing i have in the background running is weather, twitter and gmail. That is it nothing else. The Android OS sits about 86% use in the batter use screen. I have no idea what is causing this. Any help would be great.

Yes it is always posted that high. I have also already tried the suggestion of completely draining the battery and charging to 100% twice now. Doesn't seem to help. This is not my first android phone so I have tried all the typical turn stuff off. I started with the hero and then went to the evo. Then jumped to verizon for thunderbold and now back on sprint for this phone obviously. So far this is the worst battery life I have had yet. Seeing what you guys are getting though gives me hope.
I have tried using spareparts to get more battery information but get a force close when trying to do that.
Man I know that battery results range pretty wildly, but I'm averaging 10% loss per 2 hours.
On launch day I was on it from about 3:30pm until about 10pm and only lost about 40%. And when I say on it, I bet the screen on time was 95% of that time.
So far, the battery life is one of my favorite things about this phone. First time I've felt comfortable enough to run a live wallpaper.

You are lucky then, If i use the phone I will loose 40% in about 2 hours no problem. Also if you are loosing about 5% an hour that will only give you about 20 hours total before your dead. I see people reporting they are getting over a day. Just don't see how. Are they just not using their phone at all.

You SHOULD always when you get a new battery fully Drain it and then fully charge the battery with the device OFF. Thats what I did with my phone. I kept using it once I got it, it lasted around 5 hours before the phone shut off during a phone call. then when I plugged it in to charge, I plugged it in and did not turn it on and waited till it fully charged with the Blue Light. I dont know about the normal thing now adays with lithium ion batteries but you were always warned in the packaging to let your battery fully cyle its first cycle with no use at all. The cells in the batteries have a memory type of design and if you dont fully charge the battery you can prevent it from knowing its full capacity.
Now I dont know if this is true anymore with the new battery production of the manufacturers now may power cycle the batteries before they seal the whole package so the customers dont have to do it. Maybe why when you get your device the battery is around 50% now like mine came. I remember older devices you could not use your device until you fully charged the battery the first time.
About Screen Brightness, I learned from a Epic user that the best way to conserve battry usage was to always keep your Screen Brightness at 10% (Gotta love the Touchwiz Brightness Changing with the Top Notification bar, this device will not show the slider bar like Touchwiz 3.0 on the Epic but IT STILL WORKS!!!!). I have noticed that at the lowest brightness setting I can still see everything vividly enough to work with it and im getting over 24 hours with moderate normal usage (like only 1-3 5-10 minute phone calls, surfing the net, surfing for new apps) This is my first android phone. I also have had 4G turned off and Wifi off all this time as I have no way to access those right now. I also have GPS turned off because I havent needed to use it yet. I pretty much have everything but Basic needs turned on besides all the Factory default presets. I also Turned my screen mode to DYNAMIC, which seems to show more vivid colors like I use on my Samsung TV for my computer usage.
Now I turned off Live wallpaper and im using one of the preinstall basic Grey ones (the one with the asfault looking spot light) (I have been trying to hit the crazy benchmarks people are getting trying to find out why I am not getting the 93+mflops mine keeps hitting 80's) So I dont know what heavy usage is doing to my phone.
but then again this is only under 48 hours of ownage. My first full night off the charger was 1 day and 3hours before it said I was 5% battery life and I plugged it in.
Mine has been terrible for awhile. Even Odin back to stock and it wasn't any better. Now I'm on a clean flash with very little installed and I've only seen minimal improvement.
Here are a couple of screenshots from this morning looking at while I was sleeping. Lost 25% overnight. Had an hour of awake time with near zero screen time, seems like a lot of battery lost
You're letting way too many apps sync in the background, your phone is not reaching deep sleep. I bet you left your Google account on auto sync. Your email is syncing too often. don't leave wifi on overnight. You're getting poor signal too.

I've always let my Google account sync and left wifi on at night. It just seems like the last month or so it's chewed up lots of battery. Heck with my old desire it'd only use 3-4% (with basically the same setup) overnight.
I had this problem and was able to fix it by repeatedly throwing my battery on the sidewalk. It helps to re-excite the electrons in the battery and improve battery life.
I am trolling, in all seriousness, lithium ion batteries significantly reduce in capacity over time. It is perfectly normal for the battery to last 25 to 50 percent less long just a year in. Pro-tip, you can find replacement stock batteries on Amazon for about $10, just make sure it is an OEM battery. If you are nice to the tech or store manager at your local sprint corporate store, sometimes they will give you a replacement battery for free.

So it must be something with wifi. Had wifi off all day yesterday at home and last night (just using 3g connection) and I only lost 2% overnight. On 16 hours with an hour of screen time and still at 79%. Not seeing the wake ups and wakelocks like I was before.

Sounds like you've got apps set to sync when on Wifi only then. To confirm, try leaving Wifi on but turning off background data. If your battery life improves, it's definitely an app. Then you just have to go through your apps and figure out which one it is.
Gmail can be set to push so you don't have to worry about it syncing unless necessary. But if you get a ton of emails, it's still going to hurt.
Also, I disagree with revamper, if you get poor signal you should leaving Wifi on as much as possible. Being connected to solid Wifi will drain less battery than your phone constantly polling towers for a better signal (given identical app behavior, which you don't have atm). I'd still turn Wifi off when moving about, as you won't be on a single, solid Wifi connection and you phone will be polling both towers and Wifi networks, resulting in increased battery drain. You also want to set Wifi Sleep Policy to not sleep when the phone screen is off (otherwise as soon as you turn off the screen Wifi is disabled and you're polling towers again). From what you've said, it sounds like this is already set though.
The best thing I've ever done for my battery life was flash Calkulin's ICS ROM. 4 days of standby or a full day of some really heavy use. Email is the only thing that syncs automatically (push). Other apps like Facebook aren't that important to me so they only sync when I open them.

I had a battery cook in the phone this weekend and this is what the sprint tech did. I picked up my phone after being on the charger overnight and it was almost hot enough to burn me. I took it in, they popped it out and spun it like a top... Handed me a new battery within 5 minutes.
Yeah it's probably wifi. I also have much higher idle drain on wifi than 3G right now, although I haven't had time diagnose it. Actually, I hadn't bothered because I was planning to move to an AOSP ROM from stock ICS once kernel source was published, but I'm losing my patience. The AOSP guys seem to have things worked out without source anyways.

I've read a lot of posts complaining about battery life, and other posts about users suggesting ways to improve battery life. I've read stuff like, disable LED, haptic feedback, lower volume, lower brightness, LTE turned off, underclocking, turning off sync, live wallpapers, etc, etc. To me a lot of people are crippling their phones. If your battery can last you 10 hours, that's enough because you'll probably be somewhere you can plug in. What's the point of being able to go for 20 hours when you'll probably have the opportunity to charge it before then? It's better to have and enjoy all the features.
Maybe somebody can chime in and give me their point of view.

Part of the issue is a sociological thinking pattern between wanting "more" and needing it. Depending upon the type of lifestyle you live, sometimes, battery life is of dire importance to have if you're constantly migrating around. But I agree, some people who aren't in that sort of disposition go overboard with it.
I just bought a bigger battery :good:
I agree wholeheartedly. If your battery is lasting you through your day (which mine does, and more) then why try to conserve it?
Yea its funny stuff people complain their battery only lasts 20 hrs but yet they want it to be able to do everything a computer can do and more....
Sent from my SGH-I747M using xda premium
The only conscious effort i made to extend my battery life was to undervolt the CPU a bit, but this was more for the lower temperature advantages with extra battery life being an added bonus. Beyond that i turned off things i dont use like BT, no need having something running that i have no use for. Overall i was happy with the stock battery except for any kind of heavy video or game usage which drains it pretty quick - solution : bigger F'n battery :highfive:
i agree that some people seem a bit obsessive about it. but we shouldn give bad battery life a pass either. hopefully we will see some sort of advancement in batteries to have better battery life while keeping them at a decent size.
i was kinda worried id have horrible battery life with the S3 being that its LTE. my last LTE phone was so bad it would die after 8 hours idle.

How heavy is it? Does it fit in a case?
For me, and I want as much battery life as possible to avoid those situations where there is no way to charge you phone even if that only happens 1 a month or less.. As a parent I can't just let my phone die on me... I always need enough to be able to take or make that important calls/text. My goal is to have at least 20-30 hours of battery life per charge.
I think the only major feature I've given up is live wall paper. Other then that, it is just disabling other unused apps like gtalk, talkback, Google bookmarked sync. As well I've uv my phone as much as I can and run a 1350 max clock speed. I really don't see any major dip in performance as long as you do it right . I do use Tasker to disable syncing globally when the screen is off and make sure it automatically disable bluetooth after 10 mins once it disconnect. Also I have the Y5 app to automatically toggle wifi based off my network location. The most useful battery saver I've found is to set my wifi to only connect when the screen is on. Seems kind of backwards but it works well when very little data is process during idle rather the the phone requiring to keep a constant connection to wifi.

I work in an office so it's plugged in for the 2 hours before I leave so I have everything on full most of the day (brightness, lte...). Also, by undervolting I'm getting 30% more battery.

Its not possible. Not by solely UVing. The sole purpose of undervolting is so that your phone dosent overheat when running high clock speeds. Saving battery is just a perk. You might save a few percent with the undervolt but nowhere around 30%. But don't take my word for it.....

Alright first of all, i want start off by saying that i LOVE this phone, both in terms of hardware and software, however, theres is a HUGE problem that i just can't get through and its the battery of this phone...
It is simply unbearable.
I have posted the screenshots. This screenshot is taken after 1 whole night of charging. In 5 hours or so time, I've use the music app for about 1 hour, talked on the phone for about 5-10min and sent about 10 text messages. I didn't do any web browsing/videos/gaming. I have also disabled LTE and turned my brightness to minimum with eco mode on. These small things drained my battery from 100% to less than 10% within 5 hours which i find to be completely unacceptable.
Last night, with me browsing the web on the bus for about an hour or so, it drained my battery from 85% to 3% by the time i got home...
I've looked at the battery life thread and it seems like im the only one experiencing this issue. Also not only does it drain SUPER fast, it takes a good 4 to 5 hours to recharge this thing. Which means it takes longer to charge than to use up even with minimal use...
Do I have a faulty phone and should I get it replaced???
Something's amiss. The only time that I've gotten less than 10 hours, is when I had my work email connection set up to "always connected" and wifi was turned on. Even then, I got 9+ hours of battery life.
Disabling lte is part of the problem. When the phone is in 3g, it uses fast dormancy which LG did not implement very well and it runs the CPU constantly. I encourage you to contact LG and your carrier and complain. don't let them tell you about background data or applications running the battery down. With the same apps running, this does not happen on lte. This can easily be verified by enabling debugging and then capturing a logcat from adb with lte both enabled and disabled. It will show fast dormancy trying to set network states every second. I spent a lot of time trying to get this issue recognized, but they kept saying that it had not been reported and was not a known issue. Let's make it a known issue so they will fix it.
How about actually showing us what you used instead of screen shots of %.... would be helpful...

Well, a little update to this thread, i've disabled every different kind of syncing possible and i've been able to pretty much double my battery life from before, which is a lot better but i still wouldn't consider this to be good battery life.
I've been reading many posts regarding battery life, and it seems like there is some issue within the software that prevents the phone from going into deep sleep which is causing the lack luster battery life. This issue is on both the optimus g and the nexus 4, so i hope the devs may look into this issue when they are building custom roms for these two devices!

You definitely seem to have some weird issue's. My Optimus is great for battery life. My previous phone was an Xperia Arc and this has significantly better battery life without even running it in "eco mode". The only time I have noticed less then stellar battery life was when I had some app's running in the back ground that would keep refreshing/updating which kill's the battery.
Androids usage readings are inaccurate. Please consult this: http://forum.xda-developers.com/showthread.php?t=1179809
From what the picture shows I would guess its your 4G connection. A Hardware fault is improbable. And forget these things like "eco mode". Even if they underclock your cpu it won't give you a real benefit,
I've had great battery life on mine. Even when I've been geeking out on the device for several hours during the day.
Perhaps you are on the cusp of LTE coverage? If so, then the radio can kill your battery while looking for a signal.

With very very heavy use I can go from 8 am till around 11 PM. I am very happy with the battery life overall. I'm running on "eco mode" FWIW.
Hello guys.
I've been reading these forums for a few months now and find it very very helpful in configuring my device. It's just now that i decided to sign up so i can be part of this great community.
This is my first ever post and i would like to get help regarding my battery life.
Ive read a few articles about battery saving and also from forums where people usually get more than a day's worth of battery life. That got me wondering why i only get around 8-10 hours average considering i only use it very lightly as im usually busy at the office. My actual usage time range about 60% of those 10 hours when i use the phone during breaks.
Here are example screenshots of my daily usage:
Here are some details about my configuration:
Brightness set to auto, most of the time at 75% level
Wifi, bluetooth, gps always off
Haptic feedback set to minimum
Mobile data always on and set to WCDMA only, area where im at is usually weak peaking at 2 bars of H and H+ signal strength
Gmail set to push notify
A few apps and widgets set to sync after every few hours(accuweather, flipboard)
Ive been considering getting an extra battery because of this but i really want to make sure first whether i could still do something or whether im doin something wrong thateads to the battery draining too fast.
So please if you have any more tips i could use, please help me out on this.
I thank you in advance.

Their battery lasts whole day long. It means that they get 10 hours of screen on time only. Not 24 hours.

Yeah. But in my case the 10 hours is the total life of the battery from the time it is charged until it dies. I'd be lucky if i even get 4 hours screen time out of it.
Do you have an idea why this is so?
Im guessing its because of the weak signal where im at and the fact that i set my phone to search for WCDMA only. Although im not sure whether this is really the culprit. I'll try setting the network mode to auto for now and see if anything changes.

Looks like it.
Try better battery status.

Well after i changed it to auto it improved a bit. Its currently at 14% after 11 1/2 hours with 4 1/2 hours of screen on time. The phone stayed on full edge signal for most of the time (which kind of sucks because internet became painfully slow on edge).
But still, i think this is far too short when compared to those who can get it to more than 24 hours battery and more than 10 hours of screen on time.
Is it possible that i have a defective battery?

Do you have locations services and etc (all 3 options) checked in the maps settings?
I don't get near as good battery life and my phone spends a lot of time awake. This appears to be do to google maps constantly updating my location. I would turn this off, but then i would loose google now functions.
Any help would be great.

I have only two of them checked(Use Wireless Networks and Location and Google Search). I have GPS disabled. i only turn GPS on when i'm traveling to an unfamiliar place which is not too often.
i got exactly the same problem, whats your firmware?
since i updated the phone to 4.1.2 the battery drains alone, every 8 hours it discharges 25% without using the phone, i am lucky if i get 5 hours of screen. The android os is the one draining all the battery in my phone. On 4.1.1 i could get 7 hours of screen time with 20+hours overall.

i got 4.1.2.
I can't compare mine to 4.1.1 because when i bought mine it got updated to 4.1.2 after a few hours.
having to charge at least two times a day really negates the otherwise great features of this phone.
I really hope we figure this out. I'll try UtkarshGuptas suggestion using Better Battery Stats and let you know what i find out.
I did they and found Google location services is the culprit.
I'm am referring to the locations services found under location setting in the actual Google maps app. I believe turning of location reporting may disrupt Google now features. Google locations devices is reading out as the main reason for nine consistent partial wake locks on better battery stats.
I'll try turning these features off and awe how it affects battery life and Google now tomorrow.

Please let us know.
after doin some tests with bbs i found the wakelock is mhl_wakelock,
First off, forget all the battery programs. Factory default your phone and add an apk at a time and use. You'll be able to tell what apk is the problem with a lil testing. Slow process yes but pretty straight forward and to the point. I do have a Note 2 and have no battery issues being rooted and having tons of programs, etc. Basically, I use and abuse my device as per my job and still get a day and a half out of the battery.
People who can get 24hr coupled with 8hr screen time most likely have their phone on low brightness and on WIFI not data.
I got a new battery and its still lasts the same as the other. Yeah it may be because of the mobile data always on that eats up my battery.
Problem is my data connection is my primary internet source i dont always have wifi hotspots. So i might just have to live with the short battery life or learn to turn off my data when i dont need it.
I'll still try looking for other things that contribute to the battery being drained though.
Thanks everyone.

I have GPS disabled, auto brightness (but fairly high level) and that improved battery life quite a bit. I then changed kernel to NEAK kernel, reduced the voltage levels for the CPU and that further improved battery life. I can get a full 24 hours on one charge and with normal (?) usage). With the new kernel I can also modify the charging current to a slightly higher level which reduces the time to bring to a full charge.
All in all not too bad but to expect more than 24 hours is unrealistic in my opinion as it is a big handful of electronics!
Not sure what you guys are are doing different. This is my first full month with my note and the battery is a beast. GPS is enabled at all times but all other syncs are disabled. That's just from previous experience. Sync will always drain the battery. So mine is off. I went as far as removing all the extra chargers around my office and home. .now I only need one. And I alsi don't see a need for an extended battery unless I'm going to be away from civilization for a few days. By the way..that was the only time I've killed my battery..kinda. see screenies
--I forgot about brightness- mine is set to 50% and 4G/LTE ..if the device is always searching for it, it will kill your battery. I turn it off at the office as much as I can.

I get between 6-7 hours of on screen time on mine.
Using dark backgrounds really helped the bettery life for me. I use a dark wallpaper for touchwiz, whatsapp, and also carbon as my twitter client.
Using Perseus kernel also helped because it doesn't ramp up the cpu as high as the stock kernel.
Wanamlite rom.
Brightness set to lowest at home. 25-50% when outdoors.
Two MS exchange emails set to push.
I use wifi all the time unless it's not available I switch to HSPA+. what a waste of a paid data plan
Google now disabled because it's a battery hog. location services kept on though.
