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.
Sent from my GT-N7100
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.
Sent from my GT-N7100
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.

It looks like you were had screen on for close to 2 hours and made a phone call, albeit short. This is normal battery life for as much as you use the device.
You should try manually sync or set the syncing interval as high as possible.
Wifi always ON doesn't affect the battery life unless your wireless connection is weak/unstable.
Lower your screen's brightness or use Auto Brightness.
Fully charge your phone and let it alone for 2, 3 hours and check how much battery drains. If it drains 3-4% in idle mode, it's normal. Check also if your phone wakes up a lot, maybe some apps are running in the background and they wake your phone up frequently.
Hope it helps.
I used to have really poor battery life and like you wondered how people managed to get the stats I was seeing here.
I recently decided to do a factory reset for a different reason and to my surprise my battery life has improved incredibly. Yesterday I got over 18 hours in total with over 4 hours on screen time. This was with the stock gsm battery. Granted I was using wifi throughout but I was lucky to get 8 hours before the reset, even with wifi. With 3g I'm now getting 14 hours easily with over 3 hours screen time.
My point is if you've never done a factory reset, you may want to give it a go.

It's a bit hard to diagnose the problem based on only a screenshot of your battery stats.
Since your screen is using over 50% of your battery life, my guess is that you just had your screen on for about two hours of the total two hours and forty-five minutes. It's normal to not get more than about two hours of screen time. (Tap on the Screen part of battery stats to get more info on how long the screen was on for.)
In my experience with three Android phones (MyTouch 3G, MyTouch 4G, Galaxy Nexus), all the usual tips to conserve battery life pretty much do nothing to improve battery life: turning off syncing and background data, turning off wireless, don't use widgets, turn off GPS, etc.
Pretty much there are two big battery suckers on Android phones and particularly the Galaxy Nexus--the screen being on and LTE being on. If you dim the screen or just keep it off, you will seriously prolong the battery life. And if you use CDMA only, you will also seriously prolong your phone's battery life.
That said, it's also possible something is wrong with your phone... or your battery. We can't know just from the screenshot you posted.
This looks normal. How much screen on time do you have?

These kids these days...
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.

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.

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.

Thanks. I'm with us cellular and the phone is only two months old. They do have a battery swap benefit, but I think it can a crap shoot on the quality you get back.
I un installed that hacked s-voice app, that seemed to help quite a bit.
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 also have extremely high drain while on wifi, I just made it so the wifi shuts off when the screen shuts off
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?
Sent from my GT-N7100 using xda premium
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.

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.

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?

Running 4.2.2 I get 9h of standby and 1h screen on at the most on a HSPA+ Galaxy Nexus using a OEM 2000mAh extended battery.
I checked wakelocks and there was nothing out of the ordinary. Anyone else getting this bad battery life?
A phone that dies half through the day with light usage is pretty much useless. (I've had to use the 1750, 2000 and the 3800 battery to come through the day.)
Depends if you have any apps syncing a lot or using the radios a lot.
Signal strength plays a big role in battery life as well.

I just started using a Nexus this week. I came from a RAZR M. The first thing I noticed was the lack of battery life. I found a couple tweaks to help with this issue.
They are: disable network time and date sync, 3g only till you really need to charge through some web browsing, undervolt to 1GHz, and minimal to 383 or so. I flashed the Franco kernel and use the Wheatley governor. Auto brightness was on auto. I also have the 2100mah battery.
I can almost reach 3 hours screen time per charge. I didn't realize that's a feat so I haven't taken a screenshot. My M got around 5 hours screen time. Ugh.. But the Gnex has won me over.

And if you undervolt too much it will actually destroy your battery life

My device is deep sleeping fine, it is really a 3G/data issue. On wifi I can get 4h screen on and days of standby, no problem. But on mobile data my battery just evaporates in thin air.
I think the real problem is the 3G radio power management, that was excellent on 4.0 or 4.1 (never had issues) but on 4.2 it is outrageous.
The thing is, on wifi (home/work/...) I have the possibility to charge my phone. If I'm on HSPA+, I haven't.
My stats on wifi at the moment: 2h standby, 35min screen on 89% left.
Select 2G only if you do not really need 3G or LTE for phone and data! For simple phone calls or texting, the quality is not much different between 2G, 3G or LTE. In fact, in my city, there is more 2G than 3G and LTE transmissions.
It will at lease save you 30% battery.
I can put my phone on 2G only, but than I can't search something when I'm on a call, get delayed sms (really noticable). Not mentioning 2G is a pain in the ass, even for IM and email.
And constantly switching between 2G and 3G is also not a good option for battery life. Turning LTE off on a maguro won't do anything.
It doesn't matter how many features you turn off, battery life will not improve. Your phone will become a dumbphone and it will still die on you. I recommend to stop turning on the screen constantly and use it lightly. The screen used on this device is not efficient at all. I hope the next Nexus greatly improves on battery life or I'm switching to something else.

Android OS is high, BBS will tell you what it is, it's usually a kernel wakelock. Also if you don't use Maps, disable it, because since they brought the offline prefetching, it starts services like mad and runs in BG. Android AOSP has it's own location services and MapView, so you won't loose that.
My phone has become almost unusable after receiving the 4.2.2 update (on Verizon, totally stock phone). Battery has gotten as hot as 113F at times, and I can watch it decrease 1% at a time very quickly...
BBS keeps pointing to Exchange. I removed the account the first day and added it back in and that seemed to have helped initially but now is no longer the case. I haven't wiped the phone in over a year plus so this is my next step.
Is there any way to see what apps were recently updated?
Same battery problems for me (maguro). Not long ago I could use the phone for around 48 hours without charging, and suddenly one day to another it all changed and is drained within 9 - 10 hours. I have tried everything:
- monitoring with betterbatterystats (nothing out of the ordinary),
- tried different roms (including stock 4.0, 4.1),
- tried monitoring with betterbatterystats without any apps installed (disbled google apps to prevent syncing), without wifi / 3g / location services / NFC etcetera, even without sim card. --> No big battery draining wakelocks.
- tried different kernels
- tried new battery
- checked if phone was going into deep sleep (did that fine)
All without any impact, the battery life is still very bad (easily draining 5+ % per hour, if it is on standby all the time).
I'm starting to think it might be a hardware problem, I don't know what to do anymore without sending it back for warranty.
3 initial things I always look for when diagnosing somebody's battery woes:
1) Have you loaded (adb then fastboot) the totally stock nexus images from Google's website? At least for 3 days and no additional apps installed
2) How old and what is the usage of your OEM battery? If you're using a 3rd party battery who knows what will happen
3) What's your signal strength like in your daily travels? Bad signal will eat your battery almost as much as screen time
If you still have bad battery after thinking about those 3 questions then you have a unique situation. Otherwise, your problem might be simpler than it seems
IMO, turning off gps/wifi etc doesn't really help with battery life, at most 1-2%. Usually what causes battery to drain faster is when apps prevent the phone from sleeping, or if they're constantly running in the background.
