[Q] How can I get good battery life without sacrificing too much? - Samsung Galaxy Nexus

I seem to get absolutely terrible battery life no matter what I do. Most of the time I'm lucky to get 8 hours.
It was that way stock/unrooted but it is no better with CM9 beta 1. Right now it is down to 69% after 2 hours with under 30 min screen on time.
I don't play games any more resource intense than Scramble With Friends and today I haven't played any at all. Most sync is turned off except Contacts and Gmail.
This is driving me insane... suggestions are much appreciated!

You have an app eating processes.
Install better battery stats from XDA to find what is keeping your phone awake.
Install Watchdog to find if any apps are running more than they should.
Worst comes to it, install everything one by one and find out which app or apps it is.

Just installed both of those. I will report back tonight.
Any settings I need to change in Better Battery Stats? I bought the paid version.

You didn't have to buy the paid version, it's free on XDA
There are no settings to change for better battery, just let it go. I haven't needed watchdog in a long time but you can set how aggressive it is if you'd like.

I appreciate that, but being able to install/reinstall from the store is convenient and I like supporting good developers.

Thanks!

No matter what I do, it is still terrible.
I know that I've heard that crappy reception can shorten battery life, maybe that's the problem. Where I live, the signal is very spotty and I'm sans WiFi for a week or so.
I'll post screenshots of battery/usage and watchdog, better battery stats when I get to work tonight to see if any of you experts can shed some light on this.

[Q] New Nexus Owner, and introducing myself

Hello Everyone,
Many times while searching the internet for Nexus information, the search keeps having me come to this forum so I decided to become a member. Just got for my G-Nexus the other day, its replacing a Droid 3. Nothing really wrong with the Droid (well), but it was my first physical keyboard phone and I wasn't feeling it, and I heard so many good things about the Nexus I knew I had to have one.
I've had it less then a week now, and so far I love it. Though the one thing I must say I am not crazy about, which seems to be a common complaint, is the battery. It drains WAY too fast. Today though seemed more then ridiculous. I left my house @ 8:45 am @ 100% (right off the charger). Made some use of it on the bus, but nothing much (no calls, no video, no music). Already by 11:30am, I was @ 39%! I mean come on, I didn't even use it that much. Yes, I did notice I left the WiFi on, but it should not have drained that fast. Tuesday I used the device moderately and I was able to go home after having the device on for 9 hours and still have around 40% to spare. Its a shame they cannot make a battery that can accommodate such a great phone.
So some questions: Is it really necessary for me to root this thing to get its full potential? I never rooted a phone before. When I bought the phone, I got a shiny gel case that Verizon sells for like $20 - if I did get the extended battery and door, would this case still fit? I am thinking no. Is the ext. battery even worth getting?
I have more questions, but I will peruse the forums and see what everyone else is saying. So in all I just wanted to intro myself and say I am happy to be part of the forum!
Your battery should definitely not be draining this fast. Install better battery stats(look around XDA) and look at what partial wakelocks you have. Try to remember any recent apps that might have been causing the drain
The 2100mah battery will fit. If you're looking at the 3900mah extended batteries, those have their own custom backplates and won't fit.
I've read that the 2100mah battery adds about an hour of juice.

Sorry to sound dumb, but what do you by "battery stats"..?
And I am not sure what a wakelock is either - if you could explain
Hey,
I got my Galaxy Nexus this week too. This is my third full day of using and I get good 10+ hrs of usage each day. I use it a lot too. At least 2-3 hrs of talking, about 50+ texts, synching 4 emails, and browsing/streaming an hour or two each day.
You should check what drains your battery the most and go from there.

'better battery stats' is an app. go look for it. there's an XDA version
your phone goes into 'deep sleep' to conserve power. wake locks are when something refuses to let it get to that state and locks it awake. This is major cause of battery drain.
Better battery stats is available on the Play Store (ugh hate that name) but the dev is nice enough to give it to xda members for free:
http://forum.xda-developers.com/showthread.php?t=1179809
Aside from looking at wakelocks, go to Settings>Battery, then look at the list of stuff (in descending order) that's eating your battery. I went to watch a movie once at 90%, when it was done the battery was at 18% and I never even touched my phone. I checked that list and apparently Facebook killed the battery. Try and look for apps that might be using up a lot and either uninstall them, replace them, or trun off features that might be causing the drain

Root it?
It's a Nexus man. They're fantastic for root users.
All the roms are AOSP...
And bug free (or...mostly. AS bug free as any google build, generally).

I agree with you that the Nexus is fantastic for root, but it's not necessary for all users. I rooted mine because I was use to with my old HTC HD2, but ,except for changing rom, it's useless when you just get your phone.
I think that you can keep the stock rom, and don't root it. One day you will maybe need it, but the stock rom is very nice, it's enough to start (that's what I did with mine).
I noticed you are on Verizon, bad cell reception can chew your battery for lunch too.
There's something floating around in the development section (sprint I think) called battery mod.
Of course, youd need to root and unlock your device to get it working (takes all of about 5 minutes).
I also had this battery draining problem, but installing a custom from with a power saver governor and the battery mod, it'll drain 1% every 30min-1hour. Its essentially in "deep sleep", as the CPU winds down to 0mhz, instead of the standard 350. With this comes a lower CPU voltage, so less energy is wasted.
All in all, this is a great phone once you tame it.
Look for Black Ice ROM. Its probably one of the best here because it let's you choose a stock look or a custom look

Rogers Galaxy S3 battery drains ultrafast

Hi folks,
I have had my rogers S3 for several days now. while i love it very much but one issue frustrates me. I get only about 6-7 hours for one charge on a maybe a little bit more than moderate use.
I read somewhere there was an error in one of the system config files but that article was talking about the international version. do any of you experience the same?
My GS3 battery life is going against all the reviews. help.
I had the same problem, I did a factory reset and it seems to be considerably better now.
not sure why the phone kept going into deep discharge, but it hasn't done it since and it's been a week or so now.. is your phone also warm near the USB connector?
The error in the config file was just in regards to the reporting of usage.. Cell Standby usage was being over-reported.. I am not seeing that as being the case on my Rogers SGS3..
One thing I did do is nuke all the rogers installed apps.. I got sick of the VVM+ whining constantly about not being able to work over WiFi.. I just used Titanium Backup to freeze all of the rogers apps.. (rather than uninstalling them).. battery life is quite good actually.. very surprised.

thank you for the info. how is a factory reset done? does that mean i would lose everything i downloaded already? i will give the Titanium Backup a try to get rid of the rogers apps too to see if it helps. yeah, the phone gets pretty warm after a short while.
Are you on LTE, My battery gets about the same with LTE always on since it does consume a lot of power

Well.. this may not be a fix but it really worked forr me. Battery time was at least trippeled.
I drained my battery until the phone shut down, then I connected the charger WITHOUT turning on the phone (allright I KNOW it sounds stupid). Noticed the time to charge it fully increased from 1.5-2 hours to 4-5 hours.
I had to charge the phone during the day before, now it last for 2 days at least.
The cell standby is still wrong but that is just a indication fault, this was a real problem for me.
it's the rogers apps!!!
FYI - disable the rogers apps (all of them) and your battery life will DRASTICALLY increase. I've tested this with them enabled (battery life sucked), and disabled (battery lasted for like 1.5+ days).
Oh and let rogers know their apps suck like I did. The more people that report it the more chance they might actually fix them. A fun way is to do it to their twitter account @rogershelps
If you decide to keep them disabled, be sure to call Rogers and tell them to remove any of the features those apps use...thus reducing you monthly bill.

With root you can either delete them or use titanium backup to freeze them (stop them from running or updating).
I did this (freeze the Rogers apps and most of the samsung ones) and get all day battery life (6am to midnight) with between 4 & 5 hours of screen time.

I've found that battery life is related to cell coverage. If I have 3-5 bars and I'm not using the phone I could lose about a percent of battery per hour and my phone will run at a 40-45 when I do use it. If I only have 1 or 2 bats and it keeps switching between 3g and 4G I could easily lose 6-10 percent an hour and my phone will run at 50 or so degrees celcius. A restart seems to help the phone get a better lock. All this temps were cpu temps.
I just did a wipe/reset and found that this worked for me. I couldn't squeeze out a day with it and now go to bed with 30-40 percent left.
Battery life
My battery life on a debloated stock build was average. I was getting about 16-18hrs on moderate use. I've recently tried CPU Editor battery saver profile and so far its going great. I'll post back on the results after I go through a few charging/discharging cycles.
The forum page for the CPU Editor is here: http://forum.xda-developers.com/showthread.php?t=1798765
[MOD/SCRIPT]CPU Editor SGS3 Edition - Secret to Die Hard Battery
I'm with rogers and my battery is pretty awful too. Not quite as bad as yours, but still not as good as I'd hope with LTE off.
What kind of usage do you have though ? For example I work with a guy who has the same model and was complaining about battery. I checked his stats and was at 35 percent battery with 4 hours display time. If you're getting 5 to 6 hours screen on time that's enough to kill battery. If its in standby for 6 to 7 hours and battery is dying then something is wrong
Sent from my SGH-I747M using xda app-developers app
I've had very similar issues. Tried several ROMs and had charging problems and finally ended up on cm10 and it took about 3.5 hours to charge from 30% to 85%. Then dropped to 80% after only thirty minutes off the charger. Not sure exactly what to do to fix the issue.

SOLVED: ICS Upgrade Myth Dispelled - Factory Reset Does Not Fix Battery Drain

EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.

Nope, the only thing I backed up was pics, music, and video, and I combed through those folders to make sure there were no sys files.
It sounds more like your battery is going bad. You can go to Sprint store and they will test your battery for you.
You might also want to get a battery monitoring program and see what is using the battery up.

its not a ics glitch its your phone lol.. ive never had this issue.. plus with the source kernels coming out and with roms/tweaks already out youcan increase battery life yourself.. because your battey cant keep a charge you bash ics? go back to gingerbread then lol. i can use my phone for two hours and leave it off charger over night and still have at least 50% charge

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.
Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.
This is all known information. That's why you use custom roms that have much better battery life.
Sent from my SPH-D710 using Tapatalk 2
I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.
Confirmed, factory reset battery drain exists.
OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

However bottom line, before ICS upgrade my battery life was great and my Android OS was not 50% of my battery power. I'm not rooted or have any custom anything, after the ICS upgrade my battery drains rapidly. I'm willing to do what it takes to get it fixed, however I do fully put the blame on ICS, I'm using stock everything, the battery is good, something in that update is screwing my battery.
All I was trying to do was give developers, a little insight that the factory reset temporarily fixed the issue, for 3-4 hours before bed I monitored it and everything was good. So hopefully this will help turn the light bulb on in someone else's head.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck

[Q] Battery Life?

I was just wondering if anyone had any tips for improving battery life? I'm currently running MROM and I've seen a lot of people say that it has the best battery life, but I can really only get like 8-9 hours out of regular use.
Are there any settings / tweaks I can do to make it last longer?
Don't use the Facebook app.
Does it actually use the battery that much? Have any alternative suggestions or is it just better to use the mobile site?
The only battery friendly alternative I found was FriendCaster. But since I've switched to using just the mobile site.

I actually have the same problem with you. Ever since switching from MIUI to MROM (which a lot of people say MROM has better battery life), my DInc2 cannot last a whole day anymore. With MIUI I used to get a whole day from 8AM - 10 PM with constant use. Now with MROM, I have to use my backup battery for the first time AND JuiceDefender App so that it can last after 4-5 PM

JuiceDefender is OK if you aren't constantly checking your phone. Pretty sure turning the screen on frequently (which makes JD enable data) would cause faster battery drain. I might toy with it for a little while, but for now I've just uninstalled the official FB app. I'm sure there is some more stuff I could be doing though.
Let me know if you come up with anything.

One thing I noticed that Wifi Sleep Policy in MROM does not work for some reason. Wifi is constantly on even though I choose for it to turn off every time the screen is off. For MIUI, it does work so it did help in the battery life. JD can't turn off wifi either.
Just turn your brightness to minimum. It helps.

I just downloaded it to see how it does compare to Juice Defender and DS Battery Saver Pro. I never really like Juice Defender and have been using Battery Saver for a month and it seems to help my battery life.
Once I have been using for a few days I will report back what I think about it. Thanks for the post tho otherwise I wouldn't have found this app.
Just installed this.... will report back when it's done learning and switches to saving mode.
Thanks for the heads up, i'll give this a try.
nice grabbed this up will be checking it out.
Just posted this in the Verizon Galaxy S III forum as well.
Still seems silly to me that we are going to have to have 4 separate discussions for an app that will work the same on each carrier.
I'm not really sure on what the value of these apps are.
Letting my phone do whatever it wants when I'm on wifi and my phone is sitting idle, my phone uses around 1%/hour of battery life.
Some portion of that is all this app could really save then, right?
Why bother if, in exchange, I'm possibly having delayed notifications, apps not updating in the background, etc.?
I've been running this app .today is 3 day (around) have not rebooted or anything using phone as always honestly don't see a difference yet..

This app just switched from learning to power saving mode. Will see how it goes.

Mine too. I didn't think it would ever switch over. I'm interested to see how it goes. I currently use 5.8% battery per hour. Hope it helps out.

Let us know how it fares against JD and BSP. I have JD Uktmate and have been happy with it. I lose about 1% an hour at night which is better than the 3% I was losing prior to purchasing JDU.

doesnt do anything, i get about 12% drain in 9 hours when im sleeping, what it does just turn off wifi for me if im not in range, which is useless, having wifi on doesnt drain much battery at all
Thanks for the link! Will update in a few days with results
can't tell if it's just a placebo effect or not, but i feel like my battery life is a little better after using this app
I haver never once had a random reboot until I installed this today not sure its related just throwing it out there

After using this for the past few days I would say overall it is not that bad of an app. I am really starting to like it. My average battery usage went from 5-6%/hr to 3-4%/hr. I know there are a lot of variables that go into this but I would say it works as well DS Battery Saver. I have also used JD but never really liked that app. I will continue to use this app to see what the long term would be on here but its a good find in my opinion.
If nothing else try it out for a week or so and compare stats. I use Better Battery Stats to get my info from.
Has anyone compared this to the relatively new "Greenify" battery saving app?

Anything that suggests it saves battery makes me nervous. Because the only way to do that is to shut down apps. And when you shut down the app, it may not get updated, or it may open very slowly when you do need it, etc.
I did not like it much... i am guessing that all this app does is change sync frequencies of different apps. To do it it tries to determine your location so that it can turn sync off/on or change sync interval based on your prior usage patterns.
Once it was out of learning mode, i noticed that my s3 battery drain was quicker due to excessive usage of maps by this app.
I uninstalled the app... and have got my battery life back.
