[Q] Maximize Battery Life

Hey there,
I want to know what is the BEST setup to maximize battery life. What ROM? What Kernel? What UnderVolt ( if any )? What Radio?
My room mate has an iPhone that he modded and it now lasts two days without being charged and that's with moderate usage. I'd like to out do him with my Android. Any help?
-Reiz

So far personally I've had the best experience with the following :
ROM : CM7 ( 7.0.0 )
Kernel : Tiamat 2.6.32.27
Radio : 11.19
I can't seem to get undervolting to work since I don't have the folder that Viper describes even though I am using an AOSP rom ( as far as I know ) . o.o It's odd really... Anyways, that usually gets me about 20 hours of usage or so .

Twenty hours isn't bad, as the Incredible isn't known for it's battery life. You won't get what your roommate's getting with his phone, maybe get a bigger battery...? I don't think you're going to really out do yourself with the experience you've posted, I'd be happy with that.
I am running SkyRaider 4.0, Chad's 12232010 kernel, OC'd to 1.0368 (small OC, I know) with the leaked 04.08 radio, and I can get about 20 - 24 hours before charging, low to moderate usage (no games, emails for work/personal, maybe 1 call of 5 minutes, lots of web browsing).

Cm7 stock kernal. On metro pcs with a seidio 3500 mah extended battery. Unplug at 7am 12 hours later only sitting on 74% lmao. And in that time bout 100 text. And 200 work emails.. and 30 mins of surfing on lunch. This setup has been the best for me on bat life.. used to run sense and my bat life would just suck..

Two things that will kill your battery faster than anything:
-Anything that syncs
-your screen
So, turn your brightness and screen timeout down and turn off anything you don't need syncing all the time, or at least turn the sync frequency down.
Also, keep your wifi, vibration, tactile feedback, and gps off unless you really need it.
Kernels, roms, undervolting...no where near as effective.
Think about your phone as a smaller version of a laptop (which it pretty much is), what's going to save you the most energy: throttling your cpu speed, or turning the screen brightness down?
Much love brother

better battery life

I've been using CyanogenMOD 7 and love it (mostly). The one thing I don’t like about it is the short battery life. I'm kind of new to rooting phones so it took me a bit to get it rooted and get CM7 rolling. I was wondering if there are any mods out there like CM7 that have better battery life? Or if there's any thing I can add to CM7 to give it more batter life?
I've been using android since the first phone came out so I’m already knowledgeable in what to turn off to try and extend the battery life, but I have noticed a big decrees in batter since installing CM7.
Thanks for the help guys

You can under clock the processor when your phone is asleep. This creates better battery life.

your phone automatically underclocks your processor when it sleeps (for most CPU governors), you do not need to tell it to do so.
I'm not picking on you fyi, I'm just making sure we are giving people accurate information... there's only one thing worse than no information: incorrect/incomplete information.
op: which version of CM7 are you running? remember, the more minimal your setup (ie less homescreens, less widgets, manual syncing of gmail and whatever else, etc) the better your battery life will be. this is especially true of newer phones that are getting heftier cpu & gpus that, while intelligent with power consumption, are going to drain even larger capacity batteries relatively quick with moderate/heavy usage.
how long are we talking with battery life? how heavy a user are you? for reference, I get around 16 hours of battery life if I don't charge the phone at all from unplugging to battery dying with moderate to heavy usage (texting ~50 times a day, sometimes up to 100 emails depending on what's happening at work, couple hours of calls, couple hours of streaming music [pandora or audiogalaxy], couple of hours of games [peggle and plants v zombies mostly - both of which are resource hogs], etc).
I have just learned to get used to the fact that the phone is going to die if I use it a lot, so I've purchased three micro-usb cables and a car charger.. that way, unless I'm in an area where there is no charge-capable usb port nearby, I'm always able to get a little more juice if need be.

but i also mean setting the max sleep to 368mhz. by default its set at 800mhz. sometimes with apps running in the background, the processor may go to 800mhz without you knowing

check out 'powersave' and set your cpu max to 806mhz. should last you a nice long time like that. responsiveness suffers, of course.
'ondemand' and 806mhz is the best comprimise for me. still fine with HDvideo recording, streaming audio, Nav, etc
if you really want to make it last... clock down to 400mhz, turn off all the sync, set brightness and timeout to minimum, all the radios off (airplane mode), and the volume down, on vibrate.

But some govenors don't drop the sleep to the lowest profile. In fact almost all keep it above the lowest clock. Other kernels allow it and you can also use third party to set it lower. When the tweaKr script becomes universal it will be even better =)

It suffers in powersave because it stays at the lowest setting only. No reason to set to 806. Lol and that bottom comment is hella funny =), but if he does that his phone will just be...a waste of pocket space.
Your best bet is to do some research on kernels. If you are using cm7 to cm 7.0.3 id recommened pyros kernel. If you are on 7.1 or a nightly over 121 I believe id go with eugene's streamline5. It did wonders for mine Also there is a battery saving tips. Google G2 battery saving tips. Should be first link that comes up.
Cyanogenmod roms are known to be battery hungry. Nom nom nom.

Mugen 3600mah = better battery life...

Can you elaborate on what kind of battery life you are getting now? How many hours, and for what level of usage?
How long have you been on CM? It takes a couple charge cycles of the battery after flash any ROM, for the battery meter to be accurate. Clear battery stats (as mentioned) then charge to 100%, let drain to about 20%, repeat a couple times. Don't drain until the phone dies. Some people say to do this, and its not good advice. Over discharge of Li ion batteries can cause them to no longer take a charge. There are people on here, on the Vision and other phones, that let their battery drain to empty, then the phone would no longer boot, forcing them to replace the battery.

How much screen time do you get on a charge?

Hello there fellow Galaxy Nexus owners, I am trying to figure out if my battery life is normal/abnormal and am hoping to get some data form other users. If you could please post
Screen Time:
Brightness Setting: (either as a % or auto)
LTE or GSM
And if you want maybe info about 4G/3G/Wi-Fi and what you do when the screen is on.
Mine recently has been about
ST: 2.5 hours on average, maybe less
Brightness: all the way down most of the time
4G off, on Wi-Fi most of the time, web browsing/ texting

Usually 4-5 hours screen on time with the Samsung extended battery on my GSM Nexus. Wifi doesn't seem to make a huge difference
Sent from my Galaxy Nexus using xda premium

Screen Time: 3.5 hours
Brightness Setting: close to 0% about half of the time otherwise auto
LTE
I turned of 4G most of the time; nly use WIFI indoor.
And battery use shows 65% of screen time with moderate to low use.
I don't play games on my phone.

Screen tine is 4-4:30
On official extended battery
4g is always on but it mostly sleeps cuz I am always on Wi-Fi
Brightness is auto

about 4.5 hours screen time. Only 4g zero wifi. Screen set to auto. 2000 official extended battery.

4-5 hours screen on time with extended battery. Wifi ALWAYS on, bt & gps off, 4g off most of the time. Minimal sync settings. Lowest brightness.

GSM - 3G always on
Brightness 25% to 50%
I get around 3h to 3h20m

I can answer this thread easily.
Gsm stock battery: 4 hours screen
Gsm extended battery: 5 hours screen
LTE stock battery: 2.5 hours screen
Thats what most people get.

I would love to know what people are doing to get good battery with this thing. I just got the phone yesterday, the LTE version. I have the Verizon 2100mah extended battery.
I am at 6h 12m unlugged and at 35%. My on screen time is 2h 2m.
I am on 3G in a good coverage are. Phone sleeping when off but sucking battery when on. I am running 4.0.4 with auto brightness.
As soon as I unplug the phone and use it a little it runs through the 90's like nothing...The first few drops are like immediate.
If this is the extended battery I cannot image the standard one. I hope someone has a suggestion or this thing will need to go back. I was just starting to like the device coming from an E4GT but battery on that was great.

There isnt much you can do for the LTE version. For some rrason it just gets less battery life than the gsm version.

Even with LTE turned off! Man, this is sad. Here I was, thinking with a 2100mah battery I will be more then good for a full day of juice...
I am curious to see how the stock battery can be worse. I might just try it tomorrow...Man, this feels like the days of the EVO 4G.

Thats my best so far :
Galaxy Nexus GSM
AOKP B22
Leankernel 1.7.4 exp. 2 230Mhz
Default GSM Battery
Displaybrightness always at 40%-50% static
SetCPU:
Interactive X 350 - 1200 MHz
ScreenOff Profile
Undervolted (about 100 mv over all frequencies)
I know there was a small charge in between when i had i plugged in my Laptop, but its just a small charge maybe 5%.
At the moment i get 3,5h - 4h with latest Leankernel on AOKP b 23

I get no more than about 2h 20m. Everyone seems to get 4+ hours but they must have no sync settings, no e-mail, no friends, and only be on wi-fi

kind of sad the LTE version has so much worse battery life, I still can't decide if I want to keep the phone. Other phones should be getting ICS soon and the battery life on the GNex is killer.
It is really sad because I get a very slow drain when the phone is in deep sleep, but as soon as that screen comes on, oh boy does it drain. I probably lose 4 or 5% over night (~ 8 hours).

Doesn't make sense. I am running a 2100mah battery on the LTE version and people on the stock GSM battery which is even smaller then the stock LTE one can pull 2-3 more hours of on screen time?

Verizon Galaxy Nexus 3g browsing battery life

My web browsing battery life is horrible. I turned off 4g and I still see my battery drop roughly 1% every minute. That means I don't even get 2 hours of screen on time. The battery drain also seems similar when on 4g so there really isn't a difference. My wifi battery life is a little better. I can maybe get 2.5- 3 hours screen on time. I switched my battery for a qcell 3800mah battery, yet the internet browsing battery life still seems to be the same. Roughly 1% drain every minute. With wifi and the new battery I get roughly 3.5-4 hours screen on time. I have used a number roms from CM10 to Aokp to Jelly Belly, and am currently using codename android and recently switched the kernel to air kernel. My screen brightness is usually 60% and everything like gps, nfc, and auto sync are normally turned off. Is there anything I can do the get better battery life such as using a different radio or is anyone having similar battery issues? Thank You

It is hard to get awesome battery life on the VZW version. I have been dealing with the same. I honestly think my issue is the newness of 4g. I cane from iPhone and inc2 which in my opinion had the best battery life of current phones.

There's nothing wrong with that battery life/screen on time. There is no other Android phone that's going to perform a great deal better than that on 3G/4G with heavy web browsing. You're expecting more than what exists in the public technology and hardware at this point in time.
Sent from my Stock AOSP Android 4.1.1 Galaxy Nexus

I appreciate the replies and feel a little better that I'm not the only one having problems with browsing over 3g. The weird thing is though, that I'm still getting less than two hours of screen on time of straight browsing with the extended 3800mah battery. Wouldn't the battery be at least at 3-4 hours cause its double the capacity. Also what are the temperatures of your phone after heavy use, because the top screen area of my phone gets extremely hot and the temperature can get to 120 degrees.

Try out SetCPU and if you like it, support it by buying it in Google Play.
I use Franco's nightly 241 with the GPU OC'd at 384 and the CPU underclocked at 1GHz. If I start seeing the phone get jittery, I bump it up as needed and the kernel supports up to 1.8 GHz. If I walk around with it at 1.0 GHz, I can get moderate to heavy use out of it from 7:30 to about 6:00 on the stock battery.
The versions of SetCPU that are up on that post are over a year old. If they don't work (which I haven't tried them on the gnex), just test one of the free ones on the market.

Why Do People Complain About Battery?

I've seen so many threads here and at The Verge that I just don't understand. I've been using Android devices now for about two years and I've NEVER had a problem with battery life being worse than my iPhones. I have a 3GS and the battery on it dies after about 8-10 hours of moderate use. Meanwhile, I'm at 12 hours on my SGS3 and 50% battery. I also have quite a lot of applications running in the background. Granted, today I have been low usage, but yesterday I was on the phone for hours and I still went 12 hours before the battery icon turned yellow. I haven't HAD to recharge before 12 hours for ages, even my Atrix went longer than that. I even have a screenshot from a few days ago where I went 14 hours and only dropped to 63%.
Are people just nuts or what is going on here?

People expect to play games at max brightness for hours and still get 12 hours battery life.
In with you, I use my phone constantly through out the day, I run my business from my phone, and routinely get 14+ hours per charge no problem. I just made a few tweaks, nothing big, and I'm good to go. This phone lasts noticeably longer than all my previous iPhones 3,3g and 4. Plus it charges twice as fast as those and never over heats... all my iPhones would get so hot that I couldn't charge them in the car with out testing then in an ac vent, and that's just from half an hour to an hour of talking... sgs3, I can talk for hours with no overheating, and it charges like a boss.

Before I flashed Cyanogenmod on my S3, I rarely reached over 10 hours of battery use with data on.

Neither one of my galaxy phones overheated to where they shut off until one decided it was dirty and jumped in the washer(rip 1st sgs2) .
I had changed my iPhone 4 back glass to one of those metal backs. Now when its on charge it will almost burn your hand if ur holding it. And I have had it shut off while on Facebook. Battery never last very long on I phones if the brightness is up data going WiFi seeking and jbing.

people complain even though they jumped from a 3.5 to a 4.8 720 screen device. Faster processor etc. With hspa or LTE speeds. I mean really. lol

My battery life is great! Much better than any other phone I've owned...12 hours of use for me is nothing....I get 18+ without a problem....frequently I've gone well over 24 hours.

Chargers. That is all.

I think some phones came with defective batteries. I'm running juice defender and could easily make it through a 16 hour day. 3-4 hours of screen time was not uncommon. 3 months later, and I can barely get 10 hours of use and 1.5 hours of screen time. Time to get a new battery!

I am not sure what is going on. I don't have the best battery life I can get 10 to 12 hours moderate use. Steaming music, reading rss feeds, checking email, 2 to 3 hours screen on. I would easily last a day on my iPhone 4. I have juice defender, lowest screen setting, custom kernel with under volting. I think it has something to do with my area. Att is so congested in my area I am barely able to use data sometimes. It's better with lte but still an issue at times.

People use their phones differently. Just saying.
If I don't turn the screen on, with LTE data, my phone dies in 9 hours (I tested it). And this doesn't mean there's a problem with it. I have around 15 different push notification apps running in the background, all of which are using data almost continuously. I don't think I can expect it to last much longer. And if I know I'm not going to be near a power source for longer than that, I simply turn off syncing to get better battery life.
To me, it looks like the LTE radio is the biggest battery hog. Let's see if the iPhone 5 can somehow get around this problem so that other manufacturers can take note

I was going to mention this. I noticed a significant improvement in battery life once I used JuiceDefender to turn off data while my screen is off. 4G LTE is the main culprit of most of the complaints for battery life (in addition to brightness). That is going to be a big problem for the new iphone if they can't get the battery management for 4G correct. It has taken Samsung a couple of years to get the battery working decent with 4G. I have my doubts that Apple could top them the first year running LTE on the iphone. Who knows, maybe that will be the "new" feature they have been working on over the year, LTE power management. That's the direction Motorola has headed in their new RAZOR MAXX devices. We'll see, either way, the consumer comes out on top as we have more competition to drive down prices and receive better products each year.

Best battery life for SGS3
With AMOLED and Android u gotta take special measures to get good battery life:
- kill bloatware. NostalgiaTurboSlim script will help. Or freeze unneeded apps - like Maps and enable them only when needed.
- disable various notifications - Play Market, WiFi etc
- disable ads - root and download AdAway app - they steal your mobile traffic, battery life and make you blind!
- put dark nonLive Wallpaper
- remove any widgets you don't use. I just removed all of them.
- disable animations and transitions
- disable haptic feedback
- disable touch tones/sounds/vibrations
- try using nonAuto brightness (I gave up on that - sunlight does not allow me to change anything manually)
- disable autorotation
- use dark Opera browser user.css
- use inverted or dark themed apps and Gapps, there is dark MMS, Twitter and Facebook in my ROM
- downclock CPU to 1GHz, or enable PowerSave On.
- use modern KToonsez kernel with PegasusQ governor, it downclocks CPU during screen off
- use CPU1 disabler script if your ROM/kernel supports it
- keep chargers around you, buy them at amazon
- buy spare OEM battery - I'm against aftermarket batteries, they are all fake rated
Or just buy latest iPhone 5 and enjoy.
Remember: Android is for tinkerers! That's why we love it! :victory:

Why do people still use some sort of battery management app life JuiceDefender or the like.
GET RID OF THEM NOW !(most of you that use it are probably coming over from an Iphone so you may be new but aren't well educated in how the Android OS works)
This phone comes with its own Task Manager as well as removing unwanted apps that are running in the background that you have previously used and don't need running.
So get rid of these dumb apps that don't do anything.

I believe this is the software bug that can be fixed in one of the threads around here. It deals with the Cell Standby that drains the battery.
