Another battery life question...

I have a buddy with a droid x that gets RIDICULOUS battery life. What is it that causes such a difference in endurance? I mean most of the other specs basically match up... Is it htc related? Can I get "droid-like" battery life somehow? I'm on fresh 3.3 with netarchy 4.1.9.1 bfs

I havent played much with the DroidX but from what I have read it has a power profile managment on it much like a laptop . I believe that is the part Motorola put in the phone . Profiles like LONGER BATTERY LIFE , or MORE PERFORMANCE . Something Im kinda surprised the EVO wasnt given but I make it thorugh the day on one charge

Are you rooted?

Please keep in mind the apps you downloaded and the widgets you have set-up on your screens. Some apps require to be run in the background eventhough they are NOT used by you at the time, such as Google Talk, Qik, Fring, pedometer, and anything that needs to be "ON"...thats one of the culprit on battery drain you might want to look into.
Having one widget per homescreen is ideal, in my opinion..and learned that by having multiple widgets in one screen, is another culprit in battery drain due to it requiring to work upfront, for example, Facebook widget needs to be on constantly and updated for as long as that widget is there, regardless if you touched/used it or not.
Now, for the MOST OBVIOUS part...turning off GPS, WiFi, 4G, and bs when you DON'T need them, by following hot sexy COMMON SENSE, you should get AT LEAST 3 hours more on your battery. Pure sexy common sense LOL ;-)

Greetings,
I couldn't agree more with all the things you noted in your reply.
I rooted mine, and deleted many apps I don't use, but insisted on starting up
even if I had already killed them in the manage applications section.
But I was amazed at how short the life was in spite of having done that. I quickly
discovered (as you noted) that keeping 4G on, drains the batt.
In fact, for me anyway, it really drains the batt!
Just thought I'd mention it, because it was really surprising to me just how bad
an affect on the battery 4G was - bummer.

Mine usually gets between 36-55 hours on a charge (record is 58 so far) with about 3-5 hours of "use" on the stock battery. I don't use it to play games or watch movies, just phone, internet, email, etc - widgets all over the place. Gmail push is always on as well. In fact, I unplugged it last at 10:50pm on the 28th (34 hours ago) and I'm at 48% still.
The biggest thing I've found is download setCPU and adjust the CPU frequency to 245 MHz when the screen is off. That saves a lot. Other then that I keep it at 998 MHz (max speed) all other times. I am playing around with tasker and turning airplane mode on while I sleep, but that seems to have a minimal effect, saving around 2% over 8 hours. I use tasker to turn GPS off unless I'm using one of my GPS-enabled programs, although that doesn't seem to do much either.
I'm running just a basic sense rom with a stock kernel, nothing special. rooted with clockworkmod and that's all I've done rom/kernel-wise.
If you actually use your phone a lot I'm not sure there's much you can do besides get a bigger battery. If you just use it mostly as a phone and less as a PMP or gaming device you should be able to get some nice results.
EDIT: Oh yea, and don't use a task killer (I don't). From what I've read those can actually cause the phone to consume MORE power as services are being killed and opened constantly. Android is very good about leaving tasks open in the background without them consuming power. Opening and closing them constantly is another story.

I wish I could figure this out too. I've been switching between a ton of kernels and roms and can't seem to find anything with good battery life. My phones been unplugged for about 2 1/2 hours and I'm at 53% battery life. No widgets running and just average usage.
Running virusrom and kings #9 and a lot of other roms and battery life is a joke.

So far, the best battery combo I've found is fresh 3.2 with it's stock rom and I returned to it last night. Some say 3.3 is as good or better but I can't seem to get those same results...
But my real question is, why is the droid able to get such great life?

What I have found to help most of all is to NOT use the Mail app - it drains the battery like crazy, especially if you are popping several accounts. Instead, use the gmail client and set it up to pop your other accounts, and push them to you. This literally trippled my battery life. And it is way faster than the 15 minute intervals that the mail app gives you. Give it a shot, you will be pleasantly surprised.

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.

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.

No problem for the link. There are many ways to help save battery. I for one turn off GPS, Bluetooth, and mobile data when I'm not using them. I use AOSP Roms mostly because they give me better battery life, I use Incredikernel because it regulates how my battery works more efficiently, and I also have an extended battery. Wiping your battery stats every once in a while can help you prolong your battery life as well.
Sent from my ADR6300 using XDA App

optimized sense with the stock kernel will warrant some seriously nice battery life. thats how I maintain mine.

Depends on what I do, through a normal day (texting, few short calls, 30 minutes of music streaming, less than 5 minutes of GPS) it'll last ~1.5-2 days with CM7 nightlies and chad's incredikernel - underclocked 128MIN - ~800max
But if I use GPS all day, which I sometimes do- it'll drop 50% after 4-5 hours of use (this means screen-on, GPS running, also uses 3G data for maps) and I'll usually need to plug it in before the day ends.
I have a 1900mAh battery that fits in the stock case, so this isn't what I get on the stock 1300mAh battery.
If you can't last it through the day it usually means that you are a very heavy user (you like browsing the web all the time, streaming music, texting, watching videos) OR you have a setup that likes to eat your battery.

I need two of my 3 batteries to make it through one day. I use juice defender, and when I stream pandora at work I turn it off cause it interferes. I always have a charger handy too

I actually didn't know that the 2150 was smaller than the 3500. That thing is a beast, my friend uses one and his phone is at least twice as thick as mine.

If you are rooted, you can update the radio, I've noticed much better performance out of the updates cause they seem to manage gps and wireless better. The radio update turn off wireless if you are out of range and turn off gps if no app is using it.

yeah but you have to take into account how slim the stock incredible is. Without any case and with only the stock battery it's too thin (for me at least). Hard to hold onto the sides and I accidentally press the volume buttons often. I've also dropped it 3 times with that setup.
With a case it's great and with the 2150 it was great, loved both setups but I'm liking the new style now with the 1900 and case so that's where I'm sticking at.

Does wiping the battery stats help the battery life? Or is it just so the phone better understands how much battery is left?

Stock battery has always worked best for me.. I also have the seido 1750 mah as well as some chinese versions of 1500 mah.. I use them as backups.. I'm currently using miui as my rom and the battery life is great... I usually get about 24hrs before i'm down to 20%. No way I would make the whole day on previous roms..

I take cues from battery university. Basically, don't let the battery go below 20% shallow charge /discharge

The kernel your running makes a huge difference in battery life. Been using Ziggy's BFS for quite some time now with the Seido 1750. Gets me though the whole day

[TIP]Increase battery life by at least 50%

Here is a tip on how to increase battery life by at least 50%. For me, it has increased by 83%, given that my S II is relatively new (3 months old). It is an app in the market which you can get for free: JuiceDefender
MUST:
Remove any task killing apps (Advanced Task Killer) otherwise this app is useless as it needs to be on at all times.
I have my settings set to Aggressive, as I don't use my phone much during the day.
My normal on the Bombaridier v3.5 ROM by TricH was 100% at 7:00 AM and 88% at 10:23 AM with only 40 minutes of music and standby with no data connection or Wi-Fi. With JuiceDefender, I get 100% at 7:00 AM and 98% at 10:23 AM with the same circumstances of use. It is worth downloading and will extend battery life. I have 83% more battery life according to my math (which is (10/12)=(x/100)) and it is amazing.

I agree that JuiceDefender is an excellent product for extending battery life.
I have the "Ultimate" version.
JuiceDefender alongside "Battery Monitor Widget Pro" is the killer combination...
I did notice one slight bug with JuiceDefender (JD) - there's a known issue with wifi management. Phone turns itself off occasionally. The fix is to simply set JD "disabled" for WiFi management - problem then goes away.
I also listen to music (Pandora) over a Bluetooth headset (about 3 hours per day).
I regularly get about 18hrs+ (combination, on average: 3 hours on voice, lots of email). Stock, rooted ROM... bloat removed.

I agree Juice defender is purely amazing, according to JD stats, I get 1.83% more battery life, that's with aggressive settings.
Ps: Thanks for the Wifi tip

It'll be hard pressed for any app to extend my 3+ days of usage on a single charge. Just sayin..

I just bought the ultimate. I will let everyone know how it goes after a week of using it.

The first thing that came to mind is; haters gotta hate.
I use it just fine with my purposes.
Check/write emails, make calls. Nifty info widgets for updates. I just don't use it for everything because that's just silly. That's the reason why I get such a long run-time. I already have a dedicated media device, no need to watch videos, etc etc on the phone.
Just because most people don't get more than a day usage, don't mean it doesn't happen.

whoa 18+ with 3hours voice is killer.
i barely get about 16 with 2.5 voice and roughly 2.5 display on time

Best thing you can do to to increase battery life is to disable all those Google services. I don't know why but I make it pretty clear in the settings that I do not want any auto-update or syncing of any sort but it happens anyway, so I have to manually freeze all the **** that Google insists on running 24/7.

Thanks for the tip! Extra battery life is always welcome.

Although jd isn't exactly new, but there seems to be a lot of people who just heard of it now. Not bashing but this just shows that there seems to be a lot of new android users or well xda members since the release of our awesome device. I bet most are all former ifags (don't take me seriously).

Lmao. I think this made my day. xD I was using juice defender way back when the droid eris was new and I still do! It works wonders. When I had a dell streak I went from 6-8 hrs of batt life with no usage to over 2 days.

Sorry if I sound like a tool for asking this but if you turn off the Google gmail and calender sync then how do you get your emails?
U have to manually check for mail all the time?
sorry, having issues with my battery also. I use Juice Defender but the free version - everyone that is having success with it are you using the purchase one, Juice Defender Ultimate?

Ive had my phone since october, and the battery has gotten better and better. And im not doing anything special, stock rom, no juice defender, no task killer, nothing of that sort.
I use wifi tether almost all day at work(about 6 to 8 hours) and I still have 20 to 30 percent left when i head home.

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.

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.

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.
-End rant.

I have AMAZING battery life.
I have two........
; )

I bought a 3150 man battery on eBay for 10$. With data on WiFi on . My battery took 30h to be completely drain. 5-6h of the 30h was heavy use ( game, download, watching video)
I'm on cm10 with kt747 kernel OC to 2106mhz UC to 96mhz
Ktoonservative governor
Noop scheduler
All my frequencies are under volt of at least 100mv each
Try this!

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.
Correct me if I'm wrong.
