I'm just gonna say...(Batt issues)

Before I was a behavioral therapist I worked for a small (lol) company called Applied Materials. And there I worked as a project manager. And what I learned there was the importance of following procedure, something most here seem to fail doing. I know I'm not the only one tired of seeing at least 2-3 threads a day pop up complaining how adryns or blah blahs rom is giving you horrible battery life. Have you stopped and thought for a second that it may have something to do on your part? Let me rephrase that, it is something to do with you. There are procedures before flashing...for example, flashing on a full charge is ALWAYS recommended. Second, wipe wipe and wipe again. I hope you don't wipe your ass the same way you do your phone. You stop to think for a second that flashing two themes a day isn't going to f things up with your battery if you're not following proper protocol? Why is it some people don't have issues and some do? It's simple, you f'd it up.

And for the record, the reason I posted this is to stress the importance of following the rules, bc when there really is an issue, it's like "the boy who cried wolf". We don't know which is legit and the other is just some kid too hyped to get that blackhole or superclean and cuts corners.

This thread drained my battery real bad.

It could just be the fact that the Fascinate gets crap battery life in general. I get crappy battery life no matter what. Thanks for the useless post tho. Hopefully mine is just as wothless.

The fascinate is proven to get better battery life then the droid amoung many other androids. I get maybe 16 hours of heavy use. I've been on this forum all day running superclean 2.1 with voodoo and still have 37% left...yeah that's some ****ty battery life for ya lol
Edit: maybe the majority of us getting around 15+ hours are just on some really good dope.

Droid? Which droid? Certainly not the Droid X, I had one and battery life was way better. I dont know anybody that gets more than 10 hours on heavy use. Sure you can get more if you dont actually use your phone as a phone.

Lmfao...really? Then why is my cousin who has an x charging his phone while im sitting here on his couch still posting. Before you post again take a peek...i've been trollon this forum for 12 hours now.

I followed everything to a T the second time around. My first time flashing superclean I was getting less than stellar battery life. Second time around I wiped data, cache, dalvik, and battery stats multiple times while on a full charge.
I've had my phone off the charger for 13 hours now and I am at ~60%. I haven't used it as heavy as normal, but even under heavy load I am getting much better battery than my first time around.

In "16 hours of heavy use", how much of that time was your screen active? You can look in Settings -> About -> Battery Use -> Display. "Heavy use" is a fairly imprecise term, since what one person might consider heavy use might be 'fairly light' to another.

All right, I have to admit, that right there is pretty funny!
I agree with your post, thought. Every time a new rom is released, the next several days are filled with complaints about the battery life. If you follow the procedure for resyncing the battery stats, your battery life will be back.

I get good battery life...so this isn't a fact for me.
The most important thing to keep in mind is battery life is SUBJECTIVE, as are the terms used to define usage (including "good" and "crap" as in the above). What one person considers "light/medium" use might be "heavy" use for someone else, and vice versa.

For me battery life on eb01 is great as long as gps isn't enabled in the pull down shade. When that is on the phone doesn't sleep even if gps is never showing active in the status bar.

X3...imho, it's an irrelevant feature to have on at all times unless you actually need it.

Eb01 battery life is sub par - mostly to with the fact we do not have custom kernels yet. Wait for those and well see the battery life that spoiled us again.

Not percentage, but time.
My Fascinate, currently, has been unplugged for 22 hours. Light/medium/heavy use is all completely and totally relative and opinionated terms. The amount of 'Time on' for the screen is a fair bit better way to show the use than just the meaningless 'heavy' & friends terms *. I've had my screen on for 55 minutes total, during those 22 hours, and am down to 42% battery life remaining. I wouldn't call the use I'd done 'heavy use', but someone else might consider that about as much use as they've given their phone in a WEEK!
I find my battery life is decent, but by no means amazing (I generally always make it through a day, 2 with light usage).
* Even then, it's a fair bit different if the time was spent looking at a single active pixel on the screen, vs playing with an augmented reality app that keeps the GPS, camera+flash, and wifi/3G constantly going, while also burning huge amounts of cycles on both the GPU and CPU... but one step at a time.

Okay, I've been flashing my ass all day long and not one person has mentioned seeing a wipe button appear, so I don't see how anyone can wipe their ass the same as their phone.

In my case it's mostly due to the fact that the phone never sleeps if GPS is enabled. When the phone doesn't sleep, it eats battery at an alarming rate even just sitting in your pocket. Once GPS is disabled in the notification shade, battery life is more in line with DL09. I'll be happy once we get some custom kernels, as a LV kernel seems to help my device a bit, but battery life isn't so bad anymore as to cause me to flash back to DL09.

Battery Saving Tip

Hey Guys,
Not sure if anyone has ever posted this but I thought I would share how I am able to get 2 days plus on single charge...
I only recomend this if you are not totally dependent on your email, facebook, gtalk, etc to sync.
I have my email accounts on my phone but I don't need to receive them instantly meaning they are not dire important so this works for me.
Android's biggest battery killer, which most of you probably know, is data syncing in background and just data connection in general. What I personally do is keep 3G data off at all times by going to settings->wireless and networks->mobile networks->3G Data and uncheck it.
Obviously with this off, you wont be able to connect to web, get emails, download apps, etc... But if you live in a 4G area like me, all I do every once in awhile is flip on 4G from dropdown let it sync or do what I got to do then flip 4G back off so there is no connection anymore... This will save so much of your battery but it is up to you to check things when you need to....
I hope this helps some people because it helps me a lot... I always recommend this to customers that come in my store if they are not depending on work email and such...
Let me know if you have any questions!

You can hold down the power button and click Data mode to toggle 3g

I have done those things since I've had this phone in august and everytime I talk about getting great battery life the haters come out and say well you didn't have sync on blah blah. Freaking retards. Especially if you are sleeping why not turn off sync for the email that is not going to come anyways. I haven't seen the battery life yet as I did since eclair though.

Actually my biggest killer is display. Our devices our the only ones with 90%+ battery usage for display, yet they advertised that it required 20% less battery!

I know! The display is a killer but even so doing this with full brightness and I can still push a day and a half... I usually keep my brightness all the way down though and manage to push upto 3 days...

interesting thread i am going to try some of these suggestions

I get 56 hours using Ultimate Juicedefender.

Wow...i use to get great battery life. I'm using lowest brightness setting, sfr, and ultimate juice defender and getting only like 16 to 24 hours of life.
What else are you guys doing? I use to get 50 hours but not anymore..
I thought I knew all the tricks in the book. But I use my phone constantly. Above average I would say.
Sent from my SPH-D700 using XDA Premium App

I am not sure, I keep lowest brightness and keep data off almost all day except for occasional checking but maybe 10 minutes total of data being on... I have noticed with EC05 battery life lowered even on complete stock... Most people in my store hve epics and all have suffered worse battery since the update... It didnt matter if it was OTA or OTW...
Maybe try and get a new battery...

I think the reasons the 'haters' come out is simply because you're stating your getting better battery life and then revealing you're castrating your phone. It is a smartphone after all. It's supposed to do all those things you turn off. This isn't a phone which is only supposed to make calls. I mean, if I wanted to check my email once a day, I'd simply do it while I'm in front of a computer.
I don't believe I'm one of said-haters but possibly providing a bit of information on where they're coming from as well.
I think it's well documented that Android phones pretty much suck in terms of battery life, especially when compared to Blackberry. Man, RIM got it right on that aspect.

How is that castrating your phone? I can still do everything else on the phone... You don't need a constant data connection to use it like a PDA. Do all tabs have a constant data connection? No, so are they not going to be considered PDA because they lack internet sometimes? no
I am sorry to say but if your managing your phone and doing things to better, that is not castrating, that is good device management and what should be done so it runs how you want...

Well, it sorts of like taking a porsche and not pushing it past 2nd gear. Some people are happy with it, some are not. On one hand, battery saving posts can be thought as misleading, if the premise is that you dont compromise any functionality. I prefer to charge my phone everyday and not worry about battery, but when your battery is dying when you need it in the evening, than one is of a different opinion entirely.
One thing which I realized to late, is if you are at work in the office or somewhere with wifi, you can toggle 3G off and not lose any functionality, since wifi uses a lot less juice.

I have tried I new battery, I have three that I alternate between. I have no idea what has happened to my phone. It could be the phone itself

And I did say from the beginning what it does and what you loose from it... The only reason it was posted was to try and help people who may be newer to android and needing to squish extra minutes out of their phone for the day... Or they may find themselves not near a charger and almost dead and need their phone so turn off data to preserve the battery... I mean it doesn't "cripple" your phone to turn off data... I can still play angry birds, check my calendar, call people, text, etc. You don't need your phone to have data to use its features...

GingerBattery Sucks?

I dunno man, just gingerbread itself appears to have fubared my phone. I wiped sd, wiped phone, factory reset, odined stock EC05 and took the forced EI22 update. Even still, android system chews through battery at >90%. A small thermonuclear power plant could not give my phone enough juice.
This coming after I tried multiple combinations of roms, kernels, uninstalling apps, and freezing data sucking apps that caused high wake locks....
I have tried stock gingerBreadEI22, ACS 3.5 - 5.5, ERA RC1 & 2, and Random Rom, with nubernel, different samurai kernels, and just whatever the chef cooked up. All the same, excessively high "system" battery usage.
Anyone is / was having the same issues and able to iron it out?

That reading for system is the norm. I get 24 hours with like 80%
Sent from my SPH-D700 using XDA App

I agree with Alkah0liK, but with my experience so far, if I don't use the phone all day it doesn't really use the battery, but as soon as I start talking, listen to music, or web surf it because a pig. I actually want to go back to 2.2 and use frozen rom again from ACS again. Can't figure out how yet though

Ok thanks, I was wondering what others were seeing.
I must be doing something it does not like. I can go a couple minutes with the screen on (at lowest setting mind you) and watch the battery drop 2-3% or more, almost dead battery within 10 - 12 hours even in /out of airplane mode...
Is there something really wonky with CWM? Funny thing is this started happening right about the time i switched over to v5. I am in the process of reverting back to wiping everything, odin to EC05, and going v3.1.01 again.

The battery life is better with gingerbread, but its not going to make your phone run 2-3 days on one battery life. Sorry my friend, those days are long gone. It would be very hard to find any cell phone that can run for longer than 24 hours these days.

No I get that, but I was able to use my phone for more than a couple hours a day before gingerbread. B4 the leaks I was running Viper Rom EXT4 with genocide at 1200 ondemand and still getting through the day. If I cut it back to 1000 and went easy I was only charging overnight to bump it back up to full.
I was even using RandomKing's and ERA's leak based roms with EH06 & EH17 without any issue. For me it really has been either the EI22 / CWM5 / latest roms.

Hey alky, I was also in your position. I tried every rom you tried, with minimal pleasing. My advice, if you can live without 4g, flash the current cyanogen and set the render effect on night mode. Enjoy a thorough battery life my friend. Nothing beats it thus far. Can't wait till we see cm9.

Thanks! That was actually going to be my next try. I only get 4G when I am downtown, not very much as of late anyway.
FYI- I have found what I suspect as two possible culprits on ACS 5.1 & 5.5, and ERA RC1 & 2. According to better battery stats CM_VnoteService and *Sync for GTalk will run and run and run unless you open the applications and go through initial setup. Those two process will stay stopped so long as I leave them open / connected, once I close them - the partial wakelocks restart and run until you open the apps again (or just uninstall).
Even with my obsessively high amount of .acore launcher time and better batter stats application usage, they are still well below the "system" usage under the process dropdown.

It definately sips battery when not in use. Although I feel I get more screen on time with ACS ICS. I regularly have over 3 hours of screen on time with GB, I don't remember getting 3 hours on even SRF 1.2.

Turn off your syncs. If there is no signal your syncs will keep trying and burn up your battery. Turning off data mode in low to no signal areas will conserve battery.

Make sure upgrading to GB did not change any syncs. Also make sure new apps aren't loading into memory and sucking battery like Talk or Google +. Grab Memory Booster lite and pull up the task killer to see everything loading on your phone. The stock task killer sucks.

I recommend paying the $50 for battery and portable charger/storage unit. I'm a stock user who just had 41 hours with my new battery with 2hrs of screen time. I really like having two batteries too. No more charging cords connected to the phone...ever
Edit: the batt. I bought was a stock 1500mah batt. and charger kit from a sprint store. No regrets

Still running 100% ERA Legendary v4.0.1 (with provided kernel) and I squeezed ~74 hours of pure standby time out of my stock battery.
Data Sync (FB every 6hrs, Weather every 2hrs, Google push)/GPS/Auto Brightness = on
TWS = 4%
Display Time = ~24mins (sent 3 texts and checked 1 voicemail)
100% on 3G
Had I turned off all synching, GPS and lowered brightness all the way, I would have probably gotten 4 days.

Battery life has heavily depended on the strength of signal for me as well. I moved recently and have been living in the basement while the renovations are going on upstairs. No airave (it is used at a different location) means little to no signal in a brick house due to Sprint's POS signal frequency. Although I've been flashing different kernels and maybe not allowing them to settle + undervoling a bit (very conservatively, will not OC over 1100). But it is true that since days I was on BB Tour, not one phone lasted a full day without an extended battery. I'm pretty much decided on VZW switch once Prime comes out - one of the factors is better expected power management of ICS and possibility of adding an extended battery without worrying about making the phone too bulky (given how thin it is).

Man that sucks, I've always had great battery with gingerbread. Right now I'm on RC2

Best setup for battery life in MIUI V4?

I'm currently running 2.4.6 along with nyan colonel 4 but so far I'm not too pleased; I'm getting about 5-6 hours with medium use on a 1800 mAh battery.

Try turning off 3G (mobile data) when not in use. I was getting 6-7hrs w/ it on & now I can squeeze out 12-15hrs. However I left it alone it went 30 some odd hrs w/ only 30mins of screen time though.

Nuh uh, that's not gonna fly in this thread. I shouldn't have to be turning off my data to get any semblance of decent battery life. I really do want to get this to work though; I love MIUI. Unfortunately it seems the GB version will never be complete as everyone jumped ship to ICS and the ICS version is awesome but seems to get crap battery life even on 4.0.4

you dont HAVE to turn your data off....but if you wanna save some battery that is one of the best ways. if your phone is in your pocket and you dont need it, why have it on suckin juice....try juice defender, i use it with any rom i run and it helps...play with uv in nstools, just dont go too crazy with it.

Uh lol? He just gave you the best tip and you turned it down, you must not be interested in improving battery life, if you're constantly using data and have over 2hrs of screen time you're asking for crappy battery life, and unless you are always receiving important emails, you really don't have a reason to run it 24/7, if you're to lazy to turn it on and off, just use juicedefender, and it'll do it for you. You'll have to make some sort of sacrifice, whether it be monetary or personal. Phone usage is everything, get a bigger battery. Also, logging out of social networking apps when you aren't using them helps as well. I find I have very nice battery life on MIUIgb

I know that turning off data can save me battery life. That's not the point of this thread. I figured it was implied I was talking about different kernels and versions of MIUI V4, not the way I use my phone.
On that note, what's your setup with MIUI GB? I've been considering going back but I'm turned off by MMS STILL being broken

Sorry dude but that's the wrong question to ask. By now u should know that every phone is different if its what kernel to use & what setting to use this or that app than its simple trial and error. When we were still on froyo I couldn't use one of the very popular kernels bcuz it drained by better like crazy it took me a few weeks but I found the perfect setup to get good battery life. & sorry for misunderstanding your intention for this thread.

Alright.. well I misunderstood, it mighta been better to include that in op but it's whatever now lol, I'm using shadowkernel MIUI, and... 100-800Mhz governorndemand, schedular: Sio. And yes MMS has actually been a pain in the ass today for me, I'm considering going to AOKP again lol. I will apologize if I sounded rude in the previous post though, I didn't understand where you were coming from.

Is dropping down to 800 MHz noticeable as far as performance goes? Also is MMS the only problem you have with MIUI GB?

[ICS] We need your help... Battery life...

Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

Eclair
Just Eclair
Any Eclair
Shoot me......
But seriously, disabling 3g on ICS saves a ton of battery life.

Uhhh,,,on ANY ROM...but not a practical solution.
I think the OP is looking for more practical solutions where they are not disabling major features of the smartphone.

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.

He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.

PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Think about if your screen was on while the device was awake..your time would be cut in half

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.

Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Something we can all get behind here... I remember I used to get 24+ hours on froyo w/o customs kernels. Le sigh..

-I don't use the supercharger, but I do apply the same oom ram mods. These help close unused apps when they exceed the applied limit. Based on my experience, it's kept apps under control.

-THIS +9000! An app that spends all of it's time stopping other apps is wasting just as much "battery." I maintain, Advanced Task Killer, with NO, I repeat NO AUTOKILL. Set a widget on your home page, tap it occasionally to make sure everything is closed. Same effect as the built in task manager, but one single convenient tap.

-These numbers are pretty much the same for me. I almost always average 3 hours display on the stock battery between games and internet. 5-6 hours on the 3500, but I'm pretty sure it's not reaaallly the 3500mah it claims to be... . I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

I don't turn off my connections at all and get great battery life... and seens how the op states don't say anything about disabling 3g or anything id say your comment was the least helpful on the thread... but at least you tried... don't get into a battle of witts with me, I'm afraid your unarmed...

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.

Please follow the format specified by the OP. List the 7 items. Bickering in this thread will not be tolerated.
Thank you for your cooperation

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.

- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Using AOKP with shadow kernel.
Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.
