Answers on battery life.

I've been seeing a lot of posts on crap battery life around here, and I was chasing my tail about some of them as well, following a lot of misinformation even by senior members. I think I have a good handle on it now, and picked up most of these tips from these forums, so I'm not taking credit for these ideas, just collecting them in one place. Some of my suggestions assume you have root and Rom Manager (see the Tips and Tricks sticky thread on how to get them).
1. If your battery drains in less than a day on standby, you probably have a bad flash of the JI6 modem (either from the OTA update or from a ROM). Flash the JI2 modem from here "www dot teamwhiskey dot com/home/downloads". If the flash fixes it, you may try going back to JI6 if you want, and it may stay fixed. I went back to JI2 and didn't bother going back to JI6, but it has worked for others. With JI2 and 3G on I get just over 24 hours in normal usage.
2. The #2 battery drain on standby is 3G. I turned it off (Settings/Wireless/Mobile networks/Network mode/GSM only) and my phone lasted for 40 hours on Edge with light usage (few phone calls, messaging, quite a lot of web surfing, 2 hours of podcasts). Didn't even feel too slow (I get 140kbps on edge). Can anybody suggest a really good widget for turning 3G on/off? I use the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.
2.5. WiFi always on is a huge battery saver! It keeps 3g off. I can easily get 3+ days with light usage on my home wifi. Settings/Wireless and Network/Wifi Settings/Menu/Advanced/Wifi Sleep Policy/Never.
3. Don't need a task killer. I wasted all my time killing tasks trying to chase down my crappy battery usage, but since I fixed my modem and turned off 3G I know that the 3-5% CPU usage at idle does not hurt my battery. Taskiller for me was actually hitting the CPU constantly, lightly but for no reason, so I got pissed and uninstalled it.
4. Install a CPU usage monitor like Usage Timelines. It sits in the notification bar, very easy on the battery, but tells you if you have a rogue app pegging your CPU and draining your battery. These are the only apps you should be worried about killing. Astro File Manager has a task manager that shows CPU usage for each app, so you can kill the rogue one. I shoot for about 5% cpu usage at idle (at 200mhz - at 100mhz it would be a bit higher).
5. The app Autostarts lets you disable any app from starting on boot or other events like connectivity changes. This is not strictly necessary unless you have a lot of crap apps installed on your phone and they like to start themselves and waste CPU time behind your back.
6. If your battery reads less than 100% as soon as you unplug it from the charger fully charged, or your battery meter sits at 100% for a long time after you unplug it, you can recalibrate your battery meter. To recalibrate: 1) charge your battery to full, 2) unplug, 3) reboot into Clockwork Recovery and 4) Wipe battery stats.
7. There is No Such Thing as "battery reconditioning" (for all intents and purposes). The above procedure only RECALIBRATES you battery METER to read on a more linear scale between full and empty. It DOES NOT make your battery last longer, period. Whoever tells you that is a moron. If your battery is dying in 6 hours, doing any amount of calibration will not make it last longer (I've tried).
8. I wouldn't be too worried about undervolting, overclocking, kernel tricks and superawesomefast ROMS. The CPU drain at idle is so minuscule (as long as you don't have rogue apps) that those things make precious little difference. Like I said, the biggest drain is 3G and other radios. Having said that, I run Bionix 1.9 with the JAC kernel. It drained my battery in half a day at idle until I flashed the JI2 modem. With JI2 it suddenly started lasting over 24 hours, and once I turned off 3G, over 40 hours. I like this ROM and see no need to switch, it's very smooth. But you should be able to get similar battery life on a stock Vibrant.
9. I have GPS on, WiFi never sleep, auto-brightness, and a few widgets on like Weather and friend updates. I have no fancy settings, literally just turning off 3G (or wifi on, which is the same) got me 2-3 days. So I wouldn't waste time fooling around with magic settings (other than wifi never sleep), battery saver apps, etc.
10. If your screen is on all the time and you're playing games nonstop, you're draining your battery quicker than any of the things I mentioned above, so you probably don't care. In that case an optimized ROM/kernel is probably your best bet, especially JIT in Froyo. You can probably save on screen brightness as well.
If you guys have any other tips I'd be glad to add them to the list, but I hope this gives you an understanding of where your battery life is going. Basically: bad modem, 3G, or rogue apps.
Also, I hope this will put an end to trolls calling people whiners for complaining about battery life and saying unproductive **** like "you're a whiner" or "the Galaxy S is just a battery hog, live with it". It's not, you don't have to live with it, nobody should have to, here are your solutions.
Good luck.

A few things I do to help with battery life is:
Disable Audible touch tones
Disable Audible selection
Disable Haptic feedback
Disable SD card notifications
Set animations to NO animations
Uninstall media hub if you dont use it
Disable auto brightness adjustment
Disable power saving mode
I disable the last 2 and just swipe the notification bar to adjust brightness. Granted these items really only work when using the phone but I can go about 2 days of normal use without a charge believe it or not.

yeah disabling 3g has always been the best option for people really, really concerned with battery life.
But it's kinda hard to tell people not to use 3g on their brand new 3g capable devices.

You may want to add how to test if you battery is bad. If you use you phone repeatedly while it its plugged in you risk overheating and damaging your battery. Signs that unitas is the case are very quick drain and long (7 hours) charge times. You can easily test and see if your battery its damaged. Remove it from your phone and place on flat surface (e.g. Counter top) try spinning the battery. If it rotates easily and quickly you battery is bulging, this is a sign of damage. Time for a new battery.

Thanks to the OP and other contributors in this thread.
I flashed a ROM with the ji6 modem and battery life has been noticeably ****ty since. Example - this morning I unplugged my phone at 7:30 am. 100% charged. It's 10:21 am and my phone is at 75%
In the last 3 hours I browsed the web for 10 minutes while having my coffee and a smoke before heading out to work. Blue tooth was on for my drive, and I've sent 2 text messages. Aside from that my phone has been on stand-by since I unplugged it 3 hours ago.
I'm going to try to flash back to ji2 tonight as the battery usage was definitely better. Will also look into the 3G thing.
Thanks again.

You forgot to mention the two DRM and one downloader services that run resident on JI6.
These were the cause of my reduced battery life after I upgraded. Killing & removing these processes restored my battery life back to normal

I just tried this - switching 3G off works fine, but switching 3G back on didn't work for me. I had to re-boot to get 3G back so this is a no-go in my case.

I know how to kill the processes for the DRM and downloader but how do I remove them?

OP thank you for putting together the list. But I've never seen the point of doing all this. Its like getting a lamborghini and only driving 40mph because it you don't want to waste gas, whats the point? Either get a second wall charger to charge at work or a car charger. Heck even get a second battery if you are out for a long period of time.

You don't need to disable 3g.
The point of my post is to avoid people wasting their time with tweaks that have little to no effect on battery life. I'm telling people that they're wasting time killing apps and optimizing cpu usage and twiddling their settings when the radio drains most of their battery on standby anyway.
Meaning no matter what changes you make, you can only hope to improve your battery life by a tiny amount, because any other effect is overshadowed by 3G.
Put another way, you will NEVER get battery life much longer than a day if you're on 3g, so you're wasting your energy trying all kinds of tricks.

For me the widget did nothing. But it seems like it's not even supposed to turn the 3G radio off, but ALL APN network traffic. Did I miss something? It won't save battery power as long as the 3G radio is on.
I went back to the 2G-3G OnOff widget by Curvefish. It's not one-click, it's just a shortcut to Mobile Network Settings, but it works. Note that sometimes it takes a while for the data connection to re-establish after you see the 3G or E icon.

While i understand the idea behind this thread, your conclusion is simple.
If you use the phone as a smartphone, it will eat up your battery no matter what.
I personally go through two batteries and some a day. (they cost about 12 bucks in ebay, and they work just fine)
The price for saving battery is not using the phone, and having a 400 bucks phone just for show off is just silly at least.
If you have a phone like this is to use it. At least you can change the battery not like some other devices......

I understand that task killer is useless, but do any of you use Autokiller (memory manager) ?

That's kind of a redundant question because even if you do not use the app, your phone is still performing the functions. The app just adjusts the settings. But to answer your question, using a memory optimization tool such as AutoKiller is 1000% more efficient than using a Task Killer. I don't think it effects battery much, but works wonders on performance.

There's no 3g-off widget because apparently in Android there's no way to do that through a direct command. I also use the Curvefish widget, and you are absolutely right about turning off 3g to save battery. I normally do so when I'm asleep or if I'm sitting at my desk next to a computer (why do I need fast data on my phone when I have my computer right here?).
The other thing I would recommend is AutoStarts. There are way too many apps that open themselves up at bizarre and inappropriate times. Autostarts is an easy and painless way to see which apps do this and keep them from opening.

Great battery life comes to people who hardly use their phones. Guess I need to get a netbook. Will prolly get a netbook or 3g laptop + skype and ETF my phone soon. These battery woes are show-stopping.

Losing 4% an hour on standby when you're not using the phone is unacceptable. Samsung screwed something up with the JI6 update. Most people think it's because of the stupid Media Hub. I think they are right.
People are not complaining about the poor battery life from using the phone. They are complaining about the slow battery drain even when they are not using it. ~4% an hour adds up fast. Vibrant is supposed to have 450 hour (18 days) stand-by time. That's what is rated. But people are getting 24 hour (1 day) stand-by time after JI6.

I'm not ready to sign off on this idea. For me simply flashing JI2 over JI6 fixed it. For some people flashing JI6 back over still left the problem fixed. I still have those processes running on JI2 and my battery life is fine.
The other reason I'm not ready to recommend wiping out those DRM processes is that apparently it stops the bundled Avatar movie from playing, and might affect other things that users may get pissed about. I've read that killing the downloader process people are talking about kills the market. So I really wish those people advocating that solution would figure their **** out and provide exact steps for the fix (right now their posts are really vague like "kill the processes that are named something like this" and not well tested; in all my research I didn't find the exact name of the "downloader" process).

Is it possible to flash the ji2 modem without root? Wishful thinking, I suppose..

[Q] Is this normal battery use?

After 8.5 hrs of sleep I woke up to only 77% battery and when I went to bed it was at 100%... so with ZERO use of the phone it dropped 23%.. seems like a lot to me but is this normal for everyone? I'm running DJ05, Superclean .7, the stable version of geekniks kernel..

If I don't set airplane mode when I go to sleep at night, after 8 hours I will have lost anywhere from 20-30% of my battery. I have terrible coverage at my place, so that is the reason that is causing it. It's not nearly as bad if I turn off sync, but still drops >10%. In airplane mode though, I lost 2-3% over 8 hours last night.

I'm having the same problem, even at work if I take my phone off at full charge and just let it sit, 3hrs later its down 20%. and that's with me not touching it. I'm running the same thing

I turn auto-sync off at night and go to bed with 97% and wake up with 94%. I had battery issues with the xda app before though SEE HERE. No one else seems to have noticed this and it even contiued into DJ05. Might be something to look into or you might discover what is killing you.
good day.

Wipe the battery stats after flashing a kernel or rom. But before you do that, charge the phone to 100%. After wiping battery stats, disconnect the charger and use the phone regularly and let it die out. Then charge it back to 100%, not turning it on. This is a battery calibration, and I always do this after flashing a kernel. I've had instances where I've had the battery go down 1% during the night after doing this.
Rockin' DJ05, Minimal Icognito, Clocked at 1.3Ghz

Eh, it's a bit surprising that display took up 40% while your phone was supposedly asleep; maybe something woke it up during the night and turned the screen on.

That's about what I get over night, but i'm using a not using a custom kernel.

try a different kernel
after trying every kernel available, ive ended up with jt's 11/29 kernel being the absolute best on battery life. im getting around 30 hours with normal use, all other kernels seem to last 12-14 on my phone.

I turned off auto sync and only lost 10%.. So that helped, I also just installed a new kernel so we well see how that runs too..

Sent from my SCH-I500 using XDA App

One improvement I have noticed in the battery is it cut off about 1/3 of the time to get a charge.. In about 2 hours I went from 23% to 85% (with the phone running) and there is no way I would have been able to do that when I was running DI01.. IDK if it has anything to do with with the ROM, Kernel, or the fact that I'm on DJ05 but ever since I updated my charge time was cut by 1/3..

Hi there,
as you can see at the screenshot, there is about 3 to 6 Percent CPU Activity, no Device usage and the Battery drained from 100 down to 70% over night. I tried it with
1)Battery Doc (cycle charge)
2)Delete the battery history, and did this
1.Turn your device ON and Charge the device for 8 hours or more
2.Unplug the device and Turn the phone OFF and charge for 1 hour
3.Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for one hour
it looks like that this is normal, right ?
Thanks for your help

what is your time without service? Settings > About Phone > Battery Use > Cell Standby

Thx for the quick response, it is 37%. "Witout service" means, the phone tries to find a signal, or some kind of "sleep mode" ?

It means that it's trying to find a signal. The more it tries to find a signal, the more the battery drains. Try putting it into airplane mode at night, probably will only have a few % lost on the battery then.

Actually it won't matter if you use a custom rom or kernel, smartphone these days will lose battery like crazy if you use heavy net data. I have DX and Droid2, they are the same way with froyo.
Also in case those of who didn't know, whenever you flash a rom, you automatically wipe your battery stats and others.
You definitely shouldn't wipe battery stats when you are on the midway. You should wipe either at nearly dying or completely full. However, wiping battery only "recalibrates," it does not increase the actual battery juice.

Different ROMs/kernels can help you minimize the battery drain as much as possible though by limiting how much is used by the cpu or background apps accessing the net.

Actually no. Different roms have all the same basic data usage, basic google auto-sync. Roms can't control what or how much data will be used by an app. Kernels also can't control how much net data will be utilized. Kernels can shutoff apps based on complier/lowmemkiller fix but that is based on the memory status, not net data usage.

What is the app's name for the battery usage percentage?

Warning to those with battery drain on freex10

I was getting really fantastic battery life until today when I installed dolphin hd. I'm not sure why, but the moment I installed that, my battery could literally be watched dropping, even when it wasn't open. Once I got rid of it, my battery life then went right back to being great as it was before. The odd thing is, under battery usage, it wasn't showing up when it wasn't running, yet as it was the only change I made, and the sole factor in the change in battery life, I'm positive that's what it was. I'm curious how many people experiencing bad battery drain are using this browser.

i am using dolphin mini and dont think i have battery problem.
maybe you should try it.

I have all these and my battery life is fine, I don't think you get what I said at all. I think dolphin could be the cause of so many people having battery troubles, as once I installed it I started experiencing the same things they said, and then once I uninstalled it the problem was gone. I am back to about 1% an hour drop hen in standby, however with the dolphin installed (even when it wasn't running and I wasn't connected to wifi or 3g) I was dropping about 5-10% just in standby per hour.

Hmm.... might remove it and see if I can see a difference.. but my battery life isn't even horrible. A little worse than before maybe. But I'm getting a solid 10 hours at least.

freex10 severe Battery drain with latest X10i official SE update.
Running Beta 4 after factory SE updated yesterday on my X10i. I have severe battery drain. 89% after loading the freex10 beta4 with apps zip install and a TI restore of all my prior progs. Left the phone plugged in and charging overnight and this morning it was 4%. I am not using any special browsers. I am using Advanced Task Killer and killed all the programs before leaving the phone. Any ideas??

I really wish there was a way to dual boot with xrecovery.. that way we could use stock SE during the day because it has better battery life, and when we are near a charger we can use 2.2

I had the battery drain problem where I was losing 5 - 10% per hour after upgrading to beta 4. While I cannot prove it I think the drain is related to the baseband upgrade and how it interacts with 3g on AT&T. I can't turn off data as this is my work e-mail device. After some experimentation I found that switching to 2g "fixed" the problem. I took my phone off the charger 4 hours ago and with moderate e-mail use, 1 30 minute phone call and some XDA and web browsing I am at 91%. I added the 2g/3g to the power control widget and can quickly switch to 3g when I want/need the additional speed.
One other unintended benefit I found from 2G. For some reason my phone will not drop in certain areas where I drop calls every time I am on 3g.

Possibly due to wifi?
Ok guys so I re-did the OE factory SE update and re-did the xrecovery to redo freex10 beta4. all went well but I was to sleepy to setup the wifi. This morning my phone was fully charged and ready to go. I came into work and turned the wifi on to use on our network. Phones been on standby and wifi is set to be off with the display. Its only been 3 hours and my phone is at 10%. Why is wifi drawing so much power even when not in use?

So far I saw many causes in 2.2, check my list here
> Dolphin HD (from this OP? - unconfirmed)
> Stock Email get partial wakelock with exchange server.
> Dialer - partial wakelock (you might not feel it, but it is, compared to 2.1)
> Dialer - drainage when turn 'turn to silence' on (Call setting)
For Dolphin, well as I trusted in android system, I believe there might be something else 'between' dolphin and the battery, I don't think it's the dolphin itself. Since it doesn't report anywhere between spareparts or battery usage, or even CPU usage. I must admit that 2.1 is doing better in term of 'system stability' (not about hanging, crashing - but to handle when something go wrong)
I also must admit that using ATK in 2.2 is likely cause trouble, I used to have battery trouble and there was no way out before I turned to ATK. well, thing got 'weird' (it was not worse) If you feel something wrong, 3G trouble, some stupid force close, try disable ATK.

I never used ATK in the fresh install. Posibly the stock E-mail however I haven't set that up either. Its a shame as the rom is real good and appears stable other than the battery drain issue. I've already tried the Xrecovery wipe of battery stats, cache, etc with no luck. I may just stick with the factory SE rom till freex10 is no longer a beta..

gotta give this a try
it's been driving me crazy wondering why my batter drains so fast

Worth a shot for sure! I get 24 hours easily with heavy usage... It's a lot better for me than beta 3 was

I use to have bad battery issues with this rom but then I install juice defender and it has done wonders for me. Task killers help but nothing like this app does.
Sent from my X10i using XDA App

I'm using beta 3 with constant 3g and dolphin hd. No problems. Batt drain is as usual with 2.1 original. I get about 1-1.5 days of usage, sometimes even 2.

[Q] mikg 1.03 battery issues

This is by far my favorite Rom yet but I'm having battery issues that I haven't had before. I unplugged my phone last night at 100% and when i woke up 5 hours later my battery was at 68% normally it would only drop about 10% or less in 5 hours. any ideas? I have all new radios and wimax and such.

Is your phone sleeping?
Sent from my PC36100 using XDA App

Once we get a new custom kernel, it should remedy the battery issues on that ROM.
We just have to wait for HTC to release the source for the latest kernel.

OK stupid question how do I know if my phone is sleeping ?

At 7am I reset battery stats and put in a 100% battery (charged on an external charger)
Now (11:15) I am at 69% I expect this to get better once the batt stats are done.
I have new radios and the kernel for the ROM.

stock battery. i dont think my phone is sleeping.

If you have mobile data on, your battery will drain a lot faster, especially while we're all stuck with the stock kernel

No battery problems here. Altho it is the stock Kernel, i can easily use my phone for a full day with several calls, a bit of gaming and youtube (3G) while in the pooper and have 50-60% remaining in the evening
Try to reduce app sync frequency (you don't need that when in bed really..), LED notifications
No juice defender, or taskiller, or extended battery- just using setCPU with "onDemand" governor

That's about where mine is, too. I'm used to my SBC setup though, where I'd be at 85% by the end of the day.

You should not be losing that much battery over night. I generally only lose 2-3%. Have you checked your battery usage? Post a screen shot of it.
It looks like this
http://smartphoneblogging.com/wp-co...ngerbread_battery_consumption_app_graphic.png
You can see when your phone is awake vs screen off. And if you click on the apps in the list, it will tell you how long that app kept the phone awake,

So when can we expect a custom kernel. i use set cpu with ondemand also no juice defender or app killers here either.

Try it w/o latitude on. I only drop 1-2 maybe 3% through the night once i turned those off. I have my facebook contacts set to sync once a day (don't really need more than that unless you add friends a lot or they update their picture frequently)
Weather I have set to 3 hours, but there is an option to update on device wake..so that isn't an issue either.
Give it a try and see if it helps.
Also if you haven't calibrated your battery, charge your phone to 100%, boot to recovery and wipe battery stats, drain battery til phone shuts off and then charge phone back to 100%. I can usually get about 24 hours of moderate use out of my phone.

ok will try those. i did battery wipe just yesterday

just click the link in my signature for some really good battery tips

OK guys so nothing I done helped my battery life while sleeping so I wiped wiped and wiped again and reflashed twice set everything back up and now my phone sleeps again. These roms can be funny like that sometimes I guess. Any thoughts on that?
Sent from my PC36100 using XDA Premium App

Roms, especially ones that are ports, can be weird like that sometimes. If a couple of wipes and a re-flash did the trick then I'd say that's great.
If not, then it's just bad luck I guess. Hopefully the kernel source will come out in the next few weeks and we'll be able to get kernels that can squeeze out better battery life.

Terrible atrix battery

I've unlocked and am running Ken's Alien ROM and so far I really like this. Im an international user on orange uk, so I use faux123's kernel for Oc and ram fix. But there is one caveat. I have really rubbish battery life. I did all the stuff (charge to 100% from 0% wipe stats, calibrate). The fact is, I left it on, for ten hours. The display was on for about 2. No usage. When I returned the battery was 30%, with phone idle consuming 30%. Newer radio needed? What can I do? My baseband is N_01.95.00R .
I've heard good things about the newest AT&T radio for battery. How can I flash this to an international ATRIX?
Help appreciated

Edit : phone idle consumed 40% :O

I have the exact same issue. Unfortunately, all that I can say is that changing neither kernel, radio or rom did fix this issue. I had some improvements when I followed this topic and flashed back my stock kernel (with no OC), but still very far from what I would consider a decent battery lifetime (10h with 3g + email and twitter sync and screen off)
Some users have tried and it worked well from them. I'm on the team that didn't work ): But you could give it a shot

Calibrate your battery. Charge to 100% wipe battery stats. Then discharge to shut off. Then charge to 100% again.

OP stated he tried calibration without success... I too am having subpar battery performance - interested to see what others have done to achieve better battery performance besides the previously mentioned methods.

I've done all that stuff, but it doesn't help IMHO. (at least it didn't do anything for me)
Only 2 real fixes that have worked for me are these:
1. Freeze unnecessarily apps with Titanium Backup (use "System panel" from the Market to find out what keeps constantly running/popping up in the background that you don't need)
AND
2. Turn off Automatic Sync, and get in the habit of doing that stuff manually all at once.
@2. I use to sync in the worst signal areas, and that drained the **** out of my battery. Sync/get your updates manually in strong signal areas whenever possible...

New radio from the fruitcakes thread and the latest faux123 kernel seemed to kill that bug.
I sold my atrix to my less then nerdy friend and I just fixed that bug for him yesterday. Same deal tho...

I noticed from X2 battery (I think) every minute or two the phone constantly checks for either cell or data signal. I can let my iphone 4 sit on the counter all day and it might use 1-2% but my atrix drops 5% in an hour without touching it. No calibration or battery fix will help. Even CM7 uses it fairly quickly. Im running Alien 4 with max battery saver and gps and auto sync disabled...it should last for a full day with heavy usage.

Alien 4 w/theme, faux123 kernel, everything at stock settings for this rom, nothing frozen, and I am sitting at 1 day and 13 hours with 28% left, mostly idle, but an hour long call and bit of game playing.
If you are getting something on the order of just a few hours then your phone or battery must be bad. I am doing nothing to extend the battery life other then using the default settings.

The phone should get 2 days sitting on the counter..LOL Of all the phones I've had and iPhones I've jailbroken, there is definately something wrong with the Motorola or Android software running on this phone. I've never had to worry about calibrating or battery fixes. This is just my honest opinion. I've had 2 ROMs in all the ones I've flashed that had good battery life and I think it was a coincedence that maybe something didn't load right or got deleted by accident.

Most iphone users need to charge at LEAST once a day. A lot of them charge more than once. I can sometimes get 2 days usage from my Atrix, with heavy texting, some calls, and some games - which is pretty damn good.
Maybe your battery is the issue. not all Atrix are created equal and not all batteries function the same

When you go into settings>running apps, does your free and used ram add up to over 800? Mine used to and now it doesn't. It adds up to like 750....I always thought it would add up to mid to upper 800's. It also could be the battery but I was pointing out that I have left my wife's Iphone 4 and my atrix on the counter all day (neither one got used) and my atrix was down in the 70% range and her phone was at 96%. I'm just thinking something is running or consuming the battery. I've used fastboot to do all wipes and still seem to be having an issue.... I also flash ROMs every few days so maybe the battery calibration doesn't have time to really calibrate. I'll pick a combo I like and keeep it for a few days and see if I notice a better battery life.

How long has it been since you've flashed a ROM? It usually takes a few days for it to settle back in and provide decent battery life (at least from my experience). My phone right now has been on for a little over 7 hours and is at about 55% with Display using up 60% of the battery (3hrs on). This is with the Alien v4 and Faux's latest kernel. The first few days after flashing a ROM my phone would usually only last about 7 hours.

i get 2-3 days on stand by. and about 6-8 hours of straight use. 3-5 if i'm using mobile broadband.
1: keep gps and data off (background data is almost irrelevant.)
2: use green power
3: use a task manager to close applications that you are not using. (be sure you can add "ignore" exceptions otherwise get a different manager. anyone who says not to use a task manager is a ****ing punk hipster ***** fag who's irreparable damage to the geeks good name will not go unpunished)
4: do the "wipe battery stats" bit after every flash (100% charge, wipe stats, full discharge)
5: is to install a custom kernel and use SetCPU to underclock to 312 while the screen is off..
most importantly: use your head. if you stream 1080p using mobile broadband for 2 hours your battery is dead.

I flash ROMs every few days but I call BS on the whole "Battery Calibration" thing. If my battery is showing 4200mv...it's full. It will die faster the more processes the phone does so my point it....whether I flash a rom every day it shouldn't matter, if the phone (After I set up and install whetever apps) gets unplugged, something drains the battery. Maybe the infra red sensor is always on, or a process is always starting and ending, who knows but the battery cannot be calibrated, the phone might need to be calibrated to read the correct voltage but batteries don't hold memory unlike the old NiCD rechargables from years ago.

When you flash a rom the battery stats get messed up. Based on what I know the way the battery drains depends on previous battery usage data hence the reason why it last longer after a few days of use after a rom is flashed. It needs to build up new data to correctly report battery use. Maybe I'm wrong but my experience supports this.

I am running Alien v4 with the stock kernel and I am getting well over a day with pretty heavy usage (phone calls, texts, emails, FB, twitter, XDA, Games). My setup:
Battery Mode= Maximum Battery Savings
Auto Brightness off, usually on 30%
Unused blur apps frozen
Reinstalled performancemanager.apk (blur task manager), set to kill unnecessary apps after 2 minutes of inactivity
No overclock, I don't see the need to overclock outside of high benchmark scores. Without overclock I still play every game smoothly without any hickups or slow downs. The phone still feels super fast without it.
I turn off all unused services (gps, bluetooth, wifi)

After you charge your phone and take it off the charger, reboot it.
It seems that a process kills the phones battery after you take it off the charger. You have to reboot after taking it off. It works wonders. Currently on 16 hours of use @ 45% battery on alien rom with stock kernel.
Cheers.

I use the same battery settings recently. I turn off GPS and Sync unless I'm using navigation. Which blur apps do you freeze? I just noticed (read on the Alien thread) On the unlock screen, hold the home button and it unlocks. I wonder if something like in pocket detection keeps the IR eye on all the time.
