Is this normal battery usage? It seems a little low. How's yours compared to mine? I'm on Eaglesblood 2.3.5 with Faux's kernel. I cleared battery stats at 100% after I installed the ROM. Also any tips to decrease battery usage would be helpful. Besides the ordinary turn down the brightness crap haha. Im using autokiller memory optimizer, could that affect it much?

Is probably the nightly that this 2.3.5 is based on, i believe is one of the 90. The 100+ got some pretty good battery life.

Everything I've ever read about Android says that those memory optimizer/task killers actually make your battery drain more quickly rather than making it last longer.
G2X CM7
It looks like you're using the phone for long periods of time every time the phone is on. Watching tv episodes or navigating w/ the GPS maybe (with high brightness)? If so, your battery life is probably just fine.
It's easier to gauge battery life when nothing is going on, eg screen off. That way you could use Betterbatterystats to monitor wakelocks to see which things are keeping your phone awake when the screen is off.
I know one big battery gobbler is latitude.
Well mem optimizer is different. Except its hard to set up for yourself correctly, so not worth the minimal gaain BC chances are you're doing it wrong. No offense. I tried it for a few days and couldn't get it right
And ya, I'd say that's pretty bad. Check mine out, ESP the screen on time and percentage
Wont let me upload.. whatever. Ive hhad 10hrs of data on and 5 of wifi, 2.5 of screen ON and I'm sitting around 66%, So multiply that by three for a complete drain.

Thanks everyone! I just decided to go with the latest nightly. I set up memory optimizer up right i think it was worked fairly well actually (usually i had more than 200mb of free RAM) I also hit the auto task killer widget alot cause im like ocd about things running. Will hitting that alot drain battery? Also Im thinking about starting a thread where you charge up your phone for exactly 30 minutes while the screen is off and take a screenshot. It might be interesting to check out charge up times on different ROMs/kernels but I'm not sure if they would differ or not? You guys think I should do it?
Every time you kill tasks they re just starting up again

Correct. Task killers waste more battery because your phone ends up running more CPU cycles to restart the tasks you killed that didn't need to be.
G2X CM7
If i kill all the tasks and wait a second and go back into advanced task killer and uncheck all the ones that started back up again would that be more productive?
My best experience in saving battery has been done by:
1. Turn the lights off when you're not using them!
(GSP, WiFi, & Data control via power control widget)
2. Underclock CPU when phone is on standby or below 30-50%
(Using faux123 & SetCPU profiles)
3. Turn off any sync that isn't needed. Avoid Push. If you ever do need syncs (for mail or social media) tell it to update at selected intervals, I usually have mine between 1-4 hours.
As for killing apps, I usually use the "long-press to kill app" option in CM7 ROMS to close out of apps when I'm done using them. Otherwise a quick visit to the "running processes" to make sure nothing to battery/data intensive is running will usually do the trick.
But you shouldn't want to kill every running task, most don't take up a noticeable amount of battery life. Just be mindful of FB, Games, Cameras, or data intensive apps.
On a normal day I will use WiFi to download a few apps or files, use GPS for directions, and Data network for MMS or other and still get through a full day with 60-70% battery life on my G2x.

Hey guys,
Just wanted to share a few things I stumbled upon recently. The first thing we usually notice is really crappy battery life when we flash a new rom. I tried using a bunch of stuff like juice defender etc. I recently used the MIUI rom and then came back to dexters 1.3. Anyways this time I used a small app called Battery Calibration. Basically what it does is delete the batterystats.bin which is generated by each ROM. Charge till hundred, use the app and then discharge completely once. Then recharge the second time. I noticed a 200% increase in battery life on dexters. I dont use my phone alot but this was with around 1 hour talk, 2-3 hrs one and off browsing, 30-40 texts, a few photo's etc. It lasted 1 d 14 hrs when usually itd last around 20 hours. So you guys can give it a try.
Another thing, juice defender works by toggling the data connection. Now I use Edge as mobile data and wifi at home. I realized my battery lasts as long as if not more than with juice defender. Ive come up with a theory, that apps which disable the connection takes more juice because with every screen on the radio has to search for the network, wifi signal and then connect to it. Leaving my data on all the time, or wifi on all the time does nothing at all to the battery in the idle state. It only uses juice when there is data transfer. I left my wifi on all day with autosync off and it cost me 2% juice. Anyways give these tips a try. Worked for me well.
Calibrate your batteries after each flash and dont use any third party monitoring apps. And set your wifi to sleep with the screen, tell me how it works out for you!

I use both those actually 3rdstring turned me on the to Battery Calibrator, but I purchased the Juice Defender Plus b/c it has the ability to customize its toggle for each individual app. Enable, Enable/screen off (good for online music or something like that b/c your screen eats battery and is chief in temperature hikes), Disable or Do Nothing. Their is a Juice Defender Ultimate, but has a lot of things that XT720 doesn't use or need like 4g toggle and stuff like that.
The makers of Juice Defender have another app called Juice Plotter that shows you battery use. Was useful for a week or so but it is another service that is running in the background all the time so I uninstalled it.
There is a nice monitor app that I have had since day one called Battstats and it is a simple widget that has a low memory footprint when running in the background but it show the charge %, Volts (4.2 +/- is full charge) and temperature (c/f). Small 1x1 widget so it doesn't eat a whole lot of memory and I have found that it is fairly accurate.
One last thing is if you are overclocking, make sure that it is set right or you will eat more battery than it is worth, not too mention stability issues. If you set the vsels too low, the phone will reboot now and then on its own. If you set it too high, then it eats unnecessary battery. I have mine at 1100/ 74 and is totally stable. Volts might be a little high, but it works for me. Depends on what you want though b/c overclocking makes you phone faster but kills battery power. Underclocking slows things down but uses less battery. SetCPU can set up profiles for this.

You need to discharge it once completely till it turns off itself. Did you do that? First charge till 100, then use the calibration, then discharge completely doing your normal stuff. Then completely recharge Im sure youll notice a change. I did

Hey 3rdstring. I had my setcpu settings like that before I stopped using it. The reason was when you set it low at screen off and you get a call it lags real bad. Like when you are trying to accept the call by swiping the lock to the right its lagging, even the ringer skips abit. I also noticed with the cpu set low to 250 the phone has trouble finding antennae and signals. I've seen no increase in battery life with either set cpu or juice defender. Does this happen to you?

Lol, sorry it isnt working for you guys. One thing though when it completely discharges it takes a lil time for it to have enough juice to turn on. So it not like the battery got screwed on anything. Im still getting a battery life of 1.5 days when before It was extremely bad like 20 hours.
So I'm like wtf all of a sudden my battery is like at 40% by noon, and I recharge and it gets to the same within a couple of hours }
I don't get it not even a year yet
BTW I'm stock froyo/ rooted
Bad battery ? Any one else experience this? I have juice defender set CPU
Battery stats say main cause is "cell standby" any tricks to fix this?
No I'm not going to gb
meh...
Well, in the end, that's the best that froyo can do for the G2X...
I had Froyo and i pulled off 6hrs, when i got GB i was able to pull off 8, so yea, juice defender really wouldn't give you that much more battery life, the best shot is to upgrade the ROM.
i would consider updating it :/ i've never had froyo but since i've been using gb i get 15+ hours out of my phone and that's with heavy texting, internet browsing, some netflix watching and a little gaming. but cell standby seems to be my biggest problem too i wish i could fix that

Usually bad battery life can be accredited to less-than-optimal user settings, heavy device usage, or there's a rogue app that's sucking your battery down.

Hey OP, can you post a list of your apps? Use listables. I want to compare it against mine. If there are any similar apps then I'm going to disable/uninstall mine and check battery life and report back.
Have you tried booting into recovery and erasing battery data? That greatly improved battery life on my Nexus S after it had undergone multiple ROM flashes.

The ROM you're using is a huge matter. With CM7, i couldn't go a day without charging. Now, with MIUI, I'm pretty sure I can get 3 days, with normal brightness, and my normal use, which is email and texting.

Oh really? I'm getting slightly less battery now than I ever have on any ohter custom ROM, and I don't think it's because ICS is less efficient.
I don't think my phone is sleeping properly, as I'm losing about 3% an hour with my phone off, nothing going on except for the usual google syncs, which i've always had on on any rom.
Total I'm getting about 12-13 hours, and it's not my display topping off usage, but android OS. My keep awake times seem pretty ridiculous given that they're always greater than the culmunative time spent out of deepsleep (according to cpu spy)
which kernel are you guys using?

I doubt it, the battery life is a good 5-7 hours less than GB with the same usage. the android OS is definitely preventing it from sleeping properly. GB would barely loose 5-7% during an idle of about 7-8 hours, now i loose close to 20%+
I've been using oICS v43 and Steve's Awesome Sauce kernel (aosp linked it from here: http://forum.xda-developers.com/show...64221&page=503). I was able to get 17hrs of battery with medium-heavy use (Netflix, Droid TV Prime Time, Browsing, File Downloading, Texting, Couple Calls, and Wifi Always On). If I let it run without using it, I'm looking at 60+ hrs of battery life.
I'm trying Matrix v14 right now. Will let you know results.
Tested it with cpu spy, cleared all timers and left my phone 10 hours over night. On settings the os was on top but cpu spy said my phone was in deep idle 9.5h of 10. I got updates for weather every hour and a bad wireless signal so that COULD take 30 min of awake considering it also have to get my location.
Im soooo trusting cpu spy over the standard battery history so I also belive it could be a log problem instead of a real awake bug.

I do agree with you. Similar behaviour with my NS. That Android OS consumption even higher than my Screen, yet I still manage to clocked 24-30h with my moderate usage.
* I use full ROM instead of Update one.
I'm not sure if people are not using their phones, but I'm already at half battery life and I just unplugged less than 5 hours ago. I'm on eugene's kernel and tried Matrix's as well, both haven't help along with the oICSv43. I've been closing out my programs after I opened them too. I just bought the phone/battery off ebay, the battery is a samsung and it was in a sealed plastic bag, so it should be brand new, but I could be wrong.
I'm almost ready to go back to stock.
You dont have to be a genious to seal a plastic bag. If the seller was ebay trusted then it should be good and you should look somewhere else. For me for ex, low brightness using loggraph improves battery more than any kernel.

I never heard of these roms, I'm on Sprint.
With My Xoom, when I had honeycomb installed with Airplane Mode enabled I could easily leave the Xoom on my counter for a couple of weeks and I would still have a 20-30% of battery power.
Since I installed the EOS Nightly ICS build the tablet eats up 30% of battery power after only 4 hours even on Airplane mode.
Something is definitely amiss here.

Sorry, got to disagree with you there. With wifi never asleep, overnight my phone drained 5% in 10 hours. This is about double what i got with gingerbread. I never use deep idle, which is more for people who use their phones with the screen off, e.g. listening to music, downloading torrents.

you are probably a heavy user. I charge my phone (on average) every 2 days.
Not sure what ROM or kernel you're running, but I'm running the latest "Team Acid" version of AOKP with latest kernel it comes with and I have no problems with my battery. Of course I that's just with normal use (texting, calling, viewing xda via app, gtalk and some web browsing). My battery usually still has any where between 30% and 50% by night time when i place on my dock for the night to charge. Time of use is from 5 am to about 9 pm.
The way I use my phone, I was lucky to get through from 6 A.M. to 6 P.M. without having to charge with GB and the AntonX kernel. My life was comparable using the stock TeamAcid AOKP ICS ROM and kernel. Undervolting an additional 75 mV, allowing overclocking to 1200 MHz, and using the smartassv2 governor I seem to be able to get through the day, but definitely need to plug in in the evening if I didn't charge during the day.
The biggest run-time improvement for me was a new battery. Even the 1500 mAh Samsung battery I got as a spare was significantly better than my 18-month-old 1650 mAh Samsung that came with my phone.
Better Battery Stats is an indispensable app for gathering information in understanding why your battery life may not be as good as it could be. Looking at the ICS monitor of data usage (or My Data Manager, which will run on GB as well) can provide good insights as well. By watching the output of those, removing/freezing some apps that I don't need that wakelock the phone, setting "quiet hours," turning off WiFI at night, and not dropping to "2G/GSM" for background data transfer, I am typically around 90% charge after ~8 hours of "really idle" overnight. It is a couple percent lower if it is a night that Titanium Backup runs a scheduled backup.
I would get around 15 hours of fairly heavy use. I was running barebones with antonx oc/uv kernel I was undervolted and using the 2300 mah battery

My battery life is unrealistic. This is most the reason I post roms and share them with you. I cannot gauge how well a rom will behave until more "use cases" exercise the phone's abilities.
For one, I don't have t-mobile anymore, so the RIL doesn't behave the way it does on your phone (when you are on t-mobile), because I only get edge. I don't use this phone as my daily driver, so I don't pack the phone up with a bunch of applications or multimedia (videos, mp3s, etc...).
With that my phone gets really great battery life.
Right now my 'herring r7' rom (to be released soon) has me at 3h 16m on battery @ 97%. I'm sure the time will continue to go up and battery usage will slowly decay. I really won't know how it will act until I release it and wait for you guys to respond.
I hope that gives you a little view into why I can't always gauge how a rom is going to act and why it is so important that I get feedback.
Thanks guys bug I'm running the latest Team Acid CM9 with Hefe's kernel and battery life is just terrible, my battery lasts about 4 hrs at 96%. Not sure if its my battery that needs replacing but anyone have suggestions on improving battery life?

I got "better battery stats" from the market.
The developer has a thread somewhere here on xda.
It is a great tool for figuring out what is running so often that is eating your battery.
With that, I've found that doing a factory reset, wiping everything (including my sdcard, after backing it up... of course), makes sure nothing residual is around to make applications go wacky. I don't use TB or any other tools to restore backed up apps. I either do it manually with adb or just reinstall stuff from the market. I never restore data.
Where can I find your new rom when its ready

Battery life means nothing without listing display time. My SGS4G is currently at 5 days. However when I actually used it as my daily phone I would get about 4 hours display over the course of a normal day. 3½ display time if I used it for much gaming or YouTube streaming.

It all depends. Playing HD youtube over 4G with brightness turned up full and checking email every 2 mins, etc is going to kill it a lot faster than data/wifi turned off, screen at the lowest brightness and sitting in your pocket without the screen on. There is no test benchmark to test ROM's for this, because even things like how far you are away from the router, if you're connected B/G/N could all effect the battery life, so it's hard to get a standard test. Here is an average day for me though.
This is Remics, no real tweaks, smartass2 governor running. Few hours of music, pedometer tracking in the background to track walking for an hour or so, bit of surfing, instagram pic taking and uploading, editing for an 30 mins oror so, installed 3 other camera last night and rebooting and playing around, lots of suduko, hour or so of youtube, lots of txting, ummm, tested a wifi calling apps that worked good for about 30mins, I can't remember what else over the past 26hours and still 26% left.

I'm lucky to get 6 hours.
something that ive been always been wondering..
every time i get a new phone i seem to have bad luck with them when it comes to battery..(optimus 4x, nexus 4, nexus 5) i always see reviews and comments saying they get X screen on time and i always get X-2 screen on time and poor standby time
ive tried everything, changing roms, kernels, checking wakelocks turning wifi or 3g off when not used(LTE always off)
the most i ever seem to get is 3 hours and thats a really good day on low performance(underclocked) and i also barely game..
how in the hell do people get 5 hours screen time and complain about it.. meaning that they actually get more! and they say they game and browse alot.. im not only comparing to people online, i also compare with my friends who get good battery.. we dont seem to be doing anything different
does anyone know the problem/solution to this?!
I really recommend to go on stock firmware and DON'T install/restore any of ur apps.
Then see what's up.
CHEERS
It's all about looking at what is using your battery and mitigating as many of them as you can. Some people might find they can't live without many features of a phone and so will generally get less time then someone who is willing to sacrifice certain features or adjust their usage to improve battery time.
Sharing your full setup could help us help you... ROM, kernel and kernel settings, apps installed, tweaks made, wakelocks you're having, etc.
Personally, I'm coming to the N5 from the Verizon Galaxy Nexus, and I've been astounded with the battery life of this phone. It's the first time in over a year, that I don't feel the burning need to carry a charger with me everywhere I go. Additionally, this is the first device that's made me seriously consider NOT rooting.
As of this moment, I'm running rooted stock firmware, with Faux kernel 008m, and I'm getting spectacular results! I'd love to help you work this out.
As a point of comparison, this is a battery life readout I took two days ago... I can't complain at all about nearly 27 hours of uptime, with 4 hours SOT.

This is on T-Mobile LTE the entire time, GPS on, moderate usage, and only useless apps (for me at least) frozen, including the GEL launcher, the stock news app, Google Earth, the stock email app, and the non-English keyboards...that's it.

ive tried almost every rom-kernel combination there could possibly be all resulting the same.. my stock had OK-ish battery life but still not great
im on 100% now charging so theres nothing to upload and my wakelocks show nothing just maps.. and i forgot to mention that i usually turn off location as well.. i have no problem changing to stock but most people get good battery life with roms too..i dont mind which kernel either cause every kernel will be really fast with the snapdragon 800
current rom liquid smooth
kernel - just upgraded to faux an hour ago.. phone is heating and percentage dropping fast(not that the previous ones were great)
no tweaks
kernel settings
fast fast charge, eco mode and intelliplug- all on
300000-2265600 frequency

I recommend do this on a stock ROM, but can work on any.
Have your phone set up normally. Charge it full, reboot in "safe mode" and don't open any apps. Just let it do its thing for a few hours, or over night. See how the battery life is now. It should improve. If so, you got something 3rd party killing it.
Turn off location reporting and location history. It'll improve your battery life dramatically without making any noticeable impact on the phone's capabilities (including Google Now). I also recommend disabling Google+ if you don't use it.
^Great suggestion!
@namnam123 did you have heat issues with the phone, prior to flashing Liquid or Faux? From my Galaxy Nexus days, I remember heat problems being caused (occasionally) by an improper/nonexistent wipe during flashing. You cleared dalvik and cache at least, correct?

The point is to see if the battery still drains as quickly without any third-party apps or mods. If not, then the problem isn't the phone, but rather something you installed on it. Some apps can run in the background and drain battery power even when you're not using them. Some mods like custom kernels can also worsen battery life.

yes i always wipe the cache and dalvik cache
Make sure wifi scanning is off too. And ages ago usb fast charge used to cause issues with massive battery drain when the screen was on. So turn it off and see if it helps. I am talking years ago tho. It was literally meant to be turned on when plugging in and leaving the phone alone. Then disabled when taking off charge
Also post some screen shots of your battery stats
