Hey, im on Telus so i dont have any other modes I can switch to to lower the drain. Ive noticed my battery drain is HORRENDOUS
Over the past 4 hours ive dropped 60%!
Now im wondering if im just running too many apps or if my stock battery may not be holding a proper charge anymore, and wanted to compare with others to see if others are running the same amount of apps and getting better battery or what
Ive got the following on:
Trillian (IM app)
K9-mail checking 2 aps
Regular Sync (Twitter, FB, Dropbox, Google(Calendar, Gmail, Contacts)
The battery usage summary seems to lie, 35% is the screen but only 13 minutes. Yet im at 40%
Android System at 20, Cell standby 13, Phone Idle 8
While heading to work, i ran DI Radio(music streaming), and lost 20% over around 35 minutes.
Im using the Tuesday rom with it's default kernel.
Is there anything I can do for better battery, because I dont have wifi in most places, and im running 3-4 bars constantly yet the phone just drains rentelessly. Even my Mugen battery was only lasting 16 hours...
It's quite possible that it's the ROM. I used to always get 8 hours on a single charge, regardless of location or ROM. I'm running Eugene's CM7 and I'm getting 13 hours on the same typical usage.
I'm running on Telus as well, with no wifi at all.
Although I am not running all of your apps, I would still consider myself a moderate to heavy user.

Seems rather sad that the phone can only do 8 hours on a charge. Im going to restore my juggernaut and see how that compares i guess.

Yeah, I know how you feel. Just experiment other ROMs and see if you get any changes.
How much usage would you get out of juggernaut?

Its been a while since ive run juggernaut. But it used to only drain 10% an hour i believe on 4g. I've restored my nandroid of Jugg and will be monitoring that.

any syncing or usage of the network will take a drain. any usage.
you can always turn on airplane mode and let it sit a few hours and see the drain, that determines whether its network or a ROM/kernel drain.
But yes, using 4G has big battery cost
Battery Life
I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.
I'm at hour 8 today on Darkside Digital Warfare, and 70% free from 8am to 4:30pm. I have push corporate email, automatic brightness, friendcaster push, and a slew of accounts and it runs like a champ with amazing battery.
Make sure your phone is going into Deep Sleep as often as possible when screen is off. My phone seems to be extremely picky in regards to which charger it likes and more often than not (even had this happen on the stock charger) the phone refuses to sleep after being charged (even if only for a few seconds...).
Download CPUSpy from the market and after each charge, go to CPUSpy, press menu and Reset Totals (phone cannot enter Deep Sleep during charging so it's important you start fresh after a charge to get accurate sleep time). Turn the screen off for a minute or two and turn it back on. Press menu again and Refresh Totals. In my experience, if the phone is not sleeping at this point - Deep Sleep showing in Unused States - then it will not sleep all day and remain in 384Mhz for hours, killing the battery rather quickly. From then, if I plug the phone in a supported charger (even for a second) and disconnect, Deep Sleep resumes normally. Rebooting always fixes it too.
If, like me, a lot of people also have this problem with the stock charger as well, I bet many are dissatisfied with the battery performance... The phone is supposed to spend the majority of it's time in Deep Sleep. I get this issue with several different chargers and cables and on different ROMS / kernels (including stock... go figure).
Im pretty sure its the signal itself draining it. It uses sleep for at least 40% of the time its on. I use my phone a good amount, but its the fact that if it sits on 4g even with the screen of, its rapidly draining during this time. ive even reset timers and left it sitting for an hour and itll be in sleep but lose 8% over an hour just doing nothing. I still wanna be able to recieve notifications tho so turning off data isnt an option. I will test turning off data anyways to see if the drain stops.
The battery drain is all those persistent internet apps running. That is what you call heavy usage. Trillian and the FB app being the two biggest. Music streaming would be up there as well if you aren't in good signal area. Look at your battery stats and see what your signal strength is.

Im getting some weird battery stuff, as well as the Android OS drain. If I restart my phone, once in a while It drops like 20-30%. i'll go from 46% to like 18%. I see the threads about slow draining, but mine seems to happen instantly sometimes (3 different times so far in a week), anyone have solutions? Got it from someone on ebay, can I still/should I RMA?
Someone posted a kernel fix in the international GSII forum, so we're either waiting for that to get ported over here or wait for samsung to release a fix. I have that same bug too. What percent r u getting on the Android OS? Mine is usually in the 60's.
Yeah I saw that thread, and I saw the 2 things causing it. Waiting for that fix I guess, hopefully it solves the big battery drops as well as the small draining. Mines pretty high, 30-50% I believe, and then cell reception takes 10-20% with LOS
That's alot better than mine. Although, I don't have that LOS problem. I'm running stock atm. Are u on a custom rom?
Running Starburst 1.5, stock was better for no LOS. But I like the customization on Starburst. Hopefully by the end of this week the kernel we be ported over.
Most likely a problem with the battery level algo and not an actual battery charge drop. It's probably showing the correct value after the reboot.
Using battery spy I was using like 12%-15% per hour, not even doing anything. Saw online that formating the SD card might help, just did, and now im using .8% per hour. The hell, something was scanning the SD card or something. Much better now, hopefully itll last 10-20 hours instead of 6 hours.
edit: so it went back up again. At .8% it will last 2 days+, but since the events keep taking the CPU, its draining it. I got it down to 4-8% by taking the SD card out. At least it will last a little longer. Cant wait for the fix, this baby will last days after.
Damn that sucks. I just formatted my card too cuz I was running out of options. Keep us updated tho.
so I think media scanner is draining, I downloaded rescan media root from android market and before I was draining at 12% per hour, but when I disable it with the app, it goes down to 5-6%. Anyone else try? Maybe thats something thats draining.
Oh btw have u tried turning off wifi? It only drained 6% after being off the charger for 9 hours. I havent touched the phone during that time span tho. Android os still in the 50s btw.

this is almost definitely correct. battery doesn't drop 15-20% because of reboot...the reading is wrong. Battery drivers have been bad on a few of the latest android phones. Just look at when your phone stays at 99% for the first 3 hrs of use each day...what, does it just get really inefficient in the afternoon because of food coma from lunch?

Trying now, seems to be charging faster too. I was mainly on wifi because cell standby was really high, keep getting LOS. But maybe I wont with wifi off now, and i'll see how battery does. ill keep you updated.
Still bad. Can only wait for the patches/fixes. 8 hours doing nothing almost. Sigh.

Hey man, I got one more tweak for u to try. I just rooted my phone w/ the latest zenomax kernel and Starburst 1.5. Download setcpu and create a profile for "screen off". Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Think I have the v3 version and 1.5 as well. I have setcpu set to 200-400 powersave. ive tried others and same. Suspend and events/0 keeping eating at the CPU. Thanks for the suggestions though.
figured i'd chime in here. i've had days where the battery was fine and days where the battery was absolute trash. it's happened on stock, and it's happened on root. but it almost always seems to coincide with LOS. the first picture is one of several instances where i've had pretty fast drain followed up by an instant dump in charge under normal use. it's strange how after the drop, it slowly works back up then levels off and drains normally. the 2nd pic is from today. i left my phone at home on accident when i went off to work, and when i returned, i had LOS and this battery stat. you can tell where i lost signal . the last pic is from yesterday while i had the phone at work all day and light use; a nice consistent drain.
FU battery drops and FML
Ok so i read all the posts in this thread and i understand theres a issue that effects the phone from even knowing what the battery % is. i had to post these though. i was at 47% then rebooted my phone. phone boots up and yehhh! woop woop 8% now mind you if you look at the graph it shows a nice constant cerve downward but steady because i was using my phone the entire time. now after the restart/batery drop of 40% i kept using the phone constantly but its funny how it took me over a hour of screen on to go from 8% to 5% !!!!! i bet to get from 5% to 1% it will take 2 more hours for sure. you can see the graph start to flatten out like its a super battery after the 40% drop because it didnt really drop to 8% !!! normally i wouldnt care since my phone battery last just as long, it just goes down really slow from 8%-1% but at 5% it auto dims screen and wont let me use my camera for the next 2-3 hours while i knock off the remaining "4%" of battery left. fml
Get Starburst v1.6. He removed DRM processes which should lower Android OS usage and thus battery draining. Plus with the LoStKernel, I haven't had any issues with losing signal since.
Also, use Titanium backup to remove running services that you don't need. I got rid of the stock email client, digital clock, media/social hub if you don't use those. They don't take up a lot of ram, but every little bit helps.
My battery life has improved after battery calibration. I suggest you calibrate if you didn't already so your battery usage graph may be more accurate. Hope this helps.
Thanks for the tips! I was wondering how you would calibrate the battery. Is it the same as wiping battery stats from CWM?
I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.
Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?
Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.
Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.
I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel
From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.
Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise
Currently using latest calk rom I get about 2 hours using my phone for browsing thr internet at home. When 3g is turned on it drains even faster.
It has always been like this. If the phone is set on idle without 3g and wifi it lasts about 10 hours.
also it takes about 3 to 4 hours to fully charge, i feel this is too long.
so any rom that might help me? is the battery faulty?

Blazer ROM
why are you using your phone to browse all day long ? use a pc or a tablet. its a phone not a desktop pc. plus put it into airplane mode and then turn wifi on, it disables the cel/data radios hence the battery last longer. If your phone takes 3-4 hours to charge from 0-100 something is wrong with it. turn if off and charge it, cuts down charging time A LOT !
That is ridiculous. But I've been using Blazer Rom for about 2 weeks now and I always get 30 hours+ battery life. I just got 3.8 and I hit over 40 hours just this weekend.
well, um, wow, those are some ... great suggestions...
you might have a bad batt, sure.
i would think it is likely something else though.
a few things off the top of my head.
is this on a "clean install"?
is there some app you have loaded that might be pinging/updating constantly? (I'm on the exact same rom, getting all day at least)
what modem are you on?
did you flash a custom kernel?
do you know how to take a screenshot of battery usage? show us what processes are eating it?

It could be a bad ROM (bad install, not the ROM itself), but don't presume that's the case.
Measuring whether the phone is draining appropriately is difficult to do when it's in active use (e.g., 2 hours of browsing) ; thus most people measure effective drain by measuring the drain rate when the phone is 'sleeping' -- though in some cases a bad app or bad install will prevent the phone from sleeping.
I would recommend charging the phone to full, leave all default radios on (GPS/Wifi/3g), and let it sit for an hour or two. If you're losing more than ~3-5%/hour, then you have a problem.
Tools you can use:
- CPU Spy - Will show you whether your phone is entering Sleep state or not
- Battery Monitor Widget Pro - will measure your mA drain rate; during sleep, you'd want it to be at least below 20mA, ideally below 10mA (note, this app requires a couple of charge/discharge cycles before its measurements are reliable).
- Better Battery Stats -- If you find your device is NOT sleeping, this will help you figure out what applications (including the kernel) may be preventing the device from sleeping.

Your point? I could kill my phone in 6 hours too, but why would I want to do that? I play games all the time when I'm out at work or just out in general and I still get over 24 hours of battery. I never use my phone when I'm at home, that's what I have my tv and computer for.
how long has it been since you flashed? Maybe it needs a few cycles to settle. Do you have any wake lock issues? get betterbatterystats app, free for xda members, to check for kernel or partial wake locks.
I'm on BlazerROM 3.7 and getting about 1% every 2 hours on idle. It took me a week to see the battery life i'm getting now. My wife is on calks 2.8.1, I don't know what shes getting but when she gets home from work, she's still around 50%. On stock, she was typically around 30% already.
how do you get betterbatterystats for free as an xda member?
I'm on blazers and i'm at 79% battery at the 7hr mark on battery.

I have seen this "mystery battery drain" problem in other threads. There is usually an app responsible. Try Watchdog, its not bad.
I also have heard that SD card or file errors can be responsible for the drain. Formatting the memory takes care of the problem. If it were me, I would format the memory, then run chkdsk (Windoze, or the equivalent in another OS) to mark bad sectors. In the case of internal memory, you will have to do that through the USB cable. Do so at your own risk, of course

The point is you walk into someones situation and act as if their usage of the device on whatever rom your on is going to produce a parallel experience. One of the biggest factors no matter the rom is screen brightness. If you spend most of your time out doors the experience is completely different even with the same usage patterns otherwise. I love screen brightness personally, haptic feedback is nice too who cares about the battery when the experience is better?
I have games on the phone, GTA III, MC2/3, Dead Space, etc. I don't actually play them. I remote into my PC, browser the web. I have a TON of apps that use the phone idle/background. I keep steam and im+ pro going. I let TEP ping GPS data every 10 minutes. Weather widget, google voice, etc. I even have Samsung Apps installed with its oh so horrible push service that apparently rapes peoples batteries... cant say it hurts at all.
Today was a day for me where my boss was around so I couldn't use the device much and when i did it meant leaving things like a remote client on because I couldn't touch it to turn it off. 52% battery was left after 12 hours so it obviously was going to survive the 16 hours I am awake, going to sleep now so it would easily last 24 hours. But the battery being Li-Ion and me actually caring about it, its going on the charger. Tomorrow could be 30 and the next day will probably be 8 hours.
As far as the topic is progressing. Check your apps and your settings. Ive had battery life so bad the phone died on the charger. Same rom, same apps slightly different setup later and I am getting good to acceptable and that constant wake this guy is probably getting is gone.
If your using a lot of push apps, you're battery becomes nothing more than a decoration, lol. Apps like aim, kik, basically all the chat ones. Games like words with friends. The more apps you have checking for updates on top of heavy usage with kill your battery fairly efficiently

Which personally was part of the issue before on my setup. I still have them going again and battery life is decent. I mean Id want 16 hours out of a phone surely whatever my day is Ill have it on a charger by bed time.
I personally usually get 12 hours or more on days Im not using it constantly, 6 to 8 if I am using it every waking second. 24+ on days off. Haven't tried blazer in particular myself yet but Calks seems manageable even for demanding use.

I have tried radio 0312 and 1111 (http://forum.xda-developers.com/showthread.php?t=1134451)
I have tried aeroevan's v10 and v10.5 kernel (http://goo.im/devs/aeroevan/kernel/vivow/)
My battery life is pretty low. At max I can get about 4 hours of usage, throughout the day.
It looses about 20% in a 6 hour sleeping period (deep sleep not working?)
ideas?
thank you.

Well,... I got amazing battery life on Aerovan's kernel v9. I never tried the newer kernels. And I get pretty good battery life with the TSM UKB ROM too. I think I am on radio 1111... Hmm.
If I don't use my phone I have 84% at the end of the day. CDMA on (not in airplane mode), wifi on.

What are you synching during the day and at what intervals? Governor and Min Max Speeds? Do you live/work in a crappy signal area? Use a lot of bluetooth or wifi?
I uninstalled facebook and twitter and whatever else asks you for your first born child permission wise, and stopped Maps from starting at basically five or six different system-wide events.
Purchase Autostarts from market and see what is running during each system wide event.

everything is stock in terms of intervals, and governor, and cpu speeds.
I travel all over, so my signal strength goes up and and down. But I think you may have hit the problem.
Before flashing (stock) I pretty much always had 4-5 bars wherever. After flashing (s-off, root, etc), I have never had above 2 bars.
Using my home as an example, I normally had 5 bars of service. Now looking at my phone, I have 1.
Internet speeds are fine (250kb/s down 87kb/s up). Phone call quality is the same.
My signal Strength in front of my computer is -77dbm. Outside my front door is -102dbm.
I wasn't getting the battery life i was, so i did flash v9 and i'm back at 1% battery loss while phone is unused. I wasn't getting that with v10 or v 10.5. I could barely get a day between charge. I should get 2 days with v9 because i did before.

You can try other radios. I understand some have better effects than others with each handset.
Also, I tend to update PRL and such before installing a new ROM using a stock ROM.
I have already tried the two recommended radios. The funny part is 0322 was the radio my phone had before I hacked it.
after flashing each rom you have to program and that updates the PRL anyways.
But just to be sure i did the roaming capabilities, and no change.
Ill try v9 of the kernel. anything else?
Do you have the Facebook app installed?

As Condemned said...it isnt necessary. But I live in a fringe area where PRL may prove useful so I do this.
May not be the answer your looking for but try an extended battery. I bought one a week and a half ago for $5.20 from amazon. Its the 2150 mah. And this sucker lasts all day. Using kangdemnation 0.3 with stock aokp kernel oc to 1.5ghz. 13hrs later and at 59% with low usage for 6hrs (work) moderate for an hr and heavy for 3hrs and then back to low for the rest of the time.

Na, the phone was fine on battery before the hack, from past experiences it's always been even better after. Maybe I'll restock and see if that helps.
Yeah Facebook has been performing poorly on many people's phones especially while on 3g. Sometimes loading very slowly and sometimes not at all. It has also been causing a wake lock problem which I personally experienced that wakes your phone while it should be asleep (not the screen just the os.) That causes battery life to be poor for many users.
I hear that FriendCaster is much better if you want an app to replace the app! Or some are using the mobile site if they don't care about notifications. Personally I just uninstalled Facebook after I started having problems and haven't been on Facebook since.
Try uninstalling the app and see if that helps. It nearly doubled my battery life when I did.

*Edit* I almost forgot, I did read somewhere that stock roms like andybonestock have fewer problems with Facebook. Also, I read that Facebook has acknowledged the problems, confirmed its on their end, and are currently working on it.

If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors, and re-calibrating the battery along with these steps may help, may not. But, worth a try anyhow:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM (if installed) or use Rom Manager (is device is supported).
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

I also support FriendCaster. The facebook app hardly worked when I used it. The only time it half worked was when I was home and on wifi. I actually like what FriendCaster...I like what it does with the layout and I feel it's a lot more intuitive then the official app anyway. Plus for some reason facebook had become a datahog. This could be OPs problem in terms of battery drainage because Im pretty sure they download a lot in the background.
Currently running Jedi x11, and have had if for about a week now in order to test if there are infact major improvements.
I never really sat down with a timer and timed how long it took my phone to deplete, or charge, so I won't have an exact time duration for these, but I can confidently say, that since I got Jedi x11 on here, two things have started to happen.
1) Battery takes a very extended time in recharging. Both when in use, and set aside. - Previously, my battery would fully charge anywhere from 1 1/2 - 2 hours from about 15%.
2) My battery is depleting ridiculously fast. I type fairly fast, I'd say about avarage, and just for an example, I started this thread at 93%, and at this very moment, it's now at 91%... Even when not in use, the battery seems to deplete at a much faster rate. Tethering is also very draining now. - Previously, again, never timed it, but I am sure by the constant use of my phone that I've had for some time now, that this wasn't ever the case before.
This is just my observations: It would seem Jedi helps when the phone isn't in use. I'm not sure if this mentioned CPU sleeper helps with that or not, it's hard to tell as like I said, the battery goes down even when no major screen time is in use. Maybe it's something I have to turn on? Maybe not. Another, observation, when I am actively using the phone the battery will drop fast. Like, double fast.
And lastly, I observe the battery life will stay on a certain percentage longer than it does others. (Currently 89%) I took about 10 - 15 minutes writing this.
Any thoughts? Thanks for any replies I do get.

I'm glad I'm not the only one with this problem on this rom. Phone takes 9 hrs to fully charge, I was starting to think I'm going crazy. My battery will charge fast if I go back to stock. But I would hate to go back because of this.

Well guys, I'm not sure what's going on, but, it should be noted. The Battery on this thing just lasted the entire evening from last night (7pm) up until now, with about the same amount of use that I did the days before when I noticed abnormal battery depletion.
Currently at 47% and I've yet to charge the phone. Of course that is with the fact that I put the phone in airplane mode while I sleep for a few hours. I watched a lot of video, listened to audio, and it's as if they thing knew I wasn't pleased with what was happening, it's now behaving like it should.
This happened a few days ago also, where the battery lasted 16 hours and was at 27%. So this leads me to think it's something that happens on and off, and I have no clue what triggers it. phone ussage rains the same. Took about 5-7 minutes writing this, and the battery marker only went from 47%, to 46%.
Credit where it's due.

a lot of factors involved when it comes to battery. based on my experience, try to see what's going on with your system using this thread. noted post 1-3. also investigate about your kernel. i am using perseus kernel and my charging time is pretty good improving than on stock :good:. also i can undervolt CPU.
where you at and which service provide you use, again, have impact on this case. i used to be with t-mo and now trying h2o (att mvno) and my battery is dropping faster when i use data. i believe since at&t coverage is suck where i am at, specially when indoors, thus phone radio has to work extra harder to get reception and shorten battery's life.

In the early days of Android CPUs were not very efficient. Undervolting helped battery life. That is no longer the case. Most good kernel devs will tell you they hate under clocking because it has a placebo effect and makes their kernel unstable.

thanks ronnie. it's good to know. wondering why some of them (well known, i believe) still offering CPU voltage adjustment (up & down) if they see it inefficient ? is it because the kernel still in beta thus come with tweak utility ?
Yeah, there is definitely something awkward going on. I took my phone out of airplane mode this morning and started viewing FB for a couple minutes; a battery that was at 98% is now somehow at 92%. It's definitely on and off. I wasn't even watching any videos or anything like that.
Would all the apps that are in ram be sucking juices this badly? I had to terminate a lot of em just a minute ago. Or, is this thing somehow giving me a false charge reading? Battery seemed to charge faster than usual last night.
I'm not even fully certain the devs read these question forums at times.
I'm runnng the international XXDMB6 based ROM on mine and currently, I'm at 76% with only an hour and 3 minutes of screentime?
I don't use Wi-Fi.
My LTE signal is rather poor.
My screen generally stays around 50% but it's on auto.
Of course I let my apps sync. But that's pretty much just gmail and facebook.
I have my weather set to sync once every hour.
I uninstalled the apps that are pretty much bloat (flipfonts, the hubs, the samsung live wallpapers, musicFX since I use DPSManager, Samsung's music app and that's all I can think of)
I'm running Perseus's kernel with about 200-350mV undervolts.
Is it truly the poor LTE signal that's taking such a toll on my battery life? I used to average 5-5.5 hours before my battery dies. Now I'm betting I'll only get around 4. When I had Verizon, the power draw from LTE was unnoticeable from 3G. Is it really that different on GSM phones?

Battery life is very noticable with lte. Reason being that volte doesnt exsist yet so two or more radios jeed to be active at the same time.
Im suprised you couldnt tell a difference on verizon, it was night and day for me.

I found Battery Drain Analyzer helpful. I kept it running for a couple of months and was able to determine which apps consume the most power (widgets, by far). But, after having spent hours trying different underclocking configurations without success, I ended up buying three extra batteries. It's really awesome to not have to worry about it. I just keep them in my pocket and swap them out as needed. It's not a very technologically advanced solution, but, it sure is effective. I use this Charger for the spares. It takes a long time to charge the batteries, but charges them fully to 100%, whereas, charging the battery in the phone doesn't seem to work as well.
