My battery has been depleting at a very rapid rate and am wondering if it's normal or something I can do on my end to fix. For example, I made a phone call and left a voicemail and the battery went down about 3%. I was thinking of just buying a replacement battery, but if there is something I can do to try and fix the current one, I'm open to that.
Thanks!

Depending on your reception (and length of call/voicemail), that could be quite normal. There are other factors as well; is this a new phone? Have you recently flashed a new ROM, restored a backup or done a factory reset?

I just checked my phone since I posted the initial thread and it went down another 8%?! It definitely didn't used to be like this. The phone isn't new, it's about 14 months old. And yes I did recently root my phone and flash CM7 on it, but I thought it would have improved the battery life, not make it worse!
Let me know if any other info is needed, thanks!
Using the phone in the same location (like work or home) as you previously used the phone? Reception is often tied to location. I get rapid battery drain when in poor reception areas.
How long ago did you flash the ROM? You should cycle the battery from full charged (100%) to about 20% (but not empty) and repeat this a couple times in order to properly calibrate the battery meter. This needs to be done every time you flash a new ROM, in order for battery readings to be accurate. You can also clear the battery stats before you do this, to make sure any previous data is not screwing up the calibration.

As redpoint stated, you need to cycle a few times after flashing a new ROM.
Let's say your battery was at 60% when you flashed CM, the ROM is basically going to think that 60% is as full as it gets; after a few cycles, the ROM will "learn" your battery.
Additionally, there are so many tweaks one can do with CM that you can actually kill you battery faster if you max everything out (overclock all the way, turn on all the eyecandy, etc.)

Check your parameters, set OC profiles in order to optimize energy consumption, also as said upper calibrate battery meter and then see how your battery holds, i don't think it's a physical defection because hardware is well made but you never know so do this and then we'll see.
download battery monitor widget from market and track the history and usage statistics, that will give you a starting point to trace the issue. as a reference, my DZ running miui and cm7 kernel is using roughly 26-29 mah with screen off

I'd suggest flashing a new kernel for better battery life if all else fails.
Currently I'm running EliteMod's kernel, U flash it just like you would a rom
http://forum.xda-developers.com/showthread.php?t=1246682
I've been getting some bad battery life but not nearly as bad as you have.
I suggest fiddling with SetCPU or turning off all your usual wireless services like Wi-Fi, 3G and GPS
I bet the problem is that you got sync on! That NAILS AND KILLS BATTERY FAST!
Here you new gameplan.
Step 1: Download battery dr.
Step 2: Shut off all sync (manually sync when you need email updates etc.)
Step 3: buy 2 backup batteries from Ebay for cheap
Step 4: Shut off volume vibrate on keypress, shut off all animations, shut off volume noise on keypress, turn screen of from inactivity to 15 seconds.
That should help. Let me know your results.

Some advice I can shed on this is having Wifi on all the time, (by all the time you mean at least 24/7), that could be a strong point why your battery life is low. Another thing is the number of apps that require data being pulled running in the background
1. Having Wifi on for the time you state is bad if you don't have a signal. Reason why is that since there is no signal for your Wifi to obtain it will continue to search and fail, search and fail which actually drains some good amount of battery being forced to repeat such a task unlike when having a steady signal it's usage becomes minimal
2. High number of data pulling apps also works the same except then have the option to change the time they pull data which can be usually found under settings/options tab
Try these out and let us know how it goes =]

Hmmmmm
I barely noticed that you are running a custom rom. After flashing the new rom did you wipe battery stats? If not, that can actually affect battery life as all roms run differently and different data is applied to the battery stat
There are two ways to go about wiping the stats. You can boot into recovery and Wipe Dalvik Cache under the advanced settings or you can download Battery Calibration from the marketplace which in my experience is a lot easier
Battery Calibration
The instructions are inside the app on how to implement the process
I had this rom for a while but when I flashed it, I did not wipe data or anything. I decided to wipe data to give it a try and reflashed it. I charged it completely and calibrated it. I am in the process of running the battery until it dies so I can recharge it to complete the calibration process.

DO NOT drain the battery until it dies!!! Just down to 15-20%, then charge to full, repeat a couple times. Over-discharge is not good for Li ion batteries.
People on here keep recommending it, or saying they do it. Its NOT a good idea, and proliferating this bad advice needs to stop. Draining the battery to dead is bad for the life of the battery. Also over-discharge can possibly render the battery unable to take a charge, requiring you to buy a new battery. It doesn't happen often, but its happened to a few different people on this phone, and other phones as well.

You seem to know a lot so i'm gonna ask ya redpoint. People say there is a built in safety zone so even when the battery is reporting as 0 it really isn't. The batteries do not allow themselves to get below a certain threshold for the reason you are explaining. Is this not true? Lots of people who know nothing of xda or cell phones in general let there phone run the whole way out for whatever reason. I would think that cell/battery manufacturers would take that into consideration.
the reason people used to tell you to drain the battery complete was based on an older battery tech that has what you would call a "memory" it needs to "memorize" it's lowest and highest point in order to calibrate the battery. Li-ions do not need that. They actually keep track of your charge cycles.
suppose it can handle 1000 cycles. on the first day, you used up 75% of your battery and put it on the charger to max. then the next day you use another 75% and do the same thing. at this point what actually happens is that the battery will count this as 1.5 cycles rather than 2 cycles. But redpoint is right.
Do NOT drain the battery completely when it's a Li-ion battery. it's old advice for old tech battery that is legit for that type of battery but not Li-ion batteries.
To calibrate your battery, you just use your phone normally. It will figure out where it is supposed to be as you use and charge it over the course of a few days.
better battery life

It is true that there is a built in 'safety zone' so that the battery does not drain completely to zero.
However, it is also true that this 'safety zone' can and HAS failed for some users (including some who are on these forums)
With the way that Li-Ion batteries work, and 'calibrate', there is no added benefit to draining it completely to zero. If there is no benefit, then the risk is not worth it.

These ideas ran through my mind reading your post:
I. You might want to calibrate your battery. I've run into many instruction how to do this (just google the keywords: Desire Z calibrate battery), but basically the ones that do NOT require you to drain your battery to zero first, came down to this:
0. Turn Fastboot OFF!
1. Power on your Desire then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ... power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.
Many people seem to have greatly increased their battery life just by following those simple steps. I am currently in the process of trying it myself, but will probably need some hours before I can verify if the overall life has significantly increased.
II. You might want to install an App like "Watchdog lite" for a longterm check if you have any apps or processes, that work as a battery eater in the background.
III. if the above tips should fail, you might want to upgrade your radio and maybe also align the radio library (RIL), to match it best with your radio and ROM. But do a lot of reading and research before actually performing that task, since this is nothing for beginners and might even make things worse. This thread might be a good point to start your research.
hope that helps,

Got a Desire Z, but the battery seems to go down too fast, even when not in use. Same thing when the phone is off also.
I get around 5-7 hours of the phone being on with about 15mins use and the battery is dead.
When the phone is off, I get about 8 hours.
I know its not the battery as I've tried a few. Ive also tried a few ROMs aswel as stock ROMs.
Any ideas on how I could fix this?
Thanks

Every time you flash a new ROM you're wiping the battery stats and it takes the OS a few days to re-learn your battery. Wipe the stats manually and give it a few days.

Around 3 days.

x2 this happens a lot especially going from ROM to ROM. The built in function works ok, but I generally use Android booster to narrow down errant specific apps even built in Android apps like sync. It helped me go from 15 or so hours to 24+ especially if you use autostarts and TB to freeze or prevent from startup
3 ish days is probably not enough for Android to learn the battery levels properly. It takes a few charge cycles to get the values right. I wouldn't have thought its good to wipe battery stats constantly.
With the Touch Pro 2, you could force a learn by discharging it completely until it doesn't power on the firmware any more, pull the battery for a minute, charge overnight while powered off, pull the battery again for a minute then power on. This updates the values in the firmware too.
I have read it works with the Desire Z too, and I've tried it after a ROM flash just to wipe. Obviously, while you can still get into recovery, wipe battery stats prior to this.
Disclaimer: Do this once only, its very bad for Li-ion batteries to repeat this. Do this at your own risk.
If that don't work:
If it does it in airplane mode then its probably an app.
Make sure you flash something like a rooted stock ROM and make doubly sure you wipe everything before first boot. Data / Cache / Dalvic cache etc.
If you haven't installed any apps and it still does it, RMA the phone for repair / replacement.
Hope that helps!

Thanks for all the help above. Will try for a few more
Days.
Though the battery even dies when the phone is off.
Well, Ive still got the same problem. Ive realised aswel, when the battery dies and I go to charge it up the orange led flashes for around 5-10 minutes and then turns a solid orange.
Same thing happens with a replacement battery.
Im guessing its probably a hardware fault

I've had the orange led flashing before after a completely flat battery. Its probably something to do with a dangerously low voltage from the battery. Its extremely bad for Li batteries to get very low..

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.

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.

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.

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.

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.

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.
After using the original Note, I decided I couldn't live with the battery life and decided to upgrade to the Note 2 last christmas. I was fully satisfied, and frequently got between 6 to 7h of screen time.
Sadly, since early june, I barely get half of that under normal usage (2-3 hours), and I've never been able to go a day without charging the phone. The phone is rooted but still on Rogers Canada's original firmware with the original Samsung battery.
I'm no novice to android, but I've run out of ideas. Is it normal for a battery to start loosing it's capacity after around 120 to 150 charging cycles?
1) I thought it might be related to my external microsd, because I started getting error messages that I was disconnecting, and the mediascanner process was running for an abnormally long time. I wiped the card, and the errors persisted. Finally, I removed it altogether and the mediascanner battery drain stoppped, but overall battery life didn't get any better
2) I comptetelly wiped the phone and started from scratch, reinstalling everything from the market. No change.
3) I've been checking per app battery usage with BetterBatteryStats, and I occasionnally get one misbehaving app that keeps the phone awake, so I installed Greenify to prevent a few of them from gobbling up resources. That's helped a lot, at least on BetterBatteryStats, but still the phone doesn't last longer. There is no more obviously abnormal app anymore.
4) I tough it might be related to the fact that I redirected all my work email to gmail, so I set it to manual mode, but it hasn't helped.
5) I did notice that the cpu stays either in deep sleep or at 1,1 ghz, almost without using the other speeds. I don't know that I can do anything about that with the stock kernel.
Is there something else I could be checking? The phone worked great for six months without gooing through all of that stuff, so the only thing I can think of is a hardware issue. Did I get a faulty battery?
Thanks for your insights.
Nothing lasts forever; buy a new battery
hmmm the 1.1ghz thing makes it seem like it could be a deeper issue, there is no reason it should be sticking at a frequency that high.. I would personally try to flash the stock rom fresh with odin.
That would be your issue, the high frequency, not the battery itself imo

I notice thst on mine im loosing juice quick when my LTE radio is on and I'm in poor coverage area. Switching to 4g/3g/2g only helps a lot. On day when I take few pics my battery takes a hit because all pictures backup performed by dropbox etc

I will start out by saying I have ALMOST tried every trick or hack or mod software related to attempt and resolve this issue.
I will let the screenshots speak for themselves.
I am starting to think there is something physically wrong with this device which is odd because when I opened it up to take the plastic cover off to expose the boards I found no evidence of any liquid intrusion at all.
Only one of the pictures is from a different charge cycle maybe a day or two after the others.
To be specific I am trying to eliminate deep sleep battery drain as much as possible. my htc one x does not drain anywhere near what this galaxy s3 does even though everything is disabled. I've tried different rom / kernel / settings / screen / leds / sync / etc.
Wondering if someone might notice something I've missed here.
thanks!

It could be app updates. There was an update to Google drive just a couple days ago and that night after I updated it my battery died overnight when it was nearly fully charged. I cleared the app cache and data and the phone is back to normal. I've seen this happen with a few app updates lately.
Hope this helps.
It could be, and quite possibly is something like what jack man said above. But it could also have to do with the battery itself getting old. Many of these devices have been running for over 2 years now, and the batteries do go bad.
If you really think its a hardware issue though, the only way to know for sure is to flash stock firmware via Odin, factory reset with stock recovery (wipes ALL your apos and data), then test it out over a couple of full cycles without restoring any old data. If you are running anything custom, or restoring backup data, you have way to many "unknowns" to make a call on whether or not it has anything to do with hardware.
BBS is great, but unless you use and post its logs (including kernel wakelocks), it won't really tell you much more than you already know and the logs are much more helpful to us than screenshots.
Mine started doing that a couple weeks ago, for like two days the battery drained like crazy even though it was deep sleeping fine with no wake locks, 16% loss per hour ... I replaced the usb cable I was using to charge it, as it was going bad to where you couldn't touch the phone without hearing the connect/disconnect sounds cycling rapidly, bought a ventev 2.1 amp charger to replace the 0.8 I was using, and did a battery recalibration, now all is well, draining less than 1% per hour with screen off, averaging 1.5% during the day with occasional usage. And that's with the stock battery that's been in it for 18mos.

brand new OEM battery from amazon.com - I got the phone stock w/ original battery and noticed the drain issue, first thing I did was order a new battery and flashed CM11 to see what would happen.
drain exists all across the board with this one.
I've also tried different chargers and cables, and even the charging dock on my radio.
what re-calibration method did you use?
I let it run dead till it shut itself off, charged to full while powered off, booted back up and wiped the batterystats.bin, then let it drain all the way again before going back to normal charging cycles.

What is the date on the new oem battery? There are still places with "new" batteries that were actually manufactured 2 years ago. Leaving them shelved for that long they can still go bad. Probably not the caes but figured id mention it anyway.
I will check on that date. I bought an oem samsung charger from bestbuy last night to do a full charge with the phone off. I let it drain down to about 40% from idling and light usage. I've read of people getting better life after using an official charger after several charge cycles.
Ive heard that too. Definitely worth a try, though Ive always thought what matters is the output be the same, but I could be wrong. Never really looked into it.
While trying the new charger for a few cycles you should also set BBS to start monitoring and logging your wakelocks. (Dont forget to tell it to include kernel wakelocks)
This way if you are still having problems youll already have the logs we would end up asking for anyway.
will it save the logs if the phone auto shuts off due to low battery?
I think it should
looks like the logs reset because I have to plug in the phone to get it to boot back up.
either way, the new samsung brand charger doesn't make a bit of difference in terms of battery life, but it does charge the phone a hell of a lot faster haha!
I even did an advance wipe in twrp so I was left with just recovery and download mode so I sideloaded yesterday's CM11 nightly and left it bare with no gapps. also flashed BMS kernel through sideload.
turned everything off (location/wifi) put in airplane mode, and still loosing about 8% an hour with no suspicious wakelocks or "alarms".
what is the difference between the two?

I'm having the same issue.. Pain in the ass.
I've factory reset, clear cache then flashed with Odin the stock 4.4.2 firmwares for Bell, Rogers and Telus, all have the same drain. When I add my google account I get Google play service keep awake issues.
Phone doesn't last 1/2 a day. From 100% it drops about 10%/hour when in airplane mode and 15%/hour is play service is enabled.
I'm blown away by this. The battery isn't the issue, I pulled it and swapped with a known good s3, the drain did not occur on the other s3.
I'd love to get this resolved.. If I can't, on to ebay it goes.
Yeah I'm with you on the eBay thing. At&t maxes trade in at 55 bucks in mint condition. I have to recoup the cost of this new battery from amazon !

Can you get logs of this situation? In your previous case you had an apparent problem with Google Play Services where it would wake your phone up to 32 times per hour. That said, if you still get battery drain like that, after full wipe w/o anything waking your phone up or any wakelock then something is definitely wrong with either your battery or your device.

No BBS = no troubleshooting. From your screenshots one can see you have something keeping your phone awake, but we can't guess what it is.

BetterBatteryStats. It's pretty much the number 1 tool to diagnose battery issues.
