Excessive Battery Drain

My Desire Z has been a battery killer recently. I have tried different radios and roms and it still sucks excessive power. Even on Airplane mode battery monitor widget was giving ~50mah per hour drain with the screen off.
I have both a stock battery and a Mugen 1800ma battery and this seems excessive. I checked and there were no applications keeping the phone awake either. At work with minimal usage my phone easily drains over 30% of the Mugen battery. Signal isn't a problem either because I work 280 metres away from a Bell cell tower and have full signal at work all the time. I'm starting to think that something is wrong with my phone.

I had a similar problem with a stock battery of mine and ended up recalling it with my phone provider and they shipped me a new one. They (T-Mobile) said "not all batteries were created equal" and that sometimes even without water-damage, certain batteries lose their shelf-life much faster than others.
Since you're telling us that both your stock and your after-market are draining at a near equal pace regardless, this might be an indicator that it isn't your battery.
I had to return my original G2 to T-Mobile because of hardware malfunctioning in several areas, namely the audio mechanisms. If you're using a relatively new phone, and/or a refurbished phone, I wouldn't be surprised if you are experiencing similar problems.

Omg, recently, mines been really bad too. Trying to get to the bottom of it.

I'm starting to suspect a hardware problem on mine. I don't overclock at all. I've tried different roms, kernels and radios and it hasn't helped...

I had fast battery drain too, I switched to the ROM in this thread, and battery life is now AMAZING
use SuperWipeG2(+) and Guhl's EFS GPS fix available here before flashing G-lite

Have you tried calibrating? Charging to full, wiping batt stats, discharging/charging back to full uninterrupted? The link below is a great calibration tool.... very convenient. I wipe stats after every ROM flash and keep an eye on CPU/RAM usage with Watchdog lite. Battery life is always good.

how long does the battery last for aprox in standby and with regular use. if it dies faster then 3days on standby or less then a day with regular use there may be an issue im just wanting to know the time span of your battery....
also i had hardware issues with the g2 too. my radio sucked balls, i couldnt even keep signal in a call longer then 3 seconds and my wifi would just cut out for periods of hours at a time... im wondering if the manufacturing is becoming sloppy and they might be lacking quality control. i admit there is a lot to the phone but simple things like battery quality and signal quality should be checked regularly.
with the g2 i frequently hear things like this, battery, screen failures or behind the screen cracks, unresponsive touch screen and black spots, bad radio signals, color leakage and most commonly issues with the keyboard.

Well if battery monitor widget is correct my phone would last 26 hours in airplane mode (36 with my mugen battery) with the screen off (I tested this with almost every user app uninstalled)
Edit:
Considering there was a guy who left his old Hero with CM7 in airplane mode and that it lasted for 30 days before the battery died... I find this quite discouraging

Wow. Battery monitor widget is INCREDIBLY innacurate while in airplane mode. I left my phone in it for a good 10 hours and it was still at 100%

Battery draining way to fast

I let my phone completely die last night because I wanted to get a full charge on this thing. I wake up this morning, and after 4 minutes, it had gone down 4%. It has now been 7, and it's down 7%. Anything I can do?
PS, it is now down to 90%.
Running Calk's rooted FC15 with ics4ics theme and the lockscreen mod.
88% now.

Been on it since Sunday. Location services are not enabled. Yesterday I noticed it had gone down faster than before, battery only lasted just over 8 hours with minimal use, but the wifi kept disconnecting, as did the 3g when wifi was off (this didn't happen in gingerbread).
I wonder if I don't need a new battery. I have noticed battery performance getting worse and worse over the past couple weeks.

I would take your battery and have it checked at Sprint. They will replace it for free if it's bad. My battery gets better after a day or two. I lose 2-3% while asleep on wifi and regularly get 4-6 hours of screen on time depending on how I use my phone. Did you check your wifi sleep policy?

Check what accounts you have setup, and if anything is syncing.
Goggle+, dropbox, and other applications have auto picture sync options which will KILL your battery.
Also location services in google or westher applications, and as always poor signal or no signal.

Yeah, I forgot to mention the sync options. That taxes the battery big time
Sent from my Nexus S 4G using xda premium

Sync is always turned off.
Well, I tried something: pulling the battery for a minute, then when back in, plugging it into the charger. I would give me a false full battery light, because when I unplugged, it showed 90%, and it kept doing this every percentage point, so I kept unplugging and plugging until it showed 100%. Well, 10 minutes have past, and it hasn't budged. So I'm chalking this up to false battery stats.
Thanks for your suggestions!

Yeah, I was going to mention wiping the battery stats but I figured someone would say that does nothing. I always do it when I set up a new ROM even though some do it on install

How many apps do you have installed? Could be a rogue app in backround eating your battery up.
Also with wifi/3g constantly disconnecting also taxes that battery juice faster then a constant steady signal.

FYI, I am having this same problem on the same ROM for the last couple days. I thought I had isolated it to a problem with having USB debugging running when charging from the computer but that's not it either. Last couple days battery is draining so fast that I lose charge while plugged in! Have to charge from wall plug to get an increase in battery. I am having Android OS AND Android System at the top of my battery stats eating 35% and 34% respectively. Clealry not due to syncing or email checks or anything similar as this is the exact same setup I have been running for months (other than the upgrade to Calk's ICS ROM). I'm baffled....

Install these 3 apps:
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
This app will tell you what is holding wake locks on your device. Anything over 30 minutes over the course of a day would be problematic imo. But it depends on what you have installed.
https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy
This will tell you how much time your processor spends at each clock speed. Deep Sleep should be close to 80% with moderate use.
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
This will show you your percent per hour usage of battery. It's optional, but it helps me debug battery use. Typically I run 3-6% per hour with moderate usage.

So it figures, downloaded those apps, rebooted the phone and now its not happening anymore. This has been the problem the last couple days, its intermittent so I keep thinking I've figured out what's wrong and then it happens again. I'm thinking about going back to Gingerbread or trying one of the AOSP roms to see if the problem persists...

I noticed FC15 has the worst battery of all the leaks so far. It a joke shouldn't have even been sent to sprint for testing.

Gonna have to disagree with you there, maybe you have a bad flash. I'm getting an average of 16 hours with fairly heavy usage. FC15 has been fantastic, no issues whatsoever.

Im having kinda the same problem. I just had to get my rooted phone replaced yesterday not that it matters it was rooted I had no roms or nothing on it just rooted at the time, but my battery was fine. I got a white one I havent rooted or nothing yet and battery is going fast. I kept the battery from the previous phone. I was looking through appbrain and seen the app "bad ass battery monitor" and my kernal is killing my battery as of today.

Argghhh Bricked it!
Tried going back to Gingerbread and hard bricked the phone! 5 years on android and four different phones and this is the first time I really truly bricked. Blue led on and not a thing else.
Well I guess getting a new phone is one way to get back to Gingerbread.... For now, I'm sporting a cutting edge Blackberry tour!

Why is this phone so easy to brick? I've had 4 other Android phones and I see more bricked posts for the e4gt than all the others combined...

Before the ICS leaks, this phone was virtually unbrickable. Once we get the ICS source and the recovery issues are sorted out it will be that way again. If you stay clear of wiping individual partitions and follow directions in OP you are safe

Mine has been horrible and have no idea why. I haven't changed apps or anything from previous installs or settings but Android OS loves to eat 50% of my battery which is a good 25% higher than normal.

Guys please help!

Okay, I am having a very frustrating problem that I did not originally have. My phone can last me half the day!! It is very frustrating to have my phone turn off on me everyday at 5 pm ..I love this phone but this is unbearable, especially considering that this is with very, very, very minimal use. If I actually use it the phone intensely, it will drain completely in 1.5 hours. ..It was not this bad a couple of months ago.
I have bullet kernel, and stock GB rom (2.3.5)
I had it always used it on "lag free" setting OC to 1.6 but I changed it to conservative mode to try and see if that would help and it didn't. I even used the core sleeper script from the developer's section and that didn't help either. I had changed radios a number of times when I was tinkering with custom ICS roms. I got my gf this phone a few weeks ago and put the same setup on the phone and she is getting the same battery life. I bought it used.
Does anyone have any suggestions!?? ...I would really appreciate it

You can extend battery life anumber of ways.. Tell me what Is on bt by wifi sync the screen ways ths most energy so turn that down as low a you can... Sounds like you are on an old ROM ...prolly eagles blood?
I suggest digital warfare 2.7 if you are on TMobile. Great battery life. Also flash your radio before your ROM and make sure you are flashing over a clean slate.

I am running on the Stock ROM with android 2.3.5
I am running off a nandroid backup I had restored after having an ICS rom on the phone for a few days. I used darkside superwipe, then flashed radio, then restored the ROM backup.
I always keep GPS, wifi and bluetooth off when I am not using them. I keep wifi on if I know I will be home for the day so I can use that instead of 4G ...I keep my brightness on the lowest setting.
Even with the sleeper core script, turning off 1 core, its still drains out at over 7% per hour without ever even touching the phone. Something is definitely wrong because I read people on the Sleeper Core thread saying they lost 3% in about 6 hours of standby with the script running.
the battery really should be in good condition because the phone is less than 8 months old and I frequently switch between a backup battery (cheap eBay battery), so that should preserve the original a little and even w/o the 2nd battery, the battery shouldn't need replacement this soon.

Have you tried using an app like Badass Battery Monitor to check what's app or process is eating up your battery?
Also, does your spare battery die quickly as well?

No, I haven't used a 3rd party battery monitor app, I just look at the system menu section that tells me what things are using battery and it is says my screen is using 50% ...my spare battery dies very very quickly. But it always has died this quick since the day I bought it because it is a crappy Chinese battery from eBay that I bought for $4 ...the first few times I used it, it would last about half as long as my original samsung battery

You should try to forget about the extra battery... and charge your phone while off then after ten or more mins of it being fully charged unplug then wait and plug back in to charger... It will likely charge again for a minute... Do that little cycle to get a full charge. After i do that i enter CWM and reset batty stats. There is more on this if you google it.

FK23 rapid battery drain

First off I want to say I'm not a noob when it comes to flashing. I usually get 14-18 hours on a full charge with 3-4 hours screen time which seems to be the norm on e4gt roms. I haven't reinstalled any apps since flashing the FK23 stock leak and now a few days into the room settling I have almost 4 hours on a full charge and down to 9 percent left with almost 2 hours screen time. I have checked to see if my battery is swollen and it's not. The battery stops spinning immediately after I let go of it. Screen shots are attached and any insight would definitely be appreciated. I may have to go back to blu kuban since that's been giving me equivalent if not better batter life compared to FK23 stock

I'm having rapid battery drain, too. I used the one-click no-data. I want to wipe everything and start over. Can I simply download and OC the data, or do I need to do something else, first?

As far as I know (devs correct me if I'm wrong) you can just use the OC restore that doesn't say no data... But I went the extra step and copied my entire internal and external to my pc for safe measures and so I could pick and choose what I wanted back on my phone. Then I cleared my internal and external sd before I even one clicked so it was already clean... I just wanted to make 100 percent sure everything was clean but that's just me

Was it completely dead when you put it on charge? I don't know why this works for me, but every Rom I have ever flashed, unless something is wrong with it, gives me better battery life 3-5 days after I flash it. Some of the old-timers say a Rom has to settle for a few days, so maybe it helps do that quicker. If all else fails, reflash the Rom.

I gotta say that your drain seems pretty extreme! I myself am having slightly accelerated battery drain but its better than what I had on ICS. My best recommendation would be to use an app like ROM Toolbox or Titanium Backup to freeze apps and background processes you don't need. If that doesn't help you may need to look at other options.

I'm going to try installing GSAM and checking out what's going on in the background but as far as I can see nothing out of the ordinary is going on with the processes. On a side note when I took a look at my battery itself the sticker has pink X's on it. Not so sure if it's water damage per say but it may be condensation/humidity since I live in Florida. Looking into getting an extended battery as a replacement and any suggestions on the cheapest but most reliable battery to purchase would be helpful and I don't really mind if I have to have a larger back door on my phone. The cheapest I've found is a Trexcell with the back door for $16.99 free shipping. If anyone knows of anything better/cheaper please point me in the right direction.
Another issue I've been having is wifi will connect and reconnect uncontrollably whenever it feels like it, and the sprint connection optimizer was disabled since I Odin'd.

Ya GSAM is a must have. I run it on every one of my devices. I was also getting some irregular battery drain. Then I looked at what apps where keeping my device awake the most and found that hotmail app had a 4 hour wake lock! Ouch! I uninstalled that and setup the default email client to check my hotmail hoping this will resolve my issue. But I can tell you right now nothing else is keeping my device awake that long so in theory this should solve my issue. You may want to go through this same exercise. After a couple of hours of running GSAM looking at which apps are using the most power. Then switch your view to "Time help awake" and see if something has a wake lock holding your device awake.
Good luck

I re-read garwynn's instructions for the one-click and realize that I made a mistake going from ICS (Lightweight) to FK23 without a full wipe. I thought I was paying closer attention when flashing, but I screwed up. Thankfully, this should be easily fixable. I'm running the one-click restore and am optimistic things will be better.

Well after installing gsam I was able to see that after going from 77% to 15% in just over 4 hours with 1 hour screen time I noticed that media server had 293 wakelocks with 1 hour of time held awake...might have found the culprit...will keep you guys updated as im sure it will help a few...just wanted to update that I switched to Universe JB to see if it was just that tar...apparently it wasn't seeing just as much battery drain
Sent from my SPH-D710 using xda premium

And now I also figured out that the media server was not the only culprit. The battery seems to be the problem after numerous tests returning results that the battery was only a 1175 mah battery instead of what it should be 1800 mah. The battery does not spin so don't always judge by that test alone. After deciding to put my OG Epic 4G slider battery in and take it for a spin these are the results I have so far with 300 mah less (1500 total) here is the screen shots below from a full charge
*EDIT * I'm now running blu Kuban FI27 and tested also with the stock 1800mah battery still dies rapidly and WiFi still disconnects and reconnects randomly

Averaging 10% loss every hour
I am experiencing roughly 8-12%, so averaging around 10% loss every hour with moderate to slightly heavy use. Right now after 5 hours & 10 minutes i am at 50%. I have Facebook & an Exchange email synced and was on a phone call for over an hour, have been texting a bit and using email, the internet & Facebook. I have removed Sprint ID, which seems to run in the background along with Sprint radio, Nascar, Yahoo Stocks & News, so that may be helping a little. Overall I think that the battery performance has improved for me.

I was experiencing some pretty bad drain but after letting the kernel settle for a few days and disabling the location services, I can easily make it through the day

My batter time stinks!
I'm also getting 9% per hour battery drain. I have a Tasker profile running which turns off DATA when the screen is off. Most of the day, my phone has not been in use and I'm still getting battery drain. BetterBatteryStats shows that a process called "surfaceflinger" (Android System) has used the most followed by "googlequicksearchbox" followed by Gmail. Partial Wakelocks report says "signalCollector.Scanner has a count of 4844 and "LocationRecieverService" has a count of 3411 with "LocationReportingService" having a count of 5625. However, all of these combined only add up to 2% so I'm confused as to what is burning my battery.

Severe battery drain - Juice Defender problem?

My wife and I have this phone. A few weeks ago I installed Juice Defender (free) on mine and so far it's working remarkably well. Last night I installed it on my wife's phone and the battery level dropped precipitously. She wasn't using the phone much (if at all) and eventually plugged it in to charge it up. After fully charging, the phone wasn't used - overnight it just sat on the kitchen counter and the battery went from 100% to 17%. Never had this problem with my phone and can't figure out what the deal is. Does Juice Defender have a weird reaction under certain settings or installed apps that I don't know about?

I installed it one of the first days I got my LGOG, before it was rooted or unlocked and it killed my battery. I went through everything within the app and couldn't figure it out at all. Next step would be to contact the dev to see if he has any ideas.

Why not just use the builtin methods to save your battery?

I think I'm getting decent battery life with juice defender on

Man listen you do not need addon software to save your battery. It's useless! You do not need any software or app to save battery life! It's like me using pc with norton protection LOL. Turn your sync off.

I've been using jd since the day I got my phone... No battery drain problems. I have my settings on a semi frequent sync schedule (30mins) and can get about 1.5-2 days if I let the battery get close to 0. Check your settings... Both in jd and not.

I never partook in using these seemingly useless apps. From what I have seen over the years, these apps cannot really differentiate what processes need to run for system stability versus what is just eating up RAM and metaphorically killing the battery. I have never had success using battery saving or task managing apps, as they eventually always proved counterintuitive.
Want better battery life? Turn on Eco mode; lower your screen display; keep Wifi, NFC, and bluetooth off when not in use; and turn your vibration completely off.

JD does bring a few features you can't find in the native settings - I use it mostly to lower the screen brightness below the lowest built in setting for usage at night, as well as to quickly turn on data when I turn the screen on, and intelligently choose which type of data to connect to.
I think the main value is that I can get the best performance out of my phone (all cores, bluetooth constantly on so it connects instantly in the car, nfc on demand) when I am using it, and battery savings when I'm not. It's a very powerful tool, as long as you know how to configure it! It takes some tweaking but it's worth it.
That said, I'd contact the developers to see if you can send them some kind of log file to see what could be going on with the battery drain... They might be able to help, though JD seems to be out of active development.
