Hey everyone,
I'm not sure if I have an issue with a defective Captivate or if it running as intended. That's why I've come to you guys for some insight.
Here's my scenario:
A few days ago, I decided to leave my Captivate off of the charger overnight to see how much battery I would awaken with. It was just a little experiment I thought of to see how much the battery drains while not having anything intensive to do (such as power a screen). I fully charged the Captivate to 100% before setting it on my desk and going to bed. As normally, everything was turned off except wi-fi. When I awoken the next day (8 hours of sleeping), to my surprise, my battery was down to 27%. I was shocked that something could have drained almost 70% of my battery overnight. I downloaded an app called Spare Parts as a recommendation by some people and I seen "Running 100%" which means that the phone spent no time sleeping. When I look at any partial wakelocks, it showed "Android System" as a full bar. I assume that it could be a bad app that was keeping my phone from sleeping.
I restarted the phone, battery pulled, charged up and uninstalled some apps. Everything seemed back to normal as when I checked the the running %, it was proportionate to how often I was using the phone (not at 100%). I specifically checked if the phone was sleeping and it was through some monitoring. I would use the phone for 1 minute and then let it sleep for 2 minutes and you could see that the running % went down, as it is suppose to.
I kept monitoring the running % over the course of the day and it was fine. The less I used it, the lower the % would go; the more I used it, the higher. I also monitored what kind of apps I was firing up and I specifically made it an effort to not open any apps that were out of the ordinary. If I did, I checked to see if it kept my phone from sleeping and it did not (through my same usage tests as above). However, even after my close monitoring, sometime during that day, my phone would stop sleeping once again. I could tell because my running % never lowered, no matter how long I didn't use my phone. It would keep climbing which means it no longer slept. I made sure that I didn't do anything out of the ordinary too as I used the same apps as I did when the phone was sleeping fine. I checked "Android System" and it was getting larger. The battery was around 80%.
I charged up the phone again to max and made sure that nothing was preventing my phone from sleeping. Did the tests again and running % was proportionate again and I double and tripled checked to make sure the phone slept. I then left the phone not charging again to see what would happen as I would have no interactions with the phone to open any apps or change any settings. To my surprise, my battery was down to 60% (~ 6 hours of sleeping) when I awoke. I checked the running % immediately in the morning and it was at a very high percentage. "Android System", once again, dominated the partial wakelock portion.
So what's going on here? It doesn't actually seem like I'm doing anything on the user end to prevent the phone from sleeping. How come it decides to act up all of a sudden? If it was a bad app, how come it decides to prevent sleeping all of a sudden and not before? Even if it was a bad app, I didn't even launch anything while sleeping. Does the phone decide all of a sudden to stop sleeping?
The apps I use are:
Tasker
Y5 Battery Saver
Launcher Pro Plus
Twitter
SwiftKey
NHL Gamecenter
Handcent SMS
doubleTwist
Dropbox
Does anyone have the same problem?
Any help is appreciated.
Get rid of any task killers and battery savers they do more harm then good and most developers recommend not using them, they cause battery drain. The only battery app I use is Juicedefender because it keeps the phone from connecting constantly and keeps apps from running in the backround. I set it to connect every 15 min for 1 minute to sync, I turned off all notifications because they annoy me and I don't need to be notified everytime I get an e-mail or someone posts on Twitter or FB. My battery life has improved greatly once I dumped task killer. Also, I am running a Froyo mod and my battery is amazing now and my GPS works.
If you are in an area with a weak signal this will kill your battery because your phone is constantly searching for a signal and trying to connect. Also turn off wifi if you are not near wifi this will save battery.
Also try calibrating your battery and bump charge it. Here is a link for that. http://forum.xda-developers.com/showthread.php?t=765656
The battery will improve, mine got better after a few weeks of break in. I am at 60% been unplugged since 10 am and I made plenty of calls, checked e-mails, sent e-mails, checked XDA developement all day and I have plenty of juice.
Good infos. O agree with not using task killer

Hmm, thanks for the tips but there still seems to be something lingering around in my system that doesn't allow the phone to sleep. It seems to activate all of a sudden as well without user intervention.
I again left it overnight and it drained again when I woke up. I lose significant battery overnight when I sleep. I'm thinking about just restoring to factory settings. I've only had the phone for a week so I wouldn't lose that much data. I'll monitor it from the onset once I factory reset it and see if it's a hardware defect or something that was bad in my phone.
Do you have a live wallpaper installed? Also, do you have a bunch of Widgets on your homescreen? Are you constantly synching with e mail, FB, etc? No doubt something is running all night. It's not the phone, it's something you have installed. I set mine to sleep with Juice defender at night so nothing syncs. Check your wireless bill to see how much data is being sent while you sleep. Why not charge your phone while you sleep?

Nope, no live wallpapers and the only widgets I have on my home screen are the LauncherPro Plus widgets, Smooth Calendar and BattStatt. The only syncing I have going on is Google Calendar and Gmail but both of those shouldn't cause the phone to not sleep.
I was thinking of using Juice Defender but I would rather just get to the root of whatever app is preventing my phone from sleeping and kill it at the root instead of finding workarounds. For all I know, my phone may not be sleeping not just overnight, but with normal use as well and it would adversely affect battery life throughout daily use. I need the piece of mind that my phone is properly sleeping.
And I have no issues with charging while I sleep, but again, I need to find the root cause. If for whatever reason I'm can't access a charger overnight in the future (such as if I sleep over at my gf's house), I want to know that I won't wake up with a dead battery in the morning.
I really appreciate the help though.
As for what I decided to do next, I actually factory restored my phone yesterday morning and so far it is working well. I did not download any apps at all to make sure that this problem didn't persist with a stock phone. If it did, I would know that it's a phone defect and not something I did. Throughout the next week, I'll be installing different apps one by one to see any one of those apps will cause my phone to not sleep. This will allow me to isolate the app. It's long and tedious, but I would go through it for better battery life. So far, it's been working as I'm already through 10 hours on my phone with moderate use and it's only at 50%. Whatever was destroying my battery before absolutely had an effect on my daily battery life as I would struggle to even get 10 hours on my phone with moderate use.

I find your post very interesting. I have not yet used Juice defender, however, I am now more keen to battery drainage. I talked on the phone for about an hour the other day and my battery went from 100% to 40%. I find this unacceptable for a phone. Imagine taking conf. calls and conducting business in the field throughout the day. My battery would be dead in two hours without checking email
I hope you can reveal your findings to help us all.

Battery problem fixed using the simple technique similar to the one shared back in this thread.
I used to lose 10% per hour (or there abouts) and by 5 or 6pm needed to go on charger. At the very best with no use it dropped 3-5% in an hour.
Now its all changed...
After being off the charger for 35 min and taken 2 calls and sent a couple of txts she still read 100%.
At 5hrs 17min off the charger it is at 81% and there has been 6 calls in total and about 9 txts, plus a couple of appointments added.
Here is what they said to do and it worked...
1. Charge the phone for 8 hours, but make sure it is turned on while charging.
2. Unplug the phone, turn it off, plug it back in for 1 hour.
3. Unplug it, turn it back on for 2 minutes, then plug it back in for 1 hr.
Then unplug and enjoy the new battery life
Sounds too easy to work, but bugger me, it did!
27% is clearly abnormal.
Sometimes, I put the phone on it's charger after a pull day only using 27%.
I read somewhere on XDA that some early phones had defective screens that would only shut the backlight off and not turn off completely. Don't remember what came of that thread though.
I have a battery drain issue as well. My Captivate is 2 days old and been charging it every night. The first charge was done via the computer while transferring music over. After moderate usage (1 hour of music, browsing apps, learning how to use the phone, etc.), the battery died after 10 hours. GPS, and bluetooth was turned off. WiFi was used for maybe 20 minutes. When I got home, I charged it overnight for around 10 hours.
Today, the phone died on me after 9 hours. I rooted via z4root and applied RyanZa's latest OneClickLagFix, which both apps can be found on the market. Before that time, the battery said there was about 80% remaining. Fast forward to 6 hours later and the battery is gone. Again, moderate usage.
According to *#*#4636#*#*, my Screen On is at around 60%. A few other bars are pretty high as well, but I'm not sure how to do a screenshot on the Captivate right now. The only method I found requires using a PC. Plus, my battery is dead meaning I have to charge it overnight again.
I had an issue for the last couple of days, just figured it out earlier today. I had a corrupt thumbnail file on the external SD so my android.process.media (something like that) was constantly running.
I first realized something was wrong before I determined the battery life was bad when I noticed that my CPU was constantly at 11470-1200mhz or 975-1000 when I disabled the OC.
Unmounting the card would allow the CPU to drop to under 200 at idle so I knew it had something to do with the external SD. Turned out there was a bad file under a DCIM (camera folder), so after I deleted it, it became smooth as silk!
Of course it's still an i9000 rom so battery life is still questionable

Sorry for the hijack!
Here are yesterday's results:
Does these results look normal to you? I'm particularly concerned about the Social Hub and screen, and running. They're all higher than I expected. The brightness of the screen is set pretty low, maybe 2/10 of the brightness bar. As for Social Hub, well all I got is the Facebook widget, which is set to sync every 4 hours. Other kinds of syncing is off. GPS is off too. I don't have any battery saving type of apps yet, except for RyanZa's OCLF which includes the WiFi timeout.
I ended up charging the phone at 5% battery left. I had to sleep!
My battery charge fluctuates, sometimes it goes up from 5% to 35%, sometimes it seems depleted (2%) and if I check in 15 minutes it's 10% and so on.
I'm running CM 7.2 and previously Darky ROM 10.2. Since this started happening I've used a couple of the top-rated battery calibration tools, but to no avail.
Any ideas? Is it a hardware problem? Or a driver problem with the custom ROMs? Or something else?
Try the following If you haven't already.
Charge phone until it says it's full.
Discharge until it turns off. Try to turn it on to make sure it's absolutely flat.
Do this again.
Then charge it periodically so that you keep the percentage between the 20 and 90 approximately, and see if it improves.
Repeat first steps.
Wiping battery stats and similar "calibration" has no effect on neither the percentage shown or battery performance.

Thanks for the advice, I'll try it and see what happens. Any ideas to the cause of all this? Also, would buying a new battery help?
I don't really know the reason why this is happening, Li ion batteries can be somewhat of a black arts.
A new one should fix it anyway, and they're very cheap where I live at least

I passed through Same problem when i had updated my mobile to jelly bean for first time. But after 7-8 days fluctuates is decreased from +/-20% to +/- 2%. And fluctuates are gone after 20 days.
So dont worry, just wait for 20 days.
I have a Galaxy Nexus, not rooted, and it does this all day. 80%, 14%, 78%. All in a matter of minutes.
I'm discharging fully then doing a full charge to see if it changes anything.
My Sensation never did this and the apps I have are the same. In fact I've installed less on the Nexus...
same problem
i also have this same problem, check this thread...

Hi Guys,
How do I get rid of this calendar thingy eating my battery.
It's showed up after installing gregbradley's package.
I managed to stop Facebook and Google Services (they are still there but the no wakeup anymore... but still I'd like them to disappear not to loose functionalities) however Calendar this is very stubborn.
I wiped all remembered dates and nothing, I keep stopping it but it comes back.
Thank you for your help.
Regards,
Witek
Odp: [Q]Calendar eating battery
I see you use your phone not too often, 17h on battery and still 65% and the stat for the screen is only 5% so it means it was on for 51 minutes. Don't worry about the calendar, the amount of your processes that use the battery is so low that the stats show only the process that used the most battery. So it means that the calendar might have caused only 10 minutes of wakelock. So nothing to worry about.
Tapped from The Bond Phone!
It will only be an "issue" for a while until it has finished syncing.
Give it a day or two (Preferably) a week to settle down
For the last battery charge-discarge cycle Calendar stopped waking up at some 32 wakeups. Now after charging it's 39 wakeups already and increasing... I really want to get rid of it There is nothing to Sync on my callendar.
Do you suggest still to wait a couple of days more?
It's soon about to be the top drainer in my battery stats.
Hello!
I'm having some issues with my battery. Usually i get only about 3h30 of screen on. Normally, i charge my phone before go to sleep (so it doesn't stay all night charging), wake up with about 93%, and it goes all way down to 20% in +- 12-14hours (+9 hours of sleep).
I noticed that whatsapp is the most consuming app. Sometimes I look at the battery statistics and it's like 30% Whatsapp, 7% screen on, and other stuff less than 5%.
Someone have had this problem? It's really annoying, I see people getting 30~40 hours, 6 hours of screen, and i can't get even close to that.
Cheers
try uninstalling the app and test it again. i ended up draining my battery to 10%.. turned the phone completely off and charged it to 100%. now my battery lasts quite a while, 2-3 hours with just 2-3%. light usage of course.

You and me both, pal. I tried everything to make my battery last 6 SOT and nothing. I think it's whatsapp and play services, but i can't get rid of them.

I do have a problem with Play Service but it's gone for like 2 weeks ago after I played with some Google Apps. What I do is Disable Google Search, cut off Google Now, change Sync option in Google Setting. It just disappeared. I think you should go to Google Setting and try to turn off anything you don't need.

I'll give it a shot. Thanks for the advice. I was using CM12.1 with Play service "Keep awake" and "Wake up" disabled in Privacy, but for some reason the battery lasted less in this setting than in almost out-of-the-box stock ROM.

Also you should consider that WhatsApp is now showing itself on the battery graph, and for me is also one of the top consumers always. Before Lollipop, WhatsApp wasn't showing itself on the battery graph.
I have been able to get around 40hrs with 6hr SOT, and still WhatsApp is the top battery drainer.
I think you shouldn't be worried about WhatsApp, but you should look to other apps or settings that could be draining your battery.

I have not rooted my phone, running 5.1.1.
My phone is draining like 10-15% per hour with very minimal screen on time or idle. more than that when I'm using my phone. Last time I checked, using Gsam, I was 4 hours off charger, an hour 30 of screen on time (most all of that was twitter and and using groupme) and i was at 34% battery. according to Gsam: screen used 29%, wifi used 30%, and app usage was at 33%. of all my apps, android system and kernel were the only ones above like 5%, so no rogue app according to gsam. That whole 4 hours I have been at my house with a stable wifi and cell signal.
I will get a screen shot if needed. But how can I figure out what is causing the huge wifi drain? "turning off wifi" is not a valid fix either. wifi should not use more battery than the screen and basically the same as all my apps.
Any ideas would be greatly appreciated.
Thanks in advance

Mine is acting pretty similarly. Usually I cannot break 2 hours of SOT in around 6 hours of being off a charger - pretty bad. I hear the Facebook app causes quite a bit of drain, so I'll first be getting rid of that to see what happens. If that doesn't work, I'll probably go the route of a factory reset. Maybe these might work for you too?
I'd also check and see what your location settings might be. High accuracy seems to be a killer. Same goes for HD voice or whatever it is for calls, which can be turned off in the settings.
Good luck!
I have hd voice disabled, i just disabled facebook (since its factory installed and they wont let you uninstall it, i hate that). i also turned off google fit, i'll see if that helps.
did anything help?
