7 hrs of Standby = 33% of Battery?!?!

Okay so I noticed my Captivate seems to lose a lot of battery while in standby. To test this, I left it unplugged when I went to bed last night. I checked the battery level right when I went to sleep and then again when I woke up...
My battery drained from 64% to 31% in about 7 hours!!!
I know other threads discuss bad battery life. A bright screen and a 1GHZ processor can cause this so I can understand why the phone won't allow me to browse the web for 10 hours straight. But is everyone else getting an almost 5%/hour drain in battery while in standby?
Here is a little info about my setup:
-I took off an animated background and put one that is relatively dark (Screen is off during standby so I would think this doesn't matter)
-I have WiFi and Bluetooth enabled.
-I use both wireless networks and GPS for location.
-I have 1 Gmail account setup to check every hour.
-I have the Daily Briefing set up to check every 3 hours.
-I have the Slickdeals widget set to check every 2 hours.
-I have the Latitude widget running (you can't set how often it refreshes).
-I have the ESPN ScoreCenter widget running.
That's about all I did that I can think of that can possibly affect battery. I know I would get better battery with less background widgets, but all of this is in line with the amount of background services I had running on my last phone (Tilt 2) and that thing would last for several days with light use.
So, what I'm trying to find out is whether or not this is normal behavior that everyone is seeing or perhaps if one of the background widgets I'm using is known for draining a crazy amount of battery. Maybe I need to hard reset the phone? Thanks in advance for any ideas on how to lock this down.

In poor reception I could see that. But I'm good area that's too much. Like 2% every hour is good... 5 is too much....

Thanks for your reply. I had 3 bars of service where I was last night. Also, this isn't the first time I've noticed about 5%/hour for standby, just one example...
So it sounds like I'm getting worse drain than normal? Now, how to fix it?

Well...with all the email checks and having various Widgets check for updates..it will definitely drain the battery. I have been able to easily get twelve+ hours on standby without GPS on and turning off wifi when not at home or in a place with wifi.
Definitely can't go days without charging like I could with previous phones like my blackjack II buy I can get 12-16 hours with light to moderate use and 10-12 with somewhat moderate use of Facebook, wifi, various other apps.
EDIT: the Bluetooth as well will drain the battery.

I have very similar battery usage to use. About 5% an hour not doing anything. I am always around a wifi and leave it turned on. I have nearly an out of the box setup. Between the poor battery life and crappy GPS, I may very well be taking this thing back.

Under Settings > Wireless and Network > Wi-Fi settings > Bring up the Advanced menu and set the Wi-Fi sleep policy to "Never".
This has helped my battery life immensely, since I am around Wi-Fi most of the time. This way all your data happens over Wi-Fi instead of 3G when the screen sleeps. I disable Wi-Fi when I'm not around any APs I normally connect to.
Pulled phone off the charger at 6:00AM yesterday morning. Streamed an hour and half to 2+ hours worth of Pandora over wi-fi getting ready for work and then some in the car. Did some web surfing during the day, various other things. (No phone calls really, except a brief wrong number). 4 e-mail accounts checking every 30 minutes (one an Exchange server). Also have Touchdown running push e-mail for another Exchange mailbox along with the Touchdown widget. Played around with some GPS apps (new google maps, Places, etc for a few minutes). Battery was down to about 16% by about midnight last night.

My phone charged fully overnight (with power off). Was turned on at 7AM, it is now 11am, and am at 90%.
I do not use GPS, have nothing running, no emails or social networking status updates.. The phone is on standby on my desk. I only do a few text messages and 5 minutes of voice calls / day.
So this means I get 40hrs of standby time? That is a little ridiculous.
I chatted with AT&T tech support and they said that the AT&T stores don't have battery replacements yet, but I could get a full phone replacement since I am within the 30 days still.
But from what I am hearing, it seems most people are having the same issue if not worse, correct?
I really don't want to set everything back up AGAIN. I am coming from using a Samsung Eternity - understand it isn't a true "smartphone" - but I use it the same, and would easily go 3-4 days without needing a charge.

with GPS off, wifi off, BT off, no data sync or background data turned on, i charge it fully at night -
last 3 nights in a row, at midnight it was showing 100% and at 7:30AM it would show 97-98% remaining, and that was using the alarm, set to loud and probably ran 2 minutes before i'd hit the off button

From 7:30am-11am, I have used 4% of my battery. I have these things going on:
-Exchange sync (real time)
-Facebook sync (once every hour)
-wireless off, bluetooth off, GPS not being utilized
-Weather.com and a Google search widget
The battery use shows this:
-Cell standby: 48%
-Phone idle: 36%
-Display: 8%
-Android System: 3%
-Email: 3%
-Android OS: 2%
I've barely used my phone this morning, so I'd think 4% of use in 3.5 hours is quite acceptable. It sounds like you need to make some modifications to improve your performance.

firehazard - what modifications have you done? I have wifi/bt off, background data off, no email syncing - display brightness all the way down..

To anyone who is having very poor battery life, I suggest a factory data reset when you exhaust other options. My phone wasn't lasting me more than about 8 hours on a full charge, with light to moderate usage. After a factory reset, I just ran nearly 24 hours with similar usage.
I can't tell you what changed or what got removed, maybe it was an app that was running and draining the battery that I didn't see, but battery life is MUCH better now. Hell, everything is running much better, even the GPS.
I went from wanting to throw this phone at a wall and return it for my iPhone 4 again, to loving it in less than 24 hours.

I'm referring to him running wifi and bluetooth when he's not even using his phone. Stuff like that.

Just for recording keeping, when a phone company says their phone can last XXXHours in Standby this means, that all wireless transmitters are off. this means (for the most part) airplane mode, with bluetooth, and wifi OFF.
these continuous wireless transmitters are why you didnt get the 200Hours or what ever it is in standby mode.

I recently took my phone back to BestBuy for a replacement since my battery was trying to kill itself overnight as well. I did the full charge when I first got it and purposely ran the battery down to quickly get it to turn itself off at 0%. Did a full recharge and repeated this process about 3 times and last night my battery only went down 3% over 6 hours. Compared to the 30-40% that was draining before, I'd say the full discharge/full recharge works that people have been talking about in the battery threads works. Thanks, everyone! I use Y5 to have it automatically connect to my WiFi at home when it's in range. Not much more than the usual was left to sync (although JuiceDefender may be working to turn stuff off when my screen is off) such as Gmail, Beautiful widgets, facebook, and one rss feed.
Either that or I had a crappy battery before

Seems like some folks are having the same problem as me, while others are having much better results. Firehazard's situation and drain while not in use is pretty much in line with my expectations of the phone. With my old Tilt 2, I left WiFi and Bluetooth on all the time and still got great standby time out of the phone. When those connections weren't in use, they weren't really draining my battery in any way. I'm going to try to disable them though and see if that helps. I'll also try to monitor the battery usage screen and see how much power is going to wifi and bluetooth when I have them on.

I've been suspicious of my battery as well, tracking it casually today.
Took it off the charger approx 8:30am, immediately went to 99%.
Watching it over the last hour it appears to be losing 1% / 10 minutes.

Just using it for the past 5 minutes to write up everything running has dropped the battery almost 3%. Albeit I have terrible cell coverage where I am. It does seem that the cell and wifi receivers are a bit weak, or the meters are biased conservatively.
*edit* I want to be clear that I love this phone, I just want to try and find out what and if certain services/applications drain the battery and if not then if I have a bad battery.

Okay, so I turned OFF bluetooth and WiFi and checked the battery before bed and right when I woke up. This time, I lost 24% over 8 hours. Certainly a big improvement over 33% in 7 hours, but also no where near where my old Tilt 2 was. I would lose 2-3% overnight at the most with that phone. I checked the battery meter and the majority of the battery went to Cell Standby and Phone Idle. Those don't seem like things that can be avoided through tweaking. I was in an area with 3 bars of service (same as night before), so I don't think that was an issue.
I'm debating whether or not I should try a factory data reset. Some folks reported good results with that. I really don't feel like reconfiguring my whole device if there isn't a good chance for improvement. Maybe the GPS fix that's coming will help battery life?

Have you tried reconditioning the battery? That would be the charging/discharching cycles mentioned throughout the forum?
I have done it and my phone has been on standby for more than 24 hours and I am still at 50% battery. It's just had very light usage. Wifi on for about an hour, snapping a few pics, deleting some others. A bit of calc usage. When I first got it, my battery was dismal.
Mine hasn't been modded one bit yet, just installed some apps from the market and a weather widget.

Yes, tried that. It actually helped a little but I'm still getting poor results compared to some.
I have another theory/question. I use gmail as my only email account on my phone. Its set up through the system and it syncs to the gmail application on the phone. I also have it set up in the Samsung default email client (which I prefer). Am I wasting battery because the two apps are checking mail independently? Does the gmail account sync while the Samsung one checks at intervals (I have mine set to 1 hr)?

probably.
follow battery optimization guide in pimp my captivate.pdf thread. I get 1-2% battery consumption per hour with moderate to light usage.
heavy usage drops my battery about 4-5% per hour. By heavy usage I mean playing 3D games for hours str8

Android System keeping phone awake?

Android System
Settings Storage
CyanogenMod settings
VPN Services
Settings

How do I get rid of this wake time? I have a CPU foreground of 57s but Keep awake of 1h 0m 7s. My dialer is was also awake for 45 minutes as others have reported.
Someone help!

What is your display on time?o usually the android system counts as awake when screen is on.

Pretty sure that is not accurate. Screen wasn't on for an hour anyway.

Does your phone stand-by on WiFi and WiFi sleep policy = NEVER?
Because I got same issue with Dialer is awake:
http://forum.xda-developers.com/showpost.php?p=11015261&postcount=12
Last night it was awake for more than 3 hours!
And I did not use my phone for calling, only sending couple of SMS.

[Q] Nexus S stock 2.3.4 and how to check keep-awake culprits

Hey guys,
N00b here.
I've read the n00b guide and also searched around in the forum. I did find a thread similar to mine however I couldn't really get any useful info out of it and maybe since then new tools are available to help me track my problem, so I post my question.
So... on to it...
My Nexus S is suddenly having high keep-awake times. About phone tells me a battery usage of 32% android system, followed by 21% Display. Android system has a keep awake time of 3h 51m and a CPU total of 7m 52s. All this over the course of 19 hours. I don't have a screenshot with me but it's clear that the phone is awake a lot when the screen is off.
Automatic updates are off.
Some days ago everything was fine. My google acount is only synching contacts and calendar and even that is turned off when I'm not at home. Even so, I saw a high usage of the keep-awake bar even when the screen was off.
I've installed some weather widgets and battery info widgets and the update cycles of weather applications are around 45 mins so I wouldn't see a reason for such a high period of keep-awake cycles.
Anyway, each phone is a phone, is there an application that can tell you what is keeping the phone awake ? I have installed Watchdog lite but it doesn't show anything abnormal. I've installed Spare Parts Plus but it can't show me the battery usage history because apparently stock 2.3.4 Gingerbread doesn't support it.
So now I'm stick with trying to disabled notifications on one app, remove its widget and see if it helps. If it doesn't.. go to the next. This is quite tedious work really.
Still the battery life is ok I guess... 50% after 19 hours however I haven't played around with it much but I would be happier to have a low keep-awake cycle for the Android System like I had some days ago.. makes me feel like everything is fine
Thanks for any hints guys!

Having the same issue as well.. I have my widgets and such to only check every 4-6 hours, but the awake time in the battery stats is nearly on all the time.
Keep awake time is 4 hours and 22 min, out of 12 hours of battery. I'm left with 42 % battery with only 1 hr 15 min on screen time (texts and such, no games).

Hmmm a memory drain of 60% in 1 hour is quite a bit heavy. I would suggest you to download Watchdog lite from the app store and use it's real time CPU analyzer to try and see what's consuming the most.
Once I had weatherbug going rogue. But then it showed up in the battery usage list with a high CPU usage and clicking on the item I could see a high awake time so I uninstalled it.
At the moment I've removed some of my widgets and so far it seems to be OK. However tonight I had some weird awake times again. I uninstalled Battery Info widget from the phone and I'll see if it all goes well tonight. Then I'll start to activate the other widgets I had deactivated before to see what happens.
Also I downloaded aCatLog from the app store. Pretty interesting tool... you can see what's going on in the logs. I see a few Java exceptions every now and then.. never a good sign as they might not be handled properly by the application code that threw them. I see evernote synch problems, a data traffic counter throwing exceptions and K-9 to have problems with idle connection reset by peer. And I often see the garbage collector working. But I assume all this is normal. Switching to the event log it's too much information to absorve. Nevertheless I haven't seen in any of those logs an explicit request or grant of a system wake lock.

Do I need to download Terminal Emulator from the market to do this ? Or do I need to download the Android SDK and connect to the device via USB ? I need to check out to do this, never done it before and this is my first android phone.. only a week old

Again this morning my awake time was on for quite a bit (I guess 1 hour). I got an extract of the main log...
Some things are curious, the following occurs more or less each half hour. I am signed out of gtalk why was the service trying to keep alive ?
06-08 06:10:03.656 W/GTalkService( 189): [GTalkConnection.18] doConnect: caught XMPPError connecting to mtalk.google.com:5228.: (502)

Evernote seems to have some issues as well sometimes

And that's all I could see. Everything else seems to be garbage collection WiFi activities and what not..

It seems that I've narrowed down Go Weather as what's making my Android System stay awake. I couldn't see anything really useful on logcat about this but empiric observations seem to confirm it.
If I remove the Go Weather widget and turn off it's background updates (hourly), then restart the phone... I see the Android System incrementing some 3-4 mins keep awake time per hour. If I set the widget again and turn on Go Weather's background updates, after an hour the Android System keep awake time goes up like 15-20 mins or so. If at this point I remove the Go Weather widget and turn off it's background updates, the Android System keep awake will still go up at the same rate as if the Widget was there. If I restart the phone without the widget, then the Android System keep awake seems to increase back to regular 3-4 mins per hour.
The funny thing is that according to Permission Dog, Go Weather doesn't even use the WAKE permission so I would rule it out as what was keeping Android System awake.

Android System was driving me crazy too. I figured out that when my WiFi was enabled, it would continually keep the phone awake when the screen was off. So I just toggle the wifi off when I'm not using it, and android system behaves now.
I'm curious as to what changed though, because when I was using stock 2.3.4 and CM7.0.3 I would leave wifi on all day, and android system didn't cause any battery issues.

[Q] phone is always awake

nothing out of the ordinary running in watchdog or running services.. when i go to bed at night with full battery i wake up and its around 50% with NO USE.... i look at battery history and it says the phone has been awake 100% of the time,,, back ground data is off, auto sync off, already deleted facebook and twitter and picasa, location and gps off, cant understand why phone is awake 100% of the time, how do i find out what is causing this? its really annoying ... and yes iv searched

Two things. One have your tried wipeing I know it sucks but that might be your only solution. Two when I read the title of the article all I could think of is Samuel Jackson reads 'Go the **** to Sleep'
Sent from my HTC Sensation 4G using Tapatalk

lol ...ya i wiped and formatted system, cache, dalvik before i installed melvin's rooted stock 2.3.4...its weird because if i restart the phone it shows that it is sleeping now intermittently but i did the same thing yesterday and all of a sudden it started having 100% awake time again...

Install BetterBatteryStats (https://market.android.com/details?id=com.asksven.betterbatterystats). Created by a fellow XDA-member. It shows which app keeps your phone awake.

thank you for pointing me to this app, its great... it says that about 90% of the awake time is CSPUSH (com.htc.cs.HTC Sense), but the count is 25...so how do i interpret this since its not an app i can uninstall? it also tells me that alarm manager's count is 2044 but only .1% of wake time, why is that count so high but so low on the % awake time?

ok so iv got cspush 8 hrs count :25 90%, activity manager 2m count:548 .4%, alarm manager 33s count: 2099 .1%, checkin service 30 s count :419 .1%, RILJ (dialer) 27s count:766 .1%, sleep_broadcast 18s count: 761 .1%, *vibrator* (android system) 11s count:1130 0%, SCREEN_FROZEN 8s count: 771 0%, activity manager-sleep 1s count:2156 0%... these are the ones that seem to have the highest numbers for percent or count in BetterBatteryStats, can someone help me determine whats causing the solid line for awake on my battery stats while im sleeping please?

Have you connected your phone to htcsense.com and/or HTC Watch? Try to remove that or those account(s). Both services are known to drain battery.

battery drain

Hi.. i lost 20% over 5,5 hours in standby mode.. is that normal or something sneaky going on?

Do you have any apps syncing all the time? Some news apps sync every 15 minutes or so.

That seems like a high rate to me. Have you messed with any of the power options on it (made it not go into standby, etc...?)
I barely got that much drain watching a 3 hour movie.

I'd also check email syncing - if you a bunch of accounts that sync very often, it can affect the battery as well.

Also make sure your Bluetooth is turned off.

It happens to me sometimes and it seems like a reboot fixes it.

A reboot does sometimes work. Otherwise also make sure you close out office programs. I've noticed that sometimes runs down battery a little, though not that much. Are you hooked into WiFi, and is the connection where you are reliable?

i uninstalled few apps and rebooted and its okay now.. maybe it was because of Appygeek app.. try it out

Turn off all live tiles (maybe except mail, messaging and people which are useful) and don't allow any lock screen apps to run in the background which you can change via pc settings. This should significantly improve battery life.
