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)?

I'm not a power user.. but I'm getting ~2 days use simply by using Timeriffic with a schedule such as
11pm - turn on Airplane mode (ie. shut off all radios).. I'm in bed and dont want to hear from you
6am - remove Airplane mode
7am - enable Bluetooth while I drive to work
8am - disable Bluetooth, set ringer to vibrate
5pm - turn ringer back on, enable Bluetooth for drive home
6pm - turn Bluetooth off
rinse, wash, repeat (the 7am,8am,5pm events are only on weekdays).
There are multiple apps which support this kind of thing.

I've gone through this with every Android phone I've owned. Juice defender etc just isn't for me. In my opinion it just takes away one of the main features of having an Android phone in the first place.
With a few battery cycles, the battery life will improve. Once we have custom roms it will be even better.

One thing that many people forget about is how often email syncs, how often you have your weather syncing, and any other apps that sync.

Menu / settings / about phone / tell HTC / remove V on both settings and i dropped down to 38ma with wifi on in standby.
5 minutes later i got 6ma.
If this is what was taking all power from the phone i will have a super phone with the best battery

Remove V on both options? huh? I see: Report Errors to HTC checked and two dropdowns.

See if just don't get you people. If your just using your phone for bluetooth vibrate rinse not repeat etc? Wtf why do you have a Sensation 4G? It's a powerhouse phone so if your attempting to get 48 hours of battery life(which basically means your phones screen is never on) Why waste 250 on a phone. Get a dumbphone with bluetooth and your battery can last you a week. Now if your a regular person with a smart phone you simply accept that your battery life will be shot your trade battery life for perfornance. If your emails aren't syncing, facebook, twitter, weather, google music, etc. Then a smart phone is pointless. I use my phone white a bit and i've been getting about 9 hours usage with my phone which is greatttt I play angry birds every thing syncs facebook twitter gmail aim Battleheart etc you name it and I get over 9 hours on a single charge that is great.

If you are not killing your battery in four hours or less, you are not using your phone. Lol, in my opinion.

People get Obsessed with battery usage.
What is the point of having this or any superphone if your gonna cut it's balls off from day one.
If you condition the battery properly from day one, you can use it heavily and still get easily a full day....and that's more than anyone should ever ask for from a device this powerful AND beautiful

Sorry maybe you missed the point of the thread..........
There's no such thing as a regular user as you state, everyone does things differently. The point of this thread is to contribute methods that extend maxing out our perfomance, game playing, and all productivity on our devices. If you have nothing to add besides rants and flames, I suggest you just hush, watch and learn.
Right now we can't access/disable some programs that really drain juice. So every little bit helps til we get root.

yea its reading the information from the device wrong. email the developer, email address is in his program on the android market

I dont know why I bother having a smartphone, it spends so much time in the charger, I might as well call it landline

First thing, I stopped using all battery and current monitoring apps when I realized they were a part of the problem and not part of a solution. They are simply drawing power and keeping the phone awake and are not really accurate anyways. Only actual usage time matters. Can you use it throughout the whole day with "normal" (for you!) usage patterns?
If you have something draining your battery over time, it is likely to be an app keeping the phone awake so it doesn't go into deep sleep mode.
Connect the USB cable to the phone and PC and run this command:
Code:
adb shell dumpsys alarm > AlarmDump.txt
Then have a look at the file, towards the bottom you get Stats. In here is the breakdown of what's causing the device to wake up. (h/t catnap)
The screen may be the single biggest drawer of power, so I usually suggest disabling auto-brightness and setting the brightness to a level you can work with, for me around 25% works. I also edit my build.prop and change the supplicant timer from 120 to 900 to prevent WiFi from pinging my remembered networks as often, turn off open network notification, and run the mobile network on 3G instead of 4G since it uses less power.
Some other things to do include turning off pocket mode under the sounds settings (turns off proximity detector) and disable vibrate feedback.

I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Also, Turn off GPS and Wifi when you're not using them.

Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.

Thanks for all the advice this has really helped my battery

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.

I found that juice defender helped my battery and i just use the free version it's a great app

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.

Syncwifi application is awesome for extending sync settings to gain more battery
Sent from my SAMSUNG-SGH-I997 using XDA Premium App

Using titanium backup I froze drm content 2.2.1 and this significantly increased my battery life.
Sent from my Infuse. It is what it isn't.

JuiceDefender!!
I agree JuiceDefender works!! I had to charge in the middle of the day. Now with moderate use it will last all day Im on stock Rom.

I easily get 2 days out of my Infuse, no idea how some of you are managing to only get 8 hours. After rooting my phone and freezing the bloat i easily get twice the battery life of my prior iPhone 3GS.

Battery drain

Hi,
I have a HTC Sensation, not rooted. I use an 1900mah battery based on xda and other forum experiences, and it is better than the original but I still have problems. I use battery mix app for monitoring the battery use and usually it says CSPEOPLESYNCSERVICE is using the battery, always at least for 45%! If I unplug the device from the charger at around 8 o'clock, at the afternoon at 4-5,it's around 45-50%. The usage is basically 30 min music, 10-15min gaming, 20min browsing and approximately 20 min of voice calls and a few messages on whatsapp. I have unticked the sync for all the contacs( fb, skype, whatsapp, gmail etc) but when I check the battery usage in battery usage it still shows CSPEOPLESYNCSERVICE is using my battery mostly. If I check basic android battery usage it just shows mostly the display uses it. I have searched a lot about this problem but nothing found. I don't use anything special, I don't use appkiller, antivirus or any app that could run in the background. In my opinion it's not normal, thsi way my 1900mah battery with normal usage ( during the day I work, and not really using my phone like gaming or etc) lasts for 12-14 hours.
Thanks

Your battery life will improve if you set your network mode to "CDMA Only" rather than "GSM/CDMA Auto", because it forces your phone to stick to one network instead of searching for others.
Your battery life will also improve if you use a low-med static brightness setting rather than auto-brightness, since your phone will not be using its sensor to detect the background lighting.
It will improve further if you use an app that controls your network usage such as Green Power Premium which controls when your network should be on and off. Also it has a great feature that makes your phone to sync when network is on, rather than most battery apps that just turn on network pointlessly waiting for phone to sync itself.
Hope this helps =)

[Q] Battery life not as it should be?

Hi
First of all I'm back on Android and back on the forum after four years of iOS, really enjoying Android and the forum again!
I just got my Z3 for about 2 weeks now and I'm not getting the 2days out of my single charge, when I take the charger out at about 7 in the morning, I'm left with about 30-40% at 11 a'clock at night. I'm just wonderring if these 2 days should be able to reach with heavy whatsapp usage (groups, really almost receiving a couple of messages a minute ) and moderate Facebook, Snapchat, browsing, and maybe some app downloads? Are there some settings you guys recommend to increase battery life? (already using stamina, doesn't really make a big difference).
Thanks in advance!

You can follow the battery life thread.
I have autosync, location and WiFi calling enabled and I still get 6-9 hours of screen time out of a 24 hr period with heavy usage with or without WiFi calling. At first I got no more than 5-6 Hrs screen time but as I used it and it settled/calibrated it got better.
Whats your signal strength like? It can have a big impact.
As for battery saving tips:
Try turning off or reducing the nunber of apps syncing. Facebook can also be a killer at times, I disabled, I barely use it and when I do need to I just use the mobile site.
Also turn off background WiFi scanning and set the following option -> WiFi off when screen off or on w/screen off only when connected to power.
Lastly try calibrating the battery as even Apple as you probably know reccomends for their devices:
1. Full drain
2. Full uninteruppted charge
3. Discharge with regular use to 0-1%
4. Full charge and use normally
As for stamina its not done anything for me either so I disabled it. More like placebo effect lol, I think they will fix it.

Thank you for quick response!
I've searched for a battery life thread but I couldn't find one, where can I find it?
My signal strength most of the time has all the bars, except at my house I have only one or two bars in various rooms, I didn't know about its big impact so this might indeed be a reason for my battery drain. Turned off almost all the syncing for my apps, and did the WiFi settings you mentioned, if the setting 'WiFi off when screen off" is enabled should my WiFi be of when I light up the screen without unlocking my phone or just really when the screen is off? Thanks for the tips, I hope I can get more hours out of it now!

At some time I had a short battery too and after those same steps I have 3 days battery without any problem:
