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
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:

The battery thread is in "General" its called "Battery Life is Insane".
Soo! again with another battery post..
Okay i followed some rules someone helped me with the other day in regards to resetting the whole phone and updating it, which i did and the battery was fixed! now untill about 2pm to day my phone was lasting all day i mean since 8am it went from 100% to around 70% and said i had like atleast 1 day with stamina mode on..
Now its at 65% its telling me i have 4 hours remaining without stamina mode and now 11 hours with stamina mode..
Can someone explain why to me? i mean i don't think i have loads of things on that are heavy on battery life.
have you looked at the battery stats to see whats eating the battery?

Mainly the screen, i noticed tho soon as i had to use my phone to be a satnav on google maps it enabled high active location settings, but after i finished i turn the location settings back to battery saver mode so i cant see why it hasn't changed the battery daily span, i mean the screen is the biggest consumer at 29% then snapchat at 15% then some more social media but there below 14%
gps and using it as a sat nav will use the battery quite a bit as the screen is always on, try turning the brightness down
I just, cleared the date and cache on my stamina mode and reset the phone and it seems to have fixed it, i will apparently get 4 days and 11 hours out of my stamina mode now on 96% battery. i have adaptive brightness on tho btw, so i'll just turn it off and lower my screen too

There is a bug in the Stamina Mode statistics. They will only work for the first day and then start showing the wrong time remaining, but don't worry about it. Although the time remaining is wrong, Stamina mode should still be working. You can test this by allowing the phone to sleep for 30min when connected to wifi and then wake the phone to see if wifi is still enabled. If the wifi icon is not showing, but then pops up shortly after waking the phone, then Stamina Mode is working.
Let's investigate the hourly battery drain!
To start it, mine after 5 days of usage is close to 3% per hour.
Your results will be varied. You really need a lot of information to compare usage and battery drain.
1. LTE vs no LTE
2. If LTE what is your signal strength (can be negligible or a huge battery drainer)
2. BT state
3. Wifi State
4. Location Setting On/Off
5. AOD state (the number 1 battery drainer)
6. Tilt to wake state
7. Amount of notifications/calls/text
8. Screen Brightness
This is a tough are to analyze unless you have everyone state what their setup is like. You will have people that use minimum settings and report 4 days. The people that use all features and get 1 day will wonder why they are not getting 4 days use. Until you compare similar setups and usage don't get overly concerned with what others are getting.
My setup:
1. Version LTE (T-Mobile)
2. Mobile Network set to Auto (I am in a strong coverage area) ( I leave my phone on my desk and go into stand alone mode several times a day)
3. Call Forwarding On
4. AOD On
5. Tilt to wake Off
6. Location On
7. Wifi Off
8. emails~25, text~15, calls answered on watch~2 (1 minute calls)
With those setting I get 3 - 3.5% battery drain per hour. Full day use 7am - 11pm I put it on the charger with about 50% battery remaining.
Frontier BT version
Aod off
Brightness 2
Dark watchface
Wifi off
Location on
BT always on
~50 messages/d
~10 phone calls/d
1 hour/d playing with new apps and stuff
1 hour/d running or exercising
GS3 Classic BT
1. no LTE
2. N/A
2. BT connected
3. Wifi when BT disconnects (never)
4. Location Setting Off
5. AOD on
6. Tilt to wake state enabled
7. Amount of notifications/calls/text - 30 notifications/hour
8. Screen Brightness - level 3
Close to about 4%/hour with the AOD. I wish we had a way to disable seconds display in AOD because that would probably save some power.
Really kinda roughly the same energy drain of my Moto 360, Huawei watch, and Gear S2. I expected better. Still a sweet watch tho.
1. T-Mobile LTE
2. If LTE is on I use about 10% battery/hr because of crap signal
2. BT auto (primary method of connection)
3. Wifi auto
4. Location On
5. AOD off
6. Tilt to wake on
7. Notifications from phone only if not using the phone
8. Screen Brightness at 8
With that I get about 3 to 4 days of battery life on average (excluding using any LTE).
With LTE enabled I would expect a lot less, where I intended it to be on, at my place of work, it's constantly searching for a signal or has a horrible connection possibly helping to drain the battery. Not sure how it would perform where I have a good signal strength though.
**Edit**
Also, now that I don't use LTE while at work, I use airplane mode and I lose about 1% max every 3 hours.
I get around 3.5 - 4% per hour. But I have EVERYTHING maxed.
non LTE version
max brightness
max volume
AOD
vibration
location on
gps
wifi auto
bluetooth connection to phone
All s health tracking (steps, HR etc)
weather sync every hour
all notifications (email, SMS, Whatsapp, Google, Facebook, Instagram etc)
tilt to wake on
Another observation, at night, lying on the table, it consumed 5% in 11 hours giving 0.45% drain.
My first week with the S3. Came of charge at 7am on Monday and lasted until Saturday 7am. This represent a drain of less than 1% per hour.
AOD and tilt wake-up off
Brightness at 7 with dark watch face
Bluetooth on for notifications and weather
Wi-Fi off
Tracking sleep at night
Not tracking anything else
Location off
Amazing watch. I love the size. I miss the s2 classic impeccable build quality but battery and GPS tracking are too good to skip.
My main issue with the s2 battery was the drain when listening to mp3 on Bluetooth headset. The s3 still drains quickly but not as fast.
From 100% to 84% - 24h so, less than 1%
Non-LTE
AOD off
tilt wake-up on
Brightness at 6 with relatively dark watch face (Alpha Dark)
Bluetooth on for notifications and weather
Wi-Fi off (on if BR disconnect)
Tracking sleep at night
S-health - tracking steps, floors, etc
HR on
Location off
S-Voice off

It consumes about 1% / hour whilst I'm wearing it during sleep, so about double that.
I have to say this watch is totally not consistent with a lot of things. I can live with it for now but for example I walked about 20 floors today (12x3 meter + 5 or 6 times 4 meter at work plus just now 2x4 meter at home) and the stuoid watch counts 3 floors. What a mess. It also keeps insisting I live eiher 18 meters below sealevel or 20 above and hilariously I did a run yesterday showing an elevation of -112 meters.
Just got my S3, so I'm not goin to chime in yet. The first week or two will be brutal for the battery because I'll be in "ooooh new toy" mode. Once my usage settles down to casual, I'll have a good idea of battery life.
As the title says... is there something wrong with my battery? I got abysmal SOT of 4hr35min on mobile/cellular data only (No WiFi). Bluetooth OFF, location OFF, dark mode OFF, brigtness 40% or less, Samsung Cloud, Google Photos & Google One back up & sync - all OFF,. Bixby home, bixby wake up, literally everything bixby related OFF. Wake to lift OFF, smart stay OFF. Optimized battery settings, exceptions to optimize made on gmail, whatsapp, instagram. Everything else on optimization. AoD - always on, dynamic background on home screen - yes.
Also worth noting - after fully charging the phone, I went from 100% to 98% in like 3 minutes. I also went from 5% to 0% in a couple of minutes.
Is there something wrong with my battery? Surely 4 hrs 35min shouldn't be a norm, not even on cellular data only.
Signal Strength plays a huge rule in battery consumption, ever thought about that??
How many dBm's you get?

It was in between -87dBm to -104 dBm. Screenshot provided. I honestly doubt its a signal, but cellular data really doesnt give me more than 5hrs SOT which is really bad....
First of all, I did a factory reset. Then, I did 100% do 0% and then charged the phone while OFF to 100% again and other time I did 100% to 0% and charged it while turning it on after couple %.
I also disabled EVERYTHING Bixby related AND I disabled Facebook running in the background.
The result are in, aaaaaaand.....
MASSIVE IMPROVEMENT!
I am now getting at least 7hrs 30mins with 70%/30% wifi/mobile data usage.
On WiFi Only, I can now get EASILY 9 hours SoT
See screenshots - #1 & #2 showing 7hrs 30mins wifi/mobile data. Screenshot #3 WiFi only, 8hrs 22mins WITH 22% battery to spare! So, easily 9 hrs SoT...
