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
Hello,
Gear S2 is here for about a year - what is the battery experience?
For example, someone charging the battery every day for a year - do you experience battery capacity drop?
My coworker owns Moto - after about a year of daily charging the battery lost most of its capacity making the watch unusable.
Does Samsung put better batteries?
I bought S3 recently and hope for a good news...
I have had my watch for over a year. Gear S2 classic non 3G. I charge it at night and use it all day and it is still at 60 to 70% I haven't noticed any real drop in the battery capacity
Same here. Not noticeable degradation after a year.
I received mine for Christmas 2015 and been wearing it every day since.
In fact, with the firmware upgrades, it may be better than when I first received. I do keep my brightness at 3, Always On, and Bluetooth only. No Wifi, no NFC.
I can get around 2 full days with a charge, but it takes some settings tweaking to get it. Normal stock settings, I'm lucky for 18 hours. Worse if I am running an overly elaborate watch face.
I enable Do Not Disturb when sleeping.
Delete Running widgets that you don't use (steps, heart rate, water /caffeine), stuff like that.
On the Gear Manager, go in and modify what notifications you receive on your gear.
Maybe it's just me, but it seems the more apps that send notifications, it drains both my gear and S7 battery faster.
I also like to look in the information screen, and look at the Memory Usage. CPU / Memory hogs will show there.

I have big concerns of consumption of battery with this application
Am I the only one?
You have can be trick?
Thank you
Some watch faces are too bright or consume too much battery in their always-on state. Try a watch face that has a dimmer always-on state, or take your favourite watch faces, and change their always-on state to have higher opacity.
I made a dial I same, quite black
I am going to try a reset of the watch, seen that nobody confirms me the same problem
I use this app(watchmaker) and consumption with always on display is approximately 25/30 % per day.
Wifi is switched off , Bluetooth used when needed.

Either some functionality on your watch is disabled or something is wrong here. No way, watchmaker can beat stock watchface. I loose 45-55 percent a day with stock gear dashboard watchface. AOD, wake-up gesture, shealth features and bluetooth on. Wifi auto. NFC, bt connection notifications off. Using GPS occasionally. Without AOD i can easily get 3 and a half day. I've never saw anyone claim to can get more than 2 days with AOD on on the forum before, so this is really confusing.
You can believe or not, but for me the battery consumption with watchmaker is lower than with stock Watchface. it is also true that some Watchface consume a little more, but we are talking about up to 10% more per day, i start to use Watch at 10am and remove Watch at 23pm,all' shealt notification on,wifi off,gps off, Bluetooth when needed,AOD always on,screen brightness 7. When use stock Watchface i lose 45/55% of battery per day.
I think I may have worked out what is going wrong, perhaps one of the developers can confirm,
under ‘my watches’ I have a number of other whatchfaces that I have downloaded, these aren’t selected on my watch but are there as an option, where as the chosen one only has basic functions, the others all have fancy meters, data sourcing apps - after deleting these from my phone and checking they are not available for selection on my watch the battery life seems to be normal, I wonder if the other watch faces are in some way working in the background and therefore draining the power even though I am not actually viewing them
It is Wi-fi connection what drains LOT of power. Be sure it is turned off when not in use to keep your power as long as possible.
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...
