25 min cost 27% battery

I unplugged the phone and got onto the bus. I read news with Captivate. Nothing fancy, just NY Times, Fox News etc. I got off the bus later, I only have 73% battery.
Yes, I just started my day and it's only 70% of battery.
#FAIL.

There are a few simple things you can do to increase battery life. Turn the screen brightness down and use a solid black background as a wallpaper. The screen uses the majority of the batter. so dimming the screen helps, when using a black background the amoled display does not light up black pixels so there is power drain.
I've been running on the same charge since 4pm yesterday. I've streamed music through pandora for about an hour while exercising, browsed the xda forums using the XDA App for 30 mins, made a few calls, browsed Facebook for 30 mins, surfed the web for a couple of hours before bed. Its now 10AM and I'm sitting at 36%. Not to bad really! The phone functions exactly the same at 36% as compared to 100%.

I wonder why everyone says to use a solid black background? Do most people use their phones primarily by staring at the home screen? I'm never at my home screen more than perhaps five seconds while switching apps
I've had pretty poor battery life as well, even after discharging, recharging, and deleting batterystats.bin. There are small tips here and there, like black background and screen brightness, but even following them all, my phone lasts me barely ten hours, and most of that time it's idle. For instance, I listened to local must (no streaming) with the screen off for about an hour and lost 10% of my battery life. What's up with that?

I am also shocked and confused by how people can use their phone so heavily.
I already killed those unnecessary processes (e.g., all AT&T crap). I have a static wallpaper. I have screen brightness at 60%. And all I have been doing is just reading news and surfing the web. It literally cost me 1% of battery for every 1 min of use. It's just ridiculous.

You are probably on your home screen a lot more than you realize.
Anyway it's a smartphone, they all eat through battery time. you will never get superb battery life unless you crowbar a 3000mah battery into your device.
edit:
set the screen on its lowest brightness setting, the only time I've had to increase the brightness is when I am outside in the sun.
if you are on a bus, if you are not using wifi, turn off the radio.

You just said your phone is at 36% eighteen hours after charging! Compared to the 0% I'm at ten hours after charging...I'm not looking for superb battery life at all, just somewhat decent. I'm actually bringing a backup feature phone with me to college this semester in case I can't resolve this issue, because I will need to use my phone both in the morning and at night some days

I have Wifi, BT always off. And I don't listen to Pandora.
I think the key is you have the lowest brightness on your phone. It is going to save you a lot of battery 'cause half of the battery is for the screen.
But I just couldn't stand it. I wish I can set to 100% all the time. It looks so much better.

The phone radio is a huge consumer of battery - especially in weak signal areas. The bars are not that accurate either. that coupled with 3rd party apps that don't always behave nice, can equal rapid battery drain.
Putting the plain in Airplane mode is good way to see what battery life is like without the Cell radio always doing its thing. It is not a fix, but it can show that the battery/phone are not broken. There probably can be improvements and tweaks made by samsung, but I don't think the phones are defective.

This is what you would call a trade-off I like the bright screen also but I like having longer battery life more.
The screen is still pretty bright on it lowest setting and you gt used to the lower brightness after a while.

how are you using your phone? What apps are you running, are you using any emulators.

There's an app called Spare Parts, which will show you what is using your battery when the screen is off. Open it up and choose "Partial Wake Usage" from the drop down to see.
My Captivate appeared to drain battery very quickly, but with moderate to decent usage throughout a day I was trying to kill the battery it lasted me over 13 hours. I think it's a matter of the battery reporting taking a good while to calibrate properly.

I've had an issue twice now with absurd battery usage. Both times I charged the phone to full and disconnected it; after doing that the phone would lose 10% charge every hour sitting completely idle! Using the phone during that time drained it even faster. Both times powering the phone completely off and back on resolved the issue.

In AMOLED, black pixels dont use power. This is different from LCD where even black pixels still use power.

Have you guys tried fully charging, then fully discharing then repeating this step 3 more times? It helps with the battery life tremendously.

You gotta do a factory reset. Many people as well as myself had the same issue. For me, a side effect was also that the att start up swoosh was stupidly loud.

I only did the discharge thing once, last week, and today I am going on a 21 hours with 28% left.

2g app
I was told there is a 2g / 3g application. Has anyone tried this? Apparently it puts the phone in 2g when no data connection is needed and then updates to 3g when a data process is required...

i'm on day two of not charging mine... and i'm at 25%...
i unplugged it from a full charge yesterday (monday) morning before i left for work and today (29 hours later) i'm at 25%... this is with advanced task killer auto killing tasks when screen is off as well as being aggressive about it. i've been listening to music from my sd card, browsing facebook and taking some pictures (and uploading them to fb). i guess i'm either super lucky not to have any problems with GPS or the battery, or i'm a very light user.

I dunno what happened to the main battery thread?
I just got a new phone two days ago because of the restart issue. This one has the same battery issue. Drains 2-4%/hour just being idle. I have nothing beyond launcher pro and google voice installed. Everything is on lockdown in terms of batt usage. The only thing I haven't done is turn off the cell antenna.
I've tried the tricks I knew: factory reset, calibration trick. These didn't help at all. My last phone just needed a factory reset and it was all good. Now I'm sad again :-( will it just improve itself when the phone "learns" the battery or something? I wish I could teach it

Several things you can do.
1) Use WiFi if you can use it, it uses less power. If you don't have somewhere to use WiFi, leave it off.
2) Same goes for BT- leave it off if possible.
3) Use this to get rooted and remove all the ATT crap that sucks battery life. Applying the lag fix also means you spend less time with the screen on, so that can also help you out.
4) Use Auto Brightness
5) Disabling haptic feedback and the tapping sounds (I find it more annoying regardless)
6) Use a static black wallpaper- or something really dark. IMO it looks great black and plus the AMOLED... Black doesn't use power.
7) Use Advanced Task Killer. I have mine on Aggressive and Moderate security every half hour. This will make sure hung apps, etc get killed and apps you haven't ran. Make sure you whitelist the apps that run your widgets and such though.
That's the best things to do to.
Edit- above all, remember this is a SMART phone, not a feature phone like the iPhone is. The simple fact this full blown SMART phone can even begin to rival just a feature phone like the iPhone speaks volumes to how much more efficient it is than what you think it is.

I too have had issues with battery life but quickly realized what had been causing the issues, twice it had been snesoid not closing down all the way after use, and this combined with an app that was hurting battery life (word feud), I realized what my problem was.
I leave the brightness jacked all the way down. I believe the lowest it goes on the stock rom is like 15%, but there are ways to go lower than that.
I've not used my phone much the past two days since charging it, and i'm currently down to 35%, but most of my battery use is cell standby, with display being 3rd or so on the list.
You can always use a program like tasker to make the phone go into airport mode between certain hours of the day (IE: while you're sleeping) to help conserve the battery life.
There are also tons of other good tips in this thread.
And trust me, the phone can last; i've managed 3days on one charge

Battery life is surprising me lately.

My battery has been doing really good lately actually. It makes me feel good when people are like ah i need to charge my phone and i look and i still have around 80% and by the end of the day i still have around 50 or sometimes 60%. My old G1 would be at around 20 by the end of the day. Just thought i would share something positive amidst all the negativity
Sent from my captivate so excuse the spelling mistakes

Add me to that list. Ive been doing some tweaking to see how much battery life I can get . Just checked and after 8 hrs unplug time Im at 94%

what roms/tweaks have you done? how have you used your phone?

1. all black background
2. disabled syncing and background data
3. disabled gps
4. disabled sound and haptic feedback
5. launcher pro tweaks (less smooth animations)
6. threw it on airplane mode while i sat in class
7. eclair. i hear custom roms are huge battery drainers
8. brightness on lowest all the time (disable smart brightness option)
battery performance while on standby is surprisingly good. sure these settings may not allow you to get the most out of your phone but if you are ever in a situation where you have to get absolutely the most life out of your phone you know what to do.

I'm currently on a stock ROM after some trouble flashing something else i just went back to stock with ODIN, im too lazy to reroot right now haha, pretty much i just have GPS off, disable syncing, darker backgrounds, I use the Dark XDA theme,i turn Wifi on when i'm home but other than that i have it off. I', just using the stock launcher, turned off all screen animations- it makes everything seem faster- and thats about it that i can think of right now. i use my phone pretty moderate to heavily on a daily basis. mostly for texting and browsing the internet. I also play a few games here and there when i get bored. Hope this helps

I have found the battery life to reasonable on the phone unless I am using it heavily. For example, today I have had it on for almost 15 hours and still have 58% battery left. This is with background data on, monitoring 5 e-mail accounts, some FB usage, some browser usage, a few phone calls, screen brightness set to medium most of the time, some music player usage, and WiFi set to on all day. I very often during the day unlock the phone and sync my e-mail manually for one of my accounts as it is iffy on retrieving and I have been waiting for something to come in.
ONE THING I HAVE NOTICED TO DRAIN: I have had this issue a couple of times. I am running stock, and when I have experienced unusual battery drain it has been down to the same thing each time. The SnsService has been stuck 'restarting' under the running services list. Stopping the service has returned the battery life to where it should be for me (for example yesterday I was down to 50% battery after about 6 hours with virtually no use. Checked SNS and it was as described above, and stopping it brought the battery life back in line to usual for me).
I typically with light to moderate use get around 24 - 36 hours, but I usually recharge each night anyway.

same here
i even have a spare battery and i rarely use it.

if u disable 3g battery life can last u as long as 3-4 days, only if the captivate has that capability to go 2g with a tap of a button

[Q] Batt consumption after OTA update

Did anyone notice a change in battery consumption after the ota update?
Before the update I was getting to 97 percent after about 3 hours of the phone in idle - almost no use at all, no WiFi.
now It got to 94 percent with the same usage apart from 3 photos taken, could be that i'm just too harsh about it.. but still - wanted to check if anyone noticed anything.
edit: also I forgot to mention that I added the "mail" widget to one of the home screens, could be the power taker?

Probably the mail widget and the picture shooting (takes much ressources).
I haven't noticed any increased battery consumption, but it is probably to soon to tell.

Also forgot to mention I added two 'folder organizer' widgets , two folders which contain apps and games.
tomorrow I'll start off by removing them + the email widget and see if there is a difference.

are u really lookin' after for a 3% change in a 3h time ? maaan ... this could be a simple measure problem ... dont it take it too serious. if ya want to test it, maki it at least 10-20h run in standby (airplane mode on) ... it doesn't that accurate.

Yeh yeh I know I know I'm exaggerating.. I'm just becoming insane when it comes to battery life for some reason.. guess it's still the HD2's influence
It shouldn't bother me that much as it is.. I have a charger in my car plus I'm almost never gone more than 9 hours from home, which should be more than enough for the batt to last.. call me crazy it just occupies my mind

Update: strangest thing.... I just checked the phone, didnt turn the screen on since exactly one hour ago, batt was at 83 percent... that's about 9 percent in one hour!!!
removed the folder organizer folders, rebooted the phone, and suddenly received sms messages I should have received last night
now that's becoming something I should put my eye on.......

Update -
Well after another hour, phone only dropped 1 percent, i'll try to isolate the problem by adding the folder organizer widgets back and check in in one hour to see what the batt has to say..
If it'll drop 1-2 percent I guess there was some glitch causing the phone to not get calls\sms's and drop the batt usage about 10% in one hour..
Another thing I'm going to do is let it drain until it turns itself off and then fully charge it, I'v heard you should do that like 5 times when getting a new phone.

Update - 1 percent after another hour + folder organizer folders.. so, guess it was some major batt\radio glitch since last night until i rebooted today (phone was on charge all night)

I noticed that the setting 'Best WiFi performance' adds a serious battery drain when enabled after installing the FOTA, I was loosing 8-9% an hour compared to 3-4% before the update. Disabling this brought me back to 2-3% an hour. I still have a way better WiFi-connectivity compared to before the FOTA with this setting disabled.

I actually never checked that option but yeh I get your point, all is ok now I'll update if anything weird will happen, i'm getting 1-2% an hour

I charged mine up the night before last and have used it for internet, Angry Birds, whilst waiting for my clients and a lot of texting and about 10 mins of calls. This morning It's at 60% as I post this. I've noticed a huge difference since the upgrade and the phone is nowhere near as hot since the upgrade either.

It was a glitch 100%..
yesterday I let the phone drain itself (1day 7 hours - after the incident with the battery gone down 20 percent in 2 hours) then I fully charged it, turned it on last night before went to sleep, phone has been on since last night approx' 12 hours now - gone to 97 percent!! this is awesome!! I'm gonna' let it drain again a couple more times and this all over again

Battery lasts for approx 11-13 hours. Loosing 8-10% each hour with no usage at all.
It is updated. Reset to factory defaults. No extra apps installed. Just gmail, htc hub sync, wifi and that kind of stuff. No friends stream or Facebook or twitter.
What should I do? This is totally unacceptable.
Anyone tried to send it to service for fix?

first of all let the battery drain itself and let the phone shut down on its own, then fully charge the battery while the phone is off, do this for 3-4 times it will increase the battery's life span and charge time.
also check for the "best WIFI performance" as described in my post above, if it's checked uncheck it.
use auto screen brightness.
most important of all and may be causing your issue - check the stats of your charger, the charger I got with my sensation is imho faulty, it makes electricity noises, so I went back to my old HD2 one - perfect - the most important thing to check in your charger is the output voltages - it has to read 5v---1a - nothing different.

I think its better not to use auto screen brightness but use a fixed setting (maybe at around 25-30% brightness level). The reason being, the processor will have to be worked upon constantly to find the optimum brightness level and that would consume power!

Personally I believe the process of identifying the lighting and adapting to it doesn't take much effort from the processor, and based on my phone - the screen does consume energy but it will last 48 hours with the auto brightness setting on so why not use it? it's one of the good options we have in our phones and i really like it that when i go outside to the sun it'll increase the brightness in a millisecond.
the guy from the post above that's getting 10 hours of usage has a problem that I don't believe has something to do with his screen brightness unless he keeps the screen turned on all the time....

I updated to 1.35.xxx.x in the morning and after that the battery meter has only gone down by about 20% in the last 7 hours or so! The phone was off charge in the morning and I downloaded the update over my 2G connection. I also put on a live wallpaper just for fun! No calls made/received but few texts only. No games played. Surfed a little bit on internet (maybe 10 mins).
I'm liking it

Fast discharging

I896, Rooted, factory Gingerbread.
I have a Captivate and a Tab. Both Wifi only, no Sims, Airplane mode on, Bluetooth off. Machines are on but screen is off. The Tab looses 3% over the course of the morning and the Captivate looses 20%!
I'm running regular 'power user' type apps; Titanium Backup, Tasker, LauncherPro. If there are any apps notorious for secret batt consumption, let me know what to avoid.
Running SystemPanel Lite - I can't see any app that is taking up more CPU time than normal that would explain this kind of drain. The battery page shows a good proportion of battery use display and wifi. In one instance I used the Captivate so little that display showed less use than wifi. In the course of just checking phone power consumption, the display use percent way up, just like expected (Just to show that wifi was really doing almost nothing) and still I had lost more than 15% of battery over the time when the phone was supposedly idle, not connected to anything with the screen off. Some ghost is sucking the life out of my battery. Grrrr. What could it be?
I loose 30% in a night with wifi off, backlight set to absolute min and nothing runninng or syncing.
I don't get it. Any ideas? What do I try next?

His tab is running Android too.
If you don't have anything helpful (or knowledgeable) to say don't say anything.
Op, download watchdog from the market, (system panel is kinda ..meh.) and see if there us a rogue app munching battery.
You may consider flashing a ROM see if its just that firmware/kernel reacting to your phone.

Have you tried Juice Defender?
Also, check to make sure you don't have applications constantly running. What version of android are you running? Check in system settings -> status -> somewhere in here you can check the battery status and what applications are pulling the most juice ... From there if one application needs to be removed you can action it ...

Also try the "Battery Calibration" app in the market. It's free.

my captivate running cm7 STOCK will drain down to 20% from being idle for 12 hours
my battery will also drain 30% from 45 mins of wifi only use.
doesnt help him but thats my experience from my captivate

Menu -> Settings -> Wireless and Networking -> Wi-Fi settinngs -> Menu -> Advanced -> Wi-Fi sleep policy
Set it to when screen turns off.
We have to switch that every time we flash. I really wish it was default. Some ROMs also have background data control, but it's usually when wi-fi is on so it shouldn't be a problem.

You do know that cm7 doesn't have the proper hardware drivers from Samsung so the battery life is known to be HORRIBLE right? If not you should really read up on the ROM you're using
Flash any touchwiz ROM, especially a native I897 build and you will see a dramatic increase in battery life.

I'm on CM7 and am going on 27 hours with moderate usage.. Granted, I have the 1800 mah battery from the Sprint Galaxy S2

trying flashing to pinnacle. I too have battled weird captivate drain issues.
if you wanna try CM, read my thread:
http://forum.xda-developers.com/showthread.php?t=1364357

I've held off replying as I was trying a few things and figured I would report only once I was done.
I found and ran Battery Calibration, just before I read the post. Between that and turning Wifi sleep policy to off with screen off, I had a great weekend. I was getting a day and a half out of my phone, which considering the use, was very acceptable. I was getting about the same drain as my Tab. I had 1% battery drain after 4 hrs of screen off time. That seemed fine for me.
I got back to school where I teach and yesterday the phone drained as fast as it has before. Interestingly, it continued its rapid drain even after I left the school and went back home. So, it died at 4am this morning. I heard it shut down. The school has at least 4 routers, two of which have 5k access options. I know if I choose them, my laptop drains way faster. Is there a way to limit my wifi connection on the captivate and not use the faster 5k connection?
But, this still doesn't explain why, even after I leave the school, the Captivate continues to drain when it is 10ft from a single 100mb wifi router.
I'm almost ready to try a custom Rom, but not sure how that will affect my ability to use it as a phone, once I get my Sim activated. Still new to this all.

You think everyone running a custom ROM doesn't use the phone?
Shouldn't affect your ability to do anything...

The WiFi and cell radio do increase power on lower signal as we know, but that's not always the cause of drain. I remember times using Froyo when kswapd goes nuts for no reason, or trillian, email, twitter or some other app just starts using massive CPU. Many apps are probably never tested on a system that has no connection most of the time. That's where all the utilities come in handy to find the culpret. OSMonitor can help find CPU hogs. TiBu can freeze apps, or uninstall them temporarily. Juice Plotter can monitor drain over time (newer Androids have something like it built-in). It takes some time to find it, but newer versions of the OS make it easier and have less trouble.
Also the battery % is only estimated. I'd trust full to empty time rather than 90% to 80% time as 10% use since it's not really as linear as we think.

Not to point out the obvious, but it can be the battery itself that has the problem. They aren't exactly manufactured to NASA standards... well, maybe their standards lately, but the point is, sometimes the ghost you're chasing is staring you right in the face.

Marshmellow Upgrade | Awful Battery Life

Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.

Battery life is relatively unchanged in mine after the mm update. Easily make it through the entire day with 50-60% battery life remaining. I disabled a whole bunch of the bloatware (and will be removing it entirely when I decide to root my phone) and battery life is wonderful.

Mine has been fine, slightly better with doze/disabling packages. Do a back up through Smart Switch and try a factory reset. I do that every time I update.

I'm envious of your successes. I'll give it a bit to see if it stabilizes, if not I'll use SS and reset/restore.

I will recommend "Package Disabler Pro" to disable bloatware. Costs but is worth the cash.

Mine went through on Thursday and so far battery appears ok.
I have noticed however the lighting is messed up all over. Play books night light feature is broken and dims it to unrecognizable levels. I have to go into the settings again when in the book and disable auto lighting and manually raise it. When back at the list of books screen, the brightness drops to nearly off again.
Also it seems the notifications when listening to music are much louder. I could listen to mp3s via poweramp while reading a book and get an SMS text and itd be a light little sound. this is playing louder than my music and very annoying.

My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

1: Apps/sync will use mobile data as priority if this is done while waiting to connect to wifi. In turn, using even more battery if an app/sync wakes the phone switching between networks.
2: This is damaging to Li batteries. To extend the life of your battery, it is better to keep it topped above 80% and cool(not very common in real world applications). These aren't Ni batteries, long gone are the days of "memory discharging".
If you don't need notifications at night, use airplane mode. I miss Xposed, Autotasker, and Amplify(formerly Bounce)... Greenify is a good alt atm
Note: Sometimes even Play service updates will introduce bugs and or "retarded" policies that will destroy the battery, especially the "Now" systems. It can happen at the most random times as well and not at all most. Every now and then the fat man will get stuck in the tube.

All thoughtful replies. I don't have Location on ever, unless I'm using Waze, so that's a non-issue for me. Allowing WiFi to sleep when the phone is off, while I'm only connecting via WiFi, effectively makes my smartphone a dumb phone, until I wake it up, right? The fact that I need to start changing around "normal" settings on my phone, to lesser benefiting ones, to get back to the battery life I had before I installed MM is pretty silly. I've been hoping things would settle down, but they don't. I can try using SmartSwitch later to see if that helps.

No, it will connect LTE and then switch to wifi. LTE use more battery life, the network switch uses a bit, then finally you are into wifi. If your phone wakelocks or alarms(location ping, play service ping, etc) it will use more battery than wifi always on. Personally, I've tested both to make sure a wifi wakelock bug hasn't been introduced as I do with every update and play service update(it does happen and it's horrible drain). I see more savings always on.
If you meant you disable mobile network, yes, dumb phone, text and call. Also, I disable mobile usually always as I piggyback off work cell at work, and always wifi at home. I only toggle mobile data when necessary.

My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

I believe this is what most people encounter. Most dont have unlimited data and use WIFI always. I think by default, WIFI is set to always on, even when phone screen is off. WIFI will rape your battery. I did my own tests with wifi vs 4g and just by using my 4g all the time, battery quadrupled. Many argued that WIFI uses less battery, and i have the best of the best wifi router/modem/isp with 5ghz ac excellent coverage. Not the case for me. I have unlimited and just stick with that now. Battery life on MM has been great for me.

My battery life is 4x better. I couldn't be happier.

Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.

Been on MM for about five days now and my battery blows, so much worse than what it was!

Mine is exactly 4 times worse

Battery the same.
But I have to tap the screen harder to chose app.
Going to factory reset and start clean, been a while.

Not that I know of.
Though they JUST released Marshmallow. Verizon is probably still patting themselves on the back even though they released several months late. What I'm waiting for is a miraculous root.

I never use my phone the same amount every day, so it's hard to say exactly what kind of battery life I get, but I have noticed that it has improved. I would usually be near 15% by 10pm after coming off charger at 6am. Now I float around 25% at 10pm. So it seems to be better, even if only slightly so.

I see a minimal improvement, but I was doing what I could without root prior to sleep unnecessary crap.

Weird, when thye MM updated happened, up until the last two days, I was getting much better battery life under MM. But the past few days my battery life has declined dramatically to the point that I am not getting through a day of minimal use. Screen only 2%, Android OS consuming 76%.
I just fiddled with settings (Changed Wifi sleep to While Charging; Turned off wifi scanning). I am going to also try a reboot to see if that helps. I swear it started just about the time I started looking at Nexus 6p replacements).
Update, rebooting, and removing a few more useless apps and battery life has returned.
