[Q] Horrible Battery Life on my Captivate - Captivate Q&A, Help & Troubleshooting

hey guys, having troubles with my cappy here. running CyanogenMod RC1 rom. i needed to use my GPS this morning, used it for navigation for about 15 minutes and turned it off. from 7:30 AM this morning when i woke up and unplugged my phone, it's already down to 7% battery left. when i turned off my GPS it was at 56%, that was 9:30ish. so from 9:30 - 12:15ish, it's down from 56% to 7%
that is without any apps running, wallpaper disable, it's been sitting in my pocket sleeping
is there a way i can undervolt it? i know you need a compatible kernel, is there a compatible kernel for CM7 RC1 than i can load so i can UV?
any help appreciated, thanks

Bad battery is one of the known bugs in CM/MIUI. Right now, it's a fact of life every CM/MIUI user deals with.

hm that's a bummer, i'm loving CM7, but now i've got to resort the old fashioned way to find my way back, as my phone is now dead, rofl
gonna have to stop and ask for directions lol
so, is there a kernel i could load that would allow me to undervolt my cappy with CM7?

You know, nothing about CM7 is a batt hog IMO. Only weird thing I can find is that my voice calls use about 27 percent of my battery per hour. I've tried flashing different modems and all, but it could also be that I have a year old battery.

I've been reading on this as well and followed this thread.

Was a great help doing the jump charge as I was flashing many ROM/kernels. Hope it helps you too.

What's eating up the battery? If its the OS at like 40% I'd do the following
1. Shutoff GPS
2. Wifi sleep policy to when screen turns off
3. Determine which apps are keeping the phone awake(use spare parts)
4. I've been using jk4 modem, as far as I know because the developers don't have the Samsung source code there is a problem with the modem that will keep the phone waking
5. Run the battery down to 20%, plug phone in, power off, because of the source code it'll reboot immediately and you'll have around 46%, let charge to 100% unplug, that always eliminates my wake problem so I repeat the process every time my phone stays awake and let it chrage overnight afterwards and I've been getting between 1 and 2% battery drain/hour

Just manually force close battery eating apps. In manage apps. ( not running apps) cm7 doesn't have the closed sauce needed to improve its batt Life just yet. Only use data or wifi when needed. GPS when needed. Turn off auto sync. Turn off location. Anything that runs constant that you don't need. You can get an app autostarts, people have suggested it working for them.
For kernels there are three awesome ones: escapist, tkglitch or platypus neo10
Please read through their OP before playing with them. good luck

Captivate Battery Issue Investigation

I am starting this thread so folks that are having batery life issues on their Captiates can post their findings.
Captivate users are getting mixed battery life with the stock and custom ROMs. Let's see if we can't get the problem narrowed down. Whether it's an issue with Battery Stats or possible a bad batch of batteries, whatever the case let's get this settled and resolved once and for all.
When posting, please include some basics about your device. We all know it's a Captivate, this is the Captivate forum, duh! But let's include ROM name, if custom, use STOCK for Stock. Date stamp on your battery, any custom apps and your basic settings.
Let's narrow this down.
Thanks.

Prsonally I am running Cognition 2.2 Beta 7. Have had the same problem with all prior ROMs as well as stock.
Have tried completely draining, recharging with device off, reset battery stats. No luck, same result. I leave the house at 5:30a, am down to 70% by the time I get to work. By 5:00p it's dead if I don't plug it in.
My next step is to try buying a new battery. See if that helps.
Anyone have any other ideas?

I have used the idea of draining battery completely and then plugging it in and letting it charge overnight powered off. Worked great for me.

I tried that, no luck for me.
I had the same issue earlier.
I noticed that my battery life came back to normal once I stopped using ADW and disabled automatic sync for my corporate (exchange ) email account in @email.
(I am currently using TW Launcher with Cognition 2.2 Beta 6).
I can get on avg. 12-18hrs of battery life... with light use.
For my everyday typical type of usage? About 10hrs with moderate usage.
But.. let's say I'm stuck in a waiting room somewhere for a few hours? With heavy use - even with the screen dimmed - I can get 4hrs out of the device.
Bottom line.. no matter how hard I tweak this thing - the display just eats the battery like a fat kid at an all-you-can-eat buffet. So I just keep it hooked up whenever I'm at a computer... which is my job so quite a bit
My first captivate stock, I was easily getting 18-24 hours.
After having it replaced with another one, I'm getting less than 8 hours.
The only differences is that the second one was updated to JH7 using Samsung Kies

Hi mate I have a galaxy s I used to get a days usage from the battery with heavy usage so I bought a 3000mah expanded one from Amazon.co.uk i haven't completely set the battery up yet it has only had one full charge and one full discharge but it lasts two days now with heavy usage games, movies and allot of web and app browsing maybe you should try one.
The battery comes with a new back cover and obviously makes the phone fatter but it is easier to hold and not really that heavy.

It's all in the screen usage. I'm also using setCPU which helps the standby time significantly.
I have gotten a full 21 hours on this phone. But that is with probably what most would consider light usage. Maybe a few texts, some checking via XDA app, updating Facebook, playing a few games for about 30 minutes, but then when I sleep, I leave it unplugged, but turn off Wifi/Mobile Data and Autosync. When I'm at work, I leave those on. My display is always set to auto brightness, with the time out at 15 seconds.
Running Cognition 2.2 Beta 7 and I don't seem to have a dat of manufacture on these eBay batteries. My stock one is at work, so when I get there tonight, I'll update this post.
But like someone else said, I think it's all within the idea of what one calls moderate use. If I am using my phone a lot, the life goes does dramatically. My phone probably sits more than it is used, therefore that's why my battery life is so long. I'm happy with a baseline of 8-10 hours on this, since I have multiple opportunities to either plug it in, or switch to a fresh battery.
Could someone plz share ur batterystat file?
By bettery life is BAD now..
It goes down like crazy..
And fully charged in 6 hours from 0%.
I sun think this is normal status..
I tried everything but still the same..
Wanna try to copy someone's stat file to see how that works for me.

Battery drains quickly

Not sure if this is a problem with the captivate (Rogers I897) or if it's just a select few, but I noticed last night despite the usb charger being plugged in overnight, once the battery reported full, it stopped charging.
So basically, I got home from work, plugged in my captivate because the battery was rather low (only takes 24 hours of maybe 30 mins to 1h of actual usage before I get below 40%), and it took 4-5 hours to charge completely. When I unplugged it in the morning though, it was already down to 64% with just being idle all night.
So is this normal or should I ask for a replacement battery or something?
There are a lot of posts around here about batterirs dying quickly, and "charge death", but I'm not really sure whats going on with your phone. All I can suggest is that you make sure that you close all apps and stuff before letting it idle, and just see how that goes. I suppose you could just have a bad battery. Are you on a custom ROM or stock? I had problems with battery life when I first flashed to a custom rom, but since then I've switched to serendipity 4.3, I have it undervolted, I keep an eye out with a task manager, and my phone has no problems lasting all day, even while texting a good amount/using it for searches and stuff.
What ROM are you running?
Did you have GPS/Bluetooth/Wireless left on?
There are known issues with certain builds of ROM's causing this issue. If your on a stock ROM and still having this issue? I would take it in to possibly have it warrantied out or at least have the battery replaced.
I haven't ever had an issue with my phone losing a charge while plugged in.
Yeah, stock ROM. I haven't installed any additional task managers, but I usually open it up and kill all tasks when I'm finished with them.
I do keep bluetooth and GPS off at all times, but I leave wifi on overnight because I didn't think the battery would stop charging entirely once it was full. I've only had the phone a week so I could get it replaced, I just wanted to investigate it a bit to see if it's a common issue or not before I did that.

Settings --> Mobile and Network --> Wifi Settings --> Advanced (soft key) --> When screen turns off
This would turn off wifi after 15 mins of inactivity. This would help save ur battery.
And yes, charge does get cut off when left for extended times, but not right after it says charge full.
Recalibrate your battery/battery stats. This is my method, there are many others though:
1. Charge the phone with the phone ON, until the phone indicates full battery
2. Unplug the charger, replug, continue charging until full battery again (I repeat this 2-3 times)
3. Turn off phone, charge until full battery
4. Unplug the charger, replug, continue charing until full battery again (Again, I repeat 2-3 times)
5. Turn on the phone, let the phone charge yet again.
6. Boot into Android Recovery, delete battery stats (Advance -> Wipe Battery Stats)

Cool, I'll try this, thanks!
By default, wifi does get turned off when the screen goes dark and I haven't changed it.
I've also been tring to flash to a new ROM (been trying Android 2.2), but Kies won't load my phone). I think I'll research other methods when I have time.

If u r not heavy on data and use it for things like mails and chats, and esp when in an area with no proper 3G coverage, u can switch to EDGE and get out of 3G. 3G sucks more battery compared to EDGE.
So I wasn't able to complete all the steps to kind of fix the battery problem, but I plugged it in to almost 100% (I think it was like 98% or something, I had to go out so I had to unplug it), but when I got back I plugged it in again and let it charge overnight. This morning however, it was still at 100%, and now, about 8.5 hours later, it's only at 73% so I think maybe it just had to normalize it.

Give it some time to normalize. And charge showing 98% when unplugged at 100% is normal.
And yes, seeing 60% battery left after an hour of calls and tasks involving an hour plus of display on after a day's work, apart from push emails, etc (~14 hours standby) isn't so new anymore to me.
Stop watching the battery so closely for about a week and u'll be all set
I was on darkys 8.1 rom with jk4 modem, calibrated the battery one time and I went 18 hours. Starting from 98%
6 hours were phone calls, 1.5 hours of text messaging. 2 hours of power amp . The rest was pretty much just standby/idle time.
Though, I don't get that anymore though.. Jk4 has gone to **** for me. I used to get full signal majority of the time, and for places where other people go no bars, I got one or two. Now its pretty horrible it makes me sad ;(

[Q] Captivate Battery and Serendipity

Hi folks.
Sorry if this is a redundant question or thread, I have used the search feature and am not getting the results I want. Furthermore I have a 2 year old and 9 month old hanging on my legs here and just need an answer so again apologies if this is redundant.
I have had my Captivate for about 5 days now. I rooted it and installed Serendipity 5.3 ROM. Today I noticed my battery went from 100% to 5% in 4 hours. Is this normal?
I got home and updated Serendipity to 5.4 and then 5.5 but not sure if that will fix the battery issue. The day before I ran the battery all day 10 hours and I was at 35% which to me was normal as my iPhone 4 had the same performance. But 100-5% in 4 hours seems a bit strange.
Any help would be appreciated sorry for the long post I need to get back to my kids.
Thanks!
4 hours for almost 100% battery usage is not normal.
check your wifi setting, gps setting first.
Sounds to me like your battery needs a calibration. It's generally a good idea to re-calibrate your battery after flashing. I generally get 20hrs on my Captivate with Serendipity 5.2 with average usage.

Now that one kid is asleep and the other on her way....what is the optimal wi-fi setting for best battery life and the same for gps?
Also, I looked at that thread and I am in process of trying it out integrasaurus.
This is my first time with an Android phone, I came from an iPhone 4 jailbroken so I am an Android virgin and 5 days old.
I also want to say I am sorry about starting a thread if this topic was hit on already. I have been around forums a long time and I know how frustrating it is when noobs do these things so I thought I'd offer my sincerest apologies for doing what I would get mad at too.
usually after you flash a new rom, the gps is set to on. turn it off if you are not using it;
go to settings->wireless and network->wi-fi settings, then click menu to bring up the advanced->in the wi-fi sleep policy->make sure select "when screen turns off";
go to settings->applications->samsung apps->make sure it is "off"

Hmmm
I dont see this?

I got the wi-fi taken care of though thanks for that.
It was strange today though, I plugged the phone in to wall ac and it took forever (5hours) to charge from 5% to 40% and then drained in less than an hour back to 5%.
Its charging now and has been on my usb port for 2 hours and its up to 72% from 4%.
That was also a confusing mystery.
Hey guys, just want to say thanks again. I'm still working on calibrating batt but I after reading some more in the forums (kids finally both in bed and OUT) I discovered that I had 2 task killers installed and that these apps are battery killers (at least in some opinions).
I uninstalled them and charging seems to be moving faster than before. I will let you know how things go.
Thanks again!
I am running Serendipity 5.5 and my battery typically lasts between 26-30 hours with normal use. I don't use any task killers, but if you have your task killers set to be too aggressive I'm sure that would drain the battery pretty fast. I'd suggest just ditching them completely though, as I get over a day's battery without trying to manage all of that.
Also, check if ur gallery has the sensor bug. U can find this out under battery usage using the SPARE PARTS app.

yup, I deleted them already. I believe that was the cause of the sudden change in life, as I didnt have many problems before them.
After my battery cal I have been running the phone on and off normal use for over an hour. Battery is now at 95%, started at 100%.
I see improvements already, but will hold off saying its fixed completely until I can give it a day or two of testing.

sometimes the thumnails get corrupt which eats battery while trying to load and need to be "refreshed" a simple way to do this is in the app SGS TOOLS run the script "clean_thumb_db.txt" this should fix gallery issues.
Thanks for this info. This will be something I will keep an eye on for sure. Phone is still above 90% after over 2 hours. Hoping the calibration and deletion of task killers did the trick.

Charge battery 100% then some... Power off phone and let charge longer... Boot into Clockwork and reset battery stats.... Run the phone a few charges and you should be gold.... Under normal/light use I can get 1.5 days out of my battery...
Also check your wireless settings. Try setting them to turn off wireless when the screen is off. That was a huge battery drain for me.
Thanks to all here for the help and thoughts.
So last night I
1. Got rid of task killers
2. Updated Serendipity from 5.3 to 5.5
3. Adjusted wireless settings
4. Calibrated battery
I finished all this at 8:15pm CST and the phone has been unplugged since then, with moderate use between 8:15 and 10:15pm. It is now 7am CST and the phone is at 63% power which is a huge improvement from yesterday.
I am convinced it was the task killers that had the most drain on the battery.
I will give it one or two more days and see how performance is then and let you know.
You guys rock!
Back on Serendipity 4.3, while OC/UVing I could get about 25-28 hours with normal use, texting throughout the day, occasional calls.
Now that I'm on 5.5, I am getting about 28-32 hours, still OC/UVing.
Also, I use advanced task manager, and it doesn't kill my battery at all. Any more than other apps at least.
Glad everything is working out for you iDroidd!
..Now back to flashing lol.

[Q] My Battery is suicidal please help.:)

ok so i own the sprint htc hero obviously and i keep switching between plain cm6 and blackmod every few months or so. For my Kernel i use
Decad3nce-DecaFuct #589 691mhz CFS stable
i keep it clocked at 245-691 with collins battery tweak
i charge my phone to 100% and then unplug it. screen off, gps, mobile data, sync, bluetooth, 3g, everything is off. brightness is as low as it can go. so im doing everything i can to save battery power. if i leave it in my pocket all day it CAN last about8 hours....that being said at that point its basically a brick. however if i turn anything on obviously it dies faster. if im online for 45 min my phone will die. a five minute youtube video costs me 32% of my battery. there is no way that my phone should be acting this way and im out of ideas. i have tried switching roms, wiping battery stats, running through battery cycles reverting back to stock via the RUU nothing works.
PLease if you wonderful people have any ideas *PLEASE* help me with this.....
Well you could try running a more current rom like CM7 or Aosp's CM7 GingerBread. Also you could try running your roms without the Collins battery tweak. You could try using dec's battery tweak if you prefer to use one. You could try calibrating your battery. Just a few things you could try that might help.
Edit: Also do you have an on screen off screen profile set with the battery tweak???

i have tried cm7 and still had the same issue. and i am partial to the battery tweaks because setcpu and ocwidget seem like they would eat up resources wouldnt they?....i dont think ive heard of decs battery tweak tho....unless you mean the DECAmod one and i thought that was only for 2.1 roms.....maybe i got my facts mixed up tho...i calibrate my battery everytime that i flash a new rom to the phone. as far as i know the version i have does not allow for seperate profiles for screen on screen off.
I had the same problem and out of curiosity i dropped my processor speed from 710 to 576. Yeah its slower but on Aosp/CM7 and with sd-ext done its plenty fast. and with everything on and the phone in my pocket i drop about 4% every hour.

Deca's BattMod will work on CM7/aospCM7. However with CM7 you really don't need it (or anything else to overclock/underclock) as CPU settings are in the ROM itself. In fact, it is recommended that you don't, as they will/could fight with each other.
If properly calibrating the battery (properly is the key word) doesn't get you at least a solid day with moderate use, I would say it's time to look for a new battery. How old is it? Mine is about two years old and I still get about 2 days, stock aospCM7 ROM and kernel, moderate use with ONDEMAND 176/729

I'd still say that 4% an hour, without using the phone is way too much. If your battery is still good, you should be able to get better than that by at least half (2% an hour drop).
I have been up for two hours (unplugged at 6AM, it's now 8:56AM) and am still at 99% and that is with moderate usage (a couple texts, sent and received an email, one 3 minute phone call, some Facebook and XDA).
See ^^ for my settings. Give it a try
My brothers hero would die incredibly fast also no matter what we tried. We ended up RUUing and taking it into sprint. They did a battery test said they didn't know why it died so fast and ordered him a brand new one. He had normal batt life again after that.
So if all else fails try taking it into sprint and see what they tell you.

When you go to the battery usage stats in Settings--About Phone, what does it show you? That may show/tell what is eating up your battery so much.
What is your signal like? Are you in an area with poor signal? If so that could possibly cause the battery drain -- a phone working hard to keep a decent signal eats battery pretty quickly. Consider upgrading to the newest .29 radio baseband (if you're on Sprint) if you haven't already.
Try to check out the battery usage in your Settings and report back what it shows. We may can help you notice anything out of the norm.

Deca's BattMod will work on CM7/aospCM7. However with CM7 you really don't need it (or anything else to overclock/underclock) as CPU settings are in the ROM itself. In fact, it is recommended that you don't, as they will/could fight with each other.
If properly calibrating the battery (properly is the key word) doesn't get you at least a solid day with moderate use, I would say it's time to look for a new battery. How old is it? Mine is about two years old and I still get about 2 days, stock aospCM7 ROM and kernel, moderate use with ONDEMAND 176/729

my phone is about 7 months old. so battery *shouldnt* be crapping out quite yet as battery life on one of these seems to typically be about two years before it starts to crappify.
@MrDowntown12
i thought about that but was worried that the ruu doesnt get it COMPLETELY back to stock. good to know it does and that someone pulled one over on sprint ^_^ if all else fails then ill try this but in all honesty they will prob still charge me $50 and i just dont have it.....
@chromiumleaf
battery usage is:
Display 59%
cell standby 12%
Phone idle 11%
android OS 8%
Media 5%
setcpu 3%
google search 2%
gallery 3d 2%
"top -m 5 -n 1" returns
process id 2337 at 8% and 163 which i believe is the phone itself if im not mistaken is at 5%......everything else is zeros.
also i think my coverage is pretty average. throughout the day i typically have about three bars but my dbm is 80-100 the whole day and im not sure if thats high.
fyi these stats are while doing my battery cycles if it matters. and ive been unplugged for about 25 min and ive dropped from 100 to 91 with doing nothing but checking battery stats and running the terminal for a minute.
Edit: i know that android os is getting more and more popular....do you think its possible that i caught some kind of virus somehow???? the only ones ive seen are in china but is it likely that my phone is infected? also i want to run cm7 but as far as i can tell there really arent any stables out yet just the experimental nightlies and ive tried it and it didnt fix drain *immediately* but maybe after batt cycles? second edit^_^ i apologize i did not know exactly what you meant by signal. after finding THIS
-105 to -100 = Really bad
-99 to -90 = Not great
-89 to -80 = Pretty good
-79 to -65 = Good
Over -65 = Excellent
i now understand and my dbm hovers at about 88 half the time and the other half it shoots to 97

Ok so if all you were doing in 25 mins was checking battery stats and running the terminal for a little bit, it seems strange that Google Search, Gallery 3d, and Media would have some battery pull on them -- did you even open/use them at all? If not, then it seems like maybe you have some programs running non-stop in the background that are eating your battery even when you're not using them. Try clearing data and cache for any of those in your Settings-->Applications-->Manage Applications menu.
Also, just curious...when you change roms, do you wipe everything (data, dalvik, ext) before flashing to a new one?

I'd still say that 4% an hour, without using the phone is way too much. If your battery is still good, you should be able to get better than that by at least half (2% an hour drop).
I have been up for two hours (unplugged at 6AM, it's now 8:56AM) and am still at 99% and that is with moderate usage (a couple texts, sent and received an email, one 3 minute phone call, some Facebook and XDA).
See ^^ for my settings. Give it a try

I forgot to say that i have music playing through headphones whenever im awake lol, but yeah ill give that a try.
No I had not used any of those. I tried what you suggested and the battery is draining faster T^T. And I always do a full wipe. I wipe data and dalvik reformat my sd and as soon as I her the rom on my phone I go through three battery cycles.
HAHA Solved! for me anyway.
ok so my guess is that its not reading my batts full capacity because i didnt charge fully before one of my flashes. so what i did was:
*charge to full
*run my ruu to revert back to stock
*with phone -ON- charge til green
*power -OFF-
*charge for another two hours
*boot into recovery
*flash like you normally would
*Run through your Battery cycles like normal
since i have done that my battery has been fine. or as good as a battery on a smartphone can be anyway lol

[Q] Blitz - Battery and Freezes

Hey Guys, I've posted in other conversations about bad battery life with blitzkrieg and it seems pretty split down the middle between those who experience good battery life and those who don't. I did follow the advice and wait several days after I re-flashed blitz and my battery has yet to level out. I keep background data off at night when I go to bed, I went to bed with 93% battery left and woke up 7 hours later with a 23% battery life - while the phone was at rest.
I also have a problem about once every two days my phone will freeze up and restart. When it happens it just gets froze on screen and the whole phone vibrates for 20-30 seconds and then restarts.
Has anyone experiences these problems and found a solution to them? Should I change my settings at all?
I really don't want to get an extended battery but with the life my phone is currently getting I don't see much more of an option.
Thanks guys,
The phone freeze/reboot is a known issue with no known resolution. Before I dropped my last phone it had that problem consistently from stock v4 through every variant of the ota updates, revolt roms, gingervolt roms, kennels, scripts, no scripts, blah blah etc.
Now, however, I picked up a second Revo and have run it through gb and flashed gv 1.3, blitz 2.1 and various scripts and tweaks virtually mirroring my old device. I did that Monday morning and haven't had a single instance yet! These guys here do awesome work..
As for the battery draining, I haven't put my extended battery back on this phone yet because I was curious how the stock would perform with these mods. For the first couple days I was discharging at an even 10% an hour. Yesterday and today its dropped to 7.5%. Why? No damn idea. But I can live with that.
So, nothing terribly helpful here but just a disclaimer that your mileage may vary and a nod to the devs here doing kickass work. Good enough that I actively went looking for another Revo instead of fussing with a second line upgrade. That speaks volumes.
Oh yeah I'm not dissing the devs at all they're great!
The revo is a strange device all the reboots due to GPS and airplane mode I'm sure is a hardware fault because every revo I've had has done it and I'm on my third. I love blitz and can't live without my overclock lol I'm just wondering if there's special settings or CPU governors I'm not using that would help.

I've used CPU Master and am on ROM toolbox now. Can't say I've seen a significant difference between the two as far as battery goes. I've used both ondemand and smoothass, same deal.
I did have some luck limiting reboots on my first by bumping up the min to 768 but haven't needed to bother on this phone so its 2 something. No extra settings or anything. : )
Guess it's just the screwy differences in hardware that make some a better build quality than others. Well I said I wouldn't do it, but I lied...
I'm restoring to my GV 1.3 pre-blitz image as I type this. Guess I like battery over performance, we'll see...I may be back to blitz.
Can somebody explain the difference between ondemand and smoothass. I still don't understand them that well. Thanks!
I didn't read the whole thread but seeing profiles for the kernel helps a lot like when my screen is off my phone is set to minimum on the min and max which sometimes causes lag turning on but once the screen comes on it's up and running fine. At that level if I keep the screen off it takes nearly an hour to drop a percent.

Perhaps this is not the best reference but here is one about charging your Lion battery:
This link won't paste:
[URL="http://dottech.org/tipsntricks/17705/tip-condition-your-new-cell-phones-battery-to-make-it-last-longer-but-be-sure-to-condition-it-properly/[/URL]
It points out two possible issue:
1) over discharge (perhaps our meters account for this,
2) getting the battery hot, my phone does warm up setting on the charger, sounds like the usb port charging might be better for the battery?
