TL: DR - Use Rescan Media, win.
So, I think that I've finally found the source of my constant stress regarding the battery life of my beautiful Samsung Captivate SGH-i897.
I know that a good majority of you have just rolled your eyes in disbelief, or just thought to yourself, "Great....another one of these threads".
If it helps one person get their battery life under control, then roll away.
I've had the phone for about 2-3 months and I've been active on these boards since a few days after getting it.
I've recalibrated, done the on / off / on / off trick, battery stats delete, deleted battery info from CWM, tried a second battery, used battery monitors on the phone, turned off wi-fi, turned off auto-synch, turned off bluetooth, lowered display brightness, and everything else I could think of to conserve juice.
Yesterday afternoon, I downloaded OSMonitor from the market in an effort to try another app in a long line of failures.
Nothing seemed out of the ordinary so I was going to give up hope.
While installed, I had clicked on the box to monitor the app in the notification bar.
I noticed that I would have times where the CPU was being maxed but nothing strange was being reported in OSMonitor.
And then it hit me.....
The entire time I'm watching the OSMonitor, I'm being distracted by the media scanner.
It's running over and over and over and over and over.
When the screen shuts off after 30 seconds, it comes back on, the media scanner runs.
When I update something from the market, the media scanner runs.
When I close a program, the media scanner runs.
It is running constantly and maxing my CPU to 100%.
It finishes fairly quickly, (I have 9.4GB / 13GB available on internal and hardly anything used on my 4GB external SD card) but it just KEEPS....ON.....RUNNING.
I do a quick search, stumble upon the .nomedia file trick from XDA archives, and VOILA ! ! ! !
I'm losing about only one half of one percent per hour while it sits on standby, where I would sometimes lose 10-11% per hour, when the phone isn't even being used by me.
I went to bed last night with 48% at around 3:30am.
It is approx. 11 hours later right now.
I've made approx. 8-10 calls, checked my email a few dozen times, and mostly just let the phone sit.
I'm sitting at 39%.
Previous to doing this, I would have lost that amount in one hour.
So, for anyone who has a phone that is losing battery life like it's going out of style, I highly recommend doing the .nomedia fix.
I did mine using ES Explorer and Super Manager.
Go into your root folder and add a file named .nomedia, then go into your external SD folder and do the exact same thing.
If you do not want to do it this way, you can go the easy route and add a program called Rescan Media that does it for you.

Hopefully this helps at least one lost soul, I'm so happy to see my phone behave more along the lines of what my expectations were and not have to be fully charged 2 times per day.
For the record, I've tried the following ROM's for the Cappy:
Perception
Phoenix
Assonance
Darkytt3r's port of Darky's ROM
Stock ROM (ODIN Rooted)
Cognition
And the following kernels:
Glitterballs
SpeedMod
SetiroN
Xcalibur
Will this not cause the media scanner to not pick up anything at all then?
IE no custom ringtones/msg alerts, nothing displayed in gallery, playlists wont work with the music player....
Or will it run media scanner selectively instead of all the time?
The only time I notice media scanner running is after rebooting the phone... yet I'm still only getting about 9-10 hours on a full charge with very conservative use.

So... exactly what did you do to solve the problem? can you describe how do you do the .nomedia fix?? I have exactly the same issue..
Hm, I haven't experienced that bad of a battery drain, but I installed the market app even though it said 2.2... maybe this will make my battery life better! Thanks for the tip.

When you say the media scanner runs when doing all of these actions, does the Media Scanning icon show in the notification bar? If so, then I think it's just an issue with your phone cause I don't think that happens with anyone else's phone.
Unless you are saying that the media scanner runs in the background secretly after every action and there is no icon in the notification bar or anything? If so, I think you can be on to something.

You could just run Media Scanner manually. SwitchPro even gives you a button to initiate it. The only time Media Scanner runs automatically for me is when the phone boots (and probably some other infrequent times that I can't remember) so disabling automatic media scanning isn't much of a loss at all for me.

I'm curious of the same thing. I've only seen the media scanner run when I restart or disconnect my SD card from my computer.

I'll be nice... see the quoted paragraph that was in your quote?
Minlee, no need to quote an entire post, especially when you aren't responding to something in it directly.
As others have said, I only ever see Media Scanning in the Notification bar when I do a reboot. If it runs at other times it is transparent to the phone.
This is probably an issue specific to myself and a few others.
Someone above asked me if I saw a lot of activity in the background or if I actually saw the "Media Scanning" icon pop up in my notification bar.
The answer is that I saw the icon pop up and then watched it scan, over and over and over, all day long, dozens....if not hundreds of times.
That little fix, coupled with the battery calibration that I've done a few times, along with getting rid of some of the resource hogs that run in the background (Do I reeeeally need Google Maps to run 23 hours out of the day???) has given my Captivate new life.

Yeah, I've never seen that kind of behavior. I only see the scanning activity when I first boot and when I do something like take a picture or a screen shot.
So in my glallery, some of my images have doubled, and in my music list for selecting ringstones and such, it has tripled some of the songs, but only one of them works. Mediaserver has 48% percent on my battery drain and its taking more power than my screen is! Anyone know whats up with this?
I'm running AOKPS Alpha 2, but I noticed it was doing it last night when I was still on the Alpha.
I use quicpic for my pictures....no issues

And google play for my music

This is actual issue with the media scanner. From what I've read it's an issue that can happen from a few things. I seem to have fixed it for now, I removed all the media files that were acting up. and it's gone back to it's normal amount of battery usage. I may just format my sdcard, then reinstall the ROM again
Sent from my SGH-I997 using XDA
The day before yesterday I decided to reset/repair the phone from sony companion in an attempt to solve the battery drain (I think due to cell radio standby, shown as the biggest consumer in the power management list) and trying to install one app at a time to figure if app-related.
Right from the start I uninstalled/disabled a few stock apps, including twitter/facebook. I am using however google now, aquamail. As I also suspect spotify to be a huge drainer I didn't install it yet but I am listening to music from sdcard through poweramp.
So yesterday, first day usage, with moderate usage, was heading to almost 6hrs sot which is a big improvement from 3-4 sot before reset, same usage pattern except spotify.
At 40% batt I updated a few apps amongst them sony albums.
The main sdcard is mostly empty since reset. I have kept however the few photos/video and the music folder on external sdcard.
Right after last night update noticed the phone is draining fast even with screen off. Mediaserver shows some cpu time but also keeping the phone awake the whole time.
So i have cleared cache/data of media storage app, rebooted, put a .nomedia file in the music folder. A couple hours later, battery at 80% after 30 min sot, mediaserver is again keeping my phone awake.
I don't see anything else relevant to this issue on forums aside from things I already did, reset with sdcard wipe included.
Any idea what to try next?
Do you have lot of media on your external sd?
Remove your sd and try.
Please ignore my previous post. the mediaserver indexing might just be legit as I found a huge bunch of pics on my external sdcard, probably copied there before reset. All photos sync is off, imagine mediascanner has trouble with that many files. The solution was for me to delete them as really don't need them on device but you might use the .nomedia file trick.
I have cleared media storage data and restart the app, I expect this to solve it, will let you know if that's not the case
Hi, I have a problem with RAM management, or keeping an app running in the background to be more specific. I'm running stock EMUI 4.1.
If I have too many apps opened and stored in RAM (like 5+ or so; such as fb, messenger, email, youtube, instagram, ...), it often causes restart of the apps while switching between these apps I have already opened and stored in RAM. Even if it shows I have 1,5 GB RAM free. What's the point in high RAM capacity in phones (3-6 GB thesedays) when even with that much RAM (and that much FREE RAM) the phone isn't able to hold them really "opened" in RAM all and the apps "reloads" (as if it was launched for the first time) when you try to recall/launch them (quickly, but still).
It doesn't bother me that much generally, but only with one app - GPS tracking apps. After some time (maybe 1-2 hours) it always "drops" the app from RAM (it's still in recent apps though) therefore deleting my existing workout and tracked route. It's annoying. And yes I have the tracking apps selected in "protected apps". It happens still. Once I rebooted the phone, cleared apps stored in RAM so the only app running was Runkeeper. I went cycling and after some time (1-2 hours) I stopped, took the phone out of pocket, turned the display on, clicked on the GPS tracking app and it started to reopen/reload itself and once it reopens -> no trace of my existing workout, everything was gone. All of that with ~2.2 GB of free RAM.
What good does 2.2 GB of "free RAM" do when the phone isn't able to keep the only running app in the background for few hours? I tried many GPS tracking apps, happens always. It didn't happen with my Moto G (1st gen.; 2013) with 1 GB of RAM, but it happens with a lot newer and better phone with 4 GB of RAM?
Any tips for that, anyone? Please?
Don't know if this will help or not. Had a similar issue with a music player app. Gave it permission access for 'Phone'. Did not happen again till now. You can try that out.
You can also try Setting>Apps>Settings>Special Access>Ignore Battery Optimization>'Your App'>Allow
Ever since the most recent updates, especially the Android 13 one (stock), I can't seem to multitask with this phone (A51). Browsing one or two websites with chrome it's too much for the poor thing, and decides to cut off background apps that I explicitely told him not to cut off.
So while browsing after a while Spotify crashes, Adguard crashes, the music player crashes, the youtube vanced playback crashes etc.
I don't have any launchers or actually use many apps, I have one messaging app and a social network installed but for everything else I try to use Chrome in order to save memory storage and give them a little less data.
It seems as if battery optimization is having a hard time with my phone (and I explicitely told it not to can Adguard, yet it still does), when it didn't use to. Any ideas? My phone's ram is constantly at 50% full, so there should be space for a few webpages. I disabled Samsung SmartRAM.
