Hi
I wiped my phone, was on doc's js8 custom rom with Speedmod Froyo kernal. Before that I was on Stock JPU with CF-Root.
Flashed XXJVP stock rom from Ramad's thread via ODIN, rebooted, installed Speedmod for GB, rebooted, flash Ramad's Deodexed XXJVP stock rom and then re flashed Speedmod for GB...
Battery for normal use is great, but watching a video is eating way too much battery...
When I was on JPU, I was able to watch two full movies (about 3 hours total) played a wordcross game and then watched several music videos and listened to a load of .mp3 whilst on a flight to Eygpt, using the stock Samsung player, screen brightness set to 2% and the player brightness set to 2%, phone in Airplane mode...
After 5-6 hours use I had gone from 95% battery to around 45-50%.
Now on JVP, I ran a video for 1 hour and with the stock player again set to the same brightess, 2%... after the hour checked my battery and it was down nearly 50%
This was Not in Airplane mode this time, but would this make a big difference, in Normal use I loose 1.09% battery per hour!
Has anybody else on JVP noticed similar, or is it just my phone?
This is almost in every ROM the problem;-)
This is Not the normal Android OS or System drain, my battery lasts two days easily, as long as I don't use the video player and the drain stops when the video player stops.
hmmm data connection does consume lot of battery but 1-2%/hr at the most... so i'm guessing u have lot of unnecessary apps running, when u dont actually use it. go to settings and in about phone check the battery usage, check the apps which use the battery at the most and delete them if possible. else u can use a task manager and kill unwanted processes from time to time. hope this helps!
Cheers but tried that already, biggest app drain during the 1 hour video playback was media services 4%. Nothing else stood out, and as I said in op, normaly battery drain under same conditions but no video playback, I only loose 1.09% per hour, so it looks like the video player did all the damage?

in that case use mobo player for viewing videos(much better than stock plus it supports more formats).. use this n see if u still have drain
depends of what video codec using your file... some codecs have low battery drain some codecs medium and some high... compare working on JPU and JVP with the same video...
The video s are all .avi or mp4, same as I played when on jpu rom.

First off, sorry if this is similar to another thread. I had very specific things happening so I thought it warranted a new post.
Okay, so I was wondering if my battery life was normal. I was browsing the web earlier for about one hour (looking for info on my battery troubled, oddly enough) on wifi. After I finished I noticed my battery had dropped significantly: from 79 to 58 to be precise. I use the lowest backlight setting, I kill apps frequently.
My ROM right now is Serendipity 6.1, stock serendipity kernel. No oc or uv. Is this normal for a battery to die so quickly?

ive been having the same problem(sudden change of battery levels). Wifi has been known to kill batteries on the captivate, or at least in my opinion. also, check if you have any background apps running that use up cpu resources. those kill your battery too.

depending on what you are doing.. if you watch movies thru it which requires intensive processor use then thats normal it really depends...it also eats up battery easily if backlight is set at the highest.

It's possible that you have a bad flash. You could try flashing back to stock, running master clear, and then reflashing Serendipity.

Actually, watching movies does not use a lot of processing power. On a recent flight I watched over 6 hours of movies and still had over 30% battery left when I landed. You can also adjust the backlight from within the movie player so it isn't too bright. Wifi is a huge drain, especially with the screen on while web surfing. Another drain is poor cell service since the phone will be continuously looking for signal. Having only 1-2 bars reception uses more power than having 4-5. When it drops below one bar repeatedly it uses even more. A 20% drop after an hour of web surfing on wifi is not that unusual.

yeah you have a point in there that's why I say it depends. when you only watch a you tube that has short buffering time it may not uses more processing power try watching movies from other site like webtv360 that constantly buffer until the end of the movie it will drain your battery fast sky high. maybe clearing dalvik cache and battery stats or even doing factory reset with his current rom will solve the issue as there might be some datas left lurking from previous rom after flashing that causes undesired effect with regards to battery drain. most of the time this will cure some icompatibility issues and force closes, doing this after flashing a new rom will save you more headache in the future.
Thanks for the help guys. I'll try to keep it off of wifi when im not using it and I've been putting it in airplane mode at points during he day. I just undervolted, so hopefully that'll help my battery.

Ahh, you didn't say streaming movies from a website. That's a double whammy since you are using the network or wifi and having to decode the stream on the fly. Very processor intensive, as you stated. I was referring to watching movies stored on my external SD card.
Mediaserver is draining a lot of my battery as in 54% im on Galaxy Droid 3.3 JVA and ive search other related threads but they dont seem to have a fix anyone have answers?
I noticed that to, Media Server was taking 35% of my battery so I searched and found this post here http://forum.xda-developers.com/showthread.php?t=980575 .
According to that post a corrupt file (like a picture or mp3) can cause the battery drain. So I went through my files and found that I had 3 corrupt pictures. I deleted them and boom, battery usage from Media Server went down to 7%.
Three days later the battery usage was back up to 30%. This time I haven't found a solution .
Btw I'm using a Nexus S.
My phone's Cell Standby is eating like 80% of my battery even in flight mode. even if I don't use the phone at all after full charging, the battery goes from 90% to 20% in just about 10-12 hours. I don't know what's causing the problem.
In the cell standby battery status it shows Time without network: 100%
Is there any solution to this? This problem started after I flashed to Gingerbread 2.3.4 XXJVP (GT-I9000)
same problem here on ICS 4.2. Media server is keeping my phone awake and so unable to get into deep idle. Really draining the batter hanging the CPU around 400mhz. So far after resetting my galaxy, it's been able to delve into deep idle. But still not sure what caused the media server problem in the first place, and i doubt it's the last time ill see it. In which case i may have to try going through my sd files as in the post above.
i have that problem too..
but only when i listen music with poweramp.
i have even deleted my photos and stuff
is it possible somehow that songs id3 tags causes these problems?
Hmm yeh not sure. I also had a problem with my stock music player not being able to play any songs at all. So I wonder if that did it for me.

Well idont know.maybe there is corrupted file in my music files.but this is first time i have these problems. Been using many roms before and never had problems with mediaserver..
Installed Skype and called once. Battery drainage after installation, turned out the Skype contact sync was causing the issue. Unticked the sync box and battery life back to normal.
How to fix it
The mediaserver thing runs when you open media(photos, music videos) in any program. If you inactivate it you will not be able to access your media. So when your finished with viewing photos or music just go to
apps-->all-->mediastorage-->force stop
DONT CLEAR DATA, I DID IT ONCE AND I COULDN'T ACCESS MY MUSIC FOR A DAY!!!
Hi,
Sorry for the stupid query but i just want to know if is normal or not.
Optimus 2x P990 2.3.4 stock fairly new phone so the battery hasn't got the chance to do many charge cycles (only 4)
The thing is when watching a movie (normal m4v or avi not HD or such) i see the battery drain 1% every 3 minutes so if i start a movie with 100% i get with around 65-68% ~ of battery left.
low brightness, no wifi, no data, no BT, low sound and using MX Videoplayer.
Is the drainage fair or is too much ??......1% every 2-3 minutes of movie played.
Thanx,
I think thats good draining percent for watching video =)
I agree with that. The draining is normal.
But maybe the stock video player is a bit more efficient and battery friendly because of the better hw acceleration.
Hello!
Yes, this is perfectly normal as you should keep in mind what playing video means for your device…
CPU can’t sleep, the backlight of your display (on of the heaviest power consumer in this phone) is alight all the time, data access to SD card all the time and you have sound playing too - I assume.
I usually get 2h-4h of video playback on a full charge before 15% warning pops up – depending on other apps running in the background like i.e. gsm-data/cloud syncs etc.
In Airplane mode using the phone on a flight I get max. 5h.
So if you plan to use the phone as a video player, I would recommend to have a external power source handy…
BTW: I usually use moboplayer and non converted standard resolution mpeg-files from onlinetvrecorder.com.
thanx all for replay,
and yes with stock player i get better battery life.
Hi,
I'm using my Galaxy S as a music player (usually on flightmode, low brightness, black background etc).
I'm on 2.3.6 XWJW5 Voodoo kernel right now, but I'm not too happy with the battery life.
I'm wondering which firmware/rom/kernel combination yields the best results.
*I dont mind downgrading to Froyo stock or something as long as it has very good battery life, especially when my screen is off while playing music.
Thanks in advance.
**Also, does my phone go to deep sleep when playing music with PowerAmp (to save more battery)? Is SetCPU recommended to underclock when screen is off?

My experience says CM7 with the kernel that comes with it... it gave me a battery life of around 30-35 hours with moderate usage..
bump
I would try one of Darky's older Roms (I think something around 10.2 or 9.5 should be the best for you, they had their own kernel called darkcore).
I remember having battery times about 2-3 days with moderate usage (should be even better in flight mode!)

I'd recommend SauROM and Darky for GB, both are JW6 and do a great job. You also can't go wrong with Stock JW4 with HC SpeedMod + Lagfix tbh!
Hi everyone,
i wanted to ask if there's an app or a way to make my S3 Mini enter deep sleep mode even when I'm listening to music in the background (music app not open), 'cause now it stays 50% awake and 50% sleeping and drains my battery extremelly fast - about 30 mins of music listening drained about 15% of my battery without me doing anything else and having the screen off all the time through that period.I read a similar thread on some forum, but there wasn't a way to do this described there {don't remember which forum that was on}.
I'll even settle for another music app (not the default one, if it can't be done with it) which has playlist widget support and decent controls [and of course one which makes the phone go to deep sleep mode while it's on in the background]
I'm running on a pre-rooted android 4.1.1
THANKS IN ADVANCE TO ANYONE WHO HELPS ME OUT AS THIS HAS BEEN AN ISSUE FOR QUITE SOME TIME NOW
Mind if I ask why you use 4.1.1 and not 4.1.2 or CM10/11? I've never had this issue on any stock rom with the default player so a firmware upgrade should take care of it.

if CPU enters deep sleep, how would the phone be able to play music?

I was on 4.1.2 for more than half a year, but 2 days ago switched back to 4.1.1 'cause the ripple effect on the lock screen is gone in android 4.1.2 and later And I kinda have some apps installed so I dont really wanna flash a new rom

Well yeah, but then again why does the FM Radio app drain battery extremely slow when using it almost the same amount of time as the music player (perhaps even longer) ? I don't know maybe I haven't adapted to android as this is my first android phone ever and i have had it for almost a year now (never had battery problems with my other phones - all were Nokia )

try dmod v6 its awesome
battery break
I think the problem isn't with your music player, the problem it's wth your battery, because i use stock music player and 3g for 1 hour, and my battery only drain 10%
Well, just to say that I use playerpro with maclaw's cm 10.2, for a long time & never had battery draining

Maybe. Because when i listen to music my screen is off all the time and i have 3g manager installed, which means that my 3g is also disabled when screen is locked. Let's hope it's the battery - seems like the easiest way to fix the problem
