charge them before they are depleted?
Its a bit of a boring question, but Im curious
With one of my older non WM phones, i had it plugged into the mains quite often, and then slowly the battery performance degraded until I could only get just under a days worth of mild usage before the poor thing would give in.
Im now rather paranoid to charge my Elfin before the battery dies so I dont reduce the battery life. Im currently getting two days out of it with quite frequent usage.
When its low on juice at the end of a day, but not completely empty, I end up turing on the bluetooth and wifi, play music on both windows media player and the audio manager, play a video on coreplayer and play the falling sand game, just to get the CPU usage up. This then eats up the battery so it will become empty so I feel I can feel I can put it on to charge before I go off to sleep.
Im just really wanting to find out if charging before its empty really does have an effect, or if its just my brain playing tricks, and has anyone else had experiences like my old phone?
Thanks, Cris
I have had my elfin for almost a year and a half now and put it on the charger in my car every time I get in and charge at home almost every night and have never had a problem. If I forget to put it on the charger at night, I still don't have any problems, battery easily last over a day. I have recently gone away on a trip and forgot my charger and with average useage was able to get over three days use before I started getting worried about low battery.

falling sand ppc game?! please post a link!
You are thinking of the old NiCad ( nickel cadmium ) batteries, which had a definite memory to them. If you did not cycle them through a full charge everytime, they would develop a capacity " memory ", The new Lithium Ion batteries have no such " memory " and can be partially deplited and charged again with no ill effects.

There is one point to notice tho.
you should NEVER completely run your battery out of power or it'll die.
Lithium batteries should be taken to 95-99% charge and then used to about 5%...
Conditioned the battery gauge, bought a new charger from Amazon, and I've been very happy with the performance over the past 5 or 6 weeks. With my regular phone usage pattern, the battery lasts a couple of days.
That all changed this past weekend and I couldn't figure out why. I had taken a 500 mile roundtrip (GPS worked perfectly, fyi) with the phone plugged in to a car charger and all I could guess was that it somehow messed up my battery. I had installed one other application, but the battery stats didn't show any unusual behavior or partial wake usage, and the problem persisted after I uninstalled that app.
Then it hit me that I had changed one other thing: I had purchased a 32GB SanDisk microSD card from Verizon and the travel weekend was the first time that I had left it in the phone continuously.
I have experimented over the past few days and it is clear: my battery lasts for a significant time without the microSD card, while it drains ridiculously quickly (with no phone usage) if the microSD card is in. The comparison is like night and day. Two days of regular phone usage without an external microSD card installed, compared to less than a day of minimal phone usage with an external microSD card installed.
Has anyone else experienced this? Anyone else using the 32GB SanDisk from Verizon? Either way, which brand/capacity cards are other people using? I am not even certain which company I should report this to!
(Captivate on AT&T with the stock firmware)
I have an 8GB SanDisk card. I have not tried without the card, but I get one to two days of regular usage with it in.
Using an 8GB Trancend class 6 card and get great battery life.
In the past Samsung has had issues with SD cards killing battery life if you set things like the camera to store your pics on it. I had a eternity and if I set the phone to store pics on my SD card the battery would be dead in 4-5 hours, store pics on the phone and the battery lasts a week.
So I guess this would not be unheard of with Samsung phones.
Thank you, Pmac25, that perfectly describes my situation.
I had it set to store/record photos and video to the external microSD card on Saturday and I didn't change it back to the internal card when I was finished.
If I leave the Camera set to store things on the internal card and just use the external for previously stored music/movies, will it have the same effect on the battery?
Cheers for pointing out the issue, much obliged.
I have a 32GB SDcard installed. I only store older data on that card and I get 2 days on one charge.
Pmac25, does your observation also apply to storing/listening to music on the SD card?

I have noticed that running video/music from the external SD kills like 1% of battery life every 5 minues on my phone!. After making this observation, i moved some commonly used stuff to the internal sd and have not noticed such a drastic reduction in juice.

well this sucks..!! I have all my music and videos stored on external SD card so that they are portable I can just take sd card and all my music n vids are there...but now it seems I will have to transfer all my stuff on internal storage. But then whats the use of having external card when it drains a lot more battery. company like samsung should have fixed this issue long time ago.

1% every 5 minutes would equate to 500 minutes of continuous use (8.3 hours). I guess it depends how much of your mix is video and how much was audio.
The hardest part of any battery test is determining if anything else has been left running in the background between tests.
I have all my music and movies on the external card, but I record pics and video to my internal card.
I am not to sure about storing/listening to music off the SD Card. Like I said the Eternity has this issue and I have not really checked to see if the Captivate had it or not.
I have music and a couple movies on my Ext. SD Card and right now I have the camera set to store there as well. I guess I should run a test and see if the SD Card issue is still there.
If I remember right on the Eternity the bigger the SD Card the faster if drained the battery.
Ok now you guys got me thinking. Is the battery issues with the Cappy the same as with the Eternity.
I will see if I can find the thread on the Eternity board about the issue.
Did some more testing.
Empty external 32GB microSD card installed. Camera app set to store on the internal card, so nothing was "touching" the external card.
Battery drain was still substantially higher than I normally experience; test was run with almost no regular phone use today (a few texts and a few mins of phone calls). It isn't quite as bad as when I had the camera app set to store on the external card, but still a far cry from my battery performance with no external card installed and much higher actual phone usage (with the phone in the same location, with the same wireless connection, every other variable I can think of the same).
I did a quick test. Pulled out my 4GB SD card and waited 2 days to see what would happen. With normal use, my phone lasted about 12 hours longer (about 1.5 days) without the card. Put the card back in and my phone barely last 20 hours. I'm leaving the card out for now.
Incredible how the card has that much of a drain on the battery.

Very interesting
Very intersting, wish more people would jump in on this. Doing test myself, but this may explain my battery issues. Seems thats about the time it started draining faster is when installed my 16GB micro.
Are there any cases for the Captivate that have a microSD card holder? That would be really convenient; I have a 32gb card as well.
A firmware bug could potentially cause this extra battery drain when microSD is not in use. Did you guys that notice the battery issue with SD card all still running stock JF6 firmware?

May be you are right. I am running stock firmware. I hope samsung will fix this issue with froyo update. I guess we can suggest these changes on twitter or something. that is what I read some where that you can reach samsung & suggest then some thing on twitter they were very active ob twitter promoting this galaxy series.

I left my phone off the charger last night for 7 hours. With 16GB microSD card in and cameras are always set to save to external microSD card as well all my podcasts and movies are on the SD card as well. GMail sync, weather sync (every 3 hours) are both on. My phone battery dropped only 5%. And I'm running latest JH7 firmware. So, it is safe to say there is no battery drain on external SD card in JH7 firmware.
I'd love to try running this with no SD, but my lag fix is there... Ugh, I wonder if it worked be worth the experiment.

If your lag fix partition is on your external SD card, you will no doubt add extra battery drain to your phone because your external SD card will be accessed a lot while your phone is on.
So I have noticed while listening to music during the day its burning a lot of battery which I'd kinda understandable all my music is stored on a external class 4 sd card would it help battery life to move music to the internal hard drive or will it stay the same?
Thanks in advance for any help on this

Hello
I have a really strange issue I think everyone would be interested to hear about.
I have installed a new ROM and my batery is really bad. Losing 10% in 1 hour without doing nothing in stand-by. (WiFi, BT, Data etc are off).
Checking battery status sites Android OS as the major consumer of the juice. (80~90%)
However, when playing music (using PlayrPro) with 3,5 headphones or external speakers, the battery lasts really long time. I am losing at most 1% or even less.
----------
Now it is not any software and it is not the ROM. I have tried not installing any apps and I ahve tried to reinstall the ROM and other ROMs several times. I had this problem before, but i did not know PlayerPro could fix it. and actually after 1-3 monthes battery started to be just fine and I used to attribute this fact to some settings or apps I uninstalled recently. But i was wrong all the time. I still do not know what causes the battery drain so bad. and PlayerPro thing only adds to confusion.
Anyone has any ideas of what the problem can be and how to fix it?
Deep sleep?
It seems like phone is not going into deepsleep. However, whgen playing music - it goes to deepsleep. How come? How Player Pro can help sensation to deep sleep?
Used to use GPM for all my music needs, and it used to use so much battery (phone down to 60% or so after a total of 4 or 5 hours of music), even when the music was cached locally and my phone was on airplane mode. Battery usage from combined GPM and Mediaserver was about 40% or so. No extraneous sources of battery drain either (ie. no Google+ running in the back or anything like that).
Recently, I tried Apollo and copied some of my most frequently listened to music to the internal storage. I got away with listening a total of 6 or so hours of music, and it lost maybe 10-15% of my battery (also on airplane mode). Battery usage from Apollo (didn't even see Mediaserver) was also around 40%, but the drain was MUCH less.
Why is it that GPM music sucks up so much battery? I thought this phone had a dedicated part of the CPU that kept battery usage from music very very low.

I noticed that as well. The mediaserver I've actually noticed with every music app I've used. Pandora/SoundCloud.
Do you use the equalizer by any chance? Or any sound mods?
I used to experience the same thing with local playback, media server would be higher than I expected and GPM showed fairly high CPU times. Over all it was using the same or more battery than streaming lower quality files with Slacker.
That is no longer the case. Only thing I've changed is headphones and disabled the GPM equalizer.

No sound mods (by that you mean Viper or the like, right?), and I haven't messed with the EQ settings at all in GPM, not even sure if it's enabled by default or not. So does the dedicated part of the CPU that handles music playback not do EQ settings?
Remember when Google was teasing the audio tunneling to DSP feature for Kit Kat and our Nexus 5? Remember the 60 hours of promised music playback?
Yea. Good times.

Actually, I think I got pretty close to that with Apollo (6 hours of music for 10-15% battery, with some other apps sometimes waking the phone up and me using it a little). They weren't lying, but GPM doesn't use it (for me at the very least)

Perhaps it is GPM, because that is pretty much the only music app I use. Ironic that their music app wouldn't use a key feature of kit Kat.

I thought I'd chime in as well on this problem. I love my Nexus 5, a LOT! But this app really does drain battery for me. I thought maybe it was just a bug with my phone? But I see others are having this problem.
It is kinda ridiculous that listening to music takes up about as much battery as having the screen on! And it's off when I listen to music. I want to get rid of my messed up iPod Touch in favor or my N5 but the batter is really hit... I don't have the best signal either in some classes and my transit to school is horrible signal, so it also takes a hit on the battery life.
Does anyone know what the problem is? Also the system UI seems to drain battery too. D; why does Google Play Music do this??

You know what is weird? I tested GPM against Poweramp with the phone in airplane mode and it was SIGNIFICANTLY less power hungry. GPM used 1.5% an hour with headphones plugged in vs 4.5% for Poweramp with headphones plugged in. Going to have to run the same test on WiFi to see the difference playing music makes when GPM has internet access. From using it daily I can say its SIGNIFICANTLY more than 1.5% an hour.

Is this happening on wifi? Cellular? Or both? Certainly you will achieve much better battery life while streaming over wifi.

Huh... That is rather weird. I have tried at home on WiFi and it still drains like how it does on mobile data. Of course o don't stream on GPM, I have all pre-loaded songs from my iTunes folder on my Nexus 5 and listen that way, offline. I don't know why it drained so much for me and others but so little for you? Even airplane mode still drains, not as much, but barely noticeably slower.

With EQ off and not playing Flac files, GPM and media server seem to barely register after 2-3 hours of listening.

well for me its eating a lot of battery and I notice a lag when I play/pause and next a song??? I am using the latest PA with Franco kernel. I now use Walkman from Sony; it works way better. Less battery and doesn't lag.

I've been using Google play music for the longest time and haven't noticed any battery drain no more than any other app I'm using for hours at a time. If I am constantly playing music its expected to me that is that my battery will drain. I can get usually around 7-8 hours of non stop music while streaming and also switching from Google play music to tune in. Tune in on the other hand is a huge battery drain because for some reason it likes to stay running in the background and sometimes I forget to shut it off manually and eats my battery up quick lol

If you have music stored in the library download it for offline and see if that helps you. When I use to do that I could listen to music all day in airplane mode that is

Hmm, does anyone have any luck with keeping WiFi on and GPM running, but with the same songs looped? It shouldn't have to keep streaming due to the files being kept locally, yet it still has terrible drain for me
