How to get the best sound quality out of this great phone?

[mashac]

I bought a Samsung captivate from a friend yesterday. He was running Kitkat on it and it is very slow. My only use of it as a phone is recieving calls and text messages, nothing else like facebook,whatsapp or anything. My main use for this phone is to use it as a portable music player as I travels alot. I saw an old thread from head-fi that, this phone can be transformed into an Audiophile level music player using a Voodoo kernel and an Voodoo control plus App. But that was in 2011. What is the current situation? How can I get the best sound and best battery life out of this great device? I mean, which rom or kernal or modes to get the best sound quality out of this phone?

I use DSP Manager http://android.appstorm.net/how-to/music/install-and-configure-dsp-manager-on-any-rom/ It seems to make better sound than the stock sound driver. Battery Life on the other hand I'm not too sure about, and I have used 3 different batteries with the same outcome. You could wipe battery data

Erasing the battery stats (for you rooters/flashers)
Sometimes you just want your phone to forget everything he thinks he knows about his battery, and re-learn it from scratch. Your phone maintains a file with statistics on battery usage, which in turn is used to help calculate battery life at any given time. Sometimes, especially if you've been playing with ROMs, kernels, and lagfixes, the stats in the file just aren't applicable anymore to how the hardware is being used, so you get crazy battery drain.

Clockwork Recovery has a simple function to wipe the battery stats. If you can't run Clockwork, use ADB or a terminal emulator (search the market) to delete that battery stats file located at /data/system/batterystats.bin. The link at the bottom to joeybear's thread has a little more info.

The general idea is to start by trying the above - make sure it isn't your own fault or maybe just a bad battery, then drain, bump charge, and wipe stats - in that order.

There are lots of ideas about what may or may not happen when you experiment with the above. Wiping battery stats after a ROM flash that already wiped them for you is at least redundant and may even contribute to a battery drain problem. Some say you should wipe first and then drain and bump charge. Be careful about wiping stats and bump charging too much, though. Over-charging your battery will hasten its demise.

HOWEVER, if you're like I was when I first started this thread, you've seen the above recommended many times, and none of it has ever helped you one bit with an actual sudden battery drain problem. http://forum.xda-developers.com/showthread.php?t=765656

I use my old captivate strictly as an mp3 player using the captivating X8.1 rom and devil kernel. The voodoo sound app is still kicking around the Web I'm sure.

Instead of using the headphone jack, I made a line out cable that plugs into the charge port and on the other end of the cable is a line out 3.5mm jack and a regular USB plug to charge at the same time. All the info for wiring and resistors to use I got searching around this forum and the "fun with resistors" thread in the i9000 forums.

Using Power amp for my player app, with all other non essential apps removed, and in airplane mode with WiFi enabled I get about 15 hours of music from my own collection on a 32gb micro sd card. It can also play wile charging with minimal or no noise depending on the charger used.

It really makes a great mp3 player.
