Samsung Jack phone and battery will not last more than 3 hours even with no phone usage.

if you are talking battery time
it depends on the use
if you just make calls the battery last long --day or 2
if you use a lot of data hours
download a user manual and it gives approximate battery usage

try to stop it with androd apps manager

You are likely running an old version of the firmware / ROM. See if Samsung has a new version, or if you are comfortable with rooting visit XDA Developers forums to learn how to get a newer version with more up to date power management and battery conditioning updates.

Battery and Usage under Settings will tell you exactly what is draining your battery. You should power your phone off for a few minutes every 2 or 3 days.

Also try letting the battery die completely, and charging up to full UNINTERUPTED. This will help the phone reset it's battery meter, which may be the problem.

Your next step would be to backup the phone, apps, and SD Card files, and perform a factory restore. Then reinstall your apps and replace your data.

If that fails, you may simply need to purchase a new battery.

Hi, What causes the battery usage to be short life span is becausethe battery cell of the battery is dead and too weak to power on the phone for too long.

You will need to replace the battery with another one.
Before you use the battery, you will need to charge for longer hours(4to 6 hours) before you use.

Have a nice day.

Hello there, the Nintendo DS Lite has four levels of brightness. The battery will last 15-19 hours on the lowest settings, and 5-8 hours on the brightest.This can also vary depending on the type of game activity."
So the DS should last the whole time in even on the highest brightness settings, if fully charged. Nintendo states that it takes 3 hours to fully charge the DS. 

hope this helped, also this site will also help you to get your ds battery to last for longer
