How to Save Power on Android phone

asker

Lurker
Hey, guys. I'm a new user of android phone. My phone uses out battery power very quickly, and i heard many people complain about the short duration of Android phones. Someone told me that's because many apps still work on the background after you close them. He told me to use Advanced Task Killer to shut down apps. But others said Task Killer was harmful to the OS. What should i do to save power. Please Help me.
 
Download either Juice Defender or Green Power. These are automatic battery saving apps from the market. They do everything from closing apps automatically, turning off data connection automatically in low battery situations and in times of low data traffic (with periodic) polling, turning wifi on and off automatically, downclocking for power saving, turning down brightness etc.

Basically they are install, setup and forget apps to save your battery
 
No-go for task killers. Not only can they hurt your phone, but they also use more battery than they save.

The other battery saver apps are okay I guess, haven't really tried them. Usually, you don't need one of those apps, but rather you can just configure the battery settings in SETTINGS--POWER.

There you will be able to do what the person above me said without an app.

Some phones dont have Settings>Power. Mine doesnt. You mean there is a setting in the phone to downlclock the CPU when the screen is idle automatically? Or to turn off packet data when the screen turns off while there is no data traffic and check again every 15min or so to see if some traffic wants to go through? Sort of doubt it can be done without an app.

Either way, task killers are a no go. They do more harm than good. You can take that to the bank.

I just keep my data off until I want to use the phone. Then I just pull down my notif. bar and press Mobile Internet On. Not that hard.

My phone has settings that allow it to only use data when asked to by me, to go into airplane mode except wifi when charging, etc...
 
Then why does the Samsung Galaxy S 4G have one provided by either Samsung or T Mobile?

The better question to ask, since when has Samsung been known to be the crack Android programmers? Last time I checked TouchWiz was the scourge of Android overlays...;)
 
Don't see the need for task killers either.

Them apps that run in the background aren’t doing any harm, when you close them with a task killer it's just going to reopen.

Then what happens? you close it, it opens, you close it, it opens. That's all eating into your battery.

One of Androids assets is true multitasking,why not let it do it's job?


The screen I find is the biggest culprit when it comes to battery, turn the screen brightness down when possible and it will definitely help.
 
Almost everyone who complains to me about their battery life has the brightness at 100%, constant data, and wifi on. They need people killers, not task killers.
 
A good first place to start off someone new to Android is to show them the Power Control widget

Long press on a 4 space wide, 1 space tall (4x1) area of one of your home screens

Then select widgets > (android widgets)* > Power Control


*(some phones will have you select "android widgets", others will not)


This will let you easily turn on an off some of the big battery killing features of the phone.

There are more advanced things to do also, but this is a great place to start off anyone new to Android.

It should look like this:
