POOR BATTERY LIFE

Hi jaomat,

Batteries ship to the stores with only a third of a charge.  That's why it is so important that you run it until its completely dead the first time and then charge it.  If you have to charge it every three hours I would bet you didn't run it down completely the first time.  Here are a few settings to change to increase battery life.

1. Set the screen brightness really low.
2. Turn off wifi when you aren't using it.
3. Make sure all unused apps are properly closed and aren't running unnecessarily. 

If CC made a suggestion about your problem, then at least try it out.  Just because you "don't feel like it" doesn't mean the problem will fix itself.  Be proactive!  Hope this helps!

All good things to know. Thanks for the input!

One thing i've noticed is that when I first got it, the battery was lasting about an hour before it died. This also had alot to do with it was a new phone for me and was constantly checking out apps and downloading more. But since I stopped playing with it all the time, the battery will last me an entire work day plus some hours into the evening before havng to charge it.

I can't say enough about the app "Juice Defender"

Even with heavy use, I can get from morning to bed time on one charge.

The way it works is it turns off the phone features (wifi, GPS, syncing) only turning it on for say, 2 min every hour so that it can sync. It also disables them when your screen is off, turning them back on when you turn your screen on.

On my old G1 I had to use the task killer to make sure that programs weren't hogging up all my batter life, but on the mt3gs I have not had to do this. The main three things that kill the battery on the slide are; the screen, the WiFi, and the biggest hog: the GPS!
What I did was put widgets on my desktop that allowed me to turn on and off the WiFi, the Bluetooth, and the GPS as well as see their status (on or off).
To do this follow these steps:
1. On the home screen press the menu button with the three horizontal lines.
2. Press "add to home" plus sign icon. (You may get a message saying "You home screen is full", make sure that you have room for three icons, one for Wifi, Bluetooth, and GPS)
3. Click Widget.
4. Scroll down to "settings" and click it.
5. You will see widgets for; Airplane Mode, Bluetooth, GPS, Mobile Network, Wi-Fi. Select the GPS and it will be added to your desktop.
6. Repeat steps 1-5 adding a widget for Bluetooth and Wi-Fi as well.

This makes it really easy to see if your GPS and WiFi are on and allows you to turn them off when not in use.

I recommend that you only have the WiFi on when you want to surf the net and you are in range of a WiFi access point that you can connect to. Having WiFi on all the time WILL drain the battery because it is always searching for access points.
Same thing with the GPS. Keep it off unless you are planning to use the Navigation or My Location in maps.

After installing these widgets I have had no problem with battery life. I just charge my mt3gs every night when I am sleeping.

Hope this was useful! 

I looked on the mugen power site and did NOT see one for the Mytouch slide 3g. Only for the regular mytouch.

which uses more power? WiFi or 3G?

Generally speaking I was told that wifi uses less power in general than 3G, but perhaps I was misled?  when I'm at home (where I have a wifi network) I turn off 3G and turn on wifi. should I turn wifi off and run 3g instead (when I'm not on the web)?

is there a fast way (or app) to switch between 3G (WCDMA) and GSM (Edge)?  right now i have to goto Settings>Wireless & Networks>Mobile Networks>Network Mode. too many steps

i've seen 1500mah batteries for the 3g slide on ebay, but I'm reluctant to try without reading reviews.
