[G2 and Desire Z General] funkadesi:
Its time we need a thread like this to ensure every G2 user is getting the best out of their battery.

Here are my tips:

- WiFi: Should ONLY be

ON

when you are actually using it!

- WiFi Sleep Policy=NEVER: it takes more time and power to seach for a Wi-Fi AP than actually staying connected to it.

Settings > Wireless & networks > Wi-Fi Settings > MENU > Advanced > Wi-Fi sleep policy > Never

.

- Bluetooth: Should ONLY be ON when you are actually using it!

- Use 2G when possible: If you know you are in a area with NO 3G support, than set your phone in 2G mode so it doesn't use power looking for 3G.

Settings > Wireless & networks > Mobile Networks > 2G only

- Haptic feedback=OFF: I personally leave this OFF because minor vibrations are annoying plus consume battery.

Settings > Sound > Haptic feedback

- Audible Selection=OFF: For obvious reasons, we use the touchscreen the entire time, enabling this will case battery drain everything you make a selection in Android, App, Web.

Settings > Sound > Audible Selection

- Display - BRIGHTNESS=30%: I use about 30% brightness when indoors - when I am outside I turn it up brighter using Power Control widget.

Settings > Display > Brightness

.

Note: You can also leave it on AUTO, which is will provide optimal bnrightness with respect to ambient light.

- Display - Animations=Your choice: I personally have ALL of them enabled, but that is scarificing a small amount of battery power. If you do NOT need the pretty transitions, you can opt for other options.

Settings > Display > Animation.

- Display - Screen Timeout=30: I leave mine at

30 seconds

, as I think that's ideal for most situations.

Settings > Display > Screen timeout.

- Location - Wireless networks=OFF : The phone uses tower and signal strength to calculate your

APPROXIMATE location

, which is a waste when you have GPS. NOTE: This feature assists in fiding your location indoors. If you plan on using GPS outside on than you should leave it OFF.

Settings > Location & Security

- Location - GPS=ON: It should be ON if you plan on using MAPS or Navigation. NOTE:

GPS is ONLY used when system needs it!

Having it Checked OFF does NOT help battery life. The only time GPS is active is when you see the icon in the notification bar.

Settings > Location & Security

MAJOR CONSIDERATIONS

- DATA - (3G/HSPA+) - Hogs the most battery, even more than the brightness of the phone. The reason for that is when you are surfing, searching, texting basically anythin that requires 3G/HSPA+ data the radio, CPU, and RAM are always working to ENCODE and DECODE data going in and out the device. This process requires all 3 major components to work simultaneously which draws more power from the the battery!

- Widgets - Widgets like facebook, twitter, weather, news do have processes running in the back which draw DATA depending on your refresh options. ie, You will draw less power if your facebook/twitter updates every 3 hours instead of 1.

- APPS - Always keep in mind that APPS like messengers and others which constantly need data DO run in the background. Background apps will draw DATA AS needed, which bring it back to the point above. Always make sure that you SIGN OUT of APPS that require background data, IF you don't plan on using them.

- Live Wallpaper - yes, it looks pretty as we all know it. Sadly, the truth is that both CPU and GPU are working hard in the background to bring a smile to your face when you look at the screen. Live wallpaper will affect your battery about 5 - 10%, dpepending on which one are you using.

- Vibration - Considered important as well.... if you are a CONSTANT texter/EMAIL-er AND you dont need Vibration, than you should turn it off. Vibration actually takes more battery power than actualy sounds.

- Volume - Should be considered important because the higher the volume the more battery power it'll take. If you can do just fine with a Mid-level volume than you should set ringer to mid level!

YOU SHOULD NOT USE A TASK KILLER APP
