Tips on How to Preserve iPhone Battery Life

There are few things that we could do to preserve battery life on iPhone.

  1. Mail Settings
    1. Turn off Push Email if you don’t use it
    2. Fetching email manually instead of getting it on specific interval will help with your battery life.
  2. Location Settings
    1. Turn off Location Service. Switch it On only when you need it, eg when using Maps (GPS).
    2. The application will ask you whether you allow for it to turn on Location Service and use your location.
  3. Brightness
    1. 30% of brightness usually sufficient for different type of light.
    2. Set Auto Brightness to “On”. This will allow iPhone light sensor to adjust brightness automatically.

How long the battery life can stay? It depends on your usage. GPS / Location service are power hunger processing, you may find your battery run out quickly if you use those features. Playing IPod especially videos will also drains your battery quickly.

Hope tips above will help to preserve battery life on your iPhone.

Battery Life of iPhone 3G after Installing OS 3.0

After installing OS 3.0 on iPhone 3G’s battery runs out around 20% faster than it used to be. I used to be able to use my mobile for 2-3 days before recharging it. Now I have to charge it every single day.

I have iPhone 3G Push Notification turned on all the time. It seems to be the cause of the battery runs out so quickly. Apple introduces this Push Notification to prevent applications running as background process. The thought was by stopping application running on background, they would be able to conserve battery life and preserve performance of the iPhone devices.

Well, that’s not seems to be the case, the battery runs out lots quicker with Push Notification turned on. Currently, I have two Push Notification Applications that I use often are HeyWay and Trapster.

So, if you wandering why Battery Life of iPhone 3G after Installing OS 3.0 seems to run out quicker, well, yes it is.

UPDATE: I turned of Location Service under General Settings, it seems to help a bit. Battery life can now last for 1.5 day at least.

Silverlight 2 TextBlock disappeared after being set to invisible

If you find your Silverlight TextBlock disappear after you set it to invisible. You may want to check its opacity property.

The case was to make TextBlock control visible and collapse based on certain condition. For some strange reason the TextBlock didn’t appear after I set the visibility back to visible. As I was using MVVM (Model View View Model) pattern, the TextBlock’s visibility was bound to view model object visibility property. I checked the control visibility property, it showed visible. Then I found the opacity was zero, I didn’t set the opacity to zero, but I guess when I dynamically attach the textbox to the parent with opacity 0, for some reason it follows previous opacity value of parent. Even tough, the parent already has opacity value of 1.0.

Yeap once again on cutting edge. So, if you find same situation Silverlight 2 TextBlock dissapearing, You may want to check its opacity.
