Battery Life

Battery Life is always an issue for Smartphones and HTC Desire the battery performance is below average. HTC Could have put in a powerful battery when the Device is so much social networking enabled.

  • HTC Desire battery life improves over time such you may have experienced in many rechargeable gadget.
  • With Social Networking apps (Twitter, Friend Stream, Facebook) on about 12 hours
  • Social Networking activities such as frequent Twitter posts, Facebook updates and browsing for hours might drain the battery. With active on all these social apps the battery might last for 7 – 8 hours give or take.
  • Battery and performance tips are available on the Part 7 of this series which will allow you to have at least 35% of battery life increase.

Quick Facts

Here are the things you might not know about HTC Desire:

  • Automatically lowers the ringer volume as soon as the phone is picked up and also Mutes the ringer when the phone is flipped face down
  • Backs up certain data and settings to the microSD card automatically, such as SMS/MMS messages, bookmarks, Wi-Fi passwords, and more
  • Weights 5 grams more than Nexus One
  • Does not have noise cancelling microphone
  • Doesn’t come with the Docking Pin as Nexus One
  • HTC Desire ROM can be used in Nexus One
  • Desire has 64MB more RAM than Nexus One
  • Contains Adobe Flash Lite 10.1
  • Allows you to see what actually drains your battery
  • Most applications won’t run without a microSD card inserted
  • Screen vibration feedback works on the virtual QWERTY keyboard but nowhere else on the home screen

The HTC Desire UI is generally fast and we must give credit for that to the faster CPU and the optimized software. This time around the UI performance is great – even with lots of files on the microSD card.

The only noticeable slowdown is with widgets that need internet connection to refresh content, but that’s completely normal.

Benchmark Test:

Here is  small comparison how the HTC Desire and Sony Ericsson XPERIA X10 in terms of performance. Used the free apps from the Android Market for the test and the results are down below here for you to see.

GPU Comparison : Provided by one of my Reader

Update: The GPU comes with the Qualcomm SnapDragon Chip-set.

It’s quite awesome really, here is a GPU comparison for some of the latest smartphones:

HTC Desire: Qualcomm QSD8250 with Snapdragon = 22 million triangles/sec
Nexus One: Qualcomm QSD8×50 with Adreno 200 = 22 million triangles/sec
Motorola Droid: TI OMAP3430 with PowerVR SGX530 = 7 million triangles/sec

iPhone 3G S: 600 MHz Cortex-A8 with PowerVR SGX535 = 28 million triangles/sec
Samsung Galaxy S: S5PC110 with PowerVR SGX540 = 90 million triangles/sec

Nokia N900: 600 MHz Cortex-A8 with PowerVR SGX530 = 14 million triangles/sec
