Many HD2 users who have installed Windows Phone 7 on their device have been complaining about the battery indicator not showing them the correct battery level. This can be quite an annoyance, as you can’t predict when your phone will run out of battery while you are out and about. Fortunately, we now have a fix for this problem. Read on for details.

Not willing to take the risk of inaccurate battery level prediction anymore, XDA-Developer forum member arkatis has discovered a fix for this issue, resulting in proper battery level indication. If you own a HD2 with Windows phone 7, this is a must apply hack. The fix involves applying a simple registry tweak to improve the battery indicator for the device.

  1. Before you begin, charge your phone till the battery charging indicator turns green.
  2. Download and the Windows Phone 7 Registry Editor from the link given below, and extract the XAP file from the zip file that you downloaded.
  3. Install the Registry Editor to your phone using the XAP file. You can do it easily using our previously featured Tom XAP Installer.
  4. Now disconnect the device from your computer and make sure not to plug it into any power source for the next steps.
  5. Open Registry Editor on your phone and go to the registry path:
    Local machine/system/state/batteryux/MainIntervalIndex
  6. Change the value shown there from 6 (or whatever is present there) to 20 and press OK.
  7. Doing so will change the battery level shown at top automatically to full. Don’t worry about it.
  8. Now go back to the same registry path, change the value from 20 to 80 this time, and press OK.
  9. Restart your phone and connect to the A/C charger till it charges to maximum.

That’s it. The battery fix has been applied, and now your device should show the correct battery level. No more leaving the house thinking your phone has enough juice for a few hours, only to find it running out of battery in a few minutes and then having to give explanations to friends, family or coworkers why your phone was off.
