There are certain things to keep in mind that will improve the battery life of the HTC Eris. For one, always change the sleep option settings to “Never Sleep”. It also helps to set the brightness setting to “automatic” so that the light sensor of the device will determine what is the appropriate brightness setting according to ambient light conditions.
Likewise, always turn off the GPS setting to shut down anything that the user does not require for a particular instance. Turn off, too, other tools and widgets that are not needed such as WiFi and Bluetooth. To do this, go to the Settings folder and look for wireless connection settings. Turn off the Mobile Network when not in use; although this would cut off the connection of the mobile device to the Internet it will consequently result in tremendous savings in battery life.
Other HTC Droid Eris apps that should be turned off include the audible touchtones which can be accessed by going to Settings folder and Sounds and Display option. The haptic feedback option must also be turned off, as well as the screen animations. Downloading applications that can help in turning off unnecessary apps can also help. Users can find these apps like the Advanced Task Killer that will kill off apps and prevent it from running and draining the battery life of the HTC Eris.
The Droid Lithium-ion batteries that are used by the HTC Eris should also be used regularly for optimum performance. It must be recharged completely for at least once in a month. The battery of the HTC Eris stops charging itself when it is already full. It won’t charge itself even if it is left connected overnight.
