How To Increase HTC EVO 4G’s Battery Life?

The first 4G smartphone HTC EVO 4G in US is available for sale from Sprint network. Although HTC EVO was reviewed as a phone of the future, it’s major complaint is its poor battery life.

Here is what the top reviews had to say about HTC EVO’s battery life.

  • htcevo How To Increase HTC EVO 4Gs Battery Life? “Battery on the EVO is shorter-lived than a plotline in a Seth McFarland show.”
  • CNET Review: “Battery drains quickly with 4G”
  • TechCrunch: “Horrible battery life, Terrible battery life, Really, really bad battery life”
  • Gizmodo: “Miserable battery life”
  • ZDNet: “One knock on the Evo 4G is it’s abysmal battery life. It’s pretty atrocious”

Although the above reviews of HTC battery life paints a gloomy picture, there is hope. GigaOM’s jkOnTheRun review says that “a little diligence is all that is needed to stretch the battery out all day.” It further says that,

I was concerned about battery life based on accounts I had seen on the web prior to using the EVO. Those concerns were unfounded, as I find the battery lasts all day with fairly heavy usage. Battery drain depends on how the phone is used, and with so many radios in the EVO it can be hit hard. With normal use the lowest the battery has drained on a given day is 11 percent left in the tank at day’s end.

HTC says that the Li-Ion battery provides up to 6 hours of continuous talk time. Battery life depends on the usage. For example, long backlight settings, vibrate mode, web usage, searching for signal, and others may reduce the battery life.

Reduce Brightness and Display ON-time

Another easy way to adjust display setting is to use the “Power Control Widget”. For convenience, one can have the Power Control Widget on the home screen and use it to adjust screen brightness and backlight on-time.

How To Change Screen ON-time? After each use of the phone, typically the phone screen will turn off automatically to save power. One way to save power is to set this  idle time before the screen turns off to be shorter.  To change this idle time,

  • Press “Home key > Menu Key”, and tap  “Settings > Sound & display > Screen timeout”

and then choose a shorter timeout value to save EVO battery power. HTC also suggests to turn off the screen by pressing the power button. The device will continue to function.

    I have had the evo for about 2 weeks. The battery is awful & i think its ridiculous that they would sell a phone you have to charge so much. Everyone needs to have a phone to rely on and you cant with the evo. The “task killer” will hurt the software running on your phone so dont get it. I rate the evo 2 stars. Im taking myn back. Thanks for reading. Hopefully it helps.

    Okay,well every Evo is different. I’m 13 and I always use my phone,& it stays charged like anyother phone. You just can’t have too many apps and keep the brightness low. And download an app called juice defender. It really helps. But don’t get that task manager crap,it constantly froze my phone when I used it. And the Facebook app drains A LOT of battery,so when you’re not using it,log out. Don’t keep too many widgets on your screens,or leave the screen on too long. Oh,and don’t put your phone on vibrate,that kills it .c:
    Hope this helped? (:
