HTC EVO Battery Drain Signal Fix

EDIT: Only take the time with this if you are experiencing crap for battery life, as it seems that many people already have their preferred network set to CDMA auto (PRL) Seems there a select set of phones that came with GSM set as the preferred network, so don't be surprised if yours is not.



This seems to only be a problem with some of the initial EVO's that shipped, and it was possibly fixed by Sprint OTA, but I cannot confirm that.

Download a marketplace app called Network.

Look to see what your preferred network type is. If it is CDMA auto (PRL) hit the home key and uninstall the app, as it not needed anymore.

I found that on my phone, my Preferred Newwork was set to GSM auto (PRL) so the phone was looking for GSM first, which completely drained my battery in less than 4 to 6 hours.

If you find it set wrong, ONLY change that Preferred Network setting to CDMA auto (PRL) and hit the home key to exit. Don't mess with anything else.

I suggest a reboot, then run the network program again to verify that the setting took.

You should then be able to uninstall the program. Even after a hardreset I did, the setting stayed, so that is why I am thinking Sprint did something OTA, but am not sure.


Sidebar:

My personal opinion, stayaway form Task Killers! They should not be needed with this phone. If you have installed a program that was not made well, and does not close properly etc., that is one exception to having a Task Manager to manually kill things, but I urge everyone to NOT do any autokill configuration if you want to be a happy EVO user.

Re: HTC EVO Battery Drain Signal Fix

It depends on what you have running and installed.

Many people are finding a huge killer to be the Talk app. I don't use it, I think it is a google messenger app. Once you sign up for Marketplace, the Talk app signs you into the app automatically, so it is like having the old WM Messenger app open and runnning in the background all the time,

Go into the Talk App and hit menu, then go to settings and tell it to log you off and to not automatically sign you in.

There is also talk about Flickr accounts being bad.

You need to also removed any widgets that keep you connected to Facebook or Friend Stream etc.

Here is another forum link that goes in depth:

There is a Sedio 3500maH battery coming out sometime!

I was joking, but nice info. I've already done these things but should be helpful for others.

Re: HTC EVO Battery Drain Signal Fix

Also to settings acc & sync, if you have Facebook HTC Sense tap on it and uncheck Sync Live feed. I noticed that my phone was syncing all the time and my sync settings are set to every 4 hours. After that I have noticed some improvement.

Re: HTC EVO Battery Drain Signal Fix

I disabled all auto syncs, google stuff set to manual sync, weather to 3 or 4 hours (I forget). Lasting me nicely, even with all the goofing around.
