Battery fix from Evo board.....Check it out!!!

Since Verizon is a CDMA network, this is what our phones should run off, however when I did this test from the EVO board it showed that my phone was actually on a GSM signal and since Verizon isn't running that it searches for a signal that isn't there thus wearing the battery down. So here is the post so that all my Incredible brethern can enjoy better battery life.

YOU DON'T NEED A HARD RESET EVEN. I CAN CONFIRM, ALL I DID WAS THIS:

press HOME, and bring up the dialer. Dial *#*#4636#*#* (Do not press "Call"). After a second, it should bring up the "Testing" menu.

Go into Phone Information, press MENU, and tap "select radio band." You should experience a Force Close, don't panic, this was supposed to happen. Scrolling down shows that the preferred network type is GSM auto (prl).

What this means is that even though you are connected to a CDMA network, your phone is trying to find a GSM network, preventing the radio from sleeping, and causing excessive battery drain.

Remedy this by tapping GSM auto (prl), and changing it to CDMA auto (prl).


Now your done, your TWS should drop dramatically, and you should experience much better battery life!

Mine already is CDMA auto PRL, then when it force closes it changes to GSM auto PRL, so i think its the force close causing the problems... maybe.

If you do this once, then go back and do it again after that force close it resets back to GSM and you have to change it again, so i'm not 100% sure this does anything imo.

But lets see what other people think, as I could be totally wrong,

I'm not sure how many people this would help anyhow. Many people report their battery going very long periods of time in "paperweight" mode. It's when you start using data/gps that that battery drains much faster. This would only help people who see significant drain when the phone is just sitting there on the table.

Personally, when I just leave it sitting there, I have wifi connected (which turns off mobile data) and wifi set to never sleep, I barely lose any battery at all if I don't touch it.

It's a visual glitch (from Hero days as well). That being said, this usually doesn't affect every phone. If your "time without service" is high, this fix will typically help. :)

If you reboot, it changes it back too. :( Mine was NOT on CDMA (PRL) It was in fact on GSM. Hopefully it will increase my battery charge time. We shall see.

Correct, this needs reapplied each time you turn the phone on.

Here is the easy fix to all our battery problems that we can learn from the EVO.
We can peitition HTC to allow us to run the graphics processor at 30fps. You know, slow down the user interface, the Sense UI, the 2D and 3D graphics. That will conserve a lot of batttery

HTC EVO 4G performance capped at 30fps

and

HTC EVO 4G's graphics capped at 30FPS? -- Engadget


LOL.

This is nothing more than a case of ignorant journalists learning something they didn't know and mistakenly believing it has something to do with the Evo since they discovered it with the Evo. Android OS runs at 30fps, always has with every single version and every single device.

So there seems to be conflicting info in this thread. Could someone please put down in one post, what is correct?

Here is what I have;

BEFORE I force close, mine is set on CDMA. AFTER I force close, it says GSM and I have to change it to CDMA.

So, my question is, what is correct? Before or after force closing?

More important... check your time without signal. If it's high, you need to do this fix. If it's low, you don't.
