Extending Battery Life - Success...

[eric3316]

how did you uninstall talk "completely"?

You are both talking about 2 different programs. There is Google talk that comes on the phone, and Google Voice that you need to install and does not come on your EVO.. Google voice does not kill the battery at all so not sure what the other poster was talking about.

It is Google Talk you want to shut off. As far as I know you cannot uninstall that.

Here is my graph from the past day and a half or so...wasn't paying too much attention to my usage but I would say that it was light/moderate...will do the same thing tomorrow and monitor usage...

so unplugged at about 315 sunday after noon and at 9% approx at 915 monday night

Update: Disabling BlueTooth and GPS doesn't have much effect, have been keeping them on/standby always, just to simplify my use.

Thanks for this wonderful information! So task killers don't help? I've been using Advanced Task Killer (free) and I don't know if its been saving me battery life or not. I'm not to try closing it and see how it works

How do I find out what is keeping my phone from sleeping? I am getting the following:

Uptime: 113:05:xx
Awake Time: 110:18:xx

Looks like my phone has only slept maybe 3 hours out of 113?

This has made the largest improvement for me, from another forum thread-
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!

My phone settings are pretty much stock with the exception of changing the "Roaming" setting in "Mobile Network Settings" to Sprint Only. That change took me from about 10 hour battery life to 24+

Hope this helps...

How does one go about looking up the TWS (Time Without Service)? I found it once before (it was 39%!) but I have not been able to locate it since. I'm getting very poor life... like maybe 4 hours, but I just found out about the google talk application last night and I turned it off. We'll see if things improve today.

Menu > Settings > About Phone > Battery > Battery Use > tap on Cell Standby at the top.

Thanks for the info IPvFletch... Mine has improved from 39 to 2% after updating the PRL.

Download "Spare Parts" > go to battery history > change from 'other usage' to 'partial wake usage'

That will tell you what's been keeping the phone awake the most. Look for something that sticks out to you. For me it was something to do with the calendar.
