Baterry Usage Question: What is ____

[Grizaje]

Well the first 2-3 days I was having Horrible battery usage. Yes I was using 4g, gps (Trapster app is AWESOME) and data background, sync, etc etc etc

now I turn off 4g, wifi, gps, etc like everyone else here but I still have a few more questions about battery usage.

Currently my Android system is 57% usage
my 2 biggest usages is that and Cell standby

now when i go to setting>app>running services I have the following running:

Calender (Obexservices) - wtf is this, do I need it on? I dont use calenders

Calender (ConnectivityService) - same as above, do I need it or forcestop?

Voicemail (CM_Service)

HTC DM (HTC DM services) - ???

HTC IQAgent - ???

com.smithmicro.com (DMServiceApp) - ???

Swype + Pocket Empire

---------------

I have gone through every other settings and turned off most background data running stuff off, syncs off, roaming off, so what else can I do to tweak my baterry usage.

I personally shut off everything in running services that I don't use, also, check your google talk settings and make sure it isn't running all of the time and killing your battery. I get over 24 hours on a charge so I hope this helps!

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!

THE RESULTS SPEAK FOR ITSELF:

***NOW, WE JUST NEED TO GET THIS TO STICK AFTER A PHONE REBOOT!***

I'm lost when you say

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

How do I tap GSM auto (prl)?

How to I change to CDMA auto (prl)?

What is "prl"?
