refurb - battery life after root and rom

[apinkel]

I got a refurb phone and it chews thru battery roughly 3 times faster while on 3G than my original phone (battery life on wifi is the same or better than the original phone). Is it possible that my battery life issues are due to running a VD rom with a non-VD radio or does 3G just stop working altogether in that scenario?

Some background...

The GPS died on my original optimus S so I went in and swapped it for another. On the refurb I checked for any updates (but I forgot to check if it was on VD).

I then rooted it using gingersnap... it failed a couple times with some kind of permission issue but I finally just left it run and eventually (I don't remember what I did) it was successfuly in rooting the phone.

I loaded TR 1.8.3 and updated profile and prl... and it works great except the battery life on 3G.

Posting back for anyone else who may run into this...

Since I didn't verify that I was on VD before loading TR 1.8.3 I used KP500 to force flash VD onto my phone to insure that the radio was VD as well as the ROM. I followed the instructions in the revert thread (thanks sfhub)... http://forum.androidcentral.com/lg-...70vc-vd-using-kp500-diag-mode.html#post655188

My battery life is still poor. It appears that the radio in my refurbed phone is about 1/3 as efficient as my original. I'm able to manage it by using Green Power Free (similar to juice defender) to only turn on 3G data sync 5 minutes every half hour.

3g drains your battery very fast I use an app called "Juice Defender". basically it just shuts of your 3g with the screen but turns it on on a timer you set to check emails, facebook, etc... It gives you a gauge to tell you how much it increases you battery life too and mines says x1.74 and i believe it. Its a great app and I'd look into it!

I'm using Green Power Free instead of juice defender to shut off 3G data sync.

I probably should have tried juice defender but from reading the description it sounded like it had more stuff then I needed and I like to keep it simple when possible.

juice defender works great without having to mess with settings.
