Hi, all. Purchased my Vibrant back in July and always had some battery issues. I figured I'd try one last thing before asking T-Mobile for a battery replacement, so here's what I did. Can someone tell me whether or not this seems normal?
Two days ago, I ODIN'd to JFD to start completely from scratch, then flashed Bionix-V 1.3 non-TouchWiz edition (wiping in the process). The flash was on a completely full battery (plugged into AC, unplugging for the first time after booting into Android).
Here are my usage stats for today:
WiFi off, GPS off, Bluetooth off, auto-rotation off, 3G enabled, brightness around 25%, power saving mode enabled
Gmail/Contacts/Calendar - push, Exchange email - every 15 minutes
Google Talk logged in the whole time
No other syncing applications
Usage consisted mainly of web browsing and around an hour of listening to music through PowerAMP
Charged to 100% overnight
Unplugged for 5 hours, 30 minutes (8:30am to 2pm)
Battery stats: Display 97% (display on 1h 35m), cell standby 3%
Final battery at the end of period: 30%
So, does anyone else get similar battery life on a nearly untouched installation of Bionix? A 70% battery loss with only 1 hour and 30 minutes of screen time seems a little high to me.
That seems like a lot. Try downloading an app called battery left from the market. Charge up to 100 percent and let the app calibrate. It will show you how long a full charge should last. With moderate use I get about 15 to 20 hrs of life with bionix.
Exchange Sync? With what app? I've heard that touchdown is a really bad drain on battery and refreshing every 15 minutes might be a problem. Poweramp for an hour probably cost you 20% battery as well. I'd give a few more cycles to judge your battery life. Compared to my phone, been off the phone since about 8 AM, 20% battery now around midnight. This included 30 minutes of music with the TW player, about 3 hours of display time, a few photos, and about 5 minutes of phone calls, 15-20 text messages. Also some web browsing on 3G and wifi.

Just the Samsung Email app. And I don't think 15 minute polling for new email could cause that much drain... that's something I only enabled recently. This is after a few full battery cycles.
I've also never observed PowerAMP using much more battery than the stock music player.
Sounds like your phone is getting much better battery life.

An hour of PowerAMP drains about 3-4% with flipping through songs, and I have been using this app for several weeks.
Check out system panel also, see what apps you have running in the background.

As I mentioned, this is a fresh installation of Bionix-V 1.3-- I haven't added on any apps that could possibly be responsible for the battery drain. I've used System Panel in the past to evaluate battery issues with little success.
I've had bionix-v 1.3 for about 3 days now.
This afternoon i pulled it off the charger at 90%. Now, 7 hours later, i'm at 69% with:
display: 79%
cell standby: 16%
phone idle: 4%
Today was pretty light use though. Just about 20 texts, 30 min. of web browsing, 5 min. on phone calls. I also put my display brightness down all the way and freeze a few apps using TiB.
Normally though, i make it through the entire day (18 hours) with one charge and what i consider to be 'average' or medium usage.
I am finding that playing audio on my Radar seems to drain the battery pretty fast. I first thought it was because i was streaming music from Zune, but even when playing audio locally the battery drains much faster than my HD2 running WM6.5. For instance i charged the battery to 100% then disabled data and only played music at volume level 5 for 1.5 hours and the battery was down to 80%. Is this normal?
Just put an mp3 (like with the Walkman app), on repeat with the volume at zero. You can safely power off the phone and it will not sleep off death. I've been doing this all day and works just fine. It also has negligible impact on battery life. I'm on track for 5.5 hours screen time and Walkman constituting 3% battery usage.
Hi,
yesterday I did a test running(gps) for 20 min listening music (bluetooth) and I had a battery drain about 10%.
With this consumption a full charge will last only 3 hours and 20 minutes.
This is good?

Yes, around 20% at hour.
What is the standard battery drain per hour for streaming music over 4g?
Do you worry about music or audiobooks battery drain at all?
For me it looks like draining 4-5 % per hour
