Are you using push email?Here are the screenshots from a normal day without the plummet for comparison.
Two gmail accounts with the gmail app. Nothing else. The stock email app is disabled.
Poor guy, I'm sad i couldn't help, keep trying. I'm interested in a solution to extend my knowledge.
Don't give up buddy you will make it!
One quick way to rule out whether this is caused by the gsiff_daemon issue is to rename gsiff_daemon (or move it) and try running your phone without it for a while. As far as I can tell, the worst that will happen is your GPS accuracy will suffer. This post roughly describes how to do it.
I'm pretty sure my issue has been due to gsiff_daemon. Most of the time it seemed to be triggered when I would start Facebook and Facebook would use the gps to determine my location. So I tried turning off the gps except when I'm in the car. One week so far and no hot boots or runaway gsiff_daemon issues. Battery life has been good. I guess this will work until Samsung pushes out a fix.
I get this battery drain maybe once a week, a friend of mine also gets it occasionally, It is very unlikely that our phones are from the same batch, because he got his 2 weeks before i got mine. It seems to be a more widespread problem than we think, and i hope samsung, or someone on XDA, can figure it out and fix it.
Hey guys - I'm now chiming in too. I am back on Android after being away for over a year, but my last android phone was a Galaxy i9000M that had this SAME bug and I had to root it to get it to stop. Now, after a month of owning my i747M, this has done it twice in a week and a half. I charge it to 100% before bed, leave it on my night stand, and wake up 9 hours later to a 2% battery and the cellular radio has been awake for 9 hours (even with wifi on). I've rooted after it did it the first time a week and a half ago...just in case, but am I gonna need to rom this to make it stop?
I can't believe Samsung STILL has this bug after several models of Galaxy and a year and a half.
What are the odds of me having two units in a row with the exact same problem, which does not appear to be widespread?
The bad news is that I am past my 30 day exchange window.
Whats your screen on time, battery stats indicated a deep idle of only 2hrs.
And damn your cell standby % is huge. When I had the cell standby bug it only rose to about 15%.
IMO that high cell standby is not normal even with the bug.
Here's another sample with a Better Battery Stats log attached as well.
I'm going to do another test tonight with airplane mode enabled + another BBS log.
