This phone suffers from wakelock issues which keeps your phone awake. Only way to combat this is flashing a different kernel onto your phone. I did just that and my issues are fixed.

My DNA has been suffering from wakelock issues. Two in particular. wlan_rx_wake and msm_hsic_host. The first I have nailed down to the wireless routers at my office. So now I simply leave my phone in 4G while I'm at work unless I'm streaming Slacker. The second wakelock has been more annoying and much more of an issue/battery killer. This wakelock has plagued me for about 4 weeks now. There are numerous threads over at XDA that discuss it and to croppz statement the common fix is to flash a different kernel. However, as I am hooked up to my corporate email and run off of my company's IT policies that's not really an option for me.

So, last night I sat back and thought about when the wakelock started peaking it's ugly head. I've had the DNA since release day and only had the wakelock issue for the last 4 weeks and the only difference I noticed that correlated was an increase in SIM card errors. I get at least one SIM card error a day and normally just restart the phone to clear it. Last night, I decided to actually pull the SIM card and re-seat it. Today, the msm_hsic_host wakelock has been in check. Before it was literally running anytime I turned the screen off, so if I had the screen off for 7 hours the wakelock showed 7 hours. Today though, the screen has been been off for 8 1/2 hours so far and betterbatterystats is only showing 50 min of the wakelock. While I still think that high, it sure beats the 8 1/2 hours that it was doing before.

Glad you got it worked out. Mine was running out of whack for a while but now it is doing great. I still have a moderately high wlan rx wakelock but that is because we have like 8-10 devices connected to our router haha.

Oh and for checking wakelocks, better battery stats is worth the buy. Gsam is free but its data is also inaccurate as far as wakelocks go.
