Looking around at the battery stats and such, I noticed that cell standby was using most of my battery. That can be located here (assuming your phone is not charging): Menu > Settings > About Phone > Battery > Battery Use Now the reason the cell standby had been using more battery than other features... is because that's exactly what my phone had been doing. This was overnight, off the charger. Obviously it was doing nothing but standing by. So all seemed normal so far, but when I drilled into it I discovered: Time Without Signal: 54% That didn't seem good. Did this mean I was without service half the time my phone was running? I googled and came across an older thread for a different phone saying that if your TWS is around 50%, then it is probably due to your phone attempting to look for a GSM network as opposed to CDMA. Various "fixes" were mentioned. Toggling airplane mode. Or dialing *#*#4636#*#* and changing it from GSM to to CDMA somewhere in those menus. Well I didn't bother toggling airplane mode, and I looked for the GSM/CDMA thing, and my phone was already properly set to CDMA. So I assume that bit of information was particular to whatever phone they were dealing with (Eris I believe). I was curious, though, if Time Without Signal indicated ACTUAL signal loss, or was simply based on whether or not you had bars. I get 0-2 bars in my house typically. So I rebooted the phone in an area of my house where I tend to get 0 bars. I checked the Time Without Signal after a few minutes. Yep. 100% time without signal. Yet I checked in the network status and saw my typical signal-to-noise ratio here of about -100 db. I could also place calls just fine. I moved to another location in the house where I had a bar or two consistently, and the Time Without Signal percentage began to drop. Actual signal was still at my usual -100ish db. So my point is. To those worried about the Time Without Signal number: it is essentially as worthless as the bars. As for how this relates to Cell Standby's use of the battery, I am not sure. Just figured I'd inform you guys of my little casual test.
