I posted in the battery forum, but this is a bit more specific and I feel like deserves a thread title in hopes of a response. Basically, the deal is that when I'm talking on the phone, the battery is dropping rapidly. Here's what happened: I noticed yesterday that battery life was horrendous *when making a call*. With the phone idle, drain was about like my EVO4G -- not too bad. The phone was at about 40% and I made about a 5 minute phone call. It dropped to about 20% battery left. I charged for a bit (didn't have a lot of time) but got it back up to 50%. I made another 6 minute phone call and the phone dropped down to 16% and then a couple of minutes after I hung up it dropped into "saver mode". I charged again during another break and got back to about 50% and made a call on the way home... This call was 16 minutes and dropped my battery to 24%. These are all according to battery monitor widget. In looking at my battery use through the about phone menu, everything looks normal but I can CLEARLY see when I made the phone calls as the battery drain on the graph looks like a straight cliff. Today, I've made three phone calls totaling 21 minutes. Each was about the same length -- 6-8 minutes. There are three very distinct cliffs for each one where the phone dropped 10%+ for each call. I've played a few minutes of games and sent a few texts and emails -- nothing any more than I did on my EVO 4G. I hit the web for about 5 minutes as well. No 3D at all. I'm sitting at 46% after 8ish hours of having the phone on. I've had wifi on all day and had a wifi connection for most of it... I think it was EarlyMon who had a bad radio or one of the other mods. Is this an indicator of a radio issue? Note that I have pretty much every battery "saver" turned on. Screen brightness about 20%, data always on is OFF, no google backup/restore, check for updates off, no facebook/twitter/stocks/news, turned off wake up animation... Update - Turned off wifi around 40%. No calls but the 3G radio ate the battery down to 14% in about 2 hours. My signal runs around -95dBM at home. It was always somewhat of a drain on my 4G, but nowhere near this bad. At this point in the day my EVO would be in the 65-75% left range so something must not be right with my radio. Or Something.
