Today after I got back from lunch I noticed that my phone's usual green light was now red, and the phone had a message that popped up reading that the battery was almost flat, so I clicked the usage monitor and it read out that most of the usage being idle (I believe it was 70% idle usage, and the rest was messaging and whatever else I had been doing, like usual). So, I turned it off until I could get to my backpack with a charger in it, so that I could at least turn the phone on real quick to make a quick call if I needed to. Well, I completely forgot about the charger until I got back home from work, so when I got back home I turned the phone on and it read 80% battery capacity left. Taken aback, and curious, I decide to leave it on and NOT charge it, just out of curiosity to see how long it would take for the phone to remind me that the battery was almost flat. Well, it's been over 4 hours now, and it just only an hour ago dropped down to 70% battery usage. It's been idle, checking email and chatting a bit on g-talk during those 4 hours. Normal usage, no bluetooth, wi-fi, or GPS. So my question is, what the heck happened? clearly the battery was not about to go completely flat earlier today, because it's still got plenty of charge! There was no severe change in temperature, and no abnormal usage of the phone by myself (used it just like I always do) Now, I've seen batteries that seem to get a little extra "boost" when they are shut off and turned back on again, but it's been 4 hours now since I turned it back on, and it's still got alot of capacity left. I'm suspecting that somehow the phone somehow miss calculated the battery capacity and put up the dialog for me to quick turn the phone off or re-charge it. Yall got any ideas as to what happened? Anyone had this happen before? Is the battery level meter really accurate? this is the first time this has happened. I usually put it on charge every night.
