Overheating, Charging Problems
One morning, as I was taking my Galaxy S2 off the charger, it was quite warm and the battery was at 10% - after charging overnight! How could it be that I purchased a complete piece of junk like this? How dare it get hot, and how dare the battery not charge on a 2 month old phone?
Well, as it turns out, I'd left my security camera software running, and it had been streaming video (behind the locked screen) all night (on WiFi). Streaming video chewed through the battery and caused the CPU to warm up.
I have a feeling that a lot of these are growing pain problems; getting used to how the apps are handled on the devices. Leave a CPU intensive program running, and duh... it's going to get warm.
