Ive noticed lately that my phone is always pretty warm. I downloaded a temperature sensor from the market to keep an eye on it and most of the time it about 100-125 degrees Fahrenheit. I usually notice this after its been sitting on my desk for a while, not using it or charging for a bit. I definitely notice it when its in my pocket. If Im using the phone or gaming for 15 minutes or so, it can jump to over 125 degrees. A heatwave hit during the summer, if my phone was over 100 degrees, it would not charge unless it was next to the AC. I have 3 batteries for my phone, some days I can by with one, other days I use all 3 and still need to charge. Is this good or bad? I know electronics can get pretty hot or overheat, but its drains the battery much more when its hot. Is there an app that can monitor whats chewing up the most system resources?
