When I bought my phone in October of 2011, it came with gingerbread 2.3.3. The battery life was terrible and the phone was hot without any use at all. Shortly after that, I got an upgrade to gingerbread 2.3.4. The upgrade corrected both problems. This week, my phone upgraded to 2.3.5. Once again, my battery life is terrible and my phone gets hot without any use at all. Is anyone else experiencing these problems? I did a cache clean after the new upgrade.
