The phone is about 4 years old. Has been great until the past 3-4 months. Figured a battery issue. Replaced the battery last week. New battery has not seem to have any impact on this annoying rebooting. And, battery life is the same as the old battery - roughly 8-10 hours no matter the use. Clearly, something else is going on.
When the phone was new; generally got 18-28 hours of battery life.
