I upgraded from a Cingular 8125 to a 8525 6 days ago. I was shocked on how bad the battery life was on the first day I had it. Over the last two days I decided to run some benchmark on battery life.

3G on using UTMS/HSDPA – Bluetooth – Direct Push Email
Yesterday my phone had a full 100% charge at 9:00am, by noon it was down to 50%, by 4:00pm at was at 10% and ready to die.

3G off using a slow GPRS – Bluetooth – Direct Push Email – Same apps running as above
Today my phone had a full 100% charge at 9:00am, by noon it was down to 90%, by 5:00pm it was at 80%.

It almost seems that when UTMS is on with Direct Push Email it drains the battery as if you were talking on the cell phone the entire 7 hours before it goes dead. I have read in the forums that a lot of people have the same issues.

I wonder if a firmware upgrade will fix this or if we are stuck with horrible battery life on the 8525.
