A day in the life of battery tests [iPhone]

i spent the day testing out the resilience of my iPhone battery, and thought i’d put together a timeline to show how things progressed. for the purposes of this test, i decided to keep every known battery draining setting turned on in what i consider a full on stress test.

here are the details:

  • 3G is on
  • push notifications are on for foursquare, AIM, and Yahoo! Messenger
  • push mail is turned on for both a Yahoo! Mail account and an Exchange account
  • location services are on

i took screenshots throughout the charging session, here’s what i came up with:

iPhone charging timeline

[block I]

3:30 pm — i started a charge, the battery was at 75% when i plugged it in

3:49 pm — no change after 19 minutes, however the “charging” symbol switched to the “plugged in” symbol — the phone thought it was fully charged

4:04 pm — still no change, but the phone has now reverted back to the “charging” symbol

[block II]

4:16 pm — still no change. at this point, i unplugged to run errands

5:30 pm — returned home from errands, plugged back in to charge. during my time away, the battery depleted 50%

[block III]

5:51 pm — within 21 minutes, the phone is back up to 75% charge

6:48 pm — nearly full charge. i checked on the charge flow, there were no hiccups (as witnessed in block I)

7:47 pm — nothing worth reporting during this hour, but i thought i’d add this in just to show that there were no further abnormalities

i’ll test traction throughout the day, tomorrow.
