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:
[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.
