I know some people have problems with battery usage. I figured I’d try and see what kind of time I could get out of my phone on a typical usage day for me. I am going to TRY to avoid just fiddling with it, only texting, calling, and checking mail/web when not at a location that provides those services ( ie: websites on my work computer or email at home ).
Check after the jump for details. The “day” is starting at noon only b/c I was out with my realtor earlier this morning and wanted to get the battery to a full charge before doing this.
These are the settings that will not be changing during this test:
- Wifi, Bluetooth & GPS/Location services all on
- No PNS apps running ( logged out of IM )
- Google Push sync for contacts & calendar
- Google mail check every 15 min
So, here we go:
- noon – 100% battery
- 12:35pm – checked contacts …still at 100%
- 2:17 – 1 text message, app usage: 96%
- 2:45 – 3G to web – downloaded new wallpaper for the lockscreen ( for whatever reason wifi wouldn’t connect )
- 2:45 – 2:50 – text messages received: 4 sent: 3. Batter at 93%
- 3pm: router was jacked – restarted it and connected to wifi
- more texting 2:50 – 3:15pm – battery now 87%
- 3:51 – 86%
- 4:40 – 85%
- 5:45: 10 min phone call
- 6:50 5 min phone call, some email checking – battery 74% ( this is the 7 hour mark and but 25% of the battery is depleated: the iPhone claims 1 hour and 26 minutes of usage with and 7 hours 11 min of standby time since the last full charge ).
- 7:30 – restarted phone 2x – to recover ECID.
- 8pm – 20 min call. Battery at 66%. ( 8 hour mark and the phone is at 66% now. That’s a pretty big drop of 10% in the last hour, but I suppose 2 restarts and a 20 min phone call can put a drain on the battery )
- 8:45: 5 minute phone call, 10 minutes web browsing: battery 60%.
- 9:30 – 59%
- 9:47 – 11pm. Lots and lots of texting. Battery at 48%. Seems that 3G usage kills the battery more than anything else.
- 11:30pm – battery at 46%.
Seems like my typical usage could take me through a full 24 hours without a charge. I’m going to let the iPhone run all the way down until it is crying for a charge and will update this again then.
Update 1:
It’s now 7am, and with my alarm, and having hit snooze once, and checked an email my battery is still at 30%. So, it drained 16% in 7 hours of standby. The usage meter calims the following:
Usage: 3 hours 40 minutes
Standby 18 hours, 47 minutes.
I guess the standy time and the usage time overlap somewhat, they have to, the phone hasn’t been off the charger for 22 hours yet ( only about 19 hours ). To note I do have between 4 and 5 ( full ) bars at home, work and in between. I’m not really in a place where my phone struggles for signal, and in my 6 hours and 50 minutes of recorded call time, not 1 dropped call. So far I’m quite happy with my purchase.
Update 2: It’s now 9:45 am and my phone just hit 19%. I’m giving it to 10% before I plug it in.
Update 3: It’s now 11am and all standby since arriving to work at 8:35am. The phone is at 17%. 7% to go before I plug it in. I’m actually pretty impressed, it looks like it will last a full 24 hours with some pretty heavy usage in short spurts. This does put my TMobile Wing battery to shame and it got much less usage in terms of data b/c edge was so painfully slow, and wifi setup on it was terribad ( yes, that’s a word…it’s like terribly bad, in a single word ).
Update 4: 12:45pm and the battery is at 15%.
