iPhone Relief Part I: Battery Life
I know I’ve been complaining a lot about my iPhone. Apple products are supposed to just work — that’s their brand — and this one just hasn’t, at least not for me. But I’m seeing the light at the end of the tunnel of technology torture, and just about everything’s working now, if not the way I would have liked originally. I’m going to recount in the next few posts my trials and tribulations and how I overcame them.
Recall my most recent complaints: (1) abysmal battery life and (2) broken Microsoft Exchange integration.
I was sometimes getting less than 5 hours of battery life, even after Apple replaced my unit with a new one. Firmware 2.1 plus some more prudent battery conservation practices have all but solved #1. I’ve read too many articles, blog posts and discussion board threads on this to recount. Plus, I’ve finally succumbed to logical suggestions — most of which I daresay I had heard already — from BW and ES. Here’s what’s worked for me:
First, I’m only fetching data now, and only hourly. Such is the disappointment of and lowered expectations in performance of the iPhone 3G that the very reason for buying it — push — is what must be disabled to provide more reasonable battery life. I’m not even upset that I don’t get push, because it was working so poorly — that battery-killing wheel seemed to be spinning constantly — and I’m so grateful for longer battery life.
Second, I’ve slightly reduced the number of accounts from which I’m fetching data. I have work Exchange, Yahoo, Gmail and MobileMe accounts. Instead of fetching data from all of them, I’m forwarding Gmail to Yahoo and fetching from Yahoo. I use MobileMe only for calendar and contacts syncing, so I have it set up but never check that email. And I’m even fetching from my work email account. I came to terms with the fact that I don’t need push email to distract me in meetings, and I already get push when sitting in front of my destop with Outlook open.
Third, I’ve turned brightness down fairly low. Even with a protective film on the glass, it’s still bright enough for me.
Fourth, I’ve left Bluetooth and Location Services on. I use my Bluetooth headset to and from work every day, it’s too much of a pain to go into Settings to deactivate and activate it repeatedly, and I’m not convinced it’s a drain on the battery. For Location Services, much of the time I have this off, but I just end up switching it on when prompted when using Google Maps or some other geo-aware application that calls for it.
Finally, I’ve left both 3G and Data Roaming turned on. As eBay alumnus Ryan Spoon notes, push has a much greater effect on battery life than 3G. I know at least one other iPhone 3G owner — ES – who switches off 3G not because of the perceived battery life drain but because he believes the network is unreliable and results in dropped calls. I’m accessing the Internet often enough that I want the speed from its being on all the time.
The net effect? I can go over a day without recharging. And I don’t live in constant fear of a sudden drained-battery-induced shutdown. Frackin’ fantastic. Reasonable battery life? Check!
Next, I’ll bemoan the complete failure of Exchange integration, my data sync requirements and then the awkward but functioning solutions I’ve devised.






This is very wonderful to have. Now I can just go in and set all of my stuff to your settings as described above without having to test it all out myself.
Do you have a list of favorite iPhone apps blogged somewhere? I want to know what I should go out and immediately purchase/download when I (finally) get my iPhone.
