Saving iPhone Battery Life
On the eve of the new iPhone firmware upgrade (2.1), I still think it is a good idea to share my thoughts on conserving iPhone battery life.
Sure, if you talk a lot, you are probably out of luck. You could also follow Guy Kawasaki’s Art of iPhone Battery Life, but it’s a little involved for me. For those of us that want an easy solution and seem to use our phones a normal amount (and probably have landlines at home and the office), there is a pretty easy solution:
Turn off Wi-Fi!
Seems silly, right? It is, but it works. If you aren’t in danger of going over your 3G data plan, turning off wi-fi appears to be a huge boon. Empirical evidence? Hell no, just observation.
During the first 3 days of getting my new phone, I was too lazy to look up the crazy password that my wi-fi encryption spits out, so I stuck with 3G. The same is true when I was at the office. But after a few days, I decided it was time to dig up my password and let wi-fi take over. The morning after a new charge, my phone was dead. Yet, my usage pattern for talk and surf hadn’t changed. The only wrinkle was the decision to set up of my home wi-fi account.
Since then, I have disabled wi-fi, and battery life has returned to an acceptable (maybe even good) level. Give it a whirl, and let me know if it works for you.
