iPhone 3G Battery at kozaru

So, I have a new iPhone. I’m not going to turn this into an iPhone-centric blog, but I will post some things I learn about this device here.

Starting with battery power conservation.

I noticed that I was draining almost all of my battery in a day, but that I was online a lot, getting apps and stuff like you do when you have a new toy. So it got me thinking as to how I could save battery. My friend gilmae mentioned that 3G sucks down the juice so i started from there.

1. Turn off 3G
I know, i know, it’s a 3G iPhone. But I don’t hear any difference in call quality or dropouts with GPRS, so i turn on 3G when I’m away from a WiFi signal.

2. Turn off Wifi
Unless you want to be online. WiFi actually uses less power than 3G, so use it first.

3. Turn Off Bluetooth
It’s off by default, but make sure. I used my BT headset with a more-or-less average result, so I’m sticking with the wired headset. You can’t push files with the iPhone BT anyway.

4. Turn Off Location
Not every app uses GPS, and if you need maps on all the time, you probably don’t deserve an iPhone. Switch this on with 3G (to refresh the maps) when you need it.

5. Turn off Push
Unless you’re a very active, very busy COE, you liekly don’t need to know the second an email comes in. Turn of Push and set your email to Fetch once an hour, or even manually. I do this with GPRS, because a few lines of text downloads quick.

6. Adjust the Brightness
Or have Auto Brightness On. Easy one.

7. Turn off EQ
Do you really need to bass boost songs on your iPhone? Turn off the equaliser, it uses up CPU cycles, and that means power.

All of the above should help somewhat with the battery life on your iPhone. This is what I use, but you may find other combos are better.
