Is the battery life of your new iPhone 3G disappointing you? Try these three tips to increase it’s daily usage before having to recharge. I went from getting about a days worth of moderate usage to two days easily only doing the first two tips – the third is for when you need to squeeze a little extra juice out while away from a wall outlet or USB port.
1. Turn off PUSH
Turning off PUSH support will go a long way to improving battery life.
Decide how often you really need to check for email (I can live with every 30 minutes) and set it to Fetch accordingly.
You just have to launch the Mail application and it will check for email anyways if that time frame isn’t good enough but at least it won’t be checking in the background all the time, slowly killing the battery.
You’ll find this setting in the Settings menu under ‘Fetch New Data’.
2. Turn off Location Services
Also known as ‘the GPS’ setting on the iPhone, it’s turned on by default. Turning it off is probably the single most battery saving thing you can do short of not using your iPhone.
This doesn’t mean that Google Maps will stop working. It just means that when off, Location Services isn’t powering the GPS and looking for a location. If you launch Google Maps or any other location aware application, the iPhone will turn on Location Services.
Keep in mind, once turned on by one of these apps, it won’t turn back off by itself when the app is closed so you may have to keep turning this off.
This setting is located in the Settings/General area.
3. Turn off 3G
Desperate to keep that phone alive a little longer? Simply switch off your 3G to gain a few more precious minutes of juice. Of course, surfing will be slower since you’ll be using the Edge network instead, but this tip is really meant if you need to get a few more minutes of life for a voice call before the iPhone shuts down.
Depending on where you live/work, this may simply be a better option anyways if your 3G reception is spotty.
You’ll find this option under the Settings/General/Network option.
