Any iPhone user will definitely use the iPhone not just as a phone but alot more – games included. And with more openGL 3D applications to play with, iPhone’s battery life is seriously taking a big hit. Just imagine using your iPhone on a train journey with all those GPS, Location aware features, games, internet and a lot more.
The idea is to conserve the battery charge rather than use a 3rd party add-on which might cost like $100! While we all know the basics of conserving iPhone’s battery, let me list them here :
Monitor battery usage for each app using iPhone’s hidden Numerical Battery Indicator
- Apple introduced this hidden feature (Numerical Battery Indicator) in iPhone 2.0 firmware. All we have to do is enable it using BossPrefs to change the concerned plist file. BossPrefs tool is a nifty little tool to achieve enhanced productivity the Graphical way! You have to use Pwnage to jailbreak your iPhone and install BossPrefs app in Cydia.
- All you have to do is monitor the battery charge as you use your favorite apps (which you use for longer periods and more frequently). This way you can save your much needed battery by choosing the right app to whale away your time with 🙂
Turn Bluetooth/WiFi/3G off unless really required
- That makes complete sense. WiFi / 3G or any radio (bluetooth, IR) generally tends to drain power. Use them with caution! Efficient usage of these radios may help you achieve better battery.
- Though auto brightness is on by default, you might want to play around with the display brightness slider given that it plays a major role in deciding how much juice your battery can hold and for how long!
Auto lock Your iPhone
- 1 minute is the best but don’t pull your hair if you are performing SSH related tasks on your computer/iPhone, you must then set it to ‘Never’.
iPhone battery Charge cycle
- Well, time and again it was told that Li ion batteries just don’t care how much they are charged not requiring a full charge cycle but it is always a good practice to wait for the battery to die completely reach the threshold level 10~20%(red indicator) (thanks Dizzy and David) and then recharge it.
- It is also a good idea to recalibrate your iPhone battery every few weeks. All you have to do is let your iPhone run out of battery charge completely and then charge it fully. You now know what to do at home, play lots of games on your iPhone and then leave it to charge 🙂
mail.app Fetch Cycle for Email
- If you choose a fetch cycle of 15 minutes, the battery drains power at the same rate. Your best bet is to go ‘Push’ (MobileMe or Exchange). Forward your Email (Google, Yahoo,….) and expereince Me.com for a battery savings push alternative!
Use your headphone for listening to music, watching movies
- Well, this is not even a tip, more like common sense. Ignore it completely as we all know how to enjoy the stuff on the iPhone.
