5 steps to boost your iPhone's battery life
The reason why the iPhone's battery drains so quickly is very simple: by default, iOS is tuned to give you the best performance — graphics, speed, usability and the contextual abilities of the apps. Frankly, app developers were obviously not supposed to think about the battery at all. But you care and so do we, for a very simple reason – power efficiency is part of mobile security.
1. Turn down screen brightness to 30-40%
Go to Settings -> Display and Brightness in the menu. Switch off the “auto-brightness” mode and set the manual value to approximately 30% of the maximum. Then switch your iPhone off for 5-10 minutes. Next time you turn it on, you probably won't even feel the difference. But, your battery will!
2. Switch off Bluetooth
When you turn on your brand new iPhone for the first time, iOS automatically turns on Bluetooth. Why they decided to do it this way is a complete mystery, but long story short – if you're not using a BT head-set or an in-car system on a regular basis, you'll want to switch BT off.
3. “Flight mode” is valuable even off of an airplane
The problem is that when there are no base stations in the proximity of your iPhone, the process of searching for those towers consumes energy, as if your iPhone was Tony Stark's outfit. By switching to “Flight mode” in the areas where you know for sure there's no cellular coverage you could significantly increase your phone's battery life.
4. Don't let every app track your GPS location
Some apps (most of them actually) track your GPS location in real-time. Of course, some of the apps require location services to be switched on as it's within their nature – nobody would use FourSquare a navigation app if they were unable to track your exact location in real-time.
5. WiFi consumes less than 3G – what does this tell us?
Actually, 3G data traffic is the main energy “vampire,” especially in overcrowded parts of huge cities. The math is very easy – if you use WiFi networks instead of LTE/3G, you will immediately see a boost in your battery. Turning off LTE and sticking solely to 3G can provide your phone with an additional boost as well.
