Battery life is something very important when it comes to a mobile phone and laptop. It is very important that that the battery life does not decrease so its best to increase the battery life, so that the device lasts longer.
I have mentioned details about ways to increase the battery life of devices like a mobile phone, laptop and camera.
Optimizing system settings
When it comes to laptops they require a lot of charging and as the battery gets older the cycle also decreases. In order to increase the battery life of a laptop you need to optimize the system settings of the laptop. You need to make your hard drive efficient by defragmenting the system on a regular basis. There are a few mobile phones and laptops which has a feature of modifying the CPU and also changing the cooling performance of the device, both these changes make a difference in the battery life and will increase it.
Brightness of Screen
All laptops and mobile phones have a brightness setting, and it is always best to keep the brightness at a low setting, this again will use up less battery and increase the battery life.
Managing external hardware
The more external devices you have attached to your laptop the more battery will be used up. Where possible it is best to avoid using external hardware with your laptop, such as charging your mobile phone, ipod, USB's etc.
Also when not in need turn of devices like Bluetooth, WiFi, 3G and GPS.
