Tablets are becoming a popular mobile device, and their impressive endurance is one of the greatest draws. Most tablets can last eight to ten hours even when displaying mobile video or surfing the web.
This is plenty for most users, but there may come a time when you need even more life. These five tips can help you extract every second from your tablet’s battery.
Reduce Display Brightness
Most tablets are simply hardware strapped to a display, resulting in the characteristic tablet appearance. This provides a large display with minimal weight, but it also means there is a large viewing area to power. As with large smartphones, the display often draws more power than any other component.
As such, simply dimming the display will have a positive impact on battery life. While there’s often an automatic brightness feature available, it’s usually less aggressive than needed to provide maximum battery life. Taking control of brightness yourself is often a better option.
Turn Off Wireless Radios
Tablets do not rely on mobile data quite as much as smartphones, but they still make heavy use of it. Wi-Fi is standard on virtually all tablets, and many also include access to 3G and/or 4G from a major mobile data carrier.
These radios suck power, however. A 3G/4G radio can have a negative impact on endurance if used often or if used in areas with a poor signal. The solution is to just turn the radio off.
Obviously, disabling 3G/4G will cut of mobile data access unless Wi-Fi is available, but this is a trade-off that will sometimes be worthwhile. Turning of Wi-Fi as well as Bluetooth can further improve life, but the impact won’t be as drastic as turning of 3G/4G. Wi-Fi and Bluetooth radios are built to communicate over shorter ranges and consume less power as a result.
