The Google Nexus 7 fares well with battery life in comparison with other smart phones and tablets, owing to its massive 4,325mAh battery and shortage of 3G connection. Still, if you are sapping its power stores by devouring HD videos at maximum screen brightness, you’ll welcome any extra juice you are able to wring out of this tasty tab.
The following guide runs through the entire sections inside the Settings application which you can tweak to eke much more life from your Nexus 7’s cell.
The power control widget
A long-standing member of the Android widget set, this permits you to control Wi-Fi, GPS, account synchronisation and screen brightness.
Wireless and networks
Network Notifications: in the event you switch this off, the Nexus 7 will stop actively looking for new networks.
Keep Wi-Fi on during sleep: the ‘only when plugged in’ option is the most effective compromise between power use and convenience
For the sake of security and battery life, keep Bluetooth turned off until you wish to have it. To further improve battery life, minimise the ‘Visibility timeout’ so the tablet will deactivate Bluetooth once possible.
Near field communication (NFC), the technology that comes into play if you are using a tool to tap to pay for goods in a store, as an example, can also be disabled. It uses so little power it probably isn’t worth turning if off though.
Airplane mode disables all wireless systems and should save lots of power, so long as your activities don’t require a web based connection.
If you’re pestered by various notification sounds, they are often quite distracting in addition to requiring power. Set the notification volume very low or to zero.
Touch and screen lock sounds
Again, these could be somewhat annoying and require energy — disable them.
The Android battery usage meter (Settings > Battery) usually shows that the screen is constantly the largest power drain. The Nexus 7 uses LCD, not AMOLED technology, so using dark-themed wallpapers and apps is not going to save power, because the backlight is often on. Regularly, automatic brightness manages things for you, but when you would like to save every last Watt of power, disable automatic brightness and decrease it to the minimum level.
Avoid using live wallpapers. They may consume RAM and CPU cycles, all of which use energy, in addition to the ability needed for driving the pixels at the screen.
Keep the time for the screen to fall asleep as short as possible — but not rather a lot that it spoils your delight in the device!
Battery and apps
View the battery chart to match how each app is hogging the flexibility. Under normal usage, the screen will always sap one of the most, but when you discover an app accounting for a huge percentage of your battery drain, it is advisable to consider uninstalling it or adjusting its settings.
GPS consumes power because it tries to maintain a lock on satellite signals. Unless you can use the Nexus 7 as a sat-nav, keep it turned off. If you’ll mostly be using your tablet indoors, always keep GPS switched off as it’s unlikely you’re going to get a signal anyway.
Avoid using all of the cores
The Nexus 7 runs on a quad-core Tegra 3 processor but keeps power consumption down via a low-power fifth core when performing tasks with low processor requirements. Therefore, to maintain power usage down, avoid processor-intensive apps. More often than not of thumb, if an app is making your tablet heat up, avoid using it. Heat is wasted energy out of your battery!
Battery care is regularly overlooked. The battery have to be initially conditioned with one or two discharge-to-zero cycles. Thereafter, frequently discharging lithium-ion batteries your entire thanks to zero damages them. Try and keep the battery topped up above 50 per cent, after which occasionally do a whole discharge cycle so the battery can recalibrate itself to supply more accurate readings.
Finally, in case you take the Nexus 7 out and about with you and cannot depend upon having a mains socket, put money into an external battery (which include Proporta’s TurboCharger 7000), to charge the Nexus 7. You may always continue to apply the tablet while charging.
