In the previous post, I had walked you through various types of exciting Android games and I believe you had also witnessed how powerful Nexus S processor performed in the video. One of the readers had left a comment asking me about the battery life of Nexus S. Therefore, today I will be sharing some useful battery saving tips here to help you conserve more battery power.
Although the battery manufacturer claims that the Nexus S phone allows you to talk for almost 7 hours (using 3G network), but in real life it’s quite impossible to gauge based on just that. We all use our mobile device differently. Besides, some of you may love multitasking and that could affect the battery life too! Actually with just a few phone settings, you can easily conserve ‘Extra’ battery life so Nexus S could last longer.
First of all, bear in mind that if you want to ensure the maximum of your battery life: Avoid charging batteries for more than a week, as overcharging may shorten battery life. Secondly, always monitor your usage so to know which programs or apps are consuming most of your battery power. Luckily, Nexus S provides an informative screen on battery use info which can be found here:
Choose settings –> About Phone –> Battery Use
The information clearly outlines which applications are consuming the most battery power and if possible, reduce the usage of those apps as much as possible. I had personally tried out all the methods below and they did help! I was managed to extend the original 6 hours of playing Android games (without customization) to almost 12 hours (after customization)!
1) Always Put the Phone in Snooze Mode
Snooze the phone manually
Whenever you are not using the phone, press briefly at the power button to turn off phone display. Even the phone is snoozing, it is still pretty much alive and you can still receive calls or incoming messages.
Snooze the phone automatically
Google Nexus S has a built-in screen timeout feature which will automatically turn off the screen after a period of inactivity. You can control the timeout setting and set the value in between 15 seconds to 30 minutes. It’s advisable to keep the value at 1 minute or less (if possible) to save more battery power.
How to: Go to Settings –> Display –> Screen timeout –> Select timeout value (15 seconds, 30 seconds, 1 minute, 2 minutes, 10 minutes, 30 minutes)
2) Manage Power Usage From Power Control Widget
Thanks to the default Power Control Widget pre-installed on Google Nexus S. I can easily manage all important power usage right from the home screen as shown in the screenshot. Don’t underestimate these controls, if you turn off the unused app this will greatly help in conserving your battery power.
i) Set the screen brightness to minimum level
Even with the lowest screen brightness setting, the screen display will still be visible if you are using Nexus S indoor. The device may set the brightness to ‘auto’ by default so you need to check it yourself. Reduce the brightness whenever necessary contributes much in power-saving.
How to: Set screen brightness using Power Control widget available on homepage. Just touch the brightness button to change screen brightness. Otherwise, go to settings –> Display –> Brightness
ii) Turn off Wi-Fi, Bluetooth and GPS (Global Positioning System) will conserve more battery power as they require extra power to run wireless connectivity. Therefore, disconnect them as soon as you are out of the WiFi zone.
iii) Turn off Automatic Syncing and background data to save battery life as the phone will stop syncing and updating data (send and receive) in the background automatically.
You can touch Auto-Sync button to disable Automatic Syncing or go to Settings –> Accounts & Sync –> uncheck both Background Data and Auto-sync
iv) Turn off NFC (Near Field Communication) as it’s still a new technology and not widely use by people. Go to settings –>Wireless & networks –> Uncheck NFC
3) Turn off Phone’s Vibration
Disabling vibration option will also save battery life. Follow these steps to turn off the vibration option.
How to: Settings –> Sound –> Vibrate –> Never
You can also uncheck Haptic Feedback option to stop the phone to vibrate when you press the soft buttons and on certain UI interactions.
4) Make sure Your Phone System is Updated
Normally, latest system updates will fix some error bugs, hence improve battery life and performances. Therefore, always keep your current phone system updated. You can check the system update info as below:
Settings –> About Phone –> System Updates
5) Reduce 3G Usage
For your info, 3G network provides faster network and therefore, it consumes more battery power comparing to other slower network such as 2G or EDGE. Switch to 2G to save battery:
How to: Settings –> Wireless & Networks –> Mobile Networks –> check the option Use Only 2G Networks.
6) Use Static Image instead of Live Wallpaper
I know live wallpapers are beautiful and interactive but it will not help you to conserve battery power. So whenever you are in need of saving extra power, make sure to switch to static wallpaper. Just tap anywhere on your home screen for a few seconds and the below menu will appear for your wallpaper options:
7) Disable unused Phone and App Services
There are some phone and app services running at the background and they are actually slowing down your device. You can install a free Android app from Android Market called Advanced Task Killer Program to halt programs that run in the background or no longer in use. This will not only free up your memory resources, but also improves the battery power.
Extra : How to turn off all wireless & cellular connection in one go?
Activate AirPlane Mode will disable all wireless connections and data network at once. But be careful with this option because it will not allow you to have incoming or outgoing calls/messages too.
How to: Press and hold the power button, then choose Airplane Mode.
