While OEMs strive hard to cram in more and more pieces of muscle “hardware” into your smartphone, battery life has become a really scarce commodity these days. With smartphone processors churning up HD videos and games, they drain the “juice” out of your still limited, lithium-ion battery. Let’s explore how, with few easy steps, you can conserve your battery.
1. Reduce your Screen Brightness
A major portion of your battery goes in backlight. Reducing the brightness saves a lot of battery.
2. Disable adapters when not in use.
3G, Wi-Fi, Bluetooth, NFC, GPS operate on separate dedicated adapters. Each of these use radio waves, and thus demand a large share of battery. Switch over to 2G when not doing heavy browsing. Turn off Wi-Fi, Bluetooth, NFC and GPS when required.
3. Use Wi-Fi Sleep Policy
If you use Wi-Fi exclusively for connectivity and wish to stay connected then enable the Wi-Fi Sleep Policy. This shuts down Wi-Fi temporarily when no data is being sent or received.
4. Use dark wallpapers
Displays, especially AMOLED screens, use less power to display black than brighter shades. Using dark wallpapers or better black or no wallpapers will help you to increase the battery life up to 10-20%. It is best to avoid Live Wallpapers, the interactivity, animations and the candid provided drain a lot of battery.
5. Disable background data traffic
Apps like GMail, Whatsapp, Facebook, Viber, Twitter, LinkedIn, Google Play, periodically check for updates and incoming messages all time, while in background. This increases the network uptime and thus drains battery. So it’s better to disable the data connection, unless you have a reason for remaining always at sync.
6. Prefer Wi-Fi to GPRS
Wi-Fi utilizes a radio controller with less power as the signal is usually sharp and clear. GPRS requires much power as the base station may be miles away. Moreover. a 3G/4G network demands yet another radio for voice data. Prefer Wi-Fi for data intensive operations like streaming, video calling, downloading or installing large apps, uploading files to cloud services etc.
7. Disable Auto-update in Google Play
The Google Play service checks for available updates of installed apps. This creates more data traffic and hence eats away the battery. So advisable to disable auto update. But if you prefer to be always up-to-date opt for “Update over Wi-Fi only”.
8. Prefer less widgets
The cleaner the desktop, less is the resource usage hence more battery life. Prefer using less widgets. A simple clock along with some quick shortcuts will do fine.
9. Prefer a good network
The phone puts in more energy in calls when there is a spotty signal. So it’s better to switch to a carrier which gives good network coverage in your area.
10. Turn OFF vibrations
Vibrations use more battery and it’s advisable to turn it off when not required.
11. Keep your device cool
High temperatures shorten the battery life. Batteries perform better in cool temperatures. So keep your device cool.
12. Do not overcharge
Normally the phone charges up in 2-3 hours. But if you leave it connected to the charger throughout the day, it lowers the life-time of the battery.
13. Set a rigid bedtime
Power off you phone each night. If not possible, turn-off all non-essential stuff overnight.
14. Turnoff animations and touch feedback
Switching off touch feedback, transitions and other animation effects will extend your battery life. These visual effects increase processor load resulting in battery drain. IMO, these are absolutely unnecessary, your eyes and hands are more than enough for knowing that you pressed a microbutton.
15. Always be updated
Newer versions usually are resource optimized than previous ones so generally are less resource hungry. Besides, each update brings in a casket of features!
Note that these tips apply to all devices in general. Be it an iPad, iPhone, Windows Phone, Symbian or BlackBerry. You need to do required settings and tweaks appropriate for your device.
