Most smartphones have large displays and touchscreens, reducing battery-life. Here is how you can get the most out your smartphones battery:
1-keep the display brightness at around 50 per cent, as it drains the most power;
2- turn off 3G, Wi-Fi, Bluetooth when not in use. Most phones have a dual-mode option which lets you switch between 3G and 2G networks automatically. For best performance, set this as GSM only;
3- avoid using the speakerphone: use the earpiece or earphones.
You can also carry a spare battery in case you are travelling and cant charge your phone regularly.
