Tip 1. Use Adobe Flash “on demand”
Tip 2. Set your Wifi sleep policy to never
This one sounds counter-productive, but trust us here. If you have access to Wifi throughout the day, and use it often, this will help save your battery. Use this tip with a Wifi toggle widget (see the homescreen section below) and it’s easy.
On your phone, tap the menu button and choose settings. From the list, choose Wireless & networks, then “Wi-Fi settings”. this is where you can choose what Wifi access point to connect to, but there’s also some options hidden. To see them just tap the menu button again and choose advanced. What we’re interested in is “Wi-Fi sleep policy”. Tap it, and set it to “Never”. What this does is keep your phone from switching to the 3G or 4G radio when the screen shuts off. Those radios need more power than the Wifi radio does, so any time we can keep Wifi alive we’re saving energy. Remember to put a shortcut or widget on your homescreen to quickly turn Wifi on and off for those times when you’re not around an access point. This will keep your phone from scanning for available networks.
