Here are some important tips to extend your battery life on your android phone or device.  Below is my screenshot on the Galaxy S4, I normally go 2 to 3 days without charging. save battery life android galaxy s4 htc one xperia  

  1. Disable data or check mark “Use 2g Data” to save battery life, when you don’t need high speed data.  High speed data such as LTE, eats more battery life because it requires more power to pull data at fast speeds.
  2. Disable autosync of apps that constantly check for updates such as GMAIL, you can manually check for new emails when you desire.
  3. Use an app like Quadcore manager to safely turn off 1 or 2 of your core processors (depending on how many total core processors you have).  This will enable you to prolong battery life.
  4. Use an app like Greenify, to hybernate apps that keep running in background after you exit out of them. Greenify
