Google Nexus 4
The Nexus 4 is powered by a 2100mAh battery

Google's Nexus 4 is powered by the same 2100mAh battery as the Samsung Galaxy S3 and the HTC One X+. However, the Internet search giant claims its phone offers 15 hours of talk time and 390 hours of standby time.

To test these claims, AnandTech pitted the Nexus 4 against a number of high-end rivals. The tests showed only moderate levels of performance, measured against phones including the iPhone 4S and iPhone 5, the Galaxy S3 and the One X+.

However, if you're interested in making the battery on your Nexus 4 last longer, check out these tips. IBTimes UK warns users these are not guaranteed to extend battery life and will not be held responsible for the consequences.        

  • Turn off extra functions like Wi-Fi, Bluetooth and GPS when not in use (to locate GPS settings, browse to Settings > Personal > Location Access)
  • Apps like navigation systems and maps are power-hungry, since they use the GPS function to provide information. Turn them off when not in use
  • Reduce screen brightness and set shorter sleep time-outs to save battery life (to do so, browse to Settings > Device > Display)
  • Disable automatic syncing for all apps unless absolutely necessary (to do so, browse to Settings > Personal > Account & Sync)
  • Note: Once this setting is so optimised, users will no longer receive notifications about software updates. They will have to be fetched manually 
  • When out of coverage area, switch to Airplane mode (to do so, press and hold Power until options dialog appears on screen and then select that mode)
  • To monitor battery charge levels and usage details, browse to Settings > Devices > Battery, where a list at the bottom provides information about each app and service in use. Tapping on each graph provides in-depth information. The settings within individual apps sometimes include options to adjust power consumption or you can choose to disable power-hungry apps completely
  • Avoid using Live Wallpapers (use wallpapers without animation) because they drain battery charge very quickly. Try and use darker colours   
  • In general, longer ringtones need more power. Therefore, try and chose shorter tones - either beeps or something similar. Also avoid vibrating alerts, unless necessary
