Restart the device

Smartphones are just like computers. They have Processes and Services running in the background and need a restart regularly (At least once a week). If these processes and services are running for a long time without a restart, they may cause issues.

Restarting your device gives it a fresh start and is sometimes all you need to fix your issue.

 

*Press and hold the Power button on your smartphone to Restart the device (If the restart isn’t available, turn Off and then turn On your smartphone).

 

If you want to know how long the device has been running, follow the steps below:

  • Open Settings
  • Scroll down and tap About Phone (If you don’t see this option, tap System and then proceed)
  • Tap Status
  • Scroll down and check Uptime (The time listed here is in hours. Anything above 168 hours needs to be restarted.)

Check Battery History and Educate Customer

  1. Pull down the notification panel and tap the settings icon.
  2. Scroll down and choose Battery.
  3. Tap the battery graph to view a details.
  4. Now, you should see the Battery History, a graphical representation of the battery discharge rate. Check the signal strength, awake and screen on time.
    Note: This resets every time the battery is charged to 100%.
  5. Example 1 (Poor Network Signal)
    • As signal strength decreases, the device requires additional power resulting in battery drain.
    • The cost of 1 hour’s worth of calls is 150mA, assuming a strong signal (Green). So, on a 2000mA battery, it takes 8% of total capacity (8% =150/2000).
    • This means the same 1 hour of calls could cost as much as 23% of battery life (23% = 450 / 2000)
    • If the customer’s home or office is at a location with poor network signal, the battery may last less than normal.
    • Compare the colour of the network in the image to the ‘signal strength vs. battery usage’ below.
  6. Example 2 (Wake Lock)
    • (Refer Example 2) If the “Awake” is more than “Screen ON”, then you might have installed an app which has a wake lock.
    • Wake lock is used by app-developers to control the power state of the device. It can be used to keep the processor running and sometimes prevent screen from dimming or going off.
    • Apps like Anti-virus and Battery savers come with wake locks, so that they can monitor the device without interruptions. We suggest not to have these apps as Android is a safe operating system and manages battery well by itself.
