It’s never a surprise, but it’s always a disappointment. Your phone battery is DEAD!

How could this happen? You did everything right, including using Wi-Fi at work and reducing the screen brightness. It doesn’t make sense.

Are you ready for the major rub? 60 percent of battery drain happens when your phone is NOT in use. There’s no single reason to explain the battery drain, but email is a major contributor. There are two words you need to know when it comes to email – push and poll. Here’s a brief description:

  • “Push” mode: Your phone will “connect” each time an email comes in. If you get 75 emails in a day, your phone will connect 75 times. Each time it drains your battery a little.  

  • Poll: Your phone will “connect” and receive emails at preset intervals (probably every 15 minutes). If you get 75 emails, your phone will connect only five times.  

So, what does this all mean? Every time your phone “connects” to receive email, it drains your battery.

Which setting is better? There’s no single right answer. If you get a lot of email, let’s say on a workday, “push” mode will drain your battery much faster. On the other hand, if you get very few emails, like on the weekend or late at night, “poll” mode will drain your battery faster than “push”. Your device will connect over and over, looking for emails that are not there.

The best compromise is a push/poll schedule. This will allow you to switch back and forth from “push” and “poll” based on peak email hours. You can tweak this on many devices under the “settings” menu.
