One of the better inventions for smartphones was push email. But you should be aware that this very handy feature comes with a significant drain to your device’s battery.
Every smartphone I know of supports push email, a system in which messages are “pushed” out to your phone as soon as they arrive on the remote mail server. It’s the opposite of pull email, in which you set your phone to check for messages on a regular schedule, or manually ask that they be delivered.
I generally have my devices configured to push both my work and my personal email to me, but I always try to keep aware how much this drains the battery.
With my current smartphone, I have recharge it every day, unless I turn push email off. When I do, it will go for much of a week on a single charge. This is with the device just sitting quietly waiting for me to use it. Naturally, if I’m on the phone a lot or using it to surf the Web, the battery life is much shorter.
A Vacation Tip
The next time you’re on vacation, be sure to turn push email off. For one thing you’re supposed to be relaxing and you can’t do that if you get notified every time you get an email from the office. But switching to manual email delivery will not just help your social life, it can also really save your battery life too.
I tend to forget to plug my phone in when I’m on the beach or some resort because I’m outside of my normal routine. If I have push email turned on, whenever I think about my phone it’s usually dead or close to it if I’ve left push email on. If I’ve switched to manual, it always has a full charge.
Just something to think about next time you’re on the road.
