How do you keep mobile devices in school charged all day? If your school uses BYOD, what do you do about keeping those devices charged? Has anyone using cell/mobile phones especially with students encountered battery power issues?
I remember classrooms with cords strung across the floor to keep the laptops charged after the batteries refused to hold charge more than an hour. That presented a safety issue for students who left their seats during the class period. It also meant reconfiguring desks to keep them close to wall outlets.
Has anyone used Juice Defender, a free mobile app for android phones that prolongs the battery life between charges? The app manages and monitors power consumption as well as data consumption and WiFi settings on your phone. To save power, the app will enable or disable settings to conserve power.
Please share how you are coping with battery power issues in your classroom and on your personal devices.
Michael Keller shared the following information about battery power in another discussion:
We have three EVOs in our household, and I've found the best source of Android info is http://www.sprintusers.com/forum/forumdisplay.php?f=145 This is the subforum for Android phones, and while it tends to be Sprint-oriented, there's LOTS of good info here. There are suggestions for programs like Watchdog which looks at your running apps to see what might be on and what might be eating your battery unnecessarily. There were a couple of positive comments about Juice Defender.
My experience is that the #1 thing that eats battery life is the screen. The more you have your screen lit up, the faster the battery goes.
Searching for a signal is #2. If you're in a weak signal area, the phone will use more battery as it hunts for the signal. Having no signal uses less battery than having one available and having it come on and off.
Hunting for WiFi is #3. I leave my WiFi on all the time, but what really kills the battery is when there's WiFi available but it can't connect. I figured out that I needed to tell the phone to "forget" that WiFi connection. Also if you have your apps set to auto-update, some update practically every day.
I've found having an extra charging cord to be the handiest app. That data consumption aspect in Juice Defender may be useful for people who are on limited data plans. (Sprint's Everything Data is unlimited.)
This is, will be, a concern for many districts. With the use of mobile devices in schools on the rise, one will need to consider how to keep them 'powered up'. Older schools have perhaps 4 power outlets in their classrooms,one on each wall. When you have a TV, projector, DVD player, document camera and so forth, all needing power, it can be tricky. Some media centers in my district had charging stations. Kids don’t always bring their power cord to school. Think about all the different types of cables and connectors and it isn’t feasible for a school to be able to provide all of that. One concern is keeping someone else’s device secure/safe. What effect will the increased use of power do to the energy budgets of schools?
