This is an idea for an app that keeps track of the battery levels across all your devices.
You probably have:
- A smart phone (e.g. iPhone, Android or BlackBerry). Battery lasts between one or two days typically.
- A tablet (e.g. iPad, Nexus 7). Battery last a few days, less than a week.
- A laptop. Battery lasts hours, but most of the time it is used with a cord.
- A Bluetooth mouse or track pad in the computer.
- A Bluetooth wireless headset. E.g. for running or just calling with it.
Perhaps also a second phone, a Kindle, a work laptop, …
How can you keep track of which device needs recharge when? How can you avoid taking your phone for commuting to find out is nearly dead?
The Solution Wouldn´t it be nice if you had an app that lists the battery levels of all your online devices?
It would also help you keep track of battery health, quick check before a long trip or just getting an alert at night to re-charge so you can use it for your commute next day.
Basically the app would request the battery level every so often. To save battery, you can make it to do it at most one quarter of the minimum recorded lifetime of each device´s battery.
Once recorded the app sends the timestamp and battery level to the server, or schedules to send it once you get online.
The app queries the server every so often to retrieve the lists of devices and their battery levels.
You can make the extra mile and calculate the remaining battery life both in idle and maximum use scenarios (you can get those statistical estimates after a few charge loads or with a few users with the same device and battery health status).
You can also tie it to your calendar and alert the user before a long trip.
It would also be very interesting to see aggregated data on battery performance.
You can monetize selling the app. I would pay for it.
You can also show ads, or even trigger ads for new batteries or servicing options once the battery health for a particular device gets too low.comments powered by Disqus
