Many of us have a tablet or an extra phone (or more) that we keep lying around the house or office for media use, for reading or browsing, for testing, or maybe even as remote controls for smart home appliances. Thing is, 8 times out of 10, when you pick up this tablet or phone to use it, you discover the battery is completely drained because you forgot to put it on the charger and you haven’t used it in a while so you didn’t notice the low battery level.

Or if you don’t even want the device to sync when it’s charging, then you can choose Never.

This setting is magical.
The main downside to choosing this setting is that you’ll probably get bombarded with
