You can find information about the Samsung Galaxy tablet’s battery status in the upper-right corner of the screen, next to the current time in the status area. The icons used to display battery status are shown here.
You might also see an icon for a dead battery.
Heed those low-battery warnings! The Galaxy tablet alerts you when the battery level gets low, at about 15 percent capacity.
Another warning shows up when the battery level gets seriously low, below 5 percent — but why wait for that? Take action at the 15 percent warning.
When the battery level is too low, the Galaxy tablet shuts itself off.
The best way to deal with low battery power is to connect the tablet to a power source: Either plug it into a wall socket or connect it to a computer by using a USB cable. The tablet begins charging itself immediately; plus, you can use the device while it’s charging.
You don’t have to fully charge the tablet to use it. When you have only 20 minutes to charge and you get only a 70 percent battery level, that’s great. Well, it’s not great, but it’s far better than a lower battery level.
Battery percentage values are best-guess estimates. The typical Galaxy tablet has a hearty battery that can last for hours. But when the battery meter gets low, the battery drains faster. So, if you get 8 hours of use from the tablet and the battery meter shows 20 percent left, those numbers don’t imply that 20 percent equals 2 more hours of use.
In practice, the amount of time you have left is much less than that. As a rule, when the battery percentage value gets low, the battery appears to drain faster.
