That battery usage times have a 10X range. I can show laptops and tablet reviews that test the time on battery and they can range from minutes to hours.

But if you factory reset the PC and it's not turning in times like it used to, then it may need a new battery since these are only rated for about 300 cycles which would be easy to wear out a battery every year.

HOW OLD IS THE BATTERY?

The tablet has been in use for 3 years. Usually I am fully charged. When I use it the next day, there is no power. I just shut it down. When I turn on the battery, the power is 85%. I do n’t know what it ’s like. It ’s always like this.

At three years.

That's old enough to have lost capacity. The test remains to be done about the factory reset and see how much time it gets. Bear in mind that NO APPS ARE INTRODUCED DURING THE TEST. GO NATIVE.

If that results in low times, time for a new battery.

Remember I take it you know how long the battery lasted when the tablet was new and are not hoping for more than that.

Thank you for your kind help. I will try it out. If not, I will only buy a new one online.
