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?
Hello everyone, recently my tablet PC CWI538 needs to be recharged after using it for 1 hour, sometimes it is turned off without using it, and it can be used after turning it on, especially in winter, what is going on?
