    That sounds like the battery is failing.

    If the battery voltage starts to drop under load, the CPU is slowed down to limit how much power it needs, rather than it crashing completely.

    Have a new battery fitted and it should be back to normal!

      It’s always on maximum brightness if that’s an issue too
