sudden battery discharge

Continuing the discussion from Hi9 Pro - Battery sudden discharge?:

i have the same problem with Hi 9 tablet … was there ever a response from chuwi?

I never had any response from Chuwi - a pity, because this is an excellent tablet and I use it all the time. The charge stays good for around 16 hours, gets down to 30%, then within 10 minutes, it drops to less than 20% and rapidly goes down to low charge warning, with just Opera browser open.
I think you just have to keep your eye on the charge and keep a power bank handy.
Best regards,
