[Android Central Question]

I've just got new tablet its a huawei t3 10 first when i got it other day out of box i charged it fully with usb charger supplied then used it till battery died then this morning put it ok charge but it never charged fully it was on 76% why won't it fully charge

Leave it on the charger overnight. If it's still 76%, you just got it, so have them replace it for a factory defect.

And in the future, start recharging at 40%. Dropping the battery down to 0% a few dozen times will kill it to the point that you'll have to replace it. (And if you do that every day, it could die in as short a time as a month.)
