It looks like the battery is draining after using Safari, even when plugged in to charge. I tried closing down the Safari app by double pressing home and swiping up but this did not fix it. Forced to power off in order to get the iPad to charge. Tried a few battery apps and it says the battery is healthy. Prefer to use Safari but for now using Dolphin until a solution emerges. Any tips? iPad Pro 9.7, wifi model, fully IOS updated.
