I'm new to Appium and was designing a simple testcase to find an element and to click on a mobile element. I used real devices(Android) instead of emulators. It took about 2 mins or more to find the element and click on the element. As choosing Xpath to find elements in Android is a slower strategy, I used Accessibility Id but couldn't find any difference in the performance.
newstart_ele=driver.find_element(by=AppiumBy.ACCESSIBILITY_ID,value="NewstartButton")
newstart_ele.click()
