I got a request to check this out from expats living in China. Here the short little video. Basically the native google translate on xiaomi works really really fast. Huawei is a bit slow. I think it might be due to trying to connect to chinese servers which way slower from Europe than from China.
Microsoft Translator seems to be the quickest on both.
