To pick the first Google result that isn’t the manufacturer’s pages, GSM Arena tested the Oppo at 15:45 hrs battery life and the iPhone at 19:20 hrs.
I strongly expect to find the usual camera result from the last twenty years of “marketing megapixels” not translating into image quality, but that’s more subjective.
Doubtless you’re going to say that the Oppo is a bigger screen but then why did you choose to crow about 430mAh more battery capacity and not compare with the iPhone Duo?
