More battery life results are in for the Apple iPhone XS and iPhone XS Max, and they too found that neither keep up with some leading Android phones.

Tom’s Guide put nine smartphones through the same test, which has the phones constantly roaming the internet on 4G at 150 nits of screen brightness. The iPhone XS lasted 9 hours 41 minutes, while the iPhone XS Max stayed alive a little longer at 10h 38m.
