We set out to find out and we have picked the best compact phones around: from the iPhones to the Android ones, and we have measured their battery life under the same conditions, with equal brightness and equal other settings.
Which one came first?
Take a look at the chart below to find out:
There is one phone that clearly stands out with its incredible battery life and that is the Sony Xperia XZ2 Compact.
Great job, Sony!
And all of the Android phones in this ranking feature a Full HD resolution screens that are sharper than the screens on the iPhone 8, 7 and SE, so they are carrying a heavier load in terms of pure pixels. (The default resolution on Galaxies is Full HD, but they can go to the higher Quad HD resolution as well.)
Imagine if we had a small Android phone with a good HD display: Apple has showed us that it gets some tremendous battery life results with the iPhone XR and its display, despite the lower resolution, looks very good. So... maybe this year, Android phone makers? It's one easy way to climb to the top of the battery charts!
Interestingly, we recorded the worst battery life on one of the otherwise most powerful and well-equipped phones out there: the Galaxy S9. It was not terribly bad, but clearly behind the pack. We sincerely hope Samsung improves this in the Galaxy S10.
So... what is your favorite small phone?
And how important is battery life for you when you go to buy a new phone?
