Small phones with best battery life

Small phones with best battery life
If you are in the market for a small phone, your options are a bit limited: most phones these days tend to have larger screens, but also a bigger physical footprint so it's often a struggle to operate them with one hand or carry them in a pocket. But even if you've found a compact smartphone that you like, how good is its battery life?

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:

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

hours Higher is better
Apple iPhone XS
8h 37 min (Excellent)
Apple iPhone 8
8h 37 min (Excellent)
Apple iPhone 7
7h 46 min (Good)
Apple iPhone SE
7h 41 min (Good)
Samsung Galaxy S9
7h 23 min (Good)
Samsung Galaxy S8
8h 22 min (Excellent)
Google Pixel 3
8h 22 min (Excellent)
Google Pixel 2
8h 40 min (Excellent)
Sony Xperia XZ2 Compact
9h 13 min (Excellent)
Motorola Moto G6
8h 25 min (Excellent)
Honor 10
8h 44 min (Excellent)

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?

Battery life is almost as important as size to me. Both matter so thank you for this! It kind of makes me want to try the Xperia XZ2 Compact again...

Same here, I wish there were small phones with HD screens and two-day battery life, I would totally get such a phone.

I can confirm that. XZ1 Compact last forever. On average usage, only need to charge it twice a week.

It's just a tick bigger (.2") than the XZ2C but Sony's XA2 is a battery monster.

Literally none of the phones listed above are "small", save for the SE. Even the Xperia Compact is too big to be small.

How is XZ2 too big? It's smaller than every other 5" phone from years back, even smaller than a Samsung Galaxy S3 quite significantly.
