If you were unimpressed with the battery on the iPhone 6s when it was unveiled recently, you may want to think again.

Apple recently unveiled the iPhone 6s, and it's packed with lots of new features and beefier hardware specs than ever before.

All except for the battery, which Apple actually downsized from the iPhone 6 to a 1,715 mAh juice pack, in what seemed like a step backwards for the company -- and to much dismay for those who had dealt with previous iPhones' low battery life were hoping to finally have a long-lasting iPhone this year.

Well, according to Phone Arena, you can hold your disappointment. In their battery tests, Phone Arena found that the relatively tiny iPhone 6s battery unit not only stood up to competitors, but broke a record.

Running a proprietary benchmark test on the iPhone 6s designed to replicate typical power consumption representative of real-life usage, the smartphone news blog found that the iPhone 6s (despite its dinky battery size) lasted longer than every other major premium smartphone besides two: the hyper-efficient Sony Xperia Z3 compact and the Samsung Galaxy S6 Active.

Both have considerably larger batteries, with the Samsung Galaxy S6 Active being more than double the size of the iPhone 6s's pack.

In the tests, the iPhone 6s lasted 8 hours and 15 minutes, besting phones with larger juice packs such as the Samsung Galaxy S6 Edge, the Sony Xperia Z3+, and the HTC One M9. It also beat the larger-battery iPhone 6 by almost three hours.

On top of that, discounting battery size, the iPhone 6s actually broke the record for battery efficiency previously set by the Xperia Z3 Compact. To give you an idea of the difference, Phone Arena noted that if both had the same maximum-sized 3,500 mAh batteries, the Xperia Z3 Compact would have lasted about 13 hours and 30 minutes and the iPhone 6s would have gone for 16 hours and 50 minutes.
