On paper, the Samsung Galaxy S9 and Galaxy S9+ come with batteries that are bigger than the iPhone X’s 2716mAh battery. The Galaxy S9 comes with a battery that is just a wee bit bigger at 3000mAh, while the S9+ comes with a substantially bigger 3500mAh battery.
Theoretically, this should mean that the Galaxy S9 and S9+ should offer better battery life than the iPhone X. But thanks to Apple’s strong integration between hardware and software, the iPhone X manages to offer better battery life than Samsung’s latest offerings.
In PhoneArena’s battery life test, the Galaxy S9 and S9+ last for 7 hours and 23 mins and 8 hours 5 minutes, respectively. In comparison, the iPhone X performs better than both these handsets and lasts for 8 hours and 41 minutes. Adding insult to injury, even the iPhone 8 with its paltry 1821mAh manages to outlast Samsung’s latest flagship handsets. The iPhone 8 Plus performs the best of the lot and lasted for 10 hours and 35 minutes in the test.
Samsung’s handsets make up for their poor battery life with their quick charging times though. The Galaxy S9 and S9+ take only 105-107 minutes to charge from 0-100 percent. The iPhone X, in comparison, took a staggering 189 minutes, with the iPhone 8 and iPhone 8 Plus taking 178 minutes and 148 minutes, respectively.
This means that you can easily charge your Galaxy S9 1.5x times in the time it takes the iPhone X to charge from 0 to 100 percent. Do remember that the stock charger was used with the iPhone X. You can greatly reduce the charging time of the handset by using a USB-PD charger which should reduce the charging times of the handset to a more reasonable level.
Apple has always been known for extracting the very maximum in terms of battery life from its handsets. In comparison, Android devices have always had to make use of humongous batteries to make up for the inefficient integration between their hardware and software.[Via PhoneArena]
