The Oppo R7s was at the office for a while, and in case you missed it on the homepage, make sure you read the review - it's a very attractive midranger. In this piece, however, we'll focus on its battery life and not looks and other merits. The smartphone comes with a 3,070mAh battery inside a body merely 7mm thick. We appreciate that the push for a sleek body hasn't meant a sacrifice in capacity, and the powerpack is quite generous for a 5.5-inch device. It's non removable, though. The R7s sits right in the middle of the R7 lineup in terms of display diagonal, and its battery capacity reflects that. We won't bore you with the numbers (which you can easily calculate for yourselves, if you're into that), but the R7s actually has more mAh per square millimeter than the R7, though not as much as the R7 Plus. Competing smartphones typically come with less juice. The Samsung Galaxy A7 packs a 2,600mAh cell, as does the Xperia C4. There are exceptions like the Motorola Moto X Play, which has an ample 3,630mAh battery, and next year's Galaxy A7 (2016) will see an increase in capacity to 3,300. Meanwhile the LG G3 packs a 3,000mAh battery, removable too. In the case of the Oppo R7s it's also worth mentioning that it supports the company's proprietary VOOC fast charging tech. Part of the retail package, the fast charger and special USB cable work together to deliver up to 4A of current at 5V to the smartphone. VOOC charger and cable in the retail box The battery inside is actually comprised of two separate cells, which can be charged simultaneously, thus reducing the current to each cell and keeping temperature in check. It also means that to make use of the VOOC fast charging you need both the charger and the cable to be compatible, because they have additional pins, missing in your garden variety pieces. You can certainly use standard chargers and cables as well, but at the expense of speed. The actual battery life of the Oppo R7s ranges from great to average, depending on what you'd be using it for. Voice call endurance is among the excellent bits. With just over 24 hours on a 3G call, the R7s can literally last you a whole day of constant talking (though please don't test it). Come to think of it, the Galaxy A7 tops it by an hour, the LG G3 by an hour and a half, and the Moto X is good for 26 and a half hours, while a OnePlus 2 can even crosses the 30-hour mark. That said, those are all excellent results, and the R7s' is one too. The Xperia C4 calls it quits in 13 hours, for an example.
