Oppo R7s battery life

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.

Moving on to video playback and the R7s shows another splendid performance. Over 14 hours on our test reel means that the R7s is without competition. The only one that comes close here is the Moto X Play, if 12 hours is close. The Galaxy A7 performs adequately, and the OnePlus 2 and LG G3 show a passable result.

It’s worth noting though, that if movie-watching is your thing, Oppo’s own R7 Plus lasts a whopping 18 hours in our test and has a larger 6-inch screen, which lends itself even better to multimedia consumption.

Where things fall apart for the Oppo R7s is web browsing. Its 8 hours in our standardized test are only an average result and one that leaves us wanting, especially after the bar was set so high in other areas. If most of your screen on time is on the web, the Moto X Play will give the best longevity, at almost 12 hours.

The Galaxy A7 outlasts the R7s by an hour and a half, and the OnePlus 2 scores on par with Oppo’s 5.5-incher. The Xperia C4 is only good for 7 hours, while the G3 throws in the towel after a completely inadequate 6 and a half hours. Good thing, you can pop in a spare battery there.

To sum it all up, the Oppo R7s did very well in our battery test, with excellent longevity in voice calls and video playback. Web browsing endurance is nothing special though, and ruins the overall impression.

Make note that our proprietary score also includes a standby battery draw test, which is not featured in our test scorecard but is calculated in the total endurance rating.

The battery testing procedure is described in detail in case you're interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.
