Battery For Samsung Galaxy S7

Battery capacity is one more key area where Samsung gives you more with the Galaxy S7. The smartphone packs a 3,000mAh power bank, a substantial increase over the S6's 2,550mAh. Okay, the battery is still sealed, but that's a lot easier to live with when there's simply more of it.

It's also quick to charge, even if the S7 only supports Qualcomm's QuickCharge 2.0 standard and not the latest version 3.0. Samsung promises 0 to 100% in 90min for the S7, but doesn't say just how rapidly those percentages climb from flat to, say, 70% where it starts to taper off.

Much like the company's last-year flagships, the Galaxy S7 is also capable of wireless charging with pads compliant with both Qi and PMA. Samsung will also sell you a fast wireless charging pad, which can fill up the battery nearly as fast as a cable will.

Samsung Galaxy S7 review

Now, let's move on to our test results, where the S7 does indeed outlast its predecessor. 23 hours of voice calls on a 3G network is three more than the S6, and the nearly 15 hours of video playback are about 2 and a half on top of last year's model, and an impressive achievement in its own right.

It's web browsing that is a slight letdown, at nine and a half hours with the built-in TouchWiz browser. We did manage to squeeze close to an hour more using Chrome, but even 10:20h isn't spectacular. Still, in the scorecard we've used Samsung's own browser result, as that's our default course of action when more than one app is provided.

The Always On display feature was always going to be a battery drainer, no two ways about it. Samsung's claim that it would cost you 1% per hour seems about right and it does leave a huge impact on the overall endurance rating. That's because our proprietary score also includes a standby battery draw test, which we carried out with the AOD off and then once again with AOD on. These results are not featured in our test scorecard but are calculated in the total rating.

Since its launch, the AOD setting has been optimized and now allows you to schedule times to activate it. Of course, your mileage will vary depending on how long you keep the phone out of your pocket.
