Battery Life

Our battery life tests have also been upgraded for 2016. Our web browsing test was previously shown in the first part of the Galaxy S7 review, and since that time it has been tweaked to the point that we're happy with the workload it puts on devices. We've also migrated to GFXBench's Manhattan test for examining battery life with a heavy GPU workload.

Web Browsing Battery Battery Life 2016 (WiFi)

In our WiFi web browsing test the iPhone SE does quite well. When Apple originally advertised that the SE has better web browsing battery life than the 6s and 6s Plus I saw some confusion from many people, but it's actually not a surprising outcome. The SE is using a much smaller and lower resolution LCD display than the other iPhones, which significantly reduces the total platform power. The boost in battery capacity from the iPhone 5s helps as well. Apple advertises that the SE can last two hours longer on WiFi than the 6s, and in our test it almost meets that target. 

Due to a recent move, I'm still trying to find a place with sufficient signal strength that I can use for LTE battery life testing. Until such a time, I'm unable to post LTE battery life results for the SE. In general you can expect LTE battery life to be a couple hours shorter than on WiFi, and Apple advertises that the SE can last three hours longer on LTE than the 6s, so if they get anywhere close to that then LTE battery life should be quite good.

GFXBench Manhattan 3.1 / Metal Battery Life

GFXBench Manhattan 3.1 / Metal Final Frame Rate

The 4-inch iPhones have never lasted long in GFXBench's battery test. With the new Manhattan test the GPU is doing a lot more work than it was with T-Rex HD, and there aren't any periods of idle. The iPhone SE achieves the lowest battery lifetime of just 1.46 hours. However, the on screen frame rate during the test is hitting Vsync, which is actually concerning because we moved to Manhattan to avoid the problem of devices hitting that cap and then idling in the middle of the test. As I've said in the past, you need to consider both performance and battery life in this test. The iPhone SE is obviously an improvement over the 5s even though it dies half an hour earlier, because by the end of the test the iPhone SE is giving you 6x the performance of the 5s due to the A7 SoC's greater degree of thermal throttling.

Charge Time

Like the iPhone 6s and 6s Plus, the iPhone SE ships with Apple's 5W charging block. While this can be quite problematic on a large phone like the iPhone 6s Plus, on a small phone it won't pose as much of an issue as the phone's battery capacity is much lower. Ideally we'd like to see a time to charge that is under three hours, and coming in under two hours is even better.

Charge Time

The iPhone SE charges quite quickly. We've seen improvements to charge time on the iPhone since the era of the iPhone 5s, and with the SE having a smaller battery than the iPhone 6s it makes sense that the charge time would be shorter. I do wonder how long it would take to get to full charge if Apple bundled a 10-15W charger with the phone, although with the current time being under two hours you also need to consider if the potential reduction in battery longevity from quicker charging is worth it.

    Once this thing goes on a sale it might actually be the first iPhone I buy with my own money to replace my Moto E (2015) as my second phone. Reply

    Sales on apple products are rare, and when they happen, the discounts are very small. Reply

    I'm well aware of that. But here in the EU (where the Apple prices are higher in general) the discounts also tend to be greater if they happen. Reply

    Best Buy was selling MacBook Pro laptops with a $300 discount about three weeks ago. Granted this was probably to clear inventory in preparation for the 2016 models. That's probably the best time to go Apple shopping. Reply

    "Sales on apple products are rare, and when they happen, the discounts are very small."
    I just bought my partner a iPhone6S on a contract in the UK where the phone effectively cost £250.
    On a side note, as an Android user, I found it very disappointing, there is lag at some points, its ability to hold a signal in my house is poor and it really is no more exciting than the 5S it replaced. And it is full of Apple bloatware that you can't uninstall or remove from the home screens.

    Eeeehn, it's a bit of a stretch to call it 'bloatware'. It doesn't take up much space, except in screen real estate, and most of it is actually legitimately useful if you haven't downloaded any apps yet. It does suck that you can't hide the ones that you don't want, though. Reply

    "there’s absolutely no reason to arbitrarily redesign a product every cycle"

    Thank you for saying this!

    There's absolutely no reason to release a new phone every year either. Reply

    Except to make money...add new features, cater to a different crowd, prevent product lines from going stale...I could go on, but there's absolutely no reason to continue explaining... Reply

    Earn money yes. The rest is nonsense. But it's cute that you bought into the marketing. Reply
