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.

    Excellent review. But can I be the only one posting to spot that Apple are actually delivering two fundamentally different SEs aimed at two very different markets? In developed markets, and for upgraders (like me, in my case from a 16GB 4S because I saw nothing in the slightly androidy, blingy, mini-tablety 6s to justify the expense) the 64GB SE is a totally awesome product, is still I believe in short supply, and with the cost of the additional memory will keep Apples ASP healthy. For other markets there is the 16GB, partly reflecting the likely lower mobile bandwidth available in many developing markets: 16 will be enough there, but not for existing users.

    I'm extremely happy with mine: I now expect Apple to stick with the format very closely for several iterations as the mature one-handed smartphone phone, just doing some amazing technical stuff shrinking the increasing power of the over-size "flagships" to fit.

    This will most likely be my next phone, whenever I get tired of my note 4. I want system updates and a small phone again.

    I wouldn't mind a smaller phone (have an iPhone 6S+ at the moment) but I think this is too small. I think the has the ideal size screen - I just wish they would increase the battery life a little.

    Something I really wish tech reviews would cover: what is the _minimum_ brightness of the screen?

    As an example, my 2012 Nexus 7 is too damn bright at night.
    My Galaxy S5 is also a bit too bright, but because it's an OLED display, it can be dimmed further in software simply by drawing a translucent black layer over the screen. This

    Oops, I left a dangling word there. I was going to say: This is one major reason I prefer OLED displays.

    This is the perfect phone for first time users, remember that each year there is a new generation of kids looking for a smartphone. For families that are already in the Apple garden this is the go-to choice for your kids (if you need a new device). It's also going to be snapped up by companies looking to give their employees a basic device.

    There is no 128gb option for the iPhone SE.
  • TheinsanegamerN - Monday, May 16, 2016 - link

    I wish there was. or 256GB.
  • fire400 - Monday, May 16, 2016 - link

    i have the 64gb version, huge upgrade over 16gb..
    and if there was a 256gb version that cost +/~$800, I would probably would have seriously considered it...

    I think this is a very biased review. You have completely neglected the negative aspects of the phone.
    1)The phone has a 4 in display but such huge bezels. They could have easily included a more usable 4.5 in display if they had the technology to incorporate narrower bezels.
    2) The finger print sensor is painfully slow. Even a $300 android phone has a faster scanner.
    3) The front camera is terrible. Even a $200 android phone has a better front camera.
    4) What is the use of 4k recording when your display doesn't support it. Yes you can play it on an external device but that is besides the point.
    5)I am sure there are phones from last year that cost lesser that this device but are much better. For example Samsung Galaxy S6 which is better in every aspect except batter life.
