iPhone 6s Performance/Battery Tests: TSMC vs Samsung A9 [VIDEO]


Apple’s decision to use two different A9 CPUs for the iPhone 6s and iPhone 6s Plus appears to have created the mandatory controversy the media expects around the company’s smartphone launches (think: antenna-gate; bend-gate, etc).

Yesterday we shared how you can determine which A9 CPU is inside your iPhone 6s, and now YouTube channel TLD Today has performed unscientific casual tests to see if there are any performance differences between the TSMC and Samsung A9 CPUs in real-world usage.

Channel founder Jonathan Morrison had five iPhone 6s models on hand, with two of them being the ‘dreaded’ Samsung version. He put both versions of the phone through a time-lapse video test, 4K video recording test, an export of the 4K clip in iMovie (the Samsung chip was 4 seconds faster), Geekbench and GFXBench Metal (both had 39.9fps).

But in the end, the TSMC iPhone 6s had 7% more battery life compared to the Samsung iPhone 6s. So one could conclude again the TSMC version has slightly better battery life as we have read about so far.

Check out the video below:

YouTuber Austin Evans does a good job explaining the differences between the TSMC and Samsung A9 CPUs and also conducted his own tests between both chips. He similarly concludes the TSMC version brings better battery life under heavy use:

Is the slight difference in battery life between the TSMC and Samsung A9 a deal breaker for you?

    Having a TSMC 6S, I like what I see so far. As for the TSMC vs Samsung chip controversy, my experience has been Samsung, while adequate, lags in certain performances every time.

    It would be a deal breaker for me for sure, especially with TSMC having 7-10% better on battery life when iPhone already does not have a stellar battery life to begin with.

    Luckly mine is the TSMC one, otherwise I will return it.

    Where did you purchase it & which clout did you choose? It seems in a couple of people’s posts their white version (gold, rose or silver seem to have the TSMC chip more often.

    I ordered online from Apple directly. 1st day order.

    Thanks for replying!????????

    You still want the 12 nm over the 14 nm

    Do you turn off System Services you don’t normally use or need? It really makes a big difference. I’ve been using iPhones for a long time, and turning them off is one of the first things I do every time I get a new one. I only have 3 on (Cell Network Search, Find My iPhone, Location-Based Alerts). I unplug my phone everyday around 7:30am until 12:30pm (17 hours), and I use the phone usually for about 6 hours (making lots of calls, text, browse, the normal stuff), and will usually have about 25% left. Currently using iPhone 6, and it’s been the same after 1 year, and always on the most current iOS version.

    I’ve read many people complaining about iPhone’s battery life, but I honestly have never even came to close having an issue with it, regardless of which iPhone I was using. But that’s just me.
