hey guys this is austin. reports have comeout that some versions of the iphone 6s have up to 20 percent less battery life but isthere actually any difference? it all comes down to the chips inside. unlike previousiphones the 6s can have two different processors. chipworks took a closer look and found somethinginteresting: they’re physically different sizes. if you opened up an iphone 6s you wouldfind one of two chips, one built by samsung
aapl performance, that measures in at 96 millimeters squaredand another built by tsmc that comes in at 104.5 millimeters squared. the differencecomes because they’re built on two different processes, the samsung is 14 nanometers wherethe tsmc chip is 16 nanometers. all of this nerd talk aside, what this means is that notall iphone 6s’s are created equal. to find
out which phone you have go to the app storeand download the lirum info app. it’s free and is usually used for monitoring but whatwe want to find out is the model number. the iphone 6s with a samsung a9 is n71ap wherethe tsmc version is n71map. the same holds true for the iphone 6s plus, the samsung modelnumber is n66ap and tsmc is n66map. supposedly the tsmc model is the better version but iwanted to put that to the test. to find out i took a pair of identical iphone 6s’s,one with the samsung processor and one with the tsmc chip. i calibrated both screens to200 nits of brightness and ran the geekbench 3 battery test until each phone hit 50 percentbattery. the results were really surprising, the tsmc phone lasted a full fifty minuteslonger than the samsung model resulting in
a nearly 1.5 times difference in battery life.this was also noticeable in the temperatures of the phones, the tsmc iphone runs significantlycooler than the samsung phone under load. since geekbench is the absolute worst caseof how battery holds up under intense load next i ran a much lighter video test. i loadedthe same hour long youtube video with both phones connected to the same wi-fi networkand here there was a much smaller difference with the samsung phone using 15 percent batterycompared to 14 percent with the tsmc model. the end result is very interesting. for normaluse there’s a fairly minor difference but the tsmc iphone can give you significantlybetter battery life for heavy use. there’s really no way of telling which phone you’regoing to get before buying, the lirum app
is great but it only tells you after you’vebought the phone. my friend jon from tld also tested to see the difference in real worldbattery life and performance which you guys should definitely go check out. so what doyou guys think about chipgate? a big deal or no problem at all? let me know in the commentsbelow and if you enjoyed this video and want to see more definitely be sure to subscribeto the channel.
