Ask HN: Battery capacity of Asus Zenfone 3 Zoom vs. top tier smarthpones
So recently I was made aware of the Asus Zenfone 3 Zoom. Here&#x27;s a terse comparison of this phone to two of the currently top tier phones: (the reason I chose Plus and XL versions was due to the fact that their dimensions are comparable to those of Zenfone)<p>Asus Zenfone 3 Zoom [0]<p>--------------------------------------------<p>Battery: 5000mAh<p>Dimensions: 6.07 x 3.03 x 0.31 in<p>Weight: 170 grams<p>Screen: 5.5&quot;<p>Price: $329.99 [3]<p>Apple iPhone 7 Plus [1]<p>----------------------------------------------<p>Battery: 2900 mAh<p>Dimensions: 6.23 x 3.07 x 0.29 in<p>Weight: 188 grams<p>Screen: 5.5&quot;<p>Price: $969.99 [5]<p>Google Pixel XL [2]<p>----------------------------------------------<p>Battery: 3450 mAh<p>Dimensions: 6.0 x 2.9 x 0.2 ~ 0.3 in<p>Weight: 168 grams<p>Screen: 5.5&quot;<p>Price: $849 [4]<p>So through this overview, the phones are relatively the same size, weight, screen size, and yet the top tier smartphones&#x27; battery capacity is greatly behind that of the Zenfone. Why is this the case? I understand that the three phones may vary in camera, processor, build quality etc hence justifying the price difference a bit. But I have trouble understanding as to why do the top tier phones not focus on increasing the battery capacity, which clearly can be done as demonstrated by Asus. I would gladly be willing to compromise on some of the Pixel&#x2F;iPhone parts&#x2F;features for a greater battery capacity.<p>[0] https:&#x2F;&#x2F;www.asus.com&#x2F;us&#x2F;Phone&#x2F;ZenFone-3-Zoom-ZE553KL&#x2F;Tech-Specs&#x2F;<p>[1] http:&#x2F;&#x2F;www.gsmarena.com&#x2F;compare.php3?idPhone1=8064&amp;idPhone2=8065<p>[2] https:&#x2F;&#x2F;madeby.google.com&#x2F;phone&#x2F;specs&#x2F;<p>[3] http:&#x2F;&#x2F;www.bestbuy.com&#x2F;site&#x2F;asus-zenfone-3-zoom-4g-lte-with-32gb-memory-cell-phone-unlocked-navy-black&#x2F;5833504.p?skuId=5833504<p>[4] http:&#x2F;&#x2F;www.bestbuy.com&#x2F;site&#x2F;google-pixel-xl-4g-lte-with-32gb-memory-cell-phone-very-silver-verizon&#x2F;5656048.p?skuId=5656048<p>[5] http:&#x2F;&#x2F;www.bestbuy.com&#x2F;site&#x2F;apple-iphone-7-plus-128gb-black-verizon&#x2F;5581629.p?skuId=5581629<p>EDIT: Fixed spacing
