Why Does The Xiaomi Mi 6 Weigh So Much Compared to Other Flagships?

by Habeeb Onawole 6

One hundred and sixty-eight grams. That is the weight of the Xiaomi Mi 6. Doesn’t sound like its heavy for a phone, especially one with a 5.15-inch display. However, when you compare the weight of the Mi 6 to that of other flagship devices that share the same display size or even larger, then you would ask this same question. Why does the Mi 6 weigh so much?

Xiaomi Mi 6

The Xiaomi Mi 6 comes with a FHD display, dual rear cameras, 6GB of RAM, 64GB/128GB of storage and a 3350mAh battery. Its body is made from a mixture of glass and metal. Glass on the front and rear, and a metal frame that goes around it. But does that justify its 168g weight?

Below are a list of phones that weigh less than the Xiaomi Mi 6:

  • Samsung Galaxy S8 – 5.8-inch dual curved display, 3000mAh battery, aluminium frame with glass front and back  = 155g
  • Huawei P10 – 5.1-inch display, 3200mAh battery, aluminium unibody = 145g
  • LG G6 – 5.7-inch display, 3300mAh battery, aluminium frame with glass front and back = 163g
  • Moto G5 Plus – 5.2-inch display, 3000mAh battery, aluminium unibody = 155g
  • OnePlus 3T – 5.5-inch display, 3400mAh battery, aluminium unibody = 158g
  • Xiaomi Mi Note 2 – 5.7-inch display, 4070mAh battery, aluminium frame and glass front and back = 166g
  • Moto Z Force – 5.5-inch display, 3500mAh battery, aluminium frame and glass front and back = 163g
  • Xiaomi Mi 5 – 5.15-inch display, 3000mah battery, aluminium frame and glass front and back = 129g

Some of the devices above have more or less the same screen size as the Mi 6, others have larger displays. There are also others with larger displays and larger batteries but the unique feature they share is they weigh less than the Mi 6.

Take the Mi Note 2 for example. Battery capacity is 4070mAh and display size is 5.7-inches but it still weighs 2g less than the Mi 6. It is also built from metal and glass. We are trying to understand why the Mi 6 weighs more and the only reason that comes to mind is the aluminium frame being the culprit for the extra weight.

Do you have other reasons for why the Xiaomi Mi 6 weighs so much? Please, do drop a comment.

    r u serious?! obviously it’s the stainless steel frame. it doesn’t come with an aluminum frame. do your research before posting garbage unintelligible article.

  • I’m just guessing but it may be that it is made out of metal rather than glass. The internal components can’t be that different from what we are seeing in other flagships. I personally don’t like heavy phones, not that I can’t manage the extra weight, it is just that it is like large bezels. Excess bulk of any kind detracts from elegance in my view. Phones generally do appear to be getting heavier with each passing year however. I expect in a few years that the average weight of a 5.5 inch phone will be 200 grams unless some new lightweight strong material is discovered. Part of the problem is trying to cram more sophisticated hardware into phones while also needing to make them resistant to breaking when dropped.

    Stainless steel frame. The iPhone 4/4S had stainless steel frames too and they weighed 140g with their tiny 3.5mm screens.

    The Mi5 was exceptionally light considering the specs it had. Read a review out there about the Mi5, you’ll find that every single review mentions the weight of the phone, most are surprised by the light weight but some attributed it to poor build quality. There’s nothing hugely different about the Mi6 and current flagships just that its a little heavier, gives it a bit more of a premium feel and the idea that its packing some good specs with a strong body. Stop digging into it too much and a whole article wasn’t necessary. If you want to believe its because of the new metal body etc. then that’s up to you. The article already compared phones with metal body’s lighter than the Mi6, some of those phone have more metal than glass and are still lighter than the Mi6.

  • Worth noting that the new Sony Xperia ZX Premium with a 5.46 inch display weighs 190 grams so the Mi 5 is not the only heavyweight new phone. At this rate, most phones will be over 200 grams in the near future. Sony’s last phone of a similar size, the Z5 Premium was 180 grams so the trend in phone weight is clearly upward.
