The Amazfit BIP features a more Apple Watch-esque design and comes with a 1.28-inch (176 x 176 pixels) always-on touchscreen. In addition to mirroring your phone’s notifications on your wrist, the watch can also log your runs, cycling sessions, and more. There’s an optical heart rate sensor as well and it’s IP68 rated dust as well as water resistant. However, the biggest highlight of the Amazfit BIP is the fact that it can last nearly a month on a single charge. There’s a low-power mode too which can extend that metric by fifteen days. There are four color options — Onyx Black, Cinnabar Red, White Cloud and Kokoda Green. The Amazfit Stratos, as clearly apparent from the price, is the more premium offering of the two. For starters, it has a clearer always-on touchscreen with a resolution of 320 X 300 pixels. In addition, the device is capable of tracking a lot more activities including swimming, skiing, Tennis matches, and more. One of the key reasons for that is the presence of a range of sensors like a Gyroscope which are not available on the more affordable Amazfit BIP. As far as the specifications are concerned, the Amazfit Stratos has 512MB of RAM, 4GB of onboard storage, and a dual-core chipset clocked at 1.2GHz. The design is also made out of more expensive materials such as ceramic bezel, stainless steel buttons, and the glass fiber casing. It has a water resistance rating of 5 ATM and a 290mAh battery which can last five days. The heart rate scanner on the Stratos can also evaluate your VO2max fitness level. It will available in only one Black color. Both the smartwatches are compatible with iOS and Android and will available exclusively on Flipkart.
