EDITORIAL: Oppo's OnePlus skipped 14 to bring us an iterative upgrade of excellent OnePlus 13. The 15 is a very competent and affordable flagship with excellent build and performance, amazing endurance and fast charging, good screen and reliable camera setup. It adds AF selfie and replaces the excellent 3-step alert slider with an AI button. Also gone is the Hasselblad collaboration and branding, in fact: all cameras have been downgraded. Is it possible that Oppo reserves top performance for it's Find series? Find 9 Pro and OnePlus 15 share very similar design...

PROs
improved design and build, great SD 8 Elite Gen 5 with UFS 4.1 performance. proper 48hr endurance from a 7300mAh Si-C battery with sub-50min 120W (50W wireless) charging. >1300nits bright 450ppi LTPO AMOLED screen with Dolby Vision, IP69 protection (down to 2m for 30min). reliable imaging from 50MP 24mm OIS main + 50MP 80mm OIS periscope telephoto + 50MP 16mm ultrawide (all with PDAF). good 32MP 21mm AF selfie. up to 4 years of updates of ColorOS (Chinese version of Oppo's OS).
CONs
76.7mm wide and hard to use one-hand, downgraded camera compared to OnePlus 13 and a loss of Hasselblad tech, no expandable memory and no desktop replacement functionality or even Video-Out

EDITORIAL: Less then a year after GT 7 here comes a proper upgrade that may signal a shift in Realme's (and it's parent Oppo's) expectations. This is a true flagship phone with a slow USB-C 2.0 port as it's only real weakness. GT 8 Pro is shorter and thinner then it's precessor while bringing a bigger 144Hz hi-res Dolby Vision screen, top performance chip and memory, very long battery endurance and a strong Ricoh tech imaging package that includes a 200MP periscope telephoto. To razzle dazzle, Realme created a removable camera module cover that can be replaced with custom covers of different materials, shapes and colors making this a truly unique offering for a fraction of the price your will pay elsewhere. You should consider buying this big phone if you can find it in your market.

PROs
customizable camera cover system - a true first on the market, fast SD 8 Elite Gen 5 with UFS 4.1 performance, 48hr endurance from a 7000mAh Si-C anode battery with sub-60min 120W (50W wireless) charging. >1900nits bright >500ppi 144Hz LTPO AMOLED with Dolby Vision, IP69 protection. excellent imaging from a 50MP 24mm main + 200MP 65mm 3x periscope telephoto (both with OIS PDAF) + 50MP 16mm fixed-focus ultrawide, up to 4 years of OS updates and very good stereo speaker setup
CONs
almost 79mm wide and hard to use one-hand, scratch and drop resistance may not be flagship-like, no AF on 24mm ultrawide, mediocre 32MP non-AF selfie, mediocre video recording, no expandable memory not video-out or desktop replacement functionality, can get very hot under prolonged heavy load
