Good news, then: it's already time to start looking ahead to OnePlus' next handset. Though OnePlus generally announces its new models somewhere between summer and autumn, we're already seeing early rumours and leaks trickling out about the OnePlus 5.
What's in store? Well, we're big fans of OnePlus' approach to making mobiles - delivering value and developing its devices based on user feedback - so we've got our fingers crossed for some big developments.
Early evidence suggests some truly tasty treats are on the cards - but it's worth pointing out that much of what's known so far is either speculation, or based on speculation.
In any case, here's the juiciest gossip we've got on the next OnePlus flagship.
WHAT WE KNOW
Yes, we know you were all expecting the OnePlus 4, but the company's next hero phone will instead be called the OnePlus 5. Why? Not, as many outlets have reported, because the number four is considered unlucky in China. Apparently it's because a number of OnePlus big wigs are massive fans of former NBA player Robert Holly, who wore a #5 jersey.
Could it be true? We're more convinced by the former theory. Apple didn't seem too worried with the iPhone 4, nor Samsung with the Galaxy S4, but they aren't Chinese companies. OnePlus might feel a little different about calling their phone something that sounds very much like "death" in Chinese.
The 3T packed a 5.5in 1080p AMOLED, which was no bad display. For the next-gen OnePlus, early evidence was hinting at a slight downsize to 5.3in, in favour of a resolution upgrade. A 2K AMOLED would make sense, given that many of OnePlus' competitors now pack QHD displays and OnePlus hasn't upgraded its flagship's screen resolution since the original OnePlus One. Later reports have suggested 5.5in will still be the norm, though.
Unlike the metal shells of both the OnePlus 3 and 3T, if rumours prove to be true the next-gen OnePlus handset may well opt for something different. Some suggest it'll be glass, while others - perhaps with more veracity, based on the build of one version of the OnePlus X - point towards the possibility of a ceramic shell on the OnePlus 4.
The trend for ever-skinnier display bezels was kicked off by Xiaomi, but LG and Samsung have brought it to the mainstream. OnePlus could be set to follow, if rumours about a handset that's mostly screen end up being true. There will be no physical home button, and the fingerprint sensor will be relocated to the back of the phone, in order to make room for an all-screen design.
If Tweets by OnePlus co-founder Carl Pei are anything to go by, the next OnePlus smartphone will still have a headphone jack. In a poll Pei ran, 88% of respondents voted in favour of the jack and, given OnePlus' intimate connection with its loyal user base, it would be quite the PR foot-in-mouth moment to go against that tide of opinion.
Leaks and rumours aside, given how nippy the fantastic OnePlus 3T is it's a pretty safe bet that the next-gen OnePlus flagship will be even speedier. Present know-how points towards two models - one with 6GB of RAM and one with 8GB, and it's been confirmed by Qualcomm and OnePlus CEO Peter Lau that the OnePlus 5 will carry a Snapdragon 835 processor. That should mean a significant upgrade on the Snaprdragon 821-powered 3T.
Lau also revealed that an OxygenOS update will manage app performance so that "the apps you use most are ready to go when you turn on the OnePlus 5" will less-used apps are deprioritised to increase the smoothness of the experience.
A leaked web store listing seemingly confirmed a 4000mAh battery, too.
There's little known as yet about any shooting tech upgrades that'll grace the next OnePlus. That hasn't stopped some speculating, though, about the possibility of a dual lens set-up on the next OnePlus. Why's that significant? Some are suggesting that there will be augmented and mixed reality smarts as standard. What form this might take is yet to surface, but a pair of lenses would be a key first step to the necessary depth perception. The latest signals point to a 23MP main camera, sourced from Sony, but it's unknown if the secondary snapper will match it for megapixels, or if it will be smaller.
Either way, camera experts DXO are on board to offer advice and make the OnePlus 5's cameras the best they can be. The only OnePlus phone on the DXO leaderboards right now is the OnePlus 2, with a score of 76 - some way behind the 90 scored by HTC's U11 and Galaxy S8's 88.
The OnePlus 3T arrived last autumn, not quite as a stop-gap model but not the massive leap forward from the OnePlus 3 many were expecting. The OnePlus 5 will arrive less than nine months later, in the summer of 2017. The company confirmed as much to The Verge, but hasn't yet narrowed that window down to something specific. As soon as we know, we'll update this article with a concrete date.
