感觉是时候开个满朝文武哭死 1+ 专楼了
太长不看版：1+ 为了续航把 888 的 chrome 性能限制的比 765G 还烂，跑分软件和原神不受影响。尚不清楚 870、865 或更低机型是否受影响。
以下是 9to5google 全文，重点是我自己标注的：
OnePlus flagships are among the most high-power smartphones you can buy, and if benchmarks are your deciding factor, they’re often near the top of any list. However, like many other brands before it, OnePlus has just been caught red-handed limiting the performance of most apps but paving the streets in gold for benchmarking apps.
AnandTech explains that benchmark numbers were not in line with other Snapdragon 888 devices, but specifically, benchmarks run through the Chrome browser. On the OnePlus 9 Pro with its Snapdragon 888, one benchmark scored just 16.8 points, far lower than the similarly-specced Galaxy S21 Ultra and even underneath the Pixel 5 with its Snapdragon 765. This was because, apparently, Chrome and other WebView apps were limited to using just one core for the most part. A new browser, such as Vivaldi, could manage a normal score on the first try but would then jump down to Chrome-like scores.
This latest development is just the latest in a string of AnandTech reports exposing similar tactics from other companies, including Huawei.
What made this stand out was that other benchmarking apps, including AnandTech’s in-house solutions, were not performing out of line. The full report dives deep into the nuances of what’s going on, but here’s the short version.
OnePlus is actively maintaining a list of apps that are, in effect, blocked from using the full power the phone has to offer. There’s no official list of what apps are being affected by this practice, but the tested apps that are impaired include Google Chrome, Twitter, Microsoft Office, Zoom, YouTube, TikTok, Instagram, Discord, Strava, and more.
Here’s the real kicker, though. Benchmarking apps such as GeekBench are among the few apps that have full access to the phone’s power. This is why performance benchmarks for the OnePlus 9 seemed unaffected in tests earlier this year when the phone came out. Making the phone think that GeekBench is actually Chrome or Twitter, though, lowered scores, as seen above. The popular game Geshin Impact was also unaffected, as were some odd outliers like Lyft and Grubhub.
While application behaviour and performance varies case by case, the one aspect that holds true in almost all scenarios is that the OnePlus 9 Pro doesn’t deliver on the full characteristics of the Snapdragon 888. In blacklisted/detected applications, when and if the X1 cores are being used at all, frequencies beyond 2.38GHz are unreachable save for brief booster moments. The vast majority of apps fall back to 2GHz Cortex-A78 cores. This is all a bit ironic as the reason the larger more performance X-series cores were created in the first place was to serve high transient response performance workloads, something they’re not allowed to do here.
AnandTech concludes that OnePlus is doing this, not necessarily to cheat on benchmarks but to boost battery life. In any case, the practice is still impeding the performance of phones that people have paid nearly $1,000 for, leaving the performance lower than competing devices with the same processor.
In response to the story, GeekBench publicly revealed on Twitter that it would be delisting the OnePlus 9 and 9 Pro from its Benchmark Chart, adding that further tests will be performed to see if other OnePlus phones also need to be removed.
Our top priority is always delivering a great user experience with our products, based in part on acting quickly on important user feedback. Following the launch of the OnePlus 9 and 9 Pro in March, some users told us about some areas where we could improve the devices’ battery life and heat management. As a result of this feedback, our R&D team has been working over the past few months to optimize the devices’ performance when using many of the most popular apps, including Chrome, by matching the app’s processor requirements with the most appropriate power. This has helped to provide a smooth experience while reducing power consumption. While this may impact the devices’ performance in some benchmarking apps, our focus as always is to do what we can to improve the performance of the device for our users.
Notably, in our review, we found that battery life on the OnePlus 9 Pro was poor, with Damien Wilde calling it “not all that great.” OnePlus did not directly confirm if this behavior has always been in place or if it was only added after launch. 不过 1+ 到了国外确实还是一堆国内 ROM 的尿性。我 Pixel Launcher 转到 OOS 的，最大的感觉就是杀后台，连前台都杀，我一个 Telegram 或者其他 app 放在前台，息屏之后直接杀掉，你性能是好，开 app 是快，但是也不是你这样随便杀体验就很好的。
查了下 Don't Kill My app，居然荣膺榜二仅次于三星，怪不得。 第三方rom yyds 这不是远古驯猴的方法吗，但现在还是实用
为了888的续航进行限制……不限制原神的话，大概比那些888夏日锁帧的好点，不过文中也提了就算这么搞，续航还是poor……

永远的鬼 个人觉得还是续航重要,以现在app的耗电水平高强度使用基本需要半天一充 降低日常使用体验逼你换机罢了。7t上的骁龙855+也有同样的现象，总不能也是为了控制发热和续航吧 nianiania 发表于 2021-7-10 12:01

现在一加都不能Root了？

不是说某个手机
还是挺怀念当年基本上都没有那个锁死BL不能ROOT的时代
