It's been more than two years since the Snapdragon 870 processor was released, but I think there are a few things worth sharing on the question of whether you need to replace your phone.
First of all, in terms of the raw computing power of the processor, the Snapdragon 870 has basically no problems in daily use to date. I remember when the Snapdragon 870 was released, its GeekBench performance score was around 1200, and now it basically runs smoothly on a daily basis.
Especially compared to the Snapdragon 888 two years ago, only those users with higher performance requirements have a good reason to upgrade to the Snapdragon 888 processor. After all, the 888 processor heats up when it runs, and the performance is not as good as it could be, and there has been a big difference compared to the 870 processor in the past two years.
As a result, for most users, the Snapdragon 870 processor still performs well in current day-to-day use. While the new processor may bring some additional features and performance boosts, the 870 processor is still enough for the average user in the short term.
Of course, for some users who have higher requirements for the performance of their phones, they may consider upgrading to a new generation processor for better performance and experience. But for most users, the Snapdragon 870 processor is still powerful enough for now, and there's no need to rush to change phones.
