Inside this reviewed smartphone there is Snapdragon 765G with Adreno 620 GPU, along with LPDDR4x and UFS 2.1 memories, in 8 and 256GB sizes. This is not a weak phone, but not a flagship either, this is a model from a slightly lower shelf.
Taking this into consideration, I cannot complain about the efficiency. It fits into the middle-class. I did not notice any lags or overheating while using the device.
Benchmarks results are not far from what the competitive models from this segment can achieve – I am referring to stronger middle-tier phones with Snapdragon 765G. However, I must complain about the lack of a microSD cards socket. 256GB, in reality 228GB from the start is not that much – I takes me around 2 months to fill this, using clouds at the same time.
I cannot complain about lifespans of Vivo X51. The battery is not the biggest in its class, I would say it is rather small for today’s standards – but it is wild.
I checked how long can Vivo X51 last while being moderately used. I did not turn off neither Wi-Fi, nor mobile data nor Bluetooth – but I was not running apps, only using the phone in its basic role. It survived for four days. When I used it normally – I had to charge it every second day, after 40 hours I was left with a few percentages.
An average SoT is 7-7.7 hours. Of course if you try hard, you can deplete the battery faster – but you will charge it equally fast. Vivo took care about the fast charging and contrary to current fashion, which tells manufacturer to remove them from the box, it adds a 33W one to the set. The 4315 mAh battery will charge in less than an hour, but after 30 minutes we already have 60%. It is good. But, as usual, I must complain… there is no inductive charging.
