OnePlus 8 Pro long-term review

Battery Life

The OnePlus 8 Pro has a 4510mAh battery. These days, with upwards of 5000mAh starting to become increasingly common, this might not seem like much on paper, but the OnePlus 8 Pro battery has enough juice to power the phone all day.

In our usage, the phone easily went through an entire day. Sometimes, it didn't even really need to be charged even after 24 hours of use since the last charge and could make it through the night and into the next day.

Admittedly, we aren't spending as much time outdoors these days as we would like to so with the largely indoor usage the phone seemed to last much longer than expected. But even with a "normal" workday, we have no doubt that the OnePlus 8 Pro could make it all the way through without giving battery anxiety. Also, this with a massive 120Hz QHD+ display to boot.

The phone comes with the same excellent Warp Charge 30 charger, which charges the phone completely from 0% in just under an hour. This year, OnePlus has also thrown in wireless charging. The phone can charge wirelessly from any Qi-enabled charger but you can also purchase the optional $69 OnePlus Warp Wireless Charger, which provides fast wireless charging times that are quite close to what you can get through the wired charger. It has its limitations, such as a somewhat noisy fan and fixed cable but if you want the convenience of wireless charging and fast charging, this is your only solution for this phone.

Audio quality

There is no headphone jack here nor any audio adapter provided in the box, so we will just move on to loudspeaker sound.

The OnePlus 8 Pro has a stereo speaker system, with one on the bottom of the phone and the other doing double duty as the earpiece. While the speakers sound decent and also get loud enough, the problem with them is that the sound is unbalanced. The earpiece speaker sounds much more prominent for most of the volume range.

The only way to remedy this is to place the phone on a hard surface like a desk so the bottom speaker can bounce its sound off towards you for a more balanced stereo sound. Or you can keep increasing the volume and past 80% or so the bottom speaker suddenly gets loud enough to match the earpiece speaker. However, it does sound a bit different than the earpiece speaker with a more bassy, mid-focused sound than the more treble-focused earpiece speaker, so it still sounds a bit unbalanced.
