In moderate use, you’ll comfortably get through a full day on a single charge, and quite possibly through to a second. Media will take an extra chunk out of your battery life, but not as much as you might expect.

Either way, the onus here is wholly for that main sensor to come good. In general, evenly lit conditions, the results are just about acceptable given the low price tag. There’s a reasonable balance to shots, with Oppo’s customary natural color science. It also isn’t unusual to find such a low-resolution display at this price, of course. The Alcatel 3L, the Nokia 3.4, and the Moto E7 Plus share this particular spec. The Oppo A15 is powered by a 4,230mAh battery, which is ample for a phone at this end of the market. You’re unlikely to be indulging in hours of gaming given that humble processor, and even if you’re a total video-streaming hound, the 720p output shouldn’t prove too taxing. An hour of Netflix streaming with the screen set to full brightness sapped between 5% and 8% in our tests – which is weirdly variable, but generally pretty strong. The Sony Xperia L4 lost 12% under the same circumstances, while the A15 also pips the likes of the Honor 9A (which lost 8%) and the Realme 5 (on 9%).The Oppo A15 comes with ColorOS 7.2 out of the box, which is a custom skin running on top of Android 10. It’s a reasonably clean and smooth take on Google’s OS, albeit one that suffers from garish icons and somewhat jumbled menus. While it’s tempting to consider such a cheap, solidly built phone from this dependable brand, it’s worth separating price from value. Put simply, there are far better phones available for the same – or just a little more – money, including the Moto G8 and the Oppo A5 2020.

Oppo Mobile UK managing director Kevin Cho claims that the Oppo A15 has been “designed with users’ social networking and entertainment needs in mind”, which explains the presence of a large 6.52-inch IPS LCD screen. The Oppo A15 comes with an ostensible triple camera setup, featuring a primary 13-megapixel lens supported by a 2-megapixel macro and a 2-megapixel depth sensor. Still, ColorOS is a suitably customisable UI, so you can tweak things to a reasonable degree of satisfaction. There isn’t much in the way of bloatware either, and Google’s Chrome, Calendar and Gmail apps handle their respective duties in place of inferior alternatives. It’s worth noting that the Nokia 3.4 and the Alcatel 3L both squeeze in an ultra-wide lens – although it’s fair to say that cheap ultra-wides are never particularly great. With that in mind, the argument for a single, decent wide lens is strong at this end of the market. One of the areas in which the Oppo A15 does deliver is battery life. A fairly large 4,230mAh unit serves those modest components well, happily taking you into a second day of use before needing a top up..The culprit is the humble MediaTek MT6765 CPU, with a paltry 3GB of RAM supporting it. A Geekbench 5 multicore score of 930 is very low, even when compared to other budget phones. There’s no getting away from the fact that the Oppo A15 is a super-cheap phone. Its entirely plastic design is almost completely without embellishment.
