OnePlus 15 Review: A Phone With Two-Day Battery Life

On days with mild use, I’ve 70 % left by bedtime. When I spent extra time on the cellphone, utilizing it for music streaming, navigation, and Instagram Reels-ing, I typically ended with round 60 or 50 %. I’d go away it on my nightstand with out bothering to plug it in, a refreshing change of tempo. Over the course of two days, I hit a tremendous 10 and a half hours of screen-on time.

This could be the perfect battery life on a flagship smartphone at this time within the US, particularly while you pair it with the extremely quick recharge instances. OnePlus stays one of many solely firms to incorporate a charger within the field—principally as a result of it is the one method to benefit from its SuperVooc fast-charging know-how. I used to be in a position to ramp from 15 to 80 % in half-hour (50 % in quarter-hour). It’s laborious to fret a few lifeless cellphone should you do not thoughts maintaining the cumbersome charger in your individual (is a folding prong an excessive amount of of an ask?).

But there’s at all times a compromise someplace. If you are a fan of wi-fi charging and are particularly fascinated with Qi2 smartphones that use magnets (like Apple’s MagSafe) for extra handy and quicker charging, you will be disenchanted right here. The OnePlus 15 helps wi-fi charging, however solely the usual Qi know-how. OnePlus is promoting magnetic circumstances as a salve, however not like Samsung’s present crop of top-end telephones, this does not even flip it right into a Qi2 Ready cellphone. It will solely cost at gradual Qi wi-fi charging speeds. (You can purchase OnePlus’ proprietary wireless charger to fast-charge, however that is a separate buy, and that wi-fi charger will solely recharge choose OnePlus gadgets rapidly.)

The beefy battery and super-fast wired charging could outshine the lackluster wi-fi charging, however now it is time to discuss concerning the second most spectacular feat of the OnePlus 15: efficiency.

This is the primary smartphone within the US to make use of Qualcomm’s Snapdragon 8 Elite Gen 5, a processor we’ll see in most high-end Android telephones in 2026. The benchmark numbers are wonderful. In a Geekbench 6 take a look at, the OnePlus 15 is formally the primary cellphone to cross 10,000 in multi-core CPU efficiency, even besting the iPhone 17 Pro Max. However, the iPhone nonetheless had a slight leg up in single-core efficiency (it is also usually extra environment friendly).
