OnePlus 15: problems, parts and running costs

Checked: 2026-10-19

Summary

Owners most often run into three things: the phone overheats and throttles under sustained load, US software updates lagged months behind other OnePlus models in early-to-mid 2026, and the cameras are a step back from the OnePlus 13 despite the same 50 MP numbers. Keeping it running costs nothing in consumables — there are no subscriptions and no published battery-replacement price. It is a good buy below $890 on the street and a hard sell above $1,000 unless two-day battery life is the only priority.

Common problems and fixes

Overheating and throttling under sustained load — Android Authority’s standard 3DMark stress test never finished: the phone shut the benchmark down about two-thirds of the way through, locked out non-essential apps until it cooled, and logged 52.7°C on the surface [5]. Android Police recorded 47–50°C on repeated 20-minute runs and still hit an overheat shutdown after a software update [7]. After OnePlus’s thermal-curve update the test completes, but sustained performance sits near 60% of peak, close to the older OnePlus 13 [6]; real games stay much cooler at 33–41°C [8]. Fix: keep the current software and treat peak benchmark numbers as short bursts — OnePlus says everyday use and gaming stay within normal thermal limits [5]. The 1-year US warranty covers defects [2].
US software update delays — owners reported being stuck on the February 2026 security patch into May 2026 while the 15R, 13 and 12 moved on, and some January posts still showed the December 2025 patch [13][14]. Workaround owners used: the third-party OS Updater app with manual ZIP installs [13]. Update timeliness is not a warranty matter.
Dual active eSIM still missing on US units — advertised at launch, delayed past the Q1 2026 estimate to Q3 2026, and still unavailable on US units in July 2026 even though the Indian variant had it on the same update [10][12]. Workaround for now: one nano-SIM plus one eSIM.
Cameras down from the OnePlus 13 — all three 50 MP sensors are physically smaller than the 13’s, low-light shots show more grain, and owners report color and processing issues after the Hasselblad split, including distortion around faces [17][9][3]. No fix; it is a hardware change, though PCMag still calls the output a step forward for OnePlus in absolute terms [3].
Pre-applied screen protector — the default film is low quality and collects fingerprints; PCMag recommends removing it [3]. Fix: peel it off and fit your own.
Occasional software bugs — owners report a smart sidebar that stops working and random glitches; disabling the problematic feature resolved them [18].

Parts and consumables

No replaceable parts or consumables reported.

Yearly running cost

Not enough data. There are no consumables, pods or subscriptions, and no battery-replacement price has been published. The included 80 W SUPERVOOC charger covers charging, and third-party USB PD chargers work at up to 55 W, so a lost charger does not force a repurchase from OnePlus [4]. OnePlus claims the 7,300 mAh cell holds 80% capacity after four years of use [3].

When it is a good buy

US launch pricing in November 2025 was $899.99 for 12 GB + 256 GB and $999.99 for 16 GB + 512 GB [1]; PCMag still listed the $899.99 MSRP in May 2026 [3]. Below $890 on the street the trade-offs are easy to accept, and owners advise waiting for a discount rather than paying full price [9]. At $999.99 it sits well under the Galaxy S25 Ultra ($1,299.99) and the Pixel 10 Pro XL ($1,199.99), but those are the better picks if cameras, 7-year software support or carrier stores matter — Samsung offers a better display, S Pen, longer support and carrier availability [3][20]. Above $1,000 it is hard to recommend unless two-day battery is the only thing that matters [3]. Tom’s Guide mentioned a $100 trade-in credit at launch [19]. The 1-year US warranty can be extended with paid plans: Accidental Damage Protection $129 for 24 months, Screen Protection $69 for 12 months, Extended Warranty $39 for 12 months [2].
