Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: CPH2655 and regional variants
What that covers: OnePlus phone; OxygenOS version, region, alert slider/key, charging protocol and carrier certification vary.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Tier — flagship (alert slider): The flagship OnePlus — top chip, OxygenOS over Android, and the signature alert slider (a physical 3-position switch for ring/vibrate/silent). If ringtones behave oddly, check the alert slider position first; it overrides on-screen sound modes.
SUPERVOOC fast charging: Very fast wired SUPERVOOC charging — but it needs the included OnePlus SUPERVOOC charger AND cable to reach full speed; a generic USB-C charger charges it much slower. Wireless charging on this flagship tier.
OxygenOS: OxygenOS differences from stock Android are software, not faults. eSIM support varies by region/model.
Connector: USB-C. A cable that fits is not necessarily a cable rated for this phone's charging speed — USB-C carries several power profiles and a cable built for data will charge slowly or intermittently while seating perfectly.
Modem: 5G capable. In marginal 5G coverage the phone hands repeatedly between 5G and LTE, which costs more battery and generates more heat than settling on either — so the preferred-network setting is a real diagnostic lever rather than a preference.
Platform: Android, with a manufacturer interface layer over it. Battery optimisation and background-execution restrictions are applied per app and are far more aggressive than on iOS — which is why 'set this app to unrestricted' is a real fix here and has no equivalent elsewhere.

Exact questions

Questions that only have an answer for the OnePlus 13

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

My OnePlus 13 isn't charging as fast as advertised.+

SUPERVOOC's headline speed needs the OnePlus SUPERVOOC charger and its specific cable — a standard USB-C charger or a third-party cable will charge it at a much lower, ordinary speed. Use the in-box charger and cable, and note a hot phone or a case can throttle charging to protect the battery. Also check that Settings has fast charging enabled. It is not a fault; SUPERVOOC is proprietary and requires the matching brick and cable.

Structured depth, not empty permutations
