Both reviews praise the solid slider, comfortable keypad, sunlight-readable screen and responsive software. GSMArena criticises noisy camera images, the quiet loudspeaker and a slow unaided GPS cold start; TechRadar finds the camera adequate for casual use. Battery tests use different workloads: GSMArena gets just over two days of heavy use, while TechRadar recharges after three moderate-use days. Office support differs in the reports: GSMArena requires an editing upgrade, while TechRadar describes document creation.
2.4-inch 320 × 240 LCD with up to 16 million colours in the maker datasheet; TFT identified in GSMArena's production test. The physical screen is portrait-oriented; resolution is stored long side first for comparison.

Battery life detail
Removable BL-4U 1000 mAh Li-Ion. Maker maxima are 7.5 hours GSM or 3.5 hours WCDMA talk, and 11 days GSM or 14 days WCDMA standby. These are network operating conditions, not video-playback claims. GSMArena's stationary GPS/display-on test lasts six hours.
Wired charging
Separate charging connector; compatible Nokia charger. No charging wattage published in the maker datasheet; micro-USB data support does not establish USB charging.

Weight detail
Maker launch sheet rounds size to 107 × 49 × 13 mm and gives 121 g. GSMArena measures/lists 107.5 × 49.5 × 13.6 mm; that greater precision is review evidence, not a silently substituted maker claim.
Materials
Stainless-steel rear cover and slider body; numeric keypad slides out below the display. This is a mechanical slider, not a folding or flexible-display phone.
Colours
Grey Steel and White Steel in original maker launch sheet; regional availability varies
Buttons
Numeric keypad, navigation control and one-touch Home, Calendar, Contacts and Email keys; dedicated shutter and side volume controls
Sensors
Accelerometer and ambient light sensor
Speakers
Built-in loudspeaker and FM/Visual Radio; GSMArena reports no RDS. Compatible wired headset serves as radio antenna.
Software
Operating system
Symbian
Software at launch
Symbian OS 9.2, S60 Third Edition Feature Pack 1, identified by GSMArena's production review
Software features
Business/personal home-screen profiles; Mail for Exchange, Nokia Intellisync and POP/IMAP email. PDF reader, ZIP manager and office-document viewing; editing required a Quickoffice upgrade in GSMArena's test, whereas TechRadar describes document creation. Exact tested software/upgrade status differs between reports. Historical online services may no longer operate.
Release detail
Announced 16 June 2008 alongside E71, with July shipments forecast. Nokia's 2008 annual report confirms actual E66 shipments during that year; earliest worldwide retail month remains unresolved. No speculative E65 predecessor relation added while that model is absent.
