Storage110 MB50 MB
CPU369 MHz ARM11 processor identified by GSMArena's exact-model production review–
Memory128 MB installed SDRAM from GSMArena, distinct from free application memory. Maker publishes up to 110 MB internal user memory; the configuration records that user-accessible capacity.S60 3rd Edition Feature Pack 2. GSMArena reports Symbian OS 9.3 and a single 369 MHz ARM11 CPU without a dedicated graphics accelerator. Physical RAM capacity is not inferred from the 72 MB free-RAM figure in All About Symbian's test.
Storage typemicroSD expansion up to 8 GB in the maker launch sheet; optional card capacity is not built-in storageMaker launch datasheet states up to 50 MB internal user memory and a bundled 4 GB microSD card. Contemporary tests differ, with All About Symbian finding 76 MB free internal storage and GSMArena just under 83 MB user-available memory. Keep differing firmware/test figures qualified, rather than adding them to nominal capacity.

Main camera3.2 MP autofocus camera with LED flash; maker gives up to 2048 × 1536 still pixelsAutofocus 5 MP Carl Zeiss Tessar, F2.8 aperture and physical focal length 5.2 mm; dual LED flash and physical sliding lens cover. Launch datasheet gives 2584 × 1938 pixels, while the exact guide and GSMArena give 2592 × 1944. Retain this source discrepancy.
Front cameraFront camera for video calls confirmed by maker; no sensor megapixel figure inferredLower-resolution secondary camera supports photographs, video recording and video calls; exact guide does not give megapixels.
Video recordingMaker specifies QVGA video; GSMArena's production test records 320 × 240 at 15 fpsMPEG-4 VGA 640 × 480 at up to 30 fps. Guide distinguishes MP4 TV-quality modes from 3GP sharing mode. Dual LED can serve as a video light; review focus findings vary and are not changed into specification claims.

Video playback (maker's claim)–Up to 5 hours
Wireless chargingNoneNone
Battery life detailRemovable 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.Removable BL-6F, 1200 mAh. Launch datasheet claims up to 210 minutes 3G or 330 minutes GSM talk, 400 hours 3G or 370 hours GSM standby, 5 hours offline video playback and 24 hours offline music. Actual use depends on network, features and battery condition.
Wired chargingSeparate charging connector; compatible Nokia charger. No charging wattage published in the maker datasheet; micro-USB data support does not establish USB charging.Dedicated 2 mm Nokia charging connector. Micro-USB does not charge the handset, confirmed in both full reviews.

Weight detailMaker 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.–

Software at launchSymbian OS 9.2, S60 Third Edition Feature Pack 1, identified by GSMArena's production review–
Software featuresBusiness/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.Integrated FM receiver and FM transmitter; original music, gallery, web, messaging, document viewing and N-Gage software. Firmware, region and operator affect applications; retired connected services are not advertised as current.
Release detailAnnounced 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.Maker announcement on 26 August 2008 plans October shipping, while the datasheet plans Q4. Neither proves the first retail day or month, so release retains 2008 precision, supported by contemporary production reviews. Maker calls it a step forward from N72/N73; review comparisons with N78/N82 do not establish a direct replacement link.
In the boxGSMArena's tested package contains a compact charger, 2.5 mm headset, leather case and 2 GB microSD card with maps; regional contents may differ–
