Battery and charging
Battery1,050 mAh1,500 mAh
Wireless chargingNoneNone
Battery life detailRemovable BP-6MT. Maker brochure gives 1050 mAh, up to 4.4 hours GSM talk and 13 days GSM standby. GSMArena itself inconsistently gives 1050 mAh in its package description and 1070 mAh in its battery section; headline retains the maker figure.User-replaceable BP-4L 1500 mAh Li-Po in the maker specification sheet. Its maxima are 11 hours GSM or 4 hours 40 minutes WCDMA talk, 18 days GSM or 20 days WCDMA standby and 18 hours music. The RM-437 issue1 guide instead lists 10.5/4.5 hours talk and 17/20 days standby; conditions vary. Mobile Tech Review's approximately three-day mixed-use test is not a maker playback claim.
Wired chargingAC-5 charger through a separate small charger socket; miniUSB does not charge the phone in GSMArena's testSeparate charging connector and compatible Nokia charger; the exact guide permits a CA-44 adaptor for older chargers. No charging wattage published in these sources; Full-Speed USB is not a charging-power claim.

Software at launchSymbian OS 9.2 with S60 Third Edition Feature Pack 1Symbian OS 9.2, S60 Third Edition Feature Pack 1. Maker regional sheet calls it S60 3.1 Edition; full production reviews clarify the edition.
Software featuresQuickoffice document viewing, PDF reader, ZIP manager, Team Suite and Active notes. Maker brochure mentions attachment editors, but supplied Quickoffice does not edit in GSMArena's production test; editing requires the separate editor version. Historical enterprise email and internet-call services may no longer operate.Business/personal home-screen profiles; Mail for Exchange, POP/IMAP email, VPN and phone/card encryption. Quickoffice editing in both production reviews; Office 2007 formats required an upgrade in their tests. PDF reader, ZIP manager and Flash Lite 3.0. Historical online services may no longer operate.
Release detailAnnounced 18 September 2007 with planned fourth-quarter availability; Nokia's actual fourth-quarter results confirm first shipments during that quarter. Earliest retail month unresolved, so year precision retained. E50 comparison remains available without an inferred manufacturer successor link.Announced 12 November 2008 with shipments forecast in the coming weeks. Nokia's 2008 annual report confirms E63 shipments during that year; earliest worldwide retail month remains unresolved. The E63 joins the E71 in the maker range rather than replacing it.
In the box–Maker regional sheet lists E63, BP-4L, AC-8 charger, WH-102 headset and owner/quick-start documents; memory card depends on market/channel. Mobile Tech Review's US test instead includes HS-125. GSMArena's package has no USB cable.
