Battery and charging
Battery1,500 mAh–
Wireless chargingNoneNone
Battery life detailBP-4L 1500 mAh Li-Po; maker datasheet claims up to eight hours GSM/six hours WCDMA talk and 23 days GSM/29 days WCDMA standby. Review endurance varies with use; not video playback.Removable BP-4L. Maker guide 9255175 accessory chapter lists 970 mAh, conflicting with the 1500 mAh battery photographed and described in GSMArena production test. Headline capacity omitted pending resolution. GSMArena obtained six days of moderate mixed UMTS use, an attributed test rather than a standardised maker claim.
Wired chargingCharges through micro-USB, including a compatible USB data cable; exact guide says cable charging is slower and a USB hub may not work. No charging wattage inferred.Dedicated bottom charger socket; maker guide lists AC-3/AC-4/AC-5 and CA-44 compatibility, plus CA-70 charging connectivity cable. No charging wattage or generic data-port charging claim inferred.

Maker's 2009 sustainability report lists it among products launched that year, and August production reviews establish retail units. Earliest maker-supported on-sale month unresolved, so year precision retained. No E51 predecessor link inferred from secondary descriptions.Announced 12 February 2007 with Q2 availability planned. Nokia annual report confirms shipments during 2007; GSMArena production test was published 4 May. Earliest worldwide on-sale month remains unresolved, so year precision retained. No predecessor relation inferred without explicit maker wording.
