The OS is again common—that of Windows Phone 8.1 with Update 1. The beef lies in the 1560 mAh batteries common to both again. However, performance wise the two models offer very close figures. On 3G, the talk time durability lasted close to 16 hours for the Lumia 435 while the other variant gives us 14.5 hours. As for the standby ability, the Lumia 435 can last for seven days as compared to five days of 532. Turning the Glance mode off on the later will give you 7 days standby though. In fact, the Lumia 435 lasts up to 58 hours flat on 3G talk time ad video views.
