Posting here on behalf of a friend. Must be Dual-Sim, should be able to run apps like WhatsApp, Facebook, email etc, but essentially must have good battery life for browsing and chatting. I could find the following 3 phones, and all from different price points - 1) Panasonic P51 - Recently launched, Quad Core 1.2Ghz, 1GB Ram, 720P screen, 5 inches, but a 2500 mAH Battery. Panasonic P51 - Buy Panasonic P51 Black Online at Best Prices in India - Panasonic: Flipkart.com at 22,000/- 2) Spice Stellar MI-530, nearly the same specs, with a qHD screen (though bigger at 5.3 inches) and a 2550 mAH battery. Spice Stellar Pinnacle Price in India | Mi-530 Specifications, Features and Reviews at 13,500/- 3) Salora POWERMaxx Z1 - Lol at the name, but it does have a 3200mAH battery and a 1Ghz Dual Core processor with 512 MB of Ram. A 4.5 Inch qHD screen and the lowered specs do make for a phone that should have an excellent battery life.
