My Lumia 620 started experiencing shorter than usual battery life. Before, it can last roughly more than a day with my normal usage, but now, even though it's in standby, it loses battery charge quickly. I even turned off my mobile data for a night just to save battery charge but when I woke up, it lost 10%. I only have 4 apps on background (Twitter, 6Tag, Bing Weather and Day Counter), my Glance Screen is just in peek mode, my location is always turned off as well as Bluetooth and WiFi. It's not only that it loses battery charge quickly, it also charges quickly now. I used to connect it to a wall charger for more than 2 hours for it to be completely charged but now, in roughly an hour, it shows 100%.
I'm assuming it's my battery that I have to replace, but I want to know if I'm the only one experiencing this random sudden battery drain. My phone is in the dev preview for GDR3.
