I bought a prepaid Lumia 435 September of this year. Recently I noticed I would plug it in at night when I go to bed with anywhere from 5%-15% battery life and when I wake up at least 7 hours, if not more, it'd be only 80%-90% charged. Last night my phone sat on the charger and I woke up with 20% and it sat on the charger all day and fluctuated between 23%-34%. I'm a prepaid customer and I don't know if the same rules as restrictions apply for prepaid customers as they do monthly customers? My mom had that problem with her Samsung through Koodo and they gave her a loaner, sent hers away for repairs and she received it back within two days... Can I expect he same courtesy with my phone?
