How long does the battery lasts usually (not the records) as mine does for approx 4-6 hours of I continually use net, so is it my battery or its normal??

Well nokia 520 does't really have a large battery capacity,when i use the internet my battery also lasts about 5 hours,so it's normal,if you need more power,i suggest you to get a power bank
