Even idling you'll be lucky to get two a full two days. With usage, battery is pretty sad. You can get a modest day out of it but you have to work around the battery. Eventually you'll learn to use it sparingly to get it to last the whole day. Don't be afraid to charge it when you can (even if only for two minutes)- the battery won't be negatively affected. For 15USD you can buy two batteries on amazon (brand onite) that come with a direct to battery wall charger. Not sure if they're as good as the stock battery, but damn that's a deal.
