    I've been noticing this for a while now, and I just thought it was my battery. I bought a new one, but instead of staying in the 90-99% range, it drops down to 60-75% even in a full service zone

    Try fully charging, remove from charger, turn airplane mode on, reboot, turn airplane mode off. Worked for me. Went from 10 hrs average to about 20.

    Funny, my Lumia 620's battery improved slightly after GDR3. But still not great.

    A big, big battery saver is setting your mobile connection speed to 2G when you don't need 3G/4G. At least, it makes a big difference in my case.

    Also, check running background apps, turn off any not crucial. Then, let the phone run completely dead before recharging.
