Normal battery behavior?

First of all excuse my english I am no native speaker.
Quick battery drain. I used Tom Tom Navigation, Display was set to second darkest level. I started driving with 98% battery. After one hour (120 km driven) the battery was drained to 15%. I can’t believe this is normal? Before I used a Samsung S3, the 3 years old battery lasted for 4-6 hours!
If this is normal behavior, the Fairphone is completely useless for me
Any ideas?
