Useless app - battery runs out after 17 miles – Marathon Trainer - Run/Walk/Run Beginner and Advanced Training Plans with Jeff Galloway Review

I have never commented about an app before but this app has so many flaws that it makes it worthless. I tried it once and my battery ran down so fast that after a 14 mile workout, I only had 20% battery power left. Today I ran a 17 mile workout but I made sure that I was 100% charged, turned off GPS (since I was running a 1.75 mile set route), turned off all other apps from running, turned off all location services and I only had 10% power left after 17 miles. How in the heck am I going to use this app to run 26 miles? This is in addition to many of the other bugs that I have found such as 1) the music slowing down when it tells me to run and should be speeding up 2) Jeff's cues are sometimes off - on my 14 mile run at one point he said you've run 18 miles you can cut out the walk breaks if you feel good..3) the gps mileage is off. I was on my set 1.75 mile route and it said I had run much farther than I know I really had. 4) Sometimes the songs just turn off. I made sure that all of my songs had the registered beats per minute and yet the music just stops until I skip the song. 5) Jeff's cues can not always be heard. Even during the same song, sometimes his voice is so quiet in comparison to the song that you can not hear it. Please wait to purchase until these kinks can be worked out.
