Phone getting hot and draining battery? May be you should try disabling GPS when not in use.

I wrote a review on Android My Tracks App:

This is for Samsung Galaxy Note 3 SM-N900T T Mobile current version
experiencing "waiting for gps"
Andriod 5.0
Google Play Services 7.5.74
My Tracks 2.0.10
Kernel version 3.4.0-4086253

See https://code.google.com/p/mytracks/issues/detail?id=1579

Based on suggestions by others, I did the following before opening My Tracks.
1. Close all Apps which use GPS.
2. Open App GPS Status.
3. Background Behavior is set to Use GPS when screen is off.
4. Leave GPS Staus App running after ensuring that all satellites are green and error is lowest.
5. Open My Tracks.
6. Touch he GPS button and wait till it is blue.
7. Touch the Record button..

Open Maps tab and ensure that there is no message "waiting for GPS"
The App should work as you expect. Problem is that by itself My Tracks App is not enabling GPS but looking for GPS signal. It is ridiculous that Google cannot fix its own App. It used to work fine in Android 4.3, started acting up in Android 4.4 and needs this work around to work in Android 5.0.

There is one other thing I found. The battery was draining faster without this because My Tracks was looking for signal constantly. I disabled GPS after I no longer needed it. After using GPS for 1hr15min and using the phone as usual battery life is now 59%. Projected battery life is 13hrs. Phone is not getting hot now.
