the only way to read the condition of the battery that i have used , unless you have access to IOS DIAGNOSTICS
is IBackupbot. its a program for mac. maybe those battery health programs give you the same information, i don't know. i never used them
don't forget. if you have applecare or if you ask for a waiver (the waiver " i recently installed iOS ! "always works ) you can simply ask them to send you remote iOS diagnostics, to find out if the battery is bad over the phone
apple only charges $79 for a battery. i don't think its worth the hassle to save $30, just ask apple to give you one
here is a link

what you do is you charge it to 100 %, and take full charge capacity / design capacity * 100
and if its less then 80 % and you have less then 500 cycles , you know you need a new battery
and it might be under warranty
i would of posted from my ipad, but i don't think it works with El captain, it says there is another instance of the program already running, heh
