"Good" and "horrendous" are relative terms - what's fantastic to one could be terrible to another.
Eight hours from 100% to 50% (which is about what your graph shows) is good for any Android phone. BTW, NEVER let the battery drop much below 40%, or you'll be sending it in for a new battery. Lithium batteries are not deep discharge batteries. (I've always had my phones set to turn off at 38%, but I normally start recharging between 50% and 45%. And I have batteries that are years old and still working fine. Even my 2004 V551 still has the original battery, even though it's about as useful as a buggy whip by now.)
Agreed. I airways let every phone I use go down to 5% before I recharge then and I have never had to replace a battery. I've done this on all the of my S7 Edge phone's. Every iPhone since 2007 and my Note 4/Note Edge. All are perfect to this day. My old iPhone 3GS still shows its battery capacity as being 98%. Just charge the battery when you like to charge. 5% wont harm it in any way.Not sure where you got that info from. I have always charged my phones to 100% going down as little as 5%. No problems at all with cell phones with at least 3 years use each kind.
