New battery and still horrible battery life even after calibrating

[masterx1234]

I'm about to give up on this phone and just sell it. I have a galaxy s6 edge plus and i replaced it with 3 batteries so far and every one of them gives me random and horrible battery life, i did some calibrating by letting it die to 0% and then charge to 100% overnight then repeated 4 times. and still no good. I barely can use my phone normally for half the day even with power save mode on. Anyone know whats going on here? replacing the battery was hard enough taking the phone apart and now this...

First, what do your battery stats show as using the charge?

Thats weird there was no reply button earlier but there is now for some reason, but anyways, The battery stats just show a pretty much stead decline when benchmarking the same app. Also its pretty much random.

Okay, but what apps are listed as having used the charge?

 

[masterx1234]

Screen, phone idle, android OS, android system and audioserver. this is on a fresh factory reset, only app i tested was youtube for battery drain, played the same 10 hour long video at the same brightness and power save mode on medium. results are just random after each charge.

Assuming that you have at least a reasonably good cell signal, and that the battery performance is much the same when using wifi, I'm guessing that there may be a fault with the phone, but I'll move the thread to the S6 Edge Plus forum for comments from other users.

What you did - charge/discharge 4 times (usually 3 times is enough) isn't recalibrating anything, it's conditioning the battery. You do that to a new phone (or battery) in case the battery has been sitting on a shelf for months.

To recalibrate, you can use Battery Calibration (Root), but the phone has to be rooted to recalibrate the battery (the app has to change the system file that holds the voltage of the fully charged battery).

Well i figured out the issue! I decided to take the circuitboard out and inspect the connection of the daughterboard was so loose the connector just fell right off when moving the board, i snapped it back on there securely and now im getting the correct battery life! so all the issues was just a short between the connectors all this time, I am so relieved. thank you guys for the help.
