"NEW" Battery won't retain charge

I replaced the battery, then completed the process of "conditioning" the battery by charging, then letting it drain completely. I did that 2X. At first, the battery had amazing run time-- more than 1 day. Now, one week later, it drains in less than 2 hours sitting idle.

Here is the snapshot. I wonder, since this battery was manufactured in 2014, if the battery is worthless anyway? Perhaps I need a refund from Ifixit?

Update (02/24/2023)

OK, Here is the new snapshot.

Thanks for your help!

@danj-

Sorry for the delay- I was on the west coast visiting my first grandchild.

You: "Now if you had the system shutdown during charge and you gave your system at least 10 hours of charge the battery heat lever should be lower than this. So did you not wait? Is the charger warm?"

Should I charge the battery for 10 hours and then check battery temp? Ans what would I expect a normal charging temp to be?

I will add that I returned home with the machine plugged in and fully charged. I used it for 2 hours with gargeband to drain the battery. When it has about 20% left I put the iMac to sleep and closed the lid. When I returned this morning the battery was completely drained. I am charging now- the battery is at 13% and the temp is 29C.

Here is screenshot of my system and current battery info:

Where did you get this battery?

tarafından

The battery came from i Fixit.

I have a reasonable amount of experience repairing my personal computers and phones since the 1980s. I’m good with a torx. Etc. I think the previous answer would give me insight, but anyone know why it would work fine for 1 or 2 days and then completely fail? Also, if I could determine the hotspots and thus see where the power drain might be, it would be a guess. Perhaps it’s time for a new laptop?

@chris036 - It looks like the one you posted here is the same as well.

hello Chris,

definitely the problem lies with the electricity (which seems natural to most of the forum members but ...) few know where to look. Well, this can be understood in at least two ways: mathematical and diagnostic, or in the second case, organoleptic. It all depends on what tools you can use for this purpose. As a workshop, I definitely recommend the mathematical model. Such a large leakage must originate in the electronics of the motherboard or in the battery driver. You need a multimeter, lab power supply and some knowledge of current. If you're not a microelectronics expert, the organoleptic method remains. Charge the computer to 100% and leave it turned on. At the same time, turn on the clock (stopwatch, write down the start time, whatever). After about an hour, note the usage of your computer. If possible, find a warm place. The housing is made of aluminum and conducts heat well. You shouldn't have any trouble locating the hot spots: the screen wing, keyboard, maybe the bottom or trackpad. After this time, charge the computer again to 100% and put it to sleep. After about an hour, check the wear and, as before, try to locate the warmest spots. The conclusions will come by themselves. The rest, after testing.

chris036 - Let’s get a better view of things, install this gem of an App CoconutBattery take a snapshot of the main window with the battery tab opened when your charger is plugged in under charge (Amber LED). Post it here for us to see.

Update (02/22/2023)

Lets let the system charge over night after a full shutdown and take a fresh snapshot in the morning.

Other than a low battery it does look healthy besides the date issue which I think might be a residual effect from the old battery. Let’s wait till the morning to attempt fixing that.

Update (03/03/2023)

@chris036 - Your battery appears to be OK, the charging wattage is within what I would expect, the temp as it’s charging is expected as well. The only issue was what I have to assume was the CoconutBattery snapshot you had posted before was just at the end of the charge cycle while the battery was still warm but not charging anymore.

So why is there a problem? I’m suspecting you have some applications running which are consuming the power as you haven’t been shutting your system down fully, just putting it to sleep mode can still be an issue as background apps can fire up draining your battery.

So tonight let’s give this a try to see what you encounter in the morning. First you want to make sure your battery is fully charged and you do a proper shutdown from the Apple menu, the MagSafe cord LED should be green and now disconnect the cord.

In the morning after restarting your system launch CoconutBattery again and take a fresh snapshot let’s see where things are then. I’m suspecting it will be as you left the system the night before. If it is then we need to figure out what application is running when you retire for the night. If on the other hand if the battery is run down you have a short which is slowly draining the power. I would inspect and maybe replace the MacBook Pro 13" Retina (Late 2013-Early 2015) MagSafe 2 DC-In Board

Thanks for helping me on this....I'll report back in the AM

I inadvertently left the Laptop unplugged, but will recharge fully today and report back tomorrow. Thx!

@chris036 - Did you note you posted a second copy of the first snapshot? You may need to take a fresh snapshot or locate the second one.

@chris036 - Good news the battery appears healthy! The only issue I see is the batteries temp is quite high! Now if you had the system shutdown during charge and you gave your system at least 10 hours of charge the battery heat lever should be lower than this. So did you not wait? Is the charger warm?

If you had then there is something else going on here. What is your workflow? What is your RAM and the size of your storage and how much free space does it have.

OK let’s give the system another 8 hours fully shut down and take one more snapshot.
