Hopefully this info helps everybody who came to this thread with a similar issue.
I've verified this with constant observation using CoconutBattery, and my MBP now takes 4 hours or less to charge. The whole point of this trickle charging is to avoid damaging the battery with overcharge once it's near capacity, and is a logical explanation why you'll have much lower wattage when charging during those conditions. The last 80% to 100% is done via "trickle charging", and is supposed to take another 2 hours. The first 0% to 80% is done via "fast charging", and is supposed to take about 2 hours. Lastly, I want to add that I learned it's supposed to take about 4 hours for your MBP to fully charge from empty. I also wound up getting my replacement battery on warranty from iFixit later that day, and the early returns on this new battery are encouraging so far. It took maybe five minutes, and the same test also verified that everything else was in good working order (logic board, MagSafe port, charging adapter, etc). The battery replacement is a ridiculously easy job, and you don't want to be paying them to undo a couple screws anyway.Īnyhow, they ran a test that confirmed the problem was with the battery. They will spend quite a bit of time giving you their disclaimer that they won't do any repairs for you since you've installed 3rd party parts into the system - ignore this. Wound up taking my computer to the Apple Store since they had an opening. One last time I noticed recently was that the LED would slowly dim out once in a while - weird! When I reset the connection, sometimes it'll jump to a higher wattage for charging (like around 12 watts). The MagSafe port is showing its age somewhat it definitely doesn't look very clean. I have noticed this issue from time to time.ĭo you guys think it's the new battery? The power adapter and cord? Or perhaps the MagSafe power port? My power adapter and cord is not as aged I had to buy a replacement about 4 years ago. Coconut Battery reported it was charging with about 3.66 watts. Two, my computer had charged maybe 20% over the course of 4 hours while on power adapter. One, my battery capacity has already dropped off to 5,252mAh (91% of factory capacity) after 5 cycles. I did notice that it was taking longer to charge the computer, but I attributed that to the new battery's size - I was working with 3,528mAh (61% of original capacity) on 1,616 cycles before this new battery.Ĭouple days later, and I noticed two things. The initial result was good: 6,058mAh through the first 3 cycles, per Coconut Battery.

After putting off the upgrade for about a year and a half, I finally swapped out the battery in my early 2011 MBP with new stock from iFixit.
