Slow charging and sudden battery life loss

Slow charging and sudden battery life loss

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. The initial result was good: 6,058mAh through the first 3 cycles, per Coconut Battery. 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.

"Review this Apple T/N Apple Portables: Troubleshooting MagSafe adapters see if your MagSafe adapter is the correct one and the connector interface is clean and in good working order.

Sadly, it sounds like you have a charging logic issue within the system. Lets see if we can isolate the fault. Follow this IFIXIT guide MacBook Pro 13"" Unibody Early 2011 Logic Board Replacement for the first four steps, once you disconnect the battery jump down to Step14 disconnecting the battery charge indicator ribbon cable place a piece of tape across the connect so the ribbon stays disconnected. See if that changed anything."

"I’m having your same original problem. And I just bought MBP 13 in June - about 4 months ago. But I use excessively all day doing cloud computing database work, and evenings watching YouTube movies whatever. That battery is like 4 years old in battery years since it’s been working 16-20 hrs a day for 4 months. If there’s a chance this level of use will ruin my system beyond the battery - I better find out now b4 too late.

THANKS this was very helpful. Heading to Apple store for a level 5 diagnostic. Lol #trekkie"
