Should I be concerned with the battery health at this point?

MacBook Pro :: Battery Cycle Switches Over After 85 Percent

Oct 5, 2009

I noticed that my battery cycle (according to istat) switches over at 15%. So as son as it switches over to the next cycle I plug in the adapter to make the battery run a cycle from 100%-0.(I know the cycle in 100%) But it still switches over at 15%, that means that the battery ran only 85% of its capacity. How can that be? Is it possible to reset (delete) battery cycle data?

MacBook Pro :: Incomplete Battery Cycle Of Charge?

Jun 12, 2012

I bought a MacBook Pro 3 months ago, despite in the first charge I follow the instructions of the store. The problem is that my battery doesn´t complete the cycle of charge, if I disconnect my computer and the value of the battery decrease at 95% 96% 97% 98% or 99% and I plug again the charger to the MacBook Pro, the battery doesn´t charge at 100%. I followed all the instructions of synchronization but the battery remains the same.

OS X :: Battery Recognized - Charging - 0 MAh Capacity And 0 Cycle Count

Oct 5, 2010

I got rained on and my macbook got soaked. I dried out my macbook in an airtight container with some special salt for a few days, and luckily got rid of most of the water issues with my monitor. Unfortunately, my battery or logic board seems to have not been so lucky. My macbook is a one and a half year old 13" unibody, and now won't turn/stay powered on unless it's plugged in. For the first 15 minutes I've plugged in the magsafe charger, the battery is recognized. It says it's charging but stays at 0% (I then get the X over the battery icon). The weird thing is that my previously health battery now has a 0 mAh charge capacity and a 0 cycle count. Is there ANY possible solution to this, or has the damage already been done?

MacBook Air :: Cycle Count On Battery Rapidly Increasing

Mar 26, 2008

So first off, I absolutely love my MBA. Now that we have that out of the way. Since day 1 I've noticed that the cycle count on the battery seems to be climbing MUCH faster than it should.

- I've had the machine 51 days. I was out of the country without it for 9 days so really, I've had it for 42 days.
- According to iStat and System Profiler my battery's cycle count is 37
- According to System Profiler my battery's health is "Good"
- According to iStat my battery's health is at 98% (It started around 96%, has been as low as 94% but seems to have settled in at 97 or 98% for some time now)
- According to system profiler my maximum charge is 5006 mAh. (It's also gone up a bit since the machine was new).

I thought the definition of a cycle was the equivalent of 100% depletion of the battery -- whether that's one long unplugged stint that sucks it dry or 10 really short ones. A cycle is the same as using ~5000 mAh of battery power. I've been really good about keeping it plugged in while I work (the outlet is conveniently located). I've run the battery most the way down maybe 5 times. I do, however, run it down 10 or 20% almost every day as the machine travels with me in sleep mode or spends the night unplugged in sleep mode at my girlfriend's place).

I haven't done any careful testing but it seems though that if I run the battery down just 20% or 30% or so and then charge it all the way back up the cycle count increases by 1. Considering I've only used it for 42 days, and the cycle count is already at 37, I'm worried that it will hit 200 cycles by the time it's 8 or 10 months old. Isn't the point where battery performance starts to wane? Anyone else out there notice a rapidly climbing cycle count?

MacBook :: Full Cycle Battery Usage Vs AC Plugged In

Feb 5, 2009

I had some issues with battery drain while sleeping awhile ago but that problem has been solved. However, ever since that incident I could not be paranoid about the battery life etc.I heard people saying that leaving the charger plugged in is simply fine as long as I do the regular calibration once or twice a month or so. Yet, Apple stated that they do not recommend the laptops to be plugged in. I will be going to a college this Sept and I really do want my laptop to last at least the whole 4 years.

Ever since I have contacted Apple customer service about this Battery issue I have left my Macbook charged up and plugged in while using and letting it sleep. One thing I have noticed is that the battery indicator says 99% and doesn't increase or decrease yet the green light is on. Is that normal? Since this is my first Mac ever and also first Laptop I would like some advice on how to treat the Battery( I know how to do Calibration and such). Is it better to do full cycle usage of Alum Macbook battery than leaving it plugged in all the time? (I unplug it when the Macbook is off).

MacBook Pro :: Won't Find Battery Life Info / Plugged Or Not Plugged

Oct 17, 2009

I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.

I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.
