Hey everyone,
Is it normal to have 99% charge on my battery? I dont think it was ever 100% not even on the first day i got it (christmas). I was just wondering if anyone is also getting this...all i want is my 1%

Same here...99% but i think its normal. When i charge it, it reaches 100% but after some time goes down to 99.

Same here. When I charge and it reaches its limit, it will go to either 99 or 100%. No rhyme or reason as far as I can tell.

Oftentimes, the battery charge indicator says the charge level is at 99%, even though its full. Might be a glitch but it shouldn't mean anything bad. It might stay at 99% for quite some time while charging until it hits 100% (which I think might be normal, or at least that's the behaviour my iBook G4 frequently displays).

If you're paranoid, get the app called X-Charge. It shows the power level of your battery over time, showing you your usage pattern. There are a number of other battery apps in VersionTracker as well, such as Battery Endurance Meter, Battery Stats X, and XBattery.

This is standard for all Apple 'Books. The power management will charge a laptop up to full and then stop charging and let it run off battery for a short while, then begin charging again.

I believe this is to reduce wear on the battery as constant charging damages a Li-on battery, IIRC.

Mine was at 99 for a while and now has dropped to 96 percent for the last week.

ibook...figures

Mulattabianca · Jan 21, 2004, 05:23 AM

i am paranoid. after a dead battery in ibook (it last for 15 mins in the end, before repalcement), i use xcharge.

mine gpes tp 99 %. or actually to 100 %, but it stays 10-15 mins in 100 % charge, then drops to 99 % for days. well, powerbook, but still the same issue.. it stays forver in 99%, not in 100 %

same on mine

Polo2883 · Jan 21, 2004, 07:17 AM

I dont think that its apple's battery malfunction that it stays at 99%...My school sells IBM notebooks and all the students batteries are always at 99% and its a normal thing. So I am assuming that it is normal. But who am I to say since I am still waiting for my ibook.

Superchicken · Jan 21, 2004, 06:12 PM

Mine hovers between 99% and 96% and sometimes jumps to 100... never stays at 97% for long though... I dono, I still get better life than the PCs in my classes so I don't care

O97Bassist · Jan 21, 2004, 07:55 PM

yea well i wast just annoyed at the 99% at the top of my screen by the time so i turned it to time remaining just for the fact that i want perfection and "Charged" is as close as i'm getting...

segaslave · May 27, 2005, 05:53 AM

mine has always been this way, it will go to a 100% rarely but stay at 99%. when i installed tiget it was at a 100% and stayed that way for almost a week i thought it was just a previous bug that finally was fixxed. but no, im back at 99% all of the time again.

ChasingApple · May 27, 2005, 01:50 PM

Hmm, weird. On my iBook Clamshell SE mine always says 100% if it is fully charged.

Voch · May 27, 2005, 02:05 PM

I think it's normal for any lithium-ion battery, including the iBook G3s and probably even way back to the first model to use such a battery (PowerBook 3400 series, I think).
