Galaxy Nexus only charges to 99%?
Mine does the same. Extended battery?
Nope regular battery.
I only ever get to 99%. I thought this might be because it shuts off charging when it hits 100%. I guess anything slightly under, no matter how minute, isn't 100%.
I'm sure someone else will be able to shed more light on the missing 1%.
Same, with extended. First time I plug it in, it does go up to 100, but then drops to 99 and then hangs there. I assume it's some mechanism to prevent overcharging and damaging the battery.
I believe it is an overcharging "thing". I've seen it at 100 a few times, but since its usually charging overnight, I usually come down to 99. I think it charges to 100 and then stops and probably cycles back up again if it dips to 98 or something.
I actually happened to catch it.
Started charging it, happened to check up on it when it was at 98% (and then 99%) and "charging". Came back a little while later and it showed 100% and "charging". Let it sit a little while longer and it was at 99% and "charged".
I think Tim is correct and it stops charging the battery once full to prevent overcharging it and potentially damaging it.
I see this too... but if I unplug the phone and replug it in, it will often go to 100%.
Also, note it will sometimes say 100% (charging) or 100% (full) or something to that effect... like charging that last few percent is a lot of work... same with discharging the last few percent it seems...
I found this quote in another forum when I was looking for Battery Calibration for the Galaxy Nexus. I think its relevant.
