Any reason why this happened? Would letting it run all the way down and then charging solve this?
My computer (Macbook Pro) does that if i leave it plugged in too long. It shows full charge at 99, then 98, then 97 and so on. Prevents overcharging I think. Do you leave your phone plugged in for extended periods? May be the same thing.
You could just turn off the battery percentage indicator and this problem goes away.
No, I'm not trying to be snarky. Just far too many people are overly concerned about a number that is far from exact, yet they expect it to be precise. Thus they get worried, upset, etc. about it.
Disabling this silly number makes these problems disappear.
On Friday night I plugged in at around 5:30 and forgot the phone at home on Saturday.
When I unplugged (lets say 26 hours later) I was at 93%.
I think its just a feature that saves you from overcharging the battery. I believe my older blackberry did this as well, once it reached 100% after some time it stopped charging.
But at some point the charger should kick back in. It shouldn't indefinitely stop charging.
my android did this, i believe its not trickle charging to keep the battery topped up. prevents over charging the device. i think maybe related to the high speed processor so the device doesnt need to overheat.
all in all its annoying
My phone occassionally has done this in the past. Usually it stops charging at 96%. What I normally do is unplug the phone and plug it back it in. Once you plug it in, it will continue to charge until it reaches 100%. Turning off the battery % is also a good idea.
Same with my 4s
This morning it was 98%
Removed the charger, and put it in another wall socket, and it went to 100%
After about 5 minut
Never had this on my 4, only the 4s
Macbooks does the same, it has to do with re-calibrating the battery.
For some reasons all the iphone 4S does this now.
My new iPhone 4s is doing the same thing.
My 4s does this too occasionally. A bit annoying. I unplug and let it drain to 90% then plug it back in and it goes back to 100%.
Noticed this myself on my 4S. Had it plugged in over night and it was only at 98% - was strange. Unplugged it and plugged it back in and it charged up all the way.
I wonder if this is a new feature or a bug?
Thinking about it I remember it happening on my 4 before...hopefully letting it drain down to the end will help solve this.
It was happening to my 4S too, 2 or 3 days in a row. Left it charging all night, in the morning it was at 96%.
Then, all of a sudden it went away and now it's 100% in the morning.
You guys never noticed your notebooks doing this? They let the charge leak down to 95% while displaying fully charged, then once the percentage hits 94% the charging kicks in and it goes back to 100%.
Same thing on the phone.
When this happens just unplug the phone and then plug it in again. It should charge up to 100% then.
Yeah, this happens to me too. It's actually a good thing I think. Like it has happened to me on my MacBook since the day I got it, and I read that it was a good thing for batteries. Continuously charging it to 100% can reduce battery lifetime, where as giving batteries a good workout can be beneficial for the batteries. Now I'm not chemical engineer, so please don't take my word for it, but that's what I've read on some tech blogs.
You'll be fine, just an indicator that your battery is slowly dying
Follow apple's calibration procedures for the iphone and the problem should go away.
This time my phone full charged at 99% but then took it off and charged to 100%
Luckily...hope that fixes it
This morning I unplugged mine and it dropped to 97%. Lowest % I've seen yet. My 4 never did this.
I've seen it mentioned in other threads, but my phone drains quite a bit faster when I start the day at the 98%. If I plug it back in for a few minutes to get it back to 100% it drains at a much slower rate.
Think the best bet is to let it die and charge it back up and see if it charges up to 100%
It's odd that it does this but guessing it doesnt cause any harm.
I've done one complete discharge. Didn't seem to help. I've always plugged my phones in over night.
I've only seen a couple days stay at 100% when I unplug.
Indeed. I plan to do that tonight, running my phone down all day today. ;-)
