Why does my phone never it 100% charge?

So for the past 2 days I've charged the phone at night while I sleep and every morning I pull it off the charger and it's instantly at 98% never 100%. Why is this? The light is green when I unplugged it.

Seems to be an HTC issue happened with my sensation when It just came out gonna take a microsoft update or 2 to fix it. Unplug it at 99 then replug it in it will go to 100 in time

Ah ok. yea i tried to bump charge bc when I had my htc incredible (1st gen) it had the same issue. You think they would learn LOL

Mine's reached 100 before. I believe the battery automatically stops charging after it hits 100 for some short amount of time, so if your phone reaches 100 before you wake up chances are it's been idling without charge for a little.

If the light is green, it's at 100%. mine stays at 99% for quite a while when charging and then eventually tips over to 100%

It might be something about the way that the phone charges. I remember reading that while it's plugged in, the Lumia 900 at least will charge to 100%, drain to about 98% or so and then charge back to 100%. It repeats the cycle over and over as long as it's plugged in. I believe this is done to help extend the lifetime of the battery since it's nonremovable. I'm not sure if HTC does the same thing but that could be it.

I remember that back at launch, people complained about their Lumia 900 not showing 100% when first unplugged after a full charge. I think Nokia addressed the complaints by making the battery meter show 100% up until the phone discharges to about 95%. Not really a fix but it made people feel better about it.
