During charging, after my SGS2 reported battery full (Battery Level 100%), I unplugged the charger and noticed the Battery Level immediately dropped down to 93%. So I plug the charger in again, keep an eye on it, and when it reached 95%, the indicator immediately jumped to 100% and the phone reported Battery Full. I unplug the charger, and it immediately drops back down to 95%.
Is this a known issue? Unplugging and replugging the charger allows the battery to continue charging, but not an ideal workaround by any stretch...
You need to do a battery recalibration. Drain phone until it switches off by itself, make sure phone is off then charge until 100% before turning on. If you have root, delete the battery stats also before doing the above. Use the Google forum search function for more details
Its standard multiple posts on SGS 1 forum and reasons why .

Has anyone noticed that their 3D drains while it is plugged in? I plug in my phone for charging. It charges completely and the LED turns green. Then it begins a slow drain (as if it weren't plugged in). I notice the behavior on system panel. It shows I have it plugged in, but my charge is slowly going down.
What's going on here? Is this normal?
I read somewhere that once it is fully charged, it stops taking juice till it drops down to 90 percent and draws juice again while still plugged in.
I think this is from the intelligent charging that most new phones have. In fact in every android phone i have had...i put it on charger at night, wake up and it shows full charge, but if i unplug and replug it will drop down to 94ish and start charging again. I believe it is a form of governor to prevent over charging and heating.
Looking at my Battery Monitor Widget information, charging overnight, the battery gets to 100%, then is allowed to drop to about 95%, then charges up to 100%, then drops, then charges, repeating the cycle between 95% to 100% until unplugged. It looks like a saw tooth pattern.

noticed this as well
I love Battery Monitor Widget Pro.
I checked my log file from over night and noticed the same pattern. Goes from 100 to 95 percent. Pretty cool.

seems HTC tweaked it since the EVO 4G, it would drop to 90 not 95. I been using that widget, too, to monitor it.
anyone notice when it starts to cycle back to 100 it stays 99% for a while longer than what would seem normal?
What happens to your phone when you disable it?
I noticed that without this mod, when your battery becomes full it gives out a bleep and then STOPS CHARGING. You will notice in your battery usage graph that it will start mapping out your usage when you receive the notification. What'll normally happen is that when you wake up you'll see a few hours of use already and a little battery drain.
With the mod you don't get the full notification and when you do wake up you will get 100 percent battery upon unplugging the device.
Now is this safe to just let it continue charging even if the battery is full? Should I be concerned about my batteries health?
The mod should have just disabled the notification and the warning tone. When the phone reaches 100% the charging stops and acts like a trickle charger to maintain it at 100%
Yeah but like I said, if you've tried the unmodified VR it charges up to a 100, bleeps the notification and then stops charging at all. That's why when you wake up you're prolly gonna end up at around 93%
It happened to me today like when the battery was about 40%. Then, when I plugged in the charger the battery icon was at half of the icon. So, there was charge left in it. The, I pulled the battery and again reinserted it. Plugged it in. The charging led was red and the icon was blank as if there no charge in it.
Did anyone experience anything like this?
yes
me
my phone is always drops from 40% to 1% with any roms
Hi,
I can't use my phone without plugging it into a charger and socket and when I remove my phone from charging, it turns off itself and I can't open anymore so I decided to buy new battery(im not sure if this is original) since I thought it just a battery problem and now I can use my phone even if it is not plugged into a charger but the problem now is my phone shows more battery % but after several minutes, it turns off and it shows that the battery is at 0% so meaning it drops to 0%.
