Can someone tell me if the S3 charges until fully charged then stops? This is my issue. I usually charge my phone over night, a few times when I've taken it off charge in the morning the meter says 100% but within minutes of my using it the meter says 85% (or similar). The battery then discharges at the expected rate over the rest of the day so after 12 hours it might be at 50%. Is this because the phone hits full charge at say 2am then doesn't charge anymore so when I check in the morning it appears to be 100% when I take it off charge until the battery charge app reassesses the level? Any ideas? I've got a Galaxy S3 on Jellybean 4.1.2 Thanks.
