Wtf? My battery dropped 50% in a matter of minutes.

[Aryeo]

I woke up, my phone was at 100% charge. I turned it on to check email/facebook, etc and suddenly noticed that the battery had dropped to 50%. The battery breakdown menu shows that it dropped almost instantly, 82% thanks to my screen which was at the lowest brightness setting. It's a Galaxy S3.

​

Can anyone explain why this might have happened or how to prevent it in the future? Thanks!

All I can say is that the battery may have been giving a false reading when it said it was 100%.
My old phone (razr i) would sometimes jump to 100% when I plugged it in to charge, therefore it would not charge as it thought it was full. It would then jump down to its actual battery level.
Hope this helps

check your charger. My Galaxy Tab 2 7.0 was having similar issues and it ended up being due to the charger being defective. Other than that, it might be the battery.

Hmm thanks to you both for your answers. I'll check the charging cable/charger and just see if it happens again.

If nothing works try a factory data reset as most of the time it takes care of bugs.
