I have upgraded my phone (samsung galaxy s3 4G) to android 4.3. it is official upgrade. But after doing so, the battery of my phone drains so easily, and even it couldn't be charged to 100%.
Hello moges. I'm sorry that a problem has brought you to Android Forums. We do have a discussion area for your S3 you will want to check out. Here is a link: Samsung Galaxy S3 4G LTE (International) - Android Forums
Often a major upgrade will not settle in as it should and a factory reset is the fix. I know it's a hassle but you will be happy once it's behind you. I invite you to explore all options before going through that hassle. Perhaps the good members can help you resolve your battery drain problems. Thanks for joining and I hope you enjoy your time here.
