Note 3 battery draining fast?

[dig bick]

Hey guys I have my Note 3 for 1 year++ now and I realize the battery is draining fast recently. It is an international variant SM-N9005 and has a kitkat 4.4.2 on it. I don't see any defect on the battery. Once I plug out of the charger with a full charge, my note 3 will go down from 100 to 99 percent in a few minute. I tried charging it full, disabling wifi and let it be for hours without using it. I then realize my phone went from 100 percent to 95 percent in just an hour of inactivity. The battery usage usually say Android OS system use up the most battery, my battery graph is quite steep though. Does anyone encounter this problem? Is there any tricks to fix it?

Firstly, it is rare for a phone to be 100% charged on removing the charger lead. When it does charge it charges up to 100% then trickles down to an actual 96% or so before recomencing charging back to 100%. When you pull the lead, say first thing in a morning the phone may report the actual value a couple of minutes after the lead pull. This is quite normal, but it does look like the phone is losing charge rapidly.

Another thing to consider is that modern Lithium ion batteries don't like to be fully discharged to a point where the phone shuts down, always keep them topped up if you can. If you regularly let your phone run out of charge over a few months the battery will get noticably more inefficient, a new battery is the only cure.

Having said all that above, have you installed a new app that is constantly connecting to the Internet, is always on in the background, keeps the phone awake etc. Even one badly coded app can eat juice rapidly. I find that "Google books" does this to me. Since I like reading from it and have over 60 books in there, I always make sure I kill it from task manager when I've done with it. That makes a noticeable difference. The other battery hog if left running in the back ground is Sygic (a Sat Nav) leave that running, even when plugged in, and the battery goes slowly down rather than up.

Hey thanks for your reply! I think I might not have any apps installed in my phone that will drain the battery down even when it is charging. I do have a bunch of games app. I don't regulary drain my battery to very low charge and I think that is not the reason for me. Anyway, I will try to disable auto synchronization and see whether it does improve my battery life.

My Note 3 is SM-N9008 and it has a kitkat 4.4.2 on it, too.
But as for battery drain, I think it is not bad. Refer to the screenshot as below, please.

That above is superb, I get around 17hours tops on mine, but it is rarely left alone when on, and I never let it run below 30% normally and am always near a charger.
