Hi, I have been having this problem for few months now. I have changed the battery but it is still the same.
Even at idle period, the battery charge is fast enough for 100% to be over within hours. and if I use it, or play some game, it lasts for barely an hour and half.
most of the background processes are turned off and I have already checked by going in safe mode but the battery drain is the same, and even factory reset the mobile.

Model: Samsung note 3 sm 9005

Hello

What app's have you installed lately?
nothing. right now, i have factory reset and have installed only instagram and viber. also, i have recently upgraded my android version to lollipop which was an official update. It was only recently (about a month ago) while the problem of battery draining has lasted for months over half a year now.

Yes, if you go to the threads, you will see that this is a known problem.
Is your model sm n9500 rather than what you posted sm 9500?

Also you can shut down the wifi while idle to prevent battery drain.
yeah the battery drain is still there, I don't know if the battery is the problem now since I did everything listed above. I will try another new battery and see what happens.

Ok,you may want to check your app's,to see if you can determine what is running constantly .
I checked with gsam battery monitor. It is the same. The wifi on has the fastest drain about 1% + battery drain in a minute. I don't know about before but after the factory reset, I have only installed few apps like instagram and the useless apps have all been disabled.

It seems the issue is caused by the lollipop update. Some fixes may work. Clear phones cache partition,factory reset (which you have done). Shut any GPS until needed,If using an AV check the AV and it's use of resources,use Power Saving mode,try to power phone in safe mode to see if you can determine if any app's are causing the issue,syncing in lollipop seems to be an issue,because it's trying to sync with a lot of app's example like email.

EDIT: Also this seems to work , while idle put your phone in airplane mode. BTW in airplane mode your phone is suppose to charge faster.

Is that true of all models?

That model has had battery issues and updating to Lollipop make them worse but they are there before the update. The OP also said
the problem of battery draining has lasted for months over half a year now.
and Lollipop was only installed about a month ago.

Read reviews before you buy any hardware. If something is bad, you'll see posts about problems. I avoid anything where I read lots of complaints from lots of different users.
