Android OS battery drain

[Sedana Diatmika]

I'm using Sony Xperia M2 Dual (D2302) for about 2 years. Since the first time I'm using it, the battery seems fine, but until now, the battery is kind of not doing what it should. And then I checked what drained my battery, and found out that Android OS is the most program that is using my battery.
I tried disabling some bloatware and auto-sync (I'm not even using it from a long time ago) but my battery still draining so fast.
Is there any solution for this?
Thanks.

How long does your battery lasts?
