hello bro, yes bro. network signal coverage, background system services nu use agitu thaan irukumnga. also notifications services. battery charging practice mattum follow pannikonga. it will help to reach that 2.5 to 3 years maximum mark to reach 80% BH.
Also 5 months usage ku 2% reduce is normal. dont worry
