Odd Battery Draining

[IstiaqRony]

After charging 100% of my Xperia M2 dual..
When I detach the charging cable from my phone, the battery came to 98% or sometimes 97% within a minute, without any kind of using!!
but after 98% / 97%, then the battery percentage stable at normal..

is this normal for all xperia phones or this is my battery problem?
N.B. - [my phone is almost new!!]

Settings > power management > battery > what have been using up your battery ? 

[IstiaqRony]

no..
i checked..
everything is okay..
but why decrease 2/3% charge in just one minute only after completing full charge..?without any using?
After then everything is Ok.. 😕

Whenever it reach 100% restart your phone, most likely its not 100%, how old is your phone, 2 years?

My phone has the same behaviour, but I down't worry about it since the battery life is great.

@uliwooly

no...i told my phone is almost new..
2/3 months old...

when I restart my phone, it seems less battery percentage than before... almost 2% from before I restarted..

Yeah.. battery life is great but most of the Xperia users face this problem..

but can anyone tell me, what's the reason of this problem?

You need to leave it charging for another 15mins once it reaches 100% it's perfectly normal
