Xperia e3 battery issue

[siwy991]

Hello, I have one problem with Xperia E3's battery indicator . Generally battery condition is not a problem and drain by whole night is about 1-2%, but sometimes through the day I can notice a 5-6% drain by a 1 h when it's in sleep. There's no apps in background and battery drain sometimes appears unexpectedly. It can drain a 1% through the night, but it can also drain 5-6% per hour still with no apps in the background. Also I've noticed that my battery sometimes is not full charged, e.g after whole night charging, in the morning I can see 97% or 96% and it's still plugged but not charging.  Yesterday i charged full my battery and turned off for night. Today in the morning I turned on xperia e3 and after while my indicator showed mi 89% of battery, despite it was 100% at turning off last evening. Despite this battery lasted few hours at the same level. What do you think, it's problem with battery or just software issue?

Not too sure what it could but since you are having problems with the battery try this http://talk.sonymobile.com/t5/FAQ/Facing-problems-with-abnormal-battery-and-shutdown/m-p/320375#U320...

You can also boot on safe mode and see if the same issue occur

Unfortunately, it didn't work.
Ad. 1 - trick with power and volume button didn't work in my xperia e3, just nothing happened:)

Ad. 2 - safe mode? unfortunetaly my issue first appeared on clean system without any third-party app.

I also remeber, when I bought this phone 2 weeks ago, I left it all night turned on (in sleep), and it resulted in deacreasing battery from 50% to 0% in the morining without any app even installed. This drain happened once, but sometimes this battery drains unexpectedly as i wrote. On different forum I've found out that some people suffer the same, i'm pretty sure it's a fault. Maybe next update will fix it? If not, should I take an advantage of the guarantee ? Battery is good, but it seems to be problem with problem with charging or indicator, anyway I want this device full charged without any faults.
