Earlier model of Xperia SP has bad battery?

[tanmaysingh]

are u guys sure u r getting cmplete day's usage with 3g/wifi/mobile data?.
What is ur month of import mentioned on the packing ?
mine is june 2013 and doubt its a faulty handset.
I take it out of charge at 4 am and phone sleeps till 8 am.Battery sometimes falls down by 10-15% .Is it normal?
HArdly play games,Keep mobile data off whole day till 7 pm with very little whats app and a max of ten mins net browsing.
When i get back , by 8 pm battery goes to 40%-35% .Is it normal?
Also do u have a problem where sometimes the stamina mode stops working and shows u the same time remaining? unless and until u clear the cache from the ECO MODE CONTROLLER APP?Cuz the same happens to me almost every 40 hrz.
P.S.I have Stamina mode activated all times without any exceptions.
So guys is my piece okay> or i believe its a faulty one due to its month of import?

Cause i heard some guys telling their SP lasts two days with moderate usage,And one full day with heavy usage,I never do heavy usage.

Playing subway Surfer for ten mins drains battery by 5% and 7 mins of google Chrome in GSM only mode over mobile data makes it drain by 5%

If you have 4.3 version. 205 it is normal. I have up and down same numbers. The phones battery life is decreased in .205 version.

 have the base version 4.1.2 and have not updated it yet.Is it normal?

I have stamina mode turned on with whats app added to whitelist and I always set network mode to GSM only.

I feel battery is draining faster.Do you have any idea that earlier models were faulty? coz mine was june 2013 import, bought  in june 2014.

Please some body answer this question , i need to know if this is normal or i need to get the handset replaced? as some users are telling they get two days with moderate usage and one complete day with heavy usage?

Am using San Disk microsd card class 4 ,8GB, will upgrade sooon.

Am always on GSM only mode .

I get 4-5 days uptime with moderate use (a few texts and calls, some walkman use and light web browsing). Overnight when sleeping battery loses about 2% or 3%.

Got the same on 4.1.2 as well, so if users are feeling that the battery drainis increased with 4.3 then I'm not experiencing the same.
