Explanation needed - stamina

[Akkush]

Hi !

Yes i know ,there are many threads with this... But please somebody explain me why is this ?

See pictures.

The facts:

Stamina ALWAYS ON.

Almost NO-WIFI/DATA

GSM Only.

Stock ROM. (No root,closed BL,never touched them because of warranty)

No third party apps. Nothing ,only Stock stuffs.

The nearly horizontal lines means when stamina turned on by ITSELF !

Flight/SAFE-Mode suffers from this too.

All the other times the battery drains ~1-1.5%/hrs.

When Stamina works ,sometimes a call ,an sms or anything disrupts it ,sometimes not.

And finally after many hours automatically TURNS OFF although it's swith is ON !

Service center said : everything fine ,no faulty parts. Nothing.

Tried to repair with PC Companion ,SUS,restore factory defaults ,etc. No effect. Still the same.

~3 month ago i brought home my phone from the SC with an updated FW. Maybe they broke my phone ? Because from that point Stamina doesnt work.... Is it possible ?

Summa summarum : what can i do now ???

And now ,the pics :

Why did you buy a smartphone if you don't use it's features?

Just use the phone as possible as u can. Then you will not have any complaints. Could you live 5 days without eating and drinking?. Same in case of a phone. It doesnt matter u used or not Ur phone. It still needs energy for searching signals. Keep the operating system on. Run the necessary background processes etc. These all background processes allows you to acces the full phone fuctionality when you presses the lock button any time.

After 3 weeks of "tesing" : with or without Stamina... No difference ! 4 ,max. 5 days of standby time without usage !

People form other forums talks about 3-400 hr. uptime ! (with 4.1.2 i had it too)

Phone configured to "offline" usage ,just like an old Nokia 3310.

Battery still drops 1-1.5 %/hr.

Any idea ?

This JB4.3 is a pile of s**t. From its base.
