Battery duration very limited

[frankge973]

Unfortunately, especially after upgrading to Lollipop battery Samsung Galaxy Alpha G850F discharged very quickly and not know what to do :

I have:

1 ) disabled as much as possible ( when not in use ) and the BT GPS
2 ) tried to replace the original battery with a 2850mAh of ( so they say ) not original
3 ) tried to disable both S Voice that Google Now they say consume a lot
4 ) Reduced brightness and battery life activation screen in 15 sec .

The term does not arrive in the evening since it from the detachment at 8:30 in the morning, I get up at 17.30 scarce not use it to call , remaining in the wifi network but navigating virtually nothing .

I'm really confused and do not know what to do . If anyone has any advice and can help me or I know that sooner or later will change phone .
Thanks a lot

I had a similar issue and a cache wipe fixed it.

I tried that and the only result that I had is continue loop of phone with all app that terminates unexpetclty.
I'd to reinstall Android and all apps and settings.
Battery duration has not changed.

Strange my alphas battery is great. It's actually a bit better than my note 3 if you can believe it. Smaller screen must have something to do with it but still. I'm impressed with mine.
