battery life problems after update

[Sam1105]

Hello Everyone,

after the update with version 14.1.G.2.257  myn lifespan of the battery hasn't improved but got a lot worser.

All the other changes are noticeable and oke but the battery isn't i hope you can fix this problem.

Did you have Stamina Mode enbaled prior to the update? If yes, you will need to re-enable it.

I haven't noticed any significant battery life changes following the update.

honestly ive not noticed anything bad with the battery life. after using an s2 for what seems like forever (3 years) i finally switched to something with a lot better battery.. so basically anything more than 6 hours was great for me im running 18 hours + on a single charge so im happy... i really dont expect a smartphone with all the running apps and data to run more than that...

I can however say that if i turn off data and just use wifi once in a while along with calling (no games) i can get it to last 2 full days.
