Guys new owner here. Switched from iPhone 4 and this phone is awesome. But then anything is awesome compared to iPhone 4, that piece of crap.
Anyway there's one major problem im having tho and I'm hoping the sifus here can help me out. The battery life is horrible. Less than 4 hours and I'm down to less than 20%. I don't play game at all . I use this phone for work and mostly just whatsapp. Maybe there's some tips you can share with me to help with improving the battery life would be great. Thanks.

And the most annoying thing is even when i'm charging the % actually goes down.

The thing is most people reported at least 8 hours of usage and I'm only getting3-4. Either something's is wrong with this new phone I got or there's some settings I can change to help with the battery life. I haven't changed anything about the phone. Everything is stock. No mods or anything like that. I don't even know what they do anyway. I'm totally new to Android. However I've downloaded smart booster per my friend's recommendation but it's not helping at all.

I just found out something new to me though.i have access to different chargers and some charge faster than others, some are so useless that even when I charge the % number actually goes down. Does that have anything to do with the Amp of the charger?

Hardware version H-3-01, Software version S-3-01. Is that what you meant?
