Those with power drain,
disable geo news,
use 3g instead of 4g,
disable gps if not in use,
auto power save and manual light adjustment (try to stay in 15-30% zone),
in playstore deselect auto update, or it might scan all the time.. This is basically the biggest phone wakeup battery drainer.
If rooted you can install one app called shutup google, it fixes doze and removes wakup all the time.
And by packet disabler you can disable some extra bloatware..
Well sometimes there can be a app draining it, it starts to use bigcores and heats phone a lot, I was monitoring cpu/freq. once in Kernel Auditor and then something went rouge in the background., I saw battery drop 1% almost every minute, when I removed some free apps (full of adds), and cleared phone app cache partition it stopped and phone went back to normal.
Actually now that I think about it, you can access this odin mode not rooted,
press volume up+home key+power key while the phone is completely off.
And select clear cache partition, reboot and wait few moments, maybe reboot again after a while, now it should be all ok.
I have this phone 850F since early 2015 and its still good, just shame i didnt buy that 2500mah extended kit when I had the chance.
I bought few custom batteries and the only ok so far is one german Patona 1860mah, no nfc on it though.
IronKing 2100mah looked promising too, first few 5-6months. I got extra 1hr OST, max I ever saw was 6.29hrs on lolipop (unrooted), otherwise I got this on kitkat a lot -6hrs always, then something glitched and its capacity droped to stock 1860 or a little lower..
That said, new stock battery is ok too, mine lasted ~ 15months until it started to drop more, but there are a lot of fakes on the market now.

I'm able to get ~ 5hrs OST with rooted stock rom and extra disabled apps, usually 1hr - 20% or 10% if just browsing using samsung internet 20-30% brightness (basic powersaving on).
This A3 2016 battery is 2300mah and that would be great, extra 1hr OST for sure..
Fast phone, very light and ergonomic, like everything.
BUUUT battery was draining fast until not charge anymore, so I got a replacement battery and still not a good life, recharging twice a day as the previous.
If they do this phone again, with a long-lasting battery it would be killa!
It seems like this year samsung won't make small phones anymore... very dissapointing... I was expecting an a3 2018 with 5.3inch 18.5:9ratio ... but no... I am asking too much from this company.
Today, accidentally, i see my friend using galaxy A3 2016. And A3 2k16's battery is fit for galaxy alpha.
Is there any samsung alpha which has SD card option, may it b Korean American r another, to me its one of the best small size mobile only lacks memory expension.

whao, forget lie and say the fact,my experience about Samsung galaxy alpha is real.The phone is cute and long lasting battery enjoying but I can't get a replaceable battery.
It is so bad that Samsung did not deliver Marshmallow update to this phone. There are still people in warranty devices and not getting updated is just really bad Samsung! This phone was really expensive and by the specifications it has should be updated ASAP.
I am tempted to send it back to Samsung with a coffin like box and with a RIP in the box's face.
Now, if only Lollipop was not buggy... Nice commercial tactic Samsung.
Waste Phone i bought in Chennai for Rs-38000/- with bill.
The batter is worst if put 100% charge and if you use for 30 mins call and 30 minutes browsing the phone charge will be 40%. Phone keeps on Hangs. whole day charge will not stand.
If i would have bought a gold ring for this money at that time, by this time, i would have sold it Rs-40000/- 2000 extra profit i would have earned. Bad words are coming in mouth on this Samsung Galaxy Alpha Model's Performance

If I get back in time, I would still buy this phone. Unfortunately no one had known that this phone will be killed at lollipop. No one. And sub 5 inch phones are getting extremely rare these days. Iphone 8 comes to the rescue.
I've got three words to describe this phone : Completely Wasted Potential !
I cannot even start to express how I liked this phone when I was using it back in the days. Sharp display, small form factor, bright display, bright colors, snappy processing, feels solid, has a very nice look. I got a spare one at home and everytime my current phone was giving up or having some kind of problem, I was gladly using back this phone until the repairs were done or I have a new phone.
But why ? Why did they stop the updates at Android Lollipop ? Why did it have only 2GB of RAM ? And most of all... Why did they put a battery that is so low and a software that is so inefficient at managing battery power ? (I could BARELY last the day with this phone with normal operation... without battery saving)
If it wasn't for these three annoying factors, I think I would've used this phone till it died... unfortunately the battery life alone reminds me why I only used it occasionally. It wasn't acceptable at the time it was released that a smart phone had a battery was dying so fast.
What's questionnable about this phone ? The amount of RAM.
What's enjoyable about this phone ? Everything else except the battery and power efficiency !
What kills this phone ? The battery size and power efficiency.
why no update after lollipop ! This is not reasonable at all samsung !!
i'm not sure people r complaining about the batt-life... i think the battery life is good enough...have 3-4Hrs screen on time and 14hrs stby ..whiches..seems good to me...and this phone still punch all game on playstore xD
g job samsung...
