I thought with the last few eu updates the battery was draining quicker and blamed the Rom for it.
In the beginning when i used the phone I had a SOT average of 6 hours which is fine.
But now I barely get 4.30 hours.....
I use accubattery and saw the capacity decreasing. Lots of people says accubattery is nonsense app. But as you can see it's damn accurate.
I used a usb charge tool and drained the battery once till 0 and let it charge with a 1A charger. The outcome was rather shocking to me....
My battery after 4 months is just 2.699mah!!
A decrease percentage of 20%
I will look if it falls under warranty.
If you have a usb tester please post your results and for how long you have it.

Wow, that sounds bad, a hardware issue. I would use the warranty if possible
I don't use quickcharge (since the phone is heating up way too much) + I use battery charge limit in order to release additional stress on the battery.
Maybe it helps, I will report back whether or not I have the same issue in x months. Cheers!
How long and often did you charge the phone to? Which charger did you use?

Most of the charges were around 20% and 80% but also full battery. And once a day.
I charged most of the time with the 27Watt quickcharger. I guess that's the issue.... Or just a bad battery.
This is really concerning for me. I just ordered my global version and waiting for order confirmation. My main reluctancy in getting this phone is battery life. I am currently using the OnePlus 6t and can average 5-6 hours of SOT. And I need this type of usage for work. This has me thinking if I should cancel or just hope for the best. My only other option at this price point would be the standard op 7.

I understand your concern.....
Please bear in mind that in our Telegram group most MI9 owners does not have the issue after four months. And are rated between the original battery capacity.
My only advice now don't use 27w charger only when needed.... Because device gets quite hot when charging.
Overall I still love the device.
Just imagine when the 100 watt charger is released.

I dont have any battery problems with my 2 months old mi 9, my battery is day and half in full use of phone and i can say that battery is very good on this phone, i cant believe how much negative complains about battery life in every forum.
My mi 9 is Global version with 64gb and i use quick charger and i have one sim card in use, always on display is turned off, fingerprint icon flashing on locked screen is off that is all.
Try XiaomiADB to uninstall all xiaomi apps and apps you dont use at all and and use Youtube Vanced much better than stock app, i dont have xiaomi acount and i think that all apps from them are draining battery.
hi, here's my experience.
My mi9 it's 1 week old, never passed 4h30min of screen time.
No facebook active, only instagram and whatsapp. Gps always on, black theme.
Rom stock 10.2.26.0
Mine in less than 2 months is slightly < 3000 mAh. I've stressed the phone with some bad charging cycles, but with regular 10watts and 18 watts chargers. I will track it in the following cycles to see how it goes. As of me, this degradation shouldn't happen this soon.
To be honest my one seems to get worse from day to day too - I can make it barely through one day now - sometimes I have to charge it two times a day.
I'm wireless charging for the last 3 months on the 27w pad every night. Phone has great battery life and on average use I have about 20-30% left at the end of the day
Same for me, my phone is 3 months old and the battery healt is around 88% for accubattery, I tryed a manual benchmark and the result doesn't change, from 1% to 100% it drains around 3000 mah, in an other forum a guy have the same issue, the battery life is normal, from 80% to 35% from 7am to 19 pm always in 4g plus, whatsapp, some web search, mail and some music, some photo, video, some app download and 30/45 min calls, always using 18w stock charger, getting always around a 3h SOT.
I'm afraid not much better for me either... new device. Only a week old. I left it on stock rom (forced to wait a week to root it anyway...) and I was getting from 100% to 30% during my normal day with fairly light use. My last phone, a Mate 20 Pro, was doing the same with 75% battery left.
Safe to say, you need to take chargers around with you if you want to use it heavily!!

I only used 25% battery today as that was from 9am to 9pm so.... Is so weird you guys are getting such bad battery life..
And I also been trying accubattery for the last 2 days and it says that my battery capacity is 2,923 but I don't really mind since I always end my days with plenty of battery left.
Anyone knows if the use of the 20w Wireless charger damage the battery more than the 18w charger from the box?

When you say it dies fast, how fast and how much display on time do you get?
I'm getting around 5 hours screen on time, but only 10 hours between charging. But the 5 hours screen on is allot, it means I'm playing with my new phone allot and when I settle down after a few days I should be getting real good battery life

Yes, they do that because Samsung feels although it pro longs your battery long term life. My infuse is the same way.
I too am a little worried about the battery life. I unplugged my phone at 5:47 this morning. By 7:15 I was down to 87%. Granted I did read a book on my phone for 13 minutes this morning but still a little dissapointed with the battery life so far. I have had my phone plugged in for 12 minutes and it has gone from 87% to 89%.
I have also experienced the slow charging. It seems to go faster if I am plugged in to the wall as opposed to the USB on my computer though.
i havent tested throughly, but i think it seems to go faster plugged into a wall outlet also.
i wonder if USB is a trickle charge, while wall wart would be a full charge..
is there anyway to see the charge stats from inside the phone? like see how much juice is being shoved back into the battery while charging different methods? an app or maybe some shell command?
If you want your new SGS2 to charge quickly when plugged into your computer, get one of these:
http://mobile.brando.com/brando-workshop-usb-to-micro-usb-cable_p04980c0704d003.html
Has a switch that will put your phone into fast charge mode, which will charge your new phone at the same speed as using a wall charger.
just curious - isn't slower charging better for the battery, anyway?

Yes. The slower you charge the battery, the less capacity it loses per charge cycle.
However the Infuse has a charging flaw in which CPU and screen power usage count against charge current limit, so if the phone is in use it'll charge MUCH slower. I never got any good data from Captivate/I9000 owners on whether this applied to their devices too. Anecdotal evidence is that the Infuse charged much more slowly than these for whatever reason.

By design. USB ports can only deliver 500 mA, so Samsung limits charge current to 475 on USB. Wall charger on the Infuse was 600 mA stock and I had mods in my Infuse kernel series that would bump that to 800 when the battery was below 4.0 volts, not sure about our device, haven't had enough time to read through the battery drivers yet.
Due to the issue I mention above where CPU/screen/etc current usage counts against the current limit, the difference between 475 and 600 was a lot more than 22% or so in terms of current into the battery.
Are the extended batteries popping out the bump at the back of handset. IF that is the case the whole slim sleek looks of SG2 is lost.

Do you want a slim phone or lots of battery time? While we'd like to have both, it's impossible to do with the current battery technology. Personally, I wouldn't mind giving up a little bit of slimness for 4-500 mA more.
I'm not having the problems others seem to be having with the battery. Mine seems to be better than average and is a LOT better than my Cappy ever was.

USB ports in computers draw far less power than what a wall charger would get.
As Entropy said, trickle charge by design.
Getting 2 hours of screen time isn't good, though. It's possibly a faulty battery.. I'd give it a week of normal charge/discharge cycles to see if it works better or not.
FWIW - My heavily modded Cappy got no more than 4 hours of moderate to heavy use on a charge, making me a user of multiple batteries. My totally stock SGS2 lasts from 5:30 am until at least 10:00 pm with the same usage. I don't know why. The Cappy was not OC/UV, just rooted and running a variety of ROMs, but even when stock the battery wasn't good.
Also, the trickle charge from a usb port will take a lot longer (at least 2x) to recharge the phone than any wall charger or car charger. I had chargers all over my house for the Cappy (still do, just don't need them now) so I always had one close by. They're cheap, and beat being frustrated by not having enough power to read a good book or watch cute cats.
I hear slow charge is better too so i bought a cheap motorola wall charger a while back thats output is 550ma compared to the sgs2's charger 700ma. It works great with this phone.
If you are getting horrible battery life try either freezing media hub, factory reset or flashing cognition after i did this i dont have a problem anymore. I dont know which one fixed it but one of em did.

That's not a real Amaze Battery... look at the posting info, it's only 3.7V. the Amaze comes with a 3.8V battery. Just use your old Anker sensation battery. it's the same thing.
I would really like to know if its worth getting since the stock battery is anorexic... and how would 3.7 volts affect the phone. Can it break it?
The phone will be undervolted which isn't bad seeing as how many kernels offer undervoltage

I email Anker and asked them about the voltage difference...
Hello, I have a quick question about the battery for the HTC Amaze 4G.
The OEM battery from HTC is listed as 3.8 volts, but your battery is listed as 3.7. Is there a reason why your battery has a lower voltage?
Could this affect the operation of my phone?

Their response was...
Thank you for contacting us.
I just heard back from our tech team that there is no actual performance difference between 3.7v and 3.8 v and it will not affect the performance of the battery.
Please do not worry about it.
Please let us know if there is anything else we may help. Any time you need us, we are always here.

I don't have a problem with that response. Since all of the components in the phone run at either 3.3v or 1.7v, that .1 of volt should have no affect on the operation of the phone.
If for some reason it does, just return it. They are reputable and have been selling for awhile.
It's not like they are selling these out of the back of a van.
Off Anker topic... But if it's a 3.8v 1730mAH battery, then it's the exact same as the Evo 3D isn't it?
Anker battery
http://www.amazon.com/gp/product/B005M19IZU
I bought the anker battery and charger from Amazon and in all honesty the battery seems to work much better than the OEM one provided by HTC. 1800mAh and seems to provide a good backup battery. The external charger is a neat touch since one does not have to charge the batteries through the one all the time.
I just purchased two Anker batteries with a charger combo for $12.
Here's the link:
http://amzn.com/B005M19IZU
At first I thought that it sounded too good to be true but for $12 it's worth the risk.
It arrived today and at first glance I had a bit of buyers remorse because the charger didn't have any instructions and the charging pins seemed to move around too freely. It just felt cheap overall. The two batteries that it came with say that they are for the EVO 3D 4G as 3.7v and 1800mAh. Yet I let the batteries charge and I daringly put it in my phone. Voila! Powered right up and works just as well as the OEM battery. I haven't drained it yet so I have no idea on how long the battery will last. My expectations? 180 mAh 3.7v battery vs the 1730mAh 3.8v OEM battery... I'm not expecting too much difference to be honest. I'll keep you all posted with an edit in say about 48 hours.
A premature opinion if you ask for it... is it a viable solution for a primary battery? I wouldn't think so.
Is it a viable solution as a backup since we can't charge via 5.0.2.6 recovery? You're damn right!
Another note:
Not sure if it's related to the battery or not but I've had two random reboots with this battery installed. So... perhaps if someone else has experienced something similiar there just might be an issue there. Time will tell.
I bought from mugen the evo3D 1950mah I'm on my second cycle so far not impressed so far at all. The difference between the stock battery and this one is only 200 mah but it almost seems like the 3D battery drains faster

Damn!!!! I bought for 17 two weeks ago!!!!
Just got my Amaze last night. I put my Anker battery that I bought 2 weeks ago for my sensation in it. Unplugged the phone at 9:45 AM, and when I got home at around 8:00 i had something like 15-20% charge remaining. That was after using my phone through out the day to place a few phone calls, constantly checking texts and facebook, and also doing some ebay browsing looking for accessories for it. Must say, I LOVE my Anker battery.
Solid opinions?
I'm planning on buying one (1900mAh). I heard that initial it appears to lose it charge then slows down but still offering good battery life. However I'm a bit unsure.
By how much more hours will this thing pack compare to stock?
Also I hope (and it probably will) increase battery life once we see Cyanogenmod and better kernels. First we have to get through S-Off.
I got the 1950 today is my third cycle, in my previous post it was my second and I said it was terrible, after the 3rd cycle I've seen a big improvement. 12 hours and 12 mins off charger. I started at 100 percent. Right as I went into work. For 8 and 1/2 hours I had airplane mode on, being that WiFi calling doesn't work, had WiFi turned on, and listened to Pandora the whole time.

Just bought this battery for mine. It does not seem to get a full charge. Charging on device only get up to 94 % or so. Any one else have that problem?
edit: meant to reply to Binary. I've got this same battery kit: http://amzn.com/B005M19IZU
I've had this same kit for a few weeks. I have the same complaints about the charger pins but whatever, your hands will learn how to do it quickly after a couple times. Now I just rotate the batteries about every day and a half. On the first few charges I was barely getting more than the stock battery. After a few times of fully charging and fully draining I get about 25hrs of normal use. Last weekend I got 36 hours before the battery finally died.
My usage patterns:
1+ hr internet radio morning commute.
Mail, Facebook, weather, syncing all day.
Random web
random games
1+ hr internet radio evening commute.
not plugged in all night, sometimes I leave sync on, sometimes I turn it off.
1+ hr internet radio for morning commute
change battery some time between getting to work and lunch.
Worth it IMO.
So you are not charging in device though at all. Just their charger?

I bought the single 1900mAh and I can charge to 100% through the phone, it does however discharge down quickly initially. Its slows down after 80 - 90% so the overall life is still good. This is its second charge so I'm still waiting to see if I get a boost.
are you charging yours in the phone or the anker charger? Seems with indicator being off been tryib to charge in the phone myself.
What is thr best most accurate way of charging for life and indicator to be right?

Do you notice the difference in the 2? Like does the qcell with 300mah more make a difference?
I have one; started using it yesterday. Haven't used it enough to notice a difference, but personally I doubt there is one. If it was so easy to fit 300mah (>10%!) extra capacity into a battery, why wouldn't Samsung have done it in the first place? Surely a 2800mah battery would be a better selling point than 2500mah.
I miss that battery testing web site where the guy stress-tested all the aftermarket batteries and showed how basically all of them were massively over-rated.
I have two OEM batteries (got one as part of the awesome Samsung portable battery charger) and I figured for $15 or so the Q-cell was worth trying. One of these days I'll do a run-down test and see if there's a difference. If there is, I'll buy 10 of them and then report back here how great they are.
I *love* this product:

It doesn't charge the phone, but you can toss it in a bag, swap batteries mid-day and have enough juice to get through a long evening of speed tests and server management while out on the town.
I've never had a phone die on me mid day.
I've never had hypothermia. Doesn't mean I don't carry a jacket when it's cold out.
My point is that for me, by mid-day my Note is often in the 30-40% range, and if I want to comfortably go for 8-10 more hours it's nice to have a fresh battery so you don't have to think twice about it. It's one thing to be at 5% and getting critical battery warnings at 10pm when you're home on the sofa. It's another to be getting 5% battery warnings when you're out somewhere far from a charger and need to use the phone.

Mid day its that low? I go through my whole day and by the time I go to bed at 12 its at 40-60%.
Yes. I have 3 email accounts - 1 exchange and 2 IMAP (even though I set the intervals for IMAP to 1 and 2 hours), and I use the phone as a desktop replacement for answering emails, server management, and various other web-intensive functions. I lose 10-20% per hour while in use. Screen on auto brightness. Bluetooth is always on because I use a headset or a car link for voice calls, though I don't make a lot of voice calls. If I did my battery would be dead by noon every day. On voice calls my battery graph drops precipitously.
I am in a fringe LTE area, which I suspect doesn't help. Sometimes I get 1-2 bars of LTE, and most of the time I get 4 bars of non-LTE. Searching for signal and switching back and forth is probably not good for battery. Either that it's the time that it's on LTE that kills it. So I'm resigned to either swapping batteries mid-day or leaving the phone on a charger at various times throughout the day.
Back to the Q-cell battery, tomorrow I will use my other phone for the day and try to run a couple of video loop tests with the Q-cell battery and the OEM battery and see how long each lasts.
Thanks looking forward to the results.

I don't know if running maps in the background or maybe GPS status would help too. Open to suggestions.

Don't they make apps that will drain the battery in a consistent way for comparison?
Actually here are some:

Thanks...I'll look into those but I figure full brightness video is fine too.
Sent from my Samsung Galaxy Note
Test 1 is currently running. Fully charged Qcell 2800, started at 6:45am; as of approx. 9am (2h 12m of full screen video with GPS status running in the background) battery was 65%. I have the phone in flight mode to remove network connectivity/signal strength as a variable. Full results will be in tonight.
Well this isn't even close. I'm half tempted not to bother finishing the test. On test #2, OEM battery, after 2h 12m of video the OEM battery is at 78%. 78% vs 65%....that is HUGE. The OEM is winning by a mile. But for kicks I'll finish the test and post all the results/graphs.
"2800mAh" battery is more like 1600mAh
The results are much worse than I expected. And I notice that Amazon isn't even selling these batteries anymore, so that's something to take note of. I would imagine the data below would look familiar for any aftermarket battery sold at a cheap price (and possibly some sold for a not-cheap price).
Each battery was charged to 100% to start. I used the Samsung video player on full brightness (using the video player setting, not just the Android setting since the video player setting overrides the system). I played 3 movies on the Note during the rundown tests, in the same order. Mostly the Note sat on a corner of my desk playing with volume off; occasionally I stopped it to take a measurement or screenshot.
The "2800" battery lasted 5h 32m to 1% charge. Discharge rate was fairly linear, though it did accelerate a bit starting at about 25%. After movie 1 (2h 12m) it was at 65%, after movie 2 (4h 15m cumulative) it was 30%, and did not make it through movie #3.
The OEM battery lasted 9h 35m to 1% charge. Discharge rate was also linear and remained essentially the same from 100 to 0. After movie 1 (2h 12m) it was 78%, after movie 2 (4h 15m) it was 57%, after movie 3 (6h cumulative) it was 36% (the "2800" battery died during movie 3), and after movie 3 I went back and played movie 1 again (in full) and then started movie 1 AGAIN and got another ~90 minutes into it.
The difference is ridiculous. Since the "2800" battery was only $14, price per mAh is actually better than the OEM battery which is more than twice as expensive, but this thing is more like 1600mAh than 2800mAh. This isn't surprising to me, but it is good to quantify how terrible these knockoff batteries are. If I'd paid $20 or more for it I'd be angry, but given how cheap it was I'll toss it in the drawer and know I have a cheap 5-hour battery in addition to my two OEM batteries.
Since the "2800" battery has only had a couple of charge cycles, I will try to run the test again in a few days and see if more charge/discharge cycles make a difference. My OEM batteries haven't had many more, though, since I have two and I've been swapping between them on alternate days. I don't expect to gain 1200mAh.
Notice something else. When I rebooted for the 2nd test, bluetooth turned itself back on despite the Note staying in flight mode. I didn't notice that during the test, but that means that the OEM battery was actually under more load than the "2800" battery for the 9+ hour run.
tl; dr:

Damn.
I have been hearing that the Hyperion ones are good, though. The pricing seems to be about the same as the QCell. I guess I'll find out--they should be arriving today.

please report back !
So after using them for a few days, they actually seem pretty good.
I don't think I have the patience that Hausman (I actually want to call him 'haus) to do a more technical burn analysis (thanks 'Haus). Plus, I'm lazy. However, I've been using them instead of the Samsung OEM battery for the past few days and they seem to be transparent enough that I don't notice that a different battery is being used.
For $30 on Amazon, I'd tap that.

reflash the RUU at 100% battery, and see if you still have problems
I'd rather get a powerskin with an external battery that I can choose to use or not(or remove)... but the powerskin won't be as efficient as you need to convert from 4.2V->5V(USB) back to 4.2V

How I am using my phone is like this, pick up off charger phone has full charge, go to work, listen to music from phone, once I arrive at work I put it into airplane mode (this I believe kill's all the radio's ) then use the phone as an mp3 player every once and a while waking up the screen to pause etc. the battery is the original that came with the phone I got this phone like on the 2nd day it was available from T mobile. I am sure the battery by now should be suffering from constant use. I have the full version of juice defender and I have that killing everything I can think of to save power.
I can't remember the name of the ics rom I have on it now but I did install the new graphics driver as well. the phone is rooted ,s-off and has super cid.
I am waiting for a newer stable ics rom with jellybean hopefully with a kernel that I can play around with under clocking.
With my current financial situation i can't afford to make a mistake on this purchase so I am being extra paranoid about checking all my options, thank you for your suggestion.
Haven't used that particular battery, but used mugen with g2 and didn't notice much of a difference. It was 1800 instead of 1200

hello mate! i would suggest getting rid of sense as much as possible there are about at least 3 senseless roms out there,or at least the launcher, it uses to much resource with all the pretty animations and widgets! but there is something wrong with you phone somehow, i get up in the morning around 8 and go to work with my phone fully charged, listen music in the car for about 40 mnts until i get to work! after things settle down i watch at least 3 50 minutes video on netflix, youtube, play listen to music again, i'm on fb, instagram, skype chatting with some friends outside the country, texting and a little more, back to listen to music on my way back home, by 6 o'clock i'm with 30% or so! i'm running energy stock look rom, tweaked with ultrasmooth rosie, and the only widget i have running is the clock and music with 3 home screens! good luck

if you really can, try to reflash the RUU(charge your phone to 100% first).... this resets your phone entirely (radio, ROM, kernel)
I had that battery problem when I got my phone from someone else: less than 8 hours of uptime even without much screen-on use... I installed the Energy ROM and faux kernel, didn't fix it
now, after reflashing RUU, then installing Energy ROM and faux, my battery is better than before... 15 hours uptime with 1-2 hours use...
if I don't use it and keep it on standby-idle, i'm sure it,ll stretch more than 2 days
(55%, only about 15 minutes of screen-on use, data on, autosync on)

I don't understand what flashing the RUU means. I will look around on the forums to learn what that means, or if you would tell me I would appreciate it.

Just buy this http://www.amazon.com/Anker-1900mAh...345472451&sr=1-3&keywords=1900mah+anker+amaze
2 1900 mah batteries with an external charger, charge the spare and your phone every night, put the spare in when the battery dies.. MOST of us have these batteries, they are a little higher capacity than stock- the ONLY issue I have read and experienced, the first 10% goes quickly.. but overall it always outlasts the stock battery.
Plus, that is $30 for those batteries, rather than $100 for the one you posted.
Plus stalk the posts I make, I've posted plenty of ways to increase battery life.. and if you can figure out what paperwastage was saying(hint:look at the bible posted in my signature for EVERYTHING you need to know), it will make a big difference. Plus, if you are in airplane mode while at work and have big drain, that means some app is running rampant in the background, keeping your phone from "deep sleep". Get an app called betterbatterystats(paid on market, free if you find it on XDA, but worth the money) and after a days use(BEFORE you plug in or switch batteries), look at the top apps listed when you select "partial wakelock" and "since unplugged"- whatever the top apps are are the ones keeping your phone awake all the time.. either change the settings of those apps, or remove them if you don't NEED them as that means they are poorly written.
Without getting super technical and by stalking my threads, the bible in my signature, and using betterbatterystats, you MAY not need new batteries anyways.. but having a spare fully charged battery gives you a freedom that you really deserve anyways.
You can buy extended batteries and multiples of them with a charger. You can also buy external battery packs/chargers (amazon search for Anker Astro). They are a bulkier solution but versatile as in they can charge almost anything that takes a usb plug.

First, based on my usage over the past 3 days, I don't know how that would be even remotely possible. Right now, I have all of that turned off, and my battery is dying just sitting there laying dormant....never saw that before, even with something as small as an iphone 4.
Second, I think you actually proved my point when you said you have to use 2 batteries. I've had iphones and an galaxy note 3 and s5 before and it was never an issue before that I even had to think about having a second battery. I used to read reviews of people saying that a benefit of a samsung over and iphone was the removable battery....while it's true that the battery might be removable, with the iphone you don't need to.
You should not exaggerate, sure this is not the phone if you're a really heavy user.
But I'm using it with everything ON, and never had a problem with it, I'm charging it every night.
But if you do have battery issues, you can buy yourself the 2500mah extended battery.
http://blog.gsmarena.com/apple-iphone-6-battery-life-test/
http://blog.gsmarena.com/samsung-galaxy-alpha-exynos-5430-battery-test/
I am a heavy user and average about 4 hours of SOT with LTE Web Browsing and about 30 minutes of calls BUT I will probably get the 2500 Mah Battery ..
Also there may be a 20 -25% difference between Qualcomm and Exynos Versions with Exynos better ( wild guess on my part on %).
Still coming from a Note 3 , Alpha could be a shock.
Should have been 8mm thick with 2700 Mah
Battery and Ram and Camera and SD like Note 4....THEN Alpha would not be discontinued...lol.
I think you have somehow faulty phone, because this phone has awesome standby time, even with nfc/wifi/GPS on. And it can even survive 30mins of talking with just 3% of battery. Usually the battery in my alpha and in some other alphas survives 12+h with wifi/nfc on and with 3-4h SOT.
Sounds like the phone or battery is messed up. Just replaced battery. If it still doesn't fix, contact carrier
Sent from my DROID RAZR M using XDA Free mobile app
I've had my Alpha for a week now (Exynos version) and I'm disappointed in the battery as well. I bought it for music playback and I took a six hour drive over the weekend with it functioning in airplane mode streaming music through the headphone jack. That was it. It was down to 9% at the end of my drive. Call me crazy, but that's unacceptable for it not being connected to ANY network. It was just playing music and an audiobook located on the device. Is this normal? I can return it, but I love the form factor and the audio quality is second to none, so I will probably just live with it.

There is an extended battery that you can get if you need some extra juice.

Yes, I would love to. Please let me know how to do that. I will also try to look it up, but I haven't used android in a while so it's all new to me again.
Incidentally, I continue to be dissatisfied with the battery compared to my past iphones. I have everything turned off, e.g., NFC, bluetooth, etc. And, I hardly have any apps installed.

@ skirush, you either have a bad phone or an app that is draining your battery in the background. And don't blame the "pathetic" battery. I'm getting 70 minutes of screen time when my battery drains to 20%. Also, I am not using the power save modes.
Did you buy your phone new? It is very odd that you are not getting better performance from your Alpha.
I'm not really sure what to do. I'm pretty pissed about this whole thing. I went out on a limb and bought it new online. Once I got the phone, I confirmed with both AT&T and Samsung that the phone was legit and both said yes. In fact, Samsung even said that the phone is covered under warranty. So, instead of returning it (due to the poor battery life) I kept it. Now, I might be too late to return it to the company I bought it from. It's been over their 14 day return policy.
I have had the feeling that its messed up ever since I first got it, but I decided to stick with it since samsung said it was legit. Now, I'm regretting it.
thumbs down for Samsung support
I called Samsung tech support/customer service. Get this, they are willing to replace the battery...IF, I first send them my battery that's currently in my phone. That's just not possible. Like most people, I have one cell phone with one battery. I don't have a landline phone. So, I don't have spare batteries just lying around to use in the mean time.
That's bs from my perspective. I've had replacements on phones sent to me before. For example, ATT sent me a replacement Note 3 and they took my credit card info on file. After I returned the old unit back to them they release a hold in the amount of the phone.
Not sure why samsung is unwilling to do this. Seems ridiculous to expect someone to send them a battery for their phone, thus rendering it useless. And who knows how long it would take them to send a new one back to me. Could be a total 2 weeks without a phone between me mailing them the old battery and them sending me a new one. Who can do that?
a battery costs about 10$ and for longer trips you may need a second one. So why don't you buy an second one and send the battery from the phone to Samsung?

I am an ATT user so I did have the 850A version with the snapdragon and I did notice that the battery life was pretty bad, but not as bad as you illustrate - and yes this phone gets nowhere near the life as the IPhone6 (my wife has one too).

I totally agree with this. The NFC chip on this phone kills the battery. I dropped from 100 to 65 % in 4 hours with the phone in standby. I turned off NFC and 3 hours later it only dropped another 6%

I had a DLNA app in the background running (just the service) and it too drained the battery as it was constantly trying to find DLNA ready devices.
Bottom line: Either you have a defective battery/phone or you have a consumer that you have not discovered yet.
BTW I switched to the 850M with the samsung chip just because I get the rooting support that the A version will propably never get. Plus the phone outright is cheaper.

I purchased this aftermarket battery as a backup. it's been working like the original one. $6 shipped to you is a steal for me. http://www.ebay.com/itm/Replacement-Battery-For-Samsung-Galaxy-Alpha-G850-/111584617173
Sucks that Samsung is making you jump through these hoops. I would check with the retailer you bought it from if you can exchange it. If not, file a claim with your credit card. Good luck
