I've had my S7 (SM-G930W8) since Jan of last year so it's just passed the warranty period and my battery lasts less than 6-7 hours. It'll literally drop from 50-60% down to 5% in 10 minutes. I'll literally have it in my pocket, take it out to check the time or something and it'll be at 50%, then a few minutes later check it again and it's down to 5%.
I don't keep it plugged in after its finished charging, I use the original charger with a new USB cable. I close apps after I'm done using them. I keep Bluetooth/Nfc off and use only 4G.
I'm pretty sure the battery is dying but on the off chance it's not I thought I'd post here to see if there's some other solution. A couple weeks ago I even let the battery discharge a couple times until it shut off and turned it back on after it hit 100%

Have you tried battery recalibration? Also just order a battery off of eBay for 15 or 20 bucks n throw it in yourself. No big deal. Just don't mess with your screen, they aren't very tough.

Yes as I stated in the original post, I let my phone discharge until it shut itself off and then charged it to 100%, which is how you recalibrate the battery. This has had no effect and the battery will still drop in a very short time.
I also have a cracked screen so replacing the battery would be a difficult task to accomplish without further cracking the screen. Not to mention those $15 batteries on eBay or even Amazon are likely knockoffs and will cause even more problems.

Okay...?
The majority of the people here have rooted.
It won't help. I have deleted the batterystats on mine phone more than 20 times in the last 3 days and there is no change nor hope!
Let me rephrase by saying your ROOTED phones battery stats might be lying to you.
And for the guy who tried it three times and failed. I don't think you took the time for fully discharging the phone. That's right I'm calling BS.
Anyway got to go my battery just dropped 30%
Just wanted to let you guys know that this is completely true in my case. The other night around 2am I went to sleep with the battery around 68%. When I woke up 4hours later for work my phone was turned off. I then plugged it in and my battery was at 0%.
I was on the perfect storm Rom. I then switched to das bamf. Still happens. Tried bump charging and 0-100 charging and its helped but when I reboot the phone the battery shows about 7% less then where it was.

I think that is thy the stock battery icons don't show an exact %, b/c they haven't been able to make it work right. Don't worry though i believe that the devs will get it before HTC.
Ok my battery was just now at 50%. I restarted and now showing 41%. I don't know what's going on.

As I said, you can charge and discharge all day long, it won't help!
Thank you for reposting this. So sick and tired of people complaining about dropping 10% in a few minutes after a full charge.

I think this is a glitch. It drops like crazy after restart but then stays there until it "catches up" I guess.

So far,I have only rooted my phone, not a custom rom. I either have a crappy battery life, which seems better when I shut 4g down, or there is a glitch on the metering. My .02 worth.
So i've recently been after a bigger battery for my phone and decided to give the "Mbuynow 6400mAh S4 Battery" a go. The battery cost me £6.25 with free 1st class Royal Mail postage straight from the store itself. I will include a link below if you're interested in buying this.

The battery is approx. the size of two standard S4 batteries and weighs around the same. The battery has a nice, matte finish and feels quite sturdy too.
Upon inserting the battery into my S4 I noticed I had around 60% in there already and I instantly put it on charge. I left it to 100% and gave around 3 - 4 hours extra to charge to full capacity. Upon removing the battery seemed to drain quite rapid. Looking at my stats didn't show anything out of the ordinary and thus went along with it. Did a complete drain and charged back up, again battery rapidly drained. After reading the packaging that 5 or more cycles would be needed I carried on using the phone, charging once dead. I'm probably on my 3rd cycle now and did a factory reset to eliminate battery draining apps.
Enough of that, you're probably thinking "WHERE ARE THE STATS". Well I've managed to get my most upto date reading, and my best, which is 20hrs and still with 74% in there. I suppose I just need to give it time or the fact it's a defective battery. I've e-mailed them and they have agreed to send me a replacement so hopefully this will be better. I will give an update on what is to come. This is with partial use, not much. I left it on over night with the sound on mute and screen brightness on full and hardly used throughout the day.
Conclusion
This is something I can't really conclude until testing the replacement battery. Battery seems good but I don't think you're getting as advertised and it's more likely going to be a 4500/5000mAh battery. I mean for £6.25 I suppose what can you expect. Personally, I don't think it's been worth it for the £6 but in my point of view I could have received a defective unit. But for £6, it's a nice spare battery you can take along for rides and might give you a bit more juice compared to the standard 2600mAh. Providing the replacement is better then I maybe able to say it's worth it but £6 for a battery isn't bad at all. Personally, spend your money elsewhere and go for a proper ZeroLemon, Anker or Hyperion battery.

So, looking at the title you would know this is about my Phone's amazing Battery Life.
But NO, it's not my S6, but my Mom's Phone that has put my S6 and every other phone in my household to shame. My mom spends most of her time on youtube, streaming old songs and watching old music videos. She got this phone after my brother used it for 3 years, which I gave him after using it myself for 2 years. It's safe to say that my Mom's phone is now 5 YEARS OLD!!. I often heard my mom bragging about her phone's battery when I walk around with a Powerbank in my Pocket. So I told her not to plug-in her phone for the next 12 hours.and use it as usual. 15 minutes back, she asked me to plug her phone. That's when I remembered what I told her and I realized it's been more than 2 DAYS!!. I just took a few screenshots that speak for themselves. I wonder how long the phone would last if I turn ON the CPU Power Saving Mode. I must say, I am overwhelmed & shocked.
This is a 2013 phone with a 2100mah battery; Xolo Q800 (a small Indian smartphone manufacturer)

You're right, the screenshots do speak for themselves: they show that it's hardly ever used.
They also show high power loss whenever WiFi is actually on, and a steady decline when it's sleeping.
It seems to have been used like... what, 10% of the total time? Less? With that same usage, an S6 would last much longer.

Lolz...anytime I see her, she's on youtube and I am certain those 5 hours were spent well on youtube. S6 cannot and will never stand a chance when similarly used. You can watch youtube for 5 hours straight on a 5Ghz Wifi, but then your battery will NEVER LAST more than 12-14 hours. I know that hurts but lets embrace the fact! May be you can shed some light on how to make our battery last longer?
I still use my S6 and sad as I want to admit it, the batter is not as great. I don't use much of it for Youtube, but I have about more than an hour of video filming of it for a fully charged phone.
Hello Everyone,
Since Zerolemon came out with the 7500 mAh V30 battery case, I've been a believer in...second chances, and new products are my thing. So, I bought a Note 9 512 Gb for the business, and decided to try this sample battery out.
As it turns out, this battery is good. It executes 1.25 charges on average, but I could never really ring out every last drop. The stats speak for themselves.
Day one:
I was on my phone's battery for just short of 15 hours, and 54 minutes on the first day of reviewing, and I admit, I only listen to music and check my servers from this phone. SSH, maybe a little VNC, and mostly Tidal. There's the first 44% down.
Day two:
Just to make it even, I thought another 44% should do for usage, and practically do the exact same thing going to the client, and check the servers, maybe change the playlist, but not much else changed with my usage other than the time screen on. This took a little longer. 23 hours and 41 minutes.
Day three:
Hectic day at the office, and now the poor girl gets her 85% down from just rocking her world. Almost identical, but now it's cumulative in a sense.
In sum:
Bogging down the battery in spurts made the Note 9 last longer, but total gain was three hours by doing it that way. Main drain was continuous, and that lasts much less time. Draining the Note 9, and the battery case, then my Note 9 again took about 75 hours and 15 minutes, give or take.

The verdict:
This thing saves your ass in a long trip, like a Greyhound from Phoenix to say, Seattle, but who's taking the hound anymore, besides me?
This would be righteous if you were out in the wilderness, too, and you didn't want to use the power saver feature which would extend the life quite a bit more. I'm shooting for the power user, not the camping type, but I will test using those parameters if someone wants me to. Just holler back.
I mean, who's to say that we couldn't squeeze out about 300 hours in that mode? I get power outages here in Phoenix every time it rains hard. I don't like when I'm not entertained in the dark.
Zerolemon, you guys put out a pretty awesome case.
I wanna try this 10,000 mAh battery next.
Thank you for the sharing! We'd be appreciated for any concern you have on this battery in future.
I am interested in this battery performance? What SOT are you getting? What do you get for battery time the medium power saver mode?
Any screen shots are appreciated.
It's on Friday and I feel like the first 48 hours it was draining pretty quick. I upgraded from the OnePlus 6t and I certainly feel the slower charge.
Waiting for it to fully discharge and then I'm going to give it a full charge and then I will post my battery stats after seeing how long it lasts.
Full charge before bed last night .. and I drove around a bit today with it plugged in for about 30 minutes. Going to bed now at around 50%. Not going to charge until tomorrow.

I am still trying to figure out if I have a battery drain issue. I am getting the same usage as what I did as my A70. After full charge it says it will last around 22 hours. Usage is the same as with my A70, not sure if that is right.

Standby uses about 1% for every two hours for me with Always On Display. That is always my benchmark even for my last Samsung. There's something using battery wildly if it goes too high after some many hours or even within one hour.
A hint there, try rebooting 3 times in an hour or so. My last Samsung had an issue where normally one reboot would fix the battery drain but it would every now and then require two more to fix the drain.
The battery use stats might help you narrow down to something but if not then you have to factory reset or disable or remove stuff. If its with the rom then it gets more difficult.
If you are seeing the 1% standby for even an hour or two then it should be fine there and the drain is only while the screen is on.
You might also be able to spot certain things the the logcat.
Thank you for your reply. I will try to reboot it. I have done a factory reset but it hasn't helped. I will test it for a few days.
I have 9hours Screen On Time on a pixel experience rom.
AOSP does wonders to this device.

You never know. Funny how much reboots fix things that shouldn't need fixing in the first place
