Hey guys i got a s4 for free a few weeks ago and the battery was having issues so i brought a new battery from Samsung for $50. I guess the phone is $50 now huh, still that's a good price. Anyway i have an improvement in standby time over the old battery that seemed to drain no matter what, but i only get around 2hrs to 3hrs screen on time full brightness with a mix of auto. The phone tends to get warm when its below 40% power. Also using the phone drains it at a fast rate, but standby only 1% per 8mins or so witch is good. Im backing up with twrp and titanium backup, ive tried recalibration, and im about to do a factory reset on this (stock touchwiz)

Battery calibration apps are a placebo.
Anyway, let me tell you a little story:
2 weeks ago I watched a 2 hour movie on my phone. Started from 100% ans towards the end of the movie I was left with about 50% battery.
Screen brightness was around 60%, WiFi was enabled and the mobile reception was 4G.
All things considered I would assume I can get 4 hours SOT, since it took 2 hours to get from 100 to 50.
This is on a custom rom and battery oriented kernel settings.
Also take into account that I was watching a movie, so the CPU was idling most of the time. Doing tasks and switching from one app to another drives the CPU up.
Your screen-on time seems acceptable to me. I have to mention that my battery is one and a half years old, but I always took good care of it (I never let it discharge too much and never left it charge too much, as both of those, over time, can reduce its storage capacity).
Im using Albe95 rom with a custom kernal and the battery is draining slightly less, ive reduced my brightness to 60% and its drained from 100% to 77% in standby and extremely light use in 6hrs (about 4hrs standby drained 6% and 2 hrs of on off use every now and then drained about 17%. I guess im used to my old LG L70 D320n witch could hold up at full brightness forever. Will Cyanogenmod 13 bring much improvement for me?

I don't know. Maybe Optimized CM13 because it has a custom kernel and you can select battery or performance profiles.

You won't miraculously get 5-6 hours SOT even if the battery is new.
Maybe with lowest brightness, WiFi and mobile data off you will.
Underclocking and undevolting might help a little, but I don't see anyway of getting more than 5 hours.

There's a guide in the general section, _Bon_Bon's tweaks.., Something along those lines is the title.
It has a guide on how to increase battery life.
The guide is based on alucard kernel, though.
Alucard kernel is available for any 5.0 and 5.1 roms. But there is no public build for android 6.
Only JDCTeam roms have alucard kernel for android 6. Those roms are Optimized CM13 and AOSP 6.0 rom.

Ok so slowly things have improved but today when it was at 9% (6:30pm charged this morning) it froze up and i pulled the battery. Then it jumped down to 2% at restart! This has happened before (cant remember if it was on stock rom or the note 5 rom im using on it now) from 40% freeze, pull battery, restart, 22%! Any idea why this happens. I talked to samsung about the battery performance and they just wanted me to send the phone too as "its not just the battery" just for more money instead of honering their 3 month ****ty warranty! Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

The freezes might be caused by CPU undervolting, if you did any.
But the battery percentage dropping suddenly is a sign of a bad battery. It might drop 2 or 3% during the boot up, but not 20%.

Samsung say the phone is the problem. Today i got to 40% and it jumped to 30% within 20 mins. Then i pulled the battery and started the phone up, repeating this multiple times to see the battery percentage. It jumped between 24% 15% and 19% up and down each time i pulled battery and restarted (no crashing just to see what happens). Is this enough to tell Samsung ITS NOT MY PHONE.

Apparently they refuse to accept the possibility that they might have sold you a faulty battery, so they blame the phone.
I don't see how the phone might drain the battery from a hardware perspective.
It's possible from a software perspective, but since you changed roms it is unlikely to be software related.
Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

How did you calibrate it?
Battery calibration apps are a placebo. What they do is they delete the batterystats.bin file which, as stated by a Google engineer, has no relation to battery life or the battery display.
Also, that file gets deleted automatically at every reboot by android itself.
What you could do is:
First let your battery fully discharge, until the phone turns off. Then try to turn it back on. If it turns on, proceed to use it until it turns off again. Do this until the phone won't turn on again.
Now the battery is completely empty and you can plug it in to charge. Let it charge to 100% without interruptions.
Take into account that it can take up to 3 hours to fully charge.

Haha done this before to no avail. Will do again but i noticed battery life is generally better if i leave it charging for 10hours after its charged fully. Instead of taking it off when it gets to 100% but i think a long worded and very angry email is about to be sent to the Samsung repair centre
Sent from my LG-D320n using Tapatalk
on my travels around google I've read many times that with lithium batteries you NEVER want to completely discharge or overcharge them. give it 10 minutes extra once fully charged, not more. you're damaging the poles or terminals or something I can't remember fully when at either extreme. all you achieve is a shorter lifespan for your battery.
discharge it until it turns off but never until it can't turn on again. it has a chip in the battery that needs to stay powered too.
Every since the update my battery seems to lose a percent every 5-10 minutes the screen is on.
What gives?? Tried a fresh install and everything.

54% in the last 3 hours. This is noticeably different.
Have you looked into whats draining it? i.e. under battery settings or using better battery stats?

Nothing specific. Just screen for the most part and a little bit of chrome. I deleted messenger, and Facebook. Everytime I turn my screen on...By the time I go to turn it off after whatever activity I notice a percent loss.
My battery life has never been what I would call "good", but after the update it has been even worse. Wifi and location off, no facebook at all and screen at auto brightness. The battery seems to lose about 10% an hour and I'm lucky if I get to see 3 hours of screen on time.
I'm getting roughly 0.6% an hour when idle with 10j
T-Mobile. Best ever was 8h SOT with a few percent left in 10d. I am on 10j now rooted. Battery life seems worse but really it's not. Used to get about an hour screen before drops to 99% but now about 20mins. Just seems to measure battery better. This rundown so far was at work in downtown and I was on 41st floor most of the day. I am home now where my LTE is pegged full blast and I could probably pull down at least 5 more hours of this charge depending what I do.
I know it's not a solution in the sense its not solving whatever software is draining the battery but there are aftermarket battery packs for the v20 already that will make the phone last longer.
Zero Lemon specifically makes an excellent aftermarket battery pack if you don't mind the bulk.
I am waiting for a middle man battery pack that's larger than the factory battery but not as massive as the zerolemon.
Sent from my LG-H918 using XDA-Developers Legacy app
I have a feeling that my battery life is way less than it should be. I have a Zerolemon 10,000 mAh battery. Most days I don't use my phone much during the day, except for playing a game for maybe a total of 1h 30m throughout the day. Latest one I've been playing is Fallout Shelter.
So in a full day, 5:40am to 7:00pm, I'm down to literally 20%. It feels like I have a stock battery.
Anyone else experience the same issue? I'm afraid my battery may be defective.
You should check the overall SOT. You should get around 10 hours of SOT with that battery. Of course, if the game is very demanding, the battery will drain much faster., as both the CPU and GPU will use more power.
Normally it should go down 1 % every 10 minutes of SOT (normal usage like browsing) and about 1% every 3 hours of idle.
Yesterday I got about 25 % life, today so far I'm at 55 %. I have not played the game since day before yesterday. You must be right about the demand of the game. The note 3 seems to have a very demanding chipset. Even my 10,000 mAh battery cannot keep up with its demand.
My stock battery gives me arround 4.30h Sot on wifi almost min brightness. Is it normal or defective ?
Firmware is 4.4.2
I'm starting to think this is normal usage on our phones. Today I managed to figure out part of my crazy battery usage. It has to do with a kernel wakelock. Bluesleep is the culprit, causing the phone to never go into deep sleep. I followed the guide in the description of this video and it has allowed my phone to enter deep sleep. I've also been using Juicedefender to manage WiFi, Mobile Data and Bluetooth. With all of this in mind I managed to keep my battery usage in check since a few days ago.
In the picture below you can see the list on the left, and how long each condition has lasted.

It's normal.
What is this eating my battery. Every time its available , i monitor cpu usage and i find it at 100% .happens every few days. A reboot fixes it temporarily
Here are the stats:
Verizon
9.0.11
Not rooted
I updated yesterday and the battery drain is a crapshow. Fully charged since 9 am, and its 1:30 now and I'm 84%, with a 6 min screen on time.
I literally touched my phone 10ish just to check messages and text a few people.

Install this: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
Then do some proper measurements. With just your explanation we can't do much ...
Install a kernel. I get 10 hrs screen time with radioactive
Not seeing a difference with 9.0.11 on mine over previous versions.
As for suggesting installing a kernel on a non rooted phone :-/
I also have the same problem, when I was in 9.0.7 I was able to get as much as 13hours screen on time in 48 hours or 7 hours in 6 days. Amazing battery life. Updated yesterday and the phone cannot compare. It is draining as much as 10% over night.
I am stock, no root.
Yeah they fcked something up.
Also beta2 has issues with standby drain...
I've seen this on and off. Some nights latent drain is 3%, others it is 13% with almost no app usage monitored.
Maybe cellular draw? Tonight I'm going into airplane mode with WiFi on and see what happens.

Do you have any social media apps? 7 hrs of sot in 6 days without a charge is nuts even that 13 hours of SOT in 48 hrs is impressive. I've been nowhere near those numbers with my 6t

no social media apps whatsoever besides viber and skype (but these do not count as facebook and the others) but even these are battery optimized.
phone is draining a lot now, not sure why. all is the same as before the update.

I agree. 9.011 is definitely draining battery faster than 9.07

Ya it must only be possible to get that good of sot without those apps. Do you use any Google apps, I know that is another battery drainer which decreases maximum sot potential.

Yes, I use a lot of them, maps, Gmail, keep, calendar, etc etc.
Move to beta 2
Last night I let my phone on .11 sit idle for 9 hours in airplane mode with WiFi on. It drained 7 % over this time which is more than I used to see on build .07 with cell service on.
The odd thing is that apps are reporting very low usage (in total less than 1% of the battery overnight) so I need to look deeper. Phone is >95% deep sleep overnight.
Some nights low drain, some nights high, no pattern I have found.

.11 overnight (8 hours) on mine is currently draining around 3% over that period with everything on as normal.
I have experienced the same. But, after having .11 installed over a week now suddenly my SOT has improved to same level I had with .07.
I have read somewhere that since it is software controlled the system has to "learn" the most efficient way to handle, e g the option "Smart battery" (have that always on), and that process should take approx 1 week.
I do not know what's happens when I updated to a newer version. Maybe the system has to "relearn" again? My device is rooted, so I receive the full version on every update (no incremental) - maybe that also have an impact on the battery performance.
I do not say there lays any proof in this "theory", but my battery life is very good again (around 13 hours SOT/48 hours total). So in case you have updated recently, be patient for some extra days.
If I knew about this I would have stayed with 9.0.7. Let's hope they fix this soon.
Rebooted about an hour before going to bed, let phone charge to 100%. Unplugged. 9 hours later it was still at 98%. This was the first reboot in a while. Just a data point; previous night even with cellular off it lost lots more than that.

Suggest you to Wipe Cache from Recovery after a OTA update.
No issues here with .11
First wierd battery issue is when I pull the phone out of the charger for some reason it goes from 100% to 99% in 10 min of standby. Maybe the battery is calibrated wrong, Idk.
Second. When I watch youtube on the lowest brightness, and not cropped it uses 1% every 7 min, Where as with my Samsung J5 2017 which has a 3000 mah battery it uses 1% every 12 min.
This really confuses me as that the s10+ has not only a bigger battery, but a more power efficient 8 nm cpu.
Are there any known apps that suck battery on the s10+, since I can't get Gsam battery manager to work.

Facebook, facebook messenger and snapchat is the wors apps from my experience.
But download Cpu Spy and see if u get deep sleep in idle as you should, and if your cpu behaves as it should while watching youtube.
-the cpu frequency while watching youtube should not be high at all.
on my Snapdragon version of the s10 plus, my battery lasts between 8-10 hours however for some reason I too seem to get significant drainage from 100% to 90. The first 10 percent drain significantly. I lost 10 percent within 30 minutes and the first 5% within like 10 so aside from that the rest of the battery life 8 to 10 hours that window isn't bad but if there's anything I can do to reduce the first 10 from draining as fast it would be nice if anyone had any advice.
I don't have Instagram or Facebook installed or SnapChat I have Frost and an alternate version of Instagram that's all AMOLED. I hope that helps

Wifi or mobile data?
What's the issue with gsam? I'm using it fine on snapdragon after granting permission via one adb command line.
Drop from 100 to 90 is relatively normally. Been like that on all my recent Samsung devices note 8, note 9 and this s10+.
