after rooting the phone, when i check on my battery usage, it suprised me that the main battery usage is not standby anymore. instead, it says 80% on display, but i didn't use the phone that much today and the battery drops pretty fast. alot worse than before root. anyone know what happens?
I noticed that in the Battery Usage the display is always first with a really great percentage, BUT if you use Spare Parts you will see the normal usage.
So, I think it's just a bug.
My battery is better than before actually!
My battery life is much worse actually, I think i have the 020 root, not sure, as in my phone settings it says FW 020. I thought id downloaded the 023 root though...

My battery seems better but I just noticed something, the little battery graph on top of the phone, there are 5 stages if I remember correctly (5/5 being full and 0/5 being mostly empty). So math wise, under 80% it should display the battery at 3/5 full, mine is at 70% and displays 4/5 full, is sony trying to screw us or did I do something wrong?
I'm using AOKP (4.1.2) and I really love the rom itself, but I got the feeling that my battery is drained more when screen is on than usual.
With screen off I get good battery life - like 0.5 - 1% battery loss per hour with the standard samsung battery.
But when I surf over wifi for like 15 minutes the battery is drained like 10%. (I always use lowest brightness setting)
I know that the screen really eats through the battery, but this still seems rather high, doesn't it?

Welcome to Jelly Bean. :highfive:
That could be it - so far all jellybean roms I tested seemed to drain more power with screen on than ics or gb ever did.
And my problem is not related to no deep sleep or something keeping cpu alive - when screen is off everything feels normal.
I have reverted to rocket rom v12 cause that... JB is nice but this battery leak is not acceptable for me. Rr v12 is best solution definitelly.

What I found out so far: auto-rotate on is a battery drainer - with it on system_server constantly stays at like 5-10% cpu usage, android.system.ui also uses more CPU % with auto-rotate on, CONSTANTLY.
I've read this is due to a too short polling interval for the location sensors, if someone knows how to change that please let me know, but I'm also trying myself.
Use BetterBatteryStats, my friend, to check if there's a wakelock with some app.
battery drain
i am watching this thread, because i also encountered battery drain on JB. thought battery is gone. hence bought a new one. slightly better but still drains a lot. i think the battery drain is because of smart stay. smart stay uses front camera to decide whether you are looking at screen. so when screen is on, front camera is also on and hence the double drain. at least for last four hours, battery drain is in check, after i turned off smart stay. hope this is right and help all of you.
I have the same issue.. Infact I believe this damaged my Battery.. it was working fine until I was on Stock ICS. After I flashed JB LSZ, I noticed heavy battery drain as well as wierd battery status indications..
Just today I noticed that the battery is slightly bulged..
it might just be the wrong time, or something with the ROM..
my phone is just 15 months old now.
Well to be honest my battery life is "ok" - I do get like 1-2 days depending on usage. As I already said, when the phone is in standby mode it drains very few power like it should. (I do have flight mode on almost all the time too, because I don't use it as a phone, just for data when I need it)
But I got this feeling that the battery drains alot faster than I was used to on screen on time since I'm on jellybean. The thing is, that I've checked almost anything, with BetterBatterystats, BatteryMonitor Widget and Powertutor.
The drainers when screen is on are #1 the Screen and #2 Android-System using the CPU. I've already deactivated auto-rotate and the media-scanner, this helped a bit. The only process that's really showing up in System Load is "android.system.ui" at like 2-5% CPU.
Is this jellybean-wide or could this be due to the additional AOKP tweaks?
How can I break it further down to find what really causes the load? (beside Screen taking more energy on JB which would make no sense from a physical viewpoint, the cpu-usage of android.system.ui can only be the other cause of the battery drain right?)
I apologize if this was asked before (I did a search of the forums but nothing really came up), but I'm wondering what others' experience with the battery life of the S4 is? This is my first smart phone and coming from a non-smartphone, I'm not sure if my expectations on battery life are unrealistic.
I got the S4 on 4/29 and brought it through one full charge cycle and several part cycles. Battery life is pretty important to me so I put an all black background (since its AMOLED), keep the brightness to below 10%, turn off all the fancy sensor things, turned on power saver mode, turn off wifi and data unless I really need to use it, turn off all sync so it only happens manually, etc. Yesterday, I charged it to 100% to see how long it would last and the stats I got were:
At 6% battery left, I had a total screen on-time of 2 hours and 58 mins and 1 d 2 hr on battery. Then, when I charged it to 100% and took out the charger, after about 5 minutes of it sleeping/screen off, the battery percentage dropped down to 97% with no data, no wifi, no active apps running.
With my pretty battery-friendly settings on my phone (or at least I think so), is this battery stat normal to others with this phone? Or do you think something might be wrong with the battery?
That sound horrible. There must be some rogue apps running/some wakelocks - try using better battery stats and find out.

For a smartphone, an 'all-day' battery is fine, and given that the S4 has so many sensors, large screen and a powerful processor, I am happy with the battery lasting for 12-16 hours. I don't turn off any sensors, why get an S4 to run it on power saver mode and turn everything off? It defeats the purpose, in my opinion. I am trying to use as many features as possible on my S4. Of course, there are a few I don't, but just for personal preference. What you are doing is (no offence) in my opinion like getting a BMW M3 and running it on 4 pistons to save fuel.
Anyway, your battery life will improve after about 10-15 charge cycles, I noticed that with my past phones as well. If you need your battery to last longer, I would suggest getting a spare battery and keep it charged at all times for any emergencies. These are some of the reasons I love Samsung, removable batteries and microSD card slot.
thanks for the replies guys. I'll try the betterbatterystats app out. i'll probably take it back to sprint and see if they'll replace the battery for me. the screen accounts for about 50% of the battery usage in the stats and other apps take up the rest. the battery curve is pretty linear in a downward slope too (except when i don't use it at night, it becomes much flatter, albeit still downward).
haha its funny you say that, because i agree completely. the m3 is my dream car and if i could ever afford one, i would probably baby the crap out of it the reason why i got the s4 (and i also compared it to the htc one as a possible candidate) is because of the removable battery, sd card, nd most importantly: camera. that 13 megapixel shooter + hdr is really great for good photos on the go. speaking of which, i use the camera alot. is the physical use of the camera and the screen use a big power hog?

This is what I expect from S4
Google Services may be Google Now.....unless you use it, you can turn it off........
The phone only takes 1h 57 minutes to charge from flat. It's mad how fast thing thing charges from AC so battery life isn't really a problem. (yes I was sad enough to time it)

I changed from Note 3 to s 6 edge plus recently
The battery drops 5% per hour overnight when not in use. If I go to bed with less than 40% battery at night I am sure to wake up with my phone switched off in the morning.
When in use with screen on, the battery drips one percent every two minutes. This is the worst battery life I have ever seen in a phone. I was a long loyal customer of samsung and this is my last samsung phone ever.
Extremely disappointed
Please post your battery stats ? so we can have a better understanding of your problem. I suggest you install 'Doze' which should stop unnecessary apps from connecting to the internet and causing your phone to awake from deep sleep.
Dear Akbar 11
Heres the battery stats....is it normal?
I had the same issue, and as far as I managed to find out, it is a bug in Samsung's kernel. Flashing Arter97 kernel solved the issue for, but do post battery stats from SmartManager. If it says 'Android' or 'Android OS', then you have the same problem many of us do.
I don't think it's a kernel problem. My android OS is very low 4%. Like zoolok said post your battery stats from settings, battery, battery usage
I have the same problem. Battery was great before I flash custom rom. After going back to stock I have big battery draining. I must stay on custom rom. With Audax rom and Skyhigh kernel i have great battery life.
You have either messed up something big or you have an app in the background that is eating up your battery like no tomorrow.
And the reason i say that is because i recently got this battery life on my Galaxy S6 edge+.
And this was taken 2 days ago.
Here i use the CRISSCROSS ROM, AudaxPro Kernel, Greeinify and Samsung's own 'Appoptimizing' feature (same as Doze in Android 6.0).
So my battery life is pretty awesome.
i have problem whit battery lose 25% when i sleep
This is a usual day with s6 edge plus
Any help?

i have this problem battery ... if u fixed it tell me how?
Well I was expecting Google Play Services to be eating your battery (which is quite common) but it looks like your Andriod OS is eating the most battery. I would uninstall Facebook and use the web version it always helps with the ram and battery furthermore, turn off location if you are not using it and check accounts which are being synced. These are the only tips I can give you as I have never seen Android OS drain so much battery.
Since a few days Google Play Store is eating up my battery: I go to sleep with 100% batt and wake up with 50%, if I check batt stats on top I have play store at 45%, with 5h active a d 2h of CPU.
Follows Android system at 5%.
Going crazy why...

You've charged your phone 4 times during that day. I can't see what's the interesting part here.
Hey guys.
So I noticed everyone here and anywhere else basically, complaining about the battery life on this phone after the MIUI 11 update so I used the debloater directly after getting the phone to have the best battery life possible.
Turned off all the suggested apps and services and I gotta say battery improved, but it wasn't what was promised by the phone's specs. I'm barely getting 4h SoT, without any heavy usage whatsoever, only social stuff.
The culprit for me as well has been the Android System, with over 40% drain every day. So I installed Accubatery to try and see what's happening with my battery, along with better battery stats.
What I found useful from the accubattery app is the permanent notification where it tells you, after a few seconds, how much mA will be drained in an hour of using the phone like the way you are using it at that moment. So I did a test. Had my phone on the home screen, doing nothing. After a few seconds the reading showed -180mA, which is awesome right? Then I locked my phone and left it at the always-on display for a minute or so. Unlocked it and the notification showed -980mA.
This is very VERY weird and I cannot find anything anywhere suggesting what anyone can do to combat this. I have more average battery drain when the screen is off than when the screen is on.
I have never reset my phone (and would like that to stay that way if possible) and the phone itself is a month old. It's really saddening to see other people are getting twice as much SoT.
Do you guys have any suggestions?

I was on Miui 11 for a few weeks and had ~8h SOT with AOD enabled all the time. Now I am on Pixel Experience and I have ~7.5h SOT without AOD so I am very satisfied with the battery life.
I advise you to wait for Miui 12, which will come very soon to the Mi 9T. Then everything will probably change again with the battery life...
