HI there. My battery life on my SM-N900 is very frustrating. Previously, I used a iPhone 5s and people told me that android was much better and has excellent battery life. Right now, I don't really like android because my iPhone battery lasted 5 hours of SOT. I purchased a used note 3 n900 which is apparently less than 2 years old (original owner purchased in late 2013 or early 2014).
I currently use the Dr. Ketan L24 rom. Both this rom and the stock 5.0 TW rom have bad battery life. When I turn the screen off, the battery life is very very fine and sometimes even goes up a little by itself. I left the device for 3-4 hours and the battery actually went up 1 percent!
The minute I turn the screen on, my battery is drain. I only get 3-4 hours of screen on time. I hear some people receive 5-7 hours of SOT.
I've tried so many different methods, including wiping the cache partition from recovery, factory reset, disabling system apps (all Samsung bloatware) with titanium backup pro, disabling wakelocks, alarms and services using Amplify, Disable sync, location, and having low brightness. I also have low power mode turned on the entier time.
I also don't use mobile data so that's always turned off. I use Greenify to greenify many of my apps, including facebook, messenger, instagram, etc. I have also used apps such as GSAM battery monitor and Wakelock detector and better battery stats. None of these apps show out of the ordinary behaviour.
The only thing left for me to do is to purchase a new battery, but before i do that I would like to see if I can fix my battery life throuh software. If someone could explain why my SOT battery life is so low, it would be much appreciated!

Here is another
My phone has been in my pocket all day not being used until just now when I made this post
I should also mention it is fully stock
looks pretty standard for stock to me. 5 hours for 23% of the battery? That means about 20 hours a cycle? seems very standard for stock.
If you want more then you gotta go custom ROMS and Kernels.
If your rooted use SET CPU to make phone clock speed 322-400 mhz when the screen is turned of.
But why is it awake so much?
Search for "AndroidOS Bug" and you'll get the answer.

This bug really makes it hard to enjoy the note 3 as a whole. I was plagued by this pretty badly until recently I sort of found a workaround.
Some time ago I found out, that in offline mode the bug is not present. I came across it, when i was in our datacenter where the cell signal is a nightmare. I turned on offline mode and switched WiFi back on (thankfully we have a WiFi active there) and the battery drain was very low with active WiFi and bluetooth (headset connected) over a period of several hours.
I did still encounter the Android OS bug afterwards, but then once after my phone was fully charged, I put it into offline mode for some time (30 secs or one minute) and then switched back to normal and that day I had exceptional battery life (whole day = ~12h with some time checking, messaging and checking mail, with ~70% battery left) which i assume must be the actual battery life that the phone is capable of without bugs.
So long story short:
possible workaround for the Android OS bug: put phone in offline mode for ~1 minute, then back into normal mode
I would love to read if somebody tried this and gave some feedback.
Hello,
I've experienced a sudden change in battery performance.
What used to take around 50% of battery now takes around 85%.
It happened recently, around the same time I started working at a new workplace. The reception is horrible there, maybe that's the issue. However during the weekends, it is around the same.
I was on 4.4.2 stock when it happened and since then I've flashed it again once. I've also tried a couple of different radios (and enabled LTE) and I've always had franco kernel.
Brightness was always on Auto (which I shall turn off to experiment battery life) and wifi is selected to be off when the phone is off.
I have still a few more experiments to do, but I'm considering using warranty services. What do you guys think? It's clearly not as bad as some of the other battery issues I've seen on this forum, but it's quite the change for me. I bought this phone in July 2013.
Here is an example battery usage graph. Charging finished around 1 AM and left it unplugged over night. In the morning (~7 hours) the percentage was at 75%. (5% / hr) Throughout the day, I have used it for text messaging only and by 6 pm, it's at around 13%.
Thanks for taking the time to read my long post.

You can check what drains battery with BetterBatteryStats. Google it and you'll find.
Thanks for replying.
I have tried that before an OS reset although I couldn't make much out of it. One main thing I noticed was a certain kernel wakelock which, after I googled, was responsible for LTE connectivity. Although this makes sense, I had good battery life even with the LTE chip being used (& auto brightness / wifi always on) prior to this battery incident. By good battery life, I mean 50-60% used by the end of the day
This has happened multiple times on my Galaxy s4. Today was the worst however. My phone was on 51% battery (supposedly) and then, the phone just turns off while I was in an app, without any kind of low battery warning, it was running as normal before this happened, I start the phone up again and bam, 1% battery remaining. Here it is on the battery screen:

My battery was dead by 2pm in the day which is also significantly worse than normal. This is with just 45 minutes screen on time:
and just 7 hours on battery:
And with no apps sucking up battery life.
Has anyone had this issue before and is there any possible way to fix this?
Charge to 100%. Pull battery. Put it back in and charge it again while off to 100%. If that doesnt fix it then get a new battery.

Hi ,
It could be lots of things...battery , phone not going in deep sleep , settings
First thing I would do is use an app like Better Battery Stats and really see what is going on ( kernel wakelocks) , who is keeping the phone up all the time , then i would review all my settings like FB , mail , location ...any syncing related app that may be going crazy and of course battery may be going bad
Look like a bad/faulty battery for me.
Sent from my GT-I9500
Keep in mind that battery percentage is never 100% accurate. All devices with batteries (with a percentage meter) has this.
But yeah, use better battery stats to check wakelocks.
Also a trick to calibrate the fuel gauche chip is to take out the battery for 3-5 minutes. It will be more calibrated than before.
Aloah!
I bought the S7 Edge and used it in stock version. Then I noticed that the battery loses over 10% per night. So I decided to install the Superman ROM with root and deactivated some Samsung Features. But the phone still looses over 10% per night.
I have disabled WLAN, BT and GPS. The only activated feature is the always-on-display, but this could not be the problem, because of AMOLED. I know that Samsung bloates their phones with useless things and I only recognize this battery problem (mostly) on Samsung phones. So I think the battery loss must have to do something with the Samsung features.
So my questions are these two:
1. How can I find the battery-using processes?
2. Is there a near-stock-android ROM which is fully debloated? On the S5 the stock ROM had 1,5 GB and then I installed one which has only 400 MB. So there was much Samsung trash removed.

since you are rooted start by installing either Wakelock Detector or BetterBatteryStats app and see the output of those in the morning.
also is it a used or new phone? if its used then the battery might be faulty.
also try 1 night with AOD off and see if that gets rid of the issue.
Its a brand new phone. Ok, I try these two apps.
But what is AOD?

Always On Display :: AOD
Does this really take that much battery? I mean, its mostly black and that doenst consume battery (mostly).

Id bet thats where most of your drain is coming from. Im just going by what I recall, but believe AOD accounts for 1 to 2% per hour.
I like having the AOD at night so I keep it on regardless since Im pretty much able to charge my phone at work or in the car, its not a big deal.
Ok, I deactivated the AOD but still got around 7% loss.
I'm using redmi k20 Indian unit from last 15 days. its running on miui 10.3.8.0 with august security patch.
these numbers looks impressive and tbh the standby is very good. it drains about 2-3% overnight in standby but but my problem is when i use it for like 15-20 mins for watching videos on YT or Netflix or even some offline videos it drains the battery drastically. and i only play this one game MLBB. if i play this game for like 15-20 mins max it takes up to 4% of the battery. i switched off the auto brightness,set the contrast to constant mode, ambient display is off. i don't use wifi or mobile internet on idle mode. i optimized the battery use for each of the single apps, location service is disabled, auto bluetooth and wifi scanning is off, set the network to LTE/UMTS(*#*#3646#*#*), google play services cache is cleared. i tried every possible option to improve the battery life and even hard reset the phone. from being a heavy user i turned to a casual user now for this issue. on antutu it showed current estimated battery capacity is 3580 mah where the design capacity is 4000 mah. im really confused now. is my battery damaged? is it normal with this device? is this kind of battery drain is normal? if i flash another ROM will it solve this issue? should i wait for upcoming updates at least till miui 11 or android 10? someone please reply to these queries and tell me if this problem is resolvable.

for some reason i cant post the screen shots
Please.
We already have a topic regarding battery issues, SoT times etc. There is no need for another one.
https://forum.xda-developers.com/mi-9t/help/battery-life-sot-t3949855
If I watch yt videos I can easily squeeze over 1hr20min SOT in 10%
Found a Solution yet?
Hi, Were you able to find a solution to this?
I could not find anything useful on the SoT thread.
I can't believe this SOT time and the drain, but will test my standby time, while sleep.
