Hi! I'm new and this is my first thread. I have a POCO X3 NFC 128gb/6gb with root, kernel manager in performance mode (CPU AND GPU at maximium frecuency all the time, frequencies NEVER go down ), FDE.IA to the extreme performance, mode disable thermal throttling, Magisk module TherMods v2.0 for disable thermal throttling and custom rom Nusantara 1.1 LTS version android 10 with kernel kerminator. I have a few apps and so much free RAM (3.6gb approximately). But when the device baterry arrives at 10% there is a notable loss of performance (obviously it is a limitation of the system, kernel or battery). I have tried everything to remove this limitation but I have not been able to. Please I need help with this.
postscript: I NEVER USE BATTERY MANAGER OR BATTERY SAVER MODE.
Of something I am sure, the loss of performance is not due to the temperature. It is because of the battery level (specifically 10% to low).
Please I need help with this, if someone knows how disable this limitation of performance, comment pls. I would be very grateful.
Thanks a lot.

Looks like a limitation of your ROM, probably Battery Saver starts at 10%. Check settings - battery.
Also, you should never let it run under 20%, it's killing your battery life.
Welcome to XDA.
At 10% little usable energy remains. It's sort of splitting hairs.
Deep discharging Li's needlessly stresses them.
My cutoff is 40%, 20% max except for calibration which rarely is done. Li's prefer and benefit from frequent midrange (40-70%) power cycling. It can hundreds of additional full charge cycles to the battery's life. It's easier too as you can do a partial fast charge in 15-20 minutes. It yields more charge % per minute like that too.
If you don't care about battery replacement, again you'll get little usable time at full power in the last 10%.
Thanks bro

The power controller chipset maybe the cause. Maybe that limit is hard burned into it and that parameter can't be altered. It could be it can't supply enough wattage once the voltage drops this low. Don't know but I wouldn't lose sleep over it...

How do these interact. Do you get better battery life by using these apps. Or do they just work when you are running a stock rom??
I still use juice defender to turn off my data when the screen is off. And battery defender during my sleeping hours if I ever forget to charge my phone.
Battery opt apps usually prevent apps from using data, which in return doesn't drain the battery as much.
Custom roms usually try to govern the CPU frequency. For example lowering it to 1ghz instead of 1.5ghz. They can also change the voltage of the processor.
Basically custom roms and kernels will signifiatly change battery drainage due to processor changes.
Battery optimization apps can generally improve your battery usage depending on the apps installed on your device.

Seems to be a nice idea. But could you elaborate as on why the text is bold and you had to use capslock for 1/2 of it!?
@slind ok i fixed the post. i will be posting links to the posts who are great battery savers without loosing performance
So basically, we use an I9500 like an Ace or a Grand to get rid of heating and battery drains.. Andyou suggest that it won't result in performance loss. I'd suggest playing games that are more graphically intensive and not just Temple Run.. Try copying data from one memory card to another, or simply try running a Full HD Video. Also, check out web browsing or maybe multitasking, and you'll see where the performance dies out.
I think the fix should come in the upcoming releases of stock firmware by Samsung. By turning off a couple of cores, you're only going back a couple of years. I don't think I upgraded from the S3 to S4 for that reason.

everyone has there preferences and there needs in a phone. and there own settings. and this is a Battery discussion thread. we will be doing many performance and voltage mods, so everyone could choose the settings that suits them. now please dont post aggressive post like that, im not stupid. i know that my settings are very low.
but for my most played games and most used apps. it doesnt seem to effect my performance, so im comfortable with my settings
i had the phone for 2 weeks, happily showing off battery performance and then i asked myself again, why the heck i bought this phone in the first place? BECAUSE IT HAS REPLACABLE BATTERY!.. LOL.. how silly i am trying to squeeze that little drop of power out of the battery when I can double the battery just by getting another spare.
no need to turn off anything, no need to drop performance or screen brightness.. just pure enjoyment of the full potential without worrying battery problem.. just get a spare.

I didn't mean to be aggresive and sorry if you felt like that. All I mean is, there is a limit to which you can undervolt/underclock your phone without losing the functionality or speed. While underclocking to 1.0 ghz or 1.2 ghz sounds kinda normal, going all the way down to 800 Mhz and that too only on two cores is like running Galaxy Ace Dual Core instead. Why would I want to spoil my S4 for it?
That is all that I meant. And the phone is normally shelling out a good day's use in normal usage. Why bother so much about battery really???
My S4 i9505 came with MDE ROM from the factory, apart from doing dirty flashes over dirty flashes, finally someone came up with a recovery which is working. So i've :
1. Formatted system , cache , dalvik
2. Loaded in Djembey's stock slim deodexed ME2 ROM.
3. Using PimpMyROM, did some moderately less aggressive tweaks.
4. Capped the Max frequency at 1674MHz. Interactive gov, Noop sched.
5. Fully charged and unplugged.
6. Fully on 3G . Gmail sync for calendars, contacts, mail, keep, notes. Moderately heavy on Gtalk and Whatsapp. Browsing news and websites.
Observed 4 hours screen time.
Almost 15 hours of total usage + standby (This doesn't mean much, screen time depicts usage time more)
The phone still feels warmer than S2, under operation.
I've yet to try faux kernel yet, but i doubt it would get much better than this. The physical limit i feel is on the CPU, HD AMOLEDs, and the modem itself under normal usage.
Feel free to comment.
Hi,
hope you may be able to help. I have been trying almost everthing to increase the music volume as the s4 does not drive my senheiser headphones as well I would like. Is it possible to increase the gain through a kernel mod somehow?
Wow you're really random. This thread isn't even remotely discussing about the issue you raised.
Try the omega ROM thread, see if the functionality list includes volume hack.

Hello guys
I'm not a new user in kernels or ROMs .
I have a low-decent battery life ,and I'm sure there's a way to get a better battery life with undervolting .
I want to know
what is "undervolting" ?
What is the biggest damage it can cause?
What is PVS?
How do I know ,how much I can UV?
What are the steps to undervolt?
What I gain from UV (despite battery life)?
For your info ,I'm using AOSPAL ROM +FAUX's latest 16u kernel .
Thanks

Hi,
Most of your questions have a reply:
About undervolting: http://forum.xda-developers.com/google-nexus-5/general/nexus-5-undervolting-thread-t2537000.
CPU binning: http://forum.xda-developers.com/google-nexus-5/general/cpu-binning-nexus-5-t2515593.
The "risks" are instability like hard reboot, SOD, etc.... To find a "safe" value you will need to test by yourself to find what undervolting your CPU can handle, not all CPU's are equals.
Undervolt by steps like - 25mV, don't set your new values at boot unless your are sure it's stable (or you could encounter bootloop), test for a few days under different conditions (as your use).
The gain apart battery life (but you will not gain that much as people tend to think) is a little less heat, but again nothing huge..., better is to test by yourself and see what you will gain... or not.
Battery life depends mainly of your use, apps, signal quality and settings like, screen brightness, synchro, CPU governor, etc... In my opinion check first what could be the cause of your low battery life (and what is low battery life for you???) before play with undervolting.
As said above, undervolting will get you very minor battery life increases.
More than likely you have an issue, or its just your setup and usage giving you the battery life you are seeing.
Undervolting will not change any of this.... You'll gain only minutes of battery time.
Try some troubleshooting in the below thread to see if you have an issue, or how to setup for better battery life. Read through it a bit, from the last page and work back a bit. You can post meaningful screenshots there too. From gsam or BBS.... not the stock battery screen, it has no real useful info for finding issues. Good luck!!

Nexus 5 Battery Results
I've been undervolting many systems for many years, primarily Linux desktops and some servers, and the primary benefit is that you get less heat output which means when running cpu-intensive tasks the temperature climbs slower so the throttling of the clockspeed kicks in later, so your phone will be faster in certain situations. If you take a phone which has been idle for a while and run a benchmark, and then immediately run that benchmark again, the 2nd time gets a lower result as the phone is still hot from the 1st. This makes drawing conclusions about settings really dificult but it illustrate that throttling from heat is affecting speed.
For most users their perception will be the phone runs cooler.
You do undervolt at each step in the processor's frequency, and each step is a trial+error activity, the throttling I mention means finding a stable under-volt at the higher frequency which is labour-intensive,i.e take the max clock, and undervolt it a little, run a benchmark which forces it to run at high clockspeed, and if it passes that test then run it again at the next step down in frequency. Once you've got the most stable top clockspeed, then do it progressively for all the other voltages on the way down.
In some platforms in Linux and Windoze, we wrote scripts which save the stable voltages and then undervolts a little and runs a stress-testing benchmark and if the system hung it wouldn't save the current voltages so the previous higher voltages were safer, stick that script in a startup script area and leave the compute to do many self resets, and you've calculated your device's voltage range. I wonder if someone has that done for Android??? For a laptop the FAN would run slower saving battery time and for laptops that would lead to say 20% better battery life but on a phone it won't make much saving as no fan.
Your phone will run most of its time (like 95%) at its lowest frequency, so for effort/benefit just focusing on dropping its voltage will gain the most in the phone running cooler.
Battery life improvement is marginal, if you look at your battery stats its down to your application settings and screen brightness, i.e. how you use and what you do with your phone. So if your battery life is bad, use your phone less!
I carry a slim USB battery, it is the $/effort/benefit the best thing you can do, $20 doubles your battery life, if you get one with a 1.5A-2A output in just a few minutes when the phone doesn't mind a battery attached, will dwarth every possible tweak and hack anyone can form in benefit.
I used default stock ROM (6.0.1), RR (7.1.1), CM 12.1 (5.1.1) with squid kernel but still my battery don't get even 3 hrs SOT with greenify also. I mostly use it for facebook and whatsapp only. I cant afford a new phone due to this. Plz help me. TIA.

No rom will give you that much of a increase, stock is the best battery in general but there is no way any tweaking will increase that significantly.
Sounds like you need to replace the battery...

That maybe your opinion, but I disagree... Facebook Lite with it's built in Messenger is essentially a specially written browser, uses far less memory than Chrome, removes ads from videos (in general there are less ads throughout) plus you can still get push notifications. I have been using it for months.
If I am "completely wrong" give me some proof. In fact, although the regular Facebook is not the best, it is hardly "mother of all battery sucker apps". It is a space and data hog, but it doesn't use battery any more than REAL hogs like Snapchat, Netflix, Amazon Shopping, SoundCloud, or Outlook, in fact if you do some testing it has less effect on battery than you likely think (granted 2-3 years ago this was different, FB used to be one of the worst offenders).
Regardless, the OP was looking for an app to increase SOT... unless you can lower the battery usage of the display, you are not going to see increases in the magnitude the OP is looking for, from 3 hours to 5 hours, or a 66% increase in SOT. No app change or ROM is going to make a change even close to that.

3 hours SOT with greenify is a little off. you need to watch for wakelocks. better battery stats or wakelock detector can be useful to you. and also, if you have greenified the apps that you use the most, it will reopen those apps everytime you open the app, that could do more harm than good. you can try shallow hibernation, or just install naptime and tweak the doze parameters using GeraldRudi's method and quit greenify for some days just to see if this improves.
Then again, your battery could be the culprit, that's always a possibility
about ROM's, every ROM has it's merits, but Motorola really knows how to optimize their ROM, so for now, I think stock ROM gives the best battery life, even if that is marginally better than custom ROMs.
Kernels: Stock moto kernel is very efficient, but you might get a little bit more battery life with squid kernel, it has a great governor that relies on voting mechanism, plus it's just perfectly undervolted to get you some extra battery. probably a 15-20% difference than the stock one.
1) Use AOSP-CAF based ROM like Tesla.
2) Flash squid or Firekernel
3) Reduce the Max Freq to 1152Mhz and Min to 200Mhz
4) Use IntelliPlug Hotplug (Turn off Touch Boost and set Screen off frequency to 400Mhz)
5) Install Force Doze app and add Facebook, WhatsApp and other Battery consuming app to blacklist (Remember you will not get notifications from those app if screen is off).
6) Don't charge too quickly, always charge to 100% and plug when it discharged to below 10% (Recommended to charge at night).
It will improve your overall battery backup and somehow SOT.
At last i am totally agree with @acejavelin Facebook Lite app is made for low memory devices so it consume less memory and also less Battery. Also it's fast and have almost every features.
The real problem here is the device is going on 2, maybe 3 years old... the battery is at it's limit and will need to be changed to get really good SOTs.
My Moto G 2015 used to get 5+ hours SOT easy... not it's barely 3.5... and this is a backup device, it has NOTHING installed in it at all but it was used regularly for 18 months. The battery is just not what it used to be and if I am going to continue to use it as a alternate device I will need to replace the battery. Like it or not, these devices were not designed for more than 2 years of service.

downclocking the cpu is kind of redundant and saves less power than what it takes. the reason why for some users min-max is a battery saving governor. Besides, the performence hit is greater than the battery gained which is not at all more than 2% probably.
you should not fully charge your battery. you can, but the best practice is to charge upto 80%. And anything bellow 25% is not good.
the issue is either wakelock or dying battery, no tweak is going to save him if the underlying issue is not fixed, moreover, doze is the most sophisticated solution to save battery till now, downclocking, hotplugs these are pointless unless one's usage is known to us. I'd suggest to have doze editor if you must have a doze interface.
You can use aosp caf osprey by Ahmed hady...it will give 6 hrs plus sot from moderate to normal use..
As the title say, which ROM has better battery life among android P custom roms? im asking this because I did install stock android p and I faced huge battery draining on stock + heat. I don't wanna disable adaptive brightness for that either. So im wondering whether the battery life is batter on customs roms. If so please do mention the rom you have
i cant stand adaptive brightness not only does it kill battery, but it scales at the worst times and not in the correct intervals. i believe my preferences and environments change to much for the "machine learning" to do its magic.
ANYWAYS. I believe carbon rom with flash kernel gave me the best battery. i used the unified script with it, and enabled Smart pixels (on with battery saver, 75% move every 10 min) . With that setup i was able to get about 6hr SOT moderate to heavy usage.
Aside from that, any lineage based rom is going to be good on battery. A few people here swear by stock rom with a community provided kernel. Give elementalX a try on stock rom and see if it helps.
