I've been revamping this thread for new devices for years hoping to share some of the love with newer users. Over the time I've been on android, I've learned a few simple things that can greatly assist in the battery life of our wonderful smartphones.
If you get anything out of the thread, please don't hesitate to rate it and drop me a thanks!
If you read the thread and like the tips, have a new one to suggest, or have a revision, please post it.
On a similar note, moderators, thanks for the sticky!
General Lithium Ion Battery Information - This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for both Rooted and Non-Rooted users
1.Turn off all radios when not in use.
(Bluetooth, wifi, data, 4G/Wimax/LTE, NFC, etc) Use a widget like the default power widgets, Switchpro, or a similar app from the market. *Many rooted ROMs generally allows users to access these radios and other settings from the notification pulldown menu.* The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions. A radio searching for signal (if you are in a low-signal area) drains more than a radio with good signal, so again, turn 'em off when you aren't using 'em.
To manually turn off radios without a toggle, go to Settings>wireless & networks. This can be accessed from the notification pulldown and hitting the cog icon.
Wifi uses less battery than 3G, so use wifi when you can. Another important setting to note is more dependent on the user. If you live in an area without 4G LTE coverage (check here to see), then go into Settings>Mobile data>Network Mode and check CDMA Only. This will prevent your phone from unnecessarily searching for LTE coverage, which wastes a ton of battery life.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Set your screen timeout/brightness to something that fits you.
The screen is the highest drain of battery power on any smartphone. BY setting the timeout, you can prevent your phone from staying on when you don’t manually turn off the screen. Also, manually turn off your screen when you’re done with your phone.
Another huge tip is to turn on automatic brightness (it is enabled by default). This greatly reduces power consumption by constantly changing the brightness of your display, tailoring it to your needs.
Settings>Display, gestures & buttons>Sleep
I use 30 seconds.
4. Task killers used to be all the rage, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
5. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to Settings>Power>History. You can compare the lines from awake to screen on versus time on. "Time on battery" refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these times and they are the same, or if you note the difference (turn off the screen for a minute, then re-check and they are the same), then your phone is not sleeping.
One solution is to reboot.
I recommend two apps to help monitor:System Panel and Better Battery Stats. These two apps (explained in their FAQ's and descriptions greatly aid in finding those rogues.
Usually, SystemPanel will show an app that has gone "rogue" and is keeping your phone awake.
-This is done by hitting menu>settings>monitoring enabled. Then after some time has passed, ht menu>monitoring>history>change tab to top apps, and see if anything is above, say, 2-4%.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 2 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
6. Apps and Combinations to watch out for!
-Facebook- Tries to sync live feed all the time, HIGHLY recommend unchecking this box, as it creates a massive draw on data
-Skype- This app reportedly (I've seen it myself) likes to sync random data and open up the network for fun. Sign out of app when not in use to fix
-GTalk- This application keeps you constantly connected to all of our google contacts across of your accounts. I have several accounts that I must maintain, and by default the application had me signed in and maintaining a connection with all of them. Open GTalk, then hit each account and sign out to neutralize this puppy. Unless of course you want to stay signed in.
7. Manage your syncing.
This is a big one, and it differs from person to person. Go to Settings>Accounts and Sync, and take a look at what's going on there. Listed app titles means that there is an account syncing data. I, for example, have four email addresses, facebook, dropbox, box, weather, etc. That is bad. You should go through and turn off syncing for nasty apps you might not have known were accessing the internet, or limit the access of apps and services that you do want to allow.
The problem lies in the way this syncing is handled. Each app/service runs on its own schedule, making it particularly likely that your phone could almost always be establishing a data connection and trying to download data for your various apps. See step 2 regarding the app Juice Defender to handle this problem.
8. Vibrate/Haptic Settings
Vibration and haptic feedback eat up a surprising amount of battery. If you have the haptic feedback enabled, then every time you press anything your phone puts out some juice to make itself dance.
Settings>Sound>Vibrate on touch
Some apps have their own haptic feedback settings, and notifications are their own set entirely.
Tips for Rooted users:
1. Try out custom kernels.
By going to the Sprint HTC One Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use Rom Toolbox Pro, SetCPU, or some CPU clocking app in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.setcpu.com/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
(Note that setcpu has fallen off of the radar, but clocking your cpu to levels that suit your needs is still viable, although many argue that the android system's core management should best be left alone. Read up for yourself and make an educated decision)
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the cellphone battery is the cellphone battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 0-2 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 2-5 of screen on
* *Heavy usage – LOTS of video watching and games, pictures or video recording, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans. 5+ hours
*I’m sure everyone doesn't agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

Hello Biofall,
I was wondering how effective is the Snapdragon BatteryGuru app from qualcomm vs juice defender if you ever tried that app before? I have used juice defender with my EVO 3D but I didn't liked the that the app was turning off Wimax even tough my phone was charging while using it.
Not only are we fighting the screen. We are fighting the quad core processor. It seems to be very aggressive.

It's aggressive when it feels the need to ramp up. When installing several apps, the damn thing actually gets hot to the point where I put it in the freezer. [edit: this is dumb according to the device's thermal protection] I know that the components shouldn't be reaching those temps....
I'm on the lookout for more info on explicit effects of the quad core on battery life and direct ways to combat it.

Thanks! I've been scouring for empirical info for years and I owe a lot of thanks to other people.
Turn off Juice defender. In fact, uninstall it. You will see your battery life is actually improved.
Leave the quad core component alone. If the cores aren't being used, they're offline. Offline is essentially 0 power consumption. The only case I can see improving battery by disabling cores would be for games. Otherwise, its probably detrimental.

Juice defender has a large multitude of components. If some parts use more power for you, then you should post which of them you believe they were, before and after, possibly with battery graph screenshots.
On the last quad-core device that I had used there was a problem where the cores would ramp up unnecessarily for small tasks, so there is certainly a possibility for improvement.
On an unrelated note, there are other things that I want to add to this thread, including screenshots, so if anyone has anything to add, just tell me.
What I don't get is that a lot people seem to believe they know better than HTC's engineers. Doing things like forcing off cores, how do you know that's really saving power? For all you know, the power loss of enabling an extra core for a small task is insignificant to ramping up an already active core to do the same thing.
Sure there are some things you can do to improve power usage (such as avoiding wakelocks) but if you start changing numbers for how internal software power functions work, you should have some damn good reasons why. Even a graph isn't going to be terribly accurate unless you can substantiate the gains across multiple tests. Many of the improvements people mention often have an impact of less than 1% over the course of an entire charge, and that's nearly impossible to even measure. The battery percentage indicator is only an estimation and not only varies between device, but even varies based on the temperature!

Sure man, sure. There are surely negatives associated with turning off, down, or generally altering core performance. However, taking the decisions that HTC engineers coupled with HTC software designers implemented for mass consumption as the best option for all users is foolish. The reason we have a development community revolves around that concept.
Several of the things I talk about have an impact in terms of hours the device can function without being plugged into an outlet, which has little to nothing to do with battery percent levels.

Battery percent or how long the device is on is still a hard comparison to make.
You could do the EXACT SAME THING on the phone twice, from full charge to dead, and you'd get a different length of time. Batteries aren't that consistent.
A couple things that bother me:
1. You stick the phone in the freezer because it gets warm. The phone already has thermal protections that keep it from overheating. The CPU can deal with far greater heat than you know (70C isn't even a problem). Anandtech was able to run it through the entire gauntlet of its tests (which are much harder on the device than just installing apps) without it ever triggering thermal protection. Most thermal protections exist solely for the battery's sake, which in itself can deal with 50C while charging, or even higher when not.
2. In almost all cases, it is better to let the CPU drive itself as fast and as hard as possible in order to finish tasks. Let it turn on all the cores and such. Because once it's done, it can go back into deep sleep, where everything is off. This is why almost all phones, not just HTC ones, are designed to do just that.
I agree with Felnarion's sentiment. Juice Defender is probably wasting more power just measuring your battery usage than it is helping you save.

You could do the same thing and get different results, but in reality strong trends in usage are reflected in battery life.
As for this the CPU discussion, all that I said was that I'd like to look at more in depth studies or core process handling. So it bothers me too.
In regards to JD, it won't be making it into the next revision of the thread, as I have noticed unnecessary draw. Honestly android implemented most of the vital operations into the OS, so it is mostly useless coupled with the other tips and just general awareness.
Finally, the xda app is acting up, sorry for the clutter.

Thanks for the write up. I went from being a little unimpressed by battery life to blown away. Biggest saver from stock is dropping all the SYNC stuff. Totally unnecessary IMO. If you aren't consuming the news and updates (you know actually in the app), you probably don't need it refreshing. Still baffles me this is the from-the-factory type setup.
Phone used to eat 5-10% of my charge per hour with light use and barely make it through my "day" (~15hr away from charger). Now, after 6hrs. since it's been off the charger, I'm still at 91%.
Kill LTE and go to CDMA only if you don't have it in your area either, or it's still rolling out. Seemed to help too.
EDIT: And I should note my scores are with never letting the Data Connection completely sleep, so I can still get emails as they come in which I find important.

While I actually agree with what you say I do feel a bit different. I base mine on previous usage.
My days really fall into one of three areas. When you get old like me you will see your days are all about the same. :crying: My heavy use is going to be someone else light day.
For me I can judge based on different phones, kernels and roms. The 4g days I needed to have a charger at my desk. There was no way I could get through a whole day regardless of how many calls I made.
Now I am judging verse the LTE I had and and very surprised on how well its holding up even on

Not sure it works, like you said some of these apps just use more than they save. I am going to see what happens over the next few days and see if I can see differences.
Your Facebook and sync statement, man do those hit home! I still have a few phones at work that these guys don't get it.
Gtalk.. beh turns on when you flash a new rom.. People have to remember to go back and shut that sucker off!
Thanks for your post, I am going to show a few people this, maybe it will open their eyes.
My Moto X randomly started lagging heavily. It's unbearable.
It's not just a little bit here and there, the entire system is EXTREMELY LAGGY. It takes 30 seconds for the device to register a touch or perform an action.
I have root + stock ROM + gravitybox + very minimal third-party apps.
What the hell is going on?
Download an app that keeps track of CPU and RAM usage for each app. One of your apps may be keeping one or both of those at close to 100% usage and slowing it way down.

Many things could cause it. Backgrounded app crashing over and over (loop), malware (very unlikely), weird software conflicts, perhaps you froze an app that the system is trying to wake non stop, etc. Might be faster just to backup, RSDlite and restore. Titanium Backup and Ultimate Backup make it very easy with batch backups/restore. 2 key inputs backs up all your apps and 2 restores them lol. It's ridiculously easy
Also make sure you're not running battery saving mode, I imagine that caps your max clock speed to a lower value although it shouldn't cause THAT big of a performance hit.
Apps like BetterBattery stats or GSAM can also show you what's hammering your battery in the background and occupying your CPU cycles. I would take a quick peak at those tools first before I decide how to approach the situation.
What's happening is some app or software conflict is polling (sending commands to) your CPU non stop so when you interact with your phone each key press/swipe/action is put into what is now a long queue for the CPU to process it. Kind of like a lineup at a coffee shop in the morning, you wanna get in and out fast but they gotta serve the people in front of you first.

I've frozen a bunch of apps and it's been fine for months.
I also turned on CPU updates from developer options to see if anything is bogging it down. I don't see anything in battery stats either.
I wiped cache and dalvik cache and now it's fine. I've never had something like cache build-up cause this much of a problem before. Weird.
Has anyone been able to shoot video over 13 minutes with the flash on in the camera app on the S21 Ultra? When I pull for 13 minutes, the device gives an overheating warning and I cannot use the camera for 30 minutes. Is this normal do you have it?
When I check the temperatures with the CPU Monitor application, the processor is 52, the battery is 50 celcius.
Yea been the same with me, max i ever got was 16min video recording.
IDK how this is not fixed yet.
You can't use the phone like that, it will get damaged.
Overheating/excessive battery consumption is a common issue on misconfigured Samsungs.
First try clearing the system cache.
Turn off all power management. Deal with power hogs on a case by case basis.
Does it happen in safe mode?
If you did any major firmware updates it's factory reset time* otherwise find the root cause(s) and correct them or find a work around.
Try disabling Google backup Transport and Framework. Firebase too.
Still doing it?
Disable Google play Services see if this help.
*factory reset if you used SmartSwitch to move data from an old to new device. It's a known trouble maker.

140F is way too hot.
Find what apk(s) are using the power and deal with them directly.
Disable useless bloatware you don't use. Cut out Google constant background bs if you don't need it. All cloud crap, the WhatsApp, FB etc. crapware... kill it. Carrier, Google, Samsung and apk feedback, disable it.
Take out the trash for starters.
My 10+ uses 7-11%@hr SOT. It use to be a hot running, battery eating hog though.
S21U is heating up if you take videos more then 10 minutes and there is nothing we can do about it. It's in Samsung's hands. Or maybe in God's hand.. Mine is only reaching 45°C, but that is still to much.

Use the tools you have to examine and look for the cause(s).
Is it a memory leak?
What apks and services are running, what's their memory usage?
What new ones open up when you shoot vids?
A package disabler is a useful troubleshooting tool.
It may be scoped storage rearing its ugly head but I don't think so. Check all settings in used and associated apks/services.
Try a hard reboot.
Try clearing data in the problem apks and remember to keep dependencies in mind.
Disable all power management as it can cause erratic behaviors. Are any cloud apps running?
Look at all Gookill settings and disable Firebase if not needed. Try temporarily disabling Google play Services, see if that gets it...
Play with it and keep exploring until you find a fix or work around.
It ain't no plain Jane dumb Apple, you have many options and tools at your disposal.
Androids wuv attention... sort it out.*
* my 10+ was a hot running cpu/bandwidth hungry hog. After a -lot- of optimizing its now a fast, cool running, battery efficient, very stable platform. I don't update the OS at all. Still running Pie. Keep a fixed constant rather than constantly introducing new variables, and new issues. Fix what you got... and be happy.
Forget the constant update hyperbole... it's not needed to run Android effectively.
@blackhawk, thanks, but I'm in this game for a long time, so I think I know what I'm doing. I rooted and installed my first custom rom over twelve years go. I use to flash windows mobile 6 roms back in the day.
My phone is not running hot in general, I optimised everything I could and it's running absolutely fantastic with great battery life. The problem is just with the camera system that is very power/cpu hungry. Only Samsung can do something about it. I've seen dedicated cameras overheating and shutting down.

My phone is not running hot in general, I optimised everything I could and it's running absolutely fantastic with great battery life. The problem is just with the camera system that is very power/cpu hungry. Only Samsung can do something about it. I've seen dedicated cameras overheating and shutting down.

That maybe true but if you stop looking...
Hard to believe Samsung or the reviewers didn't spot that. Factory load version of the apk?
Troubleshooting a stock Android can be counterintuitive worse not as many diagnostic tools available in the name of privacy in 10, 11.
Samsung will eventually punch out an update if it's large batch of phones that are effected.
However during a production run chipsets and smaller components may be substituted as needed. This can create a sub batch of that production run. The firmware update may not fully mesh with the different parts. Samsung is notorious for doing this and sloppy with the records. To even know if it's an issue they need to physically examine the phone.
They can then amend the firmware* or in extreme cases replace the part(s).
You see the implications here... yes it's a crap shoot if the firmware isn't working. In rare case the only way it will be fixed is to send it in for factory service.
*that new firmware update will then be punched out.
Will Samsung fix it, not likely based on their history. Exynos SoC's have had heat disapation issues for years Maybe will see a better offering in the S22.
@varcor, your point is? ANY phone can get hot under certain circumstances. This is not about Exynos. I still don't have OVERheating problems with my personal device. I've never seen the overheating warning.
But you do you. See if you can get more people to sign that anti-Exynos petition or make as many post as you can to convince people not to buy phones with that problematic Exynos that should be avoided at any cost. Keep the hate going. Wait, I forgot that you already know, nobody is buying them, so why go to all this trouble? It's already dead. You can relax now and retire your account.
Why did you edit your post?
When will Apple, Xiaomi or Oneplus fix their overheating problem? Maybe next year.
What power mode is it running in?
Play with the settings.
Sucks being a paying betaware tester...

First you state you have no overheating issues then you state you do and there's nothing you can do about it. So which is it? Snapdragon has heat disapation issues as well and here's why. Qualcomm agreed to allow Samsung Foundries to manufacture the 5nm 888 Chipset and they regret that decision. For the upcoming 895 they're pulling out and moving production back to TSMC - Taiwan. To this point Samsung in it's fixation to win the benchmark war continues to boost clock speeds. They haven't been able to manufacture a SoC that doesn't overheat in a very long time. I gave up on Exynos after my S8 and very happy I did. No comparison in heat issues between the Exynos and Snapdragon variants, Exynos losses that battle by a huge margin. Nothing you can argue will change that fact, it is what it is.
Qualcomm Snapdragon 895 to Ditch Samsung, Use TSMC Cores to Fix Overheating in Snapdragon 888 - News18
The Qualcomm Snapdragon 895 has been teased to feature 4nm Kryo 780 cores, a Snapdragon X65 5G modem, Adreno 730 GPU and more.

140F is way too hot.
Find what apk(s) are using the power and deal with them directly.
Disable useless bloatware you don't use. Cut out Google constant background bs if you don't need it. All cloud crap, the WhatsApp, FB etc. crapware... kill it. Carrier, Google, Samsung and apk feedback, disable it.
Take out the trash for starters.
My 10+ uses 7-11%@hr SOT. It use to be a hot running, battery eating hog though.

I installed the software from with Odin. Nothing is currently installed on the phone. I'm using Samsung own camera app. The same. Latest update is installed. While charging, the battery rises to 58 celcius.

Keep the battery below 102F. Li plating is possible at high temperatures. At 103F stop the charge cycle.
Heat and high cell voltage kills Li's.
Do Not discharge below 30, 40% is better.
Charge no higher than 90%, 80% or less is better.
Never attempt to charge an Li at 40F or below!
Do not charge with screen on. Make sure cloud crap isn't going nuts in the background.
Listening to Poweramp via bt is ok during charging though.
Cool it. Fan and/or moist microfiber cloth.
87-99F is the optimum fast changing temperature range.
Below 72F Li plating may occur and fast changing may not engage.
Li's love frequent midrange power cycling from about 40-70%
Charging from below 20% is stressful on the battery especially if the temperature is not kept below 100F. Break and allow to cool.
Ambient temperature where I'm at is 90+F and I have no problems staying in the green zone while fast charging with a 25w brick using the above methods on my new 4300 mAh 10+ battery.

Factory settings aren't necessarily optimized settings. Trust nothing... and generally some bloatware you don't need or want. Google is just as guilty of this. Crap like Google Firebase.

Is that normal? The phone is not being used, lots of things off. I also get high temperature readings in Good Guardians from "environment" even though its not in a hot room or being heavily used. Ive had this phone checked out by Samsung due to soso battery. They said everything was fine and just reset my phone.
I'm not familiar with that specific app. Maybe try kernel auditor? https://play.google.com/store/apps/details?id=com.smartpack.kernelmanager.release

Samsung's customer service used to be decent, responsive and accept responsibility but that doesn't seem to be the case anymore. Devices running hot with poor battery performance isn't normal and it's far too common, particularly with the Exynos SoC. If these issues have plagued you from the beginning you might consider elevating your complaint to whoever is the consumer products regulatory body in your region. If you've lost confidence in this model press for a full refund instead of a replacement. We're reading more and more legitimate warranty issues being brushed off. It's time to lean on Samsung for their dereliction towards their customers. "Everything's Fine" Enough already!
Clear system cache.
Delete Google play Services data.
Find the background apps causing the trouble.
Cloud apps, thrash apps like WhatsApp, FB, etc.
Android is what/how you load and optimize it!
Parent apks and dependencies; using power management can increase battery usage permanently. Many apks and services are interlinked. Keep that in mind if results aren't what was expected. Deal with each power hog on a case by case basis. WYSIWYG.
For an experiment temporarily disable Google play Services especially at night.
Google Firebase, Google backup Transport, Framework and Playstore are habitual offenders.
Try safe mode at night.
An optimized system should use 6-11%@hr SOT and >[email protected] at night. That's on an older and less efficient Note 10+... you should get better battery life than me.
Apps using scope storage like Office apps will use more CPU cycles and battery. Blame Android 11 for that.
With Android each user and load is unique. If not running well...
Play with it...

Your device is fine, its just a very badly designed app!
The blue line you see is basically your CPU Speed not the usage! as you see in the middle the orange line (device temperature) goes up, the cpu clock rate (cpu speed) comes down so the device is "throttling" (you can google this to find out more) inorder to not overheat. (This DOES NOT mean that its overheating! its a design and every phone reduces frequency and its normal while you using it with intensive applications like camera, gaming, video rendering etc).
Over heating is when your devices temperature still rises beyound the restrictions of the cpu speed and you get a message saying something like "device overheating, cant use camera right now, try later once cooled"
It doesn't look right to me. Try a different app such as AIDA64 and see to it yourself.
As the title suggests, I've been having some magical heating issues.
It all started a couple of days ago when my phone was in my pocket, the only two things running were a workout app (Strong) and YouTube (Vanced. RIP). I felt the phone was hotter than normal so I shut it down, waited 10 minutes and then turned it on.
To my surprise, it was still heating up, even on idle. Too much in fact (reaching a scorching 65°C). At the time I was on PEX 12, and blaming the rom (I was fuming like my phone, trust me). So I quickly switched back to Voltage (best A12 rom. Fight me) and it was still heating up.
So I did what any sane man would do (?). I flashed the stock rom (using the Mi flash tool, which I hate with a fiery passion), did a clean format of everything, and came back to voltage.
But the heating issue still remains. Further testing shows that the CPU is working way too hard for no reason. The battery seems to be chilling at 33°C.
Meanwhile the CPU is idling at 45°C with nothing running.
CPU usage is also pretty high.
Please check the screenshots below and tell me if this (and me) is normal or not.
Any help will promptly be reciprocated with a passionate pressing of the thanks button.
PS. It would help if someone could show their temps on their K20 Pro for comparison (using CPU Monitor from the Playstore, it has a green icon).
So no apps or services are showing excessive battery usage?
If an app or service isn't doing it, and it's on know good firmware... sounds like a mobo failure.

Should've added the battery screenshot too.
Yes, the Google app seems to be hungering for more juice than normal.
Even with that, the battery timing seems to be fine.
I've disabled it, and the temps are still idling at ~40+.

Were you watching vids on Brave? It's usage is extremely high; I get about 8%@hour SOT with Brave.
Your Google is out of control... tone it down. Try temporarily disabling Google play Services especially at night. It you don't need cloud backup, kill it. Disable Google Firebase.
Not sure what's going on there but that looks like software issues. Try using the factory load versions for the Google apks. Check AR core apk usage if you have that.
Try safe mode.
♤Disable all global power management and deal with power hogs on a case by case basis.

I wasn't watching videos on Brave, I was downloading a large rom file, that's about it.
I will try all of your suggestions one by one and then update this post.
I did try safe mode to no avail, a month ago Voltage would drop 1% in the entire night, now it dropped 15%.
It has to be GPS.
What do you mean by factory load versions of the apks? Where do I find them? I just flashed nikgapps.
Thank you for the detailed advice.
