Drastically Increase Battery Life -|- Tips and Tricks Everyone Should Know *4/26/13*

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!

Nice catch though, there was a lot there to change.

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.

Here's another tip: Go into Google Talk and make sure to sign yourself out if you don't use/care for the service.

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!

Question Good Guardians says my cpu is always running on max?

https://imgur.com/a/2RgUJBO
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.

Overheating

I bought my first Samsung phone in over 10 years, the Samsung S20 FE 4G with the Snapdragon chipset.
To my surprise the device is heating up very quickly while in use:
With light use, like messaging apps the CPU stays around 37 to 49°C,
While gaming it stays around 47 to 50°C+ (I believe the 60°C was the biggest temperature spike).
I've heard people saying that transferring data from your older phone via Smart Switch may cause this heating issue, but I don't think that should be a issue.
Lastly, I have no clue on how weather affects the phone's temperature.
Despite being winter, we're having temperatures around 40°C where I live, but even when the night comes and the temperature drops to around 20°C (right now it's 26°C and the CPU temperature is around 40°C, while I'm listening to music via Bluetooth and (re)writing this post) my phone still heats up (just not as much as in the rest of the day).
I think it's worth mentioning that the CPU temperature is also changing quickly, I don't know if that's normal or not but for instance, when I switch from one app to another, if the app I'm using to measure the device temperature (CPU Monitor) is to be believed, the temperature jumps some 2 to 5°C. It usually comes back down again, but I really don't know if that's normal.
I went to the Samsung store today, they checked, did some tests, and said that the temperature was at normal range, but they said that the temperature while switching between apps was a little strange.
They also said that their system detected a temperature spike caused by Fine Lock on the day that I bought the phone, which I find weird since it's only a launcher to the Good Lock apps, but nevertheless they advised me to uninstall it and keep monitoring the temperature for a few more days, and that if the device gets too hot (over 60°C), that I should go back again and ask for a replacement.
Anyway, should I give some time, should I worry about it, should I take it back to the store?

I have the same model as you and I haven't experienced any of the symptoms you are talking about. If I were you I'd return it and get another one. At least then you can be sure if it is normal or a defective device.

SmartSwitch isn't that smart especially between different OS's/devices.
I think you better start from the beginning...
Backup your contacts etc to the PC using cut/copy plus at least one other hdd.
Factory reset. Reload from scratch. Run factory loaded versions; do not update any at first.
Avoid enabling any power management at least at first.
See what you got and go from there.
It's likely not hardware at all but a bad configuration. Common with Samsungs and correctable.

Thank you. I'm thinking about doing it. I've talked to some S20 FE owners who live in my country (which is a very hot country) and they said that the device temperatures are basically the same as theirs, but at the same time I'm still worried about it's long term effects since I plan to keep this phone for at least two years.

Thank you, I did what you told me (except for flashing the factory stock ROM since I couldn't find it), I've only restored the apps using the Google backup, but didn't restore my settings. I've also did a mild debloat of the phone (removed Bixby and the Facebook apps) and while using the phone to browse through social media doesn't heat the phone as much as it used to, it still heats up more or less the same during gaming, so I'm guessing that might be normal.

Depending on how CPU cycle intensive the game is, it could normally use a fair amount of power.
Running background apps can make it noticeable worse though.
Try temporarily disabling Google play Services and see if that helps.

It's Honking Impact 3rd, it's not intensive like PUBG or something like that, but can be intensive depending on the game mode. It runs at 53°C max. I found out that one of the apps that I was using to measure the temperature apparently only shows the temperature of the hottest CPU core, that's why the temperature sometimes shoot up to 60°C whenever I took a screenshot for example, and then came back down to around 50°C.
But I'll try disabling Play Services and playing again.
Do you know if those temperatures are safe btw? Around 50°C while I'm gaming.
The battery's temperature doesn't go past 40°C, in fact I don't even think I've ever seen it getting to 40°C.
Anyway, thank you very much.

You're welcome. The Farenheit is scaled better for real world use.
140F is well within tolerance for the CPU/mobo as long as the battery doesn't get hotter than that. I don't let my battery go beyond 103F.
The CPU/mobo can handle up to probably 165F but it's best never to push it that hot as auto thermal shutdown doesn't always work in time to save the components that are running hot and have a sudden additional power usage spike.
Really the phone shouldn't feel hot... it's killing the battery too. Track them down.
If it feels warm when using the browser, something(s) are running in the background driving it up.
Any cloud apps, including Google backup Transport, Framework and Google Firebase.
Ditch any trashware apps like WhatsApp, Twitter, Instagram etc.
I'm using my 10+ in a case at a 75F ambient air temp browsing with a CPU temp of 89F right now. It is stock but heavily optimized.

The phone doesn't feel hot, unless I'm playing a game, depending on the game it gets somewhat hot.
It's been colder in my city these past two days, but tomorrow we'll have a temperature that's closer to normal. If the phone manages to stay in an acceptable temperature range I'll keep it, if not, I'll return it to the store and see what I can get done.
My old phone didn't have a plastic back, so feeling the phone warm is a new thing for me.
Most Google apps are disabled, I only use WhatsApp to talk to my family, I have Instagram installed but I don't even remember when it was the last time I've used it (I put it on deep sleep also).
Thank you very much once again.

Using power management can cause erratic behavior and sometimes increased power usage especially if set globally.
Developer options>standby apps, all buckets should show as active otherwise power management is running.

With Power Management you mean the Background Usage Limits from the Device Care app?

Once you do that you need to track down the trouble makers and deal with each on a case by case basis. Sometimes simply cleaning the system memory in Device Care can work wonders. Keep open apps to a minimum.
Here's the old version of Device Care. It uses 360° which cleans very well but is CCP junk.
To safely use it use Karma Firewall* to block its internet access. It will still run normally.
Before uninstalling your current version use Apk Export** to make a installable copy, just in case.
*freeware, uses almost no battery
**freeware that is very useful to backup all your apps and updates for future use... ditch Playstore for reloads

This is normal. Just because their bucket state is marked as active doesn't mean they are running. It simple means Android is no longer managing them by assigning a bucket state to them and so on. Google it... it sounds like a great idea but it never worked well for me in practice. Android still manages the apps with it off less the added resource burden of this system.

Sorry. You are correct.
I got rid of the updated version by doing a factory reset. You can try loading the older version by first force stopping the loaded version. It may worked... try this first.
I guess a adb edit would allow you to disable the current one. If the older one will load is another question.

I'll also test the phone again tomorrow when the weather in my city will return to normal.

Anyway, thank you very much, you've been very helpful!

My 10+ was a battery guzzling hot running hog before I optimized it. It took some time and effort
Today you never guess it is that same phone.
If there's any doubts get a refund. It could be hardware, even a heat sink or pipe issue.
That said this is a commonly seen problem that has nothing to do with hardware in Samsungs.
Do some Google searches for that device and hot running issues. See what you find.

I can relate. I had a Xiaomi before this one, and the stock ROM was plagued with app killing and battery drain. I'm glad you managed to work it out, all I had to do was switch to a custom ROM.
I've tested the same game again today since the temperature has gone back to normal where I live, and while the CPU temperatures are in acceptable range, the battery temperature got to 40°C/104°F.
I did some research regarding overheating on this phone and it's always the same thing, some have it like I do, while others say the phone doesn't even warm up the palm of their hands. So I don't know if its a configuration issue or if there are a lot of defective devices out there.

[Help] Mind Bending Heating Issue from Narnia

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.

Question Battery life on Indian ROM vs EU Rom vs Color OS

Hi Everyone,
I have the Oneplus 10 pro China variant and flashed Indian ROM with Oxygen OS.. Everything is working well and very smooth to me, however, the battery life is terrible with this ROM.
I'm having about 4 hours of screen on time (SOT). It is very weird, because with Color OS I was having around 7 hours of SOT and it was great for me.
Does anyone know if EU Rom is better than Indian ROM in terms of battery life?
I also have noticed that the charging speed has decreased, even it showing that is charging at 80w.
Thanks

I saw this EU member post 11 hours SOT;
Apps & games
Any essential apps and games for rooted OP10 pro?
forum.xda-developers.com

11 Hours, wow. Does anyone else is having bad battery life on indian ROM?
Is it also possible to flash EU Rom using Fastboot Enhanced?

Quick update on the poor battery life , just discharge to 0 and keep it dead for at least 20 to 30min and then charge it back to 100 using the supervooc .. you will have your battery life back.. doing this just once is enough.

The only way to actually compare the battery between firmwares would be to have nothing on the phone besides the same SIM and then see what the SOT is and in the exact same location.
The main factor besides a crap firmware is the apps you're running, the signal efficiency and your habits.
Comparing your phone with mine without these variables taken into account would be comparing apples and oranges..
You can figure a ball park figure but there will always be things not taken into account and a how the hell you getting them times questions.
For me the 11 hours which was more like 10 hours 50+ was in my house, great signal and I streamline all my apps and push for more battery as a rule, so if there's an app on there I don't use or an app i could swap for something better then I'll do it, Facebook app - use web version etc etc.
It all adds up.

Here's me at 48% with very heavy usage.... Been playing arkanoid Vs space invaders for over an hour.
Steadily on the way to 10 hours.

I can help you if you need it.
Let me ask you a few simple questions.
How many apps do you have installed?
How many mods?
How many social media apps?
What is your signal like where you are?
Do you charge overnight?
What launcher?
QHD or FHD?

This is my app usage.
Bare in mind the SOT listed is not from the length of the graph it's only from the last full charge which was around midnight last night.

I may make an SOT leaderboard thread...i had one of these on the OnePlus 5, on that device I managed 14 hours 47 minutes and I wasn't alone in SOT's like that either, I think this phone is capable of much much more.
My highest is 17 hours on a P20 Pro. Always provide proof and it's with normal usage.

Ok, I know it would be the problem.
I got like 150 apps but I should probably remove those I dont need and I dont use.
8 magisk modules, then I got FB lite app, normal messenger, whatsapp, twitter, instagram, telegram, discord, XDA app.
I live in Czechia on LTE+
No, I dont charge overnight.
Using Nova launcher,
FHD.

Lol ok so I think you know what I'm going to then don't you
Lose Facebook, use the web browser, not only are you stopping FB from spying on you, you'll be getting rid of an extremely heavy app, lite or not it's a battery rapist.
If you've seen the list of tips I sent to the other thread then honestly, just go through them, what's the worst that could happen?
If you don't use it then nuke it, lighten the load and let your phone stretch it's legs.
Think about it, two identical phones. One being looked after with not so many apps and kept light Vs a phone that's laden all the time, after a year or two. That extra work will be more and more apparent In regards to stamina.
Your phones super new, make a change now when it can still make a difference.
If you need help with anything let me know. If I was you I'd wipe the phone and start over.. don't add anything, just what you need and only when you need it, you'll be surprised what you don't use but you do install just from habit.
Also 8 Magisk modules?
What ones? I'm always on the look out for good modules. I'm using 3, two of them are for safety net and systemless, so only one really.

I'm on 88 apps total
Lol did a scrolling screenshot... Just wanted to see if it'll be visible
Edit: wow it did show, extremely well actually.. nice

Go through this little lot and if you still have bad battery life after doing even half of this then honestly i'm stumped.
Change 5G to 4G
Remove Facebook use web based
Remove Facebook messenger use web based
Remove Twitter use web based
Remove any ad based apps pay for the pro version
Turn off gestures like lift to wake
Change from QHD to FHD (No difference)
Allow auto brightness
Turn off WiFi overnight
Turn all updates to manual not auto (play store)
Remove any so you don't use
Change back up to once a month (WhatsApp)
Turn off location history (Google)
Use titanium to remove any system apps you don't need
Don't allow anonymous usage statistics for any app ever.
Don't allow tracking cookies on any website
Use adaway (root needed)
Don't open web pages in Google app (I use Samsung browser)
Don't use xposed.
If you game you will not get high SOT scores, period.
Don't bother with battery saving apps or monitoring apps.
Streamline your apps, if you don't use it, remove it.
Don't allow WiFi scanning (as in letting other apps use it when it's not on)
Never allow personalised ads.
Never allow notifications from websites
Always decline cookies unless your absolutely have to allow some tracking (common sense prevails here)
Optimise as many apps as possible unless it affects performance.
Don't allow apps to remain open in the notification area.
Change your launcher, my preferred launcher is lawn chair and this did actually burn up some battery when compared to the OnePlus launcher.
Don't use live widgets (yes they look cool, but they annihilate your battery)
Live wallpaper, again very cool, but battery burners.
Again! Don't charge overnight, make a note of your percentage then see what it is in the morning, you shouldn't be losing more than 5% really, if you've done well then it'll be reflected here, the good SOT results will follow.
Turn off live read outs of network speed, RAM usage in the status bar.
Turn off NFC unless in use.
Leave location on in quick settings.
Don't overcharge your phone, IE: overnight
Don't allow your phone to fully deplete the battery.
Whatever anyone says, this does 100% damage batteries, there is no argument here and I won't entertain anyone who says otherwise, Ive seen through real life tests what this results in, bloated, inefficient, possibly dangerous lithium batteries.
Keep your phone out the sun.
Keep it out of extreme cold.
Keep your device clean dust free.
Snapchat, Viber, house party, apps like that tends to use more battery as they don't have great dormancy periods.
Apps like speed test by Ookla tend to have location tracking, similarly they tend to turn themselves on and off when they feel like it, my advice, install test and uninstall.
Allow a couple of battery cycles between tweaking sets, to give you an idea of how much of a difference you've made.
Use BBS to see what is being used, once you've removed problems, remove BBS.
I've just written this from the top of my head so o probably missed some things, the general idea is to keep your device clean and fresh, remove files you don't need any more.
Keep an eye on apps that misbehave or aren't wanted, index your folders so they aren't a mess.
The more good things you do means the more potentially bad apps you can have on your phone, eg if you really need Facebook, you could keep it so long as you clean up other areas of your phone.

Thank, I'll take a look and deeply think about what apps I really need and how often.
It is also true that I have rooted phone, playing pokemon go in between which will strech the phone heavily, but this is a thing I count with.
And eh, I dont want to wipe the phone at all to be honest, because I hope that next system updates will improve whole phone, because I can also feel some underclocking and throttling.
And those modules: busybox, gpay sqlite fix, magisk bootloop saver, shamiko, systemless hosts, Universal GMS doze, Universal safetynet fix, Zygisk Lsposed.
Also during the night I am turning on airplane mode (losing only 2 % during the night).
I am also wondering how can I decline all allowed personalised ads and cookies of it is possible.

Lol the only reason i said to wipe was that it's a sure fire way to begin a good habit, by removing bits and bobs it's a bit of a patch up job.
I'd also get rid of xposed, I've always had bad battery life with it, but that's my exprience with it.
As you will have only had one update yes a wipe isn't required, however after a few updates, it's always a good idea to give your phone a wipe to start over, it just means that inherited or created issues between firmware iterations are eliminated, definitely do this if you update a full base ie: Android 11 to 12.
You'd notice this a lot when you update Windows on your PC, for example going from win 10 to 11 you'll almost certainly notice a few issues, giving your OS a wipe at that point fixes a lot of it and improves stability and performance quite a lot.
I agree with the underclock, but the SOC is already extremely efficient from my tests, i've never seen the temp go over 35c which is incredible for a mobile SOC.
Even running a PS2 emulator (AetherX2) it wasn't even warm to touch so throttling really shouldn't occur on this phone, running the PS2 emulator is probably the hardest thing any phone is going to have to do and it breezed it.
Not trying to be a dictator with you here btw, just some advice on what i've noticed over the years, it's up to you what you do with your phone mate.
Also Pokemon go, i think that uses the camera and location and gyros as well as the gpu and cpu lol so yea that's a heavy game for sure, don't think theres a way around that though, maybe just reduce your play time?

Onak extremely happy with those advices, I am just having bad habits at all and I probably think what apps do I use even if probably don't.
I actually don't need 11 hours of SOT, just want more than I currently have. It could be hard because of my habits, also I use my phone as a work phone too for some apps which I do test on daily basis.
And those wiping. I usually do wiping when upgrading to the major versions, because I also know it is recommended, many issues would disappear then. And usually they do.
I know how new this phone is so I am quite reserved with its software, but to be honest, we expect having the phone fully working without those underclocking etc, especially for that price.

This is a great thread because I've learned so much about making the most out of your battery, although I came here to find out how you flashed OxygenOS on your NE2210, yes? ColorOS is okay, but OOS is just cleaner in my opinion. Any help is greatly appreciated
