Battery Problems

I'm using a Nexus 5, its my first Android device, and so my first time rooting.
I rooted yesterday using the Android SDK, and installed TWRP.
The root worked perfectly, and I have tested it. All I have done since rooting (unlocked boot loader at the same time, so I'm clean on stock), is install a few Play Apps like Twitter, WhatsApp and then BusyBox and dSploit.
I haven't added any customisations or anything, and my battery is now awful!

My screen has been on for 50 minutes...
I have brightness on the lowest setting, have turned off vibrate on touch, turned off Wi-Fi, turned off Location, set to use 3G not 4G, set display to turn off after 15 seconds...
Im sure it can't be anything to do with the root, but I don't really know too much about it. Is there a problem with 4.4.2 and battery life?
What else can I do to improve it?
Ideally I'd like to be able to have a max of 3-4 hours screen time, and the device to last for 14-15 hours.
I was easily getting 14 hours before I rooted/updated, but now my battery life has just screwed up.
Why is the OS using up so much?

Is this not the first charge since you first saw the problem? The Android OS bug occurs sometimes. I would reboot and see how it is on the next full cycle.

sreen may be turning in coz some apps might be asking for root access.
I think you try greenify app and hybernate useless apps, m sure this will help you.

Alarmclock works while Android is shutdown?

Hello Forum,
why does my alarm clock work while the phone is turned out? What is the name of this function and how can I turn it off?
I think it uses battery, because I charged my old phone (switched off, emergency phone) a week ago and now its empty.
Thanks
Peter

Hi, what phone do you have ?
I remember this was an issue for certain phones (but that was 6 years ago lol). Your phone must be really old !
And about the battery life when shut down, how long does it last usually?
Now for the upfront solutions:
Delete the alarm you sat up.
And if you have a removable battery on this phone, removing it would have a very good effect on battery life.
Have a good one

Its an Elephone P7000. I want to charge it and use it as a secondary phone. I turn it only on when my main phone has no battery. Last month I bought a new battery for this phone, on the battery is written "production date 2015". The battery last a whole day when the phone is turned on.
I'm really interested what is running the whole time in the background when Android is turned off. Is it some kind of BIOS? Is it the bootloader? Can you give me the name of this "program"?
PS: When my Xiaomi phone if turned of, the alarm does not work.

A battery life thread which may help is:

PS: I have never heard of an android phone that respects alarms when the phone is off, as android is not running But I always wondered why not, since my previous non-smart phones all did.

This App analyses the energy consumption of Android and the Apps, but that is not my problem. My problem is that the charged phone loses energy while it is turned off.
And secondly I'm really interested what is running in the background while the phone is turned off. Is is a firmeware from Elephone? I removed the original Elephone rom and switched to Cyagenomod and then to Rublix. But original Bootloader and other Elephone stuff my still be there.
I asked in a german Android forum and they said it is the fastboot function. But I think this is only a possibility of Android to boot fast when is is wakened from the watchdog I'm searching. (That the alarm clock starts immediately and not minutes after the targeted wakeup time.)

Yes, when you flash a custom ROM, all you are really changing is the system partition itself and maybe the kernel, everything else from your original firmware is still there: e.g. bootloader, modem, etc, etc..
Fastboot has nothing to do with how quickly the device boots, fastboot is a bootable function/mode used to flash/manage the device using the adb/fastboot software while booted into fastboot mode. Some devices have a feature that allows for fast booting, but that is a different animal than fastboot.
Your device has an internal clock the same as a PC does, that is how a PC keeps correct time even when the system is powered off and still shows the correct time when you boot the system. As for what is causing the battery to die even turned off, that may be a different issue than the power used by the internal clock.
All of my old devices lose charge after sitting in a draw for some time without being used, it isn't really an "issue" or problem, it is just the nature of the beast. Batteries do not store power indefinitely.
You can find out more about lithium-ion instability and the particulars of their construction and how they actually work if you do some google searches on the subject.

Are you rooted? running Magisk?

The smartphone is rooted with SuperSU.
This watchdog is more than a Bios clock. It wakes the smartphone at a given time. So the android system configures this background watchdog somehow. Maybe there are more things that it can do?
My Motorola Moto E (LineageOS) starts always with a wrong time. (WhatsApp is complaining about it at the start) So there seems to be no watchdog.

OK, if you are rooted, I would try running a boot-script that logs what is running on your phone every X minutes. If your lucky, the boot-script will log while the phone is "OFF".
something like the following maybe:
Code:
#!/system/bin/sh
top >> /sdcard/runnig_processes.log;
You may need to find a path that is actually mounted in your "OFF" state.
Also, I wouldn't keep this as a permanent thing, simply a test.

I dont think that this works. The uptime shows that the smartphone is running since 6 hours. I think if I put the script somewhere in the android system it wont be executed while android is turned off.
I have done some search. It seems that the P7000 has a Real Time Clock (RTC) in the MT6752 SOC. This chip can be configured to wakeup Android. I can see it at "cat /sys/class/rtc/rtc0/name".
There is also the charging screen despite the phone is turned off. The SOC can do a lot of things when android is not running.

It does sound like android is not running on your phone for the phone-off-alarms, since it has a real time clock (I didnt read it, sorry).
As for the charging animation, all my phones have that too, but I think that is only the bootloader and ONLY while charging. ie connected to power, so discharging isn't an issue.
I suggested the above, as waaaay back when I modified my first phone, when I added a bunch of boot scripts that logged heavily, I *think* i was surprised when I noticed once (its back in gingerbread days) that I had logs from the start up of when I turned it off. But that was now many moons ago. It was just an idea, that shouldn't be too hard to test, even though all you have said points to it failing. And now that I think of it, the charging animation on that first phone I had, was actually PNG images (as animation frames) sitting on the android file system path; but again, that was during charging, not completely off.

Android 12 - refresh rate is broken, 90hz all the time

I just noticed that my Pixel 4 XL (currently has the newest Android 12/November patch) does not cycle between 60 and 90 hz anymore. I just noticed an unexpectated and new drain on the battery and finally found the culprit.
Yes, I checked developer options, the phone is NOT forcing 90hz. I checked with developer options (show refresh rate) and the phone is constantly, meaning 100% using 90hz, it never changes to 60. No matter what I do - Youtube, phone, scrolling, doing nothing, idling, homescreen, newspaper app, Audible - it matters not. It is constantly forcing 90hz WITHOUT having ever clicked the 90hz force toggle. This is putting a drain on the battery that is just unacceptable.
Can you guys confirm this?

Try clearing the system cache.
A factory reset maybe be needed after a major OTA firmware upgrade but there's no guarantee it will resolve it.
Updates tend to break things...

The phone was - actually - already factor reset. After doing the Android 12 update, I factory reset it and gave it to a family member, that one set it up new. So it's not a "remnant" of Android 11.

I would re-flash with the latest full image, leaving the script intact (allowing the data partition to be wiped). This may be inconvenient but it's the only way you will know if there is a hardware issue with the phone. I'd also like to know what led you to the refresh rate. In other words, what made you look there. The stock battery monitor is not very good and even looking at system apps (screen, ambient display) you only get time and a percentage of the battery.

is the same on 12 and 11, i just installed 11 and is always 90hz

yes i can confirm, i had the same issue and i just boght my pixel 4 xl 10 days ago. updated to android 13 beta now and it still has the same problem. really weird but i think that google just decided that its best for google pixel 4 owners to have 90hz all the time now cause u know its "more common" now

Google changed how Smooth display works during the cycle of the phone. IIRC it was the same on A11 too. Basically the only time it goes 60hz is during battery saving mode & in some specific apps that prohibit it. It also disables it when HBM is on.

That doesn't make a lot of sense, you can save much more energy by just raising to 90hz for touch and animations and otherwise reduce to 60hz independently of the battery state.
I had the pixel 7 Pro for a while and can confirm that it works there as expected (60 for static content & no touch events, otherwise raises up to 120hz), just not for the pixel 4 XL.
This does seem like a bug to me and explains why battery life (SOT) got so much worse. I wonder if it's an intended degradation to get people to upgrade..

Fix it with adb, set minimal refresh rate
adb shell settings put system min_refresh_rate 1.0
adb shell settings put system peak_refresh_rate 90.0

Tested that, does not work either unfortunately. Display stays on 90Hz all the time

Confirm you have extra dim disabled, and brightness 60%

Confirmed, does not make a difference

Out of nowhere it started working. The only thing I changed in between is brightness and extra dim, ending up with the same setting as before (full brightness, extra dim disabled). Didn't work straight away, but after leaving the phone for 5 minutes and picking it up again, I immediately noticed (display refresh rate setting was still enabled)
Thank you for your help, Hamid!

No problem, glad i helped!
Feel free to visit my optimization threads, it might help improve your battery life and performance.

One last remark: It didn't really work well at first, at least not as consistently as on the pixel 7 that I've tried. After some trial and error, playing around with various settings, the culprit seems to have the "increase touchscreen sensitivity" setting that I had enabled. Since turning it off, the switching between 60 and 90Hz is much better. Brightness and extra dim don't seem to play a role.
Battery life also seems to have improved a lot (now at ~50% at the end of the day compared to <20% before)

Question My battery drain is insane!

Hello everyone, I'm in trouble.
22 Ultra is simply eating battery at indescribable levels. Yesterday we went on a trip from work, I left my home with 100%. During the day I did not touch the phone, a bit of a camera but beyond that really nothing. My battery was about 40% after about 3 hours, with no screen use at all! On the other hand, a friend at work with Xiaomi came out with 100% and after 3 hours was on 85, and he did touch the phone here and there.
I don't know how that makes sense, and it's no longer clear to me what to do to solve the problem. I debloat, deleted and disabled a number of irrelevant apps but still, the battery is being eaten. How can I solve it? Please help me!

Draining battery so fast, 20% per hour while idle is not normal, so you definitely have a problem.
It looks that there are two possibilities here:
- Battery malfunction
- Some active process in the background that is using lots of processor power constantly.
If battery is damaged / not working properly, the only solution is to replace it. Still, this doesn't look like a case of duying battery.
If you have some persistent process running in the background that you can't get rid of by debloating, it can't be stopped by restarting the phone, and its not visible in the battery usage section, i would say that factory reset is the most effective option here, since you stated that you tried to deal with it in a various ways already.
You could also wait a bit until you get chance to update to OneUI 5 / Android 13, which should solve your problem, if it's software related.
Hope that you will find solution soon

I want to keep the factory reset as the last option....
Every single app that I don't need at the background I disabled from running in background.

Try to wipe your system cache.....it won't do a factory reset but might solve the issue while keeping your phone as it is.
Volume UP button along with the power button until you see Android screen
Scroll down with volume down until you reach wipe system cache and reboot
sometimes, it won't show up while you press the buttons....in that case, connect your phone to your PC/Laptop with any USB C cable and then do it.
Second solution, you can try Samsungs App Booster.....get an apk from the net. It generally helps as well.

Does your V10 keep the Display timeout setting after a reboot?

Hi, I am currently on bit of a witchhunt with my V10 (H960A, running V30C-EUR-XX). For some reason the standby drain on this phone, which I bought used 2 years ago, is extremely high - about 60% in 12h. At the same time the on screen time is quite good with high brightness while watching videos I get around 6h SoT. Really bizzare.
One thing I noticed which is really strange is that when I change the display timeout in the settings to for example to "15 minutes" and I reboot the phone it always resets to the default setting which is "2 minutes".
So I would be really be thankful if someone could try this on their V10 and post the results.
Also I tried every trick in the book with this battery issue, from resetting the phone multiple times to running it in safe mode or flashing the Software with LG UP. Nothing yielded results. My theory is that something with the settings is messed up and keeps the phone in a "running" state while the screen is off.
