I can't find a conclusive thread on how to do this on EMUI 11. Someone on another thread suggested CPU-Z, but on my P30 it doesn't show the capacity only voltage. I don't want to use Accubattery as I don't find it reliable. Is there really no way to get the real battery capacity? Is there a procedure or app that works on EMUI 11 or Huawei devices?
i guess you could take the actual battery out and put that in something that could test it?

Are you saying that there is no software that can provide a reading of the stored energy in the battery? This data must be available otherwise the OS would not be able to display the percentage of battery available at any given time.
i dont know i dont have a huwaweii it was just a suggestion if you dont have another option

I read this: http://forum.xda-developers.com/showpost.php?p=6399061&postcount=3546
It says that you should get 100%, then turn it off and wait until it is green. After this, wipe the battery stats or use the adb command. Then, let the battery die after normal use, and after recharge..
My question is, can anyone recommend some battery killing apps that will do the job?
Thanks in advance!

Flashlight.
Thanks, i'll give this a try! any background apps? I'm gonna use pandora as well.

i think you answered your own question
That public embarrassment was not necessary. *sarcasm*
Yeah, but isn't using an application considered normal?
sorry, anyway, I used pandora overnight that worked pretty well. with pandora you can lock the screen on also that helps out.
I could be wrong but I thought that the way Lithium batteries worked makes this kind of calibration useless??

This dueling argument will go on for centuries. I wish a battery manufacturer would step up and release some white pages to say one way or another.
I don't think it is so much calibrating the battery, but calibrating the phone to the high and low points of the battery. Older battery types required conditioning, not calibrating.

Bingo! Having three batteries (2 after-market TouchPro 2 and the OEM), I even have a performance difference between the two types. I've since set the OEM battery on a shelf and only use the TP2 batteries, as they are identical. I haven't had a battery issue since calibrating using one of them.
Hello,
I'd have posted this to the dev section but the posting rules here require non-talkative people to fabricate 10 useless posts before they can post there.
I've noticed that "Cell Standby" is far and away my greatest battery user on my Nookie Custom 0.6.8 eMMC flashed device. Now, I'm sure this is just a mislabeled "Display" usage meter, but I wanted to make sure. I'd post a screenshot, but apparently I might be a terrorist since I haven't made ten posts yet so I'm not allowed to link images yet.
Thanks In Advance
As far as I know, the cell phone battery usage problem has been debunked. I could be completely wrong, but since the Nook lacks the necessary components, there's no actual way for the power to be lost in the process.
I'm about as new as it gets, though, so take that with a grain of salt.

Yep, it is debunked, ignore it if battery life is the concern. If you want different info in Spare Parts for partial wake, this changes it to Android System..

I believe this, however -- how hard would it be to find an app that claimed to track what was using the battery with any accuracy. Pretty sad that the built in battery monitor gives "credit" to "cell standby" for 50%+ of battery usage on a device that does not even have a cell. Anybody could build an app that hard coded battery usage stats in pre-defined chunks
I don't know why this bugs me so much...it just does.
Hey guys, could use some input if anyone's passing by. I've noticed that, as the title states, that battery drain greatly increases after going below the 50% threshold. I don't think its ROM related because its proportional. If a ROM has fast battery drain intrinsically, it will still be even faster after going below 50%. Just wanted to know if anyone else has experienced this. I think it might just be my battery is partly defective, or substandard. It doesn't seem like something software related. Anyways, just some quick comments is all I'm looking for. Mostly just curious.

its definetly your battery, just buy a new one and use your current one as a back up

Gotcha. Thanks man
I just found out that there is a live, by the second precise battery current stat on the Note 4:
Code:
/sys/class/power_supply/battery/batt_current_ua_now
But all the battery current monitoring apps I've tried on my Note 4 don't work, they can only use the "estimate" value that measures how long it takes for your battery to drop 1%. So far the only app I've been able to find that can monitor this stat is Cool Tool, but that's just because I can manually enter it in as a custom field. If anyone knows of any others that can take advantage of this, and perhaps log it (I'm a data nerd), please let me know.
Does this work on CyanogenMod?

Estimate what? Apps that run the battery the battery to 1% are the only way to actually and precisely measure the battery life of a device, since the batter capacity is at best an estimate and can be wildly different from the stated capacity depend on source and age.
'Current now' is a decent method of seeing current power draw, but in no way does it really provide any meaning indication of total battery life. What method of taking advantage of it are you looking for? It only has a few implementations where the data is of use. For most real world tasks, the data would be just an interesting nerd fact and nothing more really and cool tool can already provide what you're looking for.
not to sound like an asshat, but who cares? idk how or why but the note 4 by far has the crappiest battery life ever.
Can someone who actually has the phone post real world battery life test results with full res on, Bluetooth WiFi and GPS on, and without running YouTube to run down the battery.
I saw the video from the YouTube tech guy (thanks for all those btw), but these devices are optimized for video so running down the battery with a long Youtube playlist isnt "actual useage" if you know what I mean.

I don't think anyone here actually has the phone yet And to be honest if your not happy with the current reviews I don't think you will be with future ones either because it will never be 'your' usage and no one else can replicate that except you.

Yea a lot of people get the devices before the consumer release date to review them. Like this guy I know that it wont be "my usage", but I did stipulate a few conditions that would make it close to my use case and I wanted to make sure that streaming video on loop wasn't part of the test.

Understand completely.. i do not see the point in strategically getting high SoT or battery usage stats.. I just don't think it would help you someone else posting there usage for you to make a decision on. I assume you would be comparing it with your current phone with your usage
I've seen a video on YouTube that claims the screen on time is 6 hours and 45 minutes during normal use. That would be incredible
Found a great video on battery life

Seeing that video gives me hope. But seeing no updates to improve S8+ Is bull.
Just remember to look after your battery initially. When you first get your device charge it without using it. Once charged you'll be doing a lot of transfers and updates which will heat up the battery and device because of the load - I always do this initial set-up in a cool room or outside if cooler and without a case to keep the battery cool. Once set-up and you've played with it and the battery is drained, don't charge it . Switch off the device and let it cool down. Following this initial care procedure should give you better long term battery life.

Most manuals say charge fully prior to first use. Keeping the battery cool super important. Battery also better if charged with device off.

They don't need any initial conditioning, like NiCd or (to a lesser extent, NiMh), but ...

As @jah says, heat is the enemy of Li-Ion batteries. The cooler you can keep them, the better. Don't charge them when they're warm to the touch, and don't fast-charge them unless you really need to. I don't think charging them with the device off provides a significant enough benefit to go to the trouble of shutting down your phone before and turning it on after, though.
