Battery calibration HELP

So I love the phone but I just can't stand this battery anymore I'm starting to think t mobile gave me a used battery. Ive tried draining the battery to 0 then charging it to 100 nothing. I tried the restart nothing. I work from 8 to 4 and I start the day with 100 and end with 10 if I'm lucky! As I'm typing this its at 87% and its only 9:04. Running services like app pack car home and such are off wifi is off brightness at 50 and I kill tasks a lot with ATK can someone please give me a step by step on how to calibrate even if I have to mod the phone Thank you =)

I'm having the same issue as well. I just received my phone yesterday and I charged it fully last night and kept it unplugged over night. Overnight it only lost about 3%. But after medium ussage this morning which consisted of checking email/texting/surfing the web, the battery dropped a significant 25% over the course of 40 minutes. Any suggestions?

Root phone if you havent already
Charge phone to 100%
Flash clockworkrecovery
Boot into recovery and under the advanced menu select "Wipe Battery Stats"
Reboot

That kind of behavior is normal. The phone loses very little while idle but checking email and web surfing both require a data connection and that uses a lot of power. More usage = faster battery drain.

My galaxy s would easily last a full day with constant email/text and a couple hours of talk. This phone doesn't even seem to be able to last me a few hours. Do you also experience this significant battery loss?

You prolly need to do a factory reset. For some reason some peoples phones use more power even at idle than they should. My phone was one of them. There is a whole thread about it but pretty much doing a factory reset should correct this issue. Did for me. I get almost twice the battery life of my Galaxy S.

No need to go into recovery to wipe the stats, just use Battery Calibration(requires root) its in the market and also includes instructions on how to use the app.

true story. ive never used it so it didnt come to mind lol.

In the passed hour I've now lost 40%. That can't be right, can it? :/ I'm running everything stock btw and I'm unfamiliar with rooting and things of that nature.

I had the same problem. I followed the thread below and it worked. I've ben getting 10-15 on moderate-heavy use. I also did the htc battery calibration before I ran the battery calibration app. I use juice defender as well.

Check out the link jsauce75 posted. If you are running stock that means you most likely have background services running that are pulling significant battery. You will need to root and then use titanium backup to either remove or freeze those services.
Before doing that thought I would download Battery Monitor Widget. Use it to see how much power (mA) your phone is using. When I first got mine I was draining battery fast and when I used that widget I learned that the phone was using over 100mA even when idle. It was like the phone would never go into a sleep state. After doing a factory reset my phone idles at 1-2mA.
There isnt much you can do about battery drain while you use the phone because the screen and data connection are huge battery drains. All these tips are to improve your power consumption while idling. As I said before all I have done is factory reset and removed unneeded services and I have been getting double the battery life of my Galaxy S with the exact same apps and usage for weeks now.

1) You said you're using ATK "a lot". This is adding fuel to the fire. ATK is not needed with today's android systems. These apps you see sitting in ATK are sitting dormant. It's like the task manager of a computer. I have 3-4 apps running in my system tray and around 20 other services running in my task manager.. They are all sitting dormant, using zero CPU. They have ram allocated to them. That's it. That's the same as the Android. They are sitting dormant, and they have memory allocated to them. The best thing about the android OS is that it will automatically shut down dormant apps on its own. A PC doesn't do that. So, look at it this way. Let's say I'm on my laptop's battery. I have 20 apps/services running, and they are dormant. They are doing nothing towards drainage of my battery. But, I decide to turn on my screen "a lot" during the day, and kill the apps. Boom... Battery usage for the CPU to turn the screen on, the screen takes away from the battery, usage for the task monitor to be running.. Then, there is a process to shut down the apps, that takes battery.. Then on top of all that.. When the apps restart on their own.. guess what, they have CPU/Battery usage. You're adding fuel to the fire.... a lot of it, imho.
2) Install Watchdog and Titanium Backup (pay the small fee so you can freeze the apps.. or you can learn how to manually remove them yourself. I like using the app). Now, just to prove the point.. Open up ATK... Then go into Watchdog.. You'll see the apps that are running in ATK are not using any CPU. But.. when they do start up/shut down, there is some usage going on that will contribute. So with Titanium backup, freeze the apps. The apps I have frozen: AppPack, Broswer (have dolphin installed instead), Car home (2 of them?), com.android.provider. applications, com.logmein.resecuesecurity and .rescue, email (using gmail instead), My account (2 of them?), nfs shift, nova, street view, tmo TV, tegrazone, telenav, videochat voice dialer, zinio reader, zsprovider. From there, you can see the apps running in watchdog and you don't need ATK.. But, watchdog also uses processor to "monitor" the usage of other apps.. So place the threshold setting at like 40%, and the frequency at 3 or 5min. This will keep Watchdog from using too much battery, but it'll also notify you if an app is running wild on cpu usage. Maybe for 1 day, put the threshold at 30% or maybe even 20%.. so you can see if 1 or 2 apps are using a lot of power. If they are system apps or apps you want.. just leave em be. If they are not, freeze them/uninstall them.
3) I have found that using wifi and wifi calling GREATLY increases my battery life. As soon as I turn on 2g/3g/4g... my battery starts to take a fast dive. Whenever possible, use wifi/wifi calling...
4) Screen down to the lowest brightness setting. Shut off screen manually whneever you are done, or set it to 15sec shut off. I only bump up the brightness when i'm outdoors.. The glare makes the low setting impossible to see the screen.
5) Shut off syncing, bluetooth, and gps unless you need it. If you're around a computer at all where you can get your email and such, there is no need to use the phone for it. I only use tmo's network and syncing when I'm away from work or the house... typically when I'm on the road.
Lastly, yes, some people want to use their phone... use the 4g service.. etc. I understand.. But also understand that if you're going to use the phone like a computer.. and you're going to get 8hrs out of the battery... I say that's pretty dam good. This post is not meant to say that there is nothing wrong w/ the battery... It's to help you out to determine if there is a problem in the first place. There was a guy complaining about battery usage left and right. When I got involved in disussions with him, he admitted that he's on his phone all day long... txting quite a bit. Well.. duh?
I don't doubt there could be some challenges with a bad app running wild, a bad battery, etc. But I also don't doubt there are people who are using the crap out of a dual core phone.. and are doing things themselves to add to the problem... and then they blame the phone.
That's my 2c....

Thanks for the great detailed response. The OP actually was the one who stated he uses ATK, I don't. I looked through the thread with the recommendations for 20+ hour battery life and noticed that those apps you mentioned above required rooting the phone. I hate to sound so naive when it comes to this stuff but i'm a fairly new android user and have not yet discovered a lot of the technical aspects behind it all. I'm not exactly sure what rooting is and what it entails. Is it something you suggest I do? Also, my battery is slowly approaching 0%. Should I let it drain all the way before charging it again? Others suggested letting it drain all the way and doing a factory reset and that seemed to help their issues.

By default Android restricts certain areas of the OS from being accessed by third-party applications (prolly for security reasons). Only problem is a lot of great apps require such access to function properly. In order to give them that access you must root the phone.
Here is the rooting thread. It is extremely easy to do.

Does rooting affect warranty in any way?
or the ability to perform a factory reset for that matter?

New to android is not an excuse, I was a religious crackberry user for the last 8 years, and I just switched over to android last month. I'd suggest you to root you phone so that you can remove the stock cr4pwares, and the ability to install custom ROMs. Took me 10 mins to figured out how to install andriod OS into my hd2, 25 mins to perm rooted and unlocked my g2(this beast is little bit more "lockdown" than the other), and 5 mins to rooted the g2x. Google is your friend, bud. If you want something more out of your g2x, use the "search" button. Just my 2 cents.

FYI: I'm a first time android user (smartphone user at that..) and I rooted my phone easily. You can unroot your phone just as easy as you rooted it. It's a 1 click method with that software.. check out the link. Seriously, it's easy.
You may have to have ABD ADB or whatever installed first.. Not sure. I heard about it, and did it... and then rooted.. and it worked.

Thanks for the help guys, appreciate it. I'll let you know how it goes
I'm also having another issue with the phone. I'll see if you guys can help without having to make a new thread.
Yesterday I installed Zedge and downloaded one of the wallpapers there. When I applied the wallpaper I noticed a bit of lag on my home screens, so I reverted back to the default wallpaper and the lag was still there. I deleted the app and wallpaper I downloaded but the lag was still there. I applied a default live wallpaper and the lag disappeared and everything was moving as smoothly as it had been originally, but when I apply the regular wallpaper the lag persists. Any ideas?

now if u do root and remove bloatware what all is safe to remove i have all but my account car home and i think one other can anyone provide a definite list and battery is significantly better after just that

LOL think there's not driver issues. Swapped a dead battery with a fully charges one today and been running almost 2 hours still shows 1%

[Q] What is this thing that is eating my battery? com.android.systemui

Rooted -- Calkulin's Stock "Battery Saver" ROM -- Xposed Framework -- a few mods from XBlast Tools running.
First off, a Root Explorer search for com.android.systemui returned nothing.
What is com.android.systemui? I don't think I saw this in my usage until a couple of days ago.
Why does 31 seconds of CPU and 1 second of keep awake = almost TRIPLE the battery use of 12 minutes of screen-on time?????

It's the actual System User Interface. So most likely a combination of the rom and xposed are causing this. Also, dirty flashes of ROMs can cause this.
If you installed a new xposed module and noticed a battery drain the uninstall that module. Otherwise remove other xposed modules. You could always try a frew full wipe in recovery as well.
I have had this issue with mostly with dirty flashing which is my queue to do a clean flash. It's also possible if you restored any apps with data, like from Titanium Backup, could potentially cause this as well.

you got caught up in a lie, with buzzwords that are pushing for you to use the rom. theres no such thing as a battery saving rom. all those scripts/mods being used in the rom are just buzzwords. battery life is all dependent on how you personally use your device, how you set up your device, and your data/phone signal quality. a rom will not save you battery.

Thanks for the help, Tom. A visit to recovery to wipe caches and fix permissions and a reboot caused this -->
simms -- I do understand that. I am not really disappointed in my battery life -- and it doesn't seem to have changed much in the week that I've had the phone. But the reporting of it had, and that sort of alarmed me...

wow, your android system is high, even though only 10% battery was used. a reboot might fix that though. you might have to go through your settings and setup again, disable stuff like google location reporting/history(it wont disable your location).

I'm beginning to think the issue I'm having is in the reporting -- not actually a battery use problem. I've only had the phone a week, so my data base is small, but I haven't really seen bad battery life nor any real change in it. Even with some use and a bunch of time fiddling with the mods and stuff, I've yet to go to bed with less than 50% left. Mostly, more...
Here's the latest pics. com.android.systemui is back on top in the overview with 36% The detail page shows 39% and a whole 2 seconds of CPU. That just CAN'T be right...

Which battery graph? You mean the current usage graph I showed in the OP, from Battery Monitor Widget?
Re Bluetooth: I just leave it on, so when I step in the car it just connects to the car. No muss, no fuss, no bother.
I suppose I could try turning it off and see how much battery I save. I know with my previous phone (EVO4G) the point at which I started leaving the bluetooth on all the time didn't change my battery life to any noticeable extent.
Here's battery monitor widget current use. The EVO idled at 70 - 95 ma. This one does seem to draw a lot more at idle. I don't know what's "normal."

Not very interesting. It keeps resetting, every time I plug in to USB to transfer the screenshots to my mac for posting here. I'm not leaving it plugged in very long -- I just move the pics and unplug it. I unplugged it this morning at 7:30 AM. It's now almost seven hours later and I'm at 93%. That ain't bad. It's a gradual descent -- no big drops like the one in your post.

Mine stats those are from my nexus 7 2013, Sot of around 4 and still 55% battery left.
I just showed u for sample. A simple restart should fix as simms told
I m on stock rom with x blast tool never happened with me....u can try to use ur phone in safe mode and see...I know its a system app but u can give a try with bluetooth off. Or flash a diff rom and see

If your phone is vibrating a lot and you have extra UI elements installed this seems normal.
When you only use a small percentage of the full battery smaller drains appear large.
Bit off topic, but have you thought of using WiFi to move your files over? No messing with the wire and you could even automate the task.

CPU churning?

Every now and then my rooted Nexus 5 running stock 4.4.2 gets very slow and a CPU monitor shows the CPU going at full steam. A reboot returns things to normal.
Without knowing my way around android I'm trying to figure out what causes that. According to one of the screenshots below, daemonsu10125 seems to be one of the culprits, or Androidos itself.
Can someone suggest possible causes or ways to find out what the problem is - unless that is a known android bug. I'm attaching some screenshots taken at various times in my attempted searching. Perhaps an expert would make more sense of them than me.

are you rooted? this looks like SU acting up, maybe use another Superuser app if you are rooted. If not, I'd say get rid of this e-mail client you are running.
EDIT. Use Wakelock detector from the app store to better see what is keeping your CPU so busy.

Thank you. I'll look for wakelock

Also, do you know that stock kernel has Touch Boost enabled?
So whenever you touch screen, your CPU goes high speed to give you max performance (project butter.)

Touch boost would be fine. But I'm talking about all four cores running near maximum so the phone runs like molasses till I reboot. That can't be by design. Can it?

Nah. Get rid of the email app and go from there. Also get BBS as instructed, and please post the log here.

CPU-Z
No that is not right i have an app called CPU-Z and it moniters your phone including cpu usage and 2 of my cores are not used as they are not needed they would only activate if needed so no way should yours be running full blast

Because that's what draining the battery.. 31% usage?? It's normal if you have used your mobile only for mails all the time.. If not, there's something wrong with the app!

The email battery usage was a one time thing. Not sure what I was doing at the time. Here's a recent screenshot. It varies. Most of the time screen is the main battery user. Other times it is "Android os", which is weird.

Android OS depends on how you've set up your device... Anyways, 5% battery drain in 8 hours seems pretty good.. Not sure what's the problem here??
When you think there's a problem with excessive battery drain, use BBS or wakelock detector too see what's preventing your device from sleeping.. Screen shot of stock battery usage doesn't help.

Battery usage is pretty good. That was not my problem. My problem was that suddenly, at times, the phone would suddenly become very slow, almost unusable. It only happens intermittently and a reboot fixes it.
In trying to figure out why the slow downs happen I identified that they correlated with times when all 4 cores are running full blast. That is what I was trying to identify. Why at times the CPU is churning so much that the phone slows down. The battery charge duration is not my issue.

Looks like I'll have to bring my charger to work..

So I got the s8+ two days ago and I gotta say, I'm not that impressed with the battery, my nexus 6p was more reliable.. Just got home from work and had ~17% left with 3.5h sot. This means that when I get home from work I'll have to charge my phone for half an hour atleast before I can go out and enjoy my spare time, I can't just go out straight from work
Anyone have any pointers?
Some key notes, no wifi at work (working within the government in Sweden is retarded)
And the 4g is pretty weak.
Brightness is around 50% and I have disabled bixby and 100 other services (package disabler)
Played games for like 1h
Some browsing, no video watching
Nobody called me during the say because I'm an asshole
That's pretty much it

Two days isn't really a good test to see what the battery life will be like. Especially since you are installing apps and setting up the phone.

I suggest use a black theme to save battery, as AMOLED screens doesn't need much power producing black color.
Also in the bottom of Battery settings, there's "always sleeping apps". Add all apps here that you don't need running in the background.
Also disable mobile internet if not needed, or at least turn on data saver.

Yeah im happy both of you responded to me, I do realize that 2 days is way too soon to judge the battery, and I am not going to do so, you are both right and I did follow the advice you posted, got all the apps I don't need running in the background etc! Thanks guys, let's see if I end up with more %tomorrow after work

WOW! I wonder what's draining you so quickly? I'm getting right at 7hrs SOT with no WiFi and marginal cell service at work!

You must've disabled an app that keeps pinging the system. Try to enable all apps and go from there. You shouldn't have to disable anything. Just watch for resource hungry apps like Facebook or Snapchat

Yeah im not enjoying this.. it's been 3 hours, barely used the phone and im down to 80% already (30 min sot)
I renabled everything in package disabler again, won't be using it untill people get more comfortable and researched in the subject of matter.
4g signal is pretty bad at work though, and these idiots dont have wifi lol. (getting like 1-2 bars)

Maybe it was package disabler causing the problem, if you disable something which something else relies on it might constantly try and connect to the disabled package causing battery draining
if you do continue to have a poor experience i definitely suggest using a pure black theme, This will boost your SOT buy a few hours minimum

I did re-enable all apps within package disabler again in the morning, im at 65% now thats 5h battery usage and 1.5h SOT.
How are people getting 8-9 hours SOT... HOW
also I am using a black theme atm, it's the "high contrast" on samsung theme store
I appreciate the help

You may have a dud. I'm coming from a 6p too and I usually have about 30% batter at the end of the day when I was shutting down right before leaving. I run a dark substratum theme with brightness at 35%. I get 6hrs but I stream video and game off and on.Give it a few days and if things don't improve try a new one.

Hey man. I had this same issue when i bought my phone. Apparently my phone wasn't going into deep sleep mode. Install an app called CPU spy and you'll be able to see if you're phone isn't going into deep sleep due to an app. If your phone is going into deep sleep but you still have battery drain like that. It could be a defective device. Btw the issue I had was facebook app. I disabled it and now I'm getting at least 8:30 hours sot.

I'll look into that theme, thank you for the tip Vermicious!
I am going to install cpu spy, I do use facebook, i dont know why tbh, might actually disable it and might just use the messenger app whitch is the app i pretty much only use anyways (for social media)
I have verified that I can return the phone unlike my note 3 that I bought a couple of years ago (battery laster 4 hours first charge, wanted to return it but since i had peeled the plastic off they rejekted it lol, such dicks xD)
Other than the battery being a big off the device is absolutely incredible, I am happy I gave samsung another chance, (I had sworn to never use a samsung device again after the note3)
again, many thanks for taking your time to look into my issue!

Google App Causing severe battery drain??

Anyone else seeing this? My Google App is causing severe battery drain. It's been off the charger for 3 hours, sot is 1:52 and battery is at 85%. Google is accounting for 17.4% of drain and only active for 6 minutes and background for 12h7m. I have it set to sleep when not in use. I was watching youtube this morning for 14 minutes and it only accounted for 1.3% drain.
Yesterday it accounted for 20.3% drain and only active for 6m and background 13h 21 m. Day before that 11.5% with active 7m and background 8h 14m.
This is weird. Coming from a Pixel 4XL and didn't see this much battery drain with so little use.

Haven't noticed that on the Note 20 Ultra but on my LG V60 it was about as bad as that. I have installed Nap Time by Francisco Franco which puts the phone into a deeper doze. It's a root app but can be used without root with a few adb commands. It's one of the first apps I install on all my phones.

Has it been doing that since you got it? How long have you had it? Because usually Google is saving a lot of your stuff and creating backups in the background but you can deny background activity by going into the app and ticking the slider over to deny background activity but that might preven automatic backups and saves.

I've had it a week and a half and it's been doing that since day one when I look at history. It takes as much as 25% on some days. I cleared the cache today and hoping that may help.
It's dropped 4% since I posted and I haven't used the phone at all. That's in about 20 minutes.

That's not normal.. is there any updates to that specific app or able to tap uninstall on it to roll it back to a possible previous version?
Edit: this is the screen I'm talking about to stop background activity.
I guess it's still not showing the pictures that are being uploaded.. I'm going to talk to the owner.

I'll try rolling back any updates, but I do see when I do a general internet search that other people have had the problem with Android 10 and Samsung devices. Most have fixed it by disabling the app. But that's not an option I want to take. LOL
I've cleared cache and rebooted. I'll see if I still see a large battery drain. If so, I'll uninstall and reinstall and see if that fixes it.

By the way, do you have a ton of apps and pictures and all kinds of stuff on the phone? Because if you do the carrier's don't give very fast upload speeds and if it's trying to save a ton of data it's definitely going to take quite a while on carrier data.. I'd use a business or someone's wifi if possible so it can do it quickly.

Never tried naptime is it any good?
I have package pro and killallapps installed so would i be able to use naptime along with these?
Also is it just one click does it or do you have to do your own apps to deep sleep
Thanks

I have a lot of apps disabled and yes you can still use it, don't know anything about kilallapps though. If I charge my phone to 100% before going to bed and lay it on the table until morning in 10 hours it won't lose 5%. depending on what apps you have installed may not be quite the same. And yes it puts the phone into a deep sleep. You can have it turn bluetooth, wifi and others off while in doze

Here is how I have mine, the first two screens are on the home page and the third is from the Naptime labs.
