I have been getting terrible battery life since I mistakenly reset the battery statistics in recovery.
I have recalibrated my battery, but I am only getting like 8 hours.
What can I use to see what is using the battery? I think there is something in spare parts, but I am not sure what to look at there.
Any apps or methods would help me determine what is chewing it up is much appreciated.

It could just be that your phone is incorrectly reporting how much battery life you have since you reset them, and a couple days of usage will just allow it to gather more data and get more accurate.
But if there is an errant app draining your battery, a combination of spare parts and an app called SystemPanel should allow you to narrow it down to what's causing problems.
Plug your phone in for a minute, then unplug it, let the phone sit with the screen off for 25 minutes or so, then go to spare parts->Battery History, then choose other usage and since last unplugged. The running % should be close to the screen on %. If the running % is way higher than screen on, that means something is running while your screen is off.
I paid for the full version of systempanel for the system monitoring feature, but i think you can use the free version to just check which apps are running. Things like google voice should say running, but just about everything else should say background. If you have an app that you downloaded, but haven't been using in a while saying service, there's a good chance that's what's causing your phone to run the batteries out. Garbage apps like Grooveshark (which I still use because I can't live without grooveshark) will run even after you could have sworn you closed out of them.
The paid version of systempanel makes things easier because you can set it to monitor, then come back and look at what apps have been using cpu cycles even when the phone isn't being used. The system processes are always going to use cpu cycles, but apps like Swype will (or did at one point) keep the phone from properly sleeping, and you can tell by all the cpu they're using even when the screen is off.
Ah, that is a good point. 2 apps that I did change were I installed Tiger Text (neat app but rather sure that drains the juice) and I put on a different version of swype.
Thanks for the tips, I will run with that.
More reading I am doing I think the mistake I made, is that I reset my battery statistics when my battery was only half full.
I put in a full battery, reset statistics, and will let it drain, that should calibrate the phone correctly.
Thanks for the tips though, I will keep those in mind.
Battery consumption is going trough the roof lately..
Can someone tell me if it is normal to go from 56% to 28% in an hour of surfing and listening to music? (see screenshots) Screen brightness is 10% and just surfing, no downloading from the market etcetera..
I think it's unacceptable.. Took my phone from the charger 7:30 this morning, i charged it at work from 50 to 60% in the afternoon.
Current charge is 17%.
I already changed my ROM (clear cache, dalvik, storage) and radio but it doesn't seem to help at all...
I ordered a replacement battery for only 10 euro at ebay so i hope it will solve the issue..
Also, is there a known fix for the 90% charge on wakeup? It's rather annoying.
Yep thats 3G for you.. I've just been doing the same fir about 10 and already a 15% drop.. at least yiu can change the battery unlike the iPhone..

That's ridiculous.. Are you telling me it's normal to drop a percent per minute when actually using the device? (happened to me the other day)
Yeah I hear you. This phone has absolutely pathetic battery life. Even worse than an iPhone! Even using SetCPU to underclock it has little effect.
Just 10 minutes after unplugging it from the charger its at 94%. Another 10 minutes later its at 89.
Disturbing.
If you are sure you don't have an app running in the background, or a badly coded app draining your battery, I'd try THIS. I get around 48 hours of medium use on a full charge.
Calibrating the battery made a massive difference to me.
I forgot to mention that in fact i did calibrate my battery. Twice. Already 6% down in 10 minutes as we speak.

Im not trying to be rude but im assuming you have checked all your settings & applications for wakelock bugs and syncing related stuff?
You should roughly have ~1% per hour consumption when idling(screen off).
Try typing *#*#INFO#*#* and see battery history for any abnormalities, like way higher "running" % than "screen on" %. They should be pretty much equal.

Yes i checked all those things numerous times also no abnormalities in applications sucking up all the juice.
I think we can conclude the battery(consumption) just sucks monkey balls.
When your battery is fully charged go to phone and type the following. *#*#4636#*#* then tap battery information. It should say battery health good, and then Battery voltage. What doe that read?
I'd also try calibrating the battery again, following the instructions to the letter. If all else fails I'd try a factory reset and run it at stock for a while to test and ensure you don't have a rogue app.
One thing I'd say about your cheap replacement battery. They are never going to be nearly as good as an original, as they are mostly poorly made and deliberately wrongly labelled to make them look like they are high powered, and at worst can be dangerous. Just be careful with that one.
I really can't understand why you would have such poor battery life. I'm happilly getting at least 48 hours with mine. I have wifi and data enabled all the time, use it a lot for twitter, make a few calls, and send texts.
Anyway, good luck and let me know how you get on.

Cheers for your reply,
I checked using *#*#4636#*#* and nothing out of the ordinary to be honest.
When fully charged it's around 4100mV so that should be ok as well.
About the cheap battery, it's from E-cell in the UK and my previous purchases were of good quality. So will see if it's crap or not
Having the same issue as you. Bought my phone 5 days back and I calibrated the battery too. No sneaky app trying to drain the battery.
Will wait for couple of days and then as suggested will reset the phone to factory settings and then check.
when i first installed the latest release i had amazing battery life. Now im at 70% an hour an a half after i unplug it and it prpbably wobt last me another 5 hours. I dont think i have any apps draining the battery. Ive wiped battery stats. What's going on?

If you used 30% in just over an hour, either you used it too much, or there is some app/process draining the battery. Download Spare Parts, go to Partial Wake Usage in the Battery History. See if anything stands out. If not, re-wipe everything and re-flash the rom. I'm running the same rom, and can go at least 3 days without charging.
battery usage history force closes spare parts...
Same here, it force closes when I look tap history. However I stopped using the changing photos lockscreen and my battery life seems to be improving.
World peace with no regard for human life.
standard wallpaper, and wallpaper lockscreen. I re-flashed the rom.
I had the same problem with an extended battery, only it would charge to 80%, then it power itself down and the battery would die. I took it to Sprint, they were awesome, the tech said that the modified scripting from the 3.0 Sense Roms is causing this problem on some phones, especially with extended batteries, rather flash my phone to stock, he gave me a differnt battery, wiped dalvik, said he did acouple things to it, and advised me to run a different ROM and see if that helps, preferrably a hybrid that the battery scripts have not been modified. I think alot of it was somewhat bs, but my phone holds a charge now, I am currently looking for a different rom...
It started out draining real fast, then it wouldnt charge after a few days
Title. H810 no root.
I'm aware the battery life on this one is not really good. That in mind.
-Example, (nothing running on background, everything but wifi off) using it normally until 14%. Pushed sleep button.
-Turn screen on like 5 mins after and it was 15%, used it a bit then again screen off.
-Turned screen on about 6 minutes later and it was 5%.
-Drained it to supposedly 1% then phone turned itself off.
-Turned phone on again and it was 2% and stayed like that for 10 mins while scrolling twitter with 30% brightness, until it turned itself off again and this time battery is to low to turn on.
Tried factory reset, draining till absolute 0% then 100% multiple times but so far nothing works.
Battery's health is good and factory original, no water, no heavy drops.
Let's say i root it (as far as i know its possible in all models), question:
Is there a way to push battery stats to make battery readings accurate?
Or what do you suggest? thanks.

Hi,
What you have is normal.
My owen device jumps frpn 12% to 15% after heavy and log use, thats normal, cause battery is cooling down/pre-ucomputed Energy is not consumed and Battery is calculated new.
The other Jump from 15 to 5 thats somthing you should watch closer. did that happen often?
all in all I have a sugestion but answer this first.
How old is Battery and usage time? (heavy or Soft? SOT? and so one)
Battery readings denpend on the Kernel. You are Stock i think?
Titan Kernel gave me awesome Display Sdreen on Times but battery is jumping too.

Thanks for replying!
Well thats one solved, it wasnt a sudden jump but rather a few minutes discharge doing nothing at all.
Battery is as old as the phone, 2015 and usage, i dont know for sure since it's an import US carrier phone sold to me locally, seems like it was a test phone like the ones you can try at stores. I would say battery use isnt any different than it would be in a daily usage and even if not, would be very rare for a li-ion battery to degrade in such a small amount of time. Gonna ask the seller.
Another thing i notice is very fast battery drain while playing music. I listen to music from home to work, like a 1 hour trip and when i got of home with 81% when i get to my job im at 68%.
And yeah stock everything with android 6.0, as i said currently not even rooted.

Sounds as if the Battery has some Altered Issues. How Often do you charge?
with Music You meen Mp3 or stream? (stream drain battery much faster)
Try custom Rom and titan kernel if u dont need stock services, otherwise rootand use greenify or other.
on Stock i Had SoT of 2 hours max. now i am back to 3 Hoeurs (i´m heavy user some days...)

Already using greenify. Charging 2 times a day, 1 before going to work, 1 when i come back, plugged while using it.
MP3 from stock music app, since i read somewhere a 3rd party music app caused an user a battery drain-
H810 has locked bootloader, do you know any flash tool?

Greenify is much better with Root
first you must unlock your Bootloader.
there are 2 Otions at the moment. Official (don´t know if possible for H810) and USU by @steadfasterX

Just by a new battery. Original battery can be found for about 8$ at least here in Sweden..
I believe this is normal.
My H815 had it with both the original and a new battery. It used to be really bad when you charged it to 100%, restarted and it would drop immediately to 80%.
Also, especially on stock LG stuff (the graph on custom ROMs seems to be smoothed out), the battery graph was a mess of random spikes and dips
Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help
If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.

Best way to go is using normal charge an never let the battery drop below 20% forget about trying to maintain certain range (60-80), it will just drive you crazy

If I put my iPad mini to sleep at 100%, I wake up the next morning with 100%. Maybe 99. But usually 100.
That's not the norm, and it's not perfect apples to apples, but it is possible.
Also, 2 days of standby with zero use is not unusual, but definitely not "crazy good".

Wow that is unusual. Do a search for "sleeping apps" in setting and add all the apps you don't need running in the back ground. Also in device care > battery you can see what app is using your battery.

So besides that little fight you had with the other forum member (lol) I appreciate your comment. But there seems to be back and forth, one other person says its good, another says its not. (the one I quoted below). Just seems weird to me that with no open or running apps and just the always on display running that it went down in an hour in 2%. Searching around, people saying losing 1% In an hour with the same set up, no running apps with AOD is bad. I kind of agree since its not truly in use. But unfortunately I cannot find any battery standby tests from Samsung or anyone else to confirm it.

I agree with you more honestly that it shouldn't be going down that fast in an hour with just the AOD running. I didn't have any apps running once it 100%, I was on it while charing it to around 50% but then once I knew I was putting it down for a while I ran the optimization and had the phone kill all the apps. When I saw it go down the 2% I did check out the apps using the battery and the AOD was the only thing listed. Maybe I didn't charge to a full 100%? even though it said 100%... Ill check it out tomorrow once I charge it fully again, today I was charging it up and down most of the day sadly. I try and keep most apps from not running in the background, some I do need though like for my IoT devices needing to know my location, I have yet to change that to just using LTE as my location GPS, but that was not on last night all. Ill try out the sleeping apps though, I didn't know there was a setting for that. Thanks again
AOD typically consumes 1%~2% in my past note devices(7,8,9)

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.
However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.
Reporting my battery life. I guess this is truly an all day device.
Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

In an hour? Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use.

This is useful, thank you. Never knew not discharging device is the way to go but we all learn new things every day. I'm at 65% right now, when waking up at 6am with 95%. Wireless android auto for about an hour, plus okay-ish use. Ill make sure to charge it up to around 80% tonight.

Over 8 hours screen time is great, best I've gotten so far is 7.5 hours
I just wanted to throw my two cents in here... My battery life is pretty terrible in comparison to my S10+. Trying to find a rogue app of some sort but I just hit 1% with 12 hours off the charger. Keep in mind that is not 12 hours of use. In fact I used it for about an hour of total screen time today.

Yeah I came from an S10+ and noticed my battery on the N10+ was pretty bad in comparison.
I did restore everything from my S10+ though, not a clean install of everything.
Wonder if that may be causing issues.
Is everyone having problems on Verizon?
Quote " Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use."
Unless you put it in airplane mode, your phone will keep connected to cell tower (or wifi if you have wifi calling) otherwise you won't receive calls and messages, so there is no such thing as phone with no use, and if you have weak signal or some interference your battery usage can increase drastically even in standby because the cell radio will try to connect at full transmit power. And then you have all those programs running in the background, God knows what they're doing. As others suggested disable programs you don't use, also you can force close programs that you don't use often. When I had my older Note rooted, I optimized it so well it would run 2% down per 8 hrs overnight, but it took some effort. Biggest problem is to know what to disable without loosing functionality for stuff you need. Give it some time for people to learn more about new phone. BTW my 3 day old phone has 435 apps and services installed and most of them I have no idea what they do.
