I was in a class that is from 7AM-11AM. The classroom has no signal whatsoever so at 7AM I put airplane mode on, didn't turn on Wifi, closed all open tasks and just for the heck of it turned off background data.
When I put all this into effect, I was at 91%. At 9AM I see that my battery went down to 81%. How is this possible? I was in airplane mode so nothing was synching or downloading, no programs were running in the background or anything at all. On my previous phone (Nexus One) under the same situation the battery would have been at 90%.
Phone Idle- 34%
Cell Standby- 30% (Time without signal 85%)
Am I missing something here? Can someone please elaborate why this went down so much for basically doing nothing.
Did you drain your battery completely the first 5 to 10 times charges, when you first got your evo? Many people claim that's how to he the maxium battery performance from your battery on any phone
Normal. I lose about 10% every 2 hours.

Yeah but I wasn't even using it and it was in Airplane mode. That can't be right
WOW... sounds like its your CPU thats still killing the battery??? You don't have it rooted or running any cutoms ROMs on it?
We SERIOUSLY need to get a UV kernel on here and underclock this thing when its asleep... So many battery drain issues.
Your issue is REALLY strange though.. I was in LA yesterday and mine didn't drop that fast for like 2 and a half hours... Very interesting......

This is bogus. Don't bother doing this. That was something that was needed back in 1999 back in the days of NiCad and NiMH batteries... It doesn't help LiIon one bit.

20 hours of battery life is pretty good. I think the record is like 62 with everything completely hacked down. I get about 4-6 in full on usage.

I understand that 20 hours of battery life is good but If I was using the device in those 2 hours I wouldn't be worried. But I wasn't, it was completely IDLE with all the radios turned off and programs killed (advanced task manager).

Deactivate any syncs you don't use. Make sure your phone is set to CDMA. See what processes your phone is running that are killing the battery and disable them.
I get about 27 hours on my battery.
I fixed the problem. I rooted 2 days ago (evening) after getting such bad battery life and I flashed Damage Control 3.0.
Today after 2 hours and 30 minutes of being under the same exact conditions as my original post (30 minutes more this time) with Airplane Mode, Wifi Off, Tasks Killed,etc I only lost 1%.
I went from 93% to 92% in 2 hrs/30 minutes which is a hell of a improvement in comparison to losing 10% in less time (2hrs) with the same exact circumstances.
I am extremely happy now. Oh and by the way, yesterday I got 14 hours of usage with this ROM which for me was unheard of before (4-5 hours)

Im getting some weird battery stuff, as well as the Android OS drain. If I restart my phone, once in a while It drops like 20-30%. i'll go from 46% to like 18%. I see the threads about slow draining, but mine seems to happen instantly sometimes (3 different times so far in a week), anyone have solutions? Got it from someone on ebay, can I still/should I RMA?
Someone posted a kernel fix in the international GSII forum, so we're either waiting for that to get ported over here or wait for samsung to release a fix. I have that same bug too. What percent r u getting on the Android OS? Mine is usually in the 60's.
Yeah I saw that thread, and I saw the 2 things causing it. Waiting for that fix I guess, hopefully it solves the big battery drops as well as the small draining. Mines pretty high, 30-50% I believe, and then cell reception takes 10-20% with LOS
That's alot better than mine. Although, I don't have that LOS problem. I'm running stock atm. Are u on a custom rom?
Running Starburst 1.5, stock was better for no LOS. But I like the customization on Starburst. Hopefully by the end of this week the kernel we be ported over.
Most likely a problem with the battery level algo and not an actual battery charge drop. It's probably showing the correct value after the reboot.
Using battery spy I was using like 12%-15% per hour, not even doing anything. Saw online that formating the SD card might help, just did, and now im using .8% per hour. The hell, something was scanning the SD card or something. Much better now, hopefully itll last 10-20 hours instead of 6 hours.
edit: so it went back up again. At .8% it will last 2 days+, but since the events keep taking the CPU, its draining it. I got it down to 4-8% by taking the SD card out. At least it will last a little longer. Cant wait for the fix, this baby will last days after.
Damn that sucks. I just formatted my card too cuz I was running out of options. Keep us updated tho.
so I think media scanner is draining, I downloaded rescan media root from android market and before I was draining at 12% per hour, but when I disable it with the app, it goes down to 5-6%. Anyone else try? Maybe thats something thats draining.
Oh btw have u tried turning off wifi? It only drained 6% after being off the charger for 9 hours. I havent touched the phone during that time span tho. Android os still in the 50s btw.

this is almost definitely correct. battery doesn't drop 15-20% because of reboot...the reading is wrong. Battery drivers have been bad on a few of the latest android phones. Just look at when your phone stays at 99% for the first 3 hrs of use each day...what, does it just get really inefficient in the afternoon because of food coma from lunch?

Trying now, seems to be charging faster too. I was mainly on wifi because cell standby was really high, keep getting LOS. But maybe I wont with wifi off now, and i'll see how battery does. ill keep you updated.
Still bad. Can only wait for the patches/fixes. 8 hours doing nothing almost. Sigh.

Hey man, I got one more tweak for u to try. I just rooted my phone w/ the latest zenomax kernel and Starburst 1.5. Download setcpu and create a profile for "screen off". Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Think I have the v3 version and 1.5 as well. I have setcpu set to 200-400 powersave. ive tried others and same. Suspend and events/0 keeping eating at the CPU. Thanks for the suggestions though.
figured i'd chime in here. i've had days where the battery was fine and days where the battery was absolute trash. it's happened on stock, and it's happened on root. but it almost always seems to coincide with LOS. the first picture is one of several instances where i've had pretty fast drain followed up by an instant dump in charge under normal use. it's strange how after the drop, it slowly works back up then levels off and drains normally. the 2nd pic is from today. i left my phone at home on accident when i went off to work, and when i returned, i had LOS and this battery stat. you can tell where i lost signal . the last pic is from yesterday while i had the phone at work all day and light use; a nice consistent drain.
FU battery drops and FML
Ok so i read all the posts in this thread and i understand theres a issue that effects the phone from even knowing what the battery % is. i had to post these though. i was at 47% then rebooted my phone. phone boots up and yehhh! woop woop 8% now mind you if you look at the graph it shows a nice constant cerve downward but steady because i was using my phone the entire time. now after the restart/batery drop of 40% i kept using the phone constantly but its funny how it took me over a hour of screen on to go from 8% to 5% !!!!! i bet to get from 5% to 1% it will take 2 more hours for sure. you can see the graph start to flatten out like its a super battery after the 40% drop because it didnt really drop to 8% !!! normally i wouldnt care since my phone battery last just as long, it just goes down really slow from 8%-1% but at 5% it auto dims screen and wont let me use my camera for the next 2-3 hours while i knock off the remaining "4%" of battery left. fml
Get Starburst v1.6. He removed DRM processes which should lower Android OS usage and thus battery draining. Plus with the LoStKernel, I haven't had any issues with losing signal since.
Also, use Titanium backup to remove running services that you don't need. I got rid of the stock email client, digital clock, media/social hub if you don't use those. They don't take up a lot of ram, but every little bit helps.
My battery life has improved after battery calibration. I suggest you calibrate if you didn't already so your battery usage graph may be more accurate. Hope this helps.
Thanks for the tips! I was wondering how you would calibrate the battery. Is it the same as wiping battery stats from CWM?
Currently using latest calk rom I get about 2 hours using my phone for browsing thr internet at home. When 3g is turned on it drains even faster.
It has always been like this. If the phone is set on idle without 3g and wifi it lasts about 10 hours.
also it takes about 3 to 4 hours to fully charge, i feel this is too long.
so any rom that might help me? is the battery faulty?

Blazer ROM
why are you using your phone to browse all day long ? use a pc or a tablet. its a phone not a desktop pc. plus put it into airplane mode and then turn wifi on, it disables the cel/data radios hence the battery last longer. If your phone takes 3-4 hours to charge from 0-100 something is wrong with it. turn if off and charge it, cuts down charging time A LOT !
That is ridiculous. But I've been using Blazer Rom for about 2 weeks now and I always get 30 hours+ battery life. I just got 3.8 and I hit over 40 hours just this weekend.
well, um, wow, those are some ... great suggestions...
you might have a bad batt, sure.
i would think it is likely something else though.
a few things off the top of my head.
is this on a "clean install"?
is there some app you have loaded that might be pinging/updating constantly? (I'm on the exact same rom, getting all day at least)
what modem are you on?
did you flash a custom kernel?
do you know how to take a screenshot of battery usage? show us what processes are eating it?

It could be a bad ROM (bad install, not the ROM itself), but don't presume that's the case.
Measuring whether the phone is draining appropriately is difficult to do when it's in active use (e.g., 2 hours of browsing) ; thus most people measure effective drain by measuring the drain rate when the phone is 'sleeping' -- though in some cases a bad app or bad install will prevent the phone from sleeping.
I would recommend charging the phone to full, leave all default radios on (GPS/Wifi/3g), and let it sit for an hour or two. If you're losing more than ~3-5%/hour, then you have a problem.
Tools you can use:
- CPU Spy - Will show you whether your phone is entering Sleep state or not
- Battery Monitor Widget Pro - will measure your mA drain rate; during sleep, you'd want it to be at least below 20mA, ideally below 10mA (note, this app requires a couple of charge/discharge cycles before its measurements are reliable).
- Better Battery Stats -- If you find your device is NOT sleeping, this will help you figure out what applications (including the kernel) may be preventing the device from sleeping.

Your point? I could kill my phone in 6 hours too, but why would I want to do that? I play games all the time when I'm out at work or just out in general and I still get over 24 hours of battery. I never use my phone when I'm at home, that's what I have my tv and computer for.
how long has it been since you flashed? Maybe it needs a few cycles to settle. Do you have any wake lock issues? get betterbatterystats app, free for xda members, to check for kernel or partial wake locks.
I'm on BlazerROM 3.7 and getting about 1% every 2 hours on idle. It took me a week to see the battery life i'm getting now. My wife is on calks 2.8.1, I don't know what shes getting but when she gets home from work, she's still around 50%. On stock, she was typically around 30% already.
how do you get betterbatterystats for free as an xda member?
I'm on blazers and i'm at 79% battery at the 7hr mark on battery.

I have seen this "mystery battery drain" problem in other threads. There is usually an app responsible. Try Watchdog, its not bad.
I also have heard that SD card or file errors can be responsible for the drain. Formatting the memory takes care of the problem. If it were me, I would format the memory, then run chkdsk (Windoze, or the equivalent in another OS) to mark bad sectors. In the case of internal memory, you will have to do that through the USB cable. Do so at your own risk, of course

The point is you walk into someones situation and act as if their usage of the device on whatever rom your on is going to produce a parallel experience. One of the biggest factors no matter the rom is screen brightness. If you spend most of your time out doors the experience is completely different even with the same usage patterns otherwise. I love screen brightness personally, haptic feedback is nice too who cares about the battery when the experience is better?
I have games on the phone, GTA III, MC2/3, Dead Space, etc. I don't actually play them. I remote into my PC, browser the web. I have a TON of apps that use the phone idle/background. I keep steam and im+ pro going. I let TEP ping GPS data every 10 minutes. Weather widget, google voice, etc. I even have Samsung Apps installed with its oh so horrible push service that apparently rapes peoples batteries... cant say it hurts at all.
Today was a day for me where my boss was around so I couldn't use the device much and when i did it meant leaving things like a remote client on because I couldn't touch it to turn it off. 52% battery was left after 12 hours so it obviously was going to survive the 16 hours I am awake, going to sleep now so it would easily last 24 hours. But the battery being Li-Ion and me actually caring about it, its going on the charger. Tomorrow could be 30 and the next day will probably be 8 hours.
As far as the topic is progressing. Check your apps and your settings. Ive had battery life so bad the phone died on the charger. Same rom, same apps slightly different setup later and I am getting good to acceptable and that constant wake this guy is probably getting is gone.
If your using a lot of push apps, you're battery becomes nothing more than a decoration, lol. Apps like aim, kik, basically all the chat ones. Games like words with friends. The more apps you have checking for updates on top of heavy usage with kill your battery fairly efficiently

Which personally was part of the issue before on my setup. I still have them going again and battery life is decent. I mean Id want 16 hours out of a phone surely whatever my day is Ill have it on a charger by bed time.
I personally usually get 12 hours or more on days Im not using it constantly, 6 to 8 if I am using it every waking second. 24+ on days off. Haven't tried blazer in particular myself yet but Calks seems manageable even for demanding use.
I've had this phone for about a month. Started off on stock, and rooted it and flashed different ROMs and kernels. I never really got good battery life with any ROM. Typically I would get around 7 to 10 hours of moderate usage.
I fully went back to stock firmware and kernel using ODIN, to flash 2.3.6. I rooted it and removed some bloatware apps. BUT, the battery life seems so bad.. it's been 2 days, I've done calibration 2 or 3 times.
Leaving my phone idle, in one spot, I lose about 4-5% an hour. 4G Data on, wifi off, 2/4 bars of signal, sync on (only gmail, google docs, contacts, calendar).
But today, I think it got worse, as shown here: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230121.png
Graph: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230126.png
Note: the data icon on top shows that it's on 3G, because I moved out of good signal area when I took the screenshots. The phone was idle in a spot with 4G getting 3-5mbps.
What's wrong with this? The phone is a month old, so I don't think it's a battery problem. I've calibrated 2-3 times since I went back to stock.
Also, don't recommend me to use Juice Defender. I use Google Voice to call and text, so I need data on all the time. And I know this phone can last over a day with data on (my friend has the same phone and it has lasted 2 days on one charge, completely stock firmware).
ALSO, when I press "Android System" on the battery history, here's a list of what it shows:

I see easily over 12 hours on a charge with my phone, and i use it heavily... 2 to 3 hours of phone time (at the least) wifi tether here and then, a lot of facebook iming and checking. Reading....
Something i noticed though. I got the phone in October or so, and the battery life started off pretty bad. I didnt do anything special, i figured it would be bad with such a massive screen. Over time though the battery improved, and now im seeing wonderful battery life. I usually unplug it at about 6:30 or so in the morning when i head to work, and yesterday at 10-something is when it started *****ing it had low battery life.
Moral of the story? Be patient, itll get better as time goes by.

Something is definitely draining your battery. As you can see your phone is awake when the screen isn't even on. It's just likely an app you downloaded or something in the background. good luck narrowing it down

2050mAh wouldn't get you to much more out of thr battery..
Only 200mAh over stock, hows this supposed to help if you have a sleep mode issue or app issue?
Bringz me back to my first statement.
Your kernel is NOT allowing deep sleep mode for whatever reason, your best bet would be make a backup
Delete data/factory reset and try it over a day.. if it works good, its an app issue, still the same. It is undoubtedly the kernel. Why pay more for maybe an hour out of your phone?

There. I said my peace
If you tried everything else try recalibrating the battery.
I have seen this happen most often when flashing new ROMs. Especially if you did not wipe your system, data, and caches before install it seems to encourage this.
To Recalibrate Battery (must have custom recovery like cwm):
Charge phone to FULL
(I highly recommend AC charger for this)
Reboot into recovery
Look for wipe battery stats (should be I'm advanced if not main menu)
Unplug phone and restart it
Now FULLY KILL THE BATTERY
(for faster results set mp3 or video on repeat and let her rip)
Fully charge one more time and done
(again I highly suggest AC adaptor)
Keep in mind if you set your CPU to Max frequency or leave a demanding app running and CPU is set to allow full usage ondemand or performance the phone will kill battery very quickly.
Same if you leave antenna on auto 4G and it is weak around you and phone is always searching it will go fast as well.

You sir, are a n00b, calibrating the battery is useless to this device and actually done automaticly.
So your post is useless and rather a waste of everyones time even reading. So thanks.
@above
Its obviously not hitting deep sleep, there's no way it can be and be draining the battery this quick.
@OP
As suggested above use cpuspy to check on the cpu when idle,
Sleep mode should kick in within 30sec to a minute.
Also chek my reply a few posts up and follow steps there..
Ignore Realn00b's post
Again:
@Realn00b
Please take the time to read up on batterystats.bin and find out what its for,
You don't need cwm to delete, just root explorer.. its in:
Data/system/batterystats.bin
Also, the entire basis of this is stupidity and was takin way out of context.
Batterystats is used to cache the active information of running applications (uptime/cpu usage, etc. NOT battery percents)
And should only be deleted under very very rare occasions (effecting above)
Your battery percent, is actually the mAh
Your system collects the information from a chip on the battery, among the information read, max mAh and current mAh.
The device then calculates from these the value we know as the percent.
Meaning, no device with a lithium ion battery stores charge information for the battery, making the entire purpose of your post for this, or ANY device not only useless, but also a little pathetic considering you would actually try to post a tip on something you are obviously completely uneducated about.
Please don't provide tips unless you are 100% sure of the situation and are actually educated on the material. Thanks

2050mAh wouldn't get you to much more out of thr battery..
Only 200mAh over stock, hows this supposed to help if you have a sleep mode issue or app issue?
Bringz me back to my first statement.
Your kernel is NOT allowing deep sleep mode for whatever reason, your best bet would be make a backup
Delete data/factory reset and try it over a day.. if it works good, its an app issue, still the same. It is undoubtedly the kernel. Why pay more for maybe an hour out of your phone?
Run some actual tests to clarify the issue first..

I originally purchased it for two reasons:
1. For long trips or for when I'll be gaming a lot
2. It had no reviews, so I figured I should buy it and test it. It's cheap anyways, $11.
Also, I'm on stock kernel. Everything stock + rooted.
I just did a re-flash with ODIN, so it has all the bloatware back on. I rooted and installed most of the main apps I use (facebook, aim, xda, google apps, games, basic things).
Currently I have sync on for Google contacts, calendar, and gmail. Facebook syncs with existing google contacts. T-Mobile contact sync off. Dropbox auto uploads camera photos on wifi only (I rarely take photos).
It's charging right now, at 50%. I might not have time to leave it idle today, so I could try in the morning if I have time.

Yea your right that is a good price.. is it same size as stock and have NFC? can you post link?
Thanks.
And please excuse realn00b up there..
He didn't know wat he was talking about.. read my post below it if you want an explanation.
Take a look at the safe to remove apps list aswell I'll see if I can find it on google pages for you. I definitely recommend
Deleting unndeeded applications and even replace stock with third party where applicable.

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.
