battery and rom help

We I am rooted and have tried several different 2.2 roms and kernals with no luck on battery life I can get 16-18 hours out of a charge with minimal use. Does anyone have any suggestions what i can do. Is there a go to rom and kernal? with all of the 2.1 roms i would get a couple days out of a charge. All i really want is to go at least a day without recharging, it sucks when im out and my phone is flashing red around midnight and ive barely used the phone all day.?!

16-18 hours? Jesus, I'm getting maybe 8-10. You should feel lucky.

check out Ava V9 + Netarchy's aggressive undervolting kernel. I swear thats the best combo ever. Battery life gets better daily with it, right now, its "meh" but it feels like its improving. First time i flashed it, my phone wasnt sleeping and it was dying while the screen was off, but wasnt losing any power with the screen on. So i let it die, charged it up to full, now it hardly loses power with screen on and off.
I'm only on my second day with it though, but its pretty amazing. And during the weekdays i use my phone heavy. Constant texting + music + twitter (3min refresh) + autosync + angry birds + wordfeud + space physics + browsing. I use my phone instead of my laptop, so thats why i have all of that going on, so from 6am till noon, i only have the screen off probably for a total of 30 minutes, everything i listed above is being used and it makes it to 60% battery left. As soon as my battery hits 20% it takes forever to drop, 10% takes even longer.
tl;dr Ava v9 + netarchy universal aggressive undervolting is the bees knees. try it out, not promising the same results taht i've gotten, but its always worth a shot
Edit: Also OC'd to 1.22GHz

Yeah but how much do u use it, on an average day i might send 20 texts and talk on the phone for 20 minutes and check fantasy football for a few minutes, if i even try to play games its like each minute of usage correlates to a 1% off my battery, gps off bluetooth off no 4g occasional wifi here and there and i even turn off mobile network which helps but i just feel like the amount i use the phone it should last longer

Since my last post I've tried my best to mimic your usage (i went way overboard on the texting, but thats good in this case). For the game, i chose to play Angry Birds for about 30 minutes. I also played a sht ton of WordFeud, since I cant go a day without dumping a lot of my time into that game. I browsed around on my browser and even downloaded some crap. Had WiFi and 3g on for most of the time.
So far im at 47%. I started at about 2pm and it's 2am now. Im going to sleep at 2am right now so there will be that idle time.
Edit: Just now woke up and I'm at 42%. Battery Indicator indicates that my phone has been on for 19 hours so far. Ava V9 + Netarchy's universal kernel may be the set up for you.

well ive had it on for only an hour so far so good... thank you for your time

No problem right now im at 5%...24 hours unplugged and 12 hours of wake time. Im beginning to think this is the best sense rom/kernel combo.

I don't really know what the problem is :/
Can you not find a charger within 16-18 hours?
Don't sweat the small stuff.

16 hours is good, why not just plug it in when you're sleeping?
I can go a good 24-36 hours on a charge and I'm using the phone 100% original.

I charge it all the time, before i leave work, when i sleep, in the car if i have to, it just sucks the few times i dont get a chance to charge the phone and im out with friends and i cant even use the phone because its like once the screen is on its time for rapid battery drain. Last night i lost 15% in a 7 hour span of not using the phone once. I even have set cpu set to the lowest setting when the screen is off?

Thats what was happening to me at first. With the screen off I lost all the power but with it on, it was all good. Confused me, so i went into recovery and just wiped cache and dalvik...dont think it did much, but i just let the phone die. The next day, it seemed better, the day after that, a lot better. There are some kernels where you barely lose anything while the phone is sleeping...but with this one, its like the opposite for some reason. Which is kind of a good thing and a bad thing at the same time.

I use Ava. I have a battery thread in the general forum.

[Q] Instant battery drops

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.

These are my overnight stats when I was sleeping. It's usually worse when wifi is on.

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?

Stellar Battery life!

I am just wondering if it was because when I purchased it I charged it from it being completely dead to full.
Then using it for a few hours. recharged it from 59 percent back again to full and left it to charge even though it said it was full.
Btw I havent rooted just the stock rom. And I can get through two days with moderate use and still have 10 percent. I have no issue with build or software.
I am pondering whether to upgrade to 1.29 when it is released for my network because I have no issues at all.
I had a small glitch when my phone woke up multiple times from scratch but it was software that caused it since uninstalling it. it hasnt occured since
base band 1.1204.103.14
build number 1.28.161.9 cl5622 release keys
browserkit webkit/534.30

What screen time? I can get 2-7 days if I only makes calls on 2g for example.

Thats impressive is yours rooted?
I get over 5 hours screen time easily

That is a dream for me at the moment, I can barely scrape 3.5 hours if I want it to last 10-12 hours throughout the day!!!!

What is your brightness setting? Also do you play any games?
To get 5hrs is extremely impressive. I once did a test by have the phone sitting idle in airplane mode with brightness set to 50%, and the phone lasted 7 hrs 45 mins before the battery died. So only 1/3 drop in screen on-time with Tegra and data usage included is great result.

Based on your screenshot, it looks like you have data and wifi turned off. Is this the case? Because most people have 3G/wifi on the whole time when they are discussing battery life.

There is like 1000 different things that affect batt life.
The two biggest battery drainers are the screen and the mobile data.
Especially if u are in a location with low signal (either it is 3g or 2g).
I have my mobile data / wifi ON at all times and I average about 20 hours with about 2 hours screen on and TONS of accounts syncing (friendcaster push, twitter every 2 hours, gmail push, google contacts, calendar push, facebook calendar, whatsapp, viber, weather, ebuddy u name it ) so I guess it is alright.
Now with mobile data off I believe I could easily get the battery life the OP has reported but that's not really the point is it?

Wow you guys have amazing battery life. Makes me think my phones faulty haha

I dont get it.. I got the phone 3 days ago, but if Im lucky, the phone lasts for maybe 6-7 hours?
It gets extremely hot when used in couple of minutes, and its like the battery is drained by something hidden.
On a night it loses about 6-7% in 6-8 hours of standby with data etc turned off
I have turned push, sync, NFC, smart screen and all that "smart" stuff off.. so I have no idea bout what drains the battery. Even the screen is on 50% and auto -_-
I have the korean version (I think?) the european version - bought in Denmaek, stock. Not rooted or anything - but is it possible to root the EU/KR edition or is it only for the Canada/Sprint edition?

Same for me. Hes obviously not using hes phone much and not on LTE.
The battery life of G on LTE is really terrible.
By the way mo on arent hot last days, probably they fixed it.
Web via LTE eats like 15%-20% per hour, reading a book on small bright is 3%-4% per hour

Is there any way to tunr of LTE/4G then? I'd rather have good battery and like 20mbit than a few hours battery and 45-50mbit download speed .. :laugh:

Battery life is consistently around 11.5-13 hrs with moderate to heavy usage.

My battery is crap too sometimes is ok ..
but it is just screen what drains .. and + if u browsing internet and u have flash enabled it is big drainer added .. needs more cpu power..
if u put mobile on eco mode turn down screen to 25%-30% turn all radios off u should be fine
download apps like battery calibration . or battery stats or juice defender

I'm really not an expert at this. I have also just opened my Optimus G, so I can't share my personal experience with this phone. However, the battery of my Lumia 920 needed around a week to function properly. The first three days I got heating and drain, almost 10% per hour, but now the phone lasts easily for two days with light usage. I was looking everywhere on different forums for hidden factors draining the battery, until I found a comment, where someone described this phenomenon: he said that a battery needs around 12 full cycles of drain and full recharge before optimal performance can be obtained. So from now on I will be more patient.
Then again, I'm new here, so other opinions are welcome.

eeemm that is not true i had phones over years and batt been always same..
it is all about usage ..
jut do test charge it fully and dont do nothing with it just ocasional phone calls and sms's and ull see then..

For me on jb v03 I get around 18-19 hours with around 3 hours screen time, but agree its all about usage.
I mean if you leave your phone off most of the day with your wifi and data turned off it will drain very slowly..
I find the biggest drain is always screen, cellular connection especially when you have poor signal, and wakelocks.

I had same xperience with my iPhone 5 so I hope its the same with my LG.
But for know I've installed JuiceDefender and disabled LTE (HSDAP+ i fast enough for my needs on the phone anyway)

exactly this is my problem ..
we traveling to the places while am in work and there are areas where is poor signal or no signal that means phone automaticaly boost its signal which is very big drain and if your mobile has no signal at all and u obviously set to automatic search it searching searching and draining hell lot!

this is true as well 4g signal is even stronger signal as previous 2g 3g drains so much plus when u surfing on the net!
when 4g will be standard the manufs will have to make new generation of batteries to stay last longer o LTE..

Phone idle refers to the amount of battery cell radios are using up when the phone is sleeping. I would recommend moving to an area with better reception and disabling data when unneeded.

Data is disabled (and wifi).

battery life is fantastic, i get roughly 5 hours on screen time, when i finish work i have 70 - 80% battery with 1.5 hours screen time

My battery life on CM.
Disappointed kinda, expected great improvement compared to stock rom

After few weeks of heavy usage, I am noticing the battery performance to improve considerably, I'm running stock 4.1.2. V10D

Battery Reducing Quickly?

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)

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

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.

Thanks, I think I am seeing a bit better today after having it for 4 days or so now? Ill follow the above quote about calibration and go from there.

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?

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.
