After 8.5 hrs of sleep I woke up to only 77% battery and when I went to bed it was at 100%... so with ZERO use of the phone it dropped 23%.. seems like a lot to me but is this normal for everyone? I'm running DJ05, Superclean .7, the stable version of geekniks kernel..
If I don't set airplane mode when I go to sleep at night, after 8 hours I will have lost anywhere from 20-30% of my battery. I have terrible coverage at my place, so that is the reason that is causing it. It's not nearly as bad if I turn off sync, but still drops >10%. In airplane mode though, I lost 2-3% over 8 hours last night.
I'm having the same problem, even at work if I take my phone off at full charge and just let it sit, 3hrs later its down 20%. and that's with me not touching it. I'm running the same thing
I turn auto-sync off at night and go to bed with 97% and wake up with 94%. I had battery issues with the xda app before though SEE HERE. No one else seems to have noticed this and it even contiued into DJ05. Might be something to look into or you might discover what is killing you.
good day.
Wipe the battery stats after flashing a kernel or rom. But before you do that, charge the phone to 100%. After wiping battery stats, disconnect the charger and use the phone regularly and let it die out. Then charge it back to 100%, not turning it on. This is a battery calibration, and I always do this after flashing a kernel. I've had instances where I've had the battery go down 1% during the night after doing this.

Eh, it's a bit surprising that display took up 40% while your phone was supposedly asleep; maybe something woke it up during the night and turned the screen on.
That's about what I get over night, but i'm using a not using a custom kernel.
try a different kernel
after trying every kernel available, ive ended up with jt's 11/29 kernel being the absolute best on battery life. im getting around 30 hours with normal use, all other kernels seem to last 12-14 on my phone.
I turned off auto sync and only lost 10%.. So that helped, I also just installed a new kernel so we well see how that runs too..

did the battery calibration and I have had the phone off the charger and using it for about an hour now and it only dropped one percent so far..usually it would be like 15 percent

Sent from my SCH-I500 using XDA App
One improvement I have noticed in the battery is it cut off about 1/3 of the time to get a charge.. In about 2 hours I went from 23% to 85% (with the phone running) and there is no way I would have been able to do that when I was running DI01.. IDK if it has anything to do with with the ROM, Kernel, or the fact that I'm on DJ05 but ever since I updated my charge time was cut by 1/3..
Hi there,
as you can see at the screenshot, there is about 3 to 6 Percent CPU Activity, no Device usage and the Battery drained from 100 down to 70% over night. I tried it with
1)Battery Doc (cycle charge)
2)Delete the battery history, and did this
1.Turn your device ON and Charge the device for 8 hours or more
2.Unplug the device and Turn the phone OFF and charge for 1 hour
3.Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for one hour
it looks like that this is normal, right ?
Thanks for your help
what is your time without service? Settings > About Phone > Battery Use > Cell Standby
Thx for the quick response, it is 37%. "Witout service" means, the phone tries to find a signal, or some kind of "sleep mode" ?

It means that it's trying to find a signal. The more it tries to find a signal, the more the battery drains. Try putting it into airplane mode at night, probably will only have a few % lost on the battery then.
Actually it won't matter if you use a custom rom or kernel, smartphone these days will lose battery like crazy if you use heavy net data. I have DX and Droid2, they are the same way with froyo.
Also in case those of who didn't know, whenever you flash a rom, you automatically wipe your battery stats and others.
You definitely shouldn't wipe battery stats when you are on the midway. You should wipe either at nearly dying or completely full. However, wiping battery only "recalibrates," it does not increase the actual battery juice.
Different ROMs/kernels can help you minimize the battery drain as much as possible though by limiting how much is used by the cpu or background apps accessing the net.

Actually no. Different roms have all the same basic data usage, basic google auto-sync. Roms can't control what or how much data will be used by an app. Kernels also can't control how much net data will be utilized. Kernels can shutoff apps based on complier/lowmemkiller fix but that is based on the memory status, not net data usage.
What is the app's name for the battery usage percentage?

This is by far my favorite Rom yet but I'm having battery issues that I haven't had before. I unplugged my phone last night at 100% and when i woke up 5 hours later my battery was at 68% normally it would only drop about 10% or less in 5 hours. any ideas? I have all new radios and wimax and such.
Is your phone sleeping?
Sent from my PC36100 using XDA App
Once we get a new custom kernel, it should remedy the battery issues on that ROM.
We just have to wait for HTC to release the source for the latest kernel.
OK stupid question how do I know if my phone is sleeping ?
At 7am I reset battery stats and put in a 100% battery (charged on an external charger)
Now (11:15) I am at 69% I expect this to get better once the batt stats are done.
I have new radios and the kernel for the ROM.
stock battery. i dont think my phone is sleeping.
If you have mobile data on, your battery will drain a lot faster, especially while we're all stuck with the stock kernel
No battery problems here. Altho it is the stock Kernel, i can easily use my phone for a full day with several calls, a bit of gaming and youtube (3G) while in the pooper and have 50-60% remaining in the evening
Try to reduce app sync frequency (you don't need that when in bed really..), LED notifications
No juice defender, or taskiller, or extended battery- just using setCPU with "onDemand" governor
That's about where mine is, too. I'm used to my SBC setup though, where I'd be at 85% by the end of the day.
You should not be losing that much battery over night. I generally only lose 2-3%. Have you checked your battery usage? Post a screen shot of it.
It looks like this
http://smartphoneblogging.com/wp-co...ngerbread_battery_consumption_app_graphic.png
You can see when your phone is awake vs screen off. And if you click on the apps in the list, it will tell you how long that app kept the phone awake,
So when can we expect a custom kernel. i use set cpu with ondemand also no juice defender or app killers here either.

So something is waking up your device then. You don't have the wake lock issue. Do you use google latitude? That is a huge battery hog
yes i do use latitude all my sync like facebook and weather are set to 1 hour but have always been and never had this problem before.

Try it w/o latitude on. I only drop 1-2 maybe 3% through the night once i turned those off. I have my facebook contacts set to sync once a day (don't really need more than that unless you add friends a lot or they update their picture frequently)
Weather I have set to 3 hours, but there is an option to update on device wake..so that isn't an issue either.
Give it a try and see if it helps.
Also if you haven't calibrated your battery, charge your phone to 100%, boot to recovery and wipe battery stats, drain battery til phone shuts off and then charge phone back to 100%. I can usually get about 24 hours of moderate use out of my phone.
ok will try those. i did battery wipe just yesterday
just click the link in my signature for some really good battery tips
OK guys so nothing I done helped my battery life while sleeping so I wiped wiped and wiped again and reflashed twice set everything back up and now my phone sleeps again. These roms can be funny like that sometimes I guess. Any thoughts on that?
Sent from my PC36100 using XDA Premium App
Roms, especially ones that are ports, can be weird like that sometimes. If a couple of wipes and a re-flash did the trick then I'd say that's great.
If not, then it's just bad luck I guess. Hopefully the kernel source will come out in the next few weeks and we'll be able to get kernels that can squeeze out better battery life.
I've unlocked and am running Ken's Alien ROM and so far I really like this. Im an international user on orange uk, so I use faux123's kernel for Oc and ram fix. But there is one caveat. I have really rubbish battery life. I did all the stuff (charge to 100% from 0% wipe stats, calibrate). The fact is, I left it on, for ten hours. The display was on for about 2. No usage. When I returned the battery was 30%, with phone idle consuming 30%. Newer radio needed? What can I do? My baseband is N_01.95.00R .
I've heard good things about the newest AT&T radio for battery. How can I flash this to an international ATRIX?
Help appreciated
Edit : phone idle consumed 40% :O
I have the exact same issue. Unfortunately, all that I can say is that changing neither kernel, radio or rom did fix this issue. I had some improvements when I followed this topic and flashed back my stock kernel (with no OC), but still very far from what I would consider a decent battery lifetime (10h with 3g + email and twitter sync and screen off)
Some users have tried and it worked well from them. I'm on the team that didn't work ): But you could give it a shot
Calibrate your battery. Charge to 100% wipe battery stats. Then discharge to shut off. Then charge to 100% again.

I've done all that stuff, but it doesn't help IMHO. (at least it didn't do anything for me)
Only 2 real fixes that have worked for me are these:
1. Freeze unnecessarily apps with Titanium Backup (use "System panel" from the Market to find out what keeps constantly running/popping up in the background that you don't need)
AND
2. Turn off Automatic Sync, and get in the habit of doing that stuff manually all at once.
@2. I use to sync in the worst signal areas, and that drained the **** out of my battery. Sync/get your updates manually in strong signal areas whenever possible...
New radio from the fruitcakes thread and the latest faux123 kernel seemed to kill that bug.
I sold my atrix to my less then nerdy friend and I just fixed that bug for him yesterday. Same deal tho...

I noticed from X2 battery (I think) every minute or two the phone constantly checks for either cell or data signal. I can let my iphone 4 sit on the counter all day and it might use 1-2% but my atrix drops 5% in an hour without touching it. No calibration or battery fix will help. Even CM7 uses it fairly quickly. Im running Alien 4 with max battery saver and gps and auto sync disabled...it should last for a full day with heavy usage.
Alien 4 w/theme, faux123 kernel, everything at stock settings for this rom, nothing frozen, and I am sitting at 1 day and 13 hours with 28% left, mostly idle, but an hour long call and bit of game playing.
If you are getting something on the order of just a few hours then your phone or battery must be bad. I am doing nothing to extend the battery life other then using the default settings.
The phone should get 2 days sitting on the counter..LOL Of all the phones I've had and iPhones I've jailbroken, there is definately something wrong with the Motorola or Android software running on this phone. I've never had to worry about calibrating or battery fixes. This is just my honest opinion. I've had 2 ROMs in all the ones I've flashed that had good battery life and I think it was a coincedence that maybe something didn't load right or got deleted by accident.

Most iphone users need to charge at LEAST once a day. A lot of them charge more than once. I can sometimes get 2 days usage from my Atrix, with heavy texting, some calls, and some games - which is pretty damn good.
Maybe your battery is the issue. not all Atrix are created equal and not all batteries function the same
When you go into settings>running apps, does your free and used ram add up to over 800? Mine used to and now it doesn't. It adds up to like 750....I always thought it would add up to mid to upper 800's. It also could be the battery but I was pointing out that I have left my wife's Iphone 4 and my atrix on the counter all day (neither one got used) and my atrix was down in the 70% range and her phone was at 96%. I'm just thinking something is running or consuming the battery. I've used fastboot to do all wipes and still seem to be having an issue.... I also flash ROMs every few days so maybe the battery calibration doesn't have time to really calibrate. I'll pick a combo I like and keeep it for a few days and see if I notice a better battery life.
How long has it been since you've flashed a ROM? It usually takes a few days for it to settle back in and provide decent battery life (at least from my experience). My phone right now has been on for a little over 7 hours and is at about 55% with Display using up 60% of the battery (3hrs on). This is with the Alien v4 and Faux's latest kernel. The first few days after flashing a ROM my phone would usually only last about 7 hours.
i get 2-3 days on stand by. and about 6-8 hours of straight use. 3-5 if i'm using mobile broadband.
1: keep gps and data off (background data is almost irrelevant.)
2: use green power
3: use a task manager to close applications that you are not using. (be sure you can add "ignore" exceptions otherwise get a different manager. anyone who says not to use a task manager is a ****ing punk hipster ***** fag who's irreparable damage to the geeks good name will not go unpunished)
4: do the "wipe battery stats" bit after every flash (100% charge, wipe stats, full discharge)
5: is to install a custom kernel and use SetCPU to underclock to 312 while the screen is off..
most importantly: use your head. if you stream 1080p using mobile broadband for 2 hours your battery is dead.
I flash ROMs every few days but I call BS on the whole "Battery Calibration" thing. If my battery is showing 4200mv...it's full. It will die faster the more processes the phone does so my point it....whether I flash a rom every day it shouldn't matter, if the phone (After I set up and install whetever apps) gets unplugged, something drains the battery. Maybe the infra red sensor is always on, or a process is always starting and ending, who knows but the battery cannot be calibrated, the phone might need to be calibrated to read the correct voltage but batteries don't hold memory unlike the old NiCD rechargables from years ago.
When you flash a rom the battery stats get messed up. Based on what I know the way the battery drains depends on previous battery usage data hence the reason why it last longer after a few days of use after a rom is flashed. It needs to build up new data to correctly report battery use. Maybe I'm wrong but my experience supports this.

I am running Alien v4 with the stock kernel and I am getting well over a day with pretty heavy usage (phone calls, texts, emails, FB, twitter, XDA, Games). My setup:
Battery Mode= Maximum Battery Savings
Auto Brightness off, usually on 30%
Unused blur apps frozen
Reinstalled performancemanager.apk (blur task manager), set to kill unnecessary apps after 2 minutes of inactivity
No overclock, I don't see the need to overclock outside of high benchmark scores. Without overclock I still play every game smoothly without any hickups or slow downs. The phone still feels super fast without it.
I turn off all unused services (gps, bluetooth, wifi)
After you charge your phone and take it off the charger, reboot it.
It seems that a process kills the phones battery after you take it off the charger. You have to reboot after taking it off. It works wonders. Currently on 16 hours of use @ 45% battery on alien rom with stock kernel.
Cheers.

I just noticed (read on the Alien thread) On the unlock screen, hold the home button and it unlocks. I wonder if something like in pocket detection keeps the IR eye on all the time.

So I have the rev11 nexus 4 and it seems to have pretty awful battery life.. I'm running cm10.1 with the latest faux kernel with the faux clock app all set up: min clock is 594, max set at 1.35, intellidemand governor, eco mode and snake charmer on, voltage at -50mV, as well. I can't fit hardly any apps on this phone because I mistakenly got the 8gb version and can barely fit all the pictures and videos and music.. So no rouge apps or anything effecting the battery (I've already checked). The phones battery is at 40c, and CPU temp at 56c. Because of this, even when I have my phone set up the way it is and the brightness all the way down, I still only get 3 hours MAX of on screen time before it shuts off, completely dead. I've had this phone for a month but I'm about to call for yet another replacement (first one was defective but still had really good battery life). Does anyone have similar issues and should I definitely call and try to get a replacement?

Battery drain is mostly caused by installed user apps running in the background and/or sync settings. Have you installed BetteBatteryStatts to see what consumes most energy? Also install CPU Spy for deep sleep issues.

Well as I said in my post there are no rogue background apps. The only apps I even have installed are reddit, fauxclock, cpu spy, and xda. I've looked and no internal processes use up much battery also. It's just the screen which is on the lowest brightness setting that seems to suck all the battery which usually doesn't even last three hours.

Maybe a faulty battery, i get 3,5 to 4 hours screen on time with 50% brightness. Running stock rom and kernel atm.
I haven't had any battery drainage with my N4, but with my previous phone I did. In most cases when I had that type of drain, I would reflash the radio or flash a different one and that would cure it. I'm not sure what would cause the drain, but I was flashing different roms and at some point radio performance would drop off. I have seen some complaints with severe battery drainage with the N4, but I haven't seen anyone trying a fresh radio install. Might not help, but could be worth a shot.

I think what I'm going to do is just flash it back completely to stock and just use it for a week without installing anything. If I still only get 3 hours of screen on time I will try to RMA it. There just has to be something screwed up with this phone though because my last phone with the same settings applied got at the very least 5 hours of screen on time. When I can't even go through half a day on this phone with normal usage, even after tweaking and cutting performance along with always having low brightness then I think there is a problem.
My Son's Nexus 10 had served its purpose. But Started to die at Random percent, Mostly above 50%.. So Got a new Tablet for him. But Did not want to throw away this Gem of a Tablet.
After weeks of Trial and Error finally found a solution Thanks to input from a Redditor.
Issue/Problem: Dies at Random % showing battery %0 and Shutdown. But In Recovery with Full Brightness it does not Die for hours.. (as later found out.. Recovery does not need much CPU power)
So What did I try:
1. Changed Rom's (All the way from Base Google Images to Oreo) >> Did NOT fix the Problem
2. Clearing battery stats.. etc. ( incl completely discharge and Charge and all those cycles usually we do to calibrate the battery) >> Did NOT Fix the Problem
2. Ordered a New Battery - (Samsung Model From Ebay - I guess it was used or who knows ) >> Did NOT fix the Problem
3. Changed Multiple chargers (Wall Adapters/ Cable from multiple brands which i have at home.. LG, Samsung etc etc) >> Did NOT Fix the Problem
Solution/ What Fixed:
Thanks to redditor.. Who mentioned about CPU power consumption.. And Old Mother board might not be providing enough Power to CPU. (As this tablet is Old.. It was just an Hobby to make it work and Did not want to spend more money on MotherBoard)
By this time I was on Marshmallow Linage OS Rom.. (As Everything works), Gave Root access to one of the CPU app's and Did this..(See Below) Enabled on Boot to keep the same settings.
Setting the CPU max to 1200MHz and Min to 200 it WORKED! I tried every damn thing before. For some reason... this idea did not strike my brain. So its the Power consumption from CPU.
EDIT 1: after some more testing You can go upto MAX 1600MHz (Your mileage may vary)
Finally Battery drained till zero without shutting down.
LET ME KNOW IF THIS FIXED YOUR TABLET TOO.. If you have the same issue as mine. (I Know many had this issue like mine.. but none had solution) Hope this helps.

Unfortunately at the moment I don't solved the problem, even if I set the cpu min to 200 and max to 1200.
I've installed a new ROM, deleted the cache and still the problem persists. I will do other tests trying to recalibrate the battery.

Also Before coming this conclusion: I did the fowling
Charge 100%
Delete Batterystats.bin
Run this command from adb "adb shell dumpsys batterystats --reset"
And then Changed the CPU max (Please NOTE , Select "On Boot" to keep the same parameters). Once u change the CPU settings .. Reboot and see .. if its keeping the same settings.
Many thanks. I tried all of the the things you tried and setting the cpu max frequency is the only thing that worked.
I could get away with seeing it to 1600.
Deleting batterystats.bin does nothing https://www.xda-developers.com/goog...-battery-stats-does-not-improve-battery-life/
Now with a new battery, PureNexus Rom and your amazing fix my Nexus 10 is a thing of beauty again.
LET ME KNOW IF THIS FIXED YOUR TABLET TOO..

Streetmart you absolute legend. I'd never thought I'd see the day my Nexus 10 would drain down to zero again. I tried 1600, then 1500, to no avail; then I said screw it I'll just go down to 1200 (with little hope of it working).
It feels so weird to actually have an internet “solution” work. I'm super happy. I didn't want to buy another tablet. I love this one and it worka perfect for what I use it for.
Thank you! :good::highfive:
OMG! thank you for this thread! i was just posting to look for a replacement for my 10... i hope this fixes it BTW.. what's the normal max cpu speed? I REALLY don't want to replace it as the new dropbox 3 device thing really screws me..

I think the normal is 1700MHz. It's what the program showed before I changed it. All the best! Keep us updated.

What a difference... i installed that a few days ago, and i haven't used my N10 much but on standby it's still at 99% usually it would be WAY lower.. i think that program did more than just lower the max cpu a little.. don't care though. the N10 lives on!!
If you still have this issue, I have been updating the kernel and also found some of the power control settings needed tweaked. Disabling "opportunistic sleep" "logging time spent in suspend" and enabling "advanced power controls" seems to do the trick. had an issue where the device would shut off if battery level reached 20%. Haven't had it happen again yet.

I'm currently running at 1600 with this guy modified kernel and wow, besides no more suddenly shutdowns it runs very smoothly, it reminds me the pre-marshmallow age of this tablet.

Where are you finding these control settings to change?
I have replace the battery of my N10 because of low capacity.
Now it charge from 0% to 52% then it goes to 100%. On discharge it goes from 100% to 46% then shutdown and battery shows 0%. Percentage is the same in TWRP.
Since replacement of battery it have aroud 10 charge/discharge cycles without any changes.
Any solution for that?

I have to agree on, that the N10 chipset/cpu/powersupply has degraded somewhat & as the battery voltage gets lower during discharge, it can not supply stable power any longer :crying:
If i reduce the CPU speed from 1700MHz to 1200MHz I get to go down to 20% instead the N10 shutting down abruptly at just 30%
I do have a spare battery in the fridge for later on. Once I open up the N10, I'll see if there is a capacitor or two, that could replaced in the power supply area to possibly fix the issue.
Note:
1. On second full charge since lowering the CPU to 1200MHz the battery got down to 14% & I have decided to charge it instead of letting it die at some point at a lower percentage
2. I should have mentioned earlier, that I still use the original N10 battery & plan to replace the original battery with a new aftermarket battery later on if I need to.
3. I use the N10 in an air-conditioned room for no longer, than half an hour at a time only browsing & reading articles with a short 10min video from YouTube.
4. Before lowering the CPU clock from 1700MHz to 1200MHz, the tablet consistently has shut down abruptly, at 27-30% battery level to my dismay.
5. Tried complete battery drain / cache reset to 0% in Recovery mode & then fully charging it while shut down 3 times without success.
6. So far lowering the CPU clock has made a difference & for prof now I am evaluating the N10 battery capacity with AccuBattery.
7. I charge my devices at around 20-25% or higher up to 80% to prolong battery life using apk's to stop charging or alert me.
I have switched to the UNOFFICIAL Resurrection Remix for Nexus 10 (ResurrectionRemix-M-v5.7.4-20161208-manta) MM ROM after rooting my N10 (Danke schön Corinna ) & had to update the baked in Kernel Adiutor.
Installing from APKMirror the "Kernel Adiutor (ROOT) 0.9.73 beta (Android 4.0.3+)" has allowed me to lower CPU MAX Frequency and have it stick after BOOT!

I don´t think so. The capacity of new battery looks really good. I use the N10 as wall-mounted control tablet for my home. With activated DT2W, full brightness, showing cams on motion, controlling home and audio over the day, my new battery runs about 28 hours before it stops. With old battery it was around 15-18 hours from full to off. My workaround: Reading battery with tasker and starts charging at 50%
I think the china batterys have different voltages than samsung batterys and N10 can´t work with this.

Hey,
That sounds very interesting. I may find out about that, when I replace the original N10 battery to my replacement battery from China.
I forgot to mention in my post earlier, that I am still using the original N10 battery. The original N10 battery keeps crashing at 30% unless I lower the CPU clock to 1200MHz.
After the first charge at (1200MHz max CPU) I got the N10 down to 20%+ before crashing to shut down & after the second charge I got it down to 14% at the same 1200MHz without crashing to shut down & just recharged it. Mind you I was just surfing the net & watching YouTube. I am also using AccuBattery to estimate the battery capacity atm. (Oh & don't install Battery Charge Limiter, because it boot-loops the N10 after install!)
DT2W sounds awesome. Which ROM are you using on your N10 to get DT2W, if you don't mind me asking?

Sometimes it shuts down at 20% and other times it won't. I'm almost pretty sure it doesn't have anything to do with advanced power settings or any kind of internal power settings with the kernel. There are no thermal configurations on this device and they don't add any drivers for it or support for it until much later versions. Heat seems to play a role especially down here Florida when outside. So far in my experience it's most likely to shut down at 20% if it's too hot and not likely to do so if it's been idle for a bit or not plugged in.
