I have poor battery life on my desire, it barely lasts 7 hours. I have tried wiping battery stats etc, and have the screen brightness at 50%. I have read that some kernels can greatly improve battery life, is this true? If so, which would you recommend, and do I just flash it like I would a rom? I am using the latest miui.
Cheers,
Steve

They can but finding the underlying app causing the phone not to sleep would be what I'd be looking at. Remove all installed apps and add them 1 at a time and see how the battery goes

Yeah i've tried this, there's nothing draining the battery.
Not at all
Such battery drainage can only be induced by either heavy usage, or phone not being able to go to sleep.
The differences between kernels in custom roms are merely a shades since all of them are pretty much battery efficient. You won't miraculously jump from battery life of 7 hours to 30 hours. Concentrate on your apps or even better, third party Widgets.

Probably a hardware fault then - the OS on it's own with no apps installed shouldn't drain a battery that quickly. Did you also turn off the sync options to test that theory?
Personally sounds like a knackered battery/phone
If it isn't apps/widgets (they are the culprit for heavy usage) then it would prob be a faulty battery. I did a little test last month to see how much battery I could lose in 24 hours. I lost 8%. I guess it could be a baseline to start off with.
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?
Hello,
My battery life hasn't been so great as of lately. IDK if it's ICS or if because my battery is nearing the end of it's life but sometimes my phone reboots and I lose like 30% battery out of nowhere. Is there an app that anyone can recommend to test to see if a battery is still good?

Its kinda an issue with our phones from what i can gather. It seems at 50% or lower it will drop in large numbers when it reboots. I read if u have to reboot to turn on airplane mode before reboot. They say its a fix but i can not confirm.
UnOfficial
Not sure if it's an app to test if your battery is still good but you can test if your battery is bad by taking it out and see if it's bulging on the sides.. Also if you let you phone die alot or alot of deep charges that will kill your battery (its best to charge our batteries as much as possible for long term health)
In the meantime you can grab GSam battery monitor from the market or better battery stats to see if it's something chewing up your battery

Are you stock ics or are you on a custom Rom ?
If your stock ff18 ics, this is as good as it gets. If on custom Rom you may have options to tweak settings and save some batt, custom Rom wise the better ones are near stock, the more bells and whistles custom roms have the greater battery hogs they are.

A few months ago I had paranoid rom that was great on batt life. 3% loss from midnight till 6am.
I was blown away that I could use this phone so much and it hardly ever drain batt.
Kept telling me there was an update so I did and battery life went to hell...
Tried some others, Aokp and now liquid smooth. LOVE the Liquid smooth, but 25% over night is un-acceptable. this thing on the last few roms is constantly needing charged.
I tried restoring that one version of paranoid, but just wasnt the same.
so curious on suggestions on a better ROM or something.
There is no answer to this question. Different people have different preferences and experiences. If there was a ROM that was clearly better than the others, almost everyone would likely be running it.
Your best bet is to find out why your battery is draining. Use something like Better Battery Stats to figure out what apps may be draining your battery. Perhaps it is an app or two that is synchronizing a lot. Perhaps there are wakelocks.
Alternatively, it could also be hardware. Perhaps the battery is dying. Perhaps the USB port is having issues, and it wakes the device/screen up from time to time.
thanks cup... i just wiped and put that old one back on... will check it tonight. then ill put that better batts stats on.

Hi all.
I am a new user of this community.
I am looking for a fix to my troubles.
Two weeks ago I updated my s4 mini to KitKat via OTA.
My Galaxy was TOTALLY officially, no custom rom, no recovery, no root... so i updated in the "classic" way.
From that day my smartphone drains battery really, really, fast and becomes really hot.
I am talking about 50° celsius when i only browse internet or use whatsapp to send message, and in the same time the battery drains fastly.
I rooted the phone, look to wakelock, look to process that could drain it, i made two factory reset, flash via Odin to the Italy Stock 4.4.2 (before it has got the English firmware version), buy a new battery, use different charger, calibrate it by app, calibrate it with the non-root method... but the problem persist.
I have got GPS off, Wifi OFF, NFC Off, S-Beam Off, Bluethoot Off... i only use internet via GSM or UMTS, no LTE.
To browse I use Opera Mini, but it's the same thing with Chrome.
I don't know what to do, i don't think it's an app problem, and it's impossibile that is by hardware, because with Jeally Bean the smartphone goes great.
I am actually trying Coolify after try Battery Doctor and a lot of other apps, like Gsam Battery, Greenify, Battery Calibrate ecc...
I've attacched some screenshot here. How can you see by the battery graph the battery drains like there's not a tomorrow in same time :crying:
ps: sorry for my english, how can you see by the screenshot i am italian.
Mee too I have this problem

You have to root and install recocery on your device. There's a thread arnd here created by Arco for you to find the recovery files. He also provided a kernel for KitKat regarding the wakelocks if im not mistaken. So flash that kernel and like i said, recovery and root is needed.

You may have a faulty firmware installed. Try updating to the latest one with Odin from sammobile.com.

tnx for your information...which that be soon suported 4.4
Android says me that i've got the 56% of battery at this moment, with about 5 hours to use (only 34 minutes of screen on and GSM only mode)
In the same time 3C Toolbox says that i've spent the 34%. That's mean i've got the 64% of battery.
It could be an Android indicator error?
I tried to calibrate battery using Battery Calibrate, now i will do it with 3C toolbox, maybe it's better.
So, using Coolify i see a little improvement in temperature (never up 45°) and the drains seems go slowly then before.

If its the indicator, then what causes the CPU heating? Battery indicators in all devices are not accurate even after making it "accurate". Like eg, my Galaxy Wonder had 18% battery. After reboot while charging i got 90% and lasted a few hours. But honestly, no heating issues back then.
I still am confident that its a kernel problem. Being a flash-a-holic, i didn't try the 4.4 update then cos of KNOX

Yes, probably the only things to do is flash a new kernel and a new rom.
But i bought only 6 months ago this f***ed Samsung, so I don't wanna loose the warranty (i love my old Galaxy Next, i could flash it how many times i wanted, because there isn't no stupid knox)
I installed the App Opp Xposed Framework, i found that Google Service uses location even if i say him to don't use it, and even if i turn off gps. So I stop him, I even stop the "keep awake" options in his menù.
But in 5-10 minutes i didn't watch any differences in battery life.
So, i risked to put off "keep awake" in "Android System" (because i watched that "android system" keep awake the phone often), and nothing it's happening now. I am charging my phone, then I will try if there's battery improvement (but i don't think)
Same issue here. Got the phone two weeks ago. Sometimes during charging it would heat up to 47C. Also is this normal battery life?
Note: Power saving is on.
Mine got to 49C yesterday at 2am before going to sleep. Literally, when I touch the screen, I feel it burning. I'm on stock ROM. The battery, on the other hand wasn't one of the worst times I had it. It went down drastically from 10%, which isn't bad compared to going down drastically from like 30% like I once had.
It may be a battery problem, and it may be a firmware problem. But I suspect that it's both. I got 2 batteries, and when I have problems with one, I turn to the other, and it's a continuous loop. I guess 4.4.4 will fix some of the problems, hopefully.
The screenshots explain everything.
Peak temperature at 49C. The constant green line (straight line) shows when the phone was off. You can see the temperature going down then.

Its a Samsung problem. People actually told me to steer clear off 4.4 update to get away from problems like this.

Searching online I found that battery drain is a problem of KitKat 4.4.2, and that S4, S4 mini and Note 3 are the most affected by this problem. The factory reset, that is often suggested is useless. I made it 4 times in the last 2 weeks.
I even change the stock rom, from the UK 4.4.2 to Italy 4.4.2, with no improvement.
The only way is to wait an official update (if Sasmung will update again this phone), or try a Lollipop or 4.4.4 custom rom.
I could say that rooting the phone by Towel Root (knox 0x0 flashing before the old kernel) and using:
- Coolify (with this app running in background in 3 days the phone stay under the 45° celsius)
- App Opp Xposed (deny the access to position to any app and put "Kepp Away" off for a lot of app)
- GserviceFix
- DisableService (to stop some process, like the wereable process on Google Play Service)
And freezing all the useless software pre-installed, i get some little, but important, improvement
At this time I have 50% of battery with around 3 hours from the unplugged and with around an hour to use with display on in gsm mode (no wifi). Before KitKat updated this wasn't good, but if i hadn't root now i would have 35 or less percent

I would be better off with a custom ROM than Offcial Samsung Stock ROM. 4hrs of SOT (without WiFi) just with light browsing, gaming and some video watching
I do understand you guys don't wanna void warranty but I guess its better than buying batteries every month
Anyways, i guess some improvement for this is simply to wait for Samsung's update OR try out greenify. I believe Greenify can hibernate apps that causes the most overheating

For what it's worth I had similar over heating on my i9300 and my current phone i9195. I believe it mostly stems from the screen. The screen in a phone and laptop will be the biggest drain on power, by far, second to none.
Unfortunately, once a battery has experienced regular rapid battery loss from the screen being on too bright and too often, the battery becomes pretty poor at holding charge. And one of those screenshots shows the screen zapping the most... Remember, even if its on charge it's still hitting your battery for power. Now I never let the screen above 45-50% brightness.
If you're running stock and have power saver activated then turn the screen down, and remove as many unnecessary apps as possible. If you're rooted then there's plenty more you can do and my favourites are Droidwall to prevent apps from using your mobile connection and a custom kernel with app to under volt the cpu and gpu, but there's a lot more you might be able to do...

I put the S5 Proyect rom with Brisk Kernel and the problem persist.
It's not possibile was an hardware problem, because in Jeally Bean was everything fine.
But now it's really strange, sometimes the battery drain a lot, but yesterday night with the 10% i use it a lot to whatsapp before to see it shut down automatically. I don't kwow what to do
A battery isn't considered hardware by most as its a consumable; its not expected to last the lifetime of the phone.
Just because it was fine on JB you can't discount the battery cells failing. I assume you went from JB to KK, and not downgrade? If so i believe the screen zapping the battery too much causing the battery to begin failing holds true...ie, 6 months ago it was fine on JB but now its bad. Between then and now the battery has been hammered.
