[Q]Why I don't have any free RAM after 48 hours of uptime

Sorry of OT in other topics!
OK, why is that thread?
Because I and some other users have really big problem with free RAM after 24 hours or less after uptime.
What does it mean, problems with free RAM?
From the first day with my new SGS I9000 first on CM 7.2 and now on AOKP M5 I Notice a problem: very fast dropping of amount of free RAM during uptime. For example after reboot I usually have about 140 mb of free RAM (cached processes included). After 24 hours free RAM drops to about 70 mb. I installed 'Memory Usage' to figure a out What is going on... And I saw one strange thing: Just after reboot 'Android system/settings storage' process consumes only about 50 mb of RAM, after 24 hours - 84 mb, after 48 hours - 107 mb.
Few images follow... Please notice I always made a screenshot with same amount of services running, except first one, there 'NOVA launcher' is not a service, but a cached process. Lately I switched to 'APEX launcher' cause it has 'stay in memory' feature to decrease launcher's redraw.
Just after restart

After 24 hours uptime
After 48 hours uptime
Again I use AOKP m5 with xl bm Devil2 kernel (40x mbs free). As you can see after 48 hours I have ONLY 41 mb free. What that 41 mb mean, that mean I have bad multitasking, few cached processes; and after I start something big (recent angry birds or instargram) that big process will stop all cached processes and even several running processes (in my case it shuts down whatsapp, dropsync, apex launcher and so on).
Before SGS I9000 I had lg optimus one p500 with same amount of RAM available for user (around 420 mb) and I NEVER had such issues.
It could have 100500 hours uptime without any decreases of free RAM and with great multitasking. Same screenshots from that phone will be uploaded here in 48 hours to prove.
Now guys please be so kind and test that on your ROM (ICS, GB, stock, custom) and post here your results. I need just 3 figures: 1)amount of RAM 'android system' consumes after restart 2)amount of RAM 'android system' consumes after 24 hours uptime, and 3) amount of RAM 'android system' consumes after 48 hours uptime.
You don't need to restart-wait 24 h-wait 48 h. You can check your results now (any hours uptime), wait +24 hours check results, wait another +24 hours check results, than restart, check results and post them here. And if you have spare android phone in your family, PLEASE test it too and post results here. It can help us and me understand if I'm wrong or right noob with I9000, if it's Samsung's issue or CM/AOSP issue. And yeah, sorry for bad English. Thanks for participating.
Edit 3: I use very low minfree taskkiller parameters , around 24 mb, to keep as much cached processes as possible
Edit 4: If you don't have that problem, please, share your setup (ROM/kernel). Thanks. (changed title)
Edit 5: Don't say 'I don't have such a problem, you, stupid noob' if you restart you phone every day and don't have experience with uptime more than 24 hours!
Edit 6: Removed other ROMS
Edit 7: 'Android system/settings storage'

I have a solution for you..
1) reboot once a day
2) don't use antivirus apps
Problem solved

Why? Who cares? First stop using the word '****', second before you ask
people to let them report their memusage it definitely might be a better
plan to google, look and search how memory/cache works and how to keep
it in hands, before saying it or trying to say it's a problem with the OS/ROM.

Try it with swap on devils kernel. I got 1.5 gb ram memory No problem with low ram.

I don't want to reboot, it's too easy and doesn't solve the problem in the root.
not solved, it will only free 15 mb, and that 15 mb will became consumpted in a day a so

Thanks, was frustrated, corrected that word. Again, don't think it's global android's memory management problem. But of course I can 99% be wrong. But why on my old phone I didn't have that!?

It's probably you, your apps or something, i've never had such a problem.
Rephrase your question and ask nicely if someone could help you fix your problem because no one else will probably join you in posting ram stats because we dont have this problem.
Sorry if that seems disapointing, but it's probably not the OS or the phone, just your OS or your phone.
Perhaps ask in the AOKP thread, they might be able to help you seeing as you're running their rom.

I know it, 'free ram' in running services tab is all cached processes + real free ram. I said about the ram for cache processes.

Thank you very much!
Can't press Thanks for now, will do.

Tested latest CM9 nightly, working fine here for 50 hours. Plenty of free RAM for cached processes (good multitasking), 'android system/' process consumes only around 55-61 mb, no 'memory leak'. So it is (was) aokp's issue.
I'm really sorry for blaming CM9!

Depends on how many apps u have installed,try delete some of them..
have u ever tried a cache cleaner?. Try "easy cache cleaner" search play store. Android piles up loads of s... from the apps u are using and that is usually why your phone seems lagging after some days of use.
Anyway, u need to reboot your phone once a day or two. Just a good advise

I'm on AOKP milestone 5 with midnight kernel and i notice that system progressively takes up more ram as well, although it plateaus around 65mb ram. So it probably isn't AOKP issue. After 4 days without rebooting (with all ROMs i've been on), things seem to slow down a bit, and free memory seems to be lost somewhere.

I experienced it on aokp, as I said. Now, on latest CM9 - I don't have any problem with growing 'android system/' process and I have enough of free RAM.

I know about it, and it doesn't depend on amount of apps installed, but on amount of running apps with services. Cache cleaners useful for cleaning some free space on internal (phones's) memory (/data partition I believe).
And I don't want and need to reboot my phone every other day, because I don't have problems with free RAM with latest CM9. But still, Thanks for advise.

Good battery life for 2 days after ROM install then getting worse.

Hi, I know a lot of people are having this issue with battery draining, but mine it's kind of illogical, After I install a new ROM the battery life is good, even very good, then after the 3rd or 4th charging the battery life gets worse and worse with no apparent reason. I'm struggling with this problem for over a year now and I can't seem to find a solution. It was all ok, till I got back from France last summer and I observed my battery was draining verry fast, I was on ICS then, after changing almost every ROM I could find I bought a new battery, an original samsung 1650 mA battery, but the problem persisted so I tried all the ROM's in hope I would find the right one for my phone (also changed a lot of modems, the captivate ones seemed to have a slightly better battery life, but I couldn't hear the voice of anyone calling me). So what do you think might be the problem, software or hardware.
Now I'm on SuperNexus 2.0 - I9000 - Milestone 1 [02-06-13] and I think this is the best rom for battery life I found till now.

After 4th recharge and using juice defender:
In standby while I was sleeping (I thought everything was ok)
Than after going out with my friends: (The standby time was at least 12 hours.)
My location is disabled, no sync, I rarely check my mails, I'm mostly using Whatsapp, Google Play Music, Making a few calls and a little Facebook and iGag.
So any advice is welcome/d.

If its those apps that wipe that certain file (batterystats or something like that) then it won't work. The battery "calibrators" wipe a file in the system that actually has absolutely nothing to do with battery life.
Proper battery calibration is done through charge/discharge cycles. So at this point your phone should be calibrated.
By the looks of your screenshots it does appear that you use wifi and data quite frequently (correct me if I'm wrong).
Few things you can try:
1.) Change kernel. Many battery drain problems are related to the kernel. If you're on Supernexus, try Mackay or Latrop kernel.
2.) Change rom. Some roms are optimised for longer battery life (Gamerzrom, EXTRAordinary and Sexynogenmod are examples)
3.) Greenify. Very good app that allows you to "freeze" apps running in the background such as Facebook. It doesn't disable them completely, but prevents them from running in the background.
4.) Turn off auto-sync. This is under Data Usage. It does mean that you might lose some notifications and you won't have data synced unless you do it manually, but I've found it helps to save that extra bit of juice. Not such an important one as the others though.

I've always used Semaphore as a kernel (ondemand governor setting) and I at least experience 1 to 1.5 days of battery life (assuming normal usage)

Yes, you are right, I use wifi and data everyday, mostly data. I'll try to change the kernel to latrop, never tried it 'till now. As for the auto-sync I think i never had it enabled. The only app tha syncs is facebook. thank you for your tips.

[Q] General Battery Life Questions - Looking for Other Input

Have new Sprint HTC One and when first using it out of the box, battery life seemed to be real good.
Mods I have made.. Unlocked and am running OMJ's custom ROM.
Here is what I am questioning now.. (my 14 days are almost up):
I leave it charge all night and first thing in the morning, I use it for 15-20 minutes catching up on mail, facebook and news. I am connected to wifi in the home. What I am experiencing is a 6% battery drain from this pretty consistently and display on auto brightness in a dark room in the morning. Last night I set power saver to including cpu, diaplay and data connection. I had the display set dimmer than normal/what the auto brightness would be. I experienced the same 6% drop this morning.
I am not sure what to think, its kind of disconcerting to think you wack 6% of battery before the first cup of coffee.
I have no data, but am wondering if anyone has see lesser batter just from unlocking?
OMJ's ROM is pretty stock, so I would not think that is causing any issues.
I am looking to see what others are experiencing from there initial 15-20 minute usage.
I am open to any input that could help me conclude that there is not an issue with the phone so I can stop worrying about meeting the 14 day return deadline.
Edit: Adding images and info to attempt to create a baseline for others to compare to. Images are from GSam Battery Monitor available in the market.
The images show 30 minutes of use after unplugging from a full charge, Power Saver off, Brightness set to Dim and using WiFi. Screen using 18% and Apps using 75%... you can also see the specific apps being used.
It would be great if others could mimic and provide their results. This would allow us all to have something to compare to.

it could just be the battery technology. i know with some laptops here at work they dont really "fully charge" the battery to increase the battery life span. so this could be a normal thing. For me personally im more concerned about the phone lasting atleast through the whole day before i have to charge it.

Yea I mean I'm not sure how much you use your phone a day but I'm seeing consistently approx 4-4.5 hrs of screen on time a day. Unplug the phone at 7am and plug it in when I got to bed usually around 11pm. Some days if I'm watching a lot of video or playing games I'll have to plug it in around 8pm or so but that isn't too often

Anyone want to do a small comparison test?
Set brightness to auto, charge to 100% and then use for 15 minutes checking mail, Facebook, web surfing, or whatever (simple activity, not gaming), in normal ambient room lighting, using WiFi, Power Saver off. Then report your battery level after the 15 min.

I would lose around 10% from that. I think.

You should calibrate your battery any time you flash a new Rom, so why not try the app I suggested?

Oh, I am all over that. Did the calibration yesterday. I have not noticed a significant difference, but I do agree this is a needed step. Especially when changing between significantly different ROMs. Thanks for pointing it out.
What I am really looking for from others are some comparison results. I have created some pictures this morning and will be adding them to my post, in an attempt to create a baseline that others can use to do the exact same and provide a result. This should allow others and myself to see if there is any significant difference between our devices.

I edited my post with baseline settings and images.
Would be great if others could mimic and post results.

Hehe Sorry when I read my post it seems kind of snappy and nothing about your reply led me to this conclusion. I understand your looking for a comparison and I think its safe to say I easily use 5-10% of my battery life first thing when I get up and check all of my stuff.

Let's try one more time.
Sent from my lair.

Does anybody know if limiting background processes to zero will help battery life? My phone had 1hr 20min awake times with 12 mins screentime/usage after 8-9 hours.
This was with absolutely no power saving at all, whatsoever. Phone was around 75% after those 9 hrs I believe, with kernel taking 33%, and radio taking ~15. Fresh after factory reset. Only apps were Email, Doodlejump, GSAM, ES, Keep and Swiftkey.
Tomorrow I will turn off auto sync, limit background processes, and turn on power saver/sleep mode. Let's see how much that helps.

Here's what in doing most of the drain comes from having only 1 bar in my new dorm

Help re battery drainage and synapse optimisation

So I'm fairly new to the Android's scene, I've come from a jailbroken iPhone straight to the nexus 6 after doing a load of research on which phone I should get.
The iPhone is so much easier to work with, in it's jailbroken and default state. I've had my nexus for about 3 months now and only now feel alright using the words ROMs, kernals and flashing.
I want to optimise my nexus for maximum battery life, I know I'll have to comprise with animations and processing power etc.
Here are a few sc of how my set up is currently

I flashed my current ROM and kernal last night and did not charge over night so I could just see how much drainage there is when its on standby. This morning I charged it up to about 81% and used the phone normally and I've noticed my battery is actually depleting really quickly. Especially when you take into account I had my setting to power saver, and I was using pixel off battery saver and a kernal made for huge battery life.
I know the issue is with wakelock? But I can't find any help and what I can find is far too complicated to follow.
Also, synapse. That thing is a nightmare for a noob like me. If anyone could link me to a thread or website that explains each feature or somewhere where someone has shared their setting for getting the most battery life, I will be very grateful.
Thank you in advance

I'm sure someone with more expert advice than I can provide you on this topic, will help you shortly. :good:
I will suggest this though, look into a third party battery stats/wakelock detector app to more specifically isolate any wakelocks or battery drain. Also, greenify is an excellent option for root access.

well, your play store and android os is way to high on battery percent used! screen should be the #1 battery drainer(or close). other things shouldnt be that far above the percent for screen use.

I'm sure someone with more expert advice than I can provide you on this topic, will help you shortly. :good:
I will suggest this though, look into a third party battery stats/wakelock detector app to more specifically isolate any wakelocks or battery drain. Also, greenify is an excellent option for root access.

well, your play store and android os is way to high on battery percent used! screen should be the #1 battery drainer(or close). other things shouldnt be that far above the percent for screen use.

Yes, the fact that my screen wasn't the no.1 drainer is why I was concerned enough to start thus thread. Any recommendations as to which app(s) I should use?

android os i wont be too concerned about, since that changes depending on how you use the phone, but the play store.. were you restpring a bunch of apps or something? anyways, recharge your phone fully, then use it like you normally would, then past the battery results here, after a full use of the battery, and ill look at it again. next time past not only the main battery page, but if you press on the chart itll give you more info, paste that as well so we can see your signal, wifi, and if the phone is sleeping.

As for battery monitor, it will be more based on your personal preference but I have used this:

I downloaded a load of apps because I did a clean flash of benzo. I'm currently charging my phone and will return with more screen captures as requested

if you downloaded a bunch of apps, thay would explain why. anyways, the first 2 battery cycles after flashing a rom will be a little lower than normal. after, battery should be better.

again, you just flashed franco kernel, so youll have to give it a battery cycle or two to regulate, then you can start judging battery life. but your device is goung into deep sleep, so that's good. also, do you always keep wifi on? if you keep it on, but dont use it it'll drain battery. also, what do you have your brightness set to?

OK, thank you. The issue is me changing kernals and ROMs etc. I'll cycle my battery 2 time as you've said before I start to judge battery life ty.
Yes I keep WiFi on and use wifi. My brightness is dragged right down with adaptive off, I then change it to 50-70 if I'm outside.
Thank you very much for your help though

Synapse is confusing to anyone who doesn't know what they are messing with...try FauxClock or Trickster Mod...much simpler and you won't have to worry about changing things by accident by swiping to the next page as you would with Synapse.

Simms is absolutely correct - after a rom or kernel flash you need to give the phone a few days to build up its cache etc...only after that can you properly judge battery life and performance.

screen brightness is a MAJOR influence in battery life. i generally keep my brightness down below 15%. if i raise my brightness to 30-40%, then ill see 1 hour less screen on time. normally, ill see anywhere from 5-6.5h sot. another major influence is the quality of your phone/data signal. some people, no matter what they do, will never have good/great battery life, just because their signal quality is lousy.

Somewhat off topic, but Better Battery Stats is a great app for getting a much more in depth idea of battery life. It'll also give you all the wakelocks, which can be handy if you looking to do more in depth troubleshooting.

Huawei P9 battery issues??

Hello!
I love my P9, but there is one problem. I get very bad screen on time, and I don't know if my battery is bad or something is wrong with my phone. Can someone please help me resolve this issue?
Thank you!

I got the same problem. Sometimes it heats even when not in use

Same problem here. The problem is that it drains a lot in standby with 4g. In wifi it the drain is ok.

Yesterday i did a "reset all setting" not factory reset and it seems that the battery is much more ok. My phone does not heat up like it used to do. Maybe a setting that is causing drain in the phone. Will continue to monitor the phone and will give more feedback
Hope it helps

I was able to keep 12hr.. which is quite a big difference for me since I bought the phone [emoji23] i did not use the phone quite heavily today only like 1hr30 SOT.
One thing i cant understand is the high power intensive app that i dont protect keep re opening after cleaning them. How to stop that? I think that this is causing a bit of battery drain. Will not chargw the phone till tomorrow to see if it will stay on. Will post more screnshots tomorrow

My battery discharges 5% after 6 hours of sleep. Is this normal (I've got no protected apps)?

When i bought the phone on 23.05 i was able to achieve constantly 8 to 9h SOT with one charge. Software version B136. Last month this is mission impossible, max 5 to 6h SOT. Same usage, same apps, same settings... Now i am on B182. I wonder if the battery degraded already?

Is Android system consumption level normal?

My Android System battery consumption is always low. Today's usage from 100% to 84% battery level:
Downgraded to B136 and will see after couple of days...

Found previous thread, gonna try formatting SD card with phone, maybe it'll help.

I got alot better battery from deleting facebook on the phone. Still have messenger though. I removed all of facebooks permissions, and it would still open. Both facebook and android uses 100+mAh. If I left the phone over night it would use about 40% of the battery from being idle. First day without facebook and it used 4%.

Using some of application , i get a result by measure the battery capacity is 2900mah , not likely as huawei manufacturer said it is 3000mah .
Anyone know this ?

No , you are wrong
The way you use it affect on the battery. If you just open light app as web browser, video, you easy get 8-9 hours onscreen time, but you play game , or use too much 4g to suffering, it will hurt your battery hehehe

OMG! You have changed my life!!!
No! You are wrong! Because i know how i use my device! When i say "same usage, same apps, same settings" that means exactly what you read! To the last letter! I don't use social apps, i don't playing games. Battery life is worse only six months later even on B136. That leads me to conclusion for battery degradation. Is this clear enough?
Thank you.

Did you use the software update via OTA or flashed another firmware manually via computer?
Honestly I'd stick to OTA to avoid battery drain issues caused by software.

I always use dload method to flash new firmware or roll back to old one then factory data reset twice. No drain, no unwanted background processes. Just SOT is not the same as was in the first couple of months. In general is not big problem for me just sharing my observation. I will order a new battery and will replace it as soon as possible.
