Search for the best battery saving OS

Hi ,
currently I'm running CodenameAndroid 3.3.0 on my Nexus S and everything runs smooth and works perfectly well for me, no doubts. But somehow I constantly get the feeling that the newer our operating system gets our batteries drain faster. Either this or my battery just gets old. However I'm searching for a Rom that has battery saving in main purpose. I dont care about playing games, the operating system or showing off how great my phone is. For this I have my Tablet The best solution for me would be a rom which is very low in batterydrain but as smooth as jellybean (maybe just port the transitions over). I know it might be hard to find something like this but is there any rom which matches my perception? Also a nice look would be cool, too ^^
I'm waiting for your responses!

I think you're looking for SlimBean. I'm on CNA too, the batter life is pretty bad

I tried SlimBean because I used SlimICS before but I miss too many features to change it back. Isn't there something else? Or which OS has the best batterylife in general?

i think gingerbread still has the best battery life.

androxide got me over 4hrs of screen time and a days usage with matrix
the new miui jb is also almost the same

IMO.....ICS's best battery life is on Kangy Ultra Ex 1.3 by DaXmax.
Just as long as u don't use Google talk since that's the ROMs only hiccup.
Then again like most will say.... its all depending on the user so hopefully it will help if u try.
I'm currently using the same developers JB ROM called paranoid Android..... so far it great but again I don't use all the newest features to much yet. I'm working myself slowing into the stuff.
Good luck
Vs Nexus S4G using tapatalk2

There is no ROM with super battery life, some better and some worst, very similar.
Most u can get from nexus s is +4hrs screen on.
And i don't care about those pathetic screen shots with +7hrs of screen on.
Fire up 3g/H stock browser, maps, music etc and we'll find out how good ur battery life is.

MIUI get's me aprox 4 hours and 50 minutes of on screen time. Lots of game playing, instant messaging, syncing, music, and social media (Instagram, twitter, tumblr.) And about 9 hours + when it get's to about 14%
EDIT: This is when using WIFI, not my 3G.

This question will produce every combo under the sun...but in the end no Real answer. Every phone/battery is different and how the person uses their phone. Apps installed, how much you use said apps, are the ram hogs, 2g, 3g, I could go on forever...just like this thread will if not eventually ignored or closed.

Closed, there is no answer to this question, the majority of battery drain will be the screen (depending on brightness) and whatever app you have installed and use.
Generally it's a matter of finding out what works for you.

[Q] N5 Performance 6 months on

Xda!
I have noticed in the last month my N5 starting to become laggy. To be fair I do push it to the limit. I have over 180 apps installed, it's rooted but on a stock ROM with some Xposed mods.
I'm quite aware that a factory reset would sort my issues out but I simply do not have the patience to input all my user data again to get back to where I am today.
Do the good people of XDA have suggestions on diagnosis for my lag, which has become noticeable. Is there a way for me to find out what processes or potential issues I may have which are begining to really hurt my performance and user experience.
Day one this was the zippiest device I'd ever been fortunate enough to lay my hands on. I want that back!

Do you ever wipe the cache/Dalvik? If not, I would start there.

Although I think there is a certain element of getting used to the speed of the device over time (so a perceived slow down takes place), the installation of apps that run on boot can also cause issues.
I think the best bet is Greenify anything that you don't need running in the background. For example, the BBC Weather app seems to want to stay in memory 24/7 when I maybe use it once a day. If there are 10 such apps using RAM, that will impact performance more than anything. The number of installed apps should actually have quite a small impact on performance if they are "dormant".

Thank you for the two suggestions.
Clearing the Dalvik and cache took an age but seems to have made an immediate impact once the system settled in on boot. I haven't updated my greenify list in ages so that is something I will box shortly....

[Q] Ram management issue on the s6 causes lag?

Hey guys I am sorry if this question is asked again, but does the ram management issue on the s6 cause lag in day to day usage or it just deters the multitasking performance? Gonna buy the s6 tomorrow, and Im damn excited

It will mean if you use the back key to come out of apps, sometimes they will reload, such as phone and messaging etc, but only usually games will be closed regularly and aggressively. General lag isn't a problem, just a slight delay loading aps back into memory once they've closed.
I find if I back out of apps using the home key this problem is reduced.

How about scrolling through apps such as chrome ,Facebook ,play store. Does this issue cause any lag?

I've never really experience any huge lag. I turn off my device once in 2 days so maybe that helps.

90% of users won't even notice the memory management "issue". Only hardcore multitaskers will. The "issue" is the S6 kicks apps out of cache very quickly so whenever you tap the multitask button, the app relaunches/redraws instead of resuming from a hibernated state. There is a little lag (~0.5 second), but it is not a dealbreaker that would prevent you from enjoying the phone.

Chrome lags on every device I have owned, including the S6. Any app that uses Android WebView will lag.
I don't use facebook, so I can't speak for that app.
No Play store lag on my S6.

Really, I did'nt notice the problem with multitasking (because the S6 is so fast) before I read about it here.
Also, all the **** you hear about the battery life is not true. Of course, it's not the best out there (only 2550mah, so of course not) but it easily get you through the day (normal usage) and at least into another. The battery have gotten way better with a few updates (it was damn bad at the start) and might get even better when 5.1 hits in a few weeks.
Just turn of basic stuff, that noone uses anyway (almost) like, location history, wifi always scanning and such.

Glad to hear that, by the way 5.1 just came out recently and its showing mixed reactions among the users. Some people says that the battery life has improved a lot after the update and some just says its the same.

No, it's not out yet. At least not for the international version. Some users think, that the reason only one carrier got it yet, is because it is a "test" version. Not sure tho.
But well, as said, only out for one carrier for over a week now.

Yeah the battery life is overblown. It is no worse than any other phone with <2500 mAh battery. Anyone coming from a 3000+ mAh battery will be disappointed, but anyone that is used to plugging in every day won't know any different.
If you are rooted, I also recommend App Ops to manage permissions and save more battery :good:

Check Force gpu rendering and no lag. As far as it regards multitasking it sucks.

Multitasking/RAM

You're busy and don't have time to wait, which is why you need to stop reading this thread and get back to organizing your Pogs. Rate this thread to express how the Nokia 6.1 Plus performs when multitasking. A higher rating indicates that the Nokia 6.1 Plus keeps many apps in memory so that they don't need to reload, and that when moving between apps, transitions are smooth and performance is excellent.
Then, drop a comment if you have anything to add!

RAM management is Okayish

Ram management is not good. Heavy apps like pubg cannot run smootly and get reloaded when you use another app

The answer is gonna be different depending on whether you have the 4GB or 6GB version. My 6GB version is working very smooth, but I do think that the stock Pie rom closes apps a bit too aggressively. I assume this helps to save battery. My bootloader is unlocked, so eventually I plan to try out some custom roms too, and hopefully the RAM management will be a little less aggressive.

My device 6 months older now, stock ROM, now i can experience sluggishness in operation, i use stock launcher.
Sometimes it takes few sec pause to shuffle app, sharing between different apps, there are some glitches in performance now. Mine is 4gb/64gb variant.

I'm facing the same problem. While switching between apps, it freezes for a second. Don't know why this problem is. On the Mi A2, nothing like this happens. Very poor OS Management.

I don't think so. I'm using this from last one week and everything seems to be working fine. I have a lot of apps installed but they don't freeze nor does the system kills them automatically. I have enabled automatic battery management. I think you guys have little storage left in your internal memory. Try resetting your devices and it should start working fine. In case if it doesn't then it may be the wear and tear part for which I need to be prepared. Thanks.

Any custom roms improve pubg performance the device is Nokia 6.1plus 4gb reply me

ram management issue

So i have 8/256 zenfone on last android 10 update but multitasking on this phone behave strange random apps are getting killed in the background even if I use idk 50 % of ram and by night most of the apps are gone from memory.
https://zentalk.asus.com/en/discussion/comment/37973#Comment_37973 now some assus boy is trying to say that this is fine but no it is not -.- iam wondering if iam missing some option to turn off or any of you have some similar issues? Maybe iam missing some power saving option to turn off but i think i turn off all of them by now? :crying::cyclops:

Yes, by default this phone has fairly aggressive memory management. Most of the settings you'll want to adjust are under Settings - Battery - Powermaster - Battery Saving Options. You might also want to have a look under Settings - Advanced - Optiflex.

Think I check them all already but today have the same situation still. I even do the format yesterday and for half of the day, phone keep 24 apps in memory without reloading and overnight on charger phone just clean its memory and leave me to 3 apps open so it cleans 21 apps -.- 'm on the edge of returning it i pay 25 % more for 8 GB and my phone is pretending to be 1 GB device sometimes...

Even my older phones from Xiaomi and Xiaomi is widely known for aggressive ram management never went full retard on cleaning almost all my apps. :silly:
And why on earth it decides to save battery when its plugged to charger xD.

@berni502 is right. There's a bug with LMK or something. You can use RAM memory filler to test how much ram can be allocated to an app (and it gets killed at 5GB instead of 7GB on Pie). Since then everything gets killed even though there's about 4.5GB free, SystemUI included. Reboot fixes the problem. I think I'll open a new discussion there.

Pls do it! I feel like I am only one in there who cares : ( it seems that killing apps overnight and a way too aggressive ram management starts on android from android 9 there is a lot of ppl writing about it on pixel,oneplus and samsung forums but on asus is it just me : /.
I even find this site but think op resolve problem already because i have op 7t for +/- 3 days and it just works fine no even single app missing form ram overnight.
https://dontkillmyapp.com
I actually can semi confirm your observation about ram after reboots. Yesterday on clean install android 9 multitasking gets huge temporary improvement ram can get as low as 1,5 gb ram or even less but after a day 1 + unwanted ram clear overnight and my restart after this phone struggle to pass 2,8GB free memory it can handle way fewer apps in memory and start reloads them sooner.
First day on android 9 downgrade
VS
Second day
It can be fixed oneplus show it but they won't fix it if I am the only one who is barking about it on their forum.
BTW does your app getting wipe out from memory overnight? I mean from 20 + app get something between 3-9 in the morning and if not can you describe what exactly do you turn on or off in your system or you just don't touch anything?

Well, I'm not that hard multitasker. Of course I have some background services enabled but it's far from having 20 apps running at the same time. Regardless, after a week or so without reboot some issues become more apparent and LMK seems to be very aggressive even though there are 3 GB left (not even buffered).

I must confirm that you are not alone. I did it exactly as you described in one of your posts. Before going to bed I opened 24 applications, then I went through them all once again that they are really all loaded in memory (I have 6 GB of memory). When I woke up in the morning and pressed the multitask button, I was surprised to find that out of the 24 applications, there were exactly 3 left, as you have repeatedly claimed.
I stared at it open-mouthed. In fact, I've never done this check because the phone is fast enough that I just didn't recognize in the morning ((still sleepy) that applications were loading from Flash Memory instead of RAM.
This check is really simple, anyone can do it, but apparently not many users have done it yet.
Next time I would like to try to find out which applications actually stayed, whether the last used ones or completely random ones, and what processes took place at night that might be blame.

I am really tired now of talking to the Asus boys on their forum its is like talking to the wall. Now i get info from them that this is a normal android 10 case but don't believe in this... I use logcat app for 2 nights but I am not that smart to figure out what and where its happening am trying but I think it will be better to return this phone while i still can... : / in the end like i said i pay almost 100$ more for 8gb to have those extra multitasking abilities but they are ripped off form the phone.
From my observation apps stayed in ram can be different. It sad because that ram issue was reported in July on their forum now i don't have any hope in asus work on fixing this problem.
use ram truth or some app to monitor ram and you see some another strange thing even that after night you stay with 3 apps open your ram will be almost full. For me, it was today about 700 mb difference after overnight app kill.

Have you guys tried the same exercise of opening 24 apps and checked them back at morning with other phones?. I'm no expert, but it is my understanding that apart from the LMK that kills apps if memory is needed there is also a time killer i.e. if an app is not used after X amount of time it is killed from memory, so what you see is normal Android behavior.

I haven't had a reason to deal with this issue yet, but after a while searching, I'm starting to feel that this is a feature of Android 9 and 10 that users of various brands complain about:

Even if android 10 works like that so what? xD they modified many apps in zenfone system and change many options and not implement many aswell so what's wrong with fixing something that clearly works bad and it is no fitted at all for devices with 6,8 gb of ram and more(not even 4 i will still be mad it this happened to me on 4 gb xD)... hmmm, now I'm curious how it works on rog phone 2 this beast have like what 12 gb of ram ?

On the contrary, it is important that the links are older, because it only proves that this problem has been around for a long time (at least from A9) and in addition to different brands. The first link is from October 2019, which I would consider as current enough.

yes but they are speaking about anbdroid 9 and they even find some semi solution of that in there(that restart one it shows how bugged it was) ; ) we don't know how it is on samsung android 10 now.
On pixel 4 seems to be ok without any issue and i can't find any no outdated info about oneplus so i just assume that there is no longer a killing app problemo + i have one fr 3 days.
Even minus app killing overnight ram management on asus it's just strange at the moment I am reopening one app that should be easy in memory because i have like 3gb of free ram left but nope it's gone -.-.

I'll check Samsung Galaxy S10 with A10 tomorrow maybe.

Question is, why would you want an app that you have not used for X hours to stay in memory? All apps that need to run in the background use a service for that purpose. The rest gets killed as they should because either another app needs the memory or because is haven't been used in a long time. To my knowledge Android has been like that for ever (as opposed to windows for example, where you can completely stall without memory unless you manually kill things).

And why do i want all of them gone overnight when I am connected to charger ? Solution is easy if you wanna save your battery you have power profiles for that so you can and if you don't wanna do that you should still be able to but you cant... and there is matter of price why do i pay so much for so powerfull device when iam force to not use its hardware to full of its capabilities. You are right about android ram menagment but that i wanna kill your all apps start on android 9 apparently. There is nothing bad with cleaning some space when you need that for new apps but killing it all or killing it when you have half of ram empty its just stupid...
you can read some more in here maybe https://dontkillmyapp.com
and imagine i have 8 gb of ram that rog phone 2 can have even 12 and 6k battery if they have same problems lol its is like buying a sports hybrid car with turbo v8 engine and be forced to use only that electric motor because of fuel savings ^^
