The "all of the sudden" battery fix on ICS

I have been using my s2 only 1 day on GB so i cant really tell you was the battery life good or bad there, but i i have some news for ICS
stock ROM users.
I was actually really depressed by the ICS battery life (i upgraded from GB same day i bought brand new S2), battery life was terrible,
turning on/off syncing, mobile data, gps etc etc helped a bit, but not that much. i still couldent get full day out of it with moderate use.
Again, im on stock 4.0.3 atm.
And then, a miracle.
Let me say right away, i am aware that these types of batterys (i have stock one btw) dont react on this whole "fully discharge then recharge" thing, but i do think now Android ICS as a system does! Cuz it was exactly what i did-i said what the heck doesent hurt to try and i was playing games like crazy when battery was on 10 or less percent so it wld shut down. then, i connected charger and used as normal on charger until it was fully juiced. repeated 3-4 times and what do you know... i now get 50% OR MORE WITH THE SAME BATTERY!
I am not really sure what happend there. Did battery gauge reset? Did ICS "learned" my battery properly? I dont know. All i know is that i am now able to get trough whole day (i get up 7:00AM, go to sleep round 01:00) with only 1 full charge. I dont even bother turning off wifi sometimes when i go out and dont need it.
I have been also reading around the web that some people got the same result. No calibration trys,pulling battery etc etc...just let it go trough few cycles and let system/phone "calibrate by itself".
Not exactly sure if this is a solution, bug, feature or whatever. I just thought it was worth writing to you guys
cheers, loop

why dont u share some screenshots

np mate, but in evening or tomo morning when i come home

Well, you actually shortened your battery life span by draining your battery to nothing, you should probably google what happens when you drain lithium batteries, and how it affects capacity, and not just
dont react on this whole "fully discharge then recharge" thing

You probably did reset your fuel gauge as your phone had no power to hold the gage memory, but you could of saved yourself a lot of battery capacity, by using search and finding out how to reset the battery gauge on the Samsung galaxy s2. Hint* search extweaks and Siyah kernel.
Anyway at least other people who read this, hopefully learn and do it all the easiest and battery efficient way and not

Hope this helped, and for future reference do not drain lithium batteries, whether it is your phone, laptop, ps3 controller. Try not to get it under 50% for the best efficiency, but the more you drain it to minimum charge the faster it degrades.

Did you uninstall anything? Did you change any settings? Sounds to me like wakelocks that were removed more than ICS "learning" your battery.

Take it like this: i upgraded to ICS over GB and did full wipe. First day i installed lets say 20+ apps that i use. mostly utilities,few games.
In this period of "recovery" i only updated few apps, installed GTAIII and Flipboard.
Let me make this perfeclty clear as i stated in OP and as deniso wrote: i am aware of todays batterys and how do they work. i am not senior android user but i know my way around,so as i stated, i know i dident "FIX" the battery itself. But i still think the main problem here is not the battery itself,its how ICS uses it.
However this:
Try not to get it under 50% for the best efficiency

is just... funny. "try not to" ok i get it, but below 50% is when u need your phone the most, should i carry a portable generator with me? no offense.
Please, do not throw rocks at me. I am aware what i wrote, and i am aware that it doesent makes sense with todays batterys and smartphones.
however,i still do have my better battery life, whatever u say or dont say.
Ill make some screenies when i come home.
Ty all for your feedback.

I said TRY not to, I personally use my phone all day and my battery only gets down to about 75% -85% at the end of the day, so it takes nothing special for our phones, unless you do heavy gaming or movie watching all the time.
And what I said, which wasn't throwing rocks at you, is that you probably just reset your fuel gauge as there was a lack of power to the memory chip, and like I said in my first post, Search EXTWEAKS and Siyah kernel as they have that exact function in them which does not require you to drain your battery below critical values or at all.

hello again, just posting screenies that i promised

(its in croatian,but you can see what is important)
So as i said before. This is roughly really 50% MORE then what i was getting first few days on ICS. now, i dont know still if this is very good or average, but
it gets me trough day for sure. As u can see, i posted "screen on" time, cuz i was not getting even half of that before and i still have 34% left!
The day was filled with 5-6 emails, i watched 4 youtube videos, did cca 29 mins on surfing and cca 30-35mins in plants vs zombies. few sms, few calls.
So, im not playin smart here or anything, i just have more batter with whatever i did, and it makes me happy
Cheers

You getting more battery after 3 days could quite simply be due to the fact that you flashed new firmware and it always takes a few days for the kernel and modem to 'settle in'. You will never get a true indication of battery drain straight after flashing firmware.
And to the guy above who said he can use his phone the whole day and it never falls below 75%, wow!
I would love to know what firmware, kernel/modem combo you're using.

Really bad battery life

My device has been completely stock running ART kitkat.
Battery life has been really bad the last few weeks. (Possibly due to 4.4.4?)
I have switched off location services, Google now, and only sync gmail.
I can only squeeze out around 2 hours and 30 minutes max compared to 4 hours 30 I was able to before. (Same settings, flight mode WiFi only)
Any one have any advice please? How can I monitor and see what's draining? I've tried a a few apps but I can't find anything.
Thank you.

None taken.
I may be a recognised contributor, however in the last 18 months I've lost my interest in mobile technology, and hence I have little knowledge on mobile tech today.
I consider myself a "normal user" now. I just use my phone as it is as a regular user completely stock and I don't know these tech things anymore.
Any help is appreciated, any other info I can give? I'm rather incline not to factory reset my phone.

App sucker screen if this helps?
So daily mail is the cause?

It is the usage that drains your battery life. If fact daily mail online doesnt drain so much. I dont know, how much and how often you use your phone and that is what really matters.
What really drains batterie (and most people dont know this) is waking up your device often. When you wake up your device all cores goes to max frequency before turning down slowly. By 4 cores it drains a lot of energy. The second is the screen brightness. The brighter the screen, the more it drains. An than there are many other factors like signal strength and quality, apps...
So to sum it up, it is your usage behavior that influence your battery life. To compare I am on cm11 with matr1x kernel, do alot of surfing, chatting, listening to music and the average screen on time is 4 hours. You may try it out.

Thanks mate, appreciated.
I forgot to post my brightness.
I usually have my phone on flight mode at home and WiFi signal a minimum of 3 bars. (Excuse the screenshot which is an exception)
I suppose with my phone I do always switch it on and off multiple times, however I haven't had this battery drainage problem in the past, it only occurred in the last few weeks and I have the same usage pattern. I suspect it was the 4.4.3/4.4.4 update because prior to that battery was fine.
Thanks for the suggestion of the ROM, however I'm planning to keep my device stock and I still haven't factory reseted it since day 1 (August 2013) and hope I do not need to.
Thanks all the same.
Open to more suggestions many thanks to everyone.

Install Greenify and hibernate Daily Mail Online. It's the one draining your battery I guess.
Greenify works without root, but if I remember correctly you need to hibernate apps manually.

I quit.

I f÷׶ing quit.
I've been using this galaxy s2 for months but I quit.
Enough, simply enough.
This thing's battery life is so poor its just unusable. Rebooting the device makes me lose half the battery, and I can't fix it.
I really like this phone for it's performance but except for that it sucks. I've been trying to fix this for months but I cant get it working. No matter which ROM or which kernel, a full battery can't even hold one single evening of reading 9gag. (It survives just a hour, maybe a little more...)

The drop in the middle is a reboot
I've not used the phone all day, but at the second I touch it it drains from 70% to 10% in not even a hour, only app running was 9gag. It does NEVER survive a school day, no longer than 1/1.5 hour screen on time... The battery in it is brand new, and I even had it replaced twice by Samsung.
I'm sorry all, I'm taking my iphone with me tomorrow. This is no more fun.

You obviosly have media scanner issue, since sdcard is the first one listed. Install BBS for more info, but I'm sure it's media scanner. It can be fixed quite easily though.
About losing half of the battery when you reboot, it's a KK's bug on S2.(That is KK you're using, right ? ) It is annoying, but can be solved. Just plug it into charger, reboot to recovery, and then reboot the recovery itself. Battery percentage should fill up.
And at the end, you should't have rooted and installed a custom ROM(s) if you can't solve a simple problems like this.
With sammy based ROMs, you wouldn't have had those issues, but KK based ROMs are not perfect, so either deal with it, or simply don't use them.

You certainly have a problem with the mediascanner... A clean install would probably fix it...

Yeah, this bug used to happen to me a lot, a clean install would fix it, also maybe try a new rom? I've been on PACman since 4.2.2 and it's amazing=p
The battery is really good. Maybe try SetCPU as an app? - It's really good

Its some time later now, tried all of it, still no improvement

You have some serious sh*t going on your phone, dude...
I am browsing 9GAG also on my S2, and I can survive 2 Hours straight PLUS listening to music PLUS using Viper4Android (High Quality Sound Applied)... And has an extra 30 minutes to spare!
It's either something badass app running on your Background, or your Battery is just weak...

Dude... Just use BetterBatteryStats! Or GSM Battery Monitor to see what Apps are eating your extra battery juices!
I also recommend you to stick to Stock-JB-based ROMs (like NeatROM JB), since it's one of the Custom Stock ROMs that's gonna give you a longer-lasting battery. I recommend NeatROM since it's packed with Apolo Kernel, which also a good kernel for battery!
I use SlimSaber KitKat by fusionjack, since I want features. But if you want to enjoy more Screen-ON time with your S2, better get NeatROM :good:

Tell me what this is:
A simple reboot causes major battery loss.
And its HELL annoying

That's the bug on every KitKat based ROM, I already told you. You haven't actually lost your battery p
ercentage, it's just showing wrong informations.
Just reboot to recovery with your phone plugged into the charger, and then reboot the recovery itself, and your battery should fill up.
And install BetterBatteryStats, let your phone idle during the night, and post the log here, so we can tell you if there's anything specific draining your battery.

Fuel gauge chip problem. I have that bug even on stock rom.

I apologize then, didn't know it happens even on stock ROMs.

It won't even boot up today, it turns on and immediately gives 0% battery and shuts of again, it was fully charged for sure.
I don't have the time right now to try and get it work again. I'll just use my iPhone...

Have you tried checking your battery?

Okay, today my phone completely died. It won't stay on for longer than 10 minutes, after that the screen starts to flicker and the phone shuts off.
I already tried to reflash stock rom, but the problem stays there.
I tried a battery from a friend's S2, that was confirmed working in his phone, my phone simply won' t stay on.

My battery is dismal on 8.0. Can anyone help?

Now. This is bad.

Ugh. I need some assistance. I've done all I can to maximize battery life, but my phone is just not going to cooperate. According to battery apps my battery is healthy, but you have got to be kidding me. Look at this. It's quite terrible.

Is that like 1 hour into a new rom or something...looks like you have no battery stats to go by. Plus if your stock 8.0 stand by is horrible... Flash a custom kernel and underclock the large cores...that has really changed my battery life.

It is just a few hours after turning on my device. I will record my battery percentage throughout the day and repost a new image. It's pretty dreadful

Check your battery capacity with a program like Accubattery like everybody else does. Have you not read the 25 or so other battery threads here on the exact same topic? Step #1. Test your battery!

Gsam battery can offer some good battery stats as well. You will want to enable ADB on your 6P and then you can enable more stats in Gsam. ( google Gsam enable more stats)
What helped my battery life was turning off bluetooth scanning ( search bluetooth scanning in settings). Gsam was showing a bluetooth wakelock using a lot of battery.

I probably should have stated that I have done this and attempted to root and use gsam and the like to disable wakelocks, and mess around with alarms and services. No increase of screen-on time.

I put in a new battery and with stock 8.0 it was about 2.5 sot. Got rid of stock kernel and started tweaking some things and get like 4 sot. I don't really trust the battery apps. They have done nothing for me

PS. Any suggestions for a custom kernal?

I'm stock 8.0 ATM using ElementalX
I underclocked the big cores to 1500 /small leave stock at 1500
Leave off all the gestures to wake
Also turn off WiFi and Bluetooth scanning
I turn off location until I need it and keep brightness at 50%
If that doesn't help u prbly should replace ur battery
I bought a new back when I did my battery... it was pretty easy.
About 40 $ total..that's battery and back with new glass and bottom trim
If you do it urself just use suction to separate the body from the screen and watch out for the display ribbon under the center of the battery

What's up with the terrible battery drain when idling?

I've had the RN7 for like 2 months or so. My previous phone was a Samsung Galaxy S5 which I liked quite a lot & ran Lineage 16 on it for the last 3 years. On that ROM I got used to having literally 1% of battery drained on idle at max & could leave the phone on the last percent of battery left for 12h & it wouldn't turn off. Now, being on the RN7, things are different... I'm on a 3rd ROM (Syberia -> LOS 16 by lmc -> LOS 16 by AmulyaX) by now & have to say that even compared to MIUI, the idle battery drain is just... abysmal. How is it possible for a phone with a 4000mAh battery to drain 7-8% of charge during less than 10h idle where a phone with a 2800mAh battery could literally last half a day. Because of that, my overall SOT also takes a hit as on MIUI I was easily able to achieve 8-10h SOT, where on LOS or any other ROM I struggle to get 7h. Am I doing something wrong? Are all the ROMs for phone just straight up trash? Is there some bad omen acting on me? I just want an answer to why the battery drain during idling is so awful... That's just straight up unacceptable.
P. S. No, I do NOT care about undervolting/underclocking the CPU or GPU as I never had to do that on my previous phone.

I was also thinking about that. I see many people claiming like 11+ hours sot on this phone (custom roms and stock) but I can barely reach 7h. My last phone had a 3500mAh battery and would last a full day of use, but this one with 4000mAh makes me look for a charger during the day. Really weird.

Same here. Actually i had the same disappointment with my redmi note 4 i had previously. My old phone with 2300 mah battery lasted much longer. With both redmis my battery is dead at the end of second day with 3-4 hours of SoT

So... Few days have passed since the last post & in the mean time I charged my phone like 3 or 4 times. In the last few days I noticed something curious regarding the battery idle issue. I lost root like 2 or 3 days ago & from that time I noticed that the battery idle drain has DRAMATICALLY improved. It seems that somehow having Magisk causes battery drain (could it be related to the System On Root thing on our phone)? It could just be a coincidence that this happened at the same time, but from when it happened, my phone hardly drained a single % of battery when idling & I was actually surprised. Personally, I don't really need root anymore as I don't use apps that need it other than starting them for the first time to i.e. restore my apps backups.
Hopefully someone will do something with that info & maybe will solve the idle battery drain issue

I have the latest Atom ROM and the battery drain is ok! After two days i install magisk just for root and I clearly see the battery drain is a little bit more high !

Did you unroot your phone while using custom rom or turned to stock rom bcoz I'm planning to install pixel experience custom rom and does it have any battery issues?

In my experience battery performance in PE 10 is the same as in MIUI 11. I only need to go for the charger for like, once a day. Even with Magisk installed.

I've played around with the CPU settings in Kernel Adiutor like 2 days ago & then used my phone the way I always do. From the "results" I've gathered, it seems like my combinations of settings has made the phone enter deep sleep where as before that state was unused (as reported by KA). I probably didn't discover anything ground breaking or revolutionary, but with the settings I've changed, I still have the same performance as well as good battery life & great idle (literally 0-1% drain over night even with apps running in the background).
I will list just the settings I've changed in Kernel Adiutor to not spend a lot of time on writing each separate option for no reason.
CPU:
Big governor: interactive (you may fiddle around with it if you want to)
LITTLE governor: powersave
boost input interval: 0ms
CPU hotplug:
Minimum CPUs big: 1
I/O Scheduler:
Internal Storage scheduler: noop
Virtual memory:
Z-RAM Disksize: 2040MB
Now, as I said, I'm sure these values aren't revolutionary & my issues may have went away on their own, but you can always try for yourself & report back if anything changed (don't forget to save your current settings)
