4.2.2 stock battery life worse?

I'm noticing that battery life is worse in 4.2.2 - I was on cm10.1 nightlies w. Cm10.1 kernel and was getting about 10 hours screen-on time before I needed to charge, but I'm getting 7 hours at best on 4.2.2 stock (rooted, bootlader locked).
I have the usual culprits turned off - Google now, location services, currents background updates etc. So I hoped I would at least get the same.
Anyone else?

I have never gotten more than 8 hours of battery life with 4.2.1, but so far on 4.2.2 I'm down to 73 with 3:30 screen time, so I guess it got better for me

Yes! I just read that. I am just about to do it now.

I can't comment on battery life, but did notice something a little alarming with regard to battery drain. Was on the couch for an hour talking to someone using viber, just plain text. No video or audio. Tablet was plugged into the wall, and after about an hour i noticed that the battery had gone from 100% to 98%. Should not be possible for a simple messaging app to cause the battery to drain faster than it can charge. screen was on auto brightness as well.

Did you look at your battery information to see what was using the most energy? Display is always far and away the highest for me, and if it was on Auto Brightness, depending on the lighting around you, it could have been running at full brightness...which would be a pretty massive drain on battery.

Once the device reaches a full charge it cuts off the power draw to avoid damaging the battery. It's normal for it to hover between 97% and 100% while still plugged in.

I barely get 6 hours of use now.

I did not look at battery usage, but the screen was generally dimmed, where as normally i have it manually set to full brightness, and nothing was running in the background that would not normally be running, that is to say nothing other than android stuff, it's basically a tablet for internet, email and skype/viber while i watch films etc on my computer

Indeed, but this has never happened before and i typically run the device with screen on maximum brightness. on 4.2.1 it would always show 100% when plugged in, i never once saw it drop to 99% or below.
So without further analysis of the issue, it could either be that something is sucking more power, which would seem odd, or that the update has brought about changes to the way the device charges, or changes to the way the device displays the battery level.

Damn guys, I don't know what I'm doing wrong, but I'm jumping around in happiness when I manage to get over 6 hours of screen time lol.

I've been on battery for the past 12+ hours with about 6 hours 15 minutes screen time and still have 36% battery left. Battery seems at least as good as on 4.2.1.

if you are rooted change your processor speed to 1.5gHz, it really helped me get better battery life
so far at 6 hours of youtube with 50% left to go

Thanks, I've done this now, and get about 5~6 hours of screen time now with around 50% left.

My battery life has gotten considerably better after updating to 4.2.2. The biggest improvement is how little the battery life drains on standby...it's nearly nonexistent.

Standby has always been great for me. With stock rooted 4.2.2 I'm getting great battery life. Loses maybe 2% after 8-10 hours idle. In constant use I'm averaging 11 hours on screen. I have everything on and synced but as I'm indoors I stick to 30% brightness. Also, I'm mostly just browsing. With games the life would be less for sure. Totally satisfied with the battery life of this tablet. If yours is getting truly bad battery life I suggest you try searching for rogue apps. After that, try a complete reflash of the stock image which deletes everything. Another thing I've found that helps performance is setting the WiFi band manually. As I have a pretty good router that utilizes both the 5 and 2.4ghz bands I set mine to 5ghz only. I live in a town house and 2.4ghz can be pretty congested even after turning my antenna power up to 150mv or greater. The 5ghz band is pretty open. I'm getting load times on webpages comparable to my i5 2500k sandy at 4.5ghz and ssd with its 5ghz WiFi n wireless card. This is the quickest rendering tablet I've ever used.
As an aside, the complete re image to stock 4.2.2 from Google might fix reboot problems as well. It seems to do wonders for people with battery and other issues on early n4s. My screen on mine is new but the hardware is from launch day.

Well, I haven't tried that, but I have heard that many people said the update can help save battery.

i just got the update i was barley able to hit 3 hours screen time lets see how this one lasts.

My battery life is significantly worse after the update. I flashed back to stock 4.2.2. It seems that the problem with mine is my tablet isn't sleeping. Android os is the highest battery user. Maps is taking a lot too. I have Google now and location services turned on so I'll try disabling those again... No rebooting though

do you mean reducing the maximum cpu clock to 1.5 ghz?

2 years later?

I think this will be a good general discussion:
Whats the battery performance like for you guys on a 2 year old phone, i know after a while the battery begins to degrade which is why im trying to see if this is the case for everyone :laugh:
Also what rom, kernel, tweaks are you using to get your current battery

1.5 years ago I easily get 6-7 hours screen on with power saving mode, for now i only get 4-5 hours with the same usage with Hurricane rom.

this phone is not two years old......

Yeah this phone is not 2 years old yet.. but aside, I love the Note 2 and don't plan on upgrading. I have 6 batteries for it, plus a external charger, so I never have to plug my phone in again. As far as UI goes, yes, it's missing some features, especially on 4.1.2 (luckily I never did the update ), but its multitasking features are kick-ass. At least for beginners. I had to tweak things to my liking, thanks to Xposed, such as default expanded notifications, Multiwindow for all apps, and such, but now that I have so much time into tweaking this phone I have no reason to upgrade.

I hardly noticed any difference between the time I purchased and now. My phone is 18 months old now.
Then again it could b me using 2 batteries and rotating the battery between uses so it doesn't degrade that fast.
But then again I'm not on stock rom. I was using miui in the past. Then regret upgrading to 4.3 which I found it too big of a hassle to downgrade to use miui again (4.1) and used hurricane rom with note3 mod installed. I tried ditto kitkat beta and rc1 but always reverted back to hurricane after a day of usage.

Mine last fine, about 5 or 6 hours of screen on.

Im getting 4+ hours screen time with average 15+ hours minimum of use .
this is on 4.3 stock rooted and AGNi kernel set to extreme battery saver.
normally charge phone when still at 20%.
On stock 4.3 I was getting best 14 hours.

thats minimum because when playing clash of clans all day in a marathon to collect lute really kills battery. With norman use easy get 18+ hours easy.
I also de blotted my stock 4.3. Eitherway better battery than before.

I was stock rom and after numerous useless updates from samsung my battery wont last even 12 hours. I moved to xperized rom and even then battery backup was less. I have just switched to SuperBeam and I am seeing an improvement. will post detailed update later. right now getting near 14 hours with 3-4 hours screen time with wifi and bluetooth constantly on.

Hmm yeah thats what i get too here and there depends on if i play games or not which i rarely do! Im trying out Omega rom v27 4.4 atm and testing the battery for a couple of days :fingers-crossed:

really guys only 6-7 hours? I go at least 10-12 hours, yeah of course it depends how much you use it for example when I use 3G and Wifi Hotspot simultaneously the battery drains like 1 second for 1%. I recommend you guys to install WakeLock Detector app. This app will tell you which app drain your battery, and guys, remove the facebook app as soon as possible it was on the top of the list.

My battery life is steadily declining. Still getting by the day, but not easily like it previously was. Hopefully it'll last until the Note 4 hits.

Is there an app out there that can accurate measure the battery of your phone?

There are tons of battery app , there is one that comes with CleanMaster app hope that should be good as cleanmaster is good app

I get 2 hours and 30 min with screen on and 5 hours with the phone off the charger and on 3g and 2 hours with screen on and 4 hours on 4g with screen on with stock 4.3 and custom roms and i get 7 hours with the on wifi and 2 hours 30 min with the screen on that is with good signal and on Telstra.
Apps i am using are facebook and facebook messenger and pocket cast and google apps that is all on 3g
I've only had the Phone since 16th of January 2013 and that is with two battery as well

After 1 year 2 months of usage, my note 2 lives around 7 hours screen on for wifi and 5 hours screen on for 3G

Horrible battery life on S3

Hello guys i have been facing absolutely horrible battery life on my s3 i9300 for the past 3 months or so....im currently running archidroid 2 which has absolutely amazing battery life as compared to the other roms that i have used and by that i mean almost all the popular roms that have been made for the s3 i9300 i have changed chargers....i just got a new battery about an hour ago and thats also not helping me at all i lose 2 percent in every 5 mins while doing light tasks like writing this thread and 2 percent in every 3 mins while playing games like clash of clans /fifa 14 ....one of my friends who has an s3 has abolutely amazing battery life he says he loses just 5 percent in one hour of fifa 14 i have disabled sync put my phone on 2g brightness on auto greenified almost all apps...pls help :'(

Yeah, those friends xD. On s3 you can play for about 3-4 hours depending on game. You must take care of screen on time. Look at it on yours friend phone Thats the real time of using your smartphone. Max screen on time that i had was about 5.5h but I was only reading a book. And the 3g browsing eats your battery like a boss I discharged my phone in 2h so thats normal.
Peace

Use BetterBatteryStats to have full control over it. Also, I don't know what apps you have running, but try to use Greenify.
You're running a custom rom, so the culprit can be the kernel too. Use an untouched stock kernel if you want or heavily tweak the custom one you're using.
We can't tell you more than this, because we don't know what you have installed, what you have running and how do you use it.

check out BetterBatteryStats, as already mentioned for the real battery killers.
put down the brightness to a low level
turn off your mobile internet in moments you dont really need it (i.e. during sports). just like you turn off wifi, when you leave your house

Is your phone 2 years old?
Buy a new battery.

try calibrate battery or boeffla kernel

Looks like your battery needs to be recalibrated.
Completely drained your battery & charge it for 8 hours without stopping during the night.
It happened to me too a few weeks ago when I bought a new battery.
Use BBS, greenify & tweaks your kernel settings will definitely help too.
Good luck

I still like the look of the S2

Replace your battery
Either get another Samsung battery - or go big and get ZeroLemon 7000mAh - worth every penny! and you get used to the size & weight pretty fast.

[Q] Battery drainige on ALL custom roms \ kernels ever tried since 2011

Hello
i'm new here, but not new in ways of flashing and rooting and stuff.
My main problem i'm stuck at for over 4 years
Galaxy S2 i9100
Galaxy S3 i9300
Galaxy Note 2
Galaxy S4 LTE i9505
Galaxy S4 LTE T-Mobile (Netherlands) GT-i9505
BATTERY DRAIN ON EVERY CUSTOM ROM\KERNEL EVER
Let's go:
Samsung Galaxy S4 T-Mobile GT-i9505 (NO NOT THE SGH-i337, I DONT LIVE IN AMERICA)
Whatever ROM \ Kernel i tried: DRAIN
Kernel : Any
Location off
bluetooth off
signal strengt: Lived almost under a cell tower, 100 percent signal
Airplane mode, wont make a difference
Sync off (ALL SYNC)
New battery : Not resolving anything
Wipe? I could wipe for billion times wont solve ****
Brightness low - (auto disabled)
Disabled automatic time
disabled google maps log report + Disabled the whole app
Disabled auto update play store
disabled virbration
disabled touch sounds
disabled automatic wifi scan
Removing SD Card : Nope not solving anything
Trying different roms? : I tried all possibilitys
Calibrated battery? Check no solve
"Settle the rom (bull**** but was worth trying) No solve
Replaced model??Check! No solve
Gsam Battery monitor? Check, Not a drastic drain...??
Undervolting, .. nope
underclocking,,, nope
powersave governe? nope
Using 2g as priimary network? you can already guess it
Average battery 100-0 5 - 6 hours. When using losing 2 percent in 3 minutes average, playing simple games (COC) 30 percent in 10 mins
The solution to get normal battery back?? TOUCHWIZ STOCK (EVEN CUSTOM BASED TWROMS DRAIN)
So my phone lasts longer, if it only has 500 mb ram left instead of 1.3 gb (wich was on custom)
Battery goes longer with bloatware from samsung + tmobile running in the background
Its like if you drive 200 kilometers per hour on max rpm using less gasoline then driving eco mode on low rpm.
IM SICK OF IT FOR OVER 4 BLOODY YEARS ALL THE SAME BULLS*T
ANY HELP IS MUUUUUUCH APPRECIATED
THANKS IN ADVANCE
YOU GUYS R AWESOME!!
PEACE!

Custom roms don't have the same battery life as stock roms, true.
But what you're describing is clearly not normal. Last time I charged my phone was 18 hours ago. I'm now at 75% percent. There was some moderate usage (mostly texting) but the phone was mostly idle.

Well the only constant factor is you. I think you just expect to much of a smartphone. A screen on time of 2-4 hours is normal. Also it's common to charge it every night.

Maybe it has something to do with root. Since it happens only on rooted roms.
I can't find any explanation why you have good battery life on stock but bad battery life on any custom rom.

What is your SOT ?

im getting arround 3:15 ,3:15 hours and its so awefull , how much do you get and what to do ?

You'll find that SOT will be a wide range without at least some defined criteria to follow. While usage (games and videos will simply murder battery) and cell coverage will play a huge role in the disparity, you'll also find a difference based on other factors like ROM (stock vs. AOSP/CM), kernel, time off the charger, phone's % awake time, etc. With all that said, 3-4 hrs seems to be the avg for many users who run AOSP/CM, have bad cell coverage, or otherwise poorly optimized phones. Those who do some optimizing (Greenify, Amplify, custom kernel, etc.) will find 4-5 hrs on avg. Those who do some heavy optimizing with their phone may find 5-6 hrs.

Thank you for replying , do you have any tips on optimization , im on stock 6.0.1 rooted , no kernel (i tried to install franken but couldnt make the wifi work)

I managed to get 7hs, but once. It really depends on your usage. My Pure is pretty much modified (lowered resolution, underclocked, limited cores, using mods and apps).

well, might be 12-16 hour for normal use

stock kernel with 5core offline during screen off

I have my Moto X Style since a month now. I use Greenify to shut down apps when the phone is about to rest for a few hours while I'm working. I'm not rooted, so completely stock.
I don't have a screen on time, but think the battery is far to be so bad. Coming from an Alcatel OneTouch Idol 3 5.5, the Moto X Style (or Pure Edition) battery is better. And the fact that with a power charger it charges so quickly (70 minutes or so), battery is not an issue at all for me so far.
Phone is quick and great and I think the camera does a killer job, better than I thought it would. Screen is awesome as well.

what are your cpu settings and all that?

4-5 hours on stock MM

Best I've ever gotten, the phone shutdown less than a minute after this screenshot... Just over 10 hours of use, including about an hour and a half of airplane mode, and nearly 4.5 hours screen on time. This took keeping brightness way down and I was lucky not to have poor signal during the entire time.
Sad part is this seems impressive for this device... I came from a Moto G 2015 and it would go 18 hours of use with 6-7 hours of SOT easily, or a more typical day of 3.5-4 hours SOT over 16 hours of use and around 50% battery remaining. I never really worried about battery life on that device like I do now.
Seriously debating on going back, selling my MXPE well it still has decent value, and either grabbing a G4 or waiting for the new Nexus devices.
