Battery Check - Galaxy S II Q&A, Help & Troubleshooting

Hi,
is there any possibility to check battery health?
Since flashing JB 4.2.1 weeks ago battery life decreased and is getting even worse. No wakelocks, bbs is looking fine. Tried mcm's cm10.1, official cm.10.1 and Slim Bean RC2 with stock kernel, Siyah 5 and Dorimanx. With light use and less than 2 hours screen on time battery lasts one day. No big difference if reception is good or bad. Media scanner is fine too. The phone is more than one year old.

Plenty of topics on battery, use search.

All those topics are about people who are not able to setup their phones properly, but not about the physical battery

Almost every battey stats app you can download from the market can tell you battery health (very inaccurately).
If you're getting bad battery life though, the chance of it being an "unhealthy" battery are very low. Infact, on every ROM/Kernel you've listed I've had poor battery, I only get a good run on stock - there is way more to battery life than just wakelocks.

[Q] Average battery life on these developed roms?

I was just wondering on how long your battery life was, I guess when comparing to idle time. I ask because this was the main issue of mine as to why I havent flashed anything. When idle I was getting up to about 3 - 4 days of battery.
If battery life is important to you I would avoid all ROMs other than stock.
Flashing 3rd party ROMs is likely to damage you battery calibrator which causes you battery life to drain rapidly since calibration gets all screwed up.
Nobody knows specifically what is causing this serious issue but what we do know is that it happens when you flash a 3rd party ROM/Kernel.

custom roms usually use the stock kernel. what you get on your stock rom, you should get on a custom.
battery life is also subjective and variable, depending on your useage patterns, etc.

Once again... lick my butthole 5thelement. Man you really bring out the class in me tonight bro.
I've been using task650s ROM with great battery life. I did have the battery drain issue which I don't think is really ROM related but once I went through the suggested calibration on this forum everything has been great. Think I've had my Tab on for 5-6 days with it at idle through the night and earlier parts of the day and using it for internet browsing and music around the house each evening. Turned it off last night with 30-40% battery left (just a guess).

Yea I am familiar with screwed up battery life calibration on my Captivate. I was getting anywhere from 8 hours to a day and a half which was why I was asking.

Really? Hmm thats good to know, I will look into that one then if I consider flashing.
Heavy usage (a lot of browsing, notes, some games) nets me a little over a day. My usage can be heavy and nonstop.
My average is around 2 days before I have to charge. That's mostly moderate heavy. My usage is abnormal but I can say I'm happy with its battery life.
Using tasks rom and pershoots kernel.
My usage is heavy everyday so I get about 7 - 8 hours of screen time by the time I go to bed and usually I am around 30% - 35% left. I use it all day for when I am on the train or in class. Running Starburst KME at the moment but I got the same average battery life on all ROMs using stock kernel. Pershoots kernel is reliable and I could go an extra day if I wanted.
My galaxy tab got big problem on battery.Fully charged on 6am morning,airplane mode without any use,by 7pm night i left 50% battery.Baseband version P7500KWXG1 firmware upgrade from samsung kies.

yeah, battery life for the galaxy tabs seems to be pretty poor! i just can use my 10.1v (stock) for only about 3 or 4 days. just for a little bit of wifi surfing and ebook reading (wifi switches off during standby).
i really love my galaxy tab, and i hated my ipad, but regarding battery life i used to charge my ipad only once a month!!! really. and i used it exactly for the same things as my galaxy tab.
samsung promised it to have similar battery life as the ipad...one more lie from them...

[Q] battery drain in legacy 7

In the morning battery drains from 65% to 30% in a matter of minutes. Already tried unchecking all sounds and baseband is ks2. Anyone can help?
battery drain are one of the main things need to be patched up for ICS on Ace, but the developers are focusing on more important details such as camera. again ICS for ace isnt yet stable and are not advised for daily use. though i have noticed an improved battery backup on the basebrand XXKPO and i have suggested it to others as well you could try it. but then again starting from the unofficial cm7 battery backup for ace has gone bad on my opinion.
Not sure if you have posted in the right section.

Well, what I did was un-checking those sounds under the options, and that seemed to do the trick, somehow.
It's no point calibrating the battery, though. *Facepalms*
How long did the battery last on your last firmware, anyway?

i did those too, but when i woke up 30 odd % was gone..i was on infinity rom by nims11 and the battery easily lasted more than a day with moderate usage (a few calls, some messaging, surfing the web, games music)

[Q] Best ICS Rom for Battery life?

I installed the Resurrection 1.0 rom yesterday, but 30 mins web browsing this morning dropped the battery to 80%!
Which ICS SGS2 rom gets the best battery life?
It's best you try them for yourself, Just keep testing until you find one that is suitable. I personally, keep changing between CM9, WanamLite, Foxhound, Resurrection (Maybe you didn't install it correctly? Worked fine for me).
So far WanamLite is just right for me (Different ROMs have different advantages ) It's also Quite good on Battery Life.
Definitely installed ok, not much you can do wrong installing it tbh
Never heard of Wanamlite or Foxhound. Had been using Checkrom 2.3.6, but fancied trying out ICS to see what it was like.
After flashing a new ROM quite often you need to drain the battery completely and charge it a couple of times before you really get the best battery life from it.
I'd drained it last night and charged it fully, maybe I'll try it a couple more times before changing again.
Mind you shouldn't be hard draining it at this rate

80% Battery consumption after browsing for 30min doesn't sound right, out of curiosity, did you notice a sudden drop in battery life all at once or was it gradual throughout when browsing, Just asking coz I know some ROMs have an ICS bug where the battery would register wrong % values all of a sudden esp after taking it off charge, the quick fix for this is to take out the battery for about 10sec + then reinsert it.
It was gradual throughout the 30 minutes, but between stopping browsing and putting the phone away and getting into work it dropped another 8% or so down to 72% with no activity.
Might just be calibration errors. Hope so, it's a nice rom, very smooth and stable (the qualities I look for most tbh).

Cool!
Btw you can find a list of SGS 2 ROMs over here http://www.galaxys2roms.com/
quite nice to see at a glance most popluar (not all) SGS 2 ROMs.
Just try them until you find one that meets your needs.

AOKP, ICS Battery life issues..

I've been using the latest gingerbread builds and I'm having great battery life, But I notice when I use AOKP or any kind of ICS rom my battery life isnt so great..
Is there a specific kernel you people are using? and What kernel settings are working the best for you?
Thanks!

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.
While someone has reported having only 2% or 3% drain over 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.
Do you use the Facebook app? That sucker is hungry for your juice.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.
I read the Entropy thread, not much help.
Note: Wifi is off.
Maybe 3G/H+ keep toggling for sync process?
I do use facebook! haha. and I havent used better battery stats

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.

ROMs and Battery

What has been people's experience with battery life with the different ROMs? I've been on AOKP for awhile, and the battery, quite frankly, sucked compared to stock. I'm currently on PA and am getting just under stock. For me, battery life is first priority, even if there is occasional stutter. Testing battery life takes a long time, so I just wanted to see what others have been seeing. I would stay on stock, but I really want Tablet UI and real setting toggles.

Disable Google Now and see if that helps, totally did on my HOX and I've yet done it to my Nexus but I've not used it enough to actually deplete a battery yet.

You sort of want your cake and eat it too. If you want a ROM full of features and packed full of unicorn blood and the tears of leprechauns something is going to have to give and that will always be the battery life.
I use pa ...I charge my tablet every other day
Sent from my Nexus 10 using XDA Premium HD app
Stock ROM
Ktoonsez Kernel: Underclock to 1.3Ghz
Disabled: Google Now, GPS,
Freeze: all stock apps I don't use, Magazine, books, currents
Battery Life: 4 days.
I read a lot.
Don't game.
Watch videos with zero stutter.
I finally charged my tablet last night. Im at 82% in 8 hours.

I'm addicted to my tablet... I've been using it without stop for the last three hours. This are my results with Paranoidandroid:
Very similar with stock though. I think I could upload some as well.
I'm pretty sure this is stock. Not a lot of difference as I said. Both of the images are with very heavy usage, I mean, screen on all the time, but almost the lowest brightness. With the screen off I get almost no drop.
(I couldn't attach the image in the previous post)
Battery life will always be a combination of idle drain + screen on drain. THe most important is obviously how long you can actually use the tablet (screen on time), but you also need good enough idle drain to not lose hardly any charge between when you use your tablet.
The more features you add the less battery life usually is. So either keep PA so you have the tablet UI or use a ROM that is very close to stock, like the stock ROM from scrosler or Muzzy's ROM.
A kernel can also have greater effect on battery life. If you want the best battery then go with KTManta kernel. Use either PegasusQ or ktoonservative governor and add in some undervolting to lower power draw. Using this combination I was able to get over 13 hours of screen on time in 1 charge. Idle drain was about 1% every 8-9 hours.
Personally, I've found that my battery life has improved maybe 10% since running cyanogenmod. If I'm really lucky I can get 7 hours SOT. Not a huge improvement over stock, but its definitely better.
Its worth noting that I use the "performance" CPU governor, which is supposed to be a battery killer. Strangely it doesn't seem to make much difference for me though, it just makes everything quicker!

Well, it is difficult to notice a higher battery drop when it is already insane... XD. Well, according to battery widget I'm getting around 8h with the screen on, which is not bad.

I've used the "battery widget" for a very long time and that app is a battery drainer. Got way better battery life uninstalling that app.
