[Q] New S2. Battery 'break' in. - Galaxy S II Q&A, Help & Troubleshooting

How many charges before the battery is officially broken in.
Got my phone yesterdy and the battery life doesn't seem amazing as some other people have mentioned.
Im using Cognition ROM with the Kernel included with it.
Im guessing it takes afew charges for the battery to break in and reach its full potential?

I don't think the same.
For betterment of battery backup see the other battery related threads.

Yeah i used this.
Noticed something about GTALK_ASYNC_CONN
Other then that, everything seemed above board

it will take a few deep cycles for sure. i usually do a few days of deep cycles, then i start charging it whenever i feel like it and by the end of the week it is great. i keep trying the newest cognition roms (which i love) but i keep going back to cognition version 1.13 and then i flash a custom kernel cognition made and i get great battery life. your results may vary though.

Slow charging on a GB ROM....??

I'm running Gingervitis, just flashed it a couple days ago. So far I really like it but I'm noticeing some battery issues. Not sure if it's due to the ROM itself, gingerbread, or my phone.
First, it seems like the battery drain is a lot quicker that when I was running Froyo. Doesn't bother me as much I guess.
Last night I plugged my phone in at about 2:00 AM. It was at about 20%. It is now 9:30 and it is at 8:00 is was at 85% and now at 9:40 it's at 96%. Over 7 hours and not fully charged???
That seems crazy to me. The phone sat idle all night so I don't think there was any load eating up any additional power.
What is causing this?

Known issue, unknown fix afaik.
Try flashing imos latest kernal--did not do well with my phone but the charging seemed to be a lot faster IMHO.

Read my new post. Thanks n good luck! (Check your kernel)

Charging speed seems fine until it gets into the upper 90s. I've been waiting for 20 mins for it to go from 98-99 to 100 so I can finally do my battery calibration.
(Imo's latest and DasBamf GingerRemix)
Gotta love the Thunderbolt's ability to destroy a fully charged battery and take forever to recharge. I was using rooted stock and now I'm on Cyanogenmod and I haven't seen too much of a change in charge/discharge behavior.
I know this may not be the answer you are looking for but if you could go without your phone being on for an hour or so than just power it off to charge, it goes a lot quicker n.n

Charging
To address the OP and your comment......
Yes try a different kernel, Dream's new one is based off IMO's with some nice tweaks. As for charging to 90%.... thats standard for any device that utilizes quick charging. You can NOT charge a battery on fast charge all the way to 100% with out ruining the battery. Some kernels have issues with quick charging, so they disable it, others quick charge to 60% and then trickle charge.
Apple and HP were one of the first companies to throw in the quick charge method 80/20 80% quick charge @ ~1% per 1min and then trickle for the last 20%.
Hope that helps....

Thanks for the suggestion. I think I'll give it a try.
Might as well ask another question right away.... I have not been having good luck with the battery life on these new GB ROMS. I've been running Das BAMF 2.0.5 for a couple days now and it seems to not be so great on the battery. With pretty much NO usage today, my battery is already at %80.
My battery usage shows it off the charger for a little over 5 hours, and normally I'd say 5 hours and %80 isn't bad, but like I stated above, I haven't used it at all today. No texts, phone calls, or games.
Any battery improvement with Dream's kernal?
I don't know about the battery life but after you plug your phone in to charge just reboot it and it should charge fine. I read that somewhere on here and just did it this morning. Worked great for me.

I dont like recommending one ROM over another.. but there is alot of buzz over Th3oryofGinger, its got some.. but not alot to do with the ROM. Try that if you like none other. The kernel is key. Try dreams with Th3oryofGinger and see how that works. Remember to run speedtweak.sh in terminal and use the extreme setting (extremely undervolted, overclocked to 1400mhz) and then select the setting to remove limits for governor. I use interactiveX with setCPu and get decent results.
No ROM, MOD or Kernel will give you enough battery allday with normal intended use be it gaming or business. Fact is it was a crappy hardware design in that respect. With the Tbolt you should expect 1hour per 10% of battery for decent use... 10 text messages, 4 emails, and a few pages of internet searches on 3g per hour is what I consider decent use. Realistically it should last an 8 hour work day... with some to spare before you charge on the ride home. Dont expect much more.

Thanks for the suggestion! I may give Th3ory a try. I download the newest Dream kernel but before I flashed it I jumped on Imoseyon's page and found out that I was running an OLDER version on his kernel with Das BAMF. So I flashed his newest (3.0.1 test 1) and am going to try that out for a couple days and see how it is.
I do disagree with you on the fact that a phone should last a little more than an 8 hour work day. On some Froyo ROMs and kernels I was getting a least 15+ hours with minimal/medium usage.
Mine charges very slow, running liquid ginger 1.1 battery goes down faster too.

[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.

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...

Poor Battery Life on new AT&T Galaxy S II

I have the AT&T Samsung Galaxy S II phone, and it is absolutely brilliant. Speeds are excellent - no lag. Screen is absolutely AMAZING. Camera is the best I've ever touched.
BUT, the thing that bugs me is the battery life. One of the selling points of the Galaxy S II to me was the "Amazing Battery Life" which has been praised. I have only owned this phone for two days (charged only one and a half times), but I have not seen this "excellent" battery life AT ALL.
Any tips or suggestions? I have read that the battery in this device "improves" after some time (a few charge cycles). Is this true?
Thank you
hey congratulations on your new samsung. I got mine when it first came out and had the same problems with batteries. My best suggestion is to familiarize yourself with custom roms and learn everything you need to know about flashing and rooting, and when you're ready look into installing a custom rom. Cognition v1.5.1 is a really good choice because of the fact that it removes a lot of the bloatware that automatically runs when you turn the phone on (which drains the battery quite a bit). Also some other ways of dealing with the battery life is to reduce the brightness as much as you can handle (the highest setting of brightness on any phone is never a good idea for battery life).
if you search around these forums you will probably find better help from people who know more about this stuff than me. However, as someone who went from never touching android in my life to learning it all with this phone I can say your best bet is to learn how to flash and mess around with the firmware. That coupled with basic battery tips will help a lot.
also one final thought. If you download battery calibrator from the market, charge your phone to 100% then take the plug out and run it, let it drain down to 0% then start the charge over that is the quickest way to fix the battery issues. (this would only need to be done once, or every time you flash a new firmware if you choose to pursue that).
hope I helped!

[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).

Btw you can find a list of SGS 2 ROMs over here http://www.galaxys2roms.com/

[Q] KitKat/4.4.x and battery issues (regardless of the ROM)

I have been trying out various 4.4.x ROMs (CM, Resurrection Remix, SlimROM) and had varying levels of success but the one issue that I have had consistently with all of them on my SGS2 is battery. 4.4.x seems to devour my battery no matter which ROM I am using (and the different ROMS are using different kernels usual). CM11 has far and away been the most stable so I have stayed with that but it too as failed to resolve my battery issue. I have never had much luck with battery life before but half a day is ridiculous. I thought about trying a different kernel but not sure that would help as #1 I would think the CM team would know better than I what would be the optimal kernel and #2 I have been trying different kernels anyway when I have been trying different ROMS as I believe the different ROMS have all had different kernels. Has anyone else had this issue? More importantly has anyone had any luck resolving this?
I suggest you to replace your battery. Beaware from cheap ones!!! I have I9100 too, i also try many methods to increase my battery life but i reach maximum 10 hours. Then i buy new batteries. It is not original galaxy s2 batteries but i think better than the original one.(1800mAh buy from ebay) Now i use RR kit kat rom with stock kernel my mobile data is always on and I go to bed at %35 percent of batteries.
1. If your battery is quite old, replace it.
2. Check whether you are having any wakelocks. Does it go to deep sleep?
3. When you say battery life as half a day, what is your actual usage? Screen on time, Wi-Fi, 3g, calls etc?

Thanks. My battery is about 2.5 years old, its an Anker battery, 1900mAh that I bought on amazon (I honestly don't know what constitutes "old" for batteries, is 2 1/2 years old?). As for ROMS I was actually running an older version of RR but had serious stability issues (related to sdcard, never was able to resolve it) and battery wasn't great (better than now though) when I upgraded to the newest RR I had some lingering stability issues and battery issues too so just settled on CM11 this time.

I am not totally clear on wakelocks and deep sleep, I have "Battery Stats" installed (guess its not the same as the betterbatteryapp but seems to give some similar info) but its not clear to me how to read it all. In this case it sayd the stat period is 3 hours 8 minutes and out of that it has been in deep sleep 1h 51m and running time 1h 17m and wifi time 1h 25m and my batter is down to 74%, I am assuming that is not normal? In terms of applications the hogs are defintely the two audio apps poweramp and dogcatcher (they are just at the top of the list, the numbers it gives don't really make sense to me)

Well I have a 3 hour idea of my usage above, I don't use 3 g, I have wifi on about a third of the day perhaps, and actualy screen time probably just an hour or two, I do use it quite a bit for podcasts and music though. But I had tried it with my audio apps uninstalled for a few days and it still drained fairly quickly.

If your battery is 2.5 yrs old, that's almost certainly the cause of your issues. Good advice to stick to original Samsung batteries; though there's nothing wrong with the 2000mAh genuine Samsung battery Vs the 1650mAh one - I used one of these for almost two years.

Doh, was hoping I wouldn't have to replace the battery. Actually... that said. Should a 2.5 year old mostly unused 1650mah samsung battery still be good? I think I still have the factory battery around somewhere now that I think about it. When I purchased the Anker battery I seemed to remember it was mainly for price and reputation reasons, not that the Samsung battery had such a bad reputation but the Anker had such a good reputation and a pretty good price.
I will give another battery a try if you say 2.5 years is old, but I do have to admit that the battery drain was not nearly as much of an issue with the older ROM I was using (RR 4.2.x) before, it wasn't stellar but not like this so it seems to me its more than just the batter thats giving me problems here.
Anyway, my phone is still golden other than the battery issues so if i can squeeze another year and a half out of it I'd be a happy camper. Any other thoughts would be welcome (and appreciated!)
Batteries discharge over time if they're stored/not used, ideally you should charge it up to/keep it at around 60-65% every few mths if you're going to store it for that long. If you've not touched it at all in that time, it might not be able to take/hold a charge anymore because that wasn't done.
Only way you're going to find out is if you charge it & use it.
Yeah, if you ended up getting 4 yrs out of a smartphone you'd be rather happy indeed.
If you really want to satisfy yourself as to whether it is indeed the age of the battery you're currently using causing your problems, do a clean install of stock & test that for a week. If it does the same thing with stock, you'll know for definite it is the battery. I'd be very surprised if it isn't though; they're not designed to last much longer than what you've had yours if you're charging/discharging constantly.

Thats a good idea, given what you've said i don't doubt that a large part of my problem is the battery (like I said before, with the older rom it was better but not stellar) do you know where I can find a stock rom nowadays? (sorry on the ROMS page they all seem to be custom roms, or perhaps i missed something?)
Thanks!
Stock roms @ Samfirmware, get one for your carrier/country (not 4.0.4 though, anything else is fine), if there's only 4.0.4 for your carrier/country, any other stock rom will do really -I just tell people to stick to carrier/country in the first instance as these have modems bundled with them that should have been tested by the carrier to give most people on their network good connectivity most of the time.
Or, Wanam has a thread in one of the development sections (I forget which; do a search or have a rummage around) that has CWM flashable stock roms if you'd prefer to do it that way; haven't had a look at the thread for a while so not sure if links are still live, but Wanam is a very active dev & I'd be surprised if he doesn't still have them hosted somewhere.
Does it drain more at a locationw where you use a certain Wifi?
I'm asking cause wlan-rx drains are know Android phones in big open Wifis as the phones get bombarded with signals from other computers/phones and are not filtered and keeps the phone awake.
Easiest way to find out is using Betterbatterystats.
