I have had my Galaxy S2 for almost 2 years now and I'm still going with the stock battery and it have worked great but some time around the start of Novmber I rooted and installed CM 10.1 and since then it feels like my battery life have become worse.
I now run CM 11, but it's still the same with battery life or even worse.
My phone never last a full day with normal usage. Today it went from 100% to 9% in less than 5 hours with only ~37 minutes of screen on time.
Todays usage: http://i.imgur.com/Adl7YQv.png http://i.imgur.com/G80vf2e.png http://i.imgur.com/YtcqKh7.png
Also, when listening to music on Spotify (offiline playlists) it draws battery like hell, it lasts maybe 3-4 maximum of listening. And when playing games with the charger connected it drains battery faster than it charges the battery.
What could be the problem here? Would really like to fix this problem but I do not want to go back to the stock Samsung software. Please ask questions if you have to (if you need some more information or such) and I'll reply as fast as possible.

Install BetterBatteryStats (google for download link on xda) and look what's draining your phone.
Your signal is very bad, that drains battery too.

So I installed BetterBatteryStats but as I restarted my phone the stats were reset and I can only view the stats for the current session, I will monitor it again sooner and remember to not restart the phone. However, when I restarted my phone it went from about 50% to 15% instantly, how did that happen? It has happened once before while running CM 10.1 also. Could it be that the phone just showed 50% but it really was 15%?
Picture of the battery drop is in the first post as I can't post links in replies (new user under 10 posts).
Also, how would be the best way to share my BetterBatteyStats? The included share feature just left me with an .txt that's a bit hard to read.
From the screenshots i can see your phone is always in search of signal.
Change the modem or pit it on gsm network for the time being
Further, the battery drop of restart is due to chip not behaving. Or battery is dying.
Change the battery is what i advise

It's rather the other way around. I had these drops tens of times. Most of the times, if I leave my phone in deep sleep, it will go up again. So in fact the 15% is 50%(minus a percentage for rebooting).
Look what other people are posting in that thread and read the op before posting. But I think a txt file is good enough.
First try to find an explanation for this battery drain, before buying a new one.

I'm not really sure about how I "Change the modem or pit it on gsm network for the time being", if you could explain that it would be sweet.
I have only used my phone very little today as I have been distracted with other things and I slept all day so battery have been ok. I will return with results another time when I have been using my phone as I usually do.

I have monitored my phone with BetterBatteryStats for a few days now and I have posted in their thread and some people there helped me to reduce battery use from 6.3%/h to 2.0%/h in idle (on 3g with fast dormancy disabled). I uninstalled some apps and disabled sync on some other.
I have a question about Spotify also, when I play music from Spotify it seems like it uses to much battery. I use watchdog and I get alerts sometimes that it uses 40%+ cpu, that doesn't seem right does it? And when I open CPU-Z it shows that cpu is at least 20%+ in use all the time with no other program running, that doesn't seem right either. Anyone have any ideas about this?
After uninstalling Google now my battery lasts a bit longer...

First of all, DON'T buy stuff before you try going to stock rom, you can get back anytime from your nandroid backup. Battery problems are very hard to track, someone already suggested betterbatterystats, try finding it yourself with that, and if you fail you can;
1- Wipe everything and run the phone with only betterbattery stats installed and see the problem,
2- Go to stock rom and see if your problem persists without any apps installed.
Edit: If your cpu is misbehaving (even in stock), there is nothing you can do since its a hardware problem, you need to go to service centre.

I know battery has been diacussed before but i think this isnt normal. I left the office with almost full charge, listened to music on the.way with bluetoith headset for an hour. Got home and browsed for like half an hour. And here is my battery.
3 hours and the phone is almost dead. I have no apps running. I had 3g on when i left the officw and at home i used wifi.
Is this normal or should i take the.phone back for an exchange?
Regardless, i still love the phone.

btw when u return the phone what do u say exactly
Thats ridiculous man. Maybe you're battery is broken.
That said mine has just drained 35% in 3 hours with almost no usage so maybe it is just the phone.
I think there is 100% guaranteed a software problem and we need samsung to fix it.
It says you've had the display on for quite a long time, music needs the display on? Also that wifi sharing is another culprit.
It drained because you had the screen on nearly the entire time not because anything else
Unless thats a case of the 'phone staying awake' bug. You can freeze wifi sharing with titanium backup to save some juice

I too am facing the same issue battery drain from 100% to 60% in a span of 3 hours.
I am having a mediocre usage of battery with touchdown as my mail client talking to my corporate exchange. Still it doesn't warrant a drain of 40% in 3 hours.
I dont have much apps installed. Even with juice defender I am not getting better results.

You could say it's normal because if you haven't yet rooted and frozen the wifi sharing process this is the exact behavior everybody else is also having. A new phone will behave in exactly the same way if it's using the current firmware.
You can do two things.
1. root and freeze the process with titanium backup or similar.
2. wait for the next official samsung firmware which may include a fix.
The rooting process takes about 15 minutes and is not too difficult. You may or may not get in to warranty trouble in case of repair, but as I and several of my friends saw it, there really is no other way unless you want a phone with 3-4 hours of battery compared to the 19-23 hours we all get now after the freeze.
Another thing, it won't matter if wifi is turned on or off, the bug and wifi sharing process will still be there.
You will probably read around the net that several processes has to be frozen, but it really only is the "wifi sharing" one that needs to be frozen for the battery drain issue to go away.
What is the "wifi-sharing"?
Mine GS2 is a bit different from the OP's. Android OS occupied 45% while Display only 19%. And charging time is unusually long. Very long. I plugged my GS2 into PC at 9am with 30% left, and by the time I left work 6pm it only got up to 75% something. That's half a day charge.

I don't really know. But I haven't found a feature not working after the freeze. Even dlna sharing, hotspot etc.. Everything seems to be fine.
You can read more about the issue here:
http://forum.xda-developers.com/showthread.php?t=1069295
Regarding the unusual long charge time, I haven't heard about that before. It takes my phone about 3 hours to fully charge.
I can recommend this application for monitoring if the phone really sleeps when left on the table and which processes uses your juice in general. It's history based and you will be able to figure out a lot of useful stuff with it.

I'm also have a similar problem, but mine was after one hour and an half of web surfing using dolphin HD and wifi... it was full, it's now about 25% remaining... Is it normal that the dolphin browser used 39% of the battery ? It's even more than the display... !
Ps: it's actually really hot on the back of the phone, on the top, just under camera... Normal ? ? ?

Well. When you have rooted your phone, you are able to do a lot of usefull stuff:
-Freeze processes
-Disable the camera shutter sound with a simple property/text file
-Make the middle home screen the real home (like htc sense) with a simple property/text file,
-Replace camera.apk and get higher quality sound in video, actually also higher video bitrate if you want that.
-Replace talk.apk and enable the upcoming google talk with video chat
-Install chainfire3d driver to be able to play tegra2 gpu based games
...and probably a lot more, but above is the only things I've done.
Freezing means : that you lock a process you don't want to run ever. You are also able to "un-freeze" if you decide to revert.
So:
1. you root your phone
2. you install titanium backup or other application that has the "freezing" ability.
3. open the freezing app, go to the process list, find "wifi sharing", press freeze, reboot
Problem solved, "wifi-sharing" will never run again.
You want to revert: Launch titanium, go to process list, find wifi sharing, unfreeze, reboot. Everything back to where you were before.

I really don't think anything matters as I can see you have the wifi-sharing bug.
You must understand, that it's everybody with the current firmware that has this bug. You must either wait or root and freeze.
Sucking up your battery in a couple of hours and making the cpu run at full speed which makes the phone get hot is exactly what this wifi-sharing bug does.
There is absolutely no way you can change anything in the settings or say, not run dolphin browser to fix this problem. You simply have to freeze the process or wait for samsung to fix it. As long as the wifi-sharing process enters your battery usage list you have the firmware that has the problem (and it's more than one) and your doomed until you freeze or upgrade to a future firmware where the bug may be officially fixed.
Just another "wifi-sharing" discussion link:
https://code.google.com/p/android/issues/detail?id=16721
Alright then, it's just that it doesn't seem me to be that much of the battery (~20%...)
I did just freeze that process and will see once my phone is fully charged... Thanks.

isnt this pretty normal looking battery drain? most people on this forum are getting about 4 hours screen-on time, sometimes 4.5 hours. yours seems to have the screen on about 4 hours from your graph picture. isnt this normal? if it was all gaming usage it definitely would be normal...

oh, was that a constructive comment?
I know this question has been asked really lots of times, but I didn't seem to find cases similar to mine.
there doesn't seem to be any wakelock (except 2 which is incredibly short) and it was in deep sleep mode all the time. but yet, it drains almost 5% per hour which i find is really too much...
I've tried lots of firmware (litening, wamanlite, turkbey, stock, ICS) and removed all the unnecessary bloatware to reduce wakelocks to a state as shown in attachment. but still, they do not have any results, still get less than 1 day life without any usage at all...
Could this be hardware problem? I find it gets hot really fast even when i'm just facebooking.
Or is there anything else can i try to do? this device really started to disappoint me ever since the battery life looks like this.
any help will be greatly appreciated.

maybe try out BetterBatteryStats, duuno but maybe this could help?!

Try Hydrogen-ICS latest version, it seems to be "the rom" today
Battery life is very good and its overall a stable system.
Make sure to "Fix Permission" after first start, reboot recovery and do it.
Also sometimes "to much junk" in your SD card can cause battery drain, copy your files and format the SD card, you might see some diffrence. (i did)

you got 20Hrs out of your phone? grats! as of lately i've been trying alot of different roms and different customization settings from kernel tweeks to CPU tweeks (undervolting/underclocking) and im even turning off every extra setting that consumes battery power apart from wifi
on best with a 2000Mah battery i get 13 hrs on standby and 4 hrs if im playing a game - these days my phone doesnt charge anymore - it discharges even when plugged in
I recommend downloading HydrogenICS, it's good! Download Battery drain, so you can see how fast your battery is being drained.. Also, let your battery go down to 5% then charge your phone
Something is seriously wrong - you've hardly used it, looking at those graphs.
I'd try a stock anything, and if you get similar drainage send it in for repair/buy a new battery.
this is'nt normal , in sleep mode i can get 20 hours and only lose 9%
use hydrogen and neak , and try , if you get the same result so it will be hardware fault
the 3g data it kills the batt very fast,i don think u got a hardware prblm,cause 20hrs an still to go is good ive seen ppl reporting worse...dude instal better batt stat,3g watch dog but remember batt saver apps too run in bckgrnd so i suggest u stay on a stable rom wiv a custum kernel like siyah or neak an watch the batt in better batt stat.....wen i need more juice i switch to airplane mode in nite then rebot in the morning....i don hav any tweaks or uv,oc but ive seen the batt is very good wen i don use the data or wifi or download or update,pm me if any doubt......cheeeerz
You flashed different ROMs the last days? First thing is you should only flash with full battery and after flashing it needs some time (three full battery cycles e.g.) untill the battery works fine for the ROM.
And you may recallibrate your battery. Turn the mobile off and load the battery to full. Then go to CWM and reset your batterystats. Now unload till the mobile goes of and reload to full with mobile off. If you doe this for e.g. 3 times the battery should be recalibrated.
I must say Omegas ICS + Speedmod or Siyahs Kernel. Best ever. Or checkout Paradoxxxs rom very stable but for me not so good xD

bro, 20 hours is with 99% deep sleep is seriously wrong. better battery stats cant tell me nothing, since i have no wakelocks or whatever, and all those battery savers apps, they spent more battery than they can save. when those screenshot is taken, i can tell you for sure, bluetooth, gps, 3g, wifi, auto sync etc everything was turned off. even brightness is 10% (which is even lower than auto brightness settings). anyway thanks for the reply

nope, i always try at least 5-6 battery cycles after flashing to see the real graph. and i've read in this forum somewhere, calibrating battery by deleting batterystats is useless for this phone.

speedmod is a kernel like siyah rite? i've use siyah before, but it doesn't seem like much help. nonetheless, will try them ^^
thanks for all the replies and recommendation, will try different rom & update again (probably in 4-5 days for trying 2 roms
I have exactly same problem. On GB over night(7 hours), battery consumption was around 9%. On ICS more than 20%, but nobody touch phone. I try few roms: wanamlite, omega, bezke, pure. Now i have hydrogen. Better battery stats shows nothing special. Only thing what i can think is wi-fi. if i turn off seams to be better, not that dramatic, but anyway not that good like on GB.
strange...
let me ask this... what does the yellow color in the phone signal mean? anybody got any clue?
shouldn't it be green/gray ?
in my phone whenever i have green/gray in the battery view the bar hardly goes down on idle but i see a big drain compared to green/gray when it becomes yellow even in idle
let me post a pic to clarify...
i was complaining about sudden batt drop on cm9 ics, i know its 2 diff roms but still the yellow bar got my attention in both pics...
just searched google and came up with red= no signal, yellow=very bad signal to no signal, green = good signal/full
bad signal makes the phone look for the signal in a bad way using a lot of the battery...
guess i found out why my batt suddenly dropped so bad compared to the rest of the bar...
id suggest flashing a couple of modems and testing how good of a signal u get with each and sticking with the one that works for u, if its a weak signal from the provider then find a better provider that covers ur place with better reception...
start from there and then if batt life is still bad search search and search... best of luck with ur phone...
@mazroui
in those 7 hours your phone should lost 9 - 10% of battery, but not more than 20 unused, what is process causing that usage?
for me: i charged phone before sleep, when wake up after 7h i had 20% left.
Android OS - 92% , rest for cell standby, phone idle and screen. Wi-fi was setup to sleep when screen is off. Better batery stats show that wi-fi was on for almost whole time
Cell Standby and Phone Idle using that much of your power means that the signal in your area is horrible and the phone is struggling to maintain a decent connection with the towers, this can drain a tremendous amount of battery depending on how bad the signal really is, the yellow bar means it's not optimal but there is a large degree of variation between the top end and bottom end of the yellow bar spectrum. Try a different modem or move your phone to an area with better reception and see if you still get this sort of drain.
Android OS is misreported by practically every Kernel because for some reason Samsung accidentally made Screen On add to the Android OS bar, so your Android OS usage is actually AOS + Screen On, for the most part high AOS usage can be ignored as a source of drain using the phone info battery screen, I would look elsewhere for the problem. Sometimes rogue apps hide their wake locks in another wake lock, for instance if you have facebook or many of the IM programs on your system, they poll their servers a lot causing a kernel wake lock called 'svnet dormancy' (in gb) or 'multipdp' (in ics) this causes a lock of 5s to ensure proper packet transfer, if your app is requesting packets every 4 seconds, then its essentially a permanent wake lock but may not be reported as the app being the source.

There is a defect with Android where good signal strength is mis-reported on this screen as yellow, even if you have 100% signal.
Until you go to About Phone > Status, just once. Then when you go back to this screen, it will start reporting as green if you have good signal.
I've tested this out on my phone, and confirmed it... try it out yourself.
I stopped caring about it, so I just ignore it unless it gets reported as red.

If you look at the graph in the right pic you can see that the curve is less severe when WiFi is active, while this doesn't prove my point that its a network issue it does increase my suspicion that the issue is mobile data related.

Something is horribly wrong with that. Do a full wipe. If it still does that, reflash your firmware. If it STILL does that, maybe flash to a newer stock ICS firmware? Then as a last resort, you may want to go back to GB.

This guy may be onto something, actually. First thing you should try is flashing a different modem. THEN do all the stuff I said above.
EDIT: just noticed you're in Oz. Try flashing a T modem. Most Australian users report much better results with both battery and signal after doing this.
I noticed my S3 drains about 10% battery overnight. I dont think this is normal. Wifi and 3g are off, it just lies there by my bed doing nothing. Ive restarted it and no help.
Cell standby shows 41% usage. Is that right?
The 2 red circles in the screenshot show when my phone is idle just lying there.
Any help?
We need more information. What apps run? have you remove/freeze bloatware. Are you rooted? what rom are you on?
I'm going to run this based on speculation perhaps side effects of rooting your phone? I know there is no conclusive evidence of this but a hypothesis as such. My apologies if you aren't rooted.

why would rooting your phone create battery drain?
OP the standard answer is to install better battery stats and check it again to see what those wakelocks are. Once you find out why your phone is waking up you can do something about it.

I'm also getting a 10% battery drain over night. I've been putting the phone in airplane mode to see if that helps at all but it really doesn't. Anyway we can inprove this? 10% seems like a lot for sleeping...

install better battery stats and find what causes wakelocks......as above post!

thanks for the replies everyone, Im using the latest stock firmware... no rooting here...
Installing better battery stats as we speak and see what they say...
GSam Battery Monitor and / or BetterBatteryStats would be the first place as mentioned already.
I was able to find what was causing me most issues. It was some Calender storage and Google syncs (bookmarks, contacts etc) even though I didn't have them activated.
Anyway, after freezing them I now only lose 2-3% overnight. That is with gmail push, email sync every 4 hours and about 7 or 8 other Widgets updating every few hours. Mostly noticed a massive improvement when I flashed the latest siyah kernal.

I don't know but I get the feeling that rooting various phones might have hidden side effects as such, rooting your phone is still evolving as of today. There are still alot that the general doesn't know hence there are always new things about rooting although I might not be knowledgeable in that department. However is it possible to unroot your phone? rather revert it to stock? try doing that and see if there are any differences.
i like to keep my gs3 connected to wifi and muted while i'm sleeping but when i wake up i always get 8-10% battery drain (in 8 hours app), i come from a motorola atrix which in the same conditions i get no more than 2% drain over night.
i've tried many roms (omega, foxhound, ultimarom...), many kernels (stock, galaxsih, siyah, phenomenal medium and extreme...), and also some basebands (modem, radio) but i keep sticking with the XXLH1 'cause i get less drain with this one. but in any combination i always get 8-10% battery drain during night.
i've seen some of you say that you get 2-4% drain in the same context so i would like to know what am i doing wrong :/

im using the leaked stock 4.1.2 there now, and i had 3% drain in 11hrs between overnight and not using it this am.
seems v good for battery life so far. i know your pain though. its non usage time i want to be high batterylife. id expect 2-3 days from the phone when not playing games etc... im hoping this is gonna fix that now. most reports are good about battery so heres hoping.
in a few days will know more
How is it sleeping overnight? check settings > battery and check how much it's awake when the screen is off, then check better battery stats to see what is waking it up, I would probably say you have too much synced.
you're right, i have too much synced, 3 google accounts, plus facebook, twitter, whatsapp, skype and others but those are the same settings i had on my old motorola atrix and even there i got 1-2% drain, although i was on gingerbread.
i will install some battery stats application to see in details whats draining it so much, 'cause under settings it only says that idle and standby time are the draining reasons.
gonna try the leaked 4.1.2 to see if i get better results, thanks!.

Better battery stats is the best, but that is a lot to sync, I would imagine it's not sleeping well because whenever an app decides to sync it will wake the phone up, and let's not forget the S3 has a 1.4GHz quad core CPU, if it wakes and uses all cores it will drain the battery faster than a single or dual core CPU. I notice the Atrix has a 1GHz dual core, so you should expect a lot more drain especially with that much synced, honestly you shouldn't need Skype syncing unless you always want your skype contacts to be up to date in the contacts app, and Twitter just syncs to pull the latest tweets through, you can just do that manually every time you open the app.
Before 4.1.1 I got 9 hours 99% overnight no 3g or Internet, now it's 90%

does that mean that jelly bean is making you experience worse battery life?.
maybe it's because the atrix has 2 cores but if the gs3 uses all 4 cores to fetch or sync some data, that would mean it's not very well optimized for simple tasks, thanks anyway i'll try better battery stats

Android doesn't fully support multi-core CPUs yet, which is the main problem, all you can try if you need all the apps syncing is download a custom kernel and change the CPU governor this will change how the system uses the CPU and it can help.
Well for starters, Google Now should be disabled if you are concerned about battery life. Also check for and disable latitude and location reported from maps (they are getting activated by google now) Even if data/sync/gps are off google now constantly polling for updates thus draining battery.
With my HD2 running GB/Froyo for over 2 years, and methodical testing to achieve the lowest battery drain in standby (testing for 8hrs at night) the best I could do in AP mode was .35% per hour which is less than 3% over 8hrs.
I have owned and tested my S3 for 4 months and usually get 1% per hr and in AP mode....I get similar to the HD2 above at .35% per hour but I haven't tested to crazily.
I find it hard to believe and would love to be convinced, that any S3 owner can get less than 3% per hour drain without going into AP mode. Please prove me wrong and state your methods for all to learn.
Finally, I do not find the battery drain to be Linear. I am guessing that a battery charged to 100% sometimes may actually be a bit stronger than 100%. So doing a random single test may result in low drain numbers but that may be misleading. That same test performed at 20% level, may yield worse results if in fact my theory that the battery does not drain linearly...is true. But for consistency, I always perform the test at 100% battery and let it sit in the charger for an extra 2hrs before unplugging it. This way, at least the test is more consistent and more directly comparable.
I now have Green Power app installed and it is able to automatically turn off wifi/data in standby under conditions set by me, the user. I am performing some nightly drain tests. I would be thrilled if I could get between .35-.75% per hour. My first 2 nightly tests failed thanks to Slacker Radio....which held a Wakelock even though I bloody killed it!
I think this could be due to fast dormacy
http://www.androidnz.net/2012/06/at-your-own-risk-how-to-disable-fast.html?m=1 there is an app to disable this.

A bit off topic but just reminds me of my old Nokia N95 because whenever I was in a network dead spot or just have no signal for whatever reason (Gif fgaff) the battery would completely run dry within maybe 6 hours, and you'd think because it has no signal it should last longer than the few days standby I normally got.
And I've never had a SIM in any of my Android phones that lost service for long so has anyone seen this happen on an Android or is it just a Symbian thing?

When a phone has no signal it has to scan all frequencies for a signal, this constant switching of frequencies drains a lot of battery, it also increases the power to the mobile networks chip to try to pick up even a weak signal, which also drains the battery faster, it happens on all phones.

Which I am running but 3% over 11 hours?
Any e-mail accouunts? What do you have enabled/disabled? What is syncing?
The best I have ever managed was about 1%per hour and that was with everything off apart from the cell.

Read the link I posted above about fast dormacy and if this is your problem then get the app fast dormacy from play store
If you're worried about wifi while sleeping also have sync turned off and location in settings and disable notifications from play store and disable notifications from apps also

Will give it a try but I have never seen it show up in BBS in the past hence never tried it (I was aware of it) and as far as I am aware O2 (UK) does support Fast Dormancy.
It is not that I an dubious about the 3% drop over 11 hours I just want to get to the same level!
EDIT: To get the 3% drop do you disable everything you mention above? I use Tasker to disable everything including sync, wifi etc...except the cell. But I do not disable play store notifications seperately.

This is what I have come to expect. 1% per hour is reasonable and typical. 3% over 11hrs...hmmm...I don't believe it.

I have messed with this before without positive results. But anyway, since it seems like you have it working...what is your typical % drain over 8hrs?

I usually turn mine off overnight but if I do want it left on I turn my location settings off and everything that requires wifi and don't lose much.
I'd suggest trying better battery stats from play store then after leaving your phone off overnight dump your results (in settings) and then go here http://forum.xda-developers.com/showthread.php?t=1179809 to ask about your results

Okay, so i just installed CM10 (Dec 5 release) with no problems. Audio working just fine through both speakers. minor issue when connecting to bluetooth and wifi but reflashing fixed that. My issue is with the battery draining EXTREMELY FAST. Has anyone found a resolution to this?
Thanks, Jwallbanger.

first question, what do you mean by extremely fast? unless your phone is dieing in under an hr from full charge i wouldn't say its "extremely fast".. secondly there is a "discussion thread" located in the general section of the forums to talk about and find solutions to problems related to CM 10 found here, also have you checked your battery stats to see what is eating your battery away? weather its screen on time, cell standby, wifi or data... or an app.. there are several issues related to battery drain.. like if you have wifi on but not connected to a wifi location.. or having data on but in an area with no signal.. more information is needed but i would prob suggest to do a full charge to 100% wipe battery stats from recovery and then do a test from 100% to see how long your phone lasts with full usage and in full standby mode... then compare and see what is eating your battery life away...if not refer to the thread i liked earlier up in this post

Yes I mean dying in under an hr, dying while plugged in charging and all i'm doing is text messaging. And I've checked the stats, nothing different than when i was running speed rom. But thanx 4 the link to the discussion thread. maybe I'll find something there.

My suspicion is that Google now prevents the phone from sleeping normally hence affecting battery life in standby mode. However if its dying in under an hour that is quite drastic and I would suspect there might either be a rogue app running in the background (do you have the eBay app installed? I found that also contributed to awake times in cm10). Second question is how long did your battery last in speed rom? Were you getting at least 2 hours of screen on time? If you got less than 1 hour and 30 minutes of "screen on" time in speed rom with data not constantly on I would suspect your battery is failing as well. Good luck
