Any Singapore users here with rooted/custom ROM'd S2 still experiencing heavy battery drain with fairly normal usage (occasional web browsing and playing games, maybe 3-5 photos - battery dead in less than 8 hours?).
I've noticed that here in SG, my 3G signal keeps on going off and on, as if the phone is constantly trying to reconnect to a 3G signal (SingTel has been pretty bad for me, especially while walking around town). I've turned it off to 2G only and my battery seems to have improved.
Anyone else in SG have suggestions on how to improve battery life?
Although old thread, for anyone who like to have an app to auto toggle 3G in a set interval check this review:

3G is the suspect zero!!!
3G is definitely the suspect zero for your battery drain....

Im from SG dude my phone can last for 16hours with 3h-4h screen on. Its pretty decent. Change your modem. Im on LPX. Dont use FB app if you are using one. Its a huge battery drainer. Use BBS to find out what else is keeping your phone awake/draining your battery.

How the heck you get so good battery life O_O max for me with UV and UC is 14hrs 2.5hrs screen time.................... If you are on stock rom then that is also a suspect, Official 4.0.3 has horrible battery life

I have a Telus S3 and I must say for a 2100 mah battery, I can't event get a day out of it which I am very surprised because all the reviews were raving about battery.
What battery life is everyone else getting? I am thinking on swapping out but wanted to ask users first.

I have the same issue, battery runs out in less than a day with minimal browsing usage. It also charges extremely slow as well.
Battery stats shows that Cell Standby is the top hog. I know there's a thread on that already and apparently it's just a 'miscalculation' but I want to see if anyone else is having the same issue.

Are the reviews your reading is on the International model? If so, of course the battery life would be better because it doesn't support LTE. LTE drains the battery big time.
Are you using LTE or HSPA?

If it isn't a bug or a rebel app draining your battery then it must be the LTE. I'm using my SGH-T999V on Wind's network and the battery life is incredible. I get at least 24 hours per charge with moderate use.
Same here - in Ottawa - using the SGS3 - LTE.
I am "lucky" if I get 4-5 hours out of the battery - even when I am almost (not even "using" it).
It drains super fast.
I, too have wondered why there are some that rave about how great the battery life is, yet there are also those of us out here whose experience is just the opposite - in that the battery drain/life is ABYSMAL.
What's going on ?
Was there a bad "batch" from the factory ?
Are there some bad batches of batteries ?
Does LTE have something to do with it ?
Is the reported "standby info" the issue - in that it is not only the reporting of what is being used, but that it is actually using a ton of the battery power somehow ?
I have not found any answers out there yet.
I too am experiencing poor battery life. I'm using a Samsung Galaxy S3 in British Columbia and am with Telus.
I'm lucky to get 8 hours with what I would consider relatively light use i.e. moderate texting, brief web browsing and no gaming.
I've done all the suggested tweaks to improve battery life such as turn wifi/bt off, sync off, power save on, screen brightness low, disabled many background apps, Haptic off, motion off, only one weather widget going etc etc. I've basically disabled every fun feature on this phone off and still get miserable battery life.
I'm going to turn LTE off today and switch to the GSM/HSPA Auto mode only and see what kind of difference this makes.
Maybe others could follow suit and post some results?
Let's sort this out. I bought this thing because initial reports had great reviews on battery life.
Cheers.
I was getting horrible battery life as well, so I left all the fun stuff on except for disabling LTE. With LTE enabled, I was losing about 10% per hour with very low use. With LTE off, I'm losing about 1% /hour. I only made the change around noon EST, but it made a very big difference right away.
I should note that I'm in downtown Toronto, with full signal strength. Checking the battery screen shows that Cell Standby is what used 42% of my battery so far today.

It's only been a couple of hours but I'm getting the same results. With LTE off I'm seeing roughly a 1% drop in battery per hour down from about 10% with LTE on.
Lame.
There are a few problems floating around but if you did some research you would find that using better battery stats app will help you find what exactly is killing your battery life.
Anyways, apparently there's one particularly nasty bug where whenever you touch your screen (even when locked) it will wake and prevent it from going into deep sleep.
https://github.com/asksven/BetterBatteryStats-Knowledge-Base/wiki/AudioOut_1
Menu -> Sounds -> uncheck "Touch Sounds", uncheck "Screen lock Sounds"
Look at your battery info screen and see exactly what is draining your battery the most.
I am at 92% with 2h 11m 41s on battery. screen takes up 51% of that drain. At that rate my phone will last 27.5 hours.

Another problem is the cell standby % is wrong by a factor of 10. Either apply the cell standby fix for rooted phones or divide the % by 10 to get the actual drain.

I did read about that bug a little bit when I was originally looking for info; but it was my understanding that it affects the reported usage by cell standby, not the actual battery remaining.
Is that not the case? Does the bug also affect the reported overall battery remaining? Also, I don't remember seeing anything about it affecting Canadian GS3s, only the international models. But I didn't look very hard at that, so I may be completely incorrect.
I'm just reaching 15 hours with 3.5 hours screen on,, 26% battery left.
same here in europe, no LTE here, i'm on HSDPA...i may be wrong but my baterry lasted first few days for 20 hours, than after firmware update maybe 10 with minimum use or 6 with normal usage....
expect solution soon or replacing it...

terrible battery
i was hoping people were having the same problem as me. 2nd day using my verizon sgs3 and right now 55% 4hrs and 10min. I hate this. Hope there is an easy solution or im going to have to take it back. Maybe i should drain the battery to 0 cuz i didn't last night and it might not be calibrated correctly yet...what do you guys think?
unplugging at 6.45 am, going to bed at 11.30pm I still had 17% left the day before yesterday. After some heavy use yesterday I only got to about 8.30pm before I was asking to be charged again.
Pretty happy over all. I think I'll comfortably get a day out of it once I stop obsessing with it
Turning off LTE has made a huge difference in battery life, dropping down around 1-2% per hour in standby.

I am using LTE when in the service area. I have installed Easy Battery Save and I must say it has helped on intelligent power saving mode but I mean why should we have to use a battery app to utilize this? Any other fixes without using the app that people have come across?
I get 40% left from a day starting at 7am full charge and ending 11pm on wind version . Using lots of email, Facebook, what's app, browsing and YouTube. I find turning sync off and on only when you need to sync helps a lot

Battery life on my Deb seems to be abysmal....
~4000 mAh battery with primarily WiFi use and occasional 3G should give at least 6-7 hours of screen on time.
Instead, I have max SOT at 5½ hours.
I'm currently rooted on KRT16O, using ART and Greenify. Attached my stats.
Please share your stats, along with any tweaks you use to leech out some more juice...

Your deep sleep is only 17 minutes. Check partial wakelock from the pulldown menu to see what processes are keeping it from conserving power. It could be an app or widget you're running. Sometimes a reboot will clear out issues as well.

It really depends on brightness, during the day the display uses more energy, even more in sunlight
I have the international unlocked exynos variant of the Galaxy s7 Edge running on AT&T in the U.S. I am also running the Renovate Release 1 ROM. Every time I check my battery usage, it reports cell standby has used the most of my battery, with screen coming in second place with much lower battery consumption. Is there any steps I can take to reduce this consumption?? Thanks

If you don't use your phone much then Cell Standby will be #1.

I really use my phone a lot during the day though. I seem to get battery drain of about 4% per hour when my phone isn't being used. I have no rogue apps ruining in the background or anything and "cell standby" always seems to be the only major battery drainer.

I have basically the same issue. I loose 2-4% per hour when not using the phone. AOD is running, so I know I will loose some battery life, but the cell standby is 45% , android 20% and google 17%. I have turned off most of the google stuff, so I will monitor that...I do have my phone on 4g, so I know it will eat more battery.....I still do get at least 26 hours out of a full charge

It's funny because I have AOD turned off at all times... I don't get what is wrong. I mean the battery life is still much better than most any other phone for me but it could be even better.

I usually have strong signal in most areas, but there are areas I have spotty signal. However, at work my phone gets great reception but I will pick it up after idle for many hours and have loads of cell standby drain. Is there an issue with VoLTE or something since ATT versions give an option to turn it off, but international models do not?
Sent from my SM-G935F using XDA-Developers mobile app
I would doubt itd issues with volte since the exynos simply doesn't have it, maybe your missing some LTE bands in your area, did u have this issue when u were on stock ROM? I'm curious myself because the main reason I didn't go with international version was concern for signal strength/cell drain, I use to have a international z4 andy reception was always worse than my wife's att phone
Fixed Cell Standby battery drain on my ATT S7.
Settings, connections, mobile networks, mobile data
Disable enhanced LTE services, then restart.
I was seeing 31% battery drain from Cell Services. When heavily using other apps.
Much much better now.
My problem stared when ATT pushed the WiFi calling update Aug. q, 2016

Can't believe this is the only recent posting about this problem. I have a Galaxy 5 and since the last update, the Cell Standby problem has made my phone practically useless. I read older posts about this problem, and this previous post solved it. I called AT&T and asked about it, but they had no clue. Thanks for the tip...it worked. Cell Standby doesn't even appear on the battery page after having the phone on for 6 hours.
I was having the same issue. When AT&T had that Wi-Fi calling update, my battery was pretty much draining form then on. SMH, they better fix this issue.
Hi all,
I tried all the possible solutions Greenify, Format etc. but my battery still drains more than 3% per hour.
Should I go and change the device from service center? I am wondering they will not take this as a replacement.
Do you disable GPS, Bluetooth and Wi-Fi when not using?
The standby drain will persist depending on the 4G signal strength. If you are in a strong coverage area, it should not be more than 1.5%-2%/hr. Also are you on WQHD or FHD? Disabling AOD and being on FHD helps.
Also seeing strong standby drain after the last update, not sure why?

Download 'Network Cell Info" from playstore and check your signal strength. (https://play.google.com/store/apps/details?id=com.wilysis.cellinfo&hl=en). Also here is a ready reference to evaluate 4G LTE signal parameters: http://blog.industrialnetworking.com/2014/04/making-sense-of-signal-strengthsignal.html
Hope this helps!

This. For some reason, the signal at my house is just horrible. Maybe it has to do with the tall trees surrounding the area? I get much worst standby time compare to when I'm at my vacation home.
Yeah this is only the negative I have right now with this phone. I get impressive 6 to 7 hours SOTs before needing recharge but standby times are bad despite no using AOD and keeping all apps at always sleep in settings but I am not rooted yet.
My rooted S5 LTE-A with RR gets impressive 2 and sometimes up to 3 days standby with 3G/LTE but thats with greenify and adaway.
Anyone here with rooted S8 with greenify get more standby time?

How do you get 6-7 hrs SOT when your standby is bad?. My standby is about 2%/hr and I get 4-5 hrs SOT mixed wifi and 4G LTE.

That scenario would be charging the phone to 100%, LTE/3G at full bars, watching youtube podcast videos @ 480p for total of 4+ hours, reading ebook for an hour and some web browsing for remaining time till 5%.
Problem is when I charge 100% and just leave the phone for about 6 hours no use whatsoever, i get 85 - 80 after checking again. That is with good signal as well.

The SOT needs to be ignored. What matters is standby time. If we dont use the phone for a couple of hours and you see the battery drop considerably then something is wrong with your apps/signal. BBS/GSM helps point out the wakelocks for apps, but a bad signal has limited options. Its high time, Google & OEMs should try and address the standby drain issues. This is one area where iOS excels, due to a closed and nuclear approach towards apps.
