Solution: 2nd post!

I DID IT !
almost in the same time it drained almost all the battery before, now it has lost only 1% or 2%!!!!
after reading every single post on the internet (many thanks to who has investigated battery drainage), i've mixed the tips and tricks and what i did is:
(Maybe a lot of things are unnecesary)
- Disable syncing in gmail account (everything)
- delete software update's cache
- killed all services except only 2 first party services: SNS and Google services
- Tweaked the apps running on startup with "Autostarts" app.
- 3g off
- Wifi off
- BT off
and, as you can see, it's completely idle. it stayed like two hours without losing battery, constantly at 71%.
I hope this is helpful! I will try to discover slowly which one of these things drains so much battery!

it looks to me that to solve your problem you transformed your phone into a nokia 6310.
It was a good phone, lasting days or weeks but it had no 3G, no wifi, no mail sync ... just like your phone now
What happens if you turn on the 3G and the Wifi ? DOes it drain the battery in couple of hours ?

Just by turning 3g off will help
looking at the graph you posted it looks like where it has poor signal is when you experience steep drainage.
good idea to have all the features turned off when you are not using it. especialy 3g cause it will keep draining to get a better signal.
try using one of those widgets to turn on and off 3g so you don't have to drill into settings every time you need it.

You only have to keep pressed the power button and select the second option to disablr 3g... Data network.
I will update soon!

Check Android OS and System use
What is the Android OS and Android System use?

i'm on debusrom, gingerbread 2.3, in spain.

your problem is probably only solved temporally, all method you said has already been proven not working. it's probably a serious driver issue in all exiting gingerbread roms for sgs, have a look at this: http://forum.xda-developers.com/showthread.php?t=1039696

My new broadcom wifi driver works like before update, phone is not sleeping ! It is not a wifi bug, it is not a dirty ROM flashing, it is not random app. Only 2 things left to consider Gingerbread core fault or broken device driver other than modem, wifi...

What battery status app is that you're using?

i am having batt drainage too...but is on MIUI rom...I am not sure why...my initial guess is kernel prob....still investigating it now~~~

So, why you post it in here if you are on MiUi ??

that means turning your SGS into a regular Nokia 1100. Why disable all features that make your device a smartphone?

i have used many stock and custom rom results are similar
disabling background data and syncronising gives better battery usage but makes it a simple phone

I'm shocked that turning off all that improved battery.

Connection Drops in apps full connection bar

I am on 3g HSPda network, whenever I move from one place to another in car, I lose connectivity, the arrows beside H symbol in notification bar, gets fixed .. I cannot browse anything at that time. Sometimes this gets fixed by switching to airplane mode and then back on, sometimes I have to reboot. Data remains always stable if I stay at the same place. Also this doesn't happen always, but many times while I'm on the move.
Is this a normal problem with PPP/this rom, or am I the only one suffering from this issue (some rogue applications or something)?
Also, do anybody of you has some solution to minimize or solve this issue. Or any other ideas?
Note: I am using pongster's Hyperdroid CM7 ROM with seadersn's r9 kernel & I have CLK.

Here's how I get stuck, I'm really looking for a solution guys, please help

Try the *#*#4636#*#* under normal phone dialer. Go to phone information, look for data connectivity, change wcdma preferred to GSM auto prl. Reboot and see if that helps with clk related disconnects.
Or go to magldr version, much more stable on data for most.

Thanks for the answer scariola.
GSM auto prl will be Edge only, I will like to use 3G/Hspda ( I'm paying higher price for it )
Feeling sad if I have to switch to Magldr, I like few of clk's features .. charging while off, ROM Manager support etc.

I could swear that you will still get 3g connection, have even switched my own phone and great 3g signal.
You can always changed it back to wcdma preferred, I thought it worked better for reconnecting automatically on clk.
Magldr is pretty nice, switched back awhile ago, since I use wifi calling, its my only option.

have you tried flashing tytung's gps fix? also if you look at my threads,there's a detailed description of what to do if your not a fan of flashing lol cos im quickly realising alot of people do not like flashing or they do it wrong(NOT SUGGESTING U R 1)

+1. I too have the same problem. Tried *#*#4636#*##* doesn't seem to help. I was working very well until 3 days before. Suddenly there is no H.. Only 3H and E.. :-(

Looks like you missed this thread.

[Q] Standby time. Wifi vs 3G, why 3G is better?

This problem has been bugging me for a long time.
One of the battery saving tips is to always use wifi whenever possible because the 3G antenna uses more power than the wifi ones.
http://forum.xda-developers.com/showthread.php?t=1630947
http://www.speedguide.net/faq/2g-vs-3g-vs-wi-fi-battery-usage-on-mobile-phones-362
but my real world experience is different.
standby time is awesome on 3g and abysmal on wifi.
below is data comparing wifi and 3g.
wifi loses 10% while 3g loses 2% over 6+ hours
(refer 1st image below)
Initially i thought that 3g is more efficient because i disable background data for many apps on 3g.
In the data usage monitor, i mark my home wifi as a hotspot, so it will be treated as 3g and background data will be restricted as well.
but look at screenshot below. nothing's change and power lost is still 10% over night.
(refer 2nd image below)
What i really want to know, is this normal for other phones as well to have better 3g standby time?
anyway to improve wifi standby time?
please let me know your thoughts

It depends on many factors:
- The power level of the transmitter (3g/wifi)
- The distance from your phone to the transmitter
- The settings in your phone (e.g Keep Wi-Fi on during sleep, ...)
- The data volume is actually sent/received during that time
- . . .

I tried this in different house with different router.
The results are the same. Battery drops alot faster on Wifi then on 3g in standby.
I'm worried something is wrong with my wifi module.
Is this suppose to be normal? How is your battery standby time differs in Wifi n 3g?

Sorry, I personally don't use wifi so I don't know. My device is on 3G/H+ almost time.
One thing I forgot to tell you, it may be due to software issue (modem, or baseband).
Check if you have the latest Baseband installed?
(install Phone INFO ★Samsung★ app, look in the FIRMWARE INFO section).
You may need to update your Baseband, or flash another Baseband!

You can alo check baseband version from Settings - General - About device.
No need do install any "one-time-use" apps

Hi....... Almost how long does your phone battery last while continuously on 3G and screen on?

On wifi my battery life is almost doubled! You should see if there are some local network services running on your phone, something related to media servers or automatic updates of some applications via wifi only.

i figured out the reason. i turned off wifi power saving mode in *#0011#, once turn it on it's as good as 3g for standby time.

How did you change the wifi power saving mode in *#0011#?
Please step by step. Thanks.

OK I see. Mine was turned ON by default.
I don't know why this WiFi Information menu is available in ALL service menu's, e.g. *#2263#, *#1111#, *#2222#, *#0011# ...

[HOW-TO] Stop wifi from dropping

As many may have experienced, when connected to wifi after a few hours, WiFi stays on but disconnects from the access point for no reason. It seems to happen on the s6,s s5 and s4 on lollipop. Was I'm Howard forums and someone with an s4 posted something that may work.. Touchwiz has a wifi power safe option turned on. His will show how to turn it off.
Dial *#0011#
Then when the information screen shows up, hit "more" up top. Then hit wifi.
When the new screen comes up, just hit wifi powersave off to turn off the powersave feature. Haven't test for long. Let me know in the comments if it helps

Does nothing for me I'm afraid. Is this any different to the wifi setting "keep wifi on during sleep"?

Does also nothing for me...says wrong.. Mmh

Are you guys using the stock dialer?
I remember the code wasn't working with 3rd party dialer I was using before.

That is switch for the power save mode. It will disconnect wifi for a few seconds.
No noticable change for me, no bandwith or signal strenght increase on 5GHz

I see I'll try it the next few days and report back ☺

Haven't had the issue since. I'm not sure if it's a firmware thing but it should not turn off wifi. This is how is supposed to look

This setting destroyed my standby battery life.

It will disconnect wifi for a few seconds.

S6 Disconnect Problem
I had the same issue and solved it by changing my routers security from WPA2/Mixed Mode to WPA2 Personal. Since this change, it works fine on both 2.4 GHz and 5 GHz. Tried EVERYTHING else first

this is an extremely annoying bug....data usage has increased significantly because staying on wifi is such a pain, rather just use mobile data. i've heard about the security change, but that's something I can do at home, nothing I can do at work unless I somehow convince corporate IT to change their wireless settings? haha, fat chance.
i just want to know did the change the OP suggested actually work? No one has reported that it actually works other than that it killed their standby time. anyone?

Worked for me, fido galaxy s6 edge thanks

Axon 7 (Official ROM) known BUGS

I use phone (a2017g, V1.2.0B.09) 20 days.
I have noticed these bugs in ROM:
1) Mobile signal stops presenting in battery stats graph,
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
2) Dolby periodically change my castom profile to music or turn off,
3) Double tap is not reliable,
4) In camera app for front camera, beauty mod is default and can't change.
List of bugs are not significant.
what bugs did you notice?

Not necessarily bugs, but annoyances;
Bluetooth always off after restart
Bluetooth won't auto connect to paired device
Live Wallpaper changes back to default without setting change

I don't know what people do to their phones but mine doesn't suffer these bugs. Selfie mode works normally, Dolby seems to work ok but I actually switch it off mostly. Double tap is good, BT auto connect usually works, maybe sometimes problems with this are partly to do with the audio device? I usually don't want to wait for auto connect as I have a lot of paired devices and will just go in and do it manually but if I leave it, it will work.
If I had all these bugs, I would back up data and reset the phone.

Sometimes my battery graph/percentage freezes and does not go down with use. Happened to me twice in the 2 months plus I own it.
But the worst bug is this phone kills SD cards.

1. Yes, having this too. Imo a definite bug since B09. But then again not that important i guess
2. stays customed
3. very reliable
4. changeable

Ideally, reset should not be the first resort to a problem but the last resort. Imagine if my Windows PC requires a format every time there is a problem, I will get no work done.
Having said that, do you know if reset will solve the SD card killing problem that some of us have?

Of course this is what we ment by doing a clean install if problems don't go away or reoccur.
Btw, resetting my phone and doing a clean install costs me some minutes. A pc is quite something different
No, unfortunately I do not think resetting this phone will resolve the sd-killing issue.

For example I have 3 apps running. When I tap recent apps it shows those 3 apps then I tap "clear all" it says "apps were closed" and shows the amount of memory cleared when I tap recent apps again it shows all same those apps again!!??
Whenever I close them by X icon on top right then it works but "clear all" never works
Anyone same situation?
