Hi,
Things that improve battery life:
- Drain the battery COMPLETELY until the phones shuts off and recharge the battery with the phone turned off. Do this 3 times. Improves battery life extremely.
- Disable repplog.exe in the notification queue with the comment "system time changed" using memmaid or similar tool (don't do this when you sync with an Exchange server OTA)
- Use advance config and enable all the options under "energy"
These are the 3 things I found in the forum that really work for me

BeeJive IM is a seriously intensive IM product that drains my battery very very quickly. I would suggest using Palringo. www.palringo.com It's not as pretty as BeeJive but your battery life with signifigantly improve.
I would also try using different radio's. Radios can help you improve battery life / signal strenth, etc. Test out all of the Raphael radios and available and see which ones works best for you.

I have tested the theory with draining the battery 3 times to it's complete and utter demise before charging. I found that doing it once worked best for me. Since Lithium Ion batteries do not have memory such as Nickel Metal Hydrate. I have found however that if my battery is acting funny to fully let it die then charge it up completely that it will return to it's normal self.
I have done a lot reseach on Lithium Ion batteries and found it's best to keep your device charged as much as it can and not let me battery get below 30% or 20% at the most before re-charging it. When I do this I get the best battery life as possible and my battery seems to last a lot longer in regards to the longevity of the battery as a whole.

Tips for improving the battery life of your SGS2

Hi, folks
These are tips for improving the battery life of your SGS2 :
1.Set the wallpaper , with dark or black images
Use autobrightness or set the brightness to 10%
2.When you are not using data , please turn it off . Using 3G data will suck lots of juice !!
On the other hand Wifi doesn't suck so much juice
Now the next steps are the most important
3.Please do keep charging between very short intervals ,
Let the battery charge drop to 5-10% then charge till it reaches 100% , this will considerably , increase your battery life .
4.Do not let your phone keep charging even after it reaches 100%.
This will damage the battery .
Actually when your phone shows that it has been fully charged (100%),it has only been charged for 95% , so plug in for a few more minutes ,for some extra juice .
5.Do not install lots and lots of unused and useless apps ,as they will not only occupy memory , but will also suck the juice out of your phone !!
6.Delete unused widgets from home screen
7.Close unwanted apps running in the background.
Go to task manager and press the ,'clear memory' button frequently .
8.Do not use the charger of other mobile phones , even if they have the same pin ,as this will slowly damage the battery
9.Use only original Samsung battery made for your SGS2 , duplicate or other battery will not only be waste of money , but will also damage your phone !!
10.Sugesstion are welcome , you can posted it , so that i can add it !!
11.If you know a few extra tips , please post it or PM me
12.If you like this tread please rate it !!
13.Please press the thanks button , if you like this post and if i helped increase the battery life of your SGS2
These things helped me improve the battery life of my SGS2 ,I hope it also help you considerably increase the battery life of your SGS2 too
Cheers ,
You're in the wrong forum, we don't have the i9100
and half that info is wrong

How to fix Battery Drain on S7 Edge

REQUIRES ROOT
So some of the users of the S7 and S7 Edge are saying they are getting below 4 or 5 hours of SOT with normal use. Today, I have a solution that worked for me and I hope it will work for you. I only own a Exynos S7 and so I'm not sure if it will work for other devices. But do try it out if you are getting bad battery life.
Remember try this ONLY if you are getting bad battery life. If you are getting good (5 or 6+ SOT S7) battery life then you are okay.
First of all, I would assume you are using some kind of battery life saving app (because who doesn't want better battery life) like Naptime, Power nap, Amplify, Greenify, etc. Now just uninstall of all the Power saving apps. This may sound bad, but trust me.
Next, install a custom kernel. I would recommend Modified Stock kernel as it's not over clocked and Prometheus kernel as you can under volt the CPU. Do not over clock the CPU if you do not need to.
Lastly use the smart manager in the S7. Settings-> Battery->App Power Saving and select the apps to save battery.
Let the phone go through a few cycles before reporting back
Let me know if I helped you and a 'Thanks' would be appreciated.
I'm on S7
i´ll try some configs without change the kernel, because i want to use Samsung Pay, so I can´t play with knox haha
i just change on configs and put all my apps to save energy always, everyone was on automatic...
i´ll try to use with power save mode too, but i´m almost turning it off...it´s to noticeable the slowness...
let´s see if i can improve my batery life, i never can do even 4h off screen on -.-

Do not put all apps to save energy, you will have problems with notifications. Just the apps that you don't really use and some games not the important ones.
Also try this: http://forum.xda-developers.com/galaxy-s7/how-to/standby-drain-2-8-hours-wifi-bit-4g-t3416864
It does not require root.

Smartmanager drained battery

Hi. Just wanted to give you guys a heads-up. Smartmanager absolutely destroyed my battery life, it kept my s4 lollipop from going to sleep/ woke it up constantly, android system was always the biggest consumer in the battery stats. So I removed it and rebooted my s4 and now it uses battery like one percent in couple of hours when idling :good:
"Smart" Manager: software created by your "friends" at Cheetah Mobile. It's a stripped down version of CleanMaster, and you are wise to remove it from your device.

Battery Life Analysis

So I want to know if you all have similar experiences..
I have Galaxy S9+ 128 GB Exynos Version - ALL STOCK
The screen on continuous use battery consumption is very good... it drains 13.5-14.5% per hour at max with location, 4G on.... Which means it can get to around 7 Hrs of Screen-on time easily.... even more if we use low powered media apps like youtube, netflix etc....
However, the screen off battery drain is relatively high...
A standard day has around 10-12 hours of standby time when you are out and moving with 4G on all the time and 1-2 hours of music... and in that time the might drain up to 35%+.... Limiting the screen-on time to around 4:30 hours... The deep sleep percentage of the total screen off time is around 65% which is no so great....
This is without using Power saving modes...
So the battery life gets around 7/10 for me.... It is good enough and for 90% of the days it will last the full day.... just not as comfortably as I might have hoped..
On my Galaxy S6 I used apps like Forcedoze, turned off sync, location, 4G, haptic feedback, unused apps, and I could squeeze livable battery life out of it... I am sure that if I did the same with the S9 the phone would have 2 day battery life.... but the out of the box battery life of the phone is average...
So I recommend turning off 4G when not in use and use Power saving mode once you hit 35%.... this way you can easily get through the longest days on a single charge....
The phone needs improvement to its stand by time....

I think that a lot has been said about this topic, and in the end, the user is the only one to blame for the battery life, because there are a lot of things that can impact battery: location, apps, usage, signal, etc.
Is hard to do an objective and good analysis of battery life, because each user will put their own subjective thoughts. For me battery can be great, and for others can be awful.
Is true that 4G will consume more battery, but only if you are in an area when signal is weak, otherwise, in most cases it will have the same drain or even less, because with faster speed, the modem works less and the impact is less as well in battery.
Power saving mode is going to save you some juice in case you cap all the options to the minimum, but honestly, who wants to run an S9+ with an HD resolution?, and the brightness and CPU cap don't give you much more battery either, and I found it stops the sync of some apps, but not others.
I think that the only real way to improve your battery is to properly configure your device, set the proper permissions for every setting and app, and then use the "Energy Monitor" built in app to let which apps can be running in background and which don't. Doing this will improve battery by miles.

The whole thing has to be intuitive though... having to tweak 200 settings in the phone to get better experience is not part of the experience... experience is the stock default usage with some minimal tweaking... This is the reliable battery life I can get without breaking any service in the phone because I might have to analyze the effects of every option I change or turn off..

Is partially true what you say: if you get a Samsung, is because you know you will have all those options and most probably you will have to make the proper changes. We all know that Samsung phones usually offer ton of features and options, but if you don't configure them, probably they will mess a little the battery because most of them will come enabled and will have an impact in battery life.
On the other hand, if you want just the basics and a simple experience, you should stick with Android stock or closer.
Is like buying a Ferrari, but then complain about fuel consumption.

Battery Life 14 MP3 playback (AOD on): up to 58 hrs
MP3 playback (AOD off): up to 102 hrs
Video playback: up to 20 hrs
Talk time: up to 35 hrs
Internet use (Wi-Fi): up to 15 hrs
Internet use (3G): up to 13 hrs
Internet use (4G): up to 15 hrs

Here is the link: https://www.samsung.com/us/smartphones/galaxy-s9/specs/
Now with that said, I think Samsung puts an unrealistic expectation on the battery and continues to misinform users with fake data. They should be a bit more realistic, really, 20 hours of Video Playback? They forget to tell you that is more than likely at the lowest resolution, with the screen brightness turned all the way down, with the device in airplane mode.
I don't think this phone will get anywhere near those battery hours. I also think we should expect at least 1 full day of HEAVY use. This is a flagship phone.
Now... All said and done... I get decent battery life, I cant complain. However, I do think it should get better battery life. This cost as much as my Dell Gaming Laptop.

Just disable everything what you don't use and set up the battery monitor for your apps and you will be good.

Well, car manufacturers do the same when they advertised they cars to give 5L/100Km, but we all know that in order to achieve those, you should drive in very specific conditions. The same applies here as well.
And yes, I also have great battery life in my S9+ and I can't complain at all.

These numbers are lab tests under controlled conditions... by no way they represent real life usage...
My S9+ has had an appalling battery life and i have no clue what to do about it.
Apologies for the second post. It was done by mistake and now i can't remove it ...
What is really bad is the network reception.
Most time of the day I have bad or almost no coverage.
No matter what phone I had had they all had average battery life.
So for anyone who has bad battery life take a look at this.
But this is just one cause.
I've got my S9+ for about a week now. Snapdragon version with dual SIM.
So far I finding the battery life a little disappointing. Using betterbatterylife with the ADB commands I getting around 4,5 ~ 5 % / h of very light use (essentially stand by).
I've turned everything off, from Google Assistant to bixby to others Samsung services and still I think it's drainibg too fast.

Can't agree more. Samsung has been consistently misinformative about battery endurance data since the first gen Galaxy S I9000 . "S" series never had good batterylife anyways.(keeping sweet Exynos S7 Edge aside when new).
