We always neglect the way we charge our mobiles, it’s very important to equally take care of your phone’s battery along with your phone. So, when it comes to the charging then you will have to ensure that you never overcharge your phone which means that never put your phone for charging over night as this may hamper the battery’s life very badly due to which you may even end up spoiling battery sooner than expected. It hardly takes 3 hours for phone to fully charge, so never charge your phone more than this time.
Also, many of the users tend to charge their phones regularly, like even if battery goes below 50-40% people tend to haste and put the phone up for charging. So unless and until you are going away from the charging point, it’s not a wise decision to charge it way ahead than the battery zeroing point. Make use of the AC chargers rather than using the USB points for charging the phone as basically the USB charging does the trickle charging which is not good for often charging the phone.
All batteries has the Golden color notch pins and with frequent pull outs these notches become loosely fit and are rubbed with the pins which leads to the wear and tear of the contacts and hence it decreases the life of the battery and the effective charging of the device is not passed on to the phone as the contacts in the form of pins gets loosen up. And also last but not the least never make use of the batteries which are not as per the prescribed specification chart which comes along with the phone and always use original batteries which can be purchased from Samsung.
Never put additional sim cards or anything like that in the compartment of the battery as this may cause some serious issue with the battery and may even explode at an extreme situation as every battery generates heat and it requires space to dissipate that heat and if its interrupted then it can be dangerous for batteries.
Unless and until you are not using the actual 3G Service, it’s better to choose the GSM Mode network rather than selecting Dual mode or the WCDMA Mode which drains the battery faster than the GSM mode.
Make sure that you set the brightness of the device to automatic and not to the fullest which is set by default, since it’s a touch screen phone back light should be not more than 15 seconds as that’s more than enough which can be done by going to HOME > MENU > Settings > Display > Brightness and Screen timeout
Make sure that You Tube, music listening, programs which runs in the background including the Sync option along with Bluetooth should be turned off whenever necessary as these too constitutes fair amount of battery drain.
GPS as well as the Camera eats up a lot of battery, so always remember to switch these both off when not in use or necessary and specially when battery is low then it’s advised to not to use these features which can be quickly done by setting the widget shortcut on the home screen itself, touch and hold on the Home Screen in the blank area and not on any app icon and select Widget>Power Control. Add this Widget to your home screen to choose the express settings

OP,
WTF - you can't overcharge your battery. The ROM/kernel doesn't allow it. The closer the battery gets to 100% the voltage is decreased further and further. At 100% there is just a small trickle that roughly breaks even with the demand of the phone. Telling people they shouldn't leave their phone plugged in for more than 3 hours is ridiculous. There was just a thread on here a couple of weeks ago where an AT&T employee told someone the same thing, and everyone was making fun of how stupid that advice was.
^+1 !!!!!!!!!!!!!!!!
Sorry, OP. You are passing off bad information.
Thread closed.
Hey guys, I know hussainmicromaxa60 has recently posted a battery saving tip post, (copied from cnets post) but really what cnet said isnt of much use. i.e switching off GPS doesnt save battery as android only uses it when it needs to, the rest of the time its off anyway. So I thought I post a youtube video here with the tips I have found actually useful:
http://www.youtube.com/watch?v=sUAlbkvlVQ8&feature=youtu.be
The tips are to use programs like cpu spy and betterbatterystats, to find and stop partial wakelocks,
switch to 2g when you are near wifi
Use an app like screen filter when indoors or and at night
And finally check sync intervals for apps and change them to a longer time period.
Let me know what you guys things of the video.
best battery life
I have read the new forums that wipe battery stats would extend battery life. I have tried that repeatedly yet I'm not so sure that he does. The jury is still out on this. Perhaps someone that knows better can advice.
I have also read in some forum and I think this comes from T-Mobile, that wiping battery stats does not actually extend battery life.
The only certain thing is that if you want better battery life you must buy a better/bigger battery.
Well, I'm sure some applications can really help your battery (Juice Defender, Green Energy, etc..), however, I gave up all that and I'm using common sense (not a market app).
So, only use wifi when needed, wifi drains battery really fast. Same goes for the use of 3g. Sometimes it's like a taximeter when you turn it on.
Brightness, it does spend battery, keep your screen confortably visible but not on max brightness. Don't know how far "self adjust" works for everyone, but CM7 allows you to personalize the self ajudsting methoods more to your needs.
Voice calls don't spend much battery, what does spend is apps, games (specially the ones with nice graphics and stuff), network, and so on.
I don't listen to music on my phone so... I'm not sure how much battery it takes to use it as a mp3 player, however I have an iPod for that, so I avoid listen to mp3 on my phone.
GPS... hardly use it... only when needed.
So, for all the "extras", only when needed seems to to do the job.
Also, disable "vibrate" when you don't need to. Like, cm7 vibrates on some awkward ocasions, like when you pick up a call, hang up, etc... if you don't need it, disable.
It's really personalizing your rom options to the point where you don't need additional features just for the sake of having them turned on.
Use your phone and features on a "when needed" basis and your battery life will be be longer.
Also, widgets, they do use battery, and sometimes, more than needed. The ones that use Internet (wifi or 3g) use more battery. Facebook, twitter, etc...
One more thing, about the CPU governors this time. I usually keep mine on a on-demand. When it runs low (under 20%), it switches to "conservative". It does get sluggish, but you get a few extra hours out of it. It's usefull for emergency voice calls.
Try to "underclock it" when not using (screen off, charging, etc..) and use overclock if you're really sure you need to. Most of the times the max allowed cpu without overclocking is more than enough, unless you're a performance maniac and need the best of the best performance out of it, there's really no need to overclock it.
If you play a lot with your phone (like me), at least keep a usb cable or a charger with you.
Hope it helps
PS - Some apps allows you to customize the way your phone spends battery. I find Juice Defender really cool for that. Spend about 20 minutes tweaking it for your needs, and the next couple of days with final adjustments and you'll notice improvements.
nice

wiping battery stats will not improve battery life.
screen brightness is the major reason for battery drain. so keep the brightness as low as possible

Things like juice defender ect can be helpful i guess but i have never seen much of an improvement, in terms of wiping battery stats, all it really does it to allow android to read with better accuracy the amount of juice you have left, so it does not increase battery life at all.
Things like cpu governers etc is quite advanced, and I dont know really much about it, but as long as you keep under control misbehaving apps, switch to 2G when needed and dont have apps checking every 15 minutes for new data, you can get through a full day, no problems.
Also, keeping your battery in good condition always helps. First few charges, charge overnight, first week or two never let it go below 50% charge, and keep total discharges to an absolute minimum, and you should have a battery that wont degrade too quickly.
No matter which phone you have, an iPhone or a GS3/GS2 or a Xperia device, you always fret over the battery life of your device! (Xperia owners a little more)
Instead of splashing out on expensive battery packs, here is a list of things you can do to get the maximum out of your battery :
1. It’s all about the Apps!
Many of the more than one million apps available to download to smartphones contain programming errors and software bugs that mishandle power control. This means your devices can remain active when they should be sleeping which further leads to unnecessary draining of your battery. Identify these apps! (Other apps like Carat can help you with that) and monitor there use!
Also, there is a good chance that there are apps running in the background of your phone that you think you closed or reappear each time you reboot your device. Fortunately, it’s easy to identify and correct this on the iOS and Android operating systems with a few easy steps. All open apps drain battery, so in this case, the lesser, the merrier!
2. The battery is always better on the cooler side!
Your smartphone most likely uses a Lithium Ion (Li-ion) battery. Be aware that extreme temperatures can negatively impact battery life so whenever possible keep your device in elements between 32 and 95 degrees Fahrenheit. While a frigid phone should reclaim its functionality once it returns to room temperature, an overheated device could permanently ruin your battery. Over the course of a year, prolonged exposure to climates above 95 degrees could reduce a phone capacity by as much as 35 percent.
Remove any protective cover or accessory every time your phone is being charged. When you’re walking around, keep your phone in a ventilated holster or belt clip rather than a sweaty hand or pocket. Over-charging will also contribute to an overheated phone.
3. Always look at the bright side of life! – well the screen actually!
Turn on Auto Brightness! Most phones have an ambient light sensor that adjusts the brightness of the screen based on the light around it (darker in dark places, brighter when there’s more ambient light) to both save battery and make it easier to see. Turn Auto-Brightness on and you’ll save battery because your screen will need to use less power in dark places.
If not, manually adjust your screen brightness according to your needs by accessing it from the settings menu.
4. Stay (dis)connected!
Transmitting data wirelessly takes battery and leaving Bluetooth on to accept incoming data at all times requires even more juice. Turn off Bluetooth except when you’re using it (duh!) to squeeze more juice from your battery.
3G can be a real battery zapper, especially if you’re using it in an area of marginal coverage. If in doubt, your phone probably has a toggle setting where you can set your phone to use only 2G, You will soon see an extension to battery life that way while not really compromising speed or service.
And disabling a 3G connection when not needed is just the start. If you know you’re going to be away from home or a known wireless Internet connection, turn off your Wi-Fi locator. Also, GPS is particularly handy if you find yourself navigating somewhere new, but don’t leave it on all the time if you’re not using it.
5. Zip it!
When in a meeting or a movie, switch your phone into silent mode. Unnecessary notifications will only lead to lesser battery life. Use a basic ringtone! Advanced ringtones can sound better, but the phone will die soon! Also, turning off location services and push-notifications is definitively a step-forward towards saving battery life!
If you discover your smartphone seems to be running out of battery life quicker than ever despite your habits remaining unchanged, it could be worth investing in a spare or new battery. It’s worth noting that aftermarket batteries not made by the original equipment manufacturers (OEMs) are considerably cheaper. They do, however, vary in quality. Some aftermarket batteries can be trusted, but be aware of ‘too good to be true’ prices for smartphone batteries on retailers like eBay. You could end up with junk, or worse, a faulty battery that permanently damage your device. Buy carefully and smartly from trusted retailers to be safe.
Underclock your phone to 800/1000Mhz (while you are travelling) cz SGSII can do most of the stuffs within that speed.
Use Custom kernel like siyah wch has better battery backup than stock
dont set min freq to 100MHz cz 200MHz is much more energy efficient than 100 & has more operationg power !!
Come on man, show some love for Celsius! Besides, it is what most of the world uses and is not seemingly arbitrary (or based on how cold it gets in the average american's basement)!
Anyway, well written guide, may prove useful for the lesser knowledgeable folks out there
Whilst I applaud you for putting this info together, it is not specific to the SGS2. This is SGS2 General. This kind of thread belongs General Discussion or at the very least in Android General (tho probably the former).
For 1. I would recommend using an app such as Go Power Master, as it tracks which apps are running as how much power they are using. Some apps are always running, but use very little power while others can use a lot while it is running.
Also, if this may be applicable:
If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors (as mentioned above), and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on. As far as power cycling, I run my Atrix 2 in performance mode all the time, and with a CPU overclock of 1.25GHz and various tweaks, I have about a day an a half to a day and a quarter of full runtime from my battery. This is moderate to heavy usage (calls, emailing, text, gaming, web browsing, etc.) so you should have no problems getting acceptable battery performance after following these steps:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

Actually I underclock my GS2 to 800Mhz thanks to an AOKP Rom and my battery last one hour or one hour and a half more, which is great when you just have 7/8 hours of battery life normally. It didn't really affect the use of common apps, but of course if you want to play big 3D games, I suggest you to clock it a its original rate (1.2Ghz for the GS2 for example).

This is bump charging and while it does work, it is not good for Li-on batteries. I'll find the link and edit it back in but bump charging will shorten the life of your battery due to inconsistent charge cycles.

Batter Calibrator –

**Note that this can be done two other ways. You can boot into CWR or Custom Recovery and go to Advanced Settings and there will be the Wipe Batterystats.bin option. Or you can do it manually by going into /data/system/ and deleting the batterystats.bin in there. Any of the three methods work to get the entirely same result in the end. I just like using the app or manually myself. **
<Snip>
Recently there has been information debunking this process. I will post it below, however I know what it says, but I also know what I've seen/experienced too. Here is the post by Dianne Hackborn, a Google Dev on her G+ account.
Dianne Hackborn - Jan 12, 2012 - Public
Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

The point of doing so is if you happen to get incorrect battery reporting, which DOES occur in certain capacities. So, in my book as well as many others, it does matter for these situations. If only one developer told you the world was flat, would you believe that also?

Battery stats has nothing to do with battery reporting. And it was an engineer from Google's Android team that debunked the battery stats wives' tale.
So yeah, folks probably should believe a recognized subject matter expert when they clearly and concisely debunk misinformation such as the advice to wipe battery stats.
Also, it bears mentioning that the os clears battery stats upon every reboot, making the advice to do so even more pointless than it already is.

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.

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.

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).
Hello everyone,
So I've noticed some people have been complaining about the battery life on their phones, I've gone through the same woes and complaints with every Android phone I've ever owned. Here's what I do do get a much improved battery life... Some of this is non specific so you might need to find out if your version supports these features. None of this requires root access.
#1 First thing I do with any new phone is catch all the updates, not through the Android OTA feature, but I'll run it through whatever recovery software that the manufacturer has available to get it up to speed with the most recent version.
#2 After the update I'll carefully charge it to 100%. By carefully I mean not leave it on the charger overnight or for more than a couple hours after it hits 100%. Don't let the charge drop below 20% and don't charge it beyond 80% for a few days unless your device has a smart charging feature like ours does. The system is learning out habits.
Also, be sure to use the charger it comes with. Anything else might charge it in Turbo Mode and while our devices and batteries support this feature, be mindful of your use. It could possibly cause the battery to loose capacity more quickly over time.
#3 Keep Bluetooth and Wifi off if you aren't using them or you don't live somewhere where you're able to grab hotspots on the go (Comcast, Xfinity, these have so many hotspots in some big cities -Chicago does - it might make sense to leave them on here to save on data. Make sure if you're using Xfinity that you research creating a hotspot profile so your phone can do it automatically - there's an Xfinity app for that)
#4 Our phones also have an option for "extra dim" screens. This finesses the brightness just enough and should save power too. Please be mindful of your eyesight though.
#5 Heavy users - gamers, having Facebook polling for updates, and other programs can be working hard in the background. After a few days to a week, I'd check your battery stats and see what's eating up the charge and potentially limiting those apps or install the "lite" versions.
#6 Less nervous fiddling with the phone. I'm one of those people who have their phones in hand all day long. I started putting it down when I wasn't actually using it, and keeping it in pocket or elsewhere. Too much playing with the keys I noticed I was constantly turning the screen on and off. That will definitely use up a little more charge. Don't worry, your phone won't miss you! It's ok to not pay attention to it when it's not in use. It'll let you know when you have a text, call or whatever if you turn the volume up
That's about all I do on my phone and I easily get a full day if not more (unless I'm excessively playing a game all day). This has been true for me on any Android phone I've owned across the board since using this approach.
