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).

Yes I think so because this is just statistics, it will not affect the actual battery life of the phone.

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.

This is from my battery guide. OP (or anyone for that matter), feel free to check it out. There is far more information, apps, deep memory management trick,... Link is in my signature.
Batter Calibrator –
<Snip>
**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.

I have been humming along on the P900 with the HyperDrive rom which just seems to work flawlessly and give good battery. Reading many posts that talk about battery life decrease on lollipop for not many more functions. I want a touchwiz rom because of the multiwindow functionality.
Does anyone have any comparison comments between a solid kitkat rom on P900 (like HyperDrive) to LL on the P900 (like civato ROM)?
Trying to decide if it is worth the investment to change it out and test etc. Thank you.
To be honest with you I was chomping at the bit for lollipop on the Note 4 due to the additional multiwindow feature of having the ability to swipe in from the upper corners to convert a fullscreen app into a windowed one. That function alone was enough for me to switch.
I've been on Civato's lollipop ROM basically since it came out and the experience is solid. I have no battery life complaints - to me battery life is less ROM dependent and more user software/use dependent. Everyone's mileage varies based upon load placed upon the device so manage your apps and you will be fine. For me i use Xposed module Amplify to control a handful of wakelocks and alarms to reduce standby drain, I also use Greenify to hibernate apps (and have ALL of the xposed based greenify features turned on). That combination gets me great standby drain of under 1% per hour (well under at times). Currently my battery is at 85% having been unplugged for 9 hours and having an hour of youtube streaming on it.
I'm not sure what features one may be fearful of losing on the move to LP but i don't think battery life should be a major concern but that's just me.
this tab should never lose 1% per hour idle. ever ever ever lol
it has a pretty large capacity, 9800 mAh, and is not cellular. I don't run any kind of hibernation or kill mods, and can go almost all day idle per 1%
I am using Hyperdrive, and my friend also has the p900 -- his on civato LP. same result
I do wish I had that multi window minimize option, but I like the stability, smaller resource footprint, and mod compatibility of KK. I use/do a lot of things that most other ppl who mod probably wouldn't though.
also the full screen Recents screen on LP would bother the hell out of me lol anything that goes full screen disconnects me from a couple games I play (as if I received a call or something). on KK with partial screen Recents, I can kill apps anywhere any time without having to minimize or close the current app(s)

Never say never. Depends upon what software people put on their devices that may produce wakelocks or frequently wake the device. Things like weather apps, multiple social media apps at once, multiple email accounts with lots of incoming email via push etc. I mean I totally agree with you, these tablets have a great kernel and sip power well at idle but OP brought up battery life as a concern over switching so I addressed that and arbitrarily tossed out a number and qualified it with a well under remark to boot. The typical reality for me is when I set my tablet down in the morning at work and pick it up 4 or 5 hours later the battery percentage hasn't changed more than a percentage point.

i don't use social media apps but my friend does. neither of us kept the email apps -- uninstalled from /system
I have like 20 push-notification enabled games and other background services including weather. he probably has about 50 or so push notification games. he's always struggling to find room to keep games installed lol point being we both have what would and should be perceived as monstrous wakelock
issues, but in spite of that still get great sleep times
idk how much we can credit the kernel for the long sleeps to be honest. I know kernels have a large impact on it but I've owned 7 android devices for 2+ years and all rooted within hours out-of-the-box
this one is a survivor, above all expectations I feel that the battery capacity is the largest factor here, because, for example, 10 wakes in an hour on a phone and 10 wakes on a tab, both with tuned custom kernels, should drain almost exactly the same power as each other. only with very minor differences
but that amount of power, is a smaller portion of the larger battery that was necessary for the giant screen. see what I'm getting at?

Definitely do yes and agree, the high capacity of the battery compared to other devices makes a huge difference in observed standby drain. I'm just not as comfortable as you are in speaking in absolutes, these subforums have far less battery related posts for a reason and that's the main one.

Are there people out there who mostly use their OnePlus 6 with WiFi yet your phone is mostly idle?
What's your average WiFi battery drain? Could you please upload your main GSam Battery Monitor Screen?
My phone is connected to a WiFi router (2.4GHz 802.11n) and the signal strength is excellent. On average my OnePlus has a 10 mAh discharge rate which is several times higher than for my old Nexus which is connected to the same WiFi network.
Here's my data:
20% of 50% of battery used for 31.5 hours.
3300/31.5*0.2*0.5 = 10.48 mAh.
No one uses OnePlus 6?
Actually, people don't left their phone in the corner for days, so you know, you never know.

I use a PC up to 16 hours a day. Not everyone is obsessed with Instagramming or twitterring. I only use my smart phone when I'm en route and I occasionally use instant messengers.
Those who've replied < 6mAh, could you show your GSam screenshots, please?
What type of WiFi router do you use? What WiFi standard? Do you have MiMo enabled on it?
If you rock your phone with that minimal usage, I recommend using ElementalX kernel and LKT magisk modue with battery profile, I'm getting way more battery with this setup compare to stock one (about 4 more sot). But you'll get 30% more lagginess

I wonder how a custom kernel might help with the WiFi module battery drain. I barely receive any notifications and according to GSam my phone is in deep sleep mode most of the time. There's something else wrong but I've no idea what exactly.

Cause no one use their phone like you do, and it's pointless to measure your phone for fun.
BTW, as you describe, you may encountering oneplus most famous problem, "super deepsleep". You might wanna turn off battery optimization of your apps which send notification and turn off all advance battery optimization (deep optimization, sleep standby optimization).

Battery Optimization: Not Optimized Apps: None
Advanced Optimization: Deep Optimization/Sleep Standby Optimization: both OFF (I don't want to enable these two because I'm afraid I will start missing notifications from apps).
Am I missing something?
Edit: what's specially funny is that the guy who posted OnePlus 6 battery optimization guide has the same issue though he doesn't admit it. If you take a look at the screenshots he posted, you'll immediately notice that his WiFi usage is the second worst battery offender after the screen.
I still wonder why almost no one cares.

Hi everyone!!
I'd like to get some advice about my issue that I've been having for a while...
My battery drain is what you may see in my attachments. Please tell me some good advice to reduce this drain or whether it is normal functioning either...
In conclusion, I'd like to know if it might be convenient to replace the battery and, furthermore, whether there are larger batteries with more autonomy.
My phone is 2 years and half old but to be honest I use it intensively with its battery-case (manufacturer: Newdery).
Thanks!!!
Sorry for late reply, just saw this.
You get 6 hours of battery life with 14% screen on time? That doesn't sound to correct.
My suggestion would be to install the app: AccuBattery. I swear by it - it is very good I think. It will watch your apps much better than the stock android battery monitor. It will also tell you your battery health, the mAh left out of the total of 4000. If you have a very low amount left (capacity wise) then you may want to get a new battery. But make sure to do several charges before taking it as accurate. Use the app for several days, even the little "notes" in the app will tell you this - it's to "acclimate" to your use and give you more accurate statistics.
Hopefully this helps - 6 hours is definitely not good.

Hi!!
Thank you very much for your reply!
I forgot it but I already had Accubattery installed on my phone.
In fact, in attachment you have the battery wear data from April 2021 till now..
I hope that I shared you useful data to analyse the issue.
What do you think? What should I take from the app?
I thought that the new Android version 11 is the cause of battery drain as another phone (Xiaomi Redmi Note 10) suffers from it after the upgrade to Android 11..

No prob
Could you take an [extended/full] screenshot of the "Discharge" tab? That will show more info about which app is draining more. Also those numbers change I believe on every charge so you'd have to just keep an eye on which app is always at the top of the section under "Foreground App Battery Usage > Battery Usage" section. Hopefully it isn't just "system" or something, hopefully it is an app that you can remove/freeze.
And what does it say for Battery Capacity above the "Battery Wear" chart?
And speaking of the wear chart, you'll want to stop charging all the way to 100%, it looks like you're putting over 1 cycle of wear on the battery very often which will degrade the battery quicker. The 'Charging" tab explains this even allowing you to set a reminder to unplug at a certain charge level (it tells you the higher you charge the more wear you put on the battery - unfortunately that's how batteries work).

Hi, thank you for your reply!!
I'm sorry for my late replies..
In the attachments you have what you asked me.
It seems that Facebook drains the battery a lot despite the fact that I don't use it much.
The battery wear seems to be almost one fifth of total capacity for a capacity of about 3200mhA.
I'd like to have something better...
I have set at 83% the alert to reduce the wear of the battery but I wonder how it could work fine when the phone is turned off..
No problem
So, I'm not exactly sure how you use your phone but it looks like the screen-on at 23%/hr looks pretty bad but then also it says combined time was 102 hours? I believe that means how long it's been off the charger. If that's the case you can't get any better battery life than that, that is really really good.
You mention facebook doing a lot of draining. Try researching a good app freezing option on the app store. I only did a quick search but this one came up: https://play.google.com/store/apps/details?id=com.catchingnow.icebox but read the reviews (I did a quick scan and it looks like it might work as intended) and look around maybe there is a better one. But the point of this is, to freeze any apps in that list (the accubattery foreground apps) you barely use and it will prevent them from running in the background. This will definitely give you better battery life.
And I don't see the deep sleep statistic, is that around 90hrs along with the screen off time? It should be more than the screen off time at least, because if it is then it is deep sleeping correctly (no rouge apps causing it to not deep sleep), but if it's less than the screen off time, then something (maybe facebook) is keeping the phone awake even with the screen off, causing extra battery drain.
And 83% charge is pretty good, maybe even 75% might be better, I think from 0 to 75 it's like .3 or .4 wear but it's like with these batteries once you start going over 75% it jumps in wear dramatically. And if the phone is off (turned off completely you mean?) then the battery won't gain any wear because it won't be in use at all.

I noticed that I didn't make all the screenshots, but now I've just done them with regards to this new discharge cycle and you have the deep sleep statistics for a better analysis - they are in attachments.
I asked here for a longer battery lasting and instead I set it as 75% as the maximum percentage value of charge that reduces my autonomy but saves the battery.
However, yesterday I noticed that the charging wasn't deactivated when the phone reached 80% of charge (is the value that was set yesterday). Oughtn't Accubattery deactivate the charging?
The statistics you mentioned in your previous post appear to me a bit awkward even though they are related to many sessions in the last 7 days.
I use my phone with my phone case-battery (Newdery manufacturer) and until few months ago it could charge the phone up to about 80 % when I couldn't charge my phone through its charger. I need the charge to last a day, almost 20 hrs…
I noticed that the phone started to wear - the last few months - when I noticed that I couldn't have the phone working till the late evening and I tried to charge it fully before I left my house...
However, it is clear what I need for my use and habits, thus, new reliable battery-case suggestions would be a good hint for me...
In the end, I don't know what to do about apps that manage the apps freezing because I don't know how Android allows it and if it is worth it..
Hello.
I installed Accubattery some days ago to check my S22 Ultra (snapdragon) performance.
Since a few updates ago, It is not even reaching 5h SOT with 22h total combined use.
Everything on my phone is stock. Nothing done about "optimiziation". It doesn't make any sense to buy a flagship and use it as an entry-level phone.
My settings are:
- Mostly on Wifi
- FHD+ with 50% brightness and adaptve refresh rate
- No bluetooth or NFC
- No AOD
- Most notifications allowed
- No battery saving mode
Mostly use it for browing, social media and youtube.
Camera app is a battery draining beast when used.
To my surprise, the app shows my phone is around 4400mA of battery, and discharging performance is as follows. Has anyone ever used it?
All Samsung's should be optimized. 50% brightness is too high for indoor use; use manual brightness control and stay in the 30-40% range when possible. Cloud crap uses a lot of power in the background, Google backup Transport is a prime offender. 4G is more efficient for light bandwidth; make sure it's using 5G only for large data transfer bursts. If the download site is throttling data than 5G burning battery for nothing.
With 4400 mAh my N10+'s easily get 13 hours... and in actual usage they're only a fraction of second slower for most tasks.
I'm not pleased with Samsung today. No expandable storage makes you depended on cloud and/or external storage. A profound loss of balance and core functionality because of poor design. In part because Google scoped storage. I run on Pie and Q still. No 5G, variable refresh rate and the camera is less processor intensive.
That doesn't mean though that you can't improve your SOT dramatically.
This N10+ N975U/Pie I'm holding use to be a hot running hog, it's SOT was similar to yours... it sucked.
This is what it's doing today on a appropriately 3400 mAh derated battery that's nearing the end of its service life. A completely different animal and all modifications were done with a stock platform.
Until you put some serious effort into optimizing it you'll never know what it's full potential is...
You've only use the app for 7 charges. It's not enough data. Come back in a month to see where your battery health stands !

The Google Android bucket concept is a mess. Leave it on for 2 months and it still sucks. The results will be vastly inferior to one that was hand optimized. Google Android isn't that smart.
Manipulate the bucket states as much you like and on a fast phone you'll notice nothing. I played with it for months. It may work on Pixels but Samsung's are a much different animal.
If you actually tone down a hog you'll notice it within a day or less. Its going to take more insight than just flipping on global power management though.
I also have a SD s22 ultra (908e). I was getting terrible battery life. Get adb control app for PC and debloat everything you don't use ( i used uninstall option) I went from a shocking 4.5-5.5 hours sot to a consistent everyday 8-9hrs sot also make sure you put all apps that you don't need notifications instantly for in deep sleep manually.

In individual app settings disabling background data and battery activity doesn't invoke global power management.
Close out apps when done with them as some apps like Brave will continue to run in the background and can use a considerable amount of battery over the course of a day. Camera is another one to watch.
Use Device Care>storage>clean now as needed. The older 360 degree version worked better but should be firewall blocked if used.
Clear system cache; in general reboots do nothing that can't be done with the system booted other than the former. Needless reboots waste power.

Hey mate, may I ask which apps did you uninstall with ADB? I am worried to do stuff by my own because I'm not that knowledgeable when it comes to this stuff, and I don't wanna end up with a brick instead of a smartphone. I would be really grateful if you would respond Thanks!
Also, it looks like you only had 7 sessions of charge and that too the phone wasn't charged to 100%. Charge it to 100% a few times and you will get a better estimate of your battery health. 4400mah seems too low.
Maybe 6ish hours on 5g with WQHD and Adaptive motion really aint that bad.
Why does accbattery estimate the battery size at 4885. Thought s22u had 5000mah battery?

By usage. You can manually set it to 5002 mAh if you want. How accurate the absolute estimates are is unknown. However serve over time as a reference point.
