I was thinking of starting a performance mode thread. To see different peoples results and thoughts on different power modes. I read some people post that they just use it in power/battery savings mode. Some keep it in normal all the time. Others in balanced mode. Would be good to see how these different modes perform in real life usage. From user perspective. How do the different modes perform for you? What have you noticed from switching between them?
I've noticed, so far, that In balanced mode, battery drains about 10% or a little less an hour. This is with nonstop use including gaming, watching vids, web surfing, etc. now in battery savings mode, it drains even less per hour. The UI still performs smoothly. Only main difference you immediately notice is that it drops the contrast ratio. So a soon a you press the battery savings tab, you will see it look like brightness went down a bit but it's actually the contrast ratio lowered. If you look closely, the display doesn't look a sharp as other 2modes. Display still looks good but not a sharp. I haven't ran normal mode long enough to see how it drains compared to others. One thing though, web surfing drains battery just as fast as gaming.
Plus I think the modes doesn't affect gaming or video playback performance. I read that somewhere, either anandtech or Engadget. When watching vids or playing games, it goes into normal mode. So those things won't be affected no matter what power mode you in, I think..lol not exactly sure. Any confirmation?
I always keep in normal mode and I am more than happy with battery and performance. today I watched hangover 2 in 720p so that's 2 hours of playback played probably an hour of riptide an hour of cordy about an hour of all other games combined surfed XDA using opera and had textab running got 7 or so hours of battery

I will try out normal mode more to see what kind of battery life I get. There was a brief period that I used it that it seemed to drain less than in balanced mode. I always put it on normal mode if I'm charging it up and using it at the same time. The prime charges up pretty fast also.
bump, so we can see what modes people running on, battery life on them, and performance observations.

yeah it does charge really fast that is one thing i love i keep it in power saving mode alot and barely notice any performance issues
I tried both balanced and power saving mode but can't see a difference. If anything I believe balanced gives better life but have not tested formality. What are you guys getting?. Over two days with using standby I'm averaging what seems to be 7 hours or so. 13-15% an hour. Seems low based on what Asus claimed and what I've read from you guys. Maybe its true newness with installing apps and using it heavily?? I do not believe battery conditioning will make up that big of difference.

its really dependent on what exactly you are doing while in each mode. like now for instance, I have 72% battery left on balanced mode. battery time shows 2 hrs and 54 mins. I've done basically nonstop web surfing here reading and posting in the forum. this goes with what I said before that it seems to drain 10% or a lil less per hr. I've achieved about the same even in normal mode. its weird cuz you'd think in normal mode it'll drain alot faster when I've noticed it only draining a little faster than balanced. like I said, I think no matter what mode you in, it really depends on exactly what you're doing and brightness level.
I have yet to really test battery/power save mode. because when you put it in that mode, it immediately lowers the contrast levels, if you haven't noticed. if not, try pressing power save mode and it'll immediately look like the screen dimmed a lil. it actually didn't and if you look closer you will see contrast levels dropped and display doesn't look as sharp and colors don't pop as much as other modes. almost cartoonish looking. display still looks good but not like when in balanced or normal. if you go from battery save back to another mode, you'll immediately see display switch back to high contrast level and colors pop again.
Ive been keeping mine in balanced mode except for when i play certaingemes like shadow gun. I couldnt be happier with battery life.

It's believable that reducing the CPU's max clocks could result in more power usage overall. It will still clock down and use the companion core in any mode (although a "turbo" mode that doesn't use it would be interesting for comparison), so the idle power consumption won't change. Reducing the maximum speed means it won't be able to use as much power at peak, but it may be forced to run at its (reduced) maximum speed for significantly longer, which uses so much more power than idle that the reduction in power from the lower frequency doesn't offset the increase in power from increasing the task length.
As an analogy, driving slower is more efficient than driving faster, because the faster you go, the greater the increase in power you need to maintain that speed (this is due to air resistance in cars, and the fact that power is proportional to voltage squared in CPUs). But that's only true up to a certain point: you don't get awesome mileage if you drive everywhere at 10mph, because it takes so long to get anywhere you'd have been better getting there 5 times quicker and then turning the car off entirely.
This is why battery life is so good in sleep mode lol how low the processor runs it's under 102mhz

good point. I also think that's only the case if you put it in battery savings mode and try to do more CPU intensive tasks. I would think that if you put it in that mode and only do more simple or less CPU intensive stuff, we would definitely see the best battery life in that mode.

I've loved my Galaxy SII right from day 1, but the phone's battery life has made it a complicated relationship.... I'm hoping to share my experience as a heavy user and how i'm dealing with the battery.
My usage:
I would fall into the 'power user' category. I'm rooted, on stock 2.3.4 (the update to 2.3.6 was pushed to my phone, but obviously failed). I'm often streaming audio podcasts, using Waze (a social gps program), and checking twitter and online forums and the occasional email or text. Bit of youtube in there as well. Bluetooth is on 10% of the time, wifi always, screen 1 notch below max brightness, no 'fetching' widgets.
My last phone, the iphone 4 had better battery life, but not incredibly so. During heavy use I would get ~6 hours. Standby was closer to 20 hours. I still had to charge at some point during the day, but it's different with the GS2.
Let's take a look at the Battery Usage in Settings....

With 4 and a half hours of usage, i'm down to 13%. That means I'm up at 8:00AM, and by 1:00PM my phone is dead. It would almost be hilarious if it wasn't so sad... Charging has become a critical part of my daily routine. I'm using an external battery pack (more info below) and charge off a wall socket
Solution so far:
I've been using the Energizer XPAL4001, a 4000mah external battery for $58.00.
The thing is great, and I obviously wouldn't make it a full day without it. However it's a hassle to have to lug it around which is why i'm considering getting the extended battery which I was hoping to avoid by getting the external. But it looks like I do need both solutions.
Solutions I'm considering:
I'm about to pull the trigger on a3500mAh Extended Battery + Cover off of ebay. It's going for $11.00 with free shipping, so the price is certainly right.
What do you guys recommend? Has anyone tried the battery I'm looking at? It doesn't have NFC, but it's $11. I'd love to hear from other power users and how they're dealing with things.
PS. Still love my GS2
I'd recommend using your phone less!!
Try an i9100 rom, much better battery life.
You are expecting too much if you want it to last all day long with that much usage.
Doesn't look like your phone went into deep sleep not once.
Try flashing UnNamed 1.3.2 or 2.2.1 and a custom kernal and use SetCPU to lower clocks/volts.
This should help you in increasing the battery life a little more.
Have you checked this thread? http://forum.xda-developers.com/showthread.php?t=1308030
What about the Korean 2000mah battery? You can see my posts on this page for more info: http://forum.xda-developers.com/showthread.php?t=1281777&page=11
It would be helpful to know how much screen time you are getting. You can access this by clicking "Display" in the screens you have posted above. Your battery is dying incredibly quickly. If your screen time is less than 2.5 hours you may have a rogue app that is running up your cpu. Use CPU Spy and better battery stats to help diagnose.
Sounds like you are such a power user that you might want to consider one of the 3500mah batteries. If you don't mind the size that is. Search the accessories forum to make sure you order the right brand as some cause boot loops. You will also lose NFC.
Good luck!

Sorry, but no. I would carry a second phone before using this one less. But it's a reasonable recommendation.

I'm not expecting a full day of battery life, but 4 and a half hours of usage in undeniably on the short side. Thank you for the insight on deep sleep etc. I'm newish to android and appreciate a skilled user's input.
As for flashing a rom, I'm really waiting for an Ice cream sandwich release before going that route. I'm aware of underclocking etc but think that I might get better results by getting the extended battery.

Time on: 2h 57m 20s
I will look into those 2 apps.
This is what I have for today with better battery stats.
/\ were you using the GPS? I was for most of my 4 hours of life.
what were you doing with your 2 hour 26 min of screen on time?
Hmmmm, 3 hours of screen on time sounds about right for the battery life you are experiencing. As far as that particular battery, I'm not sure... I would play it safe and purchase one people are linking to in some of the threads that are confirmed as working. The other thing you have to consider is cover fit- which is another reason to go with one people have posted experience with in one of the "Accessories" threads.
BTW: Not sure but the Waze app may be utlize GPS in a way that it consumes more battery than it posts in your battery usage. Not sure though.
Also, are you leaving the screen on unnecessarily, like while listening to a podcast. That's a pretty intense amount of screen usage for such a short period.
Let me know what you decide
Just for Reference
Here's my usage with the 2000mah Korean Battery.
Screen is off during podcasts, on during GPS. Waze affects my battery about as much as the google Maps/Navigation app.
As for the battery, I've heard others buying batteries that have been $50 and up, I could buy 4 of the ones i'm looking at for that price.
Someone out there must have tried this battery before.... I'd like to hear what they say first.

Install BBS (link) and cpuspy (link) today and then tomorrow make sure to reboot your phone before unplugging and doing your daily routine.
Once your battery reaches 20% post the BBS dump and screenshots so we can analyze it better and see what is draining your battery so much and how to improve it while you wait for your new battery.
I highly recommend flashing a UnNamed or ShoStock since it removes bloat and also SetCPU to lower the volts and set some profiles.
You said your new to android, so listen to others that have used it longer.

I use gps for about a minute today. Most of my screen on time is messaging web surfing facebook and twitter
Was your screen at max brightness or autobrightness? Autobrightness tends to set the screen way too bright.
After all, your battery history indicates 74% of the usage was display - so I think you may just have the brightness way up.
Full brightness + GPS + CPU usage is brutal on the battery, that brings total current consumption to somewhere around 650 mA. (On the Infuse, the battery would slowly discharge with a 600 mA charger at fullbright + GPS. The GSII just barely keeps ahead with 650 mA charge current.)
I'm getting between 26-32 hrs with the config in my sig.

Alot of good advice in this thread! I highlighted above what I think is killing your battery. Go with a debloated stock like ROM, research a bit on cpu schedulers and go with a conservative one, turn the brightness down and you will be on your way to duplicating your battery life. ;
Use Siyah kernel and the Thunderbolt (TB) script. They'll do wonders for your battery. As for brightness use auto or half way. We're lucky to have such boss screen with crazy brightness. anything above 70% hurts my eyes in doors lol. Auto should be 90% effective for your day to day use. Also try to avoid apps that sync or fetch data constantly and set things to push or to auto-update every 3-6hrs instead of 15min-1hr. Those murder ur battery.

I'm considering this, but I'm going to see what kind of increase I get off an extended battery alone first.
I've found it harder than I thought to try and compile battery statistics...however, that being said, what kind of times are you guys able to get, say with average levels of use?
I think the most relevant stat is the one for screen on time, the screen seems to be the biggest killer of battery.
In my most recent use, Better Battery Stats tells me that I've been on the battery for approximately 1 day and 12 hours, and that only 5 of those hours have been for the screen on. I'm now down to 15% battery, so in general, I think that 5-7 hours of screen-on time (with the lowest brightness) is what I usually manage.
How.about the rest of you guys?
how do you work out how many hours the screen has been on?
i mostly use my flyer as an ereader during the week...i get about 4 days usage from 100% to 20%, and have airplane mode on mostly

I use a very useful app called Battery Monitor Widget. I highly reccomend it. Its able to split my usage between awake time, screen on time, wifi on time, and Bluetooth on time.
That sounds about right for me as well, 5-7 hours of active usage. Obviously depends on what you're doing, but I use it extensively and struggle to get more than 7 or less than 5.

Yes. So from our two experiences, 5-7 with screen-on time is somewhat standard. This is why I'm somewhat bemused when people say they've been using the battery for a week! I'm left wondering...were they using less than an hour of screen-on time each day?
If 5-7 hours of screen-on is the average, then my definition of light-to-moderate usage is when I can stretch that out to two days before recharging. Keep in mind that my 5-7 stat is with screen brightness on the lowest setting, and with Juice Defender.
battery depends on use. I have had it last 48 hours with 6 hours screen time and I have had it go in 16 hours with 3 hours screen time. With all the diferent variations of this device, as well as custom roms/kernels and GB vs HC I am not certain there can be an expected battery life span

Yes, I think 5-7 of screen-on time is about standard.
I ran my test and used my Flyer (wifi only) mostly for light work. It lasted 11 days. I mostly used it for notes, quickly checked website couple of times a day and read emails. I have played a game once for 20 minutes and another 20-30min were spent on Plex and Google Music. Screen was on for 4h13m. Wifi on for 16H.
Here is what I figured from that test:
Runtime: 10D 20H = 260H
Idle: 43%. I didn't check how many hours it said it was on idle. But let's say 250H. 43%/250H= 0.172% per hour (standby). That's 4.128% per day. That's very consistent with my observation. So, if you run Flyer for 10 days, you will spend 41% just to have it on standby. It will die in about 24 days, even if you didn't use it at all.
Screen-on (Auto brightness): 4h 13m = 4.22H. In 260H it ate 40% battery. 40%/4.22H = 9.479% per hour. So in theory (haven't tested this), you can get around 9-10 hours reading books(?).
Watching movie also puts load on the cpu and power goes to deliver sound, so I would say you will be using around 12-15% per hour. Probably around 20% per hour while streaming. A lot depends on sound level and video material. Also choice on the player and codecs used might make a bit of a difference.
I get about 4 hours of video or 7-8 hours of internet browsing / kindle reading.
a little bit comparism

agree with mcord,
it would be better instead of comparing randomly to mention :
Device Type : Flyer WiFi, Flyer 3G or Evo View
ROM : custom/ stock ROM + Kernel Info + CPUSet
Customization : or tweak or additional widget (Juice Defender, Better Battery Safer)
then the usage of application and hours spent, something like this.

So, if you run Flyer for 10 days, you will spend 41% just to have it on standby. It will die in about 24 days, even if you didn't use it at all.
Screen-on (Auto brightness): 4h 13m = 4.22H. In 260H it ate 40% battery. 40%/4.22H = 9.479% per hour. So in theory (haven't tested this), you can get around 9-10 hours reading books(?).
Watching movie also puts load on the cpu and power goes to deliver sound, so I would say you will be using around 12-15% per hour. Probably around 20% per hour while streaming. A lot depends on sound level and video material. Also choice on the player and codecs used might make a bit of a difference.

Device : Flyer 3G + Wifi (wasn't brand new, so i cannot figure out the previous owner flyer usage)
ROM : LeeDroid 4.1.0 HC + Kernel 2.2.0 + SetCPU scaling on smartassV2
Costum : using HC Launcher with out any additional Widgets and no additional Android apps for preserving battery
Runtime:
Screen On - Lowest Brightness + WIFI and 3G always on : 3 hours with 55 % left, mainly using on e-reader, taking notes, market access.(no multimedia usage)
I had around over 7 hours after i switch to the airplane mode in the last 7% battery left, with similar usage.
Hope this helps for utilize the battery lifespan.
I have a brand new Flyer 3G and I get about 4 hours of mixed use out of it (Airplanemode with wifi enabled, lowest brightness, 70% browsing, 30% video). I'm running stock HC 3.55.405.1 with root. No OC or custom kernel. Do I have a faulty battery? Seem like most of you get better battery life. 70% of the battery is used by the display according to battery stats. Is this normal?

If you are using it for 4-5 hours straight, then yeah that is probably normal. You might also need your battery calibrated if that is your first time. It learns and configures itself a few times after you charge it.

If people are reporting 5-7 hours display on time, and you're getting 4 hours with 30% video, then no, I wouldn't say that that's unusual.
This is tragic. Such a great tab with such a big flaw. The iPad 2 has a 7000mAh battery and the screen area is twice as big, not to mention a much more powerful soc, and you get about ten hours use no matter what you're using it for.
Gotta be a bit more fair in your comparison. That was like comparing a house cat to a bobcat.
In all 7" tablets (including non-androids), I feel that right now the contender is the the express/flyer is the only one that reigns on top for the past year, and can't be beat for only ~$250 in today's market. The only thing the A100's have going for it are the AOSP experience, the Xoom is a direct competitor.
But if you want to compare battery life, the tf101 and prime as well as A5/A6's got this beat by a mile. Not to mention higher resolutions. Point is, these are arguments extraneous of a 7"incher tab.

Yeah, I guess I was a bit unfair. I'm just a bit disappointed.. Expected a little more juice from the battery. Anyway, for 2500NOK(about 450$) it's not a bad deal. Btw the pen is included in Norway(and other European countries, I think). And the pen is the reason I got the flyer. It's almost as good as using a Wacom board for drawing. I just hope HTC doesn't abandon the flyer or have done so already. It would be nice with ICS.

I knew I forgot something!
Rooted View, Gingerbread, GoLauncherEX. I disable the cell radio on each boot.
-About 33% screen brightness
-WiFi on
-Sync on
-Cell radio off
-Bluetooth off
-Location off
My View gets unplugged from the charger each morning, rides ~12 miles to work through non-WiFi country, sits on my desk at work and gets used maybe 60 min total at work, then goes home with me and gets occasional to moderate use browsing and reading mostly. By the time I go to bed and plug it in around midnight I am usually at about 20% battery. Less if I've been gaming a lot or watching video.
So all together my View is on battery for about 16 hours a day but only used 3 or 4.
I went on an overnight trip a few weeks ago and by turning WiFi off when I was on the road the View maintained battery life well.
It's just a basic test but here it is
1 45min Episode of Star Trek TNG Note 2 10% battery Drain Effective 1% drain per 4.5 Min
1 45 Min Episode of Star Trek TNG DNA 17% Battery Drain Effective 1% Drain per 2.6 Min
Both are using Cell Network not wifi.
DNA was set to auto brightness
Note 2 Full brightness
Too bad TNG is not in HD so that extra power consumption on the DNA would be put to good use.
Haha!
But it still gives you an idea on media playback.
I would say this is typical when camparing a phone with 3100 mah and one with 2000 mah

Let's be realistic, no one's buying the DNA for fantastic battery life. But you'll notice it's much closer to the N2 in web browsing. AMOLED does better than LCD on dark content (video) while the reverse is true on light content (browsing).

It doesn't matter. The browser test is done over Wi-Fi and the video playback test is using looped local content. Here's how they test and what the endurance number means.
The web browsing test is performed using an automated script which reloads a webpage every ten seconds. There are no flash elements on the web pages, so the playing field is even. The brightness of the phones' displays is set to 50% and we use a Wireless N router placed a few meters away to get full connectivity bars.
In our video playback test we measure how long it takes for a device to run its fully charged battery down to 10%, while looping a standard-definition video. We stop at 10% since most devices shut their video players at this point. The display is again set to 50%, and all radios on the device are switched off (Airplane mode).
Finally, our overall longevity rating gives you an idea of how much battery backup you can get on a single charge. A score of 40h means that you'll need to fully charge once every 40 hours if you do one hour of 3G calls, one hour of video playback and one hour of web browsing daily. Essentially, it's an aggregated and normalized score, which factors in the three mentioned tests along with the real-life standby power consumption, which we also measure.
Here's what they said about LTE.
The HTC Droid DNA has pretty efficient standby, which helped it score an endurance rating of 49 hours (that’s the time between charges if you do an hour each of calling, browsing and watching videos). While we would have liked to see a bigger battery in a phone the size of the HTC Droid DNA, it turns out that 2,020mAh are quite enough to keep the beast going. Just keep in mind that taking advantage of that fast 4G LTE connectivity will add further strain on the battery.
Things could be much worse though...
Note 2 - 3100mAh Battery - 10% loss means 310mAh was used during that time.
DNA/Butterfly - 2020mAh Battery - 17% loss means 340mAh was used.
IMO ... not much difference keeping in mind the better screen of the DNA/Butterfly ... I would vote for HTC here

But it's kind of like comparing a Toyota Corolla that gets 27MPG with a range of 343 miles to a tank to a Land Cruiser that gets 18MPG but has a range of 442 miles. The Corolla's great if you you can refuel somewhere along those 343 miles if you're going on a 442 mile trip. And since recharging phones is a nominal expense more is always going to be better. And being able to swap batteries is even better than that. But when the consequence is running out of gas any phone with a small-ish non-removable battery's efficiency only gets it so far. Obviously not an issue for light users or people that can top-up frequently. I had a Teg3 One X with a battery only 11% smaller than the DNA's so I've lived the dream.
Agreed .... What I can state from my experience with phones is that HTC's Quality/Aesthetics is the nearest that can be achieved on Android when compared to iOS (Again IMO, dont flame) ... And the way I see is that if I can carry extra battery in the pocket, I can carry a portable charger as well ... Would not have traded-in the slim figure of the Butterfly with thicker one just to increase little battery capacity.
And these have been my phones in past 3 months (no particular order) ...
HTC Butterfly (Current, Non-LTE)
iPhone 5 (LTE)
Galaxy S3 (LTE/Non-LTE both)
Note 2 (LTE)
Xperia V (LTE)
HTC One X+ (non-LTE)
...
The one thing I don't understand is why HTC doesn't learn and increase the battery size. They focus on efficiency which is really good. AFter 8 hours of standby my DNA lost 1% battery. But when you use the dna for video and on screen time it just drains too fast. It needs a bigger battery. HTC keeps sticking small batteries in 4.8+ Inch phones.

What is too fast? I consistently see 12-14 hour days out of a charge with lots of screen time and music, even with a couple vids thrown in there too.

Here's some updated figures
Note 2 with Power saving mode on lost 5-6% Battery life
DNA still 17%.
I'd expect between 10-15 hours of life on power saving mode just watching movies on netflix.
While the DNA will be dead within 4-5 hours.
That's the big difference. On screen time consumes the most energy and that's where the dna is lacking in battery size and it shows.
I really see no point to this thread. The note 2 has a gigantic battery, the DNA has average/slightly above average, of course the note will have better battery life. Anyone who is surprised by that needs to get tested.
The DNA still has above average battery life. Its not lacking in any way, it just doesn't have a monster battery size.

Not really. The only difference between S4 Pro and S4 is two additional cores which, when under load, draws more power. Likewise for the additional pixels and the need for a more powerful GPU to push them. Whether for the DNA or any other device people's satisfaction with battery life depends on the size of the battery and how much energy what they typically do in a day requires. So an individual can’t say “battery life is good;” only that it’s good for them. I lived with a 1,800 mAh battery on a One X and was fine with it because I carried battery boosters around. But I would never have recommended it to someone that battery life was important to. And it's not like HTC has to use smaller batteries, other phones on the list are as thin or thinner. At least with a 2,300 mAh battery the M7 forum won't be littered with "it's fine - no it isn't" battery discussions like all of HTC's other recent phones.
"At present, this is the same Krait CPU as what we've seen in MSM8960 in phones like the USA versions of the Galaxy S 3 and HTC One X."

Yes, the s4 pro has 2 more cores, which allows it to complete any given task faster and allow it to get back to idling quicker. And it is a 28 nm processor, which is more efficient than the note 2's 32 nm processor, which is the main focus of this thread.
Also, the DNA has a super LCD 3 display, which is super efficient.
The battery life on the DNA is on par with the gs3.
If people use their phone enough to be able to complain about battery life on their DNA than they should of known that they would of needed either a note 2 or a RAZR maxx.

HTC could have easily put a 3100mah battery in the phone, my point is that they always lack on battery size and capacity.
Last time I checked mine at around 3%, it had been on for 1 day, 18 hours and 7 minutes, with the screen on for 6 and a half hours.
I was also playing Shadowgun: Deadzone for about half an hour, as well as several other lighter games, and using Archos Player to watch videos off a LAN server on my laptop.
That's on stock rooted and unlocked bootloader.
So, what would you consider good battery life for your N10?

I never let it drop down to more than around 30%, simply because the battery lasts me very long. I get a week with screen-on times of 5 hours or so. I don't play games, I use it mainly for browsing, email, PDF reading and some note/todo apps. If there are power-hungry apps, the battery drops much faster - but if not, I feel it lasts forever, especially in standby, even with all sorts of stuff syncing in the background.
Unplugged my N10 from charge this morning at around half 7 and went to school and when I got back at around half 4, I had only lost 1% of charge. That was a very pleasant surprise! I was expecting to lose 5% AT LEAST

The only phone that comes close to 14 hours of screen on time is that single phone you mentioned. So it is far from the norm and is not considered "good" but is considered "great". Good category would be 7-9 hours.

Looks like I could do between 14-15 hours of screen on time before it completely died. I consider this to be really good. Displays take up a ton of power and the fact that we can have a 10" screen and still get more than half a day of constant, straight use if quite impressive to me.

Just curious of your settings, kernel and ROM...etc? Ive never seen anyone break 10 hours of screen time...even myself when I was undervolted using ktoonz kernel and governors lose 10% an hour which would translate to 10 hours of screen time. No gaming involved because that kill's the battery.
If your using ktoonz kernel would you mind posting your settings so I could take a look? Wouldn't mind more screen time personally . Thanks in advance!

It was on for just very small bits when syncing stuff. I leave it off almost always as it creates too much heat when playing heavy games and brings throttling on a lot harder, and I have no use for the extra power drain when I am reading a book, which is what I do most on the tablet these days. But I realize not everyone has the same habits as I do and does very different things. So leaving wifi off almost all the time isnt an option for some people.
The ROM is CM10 from WAY back when by Craig. I think it was built is mid to late November? I honestly still find it perfectly adequate for my needs and very stable. I keep coming back to it from all the other ROMs I have tried.
Kernel was a build of the KTManta kernel from ktoonsez, build was sometime in December towards Christmas time. It was the build right before he added touchboost to most of the governors. I am not a fan of touchboost as it has greatly lowered my battery life, but it sure does make things smooth I use that kernel because I can undervolt both CPU and GPU. I was using the PegasusQ governor, which the stock settings for it in this kernel as the ones I asked ktoonsez to put in so you dont need to modify the settings for any special tweaking. I did however lower max speed to 1.2GHz as that is plenty when doing most things.
Here is a remade config file with pretty close to the same options I had used, but compatible with the newest 1-29-13 build of the kernel and tweaker app:
http://www.mediafire.com/download.php?geaveoa5tj43zpo
I say pretty close to the same because I increased CPU and GPU voltages a bit in that config so everyone should be able to run it. Many would most likely have a problem with the config otherwise as the majority of users seem to not be able to undervolt their GPU hardly at all.

Here is a remade config file with pretty close to the same options I had used, but compatible with the newest 1-29-13 build of the kernel and tweaker app:

I say pretty close to the same because I increased CPU and GPU voltages a bit in that config so everyone should be able to run it. Many would most likely have a problem with the config otherwise as the majority of users seem to not be able to undervolt their GPU hardly at all.

Wow. You increased the voltages? Those are really low! Thanks for posting your settings. Really appreciate it

My iPad 3 got around 14 hours of constant use before it died so I more than cut my battery life in half going to the Nexus 10. I get around 5.5-6 hours of screen on time on my Nexus 10. I use the lowest brightness setting when I use my tablet. I'd love it if my Nexus 10 had better battery life but it is what it is. Maybe I'll sell it if Samsung comes out with a new Note tablet.

Kernel was a build of the KTManta kernel from ktoonsez, build was sometime in December towards Christmas time. It was the build right before he added touchboost to most of the governors. I am not a fan of touchboost as it has greatly lowered my battery life, but it sure does make things smooth

Ohhh is that what happened? I had some great battery life going on for a while when I first tried ktmanta back in December, and have been feeling kind of frustrated after "losing" it and not understanding why. Would you be able to share that version of the kernel so I could do some comparing?
just remembered he recently added the ability to disable touch boost for the gpu and cpu. Going to try that out and see if it improves battery life.

You can set touchboost to 0 in any governor and it will be turned off.
Ktoonservative is the only governor with a touchboost for both CPU and GPU. Very smooth, but ramping both up drains more battery. So you definitely wont get into that "great" range on battery life when using it. But at least it doesnt tank the battery so you can still get some decent life with it on.
Wish I had 10 hours straight to be on my tablet..... Thought I used mine intensively, but I only plug mine in at night. Use it for streaming video(rental movies.. Not really youtube) and a few hours online. Maybe 6 hours a day.. Never come close to getting near 40 percent or less.
I've been using my Nexus 10 for work and play today. About 13.5 hours on battery so far, about 6 hours screen on time, and my battery is at 57%. Screen brightness has been at 50% all day. This is pretty typical experience for me. Stock ROM and kernel, except for being unlocked and rooted.
... beamed from my Nexus 10 to your planet
I'm at 6 hrs of screen time and 12 hrs of standby time and the battery is at 37%. Running on stock everything with unlocked bootloader and root. I use it at 0% brightness almost all the time and have everything except NFC turned on.
I'm on course for 9 hrs of screen time but I think I should be doing better considering I'm using it at low brightness. Do you guys think using custom kernel will make a difference?

I watched the entire avengers movie in 1080p while on a coach a bit back, Took me down to 76% battery. My needs mean that makes the battery more than sufficient for me
Hello,
I was wondering how happy you guys are with your S21 battery life?
I used a Huawei P30 Pro before. When going to bed, I usually had 30% battery left.
With my S21, I now usually charge at 7PM. I cannot imagine, that my usage habbits have changed much since - especially since I was unhappy with the battery life from day one.
I did some Analysis:
Idle:
With battery-saver (Samsungs; in Settings) on: 0.73%/h - Not bad, I would say.
With battery-saver (Samsungs; in Settings) off: 1.93%/h -Not good, I would say.
Now, do I want battery-saver on? Not sure... Why did I buy a first-class device when limiting its CPU and refresh rate?
Screen-On:
I know that here, comparing is difficult...
According to battery historian the Screen-On discharge-Rate is 16%/h. That would give me a screen-on time of 6.25h - I am hot sure if this is good.
How is it for you?
What I also notice in battery-historian is, that when switching off battery saver (green bar below) I have significantly more Userspace Wakelocks. Yes, I was also using the phone, but if you observe the yellow marked time around 12-1PM, there are wakelocks without me using the Phone.

Some more Info:
Wakelocks:
In minutes, it is not so much, but in counts... 2500 seems a lot.
Is this normal? Or is there something, I could improve/fix?

I'm not having anything like your experience. I am a US user with Snapdragon in case that matters. You don't mention how much typical daily screen on time you have.
I am sure there are more expert people here to interpret all of your captured data. But I am wondering about fundamentals. Have you already configured:
Battery optimization for all apps that don't require background operation?
"Always on" display?
Display timeout to something minimal? (I set mine to 2 minutes; I can't tolerate anything shorter)
Hello,
that is interesting to hear.
Screen on time is usually around 4h. Then the battery is completely empty.
The 2%/h in "idle" mean already on a day between 7am and 10PM 30%. So, the idle usage is about 1/3 of my drain and thus clearly worth improving. But especially the Screen On drain of about 20%/h is too high, I think. This morning I used the phone for below 2 minutes and the battery was already at 98%.
Regarding Apps in Standby: The phone has put many apps automatically in the list of "APPs in deep standby". I have manually added some.
I have only few Apps never in Standby:
Kalender, Kalendar widget, Telegram, Threema, Whatsapp.
Always on display is off
Display brightness is set to around 50%. Refresch rate is "Adaptive" and Timeout is 2 minutes.
So, I think this is all reasonable.
Any ideas?
Best regards,
Hendrik
Sorry, double post

Hi, AUHD(best on for battery life) or older SW? I have with first beta 5-7h sot, while night when I don't use phone I have 0,2%/h drain, with screen on max 7-9%
Wow, more than Double for me.
What is AUHD?
I have all updates installed.
Software version, if you have latest version there will be something wrong with your phone, try to find apps causing that high consumption. And never put any app to deep sleep or sleep mode, and don't use battery saver. This has for me other effect than lower consumption. These three things I have disabled - wificall,volte and 5g, nothing more.
And on WiFi turned off mobile data, GPS and bt.

In fact you have transformed your S21, you have made a Nokia 3310 now ......
Do not stop the adaptive battery, it is the best innovation from Google that Samsung has included. The I really do not understand your idea of using a smartphone with all these options to cut .........

There is no other way how to safe battery when you own Samsung device. It's very bad adjusted this one ui.... I've got lot of devices, s21(all versions) is worst of all of them

I have the S21 from the start I have always held 1 day and 18 hours on average with 2 hours of stupidity, and I do not deactivate absolutely anything, gps, WiFi, 5g, Bluetooth, I leave everything on, and it works perfectly ... .... For the adaptive battery to work properly, it needs 7 to 10 days minimum ..... It does not do in a day .... And personally I have had all the galaxies since the 1st galaxy , I got them all. And many fail to configure it correctly. And above all, gave him time to configure himself on energy management.

Whit yours sot I have to charge phone every 8h, 3 times a day, this is not what a customer needs... I see you are fan of Samsung(I was also- S6,7,8,10 and now 21) but comparing to other brands you have sot from 5-11h with no restriction.
For last I will mention android auto, first time in 3 years I see the first device what can manage android auto, so many lags and no interest from Samsung to fix it...
I will also mention the good things because of them I still have s21, display visibility in outdoor, speaker sound, cameras.
Just use power saving mode with 120hz enabled and u will get 5-6h of SOT easily.
Hello,
I have factory reset the device now. I got 6h SOT now (twice of what I achieved before.
No Idea what the reason could be, though.
The only thing that I am not yet using again is Nova Launcher.
Greetings,
Hendrik
I also came from Huawei P30 Pro and I've the impression that I had more battery before.
I've a S21 (Exynos version) and I think SOT is around 3-4h.
Did you let everything in automatic like "smart wifi", 5G, Bluetooth, ... ?
I don't understand questions like this. S21 is basic model and obviously has shortest battery life. If you want a big SoT, open
Battery life tests - GSMArena.com
www.gsmarena.com
customize usage pattern and choose your phone for example S21+. If you have already bought S21, turn on 60 Hz screen, lower the brightness, reduce the processor frequency, turn off unnecessary communications and functions. I'm very happy with battery life for my tasks ))

S21 has a battery of 4000 mAh and a screen of 6.2 inch
S21+ has a battery of 4800 mAh with a screen of 6.7 inch
S21 Ultra has a battery of 5000 mAh with a screen of 6.8 inch.
Ok, S21 has the smallest battery but also the smallest screen.
I let everything in automatic mode like you can see on the attached screenshot.
I don't see the problem if we ask to someone if he let everything in auto or if he plays with Bixby Routine to optimize his smartphone.
I am also happy with this smartphone and its size but when I'm leaving to a place with power, I know that I need to take my power bank even in Batter Saver mode
I also thank you for your link. I can see, according to test result, there is a difference of 7h between S21 and P30 Pro. I don't have this impression
S21 has a battery of 4000 mAh and a screen of 6.2 inch
S21+ has a battery of 4800 mAh with a screen of 6.7 inch
S21 Ultra has a battery of 5000 mAh with a screen of 6.8 inch.

4000/6,2 = 645 mAh per inch
4800/6.7 = 716 mAh per inch
I don't know why in a place without power, for example, an option is needed "Turn on Wi-Fi automaticaly", Wi-Fi is looking for a router all the time.
