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.

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.

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.

I've done a bunch of different things to my phone to achieve this. I owe most of this result to scripts I have developed, I've put a lot of research into these, as well as my build.prop (Google "0vermind build prop" for that), I am not even using the memory values of supercharger, etc. I will probably be posting my scripts soon and how I did this, but just wanted to give a heads up. Long live the best phone ever made! The Droid x2!

Nice..looking forward to your work..
Now this is with what kind of use?
I can do regular texting, a little web search and marketplace downloads/updates and have around 19 hours and be around 20% with just the normal tweaks. (Probably 40% usage, 60% idle). I set the data saver to trigger at 11 PM (even though I always use it until late into the next morning) but by the time data saver is off (8 AM) the phone probably dropped 10-15% if I rarely used it. I'm wondering if this is at all any good since my idle is around 85% at all times so it looks like you trimmed that down.
This being my first smartphone, I think the actual standbye time is great but usage time is awful.
*edit: Just checked and running 2 Hours on battery and dropped 10% so I have no clue whats going on. I've noticed this phones battery is really random.

Mines been pretty consistent, and I've had wifi on most of the time, if you look at the screens. I don't text using standard texting app, I use Google Voice, which is said to use more battery cause it has to send a keep alive signal and it constantly redownloads messages.
That being said, I also have Trillian sitting in the background and have it on 24/7. It notifys me of texts, vms, calls from my business number, plus facebook. And I made a few calls, some short, some long. All that, 19 hours, and still 20% to spare. Heavy use still lasts pretty dang long.
And, if you look at my awake times, my phone never really goes into deep sleep when the screen is off, and it's suppose to, I think this is a software bug in Motorola's build of Gingerbread for x2. That's why I think I'm pretty impressed right now with this beast! Oh and Quadrant scores around 2900.
I have excellent battery life with my x2, the key to me was not using any of motoblur's social networking integration.. It consistantly runs and just gums everything up.. I use the facebook app and twitdeck when i want too, but dont let them update automatically (aka no unneeded connections to the web to download crap i can just manually update)..
Ever since then i get 2 full days out of battery usage if i need..
Since moving to Gingerbread I've been able to push the phone to almost 24hrs between charges, on very light usage days. This is with bg data services running (Sync on, corp email sync, Trillian, weather updates, etc...) If I'm using the phone for any significant portion of the day this drops considerably.
All I've done is frozen most of the Motorola/Verizon bloat.
The next opportunity I have to basically ignore my phone for 24hrs I will post screenshots to prove it.
That's with light usage though? I use my phone pretty heavily at times. Cause as you know from my signature, I run a business, lol.
I'm a heavy use phone user and I use my phone as my home phone. I've rooted and killed the motocrap with fire. I use setcpu to handle better CPU throttling and achieve 24+ hours on a single charge. I don't have any doubts the heavy battery use stems from the motocrap. I just cannot wait until CM7 or another minimalist rom becomes available with overclocking.

Do you happen to have any problems with setcpu actually making the processer stay within the range you set? It seems that no matter where I set the min/max it stays there for maybe half hour max then goes to whatever speed it wants to. The sliders don't change spots, the cpu just doesn't stay within the value set after a half hour. Can't future out why.

I am not trying to overclock. I am trying to keep my speeds lower to help save battery which I have been told IS possible. I know I can't go faster than 1ghz but I thought I would be able to keep it from reaching that to save battery life. Am I wrong
Overmind,
Is this with the stock bh5x battery? I can get upwards of 10-14hours on mine with moderate use.

I'm not so sure that the stock kernel will allow for any tweaking of clock speeds. I think you have to have a custom kernel to implement any clock or scheduler changes.

Not sure about that one... I use profiles to handle the changes rather than forcing the speed ranges through the set sliders. The profiles seem to work better anyway, they react to active content rather than set-in-stone performance. One thing to note, the profiles are only available in the paid version (IIRC). Changing the profiles would be similar to handling the changes manually or through custom scripting routines. Right now, I'm going on 15+ hours with 70% of my battery left. I had the OG Droid running over five days on a single charge. What I do different from those saying 1 day max charge, I have no clue.
So ETA on script release?

I shall try profiles then. I do have paid version. Thanks for the tip.
I consistently get 20+ hours with a stock battery, no scripts of any kind, with moderate use and data always connected. All I've done to achieve this is de bloat the hell out of the system apps, set my screen brightness to minimum (the thing its so dang bright anyways, you can hardly tell once you get used to the minimum setting) my wifi is set to never disconnect (I pretty much have a wifi connection 95% of the time) that's about it. I use adwEX, plume for twitter (polls every 3 minutes) gmail, google voice for visual voicemail, moderate amount of widgets (clockr, fancy widget pro, system panel, power control, uk news), I'm even running a live wallpaper (vortex galaxy, set to 100% speed).

You Can Underclock.
So here I am, finally hitting 50% 1d 5h 10m and a few seconds. I wonder what this would be like on the extended battery?
Let's get some info going on battery life.
I bump charged 3 times this morning so its time to put this bad boy to the test.
I have auto brightness off. WiFi 4g Bluetooth and GPS on.
Update 1
It's been just over 5 hours and I'm sitting at 74%. Moderate usage. Websurfing facebook one 20 min phone call. Not bad at all. Been on 4g most of the time
Update 2
my day is over, im home battery is at 17% and I used the phone quite a bit. Had to navigate for about 15 min in there. Used 4g most of the time, tho there was about 4 hours of Wifi usage in there too.
so that is about 12 hours of usage here. I bumped charged 3 times as i said. I dont think the "small" battery is an issue at all!
Sent from my HTC Rezound using XDA App
so far, i'm getting the same as my incredible haha..i don't have 4g here so, i'm on wifi all day
2 hours into it, 81%..that's NOT bump charging either.
2 horus into my 1500mah inc, i'd be at like 75%. so i'd say SO FAR she's doing well..
this is also wtih 76% display, using it for 48 minutes outta those 2 hours. not bad!! and she's idling at a cool 24.4 degrees C here...battery left widget is a good widget
I'm seeing the same as the dinc too. Battery was halfway down at 4 hours of running time. That is with 4G enabled, WiFi off, BT off, GPS on. Screen Brightness on medium. It seems to be on pace to last 8-9 hours. I did stream some Pandora and visited some websites. Also, service in my building is spotty so my phone will search for a signal and switches between 3G and 4G all day. The battery shouldn't be a problem on this phone with normal use.
10 hours, 50 minutes on battery so far:
45%.
not bad! this isn't 4g though, this is all 3g and wifi..pretty much mainly wifi. display 68% with it being time on for 1 hour and 48 minutes.
this things pretty much gettign the same battery life as my inc, so i'm happy with that. a 14-15 hour day is what i was expecting and will be easily done i think!
Weeeeeee forty or so straight minutes of use..texts, browsing, music listening...just trying to kill the battery to recalibrate battery left widget...lol gotta love the drop. I just hit ten percent now, at like 13 hours off. Awesome

What are the "Power" settings for your guys? Performance, Normal, or Economy? The phone comes out of the box in Performance mode, but I toggled it to Normal which in turn turned off my sync (how that is normal I have no clue) and who knows what else.

same, i'm still on performance...thats hwy i dont like those built in settings..i want to change stuff to how I use it, ya know? i keep sync on for google, facebook and weather, and that's how i want it haha
but i think it's a good idea like if you're out and you wanna quickly change power modes.
It is good if you have like 25% left and need a quick way to prolong the battery life. I think it is a good idea because not everyone is an expert on this stuff.
agreed; i'm also interested in checking out that low power sleep mode..seems like a good idea for people who leave it unplugged overnight...just have it turn on a few minutes before your alarm clokc and bam!
id like to see a thread in regards to how long it lasted using constant 4G data with the screen on the whole time.
Constant 4G data would hit a data cap before the battery died I bet.

do you mean set the screen to never turn off, and then setup a download and let it sit until it dies
i can do that, i have the oldschool unlimited plan and im at 7gb right now. I cant do it today because im at school, but I will do that tomorrow and let you know

not anymore than any other phone. I came from the dorid charge, and we talked about the same thing. and before that I was using the Dinc, and again, we talked about the same thing.
Pretty sure we need to start expecting that screens use more power than the rest of the phone.
The same is true on a laptop.
The poster above me is suggesting a 'stress test' of the battery by turning on all its high power usage abilities and then seeing how long it will last. 1 hour, 2 hours.. I did this on the droid charge and it only last 1 hr 45 min
I thought I posted in this thread. I set my settings to Normal instead of Performance. I haven't noticed any lag or any issues. I did notice it turned off LTE, set the WiFi settings back to 15 minute sleep, etc. So I changed those settings to my normal always on, keep the screen brightness low, and have seen ~1/3 better battery life with the same 'play and experiment' usage. Not exactly scientific, but I feel as though I have used it equally on both settings.
First full day of use and I got about 8 hours of battery life. (Heavy Usage) I work in a warehouse alone so I'm always playing music and use my Rezound as an mp3 player.
About 6 total hours of music playback, some faceboook every break or lunch, some twitter and lots of text messaging about 100 txts and about a 15min convo within the 8 hours. (What really killed my battery was the music playback)
Everything was on gps, 4g, auto brightness, auto sync etc.
8hr Shift started with full battery, shift ended with dead phone. Gets the day by, but for those that do not use over 6 hours of music playback, I'm sure you will see about 15hours+ on your device.

Just got the standard Rezound battery for my Thunderbolt 21.80 after discount. I will report usage in a few days after some battery calibration and full charges and discharges. So you can compare this battery on Rezound with a rooted thunderbolt with custom kernel.
On battery 4 hours 50 minutes with the settings I posted above. Normal usage, on 3G/4G 74% remaining.
After 8 hours, 5 of those on 4G while the rest on Wi-Fi. 3 Push email accounts, some Facebook, and web browsing. I'm still at 80% battery life.
Hell I don't know what they did to this phone but I might just return my extended battery as I don't think I'll ever need it based on my light/moderate use throughout the day. Can't wait to see what a debloat/kernel would do to this phone. My Bionic which I had before with a higher capacity battery would be sitting around 40% by now.
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.

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.

I think i'll need 3500mah too. I'm aware of the boot loop stuff, but I can't find clarification on whether the battery i'm looking at ( ebay link ) will have those problems or not... I would like advice on that.

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.
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?

Probably 14+ hours of constant use like some of the smart phones (like the droid razr max). Probably unrealistic with a 10 inch 2560x1600 resolution. At least for now.
On the nexus 10 on a good charge cycle I can get 10 hours of consistent use including games, movie, and surfing the web.

I'm 100% out of the box stock and usually get 5-6 hours screen on time and the total on time can be anywhere from 1-3days. I usually keep location services off unless needed.

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.
My tablet can get over 13 hours of screen on time:

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!

My Tab2 10.1 had impressive battery life. Standby power draw was minimal and simple tasks like surfing the net gave me much better battery life than my N10. I'd be happier if they could match it what I could see on the Tab2. I know there isn't a number associated with that so take it fwiw.

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.

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.

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.
Sent from my Nexus 10 using Tapatalk HD
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?

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.

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?

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

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 .........

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.
