Self Charging

Battery was 28% last night, the phone gained 3% overnight when It usually drains 2%, no usb connection as you can see in the graphic. What could cause this behavior? I’m just curious.

Perhaps its an issue with your battery controller. It was projecting a certain loss of battery but when it did not after waking from sleep it assumed it had charged and displayed a higher %?
That is completely conjecture based in no fact other than those made up by me, so please take it with a grain of salt. =)

i'll keep saying this, but nobody wants to look at the nexus s battery driver code. seems the phone is based off voltage tables, which fluctuate under load, and hence when you charge to 100% and unplug, it drops to 97%. because the voltage drop.
same could apply to this situation, very often you can see your voltage drop like that. especially if you left the phone idle all night after using it hard prior. voltage drops then increases.

Yes, I was using maps very hardly (at least in comparison to the rest of the day) and that’s the reason of the fast drop in the graphic, then the phone went sleep for almost 7 hours. I’ll take a look at what you’re saying about voltage tables. Very interesting info here.

you were using maps right around the time of that drop? then yes that's the reason. i wasnt directing the "code review" to you lol, just more of a general thing that was discussed in the forum previously. sorry
but this would definitely show, in my opinion, why there is also the 100% to 97% drop when taking the phone off the charger. voltage drop always ocurrs here.

No reason to be sorry about, I didn’t take it that way; I just like to learn new stuff about how things work.

its the battery meter. you probably rebooted. the battery meter in android is known to be inaccurate. sometimes after a reboot it can gain or lose percentage. ive gained 25% before after rebooting! in reality, you didnt gain anything, its just the meter being off by a bit.

I just want to know how you get nearly 4 days of use out of a charge!
Don't you use your phone?

I haven’t seen this after reboot, this happened after awake and it wasn’t sudden. Phone without signal in the graphic is the “airplane-mode” It wasn’t off. I know that battery didn’t gain any charge, of course, It’s just the weird behavior of android reading battery information.

lol, yeah, It was a very quiet week.

it would be awesome if you could test this if you dont mind. turn your screen brightness to max, make sure your on 3g and not wifi, open google maps and scroll in one direction for about a minute or 2, check the battery percent and voltage. then turn off the screen, leave it sit for a few minutes, then see the percent and voltage readings.
maybe try a test a few times just for fun...you wanna place as much load on the phone as possible, so maybe even turn on the camera flash?

does any body else has an easier way, or can recommend a market app to test the battery life by using full features?

Quick test here:
Beginning with 3728 mV, stress the phone a little and It drops to 3622 mV, then I let the phone sleep for couple of minutes and after wake it battery shows 3730 mV. It seems to show higher values than those that were present before sending the phone to sleep. What could be said about that?
I’ll do another test with full charge and more stress, but for the moment, my phone is charging, yeah…. Finally.

its too bad my app (my sig) doesnt work for the nexus s, because i just recently added real time voltage vs current graphing, taking 2 second readings, for these exact circunstances. its fun doing these types of tests on my n1. but the battery driver and model is too different in the nexus s to use the app...
n1 doesnt use voltage at all for percent readings, but my hunch from code was the nexus s does. that's why i was so curious. check out some screens though for fun. you can really do some interesting tests with such high sample rates.

Help with my battery drain please?

When I first got my S7 the battery seemed to be draining pretty quickly, being totally unable to get through a full day without needing a recharge. In fact it would get down to about 20% within 7 hours. One night I charged it to 100% before bed, and then left it off charge, and it used up 15% overnight. I looked up some other people's reports, which seemed to suggest that the normal battery drain overnight should be closer to 5%. In fact on the "reviews" section on XDA, a lot of people seem to say that 1% overnight is more normal. I do use the AOD though, which I hear might use up 1% per hour? so I should be maybe getting between 8% and 10% overnight I guess.
I have done a full factory reset, thinking that perhaps it was being caused by an app or setting that had transferred during the NFC auto transfer process, so I did a clean install of everything, followed by wiping the cache. Fresh tidy install. Battery definitely seemed better, but still not great. I did another test last night, a shorter one but still should be enough info for people to help. (hopefully).
I've included the screenshots, which show a 7% drop in battery in 3.5 hours, so a typical 'overnight' is still going to be about 15%, way higher than 'normal' apparently.
I do leave everything running overnight, but from other user's reports that shouldn't matter. I have wifi set to turn off on sleep unless charging. Doze seems to have worked this time (which it wasn't before my factory reset), though it doesnt seem to have helped the battery drain much.
The weird part is that the built in battery app is saying GooglePlayServices is draining a lot of battery, but GSAM seems to think it hardly used any battery at all....

My main reason for chasing after this is that I have just come from an xperia Z5 compact, which will happily get me through a day at work and to bedtime with 40%+ battery left, and could potentially last through two days. True, it has a smaller screen, but then the S7 has a bigger battery. Any help is greatly appreciated.

Since it is not an app that is draining the battery, which means there are two possibilities.
First one would be that certain settings are draining the battery, like all the smart stuff and the beacon that always searches for devices nearby.
I personally don't use AOD because I don't find it that useful, plus it uses quite a lot of juice. So just look through the setting and turn off everything you don't use.
The second one would be the firmware.
I once had an update which made my battery just suck. I got quite fed up with it and decided to move to a custom rom and I've never had any problems since then. I also use greenify and L-speed to make my battery last even longer and since I am a quite heavy user, but with mixed use I get about 15-10% by bedtime.
Hope this helps you to fix your problem.

Changing rom isn't really an option, as there is no way to do it without tripping knox. Not worth the effort at this point.
I already have the WiFi and Bluetooth constant scanning turned off, and WiFi turns off when the phone is asleep (or is meant to anyway).

I would try to flash a newer firmware via odin. That shouldn't trip Knox. But if that doesn't help then it might not be a software problem anymore.

I found that the AOD was preventing the phone entering Doze, disabled mine and got a lot better results overnight, down to about 2-3%
Lived without an AOD for years, don't need one draining my battery now

Same, though I do like the feature at times. If it actually showed notifications for whatsapp or facebook I would definitly keep it, but it only shows texts and calls (and I rarely get either) so I can live without it.

If it had a setting to stay off unless you tap the screen, then show for say 5-10 seconds, and turn off again, and like you say, had useful notifications to show, then I might, but as it is atm, it's just a pointless battery drain

Actually, something I learnt over the weekend (and you may know about already), is that the AOD screen will turn off if you turn the phone face down on the table, or have it in a pocket. I believe it uses the proximity sensor. When you pick it up, it turns back on.
Also, according to this article, it uses roughly the same amount of power "turned off" due to the proxy sensor, as it does when it's totally disabled. So maybe that's an option.

Yea I remember reading about the face down thing a while back, didn't have a case back then though, and wasn't going to put the phone on it's screen, still, seems like more hassle picking it up and turning it around to see the AOD than just hitting the home button
Maybe 7.0 will improve AOD, if it was useful I wouldn't mind the drain as much, tbh I'm sitting at a PC most of the day anyway, so for the time I can just look at the computer, if I get a text the screen on the phone turns on anyway, and the only other thing is WhatsApp really, and I need to turn the screen on to reply on there, so tbh, AOD is pointless whichever way you look at it, for me anyway

I actually have the "easy on" setting turned on, so all I do is wave my hand over the screen to turn it on. Even easier than pressing the home button haha.

lol nice, I turn all that stuff off, don't like my phone waiting for gestures, accident waiting to happen
I especially hate WhatsApp when you are listening to a voice message, touch the top of the phone to move or turn it slightly, and the proximity sensor thinks you've put it to your ear and stops the message

The proximity sensor is running all the time anyway, so it's nothing extra. Though I do agree that it is sometimes annoying when it turns the screen off when you don't want it to.

Yea it's not using any extra resources, but I don't want to activate something without realising because I reached over my phone to pick something up off the desk lol
The WhatsApp thing doesn't turn off the screen, it just stops the playback of the voice message, PITA

Update: So I tried it last night with AOD turned off, and the battery drain.... was basically the same. Still averages out to about 14% over 7 hours. Hmm.

Well sony is known for a good standby so nothing you can really do about this but a full charge on the s7 should het you to 1 full day atleast so turn of sync and locations.

I have this setting on too. I wonder how much power this little feature costs? To have the sensors always on and looking to identify the exact right circumstances to fire up the display can’t be for free.
BTW it works great and never fails or lights up at the wrong moment for long. The phone has to be quite still (accelereometer) and the proximity sensor has to be triggered. This leads me to believe that quite a bit of the battery power goes this way. What do you think?

Well my only worry is I have a glitch or a bad battery, as a lot of reports on the xda reviews pages are saying that they get overnight battery drains closer to 5%, which is a lot less than I'm getting. This means my daily use is always going to be shorter, and my battery will wear out faster.

Well I know the proxy sensor is on for the AOD anyway, because of the auto shut off. I assumed it was a sensor that was just always running, like the accelerometers. They don't use much power really.

My wifi is set to turn off during sleep, unless the phone is on charge... Though the GSam app seems to say it's always on? That app seems a bit innacurate on other things too though, so I dunno if it's just cos the phone isn't rooted that it's not able to see things properly.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy S10e before depleting the battery.
Then, drop a comment if you have anything to add!

Exynos S10E, Nova launcher, bixby off, dark theme, stupid apps disabled/uninstalled, looking about 6-7 hours SOT!

Playing movies and stuff will get a lot more out as well, screen is a battery sipper. CPU is a bit intense so turn on the "Medium power savings" option to down the cpu to 70%, you'll get SD845 performance which is still good, and a solid bit more battery too!

The new exynos might be faster than the S845 on paper but YouTube speed tests put them neck and neck on a good day.
https://youtu.be/yk2Nysa82ig
If performance needs to be lowered then the battery is too small.

I have found a rare problem with the s10e display.While increasing brightness slowly i mean really slowly i can see display color changing from normal to slight purple this happens again and again while dragging to its max slowly and steadily.can be seen on white back ground at night (low light).is this normal let me know bro or anyone with the s10e thank you.?

Same thing I also noticed in S10E Indian unit.

Is it very slight? I'm trying to go slowly from lowest to highest brightness and can't see it, maybe a sliiiight purple but mostly white..It stays white.. I'm comparing to an iPhone and the screen is a bit different in color temperature but not extremely purple or anything.

Very poor battery life
Samsung Galaxy S10E is javing very very poor battery life.
I got this device two days back. I charged it to 100% and started listening songs on Gaana.
Battery drained from 94% to 4% in 6 hours.
Gaan used 69% of battery in this time period. I diddo anything else other than listening to songs. I had LG G7 Thinq earlier. That phone used go drain max 30-40% durinf this period despite having lesser battery.
I am utterly disappointed with battery life.
Also, can anybody guide me on how to add screenshot here?

I have the SD version. My first full day of use (noting that it will take time to "settle") was pretty good! It was off the charger 3am-10pm. I plugged it back in when it hit 6%. Managed to reach 5H10M SOT, which wasn't bad - it also included 1.5 hours of gaming (Langrisser, which drains battery), Chrome, Reddit, Hangouts, etc.
Since then I have enabled Medium power savings mode and am hoping for slightly improved battery life and SOT as a result today. I already use dark theme and keep brightness around 30%. I also installed Naptime today which I hope will help further improve battery.

5 hours SOT at 15%-20%, but I have to turn on power saving when I'm at 30%-40%, battery life is not impressive it's just ok.
I feel standby time sucks a little bit, yesterday I was losing like 1% every 30 min with power saving on.
P.s.: I have one UI without any launcher and just time/temperature, notes and google calwndar widget in my home screen.
2nd p.s.: I have noticed that the s10e handles well with apps that are power consuming like Maps, Waze or Youtube.

Battery has been pretty good on my end.

You guys decide, bought the phone last week:
using Nova, bixby routine to control autosync and other components, animation x.5, night theme on ,goodlock real black notification panel with blur effect cancelled and disabled Facebook services.
P.S using exynos, s10e

Battery life is a joke on mine, maximum SOT I would get is 3 hours and my use is not even heavy, mostly on instagram and snapchat.
Night mode on
Nova
Goodlock
Bixby off
Google assistant hot word is off as well, I thought it has a hit on battery but it doesn't.
Battery usage is useless as well, it does not show what drains the battery, well it shows "Android system" as the second one after "Screen".

Thinking of getting the s10e exynos;can someone share battery usage while gaming or using navigation?

Pretty decent battery life considering the battery size. This is worth a mix of both LTE and Wifi. A typical working day.

s10e snapdragon (g9700), 20% left, 6h SoT and 24h with normal use (social networks, spotify, etc) over wifi and LTE, performance mode. Phone's still learning usage to improve battery life. It's first charge, hope to reach 7h SoT. Google app disabled btw
EDIT: added last screenshot, with 7h16min and 28h of use.

Brand new sm-g9700 s10e model.
Did a charge to 100%, and this is the result after 1st charge.
6hrs sot
39% battery left
Sensational. I'll try for 7 hrs.

Fantastic.
Made it 7hrs sot with 32% battery remaining.
Could crack 8hrs if I want to , but leave that for another time.

Note 10 Plus bad standby battery drain

I've had my AT&T Note 10 plus for over a week now, and for the first week the battery life was stellar. Three days ago seemingly out of nowhere, battery life had tanked. Some context - I came from a Note 9 which had fantastic battery life. Location on, widgets, notifications, etc were enabled. I feel I shouldn't have to yield to or cripple my phone to get decent battery life from it so I refuse to do that on a device that costs this much. It should just work.
Anyway, fast-forward to three days ago with my note 10+ - same settings and everything as my previous note 9 - and out of nowhere the battery life just starts to tank. Android System is seems to be the drain, but I'm not sure what in there is causing it. The phone is constantly warm. As an experiment, I've put it on airplane mode now with wifi still on and the phone has cooled down but I'm not sure yet if the battery is being drained less or not as it's only been a few minutes. But, I am losing about 6% battery/hr not even using the phone. That is rather unacceptable after it having worked just fine the first several days I've had it. I refuse to disable location and do other seemingly band-aid tricks to help the battery along as I don't feel that really solves the issue and should be unnecessary for a device that costs this much money. I also refuse to factory reset unless I ABSOLUTELY have to because these phones are a pain in the rear to setup, even with Samsung/Google's restore. So many settings to go in and manipulate.
I hope this resolves itself or I can get to the bottom of it somehow. I really love this phone and really don't want to go back to my iPhone XS Max over a battery issue but it is just unacceptable for the battery to drain like this with little to no actual use of the phone. The other night by the time I had placed it on the charger, android system was up over 30%...
is anyone else experiencing this problem?
I apologize if this has been discussed before - I couldn't find anything similar.
EDIT
After putting the phone in airplane mode (wifi left on), it has cooled down and battery drain seems to have improved. According to the battery graph it looks like the phone is also finally going to sleep. Previously the graph went straight down to the right with no flat spots.
What could this be? My cell reception hasn't changed and I'm at wit's end

I've had my AT&T Note 10 plus for over a week now, and for the first week the battery life was stellar. Three days ago seemingly out of nowhere, battery life had tanked. Some context - I came from a Note 9 which had fantastic battery life. Location on, widgets, notifications, etc were enabled. I feel I shouldn't have to yield to or cripple my phone to get decent battery life from it so I refuse to do that on a device that costs this much. It should just work.
Anyway, fast-forward to three days ago with my note 10+ - same settings and everything as my previous note 9 - and out of nowhere the battery life just starts to tank. Android System is seems to be the drain, but I'm not sure what in there is causing it. The phone is constantly warm. As an experiment, I've put it on airplane mode now with wifi still on and the phone has cooled down but I'm not sure yet if the battery is being drained less or not as it's only been a few minutes.

I use Naptime from the play store by Francisco Franco and no as the title of his app says you don't get 9000% better battery. You'll need a couple of adb commands to get it to work it you're not rooted.
https://play.google.com/store/apps/details?id=com.franco.doze&hl=en
This is a quote from Franco - Unbelievably improve the battery life during idle of your device by empowering Android's built-in Doze power saving functionality. It supports Marshmallow, Nougat, Oreo and now Pie. It features more options for rooted devices, but it'll also work if you're unrooted.
Naptime also allows you to disable WiFi, mobile data, location & bluetooth during doze for that battery life /flex ?

I find that I'm losing around 1 to 0.7% per hour is that normal or considered good? The other night my phone was at 95% I woke up 6 or so hours later and it was a 89%. I'll need to do some thorough testing, but I don't know what to make of those results.
Anyone on here have some advice on weather that idle time is good or bad? My device is an unlocked n10plus running Snapdragon

-If you charge to 100 and put it next to your bed. How much is it next morning?
-do you use the led cover?
-are there any less known apps in your list?
Switching off wifi, Bluetooth etc is useless. These are efficient enough nowadays.
I tested these kind of "tricks" and no difference after my nightly sleep test.
Sometimes an app like evernote, google foto's or journey is downloading a lot of data in your new phone.

With all my last Notes I get a .6 till .9% per hour in a situation where i put my Note next to my bed and do not touch it during sleeping hours.
I live on three different locations, in different countries even, and that shows some battery consuming difference. Routers and provider locations are not the same.
I have more than 180 apps installed. No games however.
I am not rooted, but use GSAM battery monitor. The quickest way to see the hourly consumption.
Factory reset means a full day work for me. E.g. banking apps need a lot of tuning. Even using Google and Samsung restore.

I charge it overnight while I'm sleeping. No lesser-known apps installed, no LED cover either. Not rooted. this literally happened out of nowhere after days of it being great. Not sure what could have happened, or if it's something on ATT's end? I don't know where else to look. I'm with you on the factory reset. It's such a waste of time and will take up hours.

mine also been facing this battery drain issue since day one. Tried using naptime just now and it improve my battery life ALOT!! Thanks for the suggestion

Pls try to charge it before going to bed and leave it to see how much it spends overnight w i t h o u t touching it. If it is higher than 1+%/hr something is wrong..
I buy a new phone every year because I am nuts. But I always register in Evernote my findings.
Frequently the power consumption is higher in the beginning, because a lot of background activity like data reading and background update of software.
If it is more than, let's say 1.2%/hr during overnight sleep it is not ok.
I am doing this test now with my Note 10+ 512 (Yes i am nuts, I told you) and will inform you later.
After seven hours .8%/hr which is normal.

I can tell you right now that it's losing 5-6% an hour just sitting there. The phone has been set up for days now so I know it's not the setup process. Like i said, it was fine for almost a week, then out of nowhere this happens...

Pffff, you have a problem. So in settings/maintenance/battery there no apps with high use?
After just rebooting the phone the consumption starts immediately?

Yes...I know I have a problem...Android System is the culprit. Beyond that, I do not know what in "android system" is causing it. Perhaps a wake lock bug? A wifi bug?

It's always the same with my Samsung devices it's rediciculus Samsung. On your note 10 or note 10+ before switching to flight mode set the network setting to 3g only! In 7 hours you will loose only 2% battery instead of 8 or more. Same was on my note 9 but Samsung finally patched this behavior a few month ago. Now the same with my note 10+.
This problem is only for the flight mode. So you can test 3 things in 3 nights. You have 3 options before going in flight mode. In network selection choose 3g only. Than watch what happens over night. Next time you choose 2g/3g only and you can try it with 2g only.
For me doing so 1-2 % battery drain in 7-8 hours.

I've pretty bad reception with 4G. But no crazy 25% drain over night, more like 4-5%. And that's with the non plus Note with exynos.

With naptime, do you get notifications instantly? I have auto sync on all the time, is there any issues around this?

Just bought a new galaxy note 10 and overnight from 100 % i have 57 this morning. Whats going on?

Is this normal on note 10 plus battery health?

My N10+ is about 3 weeks old, but I found, like you, that after a couple days of stellar battery life my idle was starting to drain pretty fast. Going to bed and waking about 6 hours later I was missing around 20%. This is with all apps closed, WiFi, BT, Location, Link to Windows, Mobile data, NFC, Sync, and AOD turned on. I turned off AOD, NFC, and Link to Windows. My battery drain since, for the better part of 2 weeks, has been about 5-6 percent. Around 1% an hour while sleeping. I don't know how I can help, but I hope this does. I honestly can't complain about this battery. I have been getting 6-7 of screen time before having to charge around 10%.
Edit: also turned off edge lighting, which I had enabled before.

ehm so you made your top shelf 1000$ device into a feature phone ... that's no solution

I don't remember saying, "Here's a solution for you!" No, I simply posted what I did to stop the horrible battery drain that I was experiencing.
Also, I spent the $1,100 on this phone and I'm pretty sure I can use it however I want. Feature phone, paper weight, fish tank decoration..:good:

My N10+ has been sat on my desk and not used for 4 hours yet battery has gone from 100% to 78%.
I don't know how this is acceptable.

I have the reg note 10 and ive been battling this for a couple weeks. nothing seems to keep the system from sucking the batter dry. Standby life is a joke. i lost 40% today with the phone on for about 10 hours and 30 min SOT while i was at work. I cant figure out whats stuck in the system, tried literally everything

Question Adaptive Battery or not?

So I have a new Pixel 7 Pro and after being away from Pixel devices since the 4a I am back.
I am used to turning adaptive Battery off on my Samsung devices because generally it throttles performance. Generally doesn't seem to increase battery life much.
Does Google implementation work better? Do people use adaptive Battery?
If you do why? Have tried it with it off and on and seen any difference?
Does adaptive Battery affect performance?
What are people's experience with it here?

I use it and unlike on my Note 20 Ultra all apps that run in the background like my smart thermostat with geofencing, blink cameras and so on all keep on running. On the Samsung that was always problematic. had to use macrodroid to sort of keep them running and to get geofencing working.
Battery life on the p7p is stellar too,

So most people use adaptive Battery.
Anyone with experience with it off?
I guess most people don't seem to really care?

I have never turned it off because I've never had any problems with it and I expect that with it off, battery consumption would greatly increase. Admittedly I have never tested it though so maybe that's what I'll do today.

I'm running Android 9 and 10 on Note 10+'s. I never use it as it doesn't work. Turning that junk on isn't the same as hand optimizing the phone, not by a long shot. Even with degraded battery at about 80% of its original capacity I get 9-10 hours SOT.

How long does it take charging time for you? I put it at night and it gets charged after 6 hours? Is it by purpose?

Yes, it remember your usage pattern. It will try to complete the charging process around time you wake up in the morning. Like, in my case, it will only hit 100% around 6a.m

that's adaptive charging not adaptive battery

There was an issue with losing granted permissions when adaptive battery is on. I still have it happen sometimes.

So are you saying that "adaptive charging" has been the reason for the late charge? My goodness. I will try today. I thought I had a defective battery. Lol

Yes it times the charge by when you will be unplugging it in the morning or whatever so that it will reach 100% when you're ready to grab it. I have that option office cause I just wanna charge as fast as possible in case it's needed unexpectedly. Adaptive battery so far works better than whatever the equivalent for Samsung was.

From what I understood from Google documentation : Adaptative charging will hit the 100% charge, few minutes before your alarm time. For this feature (that is supposed to protect the battery) to work, you need to have the alarm setup between 6am and 10am.

This actually seems quite good without adaptive so I'm just going to leave it off. In fact I was doing some 5G speed testing using Network Signal Guru on this charge and I would have expected something more like 10-11% screen on drain as a result. It was hovering around 6% before that testing.

Very helpful information. Thank you!

I have had both adaptive features enabled since I got the phone from Google.
Charging speeds seem just like normal? I didn't know the longer charge cycle is only enabled if you have an alarm set on your phone? I use a regular alarm clock but I may try and set my alarm as I charge the phone tonight. Would be interesting to see if it does something like a trickle charge.
It says adaptive Battery learns your usage patterns and optimized charging speeds based on that so I just thought that was it and every time I have charged the phone it seems to charge pretty quickly and get slightly warm. Depending how low it is around an hour to an hour and a half.

If you have your alarm set some time up to 10AM, it stops charging at 80% and then trickle charges to 100% right before your alarm goes off IIRC. I don't use it because I don't have an alarm set before 10AM lol.

I am going to leave it off for a week and I'll report back with my results. So far though, it almost seems better to just leave it off, which is weird.

Gookill Adaptive battery never worked going back to Android 9.
You can see its status real time; Developer options>standby apps.
When off all buckets show as active and their states can't be altered. When on the bucket states vary and can be manually altered, which doesn't seem to do a damn thing except use more battery and cause erratic behavior especially with bluetooth apps.
Instead, target the hogs individually, altering background battery/data usage in individual app settings doesn't invoke adaptive battery or alter the standby apps bucket state.
They call it Gookill for good reasons. Lol, every dumb bunny thinks they win with Google...

I have generally found adaptive Battery only throttles performance but doesn't really offer a significant benefit in battery life. My experience with it has generally been tied to Samsung devices though so I was curious if there was any difference on Pixel devices.
I am of the opinion that if you let a chip work as fast as possible it completes tasks faster than throttled and that actually helps with battery life. Basically throttling may give you a slight battery advantage but the difference is generally insignificant but the hit to performance is generally real. So you get almost the same battery performance but better overall performance without any adaptive Battery features enabled.
It will be interesting to see the results of your test to see if my experience is true or if Google has implemented a version of adaptive Battery that actually works and gets better over time.
