I've just done some undervolting and governor changes on my phone... (faux 012 kernel), build.prop added ro.ril.disable.power.collapse=0, pm.sleep_mode=1
On Powersave (where the CPU frequency is locked at the lowest 192mhz, I was able to hit 9mAh(reported by Battery Monitor Widget with HTC Sensation current detection option enabled) on idle with data on, sync on
Reported by the phone's built in stats:
30 min screen-on time, 1 hour phone on time, >12 hours deep sleep, my battery was just above 50%
of course, with frequency at 192mhz, there was major noticeable lag... one time, there was too much stuff running on the phone when it rang, and it couldn't work fast enough for me to answer the phone in time before bouncing to voicemail
lowest noted current usage before change - after change
deep sleep: 20mA | 9mA
screen on idle: 100mA | 60mA
9 hours usage before hitting 50% | >12 hours usage before hitting 50%
I've looked/used at the other available governors....
the interactive is next "power saving" efficient... clocks up from 192mhz somewhat slowly after some use, and goes back to 192mhz
the conservative is next... clocks up very fast from 192mhz use, slowly goes back to 192mhz
the ondemand clocks up faster and goes down slower
all of them clock up from 192mhz when the usage barely passes 50%
anyways... is there a way to customize my own needs? I want the phone on 192mhz until the CPU goes over 90% for 1s, then clocks up slowly... when a phone call comes in, i want it to use as much as it needs... etc
Maybe it's just me, but this phone is pretty fast/stable without missing with out volting

I just want to be able to maximize battery life when I need(eg when I'm going out and I know I won't be near a phone charger for more than 20 hours, and still need the use of GPS/camera etc)

There are several other things you can do which may be more effective than what you are trying to do- or even more effective WITH what you are trying to do.
First, don't lower the minimum clock speed, 384 is the minimum that HTC chose, probably for multiple reasons. As long as your phone is going into deep sleep, it doesn't use ANY processor, and on any governor EXCEPT battery saver, it is VERY rarely idling at the minimum speed.
Next, look at the init.post_boot.sh and init.qcom.post_boot.sh files(you may have one, or you may have both, faux added the second one in later builds) in the system/etc folder, that sets many of the kernel settings. Do some research into how changing the line for "down_differential"(which is 5 stock, 1 increases battery A LOT, but increases lag a bit too), , "up_threshold"(stock is 90, setting to 95 increases battery, but takes longer to get to full clock speed), "sampling_down_factor"(stock is 4, you can lower to 1 for increased battery life, and slightly more lag), "sampling_rate"(latest faux changes to 30000, setting to 50000 means it checks whether to increase/decrease cpu speed less often, and gives better battery life).. changing those values will have much bigger impact on battery life, while adding a little bit of lag at most if you change them quite a bit. Also, look to see if you have a line that says "echo 1 > /sys/devices/system/cpu/cpu1/online", if you do, change it to a 0, 1 forces the second core on ALL the time instead of letting ICS decide when to turn it on.
Next, look at thermald.conf in the same folder, some of the biggest differences in battery life between roms is because of that file- faux replaces it with his later kernels, but I'm not sure if it is to increase battery life, or increase performance. His is definitely different than any rom I have seen, and people report much improved battery, and that file is likely why.
Doing all of these things with system files rather than with a 3rd party CPU app means the phone will deep sleep more, and be more responsive, because there is no app constantly running in the background trying to make changes on the fly. Also, you can find "battery saver" scripts that can be put into the above files that have their own tweaks you can make if you are determined to use that governor- but battery saver tries to constantly stay at the minimum speed possible(if you read it in some places, it simply stays at minimum speed PERIOD), and will have the most extreme lag, with a questionable amount of increased battery life compared to a tweaked on_demand governor.
And last, before undervolting, try decreasing the max speed of the core.. you can lower it by 1-2 steps and notice NO difference in speeds, yet get far better gains than undervolting, without creating instability. The volts that HTC chose are probably the very minimum that works well for all of our phones, as undervolting by 12.5 may work fine on my phone, but may introduce random reboots or worse on yours- once you undervolt you simply can't troubleshoot any issue on your phone, because the UV could be the cause instead of anything else..
There is more than that you can do also, like making sure that your screen-on and your actual usage numbers are almost EXACTLY the same- get an app like betterbatterystats(available free on XDA) to see what partial-wakelocks are keeping your phone from deep-sleep.. the higher the % of deep sleep, the less you have to worry about ANYTHING to do with the CPU, since the CPU isn't being used at all..

If you do everything I said above to maximize battery on the on_demand governor, you can use a CPU app to change to battery saver governor when you know you won't be near a charger, and you just want basic functionality(no games, browser, etc), and DONT set on boot.. that way on reboot it defaults to normal governor.
I tweaked all the things I said above and get at LEAST 16+ hours with 3+ hours of screen on, and will get over 24 hours if I underclock to around 1.2ghz.. battery saver isn't even needed if you set everything else right.
Or you can buy 2 1900mah ankers and an external charger for 29.99 and free shipping on amazon, and simply carry the spare charged battery, and never care again.. much simpler fix if you ask me.
thanks for the tips Silentbtdeadly. I'll look at them this weekend
I am already using the Anker 1900mAh battery, with the latest faux kernel and energy stock ICS rom...
I get maybe 15 hours from 100% to 10% with ~1-2 hours of usage
From looking at BetterBatteryStats, it looks like the phone is falling into deep sleep properly with no obvious problems with wakelocks/alarms...
If I left my phone unplugged overnight with data on and autosync, it levels out.... lost 9% over 6 hours
I think I just have 2 main problems:
Drain from 100%->80% is fast after unplug... I think it takes 30 minutes to get to 90% and another 60 minutes to get to 80%. BBS shows phone in deep sleep, Battery Monitor Widget shows mA usage ~50mAh with -2%/hour, but the %-left slopes down a lot, since i did lose 20% in 90 minutes
when I turn on the phone and use it for <1 minute and put it back to sleep... Battery Monitor Widget shows a sharp drop in %-left even though BBS shows falling into deep sleep
I guess my problem might be the battery-monitoring hardware/firmware... I just received the Digital Timer, will try Bump Charging to see if I can get 16-20 hours with 3 hours of usage

Careful with battery monitor widget, the way it polls the battery creates its own drain.. there is another widget called currentwidget that can actually log how much energy is being used by an app, it too can drain a lot, but it could show you if a certain app is using an absurd amount of power.. I have more info for it in the battery saver section of the bible in my signature.
I think about 16 hours with 2-4 hours of screen on is the most that can be gotten without seriously degrading the performance. If you set the governor options like I said in the last post and under clock a little, you will get a little lag on minor things, but the phone is still quite usable, and 24 hours is totally doable at those settings with 3-4 hours screen on.
Do realize the anker batteries aren't perfect, I bought two at once.. one gives me much more battery life than the other does even tho they were bought together, so that could be a factor too. I try to maximize battery life, but I'll carry a spare charged battery so I don't worry too much, it is the best solution thus far.

Hey, so I've seen several people claiming fantastic battery life, etc. So, I am just wondering what's your experience in general. If you've got some free time and feel like typing, can you list several things like:
roms & kernel
stock/anker battery
battery life
screen time (and possibly voice call time or whatever else that seems to consume lots of the battery life)
highest battery temperature (I recently got pretty high so I was kind of worried)
and anything else you think might worth sharing (favorite actress? :silly
As for me, I recently installed Speed ROM 6.5 with stock kernel on stock battery
I only got 8 hours battery life to get to 14% with 3 hours of screen time (mostly used for game, browsing, and flipboard)
I got up to 100F (~40.5C) after playing a game for about 15-20 mins which made me leave it for a few mins to cool down. The next time I played the game again, it got up to 109F (~43.5C) after playing for 20-30 mins....
I am wondering whether that kind of high temperature is normal or not, and whether my battery life seems ok or bad; which is why I am hoping people can share their experience here. I haven't try using faux kernel though (might try it tomorrow in hope for a better batter life)....
So, again... if anyone got free time and feel like typing, please share it with me :angel:
From my g2 to this phone all I ever see is how bad the battery is. Never noticed a difference switching roms and battery across all smartphones I've used is allot what I expect.
Some people just can't be happy you know. Not to mention people never agree on anything (me included ).
Just my two cents

Well, first off, I am not trying to complain about the phone here. All I am asking/trying to find out is whether my experience is "normal" or not for Amaze.
I also come from G2 and obviously the battery life will be worse on the Amaze in general. This phone is 1.5ghz dual core and 4.3" display compared to 800mhz single core and 3.7" display on g2 with only extra ~300mah on the amaze.
I just want to know if my experience of getting only 8 hours battery life (with 3 hours of screen time consist of game and browsing) and getting a high temperature of 109F on the battery is considered "normal" or not for this particular phone. I only have one phone here; so, I don't know if my unit is bad unit or if it is normal for the Amaze.
So again, by all means, I am not trying to complain about this amazing phone here. I am just trying to find out if this is what normally happen with this phone.
And yeah I'm one of those guys that can never be happy :silly:. When I used G2, I want larger phone and faster performance. When I got Amaze, I want slightly larger screen and much better battery performance. So, yeah I can never be happy with my phone :laugh:
The temperature thing is definately normal, it can get pretty high. I've had it go above 109f while on video chats on Skype. As for thebattery, that's normal too its just dependent on the user. U may have something that's running continuously in the background that your not aware of that's causing drainage. Many things that could be effecting the battery really

@OP, most likely you either have a bad battery, or your phone isn't sleeping properly on idle, or your phone has some problems with the RUU
Code:
Battery is ~1900mAh. If you use it for 3 hours active at around 400mAh, that is 1200mAh
700mAh left for idling the rest of the 5 hours. My idle current usage is around 9-40mAh as reported by Battery Monitor Widget(go to settings, change monitoring mAh to HTC Sensation to get a better reading)
700/5 = 120mAh/hour.... this means your phone isn't sleeping properly
Get CPU Spy... install it, then put your phone down for an hour without using it.... after that, does the report show that it goes to deep sleep?
When I got my phone and flashed the ENERGY rom, I had ~8 hours of total uptime (1-2 hours of usage)... i reflashed the RUU (do it on 100% battery), then it is better now
Now, on the Energy STOCK ICS rom with FAUX latest(0.12?)
Anker battery
15 hours of uptime
1-2 hours of screen-on time(roughly 2-3 hours of phone "awake" time)
don't remember battery temps, but i don't ever remember ti being that high
interactive governor, max frequency 1.4 ghz(to maximize battery life)
data on, autosync on, 2 gmail accounts synced only
My 100%->80% battery drains in 90 minutes, but after that, it slows down
I added the following to build.prop to tweak more battery life
Code:
# Power Save Tweaks
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
If you really want to stretch out the battery, change the governor to powersave(forces processor to 192mhz always), but it definitely lags and I wouldn't recommend it unless you really really need to max battery life
EDIT: Go to Settings->power->see what is using my battery, post a screenshot (this one is 16 hours plus ~2 hours usage)
see the part that says "awake", and the part that says "screen on"? It should be correlate mostly -> when you use your phone's screen, the phone is awake.... when you turn off the screen, the device should be sleeping and not be awake

I guess this phone is just that "hot" eh....
So, you're saying that I should be able to get a better battery life than that?
By the way, did you use Juice Defender or anything like that? Or did you just let your mobile network and wifi on all the time?

Hmm... I would try to check the stuff that you said. I did see the battery use like you did and I have much more awake (since I used it for games and browsing continuosly). But, when I was not using it, it doesn't show that many "awake" status which is why I thought that Amaze battery performance is just that poor. I forgot to try third party app like battery current widget or cpu spy. I will check those out.
Did you use Juice defender or anything like that? Or, did you just set them manually when you need it?
And I did leave my WiFi and auto sync on.... From your usage, I'd assume you turn off your WiFi when you're not using it, right?
Thanks for the input
Edit: So, I am guessing there's a rogue app on my phone? I just reboot my phone, leave it for a minute, and battery current widget shows 200mA on my notification bar
From what I'm reading your a heavy user. Like me lol. The most I get is 6-8 hrs. With 1.5-2 hrs screen on time. Comparing that with others who get double digits It's nothing but I'm a heavy user. I stream Pandora daily surf the internet for 1 hr non stop, xda for most of the time. . And on weekends I'll have most 4 hrs. But 3.5 of those screen on with data streaming and screen on with out going off. Kinda like watching a netflix movie on mobile network. I use my phone like if it is my laptop now. I rarely use my laptop. I don't have internet nor WiFi to connect to. But if I tether I would run out of data faster so I avoid it. Besides battery draining faster.
I think there is a difference between:
1. leaving the screen on for a while, causing the phone and battery to get hot. Specially when gaming because CPU is constantly running.
2. And total screen on time accumulated of 2-4 hrs screen on. Which is achieved when sporadically checking phone for text, calls, email, quick surfing. Then shutting of screen through out the day.CPU goes to deep sleep phone stays cool.
Now that's what I call a heavy user.
Remember when phone is hot battery drains faster so you need to find a way to cool it down. Sometimes there are settings in cpu apps that when phone reaches certain temperature that app will force cpu clock down a lot as to use less power to start cooling down but causing lag.
I've got a 4 month old stock battery with latest faux kernel v.16 with battery saving tweaks on it. Energy rom stock 8-1. If there is anybody that reaches double digits with 6-7 hours 4g mobile streaming not wifi at all. 2 hrs without turning the screen off not 2 total hours. Please say I? I'd really like to know your secret.

Battery Current Widget... go to the options (top right), change the current selection(should be first row, then middle row) to "HTC Sensation" (it'll be more accurate)
that program doesn't accurately report mA if you don't change it(before changing, it'll be screen-off deep sleep 100mAh, but after switching, 10-40mAh)
I don't have Juice Defender on... autosync and data is on all the time
try w/o wifi on... i think wifi should take less battery power than data, but it always depends
on my screenshot, if you go back one and click on the screen-on... what does it say?
what does CPU Spy say about your phone going to deep sleep?

if you are only getting 8 hours uptime with 1-2 hours of usage, then your phone's not going to sleep properly... I'd reflash the RUU, then flash Energy ROM and faux kernel... i had that problem before I reflashed RUU (but that was before I knew more about CPU states and mAh usage on this phone, so I don't know if it was a problem with the deep sleep, or the phone not properly updated to ICS when I got it from someone else)
you want to try to max battery life? I can give you hints to hit that mark... it's all about physics/electronics
your battery is 1900mAh.... Using Battery Monitor Widget(with the Settings changed to detect the phone as "HTC Sensation", see above)
With the tweaks in my first post of the build.prop, BMW shows my idle around 10-40mAh..... 10 hours of idle = 100-400mAh. Note, this is with sync and data on... if you use Juice Defender or data off, probably less
So, idle, you use up 400mAh... you have 1500mAh left
1500mAh / 6 hours = 250mAh each hour.... with BWM, it shows that the current usage goes between 100-500mAh depending on how much screen brightness, data used, processor speed... If i choose powersave, I think it goes between 50-300mAh, but its really laggy, noticeable
300mAh * 6 hours = 1800... close enough
to avoid the 100%->90% fast drain, employ bump charging:
either
1) charge your phone to 100%. remove plug, wait for it to drop to 90%. replug it, charge to 100%... repeat for 5-10 times
2) charge your phone to 100%. remove plug, shutdown. Replug it, wait till the light goes green, boot up, charge to 100%, remove plug and shutdown, replug it , wait till light goes green etc.... do the cycle for 5-10 times
I was trying to see how much I could get out of my phone. I used my phone as little as I could, putting it into airplane mode when I slept.
ROM and Kernel: I was using the latest build of Energy and Faux Kernel v.15 at the time of the picture
Using stock battery, unfortunately I do not know what the highest battery temperature is.

unfortunately, for this device, the screen brightness and dual-cpu takes up a lot of power... if you see the pic below, when you use your phone(screen-on/awake), the battery % left has a sharp drop
I know for my old phone, LG Optimus T, I didn't have a data plan... the phone had data off all the time, and I got days out of using it(phone calls, wifi/browsing, checking gmaps offline)... once I enabled a data plan, it got half (like 1.5 days instead of 4)
if you calculate your usage... its possible
24 hours * 50mAh during idle = 1200 mAh
2 hours * 300mAh/hour during screen-on usage = 600mAh
total = 1800mAh, the capacity of your battery

So if I use either of those 2 methods above, is my battery 'cured" of the 100% to 90% fast drain? Or do I have to keep doing it over a period of time?

bump charging only helps you for that one time... you have to do this every time if you want max battery capacity
the problem is 2 things
1) the hardware/software is configured to maximize battery lifespan, meaning to slowly charge it and not go to 100% (high voltage, damages battery)...
2) the hardware/software is poorly coded, can't read the battery voltage properly...
either way, doing this means you are forcing current into the battery every time... your battery will hold less charge in a few months if you force it to full everytime... so you have to get a new battery aftera couple of months or live with lower capacity
I will just try to observe it better tomorrow using all those apps. With much less usage (1.5 hrs of screen time), i only got 11hrs of battery life. The screenshot below is for those 1.5hrs f screen time... I dont use jd and got email sync every 1 or 2 hr though....
Sent from my HTC_Amaze_4G using xda app-developers app
I tested the idle-deep sleep capacity of the phone...
got 21 hours idle, 17 minutes screen-on (minimal use of phone) with 50% left
here is my phone with data and auto-sync ON, I got roughly 10 emails(all received during different times), had about 10 minutes of phone calls
NOTE: around the first part of the graph, you see the %-left spike up... I rebooted my phone then... and you can see that the battery-monitoring software/hardware part recalibrates itself to the real value
NOTE: cell standby-time of 21 hours used more battery than screen-on of 17 minutes.
When I used the phone for another 15 minutes, screen used 35% of battery while cellular standby dropped to 22%
tl;dr, using the phone, especially the screen, kills the battery a lot more... not using the phone = lasts a long time

I guess after using all those apps that you mention, I can kind of see that Amaze battery is just way worse than my G2. I was pampered with my G2 battery life for a week and now I realized how bad Amaze battery is. lol
I got 11% left after 12h 15min. That's about 1550mA used (I use stock battery).
almost 3 hours of screen time (3*350) = about 1050mA
25 mins of phone call = ~120 mA
about 8h 45 mins of idle = 360mA
So, yeah, it summed up about right this time (more accurate compared to my first result where I think I got a rogue app)...
**I am eagerly patiently excitedly waiting for a fully working stable CM9 by sport :angel: **
On a side note, just wondering if anyone know if galaxy s2 have better, worse, or about same battery life? I am just curious since s2 is supposed to be amaze rival at t-mob....
Here's mine
Rom: Fourth Bar Jellybean Fusion
Kernel: Faux's Kernel, latest edition [August 15th]
Average Temp: high 90's
Average Battery Life: 5-6 hours.
Realize that what you do with screen on makes a significant difference- If I play organ trail(awesome zombie game styled after old school oregon trail game) I can play for a long time with little battery drain.. but it is a 2d game, and not going to be very processor intensive. If I play final fantasy 3, a 3d game, wow.. battery will drain much quicker, but then again, it IS a 3d game, and processor intensive. So HOW you use your phone is even more important than the screen on time.
With the latest faux(17) kernel, and 2-3 hours of screen on, the last few days I have 45% battery left after 15 hours since unplugged. Maybe 30-45 minutes was organ trail, but not much other gaming. The only changes I made, were made to the kernel, which I posted here(be aware that making all those changes will create some small lag changing screen orientation or opening app drawer, but haven't noticed anything else). http://forum.xda-developers.com/showpost.php?p=30298629&postcount=4
I also underclock to 1.2ghz- this doesn't create any lag, and no game or app I have used seems to work ANY better @1.5ghz than it does @1.2ghz. The main difference is the voltage it uses at max speed will be less @1.2ghz.
If you have weak 4g signal, there is an app i recently posted in some thread that puts it on 2g while screen off.. that has helped a lot too. If you have constantly good signal, then it won't make MUCH difference(tho 2g does drain less than 4g even with good signal), but it takes up to 2 seconds for it to switch to 4g after screen on. I can wait two seconds before opening an app, I don't care.
I assume you have used betterbatterystats to see what apps keep your phone from deep sleep, under partial wakelock?
And when I get obnoxious drain, but NOT because the phone isn't going into deep sleep.. I turn on the logging of an app called currentwidget- it can actually measure the MAH used while using specific apps.. the app itself can cause a bit of drain, but you'd only use it long enough to see what app is so battery inefficient. I have more about how to use that under battery savings part of the bible in my signature.
Edit: And I consistently get battery temperature of 77.7-77.9F, I always have, no matter the kernel or rom or settings.. perhaps it raises a TINY bit when I play some intensive game, but never noticeable. I am using an anker battery tho, so if you are using stock, perhaps that is a factor.

Good to know that. I used a different app to check the current mah and it seems reasonable. I forgot to use better battery stat; but, based on cpu spy, the deep sleep time seems about right... I haven't updated my kernel to v17 (still on v15) and haven't done any edit that you mention since I was still switching roms to find the ROM that suits my need. I might try to do those stuffs today and hope for the best.
And btw, I am kinda jealous with your battery life... 45% left after 15 hours unplugged and 3 hours screen ON
I might get similar result; but my battery left will be 10% and those screen on are mostly on flipboard, xda, and browsing....
Like right now, 6h 10min unplugged, 40 mins of screen on (xda & flipboard), and I am down to 66% :crying:
**On a side note, I just get my hand on gs2 and I am just curious to try and see how good it is since gs2 seems to be such a hyped up device compared to amaze.... :laugh:

Just checked my usage. I'm sorta similar to yours in terms of screen on time. 11 h 43 m since unplugged, 39 min screen on (facebook, news, texts) and I'm down to 62%. My screen on time isnt that high, yet something else is draining my battery.
Awake time is 1 h 44m. Lots of Alarm Manager partial wakelocks. need to figure out what's causing those
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 Google Pixel 4 before depleting the battery.
Then, drop a comment if you have anything to add!
Getting an Average of 4.5-5.5 SOT.
Same as my SD855 S10
3 hours SOT here. 12 hour batter. Buyers beware.
I read a review saying if it didn't have such poor battery life it would be one of the best phones, though it is that bad it really holds the phone back.
Sent from my [device_name] using XDA-Developers Legacy app
Same as Pixel 3 and pretty much any other my phone in last few years - about 4h-5h of SOT every charge. Nothing drastic.
Usage pattern per day:
1. ~2h spotify BT stream (in car and to sony wh1000xm3);
2. Never on wifi;
3. Location/BT always ON;
4. 30-60min of youtube;
5. Whatsapp, spotify, youtube, waze, chrome.
Better battery than my S8. Around 4h-5h of SOT along with 26hrs of standby time on first charge. I am happy with the standby drain which was pretty bad with S8.
Usage pattern:
Motion sense off.
Tap to wake/Lift to wake on
Location always on.
Bluetooth for 3-4hours with Spotify streaming.
Whatsapp, Youtube, Facebook, Chrome all in the mix a bit.

yeaaaah...these battery horror stories on pixel 4/4xl are most definatelly overexaggerated. It always depends on the usage, but at least from my expierence and how I use phones almost every phone in last 3-4y gives me my 4-5h of sot..either its xiaomi 9t pro, oneplus 3-5, iphone x, xs max, pixel 2-3, galaxy s9+, its always the same..only phone I have gotten out more is my test phone Iphone 11 Pro .. that phone battery wise is simply amazing! probably the most I have gotten out of phone measuring one week+ of usage with 5-6 full charges, but I couldnt make it my daily driver since I find IOS just too boring + i really disliked the weight of iphone 11 pro in terms how it feels in hand (top part is disproportionally heavy) and limited in few key areas like quickly sharing stuff and so on..just not for me..IOS is ok for me only on tablets (ipad pro 11")
I started with Nexus 4, 5, 6P, Pixel, Pixel 2, Pixel 3 and now Pixel 4. Each iteration of phone provided improved battery life due to better software and better hardware. I was also worried about the battery life of Pixel 4 after reading so many articles about having a smaller battery. I am telling you this. All these articles were based on speculations, none were based on actual usages. I've never complaint about short SOT but always wished that standby drain can be controlled better and I'll explain. If you run a test of SOT when the battery is fully charged, you may get let's say 5 hours out of it but that is not meaningful. On real life usage you'll carry the phone with you 10 to 14 hours a day. While SOT usage varies between person to person, most of the battery were drained while the screen is off. Let's do a simple math here. If you can get 5 hours of SOT out of 100%, that means your phone consumes 20% per hour. On average my Pixel 3 was draining about 2% to 3% an hour with the screen off. In 10 hours I am down to about 75% which would provide 3 to 4 hours of screen time. With the Pixel 4, the standby drain is much better controlled, a big step over improvements over previous generations. I figure the standby drain is about 1% to 2%. In 10 hours I'm down to 85%. Even if the SOT is identical to Pixel 3, I will get at least half an hour more screen on time during real life usage.

Totally agree with your theory on standby drain. I carry two phones, one for personal use and one for work (iPhone). I'm always confident at leaving iPhone unplugged overnight but not for the Pixel. It barely drains 1% on the iPhone overnight. I wish one day we could see this on Android...
btw Pixel drains 10% to 20% overnight depending on its mood
Strange, mine drains 1-2% overnight

the drain is adaptive battery, Bluetooth and wifi scanning. turn those off, once you do, your Google Play services battery usage will be a lot lower.

Both BT and WIFI scanning are off. But adaptive battery is on. I thought it's meant to reduce the battery usage instead of drain the battery?

turn it off and tell me how much better your battery is tomorrow. and if you want performance the way the pixel 4 and 3 were supposed to be, turn off digital wellbeing. it's better to delete it through adb, but just turn off usage access to try, restart your phone and be amazed.

everybody uses their phones differently brotha. you should show a screenshot of your battery stats. if you have bad reception, there's no cure for that.
Mine drains 1-2% over night in a 8 hour period
