Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.
+1
-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days
we really need extended battery ,hd1 battery was much more better.
Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87
I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.
I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.
try setting Network Selection to Manual

Same here with and without stock ROM.
yeah.. the phone is a battery sucker.... another cons of HD2....
This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.
I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?
maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse
I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy
Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.
I've had the HTC Aria for about four days now and my biggest issues is the battery drains to quickly. At first I attributed it to use because android phones prompt you to use them more often. However, even without use it still drains pretty rapidly. Does anyone know of a solution to this issue software wise. I have already turned off Bluetooth, GPS and Wifi. Are there other solutions
I got mine on Saturday, and I've actually gotten pretty good battery life out of it. I'm still in the habit of charging it every night, like I had to do with my old WinMo phone, but I think I could probably go two days without a charge. And that's with GPS / data always on, Wifi parts of the day, and pretty heavy use, since I'm always playing with it.
Have you tried something like Advanced Task Killer to keep apps closed that you aren't using? You can also adjust your screen brightness and timeout to try and save power.
It says that of my power is used by cellular idle or something like that 50% of it was used by that. Could it be my AT&T service
I don't get more than 10 hours out of mine. When I know I will be out all day, I turn the screen brightness almost all the way down to help conserve energy.
Good as it Gets.
With basic usage (some texting, a few calls and some market browsing or playing a game here and there) about 2 to 2.5 days without charging. Maybe the ones having issues with there phone sucking battery have to many widgets running.
In my current configuration I am only using 3 of my screens and only 3 widgets [favorites (small one), HTC clock/weather widget, and the HTC calendar widget (small)]. I have my work email checking every 30 minutes for syncing. I also have gmail and the default mail app pulling mail. I run ATK but only to kill apps on startup (cause it runs almost everything), other than that you don't need a task killer as you will have to reload these tasks next time and that will drain battery. I don't use it after that to kill anything. I am also running my screen at about 30% brightness.
Just some tips, widgets are nice, but they suck the battery life as well as constant updates. Check to see what you are running and disable/remove what is not needed or adjust sync times.
My battery life is fine. I got two days over the weekend with light usage. You need to look at what services are running and disable any widgets that you dont need. You may also want to look at the sync settings and turn off things you dont use (such as news). You do not need a task killer.
Also, see this post:

some quick tips:
1) disable market notifications - Market -> Downloads -> Notifications -> 'Don't Notify Me
2) Lower the sync times for your social network apps like twitter and facebook (or make them manual)
If you still suffer, have a look at some of the great tips HERE on the Cyanogenmod forums...ignore 1 and 3.

Also one might do *#*#4636#*#* then change phone setting from WCDMA to GSM .... Then that get little more out of battery...
It's critical that you turn off auto-sync; I have found that it absolutely destroys battery life.
Before I was losing maybe 5-10% every hour on standby, but ever since turning off auto-sync, I'm still sitting at 100% battery after 5 hours of standby.
Turning off mobile data/Wi-Fi doesn't make an impact on battery life, in my experience.

I edited your response..
Auto-Sync in itself is not going to be a problem.. Depends on what's syncing. EVERYONE will have different battery life because everyone uses their phones differently. Different configurations, different accounts used, different amounts of traffic on those accounts, not to mention actual usage patterns.

90% of people will have *slightly* different battery life.
5% of people will drain it fast.
5% will use it like a voice phone and might even get 16 hrs out of it.
But to turn off all apps makes for an invalid test because then you're testing the phone as if it were a non-smartphone, like a voice only phone.
I think the battery is too small for me and probably too small for most people. I look forward to fat batteries for this great phone.

My wife gets 2+ days out of hers... The battery is not that much smaller than my Nexus One, a more powerful phone, and I'm a power user with a lot of crap running including IMAP push mail, weather syncing... I look in at Market, Facebook, Twitter and manually sync those types of things etc.. I can easily get a full day out of it, off charger ~8am back on the charger midnight, 20-30% left. What I don't do is sit staring at my phone all day or play games for 8 hours at work, nor do I use it as a mp3 player..
This has been plaguing my phone for a few months i can't even get 24 hours without it dieing. I can't figure out what the problem is and i have tried everything except a full wipe which i want to avoid.
Before i would get about 2 days with normal usage (few calls, browsing the net, msn, music and little bit of gaming)
Now when i unplug it at 7AM it is almost dead by 3PM (15%) but nothing has changed so i can figure out where the drain is coming from. I'm using Doc 9.6.6 (was on 9.1.4 and did a NO WIPE of 9.6.6 yesterday to see if i could get better battery) and SpeedMod K13C 500.
Everything that uses data is disabled or set to manual. Wifi is disabled, GPS is disabled, Bluetooth disabled. Google/Facebook sync is disabled. No Live Wallpaper, Email is set to NEVER, Fancy Widgets is set to NEVER. Reset the battery state in recovery numerous times, wiped cache etc.
Last night phone was at 60% when i woke up the phone was at 35% and that's only about 10 hours and after a FRESH shutdown and reboot. So nothing out of the ordinary like a game was running.
Whats Running after a fresh boot is in the pictures below, ending things like Tango and Galley, Facebook make no difference.
What is causing this massive idle drain?
If i need to do a full wipe is there a way to save my games saves? don't care for anything else just dont wanna start angry birds over again for a 3rd time.
You got 2 days before??
I've always only ever gotten max 12-14 hours out of my battery. Wifi off, bluetooth off, gps off, 3g on, background data & auto-sync on for: 2 gmail accounts + facebook (no auto refresh) + twitter (updates ever 30 mins) + whatsapp. BeejiveIM, GoSMS, Lookout, weatherbug elite widget (updates every 12 hours), agenda widget, NoLED on, and go launcher ex. Running stock rom JL2. Drains about 15% overnight (7 hours).
Not sure how you got 2 days before, but sounds about right to me that you get less than 24 hours from your battery.
Myself and many others get 2 days with light-moderate usage. I'm on 2 days 9 hrs and 10% left right now with 2 hrs 15 min screen time.
If you can't figure it out you might just have to bite the bullet and wipe it to see if that works.

yes i did try that, its annoying the hell outta me that it used to last 2 days but now its like this and thats with everything off.
I used to have a live wallpaper on all the time and yes that did drain the battery allot but i would still have about 30% after a full day of usage from a full change.
Now it dose not matter what i change if i live wallpaper or not its still dies about 3PM
any way to save my games says if i have to do a wipe?
That's awesome! I get 8% an hour drain on idle with 2 gmail accounts, and a few apps synching... with usage (bluetooth music, browsing, texting...) I have about 15% an hour drain.
Wiping, battery stats wipe, new roms, kernels, and modems don't fix anything... I guess we just have to accept that some units go through more battery than others!
If you're using Google Latitude service (configured via Maps), try signing out of it and see what it does for you. I've been suffering from excessive battery drain as well and after a lot of experimenting I've found out that using Latitude on Froyo ROMs (any Froyo) leads to phone not entering sleep mode properly for some reason and therefore draining battery a lot.
Nexus S users are experiencing this as well and I've even had confirmations from Desire users experiencing this, so this might be some bigger issue not related to SGS.

There's all the standard stuff running, gmail, swype, social hub, task manager, some other widgets, etc... There's no talk time on this run, it can burn it up pretty quick probably 20+% per hour.

Wow. I'm insanely envious of your 3days! and also, your display only sucks up 53%. Something is odd with my phone, my display usually takes about 98%.

Hm, do you have Google Latitude signed in on Google Maps?
No, no Latitude.
The display will suck up 90+% if you're using the phone alot since it burns battery much faster than idle or networks.

Interesting, I'm going to give it a go without Latitude on after I reflash stock JL2. My "Time on" for Display is usually something like 40mins or so when I check it at 98%
Idle drain seems to be what are most worried about.
Ok first fix permissions from cwmedia recovery in speedmod.
Then wipe cache and dalvik partitions, don't worry your phone will rebuild them.
Next I would try something if you want avoid a factory wipe.
Disable swype and clear app data then re-enable. Swype seems to have non wipe issues thru kies.
Now use OS monitor app to find apps which lurk in the background and then check their permissions, ones that can keep the phone awake are the culprits. Wipe their data or uninstall.
Facebook app sometimes doesn't shut down properly so watch that.
Also after a session I like to use clear mem level2 to stop Facebook or another app eating battery.
Finally what modem are you using? Jpy modem sucks for me at least. The latest jve from the gingerbread leaked rom is superb!
Hope this helps and good luck!

Something I did a while ago seemed to help.
I ran down the battery till it switched off. Phone wouldn't power on. I plugged in the charger and powered on again. To my surprise the battery showed about 25%. Unplugged the charger then used it again till shutdown. Took about half an hour to do so, even though it was only connected to charger for a minute or so. Did that about 5 or more times till finally booting up with charger connected showed 0%.
Generally it not a good idea to boot with the charger connected as it stuffs up the battery stats or something, but I think in some cases it can help. Charged it to full and had no problems since.
Obviously this wont help if something in the background is killing the battery.

May be you have a task killer running in background and killing tasks that you shouldnt kill, by example any widget you have in your screen, it will cause that it will be reestarting and consuming CPU each certain time.

Remove TANGO !!! This soft was draining more than 25% overnight on my SGS (even if there's no service running and if it's not in task manager), After removing it, now my battery decreases 3-4% in 8h !
Funny Tango was the one thing that jumped out to me from the process list, but I don't have any experience with it myself. Shutting that off for a while is probably worth a shot.
This is my batterystats. "Taleanrop" is phonecalls or whatever the english term is.
It has been almost a month since I've gotten the Galaxy S2.
I literally waited like a longing puppy for almost half a year to get this into my hands.
I have to admit, it is one of the most beautiful creations to ever grace our earth, but gosh, it has this one big, big flaw... (for me) battery life. Before you dismiss this as another battery life complaining thread, hear me out...
I have tried EVERYTHING.
Ever since 2.3.3, battery drain. Then 2.3.4 was announced... NO MORE BATTERY DRAIN. The news caused a burst of elation, but it was all too brief. Flashed to 2.3.4, same deal.
I've tried all the ROMs-- Litening, Villainrom, Cognition, Infusion (now defunct).
I've tried several kernels -- the standard CF kernel, neophyte's, mirage, etc.
I've calibrated my battery after each flash.
I've tried downclocking it with SetCPU.
I've frozen so much with TitaniumBackup.
Dormancy settings, system update settings, modem roms, I've tried them all.
I even purchased, in desperation, a third party battery which claimed to have 2000mAh capacity.
All to no avail. Nada, zilch, non. NOTHING has worked for me.
Last night for example, I had charged my phone to 100%. When I woke up 7 hours later, it had fallen to 63%.
Therefore can deduce that consumption is is about 5% per hour with screen OFF.
I have also made it a point to test a different ROM/kernel for at least 3 to 5 days before I make a change.
Now I really don't know where I'm going wrong, yeah I do have a few widgets and stuff, but what is a phone like this without widgets?
I am getting so sad over this issue. This phone is so perfect in every other way.
Why? Is it just me?
One no mention of actual battery life .
Two phones get fed up with multiple roms kernels etc rammed down their throat and dont work well .

What exactly do you mean by 'battery drain' ?
Starting an new battery drain thread without even describing the type of battery drain is not a god start for this thread.
What is your idle drain? (% per hour when not using the phone).
How much "display on time" do you have when the battery is starting to be empty (no guessing, hard number from the battery menu please). A lot of people underestimates how much active use they have with SGS2.
Please also add graph for battery statistics, both the first page and also for the battery graph (press the small graph on top).
Just trying different ROM's in order to solve a battery drain issue is a bad idea, it is much better to find the root cause of the battery drain and solve that specific issue.
I mean I leave it overnight, and it falls from 100% to 60%.
It has never lasted me beyond 9 hours with mid level usage.

Apologies, my post has been updated. I don't have a good graph with my now since I'm charging, but I will post one up tomorrow.
Do widgets really make a big difference? Because that's the only thing that I have not really tested.
Could very well be a misbehaving app or widget. My phone in idle uses 0.5%-1% an hour with wifi on. Without wifi it goes slightly faster strange enough. I have some widgets that update every hour, gmail push, whatsapp and Samsung account sync.
Test without syncing and widgets and then re-enable things one by one to find the problem.
Another battery thread. That really IS depressing.
i just got my phone few days ago, battery life isn't great so far but it isn't as bad as your case.
I would recommend you do proper tests after starting fresh. flash a stale official rom, keep the phone barebones, dont install apps etc.. then test bat life with phone call usage.
Then slowly start adding and enabling things like gps, auto sync, background data and so on, till you find the cause. I think the battery life thing in the settings can help too.

I mean I leave it overnight, and it falls from 100% to 60%.
It has never lasted me beyond 9 hours with mid level usage.

40% overnight is huge, I get approx 5% in 7-8 hours.
With 5% drain per hour with no usage, haven't you tested to turn off things until the drain stops? I would start with wifi, SGS2 doesn't work well with some routers. Then just continue with the usual suspects: widgets that connects to internet etc, email sync, facebook etc. (freeze with Titanium)
Do this systematically, you could turn off several things at once, but not too many, try to find the real cause.
There is of course a possibility that your phone is broken, but that isn't my first guess.
Why does no one try Juice defender???

Oh yes, that night the 40% drain was with Wifi on, and I heard that there have been issues with the DIR-655, which I am using.
Anyway, even with wifi off, my battery life fell from 100% to 83% with a very slimmed down ROM, everything that could be frozen, frozen.

I would, but the thing is, the battery life should not even be that bad in the first place.
Sounds to me like you have a rogue app. I get 12,14 hours of heavy usage with brightness set to roughly 75%.
Don't flame him. He has tried alot things prior to posting. This is the place to post. Try the criskelo rom. It is a great rom with great battery life. Freeze wifi sharing. Delete apps at the beginning that you don't use all the time then add extra apps one by one and see what impacts the battery level the most. Check update schedules for things like news widgets and beautiful weather-I have mine set to six hours or so. There is absolutely no reason why you can't last a full day with 30-40% left.
Well, first of all, it's just a phone, although an expensive one, so no need to be stressed.
Secondly, it sounds very much like you have a faulty battery or device. Maybe you should have replaced it as soon as you noticed the problem. There's definitely something wrong there if it goes from 100% down to 60% overnight (assuming it's not heavily used during that time).
You already tried most of the things that I would do to tackle the issue. Try swapping batteries for a few days with somebody with the same handset, and see what happens.
Good luck!
For giggles, why don't you hard reset your phone? Then, instead of loading tons of apps of questionable quality, task killers, memory managers, and battery monitors, just load the stuff you need everyday. Things like e-mail and social stuff. People that haven't tortured their phones with excessive crap seem to get better battery life without even trying. With over a hundred apps, all the syncs syncing, heavy Wi-Fi use, and Exchange push I'm now up to 14-18 hours with moderate to heavy use. If the experiment works, start loading the rest of your stuff on your phone to see what the impact is.
Another thing to consider is your network connectivity. Your carriers signal strength and infrastructure could be part of the problem. Certain carriers and locations seem to contribute a lot to batter drain. Also, the SGS2 is very router sensitive. It likes Netgear, D-Link not so much.
Good luck.
This is with a screen on time of 2:14 too, and overclocking to 1.52gHz
There is no battery issue, this phone has twice the battery life of the desire hd and thats a fact, i have not changed fast dormancy or anything, this phone is king for battery life.
Played games and browsed internet, i would say medium heavy usage
Using 2.3.3 KF3
Also if you had a laptop that lasted 10 hours with 63 remaining wouldnt you think that was good? This phone is the absolute top dog, i would even say its better than IP4 for battery now
Also used cardiotrainer to track my run this morning using GPS, ran for 30 mins and lost around 6 percent... Amazing!

A lot do but informed opinion is that it drains battery .

Yep Juice defender sucks, and is not needed really...
You either have a rouge app sucking the life out of your phone,
Your syncing at too short periods (mine is set to 1 hour)
Your phone signal is weak so your phone is using more battery drawing 3g from your service provider
My Essential PH 1 is draining a lot.
Phone idle is taking most power with approximately 17%. Screenshots attached.
Can you please advise if this is normal and ways to minimize battery drain ?

Are you showing off? because those are amazing numbers. You're on track for 35 hours! I get around 26. Your bigger killer is What's App, but that's expected for a Facebook app. 17% for idle means your phone is on and doing nothing 17% of the time.

Nope I am not showing off, I think i am having huge drains when I am asleep. Most of the time in that graph is idle time so i am thinking it should be better ?
Again I moved recently to droid from iOS so i am unsure of the droid power management baselines.

Cool. I didn't mean to seem mean, but those are good numbers. If your phone is on, and you have push notifications (pretty much every social media app, phone, sms, etc.) you're going to have drain. Even if the phone was off, the battery would drain somewhat. But you have What's App and other chat apps, so that'll use battery, even if your asleep, the phone isn't. It's the only way you would be able to receive calls, text, updates, etc.
That 17% looks steep, but it's all relative to a small screen. over the span of 20 hours and you still have almost 50% battery, especially with "free" apps that are basically advertising engines pushing ads at your every minute. Having Phone Idle at the top is not a bad thing, it just means you don't use your phone as much as you use What's App.
1% per hour is good, better than our S8 even
I had enabled "Cellular data always active" and it chewed through my battery life. I turned it off and can now last 1.5 days on a charge.
My phone is draining 12% overnight. And phone idle is top of the list. What does this phone idle do? There was a random night where the phone only dropped 1%. But most nights, it's draining around 10% with phone idle at the top.
Update: setting wifi to not stay on while phone is sleeping seems to fix the drain issue.

Does disabling it affect receiving messages that rely on mobile data such as WhatsApp?
Where is the "cellular data always active" setting? I don't see it. Have not updated to run Oreo.
My battery was dropping from 95% to 5% overnight. Did a factory reset which helped, but I'm still losing 17-20% overnight. Seems odd to me on a brand new phone, but I have never owned an Android before. I have blocked notifications and location services from nearly all of my apps. Any advice other than what has already been posted?
If your losing that much overnight it's probably a bad app.
I don't use it, but have read that the Facebook messenger is good for that. As in eating up a battery overnight.

I can promise you that that's not normal, especially for this phone. Overnight battery loss is minimal, 15 hours of idle with a 10% drain is what I'm getting. That's pretty amazing. I'd check your apps and ask the general android forums for advice. I also bet there is a rogue app draining you juice. chat and social media apps with all their pushed content and friend updates are huge battery killers.
Install accu battery ,charger to full last thing at night ,don't touch through night ,then see what's draining battery ,mine drains by about 2/3% through 8/9 hrs at night

It's under developer options settings. I have mine always active without draining my battery noticeable.
The social media apps such as snapchat, facebook, twitter, etc... are the ones draining your battery while your phone is idle so you need to disable their background data running.

The option to Cellular Data Always Active is on the Developer Hidden Menu. If you have it enabled you should be able to turn it off.
Thanks to all for the replies. I thought that restoring factory settings had helped somewhat, but it turns out not to have. Battery has just depleted from 100% to 67% in 3 hours while the phone has sat idle.
The only social media apps I have installed are FB and Whatapp. Notifications for both are turned off. Location services for all apps are also off. The only apps I have installed have been download from the Play Store and have run on my previous phones without causing any trouble. Those who replied all suspect a bad app, so I have installed ACCU Battery as suggested to see if I can nail it down.
Thanks again for the responses.
Try this for one night. Right before bed....
1. Turn OFF WiFi
2. Reboot phone
3. Leave WiFi off after reboot
There is a bug in Google Play Services that affects many people on many different phone types since the November updates.
When on wifi, in certain circumstances (many theories on what the actually trigger is) it will cause Google Play Services to run non stop on certain WiFi networks causing huge battery drain.
In this particular scenario, turning off Wifi does not stop the battery drain. The phone has to be reboot.
I don't know if that is what you are experiencing, as you didn't say if it was an app or system taking so much battery, but I thought I would mention it in case it helps.

Why don't you look in settings/battery and see what is using the highest percentage of the battery?
Have looked in Settings/Battery, but am not seeing anything there that diagnoses the problem to my understanding. Highest use shown is Chrome (4%), then Screen (4%) then Google Play services (3%). ACCU Battery app shows the same. Battery is still losing 10-12% of its charge per hour while the phone is idle.
Have sent a message to Essential support to ask if they know anything about a bug in Google Play services causing battery drain. They have so far only suggested rebooting to safe mode and doing the reset to factory settings. Hasn't helped.
Will try shutting wifi off, rebooting and leaving wifi off tonight as suggested. Not really sure where to go from there even if that does save the battery, as a phone that has its battery drained just by being on wifi is useless to me.
If turning off WiFi and rebooting helps reduce system cpu usage, it is a bug in the software and not the phone. I can reproduce that specific issue on my pixel 2 and Samsung Galaxy s8, too....
If the CPU usage isn't from system, though, or turning WiFi off and rebooting doesn't help then you obviously have a completely different issue and need to troubleshoot further.

Update:. Nothing Essential support has suggested has helped. Battery is draining to zero overnight while phone is idle both when connected to wifi and when not.
Upon learning that I had purchased the phone at a Telus store in Canada, Essential have said that they can't help me further and have referred me to the store for assistance. I'm disappointed in the lack of support from Essential.
