Normal to discharge while screen off? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Seems to be losing 3-4% an hour with phone on screen off..
Is this normal? just sitting idle without touching it..

That's sounds about right...some ppl are reporting on averages its about 10% of battery life per hour. On the stock Rom. Go and check out the battery life thread

No, that's not right. You have an app eating your battery, with your screen off you should average 1% every 2 hours, 1% ever hour, MAX. Unless you have WIFI doing something crazy or a terrible terrible reception you should have really decent idle life.
With 1 bar of LTE here (constantly switches itself between 1 LTE and 3 bars of 4G where I live) I can have a battery last 9-10 hours of relatively heavy usage (calls, texts, browsing, games, downloading, etc.). I flashed Da G's .3 kernel and it increased my battery life drastically.
I still have something eating battery under Android System, it shouldn't be THAT high, IMO.

Here is my screen shot.. something is strange.. have these broken lines...
Have frozen Noled as of now..
Seem odd?
* I think Noled was the culprit.. will charge to 100% and wipe battery stats and drain and check again..
Seems it was keeping phone "awake" at all time with Noled..

Noled was the problem.. its gone.. Rocket is back in action again.. 5 hours and 96% left
If anybody is using Noled.. be careful with it.. if you are experiencing high battery drains.. look there first!

The ROM I'm using (TPC v3) for some reason won't put the phone into deep sleep when wifi is on, so I have to turn off wifi AND mobile data (leaving that on is like leaving wifi on, it's LTE) to get it to go into deep sleep.
I should flash a new ROM and see what happens.

battery life

anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.
See my post here:

Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.
I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.
Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.
Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.

I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.
I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.
I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.
My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.
I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.
I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.
heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life
Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.
It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu

GummyCharged and battery Drain Issue

I know this has been discussed in the Gummycharge thread, but its buried pretty deep.
I know kej said that it has to do with the gallery, but I have uninstalled the Gallery3D.apk using the toolbox and I still seem to be losing about 10% per hour with the phone sitting idle on my desk.
Is there something we can use to quantify the appropriate battery drain rate? We all use our phones differently, so we need a way to standardize the battery drain so we can discuss it.
I saw someone mentioned that they were only losing 2% per hour while idle.
Currently, If i unplug the phone, and leave it sit for an hour (after a full charge) with only wifi on (gps, and bluetooth off) I lose about 10% per hour. If i use the phone at all, for example, When i wake up in the morning after a full charge and read the latest XDA posts, or some news articles, I can go from 100% to 85% in about 20 min.
this doesnt seem right.
Can we consolidate the battery drain issue to this post and post fixes and discuss reasons here?
This should have been posted in General first off.
Also, do you have SpareParts installed? If so, use that to check if your phone is entering sleep mode. You may have an app that is preventing your phone from sleeping, which will cause excessive battery drain like you are experiencing. My battery drain is <<1%/hr in airplane mode (I lose 1-2% over 8-9hrs in airplane mode) and when not in airplane mode, I'd say I loose at most 2-3%/hr if the phone is only sitting idle and I'm not using it.

Ive looked in spare parts and Im not sure where it would give that information, under battery history ive got running at 38.2%, screen on 25.2% phone on 14.5% and wifi on 100%
nothing mentions sleep mode

I get a drain of about 3-4% an hour if mine sits. However I leave it on LTE and at the office there is no LTE service yet. Yeah I'm just lazy......lol.
Curious on your SpareParts thing tho. I've never used it much really. Where does it show/display whether or not it is going into sleep mode. now I'm kinda curiosu if mine is correctly or not. Not that I'm very concerned about 4% and hr as I make it threw a full day fine. TIA

If it's not running, it's sleeping. You're battery drain is likely caused by wifi being one 100%. If you are leaving the cell radio on, LTE, and also wifi, that is 3 radios on all at once, draining power.

is that just an issue with the charge? with my Incredible, leaving wifi on saved battery as it did not need to talk to the cell tower and try to get a 3g signal. Also, Before I flashed, I was able to sit all day in school and still be at %80ish power.
I will see what turning wifi off does.. but to be perfectly honest. that seems a little inefficient, that would mean every time i turn on the phone to use it, i would have to turn on wifi and sync, then turn it back off again.
For example, since I wrote this post, my battery has gone from 87% to 70%. 17% in 66 min even with wifi on, that cant be "normal drain". And All i have done is looked at 2 text messages.
Please do not get me wrong, I am not complaining at all. but I would like to get to the bottom of this.
I was on my way to the store to return the charge I hated it so much, but after flashing gummy and your kernel, I love the thing more than any phone ive ever had. So please do not mis-judge my intentions here. I simply want to know if this is normal. In my experience with sell phones (Droid Incredible for over a year, Wife has htc thunderbolt, and now the charge both stock and now custom rom) It is draining much much faster than any phone I have used before.
If this is normal, then I will just deal with it.
I am going to put it in airplane mode for the next hour and see what happens
It is def something in connectivity. Still at 75% after 1 hour in airplane mode. going go turn on 3g only and check again in 30 min.
I was going through battery stats and saw that wifi ON was at 100% and Wifi running was also at 100%..
seems like maybe somethign is using my data. so if that is true, it should try while on 3g and I should get huge battery drain.
will report back
Dude you are NOT alone. my phone drains like a siv, when its nt even being used. I always have LTE off, unless i tether wifi and I always plug it in when i tether so i dont drain. Itll just sit and be idle with NO use and lose 30%. i have gps, wifi and bluetooth off..... wth? this phone is looking ro get returned if i cant sort it out. i cant sit on a charger all the time.
If you are running Gummy, the gallery thing should not be an issue anymore (he fixed it a few versions ago).
When you go into spare parts, go to battery history and change to sensor usage. That will tell you immediately if you have some app that is draining your battery (ie the Gallery).
For the most part the battery killer for people is network searching. 3G,4G and WiFi are all in the same boat in that they will kill your battery if your phone has to constantly scan for them. To my knowledge using WiFi is better on power than 3/4G, but that is only if you are connected to a good signal and your phone doesn't have to search.
Also, I have noticed that the WiFi antenna on my charge isn't all that good, so you may want to keep an eye on it during your day. You may find that it is losing WiFi and scanning without you realizing.
The LTE radio in the Charge can be a huge hog. Especially if your in an area that likes to switch between 4G and 3G. Both my work and my home switch between 3G and 4G a lot and its not uncommon to see my phone drain almost 10% in an hour. On a good day it will be 5% an hour with LTE enabled. With mobile data and wifi off it can go down 0-2% per hour.
As far as I know, this is most likely just a sign of the Charge's battery. I'm not sure what Engadget was smoking in their review, but my Charge gets pretty horrendous battery life, especially in areas with dodgy signal (think constant switching between 3G and 4G). This is the first phone I've bought extra cables for charging in the car and office, but honestly, with these things getting as crazy as they are, I think this might be the norm in the future, what with battery technology lagging behind so much.
Some tips I've learned: turn the Wi-Fi radio off when not in use, and if you're in a really low-coverage area, consider even turning data off (you'll still be able to receive calls).
I live in NY, which is absolutely blanketed by 4g. I get better 4g reception than 3g in some places. I am getting horrific battery life. I just wiped, then mounted each partition individually and wiped and then reinstalled gummy 1.8.5 and per imnuts' recommendation, not install the reboot options. I had a custom rom on this phone within an hour of purchasing this phone, so I can't compare stock to a custom rom's battery life. I just know over the few days I've had this phone, my battery has been terrible. I shudder to think what the Thunderbolt must be like.
Your battery may be draining fast the first boot. Just reboot it. If that doesn't work then it didnt flash properly. Just reflash everything and remember to clear data, cache... hope it helps.
You can download an overclocking app and reduce battery use IF you already solved the battery drain problem.

Going nuts!! Battery...

Have to charge almost twice a day... I believe it happened after latest 1.45.531.1 update....
Disabled all animation, got auto adjust for display, disabled all what I could.. Still gives me 12 -16 hours on standby only....NOT even using the phone!!!!
Does anyone have something like that??? Or there is some remedy I skipped?
Sorry if I repeat someone's question.
Running full stock, HTC battery.
Thanks in advance!!
Tester.
PS. Recently exchanged the phone.... First one R.I.P......died completely, didn't even charge.
Is there a chance they swapped a refurbished one on me??? How to find out???
can you provide a screenshot of the battery usage graph? also, have you tried getting an aftermarket, bigger battery such as the anker?
I was the same way as you. I checked my battery graph, and standby was using something like 80% of the battery with almost everything turned off. By the time I got home from work I would need to charge it immediately. I bought one of the Anker batteries on Amazon for $15 bucks or so, and I'm now getting about 2 days for a charge. I don't know what it was with my battery, because it sounds like my experience wasn't typical, but I didn't really feel like going through HTC when I could just pay the $15.
I'm with ya...
This phone was running PERFECT prior to the HTC update. Now I'm having a plethora amount of problems, including the battery. For example, prior to the update I would get 13-16 hours on HEAVY usage... Moderate usage? Try a day or day in a half. Now take today for example, I unplugged my phone a little before 7am and I had 20 something percent 4 hours later.
I'm telling you, that HTC update really messed this phone up IMO.
Thanks, guys!!
Will try to get Anker battery, I believe it's 1900 mAh.
But again something running on the background with that update. We'll see.
I'll try to get the graph, maybe someone'll get some sense of it...
Much appreciated,
Tester.
here are the battery stats...
Display..........74%
Cell standby...13%
Phone idle......11%
Voice calls......2%
THAT'S IT!!! Nothing else is running...... SUX...
Still gives 12 - 16 hours of life on almost idle......
I hate to say it,but if you're battery's dying a lot faster after an update,a bigger battery won't help much.
I'd be getting in touch with HTC and ask them what the heck is going on.
Really annoyed with the battery performance. I checked and only display is using 90% of battery. Tried everything to reduce it but no change.

I've had the same issue since the update. My battery drains at a ridiculous rate. I've become really frustrated with the phone since. I rooted it and flashed a custom ROM in hopes of solving the problem but it's the same deal.
I've confirmed it's not the battery either since I've got another one I've tried and only get the same results. Even with Juice Defender running I get nowhere as great a battery life as I did before the update
I'm doing decent 8hrs 20,mins on batt. With 40% left mostly text and internet browsing

Try clicking the graph at the top of the screen it will give you another screen that shows awake/screen time etc. Is your phone going to sleep when you screen turns off?
I was having the same problem and realized that some app was keeping my phone awake even though the screen was off. I uninstalled 80% of the crap I had installed and now my phone sleeps like it should and battery lasts amazingly long time.

How can you tell if your phone is going to sleep when you lock the screen? What is a good method for this? And if I find it its not sleeping when it should, is there a way to find the culprit easily?

Click on the graph in battery stats, it should show awake time and screen on. If your awake time is constant when the screen on time isn't, then chances are you've got an bad app somewhere preventing the phone from sleeping
my battery life was plain **** on 2.3.3., device was running hot all the time (=waste of energy), charging took ridiculous 4h+! When I took it off at the charger around 23:00 the battery was dead at 14:00 the next day with most time being idle!
Since my update to 2.3.4 things got so much better. charging takes around 2h and battery finally lasted a whole day and had 40% juice left in the evening.
Since I got my 2 Ankers+charger for 20$, battery life is crazy now. Been on one charge for 2d2h and still had 16% left. Pushmail on, wifi on (cellular data only when not at home), brigthness at 100%, taking video, pictues and some navigation, messaging and phonecalls. Oh yeah and a few minutes of flashlight use
I would say between slight and medium use.
If 2.3.4 worsened your batterylife, contact HTC or your vendor.
I now replaced the battery at 16% with the other Anker because I still need to do my 5 charge cycles on that one to calibrate it.
Here's an example of the graph. At the bottom you can see awake and screen on time. I pulled phone of charger last night, did some browsing, then ran for an hour with music playing in the background (you can see the small green bar on awake even when screen is off). After I surfed a little and left it off the charger when I went to bed. The phone is properly sleeping when the screen is off and almost 16 hours and still have 62%.
Before I uninstalled the apps, the awake time was solid green across the screen.
Anker battery worked wonders on my device. Before I would have to throw it on the charger after lunch as I like to go for a beer after work and the stock battery would never make it that far... Now when I get home from the bar I still have ~30% battery. Anker battery FTW!
flash a custom rom and u will go gaga over ur battery life. definitely works for me. on standby overnight drain 0-1%.
I found out that if you don't have strong signal at your location your battery drains pretty fast that's why I always connect my phone to WiFi at my apartment where my phone looses signal sometimes. now I lose just 1-2% of power during a night.
Sorry to hear about your battery troubles. A couple days ago I rooted and switched to "Android Revolution HD 3.0.4" and my battery life seems pretty solid. I wasn't having battery life issues prior to this though.
I'm currently in the process of calibrating the battery:
- drain it mostly
- turn off
- plug it in overnight while still off
- in the morning unplug, wait 15 minutes, replug for a few hours; do this ONLY ONCE or you may damage the battery
- power on, immediately go to recovery, advanced, reset battery stats
- start normally
- drain battery until it shuts down; a continuous stress test or stability test app is probably ideal
- once it shuts off, turn it on again to double-check that it's dead; it should only come on for a second or two
- while off, plug in and allow to fully charge; no fooling around with plugging/unplugging, just normal
- calibration complete!
I think you can follow a similar procedure (minus clearing battery stats) to refresh the battery calibration even without rooting/custom recovery. I've read the effectiveness is similar. The phone just needs to be retaught what "full" and "empty" mean, all in one charge cycle. If you calibrate it wrong you could have issues with it shutting off while still reading ~15% battery life.
Anyway, as I said, I'm in the process of doing this. Currently I'm in the "drain it" phase... with my screen at maximum brightness (remaining on), overclocked to 1.5 ghz, I've been running "StabilityTest" (from market) for one hour and fifteen minutes. It stresses both cores as well as the RAM. At this time, my battery is at around 30-40% or so, and it's getting really hot! The phone's temperature is reading as 54.8 degrees!
Also, yesterday I used the GPS for about 4 hours before it died, this was prior to any calibration attempt. I think this is within typical battery life considering that the screen stays on.
TL;DR: Maybe you just need to try a custom rom or recalibrate your battery. Miscalibrated battery can be caused by flashing/updating a rom, I imagine even when it's an OTA. Sense is crippling your phone anyway, you might as well give it a try IMHO.
get yourself an anker battery..I havent charged my phone since the day before and now i have 20% left! heavy usage

Faulty Hardware Battery drain?

Hey everyone,
I recently upgraded to android ICS 4.0.4 from 4.0.3 with the hope of the battery issue no longer an issue with my nexus s...
Though my battery drains around 1% every 2-4minutes with normal use, as in just scrolling and going through settings (not using apps), very very light use. I have factory wiped it , I have installed new roms and kernels - mixed and matched, uninstalled apps and installed apps one at a time (to see what drains), I even disabled some the high % wasting applications...
My screen dim is on the lowest, wifi is off, data is off, sync is off, gps is off, screen rotation is off, yet still no improvement, I even fully discharged my battery and re-charged it (while phone is off)- no improvement. And i also changed the CPU settings to 800max and still no improvement.
and when i'm playing a game or something it drops around 10% in ten - fifteen minutes, sometimes drops more.
When my screen is sleeping it takes around 1-2% every 1 hour-2hours, which I think is normal.
My screen is usually 45-50% Battery used by the display and backlight
Android system is usually 15%-20%
Android OS is usually 3%-10%
My battery is only about 4-5 months old, and I've always charge it when its 5-10% left, I don't let it die. I'm going to purchase a new battery to see if the problem occurs, if it does, can it be something with the phone hardware?
But any suggestion on what it is?
I've looked around on forums etc and none of the solutions have worked.
The display is going to use the most. There is no way around it. What are your average use times? If you're only losing a few % an hour idling, that's great! The only things I can think that would help is using black backgrounds whenever possible. You also have to keep in mind you're gaming with your phone and that's CPU intensive, which will cause more drain.

Yeah the display will use the most, but I remember it used to be around 30-35%, I've just been seeing how the battery is lately - just going through settings etc and it goes down every 2-3 minutes by 1%, it used to last much longer than that - 1% every ten mins. Sad thing is - I do use a black background lol to save battery and with games I hardly play them but when I do bye bye battery.
try battery callibration apk from market before you recharge your phone and no use 3g just 2g and make conservative 100/1000 the governor.

I'll try the battery calibration and see how that goes, and change the governor as well to see if any improvement.

Android OS is usually 3%-10%
My battery is only about 4-5 months old, and I've always charge it when its 5-10% left, I don't let it die. I'm going to purchase a new battery to see if the problem occurs, if it does, can it be something with the phone hardware?
But any suggestion on what it is?
I've looked around on forums etc and none of the solutions have worked.

Yesterday morning i charged it full 100%. I took it off the charger and left it on the table. It had no wifi or games running at all( at about 8 am) I leave it there all day until about 6 or so. and when i come back its down to 30% WTF IS THAT!. On my dads phone he could have 1% battery and leave it standing by all day and night and he can still turn it on without losing the last percent. Its not an iphone either. Hopefully 4.1 Jelly Bean will have some battery fix for the nexus
BetterBatteryStats. Your best friend when it comes to battery life.
Yeah. Mine isn't bad, but I also just go by my screen usage. If can't get at least 3 hours by the end of the day(which is probably 13 hours), then something is up. Note on calibration, it won't do anything. Those stats are reset once the phone is charged past 90% IIRC. On top of that, our batteries have a different way of reporting the charge. It's not the same as htcs.

I managed to get my screen down to 40ish% and my Android system is under 10% and I've been timing my battery and noticed every 4minutes exactly it still goes down. I tried calibration does nothing as you said. I'm gonna download betterbatterystats and I have cpu spy running atm...

xda will do it!
I have the same issues. 10 hours max not touching the phone at all. Stock, custom, matrix, nothing helps.
Maybe 6 hours if I start using it moderately

Similar issue here. Tried all combinations of ROMs (jb,ics,gb) and kernels (air,marmite,matr1x,lucid) to no avail. Even reverted back to stock GB ROM, radio, and bootloader. Nowhere near 6 hours talk time or 200 hours standby time. I get between 8-10 hours standby time if I'm lucky. I even tried turning the phone off overnight, with a full charge even, and when I went to turn it back on in the morning the battery was dead and I had to plug it in to turn it on.
I picked up a new battery today but the issue seems to persist. I put the new battery in at noon with 98% charge and now 2.5 hours later I'm down to 70%. I am convinced there is a hardware problem that is causing the battery to drain excessively. GSAM Battery Monitor and stock battery stats all look normal with screen using the most battery followed by Android System etc etc. Aside from the battery problem, the phone is awesome and I really don't want to have to buy a GNex when this phone is still salvageable.
So what part of this phone could drain the battery so fast with the screen off? It could be the CPU, GPU, screen digitizer perhaps?
I know you tried with your old battery, but could you try again with the new battery with your phone turned completely off? If there's a drain, then there's definitely a hardware issue.

Phone off for half hour yielded a 9% drop in battery life. I'll keep the responses in this thread only. I just realized every time I respond to a thread it gets bumped to the top of the forum!

Definitely something wrong. I don't lose anything with phone off, so something is messing up hardware wise. Did the phone get water damage?

Battery Life Question.

Hi everyone,
I noticed that my One X has been losing about 12% of battery life while asleep for 8 hours (while I'm sleeping). Is that normal? How much battery life do you lose when you don't use the phone? I leave wi-fi on and that's about it. I checked to make sure that the phone isn't awake during this period.
My battery life has been good on some days (lasts about 20 hours) and bad on some days (lasts about 10 hours) with almost identical usage. Any tips on improving battery life?
I went camping and put my phone on airplane most 80% of the time except when I needed it. It lasted me nearly 3 days! Does LTE consume a lot of battery power? Does wi-fi do also?

Yes to both of your final questions. LTE uses a ton of power. I went to the San Jose area where it's only HSPA and my battery was phenomenal. Wifi may drain significantly if "best wifi performance" is enabled in advanced wifi settings.
Check what uses your battery overnight. What process does it say under power in settings? 12% for 8 hours isn't really that bad..

Wifi consumes the least power of all, but like the post above says, if you have "maximum wifi performance" enabled in your advanced wifi settings then it will prevent your phone from going into deep sleep and drain more battery than it would if that option was not checked. Overnight I usually drain about 1% an hour or less (on both CleanROM DE and AOKP M6.2).
I think it's not LTE drains the battery. It may be because of searching of networks when signal on LTE is bad.

It's sort of both. When you have a good LTE connection while using data then it uses up more battery or if you have a poor connection without using data you will use even more battery or if you have a poor connection while using data that would be the worst for battery. But if you are in a good coverage area and not using data then the battery should be fine.
Drain of 12% over 8 hours (1.5% per hour) of screen off time is pretty damn good. Certainly nothing to complain about. I get somewhere around 2.5% per hour overnight.
Phone battery last forever when in airplane mode. The phone radios are a big consumer of power, often second only to screen-on time. Way back, I had my old HTC Tilt2 in airplane mode in a location with no cell service (basically just using the phone as a watch and camera), and it was on track to last about a week (maybe more) before needing a charge.
12% is what I get overnight. But If I turn off WiFi before sleeping then I get around 5% loss so turn off WiFi if you need more battery.

I feel that most people would get better battery with WiFi turned on. It seems the area you place your phone overnight is not getting a good WiFi signal and/or you might have some of your settings to sync or download while on "WiFi Only".
It varies from person to person and it usually ends up being something in the settings, specific apps, and/or quality of connection (mobile or WiFi).
