Info about my battery life

My battery seems to be REALLY bad. Worse than most peoples from what i gather from reading threads. I get about 8 hours from a full charge with minimal use. It seems that my screen is taking up most of the battery, according to my battery use page.... Any one else having major battery drain like I am??

My display is taking a huge percentage as well. Everything else is low percentages. Don't know why. My screen is always either on auto brightness or completely dim.

Give it a while and a few recharges. It should get better. Same thing happened to me. It's slowly getting better. I have it about a week now.

I was getting 7 to 8 hours at first, had my phone almost 2 weeks now and am now getting just under 20 hours with moderate use.
Give it time. My sensation has far better battery life compared with my DHD.

Peeps, you missed most important thing. Look at the AWAKE line. Either OP is playing a lot with th phone, or something is not letting it sleep.

Yeah, the battery really plummets when you actually use the phone (even on low brightness) but it idles quite efficiently at least...

Did u try juice defender? Just asking ify bout the sensation dnt knw either to get it or wait for sumthing else

Yeah, noticed same thing

I downloaded juice defender beta? whatever the free one was. To me that app does not have a good layout at all, either that or I was missing something. There dont seem to be any personalization settings at all. I dont trust apps to work when they just say "im doing something!!" ya know?
Now that I think about it on that charge I was playing music while I worked on my car for a while, that would explain the awake time. Even without doing that battery life is still really bad and the screen takes up 80%+. I will post another pic after my battery dies today. Dont plan on using it much so hopefully it will last longer.
That is good news about life getting better after a week or two though cause 8 hours with moderate use is unacceptable. My MT4G got a good 24 hours with pretty heavy use, I expect this thing to get at least half that.

i use juice defender and under normal use and a few hours of pandora streaming on wifi im at 35 hours at 40% battery

My phone was also drained like madness, within 6 hours it was empty, even if I didn't do anything with it. At the moment it is better, I did a factory reset through the startup of the phone (turn phone off, remove batt, place batt, hold volume down and push on/off button). There is an option to factory reset.
Strange thing was that when I turned off my phone before the factory reset, it was telling 34% batt. Right after the factory reset is was at 89% ???
I use Battery Status Bar app to display my batt in percentage...
But the good news is, my problem is now solved. Battery lasts for more than a day at normal use and 6-8 hours while very actively handeling it.
Looks like it was a reading wrong information or something...

Got 11 hours out of a battery today. So far its been charging for 4.5 hours and is at 94% charge. Takes about half as long to charge it as it does to kill it!
I will give juice defender a try. Seems like it works for a lot of people.

I had same kind of long charging last night. Battery died at about 7:30pm. I plugged it and did not turn the power on. Went to play some ice hockey and after that I turned the power on again at about 10:10pm and it was still charging. At about 11:20pm(still charging) I unplugged for a couple of seconds to see the specs of the charger and then plugged back, surprisingly percentage jumped to 100. It was still on 100 this morning at about 8:00am.
Now I found out that phones own battery monitor tells me that time on battery is roughly 8 hours But when I check the time from Battery Indicator it tells me that time on battery is roughly 15 hours, which is correct.

Seems that a lot of people are getting false battery readings, me included. I did a factory reset last night and this seemed to fix this, at least until now it seems to report correct (realistic) values. I haven't charged the battery after the reset so we will see if charging messes it up again...
I hope this is a software problem, i really don't want to exchange my phone, i don't have any of the other problems.

what sort of battery times are acceptable for this phone? many are suggesting factory resets and all i wonder if i should do it or not. if i charge the phone overnight it goes to power saver mode usually say 8-9pm and then the power saver mode (basically dim screen and no gps wifi remains on) is managing to hold the power till i go to bed and charge it. is this ok?
juice defender seems to be recommended eh? maybe one should should try that before the factory reset. btw if factory reset done whats the best way to restore your phones contacts to how they are now? i mean it took forever to link all the facebook, phone and microsoft exchange contacts and offcourse gmails. dont want to go through that again.

I tried juice defender last night and it didnt seem to help. I lost 45% overnight without me even using the phone! When I fell asleep the battery meter said 100% still and I woke up to 55%. The phone says there is some awake time, wonder what it could be? As much as I dont want to do it I think a factory restore may be an option since nothing else is really helping. Should I wait until the battery is 100% before I reset it?
Some new pics, keep in mind I was asleep for all of this use except for what the screen awake time says.

I would say you battery life isnt that bad, if it lasts a day then it sounds about right. People are saying the batteries last longer after a couple weeks or so. If you do factory reset try and connect to wifi when google is restoring your contacts and such, it makes things go a lot faster.

I managed just over 9 hours on my first charged but I'm recharging it now and it went straight up to 31% when it booted up again :S

Me and my gf both have a Sensation now(i upgraded from HTC Desire, and she a HTC Legend), we are both pleased with the battery on the phones, she uses stock Sense, and i use LauncherPro, though we did learn something from our older phones, the thing that drains battery extremely much is all the notification emails Facebook automatically send(gmail push), these are almost turned off to 100%, next thing is to turn off all syncronisation in the phone you don't use, ex. i use Launcherpro therefore i don't need the phone to update Sense's own weather, and so on.
We both normally charge the phone every night, but i guess my phone would last almost 2 days on days i don't use it that much.
I must say i am extremely satisfied with my phone, the thing that i dislike the most is the camera, or to say it in a different way, if i didn't know the SG2 had a slightly better camera i may have been more satisfied

You should not have anywhere near 100% awake time unless you're using the phone at all times. You have some app that is not shutting down or auto-updating far too often. That's your culprit - find it and your battery life will improve.

OTA 2.3.4 Upgrade - Battery Issues

So I have had the OTA upgrade on my phone for the past few days and the battery life has gotten unbelievably bad. I'm so confused because it seems to have helped a lot of peoples batteries. I have not changed any habits at all and can barely get through the morning. I'm losing 20% just on the 25 minute train ride to work.
Any ideas?

I'm on the same boat as you I hope we can get a helpful answer.

Still no improvement. There have to be more than just 2 people that have experienced something this drastic. I have made absolutely NO changes other than the update and the battery life is absolutely pathetic --- like 3-4 hours pathetic.
And no I have nothing synching.

I'm no expert, but perhaps it'd be worth installing an app that monitors CPU usage. I remember having such battery problems with the Desire HD and it came down the the CPU constantly running at 100%. Perhaps you have an app that took a dislike to the update?
Just a thought...
Craig.

This is my situation also. Battery is the worse battery of any smartphone I've owned, since the update. No root, nothing. I'm either too lazy or not savvy enough to pinpoint this down, as far as apps, what is syncing, how often, blah blah. All I know is I am using it as little as possible b/c of the battery. I have had it 8 days, and REALLY need to call Cust Serv asap so I can get a replacement and see what happens, but I just don't want to go through the hassle of them trying to troubleshoot the phone. I'm also experiencing the HTC Sense reloading when exiting out of apps, and a few other small bugs/glitches, like web pages jumping/skipping around when I am scrolling through them. Sorry to unload on this thread I know it's about battery...

Same problem, but my battery get way way way too hot. All that energy loss getting hot is killing my battery. It gets up to 50+ degrees C. Way to hot and ever since using these 2.3.4 ROMs.

Try calibrating the battery.

You guys also might have gotten a bad battery. I'm pretty sure if you call HTC they'll send you one free if you tell them the battery overheats.

This would make perfect sense if I didn't have my phone from the initial launch day at Walmart and the battery had been great for me UNTIL the upgrade. It's not the battery's fault.
And yes, I have recalibrated. And no, synching is not the issue since everything is the same from prior to the upgrade.

Actually you do need to recalibrate the battery. I had really bad battery life after the ota upgrade, spare parts app and wiping battery stats and now much better battery life than before ota. I have 64% at the moment, unplugged at 7:30am. I used to get 8 hours to a charge right after ota

Before the Update, my battery life was great, except that occasionally I'd wake my phone up to a Battery meter showing a big grey !, instead of the color-coded indicator. A quick glance online said there was something possibly wrong with the battery, or that it was an unsupported 3rd-party battery
After the update, the battery will suddenly decide its ~70% lower than it was several minutes before, and shut itself down. I had to take the battery out, then put it back in, before the phone would recognize that the battery was actually still mostly charged.
The warning symbol mentioned above was infrequent enough, I could believe it wasn't noticed by everyone having these troubles. I think there's simply something wrong with the batteries, but since the 2.3.4 update, the phone treats the problem differently

How did you use "Spare parts"? I downloaded it and I can't find where to wipe the battery stats. I pick battery history and it tells me I'm using gingerbread ROM which does not contain battery stats reporting activity.

An app could be playing up. I know it's annoying but you could try a factory reset and reinstall everything from scratch. I find this helps tame apps that misbehave.
If your phone was fine prior to the update it's unlikely its a battery/hardware issue.

+1, your battery stats got wiped from the update, so you need to do a few complete charge to 0%'s.

Add me to the list of people whose battery life died after the upgrade. I even tired a factory reset over the weekend to no avail. I also tried switching batteries from another Sensation that I have which wasn't being used but no luck there either. In my mind it definitely is a software issue. And to think I used to brag about this phone's battery life!
I just need to root this thing and move on. Was hoping the HTC root process would come out soon. The instructions make rooting HTC's seem more complicated than my Samsung Vibrant which was pretty simple.

How do you calibrate the battery? lawl

If you're rooted, you can download an app called Battery Calibration that will help with calibrating the battery.
Otherwise, basically run your phone up to 100%, then drain it down to 0 until it shuts off, then recharge it back to 100%. Do this several times over the course of a few days and it should be calibrated.

Been experiencing the same thing. Finally got around to checking wakelock, and found that HTC sense had wakelocked the phone for 9 hours (the awake bar in system settings was solid). Some quick googling suggests that in certain cases, the HTC Sense sync can do this, so our common denominator may be that we all have a sense account set up.
I've disabled sense in my accounts, and killed the sense service. We'll see if that "fixes" it.

Weird battery issue

For the past little while my battery has been draining very quickly. It turns out that my power button wasn't grounded and stopped working soon after the battery issues started. I got the power button replaced and ordered a new battery, but now the battery is acting even weirder and I'm not sure if it's a issue with the new battery or with my phone.
The battery will drain fairly slowly (six hours to go from 90% to 50%), but will then drop from 50% to 30% in a matter of minutes and then to 13% even quicker before the phone will shut down completely. I've tried wrong the battery stats but it doesn't seem to have helped.
I'm guessing that it's a problem with the new battery, but I was wondering if anyone had experienced any similar issues? I'm going to switch back to the old battery and see how long it lets as a test but I would like to figure this out soon. Thanks

Hi,
Maybe u can post ur battery stats to help us understand what ur using during the battery drain.
What ROM/kernel are u using?
Is the drainage during WiFi or data usage. If its data, how strong is ur signal?
There is so much that can be causing this so the more info, the better.
Oh, and is the new battery a knock-off? If so that can also be an issue.
Where did u buy it?
Thx

My battery stats from last night were mainly screen and maps. I turned off automatic updating in maps though. I can edit this post after I use my phone a bit.
I'm on stock everything but rooted.
I always leave WiFi on, but the battery has gone from 50 to 30 to dead when I wasn't connected to a network. My signal without WiFi is normally three to four bars, and WiFi is about the same.
The new battery is more than likely a knockoff. I ordered a $10 battery from eBay (my bad).
Sorry about not paying more info. I wasn't sure what else to post. Please let me know if there's anything else you need to know. Thanks

Well if you're stock(I assume you rooted but kept the same ROM) then maybe you can change kernels
or
Look for a ROM that has the stock feel but has tweaks that can save your battery life. There are a few out there.
But you'll get arguments that stock is not always the best ROM for great battery life.
Its a personal choice so look at the ROMs and pick one after you've read the thread to see similar issues/wants from it.
Good luck

If you are on Jellybean Stock then you should seriously consider using a custom ROM because Google hasn't yet released the perfect Jellybean like they released the perfect ICS in 4.0.4 update..
Secondly, you should try cyanogenmod based ROMs whichever have been great when talking about battery life (There are really awesome ROMs out there).
And follow the below mentioned steps and observe for a full 100-0% cycle drain times and get screenshots of battery stats with screentime and post here..
1. Turn the Screen Brightness to minimum; the tolerable value for you.
2. Remove any unwanted apps.
3. Keep WiFi switched off when not in use.
4. Set the multitask value by Going to Settings -> Developer options -> Background process limit -> At most 4 processes
5. Use minimum widgets and minimum home screens if possible
6. Uncheck the location services in settings. You can switch them ON when required very easily.
7. Clear Running Apps from Settings -> Apps -> RUNNING & also by long pressing Home button.
8. Clear cache at regular intervals and always use back button rather than using Home button
If above steps make a difference then it will become your style or else change the battery and get something like from OEM.

I took some of dark's advice, although I had already been doing a lot of that stuff. I'm not complaining about the battery life on the stock rom (I have already accepted that it's not the best), but rather the issue of having my battery drop from 50% to dead within 20 minutes, even without use (not at all normal for me). Does anyone know what could be causing that issue?

My battery seems to be holding strong. I'm worried about what will happen when it hits 50% though.

edit: i'm sort of wondering if my phone is reading the battery correctly. it kind of seems like six hours is a lot of uptime just to get to 50%, so the rapid drop to zero might just be because the phone isn't correctly reporting the battery's charge.
edit #2: my phone got down to ~30% battery no problem before it shut off completely. upon plugging it in to get the phone turned on, the battery had dropped to 20% and then dropped to 17% with the screen off and the phone plugged in

Your battery seems to be good enough to withstand the usage. There is one thing you can still try;
Let the battery drain completely and let the phone get switched off.
1. Now plug in the charger and on the phone go to your recovery. Here I suppose you have the latest CWM recovery.
2. Go to Advanced -> Clear Battery Stats -> Confirm by scrolling. Then reboot the phone and avoid using it before it's charged completely.
3. Now let the battery charge 100% and only after that you unplug it and don't interrupt the charge cycle.
4. Observe the changes in discharge timings. And also paste a screenshot of Screen Usage time by tapping on Settings -> Battery -> Screen (The Time on details...)

I'll try that later. I thought you were supposed to reset battery stats when your battery was completely charged so that's how I did it the first time thanks
edit: i'm just about to reset the battery stats again. my phone decided to show 40% battery as I was walking home, but then shut off and shows 0% battery now that i'm home and have access to a charger. i'll let you know what happens once the phone is fully charged. additionally, my phone will say charged while plugged in when my battery monitor thing says that it's only at ~89%, so I don't know if that has anything to do with it. thanks again

Everything seems to be going well today. I'm about 8.5 hours on battery now so I figure I'll let my phone charge a bit. Thanks again, dark. Hopefully this time it'll stick.

Every battery exhibits different discharge curves vs voltage. The os estimates battery level based on voltage. It is possible that the batteries discharge curve is just very flat throughout with a steep drop in voltage near the end which would produce the results you are experiencing. Wiping battery stats has no bearing on this issue, google cleared up what battery stats really does over a year ago. Best suggestion is to drain the battery fully, charge to 100% and repeat the process several times. This will help both the batteries discharge curve and the os's estimation based on voltage. If the problem persists, buy another battery (preferably not a knockoff) and test again. If you are still having problems after that, you may have a hardware issue with the phone. Does not seem to be a Rom issue, otherwise the drain would be happening constantly, not just after 50%.

New battery, 4V reading after 33 minutes of display... WTF

Hello!
As you may guess from the title, I just changed my battery and after having it charged fully I noticed the the voltage reading on CPUZ was 4300+V after many minutes browsing the net over LTE. Although I'm no genius in voltage and stuff, it seemed to me a little strange and I kept tracking the reading. Right now is about 40 minutes that the display is always on and the OS says 100% (I bet it ain't right :good.
Now, may I have broken the SoC while changing the battery so that the reading could be altered? May this new battery have come from the future where it can store enormous amount of charge thanks to alien technology?
HALP I don't want my phone to explode like a Note 7 :crying:
EDIT: the voltage now seems to have increased even though I did not connect it to the AC. Now I am going to sleep, hoping that I do not blow up. Wish me luck.
EDIT 2: Before going to bed I rebooted the phone. After the reboot and around an hour of screen time it has consumed about 33% of the battery (I had those low consumptions only with CyanogenOS 12 LOL). The SO now seems to be reading the battery correctly. What could it be? Still hoping not to burn down during the night... Good night!
EDIT 3: https://goo.gl/wKB4Bs

This graph shows percentage and voltage of the battery over almost 24h. At first i'm charging, then i use it normally. After many attemps like this one i noticed that the battery life is now normal, but the percentage is still f up. Maxium voltage was around 4.3V, which is fine i guess

Well readings are looks like normal but this is anormal of course. Maybe it is a new battery so it's opening state maybe you need couple cycles to make it adjusted. Is the battery original? And you done all correctly? Maybe clean flash fix it or use it until its dead and recharge while phone off to %100. Keep me updated.

Just do a full discharge-charge cycle and keep it plugged in overnight with a powerful 2A charger. Sounds like your battery needs to recalibrate and that's what this does.

I think it's common bro. No need to worry
I always have that kind of discharge voltage

Thank you all for answering Now let's have an update:

Just do a full discharge-charge cycle and keep it plugged in overnight with a powerful 2A charger. Sounds like your battery needs to recalibrate and that's what this does.

I did it 2 times now, still giving me abnormal readings.

Maybe the voltages are but the percentage is crazy tho!
Now i have few updates:
- if i fully charge the phone, it will keep the reading at 100% until i reboot the phone
- the OS is able to keep track of the consumption until the battery percentage goes below 100%
- rebooting the phone changes the percentage reading always (LOL)
- i did not notice any real increase of the battery life compared to the previous stock battery
Here 3 screens i've done, the first two are from yesterday after the first full charge, the last one has been shot right now. and the phone got detached from charging around 11:00.
The mystery deepens....
EDIT: Just rebooted, 70% battery displayed from 100% rapidly decreasing

Still sounds very strange. I suggest you to go FULLY stock(like out of the box stock) and then use it with stock firmware for a time. Maybe it helps..

I hate stock ROM, i'd rather replace back the stock battery instead. Putting aside personal preferences on ROMs, how can changing ROM alter the reading of the battery? I mean, it does depend only on the voltmeter reading, and that's HW. Are there different ways to interpret the voltage reading? If so, i'd like to see some examples. Just curiosity

yes it is up to voltmeter but voltremeter sends its readings TO the software and i think there is a somekind of cache. And when you unplugged the old battery and replace the new one it might corrupted the reading. But on the other hand replaceable battery phones can do this switch w/o problem. Maybe there is something special or additional thing going on there. And not flashing any other rom but going back fully stock might be the right solution for you because it flashes and deletes everything. Resets everything. After that reset you might as well flash twrp again and flash custom rom again. But maybe theese all just an theory and going back to stock will not help. Maybe only faulty thing is battery but you wont lose anything with trying. As long as you backup your data

I went back to stock (still unlocked bootloader tho) and fully discharged the device then fully charged. Now, at 100% reading i unplugged the phone and started an AnTuTu benchmark to see what happens. Again it was still showing 100% after 2 full tests (the device was crazy hot on the camera, i know it's normal) so i rebooted. After the first reboot was still 100%, after a second reboot it showed 89%. Let's keep testing... Any idea? @zaoms

Hmmm, if you even went back to stock and that not helped i am really thinking your battery is faulty. Have you ever watched oneplus one battery replacement videos on youtube to see if you really done it properly?

Actually now, around 50%, it started behaving normally I think that the stock "needed time" to recalibrate. Rebooting now seems to not giving any problem and the discharge time seems to be reasonable. Now i am flashing back Sultan, let's hope!
By the way i followed the ifixt guide here

well great then! i assume something has been ressetted when you went back to stock and now it collecting data from your battery or something. And put this things together it starts to behaving normally. I hope it continues like that:good:

Ugh! I went back to Sultan and the battery started to ****up again! Now i'm going back to stock hoping that it needs more time to "save" the calibration

It's because of sultan's battery driver. He has changed some voltage thingy (AICL, remember @zaoms). But I'd suggest you to flash another ROM like LineageOS to check if it's the same as stock COS in terms of battery "calibration". Let me know what happens.

The mistery deepens even moar... I'll try as soon as i can but i need a stable ROM right now because i have an exam tomorrow and i need to prepare my cheating table for phone and weareable xD
I'll try tomorrow tho, thank you guys ^^

After few days of testing I'm back!
I'm using the stock rom for a while now and unfortunately the battery has not "calibrated" or whatsoever. Nevertheless i've found a pattern in the battery readings fluctuations. Here's the roll:
1) battery completely discharged
2) charge while turned off until it says 100%
3) turn on the phone, it will now say 88-92%, let it charge until 100%
4) reboot and hope it still says 100%, otherwise go back to point 3
5) use the phone until it powers off by itself
6) turn it back on and it will say something like 60-70% remained battery
7) use the phone until it powers off by it self
8) turn it back on and it will say something like 10-70% remained battery or be really discharged
- if still charged use it until it's really discharged
That's how a battery cycle goes right now with stock OS and unlocked bootloader (just fyi). Any idea of the reason behind this abnormal behavior?
Curiously, when try to turn on the phone in the end it vibrates, does not turn on and does not shows the low battery warning, why?
I'd like to point out that sometimes the reading of the voltage of the battery increases for a moment then goes back to normality while discharging (is this magic?).

Update: i was charging the phone while turned off from 0% and it showed to me the low battery sign., after a while it started charging apparently correctly.
Now after 1h the phone was showing 100%, i detached from the AC then connected again and it showed 100% but started to decrease the charge until 68% then again started charging. LOL

Update: seems like i've get what's not working!
What is broken right now is the charging: the phone is not able to understand how to charge the battery fully. Right now i've found a workround:
- turn off the phone and connect to charge
- wait until you see 100%
- unplug, wait few seconds to let it turn off
- plug again and watch it going backward from 100% to the real percentage
- repeat until it will not fall back
Now it gets really charged up to 100%. How can i automate this?

I saw your link on the ebay feedback profile of the seller. I have the exact same problem and am pretty sure the batteries are just low quality and faulty. Its the second battery this happens. Exactly the same thing. The first time I got such a battery I fully discharged the phone up to a point it wouldn't even get to the boot logo, and the battery died. It wouldn't charge at all and that was the end of it. I don't believe there is any way to fix this but to buy another battery and pray.

Severe Battery Issues... anyone else having this? (results inside)

So one night I left my phone off the charger at 40%... it was about 2am. I woke up at about 6am and the phone was completely dead. 4 hours of STANDBY drained 40%. So I thought I was just imagining things and compared my phone usage stats to my buddies who got the same phone at the same time. Here's a quick comparison... and mind you.. my numbers are after a FRESH factory reset with only stock app updates installed and maybe 2 or 3 of MY apps that I needed. I can't speak to what he's installed, but with these contrasts... I don't think it matters much.
Does anyone have some insight to this, similar experiences? I'm really thinking that I have a bad battery perhaps? I get usage varies by user but I really don't think this much especially considering that I intentionally let my phone just sit uncharged and unused for a good chunk of the day after it hit 100 and I pulled it from the charger.

That's what I thought.... but not after a factory reset?
Here's the Usage Stats from a *#*#4636#*#*.... nothing out of the ordinary

same carrier? Your signal may be horrid in comparison to his.
Could be location, could be carrier. Make sure to take a look. If your phone is struggling to keep a data connection you'll kill your battery easy.

Same carrier, we live down the street from each other. Signal strength according to the *#*#4636#*#* is -92dBm 48asu (whatever the asu part means)

Sorry I don't have anything to add but I had this plague in S7. My battery died very fast.
The S8 has been opposite for me. I was able to get 15 hours out of the battery using it all day (where 8 of it was in a really bad reception area).
I hope you get it sorted out. I could never figure it out with my S7. I did alot of research (all here)

I am planning on bringing it to the AT&T store and presenting my findings to them and demand a replacement. I know that I had no issue chatting AT&T support and getting a replacement but they say that since it's brand new, I need to get support from the AT&T store.

I don't know the battery life on mine is amazing 100% after 8hrs standby. and I was on my phone yesterday for 14hrs doing stuff and that brought me down to 5% from 100. I have most of the gestures and crap that drains the battery off though.
My point is if your not happy with your battery life there maybe something physically wrong with the battery or phone.
It's bound to happen a lot of people are buying these so not every phone is going to work as it should.

I agree completely that there is a battery issue. I've had a LOT of exposure to testing battery life, troubleshooting what impacts battery, etc... and I'm fairly confident there is some sort of battery issue. There are FAR too many people reporting stellar results for me not to as well. Even with how much I use use it, there was someone getting 40+ hours on battery... so I should be able to get 12 right after a factory reset... you'd think

Would love to know what his is. -92 isn't terrible but it's not great. You'd be amazed based on tower placement what even 50 feet can do, much less building materials, etc.
not saying this is for sure it, but i've been in this same situation with another carrier, was dead set it was the phone/battery and so were they, we tried 3 replacements before I gave up and determined it had to be a signal problem. Switched carriers and got the same exact phone, issue was gone.

Mine is exceptionally good. I get 0 to 1% drain overnight. My battery seems to last forever in the day. I don't think it's your signal. I have been in bad signal areas for long periods of time with this phone and no significant drain. I would definitely get a replacement and go from there. Good luck

Absolutely. I have most crapware disabled and all apps hibernated on screen off but this is without a doubt the best battery stats I have ever had on a stock phone.

I had battery drain on my S7 Edge
cos i had Sync from old S6 Edge all the apps
I fresh install each App & that did help
No Issue on my S8+ till now :fingers-crossed:
Chk my Video in Signature

I had this problem, turned off location and always on display before heading to sleep, battery was at 96%. 9 hours later when I woke up, 93%. Before when I had both settings on, my phone dropped by 14 percent overnight. SOT is amazing so far, 2h 40 min at 74%. Will post pics when battery is almost dead.
P.S. - Compared to my Nexus 6 battery, I used to get 3 hours SOT before dying, looking good so far.

I went to the AT&T store and they hooked my phone up to a diagnostic machine and it said the charging system was defective. So new phone and fingers crossed.

That sounds to me like a bad battery. I get about 2.5 days now which is unheard of on my V20.

Wasn't a rogue app, not after a factory reset. However the AT&T store validated there was a battery issue based on whatever test they used. Would like to get my hands on that testing app.....
