Hello, when I bought the phone from the seller, the battery was good, about 2 months old. I downloaded another one, I do not remember what the region was before, and what baseband was and build number. So I installed xeu region software. I'm using the firmware for about 2 weeks, everything is fine, but now it's obvious that there is a problem with the battery life. before rebuilding the data, dropped overnight by 1 or 2 percent since I locked it, like 12h lock, after 9h not using one percent or two down but not 10. Wifi is off, the location is on (high-level mode) and increase the accuracy when wifi is off and bluetooth is off, scan automatically, as I turned on this feature in place to increase the accuracy of the location. with battery saving mode i want explain for understand humans turned in location settings wifi scanning while wifi is off and bluetooth scan when bluetooth is off too in location settings. and battery saver turned on in settings backround data and wifi while screen off when battery saver is enable. and from wifi settings while screen off turned off wifi. after these settings battery dropped down 10percent after 3hours. i full charged yesterday i unplug and non used two or 2:30 hours battery dropped from 100 to 99 thats normal. but how gonna did that? 71 ,to 60 per 3 hours???? phone is locked and no background app, location is on but dont remember or i ticket in settings location wifi and bluetooth scanning while off........ before last factory reset without battery saver mode dropped 1 or 3 percent per 8 hours of non-use .. I remembered that I turned on backround data and wifi when turn on battery saver in battery saving settings. all background apps are off. wifi off when the screen is off I changed from always to never which exteneded more battery saver. The battery has dropped down 10% over 3hours. before last factory reset without battery saver the battery dropped overnight by only 1-2 percent. i dont remember when i switch I turn location on or not . and wifi and bluetooth scanned is on when wifi is off.
after last reset from 71 to 60 battery dropped down after three hours with wifi is off when screen is off , location mode is on high level, and i cant remember was on ticket when wifi and bluetooth even is off, i mean never turned bluetooth on when i go to sleep and from battery saver mode ticket backround data and wifi to on when battery mode is on..

1. Bought phone outright and had ke7 firmware but with the tel provider's bloatware as well
- charged for 48 hours
2. Used phone for approx one day before requiring recharge (damn this phone chews thru the battery quick)
- wifi off
- bluetooth off
- gps off
- minimal brightness
- minimal vibration
- power saving feature is on
3. After it's fully charged, flashed it to stock ke7
- lasted 3 days (moderate surfing, calls, sms - couldn't have been happier)
- wifi off
- bluetooth off
- gps off
- minimal brightness
- minimal vibration
- power saving feature is on
4. Yesterday night, charged again when the battery was about 8%. Went to bed soon after it was charged up to 100%
5. Woke up today morning and it's 68% wtf ??
- by mid day it's 37%
I don't get it. When it was first flashed to the stock ke7 it could easily lasted 3 days but after the 1st charge it can barely go pass a day now
My bluetooth, wi-fi, gps is off and my power saving feature is on.
I'm sure i did not change anything after Step 4 (see above)
Help guys? Is the battery trying to learn / calibrate itself ?
Thanks

Have a look at what's been using the battery in Settings > About phone > Batter usage. Also, bear in mind that battery life is also determined by other factors out with your control such as signal strength. 3G signal strength is very weak in my bedroom - I was finding that I was losing around 30% charge overnight because of the increased power cost of maintaining a signal.
Have a look at the multiple battery threads on this forum .

I have Problem With Standby Time .....My Battery After 12 Hours Standby Have 50% Drop.....I install Stock Rom But Itsnt Fix...Please Help Me:crying:
( I do wipe cash and wipe battey and calibrate)
new ugsrii
how long your battery used? if >2-year heavy use, could well be battery degrade. no solution except for buying a new one. (symptom: battery charge sudden drop, like 50% -> 20%).

For me battery drops can sometimes happen when I don't charge battery to 100% - so it's good idea to always charge to full.
First of all you should check if your battery is going into deep sleep mode. You can do that by installing Bettery Battery Stats, and leaving your phone idle with the screen off for some time. You should read the forum post to understand how it works. If after leaving your phone on "stand-by" you realize that it's not going into Deep Sleep mode, then you should find out what is keeping your phone awake.
I used to have the same situation as you, and it turned out that I had set the WiFi Sleep Policy in Viber to override the Roms setting, and consequently leaving my WiFi always on (which prevents your phone from sleeping). After fixing the issue in Viber my phone now turns WiFi off after 15 minutes of leaving my phone idle.
Now unless your battery is actually dying on you, I'm sure you can get a better battery life. I am using Tasker to program my phone to turn WiFi off when I turn off my screen, and then turn it on for 1 minute every 15 minutes during the day, and at nights it does the same thing but with an interval of 1 hour and half. There are apps in the Play Store that do this too, I've tried these both, and they work as they should, and they can even control your Data connection

Deep Sleep Battery Saver
All in all I've been losing an average of 1.7% during the day, and 0.7% and 1.2% per night. My battery currently lasts about 2 days on one charge. This is all assuming it is actually your WiFi that's preventing your phone from sleeping, I just figured I'd share my experience in case it is in fact that; the important thing being that you could probably get the same results as I have (or even better, considering your battery isn't busted) if your phone is actually going into Deep Sleep.
And there's nothing I can do about it. I only have a gear s2 connected at all times and wifi and mobile data off whenever possible. Before I leave to the gym battery is at 44%. After the car ride there it drops one percent. I unlock the phone, connect my powerbeats, and open youtube and there go another 5%. After a YouTube video there is 7% drain. About a 10 minute video too. Leaving the gym and hour later and I see a maybe 20% battery loss. I don't know how people with regular S7s get 4-5 hours SOT because I get only 3.5 maximum. I bought the edge looking for better battery life but it's practically no different than my S5. If anyone knows a magic trick to this, I need to know now because this is extremely annoying.
IF you got the device from an official retailer, just return and get a new replacement. Losing 7% watching a 10' video is not right even with max brightness. You can fix the standby drain by using Forcedoze (which helped reduce my standby drain by 50% to about 1% every 2 hours). 3.5 hours SOT is terrible even with max brightness. Just get a replacement please. It's not worth the time and frustration.
IF you don't have the option of getting a replacement. Forcedoze can help with the standby drain. Factory reset, set up normally (personally, I just turn off bluetooth NFC location and turn them on when needed), and hope that your terrible screen on time is software related.

Do you think it might be my location by any chance? Maybe the service in my area causes this drain. I also have gps on because of my gear s2 but I can turn that off and see what happens. GSAM tells me the in the past 30 minutes the drain rate is 15% per hour. I browsed the Internet a bit and have been using it the whole time. I'll try to also do a full battery drain test on geekbench with full brightness and see what it tells me.

It's a good possibility. I have a fairly weak signal where I am most of the day and only get about 4-5 hours of SOT. I have all radios off except WiFi and data when needed. Still with my usage I only charge every 2 to 3 days. I don't get the drain like you do from watching youtube though.
My battery life also sucks. I barely use my phone during the day and it almost dead when I go to sleep. Most of the day I am connected to wifi between my work or home. My old htc m8 one could last 40 hours. I think part of the problem is because I do not have root on this phone. I kind of regret switching because I cannot get root. I cannot use applications to adjust cpu or control my wifi, data and to turn off apps from starting automatically. I think tonight I am going to try and calibrate my battery.
I had horrible battery life after taking the 2 OTAs. BetterBatteryStats would not report the device going into deep sleep at all and I was losing about 10% per hour on standby. I did a Factory Data Reset and all the problems cleared away. BBS is reporting deep sleep after about 5 minutes of the display going dark. I have Wifi, data, Bluetooth, and high-accuracy Location services turned on at all times. I lose about 2.5% per hour now with AOD turned on on standby.
Guess my advice would be to due a FDR after every OTA....
Guys, I had terrible battery life when I first got the phone. Off the charger at 6am, under 20% by 5pm... Follow my steps below and I bet your battery will do a 180 and be very nice. Mine gets me 35-40+ hours on a charge.
Disable the bloat apps you don't want in app manager.
Turn off Google usage and diagnostics reporting for the Google app, and if you use the Google keyboard, there too. This and the next one were the biggest improvements by far.
Turn off Samsung "Send Security Reports," and in the same place, turn off auto-update Samsung security updates.
Turn off device/Bluetooth/WiFi scanning.
Set keep WiFi on during sleep to while charging.
In permissions, I turned off location for any app I didn't think needed it. I went from 30+ to about 15. If an app requires location to work, you will get a popup warning when disabling location for it.
Lastly, I did a Restrict Background Data on several apps I didn't think needed it.
My phone started dozing and the battery drain dropped way out.
I keep AOD and Bluetooth on at all times and connected to my smartwatch all day, and my car about an hours a day.
Hope this helps! Apparently out of the box the S7/Edge battery life is terrible...

I installed forcedoze and did the adb non-root command and now my phone's battery is holding up better. I think the phone was just sleeping.
It's ridiculous one has to do all this to get closer to acceptable battery life.
Google and SEC should be ashamed of themselves!
It's not just VZW devices either. AT&T are just as bad.
I've given up on trying to get acceptable standby drain and just let the device live on a wireless charger.

You need to turn off all radios when you go to sleep for the device to enter deep sleep. I had the same problem and when I started turning off wifi and mobile data for the night GSAM reported deep sleep and I was only losing 3% per night.

I keep all my radios on (BT, LTE, and WiFi) and BBS and GSAM Pro all report that my phone goes into Deep Sleep.
Was having trouble with both issues, pulled battery with phone on, waited a minute, put battery back in, both problems fixed!
isnt this bad for the phone? Im having horrible battery life so I'll try anything but just wanna make sure

You wouldn't want do it if on a regular basis but you can try turning phone off, pulling battery out, putting it back in after a minute and if that doesn't work, try my method.
I would wait until the battery is super low and then reset network settings under the reset menu. Power down, pull battery and sim wait 30 sec to a minute and replace everything. Then plug in the phone first and then reboot. Let it charge completely and for about 20 minutes more after it reaches 100. If you do a lot of rebooting I have found the phone has issues. I only reboot with the phone plugged in, otherwise it drops 2% every reboot..
Be careful, I did that with a ZTE Zmax 2 once (75% charged battery) and it sent a phone into a bootloop. The only means of fixing it was that I luckily had a 2nd Zmax2 laying around and used its battery on the bootlooped phone which remedied the problem. Both batteries work fine , I just swapped them between the two phones.

I used to worry about this too. This is my first LG product and it MAY be different but at the Sprint store the first thing they would normally do is pull the nattery to look at the ESN. They never bothered to power it doen forst so I asked a couple times and was told it will mot hurt anything. I had Samsung products for uears and have done battery pulls at all levels of charge and for many reasons, but I never had a problem as long as the battery had enough juice left to boot the phone. If not I had to charge it, LoL.
Just thought I would share, I personally wouldn't worry.
I know on my old Nexus 6 pulling the battery with phone on was only an issue with fsync disabled using a custom kernel. I think most phones have built in protection to stop this from damaging the file system.
so a battery pull is your fix? lol some ppl should be hard resetting every so often regardlessi reboot at least once a day
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017

battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.
While I don't get extremely bad battery drain. The few times I've noticed it going down a bit faster than normal have had Android system at the top of the list or at least 2nd in place. A reboot usually fixes it for a while. This has happened in every ROM I've tried. Also I swear that stupid Wi-Fi scanning when WiFi is off option in locations settings turns itself on when it feels like it. I rarely turn my location on and I've checked a few times and that feature is on for whatever reason
Power down.
Pull battery.
Hold power button for one minute to discharge any juice that may be on the motherboard.
Let phone sit for 30 minutes.
Put battery back in.
Power up.
The motherboard and battery should now be re-calibrated. If you still have problems, try a new battery.
Hi everyone.
I bought my V20 in July of this year and in the last week I have started to get big battery drain. Usually it's Android OS and Phone idle up the top of the list.
After unplugging it, the phone will be at 100% battery6 sometimes an hour with light use (eg browsing reddit or general Web search) then its a fast decline in battery life. I can usually tell it's happening because the phone gets hot in my pocket.
It's unrooted btw.
Android OS
I find that if i turn off location services and location scanning for wifi and bluetooth scanning and not use auto brightness and use comfort view i get a full day of battery.
Try Off auto sync, nfc, gps etc
