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

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.
Hi, I don't know what to do, I'm running 4.2.1 stock on my 32 3G N7. The tablet cannot go in deep sleep because of constant baseband_xmm_power kernel wakelocks. I tried factory reset, but the problem persists. For example with 5h the screen off, there are >4 hours partial kernel wakelocks.
Same here and I'm sick of it. Sometimes my Nexus manages to enter deep sleep but I still see a significant percentage of that kernel wakelock. It also happens that wifi won't shut off on sleep, and I'm talking about when it truly enters deep sleep, and it's correctly configured.
I have the same problem. Battery life is really poor due to this. My LP core is running at full tilt for at least half the time the screen is off, preventing deep sleep.
I found a suggestion that turning on flight mode and then rebooting might help, but I think the problem recurs pretty quickly if not immediately.
Saw a post that said it's due to the modem switching power levels when radio reception is poor. That would definitely make sense in my case — 3G reception fluctuates a lot at home and I am constantly losing connection. I have removed the SIM and will check it in the morning to see if there's any improvement. (Using BetterBatteryStats).
Hope this bug gets fixed in the next update. Almost thinking I should have got the vanilla wifi model
________________
EDIT: Removing SIM overnight doesn't help. Over the course of 8h screen off, baseband_xmm_power was active for 7h 46m!
I'm having the same problem, only when mobile reception is poor. Unfortunately, my mobile coverage at home is currently near-zero, which makes using my tablet as an alarm clock a dicey proposition unless I plug it in overnight.
I've got a problem with WiFi consuming too much battery. I fully charged my phone and did not touch it while it was connected to WiFi. After 2.5 hours, it was at 88% saying most of it was consumed by WIFi and standby mode.
I have "WLAN optimization" turned on. I never had this kind of problem before with other phones - does anybody have an idea what I could do to reduce the battery usage?

maybe you have apps synchronizing and draining the battery, try greenify app to hibernate what you dont need when phone is on standby mode.
All of a sudden, my S5 has started experiencing quick battery drain when wifi is turned on. If I turn wifi off, I get very good battery life.
Any advice?
Same here. Suddenly started on android 5 with custom rom.
Till now I have reset/factory reset, try another rom, try back to stock but still not working.
When I turn wifi on an there is a huge drain. I'm talking about 100-0 in just 13h without usage.
If just mobile network is turned on everything is allright and there are three days battery life.
I have watched with battery doctor etc for some reasen but there is no awake or something.
In battery usage there are missing 80% of used battery just don't listed.
Sounds for me like it's an hardware issue?
Thanks for any help
Sorry for bad english
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.
