Lithium ion batteries like to have a charge. All the scientific reports I've seen give no indication to drain to 25%. These aren't your old NiCad batteries.

Do you have a source for this info?

Very basic battery tweaks I've used: http://xdaforums.com/showpost.php?p=60905818&postcount=27
[Verizon Samsung Galaxy S6] HowTheFlip:
Hey guys, I literally created an account because I wanted to post on this thread as well to see why my battery drain is so bad. After reading through, I did a fair amount of what was mentioned in here to try to reduce battery drain.

Basically, I:

Disabled the following apps-

Amazon app suite

Amazon Kindle

Appstore (Amazon)

Amazon Music

Briefing

Google Play (Books, Games, Movies & Tv, Music, and Search)

Google+

Hangouts

IMDB

Message+

Milk Video

NFL Mobile

Slacker Radio

On top of that list, I also have my phone rooted, so I have a ram booster, as well as greenify and cpu tuner on my phone. I set the Wi-fi to only when plugged in to when screen is off, turned off always allow scanning, removed google from smart lock, shut off NFC, shut off Bluetooth, and shut off GPS. After doing all this, I went to bed with the device off at 97% at about 1am where it was not touched at all. When I woke up this morning at 9:30, it was already down to 75%. That's a 22% drain over night with literally the minimum settings running possible.

Sorry if the pictures came out huge, as I mentioned this is my first time. I would have also posted the screen on time but I did not see it under display settings like I see it for everyone else? I'm assuming it couldn't be any more than 20 minute though since I literally went to sleep, then woke up and played around for 20 minutes before jumping on the computer. Also, because my line is a business line, I did not have control over whether VoLTE is turned on or not, so it is default off for me and would have to call concessions to negotiate them turning it on. So overall, that is the only detail I missed on the long list and still have crazy battery drain. I even cleared the cache.

The only thing I didn't do was kill all tasks before going to bed, but between greenify and cpu tuner, that shouldn't be an issue. I'm about to install the cleanROM that has just been created to see if that helps it out.

Literally all that stuff did was change system idle from being at about 50% to now non existent, but still the battery life goes just as fast.
[Verizon Samsung Galaxy S6] Gizmoe:
You should try using odin to flash stock tar. That seems to be the most successful trick. This is my battery(image below). It's a lot better than before I did. Also if you have play services going up to 20% or more uninstall play store updates and play services updates. Then update manually from store.
[Verizon Samsung Galaxy S6] droidiac13:
Google Play Services is sucking the life out of my battery since the update. Has anyone else seen this?
[Verizon Samsung Galaxy S6] Gizmoe:
Uninstall play services updates and play store updates. Then just update play services manually from store. This fixed it for me.
[Verizon Samsung Galaxy S6] brky1996:
Hi. I have a question. I want to buy samsung galaxy s6 edge. But ı have a one problem about this. Battery life. You used Htc one M8 and now you are using s6. Can you compare batery life M8 and S6? When you use M8, how many time did you see sot? And can you compare these at the same condition. And if anyone have information about this question, you can answer me. I wonder this question. Thanks a lot. :o
[Verizon Samsung Galaxy S6] snk012:
Is this normal? I ODIN'd the OE2 update and then rooted with ping pong
[Verizon Samsung Galaxy S6] ikenvape:
I would give it a cycle or two. It will clear up :)
[Verizon Samsung Galaxy S6] snk012:
This was after 2 cycles. I got it figured out though. Downloaded https://play.google.com/store/apps/details?id=com.vitula.batterycalibration and all seems normal now.
[Verizon Samsung Galaxy S6] twiz0r:
Has anyone had the cell standby issue and gotten a replacement and noticed an improvement? I've tried all of the workarounds (while on both versions of clean and OE2) with no luck.
[Verizon Samsung Galaxy S6] hitman4274:
normally those battery configuration tools are useless, but in this instance it did what you needed, those apps clear that list..
[Verizon Samsung Galaxy S6] snk012:
You know I think you're right. Last night I tried to drain the battery as much as I could before charging again. Today it showed me 4 hours left with about 95 percent charge. My battery readings are inaccurate as later on 80% it said 9 hours left.

Any advice on how I can get an accurate reading?
[Verizon Samsung Galaxy S6] snk012:
Just wiped my battery stats and after a full cycle (ran a YouTube playlist until I got the batter low notification). For the most part depending on use I think I'm getting 7-10 hours. I keep everything synced and gps/location is on high accuracy. I don't keep Wifi on since I have UDP. Screen is on auto brightness. What I can't figure out is why battery time is off.. 4 hours with a 97% charge...
[Verizon Samsung Galaxy S6] Gizmoe:
Samsungs stats are very inaccurate until you use it for a while. It needs to re learn your use every time you reset device or wipe battery stats. Give it about a week before you trust anything under battery.
[Verizon Samsung Galaxy S6] hitman4274:
honestly I look at two things, how long the phone lasts with my normal everyday use, Facebook, gaming, forums, instagram... and then I look at the battery life with the phone just sitting idle, like 12-14 hours, a normal work day for me... and in this instance the phone will normally last me 12-14 hours with 3-4.5 hours of screen on time... and if I get that screen off I could probably push it 21-26 hours today was a day off and I only gamed a little, so sat idle most the day the screen isn't even in the list because of Facebook lol

I get AMAZING battery.. before this I got 13 hours at most.
[Verizon Samsung Galaxy S6] OracleBlue:
I have to say I was very disappointed in the battery life when I first got my S6. It would only last about 7-8 hours of moderate usage and have to be recharged during the day. Since the OTA update, the batter is much better and I use it heavily in the evening Today with moderate use, I am at 97% and showing approximately 5 days charge left.

I think part of my earlier battery issue was with Verizon towers not working properly as I was always dropping to 1x coverage rather than the normal 4g.
[Verizon Samsung Galaxy S6] furyau:
You guys just need to tweak the device out and get it to a good spot.

Good LTE reception and turning on Advanced Calling helped me out.

Just aim for really low drain while the S6 is asleep.
[Verizon Samsung Galaxy S6] twiz0r:
Correct. When I said I tried the workarounds that was one of them. I also tried forcing LTE.
[Verizon Samsung Galaxy S6] musicfreak190:

No need. I have done multiple times and had help in the CleanROM forum. I ordered my replacement S6 just a bit ago. It will be here in 2 days. If that one's the same I will post more info here.
[Verizon Samsung Galaxy S6] ergalthema:
I came from an S5 and I'm very disappointed in the battery life of the S6. People keep saying that some update should help the battery life, but I'm losing hope. The S5 was a much better device.
[Verizon Samsung Galaxy S6] DroidOnRoids:
I'm so annoyed with this high cell standby!!! I've tried all the suggestions of clearing cache, enabling VoLTE, and even ODIN'd back to stock. WiFi is still causing the stupid high cell standby. When I'm off WiFi, it calms down. This is a pain and I hope there is a patch for this soon.
[Verizon Samsung Galaxy S6] grifforama:

Have someone willing to trade me their 64gb s6 for my note 4. I'm just worried about battery life. Not sure what to do!
[Verizon Samsung Galaxy S6] twiz0r:
It's not that bad. Even with my standby drain I can get 4 hours sot in 12 hours. Without the bad drain I could probably get another 4-8 hours standby I'm guessing
[Verizon Samsung Galaxy S6] tu3218:
Is that with auto brightness? I wouldn't want to have to turn down the brightness all the way and not take advantage of the gorgeous screen.
[Verizon Samsung Galaxy S6] twiz0r:
Yup
[Verizon Samsung Galaxy S6] tu3218:
So with my note 4 this morning I wanted to see how much battery I wouod lose just browsing Facebook, chrome, and messing with settings on auto brightness. Within a half hour of doing all this on WiFi, I loss 10%. I went from 90% to 80. Is that similar to the s6 do you guys think?
[Verizon Samsung Galaxy S6] mi7chy:
Picked up a Verizon S6 64GB Gold on Sunday and so far it's behaving ok with always-on 5GHz 802.11ac with defaults, auto brightness, etc. Maybe not as good as Note II but idles ok and running gaming benchmarks and emulation it gets about 5 hours SOT (disregard the power saving mode, turned it on overnight but it doesn't really matter when idle). Expecting normal usage SOT to be about 6 to 6.5 hours and will test next. Out of box used Smart Switch to do a full ROM upgrade and disabled apps I don't need otherwise it's stock unrooted.
[Verizon Samsung Galaxy S6] tluley51:
Really hoping someone can help me...

Wifi off, GPS and location services off, disabled and greenified all apps that aren't used, sync turned off for things I don't use. Wipe cache every week. Rooted.

Terrible battery life.

Picture because it wont attach as a picture....
[Verizon Samsung Galaxy S6] twiz0r:
Come on bro. Did you search or look at the last couple of pages (same page if you view 50 like I do) of this thread: http://xdaforums.com/showpost.php?p=61203683&postcount=266

You obviously have play store drain....

And for everyone that has the cell standby drain after doing the workarounds: GET A REPLACEMENT!!!!!!!!!! My replacement does not have the standby drain AFTER I did the workaround. 8 hours 12 mins with 7 hours of those being on my home wifi and I only have 3% standby drain. On my other S6 it would be around 15% at this point. If there is any info that I can get off of the phones to help determine that the issue could be please let me know. I will have to send my original S6 back on Wednesday at the latest.
[Verizon Samsung Galaxy S6] tluley51:
Thanks but no thanks, bro. This has already been done by a number of people and they still see issues, chief. Hoping someone with a little more knowledge can shed some light?
[Verizon Samsung Galaxy S6] twiz0r:
You could have gave some information on what you have tried and I wouldn't have pointed it out. :) Wish I had some more ideas for ya. I haven't ran into this one
[Verizon Samsung Galaxy S6] mi7chy:
Just curious. Is the affected one stock unrooted? If not, have you tried using Smart Switch to do full ROM reflash and wipe user partition to see if it makes a difference?
[Verizon Samsung Galaxy S6] twiz0r:
No the first one was on OC3, OE2, Clean 1.0, Clean 1.5. Nothing I did on any setup made a difference.

Honestly I had problems when I tried to use Smart Switch, and I do not know anything about it (never used it). Does Smart Switch do different things than Odin? Like I said, sorry I know nothing about it lol. But if it's worth looking into I don't mind trying it out again
[Verizon Samsung Galaxy S6] mi7chy:
Smart Switch is like KIES and is the official tool for things like updating full firmware. When having issues or when in doubt it doesn't hurt to reflash firmware, wipe user and cache partitions which the tool does for you. You can download from the links on the right side of page.

Lollipop 5.0.x seems to have most devices under the batter strain. 5.1 ought to clear it up but for now

A couple of things that helped me:

- youtube video on cell standby and wake lock - https://www.youtube.com/watch?v=U_KPUQ2wW24

- OnePlus wakelock fix - http://xdaforums.com/oneplus-one/general/fix-oxygenos-wakelock-t3074311

Setup:

Rooted

Clean Rom 1.5

VOLTE off

GSam Batter monitor - to find those pesky apps

Root App deleter - to uninstall pesky apps and bloat apks

Battery defender - night time use to disable wifi and network when screen off while sleeping

Cell Standby - clear cache trick - large use seems due to LTE to cdma switching while in buildings or in pocket

I'm getting this kind of battery life on cleanrom lite. I used my phone for normal things like Facebook, snapchat, yik yak, texts, browsing, watching videos, playing some mortal kombat, and then I ran 3 antutu benchmarks. (just wanted to compare my rooted s6 to my sister's stock s6 and my mom's iPhone 6) I'm pretty happy with the results! I also just downloaded and applied this black and red theme that you guys see in the screenshot. i'm sure that it will improve my battery life a little bit, but nothing too significant. Anyone know how to improve this?

My battery life has easily lasted beyond 24 hours after applying OE2 and then CleanROM! Typical estimate after full charge is 48 hours but I always put it on the wireless charger while I sleep. My friend with his M9 has completely lost the battery battle.
[Verizon Samsung Galaxy S6] twiz0r:
Stats or meaningless...sot, wifi, etc.

But I'm not disagreeing with you. My battery life on clean lite is great :)
[Verizon Samsung Galaxy S6] snk012:
After 2 more charge cycles from my last post. Standby time seems like it's improved..
[Verizon Samsung Galaxy S6] omgi0wn:
I believe that the remaining time it displays is based on your current charge, and usage. In this case you've only been on your battery for 15 minutes and it looks like you used a bit of your battery at the start after coming off the charger. At that rate your battery probably would only last 6 hours. I could be wrong but that's my understanding of it.

Hey guys, does it matter which CleanROM your on? lite or reg?

[Verizon Samsung Galaxy S6] GoBears:
I've only ran regular CleanROM on my S6 Edge. Since I've had the regular S6 I've only used the lite version. All I can tell you is that my regular S6 on lite no doubt has better battery than my edge did on normal CleanROM. Hope this helps!
[Verizon Samsung Galaxy S6] mhemu:
Here are my stats. Everything stock, just disabled the standard apps that most others have. Wi-Fi, bluetooth, and GPS on. These stats are from sitting at home all day connected to Wi-Fi and I have lte signal that isn't so good. Screen on time was from star wars commander, solitaire, facebook, texting, and browsing the interwebs.
[Verizon Samsung Galaxy S6] tluley51:
Mind blowing, really. I did the same thing yesterday and I got 3 hours screen on time and 8 hours off charger and I had 15 percent battery left. Exact same thing too, Wi-Fi on, bluetooth on and GPS set to GPS only.

According to GSAM, I average 10 hours off charge and 2 and a half hours SoT. Completely pathetic. I have tried every trick in the book too and it gets MARGINALLY better, but not enough to be worth turning certain things off.
[Verizon Samsung Galaxy S6] supersmash19:
Mine used to run awesome but lately I've been getting the same as you. At 25 percent today I only had 3 hours sot and 9 hours off charger. I used to get about 4 hours sot and 15 to 16 hours off the charger around 20 percent. Not sure what happened and it wasn't gradual either. All at once my battery just started sucking. Once I'm back in the states I'm gonna see about getting that one free battery replacement because it's definitely dropped to around 80% of its original capacity. I'm gonna try a couple other things first like flashing lite version of clean rom and if that doesn't work a complete restore to stock since I still have another month and a half overseas. Hopefully that fixes it as I'd rather not use my battery replacement so soon
[Verizon Samsung Galaxy S6] anewday:
I'm getting close to 6 hours sot with clean rom lite and moderate usage, auto brightness, nothing disabled or any compromises. I am happy. :D
[Verizon Samsung Galaxy S6] supersmash19:
I'm having some trouble here and would like some recomendations for what u should do.

I fully charged my battery before going to sleep. I shut off the wifi before going to bed and I get up 10 hours later and my phones on 95%. Not great but not the terrible part either. After I wake up I turn the wifi back on and I use the phone for a bit. It's only passed 40 minutes and my phone dropped a freaking 20% and only 20 of those 40 minutes we're screen on time. I'm now on 75 percent and dropping. Anyone have any ideas? My battery used to be pretty decent but this isn't the first time that this has happened to me so I can't keep ignoring it.
[Verizon Samsung Galaxy S6] supersmash19:
It's only been like 2 hours now since I've been awake with very little use and it's on 40% now... I'm gonna just let it drain to zero and fully recharge to see if that helps at all.
[Verizon Samsung Galaxy S6] krelvinaz:
Why would you not charge your phone when you are sleeping?

I only turn off Wi-Fi when I am away, turn it back on at work and home, full GPS, BT only when in my truck and get very good battery life, 15 hours+ before going to bed where I charge my phone while sleeping.
[Verizon Samsung Galaxy S6] supersmash19:
Why should I charge it when sleeping if it's already on 100 percent? I don't think you understood what I meant. After I woke up it was fine and still on 95 percent but then I turned my wifi on and used it for only like 40 minutes and it dropped 20 percent.
[Verizon Samsung Galaxy S6] Gizmoe:
That is beyond abnormal for any device. Time to rma.
[Verizon Samsung Galaxy S6] supersmash19:
I think I may have found the reason for the issue though so I'm gonna try something first and if it doesn't work in getting my free battery replacement for sure.

I searched online and saw people saying the fault is google photos app. I went on vacation for 2 weeks with no wifi and took a lot of pictures. It's been uploading all those pictures now that I'm back on wifi. It's almost done now as there are only 85 left out of the original 1500+ so once it finishes I'm going to fully charge my battery and see how it does. It's just weird because it only goes down that fast when wifi is on so I think this could be the problem as I only have it backup when on wifi. If that doesn't solve the issue I'm definitely getting a replacement though as I can't live with that. I'm really happy that the first battery replacement is free and with a one day turn around window so if it comes to that I won't be without it for too long. Hopefully it doesn't come to that though as I've only had the phone for 2 and a half months now.
[Verizon Samsung Galaxy S6] Squintz:
So I was seeing awful battery life, even on CleanRom 1.5 for a while. GSAM was showing Android Wear as my #2 or #3 app for battery usage (use a Moto 360 daily), and I couldn't figure out why. Well, after uninstalling Android Wear and not wearing the watch, my battery life has drastically improved. I love my Moto 360, but I was getting a max of 8-9 hrs of full battery life before. Now I'm getting consistently 16-18 hrs.

I can't find anyone with a similar issue using the S6 and an Android Wear device, so it's a bit discouraging.
