[Q] Android System battery drain - Huawei P9 Questions & Answers

Hi everyone!
Last week, I got myself a Huawei P9 since I managed to crack my HTC's screen and my carrier made me a good offer.
I didn't really like the P9 at first because of the EMUI and its "iOS-ish" look, but after installing the Google Now Launcher and a theme with stock Google icons I'm back to the Android experience I know and love and I like the phone as it is now.
There's just one problem that keeps my new phone from being great - its battery life. And that's the reason for my post.
I've used my phone normally today and I've got 60% battery left after 9hrs of usage with roughly 1hr of SOT. Coming from the HTC One M8, this seems like a pretty bad battery life to me.
"Normal usage" means auto-sync enabled, WiFi, BT and everything except 4G disabled, receiving some WhatsApp messages and responding, about 15mins of Facebook, 30mins of listening to music (with the built-in music app) and occasionally checking the clock. My power plan is set to "Smart" and the only apps that are allowed to run in the background are the launcher, WhatsApp and Snapchat so that I get notifications.
What really striked me as strange is the unusually high Android System and Mobile standby drain - These are the highest entries in the list with about 30% each.
Mobile standby says it's been searching for a network for nearly 8 hours when I had a stable connection the whole time - may this be the problem that's causing the battery drain?
Also, I feel like the Android System shouldn't be as high on the list as it is. On my other phones it wasn't even at 1% most of the time. Is this a known problem with the P9 or is there something I can do to prevent the system from draining my battery?
Thanks a lot in advance!

I had the same issue on my p9 plus. Android-system was allways using over 30% battery. After I updated to B161 firmware the usage dropped to15% max. Mobile standby is still quite high in my oppinion.

Same here, I'm on B136, no new updates available for me, Android System is always over 30% of battery usage.

Same for me. Hope the B16x update will come soon my international version
Anyway I go trough my day so that's ok for now.

Yes, android system is always on top, but battery life is still incredibly good. I get 10 hours S.O.T, easy. Also standby is fantastic, it drops 2-3% in 12 hours. This is on Wi-Fi only and no games.

"Incredibly good" is something different for me. It's not bad though. But over night I get a drop of 10% in 8 hours...

So, I get that this really is a Huawei-related problem, then?
Well, that's a real shame. I mean, I can get through the day no problem, that's not the thing that bugs me, but the high drain without really knowing what causes it annoys me.
Here's to hope Huawei releases a fix for this soon.

I also average about 2-3% in around 7 hours.

But this is with mobile connection on or just wifi?

Well, I'm down on 46% now, android system used 30% and I only used my phone activity with screen on for 1h40m. So I hope for an update soon.

Thats about what I get..

Using my phone since 6hrs now, 1hr SOT and 60% battery left with Android System using 35%. I'm really inclined to switch the P9 for a Nexus 6P tbh.

If I turn off data connection and use wifi only I got very good battery life indeed. After 11 hours of usage and 4:30 sot i'm still staying at 50% capacity left.

Yeah, but that isn't a viable everyday solution for most people, I guess.
But may this be a problem with the radio, then? Or maybe with Huaweis own CPU?

I have solved my problem with this guy's solution: http://forums.androidcentral.com/hu...rnight-standby-battery-drain.html#post5226331
Hi, I solved the problem. I did all of the stuff mentioned before (factory reset, wiping cache partition, turning off all google services - locations etc.) and none of them worked. "Android system" still consumed the most of my battery power. The problem in my case were with the SD card. Previously I had an Asus phone, and when I got the new what I'm currently using (Huawei P8 lite) I didn't format the SD card. Android keeps putting its files to the SD card to work properly, and I think the two different versions of Android's SD card files didn't like each other. I formatted the SD card with the phone and since then, no battery draining problems. I hope it works for you guys too.

[Q]Battery Life on LG O2x, how to make it last long?

Hey guys, just got my O2x a week ago and its great. It was flashed with 2.3 and at some point I tested updating using LG Suite and I went to 2.2.2
Anyway, just asking if how long do your batteries (stock) last? Tested mine about 3 days ago and within a day it got drained. Just using browser and played some music and that's it, no Youtube or heavy games or whatsoever. Already rooted my phone and removed everything that LG has there except for the keyboard, Suite, Mobile Support, and Home Launcher. Still, same results. Please help!!
I have been using the free version of juice defender and that has help my battery a little so I now cab get a good couple of days out of it. The free version only really stops data when the phone is locked but it seems to work quite well. I also installed juice plotter to see when my battery gets eaten.
Thanks will do that. So basically battery drains more if mobile data is on? Haven't really experience that on my old phone (which is not Android OS).

I had to charge mine every night and sometimes 2 times a day.
Now, on a GB ROM, and with mobile data OFF, it last for at least a day (24h). This is with WiFi on (when awake of course).
Install a widget to quickly turn on/off mobile data, and only use it when you need. Then your battery will not drain that quickly.
Sorry for my bad english
My battery "record" is over 2 days Well, actually allmost 4 days, but then I didn't have WiFi on neither..
Mobile data is the killer only for badly done apps. Things like fb and twitter that sync every hour etc. Make sure when you install every app you check its sync status. Make them as infrequent as possible
Also try see how low you can get the brightness. Mine stays at 30% until out in the sun (have a widget to up it).
Remember even if not using your phone at home etc to switch tho wifi on as its much better
On good days can get 30/40 hours between charges when low use

Worth to mention is that to get the less battery drain from turning on the wifi you have to turn of the data. Some people forget that and leave both on making it a double drain.
My only tip that I have that I know works is use it as little as possible. Turn off every thing that's not needed in the matter of syncing.
I'm no expert but is that right? All of the data goes through the wifi when on and connected so data connection is irrelevant surely?
Sent from my LG-P990 using XDA App
Thanks for the input and somehow, I can feel the effects now. Also put LBE Security and turned off most mobile data permission on my apps and even if my Wifi is on, not much of a battery drain but at least it has less loss.
i think that 1day is the real time of this battery with 1charge...intense use...

Yes when wifi is on data is automatically off.... You cannot have both on...
Wifi is no very power consuming when it's connected idle to a network, but think to turn it off if no hotspot is there because network scan drains a lot.

LOL.. anyways, i use juice defender. It does help somehow.
I have a same problem. Using my Optimus with MIUI ROM (Gingerbread 2.3.5) i only have 7 hours.
In my opinion,turning off all data connection to improving battery life, it's not a good idea when we choose Android phone.
So?

O_O My phone came with v20c 2.2.2 and had no issues, ran 3days per charge. Wish I had backups of original ril and BB for they were 100% on any I've tried since going through a bunch of custom roms.
I get 10 hours of *idle* time with 3g enabled. With Juicedefender things are okay, I almost always make it through the day and sometimes even 2 days when I'm not doing anything, but the battery just goes nuts if you use it. Sometimes I browse the web for a minute and bam 5% is gone, and I'm thinking to myself "what the hell just happened?".
You have to be very careful with apps that do not close properly. I discovered that Spotify was draining my phone like crazy and causing it to become very hot (draining it even faster, heat = dead battery in no-time) with no way to prevent this other than uninstalling the app. Then I installed a beta version of Spotify from their website and all is well. AccuWeather also goes nuts sometimes but that's resolved by deleting the widget on my home screen.
I run the latest nightly of CM7. Battery life seems to be about the same as the stock ROM for me. What's interesting is that active 3g data use drains the battery more than playing a game. I can play emulated PSX games for about 5 hours straight on a full battery with data controlled by JD.
Everyone should try the latest rom v20e (or the derivated version topogigi's rom). For me, it improves battery a lot! I don't even use Juice defender (and some people said it worsens battery).
v20e
yes Im on V20e and my battery is preety good !
Almost 2 days and I write almost 100 messanger/day and always wifi on checking emails,fb and more !
Hey guys, haven't posted since testing for about week, I guess...
Anyway, battery seems to be ok now. Juice Defender and Plotter works great, plus now on sleep, it just drain 1% per 2-3hrs or sometimes nothing at all, and its not SOD thats for sure.
Also tried Battery Calibration, it worked somehow also so with lots of messaging, wifi, FB, Tap Sonic, plus downloading torrents, lasted 24hrs in full charge with constant use.
2g + Wi-Fi drains the battery much faster than 3G + Wi-Fi for me. Both have a good signal strength.
Anyone know why this is?

Battery Drain?

When I got the phone my battery was pretty phenomenal (comparatively speaking). But it seems since I took the update that Sprint pushed out a few weeks ago, the battery can't make it more than a few hours with light/moderate use. Its really horrid to be honest. Hoping the eventual 4.2.2 OTA will fix this. But in the meantime I wanted to know if anyone else was having this issue and possibly help identify the source of the problem. (By the way I am not rooted)

Have you checked the version of your Google Play Services APK? It can cause a particularly nasty bug on HTC devices.

Play Services is v 3.1.36 but the actual Play Store is v 4.1.10 which is said to "fix battery drain issue." Still seems to be draining pretty rapidly. Any fix you know of?
Can we see your usage stats?

The Play Store update should have also pushed Play Services, so yeah. Could we see your usage and also your app list/sync settings?
I'm in the same boat, even after the Google Play Store fix.
Seriously, we need usage stats.
Sorry, been working in home WiFi.
Hardly been using the phone since I still have my old Evo LTE and the battery is better on that.

Wifi used up 43% of 60% of your battery? That's like a quarter of your battery gone! Am I the only one who thinks that's weird? Can we see the graph and awake time etc? (Sorry for the trouble, but it's the only way we can tell)

Well, in fairness for the last week or so I've been charging the phone and leaving it in my room. The screenshot was after like a day and a half in which a hardly used it and had WiFi on.
By working on home WiFi I meant talking to ISP and bumping up speeds, for the second time in a week.
I'll post the graph when I get home from work or early tomorrow as the phone has been unplugged for about 20 minutes.

It won't hurt if you actually use it. Watching vids/playing games prevents blown up stats like that.
EDIT: Please, also include stats like screen time, awake time, cell reception, Wifi etc.
This was at work. I hardly use my phone at work fyi.

Dropped 25 ish percent in 6 hours? What seems to be the problem?
With your usage, that would give you a day. I'm happy with 11 hours.
But with no internet connection and hardly any use. It concerns me because usually it would drop 5 maybe 10%. It was great on sleep.
Sent from my HTCONE using xda app-developers app
OK, now that I think about it, you're right. I remember getting more than 2 days on standby with absolutely no use (on wifi).
A day with that kind of usage is really not that good. It's weird because your stats don't show anything odd. I'd like to see some moderate to heavy usage stats though. The kind you say gives you 5 hours. That would help more.
Here you go. About 50% gone in about an hour of use (on WiFi) mostly on YouTube/Twitter or music with regular use of ATK.

I'm having a serious battery drain issue with my Sprint One also, though I don't remember exactly when it started - it might very well have been that OTA update.
My battery drains when the phone is asleep. The phone will be dead in just over 24 hours from 100%, with less than one hour of screen usage. The integrated "usage" monitor shows that WiFi consumes this power , whether or not WiFi is in use. I have a paid task manager app that can track stats over time, and according to it, the processor appears to be running at ~15% constantly when the screen is off. I've tried disabling WiFi and having the phone sleep on just the cell network, to no avail. I first thought that perhaps the poor service at my house was causing it. However, I watched the battery drain at exactly the same rate when in an area with perfect coverage.
Here's the weird part - I tried airplane mode'ing my phone. Airplane mode doesn't seem to stop it. In fact, airplane mode seemed to accelerate the drain! I find it simply unacceptable that my phone will die like this with almost no usage.
I feel that the problem is not a rogue third-party app I have installed. I've used the "disable" option on Facebook, Twitter, and I've removed several other suspected apps. It makes no difference. I even suspected my task manager app; I tried removing it and looking at the integrated one, and there was no difference.

Check to make sure never auto turn on Wi-Fi is checked in Wi-Fi advanced settings. I was going to suggest poor reception since that kills my battery, but you mentioned trying airplane mode.
With screen off and nothing running, it's not surprising that Wi-Fi is the main battery drain. But it is too fast in my opinion too.

Horrible Note 4 Battery Life. Android System Draining Way Too Much Battery.

So I have a T-Mobile Samsung Galaxy Note 4, I got it back in October so yes I have "broken in" the battery. I have checked out several other posts and tried pretty much everything. I've turned off bluetooth, NFC, any and pretty much all useless Samsung features (smart stay, turn over to mute, multi-window), I've got a black wallpaper on for both my home and lock screens, I have greenify AND DU Battery Saver, I ONLY ever use data as I have unlimited data and my building has a shared wifi network which I don't trust, I have tweaked Sync in the settings menu to only sync crucial info from all my accounts (google, facebook, email, whatsapp, etc.). So far the BIGGEST battery drainer is Android System. It is always number one. I've had days where I've decided to push the screen-on time to its limits and have used it nonstop. Screen consumption only ever gets close even if I use my phone nonstop Android System is the biggest offender. I've tried keeping power saving mode on 24/7 but that has not seemed to help at all. I've disabled S Health, S Voice, and several other apps I never use like Google Play Newsstand. I am at the end of my rope I despise this phone for its claim to great battery life but its absolute GARBAGE real world performance. I consider myself lucky to get over 3.5 hours SOT. At this rate I might as well have an iPhone 5. I have no idea what to do.
Here's a list summarizing the things I've done to improve battery life:
Bluetooth off
NFC off
Multi-Window off
All email sync set to Manual
Sync for every account adjusted to isync only crucial info
Pitch Black Wallpaper
Power Saving Mode (Not Ultra Power Saving) switched on about 90% of the time
Using Greenify on all Power-Hungry apps
Closing most apps upon finishing using them
Using DU Battery Saver in order to monitor battery activity
Never use Wifi
No Multi-Window
No Touch Sensitivity
No Side Key Panel
Wifi Calling feature disabled (I never use wifi anyway)
No Download Booster
No Smart Stay
Animations switched off via the Developer Options
Tried using another battery (similar if not identical results)
I'm still getting at the very best if I'm somehow on a miraculous streak of good luck that day: 4 hours of Screen-On Time. It is ALWAYS Android System usually followed by Android OS and then an app or two before Screen (because my SOT is so pathetically terrible)
I love this phone, the display is beautiful, the camera is fantastic, it runs seamlessly (on Nova Launcher that is), BUT I despise the battery life. It has made me resent this phone and I'm seriously considering switching to the iPhone 6 Plus as that has comparable battery life and with it running iOS I doubt the OS would destroy my battery the way Android has been lately. What do you guys do to get such good battery life from this phone? I've tried everything I know!! Please can you help guys?
I'm also attaching screenshots from one of the BETTER days.
I would consider rooting and installing a custom rom, poprock I would recommend for keeping touchwiz.
I don't know.. maybe your battery is the problem.. When I was on stock I had the same issue, but i varied in a weird way. With poprock, battery life has been amazing.

A few people have this issue. I really think it has to do with a corrupt file that was flashed. Maybe no fix but a new phone. If part of the pit file got damaged no fix but samsung.

I'd already seen your thread. It wasn't too helpful for me unfortunately because I'm not rooted. Half the terms you guys were using "Odin'd, pit file, etc." I don't understand at all. I'm running Nova Launcher on this phone. Just typing this comment my battery has dipped from 78% to 74% this is ****ing ridiculous I'm sick of this **** phone I might just switch to iPhone. I'm done with battery raping Android.
I'm in the process of fixing this. I think I may have figured something out. I have been slowly working through freezing applications to figure out what is causing the battery drain. I've made some progress. I really think it is an issue with lollipop system apps.
I am now having a slight dragon from cell standby, but the Android System drain is getting capped. Been in this single charge for 17 hrs and Android system is only 7%
Once I get a bit more firm information I will post my findings.

Some suggestions: check out your Google settings first. Disable Google Now and uncheck their location monitoring settings. Also freeze Facebook (use the website instead). Finally ou can disable sync altogether for a while in case other apps are hammering away through it. Test your battery under each of those conditions. Good luck, be patient, take your time. If your battery is good eventually you'll get to the bottom of it. Use Better Battery Stats to monitor. Most people get fantastic battery life. I rarely use 40% in a day. Over night (8 hours) I lose 2% - that's also a really good thing to watch. If you are draining badly at night, you have major wake locks occurring.

Over night (8 hours) I lose 2% - that's also a really good thing to watch. If you are draining badly at night, you have major wake locks occurring.

Thanks I'll try some of that but my problem is that I shouldn't have to do all of this crap! God it seems like we HAVE to revert these superphones back to pre 2000 dumb phones in order to get any kind of a decent battery performance from them. Samsung just haaaaaad to make the screen 2K. If they'd kept 1080p it might've been better! I might as well just switch to the iPhone 6 plus if I want ZERO functionality from my big screen phone. God I hate this Note 4 and I'm so jealous of people who don't do anything like this and still get 5-7 hours of SOT with their Note 4's. I'm beginning to think they're full of it honestly.

A few people have this issue. I really think it has to do with a corrupt file that was flashed. Maybe no fix but a new phone. If part of the pit file got damaged no fix but samsung.

Nope. Either replace the phone or wipe and start over since u not rooted very little help.
If you're not rooted do this:

If you are scared of root just stay stock rooted. Not a slight at Bacardi. He answers the questions better than us.
I am have the same issue with battery drain from Android System. I have see that issues is there when WiFi is enable the battery drains faster. When WiFi is off and using mobile data it drains normal.

I will be watching this carefully. I have the same issue. Always Android system and Android OS in the top 3 battery drainer. Only, issue I have is I have to use WiFi at home. T-mobile service drops to Edge about a half mile before reaching my neighborhood.

It charges very slow.. I used to charge using my laptop USB.. I kept around 2 hours and charge increased only around 20%.. It was fast in Kitkat.
Oh. Im glad im not the only one facing this. Any solution or we may have to wait for a bugfix?

I tried with Both USA and TW Firmware.. Even tried after full reset.. Still same issue.. I think we have to wait for bug fix or any work around solution ..
I am using the US version, not rooted everything stock. When I installed I faced very heavy drain, even with a charger the battery was going down. After a few reboots everything is back to normal. Battery life is nearly identical to kitkat.
Attaching the screenshots, I am getting more than 4 hours SOT easily with wifi on all the time.

Pretty Impressive Battery life on LP
Battery problem on C5502 (stock 5.0.2 Customized TW fw)
Hey guys,
I think I might have a problem here, I did OTA update over 10.5.1.A.0.283, got 10.6.A.0.454. Everything seems to be working fine, the system is quite smooth, yet battery life is worse than it was!
Cell standby and the OS seem to be consuming way to much battery, my reception isn't perfect, yet I checked in Cell standby and signal loss is at 0%.
I do have STAMINA on, yet according to CPU Spy the phone never goes into Deep Sleep. Isn't that suspicious?
You'll find a few screenshots attached to this post to give you an idea what I'm talking about. I'll try to flash the full rom today and see if it helps, while I'm typing this message FlashTool is creating an FTF file so that I can flash it later. I'll keep you posted.
Also, if anybody needs the FTF file, here's the torrent file link:

I have similar problem. For me the biggest consumption comes from google play service and android system. Really annoying...

From my point of view, it totally depends whether you did an OTA update or flash the new ROM. In my case, I have the Deep Sleep state active for a lot of time, and here's the screenshot:
Did you make a factory reset before/after flashing? Most time this helps.
Think the scan location when wifi is off option (in wifi setting) has effect on the google play service.
Also I am testing what exactly that stamina clock option within stamnia setting does. It seems it affects the battery in a not necessarily good way.
This is annoying. Sony includes all these features that are basically rubbish...

Hi,
I installed lollipop onto my ZR via the PC Companion a week ago, and I used a clean install (repair). My battery life is very bad compared to kitkat. I don't use my phone often, mostly it is in standby mode with mobile data enabled and stamina mode enabled (I added a few applications to stamina mode white list: gmail, facebook messanger, etc.). With kit-kat I had to charge my phone every 3 day, but now I have to charge it every day!!! this is 3 times worse than kitkat. If I check under power management - battery usage, I see a few apps have several hours of 'mobile radio active' (mostly gmail, chrome).
I have searched for this on internet, it looks like it is an lollipop related issue and not a sony related issue. Lollipop has this issue since 6 months now , and they didn't do anything to fix this (there are tons of forums posts about this on reddit, and on other places). I have the feeling Android is getting worse in every new version, and Google hire the most ****tiest developers of all time. They don't even answer to the thousands of user complaints of this issue. I will never touch an android phone in the future.

Disable the stamina mode actually yields better battery life.

Just got my zr update to LP 2 day ago. For now seem like the battery life worse. Need to factory reset after this hopefully that help .
Did India LP update OTA two days back and was surprised see kit ain't charging fast and also discharging quickly. And the main battery consumption was by Album photo analyser services. .. have disabled it and seen significant difference. .

WARNING: Latest Update (9/10/2015 G920TUVU2DOH6) Kills battery life!

I downloaded the tmobile update that got pushed out the other day and have noticed a significant drop in battery life.
A few people here have reported seeing an increase in available ram, I have not seen that change on my device.
I was previously on OH8 (Stock and unrooted) and would get 24-27 hours on a full charge, with 3-4 hours screen on time with the following optimizations:
-debloater used to disable as many things as possible without breaking features such as picture gallery, contact logs, etc
-disabled as many services as possible in app manager
-Android assistant used to kill-on-startup all non-essential apps that i use but dont need running all the time
-tasker used to shut wifi off when not at home/work
-tasker to turn synch on 2 minutes an hour to update emails instead of always on
-greenify to hibernate as many things as i can (non root)
-bluetooth always off
-dark/mostly black backgrounds
-automatic screen adjustment
-wifi calling + VoLTE disabled
for the update i re-enabled all items disabled with debloater just to try out all the functions, and re-enabled a few (2-3) things in app manager, today my usage at work was VERY minimal compared to a normal day, i would say I used it maybe a 4th as much as I normally do.
I highly doubt undoing debloater made such a significant change to my battery life, but will re-disable everything tonight and report back with results. for the record as of this writing I'm at 19% and it's just been sitting idle in my pocket since the attatched SS was taken
I believe the issue is detectable with the previously mentioned "check cell standby" method. go to battery > battery usage, click on cell standby, take note of total connection time, go back to battery usage and click refresh in the upper right, then go back into cell standby and see if total connection time has increased.
I have wifi calling and VoLTE disabled since learning of the battery drain issue this phones had and it solved the issue (cell standby time would not steadily increase), but after this update it has started increasing even with both items disabled
Also, this will be a good time to mention something I've stated in another thread:
My friend got a S6 (hes with ATT) and weve compared battery lifes at work, By the end of work I was in the 30's and he was in the 50's, I just browse the web lightly while he listens to youtube via his bluetooth headset almost non stop (screen on + bluetooth + data/wifi streaming), The next day he txts me at 2pm "19% left", i had charged that night and was already down to 75%
long story short: he gets up to 50% longer battery life than me on any given day (as I said, I can get around 24-27 hours w/ 4hrs SOT with all the above battery optimizations, he only has a few items disabled in app manager) so there is a significant battery issue with Tmobile's S6.

cell standby should not steadily increase and should not be that high, no.
follow my instructions in OP, if total connection time is increasing you are effected by the issue these phones have. If youre on OH8 or lower you can shut off wifi calling and VoLTE to resolve the issue, if you are on the latest update that came out yesterday, I have no idea how to fix it yet.
18 hours unplugged with 21% left. So far it seems decent.

Did you download the 9/10 (OH6) update? does cell standby's "total connection time" increase continuously for you with and without wifi calling and VoLTE on?
Check under advanced WiFi settings if the scanning always available option got toggled on after the update.
Mine did and it was causing quite a bit of drain
in my case, latest OTA infact improves the battery life. After OTA, i have rebooted in recovery , and cleared the cache. wifi calling and VoLTE is disabled as before.
update: re-enabling and again disabling wifi calling and VoLTE stopped "cell standby" increasing, the update must just bug it out. However I'm still seeing worse battery life than pre update.
From the battery discussion thread:
aff219 said:
New update: i discovered by enabling and re-disabling wifi calling and VoLTE "cell standby" quit increasing. For some reason the update must have bugged it but that resolved the issue.
I however am still experiencing worse battery life than before the update. 1 hr left at work and ive barely used my phone at all today, 36% left, it's been 8 hours off the charger. Normally id expect to be around 40-65% right now with how little ive used it. (depending on what combination of disabled stuff im trying)
Further more my friend with an att s6 charged his phone saturday n had it off charge since. Didnt use it all weekend until today at work with 20 min charge in car.... Been on bluetooth headset n listening to music/youtube all day. Hes currently at 39%
every day that i compare battery life with him pisses me off more and more. He's probably getting 2x as much battery life as me, without any tweaks or anything. just pure stock.

I had the update since yesterday and so far battery life seems better but gonna test it out for a week and see how it goes. RAM management is about the same however apps don't lag that much anymore. After the update Cell Standby started to affect battery again but enabling and then disabling WIFI calling and VoLTE cleared the problem.

The new update including radios sucks. Much worse battery drain. I also get cell standby bug now showing in stats.

Do what nelson and i said, re enable and disable wifi calling and VoLTE and the cell standby issue should fix, but battery still seems to be worse for me regardless

This is my first time looking at battery since the latest stock update rolled out.
so I havent looked at my battery life since Friday (5 days ago) and this morning I check my phone and the battery is at 94% (charged all day yesterday, was off charger overnight), reported 8.5 hours off charger, that's less than.5% per hour - by far the best battery idle I've seen yet. ( I think prior to this my best has been like 4% an hour)
even more shocking, when going to battery usage it claims that I still have - this blows my mind - 33 hours and some change left before my battery dies!?
Prior to this, my BEST was like 21 hours quoted, with a norm of 13-18.
I have barely used my phone the last 5 days so the usage statistic is scewed a bit, but thats still higher than anything it's ever claimed before.
This friday it will receive ample use, I'll report back with what kind of results I get.
Amen, I'm not the only one who noticed. Also see almost all the old lag is back. I'm so disappointed in Samsung, I've held on to this because I really thought it was the best hardware around...they just needed to fix the software. The update previous to Samsung Pay rollout was 90% there in fixing. Now we're back to where we started from. Full disclaimer, this was the straw that broke the camel's back, I ordered the Nexus 6p
man ever since the update, my battery been not lasting as long as it used to. I used to be able to get thru a 10 hour shift with at least like 30% left. used to love the battery cuz it was considerably much better than my N4. now by the end of the shift, its near dead, if not dead. Another S6 in the family is even worse... its at home all the time on wifi and the battery drains like 10% an hour if not more.
