Does Cell Standby still drain the battery after updates? (Just bought S6)

Just bought an S6 and noticed Cell Standby was draining power. Searched online and there were a LOT of threads with users complaining about the issue.
Didn't see anything more recent so I'd like to know before updating. I have 2 other S6' also and same issue.

After all the updates and time the S6 has been out, Stock still does have the Cell Standby drain on 5.1.1.

It was on/off for me. Somedays it would be amazing, while others the drain was extremely high. Ended up installing greenify, and made sure the standby drain didn't happen. It's been amazing. I charge it once every two days with regular work day usage (2 email accounts with push, youtube videos, web browsing, navigation, music, and messengers).

Great battery life with MM update

Hello ..
I am getting amazing battery life since I got 6.0 .. Before with lollipop I used to get around 5 hours on screen time. Amazingly though I hit 6.30 hours on the first day after update, and this with wireless, mobile data and Bluetooth on. And no data saving and screen on 70% which is amazing.
Good job Motorola

Excellent I would say
Excellent batt life with this new update very impressive how a software help the hardware to accomplish that task.

I replaced my STYLE and got a new one two days back. The old one would be dead even though it has 80%+ battery.
The current one is pretty good compared with the old unit. I got 4+ hours of SOT and I was on 4G and WiFi all the time. Was using it heavily for browsing and chat.

This is not bad at all. What I am saying is after MM update battery life increased about 1.5 hours extra SOT

Perhaps the update fixed something else? Looking at the MM update from L, there appears to be nothing besides Doze, which only works when the device is still and not used. I notice perhaps 15% better battery life if using the device sporadically during the day (medium use for me). With heavier use, I notice zero difference so far.
I was hoping some kernel adjustments were made, but the device spikes with heat about the same. I first thought it was less, but notice the same apps get the device very warm to hot (the GPU is over it's head with 1440p). Standby time is a lot better though, but only a significant improvement if lighter use though the day (so Doze can be a factor).
Usage is relative only to the user though

How do you get such great battery performance? I barely manage to get 3 hours SOT.
When the device is idle there's no drain, i only lose 2-3% overnight. But when the device is active the battery drains very quickly.
Tried a lot of battery saving stuff, greenify, powernap, and so on, but no luck.
I'm on MM stock rooted. Having a lot of apps installed. May this be the culprit?

If 20% brightness or less, all you do is web surf and a little Youtube, with good LTE signal or wifi and VERY little use of apps that force the GPU to push 1440p, you can get five hours. Everything is relative to the user. That's it.
Counting stock apps, I have 395 apps and 5GB free (64GB model). based on MM battery report, I have no apps that are background battery demons.

Are you talking just 1440p video in general or are you talking 1440p games?

I'm lucky if I get 2 hours of SoT. I can't tell if Android Wear is eating my battery or if it's Sprint, despite having a decent signal. Bluetooth and Cell Standby are chewing up the majority of my battery power. I think the network management is trying to shuffle my phone between their three frequencies and while at work, I can only get on the 1900MHz PCS band due to having to use a repeater.

Some games and apps run at 1440p and choke the GPU. They stand out by running very warm to hot and drain the battery more quickly.

Yes the apps do drain battery.
I uninstalled one particular email app that alone would drain 6% daily!
Anyway this time I got is without gaming. Mostly chatting and browsing and a lot of movies (vlc). I think that day I watched not less than 3-4 hours of continuous movies on the phone.
The only thing I did differently than before is removing unnecessary app permissions and notifications. Other than that I have done nothing. Like I said I do not try to save battery because I always have power source near by, but this 6.30 hours SOT i s awesome I tell you.
Based on my little experience with Android some apps will screw up the phone for no reason. First time I got the phone I got around 3 hours SOT with so many unneeded apps, and I did not know which app is draining my battery so I formatted the phone, and started installing apps one by one and watching the battery. And I managed to hit 4-5 hours with lollipop. Now with the update I got this and I was shocked.

Fully back to stock, unrooted, bootlocker relocked.
Upgraded to MM via OTA.
Installed all my apps via Play Store. Until now, i always restored my apps via TiBu, including data/settings.
I'm curious if my battery life will improve.
Will post the outcome, if any
Cheers!

A lot of the time my phone is just sitting on my desk. It used to say I would get around 1-2 days battery life from it sitting there doing nothing. After MM it says there is 8 days left. I have had it unplugged all day and even with some moderate use I am only at 95%. The doze mode really makes a big impact in stand by times!

I think it did do something to the apps. The way you can block apps from getting access to location or other services is pretty impressive. I love that as I hated that apps would have access to everything on my phone and I cannot do anything about it. Now I can and this particular feature made me love Android even more after I switched two months back.

Is there something wrong with me. I only get 2 to 2 1/2 hours battery tops and actually I've tried amplify (paid version), and power nap and they don't seem to help much. I have only got 3 hours once since I got this phone. Is it just AT&T maybe?

I'd like to mention something else. Probably not related at all, but ..
My old MXS was a faulty unit (as I mentioned in my previous post). Once I got a new replacement, I have not yet charged the phone using Turbo Charger. I am charging it with Mi Pad charger (non-turbo). Yes, it took about 2+ hours to go from 30 to 100%.
Old MXS was always charged with turbo charger and I was getting pretty bad SOT and the baterry would drain as fast as it would charge. Does it have to do something with using a normal vs turbo charger?
I stop pretty much all background services and apps not in use. The only active applications are firefox, whatsapp and VLC.
My screen is set to 50% brightness with adaptive brightness ON. Moto X display and attentive display is ON.
Non-root (planning to root soon) and Moto ROM.

Probably yes. But i would charge on non turbo for two weeks so that I get definite data for comparison.

Less than 3 hours is not good bro, really anything below 4 hours is just bad. You better figure out what is draining your battery, or maybe it Is a bad unit?

what difference does it make if it is charged slowly or not??
It should not matter, if the battery is not keeping the power that means it is defective, nothing to do with slow or fast charging.

Not impressed by battery timings

I'm the guy who gets every flagship as soon as they hit the market. I've been using Huawei mate 9 before and it had very impressive battery timings but it's been like 4 days since I got my s8 plus and not impressed by battery at all, it's hardly giving my 4 hours sot. I've read different threads people claiming to get 6 hours easily. I'm using it on fhd, with no extra bloatware and it's exynos variant. It also drains a lot of battery on standby like easily 15% or more overnight.

Lol bro I get 5-6 hours sot everyday with heavy usage and high brightness with WQHD

Me too. 6hrs + of SOT.
At 85% im already at an hr of sot. After that between 10-15 is another hr of sot. At 50% im near or at 4hrs of SOT.
Honestly, i think that FB app is killing ur battery. I disabled that crap n if have to use FB ill use the browser.

That's exactly what I said, people are easily getting 6 hours SOT and I'm not even on QHD.

Well I thought exynos was better then our ****ty snapdragons?....just kidding...but yeah man I'm getting 6 hours easy but I can always squeeze 7 to 8 hours on screen time....my last one was 7 hours on screen time with 1 day 14 hours plus all together....i posted my recent cycle in post your battery stats thread just for proof....and I have the highest graphic setting....i don't know man I'm rocking dark theme also to help battery as intended

did u restore any app? OR use Smart Switch? Best guess is do a factory reset if there is some bad app syncing continuously.

Yep that's what I'm thinking to do, Factory reset if the problem persists.

7hrs min Sot I get and that's with 14% battery left I think I edged to 8hr 20m but forgot to screen shot. I use qhd and brightness is pretty high too. Nothing disabled at all. Maybe try a reset and use the qhd res

I installed mine (Exynos) from scratch, only putting back on the apps I need which is not many.
I have location off unless I need it, and sometimes switch to 2G as I get better signal on that. FHD+.
With Wifi on 100% of the time, 75% brightness and all the usual suspects like Facebook, Instagram, Whatsapp and Gmail (not snapchat), I get over 8 hours screen on time. It goes around 7.5 hours if i'm using streaming services like Netflix a lot though.
That's over 2 days as well. By bedtime on the second day, I am below 10% and need to charge.

I use "Greenify" App! Now i have 5 % drain per night

You simply cannot compare like that. "He gets 5 hours SOT so why can't I".
So many variables - signal strength, wifi, bluetooth, brightness level, auto brightness, GPS, NFC, location settings, vibration settings, how long since last charge, account sync, apps installed, apps used. They all affect battery life.
So really, as long as you're getting through a full day, it shouldn't really matter what other people get.

What problem? 4 hours SOT with the stats you posted in the OP isn't a problem.

Cellular signal is a biggie when it comes to battery life. My previous house was around 3 miles from where my current house is and the cellular was weaker and I got more battery drain in fact I remember switching to 3g from 4g to help increase battery and even 2g at times.

What brightness is your screen on? I'm easily getting 6 hours of screen on time, usually with 20-30% left after a full day (14-16 hours) of use, this is with many apps that would be considered battery drainers (Kik, Whatsapp, etc) installed. You definitely should try a factory reset, since most of battery problems this type originate from a problem that can be fixed with one

I'm certainly impressed. Auto sync on all day

I'm sure you are doing something wrong, because look at my total usage time and screen on time here.
The first picture in the attachment shows the total usage time where my Galaxy S8+ only was inactive for 2 out of those 19 hours. Yes, i was using it for 17 hours out of those 19 hours in total.
But that's not all. Take a look at the 2nd picture in the attachment where it shows my insane screen on time from those 19 hours of total usage.
And the average screen on time for me now is around 8 hours which is really good. And this is also with heavy usage.
All of this is with the highest resolution, brightness at 60-70%, Wi-Fi and Mobile Data on all the time and ofc with all kinds of apps syncing in the background.

Good thing you are within the return window, you can get a different phone that suits your needs.

Im getting 9hrs on screem time at 5% left. Fhd, good signal, wifi, data, gps, 60% brightness. A mix of calls, whats app, facebook, youtube, emails, taking photos etc. Id say heavy usage as its a new phone. But thats it, give it 6 months to a year that will probaly be 30% less efficent so around 6 hrs on screen time. Im happy atm. I always also happy the first year of owning the nexus 6p but after a year id only get about 3 hrs ost.

I would suggest that is your best option as my battery life is superb. I recall owning some mobile a few years back that had rave reviews about battery life yet mine was awful. Problem wasn't the mobile but some apps I had downloaded. Factory reset etc and removed some apps and all was good. Its a pain when this happens. :highfive:
Ryland

Phew, the issue was resolved by resetting the phone and removing the second sim card since it's a dual sim variant. Now the SOT and overall performance is close to perfect. I don't know what caused it, maybe the second sim since I don't have any extra app installed besides Fbook, swiftkey or whatsapp. Thankyou all for your suggestions

HI i from India using the S8+ Exynos Variant i am also not getting the battery SOT more than 4 hours, what should i do ?

Battery Life Not On Par Anymore (Mate 9 Model MHA-L29)

Hi Everyone,
So I'm currently using the US Huawei Mate 9 (shipped from Amazon) since February and have been in love with it. One of the standout points was the battery life and screen on time. With my heavy usage (youtube, Netflix, web browsing, music via bluetooth headphones) I'd still be able to pull off about 24-26 hrs of battery life with 6-7 1/2 screen on time. However, with future updates that has been provided to the Mate 9, i'm noticing a significant decrease in battery life and screen on time.
I'm currently running the latest build (MHA-L29C567B190) with the April Security patch, the latest update for the Mate 9. My battery life has now been about 14-15 hrs and screen on time of about 3 1/2-4hrs. I've been doing the same exact stuff on my phone as previously mentioned.
Has anyone noticed the same thing?

You had what? That's insane. I can never reach that, probably in light use and I'd be pushing it. I can only reach around 4 hours of SOT in probably 15 hours of battery life. How do you reach such battery life? I've got an email account that's constantly syncing (I need to) and probably some very light Snapchat usage, but no matter what, I'll never reach your numbers. I'm impressed.

I don't even worry about battery because I have experience with repairing phones so if it ever gets to that point I'll simply replace it easily. But no i have not noticed a decrease in battery, if anything it has gotten better and better.

I think the more you use it the more the battery standby reflects your usage and will naturally be lower.

Tip. IF you used an SD card from an old phone, remove your data, FORMAT it inside the phone. then reboot the phone into recovery to format Cache ( i do it 3-4 times ) and it helped alot. something with android files not working together well. I have gone as it follows. I used spotify via BT ( not reporting BT for some reason though. GSAM knows ) MEtal for FB, no games. Texts, kik etc. no calls ( data only )

Got a new Pixel. Battery Life sucks. Is it normal?

Hello,
I've sold my S7 and bought a Pixel phone because of updates and design. It is very elegant phone and very very fast. But I've got a problem, battery life sucks seriously.
Here's some screenshots.
Because it is a new Pixel, don't think there is a faulty. I did Geekbench 4 battery benchmark and got 1700-2000 points and got over 162k Antutu.
Is it normal? Should I roll back to Nougat? Or else I will send it back and Pixel XL. I cannot afford Pixel 2 or Pixel 2 XL.

Rolling back to Nougat will do nothing good. Did you buy a new Pixel or an used one?

Same here. Bought a used Pixel 128 GB model last week that provides only 3 hours of SOT with normal usage (browsing, music, videos).
It's on Oreo 8.1 with latest security patch and NFC, location turned off. Still no good.

Excluding gaming, for chrome browsing, reddit, YouTube and Instagram plus a few other misc apps, I get approximately 3.5 hours on data and 4+ on wifi. Rma brand new set from Oct 17.
SD 820 is not really known for its battery efficiency vs the 835.

Your first 5 apps listed are using about 50% of your battery. On my pixel XL I could easily get 8 sot if I wanted. You should look for ways to reduce battery useage, like battery optimization and limiting power to apps not in use. What does the acc battery app say your battery health is? My battery preformed better after installed dp2, but was very good before installing dp2, it just got better.

I've got 100% battery health. Now I get 3-4 SOT, 10-14 hours standby. It is not the best, but it's ok.
How can you limit power to apps not in use? You mean deactivating background process? I did that already.

That doesn't sound particularly bad. I normally end a day on about 20-30% with 3 hours of screen time or so. I know it's a bit of a cliche, but it really is hard to compare two setups like for like. Even SOT is not a great measure because if you watch a 2 hour downloaded movie on Netflix with low screen brightness (for example) that will consume A LOT less power than playing a game or browsing the web for 2 hours... but both will just show on battery stats the same. Let's not get into whether you are a user of Google location services (for things like Google fit or Assistant etc), or streaming Podcasts over bluetooth...
Some people have already reported better battery life on Android P - though I take that with a slight pinch of salt as every Android release supposedly did that already.
