Hey Guys,
I've gotten my Moto G5 Plus about a week ago and I'm loving it so far. However, I'm having a bit mediocre battery life. I only manage to get about 4 hours of screen on time with very light usage (mainly whatsapp and a bit of reddit). So I went looking for what this might be causing. In the battery stats it's showing a 29% usage for Cell standby, with a 99% time without signal. I'm only using one of the two sim slots currently and I have cellular data turned off. It is also almost always showing full bars for the sim card i'm actually using, the other is turned off in the settings. I'm used to having the screen be the biggest battery drain and cell standby being around 5% on my Moto G2 running with the same simcard. I've already tried reinserting the sim/sd card tray and rebooting a couple times, both of which didn't fix the problem. Do you guys have any idea what's going on?
Thanks!

PS: I can't post the pictures because I'm new on XDA but it shows the cellular network signal being entirely red, the screen at 5% battery usage and cell standby on 29% with the 99% time without signal.
Most reviewers are reporting GREAT battery life with this phone.
Is the phone rooted? Did you run Wakelock dectector?
I assume you have turned the phone off and back on?
Have you verified that your APN settings are correct?
I would open a ticket with support unless you've already put a custom ROM.
The phone is not rooted and yeah I have rebooted it a couple times. I'm going to try running wakelock detector and see what it says. I have however turned on the other sim which seems to make Cell standby use normal ammounts of battery which is strange.

The same thing happening to me also. My Moto G5 Plus was at 19% at night and at morning I saw as 8% remaining. Before that, It decreased around 22% battery during night. Mobile data, Wifi everything was kept off. When I checked the battery stats today it showed cell standby on 2nd number draining the most battery. What to do for it? If anyone has any solution please let me know.

It seems that on my phone the only thing this is happening is when I turn one of the sim cards off in the settings. I've been running both sims at standby since yesterday and de battery usage is currently at 6% for Cell standby. The time without signal has also decreased to 0%. You might want to try to keep both sims enabled and see if that helps.

Just out of curiosity are you also running a dual sim version of the G5 Plus? And if you are, are you running with both enabled or just having one of them enabled at a time?

I think I found the issue/solution! When you do the dual sim setup and get to choose the data sim, I picked that as my second sim as I don't use data often. However, while having the second sim enabled it seems to always keep looking for a signal. Which it obviously can't find because the sim is disabled. This of course leads to high battery usage. Changing the data sim to the first sim that's actually enabled seems to resolve this issue.
I, too, have issues with cell standby draining battery. For me this seems to be an issue with LTE / 4G.
The problem occurs as soon as I activate LTE/4G on the data sim card. It also happens with only one SIM in the phone. If I switch to 3G only, the drain stops.
So:
- With only 3G enabled and wifi connected, all apps installed, syncing etc. I get a huge standby time of ~13 days.
- If I enable the LTE while being connected to wifi, standby time remains good at first.
- As soon as mobile data is first used (e.g. shortly disable wifi so LTE data is used), huge battery drain occurs (about only a day of standby time) everything else as above.
This happens even if wifi is used afterwards. Once connected / mobile data used (with LTE), battery drain occurs. Toggling enhanced LTE services doesn't make a difference (I had it enabled inititally but also tested with it disabled as my provider doesn't support VoLTE or IMS messaging with this phone). Switching to 3G stops the drain.
This is seems to be a bug in Moto G5 Plus firmware and/or baseband. Note that adb logcat doesn't show anything out of the ordinary.
LTE signal is excellent at my location and none of my other phones have such a drain with LTE using the same SIM card.
When I turned it back on today it started having the same drain again. Even though I didn't change any settings or anything, just rebooting. This definitely seems like a software problem, however when I posted on the motorola/lenovo forum about it they just shook it of as if I have bad signal reception...
Hey all.
I am having this exact same problem on the XT1685 Dual-SIM, 3GB/32GB model, using only one SIM card. Mobile standby always drains the battery - during day and night, regardless of which SIM slot is used, and even when there's no SIM card at all! Mobile network coverage is excellent in my area, and despite that, mobile standby ends up eating 1000mAh (25-30%) per charge.
Anyone else experiencing the same issue?

My UK phone updated to the May security patch recently and the phone loses about 1% every 4 hours overnight now.
How? i still facing this issue... any solution???
After switching service provider, and of course change from SIM card, I noticed a huge battery drain, sometimes over 10% per hour when the phone is almost idle. Battery life WAS very good, but now it's quite bad.
I cannot find anything about this, except for some old articles suggesting a faulty SIM card. I don't have other problems. Any suggestions? Anyone who recognizes this problem?
Battery stats is showing Android System (26%) and Phone Idle (20%) as most important battery draining apps.

It could be the SIM card or it could be the provider. Do you have less bars/signal with the new provider? The only thing that generally causes an idle phone to drain like that is if it's constantly searching to try and pick up a signal. Since the phone was fine before the switch I am willing to bet it's the SIM card. Years ago (LTE was still fairly new) when getting a new phone I had to go through three of them before life was good again. The one that came with the phone was old and outdated so it couldn't pick up a 4G LTE signal. I then went to a store location and they swapped out the SIM card but as luck would have it the ones they had on hand were outdated too. It wasn't until the main office mailed me one that life was all good again.
So yeah try a new SIM card, may want to just call and have them mail you one. Hopefully that helps. If not check what radio bands your new provider uses and compare that to the ones supported on the phone.
I have a Canadian Galaxy S8 , so the one with Snapdragon.
I factory reset the phone, with nothing installed and the battery drain is 4-7% per hour with screen off. There is nothing installed on it. On my Galaxy s7 edge, the battery drain was 0.5-0.8% per hour when on standby.
Is this normal? My S7 had Exynos processor.
Even on airplane mode it's at 4% per hour on standby....
Anyone has similiar issues?
Thank you

Brand new S8+ (canadian model) battery is OUTSTANDING. ridiculously almost.
However, resolution is half-way - makes a huge impact and is indistinguishable. In fact the phone is snappier with the lower resolutions.
Alternatively, you can get legitimate battery drain you can't account for when you have poor WiFI and LTE signal - so this could be the cause of your battery drain.
Turn on airplane mode and remove the SIM and if the battery drain stops you have an idea.
I also have the resolution midway and I ran it on air plane mode and still 4%+. I'll remove the simcard and check. I'll also remove the external card.
When I removed the simcard the battery drain was 1-2% per hour. As soon as a I put the sim card, it drains more than 4%+ per hour.
Then I put the simcard on my S7 Exynos, in the same location, drain was less than 1% per hour. The S7 has 300+ apps installed while the S8 is fresh from factory reset.
I bought the s8 from someone on Kijiji, then the idiot who sold the phone had created a fraudulent account, so my phone was blacklisted (He even gave me the bill). So I got stuck with a black listed phone. So I changed the imei (using some service) and it's working now.
I'm not sure if changing the imei has caused this battery drain
I genereated a bugreport, but it can't be read google historian.

I have used better battery stats and here is a dump and screenshots after 3.5 hours. There is nothing alarming (no wakelocks) yet it is draining 3.5% + / hour, even if the phone is in deep sleep and nothing is syncing. Location and bluetooth are off too..

Here are the battery stats (Attachment failed in previous post).
I really think the phone is defective. Here are some stats after few more hours. I will go a Samsung repair shop, I hope that they can fix it.
Anyone with Canadian galaxy s8 (Bell) has this issue? I can't figure out the problem .

If you look at the zip file i attached, it has betterybatterystats and some screenshots. There is nothing alarming, phone is in deep sleep most of the time. I sent the phone to Samsung today.
System panel shows what is actually using your battery and how much of it, is very useful.
Yes, I would say you have a defective phone. My S8 and several others I know of have extraordinary battery life. We find it one of the best things about the phone.
Same issue after repair!
I got the phone back from Samsung, they said they replaced antenna and re-calibrated motherboard and I still have the same issue! I used SystemPanel2 and my battery drain is in "unaccounted". There is no significant wakelock. Look at attached files.
Anyone has this issue?
I have the same issue. My phone barely lasts through the day.

The image shows the phone was without signal for some time which was about 32% and it will consume power. Don't know the reason behind this, but if phone really had no signal for a long time, then be in another place where there is a good signal and test there. I have seen few times with my old Moto X, that sometimes after using internet via mobile network(without wifi), the connecting would somehow still be open and it would consume battery and the way to fix this, I had to restart the phone.

best bet do a factory reset and see if it still persists
Same happens to me too. Yesterday I went outside my house and traveling in the city - my battery went from 100% to 43% in 6h40min. I had SOT only 1h. I am wondering if something related to GPS is killing the battery as it always drain very fast if i am moving - but in the other hand it seems that phone radio is draining also the battery a lot. Any advices what could I do?

Cell standby drains too much battery
I'm using Galaxy S8 Exynos Version (Dual Sim). Facing this cell standby extreme battery drain issue recently. I have tried several options like- reset network settings, restart / power off-on, factory reset and wipe cache partition to see if the problem goes away or not. These things can solve the problem only for 2-3 days. Then after that same cell standby battery drain occurs again. The only thing left is to hard reset. But I don't think this will solve the problem either. These are not the permanent solution. When I first got the phone this problem was not there. For the last 2-3 weeks I have been facing this issue and it is bothering me a lot coz my battery drains too much even when i'm not using my phone. I really need a solid solution for this. Can anybody help? And I hope Samsung will address this issue and solve it asap.
I think cell standby is the worst problem in the S8. It really kills battery. It can make your phone drop 2% per hour.
Same issue here. Didn't have this issue before the latest two updates. Before I had 6-7 SoT and now barely 2-3 hours.
yes, this issue was not pronounced before the latest updates (one or two as mentioned)
Same thing here. After the last update there is a battery problem with standby. Hope they fix it with next release.
same with my s8+ dual exynos
Hi,
My Samsung S8 since last upgrade to Oreo was a complete disaster. Just to be clear battery life during Android Nougat was good and it was the first thing ive noticed that samsung completely stepped up their game since their battery disaster on their certain phone model. Battery life would run at least from a day to 2 before recharging. Ive noticed there are other threads similar to these so i knew im not the only one affected, my colleagues also experience similar issues since upgrading to oreo so this is not something isolated to my s8 phone.
Few key points that ive noticed since upgrading to oreo:
1. Going to settings then battery usage. Screen would be the foremost battery hog at 26%, followed by Android System at 13%, then Device Idle at 9-8%. Cell Standby and Android OS remains normal.
2. Go to Settings then App. Ive noticed by checking each one of the apps that beaming services, device maintenance, settings, gear vr services were among the ones that took up most of the battery usage this is excluding system apps like AASAservice, etc.
3. Go to settings then data usage. The Android OS is sending or receiving 100MB of data (still counting). I wanted to know what are these data that is worth 100MB.
4. Device easily gets hot even light use of facebook, ig or 7 minutes of youtube video.
5. It sometimes restart, this is rare but ive noticed it since fingerprint cannot be used initially when there's a restart.
Now what ive done so far:
1. Cleared partition cache by holding bixby btn, volume up and power.
2. Disabling unused apps, even certain bixby services, etc.
3. Went to developer option and disable always on mobile data.
4. Factory reset device hoping it would go back to nougat but it did not. With a mint condition reset, it still drain too much battery. (without any third part apps or data restore)
5. Called up samsung customer service but was told to go to service center. Went to service center they check the ASOC of battery (which i think is unrelated) and according to them reprogram oreo. which did not help. wasted my time.
Now what is the implication?
1. I need to charge my phone at LEAST twice a day.
2. It heats up the phone which would definitely have negative impact on the longevity of this device one way or another.
3. It drains too much battery, with the amount of charge discharge multiplied at least by 2, this will literally messed up the battery life in the long run.
4. Im currently using 2 phones and my samsung s5 which is a 4 year old phone had better battery life. lol. Since in just 3 hours it consume almost 40% of battery.
There are tons of related post like these on different forums and on reddit but i surmise i should dig more on this problem before writing a more concrete post. At this point, i can only see 2 remaining options: 1. There is a step online that would revert the OS back to nougat but this would involved third party apps like odin, there are risk involved like phone brick, etc. Im not sure if it will void the warranty. OR i can just wait for a patch from samsung.
Now SAMSUNG NEED TO FIX THIS ASAP or provide us a way to revert back to nougat. With the s9 just available at the market, this terrible oreo release could not come at better time. I know there are several issues like the battery issues with their previous note model and Apples intentionally slowing down their phone, Samsung got to fix this fast before this issue becomes a blowout and many people will start to notice.
There are several threads about this: https://forum.xda-developers.com/galaxy-s8/help/to-to-fix-battery-drainoreo-t3771716

Man, i´m totaly on same boat!
In CRC7, i'm experiencing terrible battery life. Max 2.00 to 2.30 Screen on time in one charge. Now, for the first time, i have to recharge my phone befoure dinner.
Wifi , Bluetooth, Aod On, location history Off.
It´s the worst experience on any phone that i had in the past.
Like you, already disabled some apps, clear cache and already done a fresh install. Nothing works, nothing improved my battery.
I´m thinking send it to warranty, but it´s probaly not worth the time...
Maybe it´s time to forget about Samsung phone and move on. P20, or even iPhone X...
After updating to OREO and updating all galaxy apps, "beaming service" was draining my battery (67% of the battery actually). After uninstalling the updates on beaming service, the phone seems fine now. Maybe uninstalling the updates of which apps are draining the battery could help you guys as well.

Hello !
I've been s8 for three months and I've never had any particular problems, I've upgraded to CRC7 (second update of Oreo) and I've already got twice the phone with a flat battery:
last week in the morning I found it at 1% from 35% the night before (during the night only the gsm network was active, everything else off); when in doubt I did a factory data reset by installing only minimal applications (FB, whatsup and little else) and I installed the Accubattery application to monitor the battery.
Last night put away (active gsm only) at 65% of residual charge and this morning after 10 hours it was 5%: 60% of charge consumed in one night.
Android does not report any abnormal consumption of any application .... it seems an anomalous battery drain
I enclose battery data screenshots; is not that the new Oreo update is buggy? or could the battery or the phone power circuit or the radio part that consume excessively might have a problem? Before bringing it to service I wanted your opinion and in case I wanted to try to put back the CRB7 version of Oreo .... how do I do it? do I lose the guarantee in this case?

I have the exact same problem as you and many others. I have tried various things to solve it and I concluded on that the modem firmware has a serious bug . airplane mode consumes more battery than on cellular. To make sure we are talking about the same thing please try removing your SIM card and let it all night . By the morning you have to be -2% of the battery . With the SIM inside now you have to drain 15-20% . If thats the case for you , you make sure that its not a faulty device and there is no drain from your setup (like an application draining etc .. in this case factory reset should fix it).
Cinfirm your findings and lets hope they will release update soon.

I have tried various things to solve it and I concluded on that the modem firmware has a serious bug . airplane mode consumes more battery than on cellular. To make sure we are talking about the same thing please try removing your SIM card and let it all night . By the morning you have to be -2% of the battery . With the SIM inside now you have to drain 15-20% . If thats the case for you , you make sure that its not a faulty device and there is no drain from your setup (like an application draining etc .. in this case factory reset should fix it).
Cinfirm your findings and lets hope they will release update soon.

he doesn't do it every night, but random : in a week it happened twice
It's not in airplane mode, modem is switched on only for phone line (LTE off) ; I already tried two factory reset
Yours is affected only in airplane mode ?
Tonight , my s8 have to drain 60 % in 9 hours !

It drains in general but while in cellular it's difficult to distinguish if it's a bug or bad signal . Each ones phone may consume different amounts of energy depending on coverage etc. But in airplane mode you can be sure it's a bug because antenna transmission should be off and therefore not consuming energy . Just try as I said just to be sure we have the same issue . One night with airplane mode and SIM card in and another night airplane without SIM. You should see great difference .

Tonight ( gsm on ) have no drain : 0,3 % / h. ( 3 % in 10 hours ).
if it is faulty the battery should always do it?
Did you try to see if it drains, leaving the radio part active?

This will not help determine the bug because as I told you it's signal dependant. It's 3% in 10 hours because you probably had good signal . Else it could be more and even if you contact a service they will say it's not a bug but the signal . Anyway if you were with data on and 4g seems more than fine to me . Now if you try this night airplane mode for 10 hours it could drop 15-20% ... is this reasonable ?

in airplane mode is a bug, but a 60% night-time consumption with active gsm?
0.3% / h. the device was in the same position the night before when it consumed 60% in 9 hours

Your case seems more like a random application wakelock . Did you do a reboot between the 2 nights?
To distinguish better the cause of the drain , when you see an abnormal consumption try removing your SIM card for a while . If this fix the drain it's the buggy modem/radio firmware ...
