I recently acquired an AT&T Tilt for myself and an 8525 (HERM100) for my wife. Since getting the 8525 there were issues with the battery being depleted quicker than one would generally expect - the battery going from 100% to 0% in less than 3 hours with most of the time spent in an idle state.
I figured it might be a software issue and decided to look for a ROM that is reasonably power efficient. Using the WM6.1 BENCHMARKS thread I decided on loading PDACornerPro V27 RBSN 3G. Additionally I disabled 3G connectivity as we don't have data plans for the devices and have no need to run the more power hungry radios. I also diabled all the device's data connections using Modaco NoData so nothing would be triggered inadvertanly. I also ran the Battlog utility to get a record of general power consumption; idling w/ the screen dimmed/off at about 30ma, while running application it would top out at about 170ma. I was satisfied with this improvement as with 'normal' usage the phone could easily last the majority of the day without needing a charge (which was the goal), so I gave the device back to my wife to use again. The device was left idle for the remainder of the night, by morning it was dead. I checked the battlog utility's log and found that shortly after leaving the device to idle for the night it's power consumption jumped up to around 470ma, depleting the battery very quickly.
I verified that 3G was still off and that there were no unnecessary processes or applicaitons running in the background. No matter what I did the power consumption remained around 360 - 470ma. I finally decided to give it a rest and I pulled the battery from the 8525 and left it alone for about an hour (gave me some time to relax from the fustration). When I returned I reinstalled the battery and powered up the device, I checked Comm Manager and found 3G on again; I turned it off and I checked the Battlog utility and found that the power usage levels returned to the aformentioned 30 - 170ma. The following day this happened again - same jump in to the 400+ma range and after having the battery out for ~20 minutes power usage returned to normal; the only difference this time was that 3G had not inadvertanly been reinabled.
Any ideas on what would trigger the dramitic increase in power usage (an how one might prevent it) and why letting the phone sit in a powerless state for ~20 minutes would correct it?
Recap of the device:
ATT 8525 (HERM100)
ROM: PDACornerPro V27 RBSN 3G
Radio: 1.54.07.00 (Stock)
SPL: Olipro 2.30
Battery: HERM160 (3.7VDC, 1300mAh) & HERM161 (3.7VDC, 1350mAh) *tested with both batteries, same results.
Thanks for any insight you can provide. Attached is a zip with Battlog's log file of the first occurence of this problem in text format as well as in an xls file.
Ideas from a non expert
Well, i did experience something similliar with a touch pro. Suddenly battery consumption increases like hell. I believe it happens, when changing cells of your provider. E.g. the device switches between GPRS and 3G back and force, because you are just in between. So, maybe this activates the SIM card - which would consume more power - I guess. I am not an expert for this. But I could observe sudden massive power drains when moving in a train or even in my flat, where one side is more GPRS and the other more 3G. You can watch e.g. by using http://www.commmgrpro.com/. There is a "save battery" mode. Ok. But this are just my non techie thoughts. Pls. post, if you got a solution.
Hey I have exactly the same problem as you do. I just recently bought this phone on ebay, and I charged it full and left it idle for 2 days. I come back and the battery is completely drained. Also, the 3g icon keeps showing up. All I hope for is that this isnt a hardware problem.
Same for me battery drains far too quick, maybe the batteries are slowly dieing, i have seen the other more powerful batteries what last a lot longer, i think my option is to ebay for a battery of twice the power. There is just so much going on with all the tech on the pda's i suppose these batteries just can't hack it. Like i say short life length on them.
Hello guys recent p8 lite owner here I am having huge issues with battery life, I charged it to 100% and went to sleep, data was off wifi off nfc off basically nothing was on and when I woke up 7 hours later battery is at 75% with 0 Screen on time.. even when data is off 3g sign shows above and most of my battery goes to the mobile signal according to the graph..
I only get about 90 minutes of screen on time per day, any tips on improving this? I have auto-sync on does it eat up lot of the battery life?
also is there a way for it to use 2g signals for browsing to save battery... should be able to switch o 3g,4g for high intensive stuff like youtube.. im assuming if I use 2g my standby time will improve a lot.
Thanks
I use the Optimization button and Ultra Battery mode quite a bit and can usually get two days on a charge without much trouble. I've had the phone since June, and I don't think the battery has ever lasted less than a day (but I'm not a real heavy user).
In Ultra Battery mode, the battery drains just a bit overnight, maybe 3%. I also use Ultra Battery during the day when I'm at the computer and don't need the phone for anything besides calls and texts.
Early on, I disabled quite a few apps that I never use, and that has probably helped the cause.
I've always got 4G turned on (except when it shuts off on its own because of Ultra Battery or WiFi ).
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.

Try wiping cache and still if it doesn't work go for a reset and it should be ok

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 first sim is Jio sim so my data is also on 1st sim. for calls and data both i use jio. and my 2nd sim is vodafone.
I'm wondering if any of the updates fixes this. I'm still on January security patch...
I have same and dont have found any solution to solve this. i bought my phone only a few days ago and i use only one sim card

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???
I used to have this problem where my cell/mobile standby would be around 18% after 24 hours. Thats a lot of drain. I looked in several places for a solution but didn't find any. I even did a factory reset but still had the problem.
So I shifted my sim into the sim slot 2 and the problem was gone. Right now I have used the phone for 24 hours and the cell/mobile standby is at 8%
So that fixes that
eventhough the cell/mobile standby shows up in my battery stats on first place I dont have the feeling that it really consumes that much energy that it shows
my SOT is still great 6h+ with high usage so I guess it is a display error

Really? How much is your drain due to cell standby after 24 hours? Or even 18 or so hours.
Shifting my sim into sim slot 2 did not fix it.
Does anybody know how to fix it?
Try switching off wifi scanning and Bluetooth scanning under location settings. Also disable location history. It gives a better mobile standby. But even this is not a stable measure to stop abnormal battery drain by standby. Even I suffer from the same issue.
I believe its a software bug. Most people say they get good battery. Even i do. But I just can't digest the fact that mobile standby is using up quarter of the charge (250-300mAh in 3 hours) when the standby in my old Moto G2 uses negligible battery (60mAh in 13 hours).
Hello.
I've read a few threads on here and elsewhere that address the general issue but not this precise situation.
Background - S8 received back from repair. Factory reset as standard. Clean installed usual apps.
I noticed over the following week very poor battery life compared to pre-repair. Another S8 in household, we checked every setting was the same throughout. Also confirmed massive battery drain difference overnight. I was convinced the repair shop had sent me a refurb handset (or refurb internal battery). Checked IMEI - same handset at least.
Installed GSAM to monitor overnight. Phone Radio heaviest user by a mile. I'll upload the photos later but typically 3% - 6% per hour. Second night I turned absolutely every setting off including WiFi, Mobile Data, Sync, but left network signal on for receiving calls. Exactly the same heavy battery drain on Phone Radio was recorded. By now I'm thinking my sim card is hunting between cell towers or something is not right with the syncing of my Vodafone account/sim card. Third night I turn every setting off and then completely remove the sim card and sd card (signal strength bars still show due to internal chip for emergency numbers). Wake up to even heavier usage, nearly 7% per hour drain due to Phone Radio.
What is the internal phone radio/cell chip getting up to at night, and why now after repair? Any help greatly appreciated.
Funny that you say that. Insurance claim with AT&T and Asurion gave me 8+ like I had. New device is doing the same thing your saying and I didn't have that problem with my old phone. I believe my replacement is a refurbished phone.
Why isn't there any update to that? I suspect this is a planned obsolescence scheme to push you to buy a new smartphone since there's no reason for that...
