[Q] Battery drain when idle

Hey guys,
Wanted to know what your experiences with battery life were like.
When I go to sleep, I switch off wifi, bluetooth and data. When I woke up after 8 hours, the phone had lost 7%. Seems to be quite a high number for it being dormant.
In battery settings, the 'Phone Idle' option was top of the list for battery drain.
Anyone else experience battery drain here? What have you done to help improve it?
Cheers.

What's your reception like?

Don't you need root to use better battery stats? Phone hasn't been rooted yet.
Signal strength is decent, not full bars, but close to it.
My last 2 phones (N5 and OPO) have had really good drain whilst dormant, so puzzling as to why this one is playing up!

My vzw was similar. About 10 hours of no use and was down to single digits.
Did a factory reset and it was better... Teach it who's boss...

Last night my phone was off the charger, at 100% to begin with, at around 2 am. I checked it at 6 am and I was still at 100%. For me, idle power usage has been very low.

Ya you need root. Goto WiFi settings then advanced and see if the 2nd option is on, (its something like apps scan for network even if its off) turn that off. If you want to stop Google play services from waking phone from privacy guard that helps a lot too.

The other thing I did (not sure if it is related) was to disable all the VZW apps and processes. WHen I did that I only lost 13% when left over night and I was down to a respectable 73% after a full day of work (though I intentionally did not use my phone much during that time)

This phone sleeps unbelievably well, better than any other phone I've owned. It flatlines very nicely

I did not manage to factory reset the phone overnight, but I did notice that the battery life whilst sleeping was incredible.
Over an 8 hour sleep, I had dropped 2% battery life. I switch data and wifi off when I go to bed. Now I'll keep an eye on SOT. Hoping to hit the 4hr mark. On my first few days, I got 2.5 hrs.

Even I Am experiencing same problem. Any one plz help

I have the International H815 and I have the same problem. Battery drains too much on idle. When I look the battery stats the Doze mode rarely kick ins. Location is off Bluetooth off and I'm on wifi. When Doze works I have really good battery and I can hit 4h of SoT when not I can barely hit 2.5h of SoT. This must be some kind of bug. Phone does not goes to sleep and Doze rarely kicks in.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the ZTE Axon 7 before depleting the battery.
Then, drop a comment if you have anything to add!

One of the better SOT phones I've owned since coming from smaller 4.5 inch screens. I easily get 4 hours on a long day (16 -18 hours off the charger). I watched 2.5 hour movie the other day and did some more stuff. In 8 hours, I had over 5 hours of SOT with 47% battery left.

I don't like gsam because it doesn't read the SOT from the system. It records it's own stats.

GSam battery monitor allows you to see the stock android battery stats and screen on time from there by going to the menu on the bottom right, clicking more and then Battery Use - Built In. If there is an easier way to get to stock android battery stats, I'd love to know.

What settings do you guys have setup? My battery is down to 27% after only 8.5 hours off the charger and not much video watching. How do you have your phone setup concerning gestures and everything? I use the fingerprint unlock and the double tap feature and so far I am not impressed with the battery.

What settings are you using? I'm barely getting10hrs of battery

Nothing special, really? It's basically stock, I just disabled some stock apps: Browser, calendar, stock email, Gmail, Hangouts, and stock messaging. Everything else is left alone.... I even installed the actual Facebook app (aka: battery eater) for the first time in a few years, since my battery can keep up now.

No screen on time. I am in an area where I get no service and was using WiFi, so today I turned on Airplane mode and then WiFi and it seems to work a lot better. though I still need to investigate is battery drain is bad when using the phone in normal service area.

Sounds like wakelocks to me

This is the best phone I've owned in terms of battery life. With nova launcher and using nova's battery widget I can see my SOT. I average 5:30 which is alot for me. I have gotten as much as 6:40! This is all usually over 12-28 hrs. The phone is just phenomenal, just wish the camera was better.

I would believe it. I got about 5 hours in my last run. What I think ate up about 20% was listening to music through the speakers.. The phone drained faster than normal Witt the speakers on at max volume.. Which makes sense and is 5000% tolerable because how amazing they sound.
Furthermore, if I could get some stronger cell phone signal, that would help with screen on time too. I never have no signal, but I never see over two bars of signal either.

Sorry about double post.. Forgot to include second one..

Ok, I thought this was a battery beast but I think I was wrong. I don't expect any phone's battery indicator to be totally accurate but I've noticed that if I top the A7 up a little the battery doesn't drain *at all* for a long time. I've been letting it go down to 30% then topping it up to 40% where it stays without moving even while I'm streaming music and surfing for half an hour. Fishy.
I thought that as I was on about 3:30 sot at 40% I'd let it go down further to see if it would reach 5 hours. Three charging cycles in a row the phone has hit 19% and then reported that it's empty and shut down.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the ZTE Axon 7's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

Left it off the charger last night for 7 hours - batter only drained 3-4%.

With the data off I lost 1% in 8 hours, with the data on about 15% in 8 hours (this is probably because of the notifications from AA and other apps )

Only lost 1% last night with data and wifi on, and all apps closed.

I lose 20-30% battery every night and I have yet to test how long it takes to charge from 0%, but it takes about an hour to charge back up to 100% in the morning. That's using the quick charger included. I'm thinking I may have a defective battery. I just unlocked my bootloader and rooted yesterday so looks like I won't be able to exchange it. The only reason I root is for AdAway. I haven't had my phone a week yet and had been using Netguard to block ads. I thought it was that, that was eating my battery but apparently not. No difference using AdAway. Woke up to 82% this morning.

Thanks! Could you sort on wakelock amount? Not sure what it's called precisely, but it should put the Google App on top of the apps shown in your screenshot (it focusses on the x526).

Do you mean sorting it so the app that's causing the most drain is at the top? If so that's what I've done for that screen shot.

It's now sorted by duration. It would be more interesting to see what apps do the most number of wakelocks (and thus preventing your device from going into deep sleep).
So, for example, from your screenshot we can see that 'Phone' did one request (x1) for a wakelock. But your Google App did it 526 times (x526). Try to find the option to sort on that information.

The picture I posted was the CPU Wakelock option. I switched to wakeup triggers and the Google App shows 77 and there's nothing in the screen wakelock option.

So I put my phone back to stock (relock bootloader, replace TWRP with stock recovery) because I was planning on returning it. It wasn't only the battery life I wasn't impressed with. It was the overall experience. I found the phone super laggy. When I put it back to stock it miraculously came to life. Battery life is great (only lost 2% overnight compared to 20-30% previously) and it seems much snappier. I'm actually really happy with it now. Even as I said before I unlocked the bootloader and rooted I had the battery issue and it still continued after rooting. I ordered a Pixel XL which I should be receiving tomorrow. I might end up sending it back and keeping my ZTE which is basically half the price. Also I would be charged a restocking fee of $78 plus I have to pay shipping back. There's pretty well $100 gone. I'm quite impressed now with the Axon 7 and I'm pretty sure I will be keeping it.

Don't know if you're still having this problem - I had the same thing for the first few days of having the phone. Accuwewther seemed to be using a lot of battery so I deleted it and ever since then drain had been normal (1-2% per hour when idle, compared with 8-10% with the weather app installed.)
For anyone else having battery issues, try th e above and see if it helps!

i tunr off my phone. and the battery still gets empty by itself. does anbody has the same problem.

I'm really pleased with this phone, the battery drain overnight is non existent:

on nB09 is about 0,5%/h after 1st charge,
after 2nd is is about 1%/3h

Huge decline in standby time.

For the last 2 days I've been seeing a huge decline in standby time. Last night I went to bed at 100%. A little more than 6 hours later and I was down to 88%
The battery settings shows no apps using battery and the full device usage only shows Android System, Phone Idle, Android OS and Mobile network standby.
GSam shows 70% of battery for app usage but won't say which apps and as already mentioned the battery settings shows no apps using battery.
I also haven't installed any new apps in the last two days either. I even rebooted my phone last night right before I unplugged it when I went to bed.
I usually lost like 2% over 7-8 hours of standby. Now I'm losing like 12% in just over 6 hours of standby.
That's a standby power usage increase of like 6x for what seems like no reason.
Any ideas of what could be going on?

1%/hr is common and yours is 2%/hr. (2x) Repeat in safe mode to rule out one of your user apps.

In my experience 1%/hr while in standby not being touched at all(doze) is NOT common. It's usually like 0.333% for me. Your claim of 1%/hr would result in an 8% drain in 8 hours. I usually see 2-3% over 8 hours.
I will try to remember to use safe mode when I go to sleep tonight but since I haven't installed any new apps in the last several days and the battery stats don't mention any apps using a lot of battery I don't expect much difference.

FB app is the devil!
When on the 6P I was losing a ton of batt life after installing the FB app.
I uninstalled it and used a bookmark on my home screen to access FB via browser, and my batt life immediately jumped back to where it was.
FaceBook app or 25% less batt life? See ya FB!
As far as the OP question: I'd suspect something is going on in the background as I have two apps that are recognized as using battery in the background and I only lose 3-5% overnight.
Could you have changed a setting and forgotten about it (GPS, WiFi scanning, sync, etc,) or is it possible your service/signal has been really poor the last few days?
Good luck figuring it out!

FB was the one that really stood out as a huge batt life killer. Any app that's constantly checking for and sending notifications will likely put a good dent in your batt life as well.
Sorry I couldn't be more specific.

there are also a decent bit of ram/storage "cleaner" apps that besides being useless drain your battery

S20 serious battery drain issue

My s20 Exynos is draining 1 percentage battery every 3 minutes when screen is on. Location , bluetooth, aod and all are off including Bixby. I'm using single sim and signal is very good. Using wifi for data. Can't understand what is causing battery drain.
Is my battery fault? I purchased just 2 weeks ago and it's really frustrating me.

Thanks a lot for your list. I'm going to do factory reset and check how it improves. Its a big pain moving all files to pc and copying back. I'll update my status in some days sure. My sot is very bad now, getting 3 hours only

For the moment it's normal let the phone learn your habits and your usage do the update and do 2 or 3 full cycle charge (20 to 100%) after that it will be good if not you can ask a replacement because you have a damaged product

I had similar issue on my S 20 Ultra but even worse. After update to One UI 2.5 I had huge battery drain,overheating, can not even reach 120hz and had lags every 10 secconds no matter what I was doing.
I tried to: Wipe cache did not help, new function apps optimizer did not help, restart did not help.
I found that new "design" Edge panel ate approx 8% of battery over the night so I disabled it ,restarted my phone and everything went back to normal.
I never had such a problems with any phone in the past. This is embarrassing!
Hope this will work for you too!

May I know how did you know edge panel took 8%?
Because battery care does not show system apps power consumption. Accubattery and gsm battery also did not show system apps power consumption.
I struck on finding which one is causing this huge power consumption.

settings -> device care -> battery -> battery usage-> edge screen
edge panel is a part of edge screen "app" which I can normaly see in the list.

I've checked it. It shows only 1% was used for edge screen. Samsung has hidden the feature of showing system usage like screen , wifi, cell radio signals etc.
Why the hell they did this. If it is available we can easily find which one is causing issue

Any ideas?

Try running med power saving as a test, see what your drain is then.
What is showing as your biggest battery drainer? You can try grabbing galaxy labs and seeing what's going on via battery tracker. You can find galaxy labs in the galaxy store, if it's not there then someone posted the apks in the apps forum as it's only available in some regions. . It gives you a little more granular visibility in batt usage.

check out gsam battery monitor from google play store. You will need to enable permissions to allow it to collect enhanced stats. This is done via ADB ( Android Debug Bridge), which is quite a simple process. The app walks you through enabling it step by step. This may help to identify what is going on. I can't remember how much detail it gives on system processes. But it is free, so worth a try

Newest update has also tanked my battery. Have a S20 snapdragon.

welcome to the world of exynos

see my post #311 here https://forum.xda-developers.com/galaxy-s20/review/screen-time-t4010447/page32 it may assist with some options to tweak to help with your drain. I got the new update a few days ago and my battery use is still fine, around 3% drain overnight for 8 hours.

Battery and Lag
I have the S20+ and when the new software BTH5 was installed...it was a nightmare ...huge drain and lag was terrible...I wiped cache no difference then factory reset which I hate doing due to the reinstall........however it is absolutely perfect having done that. hope that helps

Install Better battery stats from plays store, give it all the required permissions, do a full cycle and check what is draining your battery there. It's a very good app, perfect for troubleshooting battery problems.

Try running med power saving as a test, see what your drain is then.
What is showing as your biggest battery drainer? You can try grabbing galaxy labs and seeing what's going on via battery tracker. You can find galaxy labs in the galaxy store, if it's not there then someone posted the apks in the apps forum as it's only available in some regions. . It gives you a little more granular visibility in batt usage.

There is no app causing battery drain because I have put all apps in deep sleep mode. Accubattery and Samsung labs battery tracker showing apps power consumption only and not hardware power consumption.
I've charged for 92% and it went to 82% in half an hour of sot and 2 hours of screen off.
This is very annoying me to find out where is the problem

No issue here. Do a factory reset may help
