Severe idle battery drain - OnePlus 7T Pro (Regular & McLaren) Q & A

I got the phone yesterday, I set it up but haven't transferred my sim yet but I've noticed that the battery drain when idle is quite severe. I've only done the OnePlus transfer. And WiFi has always been on. But this battery drain is not got at all.
Can anyone please advise how to improve it. In fact , I had put it on battery saver mode and it still drained. For example at 10% decrease over 7 hours is not good. I expect a 1-2 % decrease overnight.

Try uninstalling OnePlus Switch. You don't need it if you've set up your device already.

This is just how this phone works, and I recommend you to not expect what you experienced before with your previous phone would happen on this phone. I don't know if one can use Greenify's aggressive doze function without rooting, but it definitely improved the battery drain overnight by a lot on my 7T Pro non-5G McLaren.

Terrible battery life with the OTA update

I have the stock 4.5.9 gingerbread update on my AT&T ATRIX. However I am observing a terrible battery life. There are too many solutions in the forum to follow. Can someone direct me to the appropriate one? I am rooted and unlocked. I used the unlocked 4.5.9 sbf for upgrading from from Froyo to gingerbread 2.3.4
Sent from my MB860 using XDA App
there;s a lot of solutions because poor battery life can be cause by many things, you have to find out what is draining your battery. try calibrating first let it drain until your phone turns off and then if you have cwm install then wipe batterystats and then a full uninterrupted charge
Try setting profiles in SetCPU and freezing apps with TitaniumBackup. Theres a topic for each of these two solutions.
battery stats 6h 3m 29s on battery (now left with 10% of battery)
Display 49%
Phone Idle 22%
Cell standby 6%
Android system 5%
Launcherpro 3%
xda 3%
Android OS 3%
this is just terrible .. i never had such battery life with Froyo. i dont understand what might be the problem. Meanwhile i will try to calibrate my battery.

Calibrate your battery.
Then freeze your bloat.
Problem solved.
dont forget you might also being playing with your phone a lot more trying to see all the new stuff in the update. Thus causing more battery drain.

There are some strange things happening with the battery. I let my battery discharge completely to the point where phone shuts down. Then I plugged in to charger, waited for 2-3 minutes so that I can start the phone. Started the phone and saw 50% battery. Don't know what's going on.
I was told by an admin from another site that most of the battery programs do not work with ova ginbread. You go to settings/about/status and observe the battery. I do no I was also getting flaky results with 2 of the battery programs.

That's a GB bug... there's a battery fix in the development section to flash which deals with the reboot battery jumping. (turn off phone at 50%, turn on phone and it says 70%)
I am having problems with my Atrix too. With my usage, I used to be able to get almost 3 days of battery life. Now it hardly lasts a day. I have checked pretty much all settings (sync, sleep) and all seems fine as far as I'm concerned. So I am having hard time trying to find what is causing this. The only suspect I have right now is wifi. I don't think wifi is sleeping even though I've selected "When screen turns off" in the sleep policy.

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 Asus ZenFone Max Pro M1's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

Can you Please share the usage Graph of your Device ?
Mine drains around 5-6% at night in standby! Its more than average considering the large 5000mah battery
Greenify / Freezing / disabling Google play services, or going nogapps improves battery life x10 times. In other cases, frustrate the app by denying it all permissions, so that it force closes every time it launches automatically (wakelock and drain prevented). Its an analogy to tying a runners shoelaces.....can't run, can't consume battery.
There are how many updates come till now for this phone? Please someone confirms it.
Draining issue is high.
Drained 29% last night..
Seems like software issue

That's true .my phone droped 20% charge last night.
It shows that the battery is consumed by android system is very high. I think it is a software issue

Use your phone till it becomes 0% and let it shut down Now press power button for 30 secs and make sure no battery is left to reboot the phone
Charge your phone till 100% with phone turned on/off (but don't use the phone while charging)
After 100% remove from charging and start normal usage till it becomes 0% again and now repeat same procedure 3-4times
Contact Asus CC they might provide better solution for your device after checking device details

Yeah, custom roms are highly optimized though it's unofficial right now I didn't think it would be this good. Well I'm on stock rom still and use greenify which does help a bit, the drain was 4% in 8 and a half hour.
the problem is on the apps that consumes power and data like facebook, instagram and some other similiar apps.
possible fix is disable them. and use fb instag by chrome. it makes the ram usage a bit less because the app wont use ram but "move" the ram usage to chrome.
ideal drain is more, after update and a bug also found Sim 1 hd capable.
I've noticed that my used ram is always above 2.0 gb. I wonder what's running in background consuming this much ram ?, this also might be the root cause of ideal drain I guess.

Battery Drain

Hi guys on standby time of 15 hours untouched my Mate 20 Pro is loosing 8% battery. Coming from my previous phone Pixel 2 XL which in the same time frame would loose 5% at most. Considering the Mate 20 Pro has a much bigger battery this equates to a higher battery drain as opposed to the Pixel 2 XL. How can I fix this drain and find the cause. The drain should be no greater than 5% in 15 hours of standby
Hi
battery life heavily depends on the applications installed and used. What I do in those cases is:
a) install a battery monitoring app (e.g. BBS )
b) once the offending package has been identified, it can be deactivated
c) in case its wakelocks you could also go and disable the offending ones
HTH, cheers,
Axel
I have the same issue; it seems my mate20pro is has the same baterry life as my s8plus. Huawei told me to fully charge and leave on airplane mode for 12 hours; it the charge looses more than 5% then its a fault.

In airplane mode enabled you won't lose more than 5% as nothing will work on the phone with no live connection

Mate 20 Pro Battery Draining Issue

Hi, I found out that my Mate 20 Pro batteey isn't as solid as advertised. The battery keep draining in standby mode. Yesterday, it dropped 9% in 8 hours of standby mode with WiFi on. However, the first few days the battery is very great but after 10 days of usage the battery performance dropped a lot ?. May I know is the AI allocation of power based on my usage pattern or the battery is faulty?
Looks like a rogue app...check the battery usage stats or install AccuBatttery to get full details.
Might have to restart in Safe mode to confirm it's an app.
Standby with Wi-Fi should be below 1%/hr unless some background activity goes nuts on you.
Try restarting the phone, i had the issue at some point, the switch from auto app management to manual, keeping just the apps i want. After the recent update(153) i switched back to auto. There is some issue with the app management, cause sometimes i lose just 1-2% of battery during the night, but sometimes 5-7%. Now i get an avarage of 36h+ of usage, and if not charging at 30-40% i could get more.
From brand new, my mate 20 pro drains about 12-13% if left overnight, also thought that was pretty bad

Xiaomi Mi note 10 lite battery drain Issue .

Hey I hope you guys are doing great !
Well i bought this phone like last month and the battery was working fine for the first few days but then its battery started decreasing faster than before while using the same apps as before. The most battery drains while its still in the idle conditions and overnight.
At first it would only loose like 1 or 2 percent over night but now it looses like 1 percent battery every hour it stays idle.
I have attached 2 screenshots below to show what I'm talking about . Both screenshots were taken 1 day apart and as you can see , sometimes the battery works fine but sometimes it drains a lot and its mostly when its idle. Kindly suggest me something if you got anything in mind that what might be the issue here.
Maybe the radio of your phone, that's what's draining mine fast.
And Facebook is a well known battery drainer
If you tap on the graph once, it allows you to find out the battery drain for specific time intervals and their length can be adjusted as well. Please do that and tell us which app or apps are draining the most battery during standby. Btw is your aod on? Aod prevents the device from sleeping properly so the battery drain can rise up to 2% per hour if its on. If that is not the case as well, try turning off location and nfc if they are not being used, and turn off wifi and cellular before going to sleep and then check the drain. Also try disabling google play protect from play store, and check out the link below which improved battery life for many people including myself:
