battery bug - OnePlus 8 Questions & Answers

Just realised why my battery screen looked so weird. It's outside the grid!
Is there an easy fix?

Given that the OP8 hasn't been out for 44 days and my battery usage is in portrait mode only, what device was this?

[Q] New Battery Calibration

I bought a new battery for my oneplus one from vifocal.com and I think its original battery. The battery seems to be very poor. I use my phone for 1,5 hours from which the screen is on for about 1 hour and the battery has drained down to 50%. Yesterday as my phone went to zero I turned it on in recovery mode to keep the screen on as long as possible to really kill the battery and the screen stayed on for at least 2 hours. How is that possible if the battery indicator shows already 0%. Anyways I believe the battery drops down to 0% even really there is a lot of juice in the battery. Is there anyway to calibrate the battery so it would show the correct percentage and is there anyway to tell how big is the battery really? whether I got a fake one or not. thanks

I've had an opposite issue few times - phone was shutting down while it was show that it still had battery (20% was the worst case). I fixed it by discrharging fully, then letting the phone charge all trough the night. this was the recommendation that I found on OPO forums from someone from their team.

Battery suddenly only lasting 12 hours

Hope you wise folk can help.
Around last week my phone's battery struggles to last 12 hours on a single charge, up until that point it would happily do 24hrs +
Not downloaded anything new, and not using it any more than before.
I'm baffled.
It's running stock on the ee network.
Any advice would be great.
Currently got Gsam monitoring my battery to see if that sheds any light
What does the battery usage say?
Hello, look for any Apps that was updatet in this timeline.
I think it´s possible that one or more of these will drain the Battery, because they will influence they Deepsleep of the Phone.
Nice Greets from Germany
Well things have taken a turn for the worse.
Battery on 70,% at 11pm turned on airplane mode.
By 06:30 it had dropped to 30%
All battery info shows it was in airplane mode, so how did it eat 50% of the battery?
PS how do you post thumbnails/ pics?

Strange standby battery draining

So as you can see in the top of the screen shot my htc u11 went from 80% to 67% in 8 hours even though it was on standby with Wi-Fi turned off and on airplane mode and with also powersaving mode and hibernation manager.. I mean like what the hell.. Someonen tell me how this is possible. This is rhe worst standby i ever had on any phone

Please post battery usage details while in aereo mode to see who is responsible of this battery drain.

That's not battery usage...I know you're a newbie here, but you should know the basic battery information comes from phone settings.
Have u updated to 1.27? It fixes the standby drain. Used to have 60-70% drain overnight to 30+%

If you really want to determine which app drains your battery, a full charge is recommended.
Otherwise use Gsam and use adb to enable advanced mode, add a rule for "since now".

Wow 30% overnight? That doesn't sound right either...I probably lose 0.5%/hour on 1.13...my phone doesn't go into airplane mode over night either, I just turn off WiFi anr 4g...
Adi - given your countless threads of issues you've had so far, why haven't you returned the phone or gone to a help centre or something...it seems you have one problem after another...
I meant 30% of total stanby drain. Not 30% loss

If you're really serious about putting an HTC phone aside and bot touching it for several hours you should use the extreme power saving mode. It will still alert for calls. I come back after 12 hours to just a few percentage less.
That's why I sold my HTC U11, lost 5% an hour on cell standby, very poor battery life on this phone, the dongle stopped working and cracked the curved edge glass. Good camera though, and Iike HTC Sense. Bought a Moto Z Play, amazing battery life, easily 2 day battery life, has a headphone jack and a great Amoled display. Love this phone and nearly stock android.

severe battery drain again pixel xl

I came here because I have a severe battery drain issue. Sometimes I can fix the issue by rebooting the phone and then not using it. This issue has been coming and going I think since android 10 but it may have occurred in android 9. I had this issue a few months ago and the issue stopped on its own. To workaround the issue I was rebooting the phone when I noticed the severe drain and then tried to avoid using the phone.
For example I charged my phone (pixel 1 XL) before I went to sleep. I charged it to about 85% at 11pm. I took it off charge and went to sleep. At 530am I woke and checked the phone to check the time. The battery was at 15% and in power saver mode.. Usually I get 1 day usage (6am to 6pm, with streaming music to my headphones at the gym and messaging throughout the day) and get home with 65% battery. This issue has come back again now that I am traveling abroad.
I reset the phone to factory yesterday and only installed webex teams and whatsapp. The issue persisted yesterday. At lunch, we spent around half an hour eating and the phone was screen off and on the table and the phone dropped from 65% to 55%. I decided to remove webex teams and reboot the phone. The battery remained at 53% for approx 2 hours. I thought eurika, webex teams is the culprit. But unfortunately last night the same battery drain issue occurred and I had to charge the phone again at 5am.
I dont know that the issue is occurring until it is occurring.
The battery usage shows no usage by apps during this issue, and same when I show all device usage - for example I'll have say webex teams using 1% and screen using 1% but the device has dropped 60% of battery and there is no indication of where.
I dont mind to install a custom rom but I have not done any custom installs on this phone at all at this point.
Also I never used NFC until a few months ago for the banking app which I used to have. I just realised NFC was on yesterday and I've just switched it off. I just wont know if this helps until later today when the battery is dropping quickly. Although it just dropped 2% while typing this so I dont think it has helped. I just turned on data saver and battery saver and will see.
I am at a bit of a loss - has anyone else had this problem and found the culprit or a fix?
Update - battery saver and data saver does not stop the battery drain. 2% drop in 20 minutes with phone on the desk with screen off.
I decided to give up, re-install webex teams and go for breakfast; while leaving nfc off, battery saver on and data saver on. At breakfast, the battery did not drop at all. Uptime is 9 hours 50 minutes (cant remember if I rebooted before breakfast) So almost 10 hours later and I have been using the phone over wifi on occasions and a few phone calls and whatsapp. The battery level is now 55% so it appears that the issue has gone away at the moment.
It's driving me nuts as I cannot work out a trigger. It almost seems like something within the android system is doing something and it's being hidden from the systems battery usage calculation. 3rd party apps also do not show any battery drain but the battery drains. If the battery was faulty then I would expect this issue to not get fixed after reboot (or even by itself). I have reset the phone 2 or 3 times now and the issue is still present afterwards.
Tried to google for answers and didnt really find anything apart from one guy saying his phone was draining and getting hot at the same time. Mine does not get hot.
I suspected malware or something like that but I dont see how it can be possible that malware is there after factory reset.
OK I think I have made some progress - although can't be sure because this issue does go away and then comes back! However, this time I am refusing to reboot my phone so I can work on it. I am flying back tomorrow at 4am and so I need battery to last as long as possible. I have installed all of my important apps that I need to use. Given the issue is there when I have only 2 apps, the issue cannot be related to the apps I removed so I installed all of the important ones.
What I have done now:
1. turned off dark mode
2. opened the app permissions for the "google" app and changed the location permission from "always" to "only while using the app".
GPS Location is always off unless I am using google maps anyway but it did not stop battery drain previously!
As soon as I changed the permission app for point 2 above, the severe battery drain stopped. Take a look at the screenshot. You can see the severe drain on the left of the graph. Then the very severe drain was when I Was actively using the phone during the issue. Then I charged the phone. Then I changed the permission and you can see the graph have a flat horizontal line which is showing next to zero battery drain! I do not have battery saver or data saver turned on anymore. And I have been using the phone a fair amount.
Touch wood and fingers crossed. May be this will also stop google from emailing me every month with a google map breadcrumb trail of where I have been going.
EDIT - uptime of the phone is 28 hours and counting. Although you can see the charging points in the screenshot.
I have the same issue. My battery was just recently replaced too. I'm going to try the suggestions in your latter posts and see if anything improves.

Question Xperia 5 III Standby battery drain

Hi, I'm experiencing a standby battery drain on my Xperia 5 III. I've just bought it, it's updated to A12, did a hard reset and software repair with Xperia companion. I lose around 1.5% per hour, around 12% per 8hours of sleep. Whether I have SIM popped in or not, GSam reports Mobile radio constantly working and it stops only if I turn airplane mode on.
I have Stamina mode on, 60Hz only, turned off mobile data always on in developer settings (although it shouldn't matter when SIM is out), smart connectivity is off, everything else I found that could be battery consuming I turned off.
Is there anything else I can do, besides flashing it again with Xperia companion? Or is this normal for this phone?
I suspect you're going to struggle to get a reply from someone that's performed this same test. My phone was charged to 90% 4.5h ago. I've used it for web browsing for about an hour since it was removed from the charger. I've never used Stamina mode. I have 120Hz display on. I use the Always On display with the clock and a graphic. Screen brightness is at 50%.
Battery is at 74%. I have done zero investigating about what has been draining the battery, as it strikes me as normal usage based on my experience with Xperia and Huawei phones.
I think you are right, the user base seems to be much smaller than I thought.
Luckily, my battery drain has improved, last night it drained only 0.90% per 7h of sleep, putting a SIM card in and turning Stamina off helped, it makes no sense but it fixed it. If I'm not wrong, as per GSam, my phone also went only into a deep sleep and never into light sleep, now it enters both.
I find that after a reset or an OS version update, the Xperia phones take a week or so to sort themselves out. I don't know if it's optimizing in the background or what. I have noticed this since my Z5, which I bought 5 years ago.
t an update today on my 5 III and after updating I have significantly better battery life and lower overall temps.

ive been using my xperia without a sim and the battery life is also terrible. i havent switched from my old phone yet.
is the battery life better on the android 12 update?
I can't comment on 11 vs 12 usages as I didn't use my phone on 11,only 12, but others already reported improved battery life on 12.
My battery life significantly improved after 2 weeks. I did recalibrate my battery, two times drained it to 0% and charged until 100%. I did apply all the battery-saving tips and tricks available and suspended whatever system apps I could. Depending on the usage, I could reach 7-9h hours SOT easily, probably even 10 with stamina turned on. Updates really helped this phone in every possible way. IDLE battery drain was the worse thing with it and now it varies from 0.20 to 0.70% per hour. Remember to close all the apps when you don't need them,.
In the developer options you can restrict the background processes. Had 4, now 3 selected.
My apps notify me reliably, I do not notice any difference, but the consumption in standby is only a third as high.
Everything else did not work for me.

Important, you have to set this Option after every reboot.
