Suddenly very bad standby drain just 3 days ago? - Xiaomi Mi 8 Questions & Answers

I've had my Mi8 for about 2 months now, and I am on MIUI global 10.2 Stable (10.2.2.0).
3 days ago, standby battery drain went up a lot. I went from 6-8 hours SOT to now 2-3 hours SOT, the phone is draining 5% standby per hour, I can barely get through a day without charging anymore. Any reasons why?
EDIT: Nothing has changed in my usage between 3 days ago and now, my apps are exactly the same, battery settings exact same, even the places I go are the exact same, why suddenly such bad standby drain?

Very less battery drain, what did I do to make this change?

Last 3 weeks or so I have been optimizing to save battery power, read most of the thread but the best I could get was 12-16 hrs, surprisingly today last 12 hrs since I charged it fully, it has ONLY consumed 27% till now, daily usage include checking mails & making calls & xda forum browsing mostly.
I am concerned as to what made my battery so good suddenly as I want to follow the same foot steps, only thing i did differently is that I completely switched off phone (1st time ever while charging) for 2 hrs when the phone was charging.................could that be the reason for so good battery life?
After 24 hrs it shows 38% left (2hrs of extensive use in the morning with music in background), that is unbelievable to me, can someone help as to suddenly what is making this battery life so long?

I barely get through the day.
My usage is when my screen is on refresh all my mails. thats is
My internet use is hardly 1 hr and no music/game for the fear of my battery.
Today in 4 hrs i've lost out 15% battery.
What can i do here..please suggest.

Battery Life, an interesting observation

Hi devs, as I know there are many people complaining about battery life, I wanted to share an observation and also ask for an explanation behind it... My Note used to last around 2 days when I got it but after updating to JPLA1, it started to die on me in less than 24 hours.
I didn't want to factory reset. One day the battery died on me completely and phone turned off. After recharging, I'm getting about 1% battery drain per hour on standby... if I chargr the phone before it shuts off due to an empty battery, I'm back to 4-8% battery drain per hour on standby (all other settings the same)... I have been able to reproduce this effect many times... Is this a kernel issue or do I need a new battery?

[Q] Strange battery issue - SGSA

I bought SGSA 2 months before and updated it to JB with Kies (Unrooted). I had around 30-40 apps installed along with 2x battery saver. The battery used to remain for 2 days on phone calls, texts, minimal wifi and games usage. When I fully charge my phone at night , lock it and wake up in the morning, it would have dropped to 99% or 98% I was quite happy with the performance.
But over a period of time, it started lagging a lot and touch became unresponsive. So I factory reset my phone 2 days back. and installed 25 apps again. But now the battery drains like dam. I charge my smartphone to 100% at around 11 pm and when I wake up around 6 am. The battery percent would be about 54%-52%. I dunno what to do ? Even tried the same 2x battery saver but it didn't work.. Please help !!

Depends what apps you instaled. If you have good amount of ones that use autosync, it can cause battery drain. Also turn off internet overnight.

Battery Issues

Hi All
I bought Nokia 7 Plus yesterday and set it up, but the battery drain so fast. I left my phone to sleep with wifi on throughout my sleep it drains 10% with just pushing notifications from FB, like everytime I will get FB Notifications and not open it it will drain 1% of the battery.
Remove fb and see magic
U just answered to your question. It's not the phone, it's just crappy facebook app.
Facebook Lite is the way to go if you need FB, I think - normal version eats battery a lot, and I'm not sure if that will be fixed at all - seems like they don't care.
If you have to use Facebook, use Facebook lite or alternative apps like Friendly.
Hi, I got Nokia 7 Plus yesterday and started using it today. Initially with the battery percentage came with package, battery draining was slow. After doing first charging from 21% to 100%, battery is draining too fast. It is common for some batteries and takes some charging cycles to get battery optimized. If battery draining is happening too fast even after 3 to 5 charging cycles then there would be some fault with battery.

I got my phone day before yesterday & its now running Android 8.1 with the May security patch. Since the time of use, I've charged my phone only twice & both times charged it up to 100%. I feel the batter is draining. Please have a look at the screenshots and let me know if the battery consumption is fine or its draining fast. The battery dropped by 1% in 4 mins of the phone being idle with the display closed. Also the stock camera app is consuming a lot of battery.
I can confirm a very hard drain, too. No way to reach 7-10 hours of usage.
i'm getting about 5-5.5 hours of sot with moderate usage... Checked the app usage..where it shows PUBG used 12% battery in 38 min, 45 min of youtube drain 8% 26min Instagram drain 5%...I don't use fb much on phone when needed i mainly use fb lite... .i don't use auto brightness. so my brightness level is always 45%.. in overnight( well it's like 5-6 hours) battery percentage dropped 4%.. Wifi is always on and GPS is always on high accuracy.. in power saver 19 apps are allowed for background activity...
Battery drain
I just purchased my phone yesterday and used it for some time. I put it on charging at around 20% and didn't use it until full charge. After it got completely charged and then I just used it for few mins it went down 100% to 95% very fast; later after few mins I started suffering net and did misc stuff for about an hour it went down to 85%. Next morning I saw the battery % was 81%. Is this normal? I mean how can it last for 2 day as the company claimed. Aslo I am android 8.1.0

This has been a comman issue with Nokia 7 plus, including me. My battery had high discharge rates in both Oreo and Pie. However, post March security update, I am seeing some good battery life. I would also suggest to update to Pie and update Device Health from Play Store. Hope it works out for you.
try letting the battery drain to 0% then charging it to 100
TA1062 with build 00WW_3_51F here.
Before the march update, the phone could last for almost 2 days with moderate usage.
After the march update, I barely have 5 hours of standby time, and like 2 hour of usage time. This is crazy ! Not heating, but also randomly shuts down while it says like 65% remaining battery. I haven't changed anything else !!!
Does anyone have any idea how to improve this ?

Do a factory reset

Battery friendly ROM

I'm using xiaomi.eu 12.0.5 QFACXNM and the battery drain is brutal: 11% battery drain at night in 9 hours without touching the phone. No airplane mode, but wifi and data off.
I restricted almost all apps at background and problem is not solved. I'm doing 3h SOT or even less at day.
So... what's the rom with the BEST battery and the best SOT? I don't mind the other features, if it's AOSP I appreciate if I can install ANX camera and GCAM (both).
Thanks.

I had very good battery results with PixelExperience - around total 40h with 3h screen on time (yeah not heavy usage). Right now I'm trying PA Q5

3h SOT is not a good result, don't you think? I was expecting something like 5h or 6h of SOT with a normal use... I know with 3300mah battery it's complicated but I don't use my phone with heavy apps, I don't play, only use instagram, photos, twitter, whatsapp/telegram and stuff like that...
I recommend PA.

for a 40h+ total with bluetooth location and wifi always on I'd say it's a very good result
I'll check both. I fully charged my phone this morning. 7 hours later, without any use (check my instagram and twitter couple of times and responding some whatsapps), it dropped 10% (to 90%).. At least six and a half hours were in deep sleep.
I think this isn't normal.
That also can be a signal for a dying battery as well. Approx. 1 % per hour in combined usage is a good average for AOSP ROMs. At moderate use, similar to your profile, the battery here last for four days with 4 h SoT. 8 h SoT over two days is possible but not what I reach often. Mi9 is running PAQ5.

I was thinking the same. At this hour, less than 12h after the last full charge, and with no use at all cause I'm currently working at home, so I use computer (like I said, watch a couple of times instagram, reply to a few whatsapps and check twitter a little) battery is at 80%, with 30 minutes of SOT. Something is wrong, and maybe you're right about battery.
I'll try PAQ5 and crdroid with quantic kernel... despite I like MIUI, but xiaomi.eu is an extreme battery-draining rom...
My Mi 9 is running several AOSP ROMs since more than one year. Since then I've simply no idea about Miui and its battery consumption. Tbh I'm not too much interested in battery life at all. I'm not an outdoor guy having access to a power plug only once in a while. I'm living in an area where power plugs are widely available. So running out of power is not a major threat to me.

I usually have a charger near, but it happened to me that, in a long session of photos, or in a heavy use outside my home or my work, battery dies more sooner than later... and that sucks.
For example, watching forums or instagram, it consume 1% each 5-7 min, and more of that, instagram and web loading are not so fluent as it should be, so... I'm gonna try aosp for a while.
Crdroid, Paranoid and Iodé OS seem the best choices, I'll give a try to the best battery-saver rom...
Changing ROM only might not solve your battery problem, if the problem lies elsewhere. I use the same ROM and I could get 4-6 hours SoT per charge, over a day of use or so. This is a 1 year old device so battery is no longer 100%. If yours is newer but you get worse result than mine, then it's something in your configuration, not the ROM.
Sure, in these cases I usually carry a power bank with me. Actually I can't recall when last time my phone totally went off power.
For the AOSP ROMs I can't tell about battery behaviour. Things like SafetyNet, banking app and G-Pay are so much more important to me that I never considered changing the ROM since PAQ5 does simply everything I need.

this phone has some hardware issue with the battery, some chip is not properly registering/measuring. You have to "reset".
I have more than 8h screen on time 0~100, and I have the phone 15 months.

I got same problems with you and in my case. I found out that my mobile signal was not stable, then phone auto switch network try to find 4g -3g -2g and it happened couple of times. When I' back to my hometown, battery is only down 2%.

I was thinking the same, battery duration is ridiculous. Last night, 1% battery per- 5-6-7 mins using kiwi browser/instagram. And 10% battery out last night with wifi and data deactivated. Now I have 56% battery with very few use of the phone. Charged it 24h ago.

I don't have a powerbank, I think I should buy one... Like I said, I still have problems with Internet, instagram stories and some webpages load slowly even with WIFI, so maybe it's a ROM problem...

I live in a great city and and I haven't gotten out of it since the pandemic started, so I don't think that's the problem...
I have miui 11 .eu rom, I have a post explaining how to get 8:30h sot
Your problem is xiaomi crap that are draining your battery and making the phone not measure it correctly.
Xiaomi programmed obsolescence on battery
H, since I updated from miui 10 to miui 11 and even now that I have miui 12 I have noticed that the battery doesn't last as long as before. I state that since I purchased the phone (July 2019) I have always charged the battery in the best way...

Hello im using miui 11.0.6 with a new battery and i get 4:14 on SoT, what version of miui do you use?
I on my xiaomi mi9 I installed the battery increased by 4000mha, I changed the kernel values with a file manager by making the phone read the same battery capacity and I do six hours of display on! To do this you must have root permissions and buy 4000mha battery ...
the path to take with franco kernel manager is:
/sys/class/power_supply/bms/charge_full"
/sys/class/power_supply/battery/charge_ful
Through a file manager, that is the path to follow to edit the file
