QUOTE(SwarmTroll @ Apr 12 2021, 09:41 AM) I also wanna see if the others here are the same as well in terms of overnight/idle battery drains. This is actually worse than my F1 lol In my case the highest battery usage was "Others", and no further info was shown.

QUOTE(Rudd @ Apr 12 2021, 11:36 AM) Around 20%. I think for mine culprit is AOD notification animation/screen light up. Will try disable the notification alert tonight and see tomorrow. My AOD was scheduled to off during 11pm-7am but still drains 20% overnight. Just FYI. This post has been edited by poweredbydiscuz: Apr 12 2021, 11:44 AM

QUOTE(layzieboy @ Apr 12 2021, 04:14 PM) to those that received theirs, does your unit suffer from uneven display colour like this guy? https://c.po.co/global/circle/circledetail/11369QUOTE(KopiChia @ Apr 12 2021, 04:24 PM) Anyone have some difficulties with full gestures? I feel some swipes that I am use to don't seem to work at some menus etc. Heck I can't swipe go back out of settings or minimize. I am going back to dock navigation. Also for some reason full gestures are not saved next reboot it's back to old school navigation. Mine don't have these issues. But the battery drain... already down to 50% with just 2.5h SOT, due to unknown power consumption by "Other" apps.

To those without battery drain issue, mind to share what's your percentage of "Other" under battery usage?

QUOTE(berrycoo~ @ Apr 13 2021, 12:08 PM) Wow not bad mine still same 7-8% overnight. Are you on 120hz? Feels to me the screen is not as power efficient as Samsung flagship phones (probably due to no VRR?) You can definitely drain this phone in 1day of usage Yes 120hz. The screen and the speed are what I like the most about this phone. It's weird that last night 6 hours idling only dropped 1%, but now it steadily drops ~3% per hour even though I barely used it. Let me change to 60hz and see if it helps.

I noticed something weird about the battery stats. When my phone left 10% battery, it shows that 37% of power consumption is from screen, which is 778mah. Doing simple math, 100% power consumption is around 2103mah. I have used 2103mah and left with 10% charge, which mean 100% charge is only 2337mah. It's far off from the advertised 4520mah. Am I misinterpreting the data? Or the displayed battery percentage is inaccurate? Maybe need a calibration? It can't be the battery itself cause it's new right.

QUOTE(tshin810 @ Apr 14 2021, 09:32 AM) charge to 100% is not accurate. try below 100% and check the result. But poco says fully charge then check.  QUOTE(lazyman@home @ Apr 14 2021, 10:19 AM) And the app does not show what is the charging voltage too.. So still don't know what is the charging power It's written there 4.326V

QUOTE(Jue @ Apr 14 2021, 01:44 PM) Hello guys may I know how are your batteries holding up? I'm using the 8/256g model and I'm losing 1-2% averagely every 10-15 minutes with 5G off and screen 60Hz yesterday. Today seems better. Charged to 100% at 10am and currently sits at 92% @ 1.44pm. Read through few pages back and you'll know it's a common case.

QUOTE(AzureYuki @ Apr 16 2021, 09:05 AM) Hey everyone, I just got my F3 a few days ago and I noticed that the standby battery life was mediocre. 20% overnight on first charge, 9% the next 2 nights on second and third charge respectively. Then there would be some weird drain on my fourth charge (5% in 30 mins idle!). After trying some things, I got my battery standby to drain just 2% over 9 hours (Wifi on, no AOD). Here's what I did: » Click to show Spoiler - click again to hide... « 1) Disable MSA (Settings > Password & Security > Authorization & Revocation) and any ads in the relevant app. 2) Disable Digital Wellbeing (Settings > Digital Wellbeing & Parental Controls > Upper right 3 dots > Manage your data > Uncheck Daily Device Usage). This one seems to affect battery the most from my testing. Maybe someone else can test it and report some results below. 3) Optimize any apps you can (Settings > Privacy protection > Special Permissions > Battery Optimization). For this step, I'd actually avoid optimizing apps where you rely on notifications such as Whatsapp or any kind of messaging app. I find that Xiaomi's app killing can be too aggressive which may result in delayed notifications on Whatsapp like what my F3 had right out of the box. 4) Manually adjust battery saver behavior for certain apps (Settings > Battery & Performance > Tap upper right gear icon > App battery saver). For all apps by default it's set to "Battery Saver (Recommended)" I believe. I suggest putting more important apps like any messaging/communication app to "No restrictions" while lesser important apps that don't need the background privilege like MySejahtera can be put to "Restrict Background Apps". If you're unsure, just leave it on Battery Saver.  Hopefully this helped. I'll report back in a day or two after more observation on the battery. I've done everything above since day 2. When the battery is 100% or 99% full, it's standby battery is great (1-2% over 8 hours). But once it's start dropping to 95% and below, it will steadily drop 2-3% per hour at standby. At least that's my case.

Suddenly can't access some banking apps and said my device is rooted.
After restart the phone can access most of them already except 2 banks. Any advice? I did not root my phone.
Edit: after another restart can access all now. Still don't know what's the cause though.

QUOTE(KopiChia @ Apr 20 2021, 12:22 PM) Not sure if it's available yet. I just saw this in reddit.  Good to know that xiaomi acknowledge the battery drain problem and giving solution rather than calling people overreacting and ask us to optimize our phone ourselves.
