The bug in WiFi has been fixed in the new firmware, maybe this will increase the battery consumption!

Well, "fixed" isn't really true for some users that are facing the wlan bug.
The phone still disconnect from WiFi router every couple of minutes.
The change is that it RECONNECTS now few seconds later.
But I'm sure it is still not really battery friendly at all...

Xiaomi Eu 11.0.9.0 last roms , best battery life ever

(HELP) Very Poor battery Standby Time on Redmi Note 3 Kenzo....

Hi there. I've Redmi Note 3 Kenzo for a month now. I've problem with my phone battery backup. It have very poor standby time. Even when I'm not using my phone it continuously looses 2/3 percent of battery per hour i.e around 40-50 % in a day . I usually turn off data, wifi , GPS etc after using even though its the same. I tried MIUI 8 Global as well as Chinese (Both stable and Beta version), even downgraded to MIUI 7 on various version, used eu.xiaomi ROM, MultiROM etc but still there is same problem. In some custom ROMS like CM 13 and RR Remix there is a bit improvement in standby time but not as it must be in 4100 mah battery. As I like using MIUI than custom ROM so my problem is still there. I am tired of flashing various ROM every now and than. Does anyone facing same problem. Can anyone help me and suggest some ways of solving this problem. Any help will be highly appreciated. Hope someone will Help. Please................

+1,
i am too tired of flashing this and that ROM,but battery is too horrible for me ,mostly with miui ,I get only 5-6 h sots with miui,
however my experience with nougat cm is quiet satisfactory ,it gives at least a reasonable sot,if u find something pleaaase pm me too.
It's most likely an app that is causing this. Are you able to see if the phone is going into deep sleep?

I tried Wake Lock Detector but couldn't find any app causing the problem. I even tried Greenify and Amplify app but no improvement. It seems its Problem In MIUI Rom cause using custom ROM i get a bit improvement in standby battery life. Any suggestion can you give like Which version of MIUI Rom is better for battery life.
Is there anyone who can help? Please.....
I'm currently on xiaomi.eu rom 6.11.3 (since it is the only one that allows for use of custom kernels with goodix at this time) and I get what I feel is good battery life. You could try this ROM if you have an unlocked bootloader.

Thanks for your reply. But i already tried that Rom. And yes i have officially unlocked bootloader. I usually get satisfactory SOT but my only problem is standby time. Battery is decreasing constantly even without using my phone. Currently using RR Remix Rom and getting a bit satisfactory result but i really like MIUI so I'm looking for a fix. Thanks again.

Use stock kernel with nitrogen os and use radon with exodus

Decreased battery performance

Hii.. I've just got my new redmi note 4 (SD) 4 GB ram variant 10 days ago. And after getting my device I updated it to official MIUI stable nougat update. Battery life was just great but just after a week I'm experiencing strange battery drain. My battery drops by 3-6 % whenever I check my phone after a whole night. Even when I just check my phone after regular interval my battery drops by 3-4%. Please help me as nobody will ever want their brand new device to behave like this... :crying::crying:

Battery drain and firmware relation?

Hi there!
I love fresh stuff so updates of ROM, kernel and firmware are must have for me. For the better and for the worse. It happened for the worse. I've been waiting a year for stable pie roms to appear that have zero screen wake delay and Syberia was the only room with EAS support. I thought why not. So flashed Syberia Latest in may of 2019 and latest stable, global firmware from xiaomifirmwareupdater. I was very satisfied with Syberia's experience and even more it's kernel performance that I didn't have to flash a custom kernel. I've been using the rom till yesterday for about 3 months and always flashed newer updates of Syberia and opengapps pico. My mido device started to drain battery much faster. Even that much that for example when I wake up at 6:30 am and arrive at work for 8:00 10-20% battery juice is already drained even though all I did was read comics in a simple reader. Tried to solve the issue but after all my mido device is 3 years old. got the conclusion that my battery sadly went broke. Still it was extremely annoying for me that I can't read comics for more than 7 hours during my shift (I'm a seasonal pool warden so I do nothing from 8:00 to 20:00) because my phone's battery dies no matter how I try no to let it. I've had enough so I changed rom and even firmware. Flashed latest China stable firmware which arrived in july and latest Pixel Experience. See wonder now my battery drains way slower and the phone shows me that it can run for 1 day and a bit more from 100% to 0%. I'm so happy and relieved that there isn't anything wrong with my battery.
I want to find out what caused the extreme drain. I really do. Could you guys please help me find the cause? Was it the previous firmware? Syberia updates? The stock kernel? The opengapps packages?
I have a few clues but I hope there are others with more knowledge on battery factors. Thanks a lot in advance.
Maybe kernel and apps usage. You should check the in battery statistics it may mobile network standby.

I used better battery stats all the time and it showed nothing unusual. Not on Syberia, not on PE. Furthermore I used Migrate app so I have every single app on PE that I had on Syberia with exact same settings. Perhaps the high battery drain was caused by one of Syberia's system app? If yes shouldn't I've been able to see it in BBS? If it was caused by an user installed app shouldn't the problem migrate to PE as well with the apps? I still think firmware caused the battery drain but I can't belive something certainly based on my gut.

Perhaps yes. Perhaps no. I use BBS all the time and it never showed me unusual activity on Syberia. Furthermore I used migrate app so I have every single app on PE that I used on Syberia with the exact same settings but there is no bettery drain present. If user installed apps were the cause of battery drain shouldn't the drain migrated with them as well?
I still think it could have been a firmware issue.

Did you ever try to use a bugreport + Battery Historian (Google's own tool) to check what is using your battery? I put together a small article about it on Telegra.ph the other day. Which MIUI ROM's firmware are you using actually at the moment? Some ppl. says that in less LTE covered areas the firmware derived from global stable ROM V9.6.3.0 does a really good job. Did you try to up- or downgrade the firmware? Did you ever try to disable LTE and use 2G/3G preferred or 2G/3G auto mode?

No. I never hear about those tools. All I saw over the web was better battery stats and it was widely recommended. So I used that. I was using 2019/05/16 china firmware while the battery drain was noticeable. Now I'm on 2019/07/19 china firmware and the battery drain is gone. I dunno. Since I didn't find anything about cellular network signals causing the battery drain I didn't experiment with it at all. It's constantly turned on. Like for a year now. I'll try 9.6.3.0 stable firmware and report back how battery drain is.

I would never use the chinese firmwares on a global phone, especially when your are not in China.. I had issues in the past with some chinese firmware versions but never had any with the global ones (here in Hungary we use different carrier technologies than companies in PRC and as far as I know global is optimised differently for a different market, not for China).

I see. Good to know. I've been using chinese firmware for a good while now without issues. But I flashed the adviced 9.6.3.0 global stable now. I'll take your advice and stay away from China firmware. It'd only make sense.

Horrible battery life

Hey, I have a redmi note 4 snapdragon version and I have flashed aosp extended rom and franco kernel in it, but I am getting a very poor battery life, hardly 1 hour screen on time and the phone shuts off by the time battery gets to 30 to 20%. My phone is rooted too and i am not using any kind of battery saver app.
:crying:
I think this is an hardware issue but, I am no expert so please help me on this and let me know what should i do. Thank you.

The problem started probably when i rooted my phone on stock rom(miui 10), the very next day i cleaned every thing (including my firmware accidentally) to flash custom rom, then after flashing i found out that none of the hardware components are working and i posted a thread about it and as per the answers i flashed a latest chinese firmware for redmi note 4.And it worked except i started noticing an awfully bad battery backup(hadn't noticed before as all this happened in just 2 days. (as a matter of fact the battery went down 5% as i wrote this, oh 6 now!)

Cleaning everything, as you stated, including the whole firmware,
You answered your whole thread yourself, just flash stock frimware, then flash AEX like flashing any normal ROM.
I have the same problem, the battery die after 1h screen, when the battery Is on 20% the device shutdown,help me pls, i have rr with franco kernel.
hi OP. base on what you are describing, it looks like your battery is dying... nothing to do with the OS. be careful 'cause chinese batterys (like 70%) turn out to be real sh*t (on my own experiance). consider to replace battery from a confiable retailer or change device.

Question What do you think about MIUI 13 battery life?

Just upgraded to newest MIUI 13. I factory reset my device for the new OS update. I'm in doubt if battery is better or worse.
What is your experience?
Mine is 30% better
I have not noticed any difference after upgrading to MIUI 13, it seems to be the same.
Everything is better on miui 13 except dark mode for individual apps (not working). You?

Haven't really seen any big battery improvements, except that it's true, it lasts a LITTLE bit longer.
I'm using a mi 11 ultra and since i updated it to MIUI 13 battery life went from average to terrible. I now barely reach 5h of SOT... I reset the phone and tried many things but nothing worked. I wish I had stayed under MIUI 12.5

I'm sure by flashing the MIUI 12.5 rom that you can find on xiaomi's website or with xiaomi.eu ROMs, you should be able to rehave that battery life. But, you should also install betterbatterystats, to see which process use that much battery. 5h of SOT is pretty low.
I don't want to go to through the hassle of downgrading.. I shouldn't have to do that to have the battery life i used to have... Xiaomi doesn't know how to handle updates properly. Thank you though
I found ultra battery saver mode to be very bad. It used to have 350 hours and now it's 55 hours. Rest all seems to be okay.

From the first few days of testing, I'd say it's worse, and quite noticeable. I get around 4 SoT, usually it was around 5-6 with 90hz... I did a fresh install on a factory reseted phone Tho it might be the fact that neither the miui backup nor Google backup saved any of my settings, so might be few weeks till I get my phone into it's operating window...
But then again, phone seems a lot faster to me, and cold as ice.
When will MIUI 13 come for Xiaomi 11 Lite NE 5G? Any Idea?
I got OTA notif ten days ago (but I don't want to update,)
You can find another thread and posts (search, read thread titles for 5g ne) where other users already received and updated
After all, if you don't receive in your country (who knows Xiaomi policies about updating), you can find the MIUI 13 firmware on Xiaomi Firmware Updater site, and by googling instructions how to install manually

No, I just did a classic OTA update.
At 80% (I usually don't go more than that on a regular day), I got a battery estimation around 20 hours.
most of the time, SOT 4 hours, facebook, whatsapp, messenger, twitter
