Need emui 4. - Mate 8 General

Hi guys, upgraded mate 8 to nougat but buttery drain is huge. Downgraded back to what turned out to be emui 4.1 and it's the same thing. Battery drain is still quite huge.
does anyone have a copy or link to L29C636B320 or the last emui 4 Asian spec that works?

how about trying to determine what the actual cause for the battery drain is before flashing around like a crazy person?

i have to agree..don't rollback untill you investigate. i am on latest mate 8 firmware and have no battery issue.
about 2 days of battery with 4g mobile data enabled.

In a way you probably have a point but I'm simply following instincts here. I do believe it's the firmware itself but not sure how.
Ive rebranded to c636 emui 4.1 and it's a little better but still draining. To put that in perspective, I'm losing 18% per night with phone turned off. This never ever happened with emui 4. Infact on emui 4 with heavy usage i.e phone calls, music player on, Bluetooth on and a good 2-3 hours of gaming, internet browser and msging, I was still getting 2 days usage before getting to 20% battery. I had Kernal auditor but no other app to adjust battery performance.
Might sound silly but what's the best way to determine whats causing drain? I don't have any tools apart from SRK tool and Huawei extractor.

by "phone turned off" u mean u completely switched off the phone? as in power / shutdown? or just airplane mode?
if its the former, this points towards the battery itself, not the software. how old is your phone?

If you loose 18% with the phone switched off....well i think your battery is dying.

I've been thinking about that but I'm still not convinced. I might take the phone back to original c185 spec and see what happens.
Besides, last night it was fully charged at 100%, just plugged in the charger and it's showing 78%.

Battery drains very quickly

Hi all
I noticed that the battery runs out quickly.
It holds only 12 hours in normal use.
While I was at 48 hours with my Huawei mate 8
Is there a solution to this problem?
I have attached the phone version if it can help.
Wait bro, your firmware version is outdated, latest Lollipop firmware is 2.20.40.184, but yours is still running 2.20.40.90, update your firmware first then compare your battery stats from your previous firmware version.
How long is your SoT(Screen on Time)? Well, on a daily usage my Zenfone 2 lasts for up to 6hrs SoT(with wifi browsing, some gaming, 2g/3g texting including standby for almost 12hrs as well) so i think your experiencing average for this kind of handset.
Also note that you've posted on a wrong section, this thread should be posted on the "Q&A, Help, Troubleshooting section".
This phone generally has **** battery life for majority of people, there are every few people who see any decent battery life (like above). There are no solutions for good battery life for this phone.

I wouldn't recommend somebody (even less a new XDA user) to flash a beta firmware. Only the user itself should decide if he /she really wants to try beta software.

Comparing this phone's battery to a Huawei battery is like comparing a Prius to a Tesla. I can go 3 days on my Huawei Ascend Mate 2 but it's a 4000mAh battery and a Snapdragon chip compared to a 3000mAh battery and an Intel chip. The ZF2 battery will never get better unfortunately
I was getting some serious battery drainage on stock rom - I upgraded to the CM13 ROM with Android 6.0.1 - Set it on Root and installed Greenify + Xposed Framework - Smart Booster - Battery Doctor - Configured them all and keep my brightness on low when in doors and automatic when outside. My battery seems to be holding much better now. I haven't used that Stock rom Beta release of 6.0.1 yet so I'm not sure if that'll help. Good luck!
P.S - I only installed the mini version of GApps.

Check for the running apps and disable those that are not of use to you.. There are apps that run in the background, just run those that you think you will be using always.

Disable touch gestures, the ones that let's you double tap to wake it up, I disabled mine and during the night, with wifi on, it only used 1% battery.
Also, disabling LED notifications would help.
To replace the double tap to lock screen I use Greenify's widget, need to find a way to let me wake it up by volume buttons too.
Any other battery saving tips would be great.

zenfone 2 is best for performance lag free most of the time .....but battery life sucks.... and about that ferrari and prius thing... my friends sony xperia z series especialy z ultra has awesome battery life it is also quad core processor phone ...it is also a beast phone ...but there stamina mode saves a lot of battery ... 8 to 10 hr SOT is normal for z ultra..... so clearly power managment is very poor for zenfone 2. i am using marshmellow cm 13 .. greenify... .. overnight drop is 3 to 4 %... but as soon as i start using it battery starts to drain quickly..... i have searched whole xda forum.. but everybody is talking about wakelocks, thats fine but during actual use also it is consuming a lot of battery....i am tired of searching

Axon 7 A2017G Android 7 Battery drain

Help...
The Battery drain is too much... how to fix it?
Everything was doing great in android 6.
how can I downgrade to Android 6?
Which version are you using?
If you use the beta 7.1.1 then don't post bugs like yours.
Wait for final version.
Before that do a reset and test your phone again.
Otherwise look also for apps like wakelock detector or better battery stats in its alarm section.

I just updated my ZTE Axon 7 (128gb Internal Storage - 2nd resubmitted) Android 7.0 to Android 7.1.1 and now, my battery is RAPIDLY DISCHARGING! EVEN WHILE ON THE CHARGER! I wish I could revert back to 7.0, but I fear that cannot be possible without performing some sort of technological gymnastics and a Pagan Ritual. I'm really stressed, here.

Maybe some issue with your signal or configuration, because with my phone I can get easily 4-5 SOT and at least one day of usage with everything synced, WhatsApp, 3 mail accounts, GPS, Google Now, etc.

Yeah signal is a big battery drainer, I have low signal in my home and my battery drains like hell, I always keep the phone on charger when I'm here lol.
Once I'm outside though my battery drains much slower.
Fricking network providers and their weak ass antennas, haha.
I don't even have a SIM card in. I just use the phone for gaming.
I probably have something wrong with my unit, becouse it seems like the battery is perfectly calibrated on 7.1.1 and no draint whatsoever, today managed 6h of sot, with some antutu, youtube, play store downloading, 4g+ and snapchat going on. I mean now when i lock the screen on certain % it stays, but on mm it dropped 2-3% after locking

I have the same experience, is going really good so far.
Hmm time to refresh old post.
A2017G B04 full stock.
Since I got B04 my SOT dropped from ~5h to 2,5-3h. BTW. I already tried factory reset, cache cleaning from bootloader - no positive results.
Same with mine... Some reported it's due to bad cell signal is causing battery drain

L29C636B585 Best Nougat version

Like most of you, I have been complaining about excessive battery drain in nougat versions. After trying different roms and going back to Emui 4.0, I came across C636B585. This version have quite a great battery performance (even better than Emui) and the fast charge came back, (it had disappeared in other Nougat versions) finally I have a great battery live in a Nougat version, and the device feels smooth as butter. Definitely worth giving it a try.
I debranded and then got the update using proxy and the firmware finder.
Now if only there was a working way to get it on AL10C00
would love to try it
@juanq214, do you know how can I move from cm-13 custom ROM (lineage os) to L29C636B585? I don't want to brick my device so would like to avoid trial and error methods. Any help / links much appreciated.
IS it better than al10 b589? ^^
I have this version and did factory reset etc. I still think the battery is poor in comparison to pretty much any Marshmallow rom. Max SOT I get is 6-7 hours, but it's random sometimes I get less than 5. With MM I'd typically get around 9-10 SOT.

thats the 50.000 dollar question here im betting B589 has the same base, if not newer, so debranding an AL10 to L29C636 just to try this rom wouldnt make much sense in my eyes
guys, i will tell you this one more time: depending on the apps ure running, the sensors u leave switched on (BT, GPS, Wifi, etc) especially when not in active use, screen brightness, standby time, number of calls made, data type (2G/3G/4G), etc your SOT values will differ by A LOT even on the exact same firmware and configuration!!!
example: on days when im at home / permanently connected to a wifi (all other sensors and mobile data switched off), i usually get around 9-11h SOT.
however, when im on the move with mobile data switched on (3G), using GPS for navigation and making calls, then my SOT tanks to around 6-7h. thats both on the same firmware with same settings, same apps installed etc.
so, if you REALLY want to compare battery life between firmwares objectively, ull have to do the following:
install firmware, leave it stock, dont change any settings, switch on wifi, BT, gps, mobile data, make sure the screen stays switched on at a defined brightness level (not automatic but static) and make sure u dont get any calls or messages, otherwise that would again change the battery life.
do that for every single firmware and u got urself an objective comparison of SOT values
personally, no matter which firmware i was on so far, i always got more or less identical SOT runtimes: around 9-12h on less intensive days and 6-8h on more intensive days. thats it, and it hasnt changed going from B112 to B357 to B575

Well, in my case I have had 5 different Mate 8 devices, so I am quite familiar with this device. Like the previous comment points it out, it is quite difficult to make an objective comparison between different filmwares. However you know your device and you can tell when it is consuming more battery than I should. Before this version, I was running L29C432B585, and you could see the battery draining in from of your eyes as you used the decide, it was just unusual.
I am a heavy user, (Bluetooth for my smartwatch, GPS when driving, wifi modem, switched to 4g often, etc) and still can make it to the end of the afternoon in a normal day without charging. That's fair enough for me. Also you must take into account how old your device is, and batteries get older, they lose mha capacity.

Can confirm this. I have no problem getting over 10h SOT when one wifi. This phone is very efficient when not on mobile data.
Huawei radio sucks a lot. You can see how the phone gets hot with intensive Internet use on mobile data while it stays cool when you do the same on wifi.
I'm wondering why all these updates get sent out to some, but not to all Mate8 users?

depends on your cust (internal regional code) and im guessing they send out the updates in waves to check to real life applicability (no bugs, stable, etc)
also, lots of people here just update manually via firmware finder or dload method

Not that I'm aware of.
Sadly the battery drain came back... From yesterday afternoon the battery has been draining at an unusual fast pace, strangely the fast charging feature is also gone.
So it seems it's something that comes and goes. Since I flashed this rom, I had used the phone for about 1 week without battery issues. I wonder what triggers this behavior In the device? Yesterday y didn't do any unusual stuff apart from installing a couple of apps.
I'll have to end up selling my device and sticking to a different brand. Definitely Huawei produces great phones with really poor support and almost no development. I'll keep you posted.

the support is actually great for the mate 8. here some statistics: from october 30th, 2015 up to the most recent firmwares from july 21st, 2017, a total of 595(!!!) full firmwares and OTA updates have been published on huawei servers for all variants of the mate 8. that time span is equivalent to 630 days, so we have 630/595 equals
one firmware published every 1.06 days or 25.4 hours on average!!!
could anyone call that bad support?
besides, this battery drain issue some users face here sounds VERY much like a settings / installed apps problem to me, especially since it just "appears" suddenly when "a couple of apps" are installed, very curious indeed

It doesn't make any sense to release updates if they come with lots of bugs and you have to wait for a miracle to receive Ota or push it yourself by debranding or other methods. I wish they released a stable Nougat version.
Regarding the apps installed, it's just impossible that common apps such as Twitter or xda app could increase battery consumption that much. I have had more than 4 different Mate 8 devices so I kinda know the device well and for sure this battery drain has to do with the rom.

How to downgrade my firmware?
I have an original L29C636 on B585, I want to "downgrade" back to a previous ROM, anything before B585, I couldn't find a way to do it, please help
two of my friends also having a stock L29C636 and they both said after updaing to B585, they have 20% less battery and phone freezes for a sec here and there sometimes. So they are just normal users and they use the same app, same way, so there might really be some battery drain issue here.
Thanks

Issue??? Most of time, battery drop 1% after i unlock phone and use it a little

Hi people!
I cannot complain about battery life, specially in stand by (i rarely active use the phone), with wifi always active and during day time whatssapp web active in background, after root, naptime to force doze and other optimization here and there, my battery last till 6/8 days (with little screen time, 10/20 minuts/day), lol.
Problem is the screen use a lot of juice, even if i set up brightness around 55% only.
And, more strange, i lost 1% of battery almost all time i unlock the screen and use the phone a little.
I mean, i unlock for example the phone and im 80% battery, in 20/60 seconds will turn to 79%.
I unlock and use a little when is at 56%, after 10/30/60 second, turn to 55%.. and so on...
This happen most of the time i unlock it to check screen and i play around a little checking apps and doing stuff, but no games or heavy apps.
Im in last January oreo patch.
Is a common "issue", if issue can be called?
Is a behavior other mi a1 phone noticed too?
My phone was behaving like this also before root and before use naptime.
Facing same issues
I have notice this too but also 1 restart cost 1% battery life is this normal? So if I continuously restart phone 5 times it will use 5%, is this like this for other phones too I'm not quite sure?
I don't have such issue, I turned on/off 6 times with delay for about 60 sec and it dropped only 1% the first time, and I keep the screen brightness about 70%

OK but this seems more a issue of your phone, not a general, operative system base, battery drain.
And your issue dont have similarities with phenom i described in first post in this topic!
You must check what app/setthing keep your phone awake while in stand by and fix it.

Just go on MIUI Forum.
Mi A1 subforum.
There's a lot of posts about battery drain.
It's not an issue of my phone.
AND it's battery in your "phenom" too.
Or you have a damaged battery.

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 Xiaomi Mi Note 10's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
standby drain is bad for a 5kmah battery
Such a huge battery drain for me too. Which forces me to recharge the phone when I wake up in order to have a full battery.
Check the CPU frequency. Sometimes it gets stuck over 1248mhz at idle. You have to reboot the phone to get it back down to 576mhz.
There's an app in playstore called "CPU Stats". That app puts a CPU meter in the status bar. Handy for letting you know when to restart
Not sure if thats me but i think ive noticed a drain by GSM, same issue that was on my mi 9 with global rom. try to go to service mode from dialer *#*#4636#*#* and set connection type to LTE/WCDMA seems like its helping at least a little
This became a common Miui issue these days. Had this problem with my Mi9T also, and couldn't resolve it in any way, maybe only by flashing custom rom, but this is not a solution.
Usually it was "cell standby" or "whatsapp" that was draining the battery...and I tried everything, debloating, battery optimizations, network mode changes etc.
I have the same problem. Yesterday I used the Mi note 10 intensely. I did 7h of screen and he was still 40% when I went to sleep. Today when I woke up he was 24%. It drained 16% without any use. I have to find out what is draining so much in Stand By.
I'm sad i'm selling my MI NOTE 10 to whom staying in Côte d'Ivoire (Ivory Coast)
If you are in Europe, just apply the 11.0.16 Ota, if you are coming from 11.0.13 global stable. It fixes the battery drain. Download and install via the updater app.
Download from here: mirom.ezbox.idv.tw/en/phone/tucana/
I was becoming very depressed about this, just got my phone 2 days ago, and the battery was very poor... Hope it helps!

My drain was pretty minimal before updating to the newest EU Rom, but now it's much worse.
So not the same experience for everyone I guess.
I guess not... Not really sure what's happening. Waiting to 1 more day to unlock my bootloader in order to install globe ROM (android 10). It should improve battery drain and camera app... Let's see...

Can't really risk that with SafetyNet being seemingly impossible to bypass in the future.
With magisk it's fine, I think...

Well for now, but the tools are in place to completely break it, they just have to flip the switch. Which will happen sooner or later I'm sure of that and not passing Safety Net until some finds another exploit (which can be months) isn't really an option for me.
Wakelocks has been a constant issue for me on MIUI for years with bad standby as a result. This phone is no exception. It was bad on EEA Global ROM. It's bad on Android 10. I love Xiaomi but for the love of god it always has drain issues in standby. 1% per hour is not OK on a phone like this.

I confirm this, the cpu usage was stick around 60% at 1.2ghz, without doing nothing. The reboot fix this, but what cause this problem? This phone 2 days ago get an hard reset.

I'm not sure what's causes it. It's either a kernel issue or a system app within MIUI 11
It still happens with the latest 11.0.9 update
Hi, any heating issue with drain, during videocall or web browsing with this Mi Note 10 (Miui Global Stable 11.0.17)? I'm from EU. Thank you!
after the Update to Global 11.1.1.0 Android 10 seen great improvement in battery life and standby drain. Dont know if its only me.
