Hi all, I have just updated my Vivo X70 pro + to Funtouch OS 13 from the Trial version option from the system update options. Once the update was done, the first thing I noticed was the temperature of the phone which shot up and all the things were stuttering to run smoothly for around half an hr straight which made me want to downgrade the OS again. But now it is running smoothly.
But I would love to know a way to downgrade it.
Also, the battery on this phone is just disappointing just after a year. It gives me around 4-5 hrs of SOT and I end up charging the phone for 2-3 times a day. Please let me know if anyone else is facing the same issue and if anyone has found any fix for the issue.
I have done the uppgrade to and i have non problem , all it just good and the best is that VoLTE is included i bought mine in april , the battery is just fine , it holds like 2 days
Damn... Mine drains even when the screen is locked. It's 33% less in the morning after i sleep. Is this normal?
Can more people give me some reviews for the battery?
Also, just got an OTA update and my phone seems to be working perfect again
how did you downgrade?

Hello, I have a Moto X second generation XT1097 (from Brazil). And I received the update to lollipop recently. For a few days it was ok, but then it started draining battery like crazy. I used to get at least 16 hours with 4h30 of screen time, and now I am barely getting to 10, with less then 3 hours sot. The other people with this version of the phone here in Brazil didn't get this problem (according to motorola forum owners). My phone is not rooted, and I don't want to root it, because I heard I will lose the warranty. I downloaded Gsam battery monitor to try and find out what's the problem, and apparently the biggest drainners are kernel and android OS (16% and 10% respectively). I've searched a lot of people with similar problems on the internet and tried to factory reset it, (and reset it from the recovery too, if that makes any difference. Even without installing the apps it drains very quickly). I also tried updating the play store app manually, as apparently that has helped some people. Still nothing. I'm keeping the wifi off right now, and GSAM indicates the battery decrease rate got to 0, but got to -10%/hour again after some time. Can someone please help me? I've read something about static and dynamic IP, that might cause this, how can I solve that? And if I solve it, that menas that it will only work for my home wifi? Because my university's wifi doesn't give me any better battery either. I'm almost about to return it to the manufacturer, someone please help.
Facing the same issue. Did not factory reset yet.
Is yours XT1097 too?
The factory reset doesn't really help at all...
hi hope someone can help with this.
I have a huawei p9 32gb EU version
model EVA-L09 emui 4.1.1 (still on) android 6.0 (says no update available)
build number is: EVA-L09C432B182
An issue seems to have developed in the past 2 weeks (i've had it almost a year) - it has decided to close itself down when I try to use the camera. I am using the default/stock camera app not a 3rd party one. I want to make clear it does not happen every time seems (at the moment) quite random/intermittent
The battery was at 79% the first time it happened and a few days ago it was at 55% and it happened. Auto flash was on but flash not activated at the time the phone shut down.
The first time I thought I just hadn't realised the battery was that low but when I plugged it in to charge it said 79% on screen.
A few days ago when it was 55% I was able to put the phone back on after it shut itself down and it was fine/behaved normally since putting it back on - the battery appeared to drain at the usual rate. I even took a few other photos after switching it back on & it didnt shut down. I had been using camera the same morning when the battery % would have been higher & it didn't shutdown then. (& i actually took quite a few photos during that time).
Hope someone out there has an idea of how to fix this issue, though i'm thinking its maybe the a sign the battery may be failing?
I also have this issue, I think it may be a sign the battery is beginning to fail, or possibly the cpu gets too hot. (again first started happening around a year into ownership)
Under 70% battery if i take a bunch of photos it can shut down but would normally turn back on again with 20% less battery. if battery gets less than 50% then if it powers off, it may power back on breifly and then go back to the exclamation mark for empty battery and shut down.
I have tried following the guide to calibrate the battery (let it charge to 100%, turn off, plug back into charger) but it made no difference.
What did help a bit though was ensuring cloud photo apps (google photos/onedrive etc) were set to only upload photos while on wifi and charging.
Hi, I have the same issue with my EVA-L09 with EMUI 4.1.1 build EVA-L09C900B182 bought in october 2016. Shuts down after shooting few photos/videos and can't start it again without plugging it. Once plugged, the battery level seems to be the same as before the shutdown. Seems to happen with any battery level.
If anybody can help solve this, that would be great. I can't decide to change the battery for the moment without certainty that it would fix this issue.

To all of you...unlock bootloader and update firmware. Maybe your issues will be solved. Its a conflict and not a battery issue
Sent from my EVA-L09 using XDA Labs
Any resolution?
I am having the same problem with my L09 and the P9 camera app. Was on Nougat so rolled back to MM in attempt to fix. Also tried a faster SD. No luck with either.
No such issues with other camera apps from Play Store, but they don't use both sensors.
Anybody resolved this problem definitely yet? If yes, how?
Thanks.

I have the same problem since the last 6-9 months.
However I noticed that the problem occurs when I make photos when I'm outside and the weather is windy/damp. I never had the problem when shooting photos inside, always outdoors.
The solution is indeed connecting the phone with a charger (or portable battery) or wait for a couple of hours.
It could be a problem with the battery but it is strange that the phone is ok again after charging a couple of minutes. If it was moisture this idid not yet vanish in just a couple of minutes. Maybe a sensor which is not working ok (or the firmware is not resetting/reading it correctly) ?
I'm thinking of sending my phone into repair for this problem, however I think this is a difficult to identify problem because it does happen randomly (as it seems).
I'm having the same problem, after battery goes under 50% It drains fast, bellow this it only takes 30min of use to shoot down, taking a few photos just makes it drain even faster. And when plugged to the charger it suddenly gets up to 40% . I tried everything software wise with no luck. I bought a new OEM battery planning to change it this week, then I'll post the results.
I am facing the same problem L09C432B395. I observed its somehow being related to cold temperatures outside in my case - it happens only when walking outdoor and the phone is in my hand for a while - so its probably cools down. And than when pressing the camera button I see the message "waiting to sharpen the photo" and then beeeep! battery down to 1% and phone shutdowns. Regardles the battery level.. happening accidentaly and randomly, but only once a week.. and only when taking phone outdoor in a winter time. I did factory reset, re-installed the latest ROM etc but the problem persists. Might be some conflict between battery state and temperature read error?

Update: I change the battery, everything back to normal. I used a OEM battery, screen time is +6h with moderate use during the first row cycles of battery use from 100% to 10%.
Hi all together. Faced the same issue up times (Huawei P9 EVA-L09C432B395, Kamera App 4.1.1) with battery in good state 46 to 76% and taking a picture caused draining it to zero at a moment. Sitting down immediately. BUT only if flash ? is set to bulb-light ?! Tested it several times. Normal (auto/always active) flash is ok - but not bulb-mode...
So, that's obviously the reason - but where's a solution? ?
Some Huawei officials here at xda? ?
Same problem here and without solution yet ... camera causes phone to shutdown and battery indication goes crazy.

Experiencing the same issue on both P9 we have and getting very annoying would be glad to see if is there any solution of this.

These are my exact symptoms - combination of cold and camera gives false battery reading and shuts down phone entirely. Software update hasn't fixed.
I have same problem
EVA-L09C55B383
it's the last firmware
emui 5.0.1
android 7
at 50% battery i make a photo with flash and the p9 turn off.
to turn on i need connect it to recharger.
it's very very impossible.
i think to send it to customer care.
have someone resolved this issue?
i ask to huawei on facebook. i wait a answer.
Any luck with Huawei support for any of you?
Hi,
I'm having the same problem. It's amazing how there's no information at all from Huawei about this issue... it's frustrating. I was planning on buying a P20 during this year and give my P9 to my wife, but if she can't use the camera it's useless. And I will not buy another Huawei if they don't do anything regarding a problem like this one...
Did any of you had any positive experience with Huawei Customer Care?
Thank you!

Did you try yourself any search for custom ROMs ob XDA for Huawei P9?!
https://forum.xda-developers.com/p9/development
I tried Huwawei customer care.
Their best offer was factory reset of all firmware!
Install updates doesn't fix.

Even when connected to charger!!
Even when the phone is connected by USB to my computer and charging, if I open the camera the battery % starts to drop like 1% every 4-5 seconds!!
So the battery is being drained faster than what it charges.
I close the camera and it starts charging again.
Huawei, I was very happy with this phone, now I'm constantly in fear of getting out of battery in the middle of an unknown city while taking photos!
Hi guys, has anyone else been experiencing poor battery life in the stock note 8 oreo rom? I've factory reset, switched off AOD etc. Same apps installed as when it was on nougat.
Thanks
Mine is doing the same. I reckon it will take a week or two to level out

i agree mine used to do that on nougat
I also have terrible battery life.
I've switched AOD off, as well as the weird Gallery settings (like Image Analysis etc), but it's still losing 30% battery while sitting idly for 3 hours.
I hope it does level out soon enough.

Maybe some of those apps aren't as optimized for Oreo yet. In any case, let it settle for a while after a major update like Oreo. I got over 5 SOT with my regular usage (27 hours runtime) on my first full charge after updating. Not bad, but it will improve a bit from there on my next 1-2 charges and hit 6 hours SOT like before.
I recommend you install betterbatterystats, give it permissions through adb, and let it run. Post some screenshots from the summary, kernel wakelocks, and partial wakelocks tabs. It'd make it easier to pin down the issues.
Okay guys, so it is the third/fourth day now and battery life has gotten better. This morning I did wake up to a bixby update, so maybe that was the issue? Anyways hopefully the battery life stays like this ongoing.
As soon as OEM unlock comes up I'm flashing a custom ROM ;P
So, It has been 10 months of headaches. Bought in july 2019, for two months best phone ever, battery lasted 2 days, near to 1-2% of battery drain at night on standby. After installing miui 11, the battery said "bye bye". 3h screentime, need to charge the phone twice a day, losing 10%/h on standby.
What I tried is:
-havoc os
-xiaomi.eu Miui 11-12. beta and stable
-Evolution x
-latest firmware always/reinstalled latest firmware-vendor
-always clean install wiping everything
-new battery 2 months ago (same results, no difference at all)
-no app is draining battery in the settings
-unistalled analytics and miui daemon (msa not found on xiaomi.eu roms)
the phone goes in deep sleep as you can see in the photos in the link below.
Gps, wifi and bt always on. Tried switching them off, just 1% less of battery drain on standby.
Bought a broken mi 9t pro just to try switching motherboards, just to try that it isn't a electric or physical issue with the phone, but can't do it that right now, waiting the new screen to test the broken phone.

Any suggestion?
Have you tested putting the phone on standby in airplane mode? This is unlikely to be the root of the issue but poor cellular signal may negatively impact the battery life.

tried that also, nothing change. Always 4%+/h of drain in standby.
I've pretty same problem, and it's really strange...
I've a Mi 9T Pro, bought not more than 2 months ago brand new, all stock.
I leave on just the phone active during the night, in both SIM cards: no bt, no wifi, no mobile data active.
The battery drain is around 10%, which is really insane considered that before my 3 years old phone, an Honor 8, in same conditions, was draining not more than 4%.
In general battery is draining really too much.
Passed OTA from MIUI 11 to 12, but the drainage is same.
I'd like to understand what is the issue causing that.
Dude. Same issue for me. It's only 6 months old. I noticed battery loss on miui just a month into purchase. I'd suggest pick a rom without Gapps or one with microG and try them out. I was using evo X and getting around 6-7 hrs SOT. Once I moved to Aim and Omni I started getting 9-10 SOT. I think Gapps is mostly the culprit. Miui sucks these days. I tried miui 12 and was utterly disappointed. Try this and you might just start loving your phone again. I'd say go for Omni and setup microG, install greenify, turn off battery optimisations only for essential messaging apps and turn on aggressive doze. Your sure to see a difference
Try havoc os 3.7 , try it without social apps like instagram, facebook and other crap.
Mine usually lasts around 3 days with 6h sot.
I also have gps , bt , sync and data always on
Tried gms doze? Disabling autostart of apps in miui?
Mi 9T Pro ll Tapatalk
The point, guys, is not to try different ROMs or install apps or not to use social medias because the phone drains battery...
The point is that the phone should not drain battery that much at all!
I think Xiaomi should care more of the firmwares released, trying harder to fix bugs that might be important rather than releasing new features.
My own opinion.
PS. Last night i checked the battery drain thoroughly: from 1.30 am to 7.30 am, just both SIM cards on to receive eventually phone calls, no WiFi, no BT, no internet connection, ND mode active = battery drained 9%
It is not acceptable!!
Clear all apps from memory, clear cache of 'Google Frameworks' and 'Google Play Services' don't restart the phone
I do this whenever I remember usually every few days and get great SOT around 9-11 hours. Although Accubattery says my battery health is 3300 of the 4000 as I've had it for a while and I'm a very very heavy user. Brand new was getting closer to 10-12 hours doing this same method.
I found it by someone posting a random comment somewhere in this forum just don't know who or where I saw it. They gave no explanation as to why it works but just what they did and its worked immediately. Note I'm still on MIUI 11.0.3 Global as I'm nervous this method won't be as effective in more newer MIUI Versions.
If you have a newer version please try and let me know if it still works, hope this helps
Also I reinstall MIUI through the phone after clean flashing it via Mi Flash
That is that I flash clean (erase storage but not lock bootloader) from Mi Flash and then go to the update settings of the phone and then press the 3 dots at the top left and "download latest update" and then install it again
This helped when I was on MIUI 10.X.X but do it out of habit so not sure if it helped for MIUI 11.0.03
edit: Reinstall method
Similar issue with my K20 Pro.
1. The battery backup on Android 9/MIUI 10 was giving me close to 1.5 days of backup of 7-8 hours of screen time.
2. It was decreased to 6-6.5 in Android 10/MIUI 11
3. Now with MIUI 12 it is reduced to 6 hours and with need of charging two times in a single day. All this with no social media apps, only Whatsapp, Youtube, Prime Video, Spotify and MS outlook, teams apps with regular usage. WIFI all the time, no GPS, 2-3 hours of Bluetooth. plus tried deboating MI apps.
So far I have tried PE, EVOX and EU roms but all gave me disappointing battery backup. The battery seems fine only on android pie so my assumption is that battery probably doesn't need replacement and more of xiaomi's firmware related issue on android 10.
It's so disappointing to see such a great piece of hardware holding back because of battery. I hope somebody find a good solution to this issue.
I've promised myself not to root my pixel NOR install custom ROMs or kernels over the stock and for 1 year almost I kept the stock ROM on. It feelt wonderful to find a stock phone that was so smooth and an incredibile battery life then...
Well, then Android decided to update to 12 and I felt so confident ( usually I don't update software on old hardware ) and trust Google so much that i did the update bit **** starter to happen. Battery was draining faster then ever, with the same usage of the phone it went from 100 to 0 in 6 hours. Tried it for 1 week, factory reset twice and started from 0 with no apps installed but nothing changed.
Does anyone else had the dame problem with Android 12?
Btw, now I al on LOS + Sultan Kernel and in 13 ours of usage ( the same ad always, i don't use the phone to much ) I still have 77℅
I have the same issue as you! Besides that, A12 works randomly face id on my phone. Then I decided to use LOS
@MySelf_v1
Glad you found a solution, but I have no issues with battery on A12 running the stock ROM. That being said, Google has replaced my phone twice due to defective batteries. My current phone shows 3,860 mAh capacity which is 104% of the design capacity of 3,700 mAh. I have used Accubattery for years (after the 6P battery debacle) and when the battery capacity dropped below 80% on the P4XL I was on the phone with Google straight away. Most of my problems on the previous P4XL's were from using wireless charging continuously and leaving the phone on the charger all night, charging to 100% every time.
