Hi Guys, got a Problem.
I've got my S2 now for about 4 Months. Normally the battery holds about one day possibly 2 days with about 4-8 hours of phoning. Now the last week when i began to flash infusion rom with different modems, my phone first day holds the battery about 10 hours, next day 8 hours. I flashed the Criskello Rom tested again, again 8 hours. Then this weekend it holds the battery about 4 hours and while calling, the phone doesn't respond to anything, or sometimes the display keeps on, only holding the power button let's it restart. While charging i'm not able to start the phone, the charging symbol displays but when pushing the power button it restarts only to the battery charging symbol. first after unplugging the charger i'm able to boot. Android OS is 52 Minutes in 3 hours now. But i'm not able to locate where's the problem. every time i flash a new rom i format everything, data, cache, dalvik , system etc..... sometimes when i'll have to restart the phone very often and put the charger into it, it displays my battery with a temperature warning 80-100° C
Today i ordered a new battery while hoping the battery is dead, but really no other idea.....
and another effect i was wondering is suddenly the display lights up, goes off and then keeps lightening.....
and what i was wondering is that since this moment the phone doesn't connect to usb. when i put in the usb plug it starts loading but when i remove the plug it keeps loading with having power.....
No one an answer???
Personally I'd revert to full stock, wiping all and see if it's still acting questionably.. If so, choose your kernel/rom combinations more carefully..
Also I had some battery warning issues when my usb pin got slightly bent, weirdly. Check that out.
today i wiped nearly everything including emmc sdcard and flashed oxygen and the handy works. but android os is at 5 hours of 2 hours runtime.... so it uses the complete cpu time of both cpus fulltime. now i bought a new akku now the handy works better but android os is at the same....
Sorry i fail to understand the problem as posted .
When you flash multiple roms etc you need to recalibrate the battery .
But this looks like a service centre job .

Hi people, nexus 6P owner since 2 years now. I remember when I received the phone I could reach without worries 5 to 6 hours of Screen but then, after nougat and now Oreo, I've never achieved again that numbers.
After rooting my phone, flashing carbon rom and installing elemental X kernel, I played with governor profiles and improved my SOT a little over this year but it was getting worser and worser by every day (2 to 3 hours of screen on time and heavy idle drain). Finally, the real problem came the other day when for the first time my phone shutdown at 29% suddenly after opening the camera.
So I read internet and found in the nexus 6 (not 6P) forums that someone suggested a solution concerning a problem with how the phone meter the battery remaining, suggesting doing a series of steps of charge discharge that I will list here. This, and changing to ABC rom may have done the trick, as now I'm getting much more normal battery life (considering the degradation of 2 years, 2700mah left approximately) of 4, 4 and a half hours (yours will be better) SoT and an idle drain of less than 0,5% per hour, and apparently it didn't shutdown early anymore.
So, give this steps a try if you tried everything like I did and you still having problems with battery drain.
STEPS THAT MAY SOLVE EARLY SHUTDOWN PROBLEM:
- Charge your phone to 100% and use it until it shutdowns (look at what percentage).
- Boot to recovery by pressing power and vol - button, and once in there let it drain the battery until it shutdowns by itself (may take a lot of time so increase brightness to maximum in the recovery menu under settings to consume it faster).
- Now it has really reached 0% and if you try to power it on it won't let you by blinking red in the notification led.
- Plug the charger and leave the phone off until the battery indicator show it's full.
- Unplug it and turn it on, it should show you the battery at less than 100%, like 95%, 90% or even less depending on how bad it was calibrated (mine showed 95%).
- Plug it to the charger without turning it off until reaching 100% and only then unplug it first and then turn it off quickly.
- Plug it one more time (off) until the icon shows it is full and then unplug it and turn it on, now it should say a number closer than before, like 98% or 99% (mine was 99) or it may be 100%. If it shows 100% then you're good to go with the calibration, but if it shows less, repeat the process by letting charge until 100 and then doing the same steps as before until you turn it on without charging and finally it shows 100% battery.
Please report back if this steps worked for you, because for me I think it made the trick.
Now for the battery drain what I did was this steps,
STEPS THAT MAY STOP THE POST-NOUGAT HEAVY BATTERY DRAIN (android OS drain, etc):
-Unlock and Root the phone
- Install ABC rom (check the post here in XDA)
- Flash ElementalX kernel (also here)
- Install the app "ex kernel manager" from the play store
- Enter settings and disable printers (you still can enable them if you have to print something)
- Install Greenify from the play store and select all the apps that don't use notifications.
- Uninstall unnecessary apps that you don't use anymore.
- In the Ex Kernel manager app go to CPU -> governor options and select "load". Choose one of the following recommended profiles: Excalibur V2, Dragon Fly v1, Butterfly or DeadPool. (Or check the guide in XDA about governor profiles).
- Finally activate the run on boot option and reboot to recovery, wipe dalvik and cache and then boot into system.
If you have luck like me, your phone will run very smooth and battery life will be normal to it's current degradation. My phone now last me all day like before and I don't have to charge it twice or three times like I did and best of all, when I don't use it, it almost don't lose battery (2 to 3% overnight).
Also I've never seen again that android system process consuming the same amount as the screen!
I hope this serve someone and maybe save some phones too , I never resigned my 6p because it's a great phone with one of the best cameras out there even today and with great speakers too.
Please let me know if it worked for you! Of course I don't promise it will, but you have nothing to lose anyway! Good luck.
Pd. Sorry for my English , I'm from Argentina
UPDATE: Today my nexus shutdown at 10% but only because I opened on purpose the camera to check if that is the problem, and aparently it is. I've read that when then phone has low power, an app that consumes a lot of battery like the camera may cause shutdown to prevent the phone damaging internal components. So no fix for that at the moment, just don't use the camera with low percentage.
Hi, I don't know if this thread is still on but I'd like to say that I had the same issue. I have a Nexus 6, as you said, and I've installed on it the Resurrection Remix ROM (Neo version). After that, the phone suddenly shut down everytime it reaches 20 or 30 %. I tried two solutions they suggested me;
1) In bootloader menu, go on bootloader logs and press start button for 10 seconds more or less (when you get Google logo and the phone actually boot)
2) Try to reboot the phone in Safe mode and then back in Normal mode
I've also tried to calibrate again the battery (maybe I did it wrong); I followed a guide on it but I can't remember every step of it (if interested I'll try to find it again). Nothing worked, the phone still presents the same issue and I really don't know what to do. I'd like to try this too hoping it works otherwise the last thing I can do, I guess, try to flash again the ROM. Do you have any suggestions? Thanks so much
P.S.
The battery works PERFECTLY; before I flashed the ROM it worked so damn good so I really can't believe that it needs to be replaced, I know that the phone is really old but it always worked fine so it's more logical presume that the problem is with the flashing
Using Stock Nexus 6 Shamu Kernel, with last TWRP and RR OS
Just replace your battery - you might think it's the flashing etc, but at the end of the day my money is on your battery just having called it day, which they can do quite suddenly.
I found that once that early shut down starts it gets worse quick.
It's not that big of deal to change out on these phones anyway and if you do it yourself it's cheap (15 dollars or so). - I've just done it for the second time, not that I was having early shutdowns with my first replacement but after about 18 months life was starting to wane.
Just sharing my experience with my nexus 6p.
Early shutdown problem sure gives us headache. Already tried several methods like calibration, reflashing to factory images, downgrade to minor build or major build, none of them works.
The only solutions that works for me is replace the battery, only cost between $10 to $20 for me (it depend on type battery that you buy, mine is OEM one)
Hello, giving a try to the OP guide regarding early battery shut down. Just a quick question - how long does it take for battery to drain out while in recovery mode? Screens been on for like 2hours now, I see top right screen corner the battery % completely disappear, but recovery still usable. Just wonder, how long it will take for phone to auto shutdown while in recovery mode?
And if this does not work, I'll just replace battery, like @reintakura wrote above.
This device is a disaster. Does it really work?
I tried this the other day. The phone shut off when the low battery came on. I kept powering it up. The first few times it shut off immediately. The next time it turned on and said I had 10% left. Let that 10% run down, it powered off. I kept powering it on... it would boot. I did this maybe 50 times, every time it would boot and then shut down. Then the last time it got "stuck" on the Shutting Down screen. I let it sit like that for a good 10 minutes. It never powered off, it just was stuck on the shutting down screen. I held the power button down to initiate a hard shut down. Plugged it into the charger, device off. Screen said it was 100% a few hours later. Turned on device, device reported 100% used it until it got to 70% and then the low battery light came on and it powered off. Let it charge overnight with device off. Right now it's slowly losing battery, I'm at 76% and it hasn't shut down.
Strange stuff going on.
i was facing the same problem, two days ago i returned to 8.1 abc rom
i'm getting 4h sot and no early shutdown
I can't believe I spent $200 on this **** phone and waited 3 years to get it thinking its the best thing since fried rice, mine started shutting down at 20-30% now it shuts down anywhere from 30-85%!!!!!!!! ahahahahahaha in the end its my fault for buying refurbished, someone obviously sent this crap back already and they did nothing to fix it and conned me into buying it.

Hi, there. This reply is way late, but I've been away for years and I've only now decided to come back, so I'm necroposting on everything that's relevant to me right now. I hope that's not a serious offense.
I've had my 6P since August 2016. I bought it NOS from Google Fi at a slight discount. It worked like a charm for me for years until around winter 2018/2019, when it started shutting down in the cold. I figured that was understandable. I bike a lot, even in sub-zero temperatures, and I tended to keep my phone in the breast pocket of my windbreaker.
It didn't care too much for that.
So, I started putting it into my backpack and it stopped shutting down.
Then, this summer (2020), the battery went off a cliff. It's been dying anywhere from 80 to 10% since June. Maps and the Camera are the big killers, but the battery will plummet from literally any use.
Yet, it will idle for days if leave it alone.
I recently decided to just wipe the thing back to factory and see if that solved anything. It was quite a feeling to scuttle all of my SMS (I backed them up to my Google account, but it seems like they've gone to some mysterious corner of the Internet from which they cannot be retrieved. Alas). It was kind of a catharsis to throw it all away.
I did back up all my media, however.
The factory reset solved nothing, so I tried the OP's recommendation. I loaded into the bootloader and, instead of waiting on the primary screen, I went into (stock) Recovery (my phone isn't yet rooted) and ran the display test a bunch of times. I alternated between that and selecting "Barcodes" since the all white screen is a bigger drain on the battery than the black and green default.
Eventually, the thing died, but it took hours. This, despite that it would die at the snap of the fingers when in the OS. Strange. I charged the device while off until it said it was full. It came on at 95%. I followed the OP's guide until it turned on at 100.
Yet, it still started draining immediately.
The current culprit is "Mobile Network Standby," which is rich because this phone has no SIM, so why is it even bothering to try and futz with the mobile network? I had been keeping the device on Airplane Mode, but I'd forgotten to turn it back on. I just reactivated that mode, so we'll see if that helps.
However, if I watch a guitar repair video on YouTube (pretty staid, not like gaming or an action movie), the battery just nosedives again.
I don't think that rooting and flashing a new ROM is going to solve this issue.
I bought a replacement battery. I'm just not eager to try and install it. So I may just try root and flash, since it's easier. I guess we'll see what happens.

your battery is probably aged, I got the same problem and replacing battery is the only solution that'll work.

I reckon that you are correct. However, I am noticing that my phone hasn't crashed since I followed the OPs charging guide. That's something, at least.
Although monstrous battery drain is still a huge problem. I will be swapping the battery.
My question is: root first and flash something custom, just to see what happens? For evidence gathering ... in the name of empiricism.
Or just go ahead with the swap before doing anything else?

yeah try root and installing ABC oreo ROM if that doesn't make differ at all then replacing battery is the only solution.

My mi pad 4 turns off for no reason every 40-50 days with at least 30% battery .
Fast boot is not working. Last couple of times i tried holding & pressing random keys and eventually it came back to life.
This time i am not able to boot it up. Ive tried charging it for about 48h. Apparently its not charging either.
Does anyone have the same experience? What's wrong? What should i do about it?
Hi,
Like the mipad 1, i have the same problems with the 4..
Pressing power for 15 sec often work for me.
I recently bought one from aliexpress and i am faced with the same issue! D:
It turned on and i was able to set everything up but after about an hour the device dies (if left alone) or freezes if it happens while i'm using it and gets stuck is edl mode (computer recognizes it as a qualcomm device)
If the device freezes while i use it my pc can recognize it via ADB but says (offline) so i can not issue any commands.
the only way i'm able to get it to work is either let it sit for literally days, or let the battery drain to 0%.
I've tried re-flashing the original Chinese rom. No luck. same issue.
I've tried custom roms, issue still persists.
I'm currently messing around with it to see what it might be but i think that the retailer messed the device up when they installed their Global version on miui.
:/
I don't believe that it is the battery that is the issue because when i can get it back on w/o depleting the battery it is still at the same percentage.
Its a shame because it is a sexy device...well sexy paperweight.
I have the same issue and yes it is about 30% battery when it happens. To get it back to life I disconnect battery for a couple of seconds and it works fine for next month or two. Hope someone could find a cause of that and fix it.
I've changed battery and it seems to fix the problem. Last month before changing mipad started turning off few times a week. For now it seems ok,
First of all, sorry if this isn't the right place to post this thread.
Last night i was playing TFT on my Xiaomi Mi 10 as it shut itself down without any warning.
I'm sure i had more than 20% battery left.
This device is about 1 month old, and it crashed one time before, but i could just reboot it with the power button.
This time though, no reaction.
I tried every possible combination of Volume Up/Down and Power button presses, nothing. No vibration, nothing on the screen, just plain nothing.
It literally bricked itself. I did not root it or anything similar, I just used it normally.
Any ideas on what caused this, and more importantly how to fix this? I can't believe this.

I guess, that your battery is totally empty. Put on charger and leave on it few hours long.

I charged it 4 hours in the night and right now since 3 hours
Call service. Sorry. If it doesn't boot into fastboot (vol-&power) things are bad...
Try plugging in your phone to a computer. I had a similar thing happen to another phone a little while ago when out of the blue it just died. I tried charging it, wireless charging it, trying power buttons etc but it instantly fixed itself when I plugged in the phone to my computer via USB. Let us know how it went.

Try different cable or check if the cable you use is working. Then press both volume up, down, and power button for at least five minutes. It might reset the phone. It happened to me once time not on the mi 10 but my rog phone 2 and I press that 3 buttons combination and the phone booted up again. I know the mi 10 might not work the same way as the rog phone 2 but you have nothing to lose to try it.
Yeah I tried using another cable, although I know this cable works (old phone). I also tried charging it via my PC, I even tried to connect to it via ADB, it didn't show up in the device list after installing the drivers.
Pretty sure I'm going to give it to service, I still got warranty and I even have insurance for it.
Because of that I don't want to open it to get the battery out and back in, although I'd really really like to know what caused this. I literally played a game and zap it goes black never to be seen again... I hope the service finds the cause and tells me.
Anyway, thank you really much for the suggestions and the help. Incase I get to know what caused this I will write it here as long as I remember to. Until then Cheers Lads.
Same here. My step-daughter purchased this phone and received it Tuesday morning. Now it won;t respond to anything.
I was handed the phone with "pcsuite.mi.com" on the screen but upon connecting to my laptop the screen went black and now won't respond to anything at all. No Recovery mode, no fastboot mode, no vibrations, nothing.
From reading reports online from other users, it seems like Xiamoi really "dropped the ball"/"shat the bed" with this model

I've also performed "lsusb" to see if the device is alive and there's nothing there either
Hi,
Just few minutes ago my brand new phone just broke on me. I was holding it in my hand, locked screen, like minute later I tried to unlock it to no avail, screen just stayed black. There was a sound when I touched it by the fingerprint sensor, but no light up from behind the screen. I tried holding down power, then power+volume up, phone only vibrated, no reaction on the screen. I've connected it to the charger, and now it seems to be in bootloop - screen is turned off, and every few seconds phone vibrates. I've managed to somehow turn it back on once, phone booted to system, everytthing worked just fine, then I locked screen and it just stayed black, now I can't reproduce that, can't even turn it off, it's just vibrating every so often. Did it really brick in my hand? Software of Hardware? Everything worked just fine, maybe battery was draining a little bit too much for my taste, (15-20%/hour with screen on+lte/wifi) but 120Hz refresh rate+bright setting and AOD turned on 9am-9pm could do that. Do you guys have any suggestions, or I'm expecting trip to the service?
Sorry, but i cannot guess any reason. I am stumped as this bootlooping shouldn't beb happening... Very strange. May be its better to show it to service center guys.
Btw, i had tried this on my previous android phone to shut it down, like a hard shutdown. I had pressed power + volume down + volume up keys together to shut it down completely. Basically by pressing all the 3 keys. If you want to try, you can try it. I have not tried it on my GT, but had used it on Oneplue 2 and Honor View 10.
Hope your issue gets resolved asap...
Okay, I've contacted support via livechat, they told me it's definetly just software glitch, and to resolve this I have to wipe dialer cache (?) and all system settings - I did it, everything worked just fine, but today, again, same thing happened. First time phone just died in my hand, second time it was while listening to music via Pulsar, today I was just sharing wifi as a hotspot, phone randomly broke connection and would not unlock, but still I could tell it was on, because of vibrations and sounds. Not a software glitch after all? If I manage to unlock it I'll just recover it to factory settings, we'll see if that helps, but I don't like the sound of that.
What apps are -you- installing?
Launchers and power management apps are prime suspects...
Otherwise, mobo failure. It may be firmware but how far do you want to take it?
It should run fine out of the box.
Last time I played with launchers was with good old SGS about 5 years ago, only app out of ordinary was AccuBattery to check that SoT drain, but could it make such a damage without root privilages?
