Mi 9T Battery Drainage problem! - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hey people,
I have been looking around on XDA for quite some time now but this will be my first post. I have a mi 9T that I replaced the broken AMOLED screen with a normal LCD one. The problem is that after the screen started working again my phone's battery discharges incredibly fast even when it is idle. I have tried pretty much everything (including the solutions suggested in previous threads). First I thought it might be a battery problem, so I swapped the battery. No difference. Second I flashed different roms (EvolutionX and CherishOS) but nothing changes. I can't think of anything else to try, but if someone has any suggestions of how to troubleshoot this I would greatly appreciate it!

Install just ROM,for example lineage and don't restore apps. Check if apps are the problem or hardware

I am new to flashing etc so could you explain? You mean do what i did for my current rom but with LineageOS?

Install whatever you want, just don't restore apps. See if it's software related

Every install I have been doing is without restoring anything, just the Gapps that the ROM has. Not even connecting to the internet. Still the same

[Q] Huge lag spikes

So i've had my G2 for a few weeks now and it has started acting weird.
I have done nothing to it besides installing some apps, from the play store not from anywhere else.
But now it has started lagging MASIVELY, sometimes i can't even come past the lockscreen, and sometimes the lockscreen is not even there.
Also when i try to type a message or something it starts the massive lag, i have no diea why since i've jsut used it as it is, taking photos and using instagram/facebook/snapchat, no gaming or anything else.
Also, notifications comes after the real message i get, vibration comes on 15 seconds before.
It also heats up when it is in my pocket and drains the battery.
This usually happends when i open up facebook messenger, but i can't uninstall it since i find it necessary to have.
If anyone could i reply, i would be higly gratefull!
@RomWiz I dont know why all those things are happening to you but, you can try to wipe cache,dalvik-cache and flash dorimanx kernel and or switch to another stock based rom.
If you wanna stay stock I suggest to go to settings and see how much the apps are using your memory. Facebook is syncing the whole time so its really an battery drainer. On full stock I also cant suggest much what to do since I never had that phone.
I hope that someone else with real g2 experience could help you more with your issue, goodluck with your problem and I hope you can fix it soon.:good:

How could i wipe dalvik on the stock rom?
And i've had it for a few weeks, and i see no one else complaining about this lag on the G2, so i don't know why this is happening.
tried rebooting?
also check the battery stats in the settings see if it shows what's draining battery, that's most likely causing all the system hogging

I may also think that it has to do something with the thermal throttling of LG stock rom.
The only way to wipe it is in an custom recovery without wiping all your data.
I did a factory reset and it seems to be fixed now, but who knows.
Maby in a few weeks it'll start again.
@RomWiz alrigh have fun with your phone if it happens again I suggest to maybe flash an modified stock rom or the g3 rom port with dorimanx kernel.

[Q] A very strange issue with my battery

Hi.
I have been having very strange issues with my battery, and I hope that there are some people here who know about the hardware more than I do and might be able to help me.
First of all, the battery indicator is unstable, it can show me 49% of battery and suddenly tell me there is only 10% left. I am attaching a screenshot of my battery stats where those spikes are visible.
Or worse, the battery indicator might suddenly jump to 0% and make the phone turn off, then when I turn it on it shows that it has at least 25% left.
Second problem, I very often can't charge the phone. I connect the charger, and the notification LED doesn't light yellow, instead, the whole battery menu just disappears from the settings so I can't access it... And after a few hours it might begin actually charging, then the menu is visible.
Battery temp always shows -30 degrees celsius, or some similarly impossible temperature.
After trying to switch to a different kernel (from unleashed to hells core) and to a different rom (from purity to android L and liquidsmooth) I decided this is an hardware problem and bought a new (hopefully original) battery on ebay.
I installed the new battery. Now it does work a little bit better, but still, the problems persist.
Is there anything I can do, before buying a new phone?
It doesn't have warranty anymore, it's one and a half years old.
Thanks
Definitely battery failure. Replace the battery or buy a new phone

This is most definitely due to a faulty battery, so time to get a new phone. At least Shamu's release is right around the corner.
Hi
Thanks for your help.
I did replace the battery a few days ago, and the problem still persists. Which makes me think it's something else.

I'd try comletly stock rom, and see if the issue persists.
Yup, stock ROM always first step, then replace battery. If it still persists, than it is most likely some other hardware issue that might not be worth it to replace.

Exactly same situation with my Nexus 4. Battery being replaced and it's not better. Just ordered a Moto X 2014 and waiting for it.
I tried the stock ROM. And it didn't solve the problem. Is there anything else I can check about the hardware before replacing the whole phone?

Have you just flashed a stock rom, or completley restored the phone to factory settings using google factory images?

Hmm unfortunately this leaves me without any ideas. May ask how old is your phone and did you drop it previously?
It's one and a half years old, and well, I did drop it a lot.However, I always used a good case (ringke fusion) and I don't recall any recent drops prior to the time the problems started.

Discussion Thread : Cm12 unofficial rom by Grarak

Hi buddies
As Grarak chose to close the thread of his rom and that maybe some of you want to have some more return and exchanges about the way the rom works, discuss about bugs etc, i open this thread, so that we will be able to do what a forum is done for : talk and exchange together.
New version is 12082014, any return?
Testing soon..

i 've had terrible battery life, and searching on google lead me to a battery misc processus eating battery, problem solved with 5.0.1 by google
do you guys have the same experience, and have heard about a fix incorporation in the new builds? :good:
I had to go all the way back to the 11-20-14 build. I tried updating to the new builds 12-8, 12-9 and 12-10. No data at all on any of these builds.
Flashed the newest build! We're on Lollipop 5.0.1 now This update is supposed to help battery life. We'll see.
The new music app automaticaly force closes, and the DSPmanager was replaced with AudioFX.
thank you guys for these feedbacks.
Foxy, when you say the new music app, you mean the cyanogenmod one? strange, what could have change ?
Audio playback is fixed now ?

I don't know? It's just called "Music" but the icon is like a poorly designed not lollipop looking purple circle. But Apollo is gone so I suppose that's it. And audio playback works, just the app crashes right when I open it.

mhm then i think a change that has broke the app. I m sure Grarak will correct it in the next release
Ok, the ROM was going great for me, then yesterday at work my phone turned off when it was in my pocket. I tried turning it on, it booted, started doing the boot animation and then did that for five minutes before it shut off again. This time it wouldn't turn back on no matter how many times i tried power cycling or booting into bootloader. When I got home I tried charging it and the light wouldn't even come on. So I plugged it into my PC and the phone showed up as qhsusb_bulk. After researching that i found it means the bootloader got wiped somehow. My question is, how could my bootloader be gone, because as far as I know, no one has gotten their device S-OFF.
your device is bricked
seems there is a solution on the web but not working for everybody and for specific devices
i dont know what to advice you...
i dont know if it is rom related, but if it is, i wont flash this !
Yes that's what i figured. Luckily Amazon was nice enough to give me a new phone once I send that one in. I was just trying to figure out how it would even be possible that my bootloader got fried, considering my device was still S-ON.
any one who tried this rom found any bugs ???????? i want to know the bugs and want to know in htc 816 daul the second sim worked or not

I'm on a single sim Virgin Mobile variant here. There are bugs, yes. This is basically an alpha going into beta of lollipop. There is no one else developing anything new for this device so this is our best bet yet. Aside for some minor niggles here and there, this ROM is very workable as a daily driver. I would recommend a backup, and try this one out. I like it a lot. Grarak is quite amazing actually, many thanks owed.

Didn't test it. Haven't spent enough time on Lollipop because of the no data issue.
I've been playing around with the lastest builds, and I'm actually getting LTE to work without modifying anything, I just have to let it sit for a WHILE and it connects and works quite well.
HOWEVER, I have been getting a corrupt data partition issue with some non-google play apks. I assume that since the build are already not stable, adding homemade, root apks that modify data might cause some corruption. I'll keep playing with it and report back any further updates on how this may be happening.

Yah data works...just not good. It has to do with not being able to access APN's.
No one want's to sit "for a WHILE" to open a webpage or read an email.
On the latest build, System UI crashes.

leeco pro 3 x727 shuts down after few minutes

This happens only when I install any custom rom...the phone works fine with x720 5.8.018s version...anything apart from that device will shut down every 2-3 minutes ...very strange behaviour ...any one has any idea ?
any custom rom , android 6 or 7 , AOSP or stock based, it will boot fine and after initial setup , it will work for 3-4 minutes and then suddenly device shuts down. .. when i boot it up again , same thing happens, in one minute shuts down.
if i flash 5.8.018s stock rom , everything works fine....and it doesnt shut down...
After device bugs, my phone finally was restored into x720 stock ROM (i have x720). On boot it worked below 1 minute and reboots. I had to do clean data. Also booting x720 ROM into x727 is not too good idea. Maybe you should try to do more wipes?

I did all the wipes i could , cleaned all kinds of data... it was US version 5.8.018s originally and i tried to flash Omni ROm first , and other ROMS , all had same issues, so i thought going back to the stock US rom , but since US version of 018s is not available anywhere, i went to chinese version , and it works perfectly , no reboot/shutdown...... I have used number of phones and installed 100s of ROMS , i have never faced soemthing like this...i hve even used leeco pro 3 before, with all custom roms and no problems.

Ok update...i downloaded x720 021S and 023S and updated using in build update option..(local update) , and it worked, 23S is working without any shut down...so i guess, it is problem only with roms flashed thru TWRP

Usefull information, thank you very much.
Nearly the same problem here: My X720 is only rebooting sometimes, but more often switching off directly (vibrates one time and switches off). While the phone is in that status, the battery is discharging. I can only reboot the phone by holding the power button for about 10sec or to TWRP. Two times I was rebooting the phone and some (not all) settings were restored to default - reflashed the rom... Another time rebooting the phone it hangs in the booting display, did not get it booted completely again - reflashed the rom.... Very strange behaviour and don't know why this happens.
But for about the last month, the phone is only switching off and I can reboot and use it for an unspecific time.
That all happens with several ROMs - currently I'm on ResurrectionRemix 5.8.5. This is the most stable custom rom I have tested, but anyways the phone switches off in irregular periods. Sometimes the phone is about a day alive, sometimes only a few hours, sometimes below an hour. When I'm playing HQ games I think the phones switches off much faster, but not sure.
I'm also not sure - I do not have used the stock rom really long after I get this phone (was CN 5.8.018s I think) - but my feeling is, that the phone was definetely more stable with the stock rom.
Now after finding this thread, I will give the stock rom another try. Would you be so kind as to describe the process of going to the stock 023S a bit more in detail? First flashing the 5.9.021S for the x720 ROM throught TWRP and after that using the build in update option (rename file to update.zip into root folder)?
Thanks!

You do not flash a 21s update twrp that may brick you.
You have to go stock and flash with stock recovery.

Does anyone completely solved the shutting down issue on x720? I remember the same issue with the stock rom when i was getting the phone (5.8.018). but this rom could have been a shop rom, cant remember.
For me it seems that the issue happens more often whenever the phone uses more performance. Playing HQ games let the phone shut down after about 1-3min. doing nothing on the phone, it remains for about a day. Weird behaviour... will try to flash the stock recovery via fastboot and then a stock rom (no shop rom). hopefully it will improve the behaviour or even better solving the issue.
Sounds like a hardware issue. As for me, I have a couple of screen issues--I usually have my LeEco Pro3 Elite connected to a charger, and I sometimes don't use it for long stretches of time (say, 8 hours) because I have another phone as well. Once in a while, during those times the screen refuses to turn on. Sometimes the fingerprint scanner wakes it up, other times I have to straight up reboot the phone using the power button (I have to keep it pressed for two whole minutes for it to wake up the phone). Pretty annoying, dunno why it's happening. Could be a loose screen cable.
Now, if your phone is shutting down every few minutes no matter what, it could be a battery issue. I say this because I had a similar issue with an old iPod Color from 2005. The iPod would shut off every few minutes even when plugged into a charger. I changed the battery and it stopped shutting down.
Hopefully it's not a motherboard issue because replacing a phone's motherboard is never easy.

I don't think gameplay should affect the phone negatively at all. Especially a phone with a Snapdragon 821, a 14nm processor with efficient cores, for crying out loud. I play Fate Grand Order, a pretty intense 2D online game with 1080p graphics for 5 hours straight on my LeEco Pro3 Elite (Snapdragon 820) without it heating up at all.
Again, seems like a hardware issue because no phone with a Snapdragon 821 or 820 should be doing that. Especially while gaming.

Thanks for the information.
Could be possible... If I'm shaking the phone like a cocktail-mixer, it feels something loose inside it and this could be the battery of course which could be not fixed correctly. But I am sure, that this issue has also something to do what is happening on the phone currently. Sometimes I am going to bed and the phone does not move for 8hrs, it simply lays on the table. In the morning, it is shutted down. Need to hold the power button for about 10sec to restart the phone (usually hold 2sec to power on). Sometimes (not really often) it warm-starts automatically.
I think this could be also a memory issue or internal storage. Yesterday I was playing a game (Bowling by Jason Belmonte) and after 3min, the phone hung up, display remains on, no reaction on pressing the hardware buttons, waiting 5min... nothing happens. So I pressed the power button 10sec, phone seems to reboot normally, but it take a bit more time in my oppinion. Now after entering the pin, some phone configurations were resetted to default, but not all. Playing this came, it sometimes happened, that the phone switches off (with one vibration). Rebooting with a 10sec press and it runs again normally. This time phone hung up and some configurations were resetted to default. WTF?
Today I have played Hmmsim 2. Phone hung up again, pressing the power button 10sec, phone begins to reboot, but rebooting never finished (waiting for about 1-2hrs). Long Press power button (10sec) to try to reboot again - same behaviour, never ending ROM loading screen. Wiped to factory via TWRP and the phone reboots again, but all configurations lost, like freshly installed rom. OK, whatever, using the google backup for apps and so on... when installing the apps in the background, the phone reboots about 3-4 times, app installations not finished. Cancelled and shutting the phone down to TWRP, where I am now...
What I will try to say is, that whenever the storage or memory is used to much or something like that, the phone begins with that behaviour.
And now I am thining about what to try next. I think I will try to flash the stock recovery via TOOL ALL IN ONE then flashing a stock rom like 5.9.023S.
I am still not sure of a hardware issue...

The easiest way to tell is if the issues were occurring before you flashed TWRP. Were they? This is why you always wait a couple of months before modding your device. Otherwise you'll be stuck in a loop of doubts. By this I mean you'll be convinced that the issue has to do with your custom ROM or kernel rather than your device's hardware, but you have no way of knowing for sure because you never used the phone enough on stock firmware.
I was like you... my unmodified Zenfone 3 had a screen flicker issue and a headphone jack issue that I was convinced was a Nougat problem. I upgraded from Marshmallow to Nougat immediately after getting the phone. After a lot of research and posting threads on the Zenfone forums, I realized I had a hardware issue on my hands. The screen had to be replaced for the flickering to stop, and the headphone jack had been gimped to 0.3v by ASUS for some reason. I quickly sold the phone and got my LeEco.
Here's a thread I made on XDA about my screen flickering issue. It's a hardware issue: https://forum.xda-developers.com/zenfone-3/help/ze552kl-screen-flickering-lowest-t3660643
I've learned some important things from that experience: it's easy for your brain to trick you into thinking you've got an easy-to-solve software issue on your hands, when in reality you've got a hardware issue. You need to start making arrangements for a replacement device and get video evidence of your problems to show to the seller ASAP. Because that behaviour isn't normal. Now I hope you do have a software issue on your hands that the stock firmware will solve, but who knows. Be prepared for anything.

Thank you very much!
I am sure that the phone was doing the same on stock rom, but maybe fewer times. I have flashed a stock based rom now (Turbos mini 5.9.023s) and the issue still exists, but now the phone reboots normally more often than going into edl mode (emergency mode). I have found an old thread here on XDA and the issues described there sounds nearly the same. Finally the user in this thread also had hardware issue.
I believe also in a hardware issue, but I am still not sure. If I am looking to other threads regarding similar problems, there is always some regularity in the behaviour or the reported issues. In my case these rebootings (usual reboot or reboot to EDL mode) are definetely very unregular. On the TURBO Rom, these reboots happen definetely more often when the display is off and the phone sleeps. On the TURBO Rom, playing games seems to be helping lasting the phone a bit longer, the completely differnce to ResurrectionRemix Rom, where the phone was lasting longer when doing preferabely nothing. The issues are so inconsistant and this is making it hard to believe, that this is a hardware issue. Why the hell is the phone behaving different on every ROM - if it's a hardware issue, the occurred problems should have some regularity.
As I didn't have an OTA update option on the stock rom, I'd found out that this could be a "shop rom" (5.8.018), which is not the best choice nor for the first month(s).
I'm from Germany and I do not really want to return the phone to china or east asia for repairing (bought at banggood). This could take a very very long time. Changing to a new one could be also difficult because there are hardly any more devices out on the market and I need to return it for the change too.
But I am slowly at my wit's end and before these issues are making me more and more crazy, I will accept a problem with the hardware.

If your issues were occurring from the moment you got the phone, you know it's a hardware problem. Your seller sent you a defective phone and you should at least try fighting for a partial refund. If you paid through PayPal, open a dispute. If you paid with a credit card, ask for a chargeback. Now, the shop you bought it from might ban you for initiating a chargeback, but it's probably worth it. Or you could just cut your losses and move on. Maybe donate your phone to a dev who wants to try something crazy. :good:

Oh snap, it's a Banggood phone? I bought my x722 from Banggood. No glaring issues other than the screen one so far, but this does worry me for the future. How long have you had it?
This is the problem with Chinaphones. They're cheap, they've got good specs, but you can't guarantee quality. Especially with now close-to-defunct brands like LeEco. If you're still okay with Chinaphones, get a Xiaomi next. Probably the most reliable Chinaphone brand out there, next to Huawei. And try to buy from an official source. I heard The Solution Shop in Europe sells Xiaomi phones for cheap (?). And always remember to record your unboxings and document all issues from now on.

Admittedly I'm not sure at all if this issue was already present after starting the phone for the first time. One of the first things I have done during the initial setup wizard was using the integrated data transfer app by LeEco (scanning a QR code with the old Xperia Z, downloading app to transfer data to the x720). This app establishes a Wifi direct connection between both phones to transfer the data like apps and other stuff. This transfer process takes at least 6-7 hours and during that process I am sure that the phone was not rebooting a single time. Maybe a specific app or background process of an app causes this irregular rebootings. I have not testet this. I have installed the most common of my apps also using different custom ROMs later.
On the current ROM (Turbos mini 5.19.023s) I have now looked into the last_kmsg.log file severel times after the phone was hard-rebooting (not to emergency mode - the phone is switching down to emergence mode really rarely since I have flashed the stock based ROM) to debug for a kernel problem and the power off reason seems to be ""Triggered from PS_HOLD (PS_HOLD/MSM controlled shutdown)". In the log file I could also find some "kernel panic" entries. So I have a little gleam of hope that the issue is not a hardware problem. I have to test a bit more with the stock recovery/ROMto gain a better knowledge of the issue. I think I will post this into the ROM topic to ask a developer.

Finally - I got it working without any problems now!
Happily it seems to be not a hardware issue. I have flashed the Grossoshop ROM and Recovery via a provided .bat file. This .bat file has flashed the recovery first via fastboot, then the ROM via fastboot. This Grossoshop ROM was based on 5.8.018s I think. Then I have updated TWRP Recovery to the latest version via TWRP itself (flashed the new image). Then I have flashed Mauro's 2.2 (which is based on 5.9.023s) and it is running great! Super performance, no extrem battery drain, no reboots, all is working (except the chinese design downloads as I cannot create a Leeco account from Germany). But now I'm satisfied. :good::laugh:

Usefull information, thank you very much.
Nearly the same problem here: My X720 is only rebooting sometimes, but more often switching off directly (vibrates one time and switches off). While the phone is in that status, the battery is discharging. I can only reboot the phone by holding the power button for about 10sec or to TWRP. Two times I was rebooting the phone and some (not all) settings were restored to default - reflashed the rom... Another time rebooting the phone it hangs in the booting display, did not get it booted completely again - reflashed the rom.... Very strange behaviour and don't know why this happens.
But for about the last month, the phone is only switching off and I can reboot and use it for an unspecific time.
Thanks!

My x720 has done the same to me a couple of times now, Vibrates once and turns off and I have to hold the power button for a few seconds longer to turn it back on again which is odd.
The battery was charged over 50% % 70% at the times it happened and I wasn't even using the phone, It was just sat on the table in front of me.
I didn't have any problems at all until a few days ago when it first shut down.
I'm using Oreo - AICP 13.1 from here - https://forum.xda-developers.com/le-pro3/development/rom-aicp-13-0-pro3-aka-zl1-x727-x720-t3698058
The problem now is I don't know where to start troubleshooting When I get time I am planning on a clean wipe and fresh install of AICP again to see if that solves the problem
When using this ROM does your phone heat up a lot.

Help me solve my Idle battery drain - and better battery stats report posted

Hello,
Been struggling a lot with my battery drain since I bought my 6t.
I am unrooted and now with 9.0.7, I already uninstalled a lot of apps to try and locate the root cause for my battery drain. I never had social apps which I know can misbehave a lot.
I have location, nfc, etc always turned off, battery optimisation settings always on.
I installed better battery settings and what you see is during my sleep, and the phone drained a lot once more.
Another issue I am having is that each time the phone reboots the find my device is activated even after I set it to not do anything.
I need help though, I quite do not understand what I should do now.
What is my problem? What can I do to achieve the crazy screen on time some of you have? More, I would be happy to just solve the screen off battery drain. One day I had over 40% drain without using the phone more than 5 minutes.
Can someone please help me out?

The problem is that you messed up your stock Rom in the process of unrooting. My best advice is to root your phone again and back up everything with Titanium Backup. After that, use MSM download to return to stock ( The same software state you had it in when you first bought it). I can assure you that the hardware is fine, but misbehaving software will only cause more harm to your phone. No one will provide you with a simple fix like a flashable zip and dont panic because its not that big of a deal. I bricked my 6t right after misreading instructions, but it recovered and its heavily modded. Go back to stock and start over

I came up with that answer without checking those screenshots, but now its obvious. By unrooted, do you mean you had root and then unrooted or havent attempted anything? The other thing is obvious, your battery is draining because of google play services. I had the same problem, but i removed my gapps because i use better app alternatives that dont require google play services. The other thing is i use services though my browser than having a separate app for everything. I find it safer and i use Brave browser.

You probably got it right, I already had twrp installed but since it was not working I went back to stock. How did you figure that out?
I might need some help to do as you said since I do not want to brick the phone. What if i do a factory reset? Will it cure the problem?

A factory reset wont really fix the issue, but you could always give it a try if you backup your precious files first. The problem that i am currently facing on my device is that i cant port Google Camera. I realized that it doesnt work without google play services, but i am not going to start over from stock just to get one app (Doing so fixes everything, but there is a workaround). I am planning on Deodexing my stock ROM and installing MicroG. Its really difficult to find easy instructions , but i gotta challenge myself. Anyways, in your case you just need to give the MSM Download Tool a try, its normally used to unbrick devices and return them to stock. You can always use it in case you mess up your software to the point where flashable zips only cause more issues.
# 1 Backup
# 2 Factory Reset or MSM Downloadtool ( Your Choice!) The tool is on the Op6t Forum somewhere.

Accessed stock recovery, made a factory reset from there by erasing everything. In about 11 hours the phone used almost 20% battery and no screen on time! Just standing there the whole time. I think I really need to do something, will try that tool you pointed.
No chance of bricking right?
Regards
tried it, it gives me a sahara communication failed. not sure what should I do now.
EDIT: I remember better now. when I got the phone it was on 9.0.4, I updated to 9.0.5. Then I side loaded the temporary and somewhat "compatible" TWRP which I used to flash Magisk. not sure why but root checker said I was not rooted and since an official TWRPO seemed to be far I decided to lock the bootloader (this gave me the official recovery back).
Do you think this is what is causing me the battery drain? everything is working properly to the exception of battery drain.
ANOTHER EDIT: decided to contact oneplus directly and explained the situation (even mentioned I had twrp and that I flashed magisk. they asked me to send the phone so they will see if this is hardware problem or software. not sure if they are going to charge me or not but I think it is unfair to charge (lets wait and see).
Can anyone help me figure out how to solve this problem assuming this is a software issue? I would pretty much like to avoid shipping the phone, never had good experiences with these rma assistance in the past.
Hi Cesar,
Hentai already suggested you how your problem could be solved

The mistake you are committing is this: having installed BBS, you should have taken an idle dump (as described in the OP of the BBS thread) and posted it in the BBS thread asking for help. Screenshots won't help.
Google Play Services by itself rarely drains battery on Oreo and especially Pie. All the apps go through Play Services for their requirements and if there is a misbehaving app, instead of finding it, people blame Play Services (I am not a fanboy of Google).
EDIT: Having said that, I just checked your screenshots. BBS is not functioning properly and the readings are skewed. Which version are you running? From your battery history screenshots, I see that you seem to have about 2% per hour drain. At best it can be brought down to 0.5%. Uninstall BBS, reboot and reinstall it. Let us see whether this time it runs properly.

Nicee!! What firmware version?
I noticed that every time i disconnect the cable when phone is fully charged after few minutes the percentage drops to 98 and few minutes late to 95 and then is more more longer time to drop to 94 and become Solid the discharge.. Someone know what i can do for fix this issue
I am still in 9.0.7.
I think that drain right after disconnection from the charger also happened to me but not sure how it is now after my "cleaning" ! Before when it was draining a lot I had it for sure but the phone was always sucking battery.
