Hey guys! I want some advice to check if this problem is normal or maybe its a manufacturer defect.
Anyway, I bought this phone about 5 days ago, and in the time I've been using it, my battery lasts about 7 or 6 hours (also it takes like 5 hours to fully charge it, which makes it worse). I thought it was because the stock ROM isn't very optimized, but later I started using cm 12.1 and it seems to last almost the same. Also, I started using an app called "current widget" that checks continuosly some info like the mA that is using at the moment, and I found that when I use it, it's mA is between 500 and 600, and sometimes it's like 180. Is this normal?
I'm worried because I've read in reviews that the battery of this phone lasts about a day and half and mine barely lasts 7 hours. Please, help...
Mine will last for 2-3 days if left alone. I'd download an app or CPU monitor to see what's running and draining the battery.
I repaired it already ^^ I just flashed official firmware again and no more battery draining and heating.
Battery draining could be many things but usually comes down to rogue processes.
Since android is java based over C, it becomes a garbage collector. Be sure to clean your device frequently to avoid internal confusion.
If a simple cleanup doesn't work, you can try to remove processes from loading at boot.
I honestly think that a reflash of your ROM is a bit extreme for a battery draining problem. I would try to exhaust every other avenue first.
I know, but I even tried disabling apps and it stayed like that. Also I flashed other roms and the problem didn't stop. I was going to claim my warranty and that's why I flashed everything again and somehow that solved it. I suppose my carrier modified the software somehow and that's why my phone had that problem.
Put your phone in airplane mode when you aren't using it. See if the battery drain persists. How is your signal? If your phone has a low signal, it will actually boost its radiation to try and keep the signal or establish a stronger one. This only is a battery killer and an issue that cannot be fixed by any software/firmware update that I've ever heard of.
If what I suggest seems to be true, airplane mode will be your friend. Or at least turn off data while not using it.
Good luck!
I've had my Redmi Note 2 since August or September of last year. When I initially received it through GearBest, battery life was horrendous and the phone was hot all the time. I frantically searched for how to install custom ROMs, and after many hours of hopping around sites, I figured it out and fixed the issue. Battery life was quite good from then on out, and I rarely finished a day with less than 70% battery and an hour or two of SOT. I still got the impression that my battery life wasn't as good as the people who were getting 4+ hours of SOT, but I couldn't really complain since I'm not a super heavy user. Changing from MIUI to AOSP and CM based ROMs didn't seem to have a big impact.
Fast forward to January and I suddenly started ending days with 50% battery with minimal usage while on one of the first CM ROMs made by Bule. It seemed to happen all at once. This was around the same time as I got my Mi Band 1s, but after installing Gsam battery, trying different ROMs, and going a few days without the MiFit app installed, I determined that it wasn't anything related to having the new device connected to the phone. Nothing seemed to suggest that any apps I had installed were sucking more battery than they used to.
Then, about a month ago, my battery life took another dip and I found myself finishing days with 20-40% battery left with only an hour of SOT. I'm often at 60-70% as I leave my university in the early afternoon, and I hardly use my device at all during class.
Currently, I seem to lose about 1% of battery per minute of SOT. Standby isn't too bad, but definitely not as good as it used to be. Having problems across the board suggests to me that my battery may be faulty and dying slowly. I purchased a new battery, but it hasn't arrived yet.
If the new battery is clearly better than the original, then the problem will be solved. But if it seems to be about the same, then it's possible that it isn't the battery's fault after all and I'm doing something stupid to drain my battery. Update: New battery does not seem to be helping.
Does anyone have any suggestions? I've tried to use the Redmi Note Tool app (making sure to use the setting for CM), but I've seen absolutely zero change in battery life. I've changed ROMs at least twice since the problems arose to no avail. WiFi and Bluetooth are on all of the time, but articles I've read seem to suggest that these things are rarely to blame for poor battery life. GPS is used occasionally but isn't on consistently. Screen brightness is set to Auto with the bar below half.
Update: For those who have helped and those who may have similar issues, I believe I've found the solution. After completely re-installing the original China ROM with Fastboot and the MiFlash tool, the issue seems to be solved. I really have no idea what the issue was, but it was clearly something pretty fundamental that wasn't getting reset with TWRP wipes and ROM swaps.
Just in case someone wants it, here are the guides I followed:
ROM: http://en.miui.com/a-234.html
TWRP: https://felixsenada.wordpress.com/2...ng-twrp-recovery-and-root-redmi-note-23prime/
If you have twrp I suggest you to take a backup of the current rom and try messing around.
1. Try 3C Toolbox Pro or any free app tha allows you to change the permissions/freeze etc running apps. Change the apps tha start with the device. Freeze some unnesessary just for the sake of testing.
2. How many apps are you using? Not the ones you have installed and sittings, but actually using everyday. Did you install any in the same period you noticed things go sideways? 1% per minute is not a good sign.
3. Install wakelock detector and monitor what is draining your battery over time.
4. Clear cache/davlik through twrp and wait the phone to recreate the files. Maybe thats just it.

Thank you for your response.
I will look into 1 and 3. As far as apps go, I have a total of 51 apps installed (in the drawer including all the pre-loaded apps), but I only use an absolute maximum of about 12 of them, and on an average day, I only use a handful of those. The only things I can remember installing around the same time I first started having issues were Google Fit and Mi Fit. However, neither showed up in Gsam as suspects, and after changing ROMs on at least one occasion, I didn't reinstall them just to make sure. I still had the same issues with or without them.
4 is something I do regularly whenever I change ROMs, so I don't think that's the solution.
Just to make absolutely sure that I hadn't already overlooked something, this morning I turned off auto brightness and location. It's still too early to tell, but I think turning off auto brightness may have helped.
Nice. Lets see how this goes.
charge at 100 % with screen off flash latest china stable via fastboot(not recovery) use phone for 3 days like this(i now it's a pain but its worth trust me) .

Update: I've been traveling for the past two weeks or so, so I haven't been able to respond.
I flashed the latest Xiaomi.eu build before leaving on the trip, but this did not help noticeably, so I can pretty definitively say that it is not an issue with any of the ROMs I've been using. Although it was never really suspected, I suppose this also confirms that it doesn't have to do with my house/work being in a bad spot for cell/WiFi or something odd like that.
Having returned to find my new battery waiting, it seems the battery is not the issue as I have been getting the same behavior today as usual (only a bit over an hour into the day from 100% charge and I'm already below 90% with 8 minutes of SOT).
Unfortunately, I haven't tried any wakelock detectors or other monitors yet since I wouldn't have had time to figure it out while I was away. I can look into this now, but my instinct says that I probably won't find anything that GSam hasn't been reporting anyway.
Finally, I did manage to get 2 hours SOT out of it one day (with lots of GPS usage as well!) and about an hour and a half yesterday, so I know that it isn't incapable of heavier usage; it just seems that it drains more slowly at random on certain days. The only other thing I've noticed is that, when the battery is draining more slowly, the 'Kernel (Android OS)' seen in the GSam screenshot on the original post drops to being about on par with 'Android System'. I don't really know what this would indicate, but maybe someone else could propose an educated theory.

Thanks for the advice, but I have some clarifying questions to make sure I don't do anything stupid that could brick my phone (an excuse to buy a Mi 5 would be great and all, but I really ought to do my best to make this phone work since it can do everything I need just fine).
Can any ROM be flashed via fastboot, or is there a specific one I need to download? I downloaded the china ROM from here: http://en.miui.com/download-274.html#396
Which method of fastboot flashing should I use? When I originally installed TWRP to get the original ROM off of my device, I was confused and bounced around many different sites trying to get ADB and VCOM drivers working, but I see now that there is a simple MiPhone fastboot tool that seems like it would work fine: http://en.miui.com/thread-145555-1-1.html
Do I need to do any wiping first? Normally I wipe via TWRP, but will the fastboot flash automatically get rid of all the data? Will TWRP be wiped as well since you reference re-installing it later?
Thanks for your help!
http://en.miui.com/thread-283080-1-1.html
download fastboot rom here
extract it with 7zip , WinZip,Winrar (your choice)it's an archive basically since you have installed twrp that means fastboot drivers are already installed
now make sure u have twrp 3.0.2 by jemini since it's modded to not let stock rom overwrite twrp
so the recovery.img by jemini place it in images folder that you've extracted replacing stock mi recovery so you hit two birds with one stone .
than click the .bat file flash all
EVERYTHING must be erased EVEN INTERNAL MEMORY

Hii!
My LG G2 mini D620r is 2 and a half years old, and most of that time everything was ok. But, since two months ago, I noticed that the battery is draining much faster than usual. And also discharge wasn't happening continuously, but it had sam jums i.e. I would use phone for some ammount of time, and the battery gauge would show decrease in capacity of only a couple of percents, and then suddenly it would drop couple of percents more for no reason. Also I noticed that phone wouldn't charge up to the max. It would show that it is 100% full, but after only couple of minutes of idling it would drop to 97%.
After all that I thought that there was a problem with the battery and bought a new one. But it din's solve the problem at all. Problem just continued to apper so I came to conclusion that there was no problem with a battery.
I read somewhere that Android battery gauge can go crazy after certain ammount of time, and my phone in quite old.
So my question is:
Does anyone know what is the solution to the aforementioned problem?
Does this problem have anything with battery gauge?
And if it does, can it be solved by reflashing the stock ROM?
I forgot to mention that I'm using stock Android Lollipop 5.0.2, software version V20b-EUR-xx. Phone is rooted.

A few options you can try, cuz i had the same problem on my d620r:
- Calibrate your battery;
- Uninstall/rootuninstall bloatware by LG/google, and apps you don't need;
- Use Facebook Lite;
- Use Greenify and Amplify (ideally with xposed framework);
- You can try reflashing stock after full wipe, but i dont think it will fix your problems;
- Best solution > Flash a custom rom and do all the things above.
I didn't have that problem on stock, but on CM13. I was running xposed framework with lots of modules, V4A in the background and a custom kernel, but still, i don't think that was the drainage problem. I'm still using the battery that came with the phone, and flashing Resurrection Remix Nougat 7.1 by mobiusm, governor on ondemand and greenify almost doubled my battery life since cm13!

In september, I flashed CM 13 snapshot from august, and I noticed some bugs with it so I returned to stock Lollipop. I think that's when the problems started. Since then I have used Battery Calibration app (if you know some better apps of that kind please do recommend), installed Greenify, but not Amplify and removed some of the preinstalled LG/Google bloatware, but not all. I do not use Facebook app at all. After all that it came to my mind to do full phone wipe and maybe that would eliminate the problem.

I'd still recommend custom rom tho, preferably RR 7.1
And if you don't want a custom rom, make sure you are calibrating your battery correctly. By deleting the batterystats.bin file you dont really calibrate the battery, rather you reset the battery percentage meter. That is important of course, but before using the calibration app, make sure to do these steps:
Preparation: Hard reset the phone, root it again, install greenify (and amplify if you want), uninstall bloatware, charge to 100%. DON'T USE THE PHONE DURING THIS PROCESS FOR BEST RESULTS
1)Download Battery Waster and Battery Calibration from Play Store
2) Turn on battery waster (turn off flashlight option, it heats up the phone, turn on data, location and other battery consuming settings)
3)Drain battery to 0% until phone shuts down by itself.
4)When it shuts down, turn the phone back again for about 5 times
5)After those 5 or so times of turning on, put your phone on a charger without turning on (use wall charger if u can, and please use correct voltage of 5V)
6)When your phone shows full charge, unplug it and turn it on.
7)When you get to the homescreen, if you have less than 100% battery, plug in your charger again (without turning your phone off)
8)When it shows 100%, unplug your phone
9) Turn on battery waster
10) Let it turn off by itself
11) Do steps 4,5,6,7,8 again
12) Launch battery calibration app (root), and press calibrate
13) Restart phone
14) Greenify your apps and enable agressive doze in settings
NOTES: If on step 4 your phone sucessfully boots again without immediately shutting down, just continue draining your battery until it shuts down.
TIP: Keep between 40% and 80% battery
Hopefully your battery is like new again and free of its problems, but again flashing a custom rom other than fixing your battery, might even boost it, and custom kernels might boost it even more! (If configured right, that is).
IF YOU DECIDE TO FLASH A CUSTOM ROM, PLEASE DO THIS REGARDLESS
I hope I helped you!
Thank you very much @kasa ssg!
If this doesn't help, then there's no way to help me at all.
EDIT: Finally I found some time to do a recalibration of my phone's battery, and I think it worked. It definitely lasts longer now than before calibration. Also I returned to my phone's original battery that came with it first time it was bought.
So I bought this tablet a couple of months ago and was always amazed by its battery. I could leave the tablet on for days and days that the battery would hold without any problems.
Suddenly and out of nowhere, I started to notice battery drain while the tablet is idle. I would charge it at night and next morning I would have less 30%, something that never happened before. This with Wi-Fi off and pretty much everything else. I know there's always consumption but these numbers don't make any sense.
Recently 7.0 came out, I decided to give it a shot to see if it would fix it. Did nothing, tablet is exactly the same. After installing the new OS version, wiping data and cache, disabling all the unnecessary features I could think of.
Also tried to go back to stock 6.0.1 and the problem is still here. Since nothing helped right now im back to 7.0. I have no apps other than the stock ones and I'm running out of ideas here.
Mine too, on 7.1.2 Nougat custom ROM drain like hell even if the tablet it's shutting down, charged at 100 % in the evening and in the morning after boot remaining only 75 %.
Clean install with wipe and everything !
I don't know what's causing this behaviour !
Haven't been here in a while, sorry.
I tried everything and since nothing fixed it, I contacted the store and used the warranty, they sent me a new one. Apparently it's a known problem and they were very quick stating that it couldn't be fixed.
Maybe you should try the same, if you haven't already..
Hello all, it's been a while since I've posted but this is quite a serious issue and could some guidance. A few weeks ago, I finally updated my Galaxy S9+ to Android 10 after being on 8.0 for so long and it's been a decent update so far. I had gripes with SoT not being the greatest but it was tolerable. Last night, I received an update for my phone and I installed it. Didn't think too much of it and continued on. I charged from my phone to ~87% today, used it lightly while working. By the end of my shift, I had 50% left.
I left the house to go for a 81 minute walk with 47%. I usually don't worry about having enough juice to make it back home but I experienced the worst battery drain I've had with this device so far. During my 90 min walk I:
listened to Spotify using my Galaxy Buds (one ended up dying towards the end because I forgot to charge them)
Checked Instagram occasionally and responded to some texts
Took 2 pics in Snapchat
Had a short video call on Messenger
It was right after the video call I noticed my battery was at 17%, which I thought was very strange. I don't leave apps running in the background for long and I have a habit of closing them out when not actively using them and I noticed the battery kept on draining despite there being no apps open besides Spotify.
Turned on the medium power saving and within a few minutes, I was at 5%. Decided to kill everything and pit my device on max power saving mode for the first time since I've owned the device. By the time I was home, my phone was at 1%.
I'm really baffled at how the battery drained at an exponential rate. I'm a medium user and I've had this phone since late 2018. Never leave location services on, never used AOD, and used the FHD display instead of QHD along with dark mode.
I'm hoping today was just an outlier as I want to keep this phone for another 2 years, but if this happens on a consistent basis I'm gonna have to start searching for a new device.
In the meantime, I have charged my phone to a 100% and disconnected the phone and observed the following:
Within 2 minutes of disconnecting, battery went from 100 - 98%. Not a good sign considering it was just idling
The battery continue to drain every other minute and I could see the battery go down on each unlock
Wiped the cache partition and I went from 93 to 94% for a brief moment prior to the phone going back to the same pattern
This is very worrisome to me as I don't believe the phone will last until midnight, I'm wondering if it's possible to roll back to the previous update.
TL;DR - After the update yesterday, the battery drained at an exponential rate despite light to medium usage
Also, here's some screenshots of my battery usage

I know this isn't the answer you are looking for, but all I can do is suggest changing the battery and doing a full, stock firmware flash via Odin to completely wipe your phone.
I recently replaced my phone's battery and did flash the firmware and my battery is really hanging in there. My battery was also 2 years old and before, I would get about 3h SOT when I play a game (and I do a lot). Now, I'm getting 5h SOT no problem with about 2-3h gaming included, so I really do suggest a battery change. I'm thinking you could be able to squeeze another 1 or 2 years into this amazing phone.
