Hi all,
I've got my sg2 since june and since the first moment I have got the same problems. I had the stock ROM & kernel with android 2.3.3. The problems I experienced were these:
1) extreme low battery life (6-10 hours, with normal usage)
2) when using heavy apps, my s2 just suddenly turns of. When rebooting it, it has a battery drop of like ~15%. (this only occurs when battery is already bellow 40% left).
3) Like 5-20 times a day (it really difference day-to-day), I got the notification that I have to put my sg2 on a charger. - So the battery bar drops from example 80% to 1%. After like 1 or 2 minutes it just fills up back again to the 80% before. Sometimes when this occurs, it also turns in a few % (like 80% before, and afterwards 75%).
So what did I already tried to fix this?:
- bought new 1600mah battery > didnt solve the problem, conclusion: no hardware malfunction
- I thought the problems could be occured by the tiny space between the battery and the frame of the phone. So it had a lack in connection... So I filled up the little space with i tiny piece of paper> nope didnt helped.
- downloaded mutiply apps for battery saving, task killers, etc etc.> didnt help!
It's really really frustrating, and I'm guessing more and more it's just a software problem. I do have warranty/insurance on it, but i don't want to send my phone to a repairservice because then I've no phone for like 3 or 4 weeks.
So my last option for me was to try a custom ROM and Kernel. So last week I installed the Lite'ning ROM. I also followed up the advice to calibrate my battery, so i did.
And the first day it was running really smoothed! At the end of the day my battery was still alive and I've used it for over 20hours, so I was really statisfied... But a small sidenote: I had a really busy day at work, so I didnt use my phone that much.
So next day, used it alot more. After 5 hours it had only 50% left.... And that's not all, my phone turned off suddenly. Not once, not twice, but 5 times that day.
Seems all these solutions didnt help. The only positive thing of installing Lite'ning ROM is that i now have about 4 or 5 hours more battery life a day.. But if I use it alot, it shut downs a lot more. Wich lead in more battery drops after reboot.
I'm really desperate, and I really don't know what to do now. Does someone have got these really frustrating problems, and do you guys have got some solutions?
And one more question: is my warranty/issurance voided after installing the Lite'ning 6.1 ROM? or can it by tresspassed by using a Jig?
Tnx for your time, and I really really hope you guys can help me cause i'm really getting sick of all this. It's killing me!!!
ps. sorry for my bad english
your warranty is voided by installing custom rom but u can unroot and use the jig to remove counts in counter.
now apart from that it seems if u use your phone for 5-6 hours continuous it will drain the battery because main source of battery drain is the screen display but for moderate use it should be a little over a day.
i am unclear about your usage but still if you have doubts you should really get it checked at a service center.
I would flash back to stock, use the jig to clear the flash counter and exchange that phone, seems it has some type of hardware issue that could be related to temperature as it only shuts down when you use it.

My usage is definetly not THAT extreme, i guess moderate: I never watch movies or youtube, just some messages with WhatsApp, about 4 of 5 times a day checking Facebook, same for Twitter, always GPS off, some time of the day Wi-fi on, never play games, always closing apps on background.
i've got an example of my battery usage (this is one of the best battery usage days i got!!!):

Today step 2) happened to me
Hello all,
I bought the Atrix around 6 months ago and I have always had the same problem I'm about to describe. First I should mention that I used to have a stock rom and stock radio (77.15) until a couple of weeks ago when I flashed Cyanogenmod and radio 77.30p, yet the problem is present in both configurations.
My problem is as follows: my battery life is mediocre. Without using the phone very heavly, I get around 7-8 hours until it shuts off. Since day one I've tried many different fixes to see if the battery improved without success. Now here's the fishy part: for whatever reason, every time I make a full wipe (when I was using stock I did it from the "reset to factory defaults" option, now I do a full wipe on recovery) the battery lasts an insanely amount of time, something like 24 hours or more.
Here's how it usually works for me: I do the wipe, I boot my phone and configure my accounts, the phone syncs and installs the apps I usually use. Like I said, that day the battery will last forever, last time I've tried this I reached around 31 hours before I plugged the phone back on, and it was around 17% still. Now, the next day, without installing any new app or using the phone for nothing different, I go right back to the mediocre battery life. For example, it just went from full charge to 88% for just 10 minutes of browsing the net on wifi, not even using 3G.
Like I said, this happened with stock ROM and now with Cyanogenmod regardless of the radio I'm using. I have calibrated the battery a million times, I've tried with Watchdog which didn't show nothing, the same with Better Battery Stats. I really need some suggestions on what to try because it irritates me that the battery is dropping so much with such a light use.
Thanks!
I'm getting also quite short battery life with CM7. I'm wondering what the reason could be. It gets down with 15% for just 5 hours without any phone calls. I have just whatsapp and email checking every hour. No other resource hungry applications. With the stock ROM and the same usage I'm getting around three days ~ 72 hours.
Well in my case it's the same but with both stock and others roms. I suspect it's a software problem because I get normal battery life when I do a full wipe.
Did you try to revert back to unlocked bootloader.
What I found strange is that somehow the indicator doesn't show the ratio mAhercentage. On 85% battery the calibration battery shows charge 4030 mAh which is not 15% less than the full charge of 4200 mAh.
Well actually this problem has existed from before I unlocked the bootloader so I don't think that's the problem. And in my case the mah percentage is correct. It's like if somethings draining the battery that I can't find. Maybe is a problem with my carrier?
If the coverage is poor where you live then it is possible to get lower battery life than expected. Another solution is to revisit the application you use, try also to do a full wipe including formatting the internal memory card.
Go through this process: http://forum.xda-developers.com/showthread.php?t=1198333
You'll be good to go after that. Check also BetterBatteryStats here in xda, will show you what processes eat the battery.
Thanks but I've tried that when using the stock rom and it didn't help me. I think that solution is for a different problem as it's mainly to display the correct mah percentage, which is not exactly my problem. Also, CM7 already includes juggernaut fix.

Have you tried a different radio?
Yeah, like I said I had 77.15 at first and now I'm using 77.30
There's more radio's, check in General.
Ok, I flashed 77.36p and there was an improvement, I've unplugged the phone around 13 hours ago and I'm at 25%. Would you consider a good battery life for a light use? It's getting better but I saw many people crossing the 24 hour mark on their phones. Are there any other radio to try other than 77.15, .30 and .36 that would be worth it?
Do a full wipe in Fastboot & install Nottach's DarkSide and leave it with the stock kernel. I'm at 77% with 1hr 40 minutes screen time & 17,5 hrs standby..
P. S. I'm using the N_01.100.00R radio. Am in Germany, though on an at&t phone. Best radio so far.
Anywhere from 13-20 hours is fine but keep in mind it's all dependent on what's on your phone. If u have a bunch of apps pulling data from the internet or something ....I mean its all dependent on your phone setup.

Well, for now I'll stick with Cyanogenmod for a while because I really like it, but I have flashed the radio you've mentioned, we'll see how it behaves. Thanks!
Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.

Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

Hi guys, this is not an usual battery drain problem. I am more or less an advanced user of android but I´m writing here because I tried all my ideas and none of then worked.
I have 2 Neo V, stock. One day one of them started to have battery drain. Im talking about 6-7%/hour with no usage, the other one is around 1-2%. So with any use my phone don´t last more than 14h.
I started to check the usual(wifi policy, services running..), and don´t found anything, I switched the batteries between both to see if that was the problem but drain was still in the same phone.
I rooted the phone, tried BetterBatteryStats and CPUspy and all is OK, most of the time DeepSleeep etc.
After all I unlocked the bootloader with the S1tool testpoint etc and flashed some Cyanogen 9 rom + kernel, and the problem still persists.
I think there is nothing I can do and my phone is useless because I suppose I don't have warranty anymore.
Any ideas about what could be? Even if its hardware, what kind of hardware problem can make this high battery drain if the CPU is not working ?
Thx in advance
edit: In HTC we can also flash different RIL´s (radio interface layer) to improve signal db, avoid high battery consumes etc. There is something similar in NEO V? Because I didn´t find anything.
There are a couple things you can do:
1) Did you check that you had mobile signal all the time??, because losing mobile signal is THE biggest battery drain possible
2) Post some BetterBatteryStats screenshots so we can see what's happening under the hood
3) Try a different ROM/Kernel combination, that sometimes helps
And no, there's no RIL flashing here, just different ROMs/Kernel/Baseband combinations
I HAD the same problem
Even I faced a similar problem on my Neo V after getting FXP CM9. FXP 122 was fine. But FXP 123 and 124 drained the battery very badly(No considerable Deep Sleep in CM 9). So I switched to AOSP Polish blood. Battery life was excellent but it lacked customization, so I switched to AOKP v38+ AOSP kernel. Superb ROM but again not so good on battery (but better than CM 9). Yesterday I flashed the FXP 125 kernel. More than 5-6 hrs of WiFi, 15-20 calls and texting and some instagram and I still have 20%. I'm charging my phone now!!
I´ve uploaded some screens of bbs, cpuspy and batterydrain with wifi on and after switching it off.
Hope it reveals something, what really annoy me is the deep sleep activated most of the time, so I don´t really know what to search.
Just as I thought, what's happening to you is what happened to me a year ago and I thought changing phones would help.
Your problem is basically, bad signal, as you can see in screens 4,5 and 7,8 "No Data Connection" and "No or Unknown Signal" are preventing your phone from going into Deep Sleep, the problem comes from bad 3G signal (or just bad network signal if you don't have 3G) and that is known to basically eat up all your battery.
How is the network signal where you are???, because it looks like it's realllllyyyyy bad.

Are you sure? Take a better look.
Or at least deep sleep graph. And those graphs "No Data Connection" and "No or Unknown Signal", are also ok(ven though the name is confusing a bit), I have the same.
I'm not COMPLETELY sure but this is exactly what happened to me a year ago with a Samsung Galaxy Mini, also if you look at graphs 4 and 7 Deep Sleep doesn't have as much time as the data and signal bars, to me that seems like those two are keeping the phone in wakelock state more than it is spending on Deep Sleep.
I´ve been experiencing this problem for weeks. About signal I tried everything because:
- Phone worked perfect with SIM and all bars (I live in the downtown of a big city)
- When the problem started to happen I switched to another phone and this one was working without SIMcard so there was no signal at all.
- Some days ago I used another SIM which also have all bars.
I Don´t think there is a problem of the signal . Also in my other phone, and as you can see, Deep sleep is working fine.
I reread your first post and the only hardware problem that I could think of is a faulty battery, did you use to leave it charging all night??, because that tends to burn the battery and it does hold a lot less charge.
According to what I've read, everything seems to be fine software side, my only idea would be that you reflashed stock ROM and check if the problem persists, reflash but don't restore any data, the problem could be a misbehaving app.
I have 2 Neo V (my father´s and mine) I switched batteries, and the problem persist in the same telephone. Also both of them have less than 2 months, so batteries are new.
Also revised the voltage in the CPU and it is alright.
Well, the only thing left to check (IMHO) is a misbehaving app or service, maybe check for task killers or battery savers in the "broken" phone, those are known to eat up the battery like it's ice cream!!
I believe I have the same problem. I can't remeber when it started since I tried lots of roms,
but I flashed latest ICS from pccompanion with no other tweaks for some days and it
continued the same.
I also thought about bad signal, but at night in flight mode it also spent 40% of the battery.
With a good kernel, undervolting, 2G... I can get to 15% 20% at night.
I've also switched batteries with other neo's and no difference.
Phone is 5 months old.
Not sure if it might come from the rooting process. If I understand right, the 0% issue
that some were having was more of hardware issue (or I'm completely wrong?) Then maybe
there is also something related?

0% was a software related error (flashing GB 2.3.3 after having 2.3.4 broke the battery gauge firmware), however that problem doesn't exist on ICS, I find it reallt strange that both your phones have that problem, I've had my Neo for 8 months and the most battery I've lost overnight has been 10% (with CM9 and really bad signal).
Maybe the best thing you guys can do is send your phone to service.
I have a similar problem with my mt15:
when I buy my phone battery was ok. about two days with intensive social use, no gaming.
5 months later, battery drain begins: deep sleep and 8% per hour , airplane mode 8% per hour
tried almost every popular rom in development forum ICS stock, codename, tweaked, cm7.2, cm9, jjhybrid, KA, ...
tried every popular kernel: stock gb, stock ics, alliance, suave, super, nightelf, cm kernels...
battery drain happens while phone ON, happens with airplane mode, AND happens with PHONE TURNED OFF.
I thinked about battery fault. replaced my battery with a new genuine one. Same results.
If I remove the battery from phone, IT does not drain. 24h later battery is still 100%
So my neo has a hardware problem I think. And there are many people with same problem. look for "neo battery drain while off"
Neo is a buggy phone. you can be lucky, or not. but many people has these issues or 0%batt.
I give up!
After sony abandoned x10 mini pro (random reboots, eclair), I had given another chance to sony with neo. I like sony designs, but Im really tired.
sorry about my creepy english
Try freezing "Calendar" with Titanium Backup and see if battery lasts longer. It helped for me.

about battery drain when phone is off
its not consuming your battery while its off
when you are turning the phone on
cpu usage will be on 100% to run all necessary sevices and apps and most use goes to get signal
that's normal
i suppose its aroumd 3-5% of battery consume
im not gonna be at the same side with you
actually neo is a wonderful phone
i beated the score of sensation xe in antutu benchmark with it
just google it around the internet
there will be some fix mate..
Neo is not buggy at all maybe yours but not mine
this might work for you
i just found it
1-flash build 42 official rom on your device
2-root the rom (there are plenty of ways around internet)
3-flash this kernel via flashtool forum.xda-developers.com/attachment.php?attachmentid=780407&d=1321113977
4-now turn on the phone its gonna show 85% of battery
5-install this forum.xda-developers.com/attachment.php?attachmentid=897721&d=1329003275
6-plug the charger into your phone
7-from the menu of app select start full charge
its gonna take 3-3:30 to be full
may be you've seen it around web
i translated it from a persian forum
HIT THANKS IF I HELPED YOU
In my opinion, a phone broken by a software update/downgrade is buggy.
About battery draining while off, not all neo have this issue, but mine is not the only one.
On the other hand, about power consumption while booting, if i remove battery while off, wait some hours, and replace, after boot battery is 100%
Sent from my JJ's Hybrid MT15i
I had this problem too, even when the mobile was off, the battery was drained...
I sent my phone to after sales service and now it's normal drain 2 - 3% per hour when idle. (I was on stock rom and kernel, never changed).
There is maybe a bad hardware series
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) .
flash twrp via fastboot than flash xiaomi.eu 7.3.2.0 and super su .
4-5 hours SOT assured (assuming your battery doesnt have problems)

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.
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: 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!

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
