Hello everyone!
So I have been having these battery issues since April security patch. the phone gets really warm to the touch even by doing the simplest of things like browsing and watching youtube. Android OS keeps the phone awake 80% of the time and I am only getting 2-3 hours of use throughout the day. Restored the phone to factory settings(fresh start, nothing restored) three days ago and still the same issue. Android OS drains the battery life even though I made sure that only google apps are installed on the phone.
But today things got even weirder. I disabled Google Now and location services as a test and the battery drain and heat issues were gone temporarily. I was getting a great battery performance from morning to afternoon. I check my battery stats and I notice that Google services mysteriously drained 17% of my battery life and that it's been running for 21 days straight? That's impossible since I just did a fresh reset to the phone three days ago. I rebooted the phone and that "Google services" drain changed to WiFi instead?! That's crazy!
I contacted Google store support team and they have been really helpful so far. They offered to replace the phone with a refurbished unit, but I don't think I am ready to give up on this phone just yet.
Thank you!

I hate to recommend this, but sometimes things go out of wack after a SW update, so a hard reset would probably be needed. I would try that (just start from zero) before jumping into a refurbished phone that might have some other kind of issues. Have you tried a hard reset yet? I see that you did a fresh reset. Did you go through the recovery though? Not just the regular UI. I think it's better to clear cache, and every thing through the recovery (custom or stock).

I did it through recovery. I have cleared the cache and rebooted the phone several times the past few days. Nothing seems to help at all.
Turn off your google backup.

Wow. Maybe a custom ROM might help? Have you tried that? That's the last thing I would do. Good luck!
Not recommended but I just flashed January vendor and ROM and that has helped my battery life. I. Believe it is the security updates that kill our battery.

Is it a widespread issue? Like I said in my post, I saw the decline ever since I got the April security update. The May patch actually managed to make things worse. There seems to be something hidden in the OS that it's draining the battery and causing the awake issues. I haven't tried rooting the device because I lack the experience to do so. I will probably look into it on these forums, but at this point I have tried everything.
Disabling Google now helped a lot and it exposed some sort of a glitch with the stock battery monitoring app. I am not sure if it's hardware or software, but it's certainly not normal. I am tempted to just replace it, but I am afraid that this issue will just plague the new one from Google. I am really disappointed How Google handles updates on this device. I always thought that stock android is most stable version of android, but the software on my old Xperia Z is actually more stable than this. It never had battery drain issues and standby battery life was always great. The battery life on Nexus 6P is actually worse than the Xperia Z even though that phone is 3 years old.

I've seen a lot of posts over the months with people having the same problem we are. I came from a mid range LG stylo with a snapdragon 610. I would have 8 hours screen on time daily. Its sad that goggle cant get the same out of their own hardware. Also I have seen that the Note 5 and S7 Edge both get better battery life as opposed to our stock phones. For as much as people praise stock and look down on Touchwiz, they are doing something right over there.
But it doesn't affect everyone and that what puzzles me. Only certain phones are hit by these issues, while other people are getting excellent battery life. I have seen plenty of people post screenshots of 6 hours+ of on screen time. I am lucky to get 3 hours. I think Google should really invest in creating a better power management system into Android. Companies like Sony and Samsung built their own and the battery life on their devices always perform predictably relative to what I am seeing on this phone. I have never witnessed The doze feature kick in since I have bought this phone. Sony had stamina mode since 2013 and it actually worked.

Most of those people posting those outrageous number root and do kernel tweaks. I've gotten at most 6 hours SOT on stock without root. You are right our phones do all react differently to certain circumstances. I don't know if it's feasible to you ,but you should try rooting and trying out a few Roms some help others don't. If you aren't into Roms and decide to root try earlier vendors and stock roms and see it those work. I'm not an expert by any means just my suggestions.

Well, the fact that you are having great battery life proves my point. It's either that the quality control of the batteries used on these phones are terrible, or that the software or kernel are corrupted from factory causing these issues. There is no way to fix them by hard reseting the phone so far. I am going to try to flash a stock rom on this device and see what happens. Thanks by the way.
1) Are you rooted? If not, at least do that and install BBS in order to track down what's eating your battery.
2) Probably we'll run into a common problem / bug the last two months.
After unplugging the phone, it seems that the wakelock *backup* runs constantly, does not let phone get into sleep, and runs in the background while using your phone causin battery to drain faster.
3) About battery life. Comparing battery results between two users it has no point, unless you really now his usage pattern. Not only the setup, but which apps of them used most etc.
For example Facebook app is real battery eater. I've seen an hour more SOT without this app.
I can give several examples like this.

I used to get OK battery times on this phone, it easily lasted over 60 hours without really doing anything to it apart from disabling wifi + bluetooth.
Then i rooted it and using SetCPU i got 4 - 5 days battery, very good.
Now, for no reason at all, it suddenly lasts about 24 hours with very little usage, and nothing has been changed. I've tried uninstalling everything and using SetCPU + Juice Defender + Disabled Wifi and Bluetooth. No help. Screen brightness is on 60%, but like i say it dont get used much so that wont have much effect.
Whats going on? My sister also has this phone and her battery is a joke, lasts about 14 hours at most, sometimes not even her whole work hours, and ive tried everything to get it to last longer, even rooted it and put SetCPU on there, disabled everything, and uninstalled everything. Un-rooted or rooted phone makes no difference.
I know lots of others have battery problems too... something seems really wrong with these phones, i dont know if it's android 1.6 or the hardware. But i'm starting to think they are utter **** and should not have been released.
Any suggestions would be good, thanks...
More details please...

There are ways to find out whats consuming the battery on your phone. Settings-> About Phone-> Battery use, is one.
You can use the application called "Spare parts" to get more details on battery history.
By your own admission, you have seen the battery last upto 4-5 days, there could be many different things that may have happened between then and now. Trust me, 1.6 and the hardware are fine so you can tone it down a bit.
The forums have several threads on this topic so read them. Monitor your battery usage and try to isolate the problem.
At the worst, your battery could be the culprit... its not unheard of. If you can track it down to the battery, you can ask for a replacement if your phone is still under warranty.

It could be the battery, but what about my sisters phone? she already purchased a 2nd battery because the phone did not last the whole work day. So it's highly unlikely that we have 3 batteries between us that are defective.
The point is these issues should not exist in the first place, i shouldn't have to monitor the batterry for hours and spend hours messing around trying to get a battery to last longer. Everything has been uninstalled anyway so i can only see basic phone functions draining the battery like Cell Standby, Display, and Calls. Same with Spare Parts.
We're both in different area's too, and signal is good in both, so it's not like the phone is constantly searching for a signal either. Even our networks are different.
I've already read many other threads but nothing has really helped. Tried Helix Launcher and other interfaces too.
So i'm having to disagree and say it might be a problem with the hardware or Android on this specific hardware, which would make more sense, i mean something with software would more likely be the cause of this when it's been proven it can last longer. Just a quick google search will show how widespread this is, and the guy at my local phone store even brought this issue up without me even asking about it.
I'll keep trying though, and thanks for your help.
Just wanted to throw this out there and see if anyone happens to be getting a lot of partial wakelocks without screen on or if your overall battery life has decreased since installing the 4.1.1 OTA. When I first purchased the phone, I had very very few incidents under my battery info where I would have a session awake without the screen on. Post update, seems like I've got a ton of really small wakes with no screen activity. I have turned off Google Now and every GPS/Location setting I could find. Downloaded Better Battery Stats today so I'm going to see if I can get some better info on what's going on, new to the program though and I don't understand most of the info that it reads.
Prior to the update, letting my phone sit overnight I would maybe see a 3 or 4% drop over the course of say six or seven hours. Now I'm seeing a 3 to 4% drop in battery per hour, more if I'm actively using the phone. I'm going to do more testing, specifically overnight to see how it fairs. Just wanted to throw this out there and see if anyone else is experiencing any of these issues.

I am noticing the same thing. Don't know the cause. Keep sync off all day.

Im getting the fast dormancy symptom again... no matter what i tried I cant fix it... always connecting as HSPDA+ even if im not using......anyone got any ideas?
Hmm, might try a factory reset and not installing any apps at all and seeing how it fairs. By chance, do you guys have any of the stock bloatware apps disabled? Not rooted/Frozen, but just disabled via the apps menu? Wondering if perhaps disabling any of them might be a trigger.

Yea i'm getting that. I'm using 13% overnight now vs like 4% before. Not sure about the wakelocks though.
Some random things I've noticed are the blur widget resets itself alot. And the transition to the settings window on the left is laggy. How would one revert back to ICS? Google Now is not that worth it to me and the phone was smooth enough before. I'd take the battery life over the new features.
I did buy a second Razr M for my girlfriend that's still on ICS. I guess I can do a side by side compare this weekend.
I am loving the update.. only issue so far is fire fox crashing..no battery issues. Must be settings guys..

i don't think it is setting i have all my syncs to manual, and i have been noticing a lot worse battery life since the update i would have 18+ hours or so off charger with pretty heavy texting / game / some voice calls. Now i'm not getting close to that. I just disabled the fast dormancy service to see if that helps any, ill post back results
Just did a factory reset today, I'm not going to disable any of the bloatware this time, and I only installed BetterBatteryStats as well as updated all the default apps in the Play Store. Going to see if I get any wakelocks this time around.
Last night, after a period of 6 hours, I had over an hours worth of partial wakelocks from AlarmManager (subheading Phone).
-Matt :good:
I disabled Google Now and my phone used 7% battery over 6 and a half hours. A little bit better.
A factory reset (annoying as it is) helped me considerably. My phone was also seriously laggy before the reset...slow like my old DX on GB, much worse than factory ICS. It finally feels smooth now, like JB should.
Still seeing a lot more wakelocks than on ICS, but it doesn't seem to be draining the battery like it was before the reset. I also removed or disabled a couple of apps that seemed to be serious offenders (Accuweather was one).
Did a reset on mine as well and did not restore from Google backup. Still seeing wakelocks, but as someone noted earlier they don't seem to be draining the battery too much. With that said, the battery does still seem to tick down much faster than on ICS. One thing I did find that helped, although honestly it's not really a solution, is turning off data use when I'm out and about just answering texts and such. If I have data/wifi disabled, I'm getting closer to the battery life that ICS was giving, but then again who wants to go around having to toggle data on and off every time you want to look something up.

Is maps showing up on your battery stats and you're not using it? If so, simply open the application. It should say "updated to the latest version" or something like that. If this is happening, this will solve your battery problems.
Happened on my Galaxy Nexus and was happening initially for this phone too. Hope this helps someone.
Modem Fast Dormancy Monitor Service Not Responding.
Me and my wife both updated to KitKat on our Razr M's. I like it so far. The pop up about modem fast dormancy bothers both of use. When you look under battery, it uses more battery than other apps. I force stop it, reboot and it comes right back. A chat on Motorola web site sugested to wipe partition cache. The link that was provide gives the wrong instructions. KitKat using the power and volume keys has changed. They forgot to tell some people. That didn't work! I sent a long email to Motorola telling them that someone messed up or they did this for a reason! I guess if you get mad enough you'll just buy a newer phone. If that one thing is fixed, we would both be happy. The white background in text take some getting use to also. I hope Motorola will help us, but I kind of think Razr M's will be considered OLD! They are betting we will junk them for a new model.

Sorry! My bad. I didn't notice it was closed. Why do they not take old olds off line.
Hey guys,
I am having a few bugs with the battery indicator on my Tegra Note 7. It is always freezing up at random percentages and does not give an accurate reading. For example it thinks it is at 81% right now, and if I were to reboot it it will only actually be at like, 40%. I was just wondering is this a bug with only my device? Or are other people experiencing the same thing? I'm at thempst recent OTA, but its something I've been experiencing since I first opened it.
Also, like many others have noted, when I updated to Android 4.4.2, the battery seems to drain A LOT faster. Like, its down 10 percent in 30 minutes on balanced battery. These bugs kind of make me want to refund it and buy an nexus 7 instead. I've only had the thing for about 3 days.
Quick update, I'm just about to do a battery calibration to see if this fixes the wrong reading issue. If not it may be a hardware defect.

That's weird, because ever since the latest OTA, my battery life has been stellar! Sitting in standby, it'll go literally a week without a charge, and during use it seems quite reasonable. I wonder if it's because I did a full factory reset after the update... I've had mine since launch, and after so many updates I figured it might be a good idea to do a full reset, and it cleared up a lot of my issues.

That may be a good idea. The reading issue is something that has been going on since the first day I got it. I had to walk to the library to set it up with all my games and such, and the whole time (about two hours) I was there I thought I had a charge 57%. I went home and rebooted to realize the battery was actually only at 8%! Since the calibration, I haven't seen the issue as of yet, and the battery seems to be working a lot better. I may try a factory reset however because I am having a few unrelated touch screen issues and stylus issues.
Seriously, what's wrong with the Z5 compact? the Z3 compact was a longhaul wonder but I had to upgrade, since the back cover piece of "glass" was so fragile, it broke several times without much or any force exposed to it. Exchanging it anyway never got it waterproof again.
But the longer the more updates are coming to the Z5 compact, the less it's battery holds and I only got it since March this year!
I make it barely through the day on one charge with 1h of screen on time max!
As you can see in the attached screenshots today it's down to below 30% at 3 o'clock in the afternoon after disconnecting it from the charger this morning at 8 o'clock and I haven't used it much since... 15 minutes of listening to music, occational web searches and e-mail reading. I'm on the latest official Marshmallow (32.2.A.0.253), no root, no bl unlock, all stock!
what shall I do?
sorry for venting a bit...

The latest is .305, upgrade, debloat, post results.
Im having similar issues, same version. Checking for updates tells me that my phone is at the latest version
With latest soft . 305 the battery is better than before.
Same here, this phone is melting the battery like butter under the sun.
Impossible to determine which processus is faulty but it wasn't the case some weeks ago.
Update your phone to .305 (flash it completely)
works on my machine
So I factory reset over the weekend, and did not turn device encryption back on (I had it on previously)... and I've noticed hugely improved performance and battery life, and drastically cooler temperatures. On one hand, it could be that the factory reset cleared something that was causing issues; but on the other, device encryption, by definition, requires more CPU cycles, which will heat up a device and cause battery drain and slower performance.
I know that it sucks having to make the trade-off (if device encryption was a contributing factor), but if you have encryption turned on and have problems with the phone getting really hot, performing poorly, or draining battery, consider turning it off.
Perhaps it would be less of an issue with a different processor, but Sony did stick us with the 810, so... lol
Where in the menu is this encryption?
Yep, hard reset cured my z5c too. Something kept it awake and I couldn't find what. It was over 30 proc. battery drain over night, now it's 3 and 3-5 hours screen on time.

It's not turned on by default, so if you didn't turn it on, it's probably not on.
It's under the Security settings. There are buttons to "Encrypt Phone" and "Encrypt SD Card."
Ever since i upgraded to 32.2.a.0.305 which was a mandatory update; my battery drained a lot faster similar to TS. So I have to factory reformat again? I've done this 3x already since I got my phone back in February. I'm so frustrated right now with Android; I don't even know who to blame; google or sony.
My phone was ok before the october updates; the low power mode would kick in and i could see the power graph go more horizontal as time has passed. Now it is a direct slump down from 6pm (full) to 6am (15%) and I was asleep during this time.
reformat? that will take considerable amount of time. I'm a working professional and I have a family with responsibilities. iOS is looking more and more enticing as the days go by as I use this phone.
I was happy that the z5c has a larger battery and can charge 50% faster (with qc 2.0) but it happens to also drains 2x faster.
Even if android is a superior OS than iOS (IMO); it is so very unreliable and unpredictable. I just want to feel relaxed (peace of mind) that my phone will be available when I need it the most. Now every time I go out I have to think about not forgetting to bring a powerbank; so much for a compact android phone. my powerbank + z5c is bigger than the iphone plus.
I've solved the problem, I'm back on Lollipop 5.1.1 with the 32.0.A.4.11-R3B FW.
The difference is really huge whether in terms of battery, reactivity and useful features. Today the phone have used 15% of battery where it would have usually used 45% in the same time on MM.
I'm like Chadie, I don't know who is to blame, Sony or Google, but this MM fw on the Z5C is a shame.

Yes, it sucks having to factory reset, but I'm a working professional, too, and I found the time to do it on a Sunday morning. It's worth it. Google can restore most of your settings and apps, you'll just have to manually reconnect Bluetooth devices and set up your home screen again.
I was really shocked with the battery life coming from 4.4.2 on my z1c HEAVILY modded/tweaked was getting 2 day battery life and upto 9hrs screen on time (NINE HOURS!).
But yeah I now got the z5c (r.i.p z1c best phone ever) for 60 quid brand new because my mate didn't want it anymore got iPhone instead lol but since I updated to .305 over the past few days the battery has REALLY improved like it's magically calibrated itself or something and I'm getting comfy 1.5days out of it, I don't know how much screen on time as MM doesn't show you anymore but hey I've noticed a massive improvement.

Download GSam Battery Monitor if you want that functionality back. It'll tell you screen time, as well as all sorts of other usage metrics that impact battery life.

I can confirm that factory reset is unfortunately the best solution.
For my work, i had to update a dozen of Xperia M4 aqua, which is famous for poor memory available ( 8gb version).
So i compared reseted and not reseted available memory after update and can tell you there is a big difference.
That's why i now make my best to convince users to factory reset after update.
An updated system will never be as efficient as a clean installed one.

Just following up... after the reset, the battery life, especially at idle, has been rocking. Here's last night while I was sleeping (note that I do not charge my phones overnight, since it's bad to charge a Li-Ion battery to 100% and I wouldn't be awake to disconnect it before that happened):
This is on build 32.2.A.0.305, and the phone is not rooted (it is completely stock firmware).
Compared to z3c this phone is an epic fail.
HELP!!!
I picked up an H918 for my wife to use on T-mobile USA. Since it was used, I also got one of the extended life 4100Mah batteries to hopefully make it last at least the entire day without topping off the charge. She usually averages around 4 - 5 hour SOT, so this seemed like a good option from what I've read, and fits in the original door so I can use the wallet case she wants with it.
But man, her battery life is TERRIBLE! I checked with Accubattery, and it reports that the battery is charging within 99% of it's 4100mah spec, so I don't think its a bad battery. Yet, she can barely go 12 hours with just under 2 hours SOT before the phone dies!
She is unrooted, running stock Oreo.
I installed GSam Battery Monitor and used their ADB commands to give it permission to record deep statistics w/out root (pretty cool, never did that before). I ran it for a little while this morning. Within 3 hours 40 minutes off the charger, she was already down to 72% with barely any SOT. I'm attaching screenshots of the app usage and doze screen (sorry for the phone-snapped-of-phone picture, it's my wifes phone like I said, so it was easier to just snap with my camera than take a screenshot and send it to myself to post).
Maybe I'm not reading this right, but it seems like something is keeping her phone from sleeping. A big culprit seems to be call services, and in my location settings, I noticed it mention that LG IMS was doing a lot of heavy battery drain with location related inquiries.
I thought maybe it was related to WiFi calling, so I turned that off. Cell reception is average.
2 hours later, she's down to 50% so that wasn't it. I don't know what else to try other than hard reset, but we literally just got this and set it up 2 days ago, and its been like this from day one. I don't see why it would be any different the second time around.
It's likely a junk battery. It's really hard to get a good oem replacement battery.
If you shop Amazon look for a Taeozi 4200 or Shemnz 4200. They both have 2 year warranty and decent reviews here on XDA
The Perfine 4100 is also highly recommend
Any Li-polymer should be better

When I bought my wife's phone it had a battery drain/overheat and wakelock issue as well. I fixed it and haven't had an issue since. Here's what I did to fix it:

I did my homework first and got the Perfine from Amazon, not a no-name junk battery. When I couldn't fit it without removing the sticker, the seller was really helpful and actually offered to replace it after checking first that it fit in *THEIR* V20 at the factory. Really solid customer support. And according to Accubattery, it really is the capacity it says. Or at least within 99% of it (I think it estimated 4080 or something like that). So I don't think that's the issue.

That's actually really interesting- I did take apart the phone to do the thermal mod thing (wiped off the dried up pink gunk and put a thermal pad there), but it seemed pretty clean otherwise inside when I did. How on earth did you figure out that was the problem?
After speaking with some folks on Telegram, Reddit, and other corners of the internet, I have a different theory. A bunch of people told me to let the rom "settle", that battery life is never good after a fresh format or new rom flash. Honestly, the critical thinker in me says that sounds like nonsense. I've never heard of this before and I've been flashing roms for the better half of a decade. I'd think after it takes the time the load up your apps and settings and configure itself, it would be done. But I Googled it, and it seems to be a hotly debated subject.
Those that swear by it claim that whenever you start fresh or flash a new rom, it takes anywhere from one to a few battery cycles before the kernel calms down. Perhaps it is doing some sort of internal calibration based on your battery life and system demands or something like that. The theory seems to be that the Kernel doesn't allow the CPU to fully doze until it is done with this process, which sometimes takes days. I don't know, but the more I read about it, the more it sort of started sound plausible. When I got the phone, I tried out some things on it myself without a SIM card first, just to make sure everything on it checked out before giving it to the wife. Then, I did a hard reset, popped in her SIM card and let it do its thing. That's when we realized battery life was pretty terrible, as after 10-12 hours she already needed to charge... and this was on the 4100mah perfine!
I tried another hard reset, and when that didn't fix it, I decided it was time to root and see if I could get to the bottom of the bad battery. It seemed the kernel was where a lot of it currently went according to battery stat apps. After downgrading my H918 to Nougat so I could install TWRP, I promptly flashed Alpha Omega Oreo 20H and restored her apps. Turns out the next morning we couldn't sync her smartwatch, somehow we broke bluetooth (going into BT settings would crash the phone everytime). So weird, and while we were at it the battery life still wasn't great. So I did a hard reset that evening and found that even with nothing installed, BT was borked. (looking back at it, I think I should have flashed an Oreo rom like the stock 20H rooted first, and THEN the AO rom. I think going straight from nougat might have led to a driver mismatch or something)
Anyway, after that didn't work I flashed the stock rooted 20H rom, and lo and behold bluetooth and everything else is working again! But the battery has been bad all along and is still doing its generally suckiness thing.
BUT... as someone pointed out, if this kernel settle thing is real, I've been pretty much flashing and resetting this thing every other day. If roms need to "settle" first (still a debatable subject), than I never really gave it a chance yet and that's why I'm constantly seeing battery drain from things like Kernel even on different roms! And @pistacios, is it possible that you were having a kernel do the same thing since it was just reset and it just so happened to be that when it calibrated itself you thought you had fixed it by cleaning out the USB port?
All I know is I'm going to give this a couple of days before deciding on a plan B. Seems too simple to be the reason, but hey- I'm desperate.

Ive experienced ROMs settling in and battery stabilizing after a few days. But this was pretty far back with the HTC M7 and M8. Most modern phone's I've flashed pretty well settled in within the first few hours. The battery life on this phone was never amazing. It was good to just Ok for most when it was new.
If you flashed the stock rooted rom and still had bad battery life, I still suspect the battery itself. I still recommend one of the battery I listed earlier. If the perfine didn't work out try a different one.

Right, with the stock 3200mah battery. With the Perfine 4100, a lot of reports are saying 6-7 hours SOT or at least a full day of regular use. That's good enough, really. Mine is dying at half of that. I'm wondering if I have faulty hardware. I could put the stock battery back in and see if it dies much sooner.
I'm actually wondering if someone can check their mA use per hour with the screen on vs off, and I can see if the numbers make sense on mine. Accubattery is pretty good at the math.

Phone was up and running for 2 weeks, so it wasn't due to fresh reset.
GSAM battery monitor showed kennel wakelock, something about USB OTG in the top of the list, so I figured the port was my first check for a problem, and it was. It wasn't obvious that there was dirt or foreign matter in there, because it looked clean. But sure enough, after the light brushing with 94% alcohol, the problem disappeared.
I'm not saying this is definitely your problem, just throwing it out there.
