Hi all,
Basically a few days ago I updated the firmware via Kies from 2.2 to 2.2.1 on my Galaxy S. However, I instantly noticed a huge decrease in battery life - 50% gone overnight when in standby! So I factory reset the phone and had everything disabled - the phone only lost 10% in 24 hours. So I decided to try and eliminate the possible causes so first I turned on wifi and within 2 hours I have lost almost 30% of the battery life with no usage so wifi seems to be the culprit
In the wifi menu network notification is off, however, the device seems to be scanning for networks every 5-10 seconds even when connected! I had no problems like this on 2.2 where I could comfortably get 2 days usage with wifi on. Also as I would prefer wifi to be on constantly when connected I would prefer not to change the wifi sleep policy. Any suggestions would be much appreciated
Many thanks, and sorry if there's similar thread already
which version of 2.2 did you have before?
try a flash back and see what happens.
Or try to drain battery (do not charge till 1% or almost dead) then full charge it.
Always happen to me when I flash my phone to a new ROM.
Thanks for the replies. I've tried leaving the battery till it was almost drained but maybe I'll let it go completely flat and charge it see if that makes a difference?
Also trying juice defender from the market to see if that helps. Not sure if it is a problem with the firmware though been looking around and a few people seem to have had the problem with no real solution
Might have to go back to 2.2 but would prefer not to as I've noticed a big decrease in lag on 2.2.1. Also can't remember what version of 2.2 I had I'll see how the battery life goes over the next few days after trying a couple of drain/charging cycles hopefully won't have to downgrade it. Come on 2.3.2
Thanks for the replies so far
Battery Bug is Major issue with all the versions of 2.2.1, Battery life is very bad. Even the Browser is worst in 2.2.1. May be in 2.3 it will get fixed.
I have tested all the new releases of 2.2.1. I found its smooth and fast.

Very very bad idea to let the battery go completly flat, it's the best way to damage it and even lose 20% of his initial capacity. Never go under 10%.
To calibrate it properly, wait 10% turn off the phone, fully charge it, restart. (do it again 3 times).

The battery is calibrated to do this already, the charging circuit will not allow power to the device unless there is a certain amount of charge in the battery. It's there to protect the battery from this exact eventuality.

That's how it's supposed to be in an ideal world.
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )
That's all folks! Please report your success / lack of such here. Also, feel free to ask questions, and I along with other users with answer them according to our ability.
I will later add a section on "good practices for battery usage" with tips and tricks.
Cheers!
Attached are screenshots of my results after calibration: This was under moderate usage. Pretty damn good if you ask me.
Post-calibration methods of improving Battery Life
Updated: Post#2 will explain how to solve battery drainage problems when recalibration wasn't enough. It will also explain how battery reporting works, common practices, tips, tricks, etc.
Battery Tips / Tricks / Common Practices
Important things to know:
1. It's important to understand how battery indicator on Android works and how Android manages / reports your battery life. Please read this article:
Your Smartphone’s Battery Gauge is Lying to You (and it’s not such a bad thing)
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
2. Li-ion batteries used in modern smartphones don't have "charge memory". Partial charges won't hurt the battery (e.g. charging from 60% to 80% or from 10% to 50% etc). Feel free to give your phone small charges whenever you have time and need the phone to last longer.
3. Smartphone batteries don't like to be completely discharged or to be kept at 100% capacity for extended periods of time (this actually damages batteries over time). But worry not, the battery software prevents this from happening for you. That's why some of your phones never get to 100% or drop from 100% to 90% minutes after you disconnct the phone from a charger.
4. All batteries gradually lose a small percentage of their capacity after a certain amount of charge cycles. It's a natural part of life. It's always nice to have a spare battery or to purchase a replacement when your current battery isn't to the task anymore.
5. Don't pay much attention to the battery %, just use your phones. I know it's very tempting to track your battery usage every 15 minutes and try to find problems. Been there myself. Thing is, if you do this, you might start thinking you have problems, when you don't have any.
Bottom line - just try to use your phone and not mess with the battery unless problems become really apparent.
------------------------------------------------------------------------------
Other proven ways to improve Battery Life
If you have re-calibrated to a full capacity (4200mv) but your battery still drains terribly - follow these steps to pin point the problem.
1. Find which app / process is draining the battery.
If you get lucky, the infringing app will show up directly under the stock "Battery Usage" statistics. However, in most cases "Battery Usage" isn't very informative. Most people report that they only see "Phone Idle" consuming most of the battery without much insight into the details.
Things to do:
- install Watchdog, go to preferences, set CPU threshhold to 20% (or even lower if it's not enough), check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20%(or even lower if it's not enough) as well. Run it for a couple of days.
If you start getting frequent Watchdog notifications about a certain app breaching the threshold - uninstall it, find an alternative.
- install BetterBatteryStats from here -
http://forum.xda-developers.com/showthread.php?t=1179809 run it for a couple of days and monitor apps / processes that are using up more wakelocks than they should.
Once you find the infringing app - uninstall it, if it's a process - find out if it's safe to stop / freeze before doing anything.
2. Freeze bloatware aka "stop the problem before it becomes a problem."
Unless you are running CM7, your rom is based on stock 2.3.4 and still has blur in it. Blur apps and processes might be running without you even using them and sucking out precious batter life while they are at it.
Things to do:
- Get TitaniumBackup, freeze all bloatware that is mentioned as "safe" in this thread -
http://forum.xda-developers.com/showthread.php?t=1182663
Use your phone for a couple of days afterwards and watch for improvements.
If these software tweaks aren't enough, the problem might be with your system setup. Go through these steps which should hopefully fix your setup in favor of awesome battery life:
3. Flash a custom kernel, set up battery saving profiles.
Many people have reported success with this step. Custom kernels are not just for overclocking. A custom kernel with smart profiles will definitely give definitely extend your phones operating life during the day.
Things to do:
- Get a custom kernel., the popular choice on here seems to be faux'es kernel, so I recommend it -
http://forum.xda-developers.com/showthread.php?t=1156040
Get one of the battery saving SetCpu profiles along with it. Basically, a good battery saving profile looks something like this:
- absolute minimum CPU clock with screen off (something like 275 Mhz)
- lowering CPU clock with temperature > 50C (something like ~800Mhz)
- lowering CPU clock when battery < 30% (something like ~800Mhz)
Many people reported success in using such profile for lowering "Phone Idle" drain.
4. Flash a different radio.
WARNING: Be extremely careful with this. Flashing a wrong radio is the right way to hard brick your phone.
Although some people are reporting to have fixed battery drainage by trying out a different radio, I seriously wouldn't recommend going on a flashing spree unless you know what you are doing.
My advice here: flash the latest 2.3.4 for your carrier if you haven't yet. From there on, experiment at your own risk.
5. Disable Data and Wifi when idle either manually or with an app."
I seriously get surprised every time someone says they have a horrible battery life, when they keep an internet connection on at all times. Constant data always = battery drain.
Things to do:
- use apps like Green Power to disable data / wifi for you when you are not using it
- learn to turn off your internet connection manually
6. If all else fails - start over from scratch (read: clean install a rom).
I've heard reports of people getting better life with Froyo than GB, or that a specific custom ROM solved their problem for them. A million dollar question: if it works for you, why not use it?
Things to do:
- try a ROM without blur, like CM7
- try Ninja Speed Freak (developer and many users reported great battery life)
- if battery life is your top concern - try Froyo

Are you using stock Orange 2.3.4 rom?
If yes, your Rom might not have the battery jumping problem. You can still use this guide without the battery fix to recalibrate.
Let's wait for someone with Orange 2.3.4 to confirm if jug6ernaut's CWM battery fix can be used or not.
Indeed, I have not the battery jump issue, but I'm exprimenting some weird behavior...
like when I restart the phone, it shows about 10% higher than before. I tried this multiples times yesterday. When it was about 40%, it starts to drop suddenly, 'till it got to 18% and get back to normal decrease to 4%, 2~3 hours later...
See the images attached, the red circles are the times I rebooted it and the blue arrow is when it drops suddenly...
Question on step 4. To confirm, we shouldn't click on anything in BatteryCalibration, all that needs to be done is take note on the MV number, correct?

Did it only start doing this on 2.3.4 or you haven't checked before? Anyway, I would do the calibration to see if it changes anything.

No clicking in step 4. Just write down or remember the MV number.
Yes it just starts when updating to 2.3.4... In the first days I got the impression of lower battery level, so reading the forums I saw the restart/level change problem, and tested it

You probably updated to 2.3.4 while not at 100% battery level, and it messed up your battery stat. So, yes, do all the steps in this guide except for jug6ernaut's battery fix part.
thanks, ill give this a shot....again.....tonight and hopefully it will fix my issue.

I'm on a rooted stock GB and I'm having the problem where the battery usage stats are inaccurate and won't got below 90% after using it all day. This all started after I used Battery Calibration. Do you think that this would help correct the problem?
Edit: Also, would I need to complete all of the steps including the CWM part? I haven't flashed any roms yet, so I don't know if this would be necessary.

Seems like you used Battery Calibration while not at 100% charge and your battery stats got messed up.
The reason I recommend using CWM is because the battery stats file is created on each boot. So, with my instructions you can charge the phone to 100% while it's off and wipe the messed up stats before it boots.
You can try using my instructions, without the CWM part, except you need to wipe your battery stats with Battery Calibration app after step 4.
lol i left pandora on since this morning and its only at 67%. ugh, when i wanna force drain the battery it goes slow as hell but when i wanna conserve battery live for usage it drains quick. hahaha.
I just flashed navalynt's πCrust rom fully charged, cleared stats through cwm, booted and now i'm close to 3days.

lol yes. I used video playback to drain mine. But if it's really a PITA, you can always just leave it till tomorrow to discharge naturally.

Yep, that's why flashing only when at 100% charge always pays off.
I get the same results by booting to CWM, wiping battery stats, rebooting, starting Battery Calibration, plugging phone into wall charger, charging to 100% (4197mv for me), and then calibrating with Battery Calibration. I start this process at any battery percentage, and have been doing this for a long time now. I have never had to deplete my battery until my phone shuts off, and get great battery life.

After the calibration I had 4200mv, so it seems like you are doing things right in regards to the battery.
"Taking the battery out and putting it back in" trick works wonders though in restoring battery life to maximum state (if you had it decrease for some reason). I've tested it multiple times even back when I had the Milestone.
I'll post everything I've tried and everything that's gone wrong here.
So initially I purchased this phone off of a friend nearly brand new, the screen had broken and had been replaced. Otherwise the phone is in perfect factory condition.
I unlocked the phone, and am using it on Rogers. APN settings working perfectly.
I installed GOLauncherEX on the phone as Motoblur wasn't doing it for me.
Battery life was crap (lasting hardly 3 hours and dying while I sleep). I found that Motoblur HOME had been running alongside GOLauncherEX. At first I simply uninstalled the third-party launcher, but then opted to grab LauncherPro+ and HomeSwitcher. This dramatically improved battery life.
Lately, I've been having issues once in awhile again. Mostly if I leave the phone unplugged while I'm sleeping (fully charged when unplugged) and we'll use the timeline 3am - 11am. It would either die completely or drop to around 15%.
As long as I could have enough charge to last me through work, I was fine with this as it was way better than what had been happening before.
This morning something extreme and unexplainable happened.. and it's the first time I took a look at the battery usage meter to see what had happened. Picture is below.
If someone could offer some tips or help that would benefit me even the slightest, it would be very much appreciated.
My bad for sneaking a link in, but it was the only way to show the issue.

Calibrating is something you may need to do after flashing a ROM, you can search and find a guide or you can use this app.
I have not flashed any new roms and I don't intend on doing so, but I'll check out the app you posted.
Thanks for your help,
any new ideas are still welcome.
The benefits of battery calibration are not limited to only if you flash a new ROM. Battery calibration should be the first thing you try if you are experiencing battery troubles imo, and there is allot more in depth information in the guides you could search for.
There is one more thing I can think of you can try, download Watchdog and see if there are any malicious or poorly written apps burning up your cpu/battery.

Maybe unlock the bootloader and flash a custom rom?
Go into account and sync and shut off background data. I was getting. 10-12 hours battery life and now over 30 by just doing that. Worked for a buddy at work too.

Radio is key. After I flashed radio 1.77.30p, my phone can easily using 3 days without freeze anything.
Do not use 1.97 radio and don't use task killers. 2.3.4 gingerbread does a much better job of killing tasks than Froyo did and it's unnecessary. Also, turning off background data is not necessary.

I would say it is. Apps including google will try and update and locate your phone via 3g and gps when its sitting there idle. Its not necessary if you only install apps that dont use background data, or disable them individually but some dont allow it.
I still was able to get 15 hours with data enabled and over 30 with it disabled. There is a huge difference there. I just have to open my yahoo now to update it which I dont mind.
While I appreciate everyone's replies and help, has anyone actually looked at the picture I posted?
As much as I am most definitely interested in prolonging my battery life, that picture is showing a sudden drop from 70% to completely dead, idling, screen off, while I'm asleep.

I would purchase a new battery from Motorola, It looks like your battery has one or more bad cells in it. Only thing that really explains it. Even with everything turned ON as far as data - the battery should not drop that far that fast.
i'm not entirely sure whats going on with the charge level dropping so sharply. Either something is draining your battery big time or the readout when it says 100% is incorrect.
I had issues with the battery up time as well. In my case, the battery wouldnt last more than 8-9 hours. I had to charge it two times a day. Once overnight so its 100% when i go to work and again as soon as i get home. If i charged to 100%, unplugged and went to bed, it would be at 15-20% when i woke up.
The last time i went abroad, i left the radio turned off completely. I noticed that the battery held its charge for about a day and a half.
Now i did root, unlock the BL and install CM7 on my phone. It seemed better but not that much. After i setup the phone to NOT use my 3G data connection while my wifi was on, i noticed that i was getting great battery life when i was at home but still rubbish at work.
I'm doing a test right now to see if this makes a difference or not. I have turned off data on my phone all together this morning. I charged it to 100%. Normally after 6 hours at work, my phone is at about 30-35%
Right now its sitting at 75%
the 3g is whats killing the battery, on my phone anyway. I will see how long the battery lasts without turning on my data at all. Then i will compare that with how its like with background data turned off.
I would suggest you try re-calibrating your phone's battery, i use battery calibration from the market. Then either turn data off altogether like i have or just turn background data off as the others have suggested and see what kind of a difference it makes.
While i realize you dont want to, it may help further to have a ROM like CM7 installed as it wont have all the bloatware that can further reduce the performance of your phone. You should definitely give turning the data off a go to see its the culprit before you go spend money on a new battery which may or may not fix the problem.
Best to isolate the root cause before you spend money on fixing it. If turning off the data doesnt do it, then you very well may have a battery problem.

I'll definitely try everything you've mentioned, I did calibrate my battery since I first started this topic. I'm not sure if there's a difference, if there is, it isn't noticeable. My phone died last night, and I charged it overnight again so I haven't had a chance to see if what happened the other night will happen again. Soon enough, I'll post details if I notice anything peculiar.
Since you said you bought the phone off a friend I would like to make sure you have the right battery.
The battery "must" be of the following to show the right charge level, otherwise it might appear the battery discharging very quickly.
The part/model no.: SNN5893A
Manufacturing Date: ??/April/2011 or onwards
In regards to the poster above who mentioned shutting off background data, my phone lasts 17-19 hours running CM7 with nothing frozen, background data on, and I record quite a bit of video + pictures every day. I don't use task killers either. So I'm thinking that maybe the background data thing is either actually covering up a radio problem, a carrier issue, previous ROM information leaking through, or a faulty battery as stated above that could possibly need replaced.
My Nook Color with internal CM 7.1 shuts off if not plugged in. I had CM 7.1 on my Nook Color for months with out any issues then about 2 weeks ago it started to completely shut off if not plugged in. I didn't install any apps or it wasn't changed in anyway, it would just began to shut off. I then decided to install CM 7.2 to resolve the issue but it does the exact same thing. I have no idea was is going on.

Sounds like battery issues. By shut off, do you mean just goes dead instantly as soon as you unplug it? Or some other thing?

Yes, it goes dead.
What does your battery show? Percentagewise, that is. Try booting to CWM and doing a wipe battery stats.
It goes dead instantly and the battery status is 100%.
I wiped the battery stats and it still shuts off.
I'm having this exact same issue. I checked using one of those battery calibration tools from the app store, and my battery is reading 4207mv. Not sure what is going on but I don't really want to have to replace the battery on this thing already. Anyone have a way to actually discharge the battery while it's out of the nook and see if it can get re-calibrated that way?
Try backing up your system and then reinstalling stock. It has a small zip file (charging.zip) that goes on the boot partition and gets activated by the system when the system thinks it needs it. I don't know if it has anything to do with problems you guys are having, but we are grasping at straws here. I have a version of stock that has been modified to be flashable with CWM. Get it here.

Cool, I'm downloading it now. I don't mind wiping this device since it's just a test device, is there any reason to backup /system other than to save my current rom? Also, if I flash that modded stock, does it already have root and will it affect my recovery or will I still be able to boot to twrp?
Thanks

The backup is just so you have yourself one. If you don't need it don't do it. It is vanilla stock, not rooted. And your TWRP will be gone. Stock recovery will be there. That is part of my reason for suggesting it. This just a test to see if the stock system fixes your problem.So maybe a nandroid backup is good so that you can just restore the nandroid and everything is as you had it, TWRP and all.

Sounds like a plan. I'll give it a shot in the AM when I get a chance to put it back together. Since it was acting up I decided it would be a good idea to do a little teardown of it and see what was inside.
Thanks

Well, at least you have stock on it if you want to take it to B&N for them to look at. If still under warranty, maybe they will do something.
I tried reinstalling stock as well, it boots normally with it plugged in and still dies when unplugged but I'm gonna try to recondition the battery. With a little luck I might be able to get it back to working. I found some useful info for people about batteries that would be good to know for your nook. I didn't know these things before hand that that's probably why my nook's battery is dead.
Taken from here:
3: Allow partial discharges and avoid full ones (usually)
Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it’s better for the battery to use partial-discharge cycles.
There is one exception. Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device’s power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated.
4: Avoid completely discharging lithium-ion batteries
If a lithium-ion battery is discharged below 2.5 volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger will be of no use. Only battery analyzers with the boost function have a chance of recharging the battery.
Also, for safety reasons, do not recharge deeply discharged lithium-ion batteries if they have been stored in that condition for several months.
5: For extended storage, discharge a lithium-ion battery to about 40 percent and store it in a cool place
I’ve always had an extra battery for my notebook, but it would never last as long as the original battery. I know now that it’s because I was storing the battery fully charged. That means oxidation of lithium-ion is at its highest rate. Storing lithium-ion batteries at 40 percent discharge and in the refrigerator (not freezer) is recommended

I've let this one sit for months on end being dead, then I would fully charge it and use if for a day or two trying some stuff out for work, then let it sit and slowly discharge and be dead for weeks if not months again. Probably not a good idea.

Thanks catawalks for that very informative link. I am going to add that link to my tips thread for other users to read.
You might want to install an app called Battery Monitor Widget Pro by 3C. I think they have a free version on play store. It gives you useful info about you battery's condition and charging history.
Keep us posted about your success or failure about reconditioning your battery.

Feel free to use it. All is good. I'll give that app a try too and will definitely keep updating with status on the battery.
Hello, I have a Moto X Style model xt1572 and after upgrading to Android 7.0 (through OTA) I noticed that my phone's battery is losing its charge. Unfortunately, I did not notice if this same problem occurred before the update.
The problem occurs when I reboot the device (up + down + lock), it loses about 8 to 10 percent of the battery charge, sometimes even more, but if I turn it off and on again then it does not lose the charge .
As an attempt to solve the problem, I rooted the device and installed a battery calibration app, the app informed me that the battery health is good, but I still have the problem of the loss of charge if I reboot the device .
Yesterday, as part of my tests, I charged the phone thro 100% battery (from 12am when it charged 100%) and did not recharge the battery until it was empty, which came at 12h12am today, but i almost not touched my phone yesterday because of my job.
Still as a test, today, I loaded my device up to 100% and then turned it off and on, again, there was no loss of charge, so I rebooted the device and guess what? It dropped from 100 to 88%, I attached some images to the end of the post showing the full load and minutes after restarting the load drop, and also 100% of the load and minutes after switching off and on again with 100%.
Anyone who has upgraded to version 7.0 could test and see if this load loss also occurs?
I believe that it is problem in my battery, but I would like to exclude all possibilities before investing in a new battery.

Did you do a cache wipe and/or factory reset? I would suggest it, lots of major changes under the hood... A factory reset is recommended after any major OS version upgrade. Any troubleshooting prior to that would likely be a waste.

You mean you unlocked the bootloader after you had nougat and that did a factory reset? Then no, just do a a cache wipe. If you did the reset before Nougat, yes, do it again.

Yes, nougat first, after that i unlocked the bootloader. I tried to wipe the cache as you said and did not work too, dropped from 58 to 23%

GSAM Battery Monitor
Wakelock Detector [Root]
i installed both, but none of them show me what's consuming my battery when i reset my phone, i charged 100% them i reset it and goes to 84% and the apps said that i lost just 1% even it showing that i have 84% =/

Take a screenshot of GSAM and WLD after it's down to around 40% or lower and post it please.
Hello i am facing the same problem. So i reverted back to marshmallow and it fixed i think. in nougut it drains battery even when you phone is idle thats what i think. And there is another thing moto x style stores it battery info in a pertition names logs-charging.(i am not sure) but maybe in nougut update it gets reset so battery calibration gets wrong and your phone thinks you battery can store 3000 mah when your battery can store less than 3000 mah, for an example like 2700 mah after some month of use. So when you restart your phone your phone checks battery power remaining by measuring voltage and it changes the percentage to show remaining battery. Well i can be wrong. And sorry for bad english.

Your phone is losing charge with normal use or only when you reset it? Because mine loose charge only when i reset it apparently, with normal use its seems to be ok and discharge as it should.

Is this an official OTA update you got on your device... or did you have to force it somehow?
Your radio usage is crazy high, 30% of your battery usage was by your radios... Just for reference, mine is RARELY ever over 10%, usually around 6~7%

Yes, original OTA update without any mod on the phone. Is Phone radio about the signal oscillation? if is, the reason is that i live on Brazil, our cell phone antennas here is not the best and on my work (where i pass almost all day) theres problem with signal, some operators not even has signal there in some points of the office...

Yeah, that's probably why... The worse the signal strength/quality, the harder the radios have to work.
How old is the device? If it's exceeding 18 months, probably a good idea to think about replacing the battery and back.
For my battery is really really worse on nougat! Like 1hour less SoT or more, a lot less active too. I have to charge it 3 times a day...
