I've searched about a million times in 900 different threads, but I still can't find a fix to this issue.
I first noticed this when I flashed MIUI onto my phone. I would get cell standby and cell idle at about 40-50% of battery usage each. Display wouldn't even be shown on the usage! I then figured MIUI wasn't worth it to me, so I flashed CM7. I tried both morfic's and faux's many kernels, nothing seemed to fix the issue. If I would turn the airplane mode on, I'd get battery drain of only like 2%/hour.
So I figured there was something wrong with the CM7 port, so I tried g2xtreme and other GB ROMs, same thing. Finally, I just checked a froyo ROM, same thing again!
So at this point I'm clueless and thinking the phone is completely a POS, but anyways. I'm about to nandroid restore stock 2.2 firmware, and try updating through the LG Mobile Support Tool.
But I have my doubts that this will fix it. I'm curious though if maybe I'm getting this drain because I'm with WIND Mobile in Canada? And this is for the T-Mobile G2X (they're the same phone and both companies use the same radio frequencies). But maybe there's something written in these ROMs to tell the phone to look for the T-Mobile network? Which I obviously won't be able to find in Canada.
Can someone help me locate these settings, if they exist? Or can someone with a Wind phone maybe toss me the WIND stock firmware? Or let me know what ROM they're using without said issue?
Thanks guys!
Edit:: In low signal areas the phone drains like 15-20% per hour, in high signal areas the phone is still pulling like 8%-10% an hour and I'm not even using it! And the weird thing is it only shows 1% time without signal! Something is seriously wrong with this firmware.
Search for betterbatterystats on XDA, install it, enable battery monitoring in MIUI (if that's your daily rom), leave your phone alone for a few hours, then open BBS and look at the partial wakelocks under "since unplugged." There you'll see what's killing your battery.
Everyone experiences worse battery life when reception is bad, but you are still getting terrible drainage in good areas, which means there's something other than reception killing your battery.

I tried that before, and had a crapload of apps "frozen" with titanium backup.
I'm going to try this again, and I'll post a screenshot this time because I don't think I actually understood what betterbattery stats was trying to tell me last time.
If anyone can help me decode it later that would be great!
Just noticed that there's barely anything under partial wakelock that's noticeable.. RIJL Telephony is the highest with 1m 1s 15%.
But it's not increasing very much, only when I get a text message. However, I've dropped about 7% since my last message, and cell standby is increasing climbing up my battery usage from 33% to 42%. It went from 620uah to 657uah.
Edit:: I reset battery stats cause I was unsure if it was corrupted stats. I started at 17% 40 minutes later I'm at 12%. Phone was off 90% of the time. I made a 2.5 minute call and it used 41uah, while cell standby still dominated with 65uah.
However, I turned my phone on for 5 minutes, making total usage 45 minutes, but had the brightness set to max, and in that five minutes it only used 1uah.
Am I missing something here? At this point I don't know if my numbers are normal or not anymore... I'm going to try draining the battery, charging to full, wiping battery stats, and calibrating and see what happens but 65uah to 1uah is a huge difference, I would've thought display would use a bit more than that.
I noticed this morning that having the phone with airplane mode OFF, that my battery dropped 10% in 57 minutes, and after turning the airplane mode ON, the battery dropped 1% in the next hour and 30 minutes. I checked battery stats and nothing was waking up my phone. Anyone have any other suggestions?
I'm going to flash miui and leave it without any apps installed then try this experiment again.

I find these threads interesting because I am always looking for better battery life.
I am running EB 2.3.3
I uninstalled Set CPU and uninstalled Juice Defender. From my experience both hurt my battery life.
I never bothered to measure in airplane mode, because i use my phone to much.
My battery life improved dramatically during stand-by. 1% to 2% drop per hour with wifi on and a slightly bigger drop with wifi off.
I completely wiped the phone before installing EB and the used Titanium Backup to reinstall my apps without the data. I believe some of my previous battery life issues came from restoring data from certain apps.
I have the same phone/carrier. Do you leave 3G turned on? I feel it rapes my battery throughout the day. When I turned it off, it lasts pretty long.
Another problem I have though, is the drain when it is OFF. I went to bed with it at 90% juice and turned it off. I woke up 8 hours later, and it was at 65% when I turned it on. wtf. This only happens sometimes thou.. Other times it doesn't drop too much.

I experience the exact same issue. But for some reason my battery life is more or less the same with 3g off. So I feel like my phone is constantly searching for a different signal or something? I mean if airplane mode affects my battery life that drastically reducing consumption by like 9%/hour then there must be something up

Everyone who's been telling my phone is not sleeping is correct.
Only program is is that my phone's battery stats doesn't say which app is waking the phone? It lists Telephony as #1 with 1m 1s of awake time, and everything else is minuscule. There's gotta be something the phone isn't telling me :S Could it possibly be a hardware issue?
Or is there a better way I can narrow down this issue? I'm in the process of removing all apps.
Just curious, did you 'train' your battery?

Nope, but it's Li-Ion and my impression was these do not need to be trained.
I just emptied it to complete 0 yesterday, and charged it to complete 100% then calibrated it. Today though it was still horrible battery life until I completely wiped and flashed MIUI 1.9.23 then Trinity kernel brand new. I'm installing apps 1 by 1 to see which one caused me so much darn grief :S
All batteries are Li-ion nowadays, but I still feel after 'training' my battery for a week, they last substantially longer than new ones, fresh out the plastic.

Yes, battery drain is fixed. Also, I was on a completely different baseband for some reason, I was on the o2x baseband, fixed that JUST now, I think that was a part of the reason I was draining my battery like instantly. It was probably looking for a GSM signal!
Thank you for all your help

Yeah I set it to WCDMA Only. Battery life has been awesome lately.
Hey all,
About three weeks ago I had a strange problem. I noticed that in two straight charge cycles, my battery life plummeted from about 80% to zero in just a few hours. I'm not sure what the issue was. I hadn't changed settings, installed new apps, etc. My first screenshot shows an example of what happened. 4G and data were off during the entire time.
Since then, things have been okay. I typically get 3 days standby with 4G on and light use, or 4 days with 4G off. That's mostly standby with maybe an hour or so of talking and minimal use.
After those strange battery plummets, I installed and used GSam Battery Monitor to get more details about what processes were running on my phone in case I noticed the sharp drop happening again. Everything had been fine for over two weeks, with me getting expected battery life before this issue and not experiencing any odd, sudden drops (maybe 5 or 6 charge cycles). This lends me to conclude that my battery's charge capacity is okay, and calibration also shouldn't be an issue.
However, the problem arose once again a couple days ago. Went from 75% to nothing in just a few hours. 4G was off during that time. The third and fourth screenshots show the same issue. Charged my phone, and this morning the same thing happened yet again. At about 90% the plummet began, and within an hour or so I was at 75%. At this point I took screenshots of Android's battery status, and I also did the same for GSam to show what apps and processes were running. The phone's temperature seemed fine.
The GSam screenshots taken when the phone was at 75% and dropping are in the next post, since I'm limited to four images in this one. I have no idea what's causing this massive, sudden battery drain. The only thing I can think of is that I've done Verizon's OTA updates, but otherwise pretty much all my settings, apps, and usage are the same. Plus, for two weeks I had normal battery behavior, so I'm completely baffled.
I also know that cell standby is incorrectly reported in the GS3 battery screen, and I'm getting a good signal where I live so that shouldn't be a problem. I forgot to get screen time for the first case (first two images), but it shouldn't be more than 10-15 min there since most of the charge was lost due to the freak plummet.
If anyone may have an idea of what's going on, or if there are some tools/tests I may use to figure this out, I'd really appreciate it. I turned off my phone after taking the screenshots at 75%, so if I need to turn it on and check something for you I can probably do that. Thanks a lot.
FYI, here are GSam screenshots from when the battery was in the process of plummeting this morning.
i think you built in battery status settings are off. i barely get 12 hrs with medium use, so what i think it happens is that the battery monitor is not showing the proper discharge, and then all of a sudden it catches up to the discharge rate.
are you on stock rom, rooted, unlocked bootloader?

I am stock rom. No rooting, no unlocking.
These plunges are definitely an anomaly. Truly, with me barely using the phone and turning off mobile data, I get a few days of standby. I've had the phone since July, and the aberration in battery behavior has been the steep plunges I've shown.
In between these instance of steep plunges, I've had normal use. I really don't think it's an issue of calibration. Please believe me when I say that my normal, light use during the past four months gets me anywhere from 3-5 days with me barely using the phone. When I say barely using it, I mean not even touching it for an entire day if nobody calls me. But now, a sudden plunge in battery life is happening at 80% with no apparent reason.
I think it might be some kind of software or hardware glitch, but it's impossible for this to be normal given the battery life I typically get. Just looking at that steep drop, it's crazy and just happens out of nowhere.
But please trust me when I say that these sudden plunges that have happened a total of 4 or 5 times, causing the battery to drain completely in a few hours when I'm not touching it, are quite a drastic aberration from the normal standby life I get. Something is definitely wrong here, I just don't know what.
And one more thing to add is that after this sudden plunge and rapid drain, charging the battery still takes the normal time it does when I'm not having this issue. That is, about 2.5-3 hours to reach a full charge (and I charge with the phone 'off'). The battery is being completely drained. But this happened twice, then didn't happen for maybe 5-6 charge cycles, then happened again twice.
Before the first instance, I remember an OTA Verizon update around 10/5. My phone was okay for 2-3 charge cycles after that. Then two rapid drains. Then 5-6 normal cycles. Then two more rapid drains. There was a second Verizon OTA update somewhere in there but I can't remember.
and you said it only started once you did the OTA update from verizon right? well you could either try to go back to the stock verizon rom pre-update and see what happens there, or contact verizon and let them know what happens with the new OTA update. they could replace your phone, or it could be a bug of the new OTA update. i am on stock rom and rooted and deleted the apk that kept on trying to push the update. just unlocked by bootloader and so far my battery life has improved compared to previous locked bootloader.
i would take it to a verizon store and show them. They might give you a new battery.
I may have to do that. I'm just not really sure what the issue is.
- The battery can still hold a full charge.
- Based on running services, nothing is causing high CPU usage.
- The sudden plummet almost seems kind of random.
- Since there have been normal charge cycles, it's not an issue of calibration.
I'm not sure if this is a hardware issue or software issue. I'm trying to wrap my brain around what could cause the battery to drain so suddenly and sharply. Could the charge somehow be "leaking"? But in that case I'd expect it to happen all the time. If there's an underlying software issue, is there any other tool I might be able to use to figure it out?

Not from what I can tell. Note that the first couple plummet drains were overnight.
But today I caught it before noon. The phone wasn't hot, and the GSam screenshots show no CPU stress.
Maybe you can do a factory reset and se if that helps. They will probably do one if you bring it to verizon anyways. It sure sound like a hardware problem. You'd think if the processors are working that hard that the phone would get hot, I know mine gets pretty hot sometimes under heavy use.
Sent from my SCH-I535 using xda app-developers app
Thing is, all indications show the CPU isn't working hard, and the phone wasn't hot.
I'm stumped.
This is a noobish question, but I presume the only way to go back to stock is to factory reset? One thing I might wait for is the Jelly Bean update, presuming this random drain holds off until then.
But yea, I dread going into VZW because they're just going to try to pass this off onto me doing something wrong, or me not knowing how to calibrate the battery, etc. The information I've provided in my OP and in the screenshots would fly over their heads. Maybe I can just do an online chat and tell VZ to send me another battery?
The only other thing I can think of is that sometime before these plummets happened, I went online to MyVerizon and turned off the Backup Assistant for movies/music/etc. so I wouldn't get all those notifications. I don't think this could be the issue, since the plummet happens when data is off. Plus, GSam would show that Backup Assistant is hogging the CPU or forcing a signal.
I doubt swapping batteries will fix it, though. I'm thinking my internal hardware might have a serious problem.

Before the update, was everything normal?
Is the update with the HE base/baseband?
It probably isn't a hardware problem, just a bad base.
I've noticed after updating my GS3 to the HE base and the battery life was just horrid.
It's said that the new HE baseband uses up more battery also

I turned on the phone and within 10 min or so the battery life went down by 2-3% without me doing anything. As a test I've put it into Airplane mode, and it's decreased by about 2% in 45 min.
Now I'm wondering if I have a faulty antenna or something.
Yup ive had it drain 90% overnight many times for no reason. Called verizon and my new battery should be here today.

HE is the baseband version and the build number. For example I have: Android Version: 4.0.4
Baseband: I535VRLG7
Build: IM76D.I535VRALG7
which is the version before the update.
Like everybody else said, call Verizon or go to a store and let them know about the battery issues and they should send you a new one. Or even call Samsung and tell them you bought an S3 through Verizon and you are having battery hardware issues.

Hi folks,
since some days my battery drives me crazy...
Last week i flashed CM10 by nk111. Nice ROM, but my battery lasted only for some hours with normal usage. So I went back to MIUI...problem stayed.
Yesterday I flashed Jellytime and replaced the battery. The problem stayed as well. At 6 pm battery was full, I restored my apps with Titanium, used it a bit and when I was going to bed at 10 p.m. battery was 81%. Getting up at 5:30 this morning --> battery was 41%.
After the battery was full yesterday night I used display for maybe 10 minutes, why there are 36% battery usage by th display?
WTF happened to my system by flashing CM10 by nk111???
Any help is appreciated!
PS:
Baseband-Version: 20.72.30.0833U_3831.17.00.310
Kernel-Version: 3.0.50-g6ea80e4
First, do you have Google now on. It really drains the battery. If that doesn't help install better battery stats and let it go through a couple of cycles, it will help you pinpoint if any apps or wakelocks are draining your battery.

app called carat could also help you find the battery sucking thing. It's a bit more simple than battery stats, you'll like it if you're not an expert.
it doesn't need to be a new app that is sucking power, it could be the poorly made update of some app that you're using for a long time.
I installed both apps.
But in both I can't find any kind of statistics about consumed power by apps or something similar, am I that stupid?

I get max 24 hours battery life , sometimes 12 hours , so it's not something to worry. If you speak 2-3 hours and WiFi on another 2-3 hours that is the battery în my case 12 hours max.

IT IS something to worry, cause battery behaviour changed dramatically while I didn't change my usage of the phone.
40% battery loss over night should be a clear indication of abnormal behaviour.

you must run carot a day or two, than it will display some apps on the first page and the approximate battery life you get if you kill them. read the manual also..
Yesterday in the evening I realized a 96% entry in the Partial Wavelocks section - AndroidMediaScanner. I freezed it (I know where my pictures and music is located...), did a full load on the battery and for 4 hours the battery remained at 100%. I really thought the problem is solved...but in the morning...31%
But - the 'Media' entry in the android accu stats is gone, I think this is a partial success.
In the BBS app, there is no remarkable value - the biggest is 3,8%.
When I watch the graphs - WiFi and Awake is nearly completetly blue over the whole night (unfortunately, I can't take screenshots right now for any reason).
I'm a bit helpless right now, will charge the phone now and keep an eye on BBS the next hours/days.
androidmediascanner shouldn't be the bad guy, it's a system app that we all have. maybe your battery is the problem...

I inserted a new battery last week without any change. Don't think both batteries are broken.
The common way to solve this is to do a fresh install. Leave it for a day without any apps yo see if it is ROM related. See if the battery life improve. Install one app per day and monitor your phone awake period with screen on, it should be almost same.

Yesterday night I made a full wipe, installed Jellytime and Gapps and went to sleep...
In the morning --> 67%.
Very odd, normally this would probably indicating a defect battery, but it is new!
Maybe a hardware defect?
Maybe RRU Problem?
Hi,
I have a similar problem here. I was using the desire s for a long timne with stock rom (2.x android), a full battery was enough for ~2 days. Then I rooted the device and installed CM10 (NK111 alpha build).
2 things changed:
The battery is empty after 24h or less.
The wireless network is worse than before. This is my subjective impression but there are places at home or in the office where wifi worked before and stopped working.
I'm starting excessive tests (disabling everything, removing apps, running carat) during xmas holidays to find the reason.
My guess what it might be: to root the device I did a downgrade, including a radio downgrade. Now I run baseband 20.23.30.0802U_38.02.01.11 which is known as "Saga Test RUU" and has the lowest version number of the RRUs listed in the forum. I did not found anything about this in the forum or with google but maybe this is the reason.
My average battery stats with normal use (whole day, used the phone a few minutes):
~30% Display
~25% Wifi
~17% Mobile Standby
~5% Android Os
For comparison, my Motorola Defy has in a similar scenario ~5% Wifi and ~3% Mobile Standby
Hi
I have a TF700T, unlocked, TWRP and CROMI 3.0.4.
My battery meter is acting weird. For example I recharged both my tab and the dock this afternoon. I unplugged them around 16:30. I've been using my tab for the last few hours (it's now past midnight), not all the time, but quite often. The meter on the tab is still showing 100%. The one for the dock is showing 94%. This is not the normal behavior of my tab and it's been doing that since I unlocked and installed TWRP and CROMI. Before, it would start to go down almost immediately, and would start recharging only at 70%, like it's supposed to.
Last time it stayed at 100% for a while and then started to drain very quickly, and then stabilized and started to act normally.
I'm trying to understand whatcould be the problem. Last time it got "stuck" like that I went to recovery and TWRP was also showing 100% power left. So it's not CROMI. But it's something... Anybody else with the same problem? Or anyone got a solution, an idea? Because I'm worried this will get worse...
Thanks
You could try clearing the battery stats. I think TWRP has the option to do it, not sure about CWM.
Ok thanks sdbags, I'll look into that...
Is there an ideal moment to do that? After a full recharge?
Usually you do 100% charge, clear stats, reboot let it get back to 100% and unplug but to be honest it probably doesn't really matter.
You'll know fairly soon if you still have the problem.
I just checked mine and it started with tablet battery until down to 89%, then dock battery kick in maintain the tablet battery around 89-90%.
The dock shouldn't recharge the tab unless it reaches 70% or lower. At least it's what it was doing before, and what's documented as normal behavior. Since my tab spends 99% of its time docked, I don't know how it would behave undocked...
Looks like it solved the problem for now. Thanks sbdags!

Well, unfortunately, it isn't solved. When I deleted batterystats.bin it went back to "normal" at first, the tab was fully charged and it started to go down almost immediatly after I unplugged it. But yesterday it died on me while the gauge was still showing a little bit less than 30%!!! I did a full charge last night, and it's back to its old tricks: stucked at 100% for the last 8 hours (overnight).
This is very annoying... Is there anything I can do to recalibrate the battery gauge?
And why is this happening? I didn't have this problem when locked with stock ROM and recovery... I'm not complaining, I just want to understand and maybe try to fix this! Thanks!

Could be a battery hardware issue? Sounds like it's not reporting its current and voltage correctly.
You need to get some battery monitoring apps on it so you can see what is really going on.

Any battery monitoring app you recommend? There are a few on Google Play... I have Battery Widget Reborn, it does some monitoring, but it doesn't provide a lot of information. I'm sure there is an "ultimate battery app" or something... Any suggestion will be greatly appreciated!

Try battery monitor widget. It does everything you need.

Ok, thanks... Will try that and report!
Ok... So I did some testing... My tab is shutting down (more like crashing) at 28% and showing 6561 mV. I then have to plug it in and wait for 5-8 minutes before it will allow me to boot it.
So I plugged it in... It reached 100% at 8169 mV... But then, it continued to charge. As of now, it is at 8296 and still going up as I'm writing this!!
This issue is the same as issue #2 in this thread:
http://forum.xda-developers.com/showthread.php?t=2090826
Now, I don't know, but it look suspicious to me that this problem started when I installed TWRP and CROMI. Could it be related, somehow??

What happens if you wipe the battery stats again?
The only other thing I can recommended is a total wipe, reflash Asus stock to redo the bootloader, TWRP and reflash CROMI. Others don't have this problem so it is something particularly to your setup.
All those posts you linked are pointing to the 4.2.1 update causing the issue. As we only have 4.1.1 I can't see any relationship unless Asus injected some 4.2.1 code into their latest update which seems unlikely.

I wiped the stats yesterday. Looks like it doesn't do much.
I'll go ahead and reflash stock...
Thanks!

I suggest you should do a full wipe and reflash cleanrom and kernel. This way you can eliminated all the possiblility with software and pin it on hardware.

I have the same problem with my battery meter, and just like with you, it started when my TF700T was almost exactly 4 months old. The batteries (dock and tablet) have to be close to drained. I've been using the tablet without batteries for many hours, both yesterday and today. But my tablet battery is showing 100% and the dock battery is at 95%. That has to be wrong.
I have GSam Battery Monitor Pro. It can only tell me about the tablet battery (it's blind to the dock battery). Yesterday when I looked at this, it was telling me that the screen used no power. I'm looking at it now and it says that screen is using 68.6% of the power - that's more like it. But it's weird that yesterday the number was zero. It tells me that the unit has only been unplugged for 5 seconds, and has been telling me that since I unplugged it yesterday. GSam usually saves history, but not in this case because it thinks the unit has only been running on battery power for 5 seconds.
I also have a battery widget that is dual-battery aware. It has a history chart, but it doesn't tell me much. It shows the tablet battery at a constant level of 100% with no dips, and the dock battery very slowly dropping from 100% to 95% over the last two days. This is just wrong.
What's been happening is that the tablet will suddenly shut down when I think it's charged, and then I can't turn it on. I didn't realize what was wrong until I discovered that if I plugged it in for a while, I could turn it on again. Obviously the battery is draining completely, but the meter is incorrect. Also, draining the battery completely then recharging to green (which I hope still means "complete charge") has done nothing to recalibrate the battery.
I'm afraid this is a hardware problem. I guess I need to contact Asus?
I'm also having problems with constant browser crashes - doesn't matter what browser it is, I've tried them all. In general, this tablet has been a huge and expensive disappointment.
Edit: I'm running ICS 4.0.3 stock, rooted but not unlocked. I don't want to upgrade to JB because I need the volume booster app. I've read that the volume problem is just as bad under JB but the volume booster apps don't work (nor do many other programs I use). There is nothing in JB I need. From what I've read, people running JB have all the same browser crash problems, battery meter problems, etc.

I feel your frustration, I have seen more and more people with this issue. Well, we could say that either software or hardware, (not every situation is the same), so usually I recommend to do a factory reset then reflash a full Asus firmware, if the issue stills existed, then we can assume it's hardware issue. At this point, we can give Asus tech support a call.

Thanks for your reply. Have you heard back from anyone who has done a factory reset and reflashed the Asus firmware? Has anyone reported the problem going away after that?
The other thing I'm worried about is that it's a hardware problem that Asus doesn't know how to fix because they don't yet know what's causing it. I can't recall anyone saying they've found a solution to this. I've only seen reports of the problem.
I have other serious problems with this tablet, too. It runs short of memory all the time, though this isn't supposed to happen on Androids. I often have to manually clear memory to view screenshots in the Play Store. And the browser is constantly stalling, freezing, and crashing - every browser. I've tried more than 5 of them. This is especially inconvenient for me, since I make heavy use of the browser on the tablet.
I keep thinking of that pressure-sensitive Samsung tablet I almost bought instead...
Rooted -- Calkulin's Stock "Battery Saver" ROM -- Xposed Framework -- a few mods from XBlast Tools running.
First off, a Root Explorer search for com.android.systemui returned nothing.
What is com.android.systemui? I don't think I saw this in my usage until a couple of days ago.
Why does 31 seconds of CPU and 1 second of keep awake = almost TRIPLE the battery use of 12 minutes of screen-on time?????

It's the actual System User Interface. So most likely a combination of the rom and xposed are causing this. Also, dirty flashes of ROMs can cause this.
If you installed a new xposed module and noticed a battery drain the uninstall that module. Otherwise remove other xposed modules. You could always try a frew full wipe in recovery as well.
I have had this issue with mostly with dirty flashing which is my queue to do a clean flash. It's also possible if you restored any apps with data, like from Titanium Backup, could potentially cause this as well.

you got caught up in a lie, with buzzwords that are pushing for you to use the rom. theres no such thing as a battery saving rom. all those scripts/mods being used in the rom are just buzzwords. battery life is all dependent on how you personally use your device, how you set up your device, and your data/phone signal quality. a rom will not save you battery.
Thanks for the help, Tom. A visit to recovery to wipe caches and fix permissions and a reboot caused this -->
simms -- I do understand that. I am not really disappointed in my battery life -- and it doesn't seem to have changed much in the week that I've had the phone. But the reporting of it had, and that sort of alarmed me...

wow, your android system is high, even though only 10% battery was used. a reboot might fix that though. you might have to go through your settings and setup again, disable stuff like google location reporting/history(it wont disable your location).

I'm beginning to think the issue I'm having is in the reporting -- not actually a battery use problem. I've only had the phone a week, so my data base is small, but I haven't really seen bad battery life nor any real change in it. Even with some use and a bunch of time fiddling with the mods and stuff, I've yet to go to bed with less than 50% left. Mostly, more...
Here's the latest pics. com.android.systemui is back on top in the overview with 36% The detail page shows 39% and a whole 2 seconds of CPU. That just CAN'T be right...

Can u show the battery graph? And also why is your bluetooth on every time.

Which battery graph? You mean the current usage graph I showed in the OP, from Battery Monitor Widget?
Re Bluetooth: I just leave it on, so when I step in the car it just connects to the car. No muss, no fuss, no bother.
I suppose I could try turning it off and see how much battery I save. I know with my previous phone (EVO4G) the point at which I started leaving the bluetooth on all the time didn't change my battery life to any noticeable extent.
Here's battery monitor widget current use. The EVO idled at 70 - 95 ma. This one does seem to draw a lot more at idle. I don't know what's "normal."

Not very interesting. It keeps resetting, every time I plug in to USB to transfer the screenshots to my mac for posting here. I'm not leaving it plugged in very long -- I just move the pics and unplug it. I unplugged it this morning at 7:30 AM. It's now almost seven hours later and I'm at 93%. That ain't bad. It's a gradual descent -- no big drops like the one in your post.

Mine stats those are from my nexus 7 2013, Sot of around 4 and still 55% battery left.
I just showed u for sample. A simple restart should fix as simms told
I m on stock rom with x blast tool never happened with me....u can try to use ur phone in safe mode and see...I know its a system app but u can give a try with bluetooth off. Or flash a diff rom and see
If your phone is vibrating a lot and you have extra UI elements installed this seems normal.
When you only use a small percentage of the full battery smaller drains appear large.
Bit off topic, but have you thought of using WiFi to move your files over? No messing with the wire and you could even automate the task.
