My T-Mobile USA (standard ROM) Tp2 behaved very strangely earlier today, but seems to have recovered. Anyone had any similar experience?
a) Battery level decreased rapidly, and unit getting very warm
b) Battery Status today plugin showed > 900ma (and sometimes > 1300ma!!) current draw
c) Unit would not charge from my USB port (message that it wasn't providing enough current)
d) I put flight mode on, no appreciable change in behavior with all radios off.
e) Soft reset - no change
f) Task manager didn't show anything using undue amounts of CPU
In the end, I turned it off (completely), and it would then charge normally. Left it like that for two or three hours, and when I turned it back on everything seems to be ok.
I have a lot of software on there, but nothing installed new in the last few days. It's worked perfectly today - best cell phone or PDA I've had since my trusty Phillips Velo...
While this was happening it seemed slightly sluggish, but certainly not locked up. Only 'unusual' thing - yesterday I let the battery get real very low for the first time (left it with the screen on, and an app running). I almost wonder if somehow there's a power management issue recovering from this. Note - it was never completely dead, just very low.
Anyone had anything similar happen? I assume the problem is in the phone, not the battery (otherwise I wouldn't have seen the current draw)

you can try to hard reset and put everything back in...
what i usually do is turn off 3g because it consumes a lot of battery..i'd use wifi as much as possible or edge.
you can try using cleanRam to clean up some excess space on the phone.
not sure about the charge, you might need to restart your PC or reinstall active sync so it can detect the phone.

He's not talking about ActiveSync or not detecting his phone.
However, I notice this behaviour almost all the time (device runs out of battery within one night) but only see those large power consumptions sometimes.
My device cannot be seen by any PC I tried (after first installing Mobile Center) so maybe there's a flaw in some devices?

Yes -sorry I didn't make that clear. Phone was working ok (including activesync) - it's just that it was trying to take too much current from the USB port.
This has only happened once (fingers crossed!). I'm sure it's software (rather than a hardware fault), but I'm puzzled given that the task manager showed minimal CPU usage, and the power drain continued in airplane mode

Your reception is probably bad. The TP2 will basically go insane if the reception is bad enough, I've seen it drain a fully charged battery in under 3 hours if you have push data turned on and there's 0-1 bars of reception. The battery life is quite good when reception is at least a few bars but once it goes below a certain point I've definitely noticed that the phone goes insane and will get noticeably warm in the pocket and basically die within a few hours.
Turning off push data will get you slightly better battery life in this scenario but unfortunately I still found that the battery would still be dead by the time I needed to use it. And it's not a network issue either since I tested it on different networks and compared it to other smartphones dealing with the same terrible reception-this phone definitely uses an insane amount of power when reception is bad, which isn't a problem if you're just transiently going through a bad reception area (probably helps keep the signal from dropping) but if you're spending a few hours in a place with poor reception it will drain insanely quickly.
Thankfully I'm spending my time in places with better reception now-I basically ended up having to turn off the phone if I wanted it to still have power by the end of the day but now it's still nearly full at the end of the day with just moderate reception.
HTC should really change the phone's behavior when there's 0-1 bars-it's nice that it tries to find a network aggressively when it loses a signal but there should be a timeout on it where it should start checking at longer intervals if there's a long period of no signals unless someone's trying to make a call or something. Really useless when you put your phone down for 2 hours in some overly shielded building and when you pick it up to make a call and it's dead. Not to mention uncomfortable when it starts heating up like crazy.
I'm not sure why you still got battery drainage even in airplane mode though but maybe the phone had already gone into whatever insane mode it goes into when the reception gets bad. Maybe it's one of the apps running the background that freaked out as well? I think my battery life was still kinda bad in airplane mode as well, for some reason I had to literally turn the phone off to get it to stop killing the battery.
i get zero bars at work and no reception. i've noticed that at work, my phone gets destroyed and lags like crazy and barely usable. it gets no reception for 8 hrs so its nice to know that other ppl are experiencing this problem and its not just me.
my tilt did this today, was warm to the touch, idled' didn't use it all day 6 hrs idle with signal, battery drained to 50% made a phone call 13 min duration, put the phone down watched a 2 hr show, phone dead.
not from signal/data.
My Tilt2 stock rom appears to have done the exact same thing today. Yesterday it had low battery for the first time ever... then today, it completely died in my pocket while at work (usually I have about 80% battery left at the end of the day). I noticed early this morning that the phone dropped from 100% to 60% about 2 hrs after it was off the charger. The phone felt hot. No programs were running in the background either. When i saw this, i ran cleanram and it still died a few hours later. Reset the phone and charging it now, hopefully this was a one time thing?

I think this might be it. Reception at work is normally really good (there's a tower in our parking lot!) - but I noticed today they are working on it.
The strange thing is that putting it in flight mode did not stop the power drain - to me that just doesn't make sense. However, I'm thinking that when I first did a soft reset, it probably wasn't in flight mode. So, the complete manual power down, followed by the resulting soft-reset into airplane mode) might be what fixed it.
My phone is often in areas of poor coverage (NW CT) - pretty much every day to/from work, and I've not seen this behavior with the TP2 before. Other GSM phones I've had do noticeably use more phone in areas of poor/non existent coverage, but this was a relative melt-down - I did wonder whether I had an internal short.
It's been ok since, and I'll report any future incidents or findings...
Happened to me two times, I figgured the problem was the GPS connection, improper exit from GPS app (AmazeGPS). Can be related to GoogleMaps or other app too. After restart, everything went back to normal.

If that is so, how can we check if the GPS is still running?
I do a reset often, but that won't change a thing...
Besides, when I look, the power consumption often is 'slightly above normal' - 150maH-250maH.
btw: what is considered as normal consumption?
Battery Status plugin
I hate to sound like a fool, but I'm running the stock ATT Rom on my Tilt 2, and I cant find the "Battery Status today plugin" you mentioned. Is that a T-Mobile only thing?
Is there a .cab for it?
To reply to the primary topic though, I've experienced the heat increase/battery drain level thing, but it just started yesterday after I installed a whole bunch of stuff. This weekend I'm planning to hard-reset and load stuff slowly so maybe I can isolate the cause.
I'll post an update if I figure anything out.
FWIW - I've recently been trying to track down a battery drain, too.
For me, though, the drain has correlated with trying out SPB Mobile Shell 3, so that is clearly a likely candidate. However, the drain does seem to be mainly limited to night time.
For example, on Sunday the phone dropped to only around 80% after a full day out and about. However, by Monday morning it was down to 10%.
Similar results on Tuesday night - almost complete drain by the morning.
To see if I could work out what was going on, I installed acbTaskMan yesterday, and set it to log CPU overnight (it periodically logs CPU usage, power drain and the top three CPU users).
Unfortunately, there isn't any *obvious* candidate:
Microsoft "My Phone" kicked in for a couple of minutes and used quite a lot of power (max of 493ma). However, this dropped off once "My Phone" had done its stuff.
A lot of the time, its actually acbTaskMan which is the top user of CPU (probably unsurprising, given it is monitoring and logging).
There does seem to be a bit of residual network traffic - every five minutes (or so) there are a few UDP and TCP packets being sent.
Overall, the average reported power usage was about 113ma (with the max being 493 and the min being 5!). However, the reporting period seems a little odd - most of the time it reports every 5 seconds, but there are a few periods earlier in the night where there are gaps of up to 5 minutes.
What would people generally expect the average power usage to be when on standby?
FWIW The comments in this thread about low signal could certainly be relevant. I do have pretty low signal at home and I did leave the phone in a slightly different place last night (where it could have had a better signal than the two nights before).
My current hypothesis is that
Something in Mobile Shell is causing the network connection to keep alive all night (or is at least turning it on every five minutes).
This coupled with poor coverage in my house is hosing the battery. During the day, with good coverage, the network traffic isn't causing as much of a problem.

you might want to try this.
Under MyPhone, disable the Current Location.
Under HTC Settings->Location, disable all the location information.
See whether this helps?
Thanks - this is a good idea.
However, I think I may have uncovered a more fundamental (and dumb) cause. Somehow (probably user error, but I'd like to think some nefarious impact of installing the SPb stuff), my "peak" times for Activesync had been changed from 8am to 6:30pm, to 8pm to 6:30pm. This completely explains why my connection kicked in every 5 minutes overnight (as this is what my "peak" exchange sync is set to).
Having fixed that (!) I'll see whether my power usage is miraculously better tonight! If not, I'll give the location stuff a go too!
Ed
Checking mail all night is not a good idea!
Ahh yes - much better now. I went to bed at 80% battery and woke up at 70%.
The task manager log has logged far fewer points (only 300 logs over 7.5 hours, as opposed to the 5400 that I'd expect if it were logging every 5s), which I guess indicates that most of the night my phone was in "deep standby", or whatever one might call it.
FWIW I certainly recommend acbTaskMan as the logs it produces are very handy to spot what is going on for this kind of thing. For example, even in a low battery drain night I can spot exactly when various services are using the network (e.g. checking mail, Google Maps updating its latitude stuff, etc.)

I noticed somethin strange last night.
The battery was still for 63% full when I turned the device off (Yes, really turned it off!) and still next morning the battery was completely empty!
Now how is that possible? I do have two batteries, which do exactly the same, so I could test this with the other one, but this seems to be seriously wrong!
I had a similar problem with Sprint. after several trial errors, I traced the problem to the Verizon radio (2.23) I used after SIM unlocking. I went back to sprint 1.96 and voila. Since then now I have moved to Sprint 2.32WU and it works even better.
Another battery saver is this trick "disconnect network when idle for 1 min timeout":

Had same thing happen...new tilt (1 month old) got hot and drained battery in 3 hrs with no use! I believe its a GPS program such as googlemaps or Trapster that caused it. A soft reset and im golden. Hate having to soft reset all the time
see this often, almost always because gps is running and did not shutdown when the program using the gps was closed. Chartcross GPS test will show you if the gps is running or not and usually will allow you to exit, and stop the gps induced battery drain. I have gotten in the habit of doing soft reset after using tomtom or google maps, to ensure that GPS is off.
At least for at&t devices, gps is the culprit for huge battery drain, hot to the touch. I will add that little or no signal to the phone will do the same thing. When I am in marginal coverage area, I turn off 3G and that seems to stop the excessive drain and heat build up due to low signal strength.
Not straightforward, for sure and one has to pay attention to the device, or when you need it most, the battery is done.
Hey All,
I'm just wondering if anybody else is experiencing this issue. Since upgrading to Lollipop, my Nexus 7 battery loses FAR MORE battery while idle than when I was on KitKat. I was hoping that 5.0.1 would fix this issue, but I seem to be having the same problem. It's entirely unacceptable that I go to sleep with 31% battery, and wake up with the tablet DEAD. I have kept a close eye on Running Applications, and have made sure to close them all before leaving the tablet alone. So much for Project Volta...
Anybody else having a similar experience?
Thanks,
Collin
I'm actually seeing the opposite. On Saturday I had mine plugged in and charged to 100%. I took it off the charger and threw it in my bag, where it sat for about 7-8 hours (drove about 3-4 hours and then it was in my car for a few at a restaurant before bringing it into the hotel), wifi and bluetooth on, but disconnected the entire time. It is in a Poetic smart flip cover so screen was off the entire time.
When I got into the hotel it was still at 100%. Used it for a bit that evening, and again the next day before driving home, and finally used it some more at home, but still had over 50% left before bed.
My battery life is also suspect.

I was one of the Android L developer preview early adopters and the only thing that kept me from switching back to cyanogenmod was the fact that on the last developer preview whenever Flo said the battery was low I was so surprised I felt cheated. The battery life was so good every time it gave me low battery life notification I was shocked because I had forgotten that this thing even has a battery and needs to be charged.
I don't know if this is psychosomatic or what, but it sure doesn't feel like this on 5.0 or 5.01.
Full disclosure: it's reporting 6h 22m of screen on time with 5 hours of battery life left to go, but it sure doesn't feel that way.
The battery settings used to tell me ridiculous things like 6 days of charge left. It doesn't do that anymore.
Right now I'm in the process of discharging it all the way to death. We'll see if that makes a difference.

Yes I'm having this issue. After upgrading via ota my tablet is dead in less than two days from battery drain

@collin5022
OTA, OTA with factory reset or img flashing?
Because if you upgrade yours N7 via OTA without factory reset that (and various others) bugs are possible.
My N7 doesnt show idle battery drain (img flashed) or any other bug, so far im very satisfied with 5.0/5.0.1 android.
First off don't close applications this is not Microsoft windows, second use CPUspy and a wakelock detector to see what is preventing your tablet from deep sleeping, third use a system disable app like auto run manager to disable any services necessary, fourth.....profit
^Agreed except for the last part.
Those apps that stop/freeze other apps like the one you mentioned, greenify, anything like that are all bull**** that cause more problems than they claim to fix, IMO.
Flash the factory image. Don't take the ota or keep data when its a major new release.
Battery life is awesome on 5.0.1 never been better.
Android 5.0.1
Default OTA 5.0.1 brings NFC active! When i turned it off, the battery became significantly more durable!
Just try it!

If you disable the 3 common service locks keeping the device from sleeping there have been no problems so far for me on n5 or n7
And yes greenify is worthless autorun manager not so much
^Yeah I see what you're saying. But still I don't like interfering with system apps, well like play services I mean. That can cause problems and battery drain. It really depends on how you use the tablet.
Edit: And obviously like said don't be closing running/cached apps. This isn't Windows 98.

Well I fixed it by flashing the unofficial cyanogen mod build for the Nexus 7. Battery life back to 4 days like I'm used to, and no idle drain.

I have the same issue something is keeping mine from sleeping cause its always warm. I used to get 5 days now I only get 3.
Watch died mid-day today
Weird, my watch has been awesome...until today. Usually I can go 6 AM - 6 PM and still be 35-45%.
Today sometime around 2 PM I noticed the watch was dead. It won't even turn back on.
The funny thing is, another guy at work also has one, his did the same thing today!
And he usually gets 18 hrs + of battery life as well.
Anybody else experiencing sudden severe battery drain in the last couple days?
Same here.
From a few days ago, my moto 360 went from lasting all day, to lasting till about 3pm. I have changed nor installed nothing. I look at the watch about 10 times a day, I get notifications on the watch about 10 a day (facebook messages, skype messages etc), and get 1 or 2 calls a day (which makes it vibrate). This has not changed either.
So now the watch is useless, unless I carry a charger around with me.

It's happened to me once or twice, randomly. No idea why. Just happened the other day -- next day was perfectly fine.

My theory is that battery life tends to drain more when there is an update to Google play services, thus resulting in a mismatch between watch and phone versions of this app

I agree, battery life on my Shamu has been all over the board lately with play Services being the culprit.

I've had my Moto 360 2015 for about a week now and it usually gives me 2 days of battery life, but two days now it seems to be draining overnight, I go to sleep with it around 50% and wake up to have 15%.
It wasn't two nights in a row, so I'm thinking something is randomly running in the background (haven't installed any extra apps).
The only thing that occurred to me was that maybe the heart rate monitor keeps trying to run while the watch is flat on my night stand... does that make any sense?
Thanks

Possible, but not likely. On my first gen it can sit on my dresser and if I bump the dresser in the dark I'll see the heart sensor light up. Do you live by train tracks or something that shakes the place and would wake it up? ?

Past 3 days my watch has been taking a battery nose dive around 6 hours in... Life seems normal up till that point, and if I look at the battery life in the wear app, it shows it taking a dive. When that happens, usually I get less than an hour before it's dead. If I look at the apps which seem to be using battery, Message+ shows up using 30%. Not even sure how to disable that (or if I should). I now have to wait until I get home tonight to recharge and see if I can reset the watch...
Hey guys,
after dropping my beloved Nexus 4 to the concrete floor in May, I bought a new S4 mini in the electronic market because of it's decent size and all the fuzz about having a very good price-performance-ratio.
After a few weeks I already was fairly disappointed.
On an average work day (without WiFi) and little use (~30min OSD) the battery wouldn't last a full day. I tried the usual things like turning off GPS, bluetooth and using Wifi whenever possible (turning it off, when not in range), etc. I also used the App greenify which boosted my deepsleep in Wakelock Detector to stable 85+%.
When using GMaps/navigation my phone is getting hot (~50°C) and battery is drained within minutes. When trying to navigate out of the city (<15min navigation) one day my phone was discharged within 3 hours after a full charge. I got Wakelock Detector, Better Battery Stats and Battery Monitor Widget installed.
The only thing I found out, that when I am connected to Wifi the drain is a lot lower 1-2%/hour compared to when I am using 3G/H+ which results in 7-15%/hour (both when not using the phone), although there is no problem with signal quality. Recently my phone started to bottoming out rly hard when hitting the 20% mark. From there I can watch the battery dropping to 0% within a few minutes.
Things I tried so far:
- turning off features that are not in use (GPS, bluetooth, Wifi when not in range)
- make sure phone gets into deep sleep/greenify apps
- recalibrate akku
- reduce brightness & disable auto-brightness
Setup:
GT-I9195 bought in May 2015 from electronic market chain
CM 12.1 (Android 5.1.1, serranoltexx)
Standard CM Kernel
Baseband I9195XXUBML4
I can provide Screenshots from BMW, WD and BBS. Any ideas how to solve this or what else I could do?
Probably you should use something like better battery stats, to check
- if a service is going mad, then turn it off with disable service to test (most times happens with unclean flash)
- if you have an app with wakelocks
If you can't find anything that way, might be a hardware fault.
Personally if I came across this problem I would return the phone to stock Android and do some tests, see if the same happens again. CM12.1 can have issues across different same model phones. Try the Samsung Phone Info app to see how old your phone is. I'm guessing it was second hand? Some older revisions of the Mini had battery problems. Maybe a new battery is needed? Maybe.. As for the battery draining 20%-0% in minutes I have also suffered this on a brand new March 2015 device. Not all the time though it only happens with randomly once a week. But I put that down to the battery not been fully calibrated and then drained and recharged over the next 3 4 days, as I use a spare battery and swap out the batteries regularly which means my battery is very rarely calibrated.
All that said though I can easily get through an entire day if not 2. And using stock I'm able to get 4 and a half hours on average every time, maybe 4 hours of screen on time when using 3G a lot and GPS etc.

I have had the same problem as you.
I return twice my phone to vendor. But they could do anything.
I solved it with undervolting and underclocking my phone (only the low frequency).
I read from someone, you can undervolting 150 millivolt.
My experience, is undervolting 125 milivolt. and underclocking the low frequency at the minimum.
You didn't feel any difference, behalves that the phone is cooler and battery live is better.
My WiFi and Bluetooth are always on. I don't have to recharge my phone during the day.
It is so effective en transparent that I don't understand why Samsung didn't do it natively.
Hey,
I tried to apply some of your advice and flashed the newest stock rom for S4 Mini (Kitkat ...COE4).
In that process I recognized that the Baseband is not updated by CM and that the one that was installed when I bought it was fairly old (from 2013). Do you think that this might be part of the problem? (I sort of hate the Samsung Rom)
This week when working and not having Wifi all day, I managed to get 2h of SOT and still had around 25% left which I couldnt have gotten before imo. I only lose 1-4% per hour when the phone is not used. But still thats not pretty good, when ur saying you can get 4h with GPS and everything. I also didnt use GPS. And today when I restarted my phone it just went from 40-ish % to 15% without any reason. Any more ideas?
I installed BetterBatteryStats today and will try to give some more insight the next days. Wakelock detector said that I had 85% deep sleep (timeframe 1 day 2 hours).
Try the Samsung Phone Info app to see how old your phone is. I'm guessing it was second hand? Some older revisions of the Mini had battery problems. Maybe a new battery is needed?

No I bought it new from a electronic store (Media Markt). The app says that is was made on Oct 19th 2014 in Vietnam and that it is original/not refurbished.
How much do you gain by undervolting (SOT or % per hour when idle)?
How do you do it?
maybe the best way is to downgrade by flashing CM11 for example ...
(another way with stock + Alexax kernel + own debloat&freeze ... )
I have the same consumption problem with Resurection Remix LP too ..... very strange !
Lollipop is supposed to be less angry than Android 4.X.X ... but it seem have problem somewhere for our S4-mini sources maybe ,i don't know ...
This night I did some BBS tests:
Setup:
Stock Rom I previously installed (see posts above)
charged phone during evening
set up custom timepoint before I went to sleep
WLAN disabled
all apps greenyfied except those I deemed significant that they keep running (Whatsapp, calendar, Swiftkey, BBS, BMW, etc). Forgot newly installed app hoomn.
I had to upload the logfile to pastebin because it was too long for the xda forum: pastebin.ca/3256568 (I am not allowed to post URLs, sorry)
I lost 14% of battery during 9hrs (-1,6%/h). That's probably not too bad?
93% deep sleep, 33min awake time
Weird things I discovered/things I did not understand:
- negative Voltage loss?
- Wifi runtime 100% although I disabled it
- dominant wakelocks (count > 100, all of them < 30s): Alarm Manager, RILJ1, *net_scheduler*, GCM_CONN, ContextManagerWakeLock, Event Log Service, AlarmManager (com.sec.spp.push.Samsung Push Service), SyncLoopWakeLock, GCM_HB_ALARM
- dominant KWLs (count > 100): ril-fd (25min), bam_dmux_wakelock (13min), radio-interface (7min), PowerManagerService.WakeLocks (3min), mmc1_detect (1min), alarm_rtc, alarm, sec-charger-monitor, smdcntl0, pm8921_soc_lock, power-supply, KeyEvents, smsm_snapshot, qmuxd_port_wl_0, qmuxd_port_wl_1, smdcntl1, mmc0_detect
- Alarms (>20): ccc71.bmw (Battery Monitor Widget), android, com.google.android.gms, com.sec.spp.push
any ideas/assessments?
I have a 2 year old S4 Mini (GT19195), currently running latest stable CM 13.
The phone is working fine except for the occasional (once a week or 2) unexplained battery drain.
With my fairly light daily use, the battery is lasting over 2 days. <And can usually run 4 or more hours screen on.> However, in the last few months, at random times (even with phone asleep - screen off for > 10 min, so presumably in doze), the phone will heat up, and battery will drop 5-10% per minute. After the phone shuts off from dead battery, recharging and restarting the phone will return things to normal, until the next time.
During these episodes, the phone behaved normally, I did not notice any lag on waking up the phone, switching/opening apps, etc. The battery meter page showed no unusual process using the battery (none of the process actually showed any increase in % battery use); except for the battery life dropping off a cliff as I watch. <I noted that the battery usage stat never adds up to 100% even in normal use ... It might show 10% screen, 5% Android, etc, but all that only adds up to 50% or so from full charge to when the battery is near dead.>
Anyone seen this before? Is this a sign of an ailing battery, or something else? Can this be a software problem - like something running away in the background? <Of note is that this happened once when I had completely wiped the phone and had the fresh install of CM 13 + Gapps (micro) ... so if this is software, it would be something in stock Android, rather than a 3rd party app.>
Thanks for reading & responding.

This sounds like the processor is stuck on max frequency. Either it is an app(s) playing up or some other process that is keeping the CPU working when it should sleep.
The first thing I would do is install BetterBatteryStats app or something similar to see what is keeping the device awake. You could also try to grab a logcat, but you would need to catch the incident and either plug into a pc with adb or run an app like catlog

That sounds like an issue I've had for several months, also running CM13 (Official) nightlies & Open GApps micro, unfortunately I've never had the time investigate (well I did once but it worked fine, I couldn't recreate the problem). It is currently happening less than once a week so not a major issue for me.
I've noticed several times that the phone felt hot, I've then used the Trepn profiler app, it would show the web browser running at 30-50% cpu constantly, so stuck as per @noppy22, though not at 100%. I have tried all the major browsers and they have all done it at some point, also most have crashed at some point, which I suspect may be related. Normally just the browser app crashed but yesterday using Chrome the phone FC and rebooted itself. Crashes seem to happen when I touch screen or scroll (though one may not have been when touching). Also XDA app crashed (1st time) when scrolling a couple of weeks ago, so probably not just browser issue on some sites as I thought previously, but might be unrelated. The stock battery meter did not show particularly high battery usage by browsers, though were a little elevated in % terms but hard to tell due to different usage patterns and not checking when things are good! I have noticed a bit of lag, which now makes we run trepn, if it shows high than expected usage by an app I close the app, which fixes it even if I go back to the same web page. This morning I woke up and my phone was off, I put it in my night-time profile (wifi & data off) that normally only uses a few % overnight but last night it must have used more than 30% of battery that was left, first time this has happened.
The other thing to consider is how good is your battery? At 2yrs old it could be tired if it's had a hard life (though yours maybe not) or you have allowed it to get very hot eg I did one trip using gps nav with phone mounted in windscreen cradle driving direct into the Aussie sun when my battery was about 2.5yrs old, thinking back I now think this was when I first noticed my battery was really dropping of quickly when around ~40% charge (though it was faster with more charge remaining also than my new battery, I would say), so think I the high temp the phone got to that day affected the battery. I think 4hrs of screen on time may be marginal, I was only getting about 3 to 3.5 when my battery dropped off fast, my new battery is giving me 6hrs SOT (mostly using browser app), so possibly you just need a new battery as only one other user has reported high cpu usage like I have.
Battery stats not adding up to 100% is normal.
I've just installed BetterBatteryStats, so I'll give it a week of so and see if it catches anything. So far nothing unusual in the stats.
I am leaning towards this being a hardware issue, likely the battery. Since the phone responded fairly normally during the overheat & battery drain episodes, this does not seem to me an app taking over the CPU. If the CPU was occupied by an app, shouldn't everything else be slowed down?
I have so far noticed no particular pattern to these episodes, and I cannot reproduce it at will. It is infrequent enough for now that I can live with it (although an unexpected dead battery is annoying.) I will see if the monitoring app pick up anything.
Hey guys,
Maybe you have to try to flash your stock or custom kernel again.
Thats probably the problem.

When I got mine a few years ago the media process kept getting stuck and overheating/draining my phone and even a reboot wouldnt fix it. I found out because I was using the system panel app and monitoring cpu of system processes. I ditched and deleted the gallery app (it was trying to create thumbnails for 100+gb of photos and videos) for quick pic v.4.5.2 on every phone I've used ever since and haven't look back.
