Hello all!
So I've owned the N4 since May 2013, it worked great, but right now some severe issues popped up. These issues include:
1) Sudden battery drops for no reason at all. The battery stats look horrible and nothing is draining the phone. See for yourself - added screenshot in the bottom of the post.
The battery drops often lead to a weird flat charge level. For instance, the battery immediately dropped for 20-30% (let's say, leading to a 50% charge), but that that 50% charge can remain for quite a while. Once it was like that even on 1%. Restarting the phone sometimes may bring the battery % up, but still the draining is unbelievable.
2) When the battery is below ~15% all hell breaks loose. I'm loosing the cell signal, sim pin requests pop. Basically, it's either charge the phone at this point or the phone will die in a couple of minutes. If you're using the phone with such low charge, the (what i assume) radio module restart will kill it soon.
Phone never been repaired, the screen is original. Also, the proximity sensor died (i guess) and I've had to flash xposed and install the "turn off prox sensor" module.
What I've already done:
1) Format cache
2) Factory reset
3) Clean flash stock ROM
4) Clean flash other ROMs (currently on Android M Chroma)
5) Flash older stock radio modules (thought it may prevent radio restarts)
6) Limiting my radio to only WCDMA mode (3G or nothing, instead of 2G/3G mode)
7) Replaced the battery few days ago (didn't help at all)
One more thing: my wife has the exact same phone, bought approx. same time ago. Bought from totally different places (one from Poland, second from Italy). Her phone has very similar symptoms, although, not to that extent. It means that her phone battery is also suddenly dropping and sometimes sim pin requests appear, but it's less frequent and not so bad as with my phone.
If you have any ideas how to pinpoint what's wrong or maybe even a solution - that'd be great. Thanks in a advance.

Probably time for a new battery as the phone has been used for almost 3 years.
It's a number seven in "what I've done" list it was my last resort to change the battery and that didn't help at all (immediately saw the same symptoms). That's why I'm clueless and wondering if the phone is basically dying...
Thanks for the reply though.
Are you sure the replacement battery is good?

Yeah, it's new and bought from the reliable store.
Try the new battery in your wife's phone?
That would require buying one more battery, because the original is so strongly glued to the case, that I will destroy it in the process of taking out (like I did with my own). So not really the best option to continue buying new batteries for allegedly fried phone
I understand. Maybe you need to apply more heat to loosen the adhesive?
Any Luck ?

I am facing a similar issue, did you find any solution ?
Unfortunately not.
Battery replacement did not help. Also tried replacing charger port controller on the motherboard, but that did nothing as well.
Ended up buying new phone and selling this one for dirt cheap amount of money.
The same started happening to me a couple weeks ago.
I think it's time to change to nexus 5 (or similar)
Same is happening to me, the cheapest solution is to use a power bank as I'm not ready to leave my Nexus 4.

Hi all,
I've got a serious problem with my Hermes:
The Battery is drained very quickly and becomes very warm. According to acbPowerMeter with 3G OFF, WiFi OFF, Bluetooth OFF and no running programs its drawing somewhere between 350-400mA (!) in Standby mode . But now the strange thing: when i switch WiFi ON the current drops to about 80-130mA sometimes 40mA or less.

I already searched the forum but couldn't find any solution for this.
ROM: Pays ROM 2.15 GER
RADIO: 1.50.00.00
same thing with
ROM: HTC 3.54.257.2 GER
RADIO 1.47.00.10
Obviously you know you need to replace your battery immediately.
I'm willing to bet that you've configure your WiFi to search for a 'hidden' SSID (then you switched the power setting to 'performance', instead of the default power saver mode).
The Device and battery are brand new. (Its a replacement for another TyTN which had a defective camera and also drained the Battery very quickly).
WiFi is set to energy save mode and it isn't searching for hidden networks. The thing is when WiFi is OFF the device drains more current than with Active WiFi!
Sorry, unfortunately i can't find any useful information in there.
Sorry if this doesn't belong to this thread, but I have a similar problem:
After using WiFi and turning it off, my TyTN's battery starts getting very warm and drains very quickly. I turn it off, remove the battery for a few minutes, then put it back and power the device on, but in a few hours the battery heats up again and drains completely very soon. I have no idea what to do with this... Any advice?
No, ideas? Help would be much appreciated
I noticed that sometimes my TyTN is working nearly normal, that means it draws 15-20mA with WLAN OFF, i switch WLAN to ON: 150mA, but then when i switch WLAN OFF it starts drawing 350-400 or more again
V87, please post the link to the tool you are using to measure how much power is being drawn from the battery. I want to make comparisons with my unit, just to be sure before I respond
http://www.acbpocketsoft.com/Products/acbPowerMeter/acbPowerMeter-Overview-2.html
It came together with my rom (pays 2.15)
Hey all,
I've been lurking for a while, just picked up a 8525, and noticed some of the same issues. Occasionally, I'll notice the battery getting warm, and after popping up acb power meter, the device is drawing 350-400ma. Turn on wifi, back down to 40-70ma. Wifi off, back up to enormous drain.
I'll shut the device off (long press power button), remove the battery, wait about 5-10 minutes to let everything cool off. Install device, power up, all good.
It's an intermittent issue, and I haven't been able to nail down what triggers the power draw. I'm still experimenting, and will post if I am able to notice any consistency in triggering the issue.
Hey, count me in with that same issue to. I thought it was a battery/charger problem after only getting about an hour out of a batter, but after a new battery and charger, I tried the battery meter program I saw that it was drawing 350-400mA while doing nothing and getting quite warm, but if I enable wireless it drops to 80-90mA. If there was something in that manual that is no longer posted. I would greatly appreciate knowing it.
Unfortunately no. the service manual that was posted includes a procedure for checking the battery voltage with a multi-meter and a test procedure for the logic board that can't be done without service equipment.
I have since sent my TyTN to be serviced for the battery drain issue, and am waiting to get it returned.
I had a similar issue to this. Got my Vario II, charged it up overnight. Next day took it off charge and headed for work. Got to work about 45 minutes later and the phone felt really hot in my pocket. Battery was down to 10%. Same thing occurred over next 2 days so I sent it back, got a replacement and all was good.
After playing with this unit, I've noticed that the high-drain/hot battery starts happening after using a program that consumes high CPU (AOE, flashing, etc). After powering down and removing the battery for a few minutes, and allowing everything to cool down, everything appears ok.
This could be exacerbated by loading the system while charging.
Any EE's with ideas?
Well my TyTN's back from the shop. They replaced the logic board. Hopefully this one won't have any issues
Maybe this was caused by an active 3G connection. I am currently streaming audio over 3G and the power drain goes up to 550mA. The battery becomes very warm as well, which is normal for 3G usage afaik. If you enable wifi, maybe the 3G connection stops and tries to switch to wifi, causing a considerable drop in power drain.
I also noticed that a soft-reset helps bring battery drain down as well. As if windows or the device keeps using power for some background process or something. Not sure if that if a software or hardware related problem tho.
First i hope u understand me.!! (My english is not that good....)
My phone was suffering from the same thing (for 3 months more less)...
It was really annoying because my phone started tu shutdown after 1-3 minutes of use. but yesterday i found that it was working as intended after i have formated my sd card..
I have been making some researches about this problem and i found that the problem may be your sd card.
I suggest u to format it in slow mode.
Restore device defaults

for me is working, im using FXP30 with doomkernel + wifi modules
I hope this work for u too, this bug is really annoying....
edit1 - try playing a game for at least 15-20 minutes in order to know if this worked for u.
let me know if this worked......
hm, my phone shuts down randomly after about 3 hours of usage. i'll give this a try when i get back home.
Hmm, the shutdown issue could be caused by using custom ROM or custom kernel but not usually caused by SDCARD.Maybe it is bug of your ROM. Have you try another ROM and it is the same?
Sent from Sony Ericsson Xperia X10 - Stock Android 2.3.3 Modded
is the same ..
edit - is only a temporary fix, after a manual reboot it start to shutdown again... at least for me.
Same problem here with my x10 w/ stock clock interactiveX, and class 4 sdhc on any kernel or rom. My wifes x10 is perfect with class 2 sdhc, doomkernel, interactiveX, unlocked sim and BL, OC'd to 1.22ghz (temp control using setcpu profiles). my problematic x10 is similar spec to wifes but with fat batt, and aftermarket sd card.
I slow formatted twice, still same prob, so replaced sd card, but still restarts. especially when using youtube, heavy internet, gaming, and general use while charging. SO, after observations, i suspect: 1 fat mugen battery is trapping heat under it, 2 bad sectors in RAM, 3 general hardware fatigue, 4 another sd card with bad sectors. since those are as common denominators during heavy use and caching...
I'm gonna go back to stock batt, and try another sd. if problem persists, its gonna be an excuse fo either a sgs2 or nexusprime
The device does shutdown itself if:
Temperature of the battery exceeds somewhere around 42-45 degree Celsius (or 107-113 farenheit)
and/or:
Voltage of the battery drops below 3.0 volts (Or what is set as 0% battery capacity for android devices)
Some third party batteries can show a charge level above 3 volts (above 0%), yet be "out of juice". It's known to those batteries that claims themselves to have more capacity compared to the original batteries. In fact, they don't. They only got the voltage "skewed up" in order to appear as a higher capacity battery.
(Most common among "higher capacity" batteries that have the same size as the original.)
My phone shuts down when the battery gets empty
My phone has been shutting of due to battery drain latley, ill be around 30 or 40% leave it sit, then when i come back ill hear it vibrate, hit the unlock button just in time to see the battery indicator at 1%, the trick is when i power back up the phone is back at 30 or 40% battery life again, i've calibrated, wiped stats but it keeps doing it.
I am in discussions with 3 UK and they have informed me that the issue, at least in my case, is down to me dropping the phone. I have told them that is the case, but they have insisted that a cracked glue joint is to blame. How many people have actually suffered from this fault, and what networks are you on?
What does the SDCard has to do with anything? The system is not even in the SD card.

Hey..
Did you ever Google "x10 random reboots "?
You will be surprised, but not the nice kind of way.
They say that it's a problem of the Mainboard so only Sony can fix this.
I have the same problem but not that often and only while playing games.
Greetings!
Sent from my X10i using XDA
Get a new battery
I used to have problems with my X10 (SO-01b) suddenly shutting down.
Typically the cause (from what i've read on XDA) is:
1.) It gets too hot
2.) need to recalibrate your battery stats
3.) you need a new battery
I spent a couple months testing out different things and found my battery's voltage would drop too low even when it had enough "charge"
The solution was to just buy a new battery; The new battery cost was really cheap from my carrier (about the cost of 3 to 4 starbucks coffees)
X10 launched over 2 years now; If you haven't replaced your battery by now, you're probably overdue for it (or get a new phone)
Fixed
I reformatted hubby's sd card 4 times in a row now no reboot issue. Thanks for all the great info!

I am suffering from this to. I will try a new battery. With me, the phone dropped a few times (battery cover is even cracked...). It is 2j+ old so it could well be the battery.
I have been experiencing this problem the past weeks, maybe months. The phone won't fully charge and usually stay at a value around 80 - 85%. Sometimes, it even reports to be 100%,and at the moment you unplug it from the wall, it drops to these values. Sometimes, however, it does charge to a full value, but anyway, the battery life is horrible.
Here you have a screens hot of the battery stats.

The rom I use is cyanogenmod 11. I always have been using this rom, since the moment I purchased the phone.
Like three months ago, my phone dropped to the floor and broke the screen. My home insurance company replaced the screen, so I think, even the phone is a year and three months more or less, I can't call LG for a replacement, can I?
I'm a bit worried because I'm making a long three week trip in some weeks, and I need to have a working phone.
I don't know if going with battery replacement, if try to flash stock and see how it behaves or what to do.
BTW. just for testing if it was the rom or not, I left the phone charging while switched off and got the same results. The original wall charger has the same results as if I charge it with a Samsung charger.
Thanks
I have the exact same problem, I posted about it a couple of days ago.
I have already replaced my battery once, that was almost six months ago, and now, I'm facing the same problem again.
I'm not sure if is only a battery issue, because this is my second battery with the same problem.
There is an app called batterie calibration by néma. I dont want to give up on your batterie/phone, so at least try this app out
I had the same problem with my old phone. What I would do was let the battery run down to 0% and let it switch off. Then i would charge it to 100% and it would work. Its only a temporary solution though as the battery would soon stop charging above a certain percentage after a few days.
I did change the battery on it but i experienced the same problem,it may be that the new battery was also faulty (if it was the battery's fault in the first place). What I did notice though was that when it did not charge above 80 or 85%, when the battery came to about 20% it would stay on 20% longer to compensate for the "lost" percentages. In essence it does charge to 100% it just doesn't show that on that battery bar.
Maybe give this a shot, it might work well for this phone. No harm in trying. You could also try reinstalling the ROM or returning to stock. For me on my old phone returning to stock did the trick.
same problem
i have exactly the same problem,'ive changed two batteries but there's still this problem.
give me a solution please!! i tried different roms, and flashed factory images of android 4.3 nd 4.4.4
It seems to be a common problem with this phone - not charging to its full potential. The other issue I have experienced - the phone goes dead for no reason. After trying a number of time trying to get it to turn on, it eventually does. I am waiting for the day that it actually does just die and I can purchase a more reliable phone.

Something wrong with your phone. There is no such common issue. I've been using this phone since last 4.5 years.
Instead of waiting for it to die, is it not good go ahead and get a new phone?

Hi,
I updated my Moto G4 to Nougat last week. Everything was fine. Yesterday there was some 114 mb ota update. I downloaded it and since then I am facing two issues-
1. Whenever I lock the screen using the power/lock button on the side, the screens becomes black and white for a millisecond and then it gets locked. I haven't seen any other phone's screen becoming black and white for a tad and then lock. Is everyone experiencing the same?
2. The battery is draining just way too fast. 40% depletion since morning. I only used the phone to make two 4 minutes phonecalls. I did not install any new app or game. Any troubleshooting for this?
This is the build number etc.-

Though it's unrelated to this update, when I first got this phone last year I had the same problem with the battery. What fixed it was manually recalibrating the battery. If i remember the steps correctly it was something like: Let phone fully discharge, plug it in and charge it with the power off for about 8 hours, power it on and keep it on the charger for at least another hour.
I updated my phone to Nougat yesterday and manually updated to the same update you're on. I haven't noticed that black and white issue with the lock screen and, if anything, the battery life seems better than on marshmallow. Hopefully battery recalibration helps out. A factory reset may not be a bad idea as well, especially if it wouldn't be a big inconvenience.

The phone charges fully in under 2 hours, thanks to turbo charging. Don't you think 8 hours are way too much? The black and white issue is being faced by other users too-

No. The whole point is that the battery percentage is inaccurate. Here's a guide for you:
https://forum.xda-developers.com/android/general/guide-how-to-callibrate-battery-device-t3308554
When I followed this process I let it charge overnight before turning it back on. I also didn't use the turbo charging charger that came with it, but instead a 5 port Anker usb charger. Perhaps I wasted time, but it worked.

I bought this phone last year in july and everything was going pretty smoothly until the nougat update. It completely broke my phone.
MY PHONE GETS FULLY CHARGED IN 30-45 MINS(OBVIOUSLY A BUG).
BATTERY DRAIN IS TERRIBLE, FROM 100% TO 15-20 % IN MAXIMUM 1 HOUR.
PHONE GETS SHUT DOWN ALL OF A SUDDEN AND SHOWS WRONG BATTERY PERCENTAGE.
Now let me tell you all what I have tried to fix this and STILL TRYING. -_-
In January 2017 tried methods like factory reset, clear cache partition etc, nothing works.
Now this month I thought of going back to MM to fix the problem l, that too didn't work.( I downgraded using fastboot)
Again updated to nougat and rooted my phone for the first time, and tried some popular custom recovery. Result = No change what so ever.
Tried Elementalx kernel = No results.
Currently using the Lineage OS 14.1 latest version ( heard it's the most stable CM) = no change even after using some battery optimising apps like greenify.
Attaching battery info screenshot for reference.
If anyone found out any fix to this problem then please tell me. I feel like throwing this piece of **** in the garbage.
PS - while writing the question my battery drained almost 10%
Definitely battery or board problem. Go to service center.

There's always a chance if it's a hardware failure of the battery. It depends on the service center. You should give it a try.

Try this and let me know if it works for you kr not.
Gonna uodate the thread again if everything works out fine after testing a few more days.

What firmware do you have on your device? Do you have any apps besides the standard stock apps (e.g. Google apps) on your device? How strong is your signal?
You may wish to download Better Battery Stats (free version here: https://forum.xda-developers.com/showthread.php?t=1179809 ) or GSAM Battery Monitor to check if there's any apps or processes draining your battery.
Alternatively, as others have suggested, if there's no obvious draining apps, it could be a firmware issue (try a clean, complete firmware flash) or a battery issue.

You may wish to download Better Battery Stats (free version here: https://forum.xda-developers.com/showthread.php?t=1179809 ) or GSAM Battery Monitor to check if there's any apps or processes draining your battery.

1. What firmware do you have on your device? I have the original unrooted stock rom running Android 7.0 and just checked no update needed.
2. Do you have any apps besides the standard stock apps (e.g. Google apps) on your device? The G4 plus is showing i have 133 app installed and currently running Nova Launcher.
3. How strong is your signal? I am setting it at Airplane mode while turning wifi on just to listen to music and surf the web.
I will download the Better Battery Stats and GSAM Battery Monitor to monitor the battery performance.
Thanks for your reply.
A possible cause is that the connector between battery and motherboard is loose (so that the accu cannot give full power to the motherboard). To fix this, you need to open your phone with a t4 torx screwdriver and tweezers (look for the instruction videos on this on youtube). Disconnect and reconnect the battery cable connector to the motherboard and make sure it is well fixed.
In my case this worked like a charm, I also noticed that next to the battery having normal behavior again, the phone was also much faster. Apparently the processor speed was also tuned down as the battery could not give full power before applying this fix. Saved me 25 / 70 / 230 euros (new battery / new battery with service costs / new phone)

Thanks a lot Rinthros for your solution. My Moto G4 Plus caused same issue after having overnight charging for two consecutive nights. 2nd day morning I realized that my phone discharged with normal use in only 1 hour. And after get fully charged in only 30 minutes. It felt very sad but then found this solution by Rinthros. I did exactly the same. Opened my phone with t4 for screwdriver and disconnected battery connectors and just reconnected it. It worked for me exactly smooth and amazing. Now after doing so from last 3 days my phone working as it was previously.
Thanks a lot for your solution Rinthros.
:fingers-crossed::good:
I too had the same problem but actually this occurs after updating it to Oreo my battery is not fully charging and after unplugging battery percent remains same got stuck after 1hr of usage device gets shutdown due to low battery all these problem are only in stock Oreo so I downgraded to marshmallow everything works fine after a battery calibration I dont know what was the problem on Oreo guys pls help me to fix it
Thanks a lot Rinthros. My battery was original from 2016 and tired. I decided to buy a new and followed an instruction on the net. After a day or two I noticed rapid drain and quick charge . In the end I had 30 min of use before I needed to charge again. I opened the unit and, for sure, the connection between battery and motherboard was loose. Fixed this and this was very successful. Two hours later, after re-charge, my Moto 4 is still on 94%. My theory is that a floor-drop caused the disconnect. I visited another forum in search for a solution, but nothing helped. I think this solution applies to other versions of Moto. Please Lenovo, listen to Rinthros, this can save you a lot of customers. Moto is a greate phone and deserves better support.
