how old is the battery?
did you overclock?
check if it's warm or even hot

the battery and the mobile are about 2 year ...
and no i didn't overclock the phone
and it gets a slightly warm in fact

battery life is approx. 1000 cycles, so in 2 years it is quite possible.
If you can swap battery and test. If you don't OC, then it's not a security restart.
I bet it's battery

i thought at the first it would be some kind of software problem ...
i'll try to get another battery and try it out
really appreciate your answer
thanks :good:

Weird coincidence. This started happening to me on May 10th. My 2.5 yr old phone would restart over and over even when plugged into the computer. I did a hard reset and it still didn't help.
I replaced the battery and it fixed it!

Problem Solved
it was really the battery
once i changed it every thing went back to normal .
thanks everyone for your answers :good:

Its also another weird coincidence as this issue has happened to me, my note 2 is also 2.5 years old and my phone kept restarting too, but i really didnt care much and instead, i continued to use it over and over and overclocked it to 1800 mhz and i have no idea how but is stopped restarting. It was weird, at least is saved me money buy not having to buy a new battery. But as i expected, a new problem arises, systemui keeps crashing. But the battery is still fine, all i did was flashed a new rom.

Battery serious problem

hey guys,i have been flashingmany roms every week for about 2 months, then I decided to start fresh.
wiped every thing via cwm and then flashed stock rom via odin,then rooted it.
problem is battery is as fast as HELL , and i have sudden drops, e.g. phone shuts down suddenly at 30% or even 50% , and when i connect charger it shows 0%.
tried battery calibration but no good.
I bought a new battery , and my phone still have sudden shutdowns when used for more than 30 minutes.
even offline.
Is my phone damaged ,or it has permanent leak ,even i change batteries?!
plz reply ASAP , and btw i dont have a screenshot cuz i am using stock 2.3.6.
I recommend you to go to a Samsung Costumer Service and ask for help. I think is a hardware issue, not a software issue.
Also, to use screenshot on GB, use Volume down + Home button.

Must be hardware. If the battery change doesn't quite cut it, then its a hardware problem.

Ok so i hope it ll solved on the next one
I use my phone only as a simple phone to make and receive occasional calls, with very occasional use of Google Search and Google Maps. It uses ~13% of remaining battery in a 24 hour period. I get 5 to 7 days out of a full charge. Right now mine is at 41% and i am in day 5. I expect it to be at ~36% tomorrow morning, beginning day 6. At the end of that day or beginning of next, at a bit more than 20%, i'll charge it again.
I would not expect to use the phone with the battery at anything less than 20%. I have it for emergencies, and i would not trust it at that level.

Samsung galaxy S4 mini battery drain!

Hi everybody...I have this phone and I have a problem.When I charge the phone up to 100% battery and then take it from the charger,battery drops to 99 or less without phone usage...And when I go to sleep and then wake up,the phone lost about 10-15 percent...Can somebody plesase help me?
Check what's keeping your phone awake during idle, "wakelock detector" and "better battery stats". Though you need root for these. You've nor given us any details of what your phone is and what ROM?? Try searching for threads on how to calibrate your phone battery.
Ohh sorry...My phone is S4 mini GT-I9195 LTE....I have stock android 4.4.2 kitkat...I have already calibrated battery and bought new battery...But same problem...
Will be an app causing your phone to wake
I dont know...i searched on the web and someone said that stock kernel have some problems

Not always the case... Depends when and where your phone was made. Could be a faulty kernel or motherboard but it also could be an app or a setting on your phone or an unclean install. Have you always suffered this issue?
I got phone about 3 weeks ago...and the battery was very bad so i bought new one.I also tried CM 12.1 but the phone is heating in unnormal way but the battery there is better...
You have problems with motherboard. Go to service center to replace it on waranty.
Powered by CM12.1
But my phone isnt on waranty...i got it used haha....ahh nvm,i will live with that problem.thanks for help!
Bad luck then. Normal consumption for our device is 0.2 - 0.3 % per hour in stand by.
Powered by CM12.1
How long does yours battery last with some normal usage?
Almost 3 days with moderate usage.
Powered by CM12.1
Woww thats a very big difference haha.

Your best bet seeing as unless you pay for a new motherboard is to try one of the battery drain fix kernels on here. Though I think you may be limited to certain compatible ROMs.
Why are you not staying on cm 12.1? For me it's amazing, i observed at least 100% more battery efficiency than stock (4.2.2). I also observed the same problem with high temp too. But i think we can't have it all. When i play games and the outside temperature is about 35 celsius, i do not expect anything less, because this mobile is not designed for this android version. I think that's reasonable and i finally can use my mobile with a joyful way without having my mind always on the battery stats!
Sent from my GT-I9195 using XDA Free mobile app
Thanks guys! And i will try CM 12.1 for longer time to see if anything will be better!

LG G4 Dual (818P) Battery & overheat

Hello,
i just bought my G4 Dual (818P) 3 days ago
when i first used it i don't think i charged the battery properly now it doesn't last too long
it drains a bit quick
Also it's overheating , just when i start using some apps it starts heating not even games or big apps
my phone is rooted btw
how can i fix it ?
i already tried factory reset & battery calibration and still the same
You have to recharge your phone some times, then it's (normally) getting better. If not, you have the same problem as I have... But just wait a week or two
did you get it fixed ?
Up ! anyone please ?
same for me. my 818P (indonesia) is getting HOT and often restarting. So I used kernel adiutor from play store, and disable 2 BIG procie, and set to powersave.

Horrible Battery Life on Nougat

So Just to announce where I am coming from, I am a Sony fan for the past 4 years, Had the Z2 and was totally blown away by the battery life it offered. Then I got the Z5P and even though the battery performance was nowhere near the Z2 I still got through an entire day with it without issues so I was happy.
Then came the Nougat update and all hell broke loose. I am literally getting just 6 hrs of battery life since the update. And even when it is idle it still drains battery like atleast 2 percent every hour.
Also the charging is very slow. I have a quick charger that used to take the battery life from 0 to 20 in atleast 10 - 15 mins. But now it actually drains the battery if I am using the phone while charging. And yes I have switched off the battery optimization option.
Any help will be appreciated even if it is just a confirmation that I am not the only one having this issue, which will at least let me know that it is not just my phone.
There must be some process with corrupted data after de update which is constantly executing something. I recommend you to do a full wipe, factory reset

Oh did not know this could happen. Will definitely try doing a full wipe and see how things go! Thanks a lot!
I never fully trust OTA updates, because it keeps all the applications data and some special case of your current configuration maybe is not "converted" to the new version and causes the programs to behave weird. Have you looked at the battery usage? Maybe you find the process which a huge % of battery eaten, and just wiping that app data is enough

Thanks for the reply! Yeah I looked at the battery usage stats and no specific app is draining more than 2 percent of the battery over a charge. The only things that have taken most out of the battery are 1. The Screen On Time which is to expected and 2. The Idle Phone which takes around 15% consistently in every charge.

after updating to .372 , i learned from internet that this build has battery draining issues. ( i never faced any )
after updating to .376. , the phone is as steady stable as my other xperias (btw z5p is my 6th xperia )
now there is however a catch.
1. if you updated on OTA , this means the update of 1.2gb via ota only replaced certain files from .305 to make it .372 build (android 6 to 7) --- such OTA updates USUALLY ends up having problems (in general) with battery draining issues. Such problems i personally faced during updating from honeycomb to ics. - in short whenever update is available; always install FRESH
2. if your bootloader is locked then use xperia companion to install fresh after wiping all data. (makebackups)
3. if your phone is not rooted then try disabling all un necessary apps under Apps section.
----
Trivia
You cannot compare Z5p with predecessors like Z3/Z2/Z1 and Z since
1. they were always smaller in screen size / resolution and were not 4k
2. They stops at Android 5 / 6 as their last builds and battery life was awesome w.r.t consumption

however some of friends on XDA agrees that .305 (android 6.0.1) (came out dec2016) is the BEST build ever for z5p. addressed all battery issues and it was the final build for z5p on android 6.0.1
even i am thinking to degrade my phone due to ram consumption of N is very high!
this is why xzp has 4gb ram!
I need to know. If I updated my phone to .376 and it's having this lack of battery life, DO I HAVE TO SELL IT OR DISPOSE OF IT BECAUSE IT'S LITERALLY A LOST CAUSE NOW? (P.S. I immediately did a factory reset after the Nougat install completed.)
Because apparently if you updated to this build, then returned to the last Marshmallow build, THE PROBLEM IS NOT FIXED, and reloading nougat will only make things worse. And if you updated to .378, it not only does this not get fixed, it breaks your headphone jack to boot.
Please help. I am freaking out about this battery life. I lost 60 PERCENT IN 6 HOURS OF BASICALLY PODCASTS. ?

Well, after all my trials I flashed MM back and everything is back to normal. The issue is with 7 so not sure what happened to your handset
EDIT: Re-upgraded once again= battery 8 hour life. Go into About Phone, Status and disable battery optimization. The handset reboots and incredibly this morning it was like the old days .

Maybe I'll try that. The best I was able to do was 21 hours with one bar LTE, 6 hour's sleep, and 3h40m screen on time with several hour's worth of Pocket Casts.
i confirm that on build .33 i lost my battery even on stamina mode one percent every 10 minuets over using wifi , it just keeps the battery when device is screen off -_- its horrible i didnt have this kind of problem with .253 and im wondering revert back to MM
