[Q] Battery Drain on Arc, 2.3.4

Hi All
I know that there have been many threads on the battery drain issue but i wanted to see if we can get to the bottom of the problem. I have emailed SE support but they fob me off with the usual patronising answers.
Anyway I have an Arc, and i had flashed the firmware to 2.3.2 (3.0.A.2.181), and rooted it. Battery Life on this was fine, 1.5 to 2 days.
I have since flashed 2.3.3 (4.0.A.2.368), 2.3.4 (4.0.2.A.0.42) and 2.3.4 (4.0.2.A.0.58) With all of these firmwares my battery life is terrible, not lasting more than 12 hours, even if i put the phone in airplane mode during sleep. Using Battery Monitor, i see that with nothing running the phone is using at least 70mA. So obviously i tried to reflash back to 2.3.2, However doing so brought up the 0% issue. So i reluctantly went back to 2.3.4. I have also tried reflashing the baseband to 36, following http://forum.xda-developers.com/showthread.php?t=1382657. However no change to the rubbish battery life. I have used things like autostart to stop apps from automacally starting, turned off bravia engine, auto network search, turn down brightness and everything, but still the phone uses up 70mA. So what is using up all this power? Do i have a faulty phone and should take it to the a service centre to get it replaced? Or will a replacement phone with 2.3.4 still have the same problem? Does anyone know which of the "essential" running services is using up al this power? the phone is rooted using zergrush, but the bootloader is locked.
This battery issue is really making me think twice about gettin another Sony phone, which is a shame as i have had one for the last 7 or eight years now...
Many thanks

Is this battery behaviour normal on the later firmwares? Have I posted this in the wrong forum? Just want to know what my options are to try to fix this battery prob. My wife's sgs2 uses around 7mA during airplane mode! So the battery drain is really rubbish on the Arc!!!:-(

got the same problem, tried all the tips found in this forum, even doing battery calibration didn't help.. not sure if I'm doing something wrong.

[Q] why GT-N7100 constantly restarting?

Hello everyone,
My note II restates out of the blue without any good reasons :crying:
it generally happen when i play any game or use 2 or 3 apps at the same time ( like sound cloud , facebook and messenger )or ( game and messenger ) or playing for a long time ... knowing that the battery is fully charged or at least more then 80% ... it suddenly restarts with about 2 % .. and i take that battery out and in and open the phone to find it about 60%
i tried to factory reset
knowing that the phone on kitkat 4.4.2 the original french update from Samsung , and i tried also to run the secreat codes but neither of the code worked!!
can anyone please tell me what is the problem and how can i fix it please

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.

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!

Thanks guys! And i will try CM 12.1 for longer time to see if anything will be better!

LG g3 restart loop

I've had my g3 for 2.3 years, and it suddenly went into boot loop one day after charging the phone. The boot loops for around 3 or 4 times then stopped and stayed shut down, got it to repair shop yet they claimed that it wasn't hardware issue but software. I doubt that as I've updated my g3 to android 6.0 last October and has been working fine since. However, just to note that I was charging with a broken cable last time before it went into this boot loop. What's the problem with the phone and how can I retrieve my stuff as i haven't backed up yet. Is this problem fixable as I am trying to avoid factory reset and data wiping at all costs.

I had the same problem , it happend suddenly 2 days ago and i am trying to solve this stupid problem but so far no solution.
I upgrade it to 6.0 then downgrade 5.0 tried different versions but no solution.
Wierd thing is just started from nowhere.
Kind of Cpu and heating related but not sure what can be the solution cuz when the phone is colder not restarting that much like warmer.

I haven't tried a new battery, yet I have two batteries, one was the original and other was bought at the same time I got my phone 2 .3 years ago, I have also tried to boot my phone plugged in, and even safe mode, but no success. Both methods only took it into the boot loop.

First thing i bought new battery but didnt help at all.
It is most probably cpu heat sink problem , that heat sink doesnt work anymore i guess . Now phone works like normal with low cpu freq. but a bit slower ..
One day i will try to change heat sink on cpu but dont know when

So do you have similar problem? and how did you get it to work at low cpu frequency, I don't mind it being a bit slower as long as I get back to my data on my phone.

I have same problem but mine at least opening .. when you can not start the phone , you can not change the freq of cpu.
I did mine with root and app called "no frill cpu"
For starting you can try to put your phone in to freezer 2 or 3 mins (not make super cold) and then start it when it is cold , i managed to use my phone like this around 10 min. so then u can change cpu freq
But today it turn off itself and so far couldnt turn on again ... looks like it gets worse in time..

No problem , tell me if it works.
I just try right now mine and all day it was restarting but i put it in freezer 2 min. and tried and it turn on ..
I am wondering all problems are same from cpu

Few mins. ago i opened up my lg g3 and apply heat sink on cpu chipset and so far it works really better than before
I even tried normal cpu freqs. and it didnt restarted , before using heatsink it was not even possible to see main menu on high freqs.
I was already thinking to buy new phone and spend so much money but then i give it a try and it works. I dont know how long it would help but so far so good.
So i would recommend anyone who has this bootloop problem to try heatsink gel on cpu if still problem continue then you can throw away the phone i guess

Hello, I've battery problem and it keeps restarting by itself, So I decided to buy new battery and with new battery still problem exist and it's random, after 2-3 min usage it restarts.
What should I do ? the phone was working very good a few days ago and that battery was fine until this stupid restarting happened and even I flashed the stock Rom but it didn't fix it.

Thanks for videos, I don't know how but I was able to use the phone for 3-4 hours and for test I used Antutu benchmark and I got 53.000 score, When I tried to charge the phone it turned off and I tried to turn it on again it stuck on Lg logo and I heard some noises sound and phone stuck on logo ( sometimes it has boot loop), For now I turned off the phone and tomorrow I'm gonna buy Thermal paste, Hopefully it will fix it.
Did you have the same kinda of problem ? Like phone stuck on Lg logo or it turn off after you try to turn it on .

How do I know if my G3 is dead? It doesn't do **** when I try to turn it on, it just vibrates and stays there. When I connect it to pc, it detects a connection but nothing happens. This happened earlier this morning and it doesn't want to boot back up no matter what I try.

My phone suddenly turned off and repeated to try to turn on itself but sometimes it was just bootlooping on lg logo sometimes just seeing lock screen and turning off . Noise stuff i dont know but mechanically there is nothing to make sound i think so dont know from what but i never had it.
You can try another working battery and software format. If these doesnt work then you can make thermal paste thing .. but if you think it is easy to do thermal thing then just start with that.

There is no point in software changes -- it's a hardware issue. I don't understand why no one checks the forum before asking -- there is a ton information written on here alone, and how to fix the issue.
You need to fix the loose connections and heat problems of the phone.

Thats right. All you have to do is applying a thermal on SoC. It did work for me

zuk stuck with led on after 5-10 seconds

Actually i switched from zuk z2 and it's not my primary device but still i want to use it as a secondary Device but a serious issue is happening with the device for a long time and that's why i switched from z2 ....
Actually my z2 automatically turns off in 5-10 seconds and the led glows .... I can boot into recovery but it also stuck after few seconds and led glows .... Phone is totally functional but doesn't stays on....
So it literally become useless and can't be used anymore .. . I guess it's experiencing some kind of hardware failure... Can anyone help me with this issue??

Is it charging in twrp and is the same issue in twrp.as well??
Try a light ROM non treble like cardinal etc and don't use phone .
If it remains on in standby then battery is gone coz under heavy load kernel panic is happening due to low power/voltage from battery..
Go for battery replacement.

Greetings Pal and sorry for such late rly.
??
Btw i would like to inform you that even my zuk z2s battery life got degraded so bad that any rom i flash, the battery dont last long. In standby mode battery drains to almost 5-6%. Using lineage OS 16 with minimal gapps. But still battery drains like hell. If u hv tried out every thing out there to fix ur device, and still u fails, points to the battery failure. I think our zuk needs a battery replacement. I ll inform u if i found some decent battery for our beloved zuk. The bad thing for me is i hv to replace my speaker too along with my battery as it sounds verry terrible
