[Q] [Help] My battery is draining too fast, some soft problem ?

I bought this Hero off eBay, and it was dodgy since the begining.
The phone had cyanogen, and was restarting itself occasionally.
So i wiped it, installed 2.1 and it got fixed, but now i have a problem with battery drainage.
Its insance, 10minutes-10% im pretty sure its not supposed to be like that. with or without wifi/3d turned on, its just riddiculous.
I borrowed battery from a friend, and that didint make any change, i installed latest update from the autoupdate in the phone and still its bad. I read somewhere here that its faulty email app that keeps on trying to sync and drains battery, how do i fix that ?
I did a full wipe, cleared cache and everything back to factory settings, with no apps installed it goes from 100% to 0% in an hour.
I downloaded 2.1 from some android forum, as i was unable to find one here (there are only links to 1.5 on the xda.wiki WHY?)
If you can point me to a proper 2.1 (or higher?) software to download that doesnt do this crazy **** i'll be happy as infant on crack.
Please help, here is my software information:
Firmware: 2.1-update1
Baseband version: 63.18.55.06JU_6.35.09.26
Kernel version: 2.6.29-063c4d24
Build number: 3.32.405.2 CL191507release-keys
Software number: 3.32.405
Browser version: WebKit 3.1

Try calibrating your battery it gave me a huge boost on my hero... went from getting 16hours day.. to about 30hours on a single charge!!
Every time you flash a new ROM you need to calibrate your battery. The battery meter in the OS (Android in this case) is generated based on the battery stats file.
Battery stats is erased when you flash a new ROM.
Easiest method of battery calibration when you're intending on flashing a ROM:
Ensure battery is fully charged according to the OS. Switch phone off, unplug charger and plug back in. Once light is green, leave charging for another 30 minutes (light goes green at approx 95% charge).
Switch on, flash ROM. Allow first boot to complete.
Shut phone off. Disconnect charger. Remove battery. Replace battery. Place on charge, light green, leave charging another 30 minutes, yadda yadda. Switch phone on, boot immediately to recovery. Wipe battery stats.
Boot phone up. Now would be a good time to install JuicePlotter. Use as normal. Do not charge, let the battery run down completely. When the phone shuts itself off, power it back on. Repeat process until it won't switch on anymore.
Remove the battery. Put the battery back. Turn the phone on. Repeat until it won't turn on anymore.
Now charge the battery on the mains to 100% while the phone is off, keep charging for 30 minutes after light goes green. Power on. Voila, fully calibrated battery.
The last part, run until completely dead and charge only needs to be done once in a while (this is calibrating the battery innards, not the battery stats)

hah, yea thats what i accidentally figured. phone was switching off, but when i powered it back on it had 30%.. and it was like that 3 or 4 times.
I ran it down completely and now am charging it till max, we'll see what happens. at worst i'lkl start your process from the beginning thx !
I diidnt know you had to do that. i've been playing with my G1 and not even once i had to calibrate that.. maybe i should

How'd it go? Any improvement on battery life?

it diidnt help I did what you quoted step by step and its still running down the battery like crazy :/ what else can i do ? im thinking of switching to 1.5 but thats just not progressive and my friends phone is running fine on 2.1, with the same battery even.
Edit: i've installed task killer and killed all the mail checking apps.. hope that is the problem
Edit2: it didint help at all, in 5 minutes i lost 15% fcuking hell !

I just switched to 1.5 and its still happening ! I using a different battery and its just as bad... why is this happening to me
ill try second to latest radio from xda wiki.. im running out of ideas,what else can i do ?

That really wierd... its not the battery if you have tried using different ones. Its not the ROM if u have changed it.
Have you tried disabling auto-updates? and auto-checks for emails. Which email client do you have? you should find the option to "sync-never" in the app settings.
Buying it from ebay is kinda ominous though.. was it described as faulty? perhaps you could contact the seller and request a refund is all else fails?

you can try using setcpu to underclock the cpu.
i have similar situation as you. before going to bed around 11pm, it showed 50% left, turned on airplane mode, then in the morning around 6am, phone was powered off.
now it has been 2 days, still have 20% left.

Did you ever take into consideration that some part of the hardware might be damaged?
Devices that got water damaged, sometimes show weird symptoms as well:
- They still boot up and seem to work well from the first sight
- The battery drains very quickly
- Some of the peripherals are not working stable or not starting up anymore (e.g. wifi, bt, gps)
- Other crazy things might happen as well (e.g. random reboots, backlight flicker, etc.)
So you might have a look at the mainboard. Red stickers indicate water damage!

Yea but if it were damaged would it show 50% battery after restarting thinking it had reached 5% ? i dont have the tools or will to unscrew it.
i paid 100 pounds fo it, the normal price of a used hero, but the auction said "phone restarts for no reason" and they do not accept returns, so im propably screwed :I

I had an old blackberry 8300 curve, i had it in the bathroom while i was showering, got too moist, turned the detection pads red but phone seemed to work fine after i dried it out. But the battery went to crap progressively in the manner. I would charge to 100%, take it off the charger and maybe an hour it would say less than 10%, do a battery pull and it would go back up to maybe 80% and last maybr another hour and keep doing that till it would normally drain on top od the numerous reboots i would be doing until eventually it would just drain and die.

Can dead pixels cause this ? i have like three.. but then again why would it show 50% after restarting from 5%..
the thing is its not draining the battery, just registering it wrong

Any updates on this? Any resolution?

sorry mate i have tried everything unsuccessfully and returned the phone to the seller.. dont tell me you bought it ? (london)

No, but i have a samsung galaxy tab and experience similar symtoms. It does not bother me too much, the battery life is still great. Just the percentage is off and i need to restart from time to time.
I read similar complaint from droid x forum too.

Galaxy 3 Shutdowns

It happens only when I turn on 3G or I do some installing or I play a game. It says there's low battery and the phone starts shutting down. I've rooted and tried various ROMs but still nothing. What could be the problem? I don't think its the software because I tried rerooting and hard resetting. Any help would be great!

Well it says low battery then it must be because of low battery. Maybe your calibration has gone wrong. Just recalibrate your battery and check.

Nope it's definitely not because the battery's low I charge it to 100% then for maybe 2 hrs its fine. But once I turn on 3G and use it for 5 mins it automatically shuts down. If I try turning it back on it does the same thing what can I do now? I tried to recalibrate the battery many times still nothing. I'll try some more but what else could be the problem?

Try changing kernel?? Increase minimum frequency. Maybe. If problem is still there. Flash your regions stock ROM and go to service center. Replicate the problem there.

Yeah I think I'll take it to the service center but before that I'll try what you said. Thanks for your help!

What if you keep the phone plugged in with the charger and then turn on 3g or install something? Does it turn off even then?
If it does not, the problem is with the battery so replace it.
If it turns off even when charging, something else is causing the problem so take it to the service center.

dude i have had the same problem. i did send it to the service center - will get it back tomorrow if not, then for tuesday for sure..i know what your problem is .. your phone does draine the battery very fast - if you do something, or not isnt it? then when you swith your data connection on, your phone drains the battery withing 5 minutes to 0%. in reality its not a battery problem - cuz i tried another battery of a friend and the same thing happend again. but the battery of my friend isnt bad. :S

Nope it happens only when it's on battery and yesterday I found out that it happens when I make calls too. When it's charging everything is fine. I'll try changing the battery then.

Yeah that is exactly the problem I've been facing too! In 5 minutes it switches off I've even tried different ROMs. Well since you've given yours for service could let me know how it goes? Thanks.

Yes. I reveived it today.. seems like the problem still exists -.- i dont see any changings.. it looks like it was just a waste of time to send it to them -.-

have you tried changing the battery

I have the same problem since one week (shutdown while i use 3G or Wifi, but battery is full !)
Revert to stock ROMs doesn't change anything, i've tried o lot of them (was on cyanogenmod before)
I probably get the Galaxy Nexus next year ; but it's a very very annoying problem..
I can't do anything (no calling, 3G or wifi using, pictures taking..)
Please help us.. if it's possible

Yeah I tried my friend's battery but still I have the same problem.

Oh that's not good but I'll take it to a service center asap and hope they fix it. Otherwise it's time for a new phone!

[Q] i9505 turns off when stressed

Dear Friends,
I'm having a rare problem with my S4.
All used to be fine but now suddenly the device turns itself off when it's stressed. By stressed I mean during a call while switching to another application or watching a video for more than a few minutes. To me it seems like a battery broken because once I unplug the AC cable and run the benchmark the phone shuts off and usually when it gets to the GPU/Video related tests. When I plug in the AC cable and run the test everything works as usual.
Also when the phone has turned off randomly the phone has problems booting up. It will get to the omega boot animation restart again. The intervals are always different. Sometimes the logo spins for a few seconds and then it reboots again, sometimes it happens right away when the logo appears. Its almost that the phone does not have enough juice to boot up eventhough the battery is charged with 40% or so.
Once I plug in the AC cable the phone boots up normally. I doubt that it's the custom Rom (Omega 9.0 with stock omega kernel) that is causing the problem. It seems hardware related. I'm guessing:
- GPU
- Battery
What do you think is causing those random turn-offs ?
Should I exchange the battery or flash stock rom to check if it still happens?
Why does it make a difference if the AC cable is plugged in? can it be anything that is not battery related?
I'd love to have your opinions!
Best,
Thomas

Your using XXUBMGA right? I had this weird problem where the screen wouldnt turn back on unless i pulled the battery. I switched to the german firmware and all is fine. Its not hardware, trust me, same prob.

First go to stock rom mate, then check

Weird thing is i was using stock, even though exxi is using a modified rom it might not play nice with root/custom kernels. Dont know for sure though; just what i have observed directly.

Friends,
I've installed the Pre-Rooted Stock Rom UBMGA via Odin. Cleaned the phone completely. It booted up and during the first Sign up process (google account, wifi network setup etc.) it went off again with 80% charge. When I plug it to the charger I can continue the setup normally. It seems that whenver it starts any GPU related process (Video animation, Antutu menchmark, Quadrant, Games) it turns off without warning. I ordered a new bat. hopefully it will arrive next week but until then I will not know if the issue is battery or phone related. at this point I doubt that it's ROM related. What's your judgement on this?
Best,
Thomas

Any news? I've had Omega v7 and like two weeks ago it started to turn off suddenly... I thought battery run of or something, later on when this turn off happened and I turned phone on I had "black screen of death" or what to call it.. no launcher but status bar was ok, when I dragged status bar down I could open settings and change "homescreen" to basic and than back to normal and it worked...but... I couldn't use home button, it just showed black window that disappeared immediately. I backed up data and flashed Omega v11, after "tutorial" just after choosing language it showed this black screen again, so I've begun being suspicious it's hardware related. Morning after that it was working okey. Well...not really.. in app list one page of app was showing shadows of icons instead of icons, when i scrolled trough all pages it fixed. Later that day it turned off again. No turning off omega symbol, just.. like if you pull out battery. And those shadow icons were on two app pages. I've flashed nandroid backup of original ROM and when I browse gallery fast it turn off again... I suppose it's hardware related as it's not stuck to specific ROM. Maybe wrong battery? but more like motherboard I think. It also broke my sd card, because of multiple power failures probably. Also after this turn off battery drops down for like 10% or more. First screenshot - shadow icons..second screenshot - battery % drop

i have the same problem with one of the last stock release, in last 2 days my phone's system was totaly burnt because i've played a lot with roms kernels and tweak, and it started to give me also this kind of problem. So i flash by odin one of last stock firmware and it's ok, after a few minutes i've rooted again the rom and charged phone from 19% (at this percentage the phone turn off) to 100%. it seems to be okay, but at 63% it turn off again, so i pull out battery for some minutes, and after it continues to turn of after a few seconds...
(one of the tweak that i made was using "battery calibration" it clean battery stas that can be damaged by skipping between various rom, i used it a lot on galaxy nexus but maby this can be one of/the reason of problem)
Have u resolved by changing the battery???

Dear folks,
It's a battery related problem. When I changed the battery for a mumbi type new battery the phone works with no turning off. Problem resolved

[Q] help, phone reboots and battery turns 0%

ever since installing arrow rom V8, my phone sometimes crash and reboot from opening certain apps or even taking a picture... but that's not the weird part, its when my phone reboots and turns on again, but with the battery at ZERO percent. This happened 3 times already, and only on arrow rom.
When i take out the battery and put it back on again, it's still at ZERO percent battery... to solve it i have to turn off the phone and plug it in the charger at the same time.
Any advice why this happens? do i need a different kernel or a new battery?
thanks
im using i9500 octa version.

My guess is a new battery. Samsung already stated that some phones have bad batteries.

Samsung has started replacement of such batteries. Go to your nearest service station and get ur battery replaced. Even mine had the same problem but now works like a charm.

Battery/Network/Root - The Problems with my S4

Hi,
I have some problems with my S4.
1. the screen flickers sometimes when 1 have a white background
2. the phones shuts down when it's under 30% (sometimes at 29%, sometime 22%). Then it's note possbile to power it on again. It boots, but then shuts down again. If I charge it, it turnes on and the battery percentage is about 30%
3. sometimes the phone just shuts down (can happen at any percentage, even >90%). Then it is stuck in a boot loop. It shows the Samsung logo, the screen brightness goes from 100% to automatic (display gets darker), phone vibrates and starts again.
Then I have to take the battery out for 3-5 Minutes or charge it. Both works but when I turn it on again the battery percentage has dramaticall dropped (like 90->60%)
4. The Network reception just stops. The notification bars just shows the crossed circle. when i try to find a network (any of them, not even my own) I get "Error finding network". It takes 5-10 Minutes for it to appear again. Restarting the phone works too, but mostly, due to point 3, the phone is in a bootloop then.
Some solutions I think might help:
1. (i hope turning off automatic contrast fixed this, i will see in some days)
2/3. Bought a new Battery, hope that will work.
4. ?????
I think 2/3 are related to wireless charging with a chinese qi-Station. So i won't recommend that to anyone.

What model of S4 u own?
