Very hot phone, battery life under 2hrs

I was recently on one of the old Dutty ROMs (V2.1 XTREME) and decided to upgrade to something newer, so I got the latest "phoenix" EnergyROM (Dec 17th) and flashed that using USPL SD bootloader.
The problem then arose that they phone was always extremely hot, specifically on the back down the bottom just above where the plastic cover for the antenna(s) is.
The battery would not charge to 100% and tBattery showed that it was drawing up to 400mA all the time, this is when plugged in and sitting on 99% charged. On a call (while plugged in) for ~20min the battery will also drop 50%.
I then did the following, which has had no affect;
Hard-reset, flash "leo" EnergyROM, hard-reset, flash Miri 6.5 ROM, hard-Reset, flash to the original Dutty v2.1 (when it was working), hard-reset.
I have tested the phone in-between all these procedures and even tried using a different (aftermarket) battery, all to no avail.
The engineer in me says it's a hardware issue, but I would like to think it's a software issue, something running at 100% consuming too much power.
I'm now looking for any ideas or advice on what could be the cause, since I have a phone that is practically unusable when not plugged in.
Cheers!

Could also be a faulty battery as I've tried to roms you mentioned and did not have the same issue with battery. If not battery it could be a hardware issue. You can buy a cheap battery easily to test this

I've already tried a second battery as I mentioned, doesn't make any difference at all.

Have you ensured that all data connections are closed, Beam turned off and no automatic updates are ticked (weather, stock, email etc). If so, then it sounds like a faulty device.

Does the exact same thing even with wireless off and in aeroplane mode.

Defo faulty device then

Hi Gussy,
I agree with Fallen Spartan and I think it's a hardware issue (battery issue).
Please try the following:
(1) Charge the battery to 100%.
(2) Disable from running or uninstall any 3rd party applications.
(3) Disable Bluetooth and Wi-Fi,
(4) Enable flight mode
(5) Set backlight to maximum settings.
(6) In the power management settings, uncheck any option that would set the backlight to turn off.
(7) Let phone stay idle for 1 hour and check battery capacity.
(8) If there is a loss of 40% or more, then this means that battery is faulty and needs to be replaced.
Regards.

Battery won't charge to 100%, only 99%.
I have done pretty much that test already, a few times, with the original and a new battery, and neither lasts the 1hr.

Ah sorry, yep sounds like a faulty device. Is it under warranty? I don't think you could even flash back to stock ROM and Radio if you are planning to return the device (even if still under warranty) because of the power consumption issue

It have about 7 days of a 1 year warranty left, from the eBay seller I got it off. Sent the guy an email, don't expect a reply though.
I can flash back to stock, I just keep it plugged in and it works fine.

Ok mate. I suppose you have done all that can be done. Hope the warranty situation works in your favour.
Best Regards.

hmmmmmmmmmmmmmm interesting.
my hd as been displaying the exact same symptoms for near on a month now,
i assumed the battery was cooked but its near identical to your issues,
i aquired a hero around the same time it started playing up so i aint been that bothered but reading this got me thinking its time to think about sending it off for repair.
if as i think you meant nrgz28s rom then i also flashed the 17th dec 6.5 dusk rom build 28014.
i cant be 100% sure thats the exact time the problems started but its very close if not the exact time.
the phone was purchased around mid december last year so about the same age if yours was new.
coincidence or contract concspiracy lol?

Could this be caused by a faulthy radio>!

Hmmm, could be, but most probably still the hardware error.
Altough, combination of very mismatched radio and RIL could cause simillar symptoms...
Best check this thread: http://forum.xda-developers.com/showthread.php?t=466274

I had a similar problem.
Drain battery to about 5 - 10%
Turn phone off
Charge from a wall charger (not usb or car)
Do this a couple of times.
It fixed mine for about 6 months and then I just did it again and it sorted it out again.
Also check which radio. 1.17 seems to run cooler by most accounts.

I was initially thinking that there is a program or piece of software maxing out the resources and the cpu causing the extreme heat (the HD gets bloody hot when being pushed) and poor battery life.

[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!

scholbert

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.

Power related issue

I'm finding that sometimes when I plug in the tablet to charge even if they battery is almost full, as soon as I plug it in it will think the battery is at 0% and start shutting down.
When I power it on and look at the battery stats it shows that the battery went to zero and then goes back up to were it was before the shutdown.
Also another issue is that the battery status will say its not charging even though it's not plugged in and the level never goes down even after a reboot. I find to fix it I need to go into a custom recovery and reset the battery stats for it to return to normal for a few hours.
I'm running on the stock image.
Its annoying, but I'm hoping that the next update will fix this.

Can't say I've ever experienced such an issue, on any device. If your looking for a fix, perhaps reflashing the factory image completely might help (I don't understand the battery stats file too much, but I would think a reflash would probably replace that file, and fix the problem).

I thought I was the only one with these problems. Never had these issues on my Galaxy Nexus. Now on the N10 I have the first problem you mentioned + battery % not moving until I reboot the unit (Random). Very annoying...I called Google Play support and after doing some test told me that they'll send my a new unit.
Note: I've flashed the Google image and I still had the issue (seems less frequent)...Sometimes I can have the % correctly refreshed and sometimes it stops after a few minutes.
I've attached screenshots of the problems...(1st image) Long straight lines were when I was actually using the device!! Cut in graph = reboot
Second image: both problems, check out the spike a 0%!! when plugging usb cable

I have the same issue and my replacement is on it's way.

So I called support and I'm getting a replacement device.

I've been searching everywhere, thanks to this thread now I know I'm not the only one having these exact same issues. Looks like I'll be making a call to Google Support

Probably a software issue to be addressed in a later update.

Are these issues still present on the replacement devices?

So far not happened on my replacement device. Went from 70% to almost 10%. Still testing. Also wakeup time is normal. I think it was hardware related.
EDIT: on my 3rd day and this new device always correctly reports battery life. Definitely hardware.

I'm having the exact same issue with battery % not updating at random times and then sometimes the n10 claims 0% battery after recharging overnight and promptly turns itself off. Did the replacement unit fix this for you?

Yes my replacement unit is perfect. On my fourth day now and no issues whatsoever. My first unit was doing it day 1.

I got my replacement unit 4 days ago and the problem is definitely gone! On my first device it also happened since day one.

My Nexus 10 just started doing this after a reboot last night, I guess I'll have to ring support and get a replacement.
I'm running a custom kernel, recovery and unlocked bootloader. Do I have to flash back to complete stock before I send it in?
Cheers guys

I'm not sure if I have this issue, but my N10 is definitely acting strange.. I put it in my bag this morning on 42% charge and when I took it out in the afternoon it was dead (I thought I might have hit it to something and damaged it), but when I plugged it in it started to charge after a few minutes from 0%. Then it rebooted after like 5 minutes without me touching it and it's charging for now. The battery stats don't show a drop to 0%, the graph ends at 42..
I've had this device for around 3 months now and never encountered this issue before, so I'm not sure if it's really a hardware issue, but I'd be quite disappointed if I had to get a replacement as this one is a really good one in terms of the other common issues (bleed, throttling, creak).

[Q] Phone is very warm and drains battery, even when OFF!!!

About 3 weeks ago my phone started acting up with fast battery drain (about 20-25% per hour) and would be quite warm (90F in normal room temperature while idle).
Some notes:
It's warmest around the camera lens
CPU use is low/nil
Turned on power saver and airplane mode, same deal
Becomes even warmer if I charge it while phone is on
I've swapped in another N3 battery, same deal
I've taken out the sim and memory card (Samsung EVO)
I've done factory resets and formatted the memory card, same deal
It doesn't matter whether I have strong or weak reception.
And the best part...
the phone is slightly warm and the battery drains even when powered off (about 10-15% per hour)
I was on Hyperdrive 7 (4.3 and MJE) when this happened. Took this chance to update to the DeOdex 4.4.2 and now on NC2 but whether on stock rom or Hyperdrive 8 or Alliance, the problem still persisted.
I've tried searching for anyone with the same problem as me both on these forums and on Google, no luck. Closest I found was a bunch of guys in Singapore where going to another SEA country overworked their antenna but their problem was fixed as soon as they returned to Singapore.
Any suggestions?
p.s. I bought this phone used. Assuming I have to call Samsung for warranty service, will they want me to be the original purchaser? I don't have any documents showing the original purchase although the phone's manufacturing date is December 2013 so I'm clearly (though barely) still within the 1 year warranty period.

For warranty I believe they ask for the serial of the device also I had nothing but issues with Samsung reps so word to the wise call get it replaced don't tell them it's used act like it's yours and get the most of the warranty if someone gives you issues hang up call back completely different person will answer and eventually give you what you want. Took me 3 months to fix my charger issue on my note 3 5 reps lied to me saying it was shipping when in fact they just wanted to push me on to someone else and I wasn't even in the system when they act like there looking you up. I eventually talked to a manager that said they did everything wrong from telling me how to ship arrival etc so this is my advice don't give up don't listen to all the reps most don't know anything about phones if so ask to talk to a manager or supervisor that is golden good luck

They wanted Proof of Purchase (receipt) from me when I wanted just a cable replacement....so you may be SOL if you don't have proof you purchased it.

After updating to 4.4.4, my phone was doing the same thing you described. I went into Wi-Fi settings/advanced, and turned off "notify me when Wi-Fi connections are available"; changed "keep Wi-Fi on during sleep" to only when plugged in; and turned off "always allow scanning". After changing these settings, my phone is no longer overheating when plugged in or sitting idle and my battery consumption is back to normal. Apparently my Wi-Fi was constantly scanning, whether on or off, and keeping my cpu clock almost maxed. Again, after changing the settings, the cpu clock has settled back down.

I have the same problem. Where is this WiFi Settings/ ADVANCED???
Found it- Thanks...

I had the exact same problem. It worked fine for months and suddenly wouldn't hold a charge. Same issue, even turning it off and trying to charge, it couldn't keep up. I tried different chargers and batteries and even did an ODEN back to stock. Nothing worked. Then suddenly it quit draining the battery, with no explanation. Very odd.

Crashing, turn off and massive battery loss

So a few times now my note 4 has crashed (black screen) and turned off. When I turn back on the battery level has massively dropped (30-40% gone) yesterday went from about 40% to 0%. The 40% seemed accurate as using it not too much and usually about that percent at that time of day. Also noticed a few other things, when I connect my note to the pc it takes a while to start and stop charging and isn't being recognised by the pc (or the note isn't detecting it is connected to a pc - only charges)
Any ideas?

Try a different battery?
Are you rooted or custom rom?

Hi, not rooted and stock rom. Had an update yesterday which mentions better battery performance. maybe they fixed something. I'll give it a week. Have also contacted samsung. Not sure if battery is included in the 24 month warranty

I'm running stock 6.01 deodexed and rooted, It's happened to me a couple of time. Either its a samsung bug or the battery is just recalibrating itself. Probably the recalibration

That's good to know but worrying. Its really bad if it happens when I'm out. I think I have a good 10 hours of battery and then bam nothing. If I get anywhere with Samsung I'll post back
