Question: Has ANYONE figured out a...

...definitive solution to the overheating (and subsequent crap battery life) issue with the Tytn/Hermes/8525?
This seems to be one of the most prevalent hardware-related problems I've encountered after perusal of numerous boards.
Charging, it heats up. Duh. Fine. Disconnect, put it in my breast pocket after it cools down, twiddle my thumbs. During this whole time, for purposes of this test, EVERYTHING is switched off: phone radio, wifi, bt, push, and as many of the background processes as I can kill without having the phone hang on me.
You'd think the symptoms would be the same every time. But nooooo...this thing has a mind of its own. Sometimes it'll be 5 mins before I start feeling the heat, sometimes 40. It's totally unpredictable. I've tried every way I can find to extend the battery life with no luck; this is getting retarded.
So: Battery life drops drastically once the thing starts heating up. But not before. From 3PM to 4PM today, battery life was at 100% and did not move. Sweeeet! I thought...too soon. Got that warm and fuzzy feeling - then it's in free fall. 10% down in 45mins, another 20% by 5:30, dead as a doornail by 8PM. That's exactly FIVE hours of "standby" with ZERO activity. Screen was turned on maybe 4 times just to check battery status. 200 hours of standby?? Sure, in a deep freezer packed with dry ice...
Installed Batti: if anyone with close to normal (advertised?) battery life has also installed it, could you tell me what your temperatures are like? When I'm charging, I'm at 35.6C. My voltage is at 4.213V - this might be the problem since the battery is listed as a 3.7V 1500mAH. Also, I removed the charger for about 30 seconds after Batti said it was charged, then reinserted it. It took about 30 minutes to tell me again that it was full - all the while listing the "Percent" as 100%. Gah!
Anyway - back to the reason I've posted:
1) Is this a phone issue, tweak/registry/software issue, or a good old fashioned battery issue? I've got another battery coming in shortly but it's nothing special, not sure of the brand, just want to compare it to this one - which is a Seidio.
2) If anyone else has had this problem and solved it, please let me know what you did.
3) This phone is for sale if anyone wants it and knows how to fix it. Other than the 5 hours of battery life, the phone is perfect.
Thanks all!

The only time I've ever had this problem was when I installed the very first Palringo mobile beta, and it continuously polled the Palringo servers whenever it was connected... I had a battery life of about an hour and a half!
I can only suggest you have some poorly-written app on your device which is polling some piece of hardware or using (or trying to use!) the data connection, subsequently failing and looping round to try again and again.
I'm not using Batti (using the BatteryStatus Today Screen plugin), but it shows temps - I'm charging my device at the moment and it shows ~41 degrees celcius. When I unplug the charger, I have about 70mW usage and when I tap to turn the backlight back on it roughly doubles (backlight on its lowest setting). Using roughly 40-45mA just idling, I have push mail turned on and ActiveSync is syncing probably every 5/10 minutes or so (can't remember the interval).
I get about a day's worth of usage including regular phone usage, data usage, then locking the device (including turning the backlight off) when it's just on the desk or in my pocket (less if I have BT turned on all the time, obviously). All I can think of is that you have some app on there which is either interacting with something else or causing the problem itself.

@slidizzy:
what is the manufacturer name on the battery?
There are threads around about certain manufacturer brands (there are a couple of different brands) and their performance..
i had a dynatec and it was crappy.. took it back and got a sanyo battery and all was good...

Possible solution - Same geographic location
Hi. I seemed to have the same problem recently. I think my radio was the new 1.54.00.10. I have two batteries and each one was killed in 6 to 8 hours.
I first downgraded the radio to 1.51.00.10 and it seemed a little bit better, but upon upgrading to 1.54.70.00, it seemed to have gone away. My OS is Pandora's 7.1 w/ 3.62.
With 1.51.00.10, I was able to get over a day's worth of life on one charge in 3G/H mode. It seems this 1.54.70.00 is giving me more life, but I'm still testing.
Maybe give this a try, upgrading to 1.54.70.00 and a 3.62 os. No problems for me so far and it seems like it's a keeper!
Hope this helps!

Soft reset when it starts getting warm, soft reset after charging if it is warm when on the charger.
My 8525 used to have this problem, but it went away on its own. However, soft resets when the device felt warm did solve the problem when it was occurring. Note that my phone is no longer warm while charging, either.
A lot of people try various radio upgrades/downgrades and ROM changes to fix this, but I think that's on the wrong track as I've never seen anyone report that doing these things made any difference. However, if you're not using WM6, I recommend at least making that change.
Other than that, hit the reset button if it starts to feel warm for no reason and after charging, and you should be fine.
My guess on this is that there is some kind of problem where the device thinks it is plugged in when it isn't, and then it over stresses the battery causing the heat and fast battery drain.

My experience
I am on Rogers in Canada, the same company that owns Fido, and I wonder if there is a problem with their network/ActiveSync/3G/units compatibility.
carrier: Rogers wireless (Canada)
device: branded HTC TyTN WM 5
ROM: 1.34.631.14
Radio: 1.42.00.00
Recently activated Push Email and connecting to exchange server via Activesync. Push requires an "always-on" data connection. It seemed to have been working fine for about 2 days, then suddenly my unit started to heat up significantly, (luckily no screen warp), and my battery would drain from 100% to 0% in 5 hours (if I was lucky). Unsatisifed with Rogers suggestion that replacing the unit with a refurbished unit was the way to go... I continued my research and experimentation and 48 hours later here is whatI came upwith so far:
1) Hard Reset - did not help the situation
2) Soft Reset when heating up - did not help the situation
3) Most frequently associated activity - ActiveSync on with 3G Data Connecton enabled and server directed to exchange server... no difference depending on how often I had the mobile device ping the exchange server. The heat and battery drain occurred while the TyTN was in hibernation (dead unit in the AM when I awoke).
4) Battery drain modifiers - worsens with worsening heat, worsens and acclerates if you remain in an area of low signal (less than 2 bars showing)
Best solution(s)/explanation(s) to date:
1) 3G is a battery killer - it uses a lower intenisty signal, and it generally draws heavier on the battery and hardware when using the network
2) In Phone settings, switching your Band to GSM (2G) fixes the device into one band (does not allow automatic switching and constant detection of best signal). Unless you are a real Power User and rely heavily on every ounce of speed that can be squeezed out of 3G there is no noticeable difference.
3) I have switched off the "receive allincoming beams" for the Ir interface to conserve every mV of power in my battery.
4) Since the switch (a few hours now) I have had no heat issues and the voltage has remained stable with ActiveSync on and mild websurfing to download a couple of CABs... granted it is minimal usage as it is 2:30AM but I think this may be the trick (on Rogers with a TyTN anyways)
I'll keep an eye on this and do some more analysis on the battery... Any input readily welcomed...

sounds like you simply need to buy a new battery.

It's not a tumoh!
Doesn't seem to be battery...
I recently tweaked reg with some battery hacks, locked it into 2G and all has been well. Holding a charge with the data connection engaged 24/7 - drops to about 65% charge over 24h, having to charge only every 2nd/3rd day...

Phone gets hot during 3G use

When I use my Nike for more than 2 minutes while browsing the web using my 3G connection it gets quite hot on the lower part of the backside (isn't this the area with the cpu/chipset?). Although I have not measured the exact temperature it gets well over 40 degrees celsius on the outside already.
I also notice a lot of battery usage but that might also be because of the screen being on all the time, though the chipset might be sucking away a lot of battery power as well, judging from the heat dissipation.
Is this behaviour normal or should I go and have it checked/repaired?

It's normal. Mine's the same.

I got a new Niki after my old was damaged, none of them gets hot.
As far as I know this could be caused by a wrong Radio Version. Did you flash the Niki with another Radio Version than shipped?
High battery usage could be caused by some tools (e.g. S2U2)

Nope, the phone is running a HTC original WM6.1. The phone isn't even hardspl-unlocked
The windows installation itself is pretty clean: no special tools except total commander, opera and tomtom, of which none are running.
You state that it does not get hot. Does it get warm though, or really nothing special? Are you using GPRS(2G) or UMTS/HSDPA(3/3.5G)?

Yes, I'm using 3G. My phone is only a bit warm when connection to PC and flashing/trying ROMs (> charging & lots of CPU usage)

Mine heats up when using the data connection as well. I've got the standard radio rom.

This is a well known issue in NIKI, don't worry (except if the temperature is too hot); but i have tried many radios and it gets hot when you use HSPDA.

this is because when you connect it to usb it also charges the battery which the connection for the battery and i believe the processor are at the same board. It usually gets hot where the sim is located under the battery. if you use the phone alot to call also it will get hot. i don't think it's an issue i think it does that because of the location of the processor..... Yes i did open my phone

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.

Running a lil hot?

I've noticed it previously during usage (like on the internet while having MSN running, or while playing games)
but I just got off a phone call which lasted about 20 minutes, and the front (and back) of my phone was just too warm for me to ignore. I would have suggested that it was the heat from my cheek against the phone but that wouldn't explain how the phone was quite noticeably warmer than my cheek.
The backlight wasn't on (i doubt the LED backlight would cause much heat anyway).
Does the mega have any internal temperature sensors like PC's have? And any software to read them?
My previous phones NEVER got this hot on even hour long calls,
and mix this with the fact that at my work one of the PDA's blew up a few weeks ago (was the battery), it just makes me that more paranoid!
I am going to Hard Reset soon anyway as things started running a little slowly recently, I hope it will also stop any hidden processes that may be running in the background and overworking the cpu. But I would still like to know of any software

I think its pretty normal to heat up during long conversation. Their manual also says "Using any function for long time will heat up the phone", but only upto a level.

i've never experienced warming of the phone which is coused by operating it , well maybe just a lil utube watching for an hour but it was warm of my hands , i'm only worried when i leave it charging and after 15-20 mins LOL ! the phone is HOT i know that is normal , just sharing opinion

Heat comes from 2 sources in general external and internal.
External is from sun, your hands or phone in your pocket. On longer run this is not good for battery life.
Using navigation in your car during summer can run your phone real hot and feels quite uncomfortable! From a 20 min call it should not. But this is subjective.
Internal heat is caused when your processor has to work hard; like when several programs running and processes in back ground. You can check and kill them with task manager (FDC soft task manager) and batteryguard. Also soft reset kills most "unwanted" processes. A good indication for high level of processor activity is when your battery level goes quickly down.

Its normal mate, on mine when i use GPS for long time it does the same, processor works hard and battery gets hot.

Not sure if navigation alone causes your battery to run hot. Since navigation can run on 200Mhz processors and Mega processor has much higher clock speed it is overspecified.
The influence of phone close to windscreen and therefor impact of light/sun may be much bigger. When I run navigation (TomTom) in winter phone stays nicely "cool".

Not sure if it could help but once i noticed the Mega too warm and discharging instead of charging, after i connected it to the notebook via usb cable!
Rebooted PC and HTC and everything luckly returned normal...

Indeed a soft reset in most cases solves this.

[Q] Defy Battery Drain

My Motorola Defy MB525 is experiencing strange battery drains. It usually drains itself regardless of usage or power state. Even in a shut down state, the battery still continues to discharge. The strangest of all is that after each charge I'm able to use the device for about 36 - 40 hours, regardless of none, low, mild or heavy usage. For about 2 years, the battery lasted around 3 - 7 days.
At first I though, it was the battery. However, after I've purchased a new original Motorola battery, the issue still persists.
In addition, the first signs of this issue arose right after a CM11 change from the stock Android 2.2.2 and continued even after I've reinstalled the Android available .SRT file over RDS Lite for the 2.2.2 version.
I've tried different suggestions and tutorials (for example - CPU Deep Sleep, WiFi power management, Baseband Change, etc.) available on the forum, but without any use.
Thus, my only question :
Even tough the device works without any major glitches, as expected from such a device. Does the above mentioned issue relate to a Motherboard or Power Management/State Chip failure?
Btw...I've took the device apart to check if there are any signs of shorted elements or short-outs. Sadly, nothing of sort.
Any help and/or suggestion would be appreciated.

Hi, maybe try another CM11 nightly or another custom ROM to see if the same problem persists?

this [http://forum.xda-developers.com/showthread.php?t=1778492 thread] goes in-deep on battery problems, but, knowing a lot about electronics, I think in your case is just that inside the phone, there is a small switching-mode power supply, and it have a (fairly) large capacitor that can leak some current. When capacitors age they became more of a resistor... and that's why most of modern electronics break up. I would blame hardware in this case.
