[AT&T, Rogers HTC One X, Telstra One XL] Hydromea:
Hi everyone.

Recently, in the past 2-3 months, I've had MAJOR problems with my battery, i.e.. unreasonable battery drain.

I used to get very decent battery life with my HTC One X, especially when using Sense ICS ROMs.

Since early this year, however, I've experiences severe battery problems.

The most troubling thing however, is the battery drain with Airplane Mode ON. It used to be (and with every other phone I've owned), if Airplane Mode was ON, battery drain was VERY low, even when playing music or something. And in deep sleep, there should be very very little battery drain.

However now, even when turning Airplane Mode ON, the battery still drains considerably – like 0.75 - 1 % an hour. And this is with the phone in deep sleep (I checked).

And with Airplane Mode OFF, the battery drain is really bad. I get great LTE/HSPA+ coverage in my house, usually a full 3/4 bars. But if I go to sleep with the phone at 80% battery, in 8 hours it will have dropped to at least 65% (Sense ROM with no apps installed).

PICTURES!

I ATTACHED SOME PICTURES

The first 3 pictures are old, with reasonable battery drain. These are with lots of apps installed.

The last 4 pictures are new, with bad battery drain. These are with NO apps installed.

As you can see, in the old pictures, with Airplane Mode ON, there is VERY little battery drain, both on Sense and AOSP ROMs. And even with Airplane Mode OFF, battery drain is much less on older pictures.

Compare for yourself.

And let me say that this problem is apparent in ALL ROMs, ALL configurations, ALL setups, ALL RUUs, ALL radios, etc... You get the point.

Actually, the majority of the 'testing' that I've done has been with fresh, clean ROM installs. Either AOSP ROMs with only Gapps installed, or Sense ROMs with NO third-party apps installed, and only Google Account signed-in.

Some configurations I've tried:

1.73 RUU, stock, no apps installed

2.20 RUU, stock, no apps installed

3.18 RUU, stock, no apps installed

Custom Sense JB ROMs, stock, no apps installed

ALL AOSP-based ROMs, stock, no apps installed

ETC...

Currently, I have no idea how to solve this problem, and am very sure that it did not exist in the past (started a few months ago). I've done nearly everything I can, even tried changing the outlet I use to charge my phone. And yes, I use the default, included white HTC charger.

My only option I see is to pack the phone up and return it to HTC under warranty and have them replace the battery. There is no water damage BTW (I checked the strip inside the SIM tray). And virtually now physical damage to the device.

This HOX is my 3rd replacement, the original was bought on May 6.

Does the warranty end 1 year after the original device purchase, or the purchase of the final device? ( I got the third one some time in June ).

But just to be safe, I need to ship it back to the before next Monday.

And lastly, I have:

S-OFF, bootloader unlock, SuperCID

In order to return the phone, I have RUU'd to 3.18 (so it looks authentic), and I will probably relock the bootloader, but leave it S-OFF.

I know you can modify the text in the bootloader to make it appear FULLY unmodified, so I might do that also.

SOOOOOO....

Any advice, precautions, etc? Especially for sending it to HTC?

Insurance, how to deal with HTC, how to convince them to replace my battery?

Any advice as to what might be butchering my battery? Seems that since I've tried virtually every software option, the hardware is the problem...

HOWEVER, could S-OFF be the problem? I S-OFF'd the device around the same time that I started having battery troubles, so could that SOMEHOW be the culprit? I don't know...

Is my battery actually looks bad, or is my perception just really screwed up? :(

Help? Please?
