Backlight Problem

I have a new issue with my backlight. I didn't really see anything scanning a search on backlight so I'm hoping someone has seen this before and can help.
I just got a new 3200mah battery. Ever since I started using it, after turning off the device, I go back to it, press the power button or backlight button and while the screen itself comes on, the backlight does not. No light at all. I also often find that the screen is on already when I open the phone (which might explain why my battery is sometimes finding itself dead in a matter of a couple hours). I change the backlight setting to be the second tick on the scale (lowest light level) and turn the phone off again and then if I go back to it 5 mins later it's gone back to the first tick (off) on its own. However, turning on the phone right after I turn it off and it stays at the first tick. I've not be able to figure out why it keeps resetting itself to off.
Please, if you are familiar with this can you offer some direction? I'm using Helmi's WM6
Thanks

I never encountered this problem.. have you tried to keep pressed the power button and verify that backlight turns on? Or is a settings problem (backlight settings turn itself automatically to zero)?

It 0's itself. I can turn it back on again with a little difficulty (as it's hard to see the screen without the backlight).

really weird ...
have you try back to use the original battery? just for check is it something wrong with your 3200?
if it still ... (also for all problem that i can not solve) ... backup all data and ... hard reset!!

Backlight fixed with new flash...battery problem now
Ok, I reflashed with the Business rom and the backlight issue is gone. However, I have another issue now. When I charge it overnight, in the morning the power light is green, but if the Universal is off when it goes green it seems to hang and I have to reset. If the Universal is on, it responds fine. However, in both cases, when I unplug the power from the Universal, the light stays solid green and requires a reset to show the true battery status.
Also in both cases, after this overnight charge, the battery dies within an hour or two, the power level going down to 4%. As a result, I end up charging it at work (with a different charger) until it gets to 100%. I haven't tried leaving it to charge longer. But once charged on my work charger it seems to discharge properly without dying in an hour or two.
I'm very perplexed by this situation. Is this a battery problem, charger problem, phone problem? The battery, as I mentioned earlier, is a brand new 3200mah. Should I return for an exchange? I'm looking for any comments at this point.

Hi,
The locking up could be down to the overclocking/stepping built-in to some of the newer Roms. Some Uni's over/underclock quite happily some do not. Mine will happily overclock but locks up when stepping back down.
As far as the battery/charge issue it could be the battery itself or the charger, when charging at work are you using USB to charge and mains at home? It could be that the mains charger is charging too quickly for the battery to hold the charge and the device reads the battery as 100% and thus stops charging it, whereas the USB trickle charge is slower and thus the charge remains for longer.
Do you have another battery to test?
It could simply be the battery, there have been a lot of reports of Ebay batterys not reporting and holding charge correctly.
Cheers,
Beasty

Yes it is an eBay battery. The charger at work is a "main", however, not an original "main", but its also an eBay special. The original "main" at home was designed for UK but I'm in Canada so there's a voltage difference but within the tolerance indicated on it's input definitions.
I'm however inclined to agree with the "trickle charge" comment. It could be charging more slowly. And I have not left it to see if the charge light will lock on green after the charge. I'll try that during the day and charge overnight with the work charger to see if I get the same result.
I'm still open to more comments.

when you charge your 3.200 next time, try this ... on backlight uncheck turn off backlight on battery power. I hope its work for you too.

I had the same prob with a ROM used on the past, backlight movet to lowest or even off randomly.
I corrected changing to another ROM.

PHONE DOES CHARGE WITH CWM (just not showing LED)?

MODS PLEASE DELETE THIS IF YOU WANT ONCE VERIFIED
Basically i had 90 percent BAttery
I switched off the phone, Took out the battery to be sure it is completely turned off.
Plugged in my charger (im charging via PC at the moment, will test with wall charger later)
The LED Came on and then went out after 2 seconds
After ten minutes i took out the battery again and reinserted and powered on
My battery was 100 PERCENT
use battery indicator from market to check your current level or you can check it using *#*#4636#*#* and clicking battery information
Can you please check this. and post here ASAP.
Make sure your battery isnt fully charged (between 20 and 80 percent ideal), Turn off completely (pull the battery out and reinsert if you want to be sure)
Plug in your charger now
After 15 minutes
Take out battery and reinsert.
POWER ON
What is you battery now?
please post your before and after percentage here. THANKS

Mine too.
After CMW and S-Off it is not charging, same behavior. And my battery if fully discharged, which means I bricked my device since I just can't turn it on nor charge it...
:/

You can either let a friend charge your battery for you in his phone
Or
You can get a usb cable, any kind really, chop off the end that goes into the phone. There will be 4 wires exposed, you only need the red and black ones, pay no attention to the green or white wires or whatever color they are. Connect the exposed wire to the battery (to part that touches the prongs on the phone) and it will charge. All you have to do is find out on the web which of the 4 slots on the battery do what, and connect the positive (red) cable to the positive slot on the battery, and the black cable to the neg part of the battery.

In the worst case,you could charge your battery outside the phone with a power supply...
Not an easy way,especially if you're going on vacation...But it's a good thing to be aware from this!
Edit: Durps,you killed me!

my phone charge while off i see alot of people are suffering from this but mine still charge while off my led is on

The issue seems to be fixed with the official cwm recovery flashed from within rom manager.
...at least for me.

I bricked!!
I bricked...
My battery was almost 1%, i removed the battery, and now I am f***ed...
None of my friend use HTC Sensation. and i m totally tensed what should i do...

walk into a phone shop, ask them if u can charge your battery for 10 mins in one of their phones.
Say something about software crash blah blah, they usually dont care at all, and will let you.
PS to confirm is version v4.0.1.5 the good one? ie will let you use/charge your phone in the "normal" way?

update your versions of rom manager ...the dev updated the recovery and now it does charge

Just install the new CWM version 4.0.1.5 from ROM Manager to fix this (HUGE) bug

[Q] Is my phone dead? :(

1. The phone won't turn on
2. The charging indicator doesn't light up when I try to charge the battery.
3. One of the sensors on the top left turns dim red in color when I connect the charging cable
4. I can't hard reset either
thanks

Did the battery die all the way? Or did you flash a radio without checking the md5? If its a borked radio install say hello to a 500 dollar paper weight if its the battery your gonna have to charge it in another phone cause I'm not sure if cwm 5.0.2.7 has powered off charging

Yes we need a couple of info first. Also we need every information we can get in the last events before the phone got bricked. Like what did you do? what ROM? What's the status of the phone? Battery?
The more the details the better we could assist you.

Sounds like when my first Mytouch 3g broke, it would turn on the first couple of times going into a bootlope at the HBoot. It also didnt respond to charging or any other battery i tried.

Thanks for the reply strapped. I haven't flashed a radio. I did flash the virtuous infinity rom though. I'm not certain if that affected the radio. I did, however, let my battery die all the way. Do you know why one the sensors on the top left corner turns dim red when I connect the charging cable?

Oh crap the battery die all the way problem
I think your battery is dead.s
Saw dozens of problems like this on the my previous device's forum.
Li Ion batteries have this fuse inside it in which it trips off when the battery gets discharged to a certain voltage. If it does your battery goes into a suicide mode in order to protect the phone.
basically the best thing to take good care of your battery is not let it drain lower than 40% and not fully charge it to 90%.
discharging it too low drains it's lifespan drastically. While charging it too high also drains it's lifespan.
Over-discharging Lithium-ion
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage. To minimize the current flow for the protection circuit before the battery is sold, advanced Li-ion packs feature a sleep mode that disables the protection circuit until activated by a brief charge or discharge. Once engaged, the battery remains operational and the on state can no longer be switched back to the standby mode.
Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. If recharged, the cells might become unstable, causing excessive heat or showing other anomalies. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.

Cheers guys. Here's every bit of information I can recollect
A few days ago I created a nandroid backup and formatted my sd card via the PC.
I flashed the latest version of CWM recovery
I flashed the virtuous infinity rom 1.33 alpha v3 and then flashed the 1.35 beta 1 update.
Then i copied some music on to the SD card and installed a couple of apps.... nothing out of the ordinary.
The phone worked fine the last couple of days but I don't remember letting the battery die all the way. I should add that I have a dodgy battery; a couple of months ago my dear girlfriend spilled her drink and beer went in to back of my phone... since then the keyboard doesn't work (some keys work but its basically dead) and the battery has been affected as well since it now only lasts 3-4 hours after a full charge....but this issue can't have caused the problem I'm now having because the dead keyboard and dodgy battery have been around for a few months...
Last night, however, I think I let the battery die all the way and at some point, when I tried to turn it on, the phone vibrated as it does when you hold the power button, however, the screen didn't turn on. Since then, nothing has changed. When I connect the phone to the PC, it makes a couple of "connection" noises but I can't access the SD card or contents.

by saying latest CWM is it the 6.0 touch based CWM by chance?

sorry mate, i meant 5..0.2.7.

That's the CWM I'm using so it's safe. I'm also on latest VI for weeks without problem.
So it all points out to your battery.
Phone vibrating to power button means it's responding perfectly. Not sure about the light on the sensor only htc technician can tell.
But what I can say is if your trackpad button lights out red always then you got a brick on your hand.

Nope the trackpad isn't red so I guess that's a good sign. I've ordered a new battery and should have it later this week. Let's see if that fixes the issue. Will report back. Thanks all!

So, a new battery has arrived, however, it hasn't helped as the phone won't charge (no orange light) or turn on...... Since I live in Australia, I don't know anyone else with this phone. Is there any other way for me to revive my brick of a phone?? Thanks

Get a universal charger for your battery.
Sent from Spaceball One.

This is a rough situation. Even with my DS I've had situations where nothing would happen when I tried to restart it, in particular when I let the system run all the way down. It is as if the battery needs to have some charge for it to charge more. I have three batteries though (the stock & two Anker 1900's) so when this happens I just swap out the battery with one that I charged in the external charger, and I haven't had any real issues with them long-term. Since you bought a battery, what battery was it, and do you think it was charged when you got it, and do you have an external charger to verify that the charge is solid when you put it back in the phone? Your phone may be completely dead however, but at this point, I don't think anybody on the thread really can tell. This make sense? I don't want to say, "buy a set of Anker 1900's with an external charger" but it was cheap enough vs. the cost of the phone, and the DS does seem to be a good one overall.

Hi All,
So I got an external charger for the battery and it arrived yesterday. I then proceeded to charge the battery and hours later, no luck. The phone still doesn't turn on. When I hit the power button, one of the sensors on the top left turns red slightly, shortly after which the phone vibrates. However, it doesn't turn on.
Where do I go from here?
Thanks

have you tried to disassemble your phone at all? you said liquid was spilled in it, could take time for corrosion to turn up. maybe a little electronic parts cleaner or rubbing alcohol may help out

Nope I haven't tried to disassemble it yet but is that the only option remaining? If yes, I might have to give it a go because this phone is now as useful to me as a brick, in its current state.

Note edge battery drain while off!

I have a Galaxy Note Edge model number n915p.05 battery drains while phone is off
When battery is unplugged from phone phone will not turn on unless plugged into original charger even if battery is at 80%
If battery is removed and then plugged in and will not drain while is off unless turned on

Hello,
Can you please elaborate issue?
-Vatsal

More in depth description of the problem
I Purchased a NOTE EDGE Used about 2 weeks ago, I was told the problem was a generic battery causing the phone to overheat, I bought A New battery which somewhat solved the overheating problem however upon using the phone even with a new battery I noticed there still is significant battery drain in a short time. Also When the phone is completely off the battery still drains at a fast rate, If plugged in the battery doesn't die but charges extremely slowly even with a rapid charger and rapid charge activated. Another Issue that I have is when I remove the battery the phone will not turn back on once its back inside unless plugged in and when I connect by usb to the computer it shows connected on the phone and on the computer but in programs such as Odin it doesn't show up unless I remove and re install the battery multiple times I've done all I can think of to fix this ( bought a new battery, tried re flashing the firmware, Shut off all unused apps and turned off all data Wi-Fi and Bluetooth, dimmed the screen, battery saver etc.. ) the phone drains regardless even when phone is completely powered down.

sounds like a PCB having a problem. Maybe the charging circuit

N.m. just googled it

After I updated to 6.0.1 update on my note edge , once the battery reaches 49% it just turns off , it doesn't turn on , while I put it for recharge the battery charge shows 49% and it turns on.
I have done 3 factory resets still the problem arise. I did factory reset to clear cache and to clear any errors in apps. This is my primary phone for work and I need to carry power bank all the time. Please assist

Time to change the battery. It is not about the percentage of the battery. It is more about that the voltage breaking. As it seems the battery can not longer hold its voltage due to battery age. When the voltage breaks, the device will automatically shut down to due low voltage

From what I notice is something is wrong, mine started to act weird earlier after I updated a latest ota firmware, before when I charge its take only maybe less then a hr to full charge, I did a factory reset now its take two hr to full charge, now monitor again

My battery went to hell also after this update and I just got a new one a few months ago

the only solution i see is to stop buying original battery replacment since it might not be the issue , rather slap a zerolemon 9000 mah battery on , it looks like a tank but at least the battery last lol.

Im still having trouble with mines too, injust dont understand why phone is draining battery while off and fast . You ciuld feel the heat off the phone while off...

Maybe you should try to get an extended battery pack? here's what i tried - so far so good! https://www.youtube.com/watch?v=i70xqUNoYVE

Honor 8 battery charges from 0 to 100% in few minutes

I changed the battery buying a new one on amazon, the problem was that when the phone was at low % it shut off sometimes at 20% sometimes at 40%. Ater changing battery i noticed that the problem disappeared for a week, but then reappeared, so i changed the charger and tested different cables but both charging and discharging are irregular, it charges to 100 in 10 minutes. So i ordered a new charging board on amazon, i changed it but the problem persists. Im desperate, i dont know what to do, sorry for my english. I thank anyone in advance who wants to help me.:crying:

could always try recalibrate your battery

I think you should change your phone's battery mate. I changed mine last week and it's as good as new now. Charges and discharges exactly how it's supposed to. My battery had similar issues before I changed it.

TRY CALIBRATION ?
1.Discharge your phone fully until it turns itself off.
2.Turn it on and let it turn off again.
3.Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4.Unplug your charger.
5.Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on the screen as well.
6.Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7.You want to repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
8.Now, install the Battery Calibration app, and before you launch it, make sure your battery is at 100 percent again, then restart.
