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.
backlight problem
hello, lately I have a problem with my PPC i-mate MDA Pro with wm 6.1 v2 rom by capante for universal, the problem is that the backlight often does not turn, the screen remains off to the lowest level of light, please who can give me a hand for resolve this problem?

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.

well try hard reset or try new rom...
hi, i've got a problem with my vox, it cuts out completely very often. all power is lost, it is not just a shutdown. i did get it very slightly wet, and it seems this problem has developed since that happened. do you think this would be solved by getting a new battery? i came to this concliusion because there are now problems when it is plugged in, and i think the power runs through the battery when it is plugged in because it doesn't turn on without the battery in. the fault seems to happen when there is a high power drain: if i put wifi in then it dies after about a minute, and sometimes it will dies as i pick up a calll or part way through one. usually i am able to listen to music through headphones using tcpmp, but normally this will die after 40 minutes or so. the battery life as a whole is terrible, with about 2 hours of using the battery draining it, and the battery is about 2 years old so i guess it could be dead? i'm trying to decide whether to buy a new one ( probably the bulky 2200mah) or give up on a phone which is on its way out (no loudspeaker-i use vibrate). so yeah, is this the battery or the motherboard?
thanks
I would say it's the battery. I had the same problem with two batteries before.
i guess it is the battery at fault.
I've had the same problem and it was rectified by a battery change.
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.

maybe you guys should read this.

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.
OK, so I've had my SM-P900 for about year now.
Suddenly just this week I am noticing my battery is draining considerably faster than usual and is also taking longer to charge. I was using a custom rom but have now switched back to the default 5.02 version that I installed via Kies.
So after a year do I really need to purchase a new battery?
I keep most everything off all the time and really haven't changed anything or how I use it in quite a few months so was wondering if I actually have to break down and purchase a new battery already.
Cheers
Read the threat : Flickering screen to see how to adjust the tip of battery cable closer in order to make better contact before replace a new battery, within one year the battery should still be good.
If you see the same thing with new battery, probably the battery connector has cracked solder joints and needs to be re soldered, common problem of Samsung tablets, not just only this model.
Lithium-Ion batteries generally last between 300-500 full charge cycles before they start losing power. A year is.. way too soon.
Does it also take longer to charge when the device is turned off completely?
In general a drain increase is caused by a software issue, mobile data or a bug. (or heat/cold.) (The difference between mobile data on and off with a 4G connection is 100-0% in deep sleep in 2 days with LTE, and 80 days in airplane mode.)
Signs of a dying battery include random discharges (it suddenly loses 30-70%, it's at 100 when you unplug and suddenly drops to 30%, or it's dead, you plug it in and turn it back on and it suddenly has 50% charge), random reboots and the device just not turning on at all for no apparent reason.
While it'll loose capacity eventually, that usually doesn't negatively affect the charging speed. (If anything it charges faster because it reaches 100% sooner.)
So assuming that I have a dead battery, is there a good replacement battery out there?
I have tried replacement batteries in the past and have found only subpar batteries on the market.
I bought a new battery on Amazon : 26$
This one is an original battery so at this price you should order one.
And about flickering issue, yes you should resolder connectors or changing the battery might solve this issue too (it worked for me)
Yesterday, I noticed my phone (a OnePlus One) was warmer than normal and the battery was draining more quickly than normal, I didn’t think much of it at the time as I was in an area with poor signal. I charged my phone in the afternoon and when I checked it that evening it was still warmer than normal, even considering it had been on the charger. I turned it off and was when it got weird, my phone stayed abnormally warm for nearly 8hrs, even with it completely shutdown. When it was finally cool I tried turning it back on, nothing. I plugged it in and saw ( https://i.ytimg.com/vi/sfdnYFZOKEg/maxresdefault.jpg ). It seems to me like something is shorted and was draining the battery even while the phone was shutdown.
I’m not sure what caused this. But I happen to have some spare parts, so I was thinking of replacing the battery and charging circuit, but wanted to know if there was something else I should do? I am a little concerned about the battery causing more damage so I have left it unplugged.
EDIT: SOLVED!
I figured it out. The issue was actually the vibration motor, I guess it shorted out, I noticed it was the part that was actually getting hot. I had a spare flex cable (which includes the vibration motor) so I replaced it, everything seems fine now.
