Hello guys...
Its been a month since I rooted my Explorer, everything was fine.
I am very caring for my small pico, I charge it by switching it off, never unplug the charger untill it is fully charged, I am using using it for an year and it has never been dropped from my hand. I do respect my things, my Nokia 6600 is still 'new' and I have been using it since December 2004.
My pico stands on battery for nearly 3 days with average usage (reading ebooks, music, some internet, calls and messages).
And for 4-5 days without internet connectivity.
Date: 1-May-2013, 1700hrs.
My battery was down, I switched my mobile off, plugged it to the Original AC charger which I got from the Explorer box and waited, It takes 2.5 to 3 hrs for full charge, I unplugged it from the charger, switched it ON and kept it aside.
After nearly an hour, I took up my mobile and shocked, battery indicator was not fully Green (i.e. first unit of battery indicator was finished).
I then opened an app called 'Android Task Manager Pro' and it was showing 'Battery : 76 %'.
I cannot understand the cause, I haven't installed any new app or so.
Without any time, I just switched it OFF, took out my SIM, reinserted the battery, switched it ON, switched it OFF and kept it in Cupboard for 2 days.
Date: 3-May-2013, 1930hrs.
Took out my mobile from Cupboard, switched it ON, only 2% of the battery was remaining.
Plugged it to the charger, and after just 20 minutes I unplugged it from the charger (it was the first time I have unplugged it without fully charging)
Saw the battery %, it was 23%.
I then switched it OFF, took out my battery, and put it into my Sister's htc Explorer.
In her mobile, the battery shown : 46 % and it was draining rapidly, 33% in 5min standby.
I took out my battery and gave it to my neighbour to keep it refrigerated for the night (I usually refrigerate my Nokia 6600's battery, as it was good practise to do so for Li Ion batteries, my Nokia 6600 is still performing with the preloaded battery from 2004).
Date: 4-May-2013, 0730hrs,
I took my battery (very cool), kept it in middle of paper rack to de-moisturize it, after 5 minutes, kept it in open atmosphere for a minute.
Took the battery, noticed it finely and found a RED mark on it.
Is my battery dead??, if yes then cannot believe it, it was doing well, it has not become fat.
Please, help me friends is there any way to cure it back???
Please, if cannot be cured, please provide link for buying a nice battery [LAST PRIORITY].
i think your device pin which is connected through battery is getting some thing wrong..and thats why your killing itself very faster....take off battery from device...then you have to change or solder from device circuit..it will surely solve the problem...

Here is the snap of my battery
This red thingy I believe is moisture 'sensor' which is normal to be red, your battery was in the fridge. You can give it a try now, if it has no moisture in it, but I'd wait for couple of more days. Also you should know, this is low end phone and it's battery is not as good as old nokia, maybe some ice was inside, this should kill it.
Now I have a suggestion, try with battery from another explorer(as you have one close) and check out, how this other battery is doing on your phone, if it's also bad........ new battery won't change things, also this may indicate some software issue, check thing out with better battery stats, or with GSam battery monitor, if there is nothing wrong with software, you can try charging the phone from usb, maybe your charger is fu&*ed up.

Maybe this depends on the batterys but mine was having that problem of going dead at higher and higher % it started at 10 than 30 then 50 and up to 70 I think.
I've tested all the solutions in the wiki (yes the freezer too ) but with no improvements, then I did the opposite, instead of draining the battery fast I drained the battery slowly and when the Universal shuted off I pluged it to the electricity until it boots ok and the cpu returned to 0/1%, then take it from electric power again and wait until it goes dead again and did this over and over again until I reached the minimum battery of 9% i think. Great improvement since I was already looking for battery replacements... Then I charged it over night.
Conclusion I have the Universal alive for 3 consecutive days (and nights) now at 52% waiting to check when it dies again
By draining the battery slowly I mean no light in the screen, no running programs and universal in closed state, flight mode and just one thing to check if it was alive or not, play some music in WMP in repeat mode, when it stoped playing it was time to have a litte more eletric juice until I could boot it up and start the music playing again.
When I have the final results -> when the universal goes down I will post the solution in the wiki
Again this may depend on the batterys but since there are so many people buying new ones you maybe want to try this solution too.
Oh and by the way I solved an "other" problem while trying to solve this...
Besides the tests on the battery like freezing it over night, taking the power level pin etc, I've started to think it was a problem from the rom so I cleaned the Universal doing that "task 28" thing and the result was solving the problem that I was having with the battery status (now home screen plus plus) it was not getting the cpu using percentage when in the past it did. Now with the cleaning reg whatever It is showing again the cpu using %
I don't know if you use this but it has a cool functionality, posting the cpu using % at the top bar of your universal can tell you how much the universal is working all the time, enabling you to notice when it is working when it shouldn't, normally some stupid background program that didn't go off...
hi there. I have two same unis, and three batteries. two standard, one big capacity 3200mAh (personally I dont believe it have such capacity, it is some china crap). but all three had that issue (uni shut down when capacity still showing more as 30% or more %). tried to deplete the battery completely (when it wont boot, I put device to bootloader mode and wait untill died completelly). now it show again 0% on all three batteries. I dont want to say, that your method is bad . no, I am just a lucky one, where the "wiki" methods worked correctly. and I think it is also important sometime charge the battery completelly, not only for couple of minutes, but until you see green light. when you deplete the battery completelly to zero (it is never zero, electronics integrated on the batter doesnt allow that) charging to full take much more time as before.
powerdetect
one more thing, you can test, how much capacity your battery have. it is simple utility called power detect. you can find it in THIS thread or as attached file. just copy to device and run. the test will suspend itself after one hour, so set all settings as needed. it will automatically create file, where you can find all important information. before you use it first time, charge your battery to full.
Thank you for the reply, My battery still dies at 30% but no more at 70% and 50% and it lasts 3 days/nights in a row.
I tried the boot loader mode but it seemed it had a timeout, instead of dying from battery losse it died from some kind of time out :/ because I was still capable of juicing some more battery if i went again to boot loader...
I will check that app, thnks again
wat i did..
well my battery used to shut off at 95 above present...wat i did was drain the battery with a 12 volt motor, took me a complete day for it to discharge, then i put it in the freezer, was suppose to put it for one night but i actually forgot bout me putting the battery in the freezer n i remembered after 2 days. then i charged it which also took around 18 hours to charge now my batter shouts itself at 70% n i can listen to music for 1.5 hours. which is a lot from a battery which was shutting at 95%
Hi there
I just want to share with you how I fixed my battery. The problem I had was that my HTC Desire HD did not recharged the battery. Every time I plugged the charger, the smartphone flickered orange, green, orange, green, orange, green and then stopped charging.
What a I did was to place the battery into the freezer for 3 days. Then took it out and waited until its temperature came to normal.
When I tryed to charge it again, the Desire HD flickerd again the same combination but after 5 seconds it started to charge regulary
may it a good trial ?
but i wonder that does your battery work normal after you charged it ?and how does it performance
I have one battery just bought and used for 3 months but I forgot and put it in over discharge then its capacity drop from 1000mAh to just only 500mAh. I just though some of its's cell became death
Well, after 24 hours since I unplugged the charger it still keeps 29% of battery.
Of these 24 hours, the phone keep flight mode 8 hours (I always use when I go to bed), and the other 16 it has been working with Wifi always on, 2G and sync on.
I am not a very intensive user as you can guess, but for me, it is more than enough after thinking that battery was dead. Anyway, I already order a genuine replacement battery at eBay (I didn't think freezing the battery could recover it) so I just will keep the old one until I get the new one

Wow, never heard of this option to revive a battery.But good to know and I maybee will need it one day, so thanks ;D
Good tip for when you're stuck without a phone! Sometimes also works on chargers that die (put in a bag, freeze for 20 minutes, try again), and hard drives (got a 15 year old HDD working long enough to get some data off it).
PS, keep the HDD in the bag once out of the freezer, condensation forms on the bag and not the HDD.
Does anyone know what to do when battery says its 0% charged even after it has been fully chaged(the charge led is solid)
I have this weird problem with 2000 mA replacement batteries for the hx4700 (The original one is 1800 mA).
The thing is that both replacement batteries now report 0% to the device even after they have been charged and the amber light comes solid, indicating that the battery is charged.
First battery "died" few monts ago about a week after I charged it for the first time, that happened the day after when I took it out so I can charge the old original one, the new battery had 75% left, so I didn't want to charge that one. The next day after I used up the old battery, (which is still working fine, except that it keeps dying on around 20% power left for years now, because the voltage drops under 3.5V) I replaced it with that new battery which was supposed to have 75% of power left, but it reported 0% so the device died, so I charged it over night, the amber light was solid, but the pocket pc went with critical battery level and CF/SD card removal bull**** and turned off shortly after that, since the circuit that is in the battery reports 0%, no matter what I do, I tried cleaning contacts, tightening the cover, took the battery apart and there was no visible damage and nothing. Then I throught it must be because I accidentaly dropped the battery on the floor (it didn't sound very good), so I just out that one aside and used the another battery.
I have used the another for about a month, charged it only when the battery was actually under 20% or dead, didn't even take it out. Today the battery reported 0% just like that another one and it was fully charged. Also I'm sure its the battery not the pocket pc, I have two hx4700 the old one I have been using for 6 years and the new one that I have just assembled with parts I bought from ipaq repair a month ago, the old battery still works fine and its reporting the charge correctly in both devices and the new ones are both charged, but reporting 0%.
I worked around this problem, by disabling this driver in registry HKLM\Drivers\BuiltIn\BatteryIF\Dll
I chaged the value from "battery.dll" to "battery.dllx" so the driver doesn't work and the battery levels are unknown to the device.
The battery runs fine for hours, like it did before, meaning there is nothing wrong with the battery cells, but with the little circuit, that is inside of the battery and that its annoying, because I don't know the level, can't tell when my ipaq will shut off.
Has this ever happened to anyone? Is there any way to get the battery to work again, without disabling the driver? Should I try replacing the cells of original battery with good cells from those bad batteries? I'm really frustrated how the original battery doesn't have the problem after many years of usage and the replacements have issues after few weeks!
Hey guys, i have reacently bought new htc desire 500, and i recently noticed (at the nex day) that when i pull my phone from charging (green light indicates that its fully charged) the phone imediately goes from 100% to 99%, and in two hours goes to 80 even if i do nothing... This morning i just read some newsfeed over wifi... In 20mins it wen off to 94%. The phone is brand new, not rooted stock firmware. I have sent it to repair center they just changed the charger. And the same issue persists. I have tried to calibrate the battery, tried and charging in other ways... But its just the same. My old htc rhyme stayed at 100% for hours if i didnt use it. And after university time (6h a day) it just depleated (with games and etc) to 60. But i had plenty of time to go to internet and chat whole day with couple of quite long calls. Sorry ofcourse for crapy language, hope there is some sort of repairs, caus i dont want to give my phone again for two weeks again...
think i found what happened
ok guys and again me i have gotten home from university now, and putted phone to charge. it was showing me that it has began to charge from 7% and ok, then i just pulled out the charger pulled out battery (charger cable is in phone) then i putted charger back and then battery, and pressed one time the on/off (1sec) then phone turned on (not completely) and showed me that battery is charging, from 73%. (the turning on, the phone wast not complete, it started to show only battery that shes charging) so i think there is some problem with calibration of battery, so we need to do is give it a quite good kick, with charger and non official charging mods. (pulling out battery while it charges and etc...)
Hi everyone,
I have a Leagoo T5c with a more-or-less 3,000 mAh non-removable battery, and for the past few month, battery life has been somewhat erratic. The phone would go from, say, 50% to 10% battery in no time, and I would get the low battery warning, but at other times it could hold at around 45% for a while before really going down for good.
Last night around 8pm my time, the phone went completely dead while the battery indicator in the task bar said I still had about 65% left.
I tried what's described here and there as battery calibration: I left the phone turned off, patiently waited a couple hours (yes, yes, that long) for the battery to reach 100%, then left the phone off for another hour before turning it on.
In a matter of minutes doing nothing more than checking my Twitter TL, the battery went from 100% to around 85%, and was still there went I tucked in for the night, leaving the phone in Airplane mode as I always do at night.
This morning, I turned Airplane mode off and the battery said it still had 82%, which means minimal drain during the night, with all radio off.
Just a few minutes ago, the phone went completely dead after the low battery warning, and the battery held less than 10% charge.
WiFi is off, cellular reception is very good where I live, and anyway, I don't see how LTE could kill 70% of the battery charge in less than half an hour, even if reception was spotty, which it's not.
I plugged the phone into the charger it came with, put it in Airplane mode again, and it went from 10% to 70% just now in less than 30 minutes.
I know for a fact that fast charge isn't supported on this phone, at least not with the OEM charger, plus it has micro-USB, so I doubt the charger can feed it that much juice in so little time.
The charger itself seems to work fine: It never gets hot while charging, not the Leagoo, nor my old iPhone 6, since I use it for both devices.
So, long story short, is there a way or tool to ***really*** know what state that battery is in? I've tried both DevCheck and CPU-Z, and both say that the battery is in good health, and still retains its nominal capacity of more or less 3,000 mAh, but I have my doubts about that.
I think the battery capacity is reduced somewhat, and I need to know by how much.
Any help and input would be much appreciated!
I must add that I flashed a stock ROM on this phone (yeah, again...) a few days ago, so maybe it's the ART cache being replenished that's causing my battery issues, but still, the problem is so inconsistant that I don't know anything anymore...
I had to flash the stock ROM again after trying (again...) to root the device (successful, but doesn't bring anything of value) and finding it barely responsive.
I'm gonna leave the phone as is, ROM-wise, but my battery is still a matter of concern, because it dies on me at the 60-65% mark more often than not, though two days ago I let it drop to 30% without the phone shutting down.
Like I said, it comes and goes. I really need to know if that battery still retains its nominal capacity or not. Any help in that regard would be most welcome...
