I purchased an unlocked Treo 750 off ebay the other day, I received it in the mail yesterday. THe battery indicator says 0%full and has the exclamation mark on it. It's been like this since yesterday and I've charged it overnight. I'm sure the battery has charge because if it was at 0 it would have died through the night and I've upgraded it to Windows Mobile 6. I"m trying to put 6.1 on there but the PC way won't let me because it thinks the battery is below 50% and i tried the bypass through the bootloader but it says the file is corrupted after 7%. Anway, anybody know how i can fix this battery indicator problem? I've tried installing other battery utilities but they all read 0%!
I have the same problem
I got a refurb 750 last week at the AT&T service center as a warranty replacement. The first few days I noticed that when the phone was plugged in to charge, sometimes it would go up to 100% and seem to discharge normally. Other times it would appear to discharge really quickly and when I would plug it in the charge % would keep going down. Finally last night it went down to 0% even when it was plugged in and it gave me warnings and finally powered off. I have an extra battery (OEM) and extra charger so I put in a battery that I know was 100% charged and it still showed 0%, but this time it never gave warning notifications and it never turned off. Now the indicator just stays at 0% with either battery whether it is plugged into a charger or not. I did a hard-reset just to see if maybe something I installed is interfering with the indicator but even after that it still shows 0% with either battery. It works fine and I'm guessing it will turn off at some point when the battery actually dies, but this is just
Had the same problem
hi,
The problem is the battery.
I had the same problem with my treo after purchasing it from eBay... (I wonder if it's the same store)
I asked the seller to send another battery and he did, now it's OK.
My advice to you is to contact the seller, if you haven't given him a feedback, don't do it until you get a new battery from him.
Good Luck
yeah, i believe it's the battery also. The battery it came with was a 1600mAh and I found out the phone shipped with a 1200mAh. I ordered my own though...only 8 bux...should be here in a day or two
Solution found!
The solution to my problem was the battery. Like I stated in my previous post....the phone came with a 1600mAh battery when i bought it from ebay. The ATT 750 shipped with a 1200mAh battery and the 1600mAh was made for the 755 and another model i don't recall. Once I placed the 1200mAh battery in the phone, it showed the correct percentage and is charging with the battery light on (which wasn't happening before). So I'm not sure if there is different circuitry in these two batteries that caused the conflict but my problem seems to be solved.
Seems I fixed mine. I had put an extended battery on this guy, and it would never change in battery level. I would have to reboot the phone to get it to register the new power level.
Discharge your phone to 0% until it shuts off. Try to turn the phone on several times to make sure its discharged (should shut off immediately). Charge the phone to 100% without unplugging it (will take a while, do it over night).
Today my % seems to be registering and no need to reboot the phone to change it. HTC tech support claimed they had nothing to do with the battery manufacturing so they wont help you.
if you reboot your phone how accurate is it to the actual battery meter showing you the percentage? I am at 6 percent left on my phone in hopes of discharging it and than charging it full to get mine to work

It will still probably jump down about 10% but it will sit there for a LONG time until the system is actually to that percent. My recommendation is dont reboot the phone if you want to keep accurate %. The rebooted value I dont believe indicates actual battery life remaining. There is a communication problem between the phone and the battery - HTC confirmed this is going to be patched (on the phone with them last night).
Hi,
I bought a new battery for my Desire (LeeDroid 2.4.1), it should be an original HTC battery and it looks like this. And it seems to have a good capacity.
But i has a VERY strange behavior:
I put it into my Desire and put it on the original charger while it was off. I wait until the green led came. then power on, charger off.
the desire said: 94% not 100%. So I put it on the charger, again. % raises, with 44mA (Battery Monitor Widget and other battery monitor apps showing this).
after some time 100% but still 44mA charging current!?
putting charger off: still 44mA charging current!?!?
So, I used my Desire. from 100% to 0%: the whole time: 44mA charging! no discharge current, charge!
and the whole time: voltage is stable at 3923mV no decrease
And another strange thing:
using a video player, % and mAh in Battery Monitor decreases (this is ok), and after player and screen off: the % and mAh level increases!
so my actual battery log without a charger:
15%
15%
15%

a) any idea what to make with this battery
b) any idea what this is about?
BTW: Can anybody tell me: What part is responsable for the different values? Does the battery (with its charging logic?) tell them to the desire? Or did the Desire estimate them from voltage or so?
battery voltage
mAh level
charging/uncharging current
temperature
I guess you're not the only one who has a weird battery ;-) .
Sometimes my battery is charging and charging and charging until 99% but not until 100 and the LED does not get green, it stays red. Then, sometimes it gets green and 100%. But it does not stop at 94% as you said.
And often the battery discharges and suddenly it gets 1 to 5 % more. Sometimes at the status of 60% or as you have it between 10 and 15 or even between 30 and 35.
I really do not understand this battery behavior but I have to say that I also bought a second battery. The original battery did not behave like that.
Oh and I also have a custom rom, but I also had this behavior with the original rom.
Sorry that I could not help you but if someone knows something about it, that would be very nice.

Did you happen to erase the battery calibration file before booting with the new battery? You can do it from the recovery menu (clockwork) or using an app (com.nema.batterycalibration)
If you don't do this, the OS assumes you did not change batteries and will be confused when the battery does not reach certain thresholds as expected (100% going up, 15% going down, 5% going down, 0% going down).
Also voltage does not equal total charge. Voltage is influenced by temperature, charging stage and speed or discharging stage and speed, also time between the charging and discharging events.
Just fix the calibration file, after you charge the battery to 100% (power off, replug charger to be sure to tap it off) and do a full discharge and recharge cycle.
sorry, forgott to mention:
after my first shock I delete it in recovery menu. No change.
And I cannot believe this is a battery stats issue: I have two old batteries, one original and one third party. I can swap them and every time I got a reasonable current value while charging and during using it. Only the new one has this error.

But it is nearly impossible that the voltage is absolut stable over a whole using period, or?
Even now (I used my older HTC battery this day) with the new one I have absolut stable:
44mAh, 3923mV
IMHO the battery tells wrong values to the desire. therefore my question: Does anyone knows which values are told by the battery logic?
stm999999999 said:

It is very possible. The cheap 3rd party batteries ICs do not report voltage and temperature correctly, just a static value to be accepted by the device.
This is why charge estimations won't work correctly. I have such a battery, the only reliable read is when it goes under 15%, and 5%. Those are real warnings, at least the battery won't flake out without notice.
I wanted to say: a stable and correct value should be impossibe - of course a faked value can be stable. But this battery should be an original HTC and no 3rd-party.
But it seemed to be the battery: I tried it with another desire (stock rom) and the same error. So I have to talk to the salesman.

Well there is a very small chance the battery was genuine but broken, otherwise I'm sorry, but the Chinese manufacturers need to be taught that smartphone batteries should be treated more like laptop batteries, use a better controller and you get better sales.
I believe genuine official batteries can only be obtained from HTC shops and official resellers.
got a replacement - same behaviour

Have you solved the problem since?
I have a HTC Desire, and replaced the battery recently with a supposidly genuine one and am getting exactly the same behaviour - 44mA and stuck on 3923mV. The phone also never reaches 100% when charging (while powered on), reaches 99% and says there with red led forever. It does show green when charging powered off though.
The battery does seem to last more than the older one so it's not a major issue - I'm just concerned at the not reaching 100% part (damaging the battery?) and the accuracy of the battery meter in android (% remaining).

no, got an envelope for reshipment.
I think about bying a battery directly from Amazon. I hope they have original parts.
Yea, thanks for the reply. I put my original battery in and it works fine so definitely a fake / broken battery. Bit pissed off as the place I bought it from swore it was genuine.

Got a similar defective battery, but the guy who sold it to me did not agree to replace it..... I think it is a dangerous battery not to be used

Hey guys I am a long time Android enthusiast. I have one of the most popular Samsung devices which is the Samsung Galaxy fit. The problem with my Samsung Galaxy Fit is the battery. Earlier before any tweaking battery used to be normal. After I installed CM7(official build). My battery started draining randomly. At first it was ignorable but then the problem became severe. From 100% it would drop to 88% in just 2 mins use and then from 88% it wud drop to 70% in another 5 mins and the entire phone would be dead in just 3 hours at best. When I would charge the phone again the battery will also be charged randomly going from 5% to 20% and then 20% to 40% all this in just 10 mins. In no less than 20 mins would my phone be 100% charged but that's fake as the battery would drain from 100% to 0% in three hours.
Following are the solutions are tried
Changed the batter,used a brand new original battery(FAIL - DID NOT WORK)
Flashed stock Rom (FAIL - PROBLEM STILL PERSISTS)
Changed Charger (FAIL)
Recharged battery on a different phone and then inserted the battery in fit (FAIL)
If anyone has any solution please let me know. I AM ALSO WILLING TO DONATE IF PROBLEM GETS SOLVED.

You could try Battery Calibrator.. The app is available on Play Store.

Hope this will help you..
1. after flashing custom ROMS, back to recovery or CWM then wipe the battery stats.
2. calibrate the battery while device is on, i ussually use Mugen Power app (install app, choose the standard battery, charge until 100% then click calibrate, after that use the device until the phone is dead then charge until 100% again while device is off).
other Calibration apps ussually have the same steps like the steps i mentioned above, so just use one app..
3. if you still having the battery drain, maybe you should go check the hardware in some technician, coz it could be the hardware that has the problems.
Hello,
I have bought an replacement OnePlus battery (the red ones) it looked identical to original one, the only difference was that it had an extra sticker hologram like. The battery was replaced at a service center (after I have ordered it my self, it also comes with 1year warranty).
The issue started the first time I changed the battery. It came charged at first to 55%, I used it until like 35% and then I left it to charge. Charging stopped at 90%. Accubattey measures a capacity of 3050 mah. However the voltage was at 4.280V and at this point it will not accept any more current (charging current drops to 0mA).
When normally charging it with the original charger it draws the usual 2 ~ 2.1 amps. Then I drained it to 0. Now it charges to 95~97%.
My questions are. Is the voltage correct for stopping the charging ? Should it not go 4.35V?
Do you think that repeted discharge to 0 cycles my fix this issue?
Should I consider using my warranty, for the battery and request a new one? Also on this topic. On the supplyer site it states that 5 cycles should be performed to calibrate the battery.
Did anyone else experienced this?
Thanks
calibrate your battery and see if you could find any change,if not, which rom/kernel are you on?
Well I am running 25 Dec CM 13 by sultan XDA, I did not flash a new ROM after the battery replacement.
What steps would you suggest for calibrating my battery ?
I was thinking of dischargeing it to 0 then trying to start it until I get no response from the device. I mean not even show the boot screen. Then leaving it like this for two hours. And then retry to start it, just to make sure the battery is all the way discharged. Then plug it in and leave it to charge over night and see what happens. And if it's still not 100 repeat until it happens.
Thanks for the reply.
