Desire Power off at 17%

Hey Guys,
my desire goes off at 17% battery.
I have tested battery calibration, but it doesnt help...
Hope you can help me....

Which battery calibration did you follow? The only 'real' guide is this one:

Anyway, I would not care about that shutdown-problem. If you handle it right, you can bypass this problem:

I follwed the battery calibration by Professionals from the play store...
At 100% i press calibrate, but it doesnt work so good...

On wich ROM are you?
It really depends on the rom/kernel you use i suppose.
Last month I flashed about 15 roms and always wiped battery stats and calibrated it. Then there are people that say it's because our desire/battery gets old. But i don't believe that.
With Runny Rom for example i could go as low as 1% of battery without a doubt.
I hope that the developers will look into it cause it can be annoying altough MatDrOiD said it right about the way of charging your battery.
BTW thanks MatDrOiD for the link.

I use the mildwild ROM v4.5

What do you believe in then? I hope it's not in wiping batterystats.bin, which gets wiped anyhow when battery charge goes over 90%.

Hehe, no I don't believe in that either. Actualy I have no idea what the problem might be, but when a phone gets older, it would be a process right? Not 17% from one day to another.
And if that was true it wouldn't be possible that my battery stats are back on track after flashing a new rom. It is a weird thing i think...

I´ve the same problem. Sometimes it works till 5% and sometimes it turns of with about 10%.
With the voltage level is everything fine because the Desire of a friend works till 5% with the same stats.
Wipe battery stat didn´t fix it.

Did you charge your Desire when it is on or off?
Try to charge it when its off.
I have the feeling that it has an influence on it, but I am not sure

That's the point, the solution is there but not all developers are including it in their kernel. Is their a reason for that?
I'm not a dev so it's no solution for me, or am I missing something?

Alarm rings even if the phone is turned off, if I remember correctly. Why don't you test it?

i'll test it at the weekend...

Or just when you have time: Set alarm two minutes after current time, turn the phone and you'll see what happens in two minutes.

[Q] Small battery issue

Alright so I'm charging my phone (which was at 30%) and I do a quick reset, when it boots back up its at 100% 0_o, this happens pretty often. It's not a big deal was just wondering if anyone else Experiences this?

I've had it happen a handful of times. I haven't noticed any issues with battery life so I'm not worried about it.

I actually had a similar issue when I was flashing another rom at about 30%. When the rom came up it had full battery. So right now I am trying to use hipkat's guide to calibrate my battery.

i just finished the calibration on my phone and so far so good.

It happens to me often. However, you will probably notice the battery life sink like a BRICK out of a plane, but it will stabilize somewhere around the correct battery reading.

Battery won't show charge past 70%. Please HELP!

Hi Guys,
I have spent days researching this, and have read dozens of forum posts, but nothing has worked. Here's the problem- I bought a used GNEX off of Craigslist. The phone looks great and seems to work well. But, it won't show a charge beyond about 70%.
I thought the battery might be the issue, so i bought an a new OEM extended battery, but the new battery didn't make any difference. It still won't show a charge above 70% no matter how long I leave it on the charger (with the phone turned on or off). I have done probably 20 discharge/recharge cycles, but nothing changes.
Next, I bought an external charger. When I fully charge the battery in the external charger and pop it in the phone, it still shows around 70%. So, it is definitely an issue with the phone (not the batteries).
I've also tried four different ROMs, as well as all the black-magic "battery calibration" tricks found in the forums, but nothing helps.
I am totally stumped! Is there anyway I can fix this?
Thanks!
Slim

Please HELP! More info.
Hi guys,
Just an update. Yesterday I tried three different kernels, just in case that might make a difference. No luck. The kernels didn't make a difference.
Any advice on how I can make this phone handle battery levels correctly? It's been on the charger all night and only shows 66% charge.

Hey, Reza. How long has your GNEX been having this problem?

You might try returning to stock to see if eliminating custom ROMs helps.

Same issue here, i tried with another battery that showed 95% in other Gnex and in my gnex showed 60%.....

Definitely a hardware issue.

try an app named "BatteryCalibration" by marosige. When opened it shows the in circuit battery voltage. 3600-3700mV is to be expected from a well charged and in good shape battery. We seam to be having the same issues with mine having progressed to showing 0%. I have a recent thread here as well. I have read that the recovery battery stat wipe is just for the application level, but I think there must be a file or setting somewhere that maps mV to %'s and that this is what needs wiped/reset.

Anyone overhere still having issues?
I updated my thread on a similar if not the same problem, and am looking for some volunteers to help gather a little data. I would like for one or more persons to install SL4A and python, run a script and report findings. If you are willing please post a reply in my thread.
Thank you

[Q] Battery problems

Hi
'Noob' here, be gentle, please.
My original Desire is 2.5 years old. So is the battery that started playing up.
It didn't last long and the phone kept suddenly switching off at about 50%. I guess it's a pretty common problem: Htc Desire Shuts down at 40-50% battery
So, I've bought a new one, "aoonen".
The new problem is that it stacks at 15% when charging.
The LED light turns green and it shows in the Status: Battery status - Full, Battery level - 15%.
Sometimes after plugging out an back in it starts charging and shows 16-17% for some time, but soon it stops and shows 15% again.
If the phone is switched off, the LED turns to amber and remains amber, but the battery seems not to be charging as the phone remains cool and it's the same 15% when switched back on in few hours.
It's original HTC charger and cable, but I did try other cables and PC USB ports to no avail.
Factory reset did not help.
Neither did booting to recovery with wiping all caches and battery statistics.
If I replace the new battery with the old one it shows 100%.
Android 2.3.7 installed by my son (I am no expert in this) in Nov 2012.
Kernel 2.6.37.6-cyanogenmod-g2a32ab1 [email protected] #31. I still have cm-7.2.0.1-bravo.zip on the SD card and used it for the recovery.
If it's of any importance, before buying the new battery I tried using some apps (uninstalled now) that didn't help: Battery Calibration and Easy Battery Calibration.
I like my Desire, I fits all my needs and I am very reluctant to replace it.
Will be grateful for any ideas and advices.

you deserve credit for researching your problem thoroughly .
to be honest, just sounds like a fake/counterfeit battery. it doesn't look like a reputable brand to me.
you've tried calibrating the original battery and still get early shutdowns?
i take it you still need a new one, personally i would recommend official battery if you can find it, you get what you pay for.

I have wrote about same issue in this forum
You have src shots also in my thread.

I have order new bat but I am still waiting for it.
Did you try to wipe battery stats through cwm? Battery calibration should do this but you can try manual also through cwm?
If nothing helps try new battery. Maybe new one is fake.

It was mentioned somewhere as a good brand. And what's the point in faking/counterfeiting some unreputable brand? This was exactly my thought that a 'genuine' battery is far more likely to be fake.

TBH, I have no idea how to calibrate it. I just ran the above apps (one, later another) and they said that it was calibrated, but nothing changed.

"if you can find it" - absolutely. Any recomendations?
Also, my battery is BB99100, but often I see BA S410 for Desire that looks similarly. What's the difference?

no, i've never replaced my original battery after nearly 3 years now probably should, so can't give any recommendations as to where to buy one.
it's a minefield, but be thankful that it's relatively easy to buy a replacement, unlike some new high end phones.
calibration should only be done with proper apps, this is the only one i know of that works, you have to find and follow the instructions carefully, though i've never done it myself. my battery still dies anywhere in between 15% and to 6%, which i can live with and just gotten used to. however if yours is dying at 40-50% it's likely that it's aged beyond its working life.
cwm is short for clockworkmod, he is suggesting you wipe battery stats there, but this myth has been debunked for a while that it does not calibrate the battery in any way.

me too, i dont know

Wiping bat stats - you will get fresh and accurate information about new battery usage. Thats all.

Some user says there: "You must read the tutorial on XDA if you want this to work. Follow it step by step."
Anybody knows where it is at XDA?
The censored link was to "Battery Calibrator" app by Jon Richards

Real calibration is done by:
- wait until the battery is completely empty and the phone shuts down
- insert a charger immediately but leave the phone OFF
- wait until the phone is fully charged
This worked perfectly for me!

Why 'Android System' singly drains my battery so extremely fast?

Hi guys
I have HTC One M8. Android System drains my battery in an unbelievable way. I decide to know the reason. So, I did a reset factory and charged it 100% and then I powered it on and only after 6 min while the screen all of the time was off, the battery got 98%. In the following, I turned off the screen again and incredibly after 21 min without any usage the battery got 94%.
I really don't use the phone and the battery drains such this. Just guess what happen if I turn on screen and use it?!!! I really confused. I took 2 shot. Pls check them out. Android System Singly uses up to 90% of the whole usage.
(When I charge my father's G3 the battery is 100% after 5 min using wifi! Still no 99%!)

is that happens after you flashed a rom and let it settled ?
you should measure the battery life after one day or more from flashing to make sure it's the right measurement after the cash cycle is done

No. I'm on stock clean ROM
All begins to happen from last week.
I felt the battery drains faster than ever.
It was being more and more.
Yesterday, I do a reset factory to get rid of the problem.
But as I explained already I have it yet.
It seems I face with a faulty battery, doesn't it?
Is there any other related reason?
I forgot to add that the phone become very hot. Even in a very essential/primitive/normal usage. In an unprecedentedly way ...

Currently, I'm on a custom ROM; I'm just trying another.
I can return to stock and take some shot, if you think it helps.
Next plan is installing a CyanogenMod ROM.
If It occurred again I buy a new battery instantly.

first you post screenshots from a custom rom then when i ask about the cache cycle you said you were completely stock then you said you are on custom rom and tried to recalibrate the battery with an app (witch i believe it do nothing ) and probably you didn't read the threads i linked and didn't gave us any useful info to understand the situation so we can help
the last thing before buying a new battery run the appropriate RUU for your device and see how it's going

I have some good reasons why I said you I'm on stock when you ask me for the first time. Yeah! I remember!
I tested both before posting on XDA and the result was same. Mr.Ismael I certainly sure if I said I'm on CUSTOM you picked on CUSTOM ROMs and blamed it.
For this reason, I said I'm on stock in order to skip that MISTAKE IDEA that the custom ROM causes the problem
Just because getting rid of this mistake. No other reason.
