Develop Bugs

Anyone else having issues charging the battery?

As you can see from my capture, while on the ac charging, the percentage suddenly drops for no reason...its not like it discharges and charges back up, it drops and stays there...is this a problem with my device?
Was flashed to stock root froyo recently.

Hi,
I have same issue...
It's a rooted Froyo Stock Rom. It drops from 100% to 90% and continues charging.

It is a known issue, acutally many claim it is not a problem. If you leave your desire on ac charge (for ex: overnight) when it reached %100 and stays there for a certain period of time it starts using phones battery. Then it chrages again until it reached to 100% and the same cycle starts. People say it is to increase batterys life because contiues charging decreases battery life.
I believe it started with 1.21 update, when I was on 1.15 this thing never happened. However, since I installed 1.21 and froyo same cycle happens to my device as well.

Thanks for explanation and link!

Thanks for the explanations. Helps a lot.

Thanks for the reply, the only problem is in my case, it doesn't seem to charge back up to 100% after the drop. Also mine doesn't seem to discharge; it is a sudden drop from full to 90% while having the fully charged LED green. Do you think its a problem with my battery?

I hope its possible for the developers here ( or maybe at HTC ? hehe ..) to make a fix for this , as some people saying a software update started the whole thing.
and if its a "feature" , people should have the choice wether to have it or not.
I'd rather change my battery after 6 months or something like that then have 92-95% in the morning.

Same here. Not sure if HTC acknowledges this...but it doesn't seem to affect that many desire users apparently so it could be a bug.

I also have a strange problem with my HTC devices (Desire and HTC HD2).Both of them are running froyo.It seems that when leave them charging overnight,the next morning when i wake up i went to check out my phones and they happen to be at 96% charged only.I was pretty scared that my battery's starting to fail me

Battery life-desire 88% display!

Hey guys how is everyone? Just a quick one...
In the past 12 months I've had my desire I'm shocked at how short my fone battery lasts. I can barely get 8 hours off the phone without a recharge. The phone sometimes switches off as soon as it gets to 15%. I've tried to calibrate the battery, wiping battery stats but all to no avail. Just this morning I've had the phone on for 1hour 10mins. From a full overnight charge its already at 64%. Battery use always shows the display to be using atleast 70%! I'm on the old amoled desires. Anything I can do peeps? Cheers

What's the total time of battery?

NB. Currently using android oxygen 2.3.3. Noticed no difference in any of the default htc roms I've used.

Been on 1hr 20mins and its shed 40%. I can try and take a screenshot for you guys

That sounds about normal to me, it sucks, get used to it or use your phone less. sorry.

Also forgot to mention screen brightness generally between 30-50%. Cheers folks

You probably messed up your battery with all that "calibrating". Unless your standby usage is significantly more than 10mA there isn't much you can do.

I had the same problem with oxygen. My fix was to unpartition my SD card. So no ap2sd. I use the hboot for different. I easily get 24 hrs with heavy data and video use.
May need a fresh install.

20% Battery Shutdowns

Hi all.
As a desire user you're sure to understand what problem I'm talking about. I've tried calibrations and testing but still my phone turns off at 18-20% battery.
Im running cm7r2 hboot with Runnymede&Bliss mix Wmjan Sense 3.5 Rom.
Would anyone please help with some clear cut instructions?
With kind regards.

One thing: when discharging phone from 10% ... Did you let the phone turn off at 1% and then recharged it to 100% on rebooting or the moment it said 1% you plugged in?

Method that is described here is the only working solution to calibrate battery. Deleting batterystats.bin does nothing (because they are deleted every time you plug off your charger when at full or near that)

I've said it before and Ill say it again. 20% shutdown is just a problem with battery calibration, its not a problem with capacity. Even though you phone shuts down at 20% the capacity is unchanged. The easiest solution to the problem is just to remember that 20% = 0% for you and live with it. Going through a lengthy fix is not worth it imo.

Fix is not lengthy. It can be done in one charge cycle plus some elementary math if you know how to read.

Cant remember where I read the original article (think it may have even been on XDA front page) but her is another one I found after 30 seconds of using the google machine, which has some very pretty graphs that may enlighten you.
http://78michel.unblog.fr/htc-desire-battery-shutdown-analysis/
And the conclusion is *drum roll please*
"As the discharge current is constant and almost identical in all tests, it is clear that the old batteries ( Part number xx-01M and xx-05M) have both lost about 15% of their initial capacity as they stop about 15% earlier.
Why the HTC Desire ( and may be some other smartphone ?) is not able to take into account such a capacity loss?"
You are very welcome.

I installed the kernel from the battery fix i think it was version 5. Run the battery calib app. Followed the instruction on the forum. And now my battery shutsdown on 0%. I'm using Seb's Runnymede AIO v6.1 Beta

If I might observe that you're very cocky for someone who failed in his statement and then linked to the article that proves that fail.
Indeed, article is true, up to the point we all know now, thanks to theGanymedes research, why battery percentage and capacity get misaligned, with wonderful guide how to fix it easily, au contrair to what you said.
You wrote this:

So I see two possible things at work:
a) lapsus linguae due to lack of punctuation, so even if you thought that the as it's age grows battery looses it's capacity (which is kinda self explanatory), it was not what you expressed.
b) you stated that as battery grows older, it's capacity remains unchanged, and if you can find a proof of that, you should be hired by some of battery manufacturers.
Either way, your rhetoric goes with situations where you are 100% right and can not get disproved, which you have been here. I strongly suggest not to pursue that path any longer here.

Well, making the long story short I decided not to calibrate the battery. It's a long process and terminates if the phone is charged while it is off.
I flashed a different rom and kernel. Getting 20-22hr battery (100%-20%)
My 80% battery provides me almost a full long day. So I'm happy with this. Btw thanks for the help folks.

Only charging to ~65%

Hi,
i usually charge my One X over night with the original HTC charger.
I use a custom ROM (Charmeleon) but experienced this also on stock a couple of weeks ago.
Sometimes i wake up, unplug the phone and it's kind of hot and only charged to about 65% although it was plugged about 8 hours.
This night it happened the second time in a row.
Has anyone the same issue?
Thanks
Regards
Daniel

You need to reset the battery stats, though I'm not sure how to do it on a HOX; I'm still unrooted, locked.
Usually it's through recovery. Basically since you flashed the rom at (possibly) not full battery it thinks the battery is full at 65% on the new rom.
Sent from my HTC One X using xda premium

No, that's not the problem because i use this ROM for a week now and it charged without a problem the other days. And as i mentioned, i also got this on stock one time...

Since you're rooted and unlocked it wouldn't hurt to wipe the stats again. Charge it full, turn it off and charge it for 10 minutes, turn it on in recovery and wipe stats. Then let it die completely and charge it full. Should be fine.
Sent from my HTC One X using xda premium

I highly doubt it just isn't charging.. Maybe restart it before you sleep? If you possibly have a ton of background stuff running? I can imagine it wouldn't charge due to that though. It could also be a deeper problem that might need a full wipe and re flash...

Hmm the last two charges were fine. Very suspicious... :-/

There may have been a connection problem with the cables, happened to my brother when he didn't use the factory charger.

I use the original htc Desire hd charger with a Kindle USB cable.
But if thats really the Problem, why does it work Most of the time?

BTW i wiped battery stats before.
I think i will wait for the next Charmeleon Version to come and wipe completely then.

Yeah, do that.. But a third party usb extender caused his problem. Weird, I thought. It wouldn't even charge enough to get past a black screen, it scared me I thought it was bricked. A little adjustment of the connection fixed it but needless to say we don't use that cable anymore.
Sent from my HTC One XL using xda premium.

Now i got the same issue with the original cable. I charged it at work after it charged only to ~67% over night and suddenly the notification led started flashing orange and green and the phone got very hot.

I'd definitely return it to the retailer its clearly hardware..

Try battery calibration app from the play store, i used this to sort out a similar problem on my old desire.

This app deletes the same battery stats which have been mentioned above, its just an easy way to do it.
Sent from my HTC One XL using xda premium.

Has anything changed on Android 4 about the battery stats? I cleared them the first time after i installed a custom rom.
Before my One X has charged about 70 times without any problems (just 1 time i got this error). After i installed the custom rom and cleared battery stats (via "Battery Calibration" from play store) i got this issue more and more.

I am all for the easy way.

I have the same problem with my HOX. From what I noticed this happens only if the device is really hot. As soon the temperature goes down it starts charging again. From what i've read on google, it has some settings from stopping it from charging on high temperature because the Li-Po battery can explode much more easier then the Li-On one.

I installed ARHD 7.1.0 this morning had 90% battery after installing, thought id top it up to full when i checked 15mins later it was still at 90%. Rebooted into recovery deleted battery stats and started charging all good.

You have a very badly made app working in background, eating the battery, heating up the cpu, this could be related to modified unstable ROM. Forget about battery calibration, android does that automatically for 1 reason only - to show you the most appropriate percentage when you use the battery itself, it has nothing to do with your problem.

I'm one step closer - i maybe found the cause, but not the solution.
I installed Current Widget yesterday and enabled logging. At midnight i connected my One X to the factory charger and went to bed.
At 7:00 the phone was really hot, Battery indicator showed 58°C and the battery was at about 70%.
I checked the Current Widget immedeately and found out that the phone charges to 100%!!
0:00 5%, Plugged in
2:54 100%, Fully charged
3:44 100% Charging state, kept until now
4:40 69%, Until now constantly losing charging state
4:41 70%, Seems to charge again
4:56 69%, Charging seems not to work
5:20 71%, Charging again a little
7:00 71%, Just kept the state and changing between 69 and 71%
7:01 71%, Plugged out
The "jobs" that run over night are:
02:00 Sms Backup and Restore
03:00 Titanium Backup - Backup all User Apps and Data
04:00 Whatsapp Autobackup
How can i find out what is the problem / Causes the drain?
The phone is in airplane mode the whole night.

Wipe ur battery stats, drain ur battery then charge uninterrupted till its full, drain and charge again so that max and min battery levels are well calibrated. A battery app like battery doctor will help keep ur battery in giid shape.
Sent from my HTC One X using xda premium

Perhaps is there another reason. When you install a new rom, you must wait several cycles of charge/discharge to have a good battery life.
So, interrupt his charging cycle isn't the best way for battery life. And yes, you must wipe your battery stats to.

Now my battery died, when i plug charger, sometimes led blink 2 times with red light, and it's over. I will replace it. I pray for battery issue, not motherboard. What do you think about this problem?

I had the same issue under Sense 5 roms.
With the phone on and charging I never reached more than 60% of battery even using battery optimizer.
The solution for me has been back to a 4.2 AOSP Rom (ICJ in my case) and a couple of cycles again my battery works as usual.
I tried again with a S5 rom and the issues are back, so I have to use no Sense 5 roms if I want my battery right.
You can also try to charge in Recovery, that worked for me, to wake the bootloader.
Hope this would be useful for you.
Cheers.
PD. Sorry for my english

Have you tried a stock sense 5.0 rom?
PS. Maby we have the same HOX cause of same problems

I´ve tried ARHD & MaximusHD, both with Stock kernel and Alex-V S.E. 2.1
Always with the same result.

This week i found something that seemed to be a issue like the one reported here. My phone goes without battery before i got to sleep. I got my phone to charge on the Wall charger (HTC OEM). When i woke up i figured out that my battery only charged up to 15% (Froze at 15%)
It is the second time this has happened since the Sense 5 update (OTA Update).
Never happened before.
