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

Boostmobile evo battery drain!! Help!!

Hello all, I hope all is well! I have a huge problem... I've been running my evo on the boost network for the last two months and have been getting no more than 4 hours of battery use from every rom I use. I even tried the old destroyer rom and a number of different kernals. Im in need of help as soon as possible!!

How about a little more info. What battery are you using? How old is it? Have u checked to see what is running? Did this start as soon as you switched networks?

Im using the stock battery and its only about 3 months old... It was a claim from asurion. It started happening soon as I switched networks. While on sprint I could easily get a day 1/2 usage.

It could have something to do with your radios, or just be a random coincidence with something else that's causing the drain. I'm not familiar with flashing to Boost at all, so I don't know if you have a different set of radios, PRI/NV, etc. You could try flashing a different radio, newer or older.

Just updated to the latest radios and battery still sucks!

I have Boost too.
The battery drains quicker with low or no signal.

download Spare Parts and check Partial Wake Usage, this will tell you if an app or apps are causing this.

Well I GUESS THIS IS DEAD...

Be sure to calibrate your battery whenever you flash a new ROM to optimize battery life. I prefer to calibrate using this method:
1) While your phone is powered on, charge the battery until the LED turns green.
2) Unplug the phone from the charger and wait until the LED turns off.
3) Now power off your phone.
4) When the phone is off, plug the charger into the phone and charge it until the LED turns green.
5) With the phone still off, unplug the charger and wait until the LED turns off.
6) Now power on the phone.
7) Wait until the phone is booted completely and then power off the phone again.
8) When the phone is off again plug the charger into your phone and charge it until the LED turns green.
9) Now boot your phone into recovery mode and navigate to the "Advanced" option using the volume up and down keys and then choose the option "Wipe Battery Stats."
10) Now reboot your phone and use it normally. You should notice improved battery life.

There is also an app called battery calibrator, its free on the market. I use it with great results!

Wiping battery stats is actually been found to be ineffective/cause more harm than good the best way to actually "calibrate" the battery is to backup your rom flash to aosp or froyo with an sbc kernel let your phone drain til it powers off boot it back up and let it shut off again usually only takes a few mins sometimes it wont power on again, plug in charger wait til red led stops blinking turn the phone on and charge it to 100 uninterupted and leave it plugged in for 15-30 mins at 100% then nandroid back to your back up do this once a month or find an aosp setup u like and stick with it, the myth of sbc damaging li ion batteries is just that a myth newer phones have trickle charging kernels stock now such as the rezound et4g and a few others that i dont remember off the top of my head

Well, everyone has their own opinions. For me, I prefer the method I posted over the app for battery calibration, because I get better results. Also, I've never heard of any negative side-effects from wiping battery stats, but feel free to do what you wish.

no signal horribal battery

Monday and Tuesday I stayed in New Orleans Louisiana. I typically had 5 bars as far as signal goes.. While there I didn't have to charge the phone at all for 2 days with heavy usage might I add. The minute I made it back to my small town, the battery started to drain incredibly fast! So I've come to the conclusion that it is the poor service that drains the battery. With that being said, I would like to thank you all for your input!

[Q] HTC One X battery life issues, first charge problem or.....?

Hey guys, I just got my HTC One X a few days ago and this is my third day running on this phone.
I wonder if giving it a first charge for 8 hours was needed to condition the battery and giving it as much battery life as possible.. Because when I first received the set, the set was without juice. So I charged it up till about 15% and I received a notification about an FOTA update and I went ahead with it.
After the phone reached slightly over 35%, I let the phone install the FOTA(while still at it's first charge) and it hanged halfway.
I didn't know what was happening so I tried rebooting the device(as removing the battery wasn't possible with the One X). After several tries of holding down the power buttons, I removed the microUSB cable attached to my phone and the phone went blank and it restarted by itself.. Take note that the battery was only at ~30% at that point of time..
And one thing I noticed when the phone didn't respond during the FOTA update was that the AC plug was not as hot as it was used to when charging.. Yeap, so does anyone know if I have actually 'damaged' the battery or maybe it's just the handset that's power hungry? Thanks!
PS, Thank you for taking your time to read this long wall of text and taking your time to reply to my query!

I'm not too sure what the problem is now. Is it about the power draw, or did you brick your phone and wondering if it was caused by a damage battery on your side?

Well, I'm just wondering if me not giving a proper 'first charge' has anything to do with it's poor battery life or it's just natural for the device to be this power hungry, haha.

How much screen on time ate you getting?

You shouldn't charge while flashing the OTA.
I don't think you did any harm.

I haven't been able to get any numbers yet because these few days I've been running the phone mostly plugged into the wall socket. Yeah.

I only had a two hour battery life after the first complete discharge and 8 hour recharge.

Assuming your FOTA Succeed,
Try...
1. disable fast-boot (Settings > Power > Untick fastboot)
2. Power Off
3. Charge (until green / 100%)
4. Power On
5. enable back fast-boot
6. Hopefully you got real battery-stats already

I've noticed some improvement of the battery life of my phone after flashing it with a custom rom.
With a giant screen, a powerful processor, and an elegant packaging, pour battery life is kind of expected, for me I've put chargers almost in every corner of my home, at work, and in my car.

I normally get about 3.5 hours ++ screen time on a full charge, auto brightness.

I am getting 5 hours of on screen time on my stock Rom. Is that possible to get more screen time like 9 hours on custom Rom ?

I didnt charge it when I first got it either. I booted it instantly and used it untill the battery was completety drained and the phone shut down untill I recharged it completely and my battery life is horrible. The worst of any HTC one x so I wonder if I might have damaged the phone aswel??

Charging it when you first get it does nothing. If you have such bad battery life it is probably a faulty phone.

When I first got mine I ran it till it died then did a full charge so that shouldn't matter at all.

My battery was ok on 1.26 then updated to 1.28 and it went beyond awful but after about a week of use on 1.28 my battery has improved a lot... Bought an external charger while was waiting on next update but before I received the charger battery went boss !! So my guess is give it a few days and don't be inpatient with it as it will come around

I'm having issues with my battery life. I'm also new to the Android platform -- well sort of, I've used CM9 on my HP Touchpad for a while now, but this is my first Android handset. I've had the phone for almost a week now, and I've noticed that I barely get around 9 hours of moderate use per charge. On average my on screen time is about 3.5 to 4 hours. That is terrible. My iPhone 4 is lasting twice as long as my HOX and I've had that thing for about 2 years now. Any tips on improving battery life?

[Q] Can a battery go bad this fast?

Hi all,
My SGS3 suddenly since last night has not been able to recharge, battery critically low. I have tried a few chargers, and rebooted several times.
Can a battery go bad this fast, because looks like it was charging and running fine the day before.
Thanks

Have you tried loading a stock ROM on there just to be sure it's not software causing harm to your battery? Not sure if your provider will warranty your battery if it is indeed your battery.
Good luck!

Hi, thanks for your response
It actually is stock rom, sorry forgot to mention it. It is rooted, but I never replaced the rom, just put in CWM recovery. I just moved from rogers to virgin mobile last night, just changed sim card. But the multiple reboots killed a maybe already weak battery?
Thanks

You should download and install better battery stats, it may help you find out if its being kept awake and draining quickly that way

Thanks for your response, necrowakker.
I guess that I forgot to mention as well that the phone was shut off during a recharge, and upon powering up, it still it complaining to plug it into a wall charger.
Like it was never plugged in.

When you rooted your phone was the kernel changed? .. I've had experience with some custom kernels not reading the battery correctly when off, and only after switching it on it still States its low til a little while later it actually looks like its charging .. ( like the battery level goes up over time) while being off the charger.
If thats not the case, try charging your phone again, but while its on after you know its definitely discharged and not just a ROM memory issue. If you turn it off to keep from getting calls during the night switch on airplane mode to keep that from happening. And check if your battery does on fact charge correctly. ...
After 3 full charges and discharges your battery still gives you bother. Then you can either look into what process it was when you rooted,
if it did change anything more than just giving you more access, or see about a hardware replacement, if it is under warranty, and you can take the flash counter back down to zero (if it counted up) and unroot it.
Also using unsupported chargers over the recommended charge rate for your phone, could have done it damage but that's a long shot with today's safety measures on phones.
Edit:
Don't forget to install better battery stats too, just for checking and reporting. Stable ROMs should be able to handle over 300 hours up time before needing a reboot. So using airplane mode should not bother your phone too much

Thanks for all that info.
The phone has been rooted for at least 6 months now. It has been running very good until this morning. No kernel was changed for the rooting. I just wanted titanium backup to work.
I am still presuming that maybe the battery was weak, and when I was changing out the sim card of the service providers, I did reboot about 15 - 20 times to try to get all the services running, maybe that was enough to kill a battery.
Heeter

I've don't some silly **** with powering and charging and pulling batteries for every reason, I can't see Samsung giving you a bad battery if its worked fine for 6 months, you'd probably know within the first 6 weeks if it was faulty. ...
It may easily be a software memory issue with the battery that's confused it. If you are using cwm as a recovery it may have the erase battery stats option on it, if so give it go,
charge your battery to 100, allow it to drop to zero, or til it shuts down, plug in, power it on allow to boot, and leave to charge to 100,
once that full discharge and recharge is done, your battery has its full stats. If it gives you hassle after this point, think about buying a registered Samsung replacement for your phone.

Battery issues since "charging current is not enough for device power consumption"

Battery issues since "charging current is not enough for device power consumption"
hello,
Few months ago I received this error message wile i was sleeping and carging my phone over night:
"charging current is not enough for device power consumption"
Since then my phone is like stuck at 30% battery (example), when i dont use it, soon as i play/do something (Facebook, games etc.) it jumps from 30% to 20%. Basically the battery percentage doesn't show it's real state during standby (thats my theory I mean)
Also, when i press and hold the power button so that te tree softkeys blink (i dont remember the term for that procedure) it reboots normally but when its finished with rebooting, it shows me a completely different battery percentage (example: I shut it down wit 60% battery left, it reboots and shows me 72% or whatever, just an example)
I am rooted, running ARD 33.1 / stock kernel.

/bump
Can anyone tell me if it's hardware-related? If that's the case, I'm ordering a new battery.

Perhaps its just the readings that are wrong. Maybe try this......
Download something like 'Calibrate battery (root)' from the play store
let the battery totally run out
charge it to maximum (while its off)
then as soon as you turn it back on, run the calibrator. IF its just a problem with the way the phone detects how full the battery is, then it should be sorted.
If not....well at least that's one possibility knocked away
