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

[HOW TO] Calibrate Desire Battery

Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.
Mod Edit: There have been a few reports of damaged batteries by people on this thread. There is a chance that this MAY damage your battery. Please bear this in mind if you choose to follow the instructions above.

supportyou and the app!

Thanks for that. At what point do you wipe battery stats? After the process is complete?

Also wondering about this

You should wipe battery stats after its fully green (when powered off) then boot the phone back up.
You only need to do this once
I.e.
Charge till full when powered on
power off
charge till full again
boot into recovery wipe stats
boot and continue to use as normal

It works!!!
That's fantastic!
I read this topic this morning and tried immediately. Since this morning i only lost 4% until now. That's great news!
Thx a lot, man!

takes a long time to charge my Desire, but then i'll test this one!
Hope this will make battery life better. I have the same problem as described in first post (drops immediatly from 99% down to 93% )

Can someone suggest me how should I go about doing this if I use multiple batteries?
I'd imagine the phone can only be calibrated to 1 battery. But if I were to use another battery, would I screw up the calibration to the original batteries?
Right now as it is with moderate usage I need 3 batteries to last me through the day. :S

3 batteries?!
What rom are you using and how exactly are you using your phone?
I have just one battery and it lasts about 2 days with moderate use.

I am using this ROM: (sorry can't post link)
[ROM] Rooted Official HTC Android 2.2 (FroYo) ROM [Market issue fixed]
With my typical usage, I unplugged the phone in the morning from the charger, by the time I knock off from work, I would have left about may be 20%. With stock ROM and a single battery, there is no way that I could last 2 days with one single charge. My main use is web browsing, RSS, Facebook and IM. My estimation of my solid screen time is about 2-3 hours.
So I bought more battery just in case, and played with custom ROMs. I ended up using up a whole battery in 4 hours or so. Definitely something is wrong here. My gut feel is that both the ROM and batteries are suspects. Being a newbie I really need enlightenment.

Is it really needed to wipe the stats? I think I've accidently done this once already... cause the battery life is much better.

since this procedure, my battery stays at 100% since nearly 2 and a half hours now and i did 2 text messeges in between and recently checked the bat about 4 times
this couldnt be possible..
i mean the battery is almost doubled in comparison to how long it lasts before
is this possible??

yes it is possible

but how?
i mean in this time the battery would have been dropped to arround 97

i mean these are stats how are they increasing battery life? the batterylife is given from the cell itself?

Wrong Battery Status

Hi
my wildfire can't charge more than 5% i know it is not battery fault because i have used two different batteries.
i wiped my battery 5 times i wiped everything a changed my Rom Changed my kernel.i am using CM7.
i read this topic http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10
but it is for Motorolla and when i pull out battery my phone turns off immediately.
i used http://forum.xda-developers.com/showthread.php?t=1597846 but it didn't work for me.
i tried to restore my phone to official rom with RUU but i can't because it says that your battery must be more than 30% so i don't know how to do that thank you everyone please guide me?

Try installing battery caliberation from play storeand follow the instructions given in the app. It might help.

i think it's software problem not hardware because i changed the battery with another battery which was used in another phone and it was full but in my phone the battery status was 11% when i put it again to another willy it was 95%.

It doesn't charge after 5% or it doesn't show more than 5% battery? Huge difference between the 2

Exactly. And if it is like that, then use the calibration tool while your phone it on charge.
Again asking for clarifying....is you phone not charging beyond some % or is your phone not showing the charge beyond some %
?

I am having a similar problem but mine doesn't charge beyond 75-80% depending upon when I have plugged it for charging.
If I start charging at say 50%+ it charges beyond 80% but does not fully charge, and if I start at say <40% it does not go beyond 74%.
Now at this level if I restart my willy the battery shows 90+% and I can charge it to 100%.
I have tried everything wiping the battery stats, using the calibration tool nothing's really working. I doubt when I used a Samsung charger for charging that's where the electrical circuit might have got damaged or may be when when I dropped it from 4-5ft.
Since I have already rooted it I don't think HTC service center will help me here with motherboard or electrical changes.
If you guys know any method lease let me know and btw it's >1.5 yr old battery.
Thanks

can you explain more?shall i charge it then remove battery and then start charging again and again?i could reach to 42% woooow but not 100%.
can anyone change the codes of battery by making a flashable patch for just showing 100% of battery(not real status) i need this for calibrating my battery.but batterystats.bin wasn't useful

This issue may have been solved, but I'll post anyway.
You can calibrate your battery when it's lower than 100% using the app mentioned above. There is an option within the app to calibrate it regardless of battery percentage, just click that option then calibrate.
Hope it helps,

Battery drainage on HOX

My battery on the One X I think is bad, when I check facebook or Twitter on WiFi, it drains 1% every minute and it annoys me. Playing simple games also drains 1% every minute...really annoying. Is there a problem please help?

It happens to me as well, but only if I turn on WiFi and let the phone use it´s online services.
Hoping that the Jelly Bean update with Sense 4+ brings some kind of optimization.
I have my HOX configured pretty much like my SGS3 and my S3 lasts 20, 30% longer and about 7ºC colder.

Same here, kinda want to change my phone again if HTC doesnt fix this problem.

do a battery calibration, app like this works https://play.google.com/store/apps/details?id=com.nema.batterycalibration&feature=search_result
before the app 1 day usage = 60% of power left
after = 85% left
HTC made too much of the safty triggers for the battery if u use it lightly every day its minimizing side effects by making new one (less charge)

How long have you had your One X, OP? It takes several full charge cycles for the battery to calibrate, it's one thing about One X that's weird. I remember being completely disheartened with battery life when I first got mine - and it was horrible, pretty much like you've described it, 1% every minute or so - but only kept it because my mobile operator wouldn't replace it before making sure there is a hardware malfunction, which could have taken weeks, and I was impatient. Then I learned from xda that this slow calibration phenomenon is a thing with this phone.

I hope you're right svucinic811 I'm really getting worried here

I am wondering what a good rate of discharge is cos if i leave it on standby overnight it went from 99% to 79% in about 8.5 hours. personally i think it should have been 99% to 89% in 8.5hrs but anyways...

It should only discharge at most a few percent. Check your wakelocks with BetterBatteryStats.

Will this work even without rooting my phone? I'm running on Stock Sense 4.1, but this seems like it would help a lot.
As well, if you (for a couple days) go without charging your phone in the middle of the day and let it run down until you charge it again I think you will see some results in the battery life. My battery would die everyday before school ended for me (Wake up at 7:00 AM, Phone dead by 5:00 PM). Unless it was just a placebo affect for me, its worth a try.

Does anyone else has this problem where, yes the battery drains fast, but takes forever to get charged to 100% ? FYI, I'm using the real charger, not via PC~USB

how do i calibrate betterbatterystats?

What's forever? 3 hours is about normal, unless you're heavily using it.

You don't have to calibrate Better Battery Stats. Just charge it up to full, then wait for it to happen again. Open it up, choose Since unplugged (obviously you should not have plugged it in at any point of time since the full charge), then take a screen shot of Kernel Wakelock, Partial Wakelocks and Process.
@Rohin, USB Cable quality plays a big part as well. A cheap rubbish USB cable even connected to the wall socket charger can only charge at 300+mAh, while a good one can charge up to about 750+mAh. About 85%-90%, charging usually slows down to about 200-300mAh, then slows down even more as it approaches 100%.

So give it about a few hours on standby and then run BetterBatteryStats, then select partial wake locks from the drop down box and it should present you with a list of the wake locks, easy enough?

[Q] Is this battery dead? (Bad battery life, battery percentage jumping)

Hey there guys, fellow developers, I have a problem with my battery. To be honest I can't really tell if it is slowly dying or whatever.
I bought a used HOX and I am having weird battery behaviour. As you can see, I can get these stats over a day. (see attachment)
The battery percentage often jumps over time. When I'm multitasking/playing a game/surfing net, the battery often stay for example on 62% and after 5-10 minutes it immediately jumps down for example to 50% without showing proper battery percentage.
And vice versa... When I reboot phone with 30% it will reboot and then I'm noticing battery percentage jump but to the other side. (for example to 35%)
Today it jumped from 4% to 61% when rebooting. Lol?
By the way, charging is too slow and when I'm using the mobile at the same time it doesn't even charge up.
Sorry if this is solved somewhere else on forum, but I could not find that.
Thanks in advance guys. :fingers-crossed:

I am also expressing the same battery problem.... Does replacing the battery solves the problem because this will be again 1800mAH battery???

I kinda have the same problem. With "kinda", I mean the battery meter will sometimes drop down in 4% or 5% increments (ex. from 56% to 51% immediately).
Thinking of changing the battery too. If you did change yours, be sure to let us know if everything is back to normal.

Okay, hope you fix your problem. Be sure to let us know.
As for the slow charging, if you're using a USB cable, you could try a custom kernel and enable "fast charge". The phone will charge with the same speed and voltage as an AC adapter. (It will disable access to your USB storage though until you untick "fast charge").

Even with fast charge I'm facing same problem like all they do ...
