Battery issue???

I think I might have a problem with my battery, but I'm not sure. I had it on the charger for 12 hours. So the battery should be full. When I took it off the charger, the status bar indicated that it had dropped down a notch. Is this normal? I was expecting the battery indicator to be fully shaded in white.

Ok. So I restarted the phone. Now the battery indicator is showing that it's completely full. Hmmm.

This happened to me too today. I'll try a reboot...

Please remember that your battery needs some time to kick in and settle before you'll get full charges/power and correct indicators. If you just got your phone on Monday, wait about a week, and your phone should last longer and display more accurate approximation of battery life.
If it has been much past a week though, and your battery life is still significantly poor, then it may be your battery, device, or how you have the system configured.

I've commented on this a few times before, the same thing happens to me.
Its obviously a bug with the OS or something as I am now on my second HD7 and it does exactly the same.

let the phone battery drain out then let the phone charge completely with out using it. You will see a huge improvement on your battery life and the phone will charge alot quicker. That will also fix the battery indicator bug.

Ariel is right.
Remember for best optimization of any battery is when u use it 0% to 100% and then let is drain to 0% again.
i have the phone since a week with 5 charges i am not happy YET with the battery. Hope it opens up as ppl are saing.

I forced my battery dry a couple of times between charges using the HTC Flashlight app.
Run the app on maximum beam (you might have to wake it up every now and again) and the battery drains very quickly. I turned on wifi and set some music playing as well for good measure.
Then charge using the supplied charger rather than a PC USB connection. I'm not sure if that's meant to make a difference but mine charges up much faster that way.

Charging your phone through USB to PC always takes longer then using the charger

I'm getting about 15 hours of battery per charge. That's with moderate use (text messages, e-mail web browsing, a couple phone calls). This is MUCH better than when I first got my HD2. The battery would drain about 1% every 3 minutes. It was absurd. I'm pretty content with the battery life thus far. Windows Phone 7 is such a pleasure to use.

friend has an evo and he's trying to sell ot to get an hd7 lmao

I got the HTC Surround and I noticed the same thing. After coming off a full charge (the whole night) I loose what looks like 5% of the charge within the first 5 minutes. Sometimes it's after as much as replying to a text.
Hopefully the battery has to 'settle in', as others have suggested.

Battery life and usage..

I'm having like 13hours to 14hours of battery life..Running stock ota 2.3.3..is it normal for such a battery life?(when my phone is fully charged right after I plugged out the charger,my battery drop to 94% to 96%is it normal too?kindly advice..thanks..

My battery indicator also drops from 100% to 96% a few seconds after i take out the charger. But after 2 days i stille have about 15% battery left.

My battery life increased after upgrading to gingerbread. I can usually go through the day (15 hours) with 3g always on, twitter and fb sync on, with light gaming and surfing of the web, 75% brightness.
My record was 2 days 9 hours with 0% brightness, no 3g, only wifi, no gaming, twitter and fb sync on.
For your percentage problem, you can try draining your battery, then when the phone shuts down, hold the power button to switch it on again. Start up an intensive app like a game to further drain the power. Do this until the phone does not start up (no bootscreen), then plug into the charger and charge overnight. DO NOT turn the phone on during the charge. When you turn on your phone after the overnight charge, it should read 100%
I am not too sure what triggers this, but its likely due to battery memory or something, although this should not be happening for lithium batteries. Maybe its a software fault. Do this every month or so to hit that 100% indicator. It is not advisable to do this all the time as draining the battery completely MAY damage the battery over time. Cheers!

How did you manage to get pass 2days of usage?

Hey,
I'm also having the same issue. Off the charger, BANG! 96% or so, sometimes more. My phone will be at 90% after like 3 texts. Its only had 5 charges mind you, I know there's a "conditioning" time but still, is this normal? I can almost say a text is a percent...my 3gs had more batt life after 1yr... now that's saying something...haha
I can almost watch it drain with the screen on...like 60 secs is a percent or 2...not cool...
Maybe I can do the "Desire Battery Calibration" procedure after a few more full charges...might make a diff...what do you guys think? I may be jumping the gun here...
Thanks in advance.

I remember someone said modern phones are designed not to keep on charging after reaching 100% and resume only after dropping to certain level, maybe 9x%. That could be the reason why I see different percentage left every day I unplug the phone in the morning. But my last Hero always show 100%.

That sounds right, because it drops from 100% to 96% after a few seconds, and its direct from 100 to 96.
But if you put the charger back it taks a couple of minuts to get from 96% to 99% and about 10 minuts to go from 99% to 100%

As far as i have noticed, this was the issue with X100 too after 2.1 update-
Once connected to the wall socket, the phone charges to 100% and starts dropping.
it does not charge again unless you reconnect the charger.
till the time it is connected, it will display as 100% but once you remove it drops to how much ever time has been spent since it reached 100%.
why that happens, i really don't know.
Ideally the phone should continue charging if the level is below 100. anyways....
about the battery backup, i think 13-15 hours is quite good for a phone with this display and capabilities.
with 3g, a little gaming, surfing, chatting etc. this should really do.
in fact, post the 2.3.3 update, the battery life has definitely increased.

So you think that having a 13hrs ++ battery life is good enough?More advice please..thanks..

I am on a VzW Inc2 w/ Froyo so not sure how applicable any of this is for you guys...but anyway....
My battery life is fantastic. I too see the 100% down to whatever after unplugging - I am pretty sure this is like others have said; once it reaches 100% during charging it stops charging and does not start again until you unplug and it re-plug it in. I know in my case charging from dead to 100% only takes like 3 or 4 hours. So if you are plugging your phone in when you go to bed it is probably hitting 100% after 3-4 hours and then the rest of the night it is draining down...
I have found JuiceDefender Ultimate and JuicePlotter to be huge helps to me in decreasing battery drain (JD) and understanding what uses the battery (JP).
Also just going into settings, About Phone, Battery, Battery use - this helps understand what is using it.
*Note: JuiceDefender Ultimate can create more problems than good if you are not willing to take the time to learn/set it up.
Prior to using JD and JP I would generally make it through the day, sometimes have a bit of power left over. After using these I always make it through the day, and sometimes through 2 days.
But let's not kid anyone - what JD does you CAN do manually...but more than likely wont or will forget. So for anyone that doesnt want to use JD, do you leave your WiFi on all the time, or do you switch it on/off? Leaving it on all the time drains battery. When WiFi is available, do you use it? I have found WiFi on this phone to use a lot less battery than 3G.
Probably my favorite function of JD I have it disable 3G and WiFi when the screen is off (for getting emails, updates, etc... you can set a schedule where it turns it back on during intervals or whatever).
Also I like the WiFi Location setting - you can teach it where you use WiFi and it will automatically turn WiFi on/off based on your location.
Anyway - my guess is if you are having low battery life, either you are using the device a lot more than you think (voice calls use a lot of battery), you have things syncing too often, or you are leaving radios/etc... on all the time that do not need to be on.

I tried to take the charger out at the same time the battery was on 100% and the LCD light went green.
Then the battery stayed at 100% for about 11 minuts and then went down to 99%.
After 3 1/2 houres the battery is at 95%!!!!!!!!
Bagground Data is enabled.
3G is active.
I have mail check every 15 minuts.
Screen brightnes at 40%
Weather update every 1 houre.
I don't use Facebook, Twitter, Stcoks and News.
I don't understand the battery in my IncS...

You guys know that these batteries don't have memory right? So when you charge doesn't matter, your phone just thinks there is that percentage of battery, do a full drain once and then it should back on track. Also, these batteries never get charged to 100%, its a safety precaution or something of that sort. They hover around 94-96% which is why the phone drops down to that area in what seems like a short amount of time. The fact that the phone says 100% when you unplug it is for effect. I used to always think I had battery problems, just stop being so worried about the battery and you'll notice an improvement. Hope this helped.

Also draining them completely flat, as in device won't power on, is the worst thing you can do to them
It sort of kills off a little of the capacity, every time you do it
So to the bloke that recommended it, no it does more damage than good

I'm finding turning to GSM only helps massively. I mean, so it should but I was hoping I didn't have to do this all the time, like I had to with my 3GS... And its a pain in the butt having to change it.
Still cant find a widget that will do it for me...not mobile data, ACTUAL WCDMA-GSM and back...
On the side, if anyone knows of one, please tell! haha
Thanks

I tell you is true, and i don't understand i either!!!
Most of the 17 houres the phone was only in standby and i only read mail twice.
I guess its just a fantastic ROM that Mike1986 has made with no Sense ;-)

I can get a day and a half out of my IncS with heavy use on a pretty regular basis. Set brightness to automatic, switch off unnecessary auto updates, GPS, bluetooth, and keep volume down or off in games. My screen timeout is 1 min (reduce for longer battery life), and I have always on internet switched off. I generally leave my Wi-Fi on a lot by mistake but don't find this to affect things too much really.
You will get 96% a lot after a charge as it is bad for your battery to stay plugged in when it's fully charged, so the s/w on HTC phone switch the charge off for a little while so it runs down a little and back up again. I had Hero before and that did this as well.

juice defender ultimate is excellent in my experience.
i had it set to switch on data every 5mins for 15secs to receive notifications and do updates (i have quite lot syncing - twitter, fb, sky news widgets x2, weather) and i would sometimes have gotten 30 hours out of the phone (ie. i wouldnt have charged it 2 nights in a row sometimes), but always easily 1 full day.
im getting sick of having to use JD though, because i figured something HAD to be wrong as my battery would drain in maybe 5-8 hours without JD which I just dont think is good enough and so could not be how its meant to be.
i then read about some people having problems with cyanogen rom battery drain, and that if you switch off android market notifications, it solves it.
so i tried it, charged my phone to 99% again and im now at 82% after 5 hours 10mins, which means if i keep using the phone at this rate, ill make it 25 hours - which is more than good enough for me. (~and i still have all the same stuff syncing as before, except market notifications~)
also i have wifi set to never sleep, so its always on. (its my ideal that everything that you buy the phone for should be able to be kept on 24/7, eg data, gps etc always on - so i keep them like that. bluetooth i dont use though - if i can make it through the day on a charge with decent use, im happy)
try it.
im calling BS on jkolner btw - pics or it didnt happen

Battery stats stay messed up

No matter how many times I calibrate my battery, it lasts for over 30 mins of straight youtube watching with 3g wifi bluetooth and gps on. I know there's no need to calibrate after the stat wiping after charging to 100% but I would like my battery to display correctly. The past two calibrations told me it was off by 8% but it did it twice not only once. So how can I get my battery to display correctly and not last forever sitting at 1%
Sent from my DROID3 using XDA App

Charge to 100% (leave on charger for 4-6 hours) then calibrate (remove batterystats.bin) then deplete battery until phone shuts off by itself, then charge without break to 100%.
Sent from my DROID3 using XDA App

There is no battery calibration. A google engineer has already ended that theory. The batterystats.bin updates everytime the phone is plugged in to charge. Dropping your battery to below 20% before charging is always a wise decision, but you can't calibrate it by deleting file.

I already stated that above but my phone can sit at 1% forever and not die so somethings obviously off
Sent from my DROID3 using XDA App

Obviously it's your battery.
The phone gets the %charge by the voltage. A good battery has a linear drop of voltage during use, but if a cell is defective, it can report a misleading voltage drop curve while still having enough charge to work. IF the battery drops under a determined voltage AND current, it shuts off. While both conditions aren't met, the phone keeps using it until a safe point, where it doesn't damage circuits or the battery itself

Sudden battery drain when at 10% and below

Recently I noticed sudden battery drain when 10% and below. It takes a couple of minutes while browsing or watching youtube battery goes down to 4% and then in a bout minutes goes down 1% and off. I am not sure when it started but my guess after JB 4.2 update. I am on three UK network.
Thanks

Don't know if it would help but you can try to calibrate the battery (actually the displaying of the percentage).
Charge your battery until it's full when the phone is on.
Disconnect it from charger.
Turn phone off.
Plug in charger and charge it until the LED turns green.
Disconnect charger, turn phone on and use it as usual (my desire needed a full discharging and charging cycle after that)

That's what I was thinking battery display might be off the rails a bit.
I will do it on the next charge then. Other than that battery does great job. 24h+

I get this aswell, on android revolution 12. It goes from 8% down to 1% and bam my phone is off. Really annoying

This exact same thing happened to me earlier today (ARHD 12.1). Very annoying. Is it a rom thing, or a battery calibration deal..?

i cant be sure, but it happened to me one time, so i use and app from playstore to calibrate the battery, and now it is ok,

Mine does the same thing, but it quickly goes from 5% to 1%. I assumed this was a normal feature to prevent the battery from draining completely, which is something you usually don't want to let happen. If that's the case though, HTC should have taken that last 5% into consideration when calibrating the battery.

I suggest you all should try that calibrating method and if that won't work, it's probably a defect of your phones

Has anyone else had any success at all with this
I'm running 4.3 GPE rom and I get excactly the same thing here, I don't think I had this before .... I've tried recalibrating the battery, doesn't make any difference, so frustrating.....

In your case I think it's just a calibration issue. I personally had the same issue with ARHD but it settled with 5-6 charging cycles.

Battery life

Hello guys i have bought a note 8 from 7 days and i have Seen that battery percentual decrease quickly. In the morning after some minutes with only display unlock i loose 5%.
Is this normal?
Thank you

Dude dont charge your phone to 100% over and over all the night. You cant remplace easily the battery. Dont worry about your battery drain, I thinks is ok. Normally we got 6-7 hours of screen on time, so if you only lose 5% in 30 min... it mean you can get around 10 hours!

I charge my phone on a wireless charger base overnight and it stops charging when at 100% and no problems! Anyway, if you read the latest thoughts on charging, keeping the battery over 60% is best and no damage will be done by over night charging!

The best for a litium battery is stay in 40-60 percent. Charging more than 80% will also damage your battery life (but sooo much less than let it drain to 0%). Charging over night isnt good for a battery (at least I think it). Check AccuBattery, is a very nice app to battery management. And when you hit the 100% it stops, but will run again because you wont get a 99% while the phone are in the pad. Hope I help you ^^

Do you monitor your data? You could have some apps working in the background and using both your data and battery. Install a data monitor app to check which apps use your data.

I get 1.5 to 2.5 % drain per hour in idle, gps wifi and data off, aod on, sometimes even 0.9% per hour overnight
