Battery fast charge and discharge - Desire Q&A, Help & Troubleshooting

I have prolem that phone discharges normaly from 100% to some 70% and then rapidly discharges from 70% to zero. Batt graf shows vertical discharge.
Similar thing when charging. It charges to some 30% for an hour and than from 30% to 100% in a minute.
I have read tons of threads, did batt cal, delete batt stats when bat was 100% and when batt was 0 % few times, did s-off, change bootloader, tried few roms. Always the same.
Is this behaviour because batt is dead? I dont have spare batt so before ordering new one I want to ask did somebody experience similar situation?
Thanks.

upload the graph, how old is the battery?

You can try another ROM and look if the problem persists though I guess that's not a problem of any ROM... I think it's the battery.

I will try to upload graph. I have screenshot of charging graph but I must dischage battery again and take screenshot because there is no discharging graph after wiping bat stats.
P.S. I have also try to charge while on, then turn it off, charge again etc. I found some manual.

Android OS stays awake and kills my battery

So I have unbricked my phone and have flashed cm9 and fullthrottle now I'm on the official ics from att. My phone has been dying quickly. I checked my battery stats and seen android OS in my number 2 spot. Today I unplugged my phone and didn't use it for two hrs and it went down 5% I checked and android os stayed away 1 hr and 53 mins.

You need to install the better battery stats app and see which app is giving you wake locks.

Yep, install better battery stat, it's even free for XDA member, search the app forum.

Also, there's a thread called "known identified battery drainers" in the ATT GS2/I777 forums that has some good, universal stuff on interpreting wakelocks.

any luck solving this?
I tried flashing this from 3 times wiping everything and still get the android os taking most of my battery. I tried better battery stats but can really interpret it. I don't have facebook link or instagram. I'll post pics of better battery stats.

Did you flash through CWM or using LG's official tool from a computer?

I'd suggest disabling stock apps you don't need, I guess. Most people seem to think the battery life on that ROM is decent.
I always disable the att apps that come with the stock from. I get about 10 hrs on medium use with the extended battery. If this was fixed then I would get way more

same issue
I never even thought to check into that as I have also had bad battery life, but figured it was just the nitro. New to rooting LG's as I had samsungs before. I am having the same exact issue running OH!NO! Full Throttle 7.1 and never realized it.. Is it just settings that are not allowing it to sleep?
I have no clue but there is something that is keeping the phone awake and not letting gp to sleep which is really hurting the battery life
Sent from my LG-P930 using xda app-developers app
i definitely recommend getting juice defender. it made a HUGE difference in my battery life.
I tried it but it didn't help much just turned off the data. The only thing that really helped was to go into app settings and disable android and it has helped some

I have the same issue. Android OS is (or was) the best battery killer. AT&T support person told me to do factory reset AND DO NOT INSTALL any app that are not preinstalled. I have to install them later one by one to find one incompatible with ICS.
After reset operation (happened 2 hours before) I have now Screen as the best battery killer Battery went from 77% down to 62% with some browsing and preinstalled apps update. It looks promising...

Battery percentage increments?

Does anyone know what percentage the battery decreases at? Like does the icon decrease by 5 percent, 1 percent, etc.

Something might be draining your battery.
Even I've noticed many times, battery gets decreased while charging and playing games. Please don't use your mobile while charging. It can effectively improve the time it gets fully charged.
It's been my personal experience.
Or put in airplane mode over night to charge it effectively.
Sent from my LT26i using xda premium
you can change an USB line
if no use, put mobile in airplane mode or shutdown to charge

Problems with ZVB

Is anyone having battery issues with the update I didn't wait for mine and flashed it about a week or so before I was due for the update and my phone turns off when the battery is around 15 or 20 percent. The sprint animation doesn't come up it just dies and then I can't turn it back on while unless I plug it in and the white battery symbol shows up then I have to wait like 20 minutes to turn it in and it will turn on with about 3 to 5 percent battery. Does anyone know what's up or if this is normal with this phone.
Sent from my LG-LS970 using xda app-developers app
Doesn't sound normal to me. I've run mine down to 5% before on stock. Bad battery perhaps?
I'm not sure on the battery settings it says it has good health status so I'm not sure...
Sent from my LG-LS970 using xda app-developers app
If I were you try these few things.
Make sure the charger is working correctly.
See if there is an app killing the battery.
Try and see if the stock power save mode helps.
Try clearing the cache and rebooting.
And if all else fails do a clean install on LGNPST. This usually fixes most issues.

Battery Issue

Okay at first I thought that i was having issues with the roms that would drain my battery but it always on slow charge, I tried so many different usb & wall chargers all the same & even when I have my phone on, the battery drains fast. Does anyone know how to fix this besides getting a new battery?

Are you trying different charge cables? That can make a difference.
Also... See my post here. http://forum.xda-developers.com/showthread.php?p=49155732

My battery also drain so fast when using stock rom or custom ones.
Is that because too often trickle charging?

That happened to me and I got it back to normal by changing the CPU settings to interactive.

I have used different wires still no change. So irritating to always have to charge my phone. Especially when i have to turn it completely off to charge & it charges slow.
Hmmm so change the cpu to interactive?

are you using the original charger that came with the phone or is it a generic charger? I had this problem with my previous phone, lg optimus l9. I used different generic chargers and a samsung charger and kept having the problem so I ordered an lg oem charger and it charged fine and didn't drain the battery after that. and try this battery app instead, betterbatterystats. you can download it for free here http://forum.xda-developers.com/showthread.php?t=1179809
I used them both generic & the one it came with but they are all the usb kind. It so frustrating... Thanks for the app advice i'm going to try it out & hope it works.
