I replaced the battery on my G7 a few months ago. I let is sit for a week while I was in the hospital, and when I came home, it was on 0% and will not charge. Any thoughts? I'd like to at least get it on long enough to wipe it cause I'm not replacing the battery again.

ok, over the last week or so ive had this issue, gradually getting worse...
my battery will charge to around 40-45% and then charging will slow right down.
two hours later, it will be on around 50% if im lucky, and about 3 more further hours before i hit 60% (this is some of the time, other times, it just remains on its current charge%)
if i leave it overnight for about 10hours or so, highest it goes to now is about 73%, but this is rare, usually 45-50%ish.
ive tested with htc ac wall charger, htc usb, blackberry charger, car charger and a random microusb wallcharger. all have same issue.
when tested with two friends desire hd's on different days, my battery charged perfectly, and at the normal gradient speed over the % range. and my phone reads it correctly at the 100%-98% when back in my phone after change back.
i thought it was down to my phone, just dont know if its rom or hardware. shud i factory restore, or claim on insurance?
i have another issue here...http://forum.xda-developers.com/showthread.php?p=18480603&posted=1#post18480603
which also applies to the question of restore or insurance...
thanks
What Rom are you using, i am using runny 2.2 only 62% charge in 6 hours
9 hours later on battery only upto 68% i have amazing battery life now
i'm using runny 2.2.....left it on charge for 2 hours with phone on, but wifi and everything off and it had only gone up 2% ! !
Turned phone off and plugged in charger, 30 mins later, only went up 1% ! !
72% charge at this point.
So took it off charge, put it in my pocket, went upstairs to bed, turned it on to set alarm and it said 100% on battery....weird!!

Lol this is an issue with calibration. The battery is charging but the software doesnt report it.
You have to charge the phone for as long as possible so you know it is on 100% whether the software says it or not, go into CWM, wipe the battery stats and then let the battery drain fully until it shuts down by itself. Then plug it in and leave it until you know for certain it is at 100%. If the green light comes on leave it for an additional half an hour. Then it will be fixed.
ive only recently got this handset, as last one was replaced on insurance a month or so ago, and its runuing on stock rom with latest updates....?
I bought my Gnex from Handtec at the end of November. I have been very happy with it Until 2 weeks ago. Battery life has not been great but has lasted 16+ hours each day and I always charge overnight so this has not been a problem to me.
I take phone off charge at 7am. A couple of weeks ago I started to notice that instead of 50% at 7pm it was showing only 20 to 30% charge.
I bought BetterBatteryStats which showed no WaveLocks.
I started to freeze apps using Titanium Backup.
The battery life did not improve. I noticed the phone was getting noticeably hot to the side of the camera and charges were taking much longer. Instead of 3 hours it was taking longer than 7 hours.
Last weekend I noticed a drop of 70% in 3 hours on 2 occasions.
So I decided to wipe the phone and install AOKP build 15 with Franco kernel 10. I did not re-install aps. I charged he phone after install which took all night and then reset the battery stats.
The phone has continued to be hot and discharge very quickly. Charging is very slow. If the phone is off - charging appears to be even slower or not take place at all.
My Gnex is now fully discharging in less than 5 hours when idle in flight mode and is always very warm without any use.
I have been using a Samsung galaxy s2 wall charger.
Is this likely to be a faulty battery or phone hardware fault.
Any suggestions for next steps or is it a Samsung repair job.
Thanks

well, whichever it is, it sounds like a hardware problem that should be warrantied. i would flash it to stock and get it repaired by samsung, or see if the place you bought it will take it back
I get a similar problem but i return it back to vodafone 2 days ago and now waiting for the results, i returned it a week ago and they only give me a new battery to see if that will solved the problem but nope it persist, now they too it for either repair or replace ....

I am on the same build and recently used francos kernel. At night the phone would drop 20-30% of battery on airplane mode. Installed the apex build 5 kernel and all the battery nonsense stopped straight away. It seems to be a great kernel especially with AOKP B15.
Hope that helps.
Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.
In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!
It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.
What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?
BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)
So my phone battery has been acting crazy since the last update. First it dropped to 0% instantly from a 30 or 40% a weeks ago and just now it went from 20% to 0 in a second. The battery doesn't seem to be bulging. So before I buy a new one, has anyone else had weird issues? Just now I was charging it and decided to take out the battery. It jumped from 14% to 55% charge instantly from reinserting the battery.

It's a bad battery. There have been many people coming on here describing your same symptoms, but it doesn't matter what update they're on. In the end, it always turned out to be a bad battery.
So it's not an update issue.

I have had same issues and I noticed it's beacuse I was charging my phone via portable power bank.
When this happens I just drain battery dead, recharge phone to 100% while its turned OFF.
Unplug the cable, turn it on, if it doesn't show 100%, I just plug the charger again to refill it to 100%.
After that for several chargers no problem, it goes slowly to 1% and then dies on 0%
As I wrote in the title, my phone battery percentage suddenly dropped like that in a mere 5 seconds or so.
This isn't the first time this happened, but it doesn't happen on a daily basis. This happened to me 2 other times
in the past month, it once dropped from 11 to 0% and from 8% to 0%. Is the battery dying? Is there anything I could
try or should I just send it to the warranty service? (I have it since like 11 months, so it's still under warranty).
I too have the same problem. After reaching 20% the battery comes down to 0% in 5 seconds and the phone shuts down

I had the same thing, dropped from 15% -> 8% -> 0% and shut off. Batteries don't last forever; I've had this phone for 14 months.
Try to charging phone from 0% in shutdown condition for 8 hours.

I've had other phones before this which I used for at least 2 years each and never had this kind of problem. First time it happens to me on an android phone.
As for the time since I have it, it's 11 months. Tried anything I could (calibration, charging while the phone is off,factory reset etc) and it didn't work.
In the end I went to the service center with it.
your battery is being "voltage depression" , I don't know the English mean but it like: "Weak battery" or "battery won't hold charge". Just to replace a new battery, all will be okay
