Defective thunderbolt battery?

Good Morning everybody!
I think I have a defective thunderbolt battery, sometimes when I pull my phone off the charger it drops to 95%. Funny thing this is not a everyday thing. Anybody having a similar problem like this? Sorry if this been discuss before. Have a bless day everybody...on my way to the office.

I have the same thing happen. There is something goofy with how the meter reports battery level. If you reboot your phone it drops even more.

Yea I notice that too. I seen my battery drop down 15 percent after rebooting. Is the battery defective? Or the phone is defective?

Bump charge it. Charge it all the way. Unplug, turn it off, then on, and keep charging.

The phone/battery aren't defective. I have the extended battery so I never bump charge it, but he is right. Charge it up until your charging light goes green, unplug it and then turn it off. Once it shuts down, plug it back in and will now be orange. Charge it until it's green again. Sometimes it will take a few minutes, sometimes an hour. I'm also color blind so I can never tell whether that damned light is red/orange/green. >.<

He gonna have to turn it on then plug the charger in. If left off then plugged in the phone will boot into recovery.

charge ur batt. to 100%, then go into cwm and clear batt. stats, when u turn it back on it should b around 80-85% then charge all the way back full again and then u will b at full capacity

is this all the time we have to do, I have the extended battery and it doesnt drop and I read about clearing the batterystats.bin but is this something we always have to do when we charge the phone? when I use the standard stock battery it drops with no problem

I didn't have any issues until I wiped the battery stats and now, my battery is constantly inconsistent. I would not recommend doing it as it has nothing but a pain in my arse since.
Have tried "bumping it" which essentially means to charge it to 100%, restart it, then charge it back again from whatever it dropped to.. Mine initially was around 85ish.. After a few "bumps" it crept up to 90 or 91 and then wouldn't go any higher. I charged it back to 100% and decided to follow the advice from another article which said to let it deplete to 0%.. In doing that, surprisingly it "froze" in a couple of places, I don't recall the 1st % but the 2nd % was definitely at the 28% mark. It literally sat there for a good 2+ hours with screen on max and didn't go down. Eventually it went down to 1% and I charged it back to 100%.
Issues still remain, wondering if I should've let it completely die out and force itself off?
Lesson: DO NOT MESS WITH BATTERY STATS with CW.

Where do I get into CWM, to do this?

Thanks for your help everybody! I'm sorry if this is a dumb question...what is CWM? My device is stock.

CWM = Clockwork Mod.. Goto Market, download ROM manager, then you can flash CWM. Not sure if that'll do you any good if you're not rooted though.

why when I reboot my phone like 15% of the battery life drops I love this damn phone man...i cant put it down while im at work

The battery reading after reboot is wierd.
Yesterday I was at 51% and draining are at a pretty steady rate like normal. After rebooting, it showed 41% but then it say at 41% for AWHILE.. after like an hour, it read 40% and started discharging at the normal rate.

Thanks for the repost, I had skimmed this thread earlier but don't recall it being so detailed. Seems like the moral of the story is that while "bump charging" works, it's not really recommended as it can reduce the overall life of the battery. Wonderful, now I regret ever messing with the battery stats at all, although I can't say for sure I didn't have this issue prior to doing so.

My OEM battery wouldn't hold a charge even after charging it all day... I took it to the VZ store and they replaced it for free...... I also just bought the larger 2750 mAh battery.... works great!

[Q] Battery Lag?

Hey guys, I have a problem with my Sensation. Whenever I fully charge it and then remove it from the charger, use it for like an hour or two, the phone still thinks the battery is 100% charged. When looking inside the battery usage, it shows the graph with 0s underneath it, while in the previous screen where you see the apps battery usage it says 2h 5m 13s or something like that.
This wouldn't really be a problem, but when I started up Maps Navigation and plugged the charger in the car, it wouldn't charge because it still assumed the battery was 100% charged!
Any of you also having this problem? Thanks in advance!

Does it stay 100% forever? Then you may have the inexhaustible battery... (not sure if this is grammaticaly correct )
I wouldn't consider this a problem. You can download a battery monitoring app from the market and see what's going on with your phone and if the 100% that it's rerporting is correct. Also, check that the battery contacts are clean.

Not sure my phone does that but it can be on half charge then when I reset phone it's gone up a notch. This morning it didn't look like it had charged although it had been plugged in. When I switched it was on orange then it did the charging animation for a few seconds without charger plugged in then stopped on full. Odd.

Mine stays on 100% for a couple of hours too, has done since I got it.
I think perhaps HTC are "cheating" (or using "creative coding", whichever expression you prefer) in the way they report the battery percentage. Make the battery appear better than it is. Just a theory, of course.

That happens to me a lot too. Woke up this morning, phone had been charging for nearly 5 hours, but was only on 82%. After a couple of minutes of the screen being on, it had leapt to 100% and stopped charging.
Also, once the battery is below about 20%, it will sometimes drop 2-3% at a time. Odd.

Looks like they totally screwed the battery meter hardware or something in the software. Remembers me of my iPod touch

Experienced the say.. hopefully either it will auto be fine due to charge cycle or via updates

The Battery driver that LG used for the G2X has the same problem,a simple reboot fixes it,hope this helps "temporarily" that is.Cheers

Not just the sensation - my wildfire does the same yet my galaxy tab doesnt

Thanks for your answer, so it's probably a general problem that may be fixed by either HTC or the Cooks that make ROM's for our beautiful new phones

Can you tell me how long it takes for your phone to fully charge?My phone needs 3-4 hours to fully charge..is this normal?!

Hmm mine doesn`t lag but it takes times to charge. Usually with my hd2 take around less than 2 hours to fully charge now with sensation around 3 hours

Using it almost half an hour,battery felt from 100% to 99%...And I checked the battery useage,it isn't wrong..

I received my phone yesterday and charged it for 4-5 hours throughout the day. Last night it was close to 100% while I was playing with it (off the charger). I then charged it over night for 9 hours. This morning the battery says it's at 50% but has 15 hours left.
Weird :\

Charge the battery with the power turned off overnight, in the morning unplug the charger, turn the phone on, and shutdown again, and plug the charger back for 30
mins phone still turned off. After that start using the phone normally, this way you calibrate the phones battery meter properly.

Thanks mate! I'll do that tonight

Bump Charging has helped!

ok, so I'm running faux's rom and I have run CM 7. I have tested this a few times and each rom and it seems to help improve battery life.
Since the drivers are screwy I noticed when I charged my phone it would say 100% but I would unplug it and it would drop down to 97% right away. I think the lower number is the accurate one, So the battery really isnt getting fully charged because the phone thinks it is so of course it will die sooner
So what I did was let it charge to 100% then unplugged it, it went down right away. I plugged it back in and it started charging again, in a few minutes it showed 100%, I unplugged and it showed 97%, so I kept repeating this then eventually I unplugged and it was 98%, then eventually 99%. After doing this my battery lasted a lot longer. I usually have keep an extra battery on me and usually have to switch but for the first time my g2x lasted the whole day! So give this a shot.. it could help if you suffer from really bad battery life.

Off topic.
Im From Southern California...be visiting New York on Monday. Good stuff...small world some times.

could unplug, then turn off, plug in and charge while off for a while, the unplug and turn on, then plug back in and let charge. then wipe batt stats and unplug. works for me.

I have one extra battery. I never charged my phone through the charger it came with. I always charge my battery with the portable charger. No doubt the portable charger takes 6-8 hours to fully charge my battery, but on the upside my battery lasts for more than a day.

I noticed a similar thing recently. I generally charge my phone overnight while I'm sleeping and use it for an alarm clock. One morning I decided to reboot my phone (my experience is that it needs a reboot every couple of days or various things stop working) before I got up, so I powered it down, still plugged into the charger. I then tried to power it on, but instead of the boot screen I got the device-off charging animation, indicating that it wasn't fully charged, even though it had said 100% before I powered it off. After letting it sit and charge while off for another hour or so, I booted it, and I think I got exceptionally long battery life that day (although my days are all so different it's hard to compare one to another).

I think bump charging does help, but its not good for your battery in the long run

Overcharging the battery?

Is it possible to overcharge the battery? I ask because when I first got the phone and fully charged it, it would stay on 100% for at least a couple hours (using circle battery widget which reads in increments of 1%) but one night I fell asleep with it plugged into the charger and when I got up it still read 100% but as soon as I unplugged it it went immediately to 99%. I have not yet been able to get it to read 100% unless its connected to the charger. Think I could get the batt replaced under warranty since its only 2-3 weeks old?

Your battery is fine, it is set up so that it will not overcharge. I tried searching for an article that explained how the system is set up but couldnt find it.

I'll look in to that. But what about the battery immediately dropping to 99% when I take it off the charger?
sent from my Motorola Atrix 2 via Tapatalk

Every android phone I've had has dropped like that as soon as I've taken it off charge, nothing to really worry about.

They do a think called power cycling. It will charge it to 100% then shut off then once it goes back down it will charge it to 100% again. Ill try to find the article. Your battery is fine.

Weird. My SE Xperia X10 didn't do that, it would stay at 100% for at least an hour. I recalibrated my battery a couple days ago, thinking it would remedy this "problem" and after it died on me I charged it back to 100% and took it off the charger at 10pm, set my alarm on it and let it sit overnight. After pressing snooze on my phone 3 times and finally getting up at 630am it still was at 100%! So it's strange to me that this drops to 99% immediately but if it's happening to everyone else I won't worry too much.

Well if I were to judge off that, mine stays at 100% for hours......im going on 7hrs right now. But I use battery circle widget which reads in 1% increments......as soon as my phone comes off the charger it goes straight to 99%......it didnt do that before.

Battery Charging & calibration query
What difference does it make if you charge from empty to 100% in switched off stage and the same in on state? Which is better? How should we calibrate the battery and how often using which app for unrooted MB865 Asia retail? Also if phone dies (switches off) constantly due to insufficient charge does it harm the battery in terms of cells getting destroyed gradually & finally does switching off or switching on the phone while charging have any effect issue on phone or the battery?? Thanks in advance for inputs for all queries.

Battery discharging while OFF while on plane.

I got on a plane heading from New Orleans to San Francisco via Las Vegas. I turned my phone off just before boarding and didn't turn it on again until I landed in San Francisco. My battery was nearly fully charged as It had only been off the charger for about an hour and I wasn't using it. When I turned it on in San Francisco 7 hours later, it was nearly dead, with only 20% charge. I definitely saw the power off animation. It was definitely off when I took it out of my pocket, but the battery use told me the screen had used up most of the charge. What the hell happened? Has this happened to anyone else?
As a precaution, on the return flight I pulled the battery after powering down. I did not have any battery drain on the flight home after the battery pull.

Maybe the shutdown animation took a very long time and kept the screen on.
I have never heard of this, so I have no idea.

I've had this happen to me a few times. I power off my (fully charged) Charge at night before going up to bed and when I come back down in the morning and power up (and it goes through the power up cycle) I find I have limited battery left. I haven't tried to track down what is happening since I simply replace the battery with a fully charged one and continue on with my day.

I found that I had some file on my SD Card was draining my battery.

I don't suppose you remember which file that would have been.
So when the Charge is powered off it really isn't powered off?

I think it's just a glitch of the battery meter. Either it was lying to you when it was full or lying when it was 20%. If it doesn't happen on a regular basis then the battery should be fine, right?
I think we've all had it happen (at least to me a few times) where I switch out batteries that I know have been charged and the phone says that it's dead. The solution I found was to take the battery out and try to power it on, then put it back in or put in the fresh one. I don't know why, but it seems to get rid of some sort of bad juju.

Actually when my phone glitches out and reboots sometimes it shows the battery level more than 50% below what it used to be when it died. A glitch in the kernel that reports the battery level could be the culprit.
