i need some help or advice of what to do to the battery after flashing a new ROM. do i need to discharge completely? or keep it on a charge? cuz after i flashed it the battery meter was inaccurate and like it went to 97 and after soft reset back to 99 and sometimes it would stick at a certain level for a long time then after wards i lose like 10% easy...can u guys help me out? thnx alot
Sometimes you don't need to do anything. If you notice the battery meter is inaccurate, then I would discharge it until the phone shuts off, then charge it completely with the phone OFF. Once the LED this is solid to indicate 100% charged, then turn it on. If you need a phone while its charging you could just take the SIM card out and use it in another phone.

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.
Your battery gauge is lying to you (and it's not such a bad thing)

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!
weird situation?
ok so yesturday i flashed over the new humble.
and well i left it charging iver night.
when i woke up my i disconnected the charger and took off.
when i checked my battery stat and what was using it.
my display was at 49%
i have never had it this low its always 75% and up.
and during the time.i had it down in the 40s. it hardly wasted any battery.
and now i restarted my phone and screen is back to 89% -.-
and i havent used it at all and ita been 4 hours and am down to 88% battery only with phon at idle in my pocket. ohh and i had data off..
wat is going on!?
You need to calibrate your battery. The easiest way to do it is to use the battery calibration app you can get from the Market. Put it on the charger and wait until it is 100%, and before you unplug it, run the calibration app and press the button. After it's done, take it off the charger. For best results, you need to then completely drain the phone without ever plugging it back in and then completely recharge it again without ever unplugging it. However, just doing the initial calibration will help you out a lot.
what do u mean the initial calibration?
and do u know why my display was really low? n stayed like that?
untill i rebooted
Hi all,
There's this problem with my phone that everytime I charge it, it takes an elongated time to do so. This issue first emerged when I was on stock GB after a minor OTA update which added the power saver toggle to the quick settings menu..The problem is that it takes about 4-5 hours to fully charge the phone, and if I rebooted in the middle of charging when it's about 70% or 80%, it suddenly shows that the phone is fully charged, and the indicator becomes green! But afterwards the battery drains as quickly!
Now I have S-Off and using ARHD 6.6.3 ROM, but it seems the problem persists ..I wiped battery stats as soon as I flashed the ROM as well..Although it's not a problem I cannot live with, it's annoying enough when it happens.
Can someone please help me? And suggest me what to do?

its common thing...the battery calibration is not proper that's all...
also you need to wipe stats once you charge your phone to 100%
then battery will try to calibrate ...and after 3-4 full complete cycles (100-0 and 0-100)
the battery will settle..
the battery drain will be there ...whenever you flash a rom or flash a kernel....battery only settles atleast after 2 full cycles
EDIT: also download currentwidget from market..as the name says its a widget..so you will see it in widgets once you installed it...this will give you more proper reading of battery...when you plug your phone to charge...and when current widget reads 0mah then your battery is charged completely...(it might take a long time to read 0mah...but charge it until you see 0mah)..then wipe the battery stats...so after this battery calibration will be proper
Also the sudden jump of battery percentage is due to improper battery calibration
so dont worry you got no problem
So
I read somewhere that you are not supposed to let the phone go to zero because it could cause your phone to not power back on anymore..is this fact. I couldn't find where I read it to back and read again. Mine has been doing some weird things as well...the led turns green before it is 100% and it goes from 100% and drops to like 89% out of no where.

when i meant 100%-0% means until your phone turns off due to less power..it might not(or won't be) be 0% then
as i told you that kind of jumps are common ...in my case it went to 60% to 100% when i rebooted ...also the dropping used to be in large scale too

Thanks mate! I will try this out! cheers!
Not sure what's happening with my phone, but after removing the plug on my fully charged phone, I will let my phone sit idle for about 10 mins, when I go wake the screen, I see that I've already lost 3% of battery capacity.
The weird part is after this initial 3% is gone, my battery will drain normally. Does this mean I need to calibrate my battery? Is there anyway to do this without damaging it?
It means you need to get a new hobby... seriously, why do you care if it changes nothing what so ever. In order to fix this, you should try not checking your battery percentage every 2 minutes. On the upside, this will probably give you another half hour of battery life as well.(damn a change of attitude would fix like 90% of problems on this site)
On a more serious note, it's likely just because your phone doesn't keep charging when it hits full charge, it stops charging in order to not kill your battery, and lets it drain to like 90% at which point it will charge back up to 100%, so it may be at any point in between when you disconnect it. Even if it is truly at 100% when you disconnect the charger, the measurements may not be completely accurate when approaching 100%, so it is likely, that could make it drop faster at first. You need to do nothing in order to fix this, seriously don't mess with it.

Are you running stock or custom kernel and any custom ROM? Ive noticed this sometimes too but that's because the phone, when unplugged is running services to start phone on battery power versus the cord/wall charger. Check logcats to see what happens when phone unplugged to see what may be happening when phone starts on battery.
I think you are worrying about it a little too much. It could be searching for service (which drains a lot of battery), starting services as someone previously said, heat is horrible for a battery, anything. If the drain is normal after that who knows it could be the ROM you are on, battery percentage not being reported correctly.
Not worth an RMA by any means. Reset battery stats in recovery and see how that works out for you.
Bear in mind, these batteries are cell batteries, a user who plugs their phone in every time the battery hits 50%, is going to notice over a period of time the time it takes to go from 100% to 50% is shorter and shorter, and suddenly, 49%-0 holds a better charge. If you're constantly charging your phone, you'll wear those cells of your battery down. This is where the "hoax" of always letting your battery drain to 0% when you get it to "maximize" battery potential came from.
Hello!
So my battery drops from 96% to 67% in 30 minutes. Sometimes the phone restart at 60% and the battery drops to 5%.My camera drain the battery instantly to 0%.If my phone is charging the battery acts normaly. My questions is what is the best way to recalibrate the battery?The factory reset will fix this,or updating with huruupdater?
My phone is rooted.
Thank you!
I forgot to say that the phone randomly restart but battery % remains the same and sometimes is charging very slow
Mine was doing the same thing. You will probably need to replace the battery. I bought one on ebay for $8. I followed a youtube tutorial. You will need a hair dryer, phone tools and alot of patience.

you need to purchase a new battery. calibration will not correct it.
I had the same issue, i can really one time i had to connect my power bank to take a picture lol
