Okay...?
The majority of the people here have rooted.

It won't help. I have deleted the batterystats on mine phone more than 20 times in the last 3 days and there is no change nor hope!

Let me rephrase by saying your ROOTED phones battery stats might be lying to you.
And for the guy who tried it three times and failed. I don't think you took the time for fully discharging the phone. That's right I'm calling BS.
Anyway got to go my battery just dropped 30%

Just wanted to let you guys know that this is completely true in my case. The other night around 2am I went to sleep with the battery around 68%. When I woke up 4hours later for work my phone was turned off. I then plugged it in and my battery was at 0%.
I was on the perfect storm Rom. I then switched to das bamf. Still happens. Tried bump charging and 0-100 charging and its helped but when I reboot the phone the battery shows about 7% less then where it was.

I think that is thy the stock battery icons don't show an exact %, b/c they haven't been able to make it work right. Don't worry though i believe that the devs will get it before HTC.

Ok my battery was just now at 50%. I restarted and now showing 41%. I don't know what's going on.

As I said, you can charge and discharge all day long, it won't help!

Thank you for reposting this. So sick and tired of people complaining about dropping 10% in a few minutes after a full charge.

I think this is a glitch. It drops like crazy after restart but then stays there until it "catches up" I guess.

So far,I have only rooted my phone, not a custom rom. I either have a crappy battery life, which seems better when I shut 4g down, or there is a glitch on the metering. My .02 worth.

Yes, this is true.... The LED turns green on 99% and never touches 100%. But i did not care much about it as I was more interested in flashing ROMS...though this is a problem.... I have also ordered Anker Batt... waiting for the courier...

I noticed mine did this last night. I just kept it plugged in and it eventually hit 100%. I took about 9 hours for it to hit 100%. Hope its not like that every time. Ill be finding out tomorrow.

well it hit 100 even when the led was green

I've noticed that the discharge is also a bit strange even on OEM battery. My battery varies very much. Sometimes when I reboot I get 5-10% more juice after boot without putting it to charge

yes same here....what can b causing it.....can it b smthing wrong in s-off procedure

Could it be something to do with the 2.3.3? Cause my battery acted strange even S-ON so I don't think it's the S-OFF procedure itself that caused this. Might be something something to do with battery drivers or something?

AFAIK Li-Ion batteries should never be charged to 100% because it shortens their life, most phones have a safety-mechanism to prevent overcharging.
Its intended to stop charging at 95% to 99%, but will almost always show that the battery is charged to 100% so the customer wont complain about it.
yes HTC is lieing to us, but for our own satisfaction.
So after we flashed the CWM recovery this "feature" is not there anymore and we can see the true charging state.
By plugging the power in and out over and over again to reach 100% you just damage your battery with those short charging cycles.
I read a interrestion thread about it in the Nexus S forums awhile ago and Wikipedia seems to confirm it.
I hope I could help you.

Battery dies then back to normal

I have an issue with my battery. Sometimes it starts to drain the battery VERY fast, like 80% in 20 minutes, then the battery dies and the phone turns off. But if I turn it on it starts with the ammount of battery it was before the crazy descharging, and the phone works as usual.
It is a pain in the ass because every night it happens, so I cannot set an alarm. Sometimes it happens in the day too.
It is upgraded to Android 4.0.4.
I forgot to say. I bought the phone and tried to update it. Something went wrong and the battery was low. So I coudnt use RSD tools anymore. So I opened the phone and did that force recharge thing to charge the phone up until it had enough energy to use RSD Tools again.

Might just need to clear battery stats. I'm guessing you didn't do a factory data reset after you took the update?

Hi. Yes I did a factory data/cache reset...
I cant see the pic i posted, so I will put here the link of it in google docs:

Hmmm. If you've done a full reset then it looks like it's an issue caused by the update itself. I've never seen a battery graph that looks like that.

its better to use battery calibrator app from market and use and u can also make 3 complete charge and discharge cycles and see ......if it still doesn't work then it should be a bad battery ......replace it
CHEERS
HIT THANKS BUTTON IF I HAVE HELPED

you should replace your battery

It's been shown that all of that multiple calibration mess is bunk. Except in the case of errors battery stats are cleared on reboot anyway.

A new battery would be a better option, ok try one thing , take off the battery and keep it in the sun for 2 hours, then charge it full .. Use this.. N seee

I had a similar problem with my second thunderbolt. Finally I replaced the battery and problem was solved.

The think you msut do is to replace your battery. Nothing else would work for a long time..

[Q] Insane battery drain from Android OS

So while charging, phone is extremely warm...
I pulled it off the charger last night and 2 in the morning, went to check time and it was dead when I woke up.
I plugged it in 4 hours ago, and it's only gone up to 91% also.
I also don't have my sd card to micro usb doodad to pull the backup.... -_-
What causes this type of drain?

Reboot it. Also leave ROM and kernel in reply.

If the problem survives a reboot then worry about it.

I rebooted last night, and unplugged it to see the drain. At 8 in the morning it was at 30%. I'm just waiting for it charge so I can test again. It's 96% now though.
I have Mahdi rom, and mahdi kernel for the newest update.
Last night I had Uber kernel and Mahdi rom 2.7.

And the phone was at 100... It's still draining.

[Q] phone shuts off before 0%

Hi, Is there any full proof method of fixing my phone battery so it shuts off at 0%?
My bacon shuts down at 8% - 4% usually.
and when it does shut down it blacks out. I don't get that pop up with a spinning circle saying you're phone is not shutting off.
Well, unless thats how the OPO shuts off by just immediately blacking out?
I checked to see if it was because my undervolt, so i brought back the voltages to stock, and unfortunately, the problem still remained.
I know you arent suppose to run these batteries dry, but it just irritates me that it would shut down at the 8% mark.
So any suggestions and fixes would be greatly appreciated!
Thanks

If you know that, then why the hell would you want to do it just so that you damage the non-replacable battery and potentially leave yourself with a brick?

The battery percentage displayed on your phone isn't exact, not at all, it's only an estimate based on the voltage level it's detecting at the battery. So if your phone shuts down at 4% it really isn't a big deal. If it's bugging you so much you can use a battery calibration app from the Play Store to try to re-calibrate the battery.
But, if you're letting the device get that low regularly, which it seems like you are, you're damaging the battery. You even admit that you're aware of this. So why do it? Running a lithium battery down regularly decreases its capacity, just like keeping it at peak voltage too much does too. So it's entirely possible that what you're experiencing is a symptom of your own bad battery usage behavior.

Gee, I don't know
Maybe I like to see a full screen on time, testing kernels and roms?
or maybe, I didn't expect my phone to shut down at 8%, so I wanted to see if it wasn't just a one time thing because the unknown piques human curiosity
Maybe as a newer model phone, I'm putting some faith into solid build materials from the phone?
My nexus 4 has been run down many times naturally being at school or work and what not, and the battery still runs like a champ.
