How-to Train your Dragon[Battery] - Epic 4G Android Development

To help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, I tested this on my pops evo and my epic...MAJOR DIFFERENCE
After installing a new Kernel it is recommended tat you recalibrate our battery to get the most life out of your battery. I suggest using Phoenix kernel but your a grown man[or woman] choose your kernel
Hope this helps
Thx to bigdbag for these additional steps

My god. I was highly skeptical of this but I tried a quick version of the instructions.
I did the following:
1. Charge to 100% while phone = ON
2. Once at 100%, unplug charger and turn phone OFF
3. Plug in charger for 5 minutes while phone = OFF
4. Unplug charger and turn phone ON
5. Leave phone ON for 5 minutes
6. Plug in charger for 5 minutes while phone = OFF
and the results... are miraculous. I'm running Phoenix Kernel v.1.43 and stock rom w/ drm removed.

Trick trick trick trickle charge Battery is in fast charge mode when it begins charging from a certain percentage (although slow). When the charge is in the 90's and you unplug and plug it back in it trickle charges to completion. This does indeed work. Works best in my opinion when you do this after you let the battery completely drain, plug in, recovery mode, wipe battery stats and then turn on.
And then do what you stated above.

Yes!!!!!!!!
Totally gonna do this since my battery seems to be on the down side compared to everyone else's. :]

i also reccomend an external battery charger that u place the battery into. no need for the trick. Ive used this trick before i got the external charger and yes it does work very well!

+1 on the ext charger. I have two batt. If I charge with the phone... one- goes from 100 to 97 withing sec from when I unplug it and two- it doesn't last as long. Using the charge and switching out the batts. Stays at 100 for a while and it will last forever too.

I noticed this as well, so when my indicator LED turns blue and it says 100%, I unplug, then immediately plug back in until blue.. lather rinse repeat.. after about 3 or 4 times it finally stays at 100% when unplugged..
That being said, I'm gonna have to try to find an external charger and another battery...

My local sprint store sells a charger with extra battery for $49.99. Its an external charger that fits in your pocket. With charging cord of course.

tried this, doesnt' seem to work for me. I unplugged, turned phone off, and charged, but phone said fully charged after like 15 minutes, I assume once it says 100% on the green battery that shows up when phone is off that I shouldn't just let it sit there? its not charging at that point anymore is it?
then i unplugged, turned on phone, waited 2 minutes, turned off, charged again, 15 minutes or so it was fully charged again.

This reminds me of the chargobics that some ppl did on their evo to get better battery life....never really helped me.

So what you're suggesting (re: recovery/battery stats) is the following:
1. use the phone until the battery completely dies.
2. plug the phone in
3. boot into recovery (clockwork ?)
4. wipe battery stats
5. turn the phone on
6. do the 'plug me in' dance after it's fully charged
What if the battery is fully charged and you wipe the battery stats ?

idk i think i used to do something similar on my Hero and even back on my (WinMo) Mogul and Touch Pro and never really got much out of it......
However, today I did this and I swear I'm getting great battery life today. Have never gotten past 12 hours and I'm currently sitting at about 40% left at 12 hours. Could be the placebo effect but we'll see..... even played some angry birds today.

FTW!!!
Took 11 days to get here, but worth EVERY penny. I never need to worry about to battery life anymore. Hell, now that I charge my batteries using the external charger, I get atleast 8-10 hours with constant use, and my battery doesn't drop from 100 right away. I never get to the 3rd battery by the end of the day and thats with a 18 hour day unplugged. Worth it.

I have noticed some weirdness with the battery. I looked at the juiceplotter graph after the battery had been left charging all night, and it would charge to 100 and then over th course of half an hour drop down to 95% or so and then recharge up to 100 over and over and over again. I have taken it off the charger sometimes and the battery has gone from 100% to 96 % within a couple minutes and other times it stays at 100% for over an hour. It was a matter of luck as to when I pulled my phone off I guess, when it was really at 100% or really at 95-97% or anywhere inbetween.
Gonna try this PITA method of charging. Hope it works, but damn is it inconvenient.

The external battery charger is the way to go. i have also noticed when i rarely charge from the phone that it sometimes wont stay at 100 but for a minute then drop to 97. i get 55 hours to one battery with moderate usage.

This didnt really do anything. Unplugged from my charger at 1:50pm, its been exactly 2 hours and its at 77%. Mostly my phone was in my pocket, and I did very light browsing over 3g (maybe 10 minutes).
I'm on Latest Epic Experience with Mixup Kernel. And I don't have OC widget or Setcpu.

Is it really that much better? If so, what causes it to be better on battery life? I am getting great battery life using the mixup kernel because I have juicedefender and setcpu working hard to conserve battery life. Would Phoenix make a difference?

Just a FYI, Lithium-Ion batteries don't hold a memory like NiCad batteries did. It is also NOT good to drain them all the way down.

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.
Sent from my ADR6400L using XDA Premium App
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.
Sent from my ADR6400L using XDA App
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. >.<

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?

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

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?!

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.

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

[HOW-TO] - Battery Calibration

There has been much confusion and frustration surrounding our battery life and these custom roms. Some of us have great battery while others are having horrid problems.
I am writing this guide in the hopes it will help all of you with problems getting that great battery life.
This is a guide written from my own experience and technical understanding.
First, Your phone should drain, on average, 1% per hour or less while in standby mode (screen off). If you are not getting this average, you need to calibrate your battery.
ALWAYS flash a new rom with your phone at 100% battery - no exceptions!
i know some guides say to run battery down to 2% and then charge, but i never had much luck with this.
1) Before you flash your rom, charge your battery to 100% with the phone ON.
2) Once it says fully charged, turn the phone off and plug it in and wait for the on screen display to say 100% (this will take 5 to 10 min)
3) Turn the phone back on, and plug it in and charge till it says 100%
4) turn off the phone and charge again while off until the on screen battery indicator says 100% (again this will take 5 to 10 min)
5) repeat steps 1 thru 4 as many times as you feel comfortable, I recommend at least twice (I do it 3 times)
6) when you are satisfied with the charge, and the phone is still OFF with the indicator saying 100%, unplug the phone, remove the battery, and place the phone in download mode (hold vol down and plug into the PC)
7) flash your package (this is done in odin with the battery removed)
8) The first boot after the flash needs to be into Clockwork Recovery, wipe battery stats at this time (most roms will boot into recovery automatically, if not, boot into recovery manually)
9) after you have wiped your battery stats, wipe cache and other data (if the rom you are flashing requires this, if not, skip this step)
10) Boot the rom to the homescreen.
11) from this point on, you will use your phone like normal until the phone completely shuts off. this SHOULD take a while. you should see improved battery life during this stage. If not, dont panic, just run the battery down until the phone shuts off
12) once the phone shuts off (try to time this to happen at bedtime) plug the phone in and allow it to charge in the OFF position
13) once it is at 100% again, use the phone like normal and enjoy your new battery life.
IF YOU ARE DOING THIS WHILE NOT FLASHING A NEW ROM
Do steps 1-4 as many times as needed, I recommend at least twice, i do this 3 times
on the last charge up (your phone should be off while charging during this step) unplug the phone and boot directly into recovery and wipe battery stats. then proceed with the rest of the guide.
TO TEST THIS
charge to phone to 100%, try not to mess with it for an hour or so.. (light usage at most) you should still be at 100% or 99% after an hour. If you are at 95% or below, then the calibration has failed. (unless you have been using the phone or are in a very low to no signal area).
this calibration method is crucial to good battery life. Before I started doing this i was getting very bad battery life. Click on my username and look at my previous posts.. you will read about me *****ing badly about my battery, this is what I did and it has worked amazingly well.
I hope this helps
I combined a lot of techniques ive seen in other threads and some websites and then created this technique which seems to work really well.
I have used this technique and can confirm, it works well if done properly.

Are the first few steps what is referred to as "bump charging"?
I think this has worked quite well. I flashed Humble 1.2 (at 40% battery) last night, charged up, then started this procedure. After I got done, I took it off the charger and after 15 minutes of trying a new game, listening to a minute of music, and checking various things, I was still at 100%. i left it off, went to bed with wi-fi on, and woke up at 95%. Awesome. My all-day phone is back.

For all of you that are getting the great life, what percentage does it list for display? This is under settings > about phone > battery use.
I'll have to try this method. My battery life is actually worse now after I tried doing the drain to 2% method. I'll report back with my observations.
Are we talking 3G or 4G here?
I would find it useful when people are talking about how good (or bad) their battery life is to know if they are in a 4G area and have 4G turned on, or are they using 3G only?
Trying to figure out how bad a hit 4G takes on my phone...

So I tried this out yesterday...I don't have a rooted phone so I could not wipe battery stats (does anyone know how to do this without rooting your phone?)...but I did follow steps 1-4 three times and I have gone 23 hours on my charge without having to plug it in. I am in a 4g area and had 4g and background services on for the full 23 hours. Had bluetooth, GPS, and wifi turned off. I sent a couple texts, used whatsapp to send texts, used google voice to send texts, made 3 phone calls (about 4 to 5 min each) played angry birds for about 20 min, played words with friends for 10 min, surfed the web on and off, was on tapatalk and browsing forums for about 20 min and I installed a new keyboard and web browser on my phone in those 23 hours.
I am very curious to know if this will improve battery life after that first initial bump charge.
If you do a regular charge after depleting the charge, do you still see improved battery life?

I'll try another battery... but I've already been through too many DC's and I'm not returning this one. I have no issues with it at all, just this battery problem.

6) when you are satisfied with the charge, and the phone is still OFF with the indicator saying 100%, unplug the phone, remove the battery, and place the phone in download mode (hold vol down and plug into the PC)
7) flash your package (this is done in odin with the battery removed
I dont understand this, you can go to download mode without battery? Or flash a rom with no battery?

Yes. The phone will pull the necessary power for download mode and the Odin flash from the USB port. Just be sure to use a primary USB port (usually the ones on the back of the computer), rather than a hub, as the hub tends to cause problems.

Battery level LIES!

My 727 (AT&T) is rooted stock rom. The battery indicator gets 'stuck' a lot of the time. It happens in both a widget and the default battery indicator in the status line.. They will both show 100% and I know full well that they CAN'T be at 100% after sitting around all afternoon off the charger. I restart the phone and immediately it drops to 42% ...
Anybody else seen an issue like this?
A lot all over. Do a search

what i suggest you do is calibrate the battery.
1 plug it in and charge it to 100%
2 turn off the phone and charge it until it says 100%
3 unplug and turn it on and leave it for 3min.
4 turn it off and plug it in and let it sit until it says 100% again
5 repeat step 3
6 unplug turn on the phone and use it until it hits 0% and turns off
7 plug in the phone and let it charge to 100%
now use as normal and after a few days your battery will read more accuratley and more importantly, will last longer. keep in mind your battery does lie to you but just use the phone and you'll start getting more out of it.
moving forward, charge whenever you can. Lithium ion batteries will last longer if they're charged often (like at 60%-40%).

Yeah, I even downloaded the utility that removes the battery life file, and creates a new one. I guess I need to try one of these procedures again.. I honestly think it is more to do with a bad application, no matter what the battery life meter should not 'hang', and if it does for more than a few minutes, then it should be able to recover by forcing a restart of the app... *sigh*...
This is a common issue with this phone. Look up "battery stuck at 100%" in Google and you'll find quite a few results. Supposedly it's an issue with certain chargers not giving out proper levels so it trips out some indicator chips in the battery and/or phone.

Just reboot your phone and use the stock charger and cable from now on.
I had this issue with the rooted kernel (can't remember which one) but after downloading "battery calibration" from the market and following the in-app instructions the problem was solved.
