My htc amaze doesn't display battery % correctly all the time.
How can I calibrate my battery? I see a bunch of methods but Im not sure whats best for the amaze
Im useing bulletproof 2.1.0 and faux .008 beta 4
thanks!
what has worked for me with bulletproof is to drain the battery to under 15%, charge it overnight, boot into recovery and wipe the battery stats.
will try it, thanks

so i figured out that my phone doesn't read my battery life correctly anymore, it will be at 39% and shut down, then i turn on my phone it will have 4% and itll turn off right away so i plug in my charger and it'll have 55%
dont really understand whats going on any help?
I just used this app and it worked, it reads the percentage just fine
https://market.android.com/details?id=com.nema.batterycalibration&hl=en
I havent been able to get my battery to stay at 100%, just says 99% and i have to guess when its fully charged. wiped battery stats and everything. running the same ROM

As the app says, all it does it delete the batterystats file. Use root explorer and go delete /data/system/batterystats.bin and you accomplished the same thing as that "app"

I get the same thing.. and because the device doesn't die all the way(at about 1% it does a soft power off) I can't get it calibrated right.
I'm using senseless, and I think it is more than the battery stats file.. tonight it was at 40%, started bootlooping for no apparent reason.. pulled the battery, rebooted and it said it was at 13%.
It has been a solid rom in a lot of senses(pun?), but I may try something else because of the quirks it has been having..

thats what was happening to me, i did a full wipe, using bulletproof, then calibrate, Im still testing but so far it reads fine, will update if everything is working fine in a couple of days.
another method is abit troublesome...
1. charge your phone battery till full (off mode)
2.when full unplug it, and open up the cover
3. take off the battery and left it there over 90sec or more..
4. put back the battery n bootup your phone.. it should calibrate..
if your battery is used too long it might your battery problem

I'm only a two week owner of the Amaze, but I've found curious differences between the stock battery and the Anker (1900 mAh). First, the stock battery will remain at 100% for a fair length of time before starting to drop (sorry, I haven't quantified it, but it's easily half hour to 45 mins even after making a call or two). However, the Anker battery drops off of 100% pretty quickly, as little as 10 minutes without doing anything. Admittedly, I've cycled the stock battery a few more times than the Anker, and even Anker says it takes 4 to 5 full charge and discharges to reach best performance, but I don't recall the stock being that quick to drop even after the 1st full charge. I haven't used the Anker enough yet to have a feel of whether the Anker will last longer overall, though.
Off topic, but somewhat related - The Anker charger doesn't seem to charge the battery to a full 100% - either the Anker battery or the original. In both cases, as soon as I install the battery from the Anker charger, the Amaze meter indicates just 96%. I even left it plugged in for another hour after the light turned blue, but it didn't help. Not a biggie, just an observation.
BTW, I got this from someone else who had already posted it, but according to a Google Engineer it seems that resetting battery statistics doesn't help. Read about it here: http://www.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer

exactly lol. my battery will stay at 100% (99% according to bulletproof) for a long time then once it drops it drops fast
I left my phone off while charging, and I'm having good results.. only weird thing is that it slowly flashes on and off the orange light and never shows green while powered *off* and on the charger.. I can't find anything that shows this is normal. Is it supposed to get to a green light when powered off and charging?

Not battery life.
Today i noticed my battery meter has been sticking, any way to fix that? It'll drop 20% upon reboot.
Today i noticed that my battery would spike up from 95% to 100% while charging and not go anywhere in between,. Is that normal? Battery calibration app kept going off early, and then as soon as it hit 100% i unplugged it without calibrating it, and it dropped to 99%. Happened twice in five minutes.
Also, instead of using clockwork recovery, i use Battery Calibration app to wipe my batt stats.
What mV should i be on?
One last thing, how do you bump charge? And is it really that unsafe?

I noticed this yesterday, I had my phone plugged in and it was at 94-95% and 2 minutes later it was at 100%.
To bump charge, once your phone is at 100%, unplug your phone power it down then replug it in. Once it shows the green LED meaning 100% charged boot your phone up and keep it plugged in. Might go back to being orange saying its not 100% yet so let it get to 100%. Unplug it and replug it back in a couple times until every time you plug it in it shows green for 100%.
I would think that it would be bad for the battery if you do this every day, but I can't give a definite answer for that. I use Battery Calibration to do that too, but between today and yesterday after I flashed over the new CDMA/LTE radio leak from the Radio thread my battery life hasn't been great. Considering going back to the stock radio.
I've noticed similar things on my bolt and even my dinc. To counteract this, I stopped looking at the battery % and got battery left instead. This app tells you how much longer your battery will last in hours rather than %. I no longer freak out about my battery life, %, or what others are getting; I've never been happier.

Sounds like a good idea especially for me lol. I noticed this morning that my phone was 56%, down from 74%. 18% drain over the time span of like 6-7 hours or so while I was sleeping. Not sure how good or bad that is, but for me it was just like wow.
You're being anal. Don't worry about it. Your phone is working fine. The battery level will appear to jump around a bit, especially when going on/off charger, or rebooting. Search around if you feel a need to know why.
So i am a recent convert coming from a RAZR and would like to know whats the best way to train the battery. The RAZR was horrible.
What do you mean train it?
I think he means as far as calibrate it from the beginning. Usually when I take a phone outta the box ill let the battery dir from there. No immediate charge. And then ill charge it and let it completely die 3 times. Done that with all my devices in the past few years and usually works like a charm. But when root comes we can add battery tweaks and such. My battery right now isn't too bad, but my EVO 3D was a lil better. I love this frkken phone

The app battery calibration from the market works well too
I have noticed that when looking in the battery usage monitor it seems that the battery hits full charge then drops to 96% and hits full charge again about ten times a night. Kind of bizarre, and probably contributing to the battery life being shorter. Also noticed that the 2750mah battery is read as 2720mah on multiple extended batteries.

After flashing a Rom you have to calibrate battery by letting it drain fully and then fully recharge so can't be that hurtful. Now letting it sit at 0% for 5 hours is not such a good idea.

Do most of you guys keep your phones plugged in (charging) as long as you are around a USB port/wall outlet or not? Unless I buy a battery booster, I don't like the thought of my phone being any less than topped off in the event that I can't charge it for a while. I'm aware that the battery can't be over-charged, but keeping it at 100% so much of the time doesn't seem like a good way to treat it. :/
Won't hurt it , people in the office have been doing it forever.

Everything you do with your phone stresses your battery.
Point being... As reverepats said... For the first few charges its good to drain it down then full charge it back up. Your not hurting the battery in such a way its going to noticeably shorten the life span.
This by the way doesnt do much for the battery itself... More for the OS. The OS compiles statics on usage, etc... This helps the OS "learn" the battery.
Now to counter point I made above...
The OS will also learn the battery over time... By doing cycle charges you are only speeding it up some. I still recommend cycle charging. I try to do it about once a week.
The best way to train/calibrate the battery in my opinion is to charge it till the green notification light comes on with the phone on. Then unplug the charger from the phone and then turn off the phone. Once it is completely off plug it back into the charger and charge it until the green notification light comes on. Then unplug the charger from the phone and then turn on the phone. Once the phone is done booting up and everything is loaded and what not then charge it till the green notification light comes on and then unplug it and you have now successfully trained/calibrated your battery.
I did this with my Rezound when I first got it and when I got my extended battery and the phone lasts me 24-36 hours with moderate use and Juice Defender installed. I hope this helps

But, but, that requires me to leave this beautiful phone turned off for a while, I'm not sure I can survive that torture...
When I charge my phone it only charges to 99%. I'll leave it in for a while, come back and it's only at 99%. Either charging in the wall, or on the computer. It used to make it to 100% then all of a sudden it just stays at 99% regardless how long it charges. So the charging light always stays on and never lets me know when it's fully charged.
Any idea why?
Thanks.
Mine does that too once in a while, randomly.
But the Sensation would do that to randomly.
Dunno why.
Battery is strange...
I get that too. But eventually it will get to 100%. There has been times where it was charged to 100% then suddenly drop to 99% even though it still plugged in.
Did you get your phone recently? I'm thinking its because the battery needs to be conditioned.
Mines always does that, as soon as I unplug it it jumps to 98%. Im hoping ARHD fixes this
I've installed Battery Widget (from Market) and it reports 100%. I plug in every night and in the morning it reads 100%.

New Amaze Android Revolution HD ROM by mike1986?
This happens with many devices. I have not seen this yet on my Amaze but I am sure at some point it will happen. Try turning the phone off and charging it to 100% then power it on also try running the battery all the way down and letting it charge to full UNINTERRUPTED over night. If those dont help you can always try another rom with better battery management or go into a t-mobile store and get a battery replacement if your battery is still under warranty. Hope this helps
HTC does this on a lot of phones. It is a safety default to keep the battery healthy and safe. I had this issue with the Evo. The only way to fully charge a battery is to have other a wall charger or a SBC kernel.
its the best sense rom known to man in my opinion.

My stock battery is 3.8v, and it only goes to 100% if I charge it in the phone. If I use my wall charger, it shows up at 99% when I put it back in my phone. I have two aftermarket batteries that show about 98% when charged from the wall. I am thinking that the phone charging circuit is set for 3.8v, and might possibly overheat the aftermarket batteries (3.7v). I saw one review that said these batteries melted the top of his SIM card. I'm not planning on trying that; I use the stock, charging every night, and swap the spares in if I run out of charge during the day.
I just remember hearing the same stories when I had my evo. You could charge for hours and unplug it and it would almost immediately drop to 99 or 98. So my previous statement may or may not help.
I charged mine over nite and woke up to it being 99%, left it for another hour or two and it hit 100%. I would say to leave it a little longer to get that last 1%.

I find that if my phone its powered off while charging, it shows 100. If powered on, it shoes 99.
Sent from my Dell Streak 7 using xda premium
this is normal for lithium ion batteries...it also depends how the manufacturer perceives the battery...some manufeacturers say that your phone is 100 percent but it might only be around 95-98...overcharging lithium ions are bad...also some manufacturers say you have 10 percent left while you might actually have 15 or maybe to percent left...this is a fail safe method to shut off the phone and keep the battery from draining completely WHICH IS REALLY REALLY BAD FOR LITHIUM IONS...OVER CHARGING THE BATTERY IS BAD TOO...perhaps htc's thresh holds are a little different and actual to the real battery life.
also not a good idea to use your phone or any lithium ion device while its charging
powering off your phone to charge it overnight is the best idea to give you lithium ion a long life but this is not practical. this is why it says 100 percent when you turn off the phone and 99 when you're phone is off....it confuses the phone: " A portable device must be turned off during charge. This allows the battery to reach the set threshold voltage unhindered, and enables terminating charge on low current. A parasitic load (which means using phone or turning screen on while its charging) confuses the charger by depressing the battery voltage and preventing the current in the saturation stage to drop low. A battery may be fully charged, but the prevailing conditions prompt a continued charge. This causes undue battery stress and compromises safety."

I thought I would bring some info I highly pushed with the Thunderbolt and Evo 4G that applies here. IF YOU HAVE THE EXTENDED BATTERY, YOU WILL WANT TO DO THIS SO YOUR PHONE UTILIZES THE ENTIRE EXTENDED BATTERY. The phone comes with a smaller battery, so it's batterystats.bin file is set to see that battery. It may not charge your extended battery all the way as it will think it is done charging much sooner than it is. Not that you won't get longer battery life without doing this, but you can always get MOAR!
**Disclaimer**I am not responsible for anything you do to your phone, zombie apocalypse, or the fact your phone called your girl/guy at the wrong time**As always your mileage will vary, some phones work better than others**
This is a form of bump charging your phones. I used it today, and noticed beyond better battery life immediately. So let us get down to business.
[Step 1] You will need to plug the phone into your charger, and charge the phone until the Notification light turns green.
[Step 2] Unplug the charger, wait for the green light to go out, plug the charger back in and wait for the light to turn green again. Upon doing so, turn the phone off. You will need to have fast boot OFF.
[Step 3] Once the phone is off, wait for the light to turn green, and unplug your charger, wait for the green light to go out, and plug back in. Repeat this step for a total of 10 unplug, plug back ins. Don't panick if sometimes it takes much longer than other times to turn green. You are charging the battery past the "capacity" that batterystats.bin says the battery has, which we will come back to in a min. Power on your phone. If you do not, or cannot temp root skip step 4
[Step 4] If you are able to temp root, then you can make your battery even better. Using a root explorer, go to data/system/ and delete the file batterystats.bin and reboot your phone. DO NOT use any battery calibration apps from the market, and down the road when we get S-OFF Clockwork Mod to wipe the battery stats. There is a known issue with CWM where it doesn't work, and I have tested a few calibration apps that say they delete batterystats.bin, but the file is always there, with the same data in it after using the app. Only way I have seen that works is manually deleting it.
[Step 5] The Hardest part of all. Use your phone, do not plug the phone in once, until it hits the 15% mark and asks you to. Once you do plug it into charge, let it charge all the way back up. You are building the batterystats.bin file so it understands how much charge your battery can actually hold. FUTURE REFERENCE: you will need to do this everytime you factory reset the phone, everytime you flash a new rom, etc. I know we cannot do all this currently, but this guide will still provide usefulness down the road when we get S-OFF as you will want to calibrate the battery the same way.
****If there is anything you noticed i put in wrong, or questions let me know***HTC has supported this method, minus deleting batterystats on many of their phones, and yet again seems to work on the rezound as well.****
Or you could just download the free battery monitor widget by 3c and you will notice your green light turn on at "100%" but keep an eye on the mA being pushed into the phone. When the mA goes from a positive (green number) to a negative (red number) that's when you should unplug. You will notice that your rezound "thinks" its 100% about 10-25 min before it really is... Much easier than feeling tweeked out, plugging and unplugging multiple times. Just another option. Good post though for sure. As most would NOT benefit from the full extended potential the battery has to offer.

when the mA goes red though, is based off the batterstats.bin file. I was not even talking about when to unplug the phone. I am talking about allowing the android OS to see how battery it actually has to use. so you are talking about something different than I am.
**edit** wanted to add. Your phone hitting 100% may in all reality only be hitting say 95% for example, but your phone thinks it is 100% hence why you can turn your phone off when at 100% and it continues to charge.

when the mA goes red though, is based off the batterstats.bin file. I was not even talking about when to unplug the phone. I am talking about allowing the android OS to see how battery it actually has to use. so you are talking about something different than I am.

I'd be willing to agree we're both right
**edit** I did re-word my post before your response and my reply. Its funny how we're talking the same language, but bad timing. Lol

haha read it now. Was unaware that the rezound knew to keep charging. The Tbolt never did(atleast in the beginning as i stopped using it for awhile), and the Evo 4G never did either. I never thought to check this as HTC themselves never made mention of it charging past "100%" on its own.

Stupid phones! Just give us a bad ass device that's unlocked, so we can do what we want already! The majority of people with these devices have no clue of their potential anyway. I work for vzw Btw and just deleted all my pics of the Samsung "Fixthis" over rated and cheap feeling like all other Sammy's IMO. I'm keeping my rezound no matter what. Even though Chingy hooked my Tbolt up with mad unreleased ish. I just switch my sim back n forth as needed

I did the battery stats fix with my Inc a long time ago. When I popped on the Rezound extended battery I plugged in the charger and it took 4 hours to charge vs about 1 for the original. Now at the end of a full day I have about 70% left, so I'm pretty sure the Rezound is much better about figuring out battery stats then older HTC's. IMHO. I'd love to see some data to back me up though.

[Step 2] Unplug the charger, wait for the green light to go out, plug the charger back in and wait for the light to turn green again. Upon doing so, turn the phone off. You will need to have fast boot OFF.
[Step 3] Once the phone is off, wait for the light to turn green, and unplug your charger, wait for the green light to go out, and plug back in. Repeat this step for a total of 10 unplug, plug back ins. Don't panick if sometimes it takes much longer than other times to turn green. You are charging the battery past the "capacity" that batterystats.bin says the battery has, which we will come back to in a min. Reboot your phone. If you do not, or cannot temp root skip step 4

So, step 2 turn the phone off at the end. after step 3. u say to reboot?? so if the phone is already off.. u mean to turn it on. then turn it off? kinda doesnt make any sense. Unless by reboot, you mean to just simply turn the phone on. in which, u should probably word it "Power Up" not reboot.
so confused lol
Lithium batteries are charged by monitoring voltage first. The phone can monitor the mAh going in and out, but it really has no bearing on the charging. It does allow the phone to monitor the health of the battery by watching for capacity changes as it ages.
Bump charging gives a slight overcharge, this is why the battery lasts a little longer. Charging with the phone off is best for calibrating the battery stats and for battery life because the phone can actually fully charge the battery. It is not possible to fully charge the battery when the phone is powered on as the battery is in use.
Here is a link to a post I made about lithium type batteries and how they charge and the reasons for calibration. It should clear up some things about the batteries.
You can do a bit of a bump charge by charging the battery with the phone off, then when the LED turns green, pull the charger and let the battery settle a few minutes then plug it back in. The LED should not be green and it will charge at the fast constant voltage rate for a bit more. Let it charge about another hour then unplug, wait a few minutes and re-plug it in again. This can force in a few extra mAh.

I'll be honest I haven't looked at exactly how much of a change it results on the Rezound, but on the Evo 4G for example, we got more than a "few" extra mAh. I am glad to see someone agree with me, to an extent. I will say the way I listed it is the way provided by HTC back when the Evo came out. What you said to do, we tried with the Evo 4G and it didn't work quite as well. Maybe that is why you say only a few mAh.
The one thing I have missed from my Evo 4G days are the trickle charge kernels. I know everyone thought they were bad, but no one ever had real proof of them damaging a phone, hell I used trickle charging kernels only for well over a month everyday and never had any issues. I would love to see those come to the Rezound.
I did every trick in the book to increase battery life in my Droid Charge (bump charge, deleting batterstats.bin etc etc etc) .
I stream audio all day at work from either iheart radio or sirius online & that absolutely KILLS battery life. My Charge would kill a 3500 extended battery before the end of a long work day.
Now, I am getting awesome battery life from the 2750 extended battery on the Rezound. I bought two of the 2750 batteries with the phone as they where only $29 each at the time with the extended back.
I did no tricks at all other than fully charge and let it run down to about 2% a couple times. I have been using this phone the exact same way as the Charge & I have yet to go to the second battery. I stream all day & its still running when I walk in the house at the end of a LONG work day.

Good lord, am I the only one that doesn't look at their phone while it's charging? I prefer to be asleep and let it suck as much power as it can. I will try your method, but you might want to mention to use the stock charger, since it's been my experience that it's the only thing that actually charges the phone properly.

Well that is because the charger that comes with the phone is 1 amp, versus the charger say I bought to use in my car is about half an amp. Cause it was meant for older phones. same as using USB. USB will take forever to charge your phone.

Are you on 4g or 3g? With my extended battery and a full charge my phone will be dead after 10 hrs with hardly any use

4g.
I'm totally amazed at the battery life I'm getting. The reason I bought two extended batteries was because I figured I needed them.
I have had a ton of phones and not one of them could stream audio for 10hours straight, I don't care what battery you used.
Today, I went to work at around 8 am. I streamed both iheart radio and Sirius radio online for almost the entire day. When I got home around 6 pm it was running on fumes, but it hadn't shut down yet.
If I didn't stream anything it would run for days I think.

I don't understand why I'm getting so much battery life on this phone. It's exceeding expectations. Not that I'm complaining, but my experiences simply are not jiving with the results found by reviews like Engadget's. I have the official extended battery which is 2750MAh, but I had a 35**MAh one for my Droid X and it died faster under the same use. Considering I never lose LTE signal at home/work, and everything I do over it at work is using LTE, I just can't fathom how this MOTHER-F***ING BEAST of an amazing phone lasts like 20% longer on a 30% smaller battery over my Droid X. (I'm not going by the battery life indicator, but purposely letting it die so I know for certain.)
Also, yes, I understand they were using stock battery in the reviews; but I used that the first few days before going back and picking up an extended battery @ half off normal price.
I love this thing, and I love HTC for having a 1% battery indicator on the stock device.
Oh, by the way; should I really plug it in at 15% remaining? I thought you were supposed to let it die when training new battery life?

What/where is this 1% indicator?

Add a battery indicator widget; it goes in 1% increments. I'd LOVE it if you could have it show on the actual indicator on the notification bar, but I haven't found a way to do that; but I keep a battery life indicator on my main home screen, and yeah, 1% increments for the win.
Hey guys..
I noticed something weird on my galaxy s3. Whenever i charge my device till 100% and take it off from charger, it goes down to 99% immediatly. I thought it could be a bug in my current rom so i flashed another one. But the buf still exists. I even changed kernels. Still same problem. I am running latest foxhound rom
+franco r5 kernel right now.
Is there any solution for this bug?
Hope someone can help me.
Best regards

It is not a bug, that's how it is made.
If the phone charged to 100% and sat there for a long time, the battery would lose charge cycles and life faster. So what it does, is one of two things:
It will either NEVER actually charge to 100%, or
It will charge to 100%, take itself off the charger to about 95%, and then charge again to 100%, over and over.
HTC does the second one, I think the S3 does the first.
Thanks for the answer.
I didnt know that. Its just so weird because on every of my previous phones the battery stayed on 100%.
But anyways thanks

I know, I don't like it either haha. Some phones will even say "100%" right off the charger even if they're not actually at 100%, which is why sometimes you see people that take their phone off the charger at 100% and a few minutes later they are at 95, etc.
There have been a lot of questions about this in sammy roms, and also in the s1. And it got me thinking about it this way.
As soon as you disconnect the phone from the charger it's dropped to 99%. But in my head, I say it has had to have even used the most minimal amount of juice and is 'technically' no longer at 100%.
Some are saying other phones are reporting batteries on 100% for up to an hour after disconnecting from the charger. That might look great, but there is no way that is correct either, because it has to have used some juice in that hour.
Maybe samsung don't like pandering to the needs of the masses re battery use reporting. Maybe sammy is the only one reporting a correct level.
Me, I don't care. My phone lasts just fine. Are you getting better battery life than your last phone? Haven't I read that the 1x has ordinary battery life? Does it's percentage stay at 100% for a long time? If so, that would be a bit of a rip off to me.
I know sammy have included the option to show the battery percentage within the settings of the s3. I don't use it, and my battery indicator stays at 100% until the battery reaches about 90%. Works for me.
Batteries never charge to 100% anyways to avoid the battery over-charging and exploding

Charge stops at 54%
Hi,
My SIII e fully stock and a few days now it does not charge past 54%. i tried to drain the battery completely and charge it after ant same thing happened. I can leave it overnight charging and it stops at 54%. Any solutions?
Thanks,
