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.

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.

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.

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.

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?

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.

so i came from the evo 4G where people threw hissy fits both ways. There were people who would claim left and right that it is bad for the battery, that the battery will catch fire, melt, explode, what have you, and then there was the other like 80% of us who used trickle charging with out a problem.
personally, and what I seemed to notice, the like 6 people who actually claimed to have issues with trickle charging had purchased and were using super cheap chinese batteries.
So i am going to disagree, and say there will be no issue with trickle charging unless you start using cheap chinese batteries, and even then the percentage chance of you having an issue is so minor.
I have noticed that until it gets to 100% it gets awfully hot. If I leave it charged/plugged in all day its cool to the touch.

looking at battery monitor widget my phone after hitting 100% charge is pulling 180 or less mA while "idle" and the temp sits about 32-33C. Seems to keep the Voltage very very steady. Whatever HTC did I really doubt it will hurt your phone in anyway.
I don't think it will hurt the phone. I do think it will make the battery have even less life though. I.e, when you finally do unplug it, the battery won't last very long. Batteries need to be charged and discharged often to work well.
My laptop at home stays plugged in all the time. And when I unplug it, it lasts about 10 minutes on the battery. lol

No, my statement was 100% true. It might've been irrelevant because it's a different type of battery, but it was not false as you said.
I have read that LiOn batteries do not develop memories as bad as other types, but they still do to some extent. FWIW.
If you watch your phone, it stops charging when its full. I often pull the phone off the charger with less then 100 charge due to this and this is also why the bump charge will bump it back up too 100%
So leaving it plugged in ask day will have no harmful effects at all.

Personally I never shut my phone off, it's on 24/7/365, if I don't want to be bothered it goes into silent mode but is always on.
For me, I plug the phone in every night when I go to bed... when I wake up, I unplug it for a minute and then plug it back in. Normally when I wake up it's anywhere between 95-100% showing.... Once I'm done getting ready I grab the phone and off I go with a full charged battery.
Unlike some phones the android phones have never kept a 100% charge while plugged in... this is one thing I do miss from the iphone, it always kept it at 100% while plugged in. The android phones stop charging when it get's to 100% and start again at an unkown %.
There is no magic... the only reason for unplulgging it is to start the charging process again.
what's the exact name and publisher of that battery widget? i'd like to take a look at it.

Use the built in battery widget and see what you get.. it will display the actual percentage on the screen.
I doubt it's a problem, it should be capable of switching to a trickle or over to powering vs. charging in the circuitry. The worst thing you can do for these relative to the charge is drain them completely and let them sit drained. These days for the longest life, you'd keep it at around 3/4 charged, but it's not a huge difference in life usually. The reason for that is lithium batteries hold a native charge by default.

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. :/

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."

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

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

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?

My wifes x2 display is using 59% battery. Weve changed the timeout to 30s and brightness down really low. But her. Battery still dies very fast. Its only 2 months old. We ha e disabled bt wifi and gps. Any other tips?
One other question. When her phone dies she cannot plug it in and turn it on or it gets stuck on the motorola logo. Qe have to wait till droid boot animation to plug it in. Any ideas?
Sent from my DROID4 using xda premium
If you plug it in from off do you see the charging screen? Try plugging it in and holding the power button simultaneously if the phone is off.
Is the phone rooted and romd or stock?
Is it running 2.3.4?
Sent from my DROID X2 using xda premium
Its running 2.3.4 rooted but not romd. I had the phone for about a month and had no issues with it. However i never allowed it to die. Shes not a heavy user but my main concern is why the display uses 59% where my d4 uses only 26% on the same settings as hers. Can i unroot the phone in case i have to return it under warranty?
Sent from my DROID4 using xda premium
when the phone dies you need to plug it in and wait until the battery on charge only screen shows at least 10% before the system will, allow you to turn it on
if you have BSR installed tho, as soon as it dies you can plug it in and when BSR comes up you can just choose reboot system now.
and the reason you d4 uses less battery on screen it's because I believe it is an amoled screen, which consumes much, lower power levels than an LCD screen

Have you tried recalibrating the battery too?
No. How do i do that? Thanks
Sent from my DROID4 using xda premium
First, make sure the battery is completely charged, then boot into custom recovery (BSR). Go to advanced options (towards the bottom of the list) and there should be an option that says 'recalibrate battery'. Once you recalibrate it, reboot back into android. I usually always let my battery run completely out after doing a recalibration before recharging it after a re-cal. If you find on your first discharge after recalibrating that your phone tells you you've only got 20% left and it would normally only last an hour before, depending if it needed the re-cal it may last 2 hours. Those numbers are just hypotheticals. Point is, recalibrating lets android know it's for sure 100% full at the start, but it doesn't necesarily know the end point until it gets there by allowing a full discharge. Also, the lithium batteries our phones use do best when recharged around 15-20%. It's actually bad to let them completely discharge all the time. And if you have multiple batteries and one may be sitting for a while, it's best to store them between 30-40%. Let me know if you need any more clarification.
Im going to try that thank you
Sent from my DROID4 using xda premium
More importantly, if you are already rooted and such, why not run a custom ROM? CM7 and/or Eclipse should give you a good boost in battery life. Running CM7 my standard battery lasts 18-24 hours with light ish usage. And that's with my original battery from when the DX2 first came out. I also have an extended battery I am running right now, but don't have data on that one yet since it's still discharging now. I do know that swapping between batteries of different capacities pisses android off sometimes though lol. Aside from custom roms, there are scripts and apps/software-based mods that can help it significantly too. Namely, wifi vs 3g usage, turning 3g data off when your phone is not being used, etc... I started off with an original DX but VZW gave me a free upgrade to DX2 after my 6th warrantied DX. I miss Rubix's ROM and being able to overclock and undervolt... My DX would last 2+ days sometimes when I had it all dialed in.
Its now my wifes phone. Since she already has had time getting used to stock i doubt she'll let me put a rom on it lol. But ill try

Well fortunately you've got a Blur-based and AOSP-based option for it. I know what you mean though, my gf likes her Sense-based UI, but had to give it up for a semi-funtioning Eris. I think she is getting a Bionic sooner than later... HTC is garbage.

letting your battery die completely is not recommended no matter what you've been Told
Li-on batteries were designed to last longer when you don't let it die completely
start charging around 15%-10%, 5 is pushing it cuz its most likely gonna shut down before you see 5, trust me, it's bad for the life of tour battery to let it drain completely, just Google Li-on battery life, recommendations and u can read for yourself lol

Yeah I know you're not *supposed* to let them discharge all the way but sometimes you have to and sometimes it just happens. For instance, my extended battery that I just did a re-cal on the other day has been sitting at 1% for the past few hours and is currently reading 1day 12 hours of uptime. (I shut it off the other night though and it is still discharging from its initial charge that I did the re-cal on.) So if I would have recharged it at 5% or whatever, I would be losing a decent chunk of available battery because android thought it was empty when it really wasn't, thus skewing the battery's voltage window.

that will only happen with extended batteries or one of those "Chinese", aftermarket batteries
regardless, battery life of Li-on batteries will decrease from letting it completely discharge, the more times you do it, the less your battery health will be.(BTW when do you "have to" let it discharge completely? , I'm not "calling you out or trying to "make you look stupid" or anything, I'm just curious what you meant by that?)
when I say 15-5% don't look at it as when Android reports that percentage, the x2 will, NEVER show an extended battery percentage correctly no matter how many times you "calibrate" that's just how it goes, it doesn't realize there is a higher capacity battery in the device larger than 1500mah, what you wanna do is use a battery voltage widget to monitor battery left, when it starts to get around 3500mV is when you are gonna want to charge I believe, (I think that 3200 is completely dead, and 4200 is topped off)
also,, wiping battery stats is a useless practice, not long ago I believe a Google developer wrote about why it's useless, apparently battery stats only has to do with the battery use settings stats about which apps have used which amount of battery. the battery stats gets reset/wiped EVERY time you get to a near fill-full charge (hence why the battery use graph resets itself when u almost fully charged, if you stop charging around 60-70% it wont reset)

Thanks for pointing that out. I regularly swap between my standard and extended batteries (both straight from VZW) because I'm always out and about and have used re-cal's to keep the perceived percentages from being skewed since I like to know how much life I have left in my phone so I know if I am gonna be able to find my way home or not, lol. (I ride my bike far and wide.)
I remember reading a while back that every time you un-plug your phone from a full charge that battery bin file gets re-written as 100%. So regardless of what android reports, yes, you will always get to use your battery until it is fully dead, but when swapping between two different capacities of batteries the reported percentages get skewed. And as I mentioned before, more often than not I am far from home on a bicycle in a city I only know a fraction of, and many nights somewhat inebriated, haha. I <3 my android, but it can certainly be a lot of work to keep up with.
