I am getting an extended battery for a non rooted phone. Is there any way to calibrate this without recovery?
Thanks for help
The best way would be to bump-charge your battery (with your phone off and no more than 2 bumps) then turn your phone on and use it until it goes down to 0.
This ultimately calibrates it. It may not be perfect after this, but after a few days it should be well calibrated.
The more you use it the more it calibrates.

Turned on my Desire HD today and used CurrentWidget during the first charge, now its on 100%. But when should I calibrate the battery?
- Can I do it right away, or should I wait for the battery to be drained?
- Should I calibrate it with the phone being all new, or should I do it when I feel like the battery is getting worse? (Couple of months?)
I wouldnt recommend calibration until youve got at least a week of normal use under your belt or you wont see any kind of improvement
When u notice unusual battery drain u could try to calibrate it but a new phone shouldnt need it perse.

I seem to get really excellent battery life when I wipe batterystats.bin after recharging to 100% at night. After a couple recharge cycles, battery life starts to get a little worse each time. But if I wipe again after a recharge, it adds a good 4-5 hours to my battery life.
I don't know why my phone/battery work this way together - they just seem to. I am wondering if there is any downside to deleting batterystats.bin EVERY time I recharge? Is it harmful to the battery? I doubt it is a problem for the phone but maybe so?
Thanks for any advice.
[EDIT: I realized after posting that this maybe would be better in the Q&A section of forum. I would move it there myself but don't have rights to do that. I'm sorry.]
only need to do it once.... .. i do it once per new rom/kernel.... you have to let that stuff work itself out.... let it chill for a week or so... just run it....
....i put a new rom on... .then kernel.. after i get it configured.. that night i charge it over night to 100.... then before i take it off.. i delete batstat with root explorer.... then unplug it... let it go down... .. charge it back to 100... . i'm telling you.. well for me... my battery last awhile.....i'm on nightly cm with savzen kernel.
good luck!.... if anything..get you a 1800mah battery from ebay.. there like 2 with charger for 7.99~....

Well you only need to do it once after flashing, after that, its useless. You THINK you are getting better battery life, but you are not.
Is it harmful to the battery?

Does nothing to the battery, the battery will still hold the same charge as before, and discharge the same way. The only thing you are doing is resetting the OS's 0%-100% stats, which again, is only needed to be done once.
You may be getting better battery life because after deleting the file if you aren't following through with the rest of the calibration process. After deleting, are you letting it discharge fully, then charge fully without breaks? If not, do it that way once & you shouldn't need to do it again.
But to answer your question - no, it won't harm anything. If you aren't calibrating properly after each battery stats wipe, then it may mess with your battery life. Other than that, you've got nothing to worry about.

I have to agree with the OP. I've tried a few different calibration techniques, followed the instructions carefully, and let them run their course. But after running a fresh battery calibration there is a noticeable improvement that day - I swear I'm not imagining things... The % starts at 100, then SLOWLY makes it's way down to 90 the way I think it should. Normally that first 10% just disappears into thin air...
Hi every, I'll like to know some battery life tips because I think mine is to short at software level or maybe at hardware don't know yet. I've GNex 1.9.0 installed with Trinity kernel. I've also WiFi enabled, 3G enabled and PowerAmp running all the time but I notice my battery drains to fast. How I can fix this? Do I must re-calibrate the battery or something else? I'm totally lost on this topic so any help will be appreciated :good:
Yea I want this too

To recalibrate a lithium ion battery,
1) Discharge battery completely.
2) Charge battery completely.
Unfortunately, that's about it.
and there is no good extended battery case for the phone.
unless you want the current one which bulks up your phone 2x (i believe at 3800)
if only there was a morphie juice case for the gnex
I have the Sprint Galaxy s6, which is fine phone, except the battery is awful. If I unplug it from the charger at 6am, it's down to 12% by 1. Would a new rom help? I haven't rooted the phone yet, but if it'll improve the life of it I'll do it.
Just some input, I had an issue with the voicemail app the other day. After googling it, I found it was an issue on Samsung phones right now. You can look under battery setting to see if it's causing you issues. I'm rooted, so I disabled the app. But it killed my battery overnight, which has never happened to me before.
I use the Renegade rom. It says it patches some deep sleep issues, I'm not 100% sure what that means but it appears to help battery drain when the phone isn't in use. I also use the Unikernel kernel. I'd follow this guide to get rooted and install a recovery (this will trip knox, but if you're thinking about a custom rom you probably don't care). Backup your stock set up, then install the rom I named above (or any rom you like). Then use titanium backup to remove all the Samsung/Sprint bloat. I also use Greenify and apps that take advantage of the S6's AMOLED display (awsms, baconreader, etc.) Here's an AMOLED theme, too (use the Black Mod). I know that's a lot of time and work that shouldn't need done to get good battery, but if you want decent battery that should get it done. That's what I did and my battery is better than stock (usually lasts me all day with just short of 5 hour screen on time). Hope this was helpful!
Thanks for the advice. I've read that Android M is going to help with battery life, so I don't know if I should wait or not. (I probably won't)

in my experience the best thing that you can do to increase battery life is to remove bloat. That is why i use a heavily debloated ROM, and even with that I remove apps that I don't need.
Beyond that, I use Greenify and Wakelock Detector.
Except for heavy use, I typically can run my phone all day without needing a charge. That is all that I really need.
I've got a similar problem.
I factory reset recently, and just let my phone sit with nothing but Google Messenger and Facebook. It still dies from a full battery in ~4-5 hours, without me touching it. Thing is, all the battery stats show less than 5% usage. And there's no crazy crap like games, etc running. I can't figure out what's eating the battery.
I just put the phone in Airplane mode, and enabled Wifi. I'm getting all my emails, fb messages, gmail, google voice, so on. Battery only went down 30% in 28 hours. I turned off airplane mode (it's not connected to Sprint at the moment, I took it off the account), and I have an Airave...battery dropped 15% in about 30 minutes. Went back to airplane mode with Wifi on, and back to a really slow drain.
Right now, I'm planning on packing up my phone tomorrow and sending it to Samsung for a battery replacement. Because my standard 2A-5V can charge this phone from 10% to 100% in an hour...which isn't right.
every battery recalibrator i know of needs root. my phone likes to die at 25% because i made the mistake of getting an att phone.
anyone know of a battery recalibrator that will work without root, aka on our note 4?
i've tried the whole, discharge battery fully and charge it back up, this got me to where it would die around 4% which was an improvement, but now a week later its dying at 25% again..
It's so sad such an easily fixable bug can completely cripple my phone because it doesnt have root.
anyone know of a battery calibrator, or method, aside from just cycling my phone dead/full/dead/full over and over.
thanks.

Battery recalibration is just a placebo as long as you're using a stock battery. Ever since the Galaxy S2 days, battery calibration has become obsolete.
The only 2 exceptions are:
1) If you're using a cheap 3rd party battery, where they may claim that the mAh is equal to or greater than the stock battery, but in reality, it's so cheaply made that it's actually lower.
2) If you're using an extended battery that's a double or even triple layer/stack battery. In this case, the phone reads the battery incorrectly since it reads the battery stack-by-stack. In other words, when the first stack is nearly depleted, the phone will read the battery level at say 15%. Then, the second layer kicks in, and suddenly, it confuses the phone and it then thinks that it's got 40% battery left, then 60%, then 90%, etc.
The only solution to fix these two issues is to tweak the kernel (unlocked bootloader needed) or to just use a stock battery.
So in conclusion, I'd your phone isn't reading the battery level correctly, then it's most likely your battery. You'd want to get an OEM one and not some Chinese 3rd party battery.
