Anyone know a way to bypass the recalibration or extend the 28 days??

Does anyone know if there is a way to recondition a phone batter or at least test it to see how efficient it is?
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.
Hello folks,
For several months I lent my nexus 7 to my family, who don't have the slightest clue regarding battery health maintaining techniques.
So now when I obtained my tablet back, the battery life is less than stellar.
I get something like 2 days battery with 5 hours of screen on time (nothing abysmal of course) and I wanted to know if there are steps you can take to recover the battery potential.
Personally I take such steps as avoiding extreme heat or cold conditions, fully charging when battery drops to 20% and other similar tactics.
I am currently running CleanRom with Glitch kernel.
Wondering if it's possible to somewhat recondition the battery?

I do not believe modern Li-Ion batteries retain any type of battery "memory." Meaning, like on older nickel-cad batteries, if you did not cycle the battery properly they would lose ability to maintain charge.
So, to answer your question, no. I do not believe you can gain any battery health back via charging cycles.
Try calibrating the battery using an app(requires root),also let the tablet fully discharge until it powers off and then charge it to 100%.
That's what I can think of. Hope it helps.

THank you
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.

Hi ... I have a question about bn31 battery ... how do I know if the battery life is still good?
Using the multimeter, it marks 4.20v ... it means that this good or I need to change? the cell phone is not lasting for 6hrs of use and the battery is gone. Would you like to know if it's really the battery or have something else with the phone?
Use AIDA64 app to check battery health
Hi. Thanks for informativo. But i want anything more physical...no app...i don't believe much in the app's :good:

Used AccuBattery and then use your phone as normal and let it charge for 4-5 times, then you will get the estimate battery health left from your phone. Screenshot is from my Mi A2.
You know it's good if it doesn't look like this:
Late reply.
I'm using AccuBattery App since March 2019 and its working very well for My MiA1. I trust it after cross-checking with alternate indicators.
Most important is the time spent in Deep Sleep. If you get zero or small percentage of time in this mode even after overnight inactivity, your mobile has background apps that are consuming battery.
I have been using Greenify App for many years and it helps cleaning up. I think it's a necessary App.
Try the following:
Shut down the phone. Reboot from Cold.
Put the Battery Saver ON w/o doing any other app launch.
Do the same thing first, after every Charging.
Every morning, I check the Deep Sleep. I do get additional ~6hrs (same as your sleep time). The average discharge rate falls to 1 to 1.5%/h.
AccuBattery does help, working consistently for last 8 months.
