battery calibration?

hi!
don't know if this is the right forum, but i think i'll give it a try
how can i calibrate the battery of my hd2? or is this not neccessary?
should i always discharge 'till the battery is nearly empty, or is this not a good idea and i should recharge at a certain battery-level the latest?
thanks very much for your help!

im getting v good battery usage and i do thid by full charge full drain 3 or 4 times and i tend to charge when gets to 10% hope this helps g

i think the hd2 general forum would have been more appropriate for this but i guess it won't hurt anyone if you posted here
there are many contrasting views about this and you will probably get confusing answers. i am not an expert but i'll try to brief you with some info i've got from my readings about lithium-ion batteries and my personal experience, of course.
so here we go:

1. discharge fully until the phone shuts down by itself
2. remove battery and wait ~1 minute
3. charge completely with the phone OFF until the green light is lit
4. remove battery and wait ~2 minutes

some recommend to do it every 3 to 6 month
here you'll find many that recommend you to do it after flashing a new radio rom.
from my own experience i tend to agree with this

i've read somewhere that lithium-ion batteries like being charged as often as possible and don't like being left without juice. this is the main reason some people don't want to even hear about the calibration procedure. but i think there is a big difference between complete discharging now-and-then and complete discharging as a habit.
i've never heard anybody recommend a precise low level limit when you should start to recharge.
there is no danger to overcharge though.

[Question] BatteryLife increase?

I heard that the battery life will get better if i get my battery often down (0%) and then full loaded again
Can you give me information about ? True or lie?

Well, it is a well known good practice to let the phone switch off itself due to low battery and charging it completely while switched off. You can do this while sleeping at night; hence less chances of missing important calls. Though most of us cannot do this in real life; it is recommended for first 10 charge-discharge cycles of a new battery to ensure good life.

Why do you do unuseful posts in the developement area???? Didn't you see the f*****g q & a sticky above???

did you see that ive posted with the android app? because of that i didnt see sticky threads, sorry for that

i dont think frequently discharging to 0% is a good idea for battery life!!
just use the battery calibrator app from market and calibrate battery when voltage reaches around 4192mV
n if ur problem is solved then edit the thread topic to include [closed]

^^ Well in practice, the phone doesn't allow the battery to deep-discharge or 0% absolutely...

It is just the hype and worked for older battery type but we have lithium ion battery they don't work this way. I know there are so many members here who will against me in this thought but this is what I understand from so many forums.
One time battery calibration is good idea specially when you install custom rom and there is an app for it in market. It delete battery data when phone reached to 100%.
Realty is if you want good and longer battery life for lithium ion battery then charge frequently and best charging % range is 25 to 35% but not mandatory.

Yup. that's true. Also deleting battery stats when at 100% is not the final step. Make sure that the voltage is around 4190mV when at 100%. Max is 4200mV.
Read somewhere that due to miscalibration battery will be shown as 100% even though the peak voltage hasn't been reached yet.

With the right kernel you can get even 3 days of battery life. This with the EU version, 4g might drain a bit more juice.

WOW! your ''moderate'' usage must be higher than mine. I use hypersense nov aon stock battery and usually get ~2-3 days. And even more on cm or miui. I would suggest the andida battery. There is a thread floting around here.

Extended Batteries wid new back cover
Guys, after doing some searching, i think if i need extended batteries i need to get it along with the new back cover. so i hv found these 3200mah batteries from Seidio and Mugen

http://www.seidioonline.com/htc-nexus-one-innocell-3200-extended-battery-black-p/bacy32hnx1-bk.htm
nw my question is do u guys use any one of these ? and they really worth the money and do they last more? pls help me with ur valuable suggestions.
thanx

I was going to do that Big Battery thing but if you search on the forums you will find a database of Battery test and the dollar to performance ratio isn't great... those 3200 mAh batteries give you actually somewhere around 2400-1800 mAh.
OG Battery Test Thread
Battery test DB

Try Gingerbread For moderate usage it worked more than a day for me
Use Cm7 2.3.5
I have FLASHED ics now though .
+ i had installed juice defender it saved alot of battery for me whn AFK.

Andida 1800 looks like a good bet specially because there is no need for changing back cover

Q
How to unlock network for Google nexus one..

case or any way to improve battery life

hello guys.
i am satisfied with mi 5 battery life while using wifi.
but when i use simcard net ( 3g or lte ) , the battery drains so much fast.
less than 3-4 hours of sot.
so i want to know is there any way or external power case for increasing the battery life ?
ty.

I second this. I haven't been able to find any "battery case" for this phone. Any help would be awesome.

Just curious to what ROMs and apps are you guys using regularly?

at getting regularly about 6 hours SOT in like 2 days of usage....
using Mi-Globe Rom stable 8.1.6.0
better flash a good rom and optimize it...

I have the same small battery life trouble..
I tested w/ many miui and custom roms and optimized as much as possible but it did not help.
My case is quite weird that even power on or off, with sim inserted or not and Flight mod on or off does not differ the usage grafic drop down line and time..
Total battery life is 5-7% per hour.
Despite replacing battery w/ a new one the result remains the same..

I would recommend do a complete wipe even for internal storage and flashing global stable or nauget beta from miflash tool......Then give it a few days ...Should work

What rom you use? im used MultiROM 8.1.6.0 only charge 1 time for 2 day use.
Everyday my mi5 just for call 2 hours, spotify 2 hours, checking email and other stuff like facebook, xda, miui forum 2 hours.

Why don't consider getting those power bank case? Those that slip behind the phone and a charger tip goes to the charging port.

[AKT] Advanced Kernel Tweaks v1.4 BETA | Insane Battery & Performance (SD820/1|OP3/T)
I found this. I think it works with the SD820/820 Lite inside the Mi5. I will take my Mi5 next week and try this.
