Battery calibration: for good battery life - Touch Viva, MDA Basic ROM Development

Battery calibration is simply done by running it down completely until the phone shuts off by itself...
Then remove the battery, wait 10 seconds, insert again, repeat...
If the phone shuts off again in less than a few minutes you're done.
Now remove battery and hold power button for 1minute.then insert battery.dont switch on the phone. plug the charger and recharge the battery fully until the green light is on...
then remove battery,hold power button for few seconds,insert it and switch on the phone...
yes its done......
do this initially once in 3-4months when the phone is new.then ince a month after a year to gain maximum battery performance...
REMEMBER THIS WILL NOT DRAMATICALLY IMPROVE YOUR BATTERY LIFE....
BUT THIS WILL SAVES YOUR NEW ONE TO BE DEAD BEFORE AGE
DONT EXPECT MORE FOR ALREADY SWOLLEN OR DIED BATTERY...

There are programs that drain battery by endless vibration... will that do? Or we must use the phone normally until power dries?

I don't think that draining battery by endless vibration is a good idea.
You can drain it by using heavy programs like windows media player, wifi etc.

Thanks...
Thx. Calibration done!

Another battery drain problem - driving me CRAZY!!

I know there are already a lot of discussions on battery drain and believe me, I have read every single one of them. However, I think mine is slightly different:
When fully charged and using WIFI for 10 minutes, 10% of juice will be used. Listening to MP3 for 1 hour will also use another 10%. Overall, battery life is really bad but the key is it only happened suddenly. It have been very good up till now.
I have tested this on another battery and have exactly the same results so it is not battery related. I have also hard reset the phone and tested the battery with nothing installed and it still drains. A full charge only lasts me like 4 hour of very light use.
I installed Battlog and the power consumption is around 90 which I think is pretty low, but at times, even with this low consumption, I can see the battery usage literally falling before my eyes, like 5 % in 5 minutes.
I have also tried the HTC battery test, i.e. fully charged the battery, turned on plane mode and full brightness. After one hour, it only used 8% which I thought is normal. However, if I start using the phone by just simply clicking around, it will start dropping.
I believe the phone is fine on standby but once it starts doing things, even simple operations like moving around folders, it starts consuming a lot of power.
This all happens after an overnight charging episode when I noticed that the light stays amber in the morning and the percentage stays at 80%. I soft reset the phone and it immediately show 100%. This has never happen again but my battery usage is never normal since.
All in all, I think it is somehow hardware related, like the battery gauge is bad or the charging is never complete but it still shows green. It is still under warranty but I think will be very difficult to convince the service centre that there is something genuinely wrong with the phone.
P.S. Should also mentioned that I am using the stock telstra rom and have also cycled through the batteries twice before testing.
I had the same problem...
You should try resetting you battery:
1: let your battery drain to 0%
2: fully charge your battery while keeping your phone off!
this solved the problem for me..

I had actually "reset" the battery but only drain it to 5% before recharging as I have read that it is not safe to drain to 0%. I'll try to completely drain it tonight and recharge. Will report back.
btw, I noticed that when the battery is charged to 100%, the led stays amber for about 15-20 minutes before turning green. Is this normal or should it turn green immediately after reaching 100%?
Tried completely draining the battery and charge overnight but have no effect. The problem persists. So this is definitely not a battery problem.
I guess the last thing I can try is charging the battery with a standalone charger or another HD to see if there is problem with the charging mechanism in my phone.
The latest Telstra rom seems a bit better on battery
led amber
The led amber must turn to green
immediately after unplugging.
some thing is wrong with your charge
system .

aidinali, can you please explain what you mean? I thought the led will go off if you unplugged the charger. My problem is that after reaching 100% as indicated on the phone, the led stays amber for another 15 minutes before turning green.
Well , I'll correct & explain more....
1-when you reach %100 ,the led will turn to green immediately (if you’r phone is plugged in).
2-if you unplug ,the led will turn off (as you said ).
The problem is that since the battery meter in HD has not been defined by percentage , it doesn't match with
Apps like battery level or battlog .so when you see %100 on them , it' s not "real % 100 ".
I believe there is something wrong with the phone as the percentage usage and charging status do not match. However, since the basic HTC software does not have any battery usage in percentage, it’s hard to convince the service centre that something is wrong.
Any software that shows the battery as a percentage all have the same reading, so I assume they all rely on the mainboard for that information. There is obviously something wrong with either the charging process of the phone or draining more battery than it needs during usage.
I have 100% exactly the same problem as in the original post.
Does anyone else?
I have also tried 2 batteries and had exactly the same results with both, so I also know it is not the battery. The only app I have installed other than Dutty's 6.5 rom is Tomtom which does not need to be run for any of these issues to occur.
Any chance on warranty? I think it's software...
Try a different ROM. I've been having the same problem. I just flashed a new ROM about an hour ago (partly because Dutty's 6.5 kept freezing). I'm hoping both problems will be solved now.
i've found the latest radio rom to make a big different to battery life. 1.14.25.24_radio
the previous radio rom (1.13?) did suck the juice and made battery last 2 days less than 1.14
Try charging with a different charger. Ie. connect a USB cable on your PC and charge it from there.
I've had very similar problems with the stock charger a month after i got my TouchHD, and ended up testing with my old P4350 charger and all problems went away.
I've had similar drains even witch WiFi off, no emails, exchange or 3G access...
Now i'm getting a whole day's usage and i'm left with 30-40% battery, with 2 hours average talk time
I've tried with a number of chargers.....battery still sucks.
I've just switched from Dutty's to Energy ROM, radio is 1.14
If anything...energy drains more quickly than Dutty's
It says it drawing 350mA
Ok, I've used Energy ROM but now using Dutty's Leo. The only thing I've loaded so far is Battery Guard which say it's drawing 98mA when on standby(ie....backlight goes off). That'sa massive difference on the 250mA readings I used to get....now all I have todo is figure out which program I'm loading that is killing my battery.
That still only equates to 12 - 13 hours on a good standard battery with no use at all.

Standard battery should last longer. Sounds like your battery may be slightly faulty. Make sure you let battery drain fully before charging, and always try charging with device off. Should help improve strength.
I had same problem when i flashed miri's rom, hd got warm and didn't last, it cooled down in standby, the answer to my problem was that the wifi was not set to save battery mode, once i set it to save power everything was ok
Used 8% in 24 hours

Have been trying that for a month now....something seems to have suddenly worked It only used 8% of the battery in 24 hours! I live in the rainforest with no service so cellular was turned off...wifi on, but I only accessed it about 6 times......still,nothing has changed. The same conditions would leave me with a dead battery in 7 hours previously.
Time will tell if it keeps up this well.
By the way....Thanks
So basically you're saying people should drain down the battery to 1% or so and not to 0% (device dies when battery is out) to get a better battery strength?
Seems to be the general consensus. I'm still not sure if that's what made the difference for me but previously,I would put my device to standbye when I went to sleep at 10:30pm and it would be dead by 6am

yupz... u're right bro...
i am a flashing junkies and i always do this after flashing to WM 6.5 ROM.
last nite i've just flashing Onyx 5.1.1 ROM (the fastest WM6.5 ROM i felt) . well.. as expected from every WM6.5... battery drain veeeerry Fast!
i just use it normally till switched off on it's own. then charge the battery (while my elfin still turned off) and...
voila....
from 08 pm last nigt till 12.00 am today, it's only consumed 10%!!!
WOW!!!
in fact, i use G-alarm (which usually drain my battery faster in WM6.5).
and this morning, it's need 30 minutes my G-alarm ringing to woke me up.
YES I WANT THAT ALL MEMBER SHOULD TRY THIS AND GIVE THEIR FEEDBACK..
@saurabh bro i tried it...but it dnt workd...

this is called "POWER CYCLING"....when u hold your power button for a while when no battery inside it drain your backup battery which resposible for your device to remember date,time etc.....
after doing this all the power from the device will be gone....
after that u can do the procedure otherwise it will not gives u good results..
i have tested it myself
It works fine for me!
Now battery drain is proportional to the usage and for sure battery life is longer

Battery Drain is Broken ????

1st of all excuse me for my bad english.
I have a big problem with my N1 after a full charge in 4 hour and NO USE i have 32% of battery.
In 2 more hours i have no battery and request cable to charge and than shout-off-
I try different radio and rom and kernel
I wipe battery stat.
No way.
What i can try and if i need spare parts or service for my phone from USA and i'm in italy ??
Thanks.
Is your phone getting hot? I'm pretty sure, and it sounds like you agree, that this can't be a software problem.
Maybe bad battery? Is it a new N1? Any damage? Drops?
If your phone is getting warm it is most likely a software problem. Sounds like you just have a bad app in the background that won't stop, and it is running your CPU constantly.
Download a task manager (not for the auto-kill, auto-kill is bad) but use it to see if there is any app that is constantly using up your CPU.
Also download Spare Parts and check the battery history and see if anything is high on the "partial wake" screen.
i try 4 different rom, 2 radio e 3 kernel.
No changes
The phone never fall from my hand.
Yesterday i put in a LeoFroyo and just full charge and boot this morning 6:00 at 10:00 i have 40% of battery.
RMA ?
Ok yeah, sounds like a bad battery then, or worse.
Some news here.
I bought a new and original battery for N1 from HTC.
No solve the problem.
I fully charge battery and in 12 H is drained (also Time and Date reset).
I fully charge the battery and leave it out of the phone and NO DRAIN
I fully charge and put in the phone POWER OFF and is drained (cannot say in how many hours).
So the strange and new things are
1) Drain with the Nexus power off
2) No a battery problem
3) Reset time and date after drain
What can use battery in the phone when is power-off ?????
I write at HTC USA and Italy but they dot answer nothing. (2 weeks ago USA 1 week Ita) It's normal this delay ?
Actually powered off? Or do you just turn the screen off? Do you press and hold on the power button, then choose "Power off"?
12H is pretty good for the battery, considering it sounds like you have auto-updating things and use it a lot. If it is draining in 12H when you don't use it, you probably have installed an app that is misbehaving.
if you are losing battery power when the phone is off then this is a phone problem

PROPER battery calibration... is getting on my nerves :/

So, I am using MIUI 2.1.12 with LorDModUE 8.6 CFS 2WCR kernel.
I have installed 4EXT Recovery Controller and CurrentWidget.
With CurrentWidget, I monitored the battery while charging until it reached 0mA (which means the battery is as full as it can get).
With 4EXT Recovery Controller I removed the batterystats.bin file.
I drained the phone until it shut itself down. Then I charged it (without powering it on) until it was full (LED was green).
I power on the phone... 99% battery.
I plug in the charger... it says 26mA (which means it would reach 0mA as in full charge in another 20-30 minutes).
WHAT THE HELL?!
This never happened while I was using the default CM kernel included in MIUI. Only happened with Tiamat and LordMod.

Seriously, guys, what is the best way to calibrate the battery?! Perhaps I should not have let it shut itself down, but plug the charger when the phone was at 1% (which lasted for another 20-30 minutes, by the way)?!
if I don't remember it wrong the LED turns green at 90%.
afair the battery doesn't get charged during booting. which means that you probably lost the 1% during boot.
I also used the same method and got it calibrated correctly
but is their any other way too ?

The LED turns green on AOSP ROMs at 90%, when the phone is ON, as far as I know. When it is OFF, it works fine (goes green at 100%).
I want to hear from the developers / those that know how these codes work and stuff... Cause I don't want to look at my phone how the percentage goes down so fast, then, when it reaches 10%, I can play Pocket Legends for another 20 full minutes -.-

The battery doesn't charge to full capacity first time around. When I used to calibrate the battery I would charge until it was drawing 0mA, then reboot; it would be drawing about 26mA, so I'd charge to 0mA again and reboot; it would now be drawing about 15mA, so I'd carry on charging to 0mA, reboot, repeat, repeat and repeat until it eventually continued to draw 0mA after a reboot. Then I'd delete the batterystats.bin file.
As one of Google's engineers says, deleting your battery stats isn't going to improve your battery life. I haven't done any of that for a long time now and I've noticed precisely no difference (except for the extra time I've gained by not having to wait for it to finally charge up to full capacity).

I know about Google's statement.
The battery would drain fast, then, when it reaches 1% or 5%, you would be able to use your phone like it had 30%. Just that it shows the values wrong. Calibrating the battery should fix that...
Anyway... I'm not going to struggle any further.
I'll tell what I've done;
- I have installed Battery Balibration app and CurrentWidget,
- Waited battery charging till reached 0ma,
- Removed battery stats and restarted,
- Then waited to drain battery and shut-down itself,
- I connected USB charger to PC and TURN ON THE PHONE !!
- Again waited battery to reach 0 ma,
- Then plugged off and monitored that current widget shows the range btw 3-10 !!
I don't know exactly if it helps but, maybe you should turn on your DHD while carging..

I don't really know. It would be silly for the Android system to display the battery percentage (up there, in the status bar) by reading the batterystats.bin.
My phone's battery level drops somewhat fast, then, when it would reach 30% or so, it doesn't drop as fast. Also, at times, when I reach 10%, 5% or even 1%, I am still able to play an intensive game like Pocket Legends for an extended ammount of time (30 minutes, for example). Pocket Legends is CPU/GPU intensive and it also requires an active Internet connection, so I'd say it's pretty power hungry.
I don't really get the entire purpose of calibration. I have done it and I can't seem to notice any difference.
I'm going to do it again, now, because I switched to a Sense ROM (RunnyDrOiD). I'll monitor the battery with Battery Monitor Pro. When it reaches +0mA, I'll reboot and so forth so forth until it's drawing 0mA, although I doubt I'll resist that much time, so I'll just delete the batterystats.bin after a few reboots, when it reachs 0mA.

If everybody knew the meaning of the word "calibration" then nobody would talk such nonsense.
Calibration improves the accuracy of the percentage shown!
The illusion is that you improve your battery life with it....

As I said... calibrating the battery may fix the "problem" where once you reach 1% / 5% you can use your phone like it still had ~20%.

Hi there people, I didn't find any battery thread similar to what I'm going to say so I'll spam a little bit
I've just found as I was fooling around this: http://www.ebay.com.au/itm/PowerSki...AU_MobilePhoneAccessories&hash=item20c1a1c8ad
It suppose to be a silicon case with a battery build in(1500mah ..not bad), I don't know the dimensions but I just someone might think it as a solution to our 1230mah small battery(with this you have a total of 1730mah which is plenty)
P.S. To mods.. feel free to delete my post, I just wanted to inform the people about a solution that might be handy

Battery or system problem

I have problem with battery or system. When the battery is 100% charged, I wait a few minutes, then disconnect the power supply. I leave the phone, I don't use it. After a few minutes or longer, a few percent of the battery drops. After restarting the phone, thinking that some processes drain the battery, the battery indicator shows 100%. For example, before rebooting the battery indicator shows 93%. After restart, the battery indicator shows 100%. Battery percentages decrease faster before restarting. After a restart, a little slower. I don't know if it's the battery or the system's fault. I am currently using LineageOS 16. I don't have applications that could wake up the smartphone. I also use Greenify + Xposed.
The first 10-15% of battery drain much faster than the rest for me as well. Probably a calibration thing or maybe battery's bugging out., dunno. But I'm pretty sure it's not a system problem as my phone's working perfectly fine otherwise.

I bought new extended battery. Problem is gone. I have 6-9H SOT.
Most phones will lie about the battery percentage from 90%-100% due to how batteries are optimized.
